BACKGROUND & AIMS IL28B polymorphisms, jaundice, decline in HCV-RNA, IP-10, and gender have been proposed to be indicative of spontaneous clearance of acute hepatitis C virus infection. The aim of this study was to define a score enabling the discrimination of patients with spontaneous clearance of HCV from those with development of viral persistence and need for early antiviral treatment. ME...

We give O(log n)-approximation algorithm based on the cut-matching framework of [10, 13, 14] for the computing the sparsest cut on directed graphs. Our algorithm uses only O(log n) single commodity max-flow computations and thus breaks the multicommodity-flow barrier for computing the sparsest cut on directed graphs.

Let G be a minimal imperfect P 5-free graph (i.e. a minimal imperfect graph not containing a path on 5 vertices as induced subgraph) and let S be a minimal cutset of G. In this paper we study several properties of such cutsets, in particular we prove that the subgraph induced by S is connected, contains a P 4 , cannot induce a bipartite subgraph of G .... As a by-product we also give a structur...

alstromeria is a new cut flower in iran that due to the high performance, long life, and pretty flowers and colors diversity is highly regarded. premature yellowing of leaves in cut flowersalstromeria before petal fall is the most important factor limiting the vase life of flowers. to delay leaf yellowing and increased quality, factorial experiment based on completely randomized design carried ...

Background and Objectives: Production and consumption of freshly-cut fruits have been increased in recent decades.  One of the major problems in storage of freshly-cut fruits, the color change, is a result of the oxidative reactions of phenolic compounds by polyphenol oxidases. Various treatments such as coating and refrigeration are used to improve quality and shelf-life of the fresh-cut fruit...

PURPOSE End stage renal disease (ESRD) cases are associated with increased risk of tuberculosis. There is no gold standard method for detecting latent tuberculosis infection (LTBI) in ESRD. The aim of the present study was to analyze the performance of the tuberculin skin test (TST) and QuantiFERON-TB Gold in tube (QFT-G) in cases receiving hemodialysis (HD). METHODS The TST and QFT-G were pr...

Cantaloupes are associated with recent outbreaks of foodborne illnesses and recalls. Therefore, new approaches are needed for sanitization of whole and cut fruit. In the present study, whole cantaloupes were submerged into water in the following 3 conditions: 10 degrees C water for 20 min (control), 20 ppm chlorine at 10 degrees C for 20 min, and 76 degrees C water for 3 min. Populations of mic...

1. Let G = (V,E) be a c-edge connected graph. In other words, assume that the size of minimum cut in G is at least c. Construct a graph G′(V,E ′) by sampling each edge of G with probability p independently at random and reweighing each edge with weight 1/p. Suppose c > log n, and is such that 10 log(n) c 2 ≤ 1. Show that as long as p ≥ 10 log(n) c 2 , with high probability the size of every cut...
