dc.title: PEAK : cost-adaptive profiling in a heartbeat dc.description.abstract: Instrumentation-based profiling is essential for uncovering fine-grained optimization opportunities in High-Performance Computing (HPC) and cloud applications, yet static instrumentation methods often impose fixed profiling overheads that cannot adapt to the dynamic workloads from applications at runtime. We further …

dc.title: Asymmetric Ru-catalyzed carbonyl allylations via hydrogen transfer to π-unsaturated feedstocks : progress towards the synthesis of bafilomycin A₁ dc.description.abstract: Chemo-, regio-, and enantioselective C–C coupling of alcohols or aldehydes with unsaturated hydrocarbons to furnish chiral homoallylic alcohol products was achieved using iodide-bound ruthenium complexes that are stere…

dc.title: Design of low-loss acoustic delay lines on thin-film lithium niobate dc.description.abstract: As wireless systems continue moving toward higher frequencies and greater front-end complexity, compact low-loss signal-processing components become increasingly desirable. Acoustic delay lines are attractive in this context for their ability to process RF signals in the mechanical domain, wher…

dc.title: Performing authenticity on Instagram reels: mother influencers and the co-construction of authenticity in audience responses dc.description.abstract: This study examines how mother influencers perform authenticity on Instagram Reels and how audiences respond in comment sections. Using quantitative content analysis of 500 Reels and 4,612 comments, authenticity is conceptualized as observ…

dc.title: Toward high-performance compact RF acoustic filters in thin-film piezoelectric platforms dc.description.abstract: Continuing evolutions in mobile technologies have made wireless systems pervasive and tightly integrated into daily life. Such systems demand compact radio frequency (RF) front ends (FEs) capable of supporting ever-increasing data rates and functionalities within crowded spe…

dc.title: Exploring environment-sensitive fluorescent turn-on probes for Zn²⁺-containing metalloenzymes dc.description.abstract: Zinc is an essential micronutrient that is widely integrated into many cellular processes, serving structural, catalytic, and regulatory roles. In cells, it exists largely in two tightly regulated pools: labile and sequestered zinc. To date, most methods for studying ce…

dc.title: Bridging the creek: an evaluation of the 2019 Little Walnut Creek Greenbelt Community Master Plan and recommendations for implementation dc.description.abstract: The Little Walnut Creek Greenbelt is a 206-acre public park in East Austin, Texas, one of the largest greenbelts in the City of Austin Parks and Recreation Department's inventory. Despite its size and proximity to several resid…

dc.title: Peer cannabis vaping, social acceptability, and social motives as predictors of cannabis vaping among Texas college students dc.description.abstract: Cannabis vaping has emerged as a prevalent mode of consumption among college students, yet little is known about why young adults with more peers who use cannabis are at greater risk. Guided by Social Cognitive Theory (SCT), this study det…

dc.title: Development and validation of a precast column solution for Texas bridges dc.description.abstract: This dissertation examines a novel construction method utilizing Precast Prestressed Concrete Piles (PCP) filled with concrete cast-in-place, working as one complete column to evaluate their structural performance under varying levels of eccentricity, with the goal of introducing a new pr…

dc.title: Improved genetic tools and evolution-aware approaches for engineering honey bee gut symbionts dc.description.abstract: The Western honey bee (Apis mellifera) is an indispensable agricultural pollinator supporting a wide variety of food crops. Unfortunately, widespread use of pesticides, pathogens like deformed wing virus, and invasive pests including hive beetles, killer hornets, and Va…

dc.title: Dimensionality reduction of plantar pressure data using principal component analysis: optimal sensor configuration across 12 activities dc.description.abstract: Plantar pressure insoles generate unpractical and hard to manage dimensionality dataset, a single record at 65Hz produces over one million data points per 45 seconds recording session, constraining widespread clinical and athlet…

dc.title: Intersection theory on Hurwitz spaces of low-degree covers dc.description.abstract: We show that the first cohomology group of the Hurwitz space of fully-marked admissible covers H^1(H_{d,g}(μ)) vanishes for covers of degree d = 3 and deduce the same result for the classical Hurwitz space of simply-branched covers H^s_{3,g}. In degrees 4 and 5, we compute examples where H^1(H_{d,g}(μ)) …
