Optimal Design of Tuned Mass-Damper-Inerter for Structure with Uncertain-but-Bounded Parameter
Buildings, 2022 In this study we focus on the H∞ optimization of a tuned mass damper inerter (TMDI), which is implemented on an harmonically forced structure of a single degree of freedom in the presence of stiffness uncertainty. Posed as a min-max optimization problem,

Thermodynamics of Animal Locomotion [PDF]
Physical Review Letters, 2020 Muscles are biological actuators extensively studied in the frame of Hill's classic empirical model as isolated biomechanical entities, which hardly applies to a living organism subjected to physiological and environmental constraints. Here we elucidate the overarching principle of a \emph{living} muscle action for locomotion, considering it from the ...

An epithelial GPR35 isoform supports tumor‐associated transcriptional and metabolic phenotypes
FEBS Letters, EarlyView.GPR35 generates two functionally distinct isoforms with previously unresolved roles. GPR35‐short mediates immune‐cell chemotaxis, while GPR35‐long is enriched in colorectal cancer epithelium, where it supports increased metabolism, proliferation, and tumor‐associated transcriptional programs.

Fatigue research of metro car body based on operational loads [PDF]
Railway SciencesPurpose – The principle of infinite life design currently directs fatigue resistance strategies for metro car bodies. However, this principle might not fully account for the dynamic influence of operational loads and the inevitable presence of defects ...

Feedforward-loop phase-locked loop based estimation scheme for sensorless IPMSM drive system
e-Prime: Advances in Electrical Engineering, Electronics and Energy, 2023 The existence of mechanical speed sensors brings challenges of system reliability. Therefore, drives without speed and position sensors attract much popularity in interior permanent-magnet synchronous motor (IPMSM) drive system. This paper provides a new

FEBS Open Bio, EarlyView.TisIBP8, a fungal‐derived hyperactive ice‐binding protein, helps Caenorhabditis elegans survive dehydration. It localizes near cell membranes, reduces cell damage, and helps maintain membrane structure during drying. These results suggest that ice‐binding proteins can protect cells from dehydration stress as well as freezing stress.
