Nested order-disorder framework containing a crystalline matrix with self-filled amorphous-like innards

Nature Communications, 2022
The synthesis and characterization of new crystalline-amorphous hybrid materials is challenging. Here, the authors report the preparation of a nested order-disorder framework by applying high pressure to a nested copper chalcogenide Cu12Sb4S13.

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.

A Novel Method for Gait Analysis on Center of Pressure Excursion Based on a Pressure-Sensitive Mat

International Journal of Environmental Research and Public Health, 2020
Center of pressure (COP) during gait is a useful measure for assessing gait ability and has been investigated using platform or insole systems. However, these systems have inherent restrictions in repeated measure design or in obtaining true vertical ...

Discovery of the Baijifeng impact structure in Tonghua, Jilin, China

Matter and Radiation at Extremes, 2023
An impact structure 1400 m in diameter, formed by a bolide impact, has been discovered on Baijifeng Mountain in Tonghua City in Northeast China’s Jilin province. The impact structure takes the form of a cirque-shaped depression on the top of the mountain

The effect of ankle osteoarthritis and total ankle arthroplasty on center of pressure position

Journal of Orthopaedic Research, 2020
Total ankle arthroplasty (TAA) is a common surgical approach for patients with end‐stage ankle osteoarthritis (OA). However, very little is known about the path of the center of pressure (COP) of the foot, and thus important aspects of load transfer ...

Circular Components in Center of Pressure Signals

Motor Control, 2013
Static posturography provides an objective assessment of postural control by characterizing the body sway during upright standing. The center of pressure (COP) signal is recorded by a force platform, and it is analyzed by means of many different models and techniques.

A new tonometer based on the application of micro-mechanical sensors [PDF]

, 1993
An instrument for the measurement of intraocular pressure (IOP) is presented. It consists of a micromachined silicon sensor, which measures the diameter of a flattened part of the eye globe and simultaneously determines the smallest distance between the ...

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 ...
