Transfer Learning Neural Networks For Nuclear Forensic Image Morphology Using Image Splitting Techniques, Niko A. Petrocelli, Lee C. Lambert, Brett J. Borghetti, Abigail A. Bickley

Faculty Publications

Manual morphological analysis of actinide particles from scanning electron microscope (SEM) imagery is a critical component of nuclear forensics but is prone to significant inter-analyst variability. To address this challenge, this work develops and evaluates an automated classification method using deep learning. We introduce a methodology based on partitioning 1906 SEM images, representing 13 classes of uranium compounds, into smaller patches for analysis. Three convolutional neural network (CNN) architectures of increasing complexity were compared: a custom baseline CNN, a simple transfer learning model using ResNet50v1, and a complex model featuring hierarchical feature extraction and a spatial attention mechanism built upon …

Mandatory Cooperation Under International Law, Evan J. Criddle, Evan Fox-Decent

Faculty Publications

Humanity in the twenty-first century faces serious global challenges and crises, including pandemics, nuclear proliferation, violent extremism, refugee migration, and climate change. None of these calamities can be averted without robust international cooperation. Yet, national leaders often assume that because their states are sovereign under international law, they are free to opt in or out of international cooperation as they see fit. This book challenges conventional wisdom by showing that international law requires states to cooperate with one another to address matters of international concern – even in the absence of treaty-based obligations. Within the past several decades, requirements to …

Ecowas: The Little Human Rights Organization That Could, Thomas Kelley

Faculty Publications

Part I of this Article provides a detailed description of the origins of the Economic Community of West African States (ECOWAS). Part II describes its transformation from a sleepy trade bloc to a dynamic peace and security and human rights enforcement institution. Part III examines arguments about whether ECOWAS’s aggressive human rights enforcement is or is not legal under international law. Part IV summarizes developments in West Africa after ECOWAS created its robust peace and security and human rights enforcement architecture, concluding that, until the recent crisis in the Sahel States, it has been extremely effective despite the scant resources. …

This study proposes the application of a four dimensional framework of autonomy to a weapon swarm of high subsonic cruise missiles.

War, Wounds, And Strategy: Patient Movement Lessons From The World Wars For Great Power Competition, Phillip R. Jenkins

Faculty Publications

This thesis examines the evolution of the U.S. military's patient movement system during World War I and World War II to evaluate how well it may perform under the conditions of future large-scale combat operations. It asks whether the United States can move, treat, and sustain wounded personnel at the scale and pace required to preserve combat power in a prolonged, high-intensity conflict. Using detailed case studies of the Meuse-Argonne Offensive and the Battle of the Bulge, the analysis focuses on how transportation platforms, organizational structure, and standard operating procedures (SOPs) shaped patient movement under conditions of attrition, disruption, and …

Anchoring ‘Neo-Hahnian Outdoor Education’ In The Cold War Era: A History Of Character Building In The Outward Bound Movement, Jayson Seaman

Faculty Publications

The invitation to comment on a foundational early article from the JAEOL provided a welcome opportunity to engage with Andrew Brookes’s trilogy of ‘neo-Hahnian outdoor education’ critiques (Brookes, 2003a, 2003b, 2023). In this article, I approach outdoor education’s character building ideology by using archival and secondary sources to situate its evolution in four periods corresponding with major geopolitical and cultural movements: (1) 1941–1945 when Outward Bound (OB) was established; (2) 1946–1952 when Hahn exported OB from his perch at Gordonstoun; (3) 1953–1967 when OB expanded to the U.S. and replicated globally, and (4) 1968–1976 when human potentialism replaced muscular Christianity …

Analyzing Stability Of Estimates At Completion For Long Duration Development Efforts, Bradley Vuu, Jonathan D. Ritschel, Brandon M. Lucas, Edward D. White

Faculty Publications

Defense program managers utilize Earned Value Management (EVM) methodologies to measure, report, and predict the cost and schedule performance of their programs. Previous research conducted by Christensen (1996) and Kim et al. (2019) has shown varied results in the stability of EVM Estimates at Completion (EACs). Stability is defined as a 10% or less deviation from the final EAC at a specified percent completion point of the program. The Christensen (1996) and Kim et al. (2019) studies also noted that program-specific factors, such as phase, can impact the accuracy of EVM metrics. This study builds upon those works by assessing …

On Large Language Models In National Security Applications, William N. Caballero, Phillip R. Jenkins

Faculty Publications

The overwhelming success of GPT-4 in early 2023 highlighted the transformative potential of large language models (LLMs) across various sectors, including national security. This article explores the implications of LLM integration within national security contexts, analyzing their potential to revolutionize information processing, decision-making, and operational efficiency. Whereas LLMs offer substantial benefits, such as automating tasks and enhancing data analysis, they also pose significant risks, including hallucinations, data privacy concerns, and vulnerability to adversarial attacks. Through their coupling with decision-theoretic principles and Bayesian reasoning, LLMs can significantly improve decision-making processes within national security organizations. Namely, LLMs can facilitate the transition from …

The Importance Of Fauna-Mediated Sediment O2 Consumption In The Ngom Hypoxic Zone, Hannah Beck, Kanchan Maiti

Faculty Publications

The northern Gulf of Mexico (NGOM) coastal shelf adjacent to the Mississippi and Atchafalaya rivers system experiences strong seasonal hypoxia in the late summer and coupled physical-biological models suggest that hypoxia formation in the NGOM is sensitive to benthic biogeochemical processes. However, the processes driving sediment oxygen consumption and their relationship to bottom oxygen concentration remain enigmatic. This study for the first time concurrently measured in situ total oxygen uptake (TOU) and diffusive oxygen uptake (DOU) during two different hypoxia seasons. The relatively large DOU: TOU ratio of 0.33 ± 0.07 observed during this study suggests more significant benthic infauna …

The Military's Constitutional Role, Brenner M. Fissell

Faculty Publications

A basic principle of the American constitutional order is that civilian authority must be supreme over that of the military. The violation of this principle by the British was one of the grievances enumerated in the Declaration of Independence, and the Framers responded with a Constitution that made military rule impossible. But why is so-called “civilian control” of the military so important? This deep normative question has yet to be thoroughly answered by scholars, most of who assume it away as a given. This Article takes up that task, using contemporary political theory to defend the principle of civilian control. …

A Temperature Tipping Point In Hypoxic Zone Size, R. Eugene Turner, Nancy N. Rabalais, Cassandra N. Glaspie

Faculty Publications

Temperature increases will have ubiquitous effects on aquatic food webs, from microbes to consumers, and affect the quality and quantity of carbon flows within and between water layers. A decline in the biological pump moving carbon from surface to lower layers is anticipated. We reviewed 37 years of data on hypoxic zone size and water quality in the northern Gulf of Mexico to determine if air and bottom water temperature increases (0.5°C decade⁻¹) are significantly related to variations in its areal size. There was no significant decline in important river water quality in the 24 years since the …

Trends In Hot Carrier Distribution For Disordered Noble-Transition Metal Alloys, Eklavya Thareja, Kevin M. Mcpeak, Phillip T. Sprunger, Ilya Vekhter, William A. Shelton

Faculty Publications

We developed and tested an approach for predicting trends for efficient hot carrier generation among disordered metal alloys. We provide a simple argument for the importance of indirect transitions in the presence of disorder, thus justifying the use of joint density of states (JDOS)-like quantities for exploring these trends. We introduce a new JDOS-like quantity, JDOSK , which heuristically accounts for longer lifetimes of quasiparticles close to the Fermi energy. To demonstrate the efficacy of this new quantity, we apply it to the study of Cu50X50 where X = Ag, Au, Pd and Y50Pd50 where Y = Au, Ni. We …

A Model-Based Reverse System Engineering Methodology For Analyzing Complex Biological Systems With A Case Study In Glycolysis, Gerald L. Fudge, Emily Brown Reeves

Faculty Publications

We propose a model-based reverse systems engineering (MBRSE) methodology for biological systems that relies on requirements analysis in conjunction with model-based systems engineering (MBSE). The goal of this methodology is to better understand complex multiscale biological systems, discover knowledge gaps, and make testable predictions. The similarities between human-engineered and biological systems motivate this approach. Furthermore, traditional reductionist paradigms in biology have proven insufficient for understanding and accurately predicting complex biological systems, as opposed to systems engineering approaches that have proven effective in supporting the design and analysis of complex engineered systems spanning multiple spatiotemporal scales. We employ our MBRSE methodology …

Fascism: A Reading List With Notes, Michael F. Russo

Faculty Publications

Today, Fascism is on the rise around the world including, dismayingly, in the United States of America, threatening the rule of law, which is the basis of democracy. In the U. S. Donald Trump, the 2024 Republican nominee for president, has declared himself the standard bearer for authoritarian rule. If he wins, it is likely the United States will cease to be a democracy. If democracy is to survive, it is essential that citizens understand fascism, how it comes into existence, and what it does once it has taken root is essential. That is the reason for this reading list.

Putting Students In Their Place. The Role Of Placement Testing In Language Programs, Troy L. Cox, Matthew P. Wilcox

Faculty Publications

A perennial issue that nearly all language programs face with the arrival of new students is: where is the best place for each student to begin their course of study within our curricular structure given their current language abilities? When students have no previous language learning experience, the decision seems easy: place them in the beginning- level class. But when students have prior experience, deciding where they belong becomes more complicated given the wide range in the quality and quantity of previous exposure and the level of ability attained. Programmatic exigencies and resources may constrain student placement even further.

Recommended Separation Distances For 1.3 Ammunition And Explosives, Clint Guymon, Ming Liu, Josephine Covino

Faculty Publications

Separation Distances are used throughout the world to protect people and assets from the potential hazardous effects from propellants, explosives, and pyrotechnics. The current separation distances for Hazard Division (HD) 1.3 substances and articles used in the United States, in some cases, may not adequately protect against the effects from heat flux and debris when those substances and articles are ignited in a confined structure. Multiple tests in such a confined scenario with HD 1.3 substances have shown that the heat flux and debris hazards could result in injury at distances beyond the current specified explosives safety separation distance (ESSD). …

The Characteristics Of Successful Military It Projects: A Cross-Country Empirical Study, Helene Berg, Jonathan D. Ritschel

Faculty Publications

In the armed forces, successful digitalization is crucial to ensure effective operations. Much of the existing literature on project factors during the planning and execution phases of public IT projects do not focus specifically on military sector projects. Therefore, the paper aims to provide empirical insights into the characteristics of successful military IT projects. Data from such projects in NATO countries and agencies were collected through interviews and project documents. The findings relating to the main variable of interest, “delivery of client benefit,” supported previous findings on IT project performance. Medium-sized projects performed better than small and large projects, and …

A Case For An Independent Cyber Force, Ian C. Heffron, Mark Reith, James W. Dean

Faculty Publications

Although cyberspace is considered the newest warfighting domain, military analysts and scholars have opined the United States remains woefully behind its peers in cyberspace and have called for the creation of a separate cyber service component. Yet a cohesive and robust discussion on this topic has yet to emerge. This article proposes a general framework that builds on the Joint doctrine, organization, training, materiel, leadership and education, personnel, facilities, and policy (DOTMLPF-P) analysis to address questions of sufficiency and necessity. Such analysis reveals DoD cyber operations do not maximize the United States’ ability to fight a cyber war, especially when …

Domain Restriction Zones: An Evolution Of The Military Exclusion Zone, Cole M. Mooty, Robert A. Bettinger, Mark G. Reith

Faculty Publications

Since the early part of the twenty-first century, US adversaries have expanded their military capabilities within and their access to new warfighting domains. When faced with the growth of adversaries’ asymmetric capabilities, the means, tactics, and strategies previously used by the US military lose their proportional effectiveness. To avoid such degradation of capability, the operational concept of the military exclusion zone (MEZ) should be revised to suit the modern battlespace while also addressing the shifts in national policy that encourage diplomacy over military force. The concept and development of domain restriction zones (DRZs) increase the relevancy of traditional MEZs in …

Genome-Wide Association Study Identified Candidate Genes For Alkalinity Tolerance In Rice, Lovepreet Singh, Rajat Pruthi, Sandeep Chapagain, Prasanta K. Subudhi

Faculty Publications

Alkalinity stress is a major hindrance to enhancing rice production globally due to its damaging effect on plants’ growth and development compared with salinity stress. However, understanding of the physiological and molecular mechanisms of alkalinity tolerance is limited. Therefore, a panel of indica and japonica rice genotypes was evaluated for alkalinity tolerance at the seedling stage in a genome-wide association study to identify tolerant genotypes and candidate genes. Principal component analysis revealed that traits such as alkalinity tolerance score, shoot dry weight, and shoot fresh weight had the highest contribution to variations in tolerance, while shoot Na+ concentration, shoot Na+:K+ …

Utilizing The System Engineering Trade Study Analysis Method To Analyze Patient Aeromedical Evacuation, Sara Shaghaghi, Jeremy M. Slagley, Michael E. Miller, Gaiven Varshney

Faculty Publications

The US Air Force has gone through many aeromedical patient isolation transport system designs. The first designs were developed in response to the Ebola outbreak in 2014 and, more recently, the COVID-19 pandemic. The trade study analysis part of the system engineering design method was used to analyze the historic and current aeromedical patient contamination control transport systems. A trade study is a process that evaluates alternatives based upon various “-ilities”, such as reconfigurability, flexibility, durability, cost, and more, and performs a systematic analysis to aid designers in producing a ‘good’ design alternative given the large set of possible solutions. …

Contaminated or infected patients present a risk of cross-contamination for emergency responders, attending medical personnel and medical facilities as they enter a treatment facility. The controlled conditions of an aerosol test chamber are required to examine factors of contamination, decontamination, and cross-contamination. This study presents the design, construction, and a method for characterizing an aerosol test chamber for a full-sized manikin on a standard North Atlantic Treaty Organization litter. The methodology combined air velocity measurements, aerosol particle counts and size distributions, and computational fluid dynamics modeling to describe the chamber’s performance in three dimensions. This detailed characterization facilitates future experimental …

Sanctions And Consequences: Third-State Impacts And The Development Of International Law In The Shadow Of Unilateral Sanctions On Russia, Avidan Cover

Faculty Publications

In response to Russia’s invasion of Ukraine, NATO member states and their allies have imposed “unprecedented,” unilateral economic sanctions to hold Russia accountable, degrade its military capability, and limit its international financial access.1 From the outset, sanctioning states such as the United States have stated that they “designed these sanctions to maximize the long-term impact on Russia and to minimize the impact on [themselves and their] allies.”2 These sanctions on an economic power like Russia “have global economic effects far greater than anything seen before.”3 And there is concern that the unintended consequences of the sanctions will disproportionately harm developing …

Power Shift: The Return Of The Uniting For Peace Resolution, Michael P. Scharf

Faculty Publications

In 2022, the United States dusted off the 1950 Uniting for Peace Resolution in order to obtain General Assembly condemnation of the Russian invasion of Ukraine. This was the first time in three decades that the Security Council and General Assembly had utilized the Uniting for Peace mechanism – a process designed to end-run a Security Council veto. Together with the General Assembly’s creation of the international investigative mechanism for Syria in 2016 over Russia’s objection, the use of the Uniting for Peace process to condemn Russia’s aggression represented a shift in power away from the Security Council and to …

Policing Veterans: What The Veterans Affairs Police Can Illustrate About The Policing Of Disability In America, Zachary R.M. Outzen

Faculty Publications

The Department of Veterans Affairs Police (“VA Police”), a federal law enforcement agency tasked with law enforcement on Department of Veterans Affairs (VA) properties, has a shocking record of misconduct and brutality against veterans. Because the VA is the largest integrated healthcare system in the United States, the VA Police are primarily responsible for policing VA medical facilities. While issues facing the veteran community have largely been analyzed as separate from those facing the American public at large, VA medical facilities replicate broader socioeconomic trends in policing of vulnerable populations. Veterans receiving VA healthcare services are disproportionately likely to be …

Parametrized Topological Complexity Of Collision-Free Motion Planning In The Plane, Daniel C. Cohen, Michael Farber, Shmuel Weinberger

Faculty Publications

Parametrized motion planning algorithms have high degrees of universality and flexibility, as they are designed to work under a variety of external conditions, which are viewed as parameters and form part of the input of the underlying motion planning problem. In this paper, we analyze the parametrized motion planning problem for the motion of many distinct points in the plane, moving without collision and avoiding multiple distinct obstacles with a priori unknown positions. This complements our prior work Cohen et al. [3] (SIAM J. Appl. Algebra Geom. 5, 229–249), where parametrized motion planning algorithms were introduced, and the obstacle-avoiding collision-free …

Southwest Pacific Tropical Cyclone Development Classification Utilizing Machine Learning And Synoptic Composites, Rupsa Bhowmick, Jill C. Trepanier, Alex M. Haberlie

Faculty Publications

This study evaluates the ability of machine learning algorithms to classify tropical depressions (TDs) and tropical storms (TSs) in the western region of the southwest Pacific Ocean (SWPO). Decision rules are generated to predict the environment required for a depression to fully develop into a mature storm, and the most influential predictors in the classification decision are ranked. TD and TS are discriminated based on a maximum sustained wind speed threshold (≥17 ms−1). Various aerosol, thermodynamic, and dynamic parameters are extracted closest to the initiation point of each non-developing and developing sample. The covariates associated with each labelled sample are …

U.S. Foreign Relations Law From The Outside In, Ryan M. Scoville

Faculty Publications

Arguments in the field of U.S. foreign relations law typically proceed from the inside out: legal actors focus on internal (domestic) sources of authority to reach conclusions with significant external (international) implications. The text and structure of the Constitution, case law, legislative intent, assessments of institutional competency, and historical practice thus dominate debates about treaty-making, war powers, diplomatic authorities, and related matters. This tendency reflects generic assumptions about the proper modalities of legal analysis and helps to ensure that the law reflects national values.

Yet inside-out arguments overlook a critical fact: the practical merits of U.S. foreign relations law often …
