Synchrotron-based visualization and segmentation of elastic lamellae in the mouse carotid artery during quasi-static pressure inflation [PDF]

, 2018
This dataset contains images that were obtained during quasi-static pressure inflation of mouse carotid arteries. Images were taken with phase propagation imaging at the X02DA TOMCAT beamline of the Swiss Light Source synchrotron at the Paul Scherrer ...

Unveiling a novel metal-to-metal transition in LuH2: Critically challenging superconductivity claims in lutetium hydrides

Matter and Radiation at Extremes
Following the recent report by Dasenbrock-Gammon et al. [Nature 615, 244–250 (2023)] of near-ambient superconductivity in nitrogen-doped lutetium trihydride (LuH3−δNε), significant debate has emerged surrounding the composition and interpretation of the ...

Pressure-induced robust emission in a zero-dimensional hybrid metal halide (C9NH20)6Pb3Br12

Matter and Radiation at Extremes, 2021
Zero-dimensional (0D) hybrid metal halides are under intensive investigation owing to their unique physical properties, such as the broadband emission from highly localized excitons that is promising for white-emitting lighting.

From Kinematics To Dynamics: Estimating Center of Pressure and Base of Support from Video Frames of Human Motion [PDF]

arXiv, 2020
To gain an understanding of the relation between a given human pose image and the corresponding physical foot pressure of the human subject, we propose and validate two end-to-end deep learning architectures, PressNet and PressNet-Simple, to regress foot pressure heatmaps (dynamics) from 2D human pose (kinematics) derived from a video frame.

Metallic Icosahedron Phase of Sodium at Terapascal Pressures [PDF]

Physical Review Letters 114, 125501, (2015), 2015
Alkali metals exhibit unexpected structures and electronic behavior at high pressures. Compression of metallic sodium (Na) to 200 GPa leads to the stability of a wide-band-gap insulator with the double hexagonal hP4 structure. Post-hP4 structures remain unexplored, but they are important for addressing the question of the pressure at which Na reverts ...

High-pressure thermoelasticity of body-centered-cubic tantalum [PDF]

Physical Review B, 2002
We have investigated the thermoelasticity of body-centered cubic (bcc) tantalum from first principles by using the linearized augmented plane wave (LAPW) and mixed--basis pseudopotential methods for pressures up to 400 GPa and temperatures up to 10000 K.

Static solutions of the spherically symmetric Vlasov-Einstein system

, 1993
The Vlasov-Einstein system describes the evolution of an ensemble of particles (such as stars in a galaxy, galaxies in a galaxy cluster etc.) interacting only by the gravitational field which they create collectively and which obeys Einstein's field ...

Retention of high-pressure solution-processable metastable phase to ambience via differential sublattice rigidity for broadband photodetectors

Nature Communications
Materials science exploits only properties that are available at ambience. Therefore, although high-pressure changes the physical state of all condensed matter, most of the extraordinary properties discovered vanish after decompression and cannot be ...

Predicted formation of superconducting platinum-hydride crystals under pressure in the presence of molecular hydrogen [PDF]

Phys. Rev. Lett. 107, 117002 (2011), 2011
Noble metals adopt close-packed structures at ambient pressure and rarely undergo structural transformation at high pressures. Platinum (Pt), in particular, is normally considered to be unreactive and is therefore not expected to form hydrides under pressure. We predict that platinum hydride (PtH) has a lower enthalpy than its constituents solid Pt and
