The Origin of Coherent Cosmic Magnetic Fields: Dynamic Magnetic Divergence and Continuum Vorticity in the LIFE Framework

The ubiquity of coherent, microgauss-scale () magnetic fields across galaxy clusters, cosmic filaments, and pristine high-redshift systems presents an enduring conundrum in modern astrophysics. Standard cosmological magnetogenesis relies on the Biermann battery mechanism to gener...

Den2Obj: A command-line tool for producing isosurfaces from electron density data files

A command-line tool for generating isosurfaces from electron-density scalar fields. Den2Obj reads VASP CHGCAR, PARCHG, and LOCPOT files as well as Gaussian Cube files, and exports meshes in OBJ, PLY, and STL formats. It also supports conversion to the lossless compressed D2O form...

A multi-mode active frequency support strategy for a grid-friendly integrated PV-ES system

The integration of photovoltaic (PV) and energy storage (ES) is an effective solution to mitigate PV output fluctuations and enhance solar energy utilization. However, existing PV-ES coordination schemes are often limited by insufficient consideration of source-side support capab...

A Unified Microscopic Picture of Cation and Anion Migration in MAPbI3

Abstract Passivating defects and restricting defect mobilities in halide perovskites to increase device lifetimes has become a main field of research. Modeling structure and mobility of point defects is an essential contribution to this endeavor. We employ molecular dynamics, bas...

Neural network methods for two-dimensional finite-source reflector design

Abstract We address the inverse problem of designing two-dimensional reflectors that transform light from a finite, extended source into a prescribed far-field distribution. We propose a neural-network parameterization of the reflector height and develop two differentiable object...

Inhomogeneous Continuum Cosmology and the Hubble Tension: Dynamical Metric-Inertial Expansion in Field-Depleted Environments

The statistically irreconcilable discrepancy exceeding between local late-time determinations of the Hubble constant (; SH0ES/HST) and early-universe measurements inferred from the Cosmic Microwave Background under CDM (; Planck) constitutes the most formidable observational cris...

Non-Linear Gravito-Inertial Cavity Compaction and the Rapid Genesis of Supermassive Black Holes and Luminous Galaxies at z > 10

Recent photometric and spectroscopic observations by the James Webb Space Telescope (JWST) have revealed a startling population of massive, luminous galaxies () and supermassive black holes () at redshifts , when the universe was only 300 to 450 million years old. These observati...

Real-World Driving CO2 Emissions and Engine Thermal Efficiency Evaluation of Hybrid Vehicles: A Regression-Based Parameter Identification Approach

Real-world driving tests reflect vehicle performance in everyday use, but extracting energy conversion data from extensive measurements remains challenging. The study compared a hybrid electric vehicle and a plug-in hybrid electric vehicle, with the latter operated in charge-sust...

Aromatic Polyimine‐Derived Carbon Membranes for Efficient Hydrogen Separation

ABSTRACT Hydrogen is a key energy carrier for the transition toward sustainable energy systems, yet its widespread implementation relies on efficient and selective purification from mixed gas streams. Carbon membranes have emerged as promising candidates for hydrogen separation d...

Resolution of the Galactic Rotation Curve Anomaly via Local Interaction Field Equilibrium: Gravito-Inertial Acceleration Scaling and Wheeler GEON Halos

The persistent flat rotation curves observed in spiral galaxies have remained one of the principal empirical crises of modern astrophysics, compelling the standard cosmological paradigm to invoke non-baryonic Cold Dark Matter (CDM) halos that have eluded direct laboratory detecti...

One-dimensional elastoplastic models with isotropic hardening as differential inclusions in primal form

To improve the numerical simulation of rockfall protection barriers, this work addresses an extension of a one-dimensional model for elastoplasticity using a friction element and a spring in series, to include isotropic hardening and unilateral behavior. We reformulate the result...

A Framework for Using Metadata to Combine Data Sets in Official Statistics

There are increasing numbers of sources available for the production of official statistics. When one is interested in making new output or redesigning the input that is used for existing output, it might not always be clear if and how the intended output can be produced from the...

Light‐Driven Control of Polar Order in Ferroelectric Nematic Liquid Crystals

ABSTRACT Ferroelectric nematic (N F ) liquid crystals are polar fluids that combine long‐range orientational order with spontaneous macroscopic polarization and exceptionally large dielectric permittivity. While these properties make N F materials attractive for responsive soft d...

Cross-Machine Empirical Validation of Macroscopic Multi-Sensor Flux-Asymmetry Precursors for Tokamak and Stellarator Disruption Mitigation

Predicting and mitigating catastrophic plasma disruptions remains the primary operational imperative for magnetic confinement fusion devices, including ITER and future power reactors. While classical single-fluid magnetohydrodynamics (MHD) enforces strict local magnetic solenoida...

What is energy literacy? From prerequisite for participation to social practice

Energy literacy is often assumed to be a prerequisite for public participation in energy. But, it remains unclear how people's energy literacy leads to participation. This raises questions about dominant conceptualisations of energy literacy in relation to participation. We inves...

Hybrid control with half-cycle adaptive switching rule and integral action for a Totem-Pole bridgeless rectifier

This paper proposes a hybrid control strategy for a single-phase Totem-Pole Bridgeless Rectifier (TPBR), modeled as an affine switched system combining controlled and autonomous dynamics under parametric uncertainties. The TPBR is analytically characterized as a current-dependent...

Controlling Linear and Non‐Linear Mechanics in Multicomponent Hydrogels Through Programmable Supramolecular and Covalent Interactions

ABSTRACT In our native extracellular matrix (ECM), hierarchical interactions—supramolecular and covalent—between multiple components give rise to complex mechanical properties. Reproducing such emergent properties in synthetic hydrogels remains challenging, particularly the non‐l...

CRB3 and ARP2/3 regulate cell biomechanical properties to set epithelial monolayers for collective movement

Several cellular processes during morphogenesis, tissue healing or cancer progression involve collective cell migration. To set the cells for motion, there is an initial breaking of organization of the epithelial tissue that modifies the epithelial phenotype and axis of polarity....

The Foundations of Local Interaction Field Equilibrium (LIFE Theory): From Minkowski Spacetime and Wheeler GEONs to Unified Volumetric Force Densities

The quest to unify mechanics, electrodynamics, and gravitation into a single, cohesive framework has driven theoretical physics for over a century. Classical physics and modern field theory rest upon pillars forged by visionary pioneers. Without Sir Isaac Newton’s formulation of...
