Dormancy type, seed traits, and species identity shape seed‐associated fungal community composition in tropical pioneer trees

Seed germination is regulated in many plants by seed dormancy, while postdispersal survival is often determined by soilborne fungi that infect seeds. In tropical forests, seeds in each of three dormancy types (physical, physiologically dormant, or quiescent) often share similar p...

Mass Addition Processes in Compressible Flows

The fundamental gas dynamic and thermodynamic effects of simple mass addition in compressible flows are examined. While the driving influences of heat addition and friction in constant area ducts are well understood and commonly taught, relatively little attention is given to the...

A Copula-Based Joint Model for Speed and Accuracy

This study proposes a copula-based model that relaxes the multivariate normality assumption among latent traits in the joint modeling of multimodal data, such as item response and response times. In the structural model, the joint distribution of latent traits is defined via a co...

Interlayer Bonding through Olefin Metathesis in 3D-Printed Poly(dicyclopentadiene) Thermosets

Abstract The direct ink writing (DIW) of thermosetting polymers is fundamentally constrained by weak interlayer bonding, leading to mechanical anisotropy and limiting their use in structural applications. Existing strategies to mitigate this challenge typically rely on thermal po...

Infant hippocampal and amygdala volume in an observational follow-up from a randomized clinical trial for maternal prenatal depression

Abstract Prenatal maternal depression may have intergenerational effects on offspring brain development, with potential socioemotional consequences. This observational follow-up study examines brain development and subsequent negative emotionality among 109 infants born to mother...

How social status shapes U.S. children’s beliefs about social mobility

Children grow up within social hierarchies that shape their everyday lives. Social mobility is a core mechanism through which societies either challenge or maintain existing inequalities. The present study examined how U.S. children’s social status—both experimentally manipulated...

Humans in the Loop: Privacy-Focused AI Solutions for Digital Collections Alt-Text

Librarians collaborated to develop a workflow that utilized a local AI model to retrieve, scan, and create initial alt-text for all repository images to meet ADA Web Content Accessibility Guidelines 2.1 at the University of South Florida Libraries with a focus on privacy and ethi...

Benchmarking deep learning-based reconstruction methods for photoacoustic computed tomography with clinically relevant synthetic datasets

Deep learning (DL)-based image reconstruction methods for photoacoustic computed tomography (PACT) have developed rapidly in recent years. However, most existing methods have not employed standardized datasets, and their evaluations rely on traditional image quality (IQ) metrics...

A self-adaptive tube restraint for free-energy calculations along path collective variables

Path collective variables reduce a high-dimensional transition to a progress coordinate, s, and an orthogonal distance, z. Computing the free energy along s often requires restraining z, so that sampling embraces a tube centered on the reference path. However, a conventional fixe...

Unmanned aerial vehicle time‐series phenotyping illuminates genotype‐specific responses to off‐target dicamba exposure in soybean

Abstract Dicamba, a synthetic auxin herbicide, is widely used for postemergence weed control. However, the high potential for volatility and spray drift raises concerns about damage to nontarget dicot crops lacking the dicamba monooxygenase transgene, which provides bioengineered...

Consumer welfare effects of banning hemp-derived THC beverages

Abstract A recent federal policy will close a regulatory loophole created by the 2018 Farm Bill and restrict the sale of intoxicating hemp-derived tetrahydrocannabinol (THC) beverages in the United States. Given the sector’s popularity among U.S. adults, it is useful to quantify...

Delayed Neutron Precursor Data Uncertainty and Sensitivities in Microscopic Calculations

This paper presents an analysis of the uncertainty-weighted sensitivities of the delayed neutron precursor (DNP) group parameters, consisting of half-lives τk and yields νd,k, with their nuclear data. This analysis was conducted using the thermal fission of 235U from various data...

Local approximations of global Hamiltonian from inclusion of algebras

A bstract We write down the global Hamiltonian of conformal field theory (CFT) in finite volume in terms of the modular Hamiltonian of the vacuum reduced to a local ball-shaped region, and use it to propose local approximations to the global Minkowski Hamiltonian in quantum field...

Evidentiary Interpretation, Discursive Injustice, and Rap on Trial

ABSTRACT The submission of rap lyrics as inculpatory evidence (Rap on Trial) is an active prosecution tactic deployed in United States criminal trials. In this paper, I argue that interpretive ambiguity in rap lyrics is exploited in Rap on Trial cases, constituting a novel form o...

Deciphering Interheme Electron-Transfer Pathways in a Diheme Peroxidase from Methane-Oxidizing Bacteria

Abstract Bis-FeIV-forming enzymes represent an emerging paradigm in high-valent heme iron chemistry, in which two hemes separated by 15–20 Å are both oxidized to the FeIV state. A tryptophan positioned between the two hemes in two out of the three known enzymes to form this state...

Festival infrastructure: The ritual dimension of community development in southwestern Ghana

This article reconceptualizes festivals as infrastructures of governance, focusing on the Kundum and Mother River festivals in southwestern Ghana. Drawing on longitudinal ethnographic fieldwork, it demonstrates how these festivals function as systems that coordinate collective ac...

Millimeter-Scale, Atomically Controlled 2D Topological Insulators Revealed by Multimodal Spectroscopy

Abstract Quantum spin Hall insulators, also known as 2D topological insulators, are crucial 2D systems hosting topologically protected edge states. The working temperature of this topological quantum phase is dictated by the inverted bandgap. However, the previously identified la...

Technology to remotely capture key elements of swallowing and speech: State of the science in Parkinson's disease

Swallowing and speech impairments are common in Parkinson's disease (PD) and can significantly affect health and quality of life. Traditional methods for assessing and managing these functions rely on in-person visits and large, expensive equipment, which are inaccessible to many...

Tuning the Architecture of High-Density Bottlebrush Block Copolymers to Control Their Photonic Properties

Abstract The backbone rigidity of bottlebrush block copolymers (BBCPs) induced by the dense branches distributed along their polymeric backbones has made them materials of interest for fast self-assembly of photonic materials. Today, the rigidity of BBCPs is limited by the maximu...

Single‐Crystal Helical Covalent Polymers with Organic Counter Cations

ABSTRACT Helical polymers, central to many bioactive molecules and polymers, offer distinctive functional properties, yet the precise synthesis and atomic‐level characterization of artificial helical covalent polymers (HCPs) remain challenging. Here, we demonstrate that soft orga...
