Ultrasonically actuated microbubble oscillations hold great promise for minimally invasive therapeutic interventions. However their successful translation to the clinic, real-time methods control amplitude and type of micro-bubble (stable versus inertial acoustic cavitation) ensure that cavitation occurs within targeted region are needed. In this paper, we propose a nonlinear state controller uses specific frequency bands emissions (harmonic, ultra-harmonic, etc.) activity (observer states)....
Solar X-ray Monitor (XSM) is one of the scientific instruments onboard Chandrayaan-2 orbiter.The XSM along with instrument CLASS (Chandra's Large Area soft Spectrometer) comprise remote fluorescence spectroscopy experiment mission an objective to determine elemental composition lunar surface on a global scale.XSM will measure solar X-rays in energy range 1-15 keV using state-of-the-art silicon drift detector.The flight model payload has been designed, realized and characterized for various...
Solar flares, with energies ranging over several orders of magnitude, result from impulsive release energy due to magnetic reconnection in the corona. Barring a handful, almost all microflares observed X-rays are associated solar active regions. Here we present, for first time, comprehensive analysis large sample quiet Sun soft by X-ray Monitor (XSM) on board Chandrayaan-2 mission during 2019-20 minimum. A total 98 having peak flux below GOES A-level were XSM observations spanning 76 days....
Elements with low First Ionization Potential (FIP) are known to be three four times more abundant in active region loops of the solar corona than photosphere. There have been observations suggesting that this observed "FIP bias" may different other parts and such thus important understanding underlying mechanism. The Solar X-ray Monitor (XSM) on board Chandrayaan-2 mission carried out spectroscopic Sun soft X-rays during 2019-20 minimum, considered quietest minimum past century. These...
We use a custom-made calibrator to measure individual detectors' polarization angles of BICEP3, small aperture telescope observing the cosmic microwave background (CMB) at 95GHz from South Pole. describe our calibration strategy and statistical systematic uncertainties associated with measurement. reach an unprecedented precision for such measurement on CMB experiment, repeatability each detector pair $0.02\deg$. show that relative measured using this method are in excellent agreement those...

Aditya Solar wind Particle EXperiment (ASPEX) one three in-situ science experiments on-board Aditya-L1 that provides measurements primarily protons alphas wind, suprathermal, energetic particles energy range from 100 eV to 6 MeV/nucleon. ASPEX consists two independent spectrometers:...
<title>Abstract</title> On-board India’s Aditya L1 spacecraft is the Solar Wind Ion Spectrometer (SWIS) instrument which a part of Particle Experiment (ASPEX), one three instruments carrying out in-situ measurements solar wind. SWIS, comprising two Top Hat Analyzers (THA-1 andTHA-2), designed to measure flux, energy distribution and angular primarily proton (H+ ions) alpha (He2+ particles in range 0.1–20 keV with 360◦ coverage planes, ecliptic plane perpendicular it.
