摘要：
ALICE (A Large Ion Collider Experiment) is the LHC (Large Hadron Collider) experiment devoted to investigating the strongly interacting matter created in nucleus-nucleus collisions at the LHC energies. The ALICE ITS, Inner Tracking System, consists of six cylindrical layers of silicon detectors with three different technologies; in the outward direction: two layers of pixel detectors, two layers each of drift, and strip detectors. The number of parameters to be determined in the spatial alignment of the 2198 sensor modules of the ITS is about 13,000. The target alignment precision is well below 10 mu m in some cases (pixels). The sources of alignment information include survey measurements, and the reconstructed tracks from cosmic rays and from proton-proton collisions. The main track-based alignment method uses the Millepede global approach. An iterative local method was developed and used as well. We present the results obtained for the ITS alignment using about 10(5) charged tracks from cosmic rays that have been collected during summer 2008, with the ALICE solenoidal magnet switched off.

摘要：
Fabrication of ZnO/graphene hybrid by homogeneous depositing a continuous and conformable ZnO layer on graphene remains a great challenge and highly desired. In this paper, well-defined flake-like ZnO/graphene hybrid was fabricated by a facile in situ hydrolysis-deposition route using zinc acetate and graphene oxide (GO) as starting materials and ammonia as precipitator and reductant. By rational control the hydrolysis and condensation of Zn precursor, ZnO nanocrystals are homogeneously anchored on graphene due to the strong interaction between ZnO and GO, which was simultaneously reduced to graphene. The photocatalytic activity of the photocatalyst was evaluated using Brilliant Red X-3B (X3B) dye as probe. It was found that the presence of GO enhanced the crystallization of ZnO, and the photocatalytic activity of ZnO/graphene hybrid increases first and then decreases with increasing the amount GO. The hybrid with 3 wt.% of GO shows the highest photocatalytic activity, which is 3 times higher than that of pure ZnO. (C) 2015 Elsevier B.V. All rights reserved.

摘要：
Two triazole-modified calix[4]arene diesters were synthesized via Huisgen 1,3-dipolar cycloaddition between azides esters and alkynylcalixarenes. Their structures had been deduced from (1)H NMR, element analysis and ESI-MS. Two-phase extraction experiments indicated that triazole-modified calix[4]arene diethylester 3a exhibited Cs(+) selectivity.

摘要：
Beam energy scan programs in heavy-ion collisions aim to explore the QCD phase structure at high baryon density. Sensitive observables are applied to probe the signatures of the QCD phase transition and critical point in heavy-ion collisions at RHIC and SPS. Intriguing structures, such as dip, peak and oscillation, have been observed in the energy dependence of various observables. In this paper, an overview is given and corresponding physics implications will be discussed for the experimental highlights from the beam energy scan programs at the STAR, PHENIX and NA61/SHINE experiments. Furthermore, the beam energy scan phase II at RHIC (2019-2020) and other future experimental facilities for studying the physics at low energies will be also discussed.

摘要：
The phase diagrams of four binary systems (C10H21NH3)2CoCl4−(C16H33NH3)2CoCl4, (C12H25NH3)2CoCl4−(C16H33NH3)2CoCl4, (C10H21NH3)2ZnCl4−(C16H33NH3)2ZnCl4 and (C12H25NH3)2ZnCl4−(C16H33NH3)2ZnCl4 were investigated by means of DSC. These six compounds and their binary mixtures can retain energies between 74 and 115 J/g during solid-state transformations at temperatures between 70 and 105°C, and they are therefore being considered for potential use in solar energy systems.;Mittels DSC wurden die Phasendiagramme der vier binären Systeme (C10H21NH3)2CoCl4−(C16H33NH3)2CoCl4, (C12H25NH3)2CoCl4−(C16H33NH3)2CoCl4, (C10H21NH3)2ZnCl4−(C16H33NH3)2ZnCl4 und (C12H25NH3)2ZnCl4−(C16H33NH3)2ZnCl4 untersucht. Diese sechs Verbindungen und ihre binären Gemische können bei Feststoffumwandlungen zwischen 70 und 105°C Energien zwischen 74 und 115 J/g zurückhalten und wereden deshalb für einen potentiellen Einsatz als Sonnenenergiesysteme in Betracht gezogen.

摘要：
Collective flow reflects the dynamical evolution in high-energy heavy ion collisions. In particular, the elliptic flow reflects early collision dynamics [1]. We present a systematic analysis of elliptic flow (v(2)) for identified particles measured in Au + Au and Cu + Cu collisions at root s(NN) = 200 GeV. Number of quark scaling is tested in the intermediate p(T) region and in the smaller system (Cu + Cu). The Cu + Cu collisions results are compared with those from ideal hydrodynamic model calculations.

摘要：
Herein, a series of Ga-doped CdS photocatalysts are successfully prepared by simple solvothermal method using absolute ethyl alcohol as only reaction solvent. The samples have been characterized by X-ray diffraction, scanning electron microscope, UV-vis diffuse reflectance spectrum, X-ray photoelectron spectroscopy and electrochemical measurements. Their photocatalytic activity has been evaluated by the photocatalytic degradation of rhodamine B (RhB) under simulated visible-light irradiation. It is found that the prepared samples are interstitial Ga-doped CdS, which has never been reported before. The photocatalytic activity of Ga-doped CdS with molar ratio of Ga:Cd = 1:50 for RhB degradation can be enhanced by 114% in comparison with that of pure CdS under same reaction conditions. All of the data based on theoretical calculation and experiment indicate that Ga ion doped into the interstice of crystal lattice in CdS can not only lower the valence band position but also decrease the formation energy of the CdS samples. What is more, Ga ion doping can widen the valence band of CdS semiconductor, which is quite beneficial for the separation of photo-generated carriers. As a result, the Ga-doped CdS not only has improved photocatalytic activity for the degradation of pollutant pollutants but also has enhanced stability under visible-light irradiation. In a word, Ga-doped CdS will be a promising photocatalyst with richly potential application prospect under solar light. (C) 2013 Elsevier B.V. All rights reserved.

摘要：
A sensitive anodic stripping procedure for trace nitrite in the presence of added cetyltrimethylammonium bromide (CTMAB) is described. The method is based on the electrodeposition and subsequent oxidation of CTMAB-nitrite complex on a glassy carbon electrode in a supporting solution, consisting of Britten-Robinson buffer solution, pH range 3.6-4.0, and CTMAB. The peak height is proportional to the concentration of nitrite over the range 0.01-0.25 mu g ml(-1), and the relative standard deviation is less than 3.3%. This method has been used for the determination of trace nitrite in water and meat products with 90-110% recovery. (C) 1997 Elsevier Science Ltd.

摘要：
We report selected results from a recent in-depth study of jet shapes and jet cross sections in ultra-relativistic reactions with heavy nuclei at the LHC. We demonstrate that at the highest collider energies these observables become feasible as a new, differential and accurate test of the underlying QCD theory. Our approach allows for detailed simulations of the experimental acceptance/cuts that help isolate jets emerging from a dense QGP. We show for the first time that the pattern of stimulated gluon emission can be correlated with a variable quenching of the jet rates and provide an approximately model-independent approach to determining the characteristics of the medium-induced bremsstrahlung spectrum. The connection between such cross section attenuation and the in-medium jet shapes is elucidated.

摘要：
The financial market volatility forecasting is regarded as a challenging task because of irregularity, high fluctuation, and noise. In this study, a multiscale ensemble forecasting model is proposed. The original financial series are decomposed firstly different scale components (i.e., approximation and details) using the maximum overlap discrete wavelet transform (MODWT). The approximation is predicted by a hybrid forecasting model that combines autoregressive integrated moving average (ARIMA) with feedforward neural network (FNN). ARIMA model is used to generate a linear forecast, and then FNN is developed as a tool for nonlinear pattern recognition to correct the estimation error in ARIMA forecast. Moreover, details are predicted by Elman neural networks. Three weekly exchange rates data are collected to establish and validate the forecasting model. Empirical results demonstrate consistent better performance of the proposed approach.
