description: Although the community structure organization is one of the most important characteristics of real-world networks, the traditional network models fail to reproduce the feature. Therefore, the models are useless as benchmark graphs for testing community detection algorithms. They are also inadequate to predict various properties of real networks. With this paper we intend to fill the gap. We develop an exponential random graph approach to networks with community structure. To this end we mainly built upon the idea of blockmodels. We consider both, the classical blockmodel and its degree-corrected counterpart, and study many of their properties analytically. We show that in the degree-corrected blockmodel, node degrees display an interesting scaling property, which is reminiscent of what is observed in real-world fractal networks. The scaling feature comes as a surprise, especially that in this study, contrary to what is suggested in the literature, the scaling property is not attributed to any specific network construction procedure. It is an intrinsic feature of the degree-corrected blockmodel. A short description of Monte Carlo simulations of the models is also given in the hope of being useful to others working in the field.

Разра-ботаны математические модели формирования гармоничного МТП.
description: In connection with the need for comprehensive accounting of many industrial, technical, agro-nomic, organizational and personnel factors and the disclosure of the internal mechanism of the formation of a positive effect in the park, a new concept was introduced - the harmony of the machine and tractor fleet. The main principles of the implementation of harmonization are iden-tified. Harmony - the highest level of compliance of the ICC with the natural-climatic, industrial, financial, organizational and human resources of the economy. The estimated main factors af-fecting the efficiency of the machine and tractor fleet are identified, and the structure of the formation a harmonious machine and tractor fleet is presented. Developed mathematical models of the formation of a harmonious machine and tractor fleet.
On the evolution of the snow line in protoplanetary discs II: Analytic approximations

description: We examine the evolution of the snow line in a protoplanetary disc that contains a dead zone (a region of zero or low turbulence). The snow line is within a self-gravitating part of the dead zone, and we obtain a fully analytic solution for its radius. Our formula could prove useful for future observational attempts to characterise the demographics of planets outside the snow line. External sources such as comic rays or X-rays from the central star can ionise the disc surface layers and allow the magneto-rotational instability to drive turbulence there. We show that provided that the surface density in this layer is less than about 50 g/cm^2, the dead zone solution exists, after an initial outbursting phase, until the disc is dispersed by photoevaporation. We demonstrate that the snow line radius is significantly larger than that predicted by a fully turbulent disc model, and that in our own solar system it remains outside of the orbital radius of the Earth. Thus, the inclusion of a dead zone into a protoplanetary disc model explains how our Earth formed with very little water.

description: A partir de la informacion recogida en una investigacion realizada entre universidades alemanas y cubanas, se analiza en este articulo la introduccion del modelo cooperativista en la agricultura cubana en 1993, y se hace balance del desarrollo de las UBPC (unidades basicas de produccion cooperativa). En primer lugar, analiza los problemas estructurales de la agricultura cubana y la dependencia alimentaria heredada de la epoca anterior a la revolucion castrista. En segundo lugar, analiza las causas del fracaso del Programa Alimentario de 1989, como precedente de las reformas introducidas en 1993 en lo que algunos autores han denominado "nueva reforma agraria". Finalmente, el autor expone una serie de reflexiones personales sobre las posibilidades de consolidacion de estas nuevas formas de cooperativismo en Cuba, y plantea las actuaciones de politica agraria que serian necesarias para que las UBPC se conviertan en un elemento fundamental del desarrollo rural en Cuba.

description: Background: Producing sounds by a musical instrument can lead to audiomotor coupling, i.e. the joint activation of the auditory and motor system, even when only one modality is probed. The sonification of otherwise mute movements by sounds based on kinematic parameters of the movement has been shown to improve motor performance and perception of movements.Results: Here we demonstrate in a group of healthy young non-athletes that congruently (sounds match visual movement kinematics) vs. incongruently (no match) sonified breaststroke movements of a human avatar lead to better perceptual judgement of small differences in movement velocity. Moreover, functional magnetic resonance imaging revealed enhanced activity in superior and medial posterior temporal regions including the superior temporal sulcus, known as an important multisensory integration site, as well as the insula bilaterally and the precentral gyrus on the right side. Functional connectivity analysis revealed pronounced connectivity of the STS with the basal ganglia and thalamus as well as frontal motor regions for the congruent stimuli. This was not seen to the same extent for the incongruent stimuli.Conclusions: We conclude that sonification of movements amplifies the activity of the human action observation system including subcortical structures of the motor loop. Sonification may thus be an important method to enhance training and therapy effects in sports science and neurological rehabilitation.

description: Based on a cognitive–motivational modeling of construct relations, this study analyzed the role of prior statistics experiences within a framework of domain-specific self-concept and value variables to predict education science students’ statistics anxiety. Data were analyzed from two independent samples comprising 113 and 87 participants—using the passing of a statistics exam as the experience measure in each case. In both samples, the results of three-way analyses of variance demonstrated students’ statistics anxiety to be substantially explained by their negative utility value and self-concept but only to a minor extent by their prior statistics experiences. Students’ statistics anxiety appeared to be dependent on value and self-concept scores across all experience levels. Though producing somewhat varying effect patterns, the findings from both samples led to similar effects, indicating the crucial role of self-belief variables. Results are discussed in terms of conceptual, methodological, and instructional implications.

description: Over the past 20 years, fullerides have been studied as the source of high-transition-temperature (Tc) superconductivity except for copper oxides. The recent finding of the Mott insulating state right beside superconductivity in Cs3C60 has suggested that magnetism helps raise Tc even in fullerides as in heavy-fermion compounds, high-Tc copper oxides, two-dimensional organic conductors, and iron pnictides. Namely, one tends to think that the link between Mott insulator and superconductivity takes place in fullerides, which can give rise to the mechanism beyond the Bardeen-Cooper-Schrieffer framework. However, the relationship between the Mott state and the superconductivity in Cs3C60 is still under debate. By nuclear magnetic resonance measurements under pressure, we find that the magnetism and superconductivity in Cs3C60 are competing orders. Different from previous reports, the phase separation of Cs3C60 crystals into the Mott and metallic states allows us to systematically study the evolution of the ground state under pressure. Our careful experiments have found that the prevention of a magnetic order is rather essential for the superconductivity in face-centred cubic Cs3C60, which presents a basic strategy for finding still higher Tc in this system.

description: Potato late blight, caused by Phytophthora infestans Mont. de Bary, is one of the most important problems for both, conventional and organic potato growers. Since fungicide protection is not possible in organic agriculture, the only way to combat with this pathogen is growing of resistant cultivars. However, the number of cultivars combining good level of agronomical characteristics with very high level of late blight resistance is still far insufficient. In the frame of Ecobreed project 65 potato cultivars hypothetically suitable for organic conditions were selected and assessed in terms of its resistance against late blight. Among these cultivars only 17 showed very high level of late blight resistance which allows to grow them without chemical protection. All these cultivars possess an R genes, which are considered to be highly effective since provide resistance against broad spectrum of P. infestans races. Unfortunately, in most cases these genes appeared in cultivars singly (or combined with low-effective R-genes) which can decrease durability of effective resistance provided by such genes. It is believed that pyramiding of the broad-spectrum resistance genes can help to produce potato cultivars durably resistant to late blight, because it is less likely for a pathogen to simultaneously gain virulence towards a plant with several highly effective R-genes. Therefore, donors of various broad-spectrum resistance genes were crossed, and progenies with pyramided R-genes were selected. Since phenotypical selection of such genotypes requires use of many different isolates of the pathogen, the use of marker assisted selection (MAS) was also applied. This method proved to be highly effective in selection of potato individuals combining two or more R-genes and will be broadly applied in the next stages of Ecobreed project.

description: While organic farming is well established in Europe a nd USA, it is still catching up in Asian countries. The government of South Korea has implemented environmentally friendly farming that encompasses organic farming. Despite the promotion of environmentally friendly farming, it still has a low share in South Korea and partially converted farming has emerged in some districts of South Korea. However, the partially converted farming has not yet been investigated by the government. Thus, our study implemented a financial analysis to compare the annual costs and net returns of conventional, partially converted and environmentally friendly farming in Gangwon Province. The result showed that environmentally friendly farming was more profitable with respect to farm net returns. To find out the factors affecting the adoption of environmentally friendly farming, multinomial logistic regression was implemented. The findings revealed that education and subsidy positively and significantly influenced the probability of farmers' choice on partially converted and environmentally friendly farming. Farm size had a negative and significant relationship with only environmentally friendly farming. This study will contribute to future policy establishment for sustainable agriculture as recommended by improving the quality of fertilizers, suggesting the additional investigation associated with partially converted farmers. © 2016 by the authors; licensee MDPI, Basel, Switzerland.

description: BACKGROUND: Allergic Rhinitis (AR) is a common disorder in Europe with Allergic Asthma (AA) as a frequent comorbidity. Allergy immunotherapy (AIT) is the only causal therapy of AR and AA, and can be administered as subcutaneous injections at the physician or as sublingual drops or tablets at home. The usual treatment duration is 3 years. OBJECTIVE: This study aimed to elicit patient preferences to identify the AIT administration mode preferred by patients.METHODS: A discrete-choice-experiment (DCE) was developed to determine how people weight different treatment options using a paper-based questionnaire from June to September 2014, including 16 study centres. Main inclusion criteria: >18 years, grass, birch and/or house dust mite AR with moderate to severe symptoms, AIT-naïve and AIT-indicated. DCE-attributes were: Administration form, number and duration of physician visits, frequency of life-threatening anaphylactic shocks, local side-effects and co-payments. RESULTS: Two-hundred thirty-nine subjects participated, resulting in analysable 1842 choices. All attributes were significant predictors for the treatment-choice. Ranked by importance, the following first three attributes are most preferred by patients: 1(st) Number and duration of physician visits: Fewer visits with shorter duration preferred (0.658*) 2(nd) Frequency of life-threatening anaphylactic shocks: Lower risk of shocks preferred (0.285*) 3(rd) Local side-effects: Preference for rash/swelling on upper arm over itching/swelling under the tongue (0.210*) (*coefficient-size represents relative importance of the attributes). CONCLUSION: The most important attribute is the number and duration of visits to a physician. A lower risk of life-threatening anaphylactic shocks was ranked as the second whereas co-payments and administration form play a limited role.

description: We report the phase-space defined by the quantum Hall effect breakdown in polymer gated epitaxial graphene on SiC (SiC/G) as a function of temperature, current, carrier density, and magnetic fields up to 30T. At 2K breakdown currents ($I_c$) almost two orders of magnitude greater than in GaAs devices are observed. The phase boundary of the dissipationless state ($ρ_{xx}=0$) shows a (1-$(T/T_c)^2$) dependence and persists up to $T_c>45K$ at 29T. With magnetic field $I_c$ was found to increase $\propto B^{3/2}$ and $T_c \propto B^{1.88}$. As the Fermi energy approaches the Dirac point, the $ν=2$ quantized Hall plateau appears continuously from fields as low as 1T up to at least 19T due to a strong magnetic field dependence of the carrier density.

description: This research explores the solution based synthesis of functional nanorods and nanowire compositions and the use of electron microscopy techniques to elucidate growth and phase transformations in these nanostructures. The electron microscopy investigations were performed primarily through aberration corrected TEM combined with EDX and in-situ TEM.Chapter 1 gives an introduction to one- dimensional nanorods and nanowires, including their properties, characterisation and applications. Their growth mechanisms and synthesis techniques are also discussed. The general synthesis methods and characterisation techniques of the nanostructures produced within this work are detailed in Chapter 2.Chapter 3 reports the synthesis of axial heterostructure Si and Ge (hSG) nanowires (NWs). The NWs were grown from a low-cost Sn powder to achieve a powder form product representing an attractive route from lab-scale to commercial application. Atomic resolution STEM imaging and EDX mappings were used to analyse the interfacial abruptness at the NW heterojunction and the planar defects present in the NWs. The electrochemical performance of these hSG NWs as anodes in a Li-ion battery was examined as a potential anode material to replace standard graphite anodes. The structural evolution and phase changes in the hSG NWs due to Li cycling were also investigated using TEM and EDX.The use of in situ TEM techniques to track reaction chemistry in nanostructured materials is demonstrated in Chapters 4 and 5.In Chapter 4, building on the solution based synthesis approach, heterostructure NWs comprising Ni stem and branched Si NWs were grown. In-situ heating TEM experiments were conducted to investigate Ni diffusion and phase transformation in the NWs, where the Ni atoms were supplied from the Ni stem. In situ monitoring of the heating of the NW sample provided unparalleled insights into the role of NW morphology and defect distribution on the rate of Ni diffusion and phase being formed.Chapter 5 focusses on the in-situ liquid cell TEM investigations of self-assembly processes of nanorods suspended in organic solvents. Cadmium Sulphide nanorods (CdS NRs) were used as a model system. These NRs undergo oriented attachment to form CdS NWs when posttreated with octylamine. Liquid cell TEM was used to dynamically probe the dynamics of CdS NRs in real-time under external stimuli such as reactant flow (octylamine) and electron beam irradiation. The results showed how different environmental stimuli influence the dynamics of CdS NRs, from end-to-end NR attachments to the formation of side-by-side NR chains and vertically aligned self-assembled NRs.Chapter 6 provides conclusions for each chapter and recommendations for future research on the work completed in this thesis.

description: It is not understood whether long-lived star clusters possess a continuous range of sizes and masses (and hence densities), or if rather, they should be considered as distinct types with different origins. Utilizing the Hubble Space Telescope (HST) to measure sizes, and long exposures on the Keck 10m telescope to obtain distances, we have discovered the first confirmed star clusters that lie within a previously claimed size-luminosity gap dubbed the `avoidance zone' by Hwang et al (2011). The existence of these star clusters extends the range of sizes, masses and densities for star clusters, and argues against current formation models that predict well-defined size-mass relationships (such as stripped nuclei, giant globular clusters or merged star clusters). The red colours of these gap objects suggests that they are not a new class of object but are related to Faint Fuzzies observed in nearby lenticular galaxies. We also report a number of low luminosity UCDs with sizes of up to 50 pc. Future, statistically complete, studies will be encouraged now that it is known that star clusters possess a continuous range of structural properties.

description: BACKGROUND: Identifying patient priorities and preference measurements have gained importance as patients claim a more active role in health care decision making. Due to the variety of existing methods, it is challenging to define an appropriate method for each decision problem. This study demonstrates the impact of the non-standardized Analytic Hierarchy Process (AHP) method on priorities, and compares it with Best-Worst-Scaling (BWS) and ranking card methods. METHODS: We investigated AHP results for different Consistency Ratio (CR) thresholds, aggregation methods, and sensitivity analyses. We also compared criteria rankings of AHP with BWS and ranking cards results by Kendall's tau b. RESULTS: The sample for our decision analysis consisted of 39 patients with rare diseases and mean age of 53.82 years. The mean weights of the two groups of CR = 0.1 and CR = 0.2 did not differ significantly. For the aggregation by individual priority (AIP) method, the CR was higher than for aggregation by individual judgment (AIJ). In contrast, the weights of AIJ were similar compared to AIP, but some criteria's rankings differed. Weights aggregated by geometric mean, median, and mean showed deviating results and rank reversals. Sensitivity analyses showed instable rankings. Moderate to high correlations between the rankings resulting from AHP and BWS. LIMITATIONS: Limitations were the small sample size and the heterogeneity of the patients with different rare diseases. CONCLUSION: In the AHP method, the number of included patients is associated with the threshold of the CR and choice of the aggregation method, whereas both directions of influence could be demonstrated. Therefore, it is important to implement standards for the AHP method. The choice of method should depend on the trade-off between the burden for participants and possibilities for analyses.

description: При построении любой информационной структуры требуется учитывать ее безопас-ность, так как в современном обществе владение любой информацией может принести определенную выгоду. Поэтому вопрос безопасности информационной системы является определяющим фактором качества данной системы. Наиболее остро проблема безопасно-сти стоит в облачных технологиях, где информация находится не на носителях пользова-теля, а на общих серверах и ресурсах и передается через сеть интернет. Обеспечить без-опасность такой структуры – непростая задача, еще более сложная задача сохранить при этом высокую производительность данной системы. В данной статье будет рассмотрена избыточная система остаточных классов (СОК) и возможность ее применения в облачных вычислениях.
description: When building any information structure, it is necessary to take into account its security, since in modern society, the possession of any information can bring certain benefits. Therefore, the issue of security of an information system is a determining factor in the quality of a given sys-tem. The most acute security problem is in cloud technologies, where information is not on us-er’s media, but on shared servers and resources and is transmitted via the Internet. Ensuring the safety of such a structure is not an easy task, it is even more difficult to preserve the high per-formance of this system. In this article, we consider the redundant residue number system (RNS) and the possibility of its application in cloud computing.

description: Oncolytic virotherapy - the use of viruses that specifically kill tumor cells - is an innovative and highly promising route for treating cancer. However, its therapeutic outcomes are mainly impaired by the host immune response to the viral infection. In the present work, we propose a multiscale mathematical model to study how the immune response interferes with the viral oncolytic activity. The model assumes that cytotoxic T cells can induce apoptosis in infected cancer cells and that free viruses can be inactivated by neutralizing antibodies or cleared at a constant rate by the innate immune response. Our simulations suggest that reprogramming the immune microenvironment in tumors could substantially enhance the oncolytic virotherapy in immune-competent hosts. Viable routes to such reprogramming are either in situ virus-mediated impairing of CD$8^+$ T cells motility or blockade of B and T lymphocytes recruitment. Our theoretical results can shed light on the design of viral vectors or new protocols with neat potential impacts on the clinical practice.

description: We develop a general method allowing one to construct the consistent theory of light pulse propagation through an atomic medium in arbitrary nonlinear regime with respect to the field strength, taking into account the light polarization, temporal (frequency) and spatial dispersions. The method is based on the reduced Maxwell equation, atomic density matrix formalism and adiabatic approximation. In order to demonstrate the efficiency of our method we investigate in detail the case of propagation of the polarization pulse under conditions of coherent population trapping in a medium of two-level atoms with degenerate energy levels. Equations describing the evolution of various field parameters are derived. It is shown that pulses of ellipticity and spatial orientation of polarization ellipse propagate with slowing. Analytical expressions for the slowing factor are obtained. A previously unknown effects of the stimulated phase modulation and the generation of a phase pilot pulse by the variation of spatial orientation of the polarization ellipse are predicted. In addition, we show that the spatial dispersion can be interpreted as "wind effects".

description: BACKGROUND: Regional differences in physician supply can be found in many health care systems, regardless of their organizational and financial structure. A theoretical model is developed for the physicians' decision on office allocation, covering demand-side factors and a consumption time function. METHODS: To test the propositions following the theoretical model, generalized linear models were estimated to explain differences in 412 German districts. Various factors found in the literature were included to control for physicians' regional preferences. RESULTS: Evidence in favor of the first three propositions of the theoretical model could be found. Specialists show a stronger association to higher populated districts than GPs. Although indicators for regional preferences are significantly correlated with physician density, their coefficients are not as high as population density. CONCLUSIONS: If regional disparities should be addressed by political actions, the focus should be to counteract those parameters representing physicians' preferences in over- and undersupplied regions.

description: Background: The regional availability of specialized physicians is an important aspect in healthcare of patients with IBD. The association between physician density and healthcare is not yet clear. Most studies did not consider district type, which reflects population density. Our research question was, “Do specialist density and district type influence the healthcare of IBD patients in Germany?” Methods: We combined a claims dataset from a German health insurance fund with population and physician data. Four main aspects were investigated: regular specialist visits, drug therapies, surveillance colonoscopy, and IBD-related hospitalizations. Various regression analyses were performed. Results: The study cohort was comprised of 21,771 individuals, including 9282 patients with Crohn disease and 12,489 patients with ulcerative colitis. Patients who were living in districts with higher specialist densities were more likely to attend specialist visits on a regular basis. No difference in the frequencies of TNF-alpha inhibitor therapies was found. However, individuals from urban areas were more likely to receive a permanent immunosuppressive therapy with continuous specialist support. Conclusions: The results revealed that some aspects had positive effects on the probability of implementing healthcare in accordance with pathways and guidelines. No clear evidence of a general healthcare undersupply in rural areas was found.
