TL;DR: In this paper, the performance of the modified system is studied using proton-proton collision data at center-of-mass energy √s=13 TeV, collected at the LHC in 2015 and 2016.
Abstract: The CMS muon detector system, muon reconstruction software, and high-level trigger underwent significant changes in 2013–2014 in preparation for running at higher LHC collision energy and instantaneous luminosity. The performance of the modified system is studied using proton-proton collision data at center-of-mass energy √s=13 TeV, collected at the LHC in 2015 and 2016. The measured performance parameters, including spatial resolution, efficiency, and timing, are found to meet all design specifications and are well reproduced by simulation. Despite the more challenging running conditions, the modified muon system is found to perform as well as, and in many aspects better than, previously. We dedicate this paper to the memory of Prof. Alberto Benvenuti, whose work was fundamental for the CMS muon detector.

TL;DR: In this paper, a search for events with jets and missing transverse energy is performed in a data sample of pp collisions collected at 7 TeV by the CMS experiment at the LHC.
Abstract: A search for events with jets and missing transverse energy is performed in a data sample of pp collisions collected at sqrt(s) = 7 TeV by the CMS experiment at the LHC. The analyzed data sample corresponds to an integrated luminosity of 1.14 inverse femtobarns. In this search, a kinematic variable, alphaT, is used as the main discriminator between events with genuine and misreconstructed missing transverse energy. No excess of events over the standard model expectation is found. Exclusion limits in the parameter space of the constrained minimal supersymmetric extension of the standard model are set. In this model, squark masses below 1.1 TeV are excluded at 95% CL. Gluino masses below 1.1 TeV are also ruled out at 95% CL for values of the universal scalar mass parameter below 500 GeV.

TL;DR: Based on research with Bond's Chinese Values Survey (CVS) across 23 countries, Hofstede added a fifth dimension, Long- versus Short-Term Orientation (LTO), to his earlier four IBM-based dimensions of national cultures as mentioned in this paper.
Abstract: Based on research with Bond’s Chinese Values Survey (CVS) across 23 countries, Hofstede added a fifth dimension, Long- versus Short-Term Orientation (LTO), to his earlier four IBM-based dimensions of national cultures. The authors attempted to replicate this dimension by analyzing World Values Survey (WVS) items that seemed to capture the concept of LTO. Their factor analysis of 10 such items across 38 countries resulted in two factors. One was strongly correlated with the original LTO, whereas the other resembled Hofstede’s individualism dimension. The first factor’s nomological network was identical to that of the CVS-based LTO: It predicted national economic growth and national school success in mathematics. These findings show that a dimension very similar to the original LTO can be derived from the WVS and that Chinese and Western research instruments can produce similar dimensions of culture.

TL;DR: In this article, a comparison and discussion of the substantial amount of information about the state and coordination of titanium ions in titanium silicalites is presented, with emphasis on location of the Ti ions in framework or extra-framework positions, their coordination, and the relationship of some spectral features to concrete structures at the atomic level.
Abstract: The review presents a comparison and discussion of the substantial amount of information about the state and coordination of titanium ions in titanium silicalites. The results from structural characterization of titanium silicalites with spectral, electrochemical, and quantum-chemical methods with emphasis on location of the Ti ions in framework or extraframework positions, their coordination, and the relationship of some spectral features to concrete structures at the atomic level are summarized. The main methods for the determination of some specific characteristics of titanium silicalite samples are considered—presence of metal ion impurities, extraframework titania, acidity, hydrophobicity, diffusion, and other sterical restrictions. Speculations on how these properties influence the catalytic activities and selectivities of the samples are discussed. Some experimental results for interaction of molecules—solvents, water, and hydrogen peroxide—with titanium silicalites are also presented. The...
