Precise Nanoscale Mapping of Electric Fields Across Random Grain Boundaries in Polycrystalline Oxides Using Precession‐Assisted 4D‐STEM

ABSTRACT Space charge layers (SCLs) at grain boundaries play a crucial role in modulating electric fields and thereby influence functional properties of materials. However, experimental analysis of these localized electric fields and the corresponding charge distribution remains...

Supporting AI Readiness Through Digital Workflows in Materials Science

Materials science produces heterogeneous data across experiments, simulations, and industrial processes that often remain bound to local formats, manual procedures, and project‐specific software. Digital workflows address this fragmentation through explicit, repeatable, and machi...

Uncertainties of GRACE/GRACE-FO Satellite Gravimetry Data and Thereof Derived Products

Abstract Inter-satellite ranging by space gravimetry missions, such as from the Gravity Recovery And Climate Experiment (GRACE) mission and its successor mission GRACE Follow-On, has been established to observe mass variations in the Earth system from space globally. A complex pr...

State-of-the-art electroweak Higgs boson pair production in association with two jets at the LHC in the Standard Model and beyond

We present a systematic comparison of two state-of-the-art tools for the simulation of Higgs boson pair production via vector boson fusion (VBF) as implemented in the Monte- Carlo tools GoSam+Whizard and the POWHEG-BOX. The comparison is carried out at LO and NLO-QCD in the SM an...

Competitive Anion Coordination Modulates Anode Interfacial Chemistry for Wide‐Temperature Sodium Batteries

ABSTRACT Sodium‐ion batteries (SIBs) offer a promising, cost‐effective alternative for large‐scale energy storage due to the abundance of sodium. However, their practical deployment is challenged by sluggish interfacial kinetics and unstable interphase formation, which severely l...

PHOBIC: Perfect Hashing with Optimized Bucket Sizes and Interleaved Coding

A minimal perfect hash function (or MPHF) maps a set of \(n\) keys to \([n]:=\{1,\ldots,n\}\) without collisions. Such functions find widespread application e.g. in bioinformatics and databases. In this paper we revisit PTHash – a construction technique particularly designed for...

Green space exposure predicts manic episodes in bipolar disorder: one year longitudinal analysis using smartphone-derived GPS data

Abstract Urban living is linked to increased psychiatric morbidity, while green spaces may protect mental health via stress-buffering effects. Yet, the role of green space exposure in the onset of affective episodes in bipolar disorder (BD) remains unclear. Using 12 months of GPS...

Programmable Carrier‐Free All‐Enzyme Beads for Modular Continuous‐Flow Biocatalysis

Carrier-free enzyme materials offer maximal catalytic density but are typically limited to monolithic or amorphous architectures with restricted process compatibility. Here, we introduce programmable carrier-free all-enzyme beads as structurally defined, porous biocatalytic parti...

A Current Distribution Mechanism Study Between an SiC MOSFET Body Diode and a Paralleled SiC Schottky Barrier Diode During Freewheeling

Paralleling an external SiC Schottky barrier diode (SBD) with an SiC MOSFET redistributes the reverse-conduction current and may reduce the reverse-recovery energy. However, the benefit depends on device selection and operating conditions, and an unsuitable SBD can increase the r...

13C and 19F nucleus–electron correlation and self-energies

We present a theoretical and numerical study of the correlation between electrons and the fermionic 13C and 19F nuclei. We use the random-phase approximation (RPA) as a valuable tool in obtaining these correlation energies. A special connection between the RPA and second-order pe...

AI resistance and epistemic agency: toward a relational framework for democratic and human-centered AI governance

Abstract Artificial intelligence (AI) increasingly mediates communication, interpretation, decision-making, and knowledge production, raising questions about how computational systems acquire epistemic authority. At the same time, resistance to AI is emerging across educational,...

Cryogenic Deformation Behavior of TiAl and Insights Into Embrittlement After High‐Temperature Exposure Combined With Secondary Ion Mass Spectroscopy of Near Surface Chemistry

This study investigates the embrittlement of TiAl after high‐temperature air exposure. The loss of room‐temperature tensile ductility persists even when tested under liquid nitrogen (−196 °C), with brittle fracture occurring at higher stress levels than typical room‐temperature f...

Intermolecular Carbon–Carbon Naphthalene Coupling Involves a Radical Mechanism Driven by Cytochrome P450 in Alternaria alternata

ABSTRACT Dihydroxynaphthalene (DHN) derivatives are precursors of biologically important molecules, including melanin and perylenequinones (PQs). Biosynthesis of DHN‐derived metabolites requires precise spatial control of radical reactions to form specific C─C or C─O─C bonds. Inv...

Importance of Energy and Molecular Transport on the Modeling of Explosion Limit and Explosion Behavior of Hydrogen-Oxygen Mixtures

Despite the classical developments and subsequent studies of individual transport mechanisms, many recent explosion-limit simulations still apply homogeneous formulations. Many recent study on explosion limits of reactive mixtures focuses on the usage of homogeneous models that n...

Development of the Chemical Reaction Mechanism for Oxide Film Formation and Decomposition in Rh-Based Three-Way Catalysts

A full-hybrid system incorporating a spark-ignition engine is regarded as essential for future passenger car powertrains. To achieve effective exhaust-gas purification in such vehicles, it is necessary to elucidate the characteristics of three-way catalysts and to develop both ph...
