We report the experimental observation of ion heating by the mode-converted ion Bernstein waves (MC IBWs) in tokamak plasmas. The MC IBW is created from the fast waves launched from the high-field-side antenna in the HT-7 tokamak in plasmas consisting of deuterium majority, hydrogen minority and 7Li ions. Experimental evidence and numerical simulation show that the interaction between the MC IB...

Ultralight axions and dark photons are well-motivated matter candidates. Inside the plasma, once mass of ultralight candidates equals plasma frequency, they can resonantly convert into electromagnetic waves, due to coupling between particles standard model photons. The converted waves monochromatic. In this article, we review development using radio detectors search for conversions in solar cor...

introduction: opiates cause dependency via affect on central nervous system. locus coeruleus nucleus is a main group of noradrenergic neurons in the brain that plays an important role in the expression of opioid withdrawal signs. during opioid withdrawal, brain waves change in addition to physical and behavioral signs. in this study, we examined the effects of locus coeruleus electrical stimula...

Overburden layers continue to be a problem for recording and analyzing information in seismic surveys. This study aims to examine the effects of overburden layers on seismic wave propagation and imaging. In the investigation, we look at the effect of low velocity, low density overburden on seismic imaging. To investigate this problem, a finite difference elastic wave modelling study was conduct...

IN CONGENITAL dextrocardia the problem is frequently whether dextroversion or a mirror-image dextrocardia is present. In the former the atria preserve their usual relationship in the frontal plane but the left ventricle lies anterior to the right. In mirror-image dextrocardia there is atrial inversion and the right ventricle lies anterior to the left. The electrocardiographic findings are gener...

The power coupled to electron Bernstein waves in a triplet mode conversion resonator from a fast X-mode at the plasma edge in NSTX is shown to be > 80% for fc, < f < 2fc,. The EBW damping in the plasma is strong and localized and, thus, should be useful for heating, current drive, or profile control.
