Atomic squeezing is studied for the case of large systems of radiating atoms, when collective effects are well developed. All temporal stages are analyzed, starting with the quantum stage of spontaneous emission, passing through the coherent stage of superradiant emission, and going to the relaxation stage ending with stationary solutions. A method of governing the temporal behaviour of the squ...

In this paper we present a linear-time and linear-space algorithm for the decomposition of binary images into rectangles. Our contribution is a two-stage algorithm. In the first stage we compute a 1 min(h,w) -approximation for the largest rectangle starting at each point of the matrix. In the second stage the algorithm walks through the matrix, alternatively stacking, merging or removing encoun...

The significant penetration rate of wind turbines in power systems made some challenges in the operation of the systems such as large-scale power fluctuations induced by wind farms. Gas-fired plants with fast starting ability and high ramping can better handle natural uncertainties of wind power compared to other traditional plants. Therefore, the integration of electrical and natural gas syste...

context appropriate management of neonates, tested positive for congenital hypothyroidism (ch), in particular, the initial dosage of levothyroxine and the time of initiation of treatment is a critical issue. the aim of this study was to assess all current evidence available on the subject to ascertain the optimal initial dose and optimal initiation time of treatment for children with ch. eviden...

Epistemic justification has been claimed to be a special case of argument by philosophers such as Accordingly for each attempt, epistemic justification is the occasion of the arguer making a case for some conclusion based on other premises, when the audience and the arguer are the same person. The dialectical model of argument is used to inform how it is that a subject could come to justify her...

This note adds three annexes to my previous paper math/9904044 Annex 1. A sufficient condition for self-adjointness Annex 2. Invariant closed operators on locally compact abelian groups Annex 3. The trace of Connes for quaternions This last item is a minor variation on the evaluation of Connes’s trace (math/9811068), which is explained here in the setting of quaternions and can be applied also ...

Over the past few years electrochemical capacitors (ECs) or, as they are so often referred to today, superor ultracapacitors, have become increasingly interesting for a certain critical group of applications because of their unique attributes. The first of these EC attributes is exceptional power performance, even at very low temperatures. The second is an essentially unlimited cycle life when ...
