We characterize the natural diagonal almost product (locally product) structures on the tangent bundle of a Riemannian manifold. We obtain the conditions under which the tangent bundle endowed with the determined structure and with a metric of natural diagonal lift type is a Riemannian almost product (locally product) manifold, or an (almost) para-Hermitian manifold. We find the natural diagona...

Massless diquark jet and gluon jet productions at large transverse momentum in the coherent diffractive processes at hadron colliders are studied in the two-gluon exchange parametrization of the Pomeron model. We use the helicity amplitude method to calculate the cross section formulas. We find that for the light quark jet and gluon jet production the diffractive process is related to the diffe...

We explore the role of Majoron (J) emission in the supernova cooling process, as a source of the upper bound on neutrino-Majoron coupling. We show that the strongest upper bound on the coupling to νe comes from the νeνe → J process in the core of a supernova. We also find bounds on diagonal couplings of the Majoron to νμ(τ)νμ(τ) and on off-diagonal νeνμ(τ) couplings in various regions of the pa...

treated tumor (center). The peak pyruvate signal has been scale to 1 and the origin of time (t=0) has been chosen to coincide with the peak of the pyruvate signal. The panel at right shows an axial proton image of the tumor (indicated by the green ellipse) and the location of the surface coil (indicated by the red line). The diagonal line at upper left is a water-filled fiducial marker. Monitor...

Understanding the underlying processes and extracting detailed characteristics of rivers is critical has not yet been fully developed. The purpose this study was to examine performance non-linear time series methods on environmental data. Specifically, we performed an analysis water level measurements, extracted from sensors, located specified stations along Nestos River (Greece), with Recurren...

We provide a proof that entanglement of any density matrix which is block diagonal in subspaces are disjoint terms the Hilbert space one two potentially entangled subsystems can simply be calculated as weighted average present within each block. This especially useful for thermal-equilibrium states always inherit symmetries Hamiltonian, since block-diagonal Hamiltonians common, interactions inv...

A symmetrized version of the recently developed refined Robert-Bonamy formalism [Q. Ma, C. Boulet, and R. H. Tipping, J. Chem. Phys. 139, 034305 (2013)] is proposed. This model takes into account line coupling effects and hence allows the calculation of the off-diagonal elements of the relaxation matrix, without neglecting the rotational structure of the perturbing molecule. The formalism is ap...
