Bow shock in merging cluster A520: the edge of the radio halo and the electron-ion equilibration timescale [PDF]
2018, ApJ, 856, 162, 2018 We studied the prominent bow shock in the merging galaxy cluster A520 using a deep Chandra X-ray observation and archival VLA radio data. This shock is a useful diagnostic tool, owing to its clear geometry and relatively high Mach number. At the "nose" of the shock, we measure a Mach number of $M=2.4_{-0.2}^{+0.4}$.

Advancements and Prospects of Electronic Nose in Various Applications: A Comprehensive Review
Applied SciencesAn electronic nose, designed to replicate human olfaction, captures distinctive ‘fingerprint’ data from mixed gases or odors. Comprising a gas sensing system and an information processing unit, electronic noses have evolved significantly since their ...

Online Decorrelation of Humidity and Temperature in Chemical Sensors for Continuous Monitoring [PDF]
Chemometrics and Intelligent Laboratory Systems, v 157, p 169-176,
2016, 2016 A method for online decorrelation of chemical sensor signals from the effects of environmental humidity and temperature variations is proposed. The goal is to improve the accuracy of electronic nose measurements for continuous monitoring by processing data from simultaneous readings of environmental humidity and temperature.

Plasma physical parameters along Coronal Mass Ejection-driven shocks: I observations [PDF]
, 2014 In this work UV and white light (WL) coronagraphic data are combined to derive the full set of plasma physical parameters along the front of a shock driven by a Coronal Mass Ejection. Pre-shock plasma density, shock compression ratio, speed and inclination angle are estimated from WL data, while pre-shock plasma temperature and outflow velocity are ...

Freshness Evaluation of Three Kinds of Meats Based on the Electronic Nose
Sensors, 2019 The aim of this study was to use an electronic nose set up in our lab to detect and predict the freshness of pork, beef and mutton. Three kinds of freshness, including fresh, sub-fresh and putrid, was established by human sensory evaluation and was used ...

Forward modelling to determine the observational signatures of white-light imaging and interplanetary scintillation for the propagation of an interplanetary shock in the ecliptic plane [PDF]
Journal of Atmospheric and Solar-Terrestrial Physics, 73(2011),
1270-1280, 2010 Recent coordinated observations of interplanetary scintillation (IPS) and stereoscopic heliospheric imagers (HIs) are significant to continuously track the propagation and evolution of solar eruptions throughout interplanetary space. In order to obtain a better understanding of the observational signatures in these two remote-sensing techniques, the ...
