Photogalvanic Shift Currents In Bifeo3-Lafeo3 Superlattices, Francesco Delodovici, Charles Paillard

Physics Faculty Publications and Presentations

Designing materials with a controlled photovoltaic response may lead to improved solar cells or photosensors. In this regard, ferroelectric superlattices have emerged as a rich platform to engineer functional properties. In addition, ferroelectrics are naturally endowed with a bulk photovoltaic response stemming from nonthermalized photoexcited carriers, which can overcome the fundamental limits of current solar cells. Yet, their photovoltaic output has been limited by poor optical absorption and poor charge collection or photoexcited carrier mean free path. We use Density Functional Theory and Wannierization to compute the so-called Bulk Photovoltaic shift current and the optical properties of BiFeO3/LaFeO3 superlattices. We …

From Λ-Hollow Frames To Λ-Repletions In W: Ii. Λ-Repletions In W, Richard N. Ball, Anthony W. Hager, Joanne Walters-Wayland

Mathematics, Physics, and Computer Science Faculty Articles and Research

In this article we analyze the fine structure of the essential extensions of an object of W, the category of divisible archimedean lattice ordered groups with designated weak units. In particular, we show that an object Ghas an ordinally indexed sequence {τ^α_G}_δG of essential extensions with the following features. τ⁰_G is (isomorphic to) the identity function on G.

• For every α>0, τ^α_G is an essential extension of G into a W-object which is of the form RLfor some frame L, and which is λ-replete for some λ.

• Every such …

Immuno-Bioinformatics Study Of Secondary Metabolites From Watercress Nasturtium Officinale As Immunostimulant In Whiteleg Shrimp Litopenaeus Vannamei By Targeting Peroxinectin And Scavenger Receptor Class B, Qurrota A’Yunin, Muhaimin Rifa’I, Maftuch Maftuch, Yoga Dwi Jatmiko, Muhammad Hermawan Widyananda, Triyanto Triyanto, Muhammad Tegar Handrianto

Karbala International Journal of Modern Science

The viral disease affects the whiteleg shrimp (Litopenaeus vannamei) and causes losses. Immunostimulants are recognized as a more environmentally friendly approach to disease management and antimicrobial properties of aquatic organisms. Watercress (Nasturtium officinale) is an aquatic plant species that contains antioxidant properties that can protect the organism from disease and boost the immune system. Shrimp rely heavily on innate immunity to combat infectious agents due to their absence of adaptive immunity. Peroxinectin and scavenger receptor class B (SRB) play essential roles in the shrimp defense system. This research employs a bioinformatic to assess the immunostimulatory potential …

Quantifying Dust Nutrient Mobility Through An Alpine Watershed, Jeffrey R. Nielson, Janice Brahney

Watershed Sciences Faculty Publications

Dust has the potential to play a significant role in the nutrient dynamics of alpine watersheds with important ecological implications. However, little is known about how dust nutrients circulate through the environment and which watershed characteristics facilitate dust impacts on water quality. This study explored the contribution of dust-deposited nutrients, focusing on a high-elevation Long Term Ecological Research site, where dust samples have been continuously collected since 2017. We incorporated observed dust nutrient compositions, including fractions of inorganic and organic nitrogen and phosphorus, into a popular hydrological model, the Soil and Water Assessment Tool, and ran simulations for 2019–2021.

Travel to and from distant cancer treatment facilities can place a significant burden on cancer patients, particularly rural and minority survivors. Thus, the purpose of our investigation was to examine the association between patient travel distance and delays in types of treatment for breast cancer (surgery, radiation, chemotherapy, and hormonal therapy) and treatment delays. Using a novel linkage between the state cancer registry and administrative data from Medicaid and a private insurance plan, 2155 BC patients were successfully linked to create the cohort. ArcGIS was used to geocode all case residences and treatment facility addresses and calculate network distance between …

Study On Ratio Of Cutting Height To Caving Height For Efficient Top-Coal Recovery In Extra Thick And Gently Inclined Coal Seam – A Case Study Of Seam 7 Ha Lam Coal Mine, Vietnam, Duc Hung Pham, Tien Dung Le, Phi Hung Nguyen, Van Quan Pham

Journal of Sustainable Mining

The mechanized longwall top-coal caving technology (LTCC) has been used in Quang Ninh underground coal mines owned by Vietnam National Coal – Mineral Industries Holding Corporation Limited (Vinacomin). The application of the LTCC technology has achieved significant achievements, contributing to the production of coal for national economy development. The use of LTCC has shown that the top-coal recovery efficiency is directly affected by the sequence of top coal drawing, ratio of cutting height to caving height, and caving span. These parameters, especially for extracting thick and gently inclined coal seam conditions as in the Quang Ninh coal field, have not …

Increasing Atmospheric Evaporative Demand Across The Tibetan Plateau And Implications For Surface Water Resources, Shiqin Xu, Dennis P. Lettenmaier, Tom R. Mcvicar, Pierre Gentine, Hylke E. Beck, Joshua B. Fisher, Zhongbo Yu, Ningpeng Dong, Akash Koppa, Matthew F. Mccabe

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

The Tibetan Plateau, known as the “Asian water tower,” is a hotspot for complex hydroclimatic changes. We reveal that the previously decreasing atmospheric evaporative demand (Eo) trend at the end of the 20th century has reversed over the last two decades. Although both wind stilling and solar dimming have persisted, their effects on Eo rates have been overshadowed by increasing air temperatures and decreasing relative humidity, leading to a net rise in Eo for 1980−2015. Using the empirical “top-down” Budyko approach, we estimate that across seven sub-catchments draining the Tibetan Plateau, a 10% increase in annual-averaged …

Comparison Of Two Strategies Of Screening Experiments: Single-Shot Experiment Vs. Two-Stage Screening Experiment, Kelvin Njuki, Emil Agbemade

Data Science and Data Mining

Experiments involving many factors are often complex, time-consuming, and expensive. Screening out the least important factors helps the experimenter(s) allocate the limited resources efciently to the most important factors. Supersaturated and orthogonal array designs are among the designs used to conduct screening experiments. Supersaturated designs (SSDs) are those where the number of runs (observations) is less than the number of factors, while orthogonal array (OA) designs are those where at least the columns are orthogonal to each other. In this study, we conduct a simulation study to compare two strategies of screening experiments. Strategy one is a single shot experiment …

Breaking Barriers: Investigating Gender Dynamics In Introductory Physics Lab Classes, Bilas Paul, Shantanu Chakraborty, Ganga Sharma

Georgia Journal of Science

The persistent underrepresentation of women and other gender minorities in physical science fields has been an ongoing concern. This study investigates gender dynamics in introductory physics laboratory courses, focusing on whether students of different gender identities exhibit equal inclination and confidence in conducting lab experiments, and whether they face barriers that impact their participation. Conducted across three institutions and involving non-physics STEM students enrolled in algebra-based and calculus-based physics courses, the study found mixed results, with two institutions showing no significant gender-based differences in participation levels during lab activities, while one institution demonstrated significant differences. Chi-square tests revealed no significant …

Pesticide Runoff From Conventional, Minimum, And No-Tillage Cropping Systems: Meta-Analysis Of Published North American Data, Daniel Fleming, Dave Spencer, Chicot Irrigation

WRRI Publications

Pesticide applications may soon be regulated by laws predicated on the presupposition that reducing tillage, and thereby increasing soil surface crop residue cover, decreases sorbed and soluble agrochemical losses in surface runoff and erosion. This analysis was conducted to determine whether pesticide transport via surface runoff and erosion could be manipulated by tillage practices. Estimates of the amounts of crop residue cover within each tillage practice were averaged from data reported in the original articles. Response ratios of the paired means of runoff, erosion, and pesticide losses and concentrations from the effects of tillage practices were meta-analyzed as paired t-tests …

The Strandja Mountains in the northwestern part of Turkey host porphyry and skarn type mineralizations and ancient slag heaps, which are the residues of ancient metallurgical processes. Ancient smelting furnaces were established near the skarn type mineralization zones and the ores were processed. Charcoal were used as fuel in these furnaces. Tenorite mineral was detected in the mineralogical analyses of the slags by XRD and it was determined that the furnaces were heated above 1000 °C. When the distribution of SiO2 in the slags was examined according to different end members, it was determined that the melting temperatures were in …

Playing The Digital Dialectic Game: Writing Pedagogy With Generative Ai, Rebekah Shultz Colby

University Writing Program: Faculty Scholarship

This article explores teaching writing with generative AI as critical play where students and teachers engage in an ethically dialectical and aleatory game with generative AI. I qualitatively surveyed 24 writing teachers about how they teach writing with generative AI as well as its advantages and disadvantages. I discovered that teachers used generative AI to teach about the ethics of generative AI's design and rhetorical use to avoid plagiarism. Teachers also critically played with generative AI to teach the writing process of invention, drafting, revision, and editing. Specifically, the critical, dialectical interplay of human and machine invents in aleatory and …

Ethnic Disparities In Hba1c And Hypoglycemia Among Youth With Type 1 Diabetes: Beyond Access To Technology, Social Deprivation And Mean Blood Glucose, J. Pemberton, Zhide Fang, Stuart Chalew, S. Uday

School of Public Health Faculty Publications

Introduction The UK national pediatric diabetes audit reports higher HbA1c for children and young people (CYP) with type 1 diabetes (T1D) of Black ethnicity compared with White counterparts. This is presumably related to higher mean blood glucose (MBG) due to lower socioeconomic status (SES) and less access to technology. We aimed to determine if HbA1c ethnic disparity persists after accounting for the above variables. Research design and methods A retrospective analysis of participants who received structured education in continuous glucose monitoring (CGM) use was conducted at a tertiary center. HbA1c was paired with glucose metrics from 90-day CGM data. The …

Geochronological And Isotopic Data From The Adakitic Dodurga Pluton (Central Pontides, N Türkiye): New Insights For The Geodynamic Evolution Of The Northern Neotethys, Okay Çi̇men, Mehmet Ali̇ Gücer, Antonio Simonetti, Fati̇h Karaoğlan

Turkish Journal of Earth Sciences

The Dodurga Pluton is located within the Central Pontides (northern Türkiye) and, has a SW-NE elongation, and consists of granodiorite and dacite porphyry. Previous studies have suggested that this pluton is Triassic in age, and its whole-rock geochemical systematics are consistent with those from adakitic magmatic occurrences rather than the classic arc granitoid suite. This study reports the first time in-situ/whole-rock radiogenic isotopic (Sr, Nd and Pb) and mica/amphibole Ar-Ar age data to evaluate better its petrogenetic-geodynamic evolution and chemical nature of mantle source(s). Unlike previous data, combined new in-situ zircon U-Pb yield Late Cretaceous crystallization ages of 84.2±0.9 Ma …
