Nudged elastic membranes for constructing reduced two-dimensional potential energy surfaces

Minimum-energy paths and intrinsic reaction coordinates are central tools for analyzing chemical reactions. As one-dimensional objects, however, individual paths do not provide a continuous representation of the surrounding potential energy surface (PES), including the arrangemen...

Where the World Connects: How Intergroup Contact on Social Media Influences Intergroup Outcomes

This study examines how, following the U.S. TikTok ban and the subsequent digital migration of foreign users to the Chinese social media platform RedNote, mediated intergroup contact with American users shaped intergroup outcomes among Chinese users. Guided by intergroup contact...

Nanoparticle Surface Curvature Impacts the Synthesis of Polymer Brushes

Abstract Surface-initiated ring-opening metathesis polymerization (SI-ROMP) is a powerful method for grafting polymers with different macromolecular architectures and chemical compositions onto surfaces, offering the potential to design hybrid materials with tailored properties....

Seismic behavior of circular steel tube confined reinforced concrete column-steel beam frames considering the joint effect

Reliable beam-column joints and rational design methods are crucial to ensure the safety and economy of frames, particularly for steel-concrete composite structures. This study numerically investigates the seismic behavior of the frame consisting of circular steel tube confined r...

Spatial transformations, placemaking strategies, and challenges of home-based rural E-commerce in Dinglou Village, China

Despite the transformative potential of digital economies in rural areas, household participation in rural E-commerce in China remains largely invisible and marginalized in development and spatial planning discourse, primarily due to an insufficient understanding of its socio-spa...

Point/Counterpoint on the Controversial 2025–2030 Dietary Guidelines for Americans

The 2025-2030 Dietary Guidelines for Americans (DGAs) issued nutrition recommendations, some of which have been praised by the nutrition community while others have been questioned based on the lack of supporting evidence. The recommendations about calorie control, emphasis on nu...

Legal status, gender, and the division of household labour among African couples

Legal status is a pivotal axis of stratification in the United States. Yet individuals do not migrate alone. Two-thirds of migrants are married, and migrant spouses receive a separate – and often dependent – legal categorization from that of their husband or wife. International s...

High-gain broadband circularly polarized antenna using microwave lens and metasurface for 5G millimeter-wave applications

This paper presents a new approach for designing a broadband, high-gain circularly polarized antenna for operation in the 5G millimeter-wave frequency bands. Initially, a microstrip patch antenna is designed on a Rogers RT/ Duroid 5880 substrate, employing a diagonally oriented p...

Information framing and the impact of nutrition label serving size change

Abstract The framing of information can significantly influence how consumers interpret and respond to it. This paper investigates how the change in serving sizes in Nutrition Facts Panel (NFP) affects consumer choices for carbonated soft drinks (CSD). We first estimate a reduced...

Data-driven Modeling of Telluric Features and Stellar Variability with StellarSpectraObservationFitting.jl

Abstract A significant barrier to achieving the radial velocity (RV) measurement accuracy and precision required to characterize terrestrial mass exoplanets is the existence of time-variable features in the measured spectra, from both telluric absorption and stellar variability,...

pynucastro 3: A community library for nuclear astrophysics

We describe the latest release of pynucastro: a community python library for nuclear astrophysics. The goal of the pynucastro project is to build the tools needed to interactively explore nuclear properties, reaction rates, and networks, and to export these networks to a variety...

Broadband Near-Field Imaging of Strong Polariton Coupling in Graphene/CrI3 Heterostructures

Abstract Interfacial charge transfer in van der Waals heterostructures provides a powerful, contact-free mechanism to activate two-dimensional plasmons. Chromium iodide (CrI3), a layered ferromagnetic insulator, induces significant doping in adjacent graphene, yet its nanoscale p...

Why Anthropologists Should Study Dogs

While primates have traditionally been a focus of evolutionary anthropologists, the domestic dog represents a valuable complementary model due to its long shared evolutionary history with humans. The advantages of studying dogs are particularly evident in four key areas: (1) anal...

Experimental manipulation of ecological constraints influences conflict but not cooperation in the humbug damselfish Dascyllus aruanus

Animal societies vary widely in levels of cooperation and conflict, and understanding the causes of this variation is a central goal in evolutionary biology. As with other features of animal societies, relatedness, competitiveness and ecological constraints (e.g. habitat saturati...

“New Way to Look at Shared Problems”: Team Science in Special Education Research

In special education, the complexity of serving individuals with disabilities and their families necessitates sustained interdisciplinary collaboration. However, little is known about how the principles of team science are valued and enacted within higher education programs that...

Der Haus : Evidence of Change in Gender and Number Agreement in One Pennsylvania Dutch Variety

Abstract This article investigates gender and number agreement on definite articles, adjectives, and pronouns in one Pennsylvania Dutch variety spoken by the Amish of Lancaster County, Pennsylvania. The findings, based on eight speakers, suggest that the nominal system in this va...

Fare sensitivity at point zero: How fare-free transit riders react to fare reinstatement and service changes?

Abstract Transit users are considered insensitive to fare changes. Therefore, reducing fares is often viewed as ineffective for increasing ridership. However, removing fares has led to markedly different outcomes in practice. Fare-free transit (FFT) policies have resulted in subs...

Physics-Informed Deep-Operator Learning for Computational Hydraulics Modeling

Abstract Traditional two-dimensional (2D) hydraulic models face significant computational challenges (e.g., long computing times) that limit their use in applications that are time-sensitive or require many model evaluations. This study presents a physics-informed deep-operator n...

Progress toward a Better BOCS: Systematic Coarse-Graining with Local Density Potentials

Abstract We introduce version 5.0 of the bottom-up open-source coarse-graining software (BOCS) package. BOCS employs the force-matching variational principle to parametrize potentials for coarse-grained (CG) models directly from atomically detailed simulations. BOCS version 5.0 s...

Interrupted Time Series Analysis of the Efficacy of Bilingual Abstract Semantic Associative Network Training

Purpose: In response to the need for more appropriate anomia treatment materials for bilingual persons with aphasia (BPWAs), we have created linguistically and culturally appropriate versions of AbSANT (Abstract Semantic Associative Network Training) for several languages that we...
