Dual‐Metasurface‐Integrated Fiber Array for Bidirectional Cylindrical‐Vector‐Beam Multiplexed Communication Using Off‐Axis Spatial Manipulation

Laser &Photonics Reviews, EarlyView.
A dual‐layer metasurface is integrated on a fiber‐array facet to realize compact, plug‐and‐play free‐space optical links with cylindrical vector beam (CVB) space‐division multiplexing. An optimized off‐axis collimation layer steers multiple channels, while a Dammann vortex layer performs polarization–topology conversion for bidirectional CVB (de ...

Nutritional Treatment After Discharge of Older Patients at Nutritional Risk: A Study Protocol for a Feasibility Study

Medicine Advances, EarlyView.
Older patients at nutritional risk experience a nutritional gap at hospital discharge, and effective cross‐sector nutritional care models remain lacking despite existing evidence. This study's results may help inform the development of a model for large‐scale implementation.

Optimizing Ex Vivo MRI and Controlling the Roll of the Specimen Using Container‐ and Brain‐Specific 3D‐Printed Holders

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose Positioning and stabilizing a specimen in a container in preparation for ex vivo MRI are challenging. In addition, ex vivo MRI is often performed using preclinical scanners with gradient nonlinearity and nonhomogeneous sensitivity, requiring optimal placement.

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 ...
