Balanced Families of Perfect Hash Functions and Their Applications [PDF]

, 2007
The construction of perfect hash functions is a well-studied topic. In this paper, this concept is generalized with the following definition. We say that a family of functions from $[n]$ to $[k]$ is a $\delta$-balanced $(n,k)$-family of perfect hash ...

Quantum Key Distribution with Blind Polarization Bases [PDF]

, 2005
We propose a new quantum key distribution scheme that uses the blind polarization basis. In our scheme the sender and the receiver share key information by exchanging qubits with arbitrary polarization angles without basis reconciliation.

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 ...

Development, external validation and integration into clinical workflow of machine learning models to support pre‐operative assessment in the UK

Anaesthesia, EarlyView.
Summary Introduction Demand for surgical treatment is growing and patient complexity is increasing. The NHS England standard contract now requires that pre‐operative services risk stratify and optimise patients awaiting surgery. However, current pre‐operative workflows (whether electronic or paper‐based) remain based primarily on resource‐intensive ...

Cache-Oblivious Peeling of Random Hypergraphs

, 2013
The computation of a peeling order in a randomly generated hypergraph is the most time-consuming step in a number of constructions, such as perfect hashing schemes, random $r$-SAT solvers, error-correcting codes, and approximate set encodings.

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 ...
