Multimodal astrocyte–neuron communications govern brain circuitry assembly and function. For example, through rapid glutamate release, astrocytes can control excitability, plasticity and synchronous activity of synaptic networks, while also contributing to their dysregulation in neuropsychiatric conditions. For astrocytes to communicate through fast focal glutamate release, they should possess an apparatus for Ca2+-dependent exocytosis similar to neurons. However, the existence of this mechanism has been questioned owing to inconsistent data and a lack of direct supporting evidence. Here we revisited the astrocyte glutamate exocytosis hypothesis by considering the emerging molecular heterogeneity of astrocytes and using molecular, bioinformatic and imaging approaches, together with …

Rigid: Recurrent Gan Inversion And Editing Of Real Face Videos, Yangyang Xu, Shengfeng He, Kwan-Yee K. Wong, Pingluo Luo

Research Collection School Of Computing and Information Systems

GAN inversion is indispensable for applying the powerful editability of GAN to real images. However, existing methods invert video frames individually often leading to undesired inconsistent results over time. In this paper, we propose a unified recurrent framework, named Recurrent vIdeo GAN Inversion and eDiting (RIGID), to explicitly and simultaneously enforce temporally coherent GAN inversion and facial editing of real videos. Our approach models the temporal relations between current and previous frames from three aspects. To enable a faithful real video reconstruction, we first maximize the inversion fidelity and consistency by learning a temporal compensated latent code. Second, we observe …

Diffuse3d: Wide-Angle 3d Photography Via Bilateral Diffusion, Yutao Jiang, Yang Zhou, Yuan Liang, Wenxi Liu, Jianbo Jiao, Yuhui Quan, Shengfeng He

Research Collection School Of Computing and Information Systems

This paper aims to resolve the challenging problem of wide-angle novel view synthesis from a single image, a.k.a. wide-angle 3D photography. Existing approaches rely on local context and treat them equally to inpaint occluded RGB and depth regions, which fail to deal with large-region occlusion (i.e., observing from an extreme angle) and foreground layers might blend into background inpainting. To address the above issues, we propose Diffuse3D which employs a pre-trained diffusion model for global synthesis, while amending the model to activate depth-aware inference. Our key insight is to alter the convolution mechanism in the denoising process. We inject depth …

Avian Scavenging In The Forensic Context, Austin Millwood

Senior Theses

Many cultures have recognized the importance of birds in scavenging. However, within forensic literature and research, avian scavenging is an understudied phenomenon. Despite this, researchers have shown that scavenging by birds is unique from other types of scavenging in that birds can rapidly cause complete skeletonization, leave relatively little bone damage, and can spread remains and artifacts over a large area. Here birds known to scavenge are explained in a biological context and then their effects on remains are analyzed. Birds are capable of completely scavenging human remains in as little as 5 hours, depending on many understudied factors. Avian …

Virtual Urban Siege: Modern Urban Siege And Swarming In Culiacán 2019 & 2023, Daniel Weisz Argomedo, Nathan P. Jones, Ph.D., John P. Sullivan, Ph.D.

Journal of Strategic Security

Modern urban siege is a metaphor for evolved urban campaigns. The template for such attacks draws from the tactics seen in the 26/11 Mumbai attack in 2008, and continued with the 2013 Westgate Mall attack in Kenya, the January 2015 Charlie Hebdo and Hyper Cacher attacks in Paris and the November 2015 attacks against the Stade de France and Bataclan. These virtual sieges employ swarming tactics, techniques, and procedures (TTPs) to provide a template for urban strife and insecurity. This article provides an overview of terrorist swarming tactics, expanding the aperture to review the use of similar TTPs by criminal …

Review: European Sources Of Human Dignity: A Commented Anthology Mette Lebech. Oxford: Peter Lang, 2019. Pp. 345. On The Problem Of Human Dignity: A Hermeneutical And Phenomenological Investigation Mette Lebech., Robert Mcnamara

International Dialogue

A coordinating feature of much contemporary discourse—philosophical and theological, social and cultural, political and legal—is the idea of human dignity. The sense of its necessity as an idea grounding and organizing thought, feeling, and action about the human being is shared across different and often otherwise contrary worldviews. But to what does the expression “human dignity” refer? What is human dignity? And why is it important? Anyone who has looked at the problem with anything more than a cursory glance knows that these are not easy questions, and Mette Lebech sets herself the task of attaining an answer in two …

Vagueness And Federal-State Relations, Joel S. Johnson

University of Chicago Law Review

This Article aims to clarify the content of the void-for-vagueness doctrine and defend its historical pedigree by drawing attention to a fundamental aspect of the Supreme Court’s vagueness decisions—that vagueness analysis significantly depends on whether the law at issue is a federal or state law. That simple distinction has considerable explanatory power. It reveals that the doctrine emerged in the late nineteenth century in response to two simultaneous changes in the legal landscape— first, the availability of Supreme Court due process review of state penal statutes under the Fourteenth Amendment, and second, a significant shift in how state courts construed …

Politics By Other Means: The Jurisprudence Of “Common Good Constitutionalism”, Brian Leiter

University of Chicago Law Review

Professor Adrian Vermeule proposes an alternative to what he sees as the two dominant schools of constitutional interpretation in the United States: originalism and what he usually calls “progressivism”¹ (by which he means what others call “living constitutionalism”² ). Against these approaches, he advocates for what Freudians might call a “return of the repressed”³: a recognition of the extent to which the “classical” natural law tradition’s concern with the “common good” has continued to animate our public law—explicitly for much of our history, he says, and implicitly more recently.

On Vermeule’s proposed alternative, courts (and other …

Career Influences Of Environmental Education Field Experiences, Lacey Day

School of Education and Leadership Student Capstone Theses and Dissertations

As an environmental educator who got her start exploring the various flora and fauna around me, it has always interested me to know whether the same experiences that got me to where I am today have also influenced others to pursue similar careers. This study, because of that initial interest, set out to determine How do environmental education field experiences influence college major and/or career choice in high school students? Through a 21 question, cross-sectional survey, high school students in Allegany County Public Schools were asked a series of questions pertaining to their environmental educational field experiences, their values and …

Twenty Years After Krieger V Law Society Of Alberta: Law Society Discipline Of Crown Prosecutors And Government Lawyers, Andrew Flavelle Martin

Articles, Book Chapters, & Popular Press

Krieger v. Law Society of Alberta held that provincial and territorial law societies have disciplinary jurisdiction over Crown prosecutors for conduct outside of prosecutorial discretion. The reasoning in Krieger would also apply to government lawyers. The apparent consensus is that law societies rarely exercise that jurisdiction. But in those rare instances, what conduct do Canadian law societies discipline Crown prosecutors and government lawyers for? In this article, I canvass reported disciplinary decisions to demonstrate that, while law societies sometimes discipline Crown prosecutors for violations unique to those lawyers, they often do so for violations applicable to all lawyers — particularly …

Animal Science Faculty Publications and Presentations

OBJECTIVE

Current cystotomy methods often implement the use of off-label devices, resulting in urocystolith extraction difficulty and potentially leading to postoperative complications and discomfort for the patient. The objective of this study was to create 3 novel 3-D printed cystotomy spoons that offer a dedicated solution for removing urocystoliths from a patient's urinary bladder.

ANIMALS

Clinical use of the 3 novel 3-D printed cystotomy spoons were ultimately evaluated in 4 dogs and 1 cat that presented for urocystotlith removal at 3 different veterinary hospitals in northwest Arkansas.

METHODS

The novel cystotomy spoons were designed using SolidWorks, 3-D printed with a …

Farnesol Brain Transcriptomics In Cns Inflammatory Demyelination, William J. Doyle, Dana Walters, Xutong Shi, Kristina Hoffman, Krisztian Magori, Jean-Baptiste Roullet, Javier Ochoa-Repáraz

Biology Faculty Publications and Presentations

Background: Farnesol (FOL) prevents the onset of experimental autoimmune encephalomyelitis (EAE), a murine model of multiple sclerosis (MS).

Objective: We examined the transcriptomic profile of the brains of EAE mice treated with daily oral FOL using next-generation sequencing (RNA-seq).

Methods: Transcriptomics from whole brains of treated and untreated EAE mice at the peak of EAE was performed.

Results: EAE-induced mice, compared to naïve, healthy mice, overall showed increased expression in pathways for immune response, as well as an increased cytokine signaling pathway, with downregulation of cellular stress proteins. FOL downregulates pro-inflammatory pathways and attenuates the immune response in EAE. FOL …

Underrepresentation Of Women In Exercise Science And Physiology Research Is Associated With Authorship Gender, Jessica J. James, Emilie A. Klevenow, Mira A. Atkinson, Emma E. Vosters, Elizabeth P.

Exercise Science Faculty Research and Publications

Historically, low representation of women participants in exercise science and physiology studies has led to a lack of understanding in the response of women to exercise and therapeutic interventions. We hypothesized that 1) the number of women authors, participants, and editorial board members increased over 30 years (1991–2021) and 2) larger representation of women as editors and authors is associated with more women participants. Gender (man/woman) of editorial board members (n = 394), authors (n = 5,735), and participants (n = 2,984,883) of 972 original research articles with human participants published in 1991 and 2021 …

The Biological Basis Of Sex Differences In Athletic Performance: Consensus Statement For The American College Of Sports Medicine, Sandra K. Hunter, Siddhartha S. Angadi, Aditi Bhargava, Joanna Harper, Angelica Lindén Hirschberg, Benjamin D. Levine, Kerrie L. Moreau, Natalie J. Nokoff, Nina S. Stachenfeld, Stéphane Bermon

Exercise Science Faculty Research and Publications

Biological sex is a primary determinant of athletic performance because of fundamental sex differences in anatomy and physiology dictated by sex chromosomes and sex hormones. Adult men are typically stronger, more powerful, and faster than women of similar age and training status. Thus, for athletic events and sports relying on endurance, muscle strength, speed, and power, males typically outperform females by 10%–30% depending on the requirements of the event. These sex differences in performance emerge with the onset of puberty and coincide with the increase in endogenous sex steroid hormones, in particular testosterone in males, which increases 30-fold by adulthood, …

Moderate Heat Stress-Induced Sterility Is Due To Motility Defects And Reduced Mating Drive In Caenorhabditis Elegans Males, Nicholas B. Sepulveda, Donald Chen, Lisa N. Petrella

Biological Sciences Faculty Research and Publications

Moderate heat stress negatively impacts fertility in sexually reproducing organisms at sublethal temperatures. These moderate heat stress effects are typically more pronounced in males. In some species, sperm production, quality and motility are the primary cause of male infertility during moderate heat stress. However, this is not the case in the model nematode Caenorhabditis elegans, where changes in mating behavior are the primary cause of fertility loss. We report that heat-stressed C. elegans males are more motivated to locate and remain on food and less motivated to leave food to find and mate with hermaphrodites than their unstressed counterparts. …

Elementary Teachers’ Perception Of Digital Resources Based On Student Achievement, Tanya R. Small

Doctor of Education (Ed.D)

Many factors impact teachers’ decisions about when and how to implement technology during instruction. However, a gap exists in understanding teachers’ motivations for technology integration and face-to-face instruction. Therefore, this qualitative case study explored how teachers’ perceptions of student achievement, motivation, classroom behaviors, and digital challenges influenced their decisions about using technology or direct instruction in the classroom setting. A group of 20 teachers from two southern Florida public elementary schools completed anonymous Likert-scale surveys; six teachers participated in semi-structured interviews. The findings determined via descriptive statistics and thematic analysis revealed that teachers’ inclusion of technology and traditional resources is …

Regulatory T (Treg) cells are inevitable to prevent deleterious immune responses to self and commensal microorganisms. Treg function requires continuous expression of the transcription factor (TF) FOXP3 and is divided into two major subsets: resting (rTregs) and activated (aTregs). Continuous T cell receptor (TCR) signaling plays a vital role in the differentiation of aTregs from their resting state, and in their immune homeostasis. The process by which Tregs differentiate, adapt tissue specificity, and maintain stable phenotypic expression at the transcriptional level is still inconclusivei. In this work, the role of BATF is investigated, which is induced in response to TCR …

The House Full Of Otters: Recalling Human–Sea Otter Relationships On An Indigenous Oregon Coast, Douglas Deur, Peter Hatch, Hannah Wellman

Anthropology Faculty Publications and Presentations

Sea otters have held a special role in the cultural, spiritual, and economic life of Native American communities throughout recorded time. Along the coast of what is now Oregon, Native oral traditions recall a rich history of human encounters with sea otters, and speak of the species’ ubiquity, significance, and sentience. Native people also hunted sea otters, fashioning their uniquely dense fur into chiefly robes and using the pelts in ways central to community life — presaging the species’ later role in the global fur trade. Archaeological evidence of sea otter use can be found in sites of diverse antiquity …

Object Recognition With Deep Neural Networks In Low-End Systems, Lillian Davis

Mahurin Honors College Capstone Experience/Thesis Projects

Object recognition is an important area in computer vision. Object recognition has been advanced significantly by deep learning that unifies feature extraction and classification. In general, deep neural networks, such as Convolution Neural Networks (CNNs), are trained in high-performance systems. Aiming to extend the reach of deep learning to personal computing, I propose a study of deep learning-based object recognition in low-end systems, such as laptops. This research includes how differing layer configurations and hyperparameter values used in CNNs can either create or resolve the issue of overfitting and affect final accuracy levels of object recognition systems. The main contribution …

Deep Semantic Hashing For Aerial Livestock Detection, Shosei Anegawa, Franz Kurfess, Sumona Mukhopadhyay

College of Engineering Summer Undergraduate Research Program

The goal of this project is to be able to accurately detect and count livestock in footage captured by a drone in real time. The main problems with this arise from the fact that a drone can only carry limited computing resources, and hashing is conventionally thought of as a great method of doing image classification very quickly and thus even on low-power devices. In this project, we use both a Faster-RCNN, which is a state-of-the art object detection model as a benchmark to develop a hashing model that can perform a similar task much more quickly. These two models …

Following this success, the team has constructed multiple drones and expanded their research to include applications in the fields of agriculture and ecology. This summer the goal is to use a iPhone 14 Pro in lieu of a traditional camera system for real-time object recognition. Object detection …

Industrial Jurisdiction, Daniel Z. Epstein

Dickinson Law Review (2017-Present)

William Novak’s New Democracy: The Creation of the Modern American State reveals how the current administrative state evolved to control economic activity through an incremental rejection of state-based common law and police powers in favor of centralized public regulation. This review identifies the business case for the administrative state and presents the first academic treatment of pro-regulation testimony from business interests during congressional consideration of the Interstate Commerce Act. In so doing, this review shows how the concept of industry is as much a legal concept as it is an economic one. This review argues that the nature of regulatory …
