Objective: Coronary heart disease (CHD) is one of the most common diseases. Coronary angiography (CAG) is an important apparatus used to diagnose and treat this disease. Since angiography is performed through exposure to ionizing radiation, it can cause harmful effects induced by double-stranded breaks in DNA which is potentially life-threatening damage. The aim of the present study is to inves...

We investigate analytically the effect of an anisotropic distribution of the kinetic energy within a relativistic fireball on the decay of the afterglow emission, focusing on axially symmetric fireballs with a uniform core and a power-law decrease with angle outside the core. The afterglow fall-off steepens after the core becomes fully visible. For observer directions within the core, simple fo...

objective: in this paper, we have introduced topoisomerase inhibitors, mechanism of action and types of them. dna topoisomerases are ubiquitous enzymes that catalyze essential enzymes to solve the topological problems accompanying key nuclear processes such as dna replication, transcription, repair and chromatin assembly by introducing temporary single or double strand breaks in the dna. result...

A set is an unordered (unless otherwise specified) collection of elements of the same type, usually expressed using the following notation: {elem1, elem2, elem3, . . .} A tuple is an ordered collection of elements, not necessarily of the same type, expressed using the following notation: (elem1, elem2, elem3, . . .) Most of the times, we don’t give too much attention to the actual elements them...

The simplest interpretation of the global success of the Standard Model is that new physics decouples well above the electroweak scale. Supersymmetric extension of the Standard Model offers the possibility of light chargino and the right-handed stop (with masses below MZ), and still maintaining the successful predictions of the Standard Model. The value of Rb can then be enhanced up to ∼ 0.218 ...

We used quantitative genetics techniques to compare the entrepreneurial activity of 870 pairs of monozygotic (MZ) and 857 pairs of same-sex dizygotic (DZ) twins from the United Kingdom. We ran model-fitting analyses to estimate the genetic, shared environmental and nonshared environmental effects on the propensity of people to become entrepreneurs. We found relatively high heritabilities for en...

Magnetic Weyl semimetals (MWSMs) have attracted significant attention due to their intriguing physical properties and potential applications in spin-electronic devices. Here we report the characterization of NdAlSi including transport, magnetization, heat capacity on single crystals, as well band structure calculation. It is a newly proposed MWSM candidate which breaks both time-reversal spatia...
