Gromov–Witten theory and invariants of matroids
Abstract We use techniques from Gromov–Witten theory to construct new invariants of matroids taking value in the Chow groups of spaces of rational curves in the permutohedral toric variety. When...

3D intrinsic shapes of quiescent galaxies in observations and simulations
Junkai Zhang, Stijn Wuyts, Callum Witten, Charlotte R. Avery, Lei Hao, Raman Sharma, Juntai Shen, Jun Toshikawa, Carolin Villforth
Jul 31, 2022
We study the intrinsic 3D shapes of quiescent galaxies o v er the last half of cosmic history based on their axial ratio distribution. To this end, we construct a sample of unprecedented size, e xploiting multiwav elength u...

Extensive ground state entropy in supersymmetric lattice models
Hendrik Van Eerten
Dec 01, 2005
We present the result of calculations of the Witten index for a supersymmetric lattice model on lattices of various type and size. Because the model remains supersymmetric at finite lattice size, the Witten index can be...

Evidence for a Low Lyman Continuum Escape Fraction in Three Massive, Ultraviolet-bright Galaxies at z > 7
Abstract
Although low-mass star-forming galaxies are the leading candidates of the reionization process, we cannot conclusively rule out high-mass star-forming galaxies as...
Realism, Liberalism and the Democratic Peace
Callum Petrie Carmichael
Sep 25, 2012
Much has been written both against, and in favour of, the evidence for the democratic peace theory. Advocates point to the relatively strong empirical evidence provided by two centuries virtually free of war between...

Liberal Theory and the European Union
Callum Petrie Carmichael
Nov 12, 2013
Liberal theory in international relations predicts that states who are linked by trade, membership in international organizations, and shared democratic government will tend to
become increasingly peaceful and cooperative. In...

Assessment of direct and indirect associations between children active school travel and environmental, household and child factors using structural equation modelling.
BACKGROUND: Active school travel (AST) is influenced by multiple factors including built and social environments, households and individual variables. A holistic theory such as Mitra's Behavioural Model of School Transportation...

Defining the Protease and Protease Inhibitor (P/PI) Proteomes of Healthy and Diseased Human Skin by Modified Systematic Review.
Callum Stewart-McGuinness, Christopher I Platt, Matiss Ozols, Brian Goh, Tamara W Griffiths, Michael J Sherratt
Apr 24, 2022
Proteases and protease inhibitors (P/PIs) are involved in many biological processes in human skin, yet often only specific families or related groups of P/PIs are investigated. Proteomics approaches, such as mass spectrometry...
Counter-Theatre during the 1797 Fleet Mutinies
Abstract In the spring of 1797, when French invasion appeared likely, the Spithead and Nore mutinies successively immobilized the two Royal Navy fleets responsible for home defence. The Spithead...

Magnetic and superconducting phase diagrams and transition temperatures predicted using text mining and machine learning
Abstract: Predicting the properties of materials prior to their synthesis is of great importance in materials science. Magnetic and superconducting materials exhibit a number of unique properties that make them useful in a wide...
Auto-generated materials database of Curie and Néel temperatures via semi-supervised relationship extraction.
Large auto-generated databases of magnetic materials properties have the potential for great utility in materials science research. This article presents an auto-generated database of 39,822 records containing chemical compounds...

Effect of medical school attended on the chances of successfully embarking on a clinical-academic career in the UK.
PURPOSE OF THE STUDY: This study aimed to investigate whether, in the UK, medical school attended influences the propensity to apply to and be successful in obtaining an offer from the Academic Foundation Programme (AFP), thus...

3-D Inorganic Crystal Structure Generation and Property Prediction via Representation Learning
Generative models have been successfully used to synthesize completely novel images, text, music and speech. As such, they present an exciting opportunity for the design of new materials for functional applications. So far...
Gauge theory and boundary integrability. Part II. Elliptic and trigonometric cases
Abstract: We consider the mixed topological-holomorphic Chern-Simons theory introduced by Costello, Yamazaki & Witten on a ℤ2 orbifold. We use this to construct semi- classical solutions of the boundary Yang-Baxter equation in...
