Detection of Thermally Induced Damage in Large-Format Lithium-Ion Batteries Using Electrochemical Impedance Spectroscopy

Thermally induced damage in lithium-ion batteries (LIBs) is a critical safety concern, especially when approaching thermal runaway (TR) conditions. In this study, electrochemical impedance spectroscopy (EIS) was used to detect thermally induced damage in large-format prismatic LI...

Analysis of a Large-Scale Citizen Science Study on the Public Collaborative Reassembly of an Archaeological Stone Artifact

Archaeologists often face the complex and time-consuming task of reassembling fragments from broken artifacts. Fragment reassembly is traditionally done manually by domain experts. Automatic algorithms have advanced but are typically tailored to specific fragment types, often ass...

Collostructional analysis: a Bayesian approach

Abstract This article explores a Bayesian approach to collostructional analysis, a method that investigates the associations between lexical items and grammatical constructions. Traditional collostructional analysis has proved to be an effective tool for studying constructional s...

Unraveling the Mechanism for Phonon Based Heat Transport in Metal‐Organic Frameworks

ABSTRACT Heat transport is a crucial process for many applications of metal‐organic frameworks (MOFs), including gas adsorption, catalysis, and bio‐encapsulation. A prerequisite for designing MOFs with optimal thermal conductivities is developing a profound understanding of the u...

Characterization of Rain Attenuation for Millimeter Wavelengths for Realistic Nonrotational Symmetric Drop Shapes

ABSTRACT The use of frequencies above 30 GHz (millimeter waves) for communication purposes is nowadays a necessity, both for terrestrial (e.g., 5G/6G) and satellite links. One reason is the need for more bandwidth and the fact that “traditional” frequency bands are already fully...

Hydrodynamic and Magnetostatic Characterization of a Rotating Vortex-Based Nanobubble Generator

This study combines experimental characterization, computational fluid dynamics (CFD) and magnetostatic modelling to investigate a rotating vortex-based nanobubble generator incorporating six permanent magnets. The combined approach distinguishes the hydrodynamic generation pathw...

Deeply nonlinear magnon-photon hybrid excitation

We investigate the microwave-power dependence of magnon-photon coupling in a yttrium iron garnet-sphere/split-ring resonator hybrid system at room temperature and demonstrate that nonlinear spin-wave interactions suppress the coupling through power-induced dissipation of magnetos...

Enhancing the performance of cylindrical Li-ion batteries via mechanical preload and optimization of impedance

Pouch and prismatic battery cells are usually mechanically preloaded for their use in electric vehicles to improve the performance and service life of battery cells. Although these positive effects are well known and studied in literature, only these cell formats continue to be m...

Development and Validation of Quasi-Dimensional Multi-Zone Combustion Model for Homogeneous Reactivity-Controlled Compression Ignition with Renewable Fuels—Part 1: Fuel and Temperature Stratification Prediction

As part of the dtec.bw MORE project, serial hybrid powertrains featuring alternative combustion regimes, specifically homogeneous reactivity-controlled compression ignition (hRCCI), are under investigation to maximize thermal efficiency while minimizing NOx and soot emissions. Th...

Developmental divergence in gene regulation underlies trophic innovation in Lake Victoria cichlids

Abstract The role of developmental shifts in the emergence of ecological diversity during adaptive radiation remains largely uncharacterized. Here, we investigate the developmental gene regulatory landscape of trophic innovation in the rapid adaptive radiation of cichlid fishes f...

Evaluating Pose Estimation Uncertainty From Automatic Point Cloud Registration in Multi‐Sensor Robotic Systems

ABSTRACT The poses derived from automatic point cloud registration between stationary laser scans that occur naturally in robotic multi‐sensor systems operating in stop‐and‐go mode have the potential to greatly improve and aid localization and trajectory estimation. The uncertain...

EXTREME VALUES OF DERIVATIVES OF DIRICHLET L -FUNCTIONS

Abstract In this paper, we establish lower bounds for extreme values of derivatives of Dirichlet L -functions in the range 1 / 2 < σ < 1 $1/2<\sigma <1$ 1 divided by 2 less than sigma less than 1 . Compared with the work of Aistleitner et al. [‘On large values of L ( σ , χ ) $L(\...

Dual‐Function Cosubstrates Enable Threonine Dehydrogenase‐Driven Chemoenzymatic Pyrrole Synthesis

ABSTRACT Preparative biocatalytic synthesis of substituted pyrroles remains challenging despite recent advances in enzymatic α‐aminoketone generation. In this study, we report a concurrent chemoenzymatic cascade to disubstituted pyrroles based on threonine dehydrogenase (ThrDH)‐c...

Non-local Fourier Laws for Heat Propagation via Fractional Powers of Vector Operators

Abstract The present work is devoted to the study of fractional powers of vector operators, with particular emphasis on the gradient operator with non-constant coefficients. Within the setting of the Clifford algebra $$\mathbb {R}_n$$ R n , this operator turns out to have bisecto...

Starting from the Navier–Stokes equations in rotating spherical coordinates with depth-varying density and eddy viscosity, we derive an asymptotic model describing non-equatorial wind-generated ocean drift currents. Our approach allows for large-scale flows that cannot be capture...
