SCARS: MORPHOGENESIS, CLASSIFICATION, DIAGNOSIS AND TREATMENT OF SCARS

High frequency of scar skin pathology, the lack of schemes for highly effective treatment and prevention of scarring, increased demands on the quality of life of patients with scars make this problem urgent. Moreover, despite the increased interest of researchers in the problem of the morphogenesis of pathological scars it is necessary further study of it. Summarized the experience of using different methods of scars treatment with different etiologies and emphasized on combined treatment

Dairy robotic milking system

The article presents the results of studying the technology of robotic milking in the aspect of digitalization of dairy cattle breeding. The relevance of the topic lies in the fact that in Russia the task is to introduce the technology of “precise” animal husbandry based on digital technologies. It is noted that in our country there are successfully functioning dairy complexes, where digital technology tools, including robotics, have been introduced. The technologies for identifying animals, determining the quality of milk, controlling the robotic complex and the milking process are described. The robotic milking system is a progressive technology in terms of the use of digital technology elements: big data, the Internet of things, artificial intelligence. It is necessary to take into account the experience of these farms in order to increase the efficiency of introducing innovations

Search for direct production of charginos and neutralinos in events with three leptons and missing transverse momentum in √s = 7 TeV pp collisions with the ATLAS detector

A search for the direct production of charginos and neutralinos in final states with three electrons or muons and missing transverse momentum is presented. The analysis is based on 4.7 fb−1 of proton–proton collision data delivered by the Large Hadron Collider and recorded with the ATLAS detector. Observations are consistent with Standard Model expectations in three signal regions that are either depleted or enriched in Z-boson decays. Upper limits at 95% confidence level are set in R-parity conserving phenomenological minimal supersymmetric models and in simplified models, significantly extending previous results

Measurement of D*+/- meson production in jets from pp collisions at sqrt(s) = 7 TeV with the ATLAS detector

This paper reports a measurement of D*+/- meson production in jets from proton-proton collisions at a center-of-mass energy of sqrt(s) = 7 TeV at the CERN Large Hadron Collider. The measurement is based on a data sample recorded with the ATLAS detector with an integrated luminosity of 0.30 pb^-1 for jets with transverse momentum between 25 and 70 GeV in the pseudorapidity range |eta| < 2.5. D*+/- mesons found in jets are fully reconstructed in the decay chain: D*+ -> D0pi+, D0 -> K-pi+, and its charge conjugate. The production rate is found to be N(D*+/-)/N(jet) = 0.025 +/- 0.001(stat.) +/- 0.004(syst.) for D*+/- mesons that carry a fraction z of the jet momentum in the range 0.3 < z < 1. Monte Carlo predictions fail to describe the data at small values of z, and this is most marked at low jet transverse momentum.Comment: 10 pages plus author list (22 pages total), 5 figures, 1 table, matches published version in Physical Review

Search for supersymmetry in final states with jets, missing transverse momentum and one isolated lepton in sqrt{s} = 7 TeV pp collisions using 1 fb-1 of ATLAS data

We present an update of a search for supersymmetry in final states containing jets, missing transverse momentum, and one isolated electron or muon, using 1.04 fb^-1 of proton-proton collision data at sqrt{s} = 7 TeV recorded by the ATLAS experiment at the LHC in the first half of 2011. The analysis is carried out in four distinct signal regions with either three or four jets and variations on the (missing) transverse momentum cuts, resulting in optimized limits for various supersymmetry models. No excess above the standard model background expectation is observed. Limits are set on the visible cross-section of new physics within the kinematic requirements of the search. The results are interpreted as limits on the parameters of the minimal supergravity framework, limits on cross-sections of simplified models with specific squark and gluino decay modes, and limits on parameters of a model with bilinear R-parity violation.Comment: 18 pages plus author list (30 pages total), 9 figures, 4 tables, final version to appear in Physical Review

Reducing heterotic M-theory to five dimensional supergravity on a manifold with boundary

This paper constructs the reduction of heterotic $M$-theory in eleven dimensions to a supergravity model on a manifold with boundary in five dimensions using a Calabi-Yau three-fold. New results are presented for the boundary terms in the action and for the boundary conditions on the bulk fields. Some general features of dualisation on a manifold with boundary are used to explain the origin of some topological terms in the action. The effect of gaugino condensation on the fermion boundary conditions leads to a `twist' in the chirality of the gravitino which can provide an uplifting mechanism in the vacuum energy to cancel the cosmological constant after moduli stabilisation.Comment: 16 pages, RevTe

Measurement of tau polarization in W->taunu decays with the ATLAS detector in pp collisions at sqrt(s) = 7 TeV

In this paper, a measurement of tau polarization in W->taunu decays is presented. It is measured from the energies of the decay products in hadronic tau decays with a single final state charged particle. The data, corresponding to an integrated luminosity of 24 pb^-1, were collected by the ATLAS experiment at the Large Hadron Collider in 2010. The measured value of the tau polarization is Ptau = -1.06 +/- 0.04 (stat) + 0.05 (syst) - 0.07 (syst), in agreement with the Standard Model prediction, and is consistent with a physically allowed 95% CL interval [-1,-0.91]. Measurements of tau polarization have not previously been made at hadron colliders.Comment: 10 pages plus author list (25 pages total), 4 figures, 4 tables, revised author list, matches published EPJC versio

Применение препарата имихимод в лекарственной форме крем 5% в терапии базально-клеточного рака кожи

Objective. To estimate efficiency and safety of application of a preparation of Aldara (imiquimod, 5% external application cream) it is independent or in combination with cryotherapy in therapy of the basal cell carcinoma of the skin (BCC). Material and methods. Research included 78 patients (22 women and 56 men) with various forms of a basal cell carcinoma of the skin. All patients were divided into 3 groups: the main group (n = 30) the patients receiving therapy by Aldara (imiquimod, 5% external application cream) made, second (n = 21) - the patients receiving therapy by Aldara’s, and also 1 course of cryotherapy, and the group of comparison (n = 27) receiving therapy of placebo in the form of external application cream. Therapy was carried out 3 times a week, within 16 weeks. Research was conducted in some stages with histologic confirmation of the diagnosis, and also an assessment of efficiency of therapy and undesirable effects. Results. At 27 of 30 patients of the first group (90%) and at 21 of 21 patients of the second group (100%) receiving treatment by Aldara’s absolute clinical recovery is reached. In group of comparison of clinical recovery at all 27 patients it wasn’t observed. It is expedient to note that at all patients of the second group (100%) already to 75 ± to the 2nd day of therapy (the 4th visit) clinical recovery while at 27 of 30 patients of the first group (90%) the total disappearance (clinical recovery) came for 105 and more days (the 5th and 6th visits) was noted. Recurrence of a disease after the end of therapy it wasn’t observed. Conclusion. Aldara (imiquimod, 5% external application cream) possesses high efficiency at therapy of various forms and sizes of BCC. Undesirable effects of therapy are easily resolved at cancellation of a preparation and not observed at its renewal. Unlike other immunomodulatory preparations (corticosteroids, retinoid, cyclosporin) Aldar’s application doesn’t promote suppression of cellular immunity.Оценить эффективность и безопасность применения препарата Алдара (имихимод, 5% крем для наружного применения) самостоятельно или в сочетании с криотерапией в терапии базально-клеточного рака кожи (БКРК). Материал и методы. В исследование были включены 78 пациентов (22 женщины и 56 мужчин) с различными формами базально-клеточного рака кожи. Все пациенты были разделены на 3 группы: основную группу (n = 30) составили больные, получавшие терапию препаратом Алдара (имихимод, 5% крем для наружного применения), вторую (n = 21) - пациенты, получавшие терапию препаратом Алдара, а также 1 курс криотерапии, и группу сравнения (n = 27) - пациенты, получавшие терапию плацебо в форме крема для наружного применения. Терапия проводилась 3 раза в неделю, в течение 16 недель. Исследование проводилось в несколько этапов с гистологическим подтверждением диагноза, а также оценкой эффективности терапии и нежелательных эффектов. Результаты. У 27 из 30 больных первой группы (90%) и у 21 из 21 пациента второй группы (100%), получавших лечение препаратом Алдара, достигнуто полное клиническое выздоровление. В группе сравнения клинического выздоровления у всех 27 больных не наблюдалось. Целесообразно отметить, что у всех больных второй группы (100%) уже к 75 ± 2 дню терапии (4-й визит) отмечалось клиническое выздоровление, в то время как у 27 из 30 больных первой группы (90%) клиническое выздоровление наступало на 105-й и более дни (5-й и 6-й визиты). Рецидивов заболевания после окончания терапии не наблюдалось. Заключение. Алдара (имихимод, 5% крем для наружного применения) обладает высокой эффективностью при терапии различных форм и размеров БКРК. Нежелательные эффекты терапии легко разрешаются при отмене препарата и не наблюдаются при ее возобновлении. В отличие от других иммуномодулирующих препаратов (кортикостероидов, ретиноидов, циклоспорина) применение препарата Алдара не способствует подавлению клеточного иммунитета

Measurement of the correlation between flow harmonics of different order in lead-lead collisions at √sNN = 2.76 TeV with the ATLAS detector

Correlations between the elliptic or triangular flow coefficients vm (m=2 or 3) and other flow harmonics vn (n=2 to 5) are measured using √sNN=2.76 TeV Pb+Pb collision data collected in 2010 by the ATLAS experiment at the LHC, corresponding to an integrated luminosity of 7 μb−1. The vm−vn correlations are measured in midrapidity as a function of centrality, and, for events within the same centrality interval, as a function of event ellipticity or triangularity defined in a forward rapidity region. For events within the same centrality interval, v3 is found to be anticorrelated with v2 and this anticorrelation is consistent with similar anticorrelations between the corresponding eccentricities, ε2 and ε3. However, it is observed that v4 increases strongly with v2, and v5 increases strongly with both v2 and v3. The trend and strength of the vm−vn correlations for n=4 and 5 are found to disagree with εm−εn correlations predicted by initial-geometry models. Instead, these correlations are found to be consistent with the combined effects of a linear contribution to vn and a nonlinear term that is a function of v22 or of v2v3, as predicted by hydrodynamic models. A simple two-component fit is used to separate these two contributions. The extracted linear and nonlinear contributions to v4 and v5 are found to be consistent with previously measured event-plane correlations

Readiness of the ATLAS liquid argon calorimeter for LHC collisions

The ATLAS liquid argon calorimeter has been operating continuously since August 2006. At this time, only part of the calorimeter was readout, but since the beginning of 2008, all calorimeter cells have been connected to the ATLAS readout system in preparation for LHC collisions. This paper gives an overview of the liquid argon calorimeter performance measured in situ with random triggers, calibration data, cosmic muons, and LHC beam splash events. Results on the detector operation, timing performance, electronics noise, and gain stability are presented. High energy deposits from radiative cosmic muons and beam splash events allow to check the intrinsic constant term of the energy resolution. The uniformity of the electromagnetic barrel calorimeter response along eta (averaged over phi) is measured at the percent level using minimum ionizing cosmic muons. Finally, studies of electromagnetic showers from radiative muons have been used to cross-check the Monte Carlo simulation. The performance results obtained using the ATLAS readout, data acquisition, and reconstruction software indicate that the liquid argon calorimeter is well-prepared for collisions at the dawn of the LHC era.ATLAS Collaboration, for complete list of authors see http://dx.doi.org/10.1140/epjc/s10052-010-1354-y</p
