A measurement is reported of differential top quark pair (tt¯) production cross sections, where top quarks are produced at large transverse momenta. The data collected with the CMS detector at the LHC are from pp collisions at a center-of-mass energy of 13 TeV corresponding to an integrated luminosity of 35.9 fb−1. The measurement uses events where at least one top quark decays as t→Wb→qq¯′b and is reconstructed as a large-radius jet with transverse momentum in excess of 400 GeV. The second top quark is required to decay either in a similar way or leptonically, as inferred from a reconstructed electron or muon, a bottom quark jet, and missing transverse momentum due to the undetected neutrino. The cross section is extracted as a function of kinematic variables of individual top quarks or of the tt¯ system. The results are presented at the particle level, within a region of phase space close to that of the experimental acceptance, and at the parton level and are compared to various theoretical models. In both decay channels, the observed absolute cross sections are significantly lower than the predictions from theory, while the normalized differential measurements are well described.

Constructing Edge-Colored Graph for Heterogeneous Networks

Journal of Computer Science & Technology 2015年第5期30卷 1154-1160页

作者：侯睿武继刚陈亚文张海波隋秀峰 School of Computer Science and Software Engineering Tianjin Polytechnic University Tianjin 300387 China State Key Laboratory of Computer Architecture~ Institute of Computing Technology Chinese Academy of Sciences Beijing 100190 China Department of Computer Science University of Otago Dunedin 9054 New Zealand

In order to build a fault-tolerant network, heterogeneous facilities are arranged in the network to prevent homogeneous faults from causing serious damage. This paper uses edge-colored graph to investigate the features of a network topology which is survivable after a set of homogeneous devices malfunction. We propose an approach to designing such networks under arbitrary parameters. We also show that the proposed approach can be used to optimize inter-router connections in network-on-chip to reduce the additional consum!otion of energy and time delay.

Ltd Tokyo Japan

From the perspectives of comfort and reduced energy use, the capture efficiency of a hood is a crucial index to determine the required ventilation (air flow-rate) for a commercial kitchen. For this reason, more precise measurement of capture efficiency is required. Conventionally, its measurement is done in a laboratory with a high ceiling. In this study, a method is proposed to measure capture efficiency in a laboratory of normal ceiling height, and to verify the validity of the method. The basic measurement technique is to minimize the influence of recapture by appropriately adjusting the ceiling-exhaust air flow. At times, the influence on recapture by ceiling exhaust cannot be completely eliminated. In this case, estimating the background concentration affecting recapture, using the Extrapolation of Tracer gas concentration Decay (ETD) method (based on concentration decay after the tracer gas supply stops), is used to calculate the capture efficiency. In addition, in this study, measurements in a laboratory with a high ceiling were compared with those in a laboratory with a ceiling of normal height. This confirmed that the capture efficiency modified by the ETD method, matches the other. © 2015 International Society of Indoor Air Quality and Climate. All Rights Reserved.

The study presented here provides a framework for studying the performance of plant wall system of different scales and installations adapted to a range of building zonal air volumes. The formaldehyde removal capacity of a combination of three porous materials (growstone, expanded clay and activated carbon) loaded in an architectural module was evaluated under several conditions. Seven airflow rates (9, 18, 27, 36, 54, 63 and 72 l/min) and four concentration levels (2.00 g/m3, 0.73 g/m3, 0.37 g/m3 and 0.19 g/m3) were studied using a single module of a plant wall system. The single pass removal efficiency was evaluated over an 8-h period for seventeen different cases. In all cases, the slowest airflow rate showed the highest single pass removal efficiency. From the results of these experiments, the relative number and sizing of plant wall modules required for selected building types to remove toxins from indoor environments was further assessed. © 2015 International Society of Indoor Air Quality and Climate.

Angular correlations between heavy-flavor decay electrons and charged particles at midrapidity (|η|<0.8) are measured in p-Pb collisions at sNN=5.02 TeV. The analysis is carried out for the 0%–20% (high) and 60%–100% (low) multiplicity ranges. The jet contribution in the correlation distribution from high-multiplicity events is removed by subtracting the distribution from low-multiplicity events. An azimuthal modulation remains after removing the jet contribution, similar to previous observations in two-particle angular correlation measurements for light-flavor hadrons. A Fourier decomposition of the modulation results in a positive second-order coefficient (v2) for heavy-flavor decay electrons in the transverse momentum interval 1.5

Ukraine is the largest consumer of hydrocarbons per unit of production in Europe (Ukraine policy review, 2006). The most important point is a reduction of energy consumption in chemical and metallurgical industries as a biggest consumer. This paper deals with energy savings potential of light hydrocarbons separation process. Energy consumption of light hydrocarbons separation process processes typical of Eastern European countries were analysed. Process Integration (PI) was used to perform a preliminary analysis of different units and fulfil the retrofit project of Total Site Integration (TSI). A new heat exchanger network (HEN) were developed and the equipment was calculated with use of the Pinch principles. A complex method was developed and applied to integrate several units at the enterprise site demonstrating the possibility to use heat pumps. Heat pump integration increases heat recovery and offers a solution in order to increase energy savings and project profitability. The heat transfer area and number of heat exchangers for a retrofitted heat exchanger network have been identified. The estimated payback period for integration Heat Pump of Gas Separation Enterprise is about 127 days and the pathways of plant modernization have been also proposed.

This paper presents a study on the behaviour of the walls of the Rocca Roveresca of Senigallia in Italy built in the XIV century on the ruins of a former Roman defensive structure. This is a peculiar example of a small fortress that had undergone in the XV century important modifications of the plant in order to enhance its defensive performances. A linear finite element model is first developed in order to understand the dynamic behaviour of a generic portion of the wall and to detect the probable incipient failure mechanisms. A subsequent static nonlinear analysis is carried out, with the same finite element model, to investigate the formation of the cracking layout and to detect the position of plastic hinges. The last analysis level is carried out with a tailored macro-element constituted by three bodies, namely the two external curtains and the inner fill for which a degradation of the behaviour is considered. The results obtained demonstrates the efficiency of the wall against earthquakes characterized by return times typical for ultimate limit states. Same issues that deserve further investigation are highlighted.

This paper presents an experimental study, which includes the oedometer test and isotropic creep test, on the compressibility and the creep effect of the plasticine materials. The Compression Index (CcΕ), Rebounding Index (CrΕ) and creep coefficient (CαΕ) are obtained from the test results. However, it can be observed that there is almost no loop in unloading-reloading stages of stress-strain relationship, which is different from most soil test results. By means of the Scanning Electron Microscope, it could be found that the compression of the plasticine is mainly due to the porosity decrease and the structure flocculence, which is nonrecoverable. © Springer International Publishing Switzerland 2015.
