Changing fire regimes have important implications for biodiversity and challenge traditional conservation approaches that rely on historical conditions as proxies for ecological integrity. This historical-centric approach becomes increasingly tenuous under climate change, necessitating direct tests of environmental impacts on biodiversity. At the same time, widespread departures from historical fire regimes have limited the ability to sample diverse fire histories. We examined 2 areas in California's Sierra Nevada (USA) with active fire regimes to study the responses of bird, plant, and bat communities to a broad spectrum of temporal, spatial, and severity patterns of fire. Bird and plant species richness peaked …

Advancements in robotic systems aimed at improving mobility for individuals with disabilities have required more sophisticated control and navigation methods. Traditional control approaches often lack the complexity and adaptability needed for the high-dimensional nature of human activities. Consequently, reinforcement learning (RL) has emerged as a dynamic and effective framework for managing robotic actions in complex and unpredictable human environments. This article reviews the integration of RL in robotic systems for enhancing the mobility of individuals with disabilities, addressing the limitations of traditional control methods in complex and unpredictable environments. We critically analyze various RL algorithms, discussing their advantages and challenges …

Aggregation of microtubule-associated protein tau into conformationally distinct fibrils underpins neurodegenerative tauopathies. Fluorescent probes (fluoroprobes) such as thioflavin T have been essential tools for studying tau aggregation; however, most of them do not discriminate between amyloid fibril conformations (polymorphs). This gap is due, in part, to a lack of high-throughput methods for screening large, diverse chemical collections. Here we leverage advances in protein-adaptive differential scanning fluorimetry to screen the Aurora collection of 300+ fluoroprobes against multiple synthetic fibril polymorphs, including those formed from tau, α-synuclein and islet amyloid polypeptide. This screen—coupled with excitation-multiplexed bright-emission recording (EMBER) imaging and orthogonal secondary …


Barriers And Facilitators To Implementing A Single-Visit, Screen-And-Treat Approach With Thermal Ablation For Cervical Cancer Prevention In Kenya, Harriet Fridah Adhiambo, Thomas Odeny, Et Al. Jan 2025

Barriers And Facilitators To Implementing A Single-Visit, Screen-And-Treat Approach With Thermal Ablation For Cervical Cancer Prevention In Kenya, Harriet Fridah Adhiambo, Thomas Odeny, Et Al.

2020-Current year OA Pubs

Cervical cancer continues to be a major global threat to women's health, with approximately 660,000 women diagnosed annually, 94% of whom are in low- and middle-income countries (LMICs). The high disease burden in LMICs is partly due to suboptimal adoption and widespread implementation of effective preventive interventions. This study explored drivers of implementation success and failure for a future single-visit, screen, and treat approach with thermal ablation (SV-SAT + TA), referred to as TIBA in Kenya. Guided by the Consolidated Framework for Implementation Research (CFIR framework), we conducted in-depth interviews with 34 participants (frontline health workers, health facility managers, and …

Species distribution models (SDMs) have been developed for multiple cetacean species within the California Current Ecosystem (CCE) from shipboard survey data collected by the Southwest Fisheries Science Center (SWFSC) in summer and fall, thus limiting the ability to inform management decisions in cool seasons when abundance and distribution patterns are substantially different. Winter and spring SDMs have been developed for a few species using California Cooperative Oceanic Fisheries Investigations (CalCOFI) shipboard survey data, but model predictions are limited to the waters off southern and central California. In this study, winter and spring density estimates for the entire CCE study area …


Why Do Some Ultra Diffuse Galaxies Have Rich Globular Cluster Systems?, Duncan A. Forbes, Maria Luisa Buzzo, Anna Ferre-Mateu, Aaron J. Romanowsky, Jonah Gannon, Jean P. Brodie, Michelle L.M. Collins Jan 2025

Some ultra diffuse galaxies (UDGs) reveal many more globular clusters (GCs) than classical dwarf galaxies of the same stellar mass. These UDGs, with a mass in their GC system () approaching 10 per cent of their host galaxy stellar mass (), are also inferred to have high halo mass to stellar mass ratios (). They have been dubbed Failed Galaxies. It is unknown what role high GC formation efficiencies and/or low destruction rates play in determining the high ratios of some UDGs. Here we present a simple model, which is informed by recent JWST observations of lensed galaxies and by …

Improving Outcomes Of Single-Sided Deaf Cochlear Implant Users By Reducing Interaural Frequency And Loudness Mismatches Through Device Programming, Laura K Holden, Rosalie M Uchanski, Noël Y Dwyer, Ruth M Reeder, Timothy A Holden, Jill B Firszt Jan 2025

Improving Outcomes Of Single-Sided Deaf Cochlear Implant Users By Reducing Interaural Frequency And Loudness Mismatches Through Device Programming, Laura K Holden, Rosalie M Uchanski, Noël Y Dwyer, Ruth M Reeder, Timothy A Holden, Jill B Firszt

2020-Current year OA Pubs

The study aimed to improve outcomes in Nucleus cochlear implant (CI) recipients with single-sided deafness (SSD) by reducing interaural frequency and loudness mismatches through device programming. In Experiment 1a, a modified frequency allocation table (FAT) was created to better match the tonotopicity of the contralateral ear and reduce interaural frequency mismatch. Twenty experienced SSD-CI users completed localization and speech recognition tests with their everyday FAT. Tests were repeated after 6 weeks' use of the modified FAT. Participants compared both FATs for 2 weeks before being tested again with each. For 10 newly implanted SSD-CI recipients (Experiment 1b), Group A was …


Reconceptualizing Incomplete Attempt, Youngjae Lee Jan 2025

Reconceptualizing Incomplete Attempt, Youngjae Lee

Faculty Scholarship

Incomplete attempt laws are typically explained as laws that exist to justify timely law enforcement intervention. Such explanations may well provide good reasons for the laws based on harm prevention rationales, but they do not address the question whether a person who has, say, “cocked and aimed the pistol” has actually attempted to kill and is blameworthy for having done so. It turns out that this question is notoriously difficult to answer. This Article describes the challenge of defining incomplete attempt and of identifying and articulating its wrongfulness as a general theoretical matter. This Article then argues in favor of …
