Sab concentrations indicate chemotherapeutic susceptibility in ovarian cancer cell lines
Authors: Paudel Iru , Hernandez Sean M. , Portalatin Gilda M. , Chambers Tara P. , Chambers Jeremy W.
Published: October 2018

The occurrence of chemotherapy-resistant tumors makes ovarian cancer (OC) the most lethal gynecological malignancy. While many factors may contribute to chemoresistance, the mechanisms responsible for regulating tumor vulnerability are under investigation. Our analysis of gene expression data revealed that Sab, a mitochondrial outer membrane (MOM) scaffold protein, was down-regulated in OC patients. Sab-mediated signaling induces cell death, suggesting that this apoptotic pathway is diminished in OC. We examined Sab expression in a panel of OC cell lines and found that the magnitude of Sab expression correlated to chemo-responsiveness; wherein, OC cells with low Sab levels were chemoresistant. The Sab levels were reflected by a corresponding amount of stress-induced c-Jun N-terminal kinase (JNK) on the MOM. BH3 profiling and examination of Bcl-2 and BH3-only protein concentrations revealed that cells with high Sab concentrations were primed for apoptosis, as determined by the decrease in pro-survival Bcl-2 proteins and an increase in pro-apoptotic BH3-only proteins on mitochondria. Furthermore, overexpression of Sab in chemoresistant cells enhanced apoptotic priming and restored cellular vulnerability to a combination treatment of cisplatin and paclitaxel. Contrariwise, inhibiting Sab-mediated signaling or silencing Sab expression in a chemosensitive cell line resulted in decreased apoptotic priming and increased resistance. The effects of silencing on Sab on the resistance to chemotherapeutic agents were emulated by the silencing or inhibition of JNK, which could be attributed to changes in Bcl-2 protein concentrations induced by sub-chronic JNK inhibition. We propose that Sab may be a prognostic biomarker to discern personalized treatments for OC patients.
MKP2 inhibits TGF-β1-induced epithelial-to-mesenchymal transition in renal tubular epithelial cells through a JNK-dependent pathway
Authors: Li Zhenzhen , Liu Xianghua , Tian Fengyan , Li Ji , Wang Qingwei , Gu Chaohui
Published: October 2018

Epithelial-to-mesenchymal transition (EMT) is a phenotypic conversion that plays a crucial role in renal fibrosis leading to chronic renal failure. Mitogen-activated protein kinase phosphatase 2 (MKP2) is a member of the dual-specificity MKPs that regulate the MAP kinase pathway involved in transforming growth factor-β1 (TGF-β1)-induced EMT. However, the function of MKP2 in the regulation of EMT and the underlying mechanisms are still largely unknown. In the present study, we detected the expression of MKP2 in an animal model of renal fibrosis and evaluated the potential role of MKP2 in tubular EMT induced by TGF-β1. We found that the expression of MKP2 was up-regulated in the tubular epithelial of unilateral ureter obstruction rats. Meanwhile, we also demonstrated that TGF-β1 up-regulated MKP2 expression in NRK-52E cells during their EMT phenotype acquisition. Importantly, overexpression of MKP2 inhibited c-Jun amino terminal kinase (JNK) signaling and partially reversed EMT induced by TGF-β1. Moreover, reducing MKP2 expression enhanced JNK phosphorylation, promoted the E-cadherin suppression and induced α-SMA expression and fibronectin secretion in response to TGF-β1, which could be rescued by a JNK inhibitor. These results provide the first evidence that MKP2 is a negative feedback molecule induced by TGF-β1, and MKP2 overexpression inhibits TGF-β1-induced EMT through the JNK signaling pathway. MKP2 could be a promising target to be used in gene therapy for renal fibrosis.
Solving linear equations with messenger-field and conjugate gradient techniques: An application to CMB data analysis
Authors: Papež J. , Grigori L. , Stompor R.
Published: October 2018

We discuss linear system solvers invoking a messenger-field and compare them with (preconditioned) conjugate gradient approaches. We show that the messenger-field techniques correspond to fixed point iterations of an appropriately preconditioned initial system of linear equations. We then argue that a conjugate gradient solver applied to the same preconditioned system, or equivalently a preconditioned conjugate gradient solver using the same preconditioner and applied to the original system, will in general ensure at least a comparable and typically better performance in terms of the number of iterations to convergence and time-to-solution. We illustrate our conclusions with two common examples drawn from the cosmic microwave background (CMB) data analysis: Wiener filtering and map-making. In addition, and contrary to the standard lore in the CMB field, we show that the performance of the preconditioned conjugate gradient solver can depend significantly on the starting vector. This observation seems of particular importance in the cases of map-making of high signal-to-noise ratio sky maps and therefore should be of relevance for the next generation of CMB experiments.
Mergers, tidal interactions, and mass exchange in a population of disc globular clusters
Authors: Khoperskov Sergey , Mastrobuono-Battisti Alessandra , Di Matteo Paola , Haywood Misha
Published: October 2018

We present the results of a self-consistentN-body simulation following the evolution of a primordial population of thick-disc globular clusters (GCs). We study how the internal properties of such clusters evolve under the action of mutual interactions, while they orbit a Milky Way-like galaxy. For the first time, through analytical and numerical considerations, we find that physical encounters between disc GCs are a crucial factor that contributed to the shape of the current properties of the Galactic GC system. Close passages or motion on similar orbits may indeed have a significant impact on the internal structure of clusters, producing multiple gravitationally bound sub-populations through the exchange of mass and even mergers. Our model produces two major mergers and a few small mass exchanges between pairs of GCs. Two of our GCs accrete stars from two companions, ending up with three internal sub-populations. We propose these early interactions and mergers between thick disc GCs with slightly different initial chemical compositions as a possible explanation for the spreads in metallicity observed in some of the massive Milky Ways GCs.

We present an extensive CO emission-line survey of the Planck’s dusty Gravitationally Enhanced subMillimetre Sources, a small set of 11 strongly lensed dusty star-forming galaxies at z = 2–4 discovered with Planck and Herschel satellites, using EMIR on the IRAM 30-m telescope. We detected a total of 45 CO rotational lines from Jup = 3 to Jup = 11, and up to eight transitions per source, allowing a detailed analysis of the gas excitation and interstellar medium conditions within these extremely bright (μLFIR = 0.5 − 3.0 × 1014L⊙), vigorous starbursts. The peak of the CO spectral-line energy distributions (SLEDs) fall between Jup = 4 and Jup = 7 for nine out of 11 sources, in the same range as other lensed and unlensed submillimeter galaxies (SMGs) and the inner regions of local starbursts. We applied radiative transfer models using the large velocity gradient approach to infer the spatially-averaged molecular gas densities, nH2 ≃ 102.6 − 104.1 cm−3, and kinetic temperatures, Tk ≃ 30–1000 K. In five sources, we find evidence of two distinct gas phases with different properties and model their CO SLED with two excitation components. The warm (70–320 K) and dense gas reservoirs in these galaxies are highly excited, while the cooler (15–60 K) and more extended low-excitation components cover a range of gas densities. In two sources, the latter is associated with diffuse Milky Way-like gas phases of density nH2 ≃ 102.4 − 102.8 cm−3, which provides evidence that a significant fraction of the total gas masses of dusty starburst galaxies can be embedded in cool, low-density reservoirs. The delensed masses of the warm star-forming molecular gas range from 0.6to12 × 1010 M⊙. Finally, we show that the CO line luminosity ratios are consistent with those predicted by models of photon-dominated regions (PDRs) and disfavor scenarios of gas clouds irradiated by intense X-ray fields from active galactic nuclei. By combining CO, [C I] and [C II] line diagnostics, we obtain average PDR gas densities significantly higher than in normal star-forming galaxies at low-redshift, as well as far-ultraviolet radiation fields 102–104 times more intense than in the Milky Way. These spatially-averaged conditions are consistent with those in high-redshift SMGs and in a range of low-redshift environments, from the central regions of ultra-luminous infrared galaxies and bluer starbursts to Galactic giant molecular clouds.
Broadening of the differential emission measure by multi-shelled and turbulent loops
Authors: Van Doorsselaere T. , Antolin P. , Karampelas K.
Published: October 2018

Context. Broad differential emission measure (DEM) distributions in the corona are a sign of multi-thermal plasma along the line-of-sight. Traditionally, this is interpreted as evidence of multi-stranded loops. Recently, however, it has been shown that multi-stranded loops are unlikely to exist in the solar corona, because of their instability to transverse perturbations.

Aims. We aim to test if loop models subject to the transverse wave-induced Kelvin-Helmholtz (TWIKH) instability result in broad DEMs, potentially explaining the observations.

Methods. We took simulation snapshots and compute the numerical DEM. Moreover, we performed forward-modelling in the relevant AIA channels before reconstructing the DEM.

Results. We find that turbulent loop models broaden their initial DEM, because of the turbulent mixing. The width of the DEM is determined by the initial temperature contrast with the exterior.

Conclusions. We conclude that impulsively excited loop models have a rather narrow DEM, but that continuously driven models result in broad DEMs that are comparable to the observations.

The propagation of longitudinal stress waves in an infinite rod with a viscoelastic region
Authors: Pashkov Aleksei
Published: October 2018

The problem of propagation of longitudinal stress waves in an infinite piece-wise homogeneous rod with a viscoelastic region of finite size is solved. A mathematical formulation of the problem and its analytical solution in stresses are obtained. The solution uses the method of the Laplace integral transformation with respect to time. The expressions obtained allow one to determine the stresses in an arbitrary cross-section of the rod at any time. The structure of the solution reflects the process of transformation of the incoming wave with its multiple refraction and reflection at the boundaries of the sections. The solution obtained makes it possible to quantitatively investigate the damping effect of the viscoelastic region and can serve as the basis for selecting the parameters of the insert material when it is used to extinguish the dynamic effects.

Published: October 2018

One of the promising areas of processing poultry and livestock waste is anaerobic digestion, which helps to prevent pollution of the natural environment, as well as to receive processing products such as gaseous fuel, biogas and highly effective biofertilizer. The use of plants for the production of biological gas as alternative sources of energy is largely determined by its design characteristics and the worked out technological regimes. The study was conducted with the aim of obtaining data on the effect of the main parameters of the biogas plant and the heat exchanger-agitator on the quality of its operation. This paper considers the thermal processes taking place in the biogas plant in which the mixing device and the heating element are combined into one unit, which allows heating and maintaining the given temperature regime more evenly due to the rotation of the heat exchanger and the transfer of biomass heat throughout the whole volume of the methane. As a result of theoretical studies of the processes of heat exchange and heat transfer taking place in the biogas plant, a mathematical model has been obtained that allows determining the distribution of the temperature of the biomass throughout the entire volume of the methane. It is established that the theoretical temperature homogeneity of the stirred medium is achieved by combining the heat exchanger and the mixing device into one unit, the design and technological parameters of which characterize the intensity of the forced motion of fermentable manure, while changing the value of thermal conductivity.
Method for calculating loads combination on a building using information measures
Authors: Chernetsova Elena , Shishkin Anatoly
Published: October 2018

A method for calculating loads combination on a building is considered using information measures of the connectivity of signals received from sensors of various physical nature, united in a wireless monitoring network. The method includes the definition of the most powerful information measure on the ensemble of process realizations with known a priori load data by the criterion of connectedness of time series. Then, based on the selected information measure, the connectivity of the signals for the ensemble of realizations of the random process of loads to the building from the network formed by the wireless monitoring data bank of time series is calculated. The volume of the data bank sufficient to make the correct decision about the combination of loads on the building with a predetermined error probability is calculated on the basis of a consistent criterion for the ratio of Wald probabilities. This method is easily algorithmized and can be used to develop an automated decision support system.
Bias signal control in differential protection
Authors: Kuprienko Viktor
Published: October 2018

The problem is to ensure the stability of the differential protection functioning at deep saturation of the cores of electromagnetic current transformers. The errors of current transformers support the greatest influence on the operation of differential protections. Features of the differential protection operation at deep saturation of current transformers in short-circuit transient modes are considered. Comparison results of various algorithms for the formation of a bias signal are given. The control capability of the bias signal generation algorithm was analyzed. The harmonic composition of the differential current on the mathematical model of two-arm differential protection in the transient mode with external and internal short circuits at saturation of the current transformers of one arm was investigated. The stability of the differential protection functioning can be enhanced by the selectivity of the bias signal generation algorithm. A bias signal control criterion using a relative level of higher harmonics to a differential signal was proposed.

Published: October 2018

The paper reflects the results of the study of the dependence of factors that form the market value of residential real estate objects at the stages of life cycle on the example of the residential real estate market in the city of Krasnoyarsk. It was determined that the location and lifetime of facilities are the key factors in the formation of the market value of residential property. Based on the conducted economic and statistical analysis, it is proved that the importance of the residential object location can suppress the influence of a high degree of depreciation of the building, thereby increasing the market value of residential property in it. It is justified in the work that the value of a location, being a qualitative characteristic of residential real estate, involves the development of quantitative approaches to its measuring and valuating in order to solve theoretical and methodological problems of management and development of housing construction.

Scientific bases of innovative development of agrarian economic entities: a cluster approach
Authors: Sergey Butorin
Published: October 2018

In the situation of globalization of the world economy, the nature of development of all sectors of the economy, including the agrarian sector, is inextricably linked with active innovation activity. As the foreign and already Russian experience of high-tech sectors of the economy shows, business entities achieve opportunities for innovative development through the involvement of stakeholders (subcontractors, suppliers and consumers) in setting up joint ventures and products, combining economic activities with the goal of more effective joint strategic development. Today, these are agro-clusters, in which both branches of integration of large (including agricultural holdings), and medium and small forms of management are possible, while preserving their legal and economic independence, with legislative and financial support of the state (public-private partnership), should be considered the most promising form of associations of economic entities.

Published: October 2018

Analysis and probation of the optimization model when determining the starting price of the construction contract in the current conditions of economic development. During the research, methods of economic theory, economic statistics and mathematical and statistical tools have been used. The methodical bases of the formation of the initial maximum contract price by dividing it into basic and manageable (controlled) components are considered. The division of the controlled factors into qualitative and quantitative indicators is proposed. The list of the basic expenses by division on the base and conditionally operated components at calculation of the starting price, which essentially differs from the technique of calculation of the estimated cost of the building order, is generated. A methodology for the formation of the contract price for the introduction of innovative investment and construction projects in the system of state procurement has been developed. Based on the research, it follows that, through the controlled factors, it is possible to influence the initial maximum contract price, in particular, by changing qualitative coefficients. As a part of the initial maximum contract price, there are basic and conditionally manageable components that change the contract price without adversely affecting other factors in the implementation of the state construction order. The integral qualitative indicator is a conditional coefficient, which depends on a certain set of qualitative components of the controlled factors, i.e. corresponds to the available set of significant indicators. It is enough to change the value of one of the qualitative indicators, and it will lead to a change in the initial maximum contract price through the integral indicator.
Stimulating the accumulation of deposits in banks to finance the construction industry of the European Union
Authors: Anokhov Igor
Published: October 2018

The paper is devoted to the search for a way of development of the construction industry by the deposits in banks. The analysis of the eurozone statistics has shown that most of the deposits are short-term ones. In addition, loans for the purchase of housing and loans to non-financial corporations are issued mainly for up to one year. This constrains the demand for housing and construction projects, limits the opportunities for long-term crediting construction companies, and also causes Juglar’s economic cycles. In this regard, measures are needed to make the financial plans of all stakeholders on the construction market lengthier. The author proposes to create the targeted deposits in banks under collateral in the form of buildings, structures, and infrastructure facilities. This will increase the propensity to save and invest free money in the construction industry.

Published: October 2018

Socio-economic indicators of the Irkutsk region, Buryatia and the Far East, dynamics of their development in 2016-2017, and problems and prospects are considered in this paper. Today, the priority for the regions of Siberia and the Far East, which possess unique natural resources and a vast territory, is the complex task of increasing the living standard of the population and launching a new economic strategy. The Irkutsk region is one of the largest industrial regions of Russia. The city of Irkutsk was formed as an administrative, commercial and cultural-educational center. Currently, it is home to more than 50% of the urban population of the Irkutsk region. Some enterprises of the city have a machine-building profile. The production of food (more than 45% of the total volume), the construction material, and wood processing also play an important role. External migration has a significant impact on the demographic situation in the region. Most of the migration processes with the crossing of the boundaries of the region take place within Russia. According to statistical data, external migration can be divided as the three main flows of foreign citizens entering the territory of the Irkutsk region: the Central Asian direction (Uzbekistan, Tajikistan, Kyrgyzstan, and Kazakhstan 44.3%); the East Asian direction (China, Mongolia, DPRK, Japan, and Vietnam 30.8%); and the Western direction (Germany, France, and Poland). It should be also noted that 13.9% of all migrants are migrants from Ukraine, Armenia, Belarus, and Moldova, these are mainly young people of working age. The Baikal region is famous in Russia for its natural landscapes: there are more than 1,500 objects of excursion and cognitive significance (natural, architectural, cultural and historical monuments) in the region. The region has a great industrial potential that is of national importance. Several basic complexes and industries compile a modern industrial structure. There are opportunities for further development of the industrial production in the oil and gas industries, diamond mining industry, the production of composite materials, fibers and mineral fertilizers. On the Far East, priority is given today to the raw material economy and the related infrastructure facilities, including the modernization of the Trans-Siberian Railway and the Baikal-Amur Mainline.

On some problems of the legal regime of unauthorized construction objects
Authors: Kudryavtseva Vera , Vasileva Natalia
Published: October 2018

In real socio-economic conditions, unauthorized construction is a phenomenon quite common in contemporary society. Construction remains the main type of land use and planning of the populated areas, especially in the prevailing conditions, when every year the population in large cities of Russia is growing, which leads to a steady expansion of borders and an increase in the area occupied by cities. At the same time, in the absence of a clear, proper urban planning, and the development of urban and rural settlements, the number of buildings being built illegally will increase. In order to prevent the growth of the number of such construction projects, there is a clear legal framework that regulates the concept and consequences of unauthorized actions to create or change real estate objects. When carrying out repairs, modernization, reconstruction, or construction of real estate objects, certain conditions and approvals are required; otherwise, the building can be recognized as unauthorized and become subjected to further liquidation. In order to reduce the practice of unauthorized construction and reduce corruption risks, it is necessary to toughen the interpretation of the concept of unauthorized construction and through the introduction of an unambiguous civil law regulation, especially in the conditions of securing ownership over the objects of such origin.

Municipal property is one of the components of the economic basis of local self-government, and an important factor of the sustainable social and economic development of the city territory. The population feels and evaluates the results of the municipal property management by how its vital needs and interests are satisfied. This is to these needs and interests that municipal property is to serve that indicates its special role and causes the necessity to develop innovative approaches to the system of the municipal property management. Lack of attention of local authorities to this problem is a reason of social conflicts and a deficit of local budgets. Therefore, the management municipal property based on innovative approaches is an urgent task. To solve these issues, the author proposes, firstly, the mechanism for the formation of an innovative approach to the management system of municipal property. Secondly, he suggests a method that allows increasing efficiency of the municipal property management. The proposed mechanisms allow taking into account modern priorities of the municipal development, increasing entrepreneurial activity on the real estate market of municipalities, improving the quality of the municipal authorities’ management, and rationally using the existing municipal property objects.

In recent years, the increasing number of autistic patients has attracted the attention of governments around the world. Normerally, experts will use counseling strategies, drug treatment methods, or the Squeeze Machine, which designed on the basis of the sensory integration theory, to improve those autistic patients’ stereotypical behaviors performance. However, we found the existing machine on sale in the market is too bulky, more expensive and not user-friendly for those autistic students to use. Therefore, we had used expert interviews, practical operations, product analysis and then had performed several design improvements experiments, and had successfully completed the innovative prototype named ‘Sitting Hug Machine’ in an earlier research, and this design has won Taiwan’s invention patent certificate recently. The purpose of this paper is to introduce this new design and verify its enhancement and therapeutic effect. We adapted the model of A-B-A-B reversal of Single-Subject Experimental Design(SSED) with two junior high-school autistic students, and we got a lot of good results, including improvement of stereotypical behaviors performance, more flexible operation, lower machine cost and miniaturization of machine volume, etc. Finally, we hope that the results of this study can be further promoted to benefit more autistic patients and improve their stereotypical behaviors.

The rapid and low-cost manufacturing of continuous Carbon Fiber Reinforced Polymer (CFRP) composites using 3D printing technology is a hot topic in the field of composite materials’ research. Due to the continuity and infusibility of the long carbon fiber, a series of problems such as loosening of fiber, breakage, and nozzle clogging occurred in the printing process, which result in poor surface quality and performance in the printed product. This paper aims to solve these problems based on the researches and optimizations of three-dimensional printing technology for continuous CFRP composite components. Firstly, the coupling mechanism of continuous fiber and resin polymer in the flow path of nozzle is analyzed, the finite element simulation models of flow field and temperature field of CFRP three-dimensional printing are established by using ANSYS CFX software, and the coupling characteristics and interface performance in the printing process are studied. Then, based on the results of simulation analysis, a modification method of the surface coating film is applied, and a special modification solution is configured to modify the surface of the carbon fiber so as to increase its strength and bondability with the molten resin. Finally, the mechanical structure of the three-dimensional printing system of continuous CFRP components is designed to achieve the synchronization of printing and fiber modification. Considering the continuity of continuous carbon fiber, this paper proposed a new method of printing path design called “unicursal” for continuous CFRP parts, that is, when designing and planning a three-dimensional print path, it ensured that there is no interruption in the printing process, so as to achieve carbon fiber continuity in composite parts. The reliability and superiority of the printing system designed in this paper are confirmed by printing of the composite parts.

Membrane technology is widely used in many separation processes because of its multi-disciplinary characteristics. One of the techniques that is used in the fabrication of membranes is the electrospinning process which can create nanofibers from a very wide range of polymeric materials. In this study, electrospun nanostructured fibrous composite membranes of polysulfone (PSU), commercial halloysite (COM-HAL), and Philippine halloysite (PH-HAL) were synthesized. The concentrations of COM-HAL and PH-HAL were both varied from 0.5%, 1%, and 2%. The FTIR results showed that there were changes in the intensity of the PSU-IR spectra which confirmed the presence of COM-HAL and PH-HAL in the synthesized membranes. The SEM revealed that nanofibers can be successfully produced by the addition of LiCl salt in PSU with varying HAL concentrations. Also, it was observed that the addition of HAL with varying concentrations have no significant effect on wettability due to the strong hydrophobic character of the PSU membrane. Moreover, it was found from the analysis of mechanical properties that the tensile strength of the membranes weakened by the addition of HAL due to its weak interaction with PSU.

The cross-entropy criterion of mainstream neural network training is to classify and optimize each frame of acoustic data, while the continuous speech recognition uses the sequence-level transcription accuracy as a performance measure. In view of this difference, an end-to-end speech recognition system based on sequence level transcription is constructed in this paper. The model uses convolution neural network to deal with the input features, selects the best network structure, and performs two-dimensional convolution in the time and frequency domains. At the same time, neural network uses batch normalization technology to reduce generalization error and speed up training. Finally, the hyper-parameters in decoding process are optimized to improve the modelling effect. Experimental results show that the system performance is improved a lot, better than mainstream speech recognition systems.

In the process of air combat implementation, the real-time command and guidance of air pilot is the key element of air combat irreplaceable. In this paper, a multi-aircraft air combat command and guidance target allocation model is established based on the actual air combat situation. The unbalanced target allocation problem of multi-aircraft air combat command and guidance is studied by combining Hungarian algorithm and evolutionary Hungarian algorithm. Finally, two cases of increasing aircraft number and decreasing aircraft number are simulated and studied. Simulation results show that the method can shorten the computation time and ensure the overall command and guidance advantages of the target allocation scheme effectively.
