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...

Peer Influence in Adolescence
The coronavirus disease 2019 (COVID-19) pandemic has resulted in the widespread implementation of social distancing measures. Adhering to social distancing may be particularly challenging for adolescents, for whom interaction...
Amplified Concern for Social Risk in Adolescence
In adolescence, there is a heightened propensity to take health risks such as smoking, drinking or driving too fast. Another facet of risk taking, social risk, has largely been neglected. A social risk can be defined as any...

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...

Discrete and continuous symmetries in monotone Floer theory
Jack Smith
Jul 01, 2020
This paper studies the self-Floer theory of a monotone Lagrangian submanifold
$L$ of a symplectic manifold $X$ in the presence of various kinds of symmetry.
First we suppose $L$ is $K$-homogeneous and compute the image of...

An ALMA 1.3 millimeter Search for Debris Disks around Solar-type Stars in the Pleiades
Abstract
Millimeter emission from debris disks around stars of different ages provides constraints on the collisional evolution of planetesimals. We present ALMA 1.3 millimeter...
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)...
Hydration and N-acetyl-l-cysteine alter the microstructure of human nail and bovine hoof
This work aimed to (a) characterize the microstructure and porosity of human nail and bovine hoof by mercury intrusion porosimetry and SEM image analysis, (b) study the effects of hydration and of N-acetyl-l-cysteine treatment...
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...

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...
Floer Simple Manifolds and L-Space Intervals
An oriented three-manifold with torus boundary admits either no L-space Dehn filling, a unique L-space filling, or an interval of L-space fillings. In the latter case, which we call “Floer simple,” we construct an invariant...
L q -spectra of self-affine measures
Abstract: We study L q -spectra of planar self-affine measures generated by diagonal matrices. We introduce a new technique for constructing and understanding examples based on combinatorial estimates for the exponential growth...

S-2-Amino-4-cyanobutanoic acid (β-cyanomethyl-L-Ala) as an atom-efficient solubilising synthon for L-glutamine
Glutamine (Gln) is often a difficult amino acid to incorporate during solution-phase peptide synthesis, owing to poor solubility and unwanted dehydrations as side-reactions. Current approaches to solving these problems are...
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...
