Exploring A Novel Substrate-Borne Vibratory Signal In The Wolf Spider Schizocosa Floridana, Malcolm F. Rosenthal, Eileen Hebets, Rowan H. Mcginley, Cody Raiza, James Starrett, Lin Yan, Damian O. Elias

Eileen Hebets Publications

Animals communicate using a diversity of signals produced by a wide array of physical structures. Determining how a signal is produced provides key insights into signal evolution. Here, we examine a complex vibratory mating display produced by male Schizocosa floridana wolf spiders. This display contains three discrete substrate-borne acoustic components (known as “thumps”, “taps”, and “chirps”), each of which is anecdotally associated with the movement of a different body part (the pedipalps, legs, and abdomen respectively). In order to determine the method of production, we employ a combination of high-speed video/audio recordings and SEM imaging of possible sound-producing structures. Previous …

Testing The Hypothesized Antipredator Defence Function Of Stridulation In The Spiny Orb-Weaving Spider, Micrathena Gracilis, Tyler B. Corey, Eileen A. Hebets

Eileen Hebets Publications

The observable diversity of antipredator defenses across organisms demonstrates predation’s impact on trait evolution. The functions of many traits that are presumed to have an antipredator function have never been directly tested. The spiny orb-weaving spider, Micrathena gracilis, for example, stridulates when grasped. While stridulation was first hypothesized to be an antipredator defense nearly 50 years ago, no data exist to support this hypothesis. To explore the form and function of M. gracilis stridulation, we first quantified the behavioral and acoustical properties of sound production. Next, using laboratory assays, we directly tested the effect of stridulation on survival with …

A One Health Framework To Estimate The Cost Of Antimicrobial Resistance, Chantal Morel, Richard Alm, Christine Årdal, Alessandra Bandera, Giacomo Bruno, Elena Carrara, Giorgio Colombo, Marlieke De Kraker, Sabiha Essack, Isabel Frost, Bruno Gonzalez-Zorn, Herman Goossens, Luca Guardabassi, Stephan Harbarth, Peter Jørgensen, Souha Kanj, Tomislav Kostyanev, Ramanan Laxminarayan, Finola Leonard, Gabriel Levy Hara, Marc Mendelson, Malgorzata Mikulska, Nico Mutters, Kevin Outterson, Jesus Rodriguez Baňo, Evelina Tacconelli, Luigia Scudeller

Faculty Scholarship

Objectives/purpose

The costs attributable to antimicrobial resistance (AMR) remain theoretical and largely unspecified. Current figures fail to capture the full health and economic burden caused by AMR across human, animal, and environmental health; historically many studies have considered only direct costs associated with human infection from a hospital perspective, primarily from high-income countries. The Global Antimicrobial Resistance Platform for ONE-Burden Estimates (GAP-ON€) network has developed a framework to help guide AMR costing exercises in any part of the world as a first step towards more comprehensive analyses for comparing AMR interventions at the local level as well as more harmonized …

Adaptive Divergence, Neutral Panmixia, And Algal Symbiont Population Structure In The Temperate Coral Astrangia Poculata Along The Mid-Atlantic United States, Hannah E. Aichelman, Daniel J. Barshis

Biological Sciences Faculty Publications

Astrangia poculata is a temperate scleractinian coral that exists in facultative symbiosis with the dinoflagellate alga Breviolum psygmophilum across a range spanning the Gulf of Mexico to Cape Cod, Massachusetts. Our previous work on metabolic thermal performance of Virginia (VA) and Rhode Island (RI) populations of A. poculata revealed physiological signatures of cold (RI) and warm (VA) adaptation of these populations to their respective local thermal environments. Here, we used whole-transcriptome sequencing (mRNA-Seq) to evaluate genetic differences and identify potential loci involved in the adaptive signature of VA and RI populations. Sequencing data from 40 A. poculata individuals, including 10 …

Techno-Economic Optimization Of Food Waste Diversion To Treatment Facilities To Determine Cost Effectiveness Of Policy Incentives, Kanwal Shahid

Theses

New York state recently passed a food waste (FW) disposal ban, which will prohibit land-filling of FW produced by commercial entities generating more than 2 tons/week by the year 2022. This will redirect 370,000 tons/year of FW from landfills. In this work, we investigate three questions about the landfill ban: 1) How can this waste be diverted to treatment facilities at lowest system cost? 2) To what degree can an expanded anaerobic digestion portfolio help with the state’s Renewable Portfolio Standards? 3) What policies can help with the transition of waste-to-energy technologies? We develop a mixed-integer linear programming model that …

Finding A Place For World War I In American History: 1914-2018, Jennifer D. Keene

History Faculty Books and Book Chapters

"World War I has occupied an uneasy place in the American public and political consciousness.1 In the 1920s and 1930s, controversies over the war permeated the nation’s cultural and political life, influencing memorial culture and governmental policy. Interest in the war, however, waned considerably after World War II, a much larger and longer war for the United States. Despite a plethora of scholarly works examining nearly every aspect of the war, interest in the war remains limited even among academic historians. In many respects, World War I became the “forgotten war” because Americans never developed a unifying collective memory about …

Modeling Age-Dependent Developmental Changes In The Expression Of Genes Involved In Citrulline Synthesis Using Pig Enteroids, Mahmoud A Mohammad, Inka C Didelija, Barbara Stoll, Douglas G Burrin, Juan C Marini

Children’s Nutrition Research Center Staff Publications

metabolism of citrulline and arginine are well characterized. Enteroids, a novel ex-vivo model that recreates the three-dimensional structure of the intestinal crypt-villus unit, have shown to replicate molecular and physiological profiles of the intestinal segment from where they originated ("location memory").

Objective: The present study tested the hypothesis that enteroids recapitulate the developmental changes observed in vivo regarding citrulline production in pigs ("developmental memory").

Methods: Preterm (10- and 5-d preterm) and term pigs at birth, together with 7- and 35-d-old pigs were studied. Gene expression was measured in jejunal samples and in enteroids derived from this segment. Whole body citrulline …

Tangi: Tangible Proxies For Embodied Object Exploration And Manipulation In Virtual Reality, Martin Feick, Scott Bateman, Anthony Tang, Anthony Tang

Research Collection School Of Computing and Information Systems

Exploring and manipulating complex virtual objects is challenging due to limitations of conventional controllers and free-hand interaction techniques. We present the TanGi toolkit which enables novices to rapidly build physical proxy objects using Composable Shape Primitives. TanGi also provides Manipulators allowing users to build objects including movable parts, making them suitable for rich object exploration and manipulation in VR. With a set of different use cases and applications we show the capabilities of the TanGi toolkit and evaluate its use. In a study with 16 participants, we demonstrate that novices can quickly build physical proxy objects using the Composable Shape …

Understanding how global change drivers (GCDs) affect aboveground net primary production (ANPP) through time is essential to predicting the reliability and maintenance of ecosystem function and services in the future. While GCDs, such as drought, warming and elevated nutrients, are known to affect mean ANPP, less is known about how they affect inter-annual variability in ANPP. We examined 27 global change experiments located in 11 different herbaceous ecosystems that varied in both abiotic and biotic conditions, to investigate changes in the mean and temporal variability of ANPP (measured as the coefficient of variation) in response to different GCD manipulations, including …

A Question Of Scale: Making Meteorological Knowledge And Nation In Imperial Asia, Fiona Williamson, Vladimir Jankovic

Research Collection School of Social Sciences

This special issue of History of Meteorology explores processes of making, communicating, and embedding modern meteorological knowledge in late nineteenth and early twentieth century imperial Asia. Its focus is on the institutionalisation of meteorology in key nation-building activities such as developing agricultural services, synoptic mapping to predict storms, and participation in scientific organisations and initiatives. Collectively, the essays explore the intersection of local, regional, and international scales and processes in generating new forms of state-sponsored meteorological practices and institutions, though complex multi-layered networks involving different actors and modes of information flow across multiple scales. In so doing, they reveal the …

Adverse Health Effects Associated With Household Air Pollution: A Systematic Review, Meta-Analysis, And Burden Estimation Study, Kuan Ken Lee, Rong Bing, Joanne Kiang, Sophia Bashir, Nicholas Spath, Dominik Stelzle, Kevin Mortimer, Anda Bularga, Dimitrios Doudesis, Michael Chung

Internal Medicine, East Africa

Background: 3 billion people worldwide rely on polluting fuels and technologies for domestic cooking and heating. We estimate the global, regional, and national health burden associated with exposure to household air pollution.

Methods: For the systematic review and meta-analysis, we systematically searched four databases for studies published from database inception to April 2, 2020, that evaluated the risk of adverse cardiorespiratory, paediatric, and maternal outcomes from exposure to household air pollution, compared with no exposure. We used a random-effects model to calculate disease-specific relative risk (RR) meta-estimates. Household air pollution exposure was defined as use of polluting fuels (coal, wood, …

Wnt Signaling Determines Body Axis Polarity In Regenerating Hydra Tissue Fragments, R. Wang, R. E. Steele, Eva-Maria S. Collins

Biology Faculty Works

How an animal establishes its body axis is a fundamental question in developmental biology. The freshwater cnidarian Hydra is an attractive model for studying axis formation because it is radially symmetric, with a single oral-aboral axis. It was recently proposed that the orientation of the new body axis in a regenerating Hydra polyp is determined by the oral-aboral orientation of the actin-myosin contractile processes (myonemes) in the animal’s outer epithelial layer. However, it remained unclear how the oral-aboral polarity of the body axis would be defined. As Wnt signaling is known to control axis polarity in Hydra and bilaterians, we …

Free Speech, Rational Deliberation, And Some Truths About Lies, Alan K. Chen

William & Mary Law Review

Could “fake news” have First Amendment value? This claim would seem to be almost frivolous given the potential for fake news to undermine two core functions of the freedom of speech—promoting democracy and facilitating the search for “truth,” as well as the corollary that to be valuable, speech must promote rational deliberation. Some would therefore claim that fake news should be classified as “no value” speech falling outside of the First Amendment’s reach. This Article argues somewhat counterintuitively that fake news has value because speech doctrine should not be focused exclusively on the promotion of rational deliberation, but should also …

Characterizing Prenatal Maternal Distress With Unique Prenatal Cortisol Trajectories, Gage Peterson, Emma V. Espel, Elyssia Poggi Davis, Curt A. Sandman, Laura M. Glynn

Psychology Faculty Articles and Research

Objective: It is widely assumed that glucocorticoids represent a primary mechanism through which exposure to adversity and maternal psychological distress shape prenatal developmental trajectories of both mother and fetus. However, despite repeated investigations and the fact that prenatal cortisol has been reliably linked to developmental outcomes, the empirical evidence supporting an association between prenatal cortisol and maternal distress is scarce. In this study, a novel approach to assessing links between maternal prenatal psychological distress and gestational cortisol profiles, general growth mixture modeling (GGMM), was applied. Method: Measures of pregnancy anxiety, perceived stress, and state anxiety and depressive symptoms as well …

U.S. Settler Colonialism, White Supremacy, And The Racially Disparate Impacts Of Covid-19, Monika Batra Kashyap

Faculty Articles

This Essay contextualizes the racially disproportionate impacts of COVID-19 in the United States within a framework of settler colonialism in order to broaden the understanding of how structural inequality is produced, imposed, and maintained. A settler colonialism framework recognizes that the United States is a present-day settler colonial society whose laws, institutions and systems of governance continue to reenact the three processes upon which the United States was built—Indigenous elimination, anti-Black racism, and immigrant exploitation. This Essay connects these foundational processes—and their underlying White supremacist logics—to the disparate health impacts of COVID-19 on Indigenous, Black, and immigrant of color communities …

Speciation‐By‐Depth On Coral Reefs: Sympatric Divergence With Gene Flow Or Cryptic Transient Isolation?, Carlos Prada, Michael E. Hellberg

Biological Sciences Faculty Publications

The distributions of many sister species in the sea overlap geographically but are partitioned along depth gradients. The genetic changes leading to depth segregation may evolve in geographic isolation as a prerequisite to coexistence or may emerge during primary divergence leading to new species. These alternatives can now be distinguished via the power endowed by the thousands of scorable loci provided by second‐generation sequence data. Here, we revisit the case of two depth‐segregated, genetically isolated ecotypes of the nominal Caribbean candelabrum coral Eunicea flexuosa. Previous analyses based on a handful of markers could not distinguish between models of genetic …

Apoe-Modified Liposomes Mediate The Antitumour Effect Of Survivin Promoter-Driven Hsvtk In Hepatocellular Carcinoma, Xiuli Mu, Xi Wang, Yan Wei, Chaochao Wen, Qi Zhang, Chunyang Xu, Chang Liu, Chan Zhang, Fanxiu Meng, Na Zhao, Tao Gong, Rui Guo, Gongqin Sun, Gaopeng Li, Hongwei Zhang, Qin Qin, Jun Xu, Xiushan Dong, Lumei Wang, Baofeng Yu

Cell and Molecular Biology Faculty Publications

Hepatocellular carcinoma (HCC) is a prevalent malignant tumour with high global morbidity and mortality associated with its multiple aetiologies, poor prognosis, resistance to chemotherapeutic drugs and high rate of recurrence. Here, we evaluated a gene therapy strategy that targets HCC using the herpes simplex virus thymidine kinase/ganciclovir (HSVtk/GCV) suicide gene system in HCC cell lines and in an in vivo human HCC xenograft mouse model. Apolipoprotein E (ApoE)-modified liposomes were used for targeted gene delivery to the tumour tissue, and the survivin promoter was used to drive HSVtk expression in HCC cells. Our results showed that the survivin promoter was …

Extending The Functional Subnetwork Approach To A Generalized Linear Integrate-And-Fire Neuron Model, Nicholas Szczecinski, Roger Quinn, Alexander J. Hunt

Mechanical and Materials Engineering Faculty Publications and Presentations

Engineering neural networks to perform specific tasks often represents a monumental challenge in determining network architecture and parameter values. In this work, we extend our previously-developed method for tuning networks of non-spiking neurons, the “Functional subnetwork approach” (FSA), to the tuning of networks composed of spiking neurons. This extension enables the direct assembly and tuning of networks of spiking neurons and synapses based on the network’s intended function, without the use of global optimization ormachine learning. To extend the FSA, we show that the dynamics of a generalized linear integrate and fire (GLIF) neuronmodel have fundamental similarities to those of …

Reconstructing Racially Polarized Voting, Travis Crum

Duke Law Journal

Racially polarized voting makes minorities more vulnerable to discriminatory changes in election laws and therefore implicates nearly every voting rights doctrine. In Thornburg v. Gingles , the Supreme Court held that racially polarized voting is a necessary—but not a sufficient—condition for a vote dilution claim under Section 2 of the Voting Rights Act. The Court, however, has recently questioned the propriety of recognizing the existence of racially polarized voting. This colorblind approach threatens not only the Gingles factors but also Section 2’s constitutionality.

The Court treats racially polarized voting as a modern phenomenon. But the relevant starting point is the …

Network Analysis As A Tool To Understand Social Development In Spider Monkeys, Emily R. Boeving, Michelle A. Rodrigues, Eliza L. Nelson

Social and Cultural Sciences Faculty Research and Publications

The emerging field of network science has demonstrated that an individual's connectedness within their social network has cascading effects to other dimensions of life. Like humans, spider monkeys live in societies with high fission–fusion dynamics, and are remarkably social. Social network analysis (SNA) is a powerful tool for quantifying connections that may vary as a function of initiating or receiving social behaviors, which has been described as shifting social roles. In primatology, the SNA literature is dominated by work in catarrhines, and has yet to be applied to the study of development in a platyrrhine model. Here, SNA was utilized …

Growth Of Microalgae For Simultaneous Treatment Of Industrial Wastewater And Biodiesel Production, Mohammed Ahmad Tawfiq Abujayyab

Chemical and Petroleum Engineering Theses

The treatment of industrial wastewater contaminated with phenols is among the main challenges in the chemical, and particularly the petrochemical industry. Phenols, which present in considerable amounts in industrial wastewater, are toxic even at low concentrations. Therefore, it is essential to reduce their concentrations in water to harmless levels before being discharged. On the other hand, the dependence on the conventional fossil sources of energy, which is non-renewable, is not sustainable and can cause harmful environmental impacts. Therefore, in this work, the dual utilization of microalgae as a cheap and efficient means to remove phenolic compounds commonly found in refinery …
