Terrapin Station: Individual, Sex, And Site Factors Related To Turtle Growth Variability, Leigh Anne Harden, Stephen R. Midway, J. Whitfield Gibbons

Faculty Publications

For many turtle species, life history traits such as body size, age at maturity, and somatic growth rate can vary among individuals and habitats and between the sexes. Therefore, it is important to consider factors that may influence growth when modeling (somatic) growth for turtles. Long-term capture-mark-recapture studies lend themselves to studying somatic growth in turtles due to the repeated measurements of individuals over time. We used a long-term dataset to examine growth patterns of philopatric Diamondback Terrapins (Malaclemys terrapin) on Kiawah Island, South Carolina, USA. We used a hierarchical three-parameter von Bertalanffy model to estimate individual growth of 44 …

Shark Side Of The Moon: Are Shark Attacks Related To Lunar Phase?, Lindsay A. French, Stephen R. Midway, David H. Evans, George H. Burgess

Faculty Publications

Animals across taxa have shown behaviors linked to moon phase (or the proxy of lunar illumination), and marine organisms are well-documented to calibrate certain activities with the moon. Few studies have looked at a possible connection between moon phase and shark attacks on humans, and the results have been preliminary or lacking relationships. We used nearly 50 years of shark attack data from across the globe to test for a relationship between shark attacks and moon phase. We examined factors of geography, shark species, and outcome of attack. From 12 relationships that we tested (totaling 120 comparisons), we found 12 …

Tropical Cyclones Cumulatively Control Regional Carbon Fluxes In Everglades Mangrove Wetlands (Florida, Usa), Xiaochen Zhao, Victor H. Rivera-Monroy, Luis M. Farfán, Henry Briceño, Edward Castañeda-Moya, Rafael Travieso, Evelyn E. Gaiser

Faculty Publications

Mangroves are the most blue-carbon rich coastal wetlands contributing to the reduction of atmospheric CO2 through photosynthesis (sequestration) and high soil organic carbon (C) storage. Globally, mangroves are increasingly impacted by human and natural disturbances under climate warming, including pervasive pulsing tropical cyclones. However, there is limited information assessing cyclone’s functional role in regulating wetlands carbon cycling from annual to decadal scales. Here we show how cyclones with a wide range of integrated kinetic energy (IKE) impact C fluxes in the Everglades, a neotropical region with high cyclone landing frequency. Using long-term mangrove Net Primary Productivity (Litterfall, NPPL) data (2001–2018), …

Domoic Acid And Pseudo-Nitzschia Spp. Connected To Coastal Upwelling Along Coastal Inhambane Province, Mozambique: A New Area Of Concern, Holly Kelchner, Katie E. Reeve-Arnold, Kathryn M. Schreiner, Sibel Bargu, Kim G. Roques, Reagan M. Errera

Faculty Publications

Harmful algal blooms (HABs) are increasing globally in frequency, persistence, and geo-graphic extent, posing a threat to ecosystem and human health. To date, no occurrences of marine phycotoxins have been recorded in Mozambique, which may be due to absence of a monitoring program and general awareness of potential threats. This study is the first documentation of neurotoxin, domoic acid (DA), produced by the diatom Pseudo-nitzschia along the east coast of Africa. Coastal Inhambane Province is a biodiversity hotspot where year-round Rhincodon typus (whale shark) sightings are among the highest globally and support an emerging ecotourism industry.

Geochemical chronologies were constructed from otoliths of adult Pacific bluefin tuna (PBT) to investigate the timing of age-specific egress of juveniles from coastal nurseries in the East China Sea or Sea of Japan to offshore waters of the Pacific Ocean. Element:Ca chronologies were developed for otolith Li, Mg, Mn, Zn, Sr, and Ba, and our assessment focused on the section of the otolith corresponding to the age-0 to age-1 + interval. Next, we applied a common time-series approach to geochemical profiles to identify divergences presumably linked to inshore-offshore migrations. Conspicuous geochemical shifts were detected during the juvenile interval for Mg:Ca, …

The Effect Of Door Opening On Air-Mixing In A Positively Pressurized Room: Implications For Operating Room Air Management During The Covid Outbreak, Arup Bhattacharya, Ali Ghahramani, Ehsan Mousavi

Faculty Publications

The effect of the built environment on the predominant indoor airflow patterns is significant. To protect the healthcare workers at the front line from the outbreak of COVID − 19, it is necessary to understand the transmission dynamics of the virus, which has been shown to depend on indoor airflow patterns. In hospital operating rooms (ORs), design requirements pose a unique challenge as the positive pressure in the OR can facilitate virus spread into adjacent spaces, shall a COVID-positive patient require a surgical procedure. Moreover, the turbulent vortexes from door motions could independently increase the probability of virus escape from …

Exploring Thermal State In Mixed Immersive Virtual Environments, Sanaz Saeidi, Girish Rentala, Tracey Rizzuto, Tianzhen Hong, Neil Johannsen, Yimin Zhu

Faculty Publications

Combining immersive virtual environment (IVE) with a controlled environment is a potential solution for analyzing human thermal experience during building design. Existing studies in this field have not adequately analyzed scenarios involving stabilized comfortable and uncomfortable temperature conditions using both thermal state votes and physiological responses, or the influence of the seasons. By combining IVE with a climate chamber, called mixed IVE (MIVE) in this study, experiments were conducted to test the hypothesis that participants' virtual experience did not significantly alter their thermal experience compared to their in-situ experience. Response variables were the control temperature distribution, the thermal state vote …

Isolating The White Matter Circuitry Of The Dorsal Language Stream: Connectome-Symptom Mapping In Stroke Induced Aphasia, Vatche Baboyan, Alexandra Basilaskos, Grigori Yourganov, Chris Rorden, Leonardo Bonilha, Julius Fridiksson, Gregory Hickok

Faculty Publications

The application of �� 1 -regularized machine learning models to high-dimensional connectomes offers a promising methodology to assess clinical-anatomical correlations in humans. Here, we integrate the connectome-based lesion-symptom mapping framework with sparse partial least squares regression (sPLS-R) to isolate elements of the connectome associated with speech repetition deficits. By mapping over 2,500 connections of the structural connectome in a cohort of 71 stroke-induced cases of aphasia presenting with varying left-hemisphere lesions and repetition impairment, sPLS-R was trained on 50 subjects to algorithmically identify connectomic features on the basis of their predictive value. The highest ranking features were subsequently used to …

Devfold: A Toolbox For Designing Age-Specific Fnirs Channel Placement, Xiaoxue (Jessie) Fu Ph.D., John E. Richards

Faculty Publications

Significance: Near-infrared spectroscopy (NIRS) is a noninvasive technique that uses scalp-placed sensors to measure cerebral hemoglobin concentration. Commercial NIRS instruments do not allow for whole-head coverage and do not intrinsically indicate which brain areas generate the NIRS signal. Hence, the challenge is to design source–detector channel arrangement that maximizes sensitivity to a given brain region of interest (ROI). Existing methods for optimizing channel placement design have been developed using adult head models. Thus, they have limited utility for developmental research.

Aim: We aim to build an application from an existing toolbox (fOLD) that guides NIRS channel configuration based on age …

Evidentiary Inequality, Sandra F. Sperino

Faculty Publications

Federal employment discrimination law is rife with evidentiary inequality. Courts allow employers to draw from a broad palette of evidence to defend against discrimination claims, while highly restricting the facts from which plaintiffs can prove their claims. This Article draws from hundreds of cases to show how judges favor the employer's evidence and disfavor the plaintiff's evidence across multiple dimensions, such as time, witnesses, documents, relevance, and reliability. Judges have created a host of named doctrines that severely restrict the evidence plaintiffs are allowed to use to prove their discrimination claims. At the same time, a host of unnamed, and …

Small to moderate benefits of caffeine use include, but are not limited to: muscular endurance, movement velocity and muscular strength, sprinting, jumping, and throwing performance, as well as a wide range of aerobic and anaerobic sport-specific actions.2.Aerobic endurance appears to be the form of exercise with the most consistent moderate-to-large benefits from caffeine use, although the magnitude of …

Non-Local Corrections To The Typical Medium Theory Of Anderson Localization, H. Terletska, A. Moilanen, K. M. Tam, Y. Zhang, Y. Wang, M. Eisenbach, N. S. Vidhyadhiraja, L. Chioncel, J. Moreno

Faculty Publications

We use the recently developed finite cluster typical medium approach to study the Anderson localization transition in three dimensions. Applying our method to the box and binary alloy disorder distributions, we find a fast convergence with the cluster size. We demonstrate the importance of the typical medium environment and the non-local spatial correlations for the proper characterization of the localization transition. As the cluster size increases, our typical medium cluster method recovers the correct critical disorder strength for the transition. Our findings highlight the importance of the non-local cluster corrections for capturing the localization behavior of the mobility edge trajectories. …

Supermassive black holes and supernova explosions at the centres of active galaxies power cycles of outflowing and inflowing gas that affect galactic evolution and the overall structure of the Universe(1,2). While simulations and observations show that this must be the case, the range of physical scales (over ten orders of magnitude) and paucity of available tracers make both the simulation and observation of these effects difficult(3,4). By serendipity, there lies an active galaxy, Centaurus A (NGC 5128)(5,6), at such a close proximity as to allow its observation over this entire range of scales and across the entire electromagnetic spectrum.

Degradative Tubular Lysosomes Link Pexophagy To Starvation And Early Aging In C. Elegans, D A. Dolese, M P. Junot, B Ghosh, T J. Butsch, D A. Dolese, K A. Bohnert

Faculty Publications

Organelle-specific autophagy directs degradation of eukaryotic organelles under certain conditions. Like other organelles, peroxisomes are subject to autophagic turnover at lysosomes. However, peroxisome autophagy (pexophagy) has yet to be analyzed in a live-animal system, limiting knowledge on its regulation during an animal's life. Here, we generated a tandem-fluorophore reporter that enabled real-time tracking of pexophagy in live Caenorhabditis elegans. We observed that pexophagy occurred at a population of non-canonical, tubular lysosomes specifically during starvation and aging. Remarkably, in these contexts, tubular lysosomes were the predominant type of lysosome in the intestine, transforming from vesicles. Though we found that peroxisomes were …

The Dynamics Of Introgression Across An Avian Radiation, S Singhal, G E. Derryberry, G A. Bravo, E P. Derryberry, S Singhal, M G. Harvey

Faculty Publications

Hybridization and resulting introgression can play both a destructive and a creative role in the evolution of diversity. Thus, characterizing when and where introgression is most likely to occur can help us understand the causes of diversification dynamics. Here, we examine the prevalence of and variation in introgression using phylogenomic data from a large (1300+ species), geographically widespread avian group, the suboscine birds. We first examine patterns of gene tree discordance across the geographic distribution of the entire clade. We then evaluate the signal of introgression in a subset of 206 species triads using Patterson's D-statistic and test for associations …

Faculty Publications

For almost two decades, researchers have observed the preservation of the quantum statistical properties of bosons in a large variety of plasmonic systems. In addition, the possibility of preserving nonclassical correlations in light-matter interactions mediated by scattering among photons and plasmons stimulated the idea of the conservation of quantum statistics in plasmonic systems. It has also been assumed that similar dynamics underlie the conservation of the quantum fluctuations that define the nature of light sources. So far, plasmonic experiments have been performed in nanoscale systems in which complex multiparticle interactions are restrained. Here, we demonstrate that the quantum statistics of …

Scalable Multiphoton Quantum Metrology With Neither Pre- Nor Post-Selected Measurements, Chenglong You, Mingyuan Hong, Peter Bierhorst, Adriana E. Lita, Scott Glancy, Steve Kolthammer, Emanuel Knill, Sae Woo Nam, Richard P. Mirin, Omar S. Magaña-Loaiza, Thomas Gerrits

Faculty Publications

The quantum statistical fluctuations of electromagnetic fields establish a limit, known as the shot-noise limit, on the sensitivity of optical measurements performed with classical technologies. However, quantum technologies are not constrained by this shot-noise limit. In this regard, the possibility of using every photon produced by quantum sources of light to estimate small physical parameters, beyond the shot-noise limit, constitutes one of the main goals of quantum optics. Here, we experimentally demonstrate a scalable protocol for quantum-enhanced optical phase estimation across a broad range of phases, with neither pre- nor post-selected measurements. This is achieved through the efficient design of …

Controllable Quantum Point Junction On The Surface Of An Antiferromagnetic Topological Insulator, Nicodemos Varnava, Justin H. Wilson, J. H. Pixley, David Vanderbilt

Faculty Publications

Engineering and manipulation of unidirectional channels has been achieved in quantum Hall systems, leading to the construction of electron interferometers and proposals for low-power electronics and quantum information science applications. However, to fully control the mixing and interference of edge-state wave functions, one needs stable and tunable junctions. Encouraged by recent material candidates, here we propose to achieve this using an antiferromagnetic topological insulator that supports two distinct types of gapless unidirectional channels, one from antiferromagnetic domain walls and the other from single-height steps. Their distinct geometric nature allows them to intersect robustly to form quantum point junctions, which then …

Rare Regions And Avoided Quantum Criticality In Disordered Weyl Semimetals And Superconductors, J. H. Pixley, Justin H. Wilson

Faculty Publications

Disorder in Weyl semimetals and superconductors is surprisingly subtle, attracting attention and competing theories in recent years. In this brief review, we discuss the current theoretical understanding of the effects of short-ranged, quenched disorder on the low energy-properties of three-dimensional, topological Weyl semimetals and superconductors. We focus on the role of non-perturbative rare region effects on destabilizing the semimetal phase and rounding the expected semimetal-to-diffusive metal transition into a cross over. Furthermore, the consequences of disorder on the resulting nature of excitations, transport, and topology are reviewed. New results on a bipartite random hopping model are presented that confirm previous …

Solid-State Nmr Of Unlabeled Plant Cell Walls: High-Resolution Structural Analysis Without Isotopic Enrichment, Wancheng Zhao, Alex Kirui, Fabien Deligey, Frederic Mentink-Vigier, Yihua Zhou, Baocai Zhang, Tuo Wang

Faculty Publications

© 2021, The Author(s). Background: Multidimensional solid-state nuclear magnetic resonance (ssNMR) spectroscopy has emerged as an indispensable technique for resolving polymer structure and intermolecular packing in primary and secondary plant cell walls. Isotope (13C) enrichment provides feasible sensitivity for measuring 2D/3D correlation spectra, but this time-consuming procedure and its associated expenses have restricted the application of ssNMR in lignocellulose analysis. Results: Here, we present a method that relies on the sensitivity-enhancing technique Dynamic Nuclear Polarization (DNP) to eliminate the need for 13C-labeling. With a 26-fold sensitivity enhancement, a series of 2D 13C–13C correlation spectra were successfully collected using the unlabeled …

Soybean Leaf Age And Plant Stage Influence Expression Of Resistance To Velvetbean Caterpillar And Fall Armyworm, Bruno H.S. Souza, Eduardo N. Costa, Zulene A. Ribeiro, Bruno Perlatti, Mara C.P. Cruz, Moacir R. Forim, Arlindo L.Boiça Júnior, Michael J. Stout

Faculty Publications

Numerous species of herbivorous insects are associated with soybeans, including the specialist velvetbean caterpillar (VBC), Anticarsia gemmatalis, and the generalist fall armyworm (FAW), Spodoptera frugiperda. Expression of plant resistance is influenced by factors intrinsic to host plants, such as leaf age and plant stage, which can differentially affect specialist and generalist insects due to varying levels of plant defense and corresponding insect adaptation. In this study, four experiments were carried out to test the hypotheses that levels of antibiosis-resistance to VBC and FAW in the resistant genotype PI 227,687 and susceptible genotype IGRA RA 626 RR are related to leaf …
