Clinical heterogeneity in a family with flail arm syndrome and review of hnRNPA1‐related spectrum
Abstract Objective Flail arm syndrome (FAS) is one of the atypical subtypes of amyotrophic lateral sclerosis (ALS). Mutations in hnRNPA1 encoding heterogeneous nuclear ribonucleoprotein (hnRNP) A1 are a rare genetic cause of ALS. Herein, marked clinical heterogeneity of FAS in a pedigree with a known hnRNPA1 variant was described to raise early ...

Anisotropy in nanocellular polymers promoted by the addition of needle‐like sepiolites [PDF]
This work presents a new strategy for obtaining nanocellular materials with high anisotropy ratios by means of the addition of needle‐like nanoparticles. Nanocellular polymers are of great interest due to their outstanding properties, whereas anisotropic

The interaction of polymer dispersed liquid crystal sensors with ultrasound [PDF]
Polymer dispersed liquid crystals (PDLCs) have been shown to be sensitive to ultrasound through the acousto-optic effect. The acousto-optic response of PDLCs was studied over a broad frequency range (0.3–10 MHz).

Conformational properties of active semiflexible polymers [PDF]
The conformational properties of flexible and semiflexible polymers exposed to active noise are studied theoretically. The noise may originate from the interaction of the polymer with surround- ing active (Brownian) particles or from the inherent motion of the polymer itself, which may be composed of active Brownian particles.

The symplectic group in Polymer Quantum Mechanics [PDF]
In this paper we provide the representation of the symplectic group $Sp(2n, \mathbb{R})$ in polymer quantum mechanics. We derive the propagator of the polymer free particle and the polymer harmonic oscillator without considering a polymer scale. The polymer scale is then introduced to reconcile our results with those expressions for the polymer free ...

Phase stability and dynamics of entangled polymer-nanoparticle composites. [PDF]
Nanoparticle-polymer composites, or polymer-nanoparticle composites (PNCs), exhibit unusual mechanical and dynamical features when the particle size approaches the random coil dimensions of the host polymer.

Conformational landscape of long semiflexible linear and ring polymers near attractive surfaces [PDF]
Conformations of a crowded neutral semiflexible polymer under confinement near an attractive wall are studied via coarse-grained simulations. We study the effects of the interplay of the length of the polymer, bending rigidity, and the repulsive crowder density on such equilibrium semiflexible polymer conformations.
