a simple semi-phenomenological model, which accurately predicts the dependence of thresholdcurrent for temperature of resonant-phonon three well quantum cascade laser based on verticaltransitions is offered. we found that, the longitude optical phonon scattering of thermally excitedelectrons is the most important limiting factor for thermal performance of high frequency thz qcls.in low frequenc...

In most modern manufacturing systems, products are often the output of some multistage processes. In these processes, the stages are dependent on each other, where the output quality of each stage depends also on the output quality of the previous stages. This property is called the cascade property. Although there are many studies in multistage process monitoring, there are fewer works on prof...

The problem of expressing a given nonlinear statespace system as the cascade connection of a lossless system and a stable, minimum-phase system (inner-outer factorization) is solved for the case of a stable system having state-space equations affine in the inputs. The solution is given in terms of the stabilizing solution of a certain Hamilton-Jacobi equation. The stable, minimum-phase factor i...

This paper considers H∞-control of infinitedimensional systems whose transfer functions are expressible as the cascade connection of a rational transfer matrix and a scalar (possibly irrational) inner function. This class of systems is very suitable for describing many control problems in practice, when weighting functions are rational and plants have at most finitely many unstable modes. We sh...

Current knowledge of the immunopathogenesis of psoriasis vulgaris is based on the crucial role of CD4 and CD8 lymphocytes. Also, the connection of activated lymphocytes with macrophages, especially dendritic cells and plasmacytoid dendritic cells, is considered to be significant. In the present study, the expression of CD4+ lymphocytes as well as CD8+ lymphocytes (P < 0.001) and macrophages (P ...

Dynamic neural network algorithms are used for automatic network design in order to avoid time consuming search for finding an appropriate network topology with trial & error methods. The new FlexNet algorithm, unlike other network construction algorithms, does not underlie any constraints regarding the number of hidden layers and hidden units. In addition different connection strategies are av...
