Copepods play a critical role in the marine food webs, being source for organisms. In this study, we investigated toxic effects of Water Accommodated Fractions (WAFs) from three types oil: Naphthenic North Sea crude oil (NNS), Intermediate Fuel Oil (IFO 180) and commercial Marine Gas (MGO). The WAFs were prepared at 10 °C 30 PSU (practical salinity unit), tested on copepod Acartia tonsa differe...

The performance and lifespan of a solid-state drive (SSD) depend not only on the current input workload but also on its internal media fragmentation formed over time, as stale data are spread over a wide range of physical space in an SSD. The recently proposed streams gives a means for the host system to control how data are placed on the physical media (abstracted by a stream) and effectively ...

INTRODUCTION Due to drug-drug interactions of HIV- and HCV-specific antivirals when initiating an HCV-therapy, the antiretroviral therapy (ART) often has to be changed. The spectrum of applicable antiretrovirals is small, therefore many patients were switched to raltegravir/truvada (RAL/TVD) in our cohort. Due to the relatively low genetic barrier of RAL, this regimen may be endangered to fail,...

There is a wide range in the reported photon tenth value distance (TVD) in the maze of high-energy linear accelerator vaults. In order to gain insight into the appropriate use of the TVD value during door design, we performed measurements of the photon dose in the maze of four vaults. In addition, our study represents the first to describe a scenario where an inner borated polyethylene (BPE) do...

We present a new multi–fluid, grid MHD code PIERNIK, which is based on the Relaxing TVD scheme (Jin and Xin, 1995). The original scheme (see Trac & Pen (2003) and Pen et al. (2003)) has been extended by an addition of dynamically independent, but interacting fluids: dust and a diffusive cosmic ray gas, described within the fluid approximation, with an option to add other fluids in an easy way. ...

2D Total Variation Denoising (TVD) is a widely used technique for image denoising. It also an important nonparametric regression method estimating functions with heterogenous smoothness. Recent results have shown the TVD estimator to be nearly minimax rate optimal class of bounded variation. In this paper, we complement these worst case guarantees by investigating adaptivity which are piecewise...

Our system to Micro-blog Track at TREC2011 is described in this paper, which includes data obtaining and preprocessing, index building and query expansion. There‟re two methods of query expansion introduced in this report: Word Activation Force algorithm (WAF) and Electric Resistance Network. We also show the evaluation results for our team and the comparison with the best and median evaluations.

We prove that isentropic gas flow does not admit non-degenerate TVD fields on any invariant set M(r0, s0) = {r0 < r < s < s0}, where r, s are Riemann coordinates. A TVD field refers to a scalar field whose spatial variation VarX(φ(τ(t,X), u(t,X))) is nonincreasing in time along entropic solutions. The result is established under the assumption that the Riemann problem defined by an overtaking s...
