Organoid Coculture Models for Cancer Research and Immunotherapy

Med Research, EarlyView.
This review summarizes organoid coculture platforms, including submerged Matrigel culture, air–liquid interface, microfluidic/organoid‐on‐a‐chip, and 3D bioprinting, for reconstructing the tumor microenvironment to study tumor–stroma/immune crosstalk, evaluate immunotherapies, and enable drug screening.

Analysis of Mechanical‐Electrical‐Hydraulic Coupled Vibration Response Characteristics of Thermal Control Circulating Pumps Supported by Water‐Lubricated Bearings

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT The operational reliability of thermal control circulation pumps is significantly restricted by the multi‐physics coupled environment. To reveal the vibration transmission mechanisms and dynamic response characteristics under multi‐field coupled excitations, a multi‐DOF coupled dynamic representation of the overall system, incorporating the ...

Underwater Wireless Information Transmission Enabled by Asymmetric Electrical Double Layers

National Materials, EarlyView.
We proposed asymmetric electrical double layers as programmable iontronic interfaces for underwater wireless information transmission, with ion redistribution and transport serving as information‐bearing processes. Charge‐density asymmetry between coupled solid–liquid interfaces produces unequal interfacial ion distributions and, under nonequilibrium ...

Wide-band underwater acoustic absorption based on locally resonant unit and interpenetrating network structure

, 2010
The interpenetrating network structure provides an interesting avenue to novel materials. Locally resonant phononic crystal (LRPC) exhibits excellent sound attenuation performance based on the periodical arrangement of sound wave scatters.

Linear System Identification and Control of a Low‐Cost High‐Performance Omnidirectional Marine Surface Vehicle for Swarming Applications

Journal of Field Robotics, EarlyView.
ABSTRACT Marine operations traditionally rely on human intervention, a costly and disruptive method. Autonomous surface vehicles (ASVs) offer a powerful alternative, capable of operating autonomously, for extended periods, and with various sensors for various missions.

Design and Testing of a Minimal Configuration Underwater Micro‐Glider: Automating Lake and Reservoir Monitoring

Journal of Field Robotics, EarlyView.
ABSTRACT Uncrewed underwater vehicles (UUVs) have transformed oceanographic research through autonomous data gathering. Similarly, lake and other aquatic research can potentially be automated and transformed. However, UUVs would need to be smaller, lighter, less complex, and cheaper than currently available to make them more practical and user‐friendly
