We investigate the free energy and entropy of Gaussian massive scalar field theory in static de Sitter space-time for arbitrary temperature. For inverse temperatures form $\ensuremath{\beta}=2\ensuremath{\pi}{2}^{k}$, $k\ensuremath{\in}\mathbf{Z}$, curvature units, we find explicit its derivatives with respect to There are two types contributions energy: one is ``area type'' can be attributed h...

This paper deals with the study of global analysis following $(1,2)-$type system non-linear difference equations:\[ u_{n+1}=\frac{\alpha v_{n-1}}{\beta +\gamma v_{n}^{p}v_{n-2}^{q}},\ \ v_{n+1}=\frac{\alpha _{1}u_{n-1}}{\beta _{1}+\gamma _{1}u_{n}^{p}u_{n-2}^{q}},\ n=0,1,... \] where parameters $\alpha ,\beta ,\gamma ,\alpha _{1},\beta _{1},\gamma _{1,}p,q$ and initial conditions $u_{i},v_{i},$...

background: hb a2 is elevated in subjects with beta thalassemia minor but small percent of carriers have normal hb a2 with elevated levels of hbf (2-10%). this type of thalassemia is called delta beta thalassemia, and can be missed in pre-marriage hematologic consults or screening which leads to increased risk of child birth with beta thalassemia major. materials and methods: in this prospectiv...

Beta-2 microglobulin is a sensitive surrogate test for HIV infection for use in jurisdictions where HIV antibody tests are not allowed to be performed on life insurance applicants by law/regulation. The advantage of beta-2 microglobulin over T cell testing, which is a surrogate test also used by the life insurance industry for detecting HIV infection, is the stability of B 2M in serum over lon...

We investigate the localization transition for a simple model of interface which interacts with an inhomonegeous defect plane. The is modeled by graph function $\phi: \mathbb Z^2 \to Z$,and disorder given fixed realization field IID centered random variables$(\omega_x)_{x\in Z^2}$. Hamiltonian system depends on three parameters $\alpha,\beta>0$ and $h\in R$ determine respectively intensity near...

let $gamma_{n,kappa}$ be the class of all graphs with $ngeq3$ vertices and $kappageq2$ vertex connectivity. denote by $upsilon_{n,beta}$ the family of all connected graphs with $ngeq4$ vertices and matching number $beta$ where $2leqbetaleqlfloorfrac{n}{2}rfloor$. in the classes of graphs $gamma_{n,kappa}$ and $upsilon_{n,beta}$, the elements having maximum augmented zagreb index are determined.
