This collected volume is written in honour of Allen G. Debus (1926–2009), the famous historian of science. Trained as a chemist, his interest in the history of science and chemistry would guide his research and his output. As...
The Unmanned Aerial Vehicle Routing and Trajectory Optimisation Problem, a Taxonomic Review
Over the past few years, Unmanned Aerial Vehicles (UAVs) have become more and more popular. The complexity of routing UAVs has not been fully investigated in the literature. In this paper, we provide a formal definition of the...
Insect Host Seeking: Investigations into the Molecular Mechanisms of Chemosensation
Walton D. Jones
Jan 01, 0001
Among other functions, chemosensory systems play a crucial role in the host-seeking behaviors of insects that allow them to find their preferred food sources. Quite often, however, these host-seeking behaviors have a negative...

Glider Routing and Trajectory Optimisation in disaster assessment
In this paper, we introduce the Glider Routing and Trajectory Optimisation Problem (GRTOP), the problem of simultaneously finding optimal routes and trajectories for a fleet of gliders with the aim of surveying a set of...

Serous borderline ovarian tumours
Serous borderline ovarian tumours (SBOTs) are an intermediate group of neoplasms, which have features between benign and malignant ovarian tumours and for which, fertility-sparing surgery can be offered. MRI in imaging of SBOTs...
Genomic Relationships, Novel Loci, and Pleiotropic Mechanisms across Eight Psychiatric Disorders
Esther Walton
Dec 12, 2019
Genetic influences on psychiatric disorders transcend diagnostic boundaries, suggesting substantial pleiotropy of contributing loci. However, the nature and mechanisms of these pleiotropic effects remain unclear. We performed...
Framing disputes and organizational legitimation
Oliver Walton
May 01, 2015
The ending of the war in Sri Lanka in 2009 led to significant changes in the political strategies pursued by Sri Lankan Tamil diaspora groups in the UK. One contentious feature of these groups’ campaigns has been their use of...
Ruthenium catalyzed remote C4-selective C–H functionalisation of carbazoles via σ-activation
Jamie A. Leitch, Callum J. Heron, Janette Mcknight, Gabriele Kociok-Köhn, Yunas Bhonoah, Christopher G. Frost
Dec 18, 2017
We report the C4-selective C–H alkylation of carbazole derivatives furnished with a pyrimidine directing group at N9. This was realized using ruthenium catalyzed r-activation methodology, whereby C–H activation at C1 enables the...
Association between DNA methylation and ADHD symptoms from birth to school age
Esther Walton
Nov 12, 2020
Attention-deficit and hyperactivity disorder (ADHD) is a common childhood disorder with a substantial genetic component. However, the extent to which epigenetic mechanisms play a role in the etiology of the disorder is unknown....

Vortex counting and the quantum Hall effect
Edward Walton
Feb 19, 2022
We provide evidence for conjectural dualities between nonrelativistic
Chern-Simons-matter theories and theories of (fractional, nonAbelian) quantum
Hall fluids in $2+1$ dimensions. At low temperatures, the dynamics...
