A nuclear power plant is a complex coupling system, which features multi-physics between reactor physics and thermal-hydraulics in the core, as well multi-circuit primary circuit secondary by shared steam generator (SG). Especially pebble-bed modular HTR plant, different supply modules are further coupled together through main pipes related equipment circuit, since special configuration of mult...

Astigmatism’s defect has not yet been formulated in Physics and medical physics books theoretically. In this paper, we are trying to formulate the astigmatism’s defect. The results of formulation show that “the degree of astigmatism is negative reverse the distance that vision’s condition of astigmatism’s chart lines change conditions in dimness angle from dimness condition at infinite distance...

I review models for the "inner jet" in blazars, the section that connects the central engine with the radio jet. I discuss how the structure and physics of the inner jet can be explored using millimeter-wave VLBI (very-long-baseline radio interferometry) as well as multiwaveband observations of blazars. Flares at radio to gamma-ray frequencies should exhibit time delays at different wavebands t...

In fields as diverse as sociology and physics researchers have been investigating the rich networks that exist in nature. More recently, a small number of multi-agent researchers have shown that the performance of a group can be significantly impacted by the nature of the network that connects them. In this chapter, we build on these initial efforts, performing systematic experiments in an atte...

1. INTRODUCTION Progress in science is critically dependent on advances of its instruments. Accelerators are one of the principal instruments of high energy physics, and particle physics discoveries are often preceded by accelerator developments. Examples are the discovery of the T and one of the two independent discoveries of the J/v that followed the construction of SPEAR, the first modem e+e...

We present a systematic study of the steep decay emission from gamma-ray bursts (GRBs) observed by the Swift X-Ray Telescope (XRT). In contrast to the analysis described in recent literature, we produce composite Burst Alert Telescope (BAT) and XRT light curves by extrapolating the XRT data (2–10 keV) into the BAT energy range (15–25 keV) rather than extrapolating the BAT data into the XRT ener...

Einstein's special theory of relativity revolutionized physics by teaching us that space and time are not separate entities, but join as " spacetime ". His general theory of relativity further taught us that spacetime is not just a stage on which dynamics takes place, but is a participant: The field equation of general relativity connects matter dynamics to the curvature of spacetime. Curvature...

We obtain exact relations (valid to all orders in the coupling constant) for the running gaugino mass in supersymmetric gauge theories, treating the soft supersymmetry breaking effects in the linear approximation. If a supersymmetry breaking squark (selectron) mass term is introduced, our relation connects the renormalization group equation for this term with that for the gaugino mass. Exact re...
