摘要:
A measurement of dijet correlations in p-Pb collisions at root s(NN) = 5.02 TeV with the ALICE detector is presented. Jets are reconstructed from charged particles measured in the central tracking detectors and neutral energy deposited in the electromagnetic calorimeter. The transverse momentum of the full jet (clustered from charged and neutral constituents) and charged jet (clustered from charged particles only) is corrected event-by-event for the contribution of the underlying event, while corrections for underlying event fluctuations and finite detector resolution are applied on an inclusive basis. A projection of the dijet transverse momentum, k(Ty) = p(T,jet)(ch+ne) sin(Delta phi(dijet)) with Delta phi(dijet) the azimuthal angle between a full and charged jet and p(T,jet)(ch+ne) the transverse momentum of the full jet, is used to study nuclear matter effects in p-Pb collisions. This observable is sensitive to the acoplanarity of dijet production and its potential modificationin p-Pb collisions with respect to pp collisions. Measurements of the dijet k(Ty) as a function of the transverse momentum of the full and recoil charged jet, and the event multiplicity are presented. No significant modification of k(Ty) due to nuclear matter effects in p-Pb collisions with respect to the event multiplicity or a PYTHIA8 reference is observed.

摘要:
Manganese dioxide (MnO<inf>2</inf>) and CuBi<inf>2</inf>O<inf>4</inf>-doped MnO<inf>2</inf> thin films with different nanostructures were deposited on indium tin oxide (ITO) glass and Ti foil substrates by using a chemical bath deposition (CBD) technique. The samples were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM) and X-ray photoelectron microscopy (XPS). The effects of doping and substrates on electrochemical properties of MnO<inf>2</inf>and CuBi<inf>2</inf>O<inf>4</inf>-doped MnO<inf>2</inf> thin films on ITO glass and Ti foil were investigated. Capacitive properties of MnO<inf>2</inf> and CuBi<inf>2</inf>O<inf>4</inf>-doped MnO<inf>2</inf> thin films electrodes were studied using cyclic voltammetry and electrochemical impedance spectroscopy in a three-electrode experimental setup using 0.1 M Na<inf>2</inf>SO<inf>4</inf> aqueous solution as electrolyte. Specific capacitance, obtained from electrochemical measurement for the CuBi<inf>2</inf>O<inf>4</inf>-doped MnO<inf>2</inf>, exhibited a higher value of 338 F g<sup>-1</sup> compared to the MnO<inf>2</inf> exhibiting value of 135 F g<sup>-1</sup>. In addition, CuBi<inf>2</inf>O<inf>4</inf>-doped MnO<inf>2</inf> thin films on an ITO electrode had a better and satisfactory specific capacitance value, and exhibited more excellent electrochemical stability and reversibility than Ti foil substrates.
摘要:
This paper is concerned with the Cauchy problem of the three-dimensional viscous liquid gas two-phase flow model. We prove the global existence of a strong solution when H-2-norm of the initial perturbation around a constant state is sufficiently small and its L-1-norm is bounded. Moreover, the optimal convergence rates are also obtained for such a solution. (C) 2014 Published by Elsevier Inc.
摘要:
Ni/ZrO2-CeO2-Al2O3 catalysts were prepared by the precipitation-loading method (Ni-load) and sol gel method (Ni-gel), respectively, and their catalytic performances for syngas production from toluene cracking were investigated by the on-line gas analyzer. The condensed liquid was analyzed by GC-MS. The activity and stability of catalyst, resistance to carbon deposition were also discussed according to the BET, X-ray diffraction (XRD) and scanning electron microscopy (SEM). The results showed that the catalytic activity and stability of the Ni-load catalyst was better than that of Ni-gel catalyst. Ni-load catalyst was able to reduce the carbon deposition under partial oxygen (air flow) compared with under the carrier gas N-2, carbon deposition rate decreased from 15.6% under N-2 to 9.3% under air. The results of BET clearly showed that the specific surface area of Ni-load increased from 18.831 m(2)/g before reaction to 22.439 m(2)/g after reaction under the atmosphere of air, which enhanced the catalyst catalytic activity and stability. The picture of XRD indicated that the Ni-load catalyst under air could improve the degree of dispersion of NiO compared with under the atmosphere of N-2, which could significantly promote the catalyst catalytic activity.

摘要:
A new strategy for the synthesis of 1,3,4-oxadiazoles was established through direct annulation of hydrazides with methyl ketones. It was found that the use of K2CO3 as a base achieves an unexpected and highly efficient C–C bond cleavage. This reaction is proposed to go through oxidative cleavage of Csp3–H bonds, followed by cyclization and deacylation.

摘要:
In this paper, we develop a novel regularisation method for MVAR via weighted fusion which considers the correlation among variables. In theory, we discuss the grouping effect of weighted fusion regularisation for linear models. By virtue of the probability method, we show that coefficients corresponding to highly correlated predictors have small differences. A quantitative estimate for such small differences is given regardless of the coefficients signs. The estimate is also improved when consider empirical approximation error if the model fit the data well. We then apply the proposed model on several time series data sets especially a time series dataset of human gut microbiomes. The experimental results indicate that the new approach has better performance than several other VAR-based models and we also demonstrate its capability of extracting relevant microbial interactions.

摘要:
A series of sodium methyl(α-(substituted phenoxyacetoxy)alkyl)phosphinates was designed and synthesized. Their structures were confirmed by IR, 1H NMR and elemental analysis, and some of them were further confirmed by MS. The results of bioassay showed that most of title compounds exhibited moderate to good herbicidal activities against the root of barnyard grass and rape at 10∼100 mg/L.

摘要:
Using a data sample of 106 million psi(3686) events collected with the BESIII detector operated at the BEPCII storage ring, we study for the first time the decays chi(cJ) -> phi(KSK +/-)-K-0 pi(-/+) and chi(cJ) -> phi K+K-pi(0) in the E1 radiative transition psi(3686) -> gamma chi(cJ). The decays are dominated by the three-body decay chi(cJ) -> phi K*(892)(K) over bar. We measure branching fractions for this reaction via the neutral and charged K*(892) and find them consistent with each other within the expectation of isospin symmetry. In the K (K) over bar pi invariant mass distribution, a structure near the K*(892)(K) over bar mass threshold is observed, and the corresponding mass and width are measured to be 1412 +/- 4(stat) +/- 8(sys) MeV/c(2) and Gamma = 84 +/- 12(stat) +/- 40(sys) MeV, respectively. The observed state favors an assignment to the h(1)(1380), considering its possible J(PC) and comparing its mass, width and decay mode to those reported in the Particle Data Group.

摘要:
Glutathione (GSH) is a major endogenous antioxidant that has a central role in cellular defense against toxins and free radicals. This protocol describes the preparation of CPDSA, a cyanine-based near-infrared (NIR) fluorescent probe for the detection of GSH in cells and in vivo. CPDSA is prepared with high yield through a simple two-step process. The first step is to react commercially available IR-780 iodide with excess anhydrous piperazine in anhydrous N,N-dimethyl formamide at 85 °C to form cyanine-piperazine (CP). The second step is the sulfonylation of CP with dansyl chloride in anhydrous dichloromethane. CPDSA selectively detects GSH in cells, and it has been shown to not react with other biothiols such as cysteine (Cys) and homocysteine (Hcy). This probe can also be used to monitor the GSH level of mouse bone marrow-derived neutrophils (BMDNs). The preparation of probe CPDSA takes 2 d, and experiments in cells and mice take 12-13 d.
