Throttling positive semidefinite zero forcing propagation time on graphs [PDF]
, 2018 Zero forcing is a process on a graph that colors vertices blue by starting with some of the vertices blue and applying a color change rule. Throttling minimizes the sum of the size of the initial blue vertex set and the number of the time steps needed to

Gravitational Effects on the Neutrino Oscillation [PDF]
, 1996 The propagation of neutrinos in a gravitational field is studied. A method of calculating a covariant quantum-mechanical phase in a curved space-time is presented.

Semiclassical Electron Correlation in Density-Matrix Time-Propagation
, 2010 Lack of memory (locality in time) is a major limitation of almost all present time-dependent density functional approximations. By using semiclassical dynamics to compute correlation effects within a density-matrix functional approach, we incorporate ...

Measuring BGP Route Propagation Times [PDF]
IEEE Communications Letters, 2019 We present a methodology to measure the propagation time of BGP routes with BGP route collectors and beacons which accounts for the clock offset error between route source and destinations. We apply it to the RIPE RIS data set comparing 2012 and 2018, showing that the IPv4 route prefix reachability interval and the time to receive the preferred ...

A Reevaluation of Time Domain Reflectometry Propagation Time Determination in Soils
Vadose Zone Journal, 2014 Time domain reflectometry (TDR) is an established method for the determination of apparent dielectric permittivity and water content in soils. Using current waveform interpretation procedures, signal attenuation and variation in dielectric media ...

Real-time pion propagation in finite-temperature QCD
, 2002 We argue that in QCD near the chiral limit, at all temperatures below the chiral phase transition, the dispersion relation of soft pions can be expressed entirely in terms of three temperature-dependent quantities: the pion screening mass, a pion decay ...

Feynman propagator in curved space-time
Physical Review D, 1977 The Wick rotation is generalized in a covariant manner so as to apply to curved manifolds in a way that is independent of the analytic properties of the manifold. This enables us to show that various methods for defining a Feynman propagator to be found in the literature are equivalent where they are applicable. We are also able to discuss the relation

Explicit time-dependent Schrodinger propagators [PDF]
Journal of Physics A: Mathematical and General, 1986 We compute explicitly the time-dependent Schrödinger and heat propagator for the potentials \(-[\lambda^ 2m(m+1)]/\cosh^ 2\lambda x\), a \(\delta\) function potential, several cases of periodic \(\delta\) function potentials and a \(\delta\) function potential in a square well. We also discuss the semiclassical approximation for the \(\delta\) function
