Probing the metallicity and ionization state of the circumgalactic medium at z~6 and beyond with OI absorption (2013)
Journal Article

Low-ionization metal absorption due to O I has been identified as an important probe of the physical state of the intergalactic/circumgalactic medium at the tail end of reionization. We use here high-resolution hydrodynamic simulations to interpret t... Read More about Probing the metallicity and ionization state of the circumgalactic medium at z~6 and beyond with OI absorption.

Strain-mediated coupling in a quantum dot-mechanical oscillator hybrid system (2013)
Journal Article

Recent progress in nanotechnology has allowed the fabrication of new hybrid systems in which a single two-level system is coupled to a mechanical nanoresonator. In such systems the quantum nature of a macroscopic degree of freedom can be revealed and... Read More about Strain-mediated coupling in a quantum dot-mechanical oscillator hybrid system.

A randomised trial of ondansetron for the treatment of irritable bowel syndrome with diarrhoea (2013)
Journal Article

Background: Irritable bowel syndrome with diarrhoea (IBS-D) is particularly debilitating due to urgency and episodic incontinence.

The one-dimensional Lyα forest power spectrum from BOSS (2013)
Journal Article

We have developed two independent methods for measuring the one-dimensional power spectrum of the transmitted flux in the Lyman-α forest. The first method is based on a Fourier transform and the second on a maximum-likelihood estimator. The two metho... Read More about The one-dimensional Lyα forest power spectrum from BOSS.

The relationship between MEG and fMRI (2013)
Journal Article

In recent years functional neuroimaging techniques such as fMRI, MEG, EEG and PET have provided researchers with a wealth of information on human brain function. However none of these modalities can measure directly either the neuro-electrical or ne... Read More about The relationship between MEG and fMRI.

Ensemble fermions for electroweak dynamics and the fermion preheating temperature (2013)
Journal Article

We refine the implementation of ensemble fermions for the electroweak sector of the Standard Model, introduced previously. We consider the behavior of different observables as the size of the ensemble is increased and show that the dynamics converges...

Manipulating the Conformation of Single Organometallic Chains on Au(111) (2013)
Journal Article

The conformations of organometallic polymers formed via the bottom-up assembly of monomer units on a metal surface are investigated, and the relationship between the adsorption geometry of the individual monomer units, the conformational structure of...

Scanning probe image wizard: a toolbox for automated scanning probe microscopy data analysis (2013)
Journal Article

We describe SPIW (scanning probe image wizard), a new image processing toolbox for SPM (scanning probe microscope) images. SPIW can be used to automate many aspects of SPM data analysis, even for images with surface contamination and step edges prese...

Interplay between Coulomb and Jahn-Teller effects in icosahedral systems with triplet electronic states coupled to h-type vibrations (2013)
Journal Article

We will consider the role played by electron-vibration and electron-electron interactions, through Jahn-Teller (JT) and Coulomb interactions, respectively, in icosahedral systems in which triplet electronic states are coupled to hg-type vibrations. S... Read More about Interplay between Coulomb and Jahn-Teller effects in icosahedral systems with triplet electronic states coupled to h-type vibrations.

Novel MRI tests of orocecal transit time and whole gut transit time: studies in normal subjects (2013)
Journal Article

Background: Colonic transit tests are used to manage patients with Functional Gastrointestinal Disorders. Some tests used expose patients to ionizing radiation. The aim of this study was to compare novel magnetic resonance imaging (MRI) tests for mea...

Pulmonary MRI contrast using Surface Quadrupolar Relaxation (SQUARE) of hyperpolarized 83Kr (2013)
Journal Article

Hyperpolarized 83Kr has previously been demonstrated to enable MRI contrast that is sensitive to the chemical composition of the surface in a porous model system. Methodological advances have lead to a substantial increase in the 83Kr hyperpolarizati...

Gravitational waves from oscillon preheating (2013)
Journal Article

Oscillons are long-lived, localized excitations of nonlinear scalar fields which may be copiously produced during preheating after inflation, leading to a possible oscillon-dominated phase in the early Universe. For example, this can happen after axi... Read More about Gravitational waves from oscillon preheating.
