Quantifying center of pressure variability in chondrodystrophoid dogs [PDF]

The Veterinary Journal, 2017
The center of pressure (COP) position reflects a combination of proprioceptive, motor and mechanical function. As such, it can be used to quantify and characterize neurologic dysfunction. The aim of this study was to describe and quantify the movement of COP and its variability in healthy chondrodystrophoid dogs while walking to provide a baseline for ...

Melting of Iron Explored by Electrical Resistance Jump up to 135 GPa

Geophysical Research Letters, 2021
The melting temperature (Tm) of iron at megabar pressures constrains the Earth's core temperature structure and dynamics. Previous experimental studies demonstrated large discrepancies in Tm at high pressures.

Pressure Engineering Promising Transparent Oxides with Large Conductivity Enhancement and Strong Thermal Stability

Advanced Science, 2022
Transparent conducting oxides (TCO) with high electrical conductivity and high visible light transparency are desired for a wide range of high‐impact engineering. Yet, usually, a compromise must be made between conductivity and transparency, limiting the

Formation of an Al‐Rich Niccolite‐Type Silica in Subducted Oceanic Crust: Implications for Water Transport to the Deep Lower Mantle

Geophysical Research Letters, 2022
Subducted oceanic crust is enriched in free silica. Although being one of the silica polymorphs at lower‐mantle pressures, niccolite‐type phase (Nt‐phase) has not been documented in multicomponent metabasaltic or metasediment compositions relevant to ...

Band gap closure, incommensurability and molecular dissociation of dense chlorine

Nature Communications, 2019
Molecular systems are predicted to transform into atomic solids and be metallic at high pressure; this was observed for the diatomic elements iodine and bromine. Here the authors access the higher pressures needed to observe the dissociation in chlorine,

Author Correction: Band gap closure, incommensurability and molecular dissociation of dense chlorine

Nature Communications, 2019
The original version of this Article omitted references to previous experimental reports on solid hydrogen that are relevant for a full understanding of the context of the previous work. The added references are: 47. Akahama, Y. et al.

Structural transitions of 4:1 methanol–ethanol mixture and silicone oil under high pressure

Matter and Radiation at Extremes, 2021
A 4:1 (volume ratio) methanol–ethanol (ME) mixture and silicone oil are two of the most widely used liquid pressure-transmitting media (PTM) in high-pressure studies.

Monitoring Of The Center Of Pressure In Unipedal Support In Karate

المجلة العلمية العلوم والتكنولوجية للنشاطات البدنية والرياضية, 2021
Stabilometry is a technique for analyzing posture based on recording the oscillations of a subject's center of pressure (COP) on an instrumented platform. Under unusual or destabilizing conditions, maintaining postural activity requires the establishment of rapid motor reactions.

Toughening of silicon nitride ceramics through stress-induced phase transformation

Journal of Advanced Ceramics
Ceramics, particularly covalently bonded ceramics, exhibit intrinsic brittleness resulting from the strong directional nature of their chemical bonds, significantly limiting their applications.

In situ high-pressure spectroscopic studies using moissanite (4H-SiC) anvils

AIP Advances, 2018
We examined the Raman scattering and IR absorption spectroscopy of 4H-SiC and its performance as an anvil material for high-pressure UV-visible absorption spectroscopic measurements.
