Evaluating OpenMP Offloading for Intra-Node Multi-GPU Programming Across NVIDIA, AMD, and Intel Architectures: A 3D Heat Transfer Case Study

Currently, many of the leading supercomputers are equipped with GPUs from manufacturers such as NVIDIA, AMD, or Intel, which provide substantial parallelism and high throughput. It is common for a single compute node to host multiple GPUs (typically four or more); we refer to thi...

Direct electrocaloric characterization of polyvinylidene fluoride-based co- and terpolymers over a wide temperature range

Polyvinylidene fluoride-based polymers have emerged as promising materials for flexible and portable electronics, attracting significant attention as alternatives to electrocaloric ceramics for more energy-efficient cooling. Although many studies report record-high electrocaloric...

LangBiTe: model-driven bias testing of text-to-text large language models

Large language models (LLMs) have rapidly gained popularity across a wide range of applications, from customer support to content generation and decision support systems. However, LLMs have also been found to exhibit social biases, reflecting and amplifying stereotypes and prejud...

The Credibility Cost of Scientists’ Political Expression on Social Media

Abstract Scientists are increasingly visible on social media, and much of what they post touches politically salient issues. Drawing on our recent work (Alabrese et al. 2024. “Politicized Scientists: Credibility Cost of Political Expression on Twitter.” CAGE Working Paper 735), w...

The Transition of Youth With Diabetes From Pediatric to Adult Diabetes Care Services: A Consensus Report of the Joint Working Group of the International Society for Pediatric and Adolescent Diabetes (ISPAD), the European Association for the Study of Diabetes (EASD), and the American Diabetes Association (ADA)

Young adulthood is a period of significant and unique physiological, psychological, sexual, and social upheaval. Related challenges can have an impact on effective diabetes self-management, with high rates of unplanned health care use recorded for many, and consequent increases i...

Nanoscale Rear‐Interface Architecture Enables 36.2 mA cm −2 Photocurrent in Ultrathin and Bifacial ACIGS Solar Cells Through Light Management

ABSTRACT Reducing the absorber thickness in thin‐film photovoltaics has a direct impact on low raw material consumption and high manufacturing throughput. However, it leads to low optical performance due to incomplete light absorption. In (Ag,Cu)(In,Ga)Se 2 (ACIGS)‐based technolo...

O-H kinetic isotope fractionation model to assess lunar polar water ice reserves & origin

Abstract O-H isotope signatures are essential for unravelling the lunar water cycle, pivotal for a sustainable water exploitation and management (SDG6) on the Moon, Earth and beyond, and for better understanding the Earth-Moon system’s history and the Earth’s cryosphere. Sublimat...

Chiral soft mode transition driven by strain in ferroelectric bubble domains

Abstract Chirality in solids is attracting growing attention as a potential ferroic order, yet virtually no paradigmatic example of a soft-mode achiral-to-chiral phase transition has been firmly established to date. Here we identify ferroelectric bubble domains as a model system...

Loss Analysis of Low Bandgap (Ag,Cu)(In,Ga)Se 2 Solar Cells for Tandem Applications

ABSTRACT Tandem solar cells can better harness the energy of the solar spectrum. Chalcopyrite solar cells have drawn attention, being the only highly efficient devices with a bandgap around 1.0 eV, suitable for bottom cells. In the quest for better efficiencies, we conduct a comp...

Heat‐to‐Electricity Conversion Using Barium Strontium Titanate Multilayer Capacitors

ABSTRACT Pyroelectric materials are attractive for converting heat into electricity, yet the best performance is obtained with lead‐containing ceramics, remaining a major environmental concern. Here, we address this problem by developing lead‐free barium strontium titanate multil...

eDNA metabarcoding provides scalable and continuous biodiversity monitoring across the tree of life

Abstract Environmental DNA (eDNA) metabarcoding has the potential to substantially expand our knowledge of global biodiversity beyond that provided by conventional approaches. However, the degree to which eDNA data provides real ecological insight, rather than primarily reflectin...

The Consequences of Promoting Data Literacy among Graduate Students

Abstract We study the impact of a data literacy program on graduate students’ skills and academic outcomes at a large Italian university. The program targets students expected to have weak quantitative skills and provides 120 h of training in data interpretation and processing al...

Assessment of degradation in Ion pair membrane high temperature PEM fuel cells using commercial and customized catalysts under varied operating conditions

High-temperature proton exchange membrane fuel cells (HT-PEMFCs) present considerable advantages, such as high energy efficiency and tolerance to fuel impurities; however, durability issues and catalyst costs remain major barriers to commercial adoption. This study systematically...
