This Final Report outlines the development of a lower limb prosthetic docking and charging station to address a critical need for individuals with unilateral transfemoral amputations who use microprocessor-controlled prosthetics. This project is focused on designing and producing a secure, accessible, and aesthetically pleasing stand to store and charge prosthetic limbs overnight, targeting the lack of commercially available, functional prosthetic storage. The absence of a functional storage solution points to a failure in meaningfully addressing the human needs of prosthetics users, exacerbating user frustration through the perpetuation of issues including prosthetics falling over into inaccessible positions, and tripping hazards due …

Force Mapping Wand For Individuals With Upper-Limb Amputations, Max Bosse, Cole Capitani, Eddie Grassini

Biomedical Engineering

Technology relating to upper-limb amputations has seen many advances in recent years, especially in terms of function and aesthetic appeal. Although these improvements exist, comfort is often a primary concern among prosthetic users and can lead to prosthetic abandonment [1]. Without a standardized method of measuring force concentrations in patients, high rates of discomfort and potential tissue damage remain. The goal of this project is to create a force mapping system for upper-limb amputees to help minimize discomfort in socket fit during the fitting process using real-time data and software to view force concentrations. To accomplish this goal, background research …

A Developmental Texture Framework For Food Texture Progression: Implications For Feeding Development, Oral Motor Skills, And Pediatric Feeding Disorder, Amy L. Delaney, Sarah Staskiewicz, Suzanne Evans Morris, Sarah Smith-Simpson, Praveen S. Goday

Speech Pathology and Audiology Faculty Research and Publications

The introduction of food textures in a child's first 2 years of life plays a vital role in growth, nutrition, and feeding development. However, the absence of a standardized texture framework for studying texture progression limits both pediatric feeding research and the ability to diagnose pediatric feeding disorder (PFD) based on age-appropriate expectations. To address this gap, authors Delaney and Goday proposed data sharing from the Nestlé Feeding Infant-Toddler Study (FITS) to explore texture progression and define age-appropriate texture expectations. In response, Nestlé assembled a multidisciplinary panel of feeding experts to create standardized textures but did not provide financial or …

Summaries Of Arkansas Cotton Research 2024, Fred M. Bourland

Arkansas Agricultural Experiment Station Research Series

Planted cotton acreage in Arkansas increased in 2024 to 670,000 planted acres, which was 160,000 acres more than in 2023 when Arkansas producers planted approximately 510,000 acres of cotton. A wet spring, and two hurricanes in three weeks in late summer/early fall led to a slight decrease in harvested acres that culminated in a final number of 640,000 (https://www.nass.usda.gov/Quick_Stats/Ag_Overview/stateOverview.php?state=ARKANSAS). Producers harvested 640,00 acres of cotton, which ranked third nationally, behind Texas and Georgia (https://downloads.usda.library.cornell.edu/usda-esmis/files/k3569432s/nk324887m/qn59s0097/cropan25.pdf). The total harvested acreage is the greatest amount since 680,000 acres in 2011. The average cotton yield in Arkansas in 2024 was …

Glutamatergic Regulation Of Mirna-Containing Intraluminal Vesicle Trafficking And Extracellular Vesicle Secretion From Cortical Neurons, Marcela Bertolio, Qiyi Li, Francesca E Mowry, Kathryn E Reynolds, Rashed Alananzeh, Haichao Wei, Kyoeun Keum, Rachel Jarvis, Jiaqian Wu, Yongjie Yang

Faculty, Staff and Student Publications

Neuronal extracellular vesicles (microvesicles and exosomes) are emerging secreted vesicular signals that play important roles in the CNS. Currently, little is known about how glutamatergic signalling affects the subcellular localisation of exosome precursor intraluminal vesicles (ILVs), microRNA (miR) packaging into ILVs and in vivo spreading of neuronal EVs. By selectively labelling ILVs and exosomes (but not plasma membrane-derived MVs) with GFP-tagged human CD63 (hCD63-GFP) in cortical neurons, we found that glutamate stimulation significantly redistributes subcellular localisation of hCD63-GFP+ ILVs, especially decreasing its co-localisation with multi-vesicular body (MVB) marker Rab7 while substantially promoting EV secretion. Interestingly, glutamate stimulation only modestly alters …

Infrastructure From Below: Mediasi Dan Politik Pembangunan Infrastruktur Air Di Kota Balikpapan, Muhammad Althaf Nandiati Yusfid

Antropologi Indonesia

The city of Balikpapan is experiencing a water crisis. The discrepancy between the city's water supply and Balikpapan's demography put pressure towards the city's capability of supporting its own citizens. This issue is exacerbated by the development of Indonesia's New Capital (IKN) which is located just outside Balikpapan. Therefore, the development of water infrastructure is imperative for the city. Yet, there's no recent visible development of water infrastructure in the city. However, I argue that water infrastructure development actually exists, though in a subtle form. The informal water suppliers that are prevalent in the city is tied with how the …

Background: Pediatric liver tumors are predominantly primary malignant tumors, and complete tumor resection with sufficient preservation of liver tissue is crucial for improving prognosis. However, due to the delicate anatomical structure of the pediatric liver and the relatively large size of the tumors, especially in difficult cases, the surgical challenges are substantial. While precision liver surgery are widely applied in clinical practice, pediatric cases require more customized approaches. The application of three-dimensional (3D) visualization technology is crucial for enhancing surgical accuracy, allowing for precise preoperative planning and intraoperative guidance.

Methods: This consensus was collaboratively developed by 36 experts from eight …

From Human Mapping To Machine Embedding: Uncovering Key Legal Drivers And Deterrents Of Isds Filing Frequencies, Sangchul Park

Chicago Journal of International Law

International investment agreements (IIAs), while intended to prop cross-border investment, have faced persistent criticism for potentially undermining the regulatory sovereignty of developing countries. Various mechanisms have been proposed as alternatives to traditional bilateral investment treaty (BIT) models, often with the goal of curbing investor-state dispute settlement (ISDS) filings. While existing research has uncovered the impact of nonlegal factors, such as macroeconomic crises, little has been done to systematically examine how legal provisions in either major model BITs or ISDS reform toolboxes influence ISDS filing patterns. To address this gap, this Article analyzes the interplay between (i) legal texts of 2,148 …

Technology And The Law Of Jus Ante Bellum, Asaf Lubin

Chicago Journal of International Law

The temporal boundaries of the international rules governing military force are myopic. By focusing only on the initiation and conduct of war, the legal dichotomy between Jus Ad Bellum and Jus In Bello fails to address the critical role of peacetime military preparations in shaping future conflicts. Disruptive military technologies, such as artificial intelligence and cyber offensive capabilities, only further underscore this deficiency. During their pre-war development, these technologies embed countless design choices, hardcoding into their software and user interfaces policy rationales, legal interpretations, and value judgments. Once deployed in battle, these choices have the potential to precondition warfighters and …

The Reign Of Cerberus: International Law And Technological Innovation, Paul B. Stephan

Chicago Journal of International Law

This Essay sketches an informal theory of the impact of technological change on international economics, and hence international relations expressed as international law. The theory points to a policy trilemma, something that I call Cerberus in a perhaps futile attempt at an arresting metaphor. The Essay uses the trilemma to illuminate the general trends in technology policy we see playing out in China, Europe, and the United States. It argues that we have the privilege of witnessing an ongoing natural experiment in optimal technology regulation and legal policy, with no guarantee as to which approach will prevail.

Coral reefs are one of Earth’s most vital and threatened ecosystems. They protect coastlines, generate billions of dollars of tourism revenue, support valuable fisheries, and contribute to the development of vital medicines. Yet half of the world's coral reefs have been lost in the last 50 years, and 90% of remaining reefs are projected to die off by the middle of this century, mainly due to warming seas from climate change.

Despite these challenges there is reason for hope. Some coral reefs – such as in the northern Red Sea and Gulf of Aqaba – have demonstrated remarkable resilience to …

Two Terribles: A Day Without Space And Ai Enabled Synthetic Biological Weapons A Warning Order, James E. Baker

Chicago Journal of International Law

A day without space, a term used to describe the loss or destruction of America’s space assets, and the potential generation of novel biological threats using AI and synthetic biology present catastrophic and potentially existential threats to U.S. security in a way that nuclear weapons did before and continue to do so today. Yet they have not received the level of attention from national security lawyers or commentators they warrant. This article describes the threats. It describes the current and inchoate nature of the law to address these threats. And it makes initial recommendations to policymakers and lawyers about how …

Journal of Economics and Administrative Sciences

This paper deals with studying the relationship between internal and external gaps and the gross domestic product in Iraq for the period (2004-2022), as the Iraqi economy suffers from a financing problem, and this problem has resulted in a weak link between the economic sectors, high inflation rates, as well as the inability of the economic policies followed to achieve the required financing, so the research problem can be clarified by asking about the impact of internal and external gaps on the gross domestic product.  Inductive and quantitative approaches were adopted, which relied on the joint integration methodology to show …

Exposure To Different Motives Of Scientists Moderates Responses To Scientific Consensus: The Case Of Cultured Meat, Kimin Eom, Bryan Kwok Cheng Choy

Research Collection School of Social Sciences

This research examines how exposure to different motives of scientists affects the impact of scientific consensus on public attitudes toward cultured meat. While scientific consensus on the safety of cultured meat generally increased positive attitudes toward it, this effect depended on information about scientists’ motives. Exposure to information about scientists’ financial motives weakened the positive effect of scientific consensus because it undermined trust in scientists. Information about scientists’ prosocial motives did not influence the scientific consensus effect. These findings suggest that perceived motives can shift trust in experts, thereby affecting the influence of experts on public attitudes.
