We use the thermodynamic model introduced by Aptekar’ and Ponyatovskiy for the – transformation in cerium metal to study the properties f plutonium metal. The model describes the – transformation in Pu and explains the minimum in the melting versus pressure curves for both aterials. Ga stabilization of the -phase of Pu is explained in terms of a first order transition between the two phases. Th...

We propose a massless nonminimally coupled scalar field as a mechanism for stabilizing the size of the extradimension in the Randall-Sundrum I scenario. Without needing to introduce self interactions terms we obtain a potential for the modulus field that sets the size of the fifth dimension. The minumum of this potential yields appropriate values of the compactification scale for small values o...

This paper addresses the stabilization problem for unmanned air vehicles over digital and wireless communication channels with time delay. In particular, the case with band-limited channels is considered. An observer-based state feedback control policy is employed to stabilize the linear control system of unmanned air vehicles. A sufficient condition on the minimum data rate for mean square sta...

This paper deals a continuous-time state-dependent jump linear system, a particular kind of stochastic switching system. In particular, we consider a situation when the transition rate of the random jump process depends on the state variable, and addressed the problem of stochastic stability and stabilization analysis for the proposed system. Numerically solvable sufficient conditions for the s...

Background. The study aims to verify if the time of preoperative stabilization (≤24 or >24 hours) could be predictive for the severity of clinical condition among patients affected by congenital diaphragmatic hernia. Methods. 55 of the 73 patients enrolled in the study achieved presurgical stabilization and underwent surgical correction. Respiratory and hemodynamic indexes, postnatal scores, th...

Giant cell tumor (GCT) involving distal ulna being rare with reported rate of 0.45-3% of all GCT cases; the literature has only sporadic cases reported. Various treatment options have been proposed, and dilemma exist whether to do resection alone or resection combined with stabilization or reconstruction. Also, there is no conclusive evidence regarding the method of stabilization or reconstruct...

After a well starts flowing, a larger and larger portion of the reservoir contributes to production. At any given time, the radius of the portion of the reservoir that demonstrates a pressure gradient and contributes to production of fluid is the radius of drainage (ROD). The time required for the entire reservoir just to be able to contribute production is the stabilization time. Estimating th...
