Considering a temperature dependent two-level quantum system, we have numerically solved the Landau-Zener transition problem. The method includes the incorporation of temperature effect as a thermal noise added Schrödinger equation for the construction of the Hamiltonian. Here, the obtained results which describe the changes in the system including the quantum states and the transition pro...

Classical game theory assumes that agents always choose optimal strategies and assume that other agents in the game also do so. However, a good deal of experimental evidence (as well as common sense) suggests that people are not so perfectly rational and only learn by experience to choose optimal strategies, if they do so at all. 1 Much evidence from experimental game theory is consistent with ...

We consider a class of Markov chains modelling concurrent activities with phase-type (PH) distributed duration. Specifically we focus on systems whose dynamics is characterised by the parallel execution of a number of active jobs and such that the termination of an active job causes the remaining active jobs to be restarted from scratch (preemptive restart policy) or deactivated and can lead to...

Quantum computing (QC), by exploiting the quantum properties of bits (qubits), significantly improves performance and efficiency computation. Unfortunately, devices are very susceptible to external perturbation, including natural radiation. In this article, we measure, through GEANT4 simulations, charge deposited impinging neutrons in superconducting devices. As show, most atmospheric deposit s...

our aim was to report techniques and our experience in one-stage angioplasty and stenting of ostium of left common carotid and left internal carotid arteries in an octogenarian man with transient ischemic attack, who was completely recovered from neurologic insults short time after the procedure. an 81-year-old man presented with a transient ischemic attack. neurologic examination showed left s...

background primary congenital hypothyroidism (ch) is the most common treatable cause of mental retardation and can be classified into permanent and transient types. the purpose of this study was to determine the prevalence of permanent and transient congenital hypothyroidism (ch) in hamadan, west province of iran. methods the study population included all cases with primary congenital hypothyro...

background: transient and stable transformation of host plants are the common techniques to produce transgenic plants. however, the main drawback of stable transformation is the fact that it takes quite a long time to produce a transgenic line. while, transient gene expression is a quick method to produce recombinant proteins in plants.  objective: the main goal of the present study was to eval...

cerebrovascular attack (cva) and transient ischemic attack (tia) are major causes of emergency department visits around the globe. a significant number of these patients may experience repeat attacks if left untreated. several risk stratifying scoring systems have been developed in recent years to point out the high risk patients. abcd 2 is based on age, blood pressure, clinical status, diabete...

one of the most preventable causes of mental and growth retardation is congenital hypothyroidism (ch). this study tries to investigate growth and mental outcome of patients with ch. since november 2006 and november 2007 in guilan province, north of iran, all neonates who were diagnosed with ch, evaluated for etiology of ch by laboratory follow up, thyroid sonography or scan. growth and developm...
