Abstract: We consider an Ornstein-Uhlenbeck process with values in Rn driven by a Lévy process (Zt) taking values in R d with d possibly smaller than n. The Lévy noise can have a degenerate or even vanishing Gaussian component. Under a controllability rank condition and a mild assumption on the Lévy measure of (Zt), we prove that the law of the Ornstein-Uhlenbeck process at any time t > 0 has a...

BACKGROUND There are thirteen WHO collaborating centres in Iran which no mechanism or model has ever been foreseen for the evaluation of them. This original research is innovative in Iran, which has been offered by the researcher through a joint research project with WHO. METHODS The aforesaid model has been approved by the International Relation Department of Ministry of Health& education. T...

Color confinement by the mechanism of Kugo and Ojima can treat confinement of any quantized color carrying fields including dynamical quarks. However, the non-perturbative condition for this confinement has been known to be satisfied only in the pure-gauge model (PGM), which is a topological model without physical degrees of freedom. Here we analyze the Yang-Mills theory by adding physical degr...

This is a historical-social description study supported on the thought of Pierre Bourdieu based on documental analysis. It describes the sanitarists and psychiatrists' actions from the reformulation of Education and Public Health Ministry into Education and Health Ministry in the beginning of New State and analyse the fight's strategies of the main agents to take advantage on their proposals of...

We construct a system of bosonic closed string field theory coupled to a Dbrane. The interaction between the D-brane and closed string field is introduced using the boundary state which is a function of constant field strength Fμν and the tilt θ μ of the D-brane. We find that the gauge invariance requirement on the system determines the (Fμν , θ i μ)-dependence of the normalization factor of th...

We investigate quantum deformation of conformal algebras by constructing the quantum space for slq(4, C). The differential calculus on the quantum space and the action of the quantum generators are studied. We derive deformed su(4) and su(2, 2) algebras from the deformed sl(4) algebra using the quantum 4-spinor and its conjugate spinor. The 6-vector in soq(4, 2) is constructed as a tensor produ...

Background There is a global crisis constituting severe shortages of health professionals and mal-distribution of health human resources. There are some important mega trends that affect this challenge: • Populations are aging and becoming more urbanized. • Non-communicable diseases, nutrition-related, and maternity-related causes of death, mental health disorders and chronic diseases are growi...

Uprating of existing Overhead Lines is one approach to increase their capacity. APG is considering uprating certain 220 kV-lines to 380 kV in the near future. To this end new technical components have been developed. However requirements for an uprating are not exclusively technical, standards and legal aspects, environmental impacts as well as economical considerations have to be investigated ...
