Statistical Evaluation of the Correlations between Socioeconomic Factors and
the Amount of Trihalomethane in Drinking Water in the State of NY
Trihalomethanes are common byproducts of disinfection processes in public water systems. The relationships between the total amount of trihalomethanes in public water systems in New York and the corresponding socioeconomic variables were studied. A significant amount of chemical and demographic information representing 81% of the NY state population, was obtained from the NY State Department of Health, the US Environmental Protection Agency, and the US Census Bureau. Statistical tools such as Pearson Coefficients with P-values, Grubbs test, and Mean Comparison using Student's t-test were adopted to evaluate the correlations of total trihalomethanes concentration and various socioeconomic factors. Data analysis found negative correlations between the total amount of trihalomethanes and socioeconomic factors, such as mean household income, Asian percentage, and Hispanic percentage. In addition, the water source and the size of the public water system are considered critical factors. The lowest concentrations of total trihalomethanes were detected in communities served by groundwater with higher median household income and higher Asian populations.
Breakthroughs in Honey Bee Health:
Local Summer Weather Humidity Conditions Influence Winter Colony Survival (Part III)
Honey bees (Apis mellifera) are a vital species in our ecosystem. They pollinate 73% of the world’s cultivated crops and have an economic impact of $20 billion in the United States and $183 billion dollars globally. Unfortunately, in 2006, beekeepers reported colony losses of 60-90%. Commercial beehives in the US have decreased over 50% in the last 70 years. The greatest single contributor to the decline of honey bee health is the Varroa destructor mite. Currently, all commercially available thymol-centered systems are gel-based and work by direct contact with the mite. These systems are also highly dependent on temperature and humidity for effectiveness. An earlier laboratory investigation (Part I) and field study (Part II) examined the use of thymol-based essential oil for miticide efficacy and the effective use of mist diffusers to eliminate the dependence of the essential oils on temperature and humidity conditions. Recognizing the significance and impact of hive humidity to Varroa mite survival and honey bee Varroa mortality, a linear regression model analysis was developed to investigate the significance of weather-related variables, particularly temperature and humidity, to colony loss. Weather data was collected from the National Oceanic and Atmospheric Administration (NOAA) and the National Centers for Environmental Information. Percent colony loss data was provided by the Bee Informed Partnership from 2009-2021 for the state of New Jersey. To date, this research represents the first and only available study examining local weather-related humidity variables to colony losses. The summer humidity-related weather variables of relative humidity, dewpoint, vapor pressure deficit, and temperature were found to be statistically significant to the percent of winter colony losses.
Enhancing American Football Analytics:
Classifying Play Videos as Run or Pass using Deep Learning
High school football coaches often rely on reviewing past season game footage to develop winning strategies. Identifying recurring patterns in the opposing team's offensive plays through video analysis helps coaches plan effective defensive tactics. However, accurately classifying play types from video clips using automated methods remains challenging and obtaining a sizable dataset of labeled plays for training models is difficult. This paper proposes a machine learning-based approach that utilizes the MoViNets model for action recognition. To overcome the challenge of limited labeled video clips, this paper utilized transfer learning to fine-tune MoViNets models that are pre-trained using a large dataset Kinetics-600. Extensive experiments were conducted to determine the optimal sampling scheme for the videos and compared the performance of two variants of MoViNets, the smaller A0 model and the scaled-up A3 model. The results show that using 24 frames sampled at 2 frames per second yields the best classification performance, and the A3 model achieves 81% accuracy on the test dataset, outperforming the A0 model's 74%. Ongoing data collection is expected to further improve the model's accuracy, potentially enabling automated play type classification.
Evaluating the Effect of Potential Career-Altering Injuries on NBA Athletes
This project aimed to evaluate the effect of three major injuries on the post-recovery performance of athletes in the National Basketball Association (NBA): anterior cruciate ligament (ACL) tears, Achilles tendon tears, and meniscus tears. All three are crucial in stabilizing the body during strenuous movements, such as pivoting, jumping, or accelerating. Recovery from these injuries takes many months and can change an athlete's career trajectory. A dataset with every NBA player who has suffered one of the three named injuries in the past twelve seasons was curated (n=113), with information about each player's overall impact on the court before and after injury and some characteristics that may determine post-injury performance. The data was run through various data analysis models, including multiple regression and decision tree classification. This study was the first to use newer statistical metrics such as LEBRON to evaluate player performances, as well as the first to combine the three injuries for direct comparison. The return rates for ACL, Achilles, and meniscus injuries were 85.7%, 96.3%, and 88.6%, respectively. Results indicated that age and average minutes per game pre-injury were the most important factors in determining a player’s post-recovery performance. Furthermore, Achilles injuries harmed offensive impact more than ACL or meniscus injuries. However, they were more likely the result of over-usage and, therefore, less likely to end a player’s career. Finally, those who previously suffered a similar injury performed significantly worse than those who did not.
Lyme Disease: A Grand Challenge
Lyme disease (Lyme borreliosis), first discovered in 1908, is the most common vector-borne disease in the United States, with around 476,000 new cases per year. As a global disease, the impact of Lyme disease is such that it should be thought of as one of the Grand Challenges in Global Health. Despite its pervasiveness, there are very few approved tests that are accurate in detecting it. Similarly, there are even fewer treatments for Lyme disease after it passes its initial stages. It is vital for the medical community and the general public to further educate themselves on the early symptoms of Lyme disease and the overall prevalence of vector-borne illnesses so that they can be treated before they suffer immense repercussions. Moreover, further research needs to be done into treatments, testing, and the impact of climate change on disease risk.
The Importance of Social Class and Gender in Identity
Identity plays a predominant role in today’s society. According to the Oxford Dictionary, identity is “the fact of being who or what a person or thing is.” Despite its rather simple definition, identity is extremely important in society because it drives political affiliation, school selection, occupational paths, and other important components of life. Social class and gender are two important aspects of identity. An individual’s social class is correlated with political views, finances, education, and opinions about minorities and immigrants. Divisions created by gender also influence identity. Historically, women have often been discriminated against because of society's views of gender roles. Although there are multiple examples of women being treated differently than men, this is particularly prevalent in politics. This article examined how social class and gender can have a negative or positive impact on an individual and society in terms of various opportunities ranging from education, finances, and politics. It will be necessary for changes to continue to occur in social class and gender inequalities in order to improve upon an individual’s identity, resulting in societal inclusion and evolution. We will discuss ideas to resolve these socioeconomic inequalities and the lack of political opportunities for women.
Measuring the Effect of the Pandemic on Music Practicing Time and Motivation
The COVID-19 pandemic had a large impact on the world as a whole. The pandemic had a particular impact on musicians, replacing live performances and in-person lessons with recorded performances and remote lessons during lockdown. Disruptions and uncertainty caused by the pandemic have created great change in the lives and schedules of music students, which has been observed by several recent studies. Such studies focus on adult classical musicians, but this study aims to observe school-age music students. In the current study, American music students filled out a survey measuring demographic data and descriptive data about practice time, feelings of threat, and feelings of uncertainty. I hypothesized that practice time would be affected by the pandemic, as well as feelings of motivation, threat, and uncertainty. I found that none of the above held a strong correlation with practice time. However, I also found a significant relationship (p<0.05) between years played and motivation to practice. Changes in lesson format positively affected student motivation and practice times, and overall motivation and effectiveness of lessons were positively affected by years of musical experience.
Stem Cell Therapies for Lung Cancer Patients with a History of Tobacco Use
Lung cancer is the most commonly diagnosed cancer in both men and women. There are two main types of lung cancer, small cell carcinoma, and non-small cell carcinoma. Non-small cell carcinoma is more common and less aggressive than small cell carcinoma. Lung cancer is more commonly diagnosed in its later stages, making it harder to treat in the long run. The leading cause of small cell carcinoma is smoking and using tobacco products. The current treatments generally do not have a high success rate, specifically for patients with small cell lung cancer. A new treatment method that can change the course of cancer treatment in the future: stem cell therapy. Stem cell therapy can repair the lungs of small cell carcinoma patients and provide them with the needed cells for their lungs to return to normal function. The stem cells would be removed from the skin or blood of the patient and genetically transformed into embryonic stem cells, which provide more utility for the stem cells in the body. Once they are modified, these stem cells can be transferred to the body through in vitro scaffolds, tissue-engineered scaffolds, and local injections. After the transfer has occurred, the stem cells would be able to rebuild the lungs and help the body return to normal conditions.
Barriers to Eating Disorder Treatment:
A Review of Socioeconomic Obstacles and Gaps in the Healthcare System
With an increasing number of cases every year, eating disorders have the highest mortality rate of all mental illnesses globally. However, more than half of the diagnosed patients do not receive suitable treatment. This paper identified the barriers to both mental and physical care in eating disorder treatment and their impacts on patients’ course of recovery. The reasons for these obstacles are highlighted based on patients’ personal experiences and information compiled from different online sources, such as research articles and surveys found through Pubmed and Google Scholar. Research, surveys, and patients’ feedback highlighted that treatment barriers are primarily due to high financial costs for care, stigma surrounding recovery, bias against minorities, inconsistent treatment, and insufficient outpatient care. Furthermore, from a medical standpoint, primary care physicians only have surface level knowledge on how to provide treatment to patients but end up having to do so because there are a limited number of eating disorder specialists. If patients are diagnosed and given adequate care in the beginning stages and throughout their eating disorders, then not only will they be more likely to avoid falling into critical mental and physical conditions, but they will likely reach the point of recovery quicker and more efficiently.
Mechanical Design in Modular Reconfigurable Robotics: A Literature Review
This paper reviews recent research on mechanical aspects of modular reconfigurable robots (MRRs). Many newer MRRs have developed unique designs and hardware updated from the older, basic designs. The author compiled research of recent innovations in MRRs to include in the contents of this paper. The paper will first begin with reviewing the background of the MMRs and the influences it took on to create it. MMRs were inspired by the idea of one joining together with others to achieve a task not possible for a single individual. Based on this idea, MMRs have modules that form different structures by attaching to one another in different positions. With these unique differences to other robotics, the paper then discusses the numerous benefits MRRs brings to the table compared to traditional robots. The discussion of MRRs’ benefits also goes into territory of applications in space as MRRs could be used for in extraterrestrial expansion. Further in this paper, reoccurring designs of MRRs are analyzed, comparing older designs to recent ones. Here, the paper goes over recent MRRs and review their designs and mechanisms in depth, breaking down how they are built and how they work. The paper then examines the sensing in MRRs and recent innovations in making modules more aware of their surroundings. The differences between old and recent for both internal and external sensing used in modules will also be discussed and covered. Throughout this paper, the discussions of the similarity and lack of change/innovation from old MMRs to recent MRRs will be covered. Then finally, the paper will conclude with key findings determined by the author and what further research needs to be done on the topic.
How Can We Accelerate the Early Identification of Biomarker
Glycoprotein NMB for The Early Detection of Breast Cancer
The current methods for screening for any type of breast cancer involve the use of radiation levels or some form of waves. Widely used methods are CT scans, mammograms, MRIs, and ultrasounds, majority requiring the use of harmful radiation. A mammogram uses low energy x-rays to examine the human breast, a CT scan involves the usage of ionizing radiation, and an ultrasound transmits sound waves into the body. By identifying specific biomarkers like Glycoprotein NMB which are overexpressed in conditions like TNBC, we can find a more efficient and less harmful method of diagnosis. Usage and identification of these biomarkers to diagnose TNBC would also help with quicker and earlier detection compared to existing screening measures. The results of clinical trials experimenting with Glycoprotein NMB and various cancers point in a positive direction.

The study aims to evaluate the effect of coating seeds with micronutrients in combination with bacterial consortia on stomatal conductance and yields of cluster bean. Greenhouse experiments were carried out during August – December 2021 at Prayoga Institute of Education Research, Bangalore, India. The experiment consisted of 8 different treatments laid out in a randomized block design with five replications. Plant growth-promoting rhizobacteria (PGPR) are known to influence plant growth by various direct or indirect mechanisms. In search of efficient PGPR strains with multiple activities, a total of 10 bacterial strains were isolated from different rhizosphere soil and plant root nodules in the vicinity of Prayoga campus. These test isolates were screened in vitro for their plant growth-promoting traits like the production of Indoleacetic acid, production of Ammonia and Phosphate solubilization and three isolates were selected to develop consortia in different combinations. The micronutrients and bacterial consortia were applied to the seeds in combination as per the studied treatments and drought stress was created during growth stage. The study result revealed improved yields with a decrease in stomatal conductance due to plant adaptation to the stress induced by drought. There was a significant difference in the seed yield of treated treatments with that of the untreated control. Stomatal conductance (mmol m−2 s−1) of five randomly tagged plants was recorded by using a leaf porometer after 40 days and seed yield was recorded. Hence, coating seeds with bacterial consortia and micronutrients had a significant influence on the stomatal conductance and seed yield of cluster bean and this approach can serve as an effective strategy to enhance cluster bean crop performance.
An AI-Powered Assistive Device for the Visually Impaired
Global studies report that 253 million people suffer from visual impairment. Most rely on traditional aids including Braille, white canes and guide dogs which lack versatility and adaptability. This study intended to utilize A.I. text, object recognition models and ultrasonic technology to create an effective vision aid. The prototype was constructed using a Raspberry Pi board with a Pi camera, ultrasonic sensor, earbuds, and other peripherals. Text and object recognition algorithms were implemented to convert printed text and real objects captured by the camera’s live video feed to text output. Then, the text-to-speech code programmed in the device helped convert its text output to speech that could be heard through earbuds. Additionally, the ultrasonic sensors were programmed to determine the distance to the objects by measuring the time between emitting and receiving the reflected ultrasonic waves. During testing, the system recognized all sample words in 2.5 seconds on average and sample sentences in 6.4 seconds with 100% accuracy. Additionally, the device took 2.9 seconds on average to detect 80% of tested objects accurately and could detect large objects such as cars as far as 584cm away. The functional testing indicated that the prototype could inform users of recognized words and sentences, the types of detected objects, and their distance through audio. Thus, the results support the hypothesis that an AI-powered electronic device has the potential to provide reliable visual assistance to the visually impaired in their daily life.
Mechanics of HTLV - 1 Driven ATL
HTLV-1 (Human T-lymphotropic virus 1) is a retrovirus that can lead to the development of Adult T-cell leukemia/lymphoma (ATL), a non-Hodgkin's lymphoma, after a long latency period. Despite its low incidence rate, ATL is difficult to treat and has a poor prognosis with a median survival rate of 8 months and a 4-year survival rate of 12%. Recent research has suggested that ATL is host-driven, with low genetic diversity across endemic regions, challenging the previous assumption that ATL is solely caused by viral proteins. Blood sample studies from infected patients have revealed low genetic diversity, indicating the involvement of host genetic factors in ATL development. Host cancer genetic markers have also been found near the integration sites of the viral genome. This review highlights the correlation between patient genetics and HTLV-1 driven ATL, and how understanding the role of genetic markers and genes can lead to the development of new treatments or vaccines to improve patient outcomes.
A Study on the Effects of Physical Appearance on Psychological Status
and Cosmetic Surgery Preference: Differences by Generation
Physical appearance is not only a factor that influences an individual’s attractiveness, but it can also have an impact on one’s psychological status. In order to determine the correlation between one’s physical appearance and self- esteem, a survey on participants of different genders and various generations was conducted. The questionnaire consisted of a Rosenberg self-esteem scale (RSE) and 14 additional items related to respondents’ self-perception, social perceptions towards appearance, personal experiences of cosmetic surgery, and viewpoints on cosmetic surgery. Correlation analysis showed that the responses of each section of the questionnaire indeed had a significant correlation, meaning that the respondent’s physical attractiveness, self-esteem, and thoughts on plastic surgery were associated. Through gender-specific and age-specific analysis, the results of different participant groups were compared. Results indicated that generally, the older age group exhibited a weaker correlation between their appearance and self-esteem compared to the younger age groups. This phenomenon was discussed in detail and possible explanations for this phenomenon were presented. First, a tendency of older generations to prioritize values other than superficial standards was explained. When forming a self-perception, they were more likely to have standards such as social success and wealth rather than only physical attractiveness. Secondly, a possibility of the decline of cognition and perception caused by brain aging was suggested as a reason for the elderly to be less sensitive about their appearance compared to younger individuals.
Development of a Conceptual Design for a Future Mars Rover Mission
Mars is a widely unexplored planet with few rovers able to gather data on Mars. To hasten the progress of interplanetary research, we as humans need to develop the technology to explore other planets. The current solution is to send vehicles to planets such as Mars. Space Agencies such as NASA have been sending rovers and landers to mars for years. The scientists' effort has brought forth a lot of data about the red planet, and without them, these results could not be possible, and more innovation is needed to continue. Rovers are very complex but can simplify tools within subsystems within the entire rover system. It's detrimental to the function of the rover that every tool performs perfectly. With the development of a conceptual design for this rover, we could significantly decrease the time it would take to uncover the mysteries of Mars. In this paper, I researched details about previous rover missions to figure out a new plan to send a rover to mars. This outline includes the rocket for taking the rover to mars, the landing sequence, the landing location, the path the rover should take, and a basic understanding of what the rover would include and how it would appear. In addition to finalizing a landing location and identifying all working systems, the rover design (shown in the figures below) passed the computational tests with minimal stresses when applied when simulating forces present on Mars.
The Emergence of Losers in the South African Economy as a Result of Trade Liberalization
Trade liberalization is the process of reducing government-imposed restrictions on international trade. In South Africa, trade liberalization has been a key aspect of economic policy since the end of Apartheid in the 1900s. The nation has sought to increase its competitiveness by removing trade barriers, implementing more liberal trade policy frameworks, and anticipating the demands of South Africans for foreign goods and of foreign countries for South African goods. The results of trade liberalization have been mixed, with some industries benefiting greatly from this liberalization while others have struggled due to a lack of government support. Despite these challenges, South Africa continues to pursue business that its natural reserves and technological advancements can accommodate and is experiencing rising demand. This paper analyzes the mining, vehicle manufacturing, and agricultural industries in South Africa. Recent policy actions and trade transactions demonstrate that all three industries are experiencing growth. However, too much liberalization (lack of government support) is posing a threat to the extraction of certain precious metals, while the inconsistent distribution of foreign investment in vehicle manufacturing is causing the emergence of losers among a small number of small and medium-sized enterprises (SMEs).
The Relationship Between Maternal Immune Activation and Autism Spectrum Disorder
Maternal immune activation (MIA) has been linked to higher incidence of autism spectrum disorder (ASD). As maternal inflammation has been associated with viral infection and environmental stressors, much research has been dedicated to studying these connections. However, even with the research dedicated to understanding the links between MIA and ASD, how inflammation causes ASD remains unclear. This review aims to summarize the research focused on understanding the links between autism and maternal inflammation during pregnancy. We will focus on defining maternal immune inflammation, understanding how it develops, and how it can lead to ASD. Finally, we will explore new research objectives for prevention and therapeutic intervention in MIA induced ASD. Bringing these ideas into a central article will highlight common themes in MIA/ASD research as well as bring new experimental avenues to the forefront of researcher’s minds.
Scaling an Ensemble ML Algorithm for the Classification of
Tree Species Through Satellite Imagery
Dry conditions in the Western United States have increased the frequency and severity of forest fires in the Sierra Nevada Mountain Range. Organizations and cities are actively working towards developing a better understanding of forest structure and dynamics. While tree species classification models in the past have dealt with smaller regions and fewer trees, we hypothesized that it is possible to scale the area and number of trees analyzed by our model without sacrificing model accuracy by adding additional variables to satellite imagery, such as Normalized Difference Vegetation Index (NDVI), Normalized Difference Moisture Index (NDMI), Soil-Adjusted Vegetation Index (SAVI), crown ratio, tree height, and tree diameter. We compared the results of applying the Random Forest (RF) Machine Learning (ML) algorithm to a dataset containing satellite imagery alone and with a dataset containing satellite imagery augmented with object-specific attributes (OSA) such as crown shape, tree height, and tree diameter. We then trained and tested the algorithm across two large and different regions with similar tree species prevalence. After the addition of OSA to training data, the results from the experiment demonstrated a mean classification accuracy increase from 66.4% to 90.2%, thus allowing the ML model to scale over larger regions.
Lupus and Multiple Sclerosis: Understanding the Pathophysiology of Under- Funded Autoimmune Diseases and Potential Treatments
Published in June 2023

The immune system is a body system made up of cells, organs, and proteins that work together to defend the body against foreign invaders. However, there are times when the immune system attacks and kills its healthy tissue and cells, a condition known as autoimmunity. An autoimmune disease occurs when the immune system doesn’t know the difference between the body’s cells and foreign pathogens, so it attacks its cells. This paper will examine two autoimmune diseases: Lupus and Multiple Sclerosis (MS). Lupus is a chronic autoimmune disease that is often separated into five types. Lupus is mostly characterized by the inflammation it causes throughout the body, including a noticeable facial butterfly rash. Over 5 million people are affected by Lupus and there is no cure for Lupus, but trials have had varying results depending on the severity of the disease, with some treatments including NSAIDs inhibitors. MS is a chronic autoimmune disease characterized by fatigue, impaired vision, and tremors. MS is caused when the immune system destroys the protective sheath of nerve fibers, disrupting the flow of information in the nervous system, and causing nerve damage. There are about 2.3 million people diagnosed with MS. As of 2022, Lupus received over $139 million in funds while MS received over $20 million. Although MS and Lupus are both autoimmune diseases that affect a significant population, they do not receive nearly as much funding when compared to diseases like Cancer or Parkinson’s. This paper is dedicated to increasing awareness of the widespread effects of autoimmune diseases and the need for more funding. We have compiled background information and statistics using credible search engines and peer-reviewed studies for collective understanding.
Elucidating the Epigenetic Mechanisms that Modulate Biological Age
In recent years, changes in the epigenome have emerged as a key component in the aging process. DNA methylation, histone acetylation and methylation, and chromatin landscape remodeling are the most well researched of the types of epigenetic modifications. To best elucidate their functions, they should be understood as interacting parts in the context of an integrated epigenetic approach and not as exclusive mechanisms. Each type of modification undergoes some predictable changes with aging but may display variation depending on the individual, cell type, or organism. These epigenetic modifications correlate to changes in phenotypes common with aging and to increased susceptibility to age-related diseases, such as cancer or Alzheimer’s Disease. While age may cause these changes, epigenetic modifications also contribute to aging by altering gene expression and interacting with other agents of aging to further the progression. Therefore, the scope of this review looks at epigenetic modifications as an effect and driver of aging.
Developments and Challenges with Earthquake Detection, Prediction and Protection
Earthquakes have influenced life on Earth since civilization began. With urbanization and increased population densities across the globe, earthquakes pose a high threat to life and infrastructure alike. Although as a society, we have not yet developed a consistent method of earthquake prediction, developing technologies that are fundamentally based on different fields should allow us to attack this problem from multiple fronts. Research into the rapidly growing field of geosciences, specifically geophysics, is more important now than ever. In this review, the history of humanity’s documentation of earthquakes is explored, such as early earthquake quantification methods and seismograph development. Currrent detection methods and data analysis research into earthquake modeling are also reviewed here as they are currently our only means of prediction, and reveal the hopeful directions improved prediction in the future. Lastly, an interesting branch of earthquake prediction is explored, which involves animal behavior and the corresponding electric field phenomena correlated with earthquakes.
On the Normality of the Distribution of Colors of m&m Candy
This investigation explores the shape of the distributions of colors of m&m candy. Statistical tests: kurtosis, skewness, and Shapiro-Wilk were used to assess normality of the distribution of the colors. Kurtosis measures “peakedness” and skewness measures distortion of a distribution. The Shapiro-Wilk test outputs a categorical yes/no, to indicate normality. Distributions of colors were also visually assessed for normality through histograms. This investigation also considers how normality varies based on sample size and different samples of the same size. It was hypothesized that if m&m candy colors are randomly allocated to packets, with an adequately large sample size, they would follow a normal distribution (skewness =0, kurtosis = 3, Shapiro-Wilk test result = yes). The results support that increasing sample size does not make kurtosis and skewness closer to normally distributed with small samples (n<50). Also, there is evidence that normality varies within samples of the same size, based on skewness/kurtosis. Finally, approximate probability density functions (PDFs) were created for each color distribution. With the functions, probabilities of getting a certain number of candies of a given color were calculated. Based on the PDFs, it was found that the probability of getting a packet with only blue m&ms is higher than that of a packet with only red m&ms, though both are highly unlikely. There are certain limitations related to this investigation. It is possible due to the small group sizes that the kurtosis/skewness values did not approach normality. Experimentation with larger sample sizes (group size > 100 each) would facilitate more accurate estimation of probabilities.
Influence of pH on Coordination Reactions of Humic Acid with Metal Ions
The coordination reactions of Humic acid with metal ions were studied. Using the ion exchange equilibrium method, we can find the stability constants of complexes (log K) and the coordination number (x) of these reactions. The results showed that in the reactions of HA-Fe(3+), HA-Zn(2+), and HA-Cd(2+), the stability constants of complexes and coordination numbers increased as the pH increased and when ionic strength and temperature conditions were kept the same. For the reaction of HA-Mn(2+), the stability constants of complexes increased as the pH increased, and the coordination number increased as the pH increased during the range of 3.0 to 5.0; however, it decreased when the pH was increased from 5.0 to 7.0.
Generalized Anxiety Disorder and Sleep Quality during the COVID-19 Outbreak
in Adolescents & Parents: A Web-Based Cross-Sectional Survey
Many previous studies have shown that one’s anxiety is often heightened during disease pandemics. The present study found evidence that essential workers and their families are at an increased risk for anxiety, stress and sleep disruption. 160 female adolescents and 75 of their parents completed surveys measuring anxiety and sleep quality during the COVID-19 pandemic. The two samples, although drawn from the same community, were not linked. All adolescents attend an all-girls academy in suburban New York. T-tests and regression analyses suggest that essential workers and their families are at elevated risk for mental illness.
Code-switching: An Analysis of Causes, Benefits, and Perceptions
Code-switching is the linguistic phenomenon of alternating between two languages or dialects during a conversation. This paper explores the various factors that influence the practice of code-switching, focusing on those that are sociolinguistic, conversational, or a combination of both. By examining these factors, this paper aims to shed light on the complexities of code-switching and how it reflects larger societal attitudes toward language and identity. Through these factors, the paper sets to prove that code-switching is natural and predictable, making it something not to be discouraged or looked down upon as many teachers or parents believe. As such, this paper also addresses the issue of prescription versus description in code-switching research, arguing that linguists should adopt a descriptive approach to language, rather than a prescriptive one.

Hawthorne Christian Academy, Hawthorne, NJ USA
In spite of strides made in the field of medicine in relation to diabetes, there still remains a prominent percentage of people in the world who suffer from either Obesity or Type 2 Diabetes. Presently, there is no cure for these diseases, and the need for change is clear; therefore, medicine that can help curb the numbers of both diseases is crucial. Fortunately, Semaglutide is a new breakthrough in weight loss medication and has potential to treat Type 2 Diabetes patients as well. This paper aims to explain in depth the history of weight loss treatments, diabetes treatments, and the mechanisms of insulin and Semaglutide. Furthermore, to put this treatment in context, this paper dives deeply into the subtopics of continuous glucose monitoring, glucose management, current insulin research, and present treatment and preventative measures for diabetes today. Drawing from an array of studies, statistics, and scholarly articles, this paper shows the relevance of Semaglutide in a world with rising Obesity and Type 2 Diabetes, and the possible contributions it could have to these widespread diseases. Further research studies and analysis are being conducted daily in hopes of solidifying these first steps towards a cure and prevention.
LED Array Development: Highlights and Challenges of Red Light Therapy
Red light therapy (RLT) is a recent development that faces much uncertainty due to its novel nature. In essence, it has been found that the light photons trigger respiratory chain components which in turn activate a signaling cascade, and thus result in a cellular response. Some of these biological reactions aid in healing, skin repair, inflammation reduction, and functional improvement. Although such knowledge has been retained, scientists still struggle to understand how RLT truly works and the risks that are paired along. Though limited research has been conducted, this form of therapy allows for a wide variety of applications due to the numerous dosimetry parameters. As parameters have countless combinations, RLT can be used for people of varying ages, skin conditions, illnesses, and health backgrounds. Though seeming positive, such wide combinations leave room for the unpredictability of specific settings that pertain to each user. An additional concern is a basic accessibility; RLT has yet to be integrated into mainstream health improvement. In all, RLT provides optimistic solutions for high-performing humans, though much more research is required to uncover all the risks.
The Effects of Different Materials Used in Non-Aqueous Lithium Air
Battery Electrolytes on Ionic Conductivity and Durability
Batteries are increasingly important in moving away from fossil fuels towards a more sustainable future; they are currently used in many different applications, such as cars, portable electronics, and drones, but certain applications of batteries, such as in large aircraft, are limited by their gravimetric energy density. While many high energy density batteries have been synthesized, most lack high durability and are unable to withstand many charge and discharge cycles without losing considerable energy storage capacity. For example, lithium air batteries have one of the highest gravimetric energy densities of any battery, but because lithium ions are not able to flow freely from the anode to the cathode and vice versa. This paper examines recent advancements in lithium air battery materials and explores any potential developments for lithium air battery viability. It also discusses the various issues that plague lithium air battery advancement, and its place in the future of green energy and a viable source of energy storage.

COVID-19 has become a global phenomenon and a top priority for the world, making vaccine implementation a key tool for countries to address the problem. Boost refers to one additional supplementary vaccination following the completion of two doses of the SARS-CoV-2 vaccine, resulting in more than a 10-fold increase in antibody levels. The SARS-CoV-2 vaccine can maintain human immunity to the virus after antibodies have waned for some time. This study conducted a survey of the prevalence of SARS-CoV-2 vaccination in Guangdong Province, investigating SARS-CoV-2 vaccination among students and some educators, knowledge of the vaccine, attitudes, and the status of booster needle vaccination. Excel and SPSS software were used to analyze 166 samples. Five hypotheses were tested according to the data analysis, which are about the vaccination situation of SARS- CoV-2 vaccine, the relationship between people's understanding of the vaccine and the vaccination rate, people's attitude and enthusiasm towards the vaccine and the side effects of the booster injection of SARS-CoV-2 vaccine. This survey suggests that Policy-influenced vaccination intentions, rather than personal knowledge and understanding of the vaccine, were more strongly associated with the vaccination rates. , providing better reference to other pandemic and to areas with low vaccination coverage.
Comprehensive Review on Atopic Dermatitis and Therapeutic Potentials
Atopic dermatitis (AD) is a type of a skin-related allergy that affects all demographics worldwide, but mostly common amongst the younger population. It is characterized by itchy, red, and swollen skin, and there is currently no cure available. Disease etiology largely arises due to a combination of genetics and environmental influences, coupled with other types of comorbidities such as asthma and hay fever disease. AD largely is associated with a compromised epithelial tissue layer, which leads to decreased water retention and facilitated entry of allergens into the body, which further exacerbates the pathophysiology of the disease. Mechanistically, the progression of AD can be attributed to the overall imbalance of Th1 and Th2 cells, which disturbs the homeostasis between pro- inflammatory and anti-inflammatory polarizations of innate and adaptive immunity. Therefore, most of the current medications that help ameliorate AD’s pathogenesis include drugs that inhibit Th2 differentiation and polarization by targeting the activity of IL-13 and IL-4, both of which are implicated in the production of Th2 cells that subsequently induce IgE-mediated allergic reactions. The purpose of this review article is to comprehensively explore the biology of AD, including risk factors, diagnosis, pathophysiology, and the current available treatments.

Nanotechnology has been a critical field of study through its integration of many appliances. With public trust conflicting with the acceptance of nanotechnology, researchers have established that certain variables - such as prior knowledge of nanotechnology, religion, and religiosity - play a significant role in shaping people’s ethical perceptions of nanotechnology and, eventually, their public opinions. Therefore, this study focuses on finding and building the relationships between knowledge, religion, religiosity, and ethical concern of nanotechnology among teenagers in Granada Hills, California, to understand the influence of these variables on student perceptions of nanotechnology. A correlational study using quantitative data including a demographic survey, a 15-question Centrality of Religiosity Scale, prior knowledge evaluation, and an ethical concern section was administered to high school students from two schools in Granada Hills. Pearson product-moment correlations, ANOVA, and descriptive statistics were used to analyze the data. The results depicted that there was a negative relationship between knowledge and mean ethical concern, a negative relationship between knowledge and mean religiosity, a positive relationship between mean religiosity and mean ethical concern, and a positive correlation between age and mean knowledge of nanotechnology, all with weak coefficients. Ethical concerns were also explored, and students were found to be the most concerned about nanotechnology getting in the “wrong hands” and the loss of freedom and privacy. Additional research should be conducted on greater populations that consider different sociodemographic, affective, sociodemographic, or cognitive variables.

More than a third of the world’s population lives in countries that use more than 40% of their available supply of freshwater each year, an unsustainable level of demand. Most such countries have access to a sustainable water resource: seawater. However, desalination is currently too expensive for many of the communities that need it most. This paper presents a new desalination method: solvent-based liquid-liquid extraction that exploits the selective solubility of freshwater over saltwater in a particular class of polar organic solvents at certain temperatures below 100°C. For once such solvent, N-cyclohexyl pyrrolidone, the calculated desalination efficiency at 3 hours was 99.6%. Optional purification with a standard material yielded acceptably pure water. The method holds promise for development as a simple, low-energy, low-cost, low-waste process that can make desalination feasible in a broader range of coastal and marine applications.

Crows are an enigma to the world of biology—still under-researched and the extent of their cognitive abilities remains unknown. Throughout millennia, crows have influenced human cultures, including artwork, literature, poetry, and language. From reverence to repulsion, human perceptions of crows have evolved throughout history. As a recurring avian symbol in human society, our goal was to summarize recent and historical research on the complex and intricate minds of crows and ravens, while creating artwork in response to our work. In addition, we wanted to inform the public of crows’ ecological importance and presence in urban environments. This manuscript synthesizes recent scientific discoveries of crows and ravens and includes our original artwork as figures. Exploring crow behavior and biology, this review paper is organized into five thematic sections characterizing the life of a crow—neuroscience, communication, learning, urban habitat, and interactions with humans.
The Unknown Death Toll of COVID-19:
How The Pandemic Killed One Million Americans Long Before 2022
In this paper, I intend to convince the reader that the actual number of deaths caused both directly and indirectly by the COVID-19 pandemic in the United States of America has been much more than officially reported. According to an excess death regression model which accounts for circumstantial and unreported COVID deaths, there are approximately 130,000 additional pandemic-related deaths in 2020 and 140,000 in 2021. Adding the officially reported 831,000 COVID deaths in these two years, the pandemic may have caused over 1 million deaths much sooner than the officially reported date, May 24th, 2022.

Over the past two decades, dendrimers have emerged as a novel class of nanoparticles for cancer therapy and detection. They come in many varieties and are used to carry molecules like drugs or to act as imaging agents. They are composed of branches radiating out from a core, holding drugs between their branches or at the ends of them. Dendrimers are useful because of their customizability. They can be used for actively delivering drugs to tumors or for detecting cancer. Dendrimers have various traits that make them good for drug delivery, including their stability, water solubility, and uniformity. However, dendrimers also have limitations, displaying toxicity, or noting accumulate enough in the intended areas, and their interactions with the body are little known. Therefore, modifications to dendrimer structures are underway to solve some of the issues that their use presents. Overall, dendrimers show great potential in cancer therapy, but additional work needs to be done to enhance their specificity and effectiveness. They are important in the design of personalized cancer therapies, which we believe are the future of effective cancer treatment.

The limitations of drug discovery are infamous, with a single drug development setting back an institution millions of dollars and decades of time with only a 0.1% rate of success. Novel identification of target leads for drugs through currently unused epigenetic measures reduces these hurdles, incredibly expediting the drug pipeline. Here we identified two novel approaches for reducing liver cancer. In the first approach, this project focuses on reducing the hypermethylation of 5-methylcytosine (5mC) by modulating the 5-hydroxymethylcytosine (5hmC) biological pathway. Using pattern search and similarity indexes, Algorithm-1 can identify potential positions of pathway induction by comparing aberrant sequences with normal sequences and using a CpG island pattern trigger. Algorithm-1 identified the TP53 liver cancer gene at positions 33-35. In the second approach, this project focuses on inhibiting spliceosome factors that are responsible for 5mC production. Using machine learning methods and pattern search, such spliceosome factors are identified. Algorithm-2 identified the Prp9 protein. Both the proposed solutions provide new insight into a cure for Liver Cancer never previously explored through traditional methods of drug discovery.
The Effects of Colored Surgical Masks on Emotion Recognition
and Perception in Adolescents
Since the start of the COVID-19 pandemic, many studies have explored the effects of face masks on emotion recognition, yet no studies were conducted to explore the effect of different colored face masks on emotion recognition. This paper investigated the effect of four colors: red, black, green, and blue, compared to white, on perception of emotional intensity and recognition accuracy. 34 high schoolers were tested through a survey consisting of 120 images of models wearing surgical masks with photoshopped color stimuli. A significant effect was found in the colors red and green. Red enhances the perceived emotional intensity, and green confuses people into thinking the expression is disgust.

While there have been decades of research looking into the causes of Alzheimer’s disease (AD), the true underlying pathogenesis continues to be a focus of active mechanistic studies. Even so, there is little holistic understanding of what processes or therapies help alleviate the decline of memory and cognition. As a result, it is difficult for caregivers and healthcare providers to have tangible actions to focus on that are validated to maintain or improve an Alzheimer’s patient’s function and quality of life. Here, we present a literature review of the currently available research to examine which social and physiological factors, such as music, exercise, diet, and more, affect the disease progression and, of those, which slow it. We then summarize the currently available treatment options for Alzheimer’s dementia based on the previous findings. For example, melatonin improves disrupted circadian rhythms, while aerobic exercise and Mediterranean diets give neurons protection against beta-amyloid dysfunction through increased brain derived neurotrophic factor (BDNF). Additionally, SSRI drugs can help maintain brain mass while music therapy can temporarily activate preserved brain regions that enable positive moods.
Breakthroughs in Honey Bee Health, Continuous-Release Mist Diffusion
of Thymol-Based Essential Oils: Part II - The Field Study
Published in February 2023

Honey bees (Apis mellifera) are pivotal pollinators in agricultural and natural ecosystems; however, since the winter of 2006-2007, honey bee colonies have been disappearing. The greatest single contributor to the decline of honey bee health is the Varroa mite. Synthetic chemicals are used to control Varroa, but the mites are developing resistance. Essential oils (EO) may be a viable alternative. EO are cheaper, environmentally-friendly, pose fewer health risks to bees and consumers, and Varroa have not developed resistance to the oils. Currently, all commercially available thymol-centered systems are gel-based and work by direct contact with the mite. These systems are also highly dependent on temperature and humidity for effectiveness. Following the laboratory investigation (Part I), this field study (Part II) examined the use of thymol-based EO for miticide efficacy as well as the use of mist diffusers to eliminate any dependence of the essential oils on temperature and humidity conditions. Miticide efficacy was recorded as: thyme>oregano>rosemary>control (vegetable glycerin). Across all tested EO, the highest miticide activity occurred during the first two weeks of treatment. A brief cost analysis demonstrated using mist diffusers was more cost-effective than commercially available thymol-based systems (US$3.20 versus US$15-$18 per application). Continuous-release mist diffusion permits the disbursement of EO throughout the entire hive and effectively provided early elimination of mites as they emerged from the brood cell, while remaining safe for honey bees.
Mutation Pathogenicity and the Viability of HSP Therapy
for Mutated HEX-A in Tay-Sachs Disease
Published in January 2023

This work explored three different concepts. First, docking studies were performed with various mutant HexA structures and Arimoclomol (a Heat Shock Protein inducer), with statistical analysis to establish any correlation between noted binding affinity and either mutation pathogenicity or mutation type. This was followed by the review of Arimoclomol and Heat Shock Therapy as a potential therapeutic option for Tay Sachs disease, exploring the possibility for a future clinical trial. Finally, a gene mutation pathogenicity prediction model was developed using classification with the available dataset of HEXA gene mutations to experimentally determine the pathogenicity of any HEXA mutation. The statistical analysis found no correlations between either the mutation type or mutation pathogenicity and binding affinity. This leads to the conclusion that amino acid alterations don’t play a role in causing pathogenicity and benignity in a mutation and that the mutation type doesn’t affect the strength of interaction between a potential treatment and the mutant protein. The mutation pathogenicity prediction model study indicated that due to the lack of sufficient features and further compounded by the low correlation between the few features, the accuracy of the resulting model was not very high. Additionally, Arimoclomol was recommended for a clinical trial with Tay Sachs Disease.
Effect and Significance of Temperature on the Speed of Electromagnetic Waves

This project investigates the effect of temperature on the speed of electromagnetic wave when passing through water. In this experiment, a laser beam is fired through a semi-circular refraction dish containing water at an angle where the beam total internally reflected. After measuring the critical angle, calculations were made to derive the refractive index of water and ultimately the laser speed. The refractive index of water and hence speed of electromagnetic wave could be calculated. At the end of the investigation, there are no observable changes in the critical angle. Further research revealed that as the temperature increases, the speed of electromagnetic wave increases. However this change is negligible as the temperature range investigated is narrow. This effect’s cause is a slight decrease in liquid density, which decreases the refractive index of water when it is heated as a result.
Vagus Nerve Stimulation and Right Median Nerve Stimulation in the Treatment of
Coma: A Review of Previous Studies, Mechanisms of Action, and Future Potentials
Published in January 2023

Lowell High School, San Francisco, CA USA
Disorders of consciousness affect a large percentage of patients with brain trauma, and diagnosed patients face a high mortality rate. Recently though, two types of nerve stimulation have proved promising effects: vagus and right median nerve stimulation. Because of their extensive projections throughout the regions of the brain responsible for consciousness, the vagus and right median nerves have been targeted for studies of nerve stimulation in the treatment of coma and have proven effective in improving the states of consciousness in comatose patients. Although complete mechanisms are still unknown, many studies have corroborated the idea that delivering electrical pulses through such stimulation can elevate levels of brain activity in the stagnant coma-state brain, especially in sleep-wake cycle related brain regions such as the reticular activating system, locus coeruleus, parietal cortex, and thalamus. By activating the neurons in these parts of the brain, neural pathways — noradrenergic, cholinergic, GABAergic, dopaminergic, and orexin pathways — are enhanced. These pathways have shown to interact with each other in a complex manner still not yet thoroughly explored, but have proven to collectively increase arousal in coma patients. Furthermore, nerve stimulation seems to have positive effects on the physiological healing of the brain from traumatic brain injury, one of the root causes of coma, through increasing cerebral blood flow. Taken together, these studies point towards right median and vagus nerve stimulation as a promising treatment that can help better the outcome of coma.
Novel Therapies in the Treatment of Parkinson’s Disease
Published in January 2023

Parkinson’s Disease (PD) is the second most common neurodegenerative disease, caused by the degenerative progression of dopaminergic neurons located in the substantia nigra pars compacta, which results in the decreased production of dopamine — a necessary neurotransmitter to maintain homeostasis. However, the ultimate cause of damage done to these neurotransmitters is unknown, as it has been found that the development of Lewy Bodies, overproduction of calcium ions, and other protein mutations can all cause dopaminergic neurons to be deficient. The development of PD causes deteriorating symptoms such as bradykinesia, motor tremors, muscle stiffness, and impaired balance. No cure for Parkinson’s disease has been developed, in which researchers have instead developed therapies to combat the degenerative symptoms that result from PD. Recently, there has been an amplification in research and generation of medical pharmacologic therapies and invasive surgical therapies, such as Deep Brain Stimulation, to alleviate symptoms. Although current pharmacologic therapies function to a certain degree, they are not effective over long periods, which is how PD becomes increasingly damaging. Similarly, there is a lack of definitive disease-modifying therapies such as alpha-synuclein antibodies, LRRK2 antibodies, exenatide, and isradipine. These disease-modifying pharmaceuticals, surgical therapies, and future treatments must continue to be researched for safety, longevity, and effectiveness to promote optimal quality of PD patients.
Through the One-Sided Mirror: Effects of Commodification on an
Individual's Cultural Perception
Earlier literature and research have examined cross-cultural differences in cognition and behavior across a multitude of fields, spanning sociology, business, and psychology. The scope of such research on cultures has mainly focused on describing the culture, or the individual as part of that culture; in comparison, there has been little investigation of the effects of cultural interactions. Research thus far has investigated subjects such as consumer cultural reactance, as well as responses to cultural identity threats. However, despite this literature, and research on the disparity between internal and external perceptions of self, little literature exists regarding how one views their cultures. Foreign audiences may see a culture different from the people who identify with that culture. This disparity may be further emphasized during cultural branding and marketing when only limited aspects of that culture may be emphasized for monetization. This paper aims to explore how these differences in cultural and self-perception affect one’s perception of their own culture and one’s behavior with respect to that change after the culture has undergone commodification and marketing to a foreign audience. We focus on the nuance within this and how the behaviors may change depending on whether the culture is individualist or collectivist, the level of identification to a culture, and the salience of monetary profit from commodification. Through this, we hope to utilize the literature on cultures, on self vs. other perceptions, and on the commodification of in-groups vs. out-groups to develop a framework for assessing identifier reactions to cultural commodification and intercultural interaction.
