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...

Inhibitory feedback control of NF-κB signalling in health and disease.
Cells must adapt to changes in their environment to maintain cell, tissue and organismal integrity in the face of mechanical, chemical or microbiological stress. Nuclear factor-κB (NF-κB) is one of the most important...

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...

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...
A Comparison of the Structural Chemistry of Scandium, Yttrium, Lanthanum and Lutetium
Data deposited in the Cambridge Structural Database (CSD) for compounds of scandium, yttrium, lanthanum and lutetium(III) have been analysed to assess the structural similarities of complexes of the different metal ions. 29 sets...

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...
Evidence for a disordered critical point in a glass-forming liquid
Using computer simulations of an atomistic glass-forming liquid, we investigate the fluctuations of the overlap between a fluid configuration and a quenched reference system. We find that large fluctuations of the overlap...
Learning from sensory predictions for autonomous and adaptive exploration of object shape with a tactile robot
Humans use information from sensory predictions, together with
current observations, for the optimal exploration and recognition of
their surrounding environment. In this work, two novel adaptive
perception...

Feeling the Shape
Autonomous exploration in robotics is a crucial feature to achieve robust and safe systems capable to interact with and recognize their surrounding environment. In this paper, we present a method for object recognition using a...

Predicting the self-assembly of a model colloidal crystal
We investigate the self-assembly (crystallisation) of particles with hard cores and isotropic, square-well interactions, using a Monte Carlo scheme to simulate overdamped Langevin dynamics. We measure correlation and response...
Controlling crystal self-assembly using a real-time feedback scheme
We simulate crystallisation of hard spheres with short-ranged attractive potentials as a model self-assembling system. Using measurements of correlation and response functions, we develop a method whereby the interaction...

Quantifying reversibility in a phase-separating lattice gas
We present dynamic measurements of a lattice gas during phase separation, which we use as an analogy for self-assembly of equilibrium ordered structures. We use two approaches to quantify the degree of reversibility of this...

Rectification in a mixture of active and passive particles subject to a ratchet potential
Abstract
We study by simulation a mixture of active (run-and-tumble) and passive (Brownian) particles with repulsive exclusion interactions in one dimension, subject to a ratchet...
