Hand-arm resonance frequency and related neuromuscular activation

open access: yes, 2007
The ability of the hand-arm system (HAS) to transmit the vibrations depends on ages of the subjects, but also on gender. In order to parameterize the effects of vibrations on young sedentary subjects (i.e.

Photoreversible Polyurea Actuators With Spatiotemporal Control and Adaptive Mechanics

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A light–thermal responsive polyurea network incorporating reversibly dimerizable anthracene units enables spatiotemporal modulation of cross‐linking density and nearly 400‐fold stiffness tuning. Integrating programmable anisotropy, photopatterning, self‐healing, and photowelding within a single framework, this bioinspired “one network–multifunction ...

Rare Earth 3‐Hydroxyphenylacetate Complexes: Synthesis, Structural Characterization, and Surprising Improved Anticorrosion Performance on Mild Steel

open access: yesEuropean Journal of Inorganic Chemistry, EarlyView.
The rare earth (RE) aqua complexes using 3‐hydroxyphenylacetate ligand were prepared using the corresponding RE salt and the sodium salt of the ligand by a salt metathesis reaction. Two different structural motifs of the complexes, {[La(3hpa)3(H2O)] × 2H2O}n, and [RE(3hpa)3(H2O)]n (RE = Ce (2), Nd (3), Gd (4), Dy (5), Y (6), Er (7), Yb (8)) were ...

Reflex seizures and epilepsy surgery: A network approach case‐based exploration

open access: yesEpileptic Disorders, EarlyView.
Abstract Context Reflex seizures (RS) are defined by their consistent provocation by specific stimuli, encompassing a broad range from elementary sensory inputs to complex cognitive tasks. While RS are often encountered in clinical practice, their surgical management remains sparsely reported and poorly systematized.
