Advanced Science, EarlyView.This study develops neural bioprinted piezoelectric scaffolds which construct local “sensor‐effector” circuit, inspired by the skeletal interoception system. Upon US stimulation sensing and mechanoelectrical coupling by PLLA nanofibers, the incorporated DRG neurons effect through Ca2+ influx‐induced enhanced secretion and expression of CGRP.

Dynamical Evolution of Elliptical Galaxies with Central Singularities
, 1997 We study the effect of a massive central singularity on the structure of a triaxial galaxy using N-body simulations. Starting from a single initial model, we grow black holes with various final masses Mh and at various rates, ranging from impulsive to ...

Rigid‐Flexible Coupling Units Enable Robust Large Birefringence
Advanced Science, EarlyView.A rigid–flexible coupling strategy, combining flexible (S3)2− linear units with rigid (VO4)3− tetrahedra, yields Sr4(VO4)2S3—a robust crystal exhibiting large birefringence (Δn = 0.52@550 nm) and remarkable thermal, air, and water stability. ABSTRACT Birefringent crystals are central to polarization control in laser technologies (e.g., wave plates and ...

Light‑Driven Propulsion of Graphene Aerogels in Microgravity
Advanced Science, EarlyView.Ultralight graphene aerogels convert laser light into thrust. Parabolic‐flight experiments directly compare their motion in microgravity and at 1 g, revealing order‐of‐magnitude enhancements in distance, velocity, and transient thrust when weight and friction are removed (∼50 times enhancement).

Triaxial tests on frozen ground: formulation and modelling [PDF]
, 2013 Artificial Ground Freezing (AGF) is a controllable process that can be used by engineers to stabilise temporarily the ground, provide structural support and/or exclude groundwater from an excavation until construction of the final lining provides ...

, 2003 While the use of galaxy clusters as {\it tools} to probe cosmology is established, their conventional description still relies on the spherical and/or isothermal models that were proposed more than 20 years ago. We present, instead, a deprojection method

A constant limiting mass scale for flat early-type galaxies from z=1 to z=0: density evolves but shapes do not [PDF]
, 2011 We measure the evolution in the intrinsic shape distribution of early-type galaxies from z~1 to z~0 by analyzing their projected axis-ratio distributions.

Advanced Intelligent Systems, EarlyView.This study presents a compact, three IMU wearable system that enables accurate motion capture and robust gait‐feature extraction, thereby supporting reliable machine learning‐based balance evaluation. Accurate assessment of balance is critical for fall prevention and targeted rehabilitation, particularly in older adults and individuals with ...
