Quasi-coherent micro-instabilities is one of the key topics of magnetic confinement fusion. this work focuses on the quasi-coherent spectra of ion temperature gradient(ItG) and trapped-electron-mode instabilities using newly developed far-forward collective scattering measurements within ohmic plasmas in the J-tEXt *** ItG mode is characterized by frequencies ranging from 30 to 100 k Hz and wavenumbers(k_(θρs)) less than 0.3. Beyond a critical plasma density threshold, the ItG mode undergoes a bifurcation, which is marked by a reduction in frequency and an enhancement in amplitude. Concurrently, enhancements in ion energy loss and degradation in confinement are observed. this ground-breaking discovery represents the first instance of direct experimental evidence that establishes a clear link between ItG instability and ion thermal transport.

Coronary Artery Vasospasm with Acute Myocardial Infarction in a Male Patient： Case Report

We present a 48-year-old male patient with a history of classic precordialgia, St-segment elevation in inferior leads （II, III and aVF）, with t：oponin m：d CK-MB （creatine kinase-MB） elevated on the day of admission that received conventional anti-ischemic treatment. Hemodynamically stable, symptom-free, is referred to cardiac catheterization. In the selective catheterization of the left coronary artery, a moderate lesion was observed in the middle third of the anterior descending coronary artery; in the right coronary artery, a subocclusive proximal lesion with tIMI （thrombolysis in myocardial infarction） II. We performed a single projection m：d opted for angioplasty. Before, it was decided to re-evaluate the left coronary artery, m：d it was observed in the contrast test that anterior descending artery was occluded. Intra-coronary nitroglycerin and new contrast injection were performed, which showed totally open descending artery with tIMI III, without obstructive lesions as initially suggested, and improvement of pain. It was a severe coronary vasospasm. When a new contrast injection was performed in the right coronary, with a therapeutic catheter, the disappeaxance of the subocclusive lesion and the presence of a normal coronary flow were observed, although there was a moderate plaque in its proximal third, which motivated the maintenance of angioplasty with stent placement in a proxhnal third of right coronary artery. During the passage of the intracoronary guidewire it was once again evident that diffuse coronary artery vasoreactivity was present; the procedure was successfully completed.

Recently,I was standing in the corridor of a middle school,and I heard the following ex-change between a student and a teacher who,like so many teachers these days,was hurrying,ina harassed sort of way,from one classroom to another,her arms filled with exercise books andother educational paraphernalia."Excuse me,Miss!"said the student."I don’t quite understand the third conditional!""Good question!"replied the teacher."Why don’t you look it up in the grammar notes at theback of the book?"Saying which,she swept off to her next *** question arises:was this teacher a good teacher,or a bad teacher?I hope that we shall inthe course of the next hour or so seek to establish an answer to this question!
