Neuromorphic Deep‐Ultraviolet Signal Processing Using a‐Ga2O3

Advanced Electronic Materials, EarlyView.
Amorphous gallium oxide (a‐Ga2O3) metal‐semiconductor‐metal photodetectors exhibit paired‐pulse facilitation arising from charge trapping. Four‐bit UVC binary sequences are encoded into separable conductance states. An RC equivalent circuit model of the device is deployed in single‐ and composite multi‐node reservoir computers, achieving ∼95% accuracy ...

Redesigning Interlayers for Anode‐Free Batteries: Harnessing Continuity and Metal Inventory

Advanced Energy Materials, EarlyView.
Interlayers for anode‐free batteries must provide continuous interfacial coverage while remaining thin enough to preserve the finite cathode‐derived active‐metal inventory. This Perspective couples thin‐film closure with stoichiometric active‐metal consumption to reveal practical design windows across chemistry, substrate roughness, cathode loading ...

Overcoming the Phase Discontinuity Problem in RIS Optimization: A Robust and Scalable Phase‐Aware Deep Regression Framework via Hybrid CNN–LSTM Architecture

Advanced Intelligent Systems, EarlyView.
The phase discontinuity problem—where the cyclic nature of phase angles causes catastrophic errors near the ±π boundary—is a fundamental obstacle in learning‐based reconfigurable intelligent surface (RIS) optimization. A phase‐aware hybrid CNN–LSTM framework resolves this by decomposing phase predictions into sine–cosine components, mapping circular ...

Joint Full-Duplex/Half-Duplex Transmission-Switching Scheduling and Transmission-Energy Allocation in Cognitive Radio Networks with Energy Harvesting

Sensors, 2018
The full-duplex transmission protocol has been widely investigated in the literature in order to improve radio spectrum usage efficiency. Unfortunately, due to the effect of imperfect self-interference suppression, the change in transmission power and ...

The ORCA‐TWIN qCMOS Experiment I. Science Case and Commissioning at Calar Alto Observatory

Astronomische Nachrichten, EarlyView.
ABSTRACT We describe a pilot study to explore a new generation of fast and low noise CMOS image sensors for time domain astronomy, using two remote telescopes with a baseline of 1635 km. The experiment involves direct imaging with novel qCMOS image sensor technology that combines fast readout with sub‐electron readout noise.

Creating space(s) for learning in prison: Developing an andragogical framework

British Educational Research Journal, EarlyView.
Abstract Learning in prison is too often excluded from wider discussions of educational experiences, processes and impact. This paper proposes, for the first time, an iterative andragogical framework to conceptualise learning spaces within prison contexts.
