Exploring The Translation Lookaside Buffer (Tlb) For Low-Level Task Differentiation And Classification, Cristian Agredo, Daniel F. Koranek, Christine M. Schubert, Jose A. Gutierrez Del Arroyo, Tor J. Langehaug, Scott R. Graham

Faculty Publications

The primary focus of modern Central Processing Unit (CPU) technologies is performance improvement, with security often considered a secondary concern. As a result, vulnerabilities within the system are overlooked. While significant research, both offensive and defensive, has been conducted on CPU caches, relatively little attention has been given to the Translation Lookaside Buffer (TLB) due to its perceived lack of data granularity. Prior studies have typically combined multiple Hardware Performance Counters (HPCs) or relied on timing analysis to extract meaningful insights. In contrast, this study introduces a novel methodology that leverages only TLB related HPCs for multi-task classification, without incorporating …

High Field Performance Of Si-Doped N-Aln Layers Grown Using Pulsed Mocvd, Abdullah Al Mamun Mazumder, Tariq Jamil, Mafruda Rahman, Muhammad Ali, Grigory Simin, Asif Khan

Faculty Publications

We report on the study of high-field performance of Si-doped n-AlN layers that were grown using a pulsed metalorganic chemical vapor deposition (PMOCVD) process. In the past we showed this pulsed doping approach to lead to doping efficiency superior to that in the conventional MOCVD process. Here using them as the drift layer for a quasi-vertical conduction Schottky barrier, we show their ability to withstand high reverse bias voltages and sustain an electrical field as high as 9.9 MV cm−1. Our study thus demonstrates the viability of the PMOCVD growth and doping approach to yield n-AlN layers suitable …

Generalised estimating equations were used to assess the relationship between HDP severity categories (gestational hypertension, preeclampsia …

Understanding The Effects Of Binder Dissolution Dynamics On The Chemistry And Performance Of Lithium–Sulfur Batteries, Saheed A. Lateef, John Chmiola, Fabio Albano, William E. Mustain, Golareh Jalilvand

Faculty Publications

Lithium–sulfur batteries (LSBs) are promising next-generation energy storage devices due to their higher theoretical specific energy and lower cost compared to conventional Lithium-ion batteries. However, their practical implementation has been hindered by severe performance degradation during extended cycling, primarily driven by shuttling of soluble sulfur discharge products (polysulfides) between the cathode and anode leading to capacity loss. In this work, we investigate the impact of selected binders and solvents, highlighting the effect of the dissolution process of the binder in solvent, on the structural properties and electrochemical performance of sulfur cathode. It is demonstrated for a variety of binders that …

Uncovering Multiscale Structure-Property Correlations Via Active Learning In Scanning Tunneling Microscopy, Ganesh Narasimha, Deja Kong, Paras Regmi, Rongying Jin, Zheng Gai, Rama Vasudevan, Maxim Ziatdinov

Faculty Publications

Atomic arrangements and local sub-structures fundamentally influence emergent material functionalities. These structures are conventionally probed using spatially resolved studies and the property correlations are deciphered by a researcher based on sequential explorations, thereby limiting the efficiency and scope. Here we demonstrate a multi-scale Bayesian deep-learning based framework that automatically correlates material structure with its electronic properties using scanning tunneling microscopy (STM) measurements in real-time. Its predictions are used to autonomously direct exploration toward regions of the sample that optimize a given material property. This method is deployed on a low-temperature ultra-high vacuum STM to understand the structure-property relationship in a …

Photo-Crosslinked Persistent Micelle Templates With Near Universal Solvent Compatibility, Coby S. Collins, Mengxue Zhang, Cj Strurgill, Christian X. Ruff, Bryce Melton, Morgan Stefik

Faculty Publications

The controlled preparation of porous nanomaterials from block polymer templates is important for diverse applications from energy devices to optical coatings and sorbents. The architectural dimensions determine the overall performance for many of these applications, however the independent control of these dimensions has remained limited to a narrow range of solvent conditions for kinetically trapped (“persistent”) micelle templates. Polymers with a photo-reactive chemistry are shown to enable cross-linked micelle templates that universally remain persistent under diverse solvent conditions. Specifically, poly(poly(ethylene glycol methacrylate))-b-poly(butyl methacrylate-co-coumarin methacrylate) (OBC) was prepared by RAFT polymerization and the resulting micelles were crosslinked …

Mitchell, Andrew Campbell, Xiaoying Lian, Michael Madden, Yuzhen Wang, Lauren E. Van De Wal, Thelma Zaw, Brandon N. Vanderveen, Rodney Tatum, E. Angela Murphy, Yan-Hua Chen, Daping Fang, Melissa Ellermann, Jie Li

Faculty Publications

Correlative studies have linked human gut microbes to specific health conditions. Alistipes is one such microbial genus negatively linked to inflammatory bowel disease (IBD). However, the protective role of Alistipes in IBD is understudied, and the underlying molecular mechanisms remain unknown. In this study, colonization of Il10-deficient mice with Alistipes timonensis DSM 27924 delays colitis development. Colonization does not significantly alter the gut microbiome composition, but instead shifts the host plasma lipidome, increasing phosphatidic acids while decreasing triglycerides. Outer membrane vesicles (OMVs) derived from Alistipes are detected in the plasma of colonized mice, carrying potentially immunomodulatory metabolites into the …

Symbiotic International Law: Combatting Uyghur Forced Labor, Preston Jordan Lim

Faculty Publications

Since 2017, the Chinese government has launched a campaign of repression against the Muslim Turkic minorities of Xinjiang, a region located in China’s Northwest. While most scholars have focused on the mass internment of Uyghurs and other minorities, this Article highlights an under-discussed aspect of China’s campaign: the construction of a sophisticated forced labor system. Minority forced labor supplies key sectors of the global economy—from the automotive to the energy sectors—and allows Chinese companies to outcompete foreign firms. The unprecedented scope and sophistication of what I term the “modern Xinjiang forced labor system” imperils the very future of the international …

Low-Cost, High-Performance Electrodes For Pgm-Free Aem Water Electrolyzers: Structural Optimization Of Nimo-Based Cathodes, Mahmoud Amirsalehi, Noor Ul Hassan, Venkata Sai Sriram Mosali, Ian Street, Marjanul Manjum, Saheed Adewale Lateef, Jasmine Bohannon, Sam Mckinney, Ashutosh G. Divekar, Paul A. Kohl, Mustain E. William

Faculty Publications

Water electrolysis technologies for hydrogen production are receiving significant attention due to a drastic reduction in the cost of renewable energy sources in recent years. Though traditional alkaline and proton exchange membrane water electrolyzers are receiving the most commercial attention, the anion exchange membrane water electrolyzer (AEMEL) has the potential to be much lower in cost. AEMELs have recently shown remarkable progress in terms of performance and durability. However, they are still mostly operated with expensive platinum group metal (PGM) catalysts on both the anode and cathode. To achieve low cost, either PGM-free or ultra-low loading PGM catalysts are needed. …

Perceptions Of Spirituality And Of God: A Psychological Qualitative Study, Christopher E. Peck, Timothy B. Smith, Jamila Mastny

Faculty Publications

The majority of people living in the U.S. report that spirituality is an important part of their life that is influential to their well-being. However, individuals vary widely in how they conceptualize spirituality, which often stems from and overlaps with their conceptualizations of God or so-called “God image”. Examination of people’s experiences of spirituality and conceptualization of God can enable psychologists to improve their understanding of individuals’ core personal experiences. This study evaluates both spirituality and God image, as well as the relationship between these two constructs, using qualitative hermeneutic analysis of interviews with 63 adults (51% women, 49% men, …

Prescribed Fire Leads A Pine Flatwoods Specialist Tree Frog To Seek Local Refugia, Ian Biazzo, Pedro F. Quintana-Ascencio

Faculty Publications

Pine savannas of the southeastern United States evolved with frequent low-intensity wildfires. Today, land managers use prescribed fires to restore this ecological process while also controlling vegetative fuel accumulation. Given the ubiquitous application of this management tool, studies should consider impacts on target and nontarget taxa in these systems. During fires, animal populations persist in the landscape when individuals emigrate to unburned areas or seek refugia within the burn zone; otherwise, they experience local extirpation. We examined the effect of prescribed fires on a pine flatwoods specialist frog, the pinewoods treefrog Dryophytes femoralis, in a frequently burned pine landscape. …

In promoting sustainable cities and societies, accelerating the shift from sustainable building design to sustainable building operations is essential. A persistent challenge lies in the absence of a unified, multidimensional metric that enables meaningful performance comparisons across buildings of similar types and functions, both regionally and globally. This study develops and demonstrates the operational sustainability index (OPSi)—a novel metric grounded in case study research that integrates indoor environmental quality (IEQ) and energy utility quality (EUQ). OPSi is applied to six buildings in three comparative cases: (1) LEED-certified and non-certified dormitories, (2) LEED-certified and non-certified event buildings, and (3) male- and …

Maximum-Likelihood Estimation Of Glandular Fraction For Mammography And Its Effect On Microcalcification Detection, Bryce J. Smith, Joyoni Dey, Lacey Medlock, David Solis, Krystal Kirby

Faculty Publications

Breast tissue is mainly a mixture of adipose and fibro-glandular tissue. Cancer risk and risk of undetected breast cancer increases with the amount of glandular tissue in the breast. Therefore, radiologists must report the total volume glandular fraction or a BI-RADS classification in screening and diagnostic mammography. In this work, a Maximum Likelihood algorithm accounting for count statistics and scatter is shown to estimate the pixel-wise glandular fraction from mammographic images. The pixel-wise glandular fraction provides information that helps localize dense tissue. The total volume glandular fraction can be calculated from pixel-wise glandular fraction. The algorithm was implemented for images …
