Field experiments were conducted in 1989 and 1990 to examine the population fluctuation patterns of Tylenchorhynchus nudus, Criconemella curvata, and Helicotylenchus cornurus in mixed bentgrass and annual bluegrass putting greens on two golf courses near Chicago, Illinois, to determine if fluctuation patterns could be extrapolated to unsampled greens. Fenamiphos-treated and untreated plots were...

In this paper the consistency of the de Sitter invariant α-vacua, which have been introduced as simple tools to study the effects of transplanckian physics, is investigated. In particular possible non renormalization problems are discussed, as well as non standard properties of Greens functions. We also discuss the non thermal properties of the α-vacua and the necessity of α to change. The conc...

How...

We present, here, advanced DFT-NEGF techniques that we have implemented in our ATOmistic MOdelling Solver, ATOMOS, to explore transport novel materials and devices particular van-der-Waals heterojunction transistors. describe methodologies using plane-wave DFT, followed by a Wannierization step, linear combination of atomic orbital leads an orthogonal non-orthogonal NEGF model, respectively. th...

Most common implementations of the NEGF approach are done using the Finite-Difference Method (FDM) on uniform grids. This discretization scheme allows one to study many types of planar devices, such as MOSFETs, superlattices and planar heterojunctions. Within this paradigm, carrier scattering can be included through the selfenergy approach, almost always under the assumption of local interactio...

In a recent Letter [Balzer \textit{et al.}, Phys. Rev. Lett. \textbf{121}, 267602 (2018)] it was demonstrated that ions impacting correlated graphene cluster can excite strongly nonequilibrium states. particular, this lead to an enhanced population of bound pairs electrons with opposite spin -- doublons where the doublon number be increased via multiple ion impacts. These predictions were made ...

The understanding and modeling of heat transport across nanometer subnanometer gaps, where the distinction between thermal radiation conduction becomes blurred, remains an open question. In this work, we present a three-dimensional atomistic simulation framework by combining molecular dynamics (MD) phonon nonequilibrium Green's function (NEGF) methods. relaxed atomic configuration interaction f...

The space-time Greens functions for 3-D poststack and 3-D prestack migration in a homogeneous medium are derived under the far-field approximation. These Greens functions can be used to practically compute synthetic migrated images. Examples are given for the recording footprint noise associated with a point scatterer and a meandering river channel. The Greens functions also provide fundamental...

A three-dimensional model of binary chemical reactions is studied. We consider an ab initio quantum two-particle system subjected to an attractive interaction potential and to a heat bath at thermal equilibrium at absolute temperature T > 0. Under the sole action of the attraction potential, the two particles can either be bound or unbound to each other. While at T = 0, there is no transition b...
