Microstructure Reconstruction in Battery Electrodes Using Machine Learning Based on Low‐Voltage Focused Ion Beam–Scanning Electron Microscopy Tomography Images

Advanced Engineering Materials, EarlyView.
Low‐voltage FIB‐SEM tomography combined with a image preprocessing pipeline improves phase contrast and enables reliable machine‐learning segmentation of conductive networks in lithium‐ion battery electrodes. Structural descriptors are extracted from segmented images, done semimanually and automated, and compared.

Impact of Teleparallelism on Addressing Current Tensions and Exploring the GW Cosmology

The Astrophysical Journal
The H _0 and S _8 tensions highlight critical discrepancies in modern cosmology, challenging the standard Lambda cold dark matter model. The H _0 tension arises from conflicting measurements between local probes and early-Universe predictions. Similarly,

Influence of Scan Strategies in Electron Beam Powder Bed Fusion on Solidification, Microstructure, and High‐Temperature Compressive Properties of γ′‐Strengthened Inconel 738LC

Advanced Engineering Materials, EarlyView.
Experiments and thermophysical simulations were conducted to investigate the electron beam powder bed fusion electron beam (PBF‐EB/M) process for the γ′‐strengthened nickel‐based superalloy Inconel 738LC. The results demonstrate the impact of process‐induced microstructural variations on high‐temperature mechanical behavior, providing a basis for ...

Influence of displacement damage dose on dark current distributions of irradiated CMOS image sensors [PDF]

Dark current increase distributions due to displacement damages are modeled using displacement damage dose concept. Several CMOS image sensors have been exposed to neutrons or protons and we have characterized their degradation in terms of dark current ...

Constraining Extended Teleparallel Gravity via Cosmography: A Model-independent Approach

The Astrophysical Journal
As a classical approach, the dynamics of the Universe, influenced by its dark components, are unveiled through prior modifications of Einstein’s equations.

On oscillating dark energy

Astroparticle Physics, 2006
Distance-redshift data can impose strong constraints on dark energy models even when the equation of state is oscillatory. Despite the double integral dependence of the distance on the equation of state, precision measurement of the distance-redshift relation for z=0-2 is more incisive than the linear growth factor, CMB last scattering surface distance,

Fock-selected topological dark matter and metastable dark energy

Nuclear Physics B
We construct and test a candidate-level covariant effective field theory in which the defining algebraic condition motivated by the hidden Fock symmetry of the bound Coulomb problem selects a topological dark-matter sector, while a resolved matter ...
