Comparison of Consumer Smartwatch and Research‐Grade Accelerometer‐Derived Step Counts in Amyotrophic Lateral Sclerosis

Muscle &Nerve, EarlyView.
ABSTRACT Introduction/Aims Objective, scalable measures of function are needed in amyotrophic lateral sclerosis (ALS). Research‐grade accelerometers are promising but may be difficult to deploy for prolonged remote monitoring, whereas consumer smartwatches offer a practical alternative. We evaluated the feasibility of long‐term smartwatch monitoring in

Polymaterial Lattice Discrete Particle Model for the Optimization of Lightweight Aggregate Concrete: Intragranular Fracture and Compression Behavior

International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT Lightweight aggregate concrete (LWAC) offers clear advantages for sustainable construction, including reduced density and improved thermal insulation. However, its mechanical and fracture behavior is difficult to characterize due to the heterogeneity and brittle crushing of porous lightweight aggregates.

Rock test cell with true triaxial capability

, 1999
Conventional so-called triaxial test cells apply the axial stress to a cylindrical sample using steel platens, with the confining stress developed via an annulus of hydraulic fluid retained by a liner in a pressure cell.

Modeling Biocemented Sands: Hypoplastic Model for MICP‐Based Ground Improvement

International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT Bio‐cementation offers a sustainable and low‐carbon alternative to conventional ground improvement methods, aligning with the growing demand for green geotechnical solutions. To enable reliable numerical simulation of bio‐cemented soil behavior in engineering applications, advanced constitutive models are required to account for the effects of

Triaxial Tests for Soils

, 2013
This document presents a brief explanation of the shear strength theory, an overview of the main types of triaxial tests that are performed more frequently in a geotechnical laboratory and a detailed listing of the different components that make up the triaxial test equipment acquired by the LanammeUCR Geotechnical Laboratory.

Overshooting of Hypoplastic Models With Intergranular Strain: Manifestation, Implications and Remedy

International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT Intergranular strain extensions of hypoplasticity (IGS, ISA, GIS) are widely used to model small‐strain and cyclic soil behaviour. However, recent studies and our own simulations reveal that these models can exhibit stress overshooting not only under repeated small loading cycles but also during monotonic loading.

Dietary Protein Reduction During Isocaloric Conditions Reduces Body Weight in Men With Overweight or Obesity

Obesity, EarlyView.
Protein restriction, while meeting minimum requirements, induced weight loss and increased FGF21 in men with obesity under isocaloric conditions, without caloric restriction. ABSTRACT Objective Dietary protein reduction increases plasma fibroblast growth factor 21 (FGF21) and energy requirements in lean men under eucaloric conditions.

Evaluation of Fiber‐Matrix Debonding in Glass, Carbon, and Hybrid Fiber Composites Under Transverse Loading by Full‐Field Measurements

Polymer Composites, EarlyView.
An experimental multiscale approach to investigate how fiber spacing, orientation, and material hybridization influence fiber‐matrix debonding and transverse cracking. ABSTRACT This study aims to experimentally quantify fiber‐matrix debonding and transverse crack evolution in single‐fiber and double‐fiber composite specimens, with particular emphasis ...

Exploring the Use and Impact of Composite Materials in Robotics: A Systematic Review

Journal of Field Robotics, EarlyView.
ABSTRACT Lightweight and high‐strength materials are important in robotics, as structural design impacts efficiency, payload capacity, and energy consumption. Composite materials, with their superior stiffness‐to‐weight ratios and multifunctional properties, offer clear advantages over conventional metals and polymers.
