Quality Thresholds for Angiogenesis Under Acoustic Manipulation in Engineered Vascular Tissues

Advanced Science, EarlyView.
Defined biological and physical quality thresholds achieved through acoustic manipulation regulate cellular alignment and spatial organization, promoting self‐assembling vasculature, extracellular matrix deposition, and angiogenic responses, thereby establishing critical acoustic patterning requirements for engineered vascular tissue development in ...

Developing Soft Interconnected Microchannel Network for 2D Skin‐Like Actuator

Advanced Science, EarlyView.
A soft interconnected network of microchannels is proposed to develop new pneumatic actuators for future bio‐inspired soft robots. Simultaneous stimulation of this network generates regional asymmetric strains in walls of microchannels whose interaction across the entire surface leads to bending curvatures in multidimensions.

Generalized Chemical Model for Warm Dense Hydrogen: Ionization Potential Depression and Molecular Dissociation Shifts

Contributions to Plasma Physics, EarlyView.
ABSTRACT Warm dense matter (WDM) is a complex state, where quantum effects, thermal excitations, and strong interparticle correlations coexist. Understanding its microscopic composition and medium‐induced modifications of atomic and molecular properties is essential for planetary modeling, fusion research, and high‐energy‐density experiments.

Origin of Physicochemical and Mechanical Stability of Low‐Temperature Prepared TiO2‐Based Photocatalytic Films: Surface Hydroxyl Density Matching

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Material science advances show how surface chemistry improves low‐temperature prepared TiO2‐SiO2 composite films. Using a colloidal‐based synthesis method instead of a powdered‐based one, researchers exploit hydroxyl groups' interfacial interactions to create nanoscale structures with superior physicochemical and mechanical stability.

Interplanetary frontiers: terraforming from an invasion science perspective

Oikos, EarlyView.
The pursuit of a multi‐planetary existence represents one of humanity's greatest frontiers. If applied justly, it offers an opportunity to extend its civilization's lifespan amid escalating sustainability crises on Earth. One approach increasingly gaining traction is terraforming, a hitherto theoretical ecological and evolutionary experiment revolving ...

Sliding Mode Control in Aerospace Applications: A Survey

International Journal of Robust and Nonlinear Control, EarlyView.
ABSTRACT Sliding mode control (SMC) enjoys robustness to matched and unmatched (in the case of minimum phase input‐output dynamics) bounded perturbations, and finite time convergence. Second‐order and higher‐order sliding mode control systems (2‐SMC/HOSMC) retain all the advantages of sliding mode control, but in addition can be applied to systems of ...

Core electron temperature and density in the innermost Saturn's magnetosphere from HF power spectra analysis on Cassini [PDF]

Journal of Geophysical Research: Space Physics, 2013
We analyze the large‐scale structures of electrons in Saturn's inner magnetosphere equatorial plane, from 2.8 to about 10 Saturnian radii (RS). The electron total density and core temperature are obtained using the quasi‐thermal noise spectroscopy method, based on the HF power spectra measurements acquired with the Cassini/Radio and Plasma Wave Science

From Flybys to Sample Return: A Review of Space Probes and Robotic Sampling Technologies for Small Bodies

Journal of Field Robotics, EarlyView.
ABSTRACT As a crucial puzzle piece of deep space exploration, exploring small bodies can provide significant scientific insights and valuable mineral resources. Unlike missions to the Moon and Mars, small‐body missions pose distinct technical challenges, including communication delays, weak gravity, and uncertain environments. This paper reviews a full

Vine Tendril‐Inspired Cold‐Programmable Shape‐Memory Polymer Composites Using Sugar Beet Pulp

Small, EarlyView.
Vine tendrils inspire a bio‐derived, cold‐programmable shape‐memory polymer composite (SMPC). Magnetically guided sugar beet pulp creates mesoscale heterogeneity within a glassy matrix, producing built‐in mechanical asymmetry for rapid, solvent‐free programming by simple stretching.

Embedded Interactions and Selective Disclosure: Network Effects on Conversations aboard Skylab

Symbolic Interaction, EarlyView.
How do absent others influence our interactions? We argue in this paper that interactions are embedded within networks formed by chains of specific relationships between known third parties. The anticipation of future interactions with external others conditions our interpretation of the current situation and affects our behavior in the interaction. We
