In the FPGA (Field Programmable Gate Arrays) design flow, one of the most time-consuming step is the routing of nets. Therefore, there is a need to accelerate it. In [2], the authors have developed a Linear Programming (LP) based framework that parallelizes this routing process to achieve significant speedups (the resulting algorithm is termed as ParaLaR). However, this approach has certain wea...

Variable precision reduction (VPR) and positive region (PRR) are common definitions in attribute reduction. The compacted decision table is an extension of a table. In this paper, we propose another extension, called the weighted both types tables, VPR defined, corresponding discernibility matrices for PRR proposed. Then, algorithms obtaining from presented. relationship between established by ...

The human immunodeficiency virus type 1 (HIV-1) Vpr protein binds to the cellular uracil-DNA glycosylase UNG2 and induces its degradation through the assembly with the DDB1-CUL4 ubiquitin ligase complex. This interaction counteracts the antiviral activity exerted by UNG2 on HIV-1 gene transcription, as previously reported by us. In this work, we show that Vpr expression in the context of HIV-1 ...

and colleagues. The holes allow the mixing of proteins that are usually exclusively nuclear or cytoplasmic. The damage, the mixing, or both may cause a G2 cell cycle arrest that allows the virus to replicate more efficiently. For some time Greene has been studying the ability of Vpr to arrest the cell cycle. Vpr shuttles into the nucleus, so Greene suspected that it could affect the shuttling o...

Human immunodeficiency virus type 1 is able to infect nondividing cells, such as macrophages, and the viral Vpr protein has been shown to participate in this process. Here, we investigated the impact of the recruitment into virus particles of the nuclear form of uracil DNA glycosylase (UNG2), a cellular DNA repair enzyme, on the virus mutation rate and on replication in macrophages. We demonstr...

Visual Place Recognition (VPR), the task of identifying place where an image has been taken from, is at core important robotic problems as relocalization, loop-closure detection or topological navigation. Even for indoors, focus this work, VPR challenging a number reasons, including real-time performance when dealing with large databases ( <inline-formula xmlns:mml="http://www.w3.org/1998/Math/...

Visual Place Recognition (VPR) is the ability to correctly recall a previously visited place using visual information under environmental, viewpoint and appearance changes. An emerging trend in VPR use of sequence-based filtering methods on top single-frame-based matching techniques for route-based navigation. The combination leads varying levels potential performance boosts at increased comput...

In sequential prediction tasks, one repeatedly tries to predict the next element in a sequence. A classical way to solve these problems is to fit an order-n Markov model to the data, but fixed-order models are often bigger than they need to be. In a fixed-order model, all predictors are of length n, even if a shorter predictor would work just as well. We present a greedy algorithm, vpr, for fin...

Routes in ad hoc wireless networks are typically discovered and selected by routing protocols based on a particular single criterion such as shortest path or lowest cost of power. Furthermore, those routing protocols do not capture the mobility of the network nodes nor do they factorize it into the operation of the protocols. In this paper, we feature the Virtual Paths Routing (VPR) Protocol fo...
