Authors: Yan Hongwei , Hong Yuxiao , Cai Yunfei
Published: December 2019

Objectives: FAS plays a critical role in the extrinsic apoptosis pathway in autoimmune diseases. Previous studies investigating the association between FAS gene −670 A/G and −1377 G/A polymorphisms and the risk of autoimmune diseases reported controversial results. We performed the meta-analysis to evaluate the possible association. Methods: Relevant studies were identified by searching the PubMed, Embase, CNKI, and Wanfang databases up to December 2018. Odds ratios (ORs) and corresponding 95% confidence intervals (CIs) were calculated to determine the association. Results: A total of 43 articles including 67 studies (52 studies for FAS −670 A/G and 15 studies for −1377 G/A) were included in the meta-analysis. Our meta-analysis showed that the FAS −670 A/G polymorphism was associated with the risk of autoimmune diseases (GG vs. GA: OR = 1.079, 95% CI = 1.004–1.160, P=0.038), especially in Caucasians (GG vs. GA: OR = 1.12, 95% CI = 1.03–1.23, P=0.012), Asians (G vs. A: OR = 0.89, 95% CI = 0.83–0.96, P=0.002), systemic lupus erythematosus (SLE) (G vs. A: OR = 0.85, 95% CI = 0.77–0.94, P=0.001), multiple sclerosis (MS) (GG+GA vs. AA: OR = 0.83, 95% CI = 0.70–0.99, P=0.043), systemic sclerosis (SSc) (GG vs. GA: OR = 1.20, 95% CI = 1.07–1.36, P=0.003) and Hashimoto’s thyroiditis (HT) (G vs. A: OR = 1.45, 95% CI = 1.10–1.90, P=0.008); the FAS −1377 G/A polymorphism was associated with the risk of autoimmune diseases (A vs. G: OR = 1.11, 95% CI = 1.03–1.20, P=0.008), especially in Asians (A vs. G: OR = 1.15, 95% CI = 1.05–1.25, P=0.002) and high quality studies (A vs. G: OR = 1.14, 95% CI = 1.05–1.24, P=0.002). Conclusion: This meta-analysis demonstrated that the FAS –670A/G and –1377 G/A polymorphisms were associated with the risk of autoimmune diseases.
Individual Differences in Distributional Learning for Speech: What's Ideal for Ideal Observers?
Authors: Theodore Rachel M. , Monto Nicholas R. , Graham Stephen
Published: December 2019

Purpose

Speech perception is facilitated by listeners' ability to dynamically modify the mapping to speech sounds given systematic variation in speech input. For example, the degree to which listeners show categorical perception of speech input changes as a function of distributional variability in the input, with perception becoming less categorical as the input, becomes more variable. Here, we test the hypothesis that higher level receptive language ability is linked to the ability to adapt to low-level distributional cues in speech input.

Method

Listeners (
n
= 58) completed a distributional learning task consisting of 2 blocks of phonetic categorization for words beginning with /g/ and /k/. In 1 block, the distributions of voice onset time values specifying /g/ and /k/ had narrow variances (i.e., minimal variability). In the other block, the distributions of voice onset times specifying /g/ and /k/ had wider variances (i.e., increased variability). In addition, all listeners completed an assessment battery for receptive language, nonverbal intelligence, and reading fluency.

Results

As predicted by an ideal observer computational framework, the participants in aggregate showed identification responses that were more categorical for consistent compared to inconsistent input, indicative of distributional learning. However, the magnitude of learning across participants showed wide individual variability, which was predicted by receptive language ability but not by nonverbal intelligence or by reading fluency.

Conclusion

The results suggest that individual differences in distributional learning for speech are linked, at least in part, to receptive language ability, reflecting a decreased ability among those with weaker receptive language to capitalize on consistent input distributions.
Experimental and numerical studies of sound generated by cavities

Published: December 2019

Cavities and gaps are an important element in the construction of many devices and machines, including energy sector applications. This type of flow is usually coupled with strong pressure fluctuations inside the cavity, which are emitted into the far field in the form of a sound wave responsible for the noise generation. This applies to both subsonic and supersonic flows. Pressure fluctuations often have the character of single tones of a specific frequency and high amplitude and their generation is associated with a vortex shedding formed directly above the inlet and its interaction with the walls of the cavity. The presented work include description of developed test stand and applied measurement techniques dedicated to the analysis of high frequency phenomena. In addition, the adopted numerical model will be described, including conducted two-dimensional and three-dimensional analysis. The developed models will be validated based on experimental measurements concerning wide range of flow conditions.

Authors: Motylinski Konrad , Wierzbicki Michał , Jagielski Stanisław , Kupecki Jakub
Published: December 2019

One of the key issues in the energy production sector worldwide is the efficient way to storage energy. Currently- more and more attention is focused on Power-to-Gas (P2G) installations- where excess electric power from the grid or various renewable energy sources is used to produce different kind of fuels- such as hydrogen. In such cases- generated fuels are treated as energy carriers which- in contrast to electricity- can be easy stored and transported. Currently- high temperature electrolysers- based solid oxide cells (SOC)- are treated as an interesting alternative for P2G systems. Solid oxide electrolysers (SOE) are characterized as highly efficient (~90%) and long-term stable technologies- which can be coupled with stationary power plants. In the current work- the solid oxide cell stack was operated in electrolysis mode in the endothermic conditions. Based on the gathered experimental data- the numerical model of the SOC stack was created and validated. The prepared and calibrated model was used for generation of stack performance maps for different operating conditions. The results allowed to determine optimal working conditions for the tested stack in the electrolysis mode- thus reducing potential costs of expensive experimental analysis and test campaigns.

These differences are mainly related to the characteristics of its ashes (quantity and composition) which increase certain problematic phenomena during combustion, among them ash sintering. The main purpose of this article is the experimental study of these issues for various agro pellets and wood pellets, analyzed in various operating conditions in a laboratory reactor with a circulating bed.
Experimental investigation of LWR passive safety systems performance at the INKA test facility
Authors: Bryk Rafał , Mull Thomas , Schmidt Holger
Published: December 2019

INKA is a test facility designed by Framatome and built in the technical center in Karlstein. The original objective for establishing this test rig was the investigation of the performance of the passive safety systems developed in a new Framatome Boiling Water Reactor (BWR) design – KERENA. INKA was constructed in the scale of 1:1 in heights while the total volume of the containment was replicated in 1:24. Since the geometries of particular safety systems are faithfully reflected, their actual performance in the original plant can be investigated at the full scale. Due to the unquestionable interest of the nuclear community in the inherent safety, not only new BWR and PWR designs are equipped with the passive systems, but also particular passive solutions are considered to be applied into the already existing Light Water Reactors (LWR). In this context and due to the fact that both, single component tests and integral tests can be conducted at INKA, the facility can be employed for a demonstration/qualification of a large range of passive safety systems foreseen for quite different types of LWRs. Hence, the goal of the EASY project was the experimental confirmation of the passive systems performance and the analysis of their interactions between each other in the integral tests. Besides, the overarching target of all tests performed at INKA is provision of data for codes validation. This paper presents major outcomes and conclusions drawn on the basis of EASY project results.

The innovative use of the Fuel-Water emulsion in a small gas turbine for distributed energy generation is proposed. The FWE in this situation is considered as a nonhomogeneous mix of water and fuel, where water is a dispersed phase in the continuous fuel phase with an addition of surfactants. The Fuel-Water emulsion has a great mainly due to two mechanisms: temperature reduction due to heat absorption by the water phase and enhanced homogeneity of the fuel-air mixture due to micro-explosion of the superheated water phase inside the emulsion droplet. Proposed paper presents theoretical background on Fuel-Water emulsion combustion mechanism. Finally initial results of numerical research of fuel-water emulsion injection to miniature gas turbine are presented. Theoretical predictions of NOX pollutant emissions are compared with accuracy of the gas analyzer planned to be used during experimental research.

Authors: Zarzycki Robert , Jędras Justyna , Kobyłecki Rafał
Published: December 2019

This study presents the concept of a cyclone furnace for coal dust combustion and gasification under conditions of oxy-fuel combustion. A two-chamber design of the cyclone furnace allows for the separation of the process of heating, drying and devolatilization of fuel from processes of its combustion and gasification of carbon residue. The choice of process parameters helps control fuel gasification. Supplying the driving gas with a specific composition (O2, CO2) to the chamber PC1 ensures the control of temperature and composition of combustible gases obtained through gasification. These gases can be used as a fuel for power boilers and, consequently, allow for utilization of the oxy-fuel combustion technology in new or existing power boilers.

Published: December 2019

The numerical simulation analysis of the two groups of fullscale complex tubular joints of the Beijing New Airport Terminal C type steel column under space static loading tests has been conducted by adopting software ABAQUS. The results obtained from the numerical simulation analysis consistent with those from the tests which enriched the research findings. Based on the research, mechanical performance of the joints has been carried out, the failure modes and ultimate bearing capacity of the joints with no stiffening ribs, three stiffening ribs and five stiffening ribs has been obtained. The numerical simulation results showed that, the bearing capacity of the joints without stiffening ribs were relatively low, the plastic failure of the main pipe was the major form of the destruction and the safety performance were too poor to meet the actual needs of the project. The bearing capacity of the joints significantly improved with the stiffening ribs set inside and the destruction changed to the connection of the main tubular and the branch, which means that the stress of the joints has been obviously improved by the setting of the stiffening ribs and was able to meet the needs of Beijing New Airport Terminal C type column. Through the comparative analysis of the stiffening ribs setting, it can be found that the bearing capacity of the joints were similar between the three and five stiffening ribs, considering the construction difficulty and economic benefits, three stiffening ribs has been selected as the final optimization result.

Published: December 2019

Defining the geometrics and structure of linear and strip composite urban green belts of aesthetic and environment-protection functions intended for transportation infrastructure facilities in urban planning zones and historic centers in densely built-up areas intensely used by transportation services. The observations were made in streets of major cities and on physical models of buildings and green belts of three degrees of density, from dense to permeable. The dependence of air-pollutant shielding efficiency of green belts on their density and height has been determined. Vertical concentration fields on the street cross-section have been obtained by physical modeling, and consistent patterns of car emissions dispersion by shelterbelts of various structure have been found. The lowest car emissions concentration behind green belts is observed at a distance equaling h (belt height) to 1,5 h, where the pedestrians move; the highest, at a distance of 2 h to 3 h. To effectively protect the pedestrian ways and the areas along the road from car emissions, dense and evenly semi-open shelterbelts, 15 to 30 m wide should be used. If the width of the road dividing strip is limited, shelterbelts with the openness factor of 0,5 to 0,6 should be used. The plant rows closest to the road should consist of shrubbery making a two-storey hedge, and of low-crown trees, with the further rows increasing in height.

The role of elements of the Economics of Quality in mathematical modelling of socio-economic processes
Authors: Okrepilov Vladimir , Chetyrkina Natalia , Krylov Mikhail
Published: December 2019

Nowadays, when making managerial decisions, specialists are faced with the need to process ever-increasing volumes of information in an increasingly shorter time. The need for the development of a methodology for social forecasting on the basis of detailed development models is growing. Since the basis of the activity of the socio-economic system of any level is an anthropogenic factor, this increases the degree of probability of the implementation of various scenarios. To develop more accurate forecasts, it is necessary to use the tools of the economics of quality standardization, metrology, quality management. Standardization determines the ability to normalize and assess sustainability indicators of development, as well as management methods. Metrology provides uniform methods for measuring these indicators. Based on the received information, quality management systems allow making reliable managerial decisions. The use of tools of the economics of quality is possible at almost all stages of socio-economic modelling. The role of elements of the economics of quality, in particular standardization, is especially growing in the development of the digital economy and “smart cities”, where a complete unification of the formats for accumulating and transmitting information to all users is required.

Authors: Chemborisova Nailya
Published: December 2019

The operating reliability of electrical power systems is mostly based on the topology and parameters of the schemes considered in this article. The preliminary (before the calculation of operating conditions) analysis of the rigidity or sensitivity of nodes, based on the matrix of node conductivity, allows for evaluating and increasing the controllability of conditions by voltages and limiting short-circuit currents, making the reduction of active power losses in the grid more efficient. A conclusion was made regarding the consistent effects of changes in the node rigidity on increasing the EPS operating reliability.
Risks in the energy sector: management practices analysis in the electricity market
Authors: Zhilkina Yulia
Published: December 2019

Energy security is today one of the most discussed event in international economic relations. It is being actively discussed by all governments and leading international organizations. There doesn’t exist any universal definition of energy sector. In addition to the lack of such a universal definition, analysis of decisions in this area, one notices the lack of attention to such phenomena as risks in the energy sector, especially in the management of investment projects in the industry. For most industrial countries, energy insecurity means import dependency and aging infrastructure, while many emerging economies have additional vulnerabilities such as insufficient capacity, high energy intensity, and rapid demand growth. In many low-income countries, multiple vulnerabilities overlap, making them especially insecure.

It is very difficult to find any area of the state economy where metals and, in particular, steel are not required. The range of varieties has become enormous, and accordingly, the task of saving energy, fuel and resources for its manufacture becomes extremely urgent. Below in this context, we consider the procedures for the production of alloy steels, when each alloying additive has its own individual price, and the steel scheme is a narrowly specialized purpose.

La société est confrontée à des problèmes inédits et globaux. Les sciences sont sollicitées pour éclairer les citoyens et trouver des solutions durables mais restent désarmées face au caractère transversal des problématiques. Ces dernières concernent l’ensemble de la société, en particulier les organisations de la société civile à but non lucratif qui expérimentent des solutions et pour qui l’accès aux moyens de recherche se pose. Le développement d’interfaces sciences-société apparaît intéressant à l’instar de la Boutique des sciences créée dans la région des Hauts-de-France. Sans occulter les difficultés de sa mise en œuvre, cet article montre comment s’est constitué cet outil en procédant en deux temps : une enquête sociologique auprès des acteurs chercheurs, étudiants et représentants des organisations de la société civile, suivie d’une élaboration par un processus de cocréation les associant.

Enhancement of ultrafast nonlinear optical response of zinc selenide nanoparticle decorated reduced graphene oxide sheets
Authors: Rahaman Abdulla Bin , Bhattacharya Sayantan , Sarkar Atri , Singha Tara , Banerjee Debamalya , Datta Prasanta K.
Published: December 2019

The synergistic effect of zinc selenide (ZnSe) nanoparticle functionalized into reduced graphene oxide (RGO) sheets on nonlinear optical (NLO) properties has been investigated by single beam z-scan technique. Comprehensive measurements on nonlinear absorption (NLA) as well as nonlinear refraction (NLR) have been performed on RGO, ZnSe, and RGO-ZnSe composites at 630 nm in the femtosecond regime. Both NLA and NLR of RGO-ZnSe show an enhancement in NLO properties compared to pure RGO and ZnSe in an intensity range of 37GW/cm2 to 130GW/cm2. The enhanced optical nonlinearity of RGO-ZnSe may have been caused due to strong interlayer coupling between RGO and ZnSe, as well as the availability of a large number of NLA states in the composite. The interlayer coupling between ZnSe nanoparticles and RGO sheets has been confirmed by transmission electron microscopy, UV-Visible, and photoluminescence spectroscopy. At low input pulse intensity (∼37GW/cm2), saturation absorption dominates, whereas NLA becomes prominent in the higher intensity regime (55GW/cm2–130GW/cm2) for RGO and ZnSe. NLA is the dominant phenomenon for RGO-ZnSe in the whole experimental intensity range. Moreover, it is observed that the dispersion of RGO, ZnSe, and RGO-ZnSe in dimethylformamide exhibits positive NLR. This study indicates an enhancement in nonlinear optical response of the RGO-semiconductor composite, which is very promising for graphene based photonic device applications.
Design of experimental setup for liquid nitrogen assisted polycrystalline diamond compact bit drilling

Published: December 2019

A liquid nitrogen assisted polycrystalline diamond compact (PDC) bit drilling method is expected to be suitable for hot dry rock (HDR) drilling because the huge thermal stress induced in the drilling process can help to break the rock and the low temperature liquid nitrogen can efficiently cool the drilling tools. However, there is no experimental research on liquid nitrogen assisted PDC bits breaking high temperature granite, and the rock breaking efficiency of this new drilling method is still unclear. To investigate the feasibility and efficiency of liquid nitrogen assisted PDC bit breaking HDR, a novel experimental setup was designed. This setup is composed of four units: the drilling fluid circulation system, drilling system, formation simulation system, and data acquisition and control system. It can also be used to research the effects of drilling parameters such as weight on bit, rotary speed, drilling fluid jet pressure, and feed speed on drilling efficiency. A series of drilling experiments using liquid nitrogen and water have been successfully carried out with this setup. The results indicate that liquid nitrogen assisted PDC bit drilling has excellent performance in breaking HDR, which can accelerate the application of this new technique in geothermal drilling.
Witnessing incompatibility of quantum channels
Authors: Carmeli Claudio , Heinosaari Teiko , Miyadera Takayuki , Toigo Alessandro
Published: December 2019

We introduce the notion of incompatibility witness for quantum channels, defined as an affine functional that is non-negative on all pairs of compatible channels and strictly negative on some incompatible pair. This notion extends the recent definition of incompatibility witnesses for quantum measurements. We utilize the general framework of channels acting on arbitrary finite-dimensional von Neumann algebras, thus allowing us to investigate incompatibility witnesses on measurement-measurement, measurement-channel, and channel-channel pairs. We prove that any incompatibility witness can be implemented as a state discrimination task in which some intermediate classical information is obtained before completing the task. This implies that any incompatible pair of channels gives an advantage over compatible pairs in some such state discrimination task.
