Elastic Instability Triggered Pattern Formation [PDF]
, 2009 Recent experiments have exploited elastic instabilities in membranes to create complex patterns. However, the rational design of such structures poses many challenges, as they are products of nonlinear elastic behavior.

Advanced Science, EarlyView.This study investigates how CTCs survive varying shear stress during hematogenous metastasis. We uncover a self‐protection mechanism, by which non‐adherent CTCs adapt to high shearing milieu through accumulated cytoplasmic myosin‐mediated disruption of myosin‐actin binding, attenuating force transmission into chromatin to protect CTCs from shear ...

First Evidence of a Precessing Jet Excavating a Protostellar Envelope [PDF]
, 2006 We present new, sensitive, near-infrared images of the Class I protostar, Elias 29, in the Ophiuchus cloud core. To explore the relationship between the infall envelope and the outflow, narrowband H2 1-0 S(1), Br-gamma, and narrowband K-continuum filters

Advanced Science, EarlyView.A CCM‐based architectural strategy is introduced for high‐temperature PEM fuel cells, enabling MPL‐free carbon paper gas diffusion layers via decal‐transfer processing. By co‐engineering the CCM, GDL, and a G‐foam flow field, oxygen transport is enhanced while phosphoric‐acid leakage is suppressed, resulting in high power density and stable operation ...

Electrohydraulic Folding Ring Actuators for Radial Contraction
Advanced Science, EarlyView.This work presents an Electrohydraulic Folding Ring Actuator that combines high‐performance electrohydraulic actuation with origami‐inspired folding geometry to achieve constricting radial actuation. This integration yields significant inner lumen constriction, alongside a gripping force capable of holding objects exceeding four times the actuator's ...

Advanced Science, EarlyView.Defect‐configurational origins of the asymmetric apparent electrostrain are revealed in different piezoelectric ceramics via atomic‐scale visualization of defect configurations. Migration of oxygen vacancies leads to the electrobending effect in N2‐sintered BaTiO3, while defect dipoles in Ba0.99TiO2.99 generate true asymmetric electrostrain without ...
