Protocol‐Agnostic Meta Key Distribution for Encrypted Wireless Communications Enabled by Space‐Time‐Coding Metasurface

Advanced Science, EarlyView.
This paper presents a programmable metasurface‐based Meta Key Distribution (MKD) system for secure, protocol‐independent key exchange in indoor wireless settings. By embedding entropy into the wireless channel, it enables lightweight, compatible cryptographic key generation.

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 ...

Implicit Promises and the Timing of Defined‐Benefit Pension Plan Freezes

Financial Management, EarlyView.
ABSTRACT Firms time defined‐benefit (DB) plan freezes after CEO turnovers to protect CEO retirement benefits from cost cuts affecting the wider workforce. We document a significant increase in voluntary CEO turnovers just before the freeze, without notable post‐freeze changes.

Fast Locality-Sensitive Hashing Frameworks for Approximate Near Neighbor Search

, 2018
The Indyk-Motwani Locality-Sensitive Hashing (LSH) framework (STOC 1998) is a general technique for constructing a data structure to answer approximate near neighbor queries by using a distribution $\mathcal{H}$ over locality-sensitive hash functions ...

The Making of the EU's Geoeconomic ‘Bazooka’: The Anti‐Coercion Instrument and the Role of Think Tanks in European Union Foreign Policy

JCMS: Journal of Common Market Studies, EarlyView.
Abstract The Anti‐Coercion Instrument (ACI), the most powerful tool in the EU's geoeconomic arsenal, has its origins in the first Trump US presidency and has recently been brandished again as a potential response to Trump's coercive tariffs. Its centrality to the EU's ‘geoeconomic turn’ and the twists and turns of its legislative history have been ...

High-dimensional approximate nearest neighbor: k-d Generalized Randomized Forests [PDF]

, 2016
We propose a new data-structure, the generalized randomized kd forest, or kgeraf, for approximate nearest neighbor searching in high dimensions. In particular, we introduce new randomization techniques to specify a set of independently constructed trees ...
