Symbol Detection of Ambient Backscatter Systems with Manchester Coding

, 2018
Ambient backscatter communication is a newly emerged paradigm, which utilizes the ambient radio frequency (RF) signal as the carrier to reduce the system battery requirement, and is regarded as a promising solution for enabling large scale deployment of ...

Random Time‐Space Coding Metasurfaces for Spatial Control of the Temporal Statistics of Electromagnetic Fields

Advanced Science, EarlyView.
A probabilistic framework based on random time‐space coding metasurfaces enables control of the spatial distribution of electromagnetic fields temporal statistics. By tailoring the marginal and joint distributions of random codes, electromagnetic fields with desired mean and variance patterns are realized, enabling simultaneous transmission and jamming.

Kinesin‐Induced Buckling Reveals the Limits of Microtubule Self‐Repair

Advanced Science, EarlyView.
This study shows that kinesin‐driven buckling induces extensive microtubule lattice damage that often exceeds intrinsic self‐repair and leads to filament failure. While curvature, motor motility, and force individually cause limited damage, their combination overwhelms repair.

A semi-deterministic channel model for VANETs simulations

, 2010
In this paper we propose a semi-deterministic channel propagation model for VANETs (Vehicular Ad-hoc NETworks) called UM-CRT. It is based on CRT (Communication Ray Tracer) and SCME-UM (Spatial Channel Model Extended - Urban Micro) which are respectively a deterministic channel simulator and a statistical channel model.

Deterministic Ray Tracing: A Promising Approach to THz Channel Modeling in 6G Deployment Scenarios

IEEE Communications Magazine
Terahertz (THz) communication is considered to be a key enabling technology for 6G due to its abundant available spectrum resources. One pre-requisite for implementing THz communication systems is to understand and model the THz radio channel in 6G ...

Semiconducting Polymer Nanoparticles Enable Light‐Controlled Bidirectional Modulation of Nitric Oxide in Endothelial Cells

Advanced Science, EarlyView.
Bimodal modulation of nitric oxide in endothelial cells is achieved by light‐sensitive polymer nanoparticles. In dark, P3HT/PEDOT:PSS NPs boost intracellular ·NO, upregulate both endothelial and induced nitric oxide synthase, and drive a metabolic shift toward glycolysis.

Sub‐Unit‐Cell Logic Governs Transport in TPMS Architectures

Advanced Science, EarlyView.
ABSTRACT Next‐generation energy, thermal, and chemical systems require architectures capable of highly efficient transport across multiple length scales. Triply periodic minimal surfaces (TPMS), first conceptualized in 1865, offer inherently scalable geometries with exceptional transport potential, yet mechanistic links between topology and performance

An Analytical Link Loss Model for On-Body Propagation Around the Body Based on Elliptical Approximation of the Torso with Arms' Influence Included

, 2013
An analytical model for estimating the link loss for the on-body wave propagation around the torso is presented. The model is based on the attenuation of the creeping waves over an elliptical approximation of the human torso and includes the influence of
