Small Science, EarlyView.This study determines the effects of melt conditions and time on agZIF‐62's pore volume, accessible porosity, morphology, and coalescence for controlled production of ZIF‐62 glasses. Glasses derived from metal‐organic frameworks (MOFs) combine the processing benefits of glassy materials with the accessible and selective porosity of MOFs, with potential

A Bridge Transformer Network With Deep Graph Convolution for Hyperspectral Image Classification
CAAI Transactions on Intelligence Technology, EarlyView.ABSTRACT Transformers have been widely applied to hyperspectral image classification, leveraging their self‐attention mechanism for powerful global modelling. However, two key challenges remain as follows: excessive memory and computational costs from calculating correlations between all tokens (especially as image size or spectral bands increase) and ...

High Voltage, EarlyView.ABSTRACT This study explores exciting state species and reaction pathways in positive leaders to better understand the breakdown mechanisms of long air gap discharges and natural lightning. Emission spectra from an unstable positive leader in a 1 m rod‐plate air gap under switching impulse voltages were observed, spanning 300–800 nm.

YOLO‐GDCNN: Real‐Time Operating Point Detection for Live Working Robots in the Power Industry
High Voltage, EarlyView.ABSTRACT In the power industry maintenance, the capability of live working robots to detect and operate with power components in real time is paramount. This paper proposes a cascaded detection framework for real‐time detection of live working operation points, named YOLO‐GDCNN. The framework consists of two parts.

Archaeometry, EarlyView.ABSTRACT Provenance reconstruction using strontium and lead stable isotopes can produce complex multidimensional fingerprints, challenging traditional methods. Identifying nonlocals, who migrated between sites, is a major task. Migrants are identifiable by divergent multi‐isotope fingerprints due to isotopic mixing between origin and destination sites.

Semipositone boundary value problems with nonlocal, nonlinear boundary conditions
Advances in Differential Equations, 2015 We demonstrate the existence of at least one positive solution to \begin{equation} \begin{split} -y''(t)& =\lambda f(t,y(t))\text{, }t\in(0,1)\\ y(0)& =H(\varphi(y))\text{, }y(1)=0,\notag \end{split} \end{equation} where $H : \mathbb{R}\rightarrow\mathbb{R}$ is a continuous function and $\varphi : \mathcal{C}([0,1])\rightarrow\mathbb{R}$ is a linear ...
