Finsler Metrics with Bounded Cartan Torsions
The norm of Cartan torsion plays an important role for studying of immersion
theory in Finsler geometry. Indeed, Finsler manifold with unbounded Cartan
torsion can not be isometrically imbedded into any Minkowski space. In this
paper, we find two subclasses of (?, ?)-metrics which have bounded Cartan
torsion. Then, we give two subclasses of (?, ?)-metrics whose bound on the
Cartan torsions are independent of the norm of ?

The orbit method solution for the deformed three coupled scalar fields
In this work, we present a deformed solutions starting from systems of three
coupled scalar fields with super-potential by orbit
method. First, we deform the corresponding super-potential and obtain defect
solutions. It is shown that how to construct new models altogether with its
defect solutions in terms of the non-deformed model. Therefore, we draw the
graph of super-potential and different fields in terms of So we observe
that the graphs for deformed and non - deformed cases are changed by the scale.Comment: 9 pages, 5 figure
Baryon Binding Energy in Sakai-Sugimoto Model
The binding energy of baryon has been studied in the dual
string theory with a black hole interior. In this picture baryon is constructed
of a brane vertex wrapping on and fundamental strings
connected to it. Here, we calculate the baryon binding energy in Sakai-Sugimoto
model with a in which the supersymmetry is completely
broken. Also we check the dependence of the baryon binding energy. We
believe that this model represents an accurate description of baryons due to
the existence of Chern-Simones coupling with the gauge field on the brane. We
obtain an analytical expression for the baryon binding energy . In that case we
plot the baryon binding energy in terms of radial coordinate. Then by using the
binding energy diagram, we determine the stability range for baryon
configuration. And also the position and energy of the stable equilibrium point
is obtained by the corresponding diagram. Also we plot the baryon binding
energy in terms of temperature and estimate a critical temperature in which the
baryon would be dissociated.Comment: 14 pages, 1 fi
Decay widths of large-spin mesons from the non-critical string/gauge duality
In this paper, we use the non-critical string/gauge duality to calculate the
decay widths of large-spin mesons. Since it is believed that the string theory
of QCD is not a ten dimensional theory, we expect that the non-critical
versions of ten dimensional black hole backgrounds lead to better results than
the critical ones. For this purpose we concentrate on the confining theories
and consider two different six dimensional black hole backgrounds. We choose
the near extremal AdS6 model and the near extremal KM model to compute the
decay widths of large-spin mesons. Then, we present our results from these two
non-critical backgrounds and compare them together with those from the critical
models and experimental data.Comment: 21 pages and 3 figure
The main transition in the Pink membrane model: finite-size scaling and the influence of surface roughness
We consider the main transition in single-component membranes using computer
simulations of the Pink model [D. Pink {\it et al.}, Biochemistry {\bf 19}, 349
(1980)]. We first show that the accepted parameters of the Pink model yield a
main transition temperature that is systematically below experimental values.
This resolves an issue that was first pointed out by Corvera and co-workers
[Phys. Rev. E {\bf 47}, 696 (1993)]. In order to yield the correct transition
temperature, the strength of the van der Waals coupling in the Pink model must
be increased; by using finite-size scaling, a set of optimal values is
proposed. We also provide finite-size scaling evidence that the Pink model
belongs to the universality class of the two-dimensional Ising model. This
finding holds irrespective of the number of conformational states. Finally, we
address the main transition in the presence of quenched disorder, which may
arise in situations where the membrane is deposited on a rough support. In this
case, we observe a stable multi-domain structure of gel and fluid domains, and
the absence of a sharp transition in the thermodynamic limit.Comment: submitted to PR
Thermodynamics of string black hole with hyperscaling violation
In this paper, we start with black brane and construct specific space-time
which violates hyperscaling. In order to obtain the string solution we apply
Null-Melvin-Twist and -reduction. By using the difference action method we
study thermodynamics of system to obtain Hawking-Page phase transition. In
order to have hyperscaling violation we need to consider
In that case the free energy is always negative and our solution is thermal
radiation without a black hole. Therefore we find that there is not any
Hawking-Page transition. Also, we discuss the stability of system and all
thermodynamical quantities.Comment: 12 pages. Accepted for publication in EPJ
Asymptomatic bacteriuria and pyuria in patients with chronic renal failure undergoing hemodialysis at dialysis centers in Kermanshah, Iran
Pyuria is the presence of increased numbers of polymorphonuclear leukocytes in the urine and is evidence of an inflammatory response in the Urinary Tract Infection (UTI). The aim of this study is determination asymptomatic bacteriuria and pyuria in patients undergoing hemodialysis with chronic renal failure. Out of 103 patients with renal failure undergoing hemodialysis who were able to produce urine with clean catch way, we received urine sample. All samples were examined by the Microbiologist in Central Laboratory of Kermanshah, Iran. The mean age for the patients at diagnosis was 42.4 years (range, 20-67 years). Sixty-four patients (62.5) were male and thirty-nine (37.5) were female. Results have been showed 39 cases were aged between 44-49 years and the highest number cases were middle-aged. Out of 31 patients with leukocytosis, 14 patients had age between 44-49 years and majority of them were male. Pyuria(>10 WBC/HPF or 10 WBC/HPF) developed colony count more than 105 colony-forming units per milliliter that indicating positive culture. Microorganisms didn�t grow in patients (10/19) with pyuria (10 WBC/HPF is a good marker for significant bacteriuria in these patients. © 2015 Academic Journals Inc
