Discrete breathers in square lattices from delocalized nonlinear vibrational modes.

Standing and moving discrete breathers (or equally, intrinsic localized modes) in a square β-Fermi-Pasta-Ulam-Tsingou lattice are obtained by applying localizing functions to the delocalized nonlinear vibrational modes (DNVMs) found earlier by Ryabov and Chechin. The initial conditions used in our study do not correspond to exact spatially localized solutions, but make it possible to obtain long-lived quasibreathers. The approach employed in this work can easily be used to search for quasibreathers in three-dimensional crystal lattices, for which DNVMs with frequencies outside the phonon spectrum are known.

[Clinical efficacy of electric stimulation of crural muscles in comprehensive treatment of post-thrombotic disease].

The purpose of the study was to evaluate clinical efficacy of electromyostimulation (EMS) of the crural muscles as part of comprehensive therapy for post-thrombotic disease in patients with residual venous obstruction in the femoropopliteal segment. We carried out a prospective comparative clinical study enrolling patients having endured a fist episode of clinically unprovoked venous thrombosis of the femoropopliteal segment and completed the standard 6-month course of anticoagulant therapy and presenting with ultrasonographic signs of complete recanalization of the proximal venous segments (stenosis of 20% and more from the vessel's initial diameter), as well as scoring 5 points and more by the Villalta scale. The study included a total of 60 patients (38 men and 22 women, mean age 58.

[Endovascular laser obliteration in treatment of patients with varicose veins with trophic disorders].

The authors studied efficacy and safety of endovasal laser obliteration (EVLO) in treatment for varicose veins in patients with trophic disorders, carrying out comparative analysis of the outcomes of treatment of 95 patients subjected to EVLO (Study Group) or combined phlebectomy (Control Group). It was shown that EVLO is accompanied by less traumatic lesion of tissues during interventions, thus leading to more rapid relief of oedemas of lower limbs and reduction of trophic skin disorders. In patients with open trophic ulcers with an area of more than 10 cm2 healing occurred averagely one month faster than in those after phlebectomy.

[On the state of the budgetary funding of government forensic medical expert institutions in the Russian Federation].

The data on the budgetary funding of state-owned forensic medical bureaus in the Russian Federation for the period from 2005 to 2008 were collected and analysed. The results of the overall estimation and parameters characterizing the level of funding of these expert facilities are presented. Selected state forensic medical bureaus have been ranked based on the level of their financial support.
