Potential Replacement of the US Navy\u27s Rapid Penetration Test with the Method of Multichannel Analysis of Surface Waves [PDF]

, 2018
The United States Navy (USN) currently utilizes a Rapid Penetration Test (RPT) on both land and in water as the means to determine whether sufficient soil bearing capacity exists for piles in axial compression, prior to construction of the Elevated ...

Clinical Utility of Tissue Proximity Indication With a Variable‐Loop Circular Catheter for Pulmonary Vein Isolation

Journal of Cardiovascular Electrophysiology, EarlyView.
ABSTRACT Background The variable‐loop circular catheter (VLCC, VARIPULSE) is a pulsed‐field ablation (PFA) catheter equipped with a Tissue Proximity Indication (TPI) function, which monitors catheter‐tissue contact. Although TPI‐negative sites have been reported to contribute to gap formation, no studies have evaluated the utility of real‐time function.

Wavefield Analysis of Rayleigh Waves for Near-Surface Shear-Wave Velocity [PDF]

, 2011
Shear (S)-wave velocity is a key property of near-surface materials and is the fundamental parameter for many environmental and engineering geophysical studies. Directly acquiring accurate S-wave velocities from a seismic shot gather is usually difficult

Refined Division of Sleep Stages in the Mouse Based on Distributed Deep Electrodes and Underlying Infra‐Slow Oscillation

Journal of Sleep Research, EarlyView.
ABSTRACT The mouse sleep is mostly recorded with only epidural electrodes and divided simply into NREM and REM stages. With the help of distributed intracerebral triplet electrodes, we searched for possible new electrophysiological signatures to characterise more specific sleep substages within the timeframe of seconds to tens of minutes.

Assessment of different agricultural soil compaction levels using shallow seismic geophysical methods

Geoderma
A well-developed soil structure is crucial for a fertile soil and rules its influence on the ecosystem. Slight variations in the way soil components are organized and connected can greatly impact the soil mechanical and hydraulic characteristics. However,

Determining properties of human‐induced pluripotent stem cell‐derived cardiomyocytes using spatially resolved electromechanical metrics

The Journal of Physiology, EarlyView.
Abstract figure legend In this study, we use human‐induced pluripotent stem cell‐derived cardiomyocyte (hiPSC‐CM) experiments and computational modelling to identify the mechanism of action of drug compounds. In the hiPSC‐CM experiments, optical measurements of cell collections are recorded in the baseline case and after drug exposure.
