Spatiospectral Photoacoustic Microscopy With Gain‐Switched Ti:Sapphire Laser for High‐Accuracy Molecular Dynamics Imaging

Laser &Photonics Reviews, EarlyView.
Spatiospectral photoacoustic microscopy is enabled by stable, wavelength‐tunable dual‐pulse excitation from a gain‐switched Ti:sapphire laser. Intrinsically synchronized 532‐nm and NIR‐I pulses provide single‐scan, co‐registered mapping of oxygen saturation and indocyanine green dynamics in vivo.

Linear Mechatronic Modeling of Rectangular Tank Sloshing Dynamics

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT Sloshing dynamics in partially filled tanks can strongly influence system‐level behavior when fluid motion couples with rigid‐body dynamics. This paper presents a linear and acausal two‐dimensional sloshing model for rectangular tanks, based on the reformulation of established sloshing theory within a modular, multi‐domain modeling framework ...

Real‐Time Fractional Control of an Electrohydraulic System Using Low‐Cost Technology

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT Advances in control methods for electrohydraulic systems (EHS) improve performance by addressing nonlinearities and unknown parameters, although most studies are limited to numerical simulations. Furthermore, research with experimental validation often relies on high‐performance computing equipment, specialized data acquisition cards, and ...

Initial State Privacy of Nonlinear Systems on Riemannian Manifolds

International Journal of Robust and Nonlinear Control, EarlyView.
ABSTRACT In this paper, we investigate initial state privacy protection for discrete‐time nonlinear closed systems. By capturing Riemannian geometric structures inherent in such privacy challenges, we refine the concept of differential privacy through the introduction of an initial state adjacency set based on Riemannian distances.

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

A Design Specifications Template for Wearable Haptic Interfaces: A Case Study for Robotic Gripper Applications

Journal of Field Robotics, EarlyView.
ABSTRACT Wearable haptic interfaces are increasingly important for enhancing human robot collaboration, particularly in decision critical tasks that require intuitive and reliable interaction. Despite advances in wearable systems, existing designs often lack a structured framework that systematically integrates sensing, actuation, control, and user ...
