Over 400 V Field‐Plate Enhanced Vertical Diamond Schottky Diodes With Near‐Ideal Behavior and Over 2700 A/cm 2 Current Density

Vertical diamond Schottky barrier diodes with field‐plate edge termination were fabricated on 1.5 μm low‐doped () epilayers grown on heavily boron‐doped substrates. Devices with Schottky radii of 25–350 μm and FP lengths of 0–20 μm were systematically characterized. Temperature‐d...

Coupling between Adsorption, Structure, and Rheology in Short-Side-Chain PFSA Ionomer/Carbon Black Suspensions in N-Propanol/Water

Abstract The rheological behavior of proton exchange membrane fuel cell catalyst inks arises from the coupled structuring of carbon particles and perfluorosulfonic acid (PFSA) ionomer dispersions, both strongly influenced by solvent composition. Here, the microstructure, ionomer...

Radiative Transfer with Partially Frequency Coherent Scattering

We consider a spectral line formed with a linear combination of monochromatic scattering and complete frequency redistribution. A previous theoretical and numerical investigation by Hemsch and Ferziger in 1971 and 1972 suggests that a very small percentage of complete frequency r...

Beyond the standardization trap: A critical quantitative perspective on disabilities across transit and public spaces

In recent years, there has been renewed interest in the discrepancies between conceived and perceived accessibility. A particularly recurrent critique of accessibility as conceived through planning and measurement standards is that it tends to misjudge the actual difficulties exp...

Assessing port infrastructure criticality and vulnerability for climate adaptation planning: Insights from three European ports

Climate change is increasing the intensity and frequency of extreme weather events, directly threatening critical port infrastructure and the stability of global supply chains. Effective adaptation planning requires systematic tools capable of identifying the most critical and cl...

Combined prognostic value of age at onset and socioeconomic status for long-term survival in metastatic breast cancer

We investigated the combined long-term prognostic value of age at onset and socioeconomic status (SES) on breast cancer overall survival (OS) and metastasis-free survival (MFS) in a cohort of women with metastatic breast cancer. Age at onset was defined as the age at primary diag...

Elements on the move: How ungulate migration expands Alpine biogeochemical footprints

Through depositing waste products, animals influence the spatial distribution of elements across landscapes. Yet the relationship between animal movement and element distribution remains poorly characterized. We developed a spatially explicit agent-based model to test how migrato...

Shipping noise may trigger valve closure responses in exploited scallop beds of the Gulf of St. Lawrence

Shipping noise is a pervasive form of underwater noise pollution, yet its effects on benthic invertebrates remain poorly integrated into spatial risk assessments. The Atlantic sea scallop (Placopecten magellanicus), a benthic bivalve supporting the world's largest wild pectinid f...

Mesoporous PU/PEDOT:PSS Electrodes Reveal Population‐Level Stochastic Bioelectrical Dynamics in Marine Diatoms

ABSTRACT Understanding how microbial populations generate and modulate electrical signals remains a major technical challenge because extracellular ionic processes are inherently weak, spatially distributed and stochastic. Here, we introduce a mesoporous ultra‐low‐impedance PEDOT...

Kissing Number of Codes: A Survey

The kissing number of a code is the average number of pairs of codewords at minimum distance from each other. It has fundamental applications in determining code performance. Besides, a recent interest has arisen from the field of side-channel analysis of algorithms handling sens...

Mechanistic insights into Nrf2- and PARP1-mediated radioresistance of glioblastoma stem cells under photon, proton, and carbon ion irradiation: An in vitro study

Glioblastoma multiforme (GBM) exhibits strong resistance to radiotherapy, partly driven by glioblastoma stem-like cells (GSCs) with enhanced redox homeostasis and DNA repair capacity. This study evaluated whether targeting Nrf2-mediated antioxidant signaling and PARP1-dependent D...

EXPRESS: Keyboard Layout Facilitates Anagram Solving: Evidence for Embodied Effects of Typewriting.

Motor experience related to writing influences reading performance, from letter recognition to word recognition. In our study, we tested the hypothesis that knowledge of the keyboard layout associated to typing promotes the retrieval of the order of the sequence of letters compos...

Predicting grain growth in polycrystalline materials using deep learning time series models

Grain growth strongly influences the mechanical behavior of materials, making its prediction a key objective in microstructural engineering. In this study, several deep learning approaches are evaluated, including recurrent neural networks (RNN), long short-term memory (LSTM), te...

Ancient DNA reveals early use of melons in China’s Song dynasty

Abstract Melon ( Cucumis melo L.) domestication is thought to have occurred independently once in Northeast Africa and twice in India, but archaeobotanical seed remains point to a possible additional domestication in China. Because Cucumis seeds are difficult to diagnose morpholo...

Ubiquity and seasonality of deep submesoscales in the Southern Ocean revealed by elephant seals

Abstract Ocean submesoscale fronts with a size of 1–20 km have been extensively documented within the surface mixed layer, but little is known about their existence below it. We analyze a record of 133 598 dives performed by instrumented Southern Elephant Seals from 2014 to 2020...

Functional niche partitioning influences species turnover across supraglacial microbial communities on the Longxiazai glacier, Tibetan Plateau

Glaciers represent unique ecosystems harboring diverse microbial communities that dominate biomass and drive biogeochemical cycling across supraglacial habitats. These microbes transform deposited modern and ancient carbon/nitrogen, and these elements are subsequently transferred...

Valorization of Beach-Cast Biomass from the Invasive Seaweed Rugulopteryx okamurae on the Moroccan Coast: A Comparative Assessment of Extraction Conditions for Sodium Alginate Recovery

Rugulopteryx okamurae is an aggressively invasive seaweed whose proliferation along the Moroccan coastline represents both an ecological problem and an underexploited source of biomass. This work highlights the isolation of sodium alginate from R. okamurae under four combinations...

Experimental constraints on pre-eruptive conditions at Nabro volcano, Eritrea, 2011, and implications for sulphur emissions

Abstract We present new experimental constraints on the pre-eruptive magma storage conditions at Nabro Volcano, Eritrea, prior to its 2011 eruption, and discuss the implications for sulphur emissions. We find that the magma was likely stored in the shallow crust prior to eruption...

Programming Transition‐Metal Reactivity With Dicationic Tetrylene Z‐Type Ligands

ABSTRACT Dicationic tetrylenes possess unique σ–acceptor properties but have long remained chemical curiosities because of their intrinsic instability and limited coordination chemistry. Chen and Zhang now transform these elusive species into practical, electronically programmabl...

Stereoselective trans -1,4 Polymerization of Isoprene and β -Myrcene Mediated by Iron Complexes Bearing 1,1-Diaryl- N -(quinolin-8-yl)methanimine Ligands

Abstract Although iron has emerged as an earth-abundant alternative for 1,3-diene coordinative polymerization, stereoselective iron systems remain uncommon and are often associated with limited catalytic activity. Here, we report three iron(II) complexes supported by 1,1-diaryl-N...
