When I was a student at university, my major field of study was Electrical Engineering. I did not specialize in chemistry in my studies at university, and my knowledge of chemistry overall was somewhat less than rich. Under those circumstances, upon entering the company, I applied myself wholeheartedly to the study of chemistry to challenge and overcome a barrier in analytical chemistry conside...

A quantum network is constructed of straight quantum wiresthe leads, of constant width,and quantum wells, which play roles of the vertex domains of the network. Basic element of the network is the junction: a detail of the network consisting of a single compact quantum well and few semi-infinite wires attached to it. In the theoretical study of the one-body transport on a junction, the role of ...

We consider a one-body spin-less electron spectral problem for a resonance scattering system constructed of a quantum well weakly connected to a noncompact exterior reservoir, where the electron is free. The simplest kind of the resonance scattering system is a quantum network, with the reservoir composed of few disjoint cylindrical quantum wires, and the Schrödinger equation on the network, wi...

Industrial embedded real-time systems such as cabin communication systems (CCS) of modern (passenger) aircrafts [20], are highly complex. Verification of such complex systems is either hampered by the state space explosion problem, –attached to state-based verification,– or lacks a high-degree of detail, –due to the usage of some analytic method. For achieving a detailed analysis of system comp...

Abstract: Completing the results achieved in a previous paper, we prove the symmetry of Hadamard/Seeley-deWitt off-diagonal coefficients in smooth D-dimensional Lorentzian manifolds. To this end, it is shown that, in any Lorentzian manifold, a sort of “local Wick rotation” of the metric can be performed provided the metric is a locally analytic function of the coordinates and the coordinates ar...

Circulating microRNAs are robustly present in plasma or serum and have become a research focus as biomarkers for tumor diagnosis and prognosis. Centrifugation is a necessary procedure for obtaining high-quality blood supernatant. Herein, we investigated one-step and two-step centrifugations, two centrifugal methods routinely used in microRNA study, to explore their effects on plasma microRNA qu...

BACKGROUND Thoracic endovascular aortic repair is characterized by a substantial need for reintervention. Secondary open aortic procedure becomes necessary when further endoluminal options are exhausted. This synopsis and quantitative analysis of available evidence aims to overcome the limitations of institutional cohort reports on secondary open aortic procedure. METHODS AND RESULTS Electron...

There are a number of technical and statistical problems in monitoring the temporal and spatial variation of local area death rates in the United States for evidence of systematically elevated risks. An analytic strategy is proposed to reduce one of the major statistical concerns, i.e., that of identifying areas with truly elevated mortality risks from a large number of local area comparisons. ...

Selection of qualified persons suitable for different organization functions is a key success factor for an organization. The complexity and importance of the problem call for analytical methods rather than intuitive decisions. The personnel selection problem requires the application of multi-criteria decision making (MCDM) methods for robust recruitment. This paper has to objectives; first to ...
