Optimization problem for extremals of the trace inequality in domains with holes
We study the Sobolev trace constant for functions defined in a bounded domain
\O that vanish in the subset We find a formula for the first variation
of the Sobolev trace with respect to hole. As a consequence of this formula, we
prove that when \O is a centered ball, the symmetric hole is critical when we
consider deformation that preserve volume but is not optimal for some case.Comment: 13 page
Indirect lattice evidence for the Refined Gribov-Zwanziger formalism and the gluon condensate in the Landau gauge
We consider the gluon propagator at various lattice sizes and
spacings in the case of pure SU(3) Yang-Mills gauge theories using the Landau
gauge fixing. We discuss a class of fits in the infrared region in order to
(in)validate the tree level analytical prediction in terms of the (Refined)
Gribov-Zwanziger framework. It turns out that an important role is played by
the presence of the widely studied dimension two gluon condensate
. Including this effect allows to obtain an acceptable fit up to
1 \'{a} 1.5 GeV, while corroborating the Refined Gribov-Zwanziger prediction
for the gluon propagator. We also discuss the infinite volume extrapolation,
leading to the estimate . As a byproduct, we can
also provide the prediction obtained at
the renormalization scale .Comment: 17 pages, 10 figures, updated version, accepted for publication in

On the motion of a heavy rigid body in an ideal fluid with circulation
Chaplygin's equations describing the planar motion of a rigid body in an
unbounded volume of an ideal fluid involved in a circular flow around the body
are considered. Hamiltonian structures, new integrable cases, and partial
solutions are revealed, and their stability is examined. The problems of
non-integrability of the equations of motion because of a chaotic behavior of
the system are discussed.Comment: 25 pages, 4 figure
MODELS OF FINANCIAL AND ECONOMIC ORGANIZATION AND MEDICO-ECONOMIC EFFICIENCY OF THE ORTHOTICS DEPARTMENT IN A HOSPITAL
This publication shows the relationship of one of the three proposed financial and economic models of orthotics offices, assisting patients with different pathologies of the musculoskeletal system, depending on the category of the hospital. The models of orthotics offices subjected to the analysis differ by a financing source; the system of an assessment of the dominating and minor indicators of their functioning is developed. Possible economic efficiency of the work of this office, working in the compulsory health insurance system is shown in the group of patients (n = 30) with a fracture of the distal end of the radius, and has made more than 377 000,0 rubles per year (according to 2014)
Analysis of social efficiency of the orthotics department in municipal hospital
In this article we analyzed social efficiency of orthotics department at the Central Municipal Hospital of Ulyanovsk. The study was conducted in the period of 2013-2014 years in patients with different diseases. All respondents of experimental (n = 150) and control (n2 = 150) groups who participated in the study expressed positively about the purpose and use of orthoses - "good" (nt = 63,7 %; n2 = 80,7 %) or "no answer" (nt = 36,3 %; n2 = 19,3 %). It shows a high level of social efficiency of provided type of care. Work of orthotics department will increase the number of orthotic devices used to improve the quality of life of patients
Revenue decentralization, central oversight and the political budget cycle : evidence from Israel
This paper examines whether revenue decentralization and direct external
financial supervision affect the incidence and strength of political budget
cycles, using a panel of Israeli municipalities during the period 1999-2009.
We find that high dependence on central government transfers—as
reflected in a low share of locally raised revenues in the municipality’s
budget—exacerbates political budget cycles, while tight
monitoring—exercised through central government appointment of
external accountants to debt accumulating municipalities—eliminates
them. These results suggest that political budget cycles can result from
fiscal institutions that create soft budget constraints: that is, where
incumbents and rational voters can expect that the costs of pre-election
expansions will be partly covered later by the central government
