Clock Time Of First Eating Episode And Prospective Risk Of All-Cause Mortality In Us Adults, Ashima K. Kant, Barry I. Graubard

Publications and Research

Background: There is increasing recognition that morning or evening preference is associated with time of eating, metabolic health, and morbidity. However, few studies have examined the association of time of eating with mortality.

Objective: To examine the association of time of first recalled ingestive episode with prospective risk of all-cause mortality.

Design: We used mortality-linked data from the National Health and Nutrition Examination Surveys (NHANES) conducted in 1988-1994 and 1999-2014 (n=34609; age >40 y). Quartiles (Q1-Q4) of clock time of first eating episode self-reported in the baseline 24-h dietary recall was the exposure. Follow-up time from date of NHANES examination …

Electrocardiographic Changes In Emphysema, Puneet Gupta, Hitangee Jain, Misbah Gill, Gurpreet Bharaj, Nauman Khalid, Waseem Chaudhry, Lovely Chhabra

Publications and Research

Chronic obstructive lung disease (COPD), predominantly emphysema, causes several thoracic anatomical and hemodynamic changes which may cause changes in various electrocardiographic parameters. A 12-lead electrocardiogram (ECG), which is often a part of routine evaluation in most clinical settings, may serve as a useful screening modality for diagnosis of COPD or emphysema. Our current article aims to provide a comprehensive review of the electrocardiographic changes encountered in COPD/emphysema utilizing published PubMed and Medline literature database. Several important ECG changes are present in COPD/emphysema and may serve as a good diagnostic tool. Verticalization of Pvector, changes in QRS duration, pattern recognition of …

Identity Selection And The Social Construction Of Birthdays, Brett W. Pelham, Tracy Dehart, Mitsuru Shimizu, Curtis D. Hardin, H. Anna Han, William Von Hippel

Publications and Research

We argue that rather than being a wholly random event, birthdays are sometimes selected by parents. We further argue that such effects have changed over time and are the result of important psychological processes. Long ago, U.S. American parents greatly overclaimed holidays as their children’s birthdays. These effects were larger for more important holidays, and they grew smaller as births moved to hospitals and became officially documented. These effects were exaggerated for ethnic groups that deeply valued specific holidays. Parents also overclaimed well-liked calendar days and avoided disliked calendar days as their children’s birthdays. However, after birthday selection effects virtually …

Tailoring Plasmon Excitations In Alpha − T 3 Armchair Nanoribbons, Andrii Iurov, Liubov Zhemchuzhna, Godfrey Gumbs, Danhong Huang, Paula Fekete, Farhana Anwar, Dipendra Dahal, Nicholas Weekes

Publications and Research

We have calculated and investigated the electronic states, dynamical polarization function and the plasmon excitations for α − T ₃ nanoribbons with armchair-edge termination. The obtained plasmon dispersions are found to depend significantly on the number of atomic rows across the ribbon and the energy gap which is also determined by the nanoribbon geometry. The bandgap appears to have the strongest effect on both the plasmon dispersions and their Landau damping. We have determined the conditions when relative hopping parameter α of an α − T ₃ lattice has a strong effect on the plasmons which makes our material distinguished …

Graduate Student Employee Unionization In The Second Gilded Age, William A. Herbert, Joseph Van Der Naald

Publications and Research

In debates on the future of work, a common theme has been how work became
less secure through the denial of employee status. Though much of the attention
has focused on other industries, precarity has also affected those working in
higher education, including graduate student employees, contributing to what is
now called the “gig academy.” While universities have reassigned teaching and
research to graduate assistants, they have also refused to recognize them as
employees. Nevertheless, unionization has grown considerably since 2012, most
significantly at private institutions. Utilizing a unique dataset, this chapter
demonstrates that between 2012 and 2019, graduate student …

Regulatory Non-Coding Rnas Modulate Transcriptional Activation During B Cell Development, Mary Attaway, Tzippora Chwat-Edelstein, Bao Q. Vuong

Publications and Research

B cells play a significant role in the adaptive immune response by secreting immunoglobulins that can recognize and neutralize foreign antigens. They develop from hematopoietic stem cells, which also give rise to other types of blood cells, such as monocytes, neutrophils, and T cells, wherein specific transcriptional programs define the commitment and subsequent development of these different cell lineages. A number of transcription factors, such as PU.1, E2A, Pax5, and FOXO1, drive B cell development. Mounting evidence demonstrates that non-coding RNAs, such as microRNAs (miRNAs) and long non-coding RNAs (lncRNAs), modulate the expression of these transcription factors directly by binding …

The ~300 km long Dauki Fault demarcates the elevated Shillong Plateau, part of the Indian Shield to the north and the deep basin to the south. The basin experienced three strong to major intraplate earthquakes: a) 1885 Bengal earthquake (rev. Mw 6.8) close to the Hinge Zone, b) 1918 Srimangal earthquake (rev. Mw 7.1) on the Sylhet (trough) fault and c) …

Expression, Purification And Refolding Of A Human Na V 1.7 Voltage Sensing Domain With Native-Like Toxin Binding Properties, Ryan V. Schroder, Leah S. Cohen, Ping Wang, Joekeem D. Arizala, Sébastien F. Poget

Publications and Research

The voltage-gated sodium channel NaV1.7 is an important target for drug development due to its role in pain perception. Recombinant expression of full-length channels and their use for biophysical characterization of interactions with potential drug candidates is challenging due to the protein size and complexity. To overcome this issue, we developed a protocol for the recombinant expression in E. coli and refolding into lipids of the isolated voltage sensing domain (VSD) of repeat II of NaV1.7, obtaining yields of about 2 mg of refolded VSD from 1 L bacterial cell culture. This VSD is known to be involved in the …

Publications and Research

Diet quality scores are designed mainly based on Western-style dietary patterns. They were demonstrated to be good indicators of obesity in developed but not developing countries. Several diet quality scores were developed based on the Chinese dietary guidelines, yet no systematic review exists regarding how they were related to obesity. We searched research articles published between 2000 and 2021 in PubMed, CINAHL, and Scopus databases. Both cross-sectional and prospective studies that examined the relationship between a diet quality score and weight, body mass index, obesity, or waist circumference conducted in a Chinese population were selected. From the 602 articles searched, …

Determination Of Sustainable Zones For Groundwater Abstraction From The Multi-Layered Aquifer System In The Bengal Basin, Bangladesh, Anwar Zahid, Muhammad Qumrul Hassan, Nazrul I. Khandaker

Publications and Research

The use of deep groundwater (±300 m deep) is becoming an important issue in the Bengal Basin, due to both water quality problems and an acute shortage of available water in upper aquifers. In southeastern Bangladesh, multi-layered aquifer conditions exist with arsenic contamination at shallow depths, and high iron and brackish groundwater occurring mainly in the deeper layers. Many previous studies have offered explanations for the high concentrations of dissolved arsenic in groundwater - most of which proposed that the arsenic is derived from geo-genic sources and its release in groundwater is through natural processes, not the result of anthropogenic …

The Importance Of Monitoring To Assess The Impact Of Climate Change On Groundwater Resources In Bangladesh, Muhammad Qumrul Hassan, Anwar Zahid, Nazrul I. Khandaker

Publications and Research

Groundwater is the major source of fresh water across much of the world, but there has been very little study on the impacts of climate change on this precious and finite resource. Rising levels of greenhouse gases are likely to increase the global average surface temperature over the next 100 years, raise sea levels and reduce soil moisture. The amount of water stored in the soil is fundamentally important to agriculture and influences the rate of actual evaporation, groundwater recharge and runoff. Rising sea levels would cause the tidal saltwater wedge to intrude further upstream in rivers, with resulting changes …

Multi-Faceted Geoscience Research Using Open Access Resources: The Successful Participation Of K9-16 Students, Nazrul I. Khandaker, Noshin Sharmili, Omadevi Singh, Gurwinder Sahota, Sol De Leon, Matthew Khargie, Ali Zarine, Krishna Mahabir, Adacia Teemal, Mildred M. Selby

Publications and Research

Students interested in geosciences, for the most part, missed out their traditional field- based research activities due to strict social distancing, travel restrictions and/or lacking financial support. An absence of physical laboratory opportunities forced students to choose topics deemed doable through online research. Available data from online sources on extreme weather related case studies, flooding, droughts, groundwater depletion in urban and suburban areas, coastal erosion rate, sealevel rise, landslides, earthquakes, volcanic eruptions, and atmospheric pollution became quite handy and lucrative. Readily available pertinent data sources enabled K9-16 students to conduct summer research at “stay home” situations. Selective peer mentoring was …

Ecological Selectivity And The Evolution Of Mammalian Substrate Preference Across The K–Pg Boundary, Jonathan J. Hughes, Jacob S. Berv, Stephen G. B. Chester, Eric J. Sargis, Daniel J. Field

Publications and Research

The Cretaceous–Paleogene (K–Pg) mass extinction 66 million years ago was characterized by a worldwide ecological catastrophe and rapid species turnover. Large-scale devastation of forested environments resulting from the Chicxulub asteroid impact likely influenced the evolutionary trajectories of multiple clades in terrestrial environments, and it has been hypothesized to have biased survivorship in favour of nonarboreal lineages across the K–Pg boundary. Here, we evaluate patterns of substrate preferences across the K–Pg boundary among crown group mammals, a group that underwent rapid diversification following the mass extinction. Using Bayesian, likelihood, and parsimony reconstructions, we identify patterns of mammalian ecological selectivity that are …

Partisanship And The Politics Of Covid Vaccine Hesitancy, David Jones, Monika L. Mcdermott

Publications and Research

Has partisan polarization reached the stage that it now affects Americans’ decisions whether or not to get vaccinated against a pervasive and deadly virus such as COVID-19? To date, the evidence has largely been hypothetical—collected before the vaccine was widely available—superficial, or contradictory. Using two original surveys conducted at two different time periods after vaccines became available, this study represents one of the first efforts to systematically analyze the role of party affiliation in predicting vaccine hesitancy. We find that even after controlling for a host of demographic and attitudinal variables, Republicans are significantly less likely—and Democrats more likely—to be …

We used an internet-based survey platform to conduct a cross-sectional survey regarding the impact of COVID-19 on the LGBTQ + population in the United States. While this method of data collection was quick and inexpensive, the data collected required extensive cleaning due to the infiltration of bots. Based on this experience, we provide recommendations for ensuring data integrity. Recruitment conducted between May 7 and 8, 2020 resulted in an initial sample of 1251 responses. The Qualtrics survey was disseminated via social media and professional association listservs. After noticing data discrepancies, research staff developed a rigorous data cleaning protocol. A second …

Wave Function Identity: A New Symmetry For 2-Electron Systems In An Electromagnetic Field, Marlina Slamet, Viraht Sahni

Publications and Research

Stationary-state Schrödinger-Pauli theory is a description of electrons with a spin moment in an external electromagnetic field. For 2-electron systems as described by the Schrödinger-Pauli theory Hamiltonian with a symmetrical binding potential, we report a new symmetry operation of the electronic coordinates. The symmetry operation is such that it leads to the equality of the transformed wave function to the wave function. This equality is referred to as the Wave Function Identity. The symmetry operation is a two-step process: an interchange of the spatial coordinates of the electrons whilst keeping their spin moments unchanged, followed by an inversion. The Identity …

Development Of Predictive Models For Water Budget Simulations Of Closed-Basin Lakes: Case Studies Of Lakes Azuei And Enriquillo On The Island Of Hispaniola, Mahrokh Moknatian, Michael Piasecki

Publications and Research

The historical water level fluctuations of the two neighboring Caribbean lakes of Azuei (LA) and Enriquillo (LE) on Hispaniola have shown random periods of synchronous and asynchronous behaviors, with both lakes exhibiting independent dynamics despite being exposed to the same climatic forces and being directly next to each other. This paper examines their systems' main drivers and constraints, which are used to develop numerical models for these two lakes. The water balance approach was employed to conceptually model the lakes on an interannual scale and examine the assumptions of surface and subsurface processes. These assumptions were made based on field …

Buffy the Vampire Slayer was once heralded as a beacon of feminist power on television in a sea of one-dimensional wives, girlfriends, and supporting characters. Joss Whedon, its creator, has been hailed as a feminist icon and a lifesaver of kids and adults struggling with being different (Cochran). “Geeks love Joss Whedon” according to a 2012 Wired article: “His characters are smart and self-aware. He’s steeped in pop culture and has a clever way with twists and turns of science fiction tropes […] plus, he writes female character who kick ass, which makes him so rare as to be sui …

"Writing Unspeakable Things: Speechlessness, Abjection, And The Ethics/Aesthetics Of (Not) Representing Sexual Violence In Three Korean American "Comfort Women' Novels", M Laura Barberan Reinares

Publications and Research

This article analyzes “comfort women” novels by the Korean American authors Therese Park, Nora Okja Keller, and Chang-rae Lee in terms of the ethics and aesthetics of representing sexual violence through language. I specifically look at these authors’ stylistic strategies to describe rape in writing and how they (more or less successfully) avoid voyeuristic portrayals of the “comfort women” by controlling the narrative point of view and relying on traumatic “speechlessness” and abjection. Building on relevant notions from the fields of photography, cinematography, philosophy, and psychoanalysis, this analysis suggests that in-progress representations of rape in language become a futile project …
