Understanding mechanisms of coevolution between nuclear and mitochondrial (mt) genomes is a defining challenge in eukaryotic genetics. The angiosperm genus Silene is a natural system to investigate the causes and consequences of mt mutation rate variation because closely related species have highly divergent rates. In Silene species with fast-evolving mtDNA, nuclear genes that encode mitochondr...

We give the first polynomial-time algorithm for coloring vertices of P5free graphs with k colors. This settles an open problem and generalizes several previously known results. Page 2 RRR 2006 21

Abstract Tender Shoots is a randomized controlled trial (RCT) for parents aimed at improving preschool children’s oral language skills relevant later reading. Parents of 72 children ( M = 50 months) were randomly assigned to either Rich Reading and Reminiscing (RRR) condition, Strengthening Sound Sensitivity (SSS) or an Activity-Based Control (ABC) condition. RRR SSS conditions involved dyads c...

background: quality of life in patients represents an important area of assessment. however, attention to health professionals should be equally important. the literature on the quality of life (qol) of emergency physicians is scarce. this pilot study investigated qol in emergency physicians in germany. materials and methods: we conducted a cross?sectional study from january to june in 2015.we ...

A simple routing algorithm to improve vehicle safety on a road network has been proposed. If the is represented by graph with edges and nodes, it enough mark most populated Traffic Accidents (TA) adding attribute of edge some penalty (Dijkstra or Bellman-Ford) will try avoid this automatically. To estimate gain, Relative Risk Ratio RRR= (TAs along route which avoids TA hotspots/TAs original rou...

Abstract. Multilab replication projects such as Registered Replication Reports (RRR) and Many Labs are used to replicate an effect in different labs. Data of these usually analyzed using conventional meta-analysis methods. This is certainly not the best approach because it does make optimal use available data a summary rather than participant analyzed. I propose analyze multilab with individual...

In this paper we propose a methodology for the estimation of Customer Satisfaction (CS) conceived as a Latent variable (LV) specified in the American Customer Satisfaction Index (ACSI) structural model. The current proposal puts forward: the approaches of structural equations based on LISREL (Joreskog, 1978), since it involves the dual problem of indeterminacy of the latent scores and the norma...

Singularity is an inherent characteristic of a closed-chain manipulator. This paper presents an approach to singularity analysis of the planar 3-RRR parallel manipulator. On the basis of screw theory, the motion/force transmission analysis of the manipulator is first achieved. The singularity is classified into three types: constraint singularity, input transmission singularity, and output tran...

Prefix-hijacking attack offers malicious parties to gain access to untraceable IP addresses in Intenet. Border gateway protocol (BGP) is the dominant inter domain routing protocol used in Internet. In this paper, to defend against Prefix Hijacking Attack on border gateway protocol (BGP), we propose to design a route reliability ranking (RRR) algorithm. The algorithm is used to authenticate the ...
