Three Benefits of Using Nonlinear Compliance in Robotic Systems Performing Cyclic Tasks: Energy Efficiency, Control Robustness, and Gait Optimality

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT Nonlinearity in parallel compliance can be exploited to improve the performance of locomotion systems in terms of (1) energy efficiency, (2) control robustness, and (3) gait optimality; that is, attaining energy efficiency across a set of motions. Thus far, the literature has investigated and validated only the first two benefits.

Machine Learning‐Assisted Sensitivity Analysis for Stochastic Fatigue Life Modeling of Metals

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT Predicting fatigue life with precision requires more than isolated evaluations of mechanical properties; it requires an integrated approach that captures the interdependencies between various parameters, including elastic modulus, tensile strength, yield strength, and strain‐hardening exponent.

Neurofilament Light Chain Levels, Skeletal Muscle Loss, and Nutritional Decline: Key Prognostic Factors in Amyotrophic Lateral Sclerosis

Muscle &Nerve, EarlyView.
ABSTRACT Introduction/Aims Hypermetabolism and weight loss are established negative prognostic factors in amyotrophic lateral sclerosis (ALS). However, the role of individualized body composition parameters in predicting ALS progression has been underexplored. This study aimed to investigate the correlation between nutritional parameters, neurofilament

Fabrication and Characterization of Hybrid Bio‐Composites of Poly(vinyl alcohol)/Poly(L‐lactic acid) Blends With Cotton and Bleached Jute

Nano Select, EarlyView.
Hybrid composites with tunable balance properties were prepared using PVA and PLLA blend matrix reinforcements with cotton or bleached jute. Better bonding capacity between filler and matrix and also fiber absorb more heat as compared to PVA and PLLA, which help to enhance thermal stability.
