Rethinking d/Development
A dialectical relationship between ‘big D’ Development (broadly, the formal interventionist, international Development sector) and little ‘d’ development (the immanent structures and processes of capitalism) is a concept widely...
Direct age constraints on the magnetism of Jack Hills zircon.

Feb 09, 2023
A potential record of Earth's magnetic field going back 4.2 billion years (Ga) ago is carried by magnetite inclusions in zircon grains from the Jack Hills. This magnetite may be secondary in nature, however, meaning that the...

Clinical and electrophysiological characterization of myokymia and neuromyotonia in Jack Russell Terriers.
AE Vanhaesebrouck, I Van Soens, L Poncelet, L Duchateau, S Bhatti, I Polis, S Diels, L Van Ham
Jul 03, 2019
BACKGROUND: Generalized myokymia and neuromyotonia (M/NM) in Jack Russell Terriers (JRTs) is related to peripheral nerve hyperexcitability syndrome in humans, a symptom complex resulting from diverse etiologies. OBJECTIVE...
How contaminated with ammunition-derived lead is meat from European small game animals? Assessing and reducing risks to human health.
Small game animals are generally hunted with lead gunshot which often fragments causing elevated lead concentrations in meat and presenting health risks to frequent consumers and vulnerable groups. We reviewed three decades of...

The time of origin of the geodynamo has important implications for the thermal evolution of the planetary interior and the habitability of early Earth. It has been proposed that detrital zircon grains from Jack Hills, Western...

Interventions targeting working memory in 4-11 year olds within their everyday contexts
It has been suggested that diverse interventions applied within children's everyday contexts have the potential to improve working memory (WM) and produce transfer to real-world skills but little is known about the effectiveness...
Ergodicity and large deviations in physical systems with stochastic dynamics
Robert L. Jack
Jun 06, 2020
Abstract: In ergodic physical systems, time-averaged quantities converge (for large times) to their ensemble-averaged values. Large deviation theory describes rare events where these time averages differ significantly from the...
Random pinning in glassy spin models with plaquette interactions
We use a random pinning procedure to study amorphous order in two glassy spin models. On increasing the concentration of pinned spins at constant temperature, we find a sharp crossover (but no thermodynamic phase transition)...
Investigating amorphous order in stable glasses by random pinning
We investigate stable glassy states that are found when glass-forming liquids are biased to lower than average dynamical activity. By pinning the positions of randomly chosen particles, we show that many-body correlations in...
Dynamical phase transitions in supercooled liquids
We study dynamical phase transitions in a model supercooled liquid. These transitions occur in ensembles of trajectories that are biased towards low (or high) dynamical activity. We compare two different measures of activity...
Phase transition for quenched coupled replicas in a plaquette spin model of glasses
We study a three-dimensional plaquette spin model whose low temperature dynamics is glassy, due to localized defects and effective kinetic constraints. The thermodynamics of this system is smooth at all temperatures. We show...
A classroom intervention targeting working memory, attention and language skills
BACKGROUND: International debate around the best models of speech and language therapy provision for children with language disorders has highlighted the need for research into classroom-based approaches and intervention dosage....

Optimising self-assembly through time-dependent interactions
We demonstrate a simple method by which time-dependent interactions can be exploited to improve self-assembly in colloidal systems. We apply this method to two systems: a model colloid with a short-ranged attractive potential...

Large deviations in models of growing clusters with symmetry-breaking transitions.
Robert L Jack
Sep 03, 2019
We analyze large deviations of the magnetization in two models of growing clusters. The models have symmetry-breaking transitions, so the typical magnetization of a growing cluster may be either positive or negative, with equal...
Tracer dynamics in one dimensional gases of active or passive particles
Abstract
We consider one-dimensional systems comprising either active run-and-tumble particles (RTPs) or passive Brownian random walkers. These particles are either noninteracting...
