TL;DR: The current status of research on the mechanical properties of carbon nanotubes (CNTs) and composites containing them is reviewed in this article, where the applicability of the concepts of classical mechanics for describing the behavior of nanometer-sized objects is analyzed.
Abstract: The current status of research on the mechanical properties of carbon nanotubes (CNTs) and composites containing them is reviewed. The structural features of CNTs determining their mechanical characteristics are considered. The applicability of the concepts of classical mechanics for describing the behavior of nanometer-sized objects is analyzed. The results of experimental investigations into the mechanical characteristics of CNTs and macroscopic objects containing nanotubes are discussed. The problem of reinforcement of polymer materials as a result of inserting carbon nanostructures is reviewed. Examples showing the effective operation of nanoelectromechanical systems (NEMSs) are analyzed.

TL;DR: The PHENIX experiment has measured electrons and positrons at midrapidity from the decays of hadrons containing charm and bottom quarks produced in d+Au and p+p collisions, and shows that the mass-dependent Cronin enhancement observed at the Relativistic Heavy Ion Collider extends to the heavy D meson family.
Abstract: The PHENIX experiment has measured electrons and positrons at midrapidity from the decays of hadrons containing charm and bottom quarks produced in d+Au and p+p collisions at sqrt[S(NN)]=200 GeV in the transverse-momentum range 0.85 ≤ p(T)(e) ≤ 8.5 GeV/c. In central d+Au collisions, the nuclear modification factor R(dA) at 1.5

TL;DR: In this paper, a search is performed for a heavy Majorana neutrino (N), produced in leptonic decay of a W boson propagator and decaying into a W-broson and a lepton, with the CMS detector at the LHC.
Abstract: A search is performed for a heavy Majorana neutrino (N), produced in leptonic decay of a W boson propagator and decaying into a W boson and a lepton, with the CMS detector at the LHC. The signature used in this search consists of two same-sign leptons, in any flavor combination of electrons and muons, and at least one jet. The data were collected during 2016 in proton-proton collisions at a center-of-mass energy of 13 TeV, corresponding to an integrated luminosity of 35.9 fb(-1). The results are found to be consistent with the expected standard model background. Upper limits are set in the mass range between 20 and 1600 GeV in the context of a Type-I seesaw mechanism, on |V-eN|(2), |V-N|(2), and |VeNV *|(2)/(|V-eN|(2)+|V-N|(2)), where V-N is the matrix element describing the mixing of N with the standard model neutrino of flavor = e, . For N masses between 20 and 1600 GeV, the upper limits on |V-N|(2) range between 2.3 x 10(-5) and unity. These are the most restrictive direct limits for heavy Majorana neutrino masses above 430 GeV.

TL;DR: In this article, the authors re-examine PISN properties using progenitor models computed with the GENEC code and calculate supernova explosions with FLASH and light curve evolution with the radiation hydrodynamics code STELLA.
Abstract: With an increasing number of superluminous supernovae (SLSNe) discovered the question of their origin remains open and causes heated debates in the supernova community. Currently, there are three proposed mechanisms for SLSNe: (1) pair-instability supernovae (PISN), (2) magnetar-driven supernovae, and (3) models in which the supernova ejecta interacts with a circumstellar material ejected before the explosion. Based on current observations of SLSNe, the PISN origin has been disfavoured for a number of reasons. Many PISN models provide overly broad light curves and too reddened spectra, because of massive ejecta and a high amount of nickel. In the current study we re-examine PISN properties using progenitor models computed with the GENEC code. We calculate supernova explosions with FLASH and light curve evolution with the radiation hydrodynamics code STELLA. We find that high-mass models (200 and 250 solar masses) at relatively high metallicity (Z=0.001) do not retain hydrogen in the outer layers and produce relatively fast evolving PISNe Type I and might be suitable to explain some SLSNe. We also investigate uncertainties in light curve modelling due to codes, opacities, the nickel-bubble effect and progenitor structure and composition.

TL;DR: In this article, the correlation of these produced particles with respect to the reaction plane was analyzed with the FOPI detector system, and it was shown that baryons exhibit a very pronounced sideward flow pattern which is qualitatively similar to the proton flow.
Abstract: Particles with strange quark content produced in the system 1.93A·GeV58Ni on58Ni have been investigated at GSI Darmstadt with the FOPI detector system. The correlation of these produced particles was analyzed with respect to the reaction plane.Λ baryons exhibit a very pronounced sideward flow pattern which is qualitatively similar to the proton flow. However, the kaon (K

) flow patterns are significantly different from that of the protons, and their form may be useful to restrict theoretical models on the form of the kaon potential in the nuclear medium.
