TL;DR: In this article, the performance of missing transverse momentum (Tmiss) reconstruction algorithms for the CMS experiment is presented, using proton-proton collisions at a center of mass energy of 13 TeV, collected at the CERN LHC in 2016.
Abstract: The performance of missing transverse momentum (Tmiss) reconstruction algorithms for the CMS experiment is presented, using proton-proton collisions at a center-of-mass energy of 13 TeV, collected at the CERN LHC in 2016. The data sample corresponds to an integrated luminosity of 35.9 fb-1. The results include measurements of the scale and resolution of Tmiss, and detailed studies of events identified with anomalous Tmiss. The performance is presented of a Tmiss reconstruction algorithm that mitigates the effects of multiple proton-proton interactions, using the "pileup per particle identification" method. The performance is shown of an algorithm used to estimate the compatibility of the reconstructed Tmiss with the hypothesis that it originates from resolution effects.

TL;DR: In this paper, a meta-analysis of 167 studies investigating the impact of teaching factors on student achievement is presented, showing that factors not included in the model were weakly associated with student learning, with the exception of two factors associated with constructivism.

TL;DR: In this article, the photocatalytic properties of nanocrystalline N-doped TiO 2 were investigated for the reduction of aqueous Cr(VI) in water under both UV and visible light (λ ǫ> 420 õnm) irradiation.
Abstract: A one-step low temperature (180 °C) solvothermal route, which utilized HNO 3 as the nitrogen source, was proposed for the synthesis of nanocrystalline N-doped TiO 2 (denoted as TiO 2 -HNO 3 ). The structure, composition, BET specific surface area and optical properties of TiO 2 -HNO 3 were characterized by X-ray diffraction, Fourier transform infrared spectroscopy, X-ray photoelectron spectroscopy, transmission electron microscopy, high resolution transmission electron microscopy, N 2 adsorption–desorption isotherms and UV–vis diffuse reflectance spectroscopy. The photocatalytic properties of TiO 2 -HNO 3 were tested for the reduction of Cr(VI) in water under both UV and visible light ( λ > 420 nm) irradiation, and compared with those of TiO 2 -NH 3 ·H 2 O (which was solvothermally synthesized using NH 3 ·H 2 O as the nitrogen source) and TiO 2 P25. The photocatalytic results demonstrated that TiO 2 -HNO 3 possessed much higher photocatalytic activity than TiO 2 -NH 3 ·H 2 O and TiO 2 P25 in the reduction of aqueous Cr(VI) under both UV and visible light ( λ > 420 nm) irradiation, and the dosage of TiO 2 -HNO 3 and the initial concentration of Cr(VI) aqueous solution had significant effects on the efficiency of Cr(VI) reduction. Besides, Cr(VI) was reduced to Cr(III) after the TiO 2 -HNO 3 -mediated photocatalytic reactions. The present work suggests that HNO 3 is a promising nitrogen source for low temperature solvothermal synthesis of nanocrystalline N-doped TiO 2 , which can be applied as a visible light-activated photocatalyst in efficient utilization of solar energy for treating Cr(VI) wastewater.

TL;DR: In this paper, a search for massive resonances decaying into a quark and a vector boson (W or Z), or two vector bosons (WW, WZ, or ZZ) was performed on an inclusive sample of multijet events corresponding to an integrated luminosity of 19.7 inverse femtobarns, collected in proton-proton collisions at a centre-of-mass energy of 8 TeV with the CMS detector at the LHC.
Abstract: A search is reported for massive resonances decaying into a quark and a vector boson (W or Z), or two vector bosons (WW, WZ, or ZZ). The analysis is performed on an inclusive sample of multijet events corresponding to an integrated luminosity of 19.7 inverse femtobarns, collected in proton-proton collisions at a centre-of-mass energy of 8 TeV with the CMS detector at the LHC. The search uses novel jet-substructure identification techniques that provide sensitivity to the presence of highly boosted vector bosons decaying into a pair of quarks. Exclusion limits are set at a confidence level of 95% on the production of: (i) excited quark resonances q* decaying to qW and qZ for masses less than 3.2 TeV and 2.9 TeV, respectively, (ii) a Randall-Sundrum graviton G[RS] decaying into WW for masses below 1.2 TeV, and (iii) a heavy partner of the W boson W' decaying into WZ for masses less than 1.7 TeV. For the first time mass limits are set on W' to WZ and G[RS] to WW in the all-jets final state. The mass limits on q* to qW, q* to qZ, W' to WZ, G[RS] to WW are the most stringent to date. A model with a "bulk" graviton G[Bulk] that decays into WW or ZZ bosons is also studied.
