Real Space Quantum Cluster Formulation For The Typical Medium Theory Of Anderson Localization, Ka Ming Tam, Hanna Terletska, Tom Berlijn, Liviu Chioncel, Juana Moreno

Faculty Publications

We develop a real space cluster extension of the typical medium theory (cluster-TMT) to study Anderson localization. By construction, the cluster-TMT approach is formally equivalent to the real space cluster extension of the dynamical mean field theory. Applying the developed method to the 3D Anderson model with a box disorder distribution, we demonstrate that cluster-TMT successfully captures the localization phenomena in all disorder regimes. As a function of the cluster size, our method obtains the correct critical disorder strength for the Anderson localization in 3D, and systematically recovers the re-entrance behavior of the mobility edge. From a general perspective, our …

Faculty Publications

Aspergillus flavus is a fungal pathogen that infects maize and produces aflatoxins. Host-Induced Gene Silencing (HIGS) has been shown to reduce host infection by various fungal pathogens. Here, the A. flavus alkaline protease (alk) gene was targeted for silencing through HIGS. An RNAi vector carrying a portion of the alk gene was incorporated into the B104 maize genome. Four out of eight transformation events containing the alk gene, Alk-3, Alk-4, Alk-7 and Alk-9, were self-pollinated to T4/T6 generations. At T3, the Alk-transgenic lines showed up to 87% reduction in aflatoxin accumulation under laboratory conditions. T4 transgenic Alk-3 and Alk-7 lines, …

Murine Trophoblast Stem Cells And Their Differentiated Cells Attenuate Zika Virus In Vitro By Reducing Glycosylation Of The Viral Envelope Protein, Biswas Neupane, Mona Fendereski, Farzana Nazneen, Yanlin Guo, Fengwei Bai

Faculty Publications

Zika virus (ZIKV) infection during pregnancy can cause devastating fetal neuropathological abnormalities, including microcephaly. Most studies of ZIKV infection in pregnancy have focused on post-implantation stage embryos. Currently, we have limited knowledge about how a pre-implantation stage embryo deals with a viral infection. This study investigates ZIKV infection on mouse trophoblast stem cells (TSCs) and their in vitro differentiated TSCs (DTSCs), which resemble the cellular components of the trophectoderm layer of the blastocyst that later develops into the placenta. We demonstrate that TSCs and DTSCs are permissive to ZIKV infection; however, ZIKV propagated in TSCs and DTSCs exhibit substantially lower …

Exploring Text Mining For Recent Consumer And Sensory Studies About Alternative Proteins, Ziyang Chen, Cristhiam Gurdian, Chetan Sharma, Witoon Prinyawiwatkul, Damir D. Torrico

Faculty Publications

Increased meat consumption has been associated with the overuse of fresh water, under-ground water contamination, land degradation, and negative animal welfare. To mitigate these problems, replacing animal meat products with alternatives such as plant-, insect-, algae-, or yeast-fermented-based proteins, and/or cultured meat, is a viable strategy. Nowadays, there is a vast amount of information regarding consumers’ perceptions of alternative proteins in scientific outlets. Sorting and arranging this information can be time-consuming. To overcome this drawback, text mining and Natural Language Processing (NLP) are introduced as novel approaches to obtain sensory data and rapidly identify current consumer trends. In this study, …

Vaccine Clinical Trials And Data Infrastructure, Ana Santos Rutschman

Faculty Publications

We find ourselves at a momentous turn in the history of vaccines. The COVID-19 pandemic triggered a quasi-global vaccine race that not only compressed vaccine research and development (R&D) timelines, but also paved the way for the administration of a new type of vaccine technology – mRNA vaccines, which work in substantially different ways from the vaccines in use before the pandemic.

While the process of bringing emerging COVID-19 vaccines to market has taken place in an unusually short timeframe, it was largely predicated on the same scientific and regulatory processes that govern the development, approval and deployment of new …

Election Observation Post-2020, Rebecca Green

Faculty Publications

The United States is in the midst of a crisis in confidence in elections, despite the many process protections baked into every stage of election administration. Part of the problem is that few Americans know just how rigorous the protections in place are, and most Americans have no concept of how modern elections are run. Election observation statutes are intended to provide a window for members of the public to learn about and oversee the process and to satisfy themselves that elections are fair and that outcomes are reliable. Yet in 2020, in part due to unforeseen pandemic conditions, election …

Leading Through Paradox In A Covid-19 World: Human Resources Comes Of Age, David G. Collings, Anthony J. Nyberg, Patrick M. Wright, John Mcmackin

Faculty Publications

The impact of the coronavirus disease (COVID-19) pandemic is unprecedented. At an organisational level, the crisis has been hugely disruptive, complex and fraught with ambiguity for leaders. The crisis is fundamentally a human one, making human resource (HR) leaders central in enabling organisations to manage through and ultimately exit the crisis successfully. We apply a paradox lens to understand the HR leadership challenges posed by the COVID-19 crisis. We argue that how the HR function responds to the challenges of the crisis and its role in mapping the exit route from the crisis are likely to shape the trajectory of …

Low Light Intensity Delays Vegetative Phase Change, Mingli Xu, Tieqiang Hu, R Scott Poethig

Faculty Publications

Plants that develop under low light (LL) intensity often display a phenotype known as the “shade tolerance syndrome (STS)”. This syndrome is similar to the phenotype of plants in the juvenile phase of shoot development, but the basis for this similarity is unknown. We tested the hypothesis that the STS is regulated by the same mechanism that regulates the juvenile vegetative phase by examining the effect of LL on rosette development in Arabidopsis (Arabidopsis thaliana). We found that LL prolonged the juvenile vegetative phase and that this was associated with an increase in the expression of the master …

Parameter Estimation And Application Of Anisotropic Yield Criteria For Cylindrical Aluminum Extrusions: Theoretical Developments And Stereodic Measurements, Farzana Yasmeen, Michael A. Sutton, Xiaomin Deng, Megan Ryan, Anthony P. Reynolds

Faculty Publications

Theoretical and experimental studies are presented to characterize the anisotropic plastic response under torsion loading of two nominally identical aluminum Al6061-T6 extruded round bars. Theoretical models are developed using isotropic (Von Mises 1913) and anisotropic (Barlat 1991) yield criteria, along with isotropic strain hardening formulae, to model post-yield behavior under simple torsion loading. For the case of simple shear loading, incremental plasticity theory is used to determine the theoretical elastic, plastic, and total shear strains. A set of experiments are performed to calibrate Barlat’s 1991 yield function. Several specimens are extracted at different orientations to the longitudinal direction of each …
