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 ...

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.

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 ...

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

Greens in Regulation: Biodiversity Strategy Implementation Across the Golf Industry

Business Strategy and the Environment, EarlyView.
ABSTRACT Although much of the business and biodiversity literature focuses on extractive industries, we turn our attention to the golf industry. Golf courses occupy millions of acres globally, yet biodiversity strategy implementation across the golf industry remains understudied.

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 ...

‘Value for Whom, by Whom’: Investigating Value Constructs in Non-Profit Project Portfolios [PDF]

, 2016
In most non-profit organisations (NPOs), there are multiple programs, projects or initiatives running simultaneously. The management of multiple projects in organisations can be coined as project portfolio management (PPM) (Archer & Ghasemzadeh 1999;

Statistical Discrimination of Urinary Steroid Biomarkers in the Athlete Biological Passport: A Novel Approach to an Abnormal Steroid Profile Score (ASPS)

Drug Testing and Analysis, EarlyView.
The study developed a single Abnormal Steroid Profile Score (ASPS) to improve interpretation of the Athlete Biological Passport steroid module. Using Bayesian modelling and logistic regression, biomarker patterns from laboratory and doping control data successfully discriminated between doped and clean individuals, with improved classification ...

Abstract Learning Frameworks for Synthesis

, 2016
We develop abstract learning frameworks (ALFs) for synthesis that embody the principles of CEGIS (counter-example based inductive synthesis) strategies that have become widely applicable in recent years. Our framework defines a general abstract framework
