Machine learning Calabi-Yau metrics

- A. Ashmore, Yanghui He, B. Ovrut
- Mathematics, Physics
- 18 October 2019

We apply machine learning to the problem of finding numerical Calabi-Yau metrics. Building on Donaldson's algorithm for calculating balanced metrics on K\"ahler manifolds, we combine conventional… Expand

Chemists and "the public": IUPAC's role in achieving mutual understanding (IUPAC Technical Report)

- P. Mahaffy, A. Ashmore, Bob Bucat, C. Do, Megan Rosborough
- Chemistry
- 2008

This report informs IUPAC's efforts to enhance the public understanding of and appreciation for chemistry by evaluating IUPAC's mandate, strengths, and weaknesses, and providing insights from a… Expand

Calabi-Yau Three-folds: Poincare Polynomials and Fractals

- A. Ashmore, Y. He
- Mathematics, Physics
- 7 October 2011

We study the Poincar´e polynomials of all known Calabi-Yau three-folds as constrained polynomials of Littlewood type, thus generalising the wellknown investigation into the distribution of the Euler… Expand

Eigenvalues and eigenforms on Calabi-Yau threefolds

- A. Ashmore
- Physics, Mathematics
- 27 November 2020

We present a numerical algorithm for computing the spectrum of the Laplace-de Rham operator on Calabi-Yau manifolds, extending previous work on the scalar Laplace operator. Using an approximate… Expand

Line Bundle Hidden Sectors for Strongly Coupled Heterotic Standard Models

- A. Ashmore, Sebastian Dumitru, B. Ovrut
- Physics
- 11 March 2020

The compactification from the eleven-dimensional Ho\v{r}ava-Witten orbifold to five-dimensional heterotic M-theory on a Schoen Calabi-Yau threefold is reviewed, as is the specific $SU(4)$ vector… Expand

Generalising G 2 geometry : involutivity , moment maps and moduli

We analyse the geometry of generic Minkowski N = 1, D = 4 flux compactifications in string theory, the default backgrounds for string model building. In M-theory they are the natural string theoretic… Expand

COCCYGECTOMY FOR COCCYDYNIA: A CASE SERIES WITH HYPERMOBILE JOINTS AND ANALYSIS

- D. Thavarajah, G. Powell, A. Ashmore, A. Floyd
- Medicine
- 1 April 2012

Coccygectomy, surgical excision of the coccyx, may be used to treat coccydynia, a chronic and disabling condition of the lowest part of the spine. It is a controversial and infrequently performed… Expand

FABRIC BALACLAVAS VS SURGEONS HOODS- DO THEY MAKE A DIFFERENCE TO BACTERIAL SHEDDING IN LAMINAR FLOW THEATRES?

- Odutola, A. Tasker, A. Ashmore, A. Omari
- Mathematics
- 1 May 2009

Aim: To determine the effects of the different types of headgear on bacterial shedding in laminar flow theatres. Material and Methods: Sham experiments were carried out using standard theatre… Expand

Heterotic backgrounds via generalised geometry: moment maps and moduli

- A. Ashmore, C. Strickland-constable, David Tennyson, D. Waldram
- Physics, Mathematics
- 20 December 2019

We describe the geometry of generic heterotic backgrounds preserving minimal supersymmetry in four dimensions using the language of generalised geometry. They are characterised by an $SU(3)\times… Expand

- Physics, Mathematics
- 10 October 2019

We analyse the geometry of generic Minkowski $\mathcal{N}=1$, $D=4$ flux compactifications in string theory, the default backgrounds for string model building. In M-theory they are the natural string… Expand
