Analysis of Tire Wear Airstrip Particles (TWAP)
Authors: Spanheimer Vanessa , Katrakova-Krüger Danka 
Published: June 2022

Abstract
Every aircraft leaves tire wear particles on the ground of airports at take-off and landing. To maintain good grip properties, the pavement must be regularly cleaned up. The gathered Tire Wear Airstrip Particles (TWAP) normally get disposed by burning. As they are very similar to rubber powder the question is if they might be used as a secondary raw material to keep them longer in the loop in the sense of circular economy. In this study TWAP gathered by the cleaning of the runway of an airport in Germany are compared to ambient ground rubber powder from truck tire treads. Both are analyzed microscopically with regard to their morphology, particle size distribution and chemical composition by calcination with following elemental characterization of the ash by Energy-Dispersion-X-ray Analysis (EDS) in the Scanning Electron Microscope (SEM) and Thermal Gravimetric Analysis (TGA). The particle size distribution of TWAP is broader than rubber powder containing also much smaller particles. The mineral content is about 60% of the gathered TWAP. These minerals can be residues of the pavement or break wear and to a smaller amount from the rubber ingredients. Although the TWAP on their own are similar to rubber powder, the impurities they contain may have an impact with regard to potential applications.

Abstract
To improve the electrical performance of power devices, materials used in fabrication need to be analyzed and optimized. By numerical simulations, we reveal that the breakdown voltage (BV) and location of a lateral diffused MOS power device simultaneously depend on trench oxide permittivity. For a given device geometry, while trench oxide permittivity with a certain value leads to a maximal BV, a smaller (larger) value causes electrical breakdown in the Si drift channel around the bottom (top) of the trench. This trend stays the same when Si is replaced by SiC. Our study implies that any byproduct reducing the trench permittivity during trench filling should be avoided.

Abstract
In this work, Hydrophilic Interaction Liquid Chromatography – Mass Spectrometry (HILIC-MS) was applied to assess the metabolic profiles of different tissues and industrially relevant co-products of alginate extraction from Laminaria hyperborea samples obtained in different seasons. This is the first metabolomic analysis in L. hyperborea and it allowed the putative identification of 59 metabolites using positive and negative mode MS data, predicted exact mass data and matching with database and literature searches. Another 16 components were detected but these could not be identified as yet. The metabolites ranged from known and abundant components (e.g., iodide, mannitol and various betaines) to components not previously noted in this species. The levels of these components varied between tissues and co-products with some metabolites seemingly specific to certain samples. The components also varied between winter and summer samples, perhaps reflecting seasonality in their biosynthesis and accumulation in the tissues and co-products.Therefore, the method can be used to survey the seasonal metabolomic variation across the full year and thereby track when components of potential specific commercial interest were maximally accumulated and help plan the most efficient exploitation of the harvested biomass. The method could also define variation in components in L. hyperborea from different locations or potential biotopes of this species. This initial work extends our ability to understand the phenotype of seaweeds whilst also identifying new components and new commercial opportunities.
The Expression and Prognostic Value of CCL19 in Breast Cancer
Authors: Chen Xiao , Li Wanwan , Yang Lei , Zhang Jianzhong , Lei Xinhan , Tang Tong , Jia WenJun 
Published: June 2022

Abstract
Background
Breast cancer is the leading cause of cancer related death in women worldwide. Early diagnosis is the most effective way to reduce breast cancer mortality. Immune and tumor processes are closely related. This study aims to explore the mechanism of immune and potential biomarkers of breast cancer through bioinformatics.
Objective
First, differentially expressed genes (DEGs) were screened by consensus analysis of invasive breast cancer (BRCA) samples from The Cancer Genome Atlas (TCGA) database based on immune genes. Then, protein interaction (PPI) networks, Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) analyses were used to narrow down the potential genes. Finally, expression analysis and prognostic analysis of hub genes were used to select reliable key genes to identify CCL19. Immunohistochemistry (IHC) was used to detect the differential expression of CCL19 in tumor tissues and adjacent tissues of breast cancer. Protein correlation analysis, signaling pathway analysis, immune infiltration analysis, gene co-expression analysis and drug sensitivity analysis of CCL19 were further used to explore the pathological clinical features and potential biological functions of CCL19.
Results
The expression of CCL19 was significantly increased in breast cancer. High expression of CCL19 correlates with tumor stage and predicts a better prognosis in breast cancer. The expression of CCL19 correlates with the levels of various tumor immune infiltrating cells (TILs). CCL19 has positive correlation with the expression of most immune-related genes, including immune activator, immunosuppressant, chemokine, chemokine receptor, and major histocompatibility complex (MHC) genes. Enrichment analysis showed that CCL19 was involved in immune-related pathways and PI3K-Akt signaling pathway. The above results indicate that CCL19 may modulate the prognosis of breast cancer through immune infiltration. CCL19 affects the sensitivity to chemotherapy and targeted therapy, which affects the sensitivity of TAK-715, KIN001-102 and 17-AAG.
Conclusion
CCL19 is overexpressed in breast cancer. CCL19 may serve as a promising biomarker for predicting breast prognosis and a candidate therapeutic target.

Abstract
In 2020, Brazil was the seventh largest emitter of GHG (Greenhouse Gases), releasing ~ 2.16 GtCO2e (gigatons of carbon dioxide equivalent) into the atmosphere. Activities related to land use contributed to approximately 73% of national emissions in that year. Considering that pastures represent the primary land use in the country, the mapping and monitoring of C stocks in these areas are essential to determine their participation in national emissions. In this study, based on the integrated use of the Century model, georeferenced databases, and the R environment, we mapped and analyzed the C stocks dynamics in the pastures of the Cerrado biome between 2000 and 2019. The average C stocks in the soil (0–20 cm) and in the aboveground biomass estimated by modeling were ~ 31 MgC.ha− 1 and ~ 4 MgC.ha− 1, respectively, values close to those observed in the literature for the region. Furthermore, the model results corresponded to the edaphic patterns of the region, with the highest average estimated C stocks in Cambisols (~ 34 MgC.ha-1) and the lowest in Neosols (~ 29 MgC.ha-1). The temporal dynamics of soil C stocks in these areas are directly related to the age of the pastures, with a reduction in stocks from recently converted areas and stabilization in areas that have been under this land use for a longer time (≥ 30 years). As a result, a loss of ~ 103 MtC (Millions of tons of Carbon) was estimated in the Cerrado pasture soils in twenty years.The mapping and monitoring C stocks in this land use type through approaches such as the one presented in this study is essential to support the Brazilian Government's efforts to mitigate C emissions.

Abstract
Monitoring the quality of water ensures it is safe for life. Nowadays, its effectiveness requires embracing data science. This was done in the context of the Water and Sanitation Corporation (WASAC) of Rwanda, which manages 18 water treatment plants (WTPs). This research aims at monitoring the drinking water quality key performance indicators (KPIs) using an interactive dashboard that can map interventions, perform calculations, assess the performance, and provide near real-time information. A four-step approach—KPI identification, data collection, monitoring tools, and progress tracking—was used. Step 1 used the literature review to identify KPIs in terms of compliance with clean water regulatory and reliability requirements, and the existence of a functional system to address customer needs. Then, primary and secondary data sets, including Twitter data, were collected in step 2. The third step consisted of computing the drinking water quality index (DWQI), performance discrepancy scores (PDS), and Twitter sentiment scores, as well as an interactive dashboard. Finally, results were analyzed to determine WASAC's performance towards quality KPIs. Compliance with clean water requirements has been generally consistent, and the first five WTPs were Kadahokwa, Cyunyu, Mutobo, Muhazi, and Kimisagara. However, the water reliability could not be confirmed due to missing data. Twitter data analysis confirmed the existence of a system to address customer needs and to notify customers of planned rationing or interruptions of water supply. Therefore, the suitability of water for human consumption was generally established, but more efforts were recommended to ensure full and consistent compliance.

Abstract
Activity recognition is the process of continuously monitoring a person’s activity and movement. Human posture recognition can be utilized to assemble a self-guidance practice framework that permits individuals to learn and rehearse yoga postures accurately without help from anyone else. Using Deep learning algorithms, an approach has been taken to accurately detect and recognize various yoga poses. The chosen dataset consists of a total of 85 videos with 6 yoga postures performed by 15 participants. Initially, keypoints of the user are extracted using the Mediapipe library. A combination of convolutional neural network (CNN) and long short-term memory (LSTM) has been used for Yoga pose recognition through real-time monitored videos as a deep learning model. CNN layer is used for extraction of features from the keypoints and it is followed by LSTM that understands the occurrence of sequence of frames for predictions to be made. Then, the poses are classified as correct or incorrect. If a correct pose is identified, the system will give the user feedback through text/speech.

Gauging U(1) symmetry in (2+1)d topological phases
Authors: Cheng Meng , Jian Chao-Ming 
Published: June 2022

We study the gauging of a global U(1) symmetry in a gapped system in
(2+1)d. The gauging procedure has been well-understood for a finite
global symmetry group, which leads to a new gapped phase with emergent
gauge structure and can be described algebraically using the
mathematical framework of modular tensor category (MTC). We develop a
categorical description of U(1) gauging in a MTC, taking into account
the dynamics of U(1) gauge field absent in the finite group case. When
the ungauged system has a non-zero Hall conductance, the gauged theory
remains gapped and we determine the complete set of anyon data for the
gauged theory. On the other hand, when the Hall conductance vanishes, we
argue that gauging has the same effect of condensing a special Abelian
anyon nucleated by inserting 2\pi2π
U(1) flux. We apply our procedure to the
SU(2)_kk
MTCs and derive the full MTC data for the \mathbb{Z}_kℤk
parafermion MTCs. We also discuss a dual U(1) symmetry that emerges
after the original U(1) symmetry of an MTC is gauged.

An Innovative Use of Twitter to Disseminate and Promote Medical Student Scholarship During the COVID-19 Pandemic: Usability Study
Authors: Allen Gary , Garris Jenna , Lawson Luan , Reeder Timothy , Crotty Jennifer , Hannan Johanna , Brewer Kori 
Published: June 2022

Background
Due to the emergence of the COVID-19 pandemic in March 2020, the cancellation of in-person learning activities forced every aspect of medical education and student engagement to pivot to a web-based format, including activities supporting the performance and dissemination of scholarly work. At that time, social media had been used to augment in-person conference learning, but it had not been used as the sole platform for scholarly abstract presentations.

Objective
Our aim was to assess the feasibility of using Twitter to provide a completely web-based forum for real-time dissemination of and engagement with student scholarly work as an alternative to a traditional in-person poster presentation session.

Methods
The Brody School of Medicine at East Carolina University launched an online Medical Student Scholarship Forum, using Twitter as a platform for students to present scholarly work and prepare for future web-based presentations. A single student forum participant created posts using a standardized template that incorporated student research descriptions, uniform promotional hashtags, and individual poster presentations. Tweets were released over 5 days and analytic data were collected from the Twitter platform. Outcome measures included impressions, engagements, retweets, likes, media engagements, and average daily engagement rate.

Results
During the conference, the student leader published 63 tweets promoting the work of 58 students (55 medical and 3 dental students) over 5 days. During the forum and the following week, tweets from the @BrodyDistinctly Twitter account received 63,142 impressions and 7487 engagements, including 187 retweets, 1427 likes, and 2082 media engagements. During the 5 days of the forum, the average daily engagement rate was 12.72%.

Conclusions
Using Twitter as a means of scholarly dissemination resulted in a larger viewing community compared to a traditional in-person event. Early evidence suggests that social media platforms may be an alternative to traditional scholarly presentations. Presenting via Twitter allowed students to receive instantaneous feedback and effectively network with wider academic communities. Additional research is needed to evaluate the effectiveness of knowledge uptake, feedback, and networking.
The Impact of SARS-CoV-2 (COVID-19) on the Acuity of Mental Health–Related Diagnosis at Admission for Young Adults in New York City and Washington, DC: Observational Study
Authors: Fialk Amanda , Connors Alexa , Cerrito Brianna , Jones Karee , Buono Frank 
Published: June 2022

Background
The COVID-19 pandemic has required restrictive measures to mitigate transmission of the virus. Evidence has demonstrated increased generalized anxiety and depression among young adults due to the COVID-19 pandemic. However, minimal research has examined the longitudinal effect of COVID-19 over the course of time and its impact on anxiety and depression. Additionally, age and gender have been found to play a significant role on individuals’ mental health, with young adults and women particularly at risk.

Objective
The aim of this study was to examine the impact of the COVID-19 pandemic on anxiety and depression upon admissions to treatment.

Methods
This was an observational study that was completed longitudinally in which the grouping variable split the time interval into five equal groups for assessments over each period of time. A total of 112 young adults (aged 18-25 years) were recruited for the study. Participants completed assessments online through a Qualtrics link.

Results
Psychometric properties of the admission assessments were uniformly highly statistically significant. There was a significant difference in generalized anxiety between the group-1 and group-3 time intervals. No significant difference was found across the time intervals for depression. Differences in predicting the impact of the psychometrics scores were found with respect to gender. Only the ability to participate and the quality-of-life subfactor of the Functional Assessment of Chronic Illness Therapy (FACIT) assessment were significant.

Conclusions
This study sought to understand the impact that COVID-19 has had on young adults seeking mental health services during the pandemic. Gender emerged as a clear significant factor contributing to increased anxiety in young adults seeking mental health services during the pandemic. These findings have critical importance to ensuring the potential treatment success rate of clients, while providing an overarching understanding of the impact of the pandemic and establishing clinical recommendations for the treatment of individuals who are seeking out treatment.
