Published: July 2019

ZusammenfassungZiel Bundesweit gibt es 19 Modellvorhaben nach §64b SGB V (MV), die eine settingübergreifende und flexible psychiatrische Behandlung anbieten. In Schleswig-Holstein (SH) haben sich fünf dieser Modelle gebildet. In einer vergleichenden Analyse wird die Implementierung der MV in SH gegenüber dem Bundesgebiet untersucht.Methodik Standardisierte Befragung von 383 Patienten aus sieben Kliniken, davon drei aus SH, zur Beurteilung der Modellversorgung. Es wurden Struktur-, Leistungs- sowie Daten zum Implementierungsstand von MV in SH und den übrigen Bundesländern analysiert.Ergebnisse MV in SH weisen eine stärkere Ausprägung modellspezifischer Merkmale und einen höheren Implementierungsgrad gegenüber der Vergleichsgruppe auf. Sie befinden sich in öffentlicher Trägerschaft und sind mit allen Krankenkassen verhandelt. Patienten dieser MV werden häufiger ambulant oder aufsuchend behandelt, verfügen über mehr Erfahrung mit spezifischen Aspekten der MV und bewerten diese besser.Schlussfolgerung Die Implementierung der MV in SH kann als besonders erfolgreich angesehen werden. Unter anderem scheint die Unterstützung der Landespolitik eine entscheidende Triebkraft hierfür zu sein.

Authors: Ram Ganesan G. , Govardhan Praveen 
Published: July 2019

Context In India, hip fracture crude incidence above the age of 50 years was 129 per 100,000.
Aims The aim of this study is to analyze the in-hospital mortality following proximal femur fractures in elderly Indian population.
Methods and Material The study was done in Sri Ramachandra Medical Center, Chennai, India. Patient's records were retrospectively evaluated for a period of 3 years from January 1, 2015 to January 1, 2018. The inclusion criteria were patients both male and female aged more than 65 years admitted with the diagnosis of neck of femur or intertrochanteric or subtrochanteric fractures. The exclusion criteria were patients having any associated fracture or previous hip fracture history or diagnosed primary or secondary malignancies. To evaluate any surgical delay two groups were formed. After eliminating cases based on exclusion criteria, we had 270 patients for evaluation.
Statistical Analysis Used The collected data were analyzed with IBM.SPSS statistics software 23.0 Version. To describe about the data descriptive statistics frequency analysis, percentage analysis were used for categorical variables and the mean and standard deviation (SD) were used for continuous variables. To find the significant difference between the bivariate samples, Student's t-test and analysis of variance (ANOVA) were used. The p-value of 0.05 is considered as significant level.
Results We had a total of 24 mortalities with 15 males and 9 females. The in-hospital mortality of patients who underwent replacement surgeries for proximal femur fractures was 14 in our study. Sixteen of the in-hospital mortality patients had low Parker's mobility score. Twenty patients had mortality when surgery was delayed more than 48 hours.
Conclusions In-hospital mortality in elderly patients having proximal femur fracture increases significantly if the patient was having low-preoperative mobility status, if surgery was delayed more than 48 hours, and if patient undergoes replacement surgeries.
Actinomyces Meyeri Empyema Necessitatis—A Case Report and Review of the Literature
Authors: Ellebrecht David B. , Pross Moritz M.F. , Schierholz Stefanie , Palade Emanuel 
Published: July 2019

Pleural empyema necessitatis caused by Actinomyces meyeri is a rare but severe infection. A. species predominantly A. meyeri and A. israelii represent the second most common pathogen for empyema necessitans after mycobacteria. The incidence is reported in the literature to be 1:300,000. Men are thrice more likely to be affected than women. Pathogenetically, an infection can be triggered by aspiration in immunocompromised individuals which leads to an atelectasis with pneumonitis.In two cases, a 38-year-old construction worker and a 61-year-old woman with ulcerative breast carcinoma, who presented to the local emergency department with a painful swelling of the left chest, diagnostic workup revealed a pleural empyema necessitatis of the left chest. An antibiotic treatment was initiated with piperacillin/tazobactam and sulbactam/ampicillin, respectively. Temporally vacuum-dressing therapy was initiated after surgical debridement. In the course of the procedure, a reconstruction of tissue damage was feasible. The patients were recovered completely and discharged with an oral antibiotic treatment (amoxicillin) for 6 and 12 months, respectively.Thoracic actinomycosis is a relatively uncommon and traditionally chronic, indolent infection secondary to pulmonary infection with A. species. Surgical treatment is generally reserved for cases failing to resolve with antibiotic therapy. Early diagnosis, prompt debridement, and narrow spectrum β-lactam antibiotics can result in complete resolution of infection and good prognosis.
Variability of signal sequences in turn-taking exchanges induces agency attribution in 10.5-mo-olds
Authors: Tauzin Tibor , Gergely György 
Published: July 2019

SignificanceWe demonstrate that 10.5-mo-old infants—before understanding the symbolic contents encoded by unfamiliar signals—can recognize turn-taking interactions that serve communicative information transmission based on detecting variability in the signal sequences exchanged. Sensitivity to this abstract structural cue is sufficient to attribute communicative abilities and intentional agency to the interacting entities, as indicated by gaze following the agent’s object-oriented turning to fixate its distal referent. When the entities exchanged identical signals only, no gaze following and agency attribution occurred. Infants’ early sensitivity to variability in exchanged signal sequences can play an important role in social-cognitive development and language acquisition by helping infants recognize communicative interactions that can convey relevant information in various pragmatic contexts.

Published: July 2019

Significance
Mesenchymal stem cell (MSC) therapies have shown strong preclinical promise, particularly in ameliorating diseases of immune dysregulation. However, these results have largely failed to demonstrate efficacy in clinical settings, likely due to large dosages necessitated by the short residence time of infused cells, suboptimal cell phenotype, and immune rejection. We demonstrate that a microfluidic-based biomaterial encapsulation approach can increase in vivo residence time after intravenous (i.v.) delivery by more than an order of magnitude. Encapsulated cells up-regulated immunomodulatory genes upon exposure to inflammatory cytokines and promoted engraftment of major histocompatibility complex (MHC)-mismatched donor cells in a bone marrow transplant model. The ability to retain i.v. infused MSCs for longer durations may be broadly applicable toward improving MSC therapies.

Published: July 2019

Significance
Type-1 reactions (T1R) are pathological immune responses in leprosy and a frequent cause of peripheral nerve damage. Employing a candidate gene approach combined with deep resequencing, we identified amino acid mutations in the E3 ligase Parkin and the polyfunctional kinase LRRK2 that were associated with T1R. This finding directly linked both proteins with the extent of the immune response in an infectious disease. Moreover, amino acids associated with T1R mutations were significantly enriched for mutations found in patients suffering from Parkinson’s disease (PD). These findings confirm Parkin and LRRK2 as 2 key inflammatory regulators and suggest that T1R and PD share overlapping pathways of pathogenesis.
Cubic Auto-Catalysis Reactions in Three-Dimensional Nanofluid Flow Considering Viscous and Joule Dissipations Under Thermal Jump
Authors: Kumar Rakesh , Kumar Ravinder , Koundal Reena , Shehzad Sabir Ali , Sheikholeslami Mohsen 
Published: July 2019

Abstract

In this problem, simultaneous effects of Joule and viscous dissipation in three-dimensional flow of nanoliquid have been addressed in slip flow regime under time dependent rotational oscillations. Silver nanoparticles are submerged in the base fluid (water) due to their chemical and biological features. To increment the novelty, effects of cubic autocatalysis chemical reactions and radiative heat transfer have been incorporated in the related boundary layer equations. Dimensionless partial differential system is solved by employing the proposed implicit finite difference approach. Convergence conditions and stability criteria are obtained to ensure the convergence and accuracy of solutions. A comparative analysis is proposed for no-slip nanofluid flow (NSNF) and slip nanofluid flow (SNF). Variations in skin-friction coefficients, Sherwood and Nusselt numbers against physical parameters are tabulated. It is investigated that velocity slip and temperature jump significantly control drag forces and rate of heat transfer.
Heisenberg-Type Quantum Steering by Continuous Weak Measurement in Circuit QED*
Authors: Wang Zhong 
Published: July 2019

Abstract

Quantum steering has attracted great interest in the last decade, especially in the celebrated optomechanical, cold atom, and quantum optical systems. However, there is still a lack of studies on quantum steering in circuit quantum electrodynamics (QED), which provides a useful experimental platform for revealing novel quantum phenomena. In this work, we investigate the steering of qubit by continuous weak measurement in a circuit QED system and establish a set of multiplicative steering inequalities based on the Heisenberg uncertainty principle. Different from the widely studied systems mentioned above, multiplicative steering inequalities in the circuit QED system are in various forms. We find that only a portion of them can be used to show the detection dependence of the qubit state and we also analyze the reason. Furthermore, we discuss several conditions for the violation of a typical steering inequality, including the measurement strength and methods in detecting the cavity field as well as the quantum efficiency of the detector. This preliminary work could be helpful to quantum steering experiments in circuit QED systems.
A Renormalized-Hamiltonian-Flow Approach to Eigenenergies and Eigenfunctions*
Authors: Wang Wen-Ge 
Published: July 2019

Abstract

We introduce a decimation scheme of constructing renormalized Hamiltonian flows, which is useful in the study of properties of energy eigenfunctions, such as localization, as well as in approximate calculation of eigenenergies. The method is based on a generalized Brillouin-Wigner perturbation theory. Each flow is specific for a given energy and, at each step of the flow, a finite subspace of the Hilbert space is decimated in order to obtain a renormalized Hamiltonian for the next step. Eigenenergies of the original Hamiltonian appear as unstable fixed points of renormalized flows. Numerical illustration of the method is given in the Wigner-band random-matrix model.
Tunable Range Interactions and Multi-Roton Excitations for Bosons in a Bose-Fermi Mixture with Optical Lattices*
Authors: Feng Chao , Chen Yu 
Published: July 2019

Abstract

In this article, we discuss a method to control the long-range interactions between bosons in a three-dimensional Bose-Fermi mixture with the help of optical lattices on fermions. We find the range and the peaked momentum of the fermion-mediated interactions can be tuned by the optical lattice depth and the fermion density. If the fermion density is close to half-filling, roton excitations can be generated with weak Bose-Fermi interactions. Further, if the fermions are not exact at half-filling, multi-roton structure may emerge, implying competing density orders. Therefore, tuning the lattice depth and the fermion density in a Bose-Fermi mixture serves as an effective way to control the interaction range and resonant momentum between bosons.
Three-loop vacuum integral with four-propagators using hypergeometry *
Authors: Gu Zhi-Hua , Zhang Hai-Bin 
Published: July 2019

AbstractA hypergeometric function is proposed to calculate the scalar integrals of Feynman diagrams. In this study, we verify the equivalence between the Feynman parametrization and the hypergeometric technique for the scalar integral of the three-loop vacuum diagram with four propagators. The result can be described in terms of generalized hypergeometric functions of triple variables. Based on the triple hypergeometric functions, we establish the systems of homogeneous linear partial differential equations (PDEs) satisfied by the scalar integral of three-loop vacuum diagram with four propagators. The continuation of the scalar integral from its convergent regions to entire kinematic domains can be achieved numerically through homogeneous linear PDEs by applying the element method.

We explore the Kibble-Zurek scaling of conserved charge using stochastic diffusion dynamics. The characteristic scales

and

are determined and used to properly rescale the traditional correlation function and cumulant. We construct universal functions for the two-point correlation

and the second-order cumulant

of the conserved charge in the critical regime, both of which are, near the critical point, insensitive to both the initial temperature and a parameter in the mapping between the 3D Ising model and the hot QCD system.
Influence of the channel length of a vortex tube on the air temperature separation
Authors: Adiullin B R , Mikhaylenko C I 
Published: July 2019

Abstract
A model of a counterflow vortex tube has been prepared to study the dependence of the influence of the tube length parameter on the cold and hot air production. Computational experiments were made using the OpenFOAM package. The prepared grid allowed us to carry out simulations for vortex tubes with lengths of the main channel varying from 20 to 70 cm. All calculations were performed with boundary conditions with constant inlet pressure and atmospheric pressure at the outlet. Results were obtained on temperatures and mass flow rates of the air in the cold and hot outlets of the vortex tube, depending on the length of the device. It is shown that an increase of the length of the vortex tube channel increases the production of cold air. An increase in the temperature of the produced hot air on vortex tube length increase was also noted.
The influence of difference in the surface properties on the axisymmetric oscillations of an oblate drop
Authors: Alabuzhev A A 
Published: July 2019

Abstract
The forced axisymmetric oscillations of an oblate fluid drop are investigated. A drop is cylindrical in equilibrium, surrounded by another liquid and bounded axially by two parallel solid plates. These plates have different surfaces. Hocking’s boundary conditions hold on the contact line: the velocity of the contact line motion is proportional to the deviation of the contact angle from its equilibrium value. The Hocking’s parameter (so-called wetting parameter) is the proportionality coefficient in this case and it is different for each plate. The vibration force is parallel to the symmetry axis of the drop. The solution of the boundary value problem is found using Fourier series of Laplace operator eigen functions.
Nonlocal strength criteria for the calculation of critical loads in bended structural elements, taking into account the nonlinearity of the material deformation
Authors: Kurguzov V D , Demeshkin A G 
Published: July 2019

Abstract
The destruction of artificial materials (plexiglas, ebonite) in non-uniform stress fields was experimentally investigated. Testing of one batch of samples is carried out using various methods: three-point and clean (four-point) bending of rectangular cross-section beams, Brazilian test (method of splitting a cylinder along a generator). The comparison of the strength characteristics obtained by the Brazilian test with the uniaxial tensile strength, as well as with the tensile strength during bending tests. Experiments on the fracture of beams on a three-point flexural test revealed higher values of ultimate tensile stress than those of a four-point flexural test. The processing of the experimental data obtained by the Brazilian test is carried out using various non-local strength criteria. A sequential analysis of the applicability of the criteria used in the determination of failure loads is carried out. Computer simulation was performed using the finite-element method for the destruction of a cylinder by splitting along a generator, three-point and four-point bending flexural test of a beam in a geometrically nonlinear formulation, taking into account the non-linearity of the material deformation diagram. The problem was solved in the updated Lagrangian formulation taking into account the physical and geometric nonlinearity based on the governing equations of the hypoelastic material. A comparative analysis of the numerical, analytical and experimental results is carried out. A qualitative correspondence was obtained between the experimental data and the results of numerical calculations.
Dependence of tsunami wave maximal heights along a coastline on the source orientation
Authors: Lavrentiev M , Lysakov K , Marchuk An , Oblaukhov K , Shadrin M 
Published: July 2019

Abstract
The authors address an important problem of timely evaluation of tsunami danger after offshore underwater earthquake. In case of Japan it takes nearly 20 minutes for the wave to approach the nearest coast after the seismic event. In this paper we continue to study the influence of tsunami source parameters on the distribution of the wave heights along the coast. As a rule, tsunami wave heights have sharp maximums at selected points of the coast. So, after seismic event the wave may be dangerous only at a few locations. Numerical tests show dependence of the distribution of such maximal wave heights from the orientation of the initial sea bed (sea surface) displacement, which has a form close to reconstruction of historic event at South-East of Japan.

Authors: Peregudin Sergey , Peregudina Elina , Kholodova Svetlana 
Published: July 2019

Abstract
The paper constructs the matheamtical model of dynamics of spatial large-scale quasi-geostrophic motions in a rotating layer of ideal incompressible conducting liquid of variable depth with arbitrary values of the magnetic Reynolds number. Our finding can have certain value in astrophysics and geophysics, for example, in the study of processes occurring in stellar interiors and the liquid Earth core; besides, they can be used in evaluating magnetohydrodynamic characteristics of marine environments, in assessing parameters of wave perturbations sources from the electromagnetic field generated by the corresponding hydrodynamic excitement, which contains important information about geophysical characteristics of the shelf zone. This information is relevant for marine geological surveys and studies.
The evolution of non-linear disturbances in magnetohydrodynamic flows
Authors: Proskurin A V , Sagalakov A M 
Published: July 2019

Abstract
In this article the stability loss of the Hartmann flow are investigated by applying the equations for disturbances. The velocity and electric potential quasi-static MHD model is used. The equations allow us to calculate time-dependent disturbance fields using a base flow and an initial disturbance. Two type of initial perturbations are considered: the eigenfunction of the linearized MHD equations and a fluid injection into the flow. These two approaches lead to identical stability results. However, we found a significant difference in the practical implementation of the two approaches. Dealing with the eigenproblem of the linearized MHD system is a laborious task. In terms of calculation costs it is equal to a series of nonlinear perturbation simulations, and if the Hartmann number is increased, the proportion becomes worse. The non-linear stability analysis produced by these two methods shows that the injection technique can also be used in numerical analysis, and that this method is less expensive in terms of calculation costs.

Published: July 2019

Abstract
The aim of this paper is to present the results of a self-consistent model, which allows describing the evolution of temperature and humidity distributions in a spherical sample of porous clay-like material in drying and cooling processes. Due to the isotropy of the studied material, the solutions obtained are nonlinear radial distributions that change with time. The results are in good agreement with the experimental results obtained in the works of other authors.
