Programming Light‐Driven Surface Topographies in Liquid Crystal Elastomers for Potential Biomedical Applications Through Combined Experiments and Simulations

Advanced Materials Technologies, EarlyView.
A combined experimental and simulation study of light‐responsive liquid crystal elastomer surfaces operating under physiological conditions is reported, demonstrating programmable and highly spatially controlled topography formation through bottom‐side photomask exposure. Our study establishes a foundation for dynamic, light‐responsive biosurfaces with

Surrogate‐Optimized Flow‐Guided Miniature Condenser for Rapid Exhaled Glucose Detection

Advanced Materials Technologies, EarlyView.
A surrogate‐optimized miniature condenser guides humid exhaled flow toward cold surfaces to accelerate exhaled breath condensate collection. By improving vapor access within a compact footprint, the design increases sample yield. This enables post‐collection enrichment and rapid colorimetric glucose detection from dilute exhaled biomarkers within a 5 ...

Wavelength‐Multiplexed 2D Beam Steering via a Passive Diffractive Network

Advanced Optical Materials, EarlyView.
Illustration of a wavelength‐multiplexed diffractive beam steering system, which is composed of K cascaded diffractive layers, each containing phase‐modulating elements that are jointly optimized using deep learning–based optimization. When illuminated with a set of wavelengths {λ1,λ2,…,λNw}$\{ {{{\lambda }_1},{{\lambda }_2},\ldots ,{{\lambda }_{{{N}_w}

A Lie group variational integrator in a closed-loop vector space without a multiplier [PDF]

Mechanical Sciences
As a non-tree multi-body system, the dynamics model of four-bar mechanism is a differential algebraic equation. The constraints breach problem leads to many problems for computation accuracy and efficiency.

A Dynamic Analysis of the Plane Crank-and-Rocker Mechanisms with Clearances

Bulletin of JSME, 1980
The equations of motion of the plane four-bar mechanisms have been derived for all of possible numbers and positions of clearance-connections except the input-shaft position when the mechanisms rotate at constant speeds in a vertical plane. Applying the equations to a crank-and-rocker mechanism, the effects of the numbers and positions of clearance ...

Nonlocomotory Robotic Strategies for Dynamic Rotation Control in Terrestrial Robots: A Review

Advanced Robotics Research, EarlyView.
Terrestrial robots increasingly require rapid body rotation to maintain stability and agility in complex environments. This review shows nonlocomotory rotational control strategies that operate without ground contact, including reaction wheels, tails, bars, limbs, and thrusters.
