On Representation of Macroscopic Crack in Periodic Fine‐Scale Discrete Mechanical Models

ABSTRACT The evolution of strain localization and the corresponding macroscopic response obtained in multiscale modeling of softening heterogeneous materials strongly depend on the boundary conditions imposed on the fine‐scale model. For rectilinear models (e.g., squares or cubes...

Influence of the used solvent on the efficiency of the extraction of cathode materials for direct recycling

Lithium-ion batteries are playing an increasingly significant role in modern mobility and energy storage. Their increasing quantity and the limited amount of material resources available on earth will place great demands on the most efficient recycling in the future. In this pape...

Strain rate effect on frictional behaviour of Hardox 450 steel

Abstract The influence of strain rate on the frictional behaviour of high-strength Hardox 450 steel have been investigated using both experimental and numerical approaches. The ring compression test method was employed to identify the friction coefficient across a wide range of s...

Self-Assembled Monolayers and Solvent Composition Control the Orientation and Work Function of Pyrene-Based [7]Helicenes

Abstract Self-assembled monolayers (SAMs) and solvent composition critically influence the orientation and electronic properties of functional organic molecules, paving the way for energy conversion and optoelectronic devices. PeakForce quantitative nanomechanics atomic force mic...

GRAN-EEG: A ghost-residual attention network for subject-independent EEG-based objective pain recognition

Objective pain assessment is important for supporting clinical decision-making, particularly when patients are unable to provide reliable self-reports. This study proposes GRAN-EEG, a Ghost-Residual Attention Network for subject-independent pain recognition using electroencephalo...

In vitro contact force evaluation of robotic magnetic navigation catheters; Head to head comparison of different catheters and different settings

Background The Stereotaxis Robotic Magnetic Navigation (RMN) system uses an external magnetic field to navigate catheters inside the heart during arrhythmia ablation. This study compared in vitro maximal contact force (CF) achieved with different irrigated RMN ablation catheters...

Waste-Derived Biochar for Sustainable Wastewater Treatment and Resource Recovery: A Review from the Circular Economy Perspective

The growing generation of organic waste and the increasing demand for sustainable wastewater treatment have stimulated interest in waste-derived biochar as a multifunctional material for pollutant removal and resource recovery. This review critically evaluates the relationships b...

Which AI? A Comparative Evaluation of Generative AI and Neuro‐Symbolic AI for Silicon Sampling

ABSTRACT This study examines how the choice of AI model and its architecture influences distributional fidelity in silicon sampling. Silicon samples, AI‐generated synthetic respondents used to simulate human survey responses, are increasingly proposed as substitutes for tradition...

Atlas of cell types and regulatory elements underlying human facial diversity

Abstract Human genetic diversity generates an astonishing variety of facial shapes, and craniofacial anomalies rank among the most common birth defects. Identifying the cellular mechanisms that mediate the genome’s influence on facial variation remains a challenge. Here we create...

Spinal-Multiple-Myeloma-SEG: A Dual-Energy CT Dataset Extended with Trabecular Bone Segmentation of Lumbar Vertebrae

We present an extension of the publicly available Spinal-Multiple-Myeloma-SEG dataset, a dual-energy CT imaging resource for multiple myeloma research. The purpose of this dataset is to enable voxel-wise analysis of vertebral bone microstructure by adding expert-validated segment...

Work ability configurations and conditional HR decision premises: a programme-oriented framework for age management

Purpose Ageing workforces require organisations to decide what to prioritise when older workers' work abilities differ. This article develops the Cyclical Meaning Pattern of Abilities (CMPA) as a programme-oriented human resource (HR) decision heuristic. CMPA conceptualises how c...

Consensus-Based Definitions for Vocal Biomarkers: The International VOCAL Initiative.

Introduction: Voice-based health technologies are growing rapidly, but they lack standardized terminology, which hinders interdisciplinary collaboration, research quality, and clinical translation. The objective of this work was to develop universally accepted definitions in the...

Utilization of Recycled Brick Aggregate in Cementitious Composites: Mechanical Performance, Cement Matrix Solidification Effect and Life Cycle Assessment

The growing production of construction and demolition waste has been stimulating the need to look for sustainable alternatives to natural aggregate used in the production of cement composites. This study evaluates the potential use of recycled brick material as a substitute for n...

Ion-Pair Amphiphile Vesicles Modified by Native and Oleyl-Substituted Hyaluronan: Colloidal Properties and Interfacial Relaxation Dynamics

Abstract How hydrophobic modification of hyaluronan changes its coupling to cationic ion-pair amphiphile (IPA) membranes beyond electrostatic surface association remains insufficiently resolved. Here, a counterion-depleted carbethopendecinium/dodecylbenzenesulfonate IPA was suppl...

Multimodal surface defect detection from wooden logs for sawing optimization

We propose a novel, cost-effective method for knot detection on the surface of wooden logs using multimodal data fusion. Knots are a primary factor affecting the quality of sawn timber, making their detection fundamental to any timber grading or cutting optimization system. Howev...

Simulation-based framework for early-stage assessment of building-integrated photovoltaics and battery storage in urban district master planning: Vienna case study

Dense urban districts require decision-support methods that allow architects and planners to evaluate renewable generation, storage and demand interactions while the master plan is still flexible. This paper presents a simulation-based workflow for early-stage assessment of build...

Time-Varying Electromagnetic Systems - Challenges and Methodologies

Time-varying (TV) electromagnetic (EM) systems and devices introduce a fundamentally new framework in EM theory by extending classical concepts beyond traditional time-invariant formulations. In conventional EM systems, temporal invariance combined with the steady-state assumptio...
