Holographic Mapping of Orbital Angular Momentum using a Terahertz Diffractive Optical Neural Network

open access: yesAdvanced Intelligent Discovery, EarlyView.
A compact six‐layer diffractive optical neural network enables direct recognition and spatial mapping of terahertz (THz) orbital angular momentum (OAM) beams. Fabricated by 3D printing, the system distinguishes nine OAM modes and their superpositions with high fidelity, good efficiency, and low crosstalk, offering a scalable solution for THz ...

Circulating Exosomes Drive Persistent Neuronal Dysfunction in Post‐Herpetic Neuralgia Patients

open access: yesAnnals of Neurology, EarlyView.
Proposed model of exosome‐mediated neuronal dysfunction in post‐herpetic neuralgia (PHN). (1) Circulating, non‐pathogenic exosomes maintain homeostatic processes in healthy skin, where sensory nerve fibers innervate the epidermis and dermis. (2) During acute zoster, reactivating varicella zoster virus (VZV) travels down neurites to the skin causing ...

Enhancing the Secretion Systems: Genetic Engineering of Super Bioagents for Effective Plant Disease Control

open access: yesBiotechnology and Bioengineering, EarlyView.
Genetic engineering (GE) overcomes BCA limits, enabling robust, scalable crop protection. “Super Bioagents” (SBs) use optimized SSs to enhance bioactive molecule delivery. Optimizing SSs enhance precise, sustainable effector deployment for stable disease suppression. SBs use microbiome‐informed design for scalable, next‐gen sustainable crop protection.

Wavelength-division multiplexing Fresnel transform encoding of time-varying signals

open access: yes, 2008
We study the wavelength-division multiplexing implementation of the recently proposed temporal Fresnel transform encoding technique, in order to evaluate its potential application for secure data transmission in short-haul fiber optic links.

Photothermal bubble: Dynamics, manipulation, and applications

open access: yesDroplet, EarlyView.
As a versatile platform for bubble manipulation, photothermal techniques empower diverse operations: planar translation by scanning the laser spot, sustained periodic bouncing from competing thermal and hydrodynamic flows, and even guided 3D trajectories achieved by tailoring the heating configuration.
