Efficient Deep Neural Network Compression For Environmental Sound Classification On Microcontroller Units, Shan Chen, Na Meng, Haoyuan Li, Weiwei Fang

Turkish Journal of Electrical Engineering and Computer Sciences

Environmental sound classification (ESC) is one of the important research topics within the non-speech audio classification field. While deep neural networks (DNNs) have achieved significant advances in ESC recently, their high computational and memory demands render them highly unsuitable for direct deployment on resource-constrained Internet of Things (IoT) devices based on microcontroller units (MCUs). To address this challenge, we propose a novel DNN compression framework specifically designed for such devices. On the one hand, we leverage pruning techniques to significantly compress the large number of model parameters in DNNs. To reduce the accuracy loss that follows pruning, we propose a …

Ocean Temperatures Do Not Account For A Record-Setting Winter In The U.S. West, Matthew D. Laplante, Liping Deng, Luthiene Dalanhese, Shih-Yu Wang

Journalism and Communication Faculty Publications

The record-setting winter of 2022–2023 came as an answer to both figurative and literal prayers for political leaders, policy makers, and water managers reliant on snowpacks in the Upper Colorado River Basin, a vital source of water for tens of millions of people across the Western United States. But this “drought-busting” winter was not well-predicted, in part because while interannual patterns of tropical ocean temperatures have a well-known relationship to precipitation patterns across much of the American West, the Upper Colorado is part of a liminal region where these connections tend to be comparatively weak. Using historical sea surface temperature …

Parkinson's disease (PD) is a common neurodegenerative disorder with a significant risk proportion driven by genetics. While much progress has been made, most of the heritability remains unknown. This is in-part because previous genetic studies have focused on the contribution of single nucleotide variants. More complex forms of variation, such as structural variants and tandem repeats, are already associated with several synucleinopathies. However, because more sophisticated sequencing methods are usually required to detect these regions, little is understood regarding their contribution to PD. One example is a polymorphic CT-rich region in intron 4 of the SNCA gene. This haplotype has …

N-Myc And Stat Interactor Is An Endometriosis Suppressor, Yuri Park, Xiaoming Guan, Sang Jun Han

Faculty, Staff and Students Publications

In patients with endometriosis, refluxed endometrial fragments evade host immunosurveillance, developing into endometriotic lesions. However, the mechanisms underlying this evasion have not been fully elucidated. N-Myc and STAT Interactor (NMI) have been identified as key players in host immunosurveillance, including interferon (IFN)-induced cell death signaling pathways. NMI levels are markedly reduced in the stromal cells of human endometriotic lesions due to modulation by the Estrogen Receptor beta/Histone Deacetylase 8 axis. Knocking down NMI in immortalized human endometrial stromal cells (IHESCs) led to elevated RNA levels of genes involved in cell-to-cell adhesion and extracellular matrix signaling following IFNA treatment. Furthermore, NMI …

Enhancement Of Mechanical Properties Of Pcl/Pla/Dmso2 Composites For Bone Tissue Engineering, Kyung-Eun Min, Jae-Won Jang, Cheolhee Kim, Sung Yi

Mechanical and Materials Engineering Faculty Publications and Presentations

Bone tissue engineering shows potential for regenerating or replacing damaged bone tissues by utilizing biomaterials renowned for their biocompatibility and structural support capabilities. Among these biomaterials, polycaprolactone (PCL) and polylactic acid (PLA) have gained attention due to their biodegradability and versatile applications. However, challenges such as low degradation rates and poor mechanical properties limit their effectiveness. Dimethyl sulfone (DMSO₂) has emerged as a potential additive to address these limitations, offering benefits such as reduced viscosity, increased degradation time, and enhanced surface tension. In this study, we investigate tailored composites comprising PLA, PCL, and DMSO₂ to enhance mechanical …

Collective Attribution In Cyberspace: A Rebranded Version Of Attribution Does Not Make It More Effective, Dan Efrony

International Law Studies

The international community has been unsuccessful in establishing an effective legal framework for holding States accountable for cyber wrongdoing. Instead, official political attribution—collectively denouncing States for irresponsible conduct in cyberspace—has become a common substitute to encourage compliance with voluntary non-binding international norms. Since December 2017, the United States and United Kingdom, along with their closest allies, have embraced and implemented collective attributions and responses. They thereby seek to shape “rules of the road” for responsible State behavior in cyberspace and to enhance accountability and deterrence. However, these attributions rely primarily on the outcomes of American and British attribution processes that …

Damage Evolution And Ductile Fracture Of Commercially-Pure Titanium Sheets Subjected To Simple Tension And Cyclic Bending Under Tension, Nicholas Pitkin, Philip Noell, David T. Fullwood, Marko Knezevic

Faculty Publications

This paper describes a study into the evolution of damage in commercial-purity titanium (CP–Ti) sheets subjected to cyclic bending under tension (CBT) and uniaxial tension (simple tension, ST). Sections were taken from sheets that were strained to various levels under both methods and were imaged using X-ray computed tomography (XCT) to reveal insights into the size, density, and distribution of microvoids in the sheets. Digital image correlation (DIC) was also used to observe the surface strain of CBT and ST sheets during testing. These results showed that elongation to failure (ETF) for CBT deformation is about 2.5× higher than for …

Detection And Mitigation Of Misleading Pheromone Trails In Foraging Robot Swarms, Ryan Luna, Qi Lu

Computer Science Faculty Publications

This study addresses the overlooked aspect of security in swarm robotics by exploring the vulnerabilities of stigmergic communication in foraging robot swarms. More specifically, we study the swarm's susceptibility to attacks that introduce misleading pheromone trails. Simulated scenarios in which detractor robots lay misleading trails to deceive benign foraging robots effectively reduce the foraging performance of the swarm. We analyze the impact of the attack on the swarm and evaluate the reduction of foraging efficiency. We introduce a defense mechanism using distance-based clustering (DBSCAN) along with a cluster grouping method to isolate large batches of detractors early in the simulation. …

Tuning Pid Controller For Quadrotor Using Particle Swarm Optimization, Eric X. Rodriguez, Qi Lu

Computer Science Faculty Publications

Energy expenditure for quadrotor control has a likelihood of being costly given parameter-dependent controllers that are less than optimal. The cost can grow proportionally when applied to multiple quadrotors for tracking and collaborative navigation tasks. This research aims to establish a basic approach to tuning PID (Proportional-Integral-Derivative) parameters for a simulated quadrotor drone. A PID controller for autonomy provides a straightforward method for correcting robotic movement based on its current state. However, applying a PID system to a flight controller poses challenges with an inherently under-actuated system, which includes the likelihood of large overshoots and lengthy adjustment times. To address …

Rational Design Of Lignin-First Biorefineries Through Lignin Analysis And Deconstruction Modeling Tools, Aditya Ponukumati

McKelvey School of Engineering Graduate Student Theses & Dissertations

Lignocellulosic biomass is produced photosynthetically from atmospheric CO2 and is one of the few sources of renewable, reduced carbon that is generated on a scale comparable to demand for chemical commodities. For a sense of scale, the U.S. Energy Security and Independence Act targets the production of approximately 16 billion gallons per year of second-generation lignocellulosic biofuels by 2025. That production would generate approximately 62 million tons per year of dry lignin byproducts. The focus of this dissertation is on the valorization of these lignin components of biomass. Currently, lignin is either discarded or burned for local heat or electricity …

Computational Modelling And Design Of Antibodies: Benefits From Analysis Of Their Unique Structural Motifs, Katherine M. Mccoy

Dartmouth College Ph.D Dissertations

The complexes that antibodies make with their binding partners, or antigens, are especially valuable to be able to predict and modify due to their unique role in the immune system. Yet, they present significant challenges to computational methods of both modelling and design. Antibodies are unlike most other proteins in that they are composed of a scaffold region, which is a highly conserved structure that is largely the same between antibodies of the same class, and Complementary Determining Regions (CDRs), which are comprised of hypervariable loops that largely determine their binding motifs. Additionally, antibodies and their antigens do not co-evolve …

Imām Al-Baghawī (D. 516/1123): Tafsīr And Sunnism During The 11th-12th Centuries In Khurāsān, Nourhan Hassanein

Theses and Dissertations

A number of recent studies have focused on the intellectual trends and debates surrounding the formation of Sunnism in the 11-12th centuries. Academics have explored various currents within the intellectual and social context of Sunni Islam during the 11th-12th centuries. George Makdisi, Richard Bulliet, Jonathan Brown, Daphna Ephrat, Mohamed Eissa, and Ahmad Khan studied topics related to the educational system, the scholarly community, heresy and Sunni orthodoxy, legal studies, ḥadīth, and theology. However, the status of scholarship on works of tafsīr differs significantly. There are few studies concentrated on the classical period, such as works on the commentaries of al-Thaʿlabī …

Penetrating Posterior Urethral Injuries: Case Report And Management Strategies, Seyed Sajjad Tabei, Brandon Lippold, Wesley Baas, Gregory Murphy

2020-Current year OA Pubs

Penetrating posterior urethral trauma from gunshot wounds (GSW) is rare and requires prompt treatment to minimize complications. Data regarding the management of such cases is scarce in the literature and poorly addressed in the guidelines. Different management approaches exist, including urinary diversion with immediate versus delayed urethroplasty/fistula repair. We present our case series to add to our experience to the literature. Three patients aged 18-44 presented with ballistic posterior urethra injuries from GSW. Initial management involved urethral catheter placement, with one patient requiring operative placement of urethral and suprapubic catheters (SPTs). Complications included recurrent membranous stricture, urinary retention, rectourethral fistula, …

Gaze Preferences To Male Contrapposto And Non-Contrapposto Postures, Farid Pazhoohi, Oliver Lee Jacobs, Alan Kingstone

School of Psychology

Contrapposto, an asymmetrical twisting of the hips and shoulders, has historically been associated with beauty and aesthetics in art. While the impact of a female contrapposto posture on perception of attractiveness and visual attention has been studied, its effects on males remain understudied. The current research aims to explore whether contrapposto postures in men influence perceptions of attractiveness, dominance, masculinity, dynamism, and naturalness, as well as visual attention. Two eye-tracking studies were conducted, utilizing images of male models in contrapposto and upright poses. Despite differences in attributions, no significant differences were found in visual attention between the two poses in …

Endogenous Car T Cell Activation Signal-Based Dual Car Construct, Asmita Khaniya, Koramit Suppipat M.D., Supannikar Tawinwung Ph.D., Nattiya Hirankarn M.D., Ph.D.

Chulalongkorn Medical Journal

Background: Despite the notable success of chimeric receptor (CAR) T-cell therapy in treating hematological malignancies, many challenges limit its therapeutic effectiveness. To overcome antigen loss mediated disease relapses, strategies like dual antigen-targeted CAR constructs have been used. However, this strategyrequires robust promoters, to ensure sufficient CAR expression on the cell surface. Utilization of multiple promoters cause the constitutive and simultaneous expression of CARs which lead to issues with CAR T cell tonic signaling and exhaustion.

Objective: This study aimed to utilize the endogenous CAR T cell activation signals to explore the dual CAR T cell-based platform.

Methods: Using scFv …

Integrate To Win From Competition Through Conflict: Create A Joint Force Information Warfare Component Commander, Tam N. Pham, Walter A. Berbrick

Joint Force Quarterly

Τhroughout the history of warfare, militaries have sought advantages by conducting information warfare (IW) to affect the perception and behavior of adversaries. Advances in IW capabilities are increasing the reach, speed, and effectiveness by which individuals, organizations, and systems can collect, process, disseminate, or act on information—and deny adversaries the same. The United States is not the only power to recognize the importance of IW in achieving national objectives. Russia and China have made great strides in improving and employing their IW capabilities to offset U.S. joint (and allied combined) forces in competition and conflict. Russia’s and China’s ability to …

Five Truths For Foreign Area Officers, Michael L. Burgoyne, Albert “Jim” J. Marckwardt

Joint Force Quarterly

Colonel John Collins served in the U.S. Army through three wars and went on to be a revered military strategist and scholar. He founded the Warlord Loop, an organization of defense and security thinkers that remains active today. In 1987, Collins captured five “truths” regarding special operations forces. In so doing, Collins helped define the principles and attributes of special operations forces, which had been misunderstood by the larger conventional military. Foreign area officer (FAO) is another often misunderstood specialty in the military that would also benefit greatly from an exploration of its own truths. This is especially important given …

Winning In The Competition Continuum With Engineer Civic Assistance Projects, James M. Ward

Joint Force Quarterly

With a credible threat gap between the United States and competitor states shrinking, strategic dialogues increasingly emphasize competition to gain relative superiority prior to armed conflict.1 To frame the term competition, Joint Doctrine Note (JDN) 1-19, Competition Continuum, states, “Rather than a world either at peace or at war, the competition continuum describes a world of enduring competition conducted through a mixture of cooperation, competition below armed conflict, and armed conflict.”2 The JDN 1-19 perspective suggests that a state’s policies and objectives vary by its temporal position in the competition continuum.

Τhe Taj Mahal Guest House made a unique offer: Give us data, get beer.1 The Jalalabad, Afghanistan, café offered beer to anyone who brought video files, voice recordings, documents, and data dumps. The Taj shut down after Jalalabad became too hostile to outsiders, but not before its proprietors amassed extensive fine-grained data on local political and economic matters and supported projects that set up communications networks for local people. At least as important was the Taj’s role in facilitating informal personal relationships across government (foreign and local), commercial, humanitarian, and ordinary social networks. While not overtly a U.S.-led information operation, …
