Latest results on inclusive and differential top quark pair single production cross sections are presented using proton-proton collision data collected by the CMS experiment. The measured as a function of various kinematic observables quarks jets leptons event final state. confronted with precise theory calculations used to constrain Standard Model parameters. Measurements performed also high p...

Chiral light–matter interaction between photonic nanostructures with quantum emitters shows great potential to implement spin–photon interfaces for information processing. Position-dependent spin momentum locking of the emitter is important these chiral coupled nanostructures. Here, we report position-dependent coupling dots (QDs) and cross waveguides both numerically experimentally. Four distr...

Absorption spectra of two orthogonal linearly polarized X-rays in a single CeCoGe3 crystal were measured at the ID12 beamline ESRF for energies near K-edges Ge, Co and L23 edges Ce. The X-ray natural linear dichroism (XNLD) was revealed vicinity all absorption edges, which indicates splitting electronic states crystalline field. Mathematical modelling comparison with experimental data allowed i...

We present a combined study of single and double K–K electron transfer cross sections along with the single and double K-shell ionization of Ar induced by Si projectiles in the energy range 0.9–4.0 MeV u−1. The charge-state dependence of the normal and hypersatellite x-rays was used to derive the cross sections for the oneand two-electron processes, respectively. The enhancement in the fluoresc...

evidence acquisition a systematic literature searching of databases medline, embase, and google scholar was done from 1982 and updated in december 2015. search terms were “cholecystectomy”, “laparoscopic cholecystectomy”, “four port laparoscopic cholecystectomy”, “single-incision laparoscopic surgery”. context laparoscopic approach with its several techniques has become the standard method for ...

In this paper, we consider a semiparametric single index panel data model with cross–sectional dependence, high–dimensionality and stationarity. Meanwhile, we allow fixed effects to be correlated with the regressors to capture unobservable heterogeneity. Under a general spatial error dependence structure, we then establish some consistent closed–form estimates for both the unknown parameters an...

The order of magnitude of Raman differential cross sections of radial breathing modes (RBMs) of individual carbon nanotubes is measured for 633 and 785 nm laser excitations. This is shown by both a calibration applied to previously published data from other authors at 785 nm and our own measurements of individual nanotubes at 633 nm excitation. We find typical values of differential cross secti...

We present a mean-field dynamical theory for single semiflexible polymers which can precisely capture, without fitting parameters, recent fluorescence correlation spectroscopy results on single monomer kinetics of DNA strands in solution. Our approach works globally, covering three decades of strand length and five decades of time: it includes the complex cross-overs occurring between stiffness...

1: Introduction A large literature has developed that has examined the diversification strategies most suited to a real estate portfolio. Much of this debate has centred on the relative attractiveness of regional or sector diversification. However, more recent evidence would suggest that improved diversification benefits are not purely driven by either the sector or region in which a property i...
