We present the theory and numerical results for interferometrically interpolating and extrapolating ocean bottom seismic (OBS) and surface seismic profile (SSP) data. For the interpolation of OBS data we use the combination of a natural Green’s function (i.e. OBS shot gather) and a model-based Green’s function for the water-layer model. Results show that the aliased OBS data with 80 meter geoph...

The Water Sector Government Coordinating Council (GCC) is pleased to concur on the 2007 Water Sector-Specific Plan (SSP). This plan provides the overarching framework for integrating Water Sector critical infrastructure and key resource protection efforts into a unified program coordinated by the Department of Homeland Security (DHS). Through direct collaboration, the Water Sector Coordinating ...

Chenopodium album L. ssp. album is a common plant species worldwide, especially in humid areas. Sun exposure after oral intake of the plant can lead to sunburn-like rashes owing to its furocoumarin content. In this article, we reported nine patients who developed dermatitis with edema, erythema and necrosis on the face and dorsum of the hands. Each was exposed to sunlight after eating selemez (...

In this contribution, new chromosome data obtained on material collected in Italy are presented. It includes counts for Centaurea aegusae , Hieracium racemosum subsp. lucanum, H. australe australe, Lysimachia arvensis arvensis, Micromeria graeca graeca, and M. consentina.

We present STEREO, a system that offers an expressive formalism and implements techniques firmly grounded on logic to solve the Service Selection Problem (SSP). STEREO adopts the Local-As-View approach (LAV) to represent services’ functionality as views on ontology concepts, while user requests are expressed as conjunctive queries on these concepts. Additionally, users can describe their prefer...

We apply the concept of effective order to strong stability preserving (SSP) explicit Runge–Kutta methods. Relative to classical Runge–Kutta methods, methods with an effective order of accuracy are designed to satisfy a relaxed set of order conditions, but yield higher order accuracy when composed with special starting and stopping methods. We show that this allows the construction of four-stag...

In this paper we review and further develop a class of strong stability-preserving (SSP)high-order time discretizations for semidiscrete method of lines approximations of par-tial differential equations. Previously termed TVD (total variation diminishing) timediscretizations, these high-order time discretization methods preserve the strong stabil-ity properties of first-order Eu...

We apply the concept of effective order to strong stability preserving (SSP) explicit Runge–Kutta methods. Relative to classical Runge–Kutta methods, effective order methods are designed to satisfy a relaxed set of order conditions, but yield higher order accuracy when composed with special starting and stopping methods. The relaxed order conditions allow for greater freedom in the design of ef...

Strong stability-preserving (SSP) Runge–Kutta methods were developed for time integration of semidiscretizations of partial differential equations. SSP methods preserve stability properties satisfied by forward Euler time integration, under a modified time-step restriction. We consider the problem of finding explicit Runge–Kutta methods with optimal SSP time-step restrictions, first for the cas...
