Low-temperature transport properties of the intermetallic compound HoAgGe with a kagome spin-ice state [PDF]

Physical review B, 2022
We study the magnetic susceptibility, magnetization, resistivity and thermal conductivity of intermetallic HoAgGe single crystals at low temperatures and in magnetic fields along the $a$ and $c$ axis, while the electric and heat currents are along the $c$

Development of proglacial lakes and evaluation of related outburst susceptibility at the Adygine ice-debris complex, northern Tien Shan

Earth Surface Dynamics, 2019
. The formation and development of glacial lakes in mountainous regions is one of the consequences of glacier recession. Such lakes may drain partially or completely when the stability of their dams is disturbed or as a consequence of impacts. We present

Four‐decade record of pervasive grounding line retreat along the Bellingshausen margin of West Antarctica

Geophysical Research Letters, 2016
Changes to the grounding line, where grounded ice starts to float, can be used as a remotely sensed measure of ice‐sheet susceptibility to ocean‐forced dynamic thinning.

Magnetic anisotropy and debris-dependent rheological heterogeneity within stratified basal ice

Journal of Glaciology, 2019
Basal ice of glaciers and ice sheets frequently contains a well-developed stratification of distinct, semi-continuous, alternating layers of debris-poor and debris-rich ice.

Inhibiting Freeze-Thaw Damage in Cement Paste and Concrete by Mimicking Nature’s Antifreeze

Cell Reports Physical Science, 2020
Summary: Since the 1930s, surfactant-based air-entraining admixtures (AEAs) have been used to mitigate freeze-thaw damage in cementitious materials. While effective, entrained air voids weaken concrete and increase its permeability, thereby increasing ...

Crystal-field states and defect levels in candidate quantum spin ice Ce$_{2}$Hf$_{2}$O$_{7}$ [PDF]

, 2022
We report the synthesis of powder and single-crystal samples of the cerium pyrohafnate and their characterization using neutron diffraction, thermogravimetry and X-ray absorption spectroscopy.

ac Wien Effect in Spin Ice, Manifest in Nonlinear, Nonequilibrium Susceptibility. [PDF]

Physical Review Letters, 2014
The Wien effect is a model process for field-induced charge creation. Here it is derived for a nonelectrical system: the spin ice "magnetolyte"-a unique system showing perfect charge symmetry. An entropic reaction field, analogous to the Jaccard field in

Pathological Insights From Quantitative Susceptibility Mapping and Diffusion Tensor Imaging in Ice Hockey Players Pre and Post-concussion

Frontiers in Neurology, 2018
Myelin sensitive MRI techniques, such as diffusion tensor imaging and myelin water imaging, have previously been used to reveal changes in myelin after sports-related concussions.

Topological-Sector Fluctuations and Curie-Law Crossover in Spin Ice

Physical Review X, 2013
At low temperatures, a spin ice enters a Coulomb phase—a state with algebraic correlations and topologically constrained spin configurations. We show how analytical and numerical approaches for model spin-ice systems reveal a crossover between two Curie ...

Geochemical Evidence for Weathering in Northwestern European Loess on a Sub-millenial Scale During the Last Ice Age [PDF]

This study seeks to determine the extent to which chemostratigraphy can supplement other stratigraphic tools in determining the effects of climate change in loess-palaeosol sequences.
