Additional lateral meniscus centralization reduces residual anterolateral rotatory instability after anterior cruciate ligament reconstruction and lateral meniscus repair

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose This study aimed to examine the effects of lateral meniscus (LM) centralization on anterolateral rotational stability in patients with anterior cruciate ligament (ACL) and LM injuries. The hypothesis was that performing LM repair and centralization on knees with LM lesions would control anterolateral rotatory instability (ALRI ...

Wearable Movement‐Tracking for Prodromal Parkinson's Disease Detection: A Cross‐Country Validation Study

Movement Disorders, EarlyView.
Abstract Background Models trained on accelerometer data have been proposed for detecting prodromal Parkinson's disease (PD). However, uncertainties in diagnosis timing in the UK Biobank (UKBB) may affect generalizability to other cohorts. Objectives The aim of the study was to evaluate the performance of previously published models for prodromal PD ...

Development of a Technique for Toughness Estimation in Dual-Phase Steels Using Representative Volume Elements

Metals
A novel approach to estimating the absorbed energy (toughness) in a uniaxial tensile test with only knowledge of the microstructure is presented. The flow behavior of each Dual-Phase (DP) steel grade is predicted using idealized Representative Volume ...

Fault Detection of Electric Motors via Symmetrized Dot Pattern‐Based Features

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT This study proposes a novel symmetrized dot pattern (SDP) approach using designed SDP‐based features, extracted from transformed vibration signals, for fault detection. These features describe the compactness, inclination, and shape of the “snowflake” diagram distributions.

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

ISMGEO Large Triaxial Apparatus

, 2018
The design of earth and rockfill dams is focused on ensuring the stability of the structure under a set of combined mechanical and hydraulic conditions that may occur both during construction and operative life of the dam. The prediction of the hydro-mechanical behavior of construction materials (which range from clayey soils to rockfill) is therefore ...

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.

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

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.
