Initial data for gravity coupled to scalar, electromagnetic and Yang-Mills fields [PDF]

, 1998
We give ansatze for solving classically the initial value constraints of general relativity minimally coupled to a scalar field, electromagnetism or Yang-Mills theory. The results include both time-symmetric and asymmetric data.

Bistability in the Tunnelling Current through a Ring of $N$ Coupled Quantum Dots

, 2012
We study bistability in the electron transport through a ring of N coupled quantum dots with two orbitals in each dot. One orbital is localized (called b orbital) and coupling of the b orbitals in any two dots is negligible; the other is delocalized in ...

A Graph-Based Semantics Workbench for Concurrent Asynchronous Programs [PDF]

, 2016
A number of novel programming languages and libraries have been proposed that offer simpler-to-use models of concurrency than threads. It is challenging, however, to devise execution models that successfully realise their abstractions without forfeiting ...

Levy statistics and anomalous transport in quantum-dot arrays

, 2005
A novel model of transport is proposed to explain power law current transients and memory phenomena observed in partially ordered arrays of semiconducting nanocrystals.

Hydrological controls on river network connectivity [PDF]

, 2019
This study proposes a probabilistic approach for the quantitative assessment of reach- and network-scale hydrological connectivity as dictated by river flow space–time variability. Spatial dynamics of daily streamflows are estimated based on climatic and

Making teaching an attractive profession: What are the challenges and opportunities for minority ethnic teachers in England?

British Educational Research Journal, EarlyView.
Abstract This paper explores the challenges and opportunities surrounding the recruitment and retention of minority ethnic teachers in England. Drawing on interview data from 33 teachers and school leaders of diverse ethnic backgrounds, it investigates whether racialised barriers identified in earlier research have shifted in the current context of ...

Partonic quasi-distributions of the pion in chiral quark models

, 2017
The evaluation of partonic distributions presents a challenge for QCD, and in particular for its Euclidean lattice realization. Recently, objects called quasi-distributions (which become standard distributions in a limit of the longitudinal momentum of ...

Reuse of Water as Part of a Water Sustainability Strategy: Experiences of Germany and Poland

Corporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT Wastewater can provide an alternative supply of scarce water resources, particularly for operations that do not require high‐quality water. The uptake in wastewater usage is likely to be driven by a combination of public and private sector actors via internal actions and external collaborations.

AI‐based localization of the epileptogenic zone using intracranial EEG

Epilepsia Open, EarlyView.
Abstract Artificial intelligence (AI) is rapidly transforming our lives. Machine learning (ML) enables computers to learn from data and make decisions without explicit instructions. Deep learning (DL), a subset of ML, uses multiple layers of neural networks to recognize complex patterns in large datasets through end‐to‐end learning.
