Curvature‐Directed Elongation and Chiral Tilting Drive Asymmetric Tissue Patterning

open access: yesAdvanced Science, EarlyView.
Curvature and cell handedness together break tissue symmetry. On convex and concave surfaces, cells elongate along opposite geometric axes and tilt in a consistent chirality‐driven direction, yielding opposite alignment patterns from the same cells. Reversing intrinsic cell chirality reverses both.

Process‐informed co‐optimization of liquid air energy storage and data centers under off‐design thermodynamic operation

open access: yesAIChE Journal, EarlyView.
Abstract The rapid growth of AI data centers (AIDCs) is intensifying stress on power systems and exposing operators to volatile electricity markets. This work develops a process‐informed co‐optimization framework that integrates liquid air energy storage (LAES) with AIDC operation. Unlike black‐box storage models, the proposed formulation captures LAES

Task complexity, focus on form, and second language development. [PDF]

open access: yes, 2009
Tasks have received increased attention in SLA research for the past decade, as has the role of focus on form. However, few empirical studies have investigated the relationship among tasks, focus-on-form techniques, and second language (L2) learning ...

Versatile Standing Wave Generation Between Arbitrarily Oriented Surfaces Using Acoustic Metasurface Deflectors and Retroreflectors

open access: yesAdvanced Intelligent Systems, Volume 7, Issue 3, March 2025.
A novel method for generating versatile standing wave fields using an acoustic metasurface deflector and retroreflector is introduced. By overcoming traditional constraints of parallel surfaces, the approach enables customizable wave patterns and enhances applications in particle manipulation.

Double Helix Structure for Stable Flexural Actuation in Soft Robotics

open access: yesAdvanced Intelligent Systems, EarlyView.
This work introduces a double‐helical architecture for soft robotic actuators that enhances twisting resistance, increases output force, and minimizes undesired deformation. Actuators driven by shape‐memory alloy wires exhibit a roughly fivefold higher torsional/flexural stiffness ratio and 50% greater force output.

A Compact Multijoint Finger Motion Sensing Module for Flexible Exoskeleton Applications

open access: yesAdvanced Intelligent Systems, EarlyView.
Addressing the motion estimation gap in underactuated wearable electronics, a highly integrated sensor alongside a customized readout circuit is proposed. Featuring a screen‐printed layout and optimized horseshoe geometry, this design establishes an optimal feedback mechanism for flexible hand exoskeletons while eliminating wiring clutter.
