A graft is a representation of an even cut matroid M if the cycles of M correspond to the even cuts of the graft. Two, long standing, open questions regarding even cut matroids are the problem of finding an excluded minor characterization and the problem of efficiently recognizing this class of matroids. Progress on these problems has been hampered by the fact that even cut matroids can have an...

OBJECTIVE To determine the trade-off between the sensitivity and the specificity for high grade cervical intraepithelial neoplasia at hybrid capture 2 cut-off values above the standard ≥ 1 relative light units/cut-off level (rlu/co). DESIGN Systematic review. DATA SOURCES PubMed. STUDY SELECTION Randomised controlled trials in primary cervical screening using hybrid capture 2 testing in t...

CONTEXT To improve the management of cancer-related symptoms, systematic screening is necessary, often performed by using 0-10 numeric rating scales. Cut points are used to determine if scores represent clinically relevant burden. OBJECTIVES The aim of this systematic review was to explore the evidence on cut points for the symptoms of the Edmonton Symptom Assessment Scale. METHODS Relevant...

Cheeger cut has recently been shown to provide excellent classification results for two classes. Whereas the classical Cheeger cut favors a 50-50 partition of the graph, we present here an asymmetric variant of the Cheeger cut which favors, for example, a 10-90 partition. This asymmetric Cheeger cut provides a powerful tool for unsupervised multi-class partitioning. We use it in recursive bipar...

BACKGROUND Male circumcision (MC) reduces HIV acquisition and is a key public health intervention in settings with high HIV prevalence, heterosexual transmission and low MC rates. In Papua New Guinea (PNG), where HIV prevalence is 0.8%, there is no medical MC program for HIV prevention. There are however many different foreskin cutting practices across the country's 800 language groups. The maj...

in the open-pit mining, one of the first decisions that must be made in production planning stage, after completing the design of final pit limits, is determining of the processing plant cut-off grade. since this grade has an essential effect on operations, choosing the optimum cut-off grade is of considerable importance. different goals may be used for determining optimum cut-off grade. one of...

I n 2005, the International Diabetes Federation (IDF) and the Japanese Committee for the Diagnostic Criteria of Metabolic Syndrome (Japanese definition) proposed metabolic syndrome definitions for the Japanese population (1,2). Both definitions included waist circumference as an essential component and adopted cut points of 85 cm for men and 90 cm for women based on the relationship between wai...

abstract   background : although, different studies on end-to-side nerve repair, results are controversial. the importance of this method in case is unavailability of proximal nerve. in this method, donor nerves also remain intact and without injury. in compare to other classic procedures, end-to-side repair is not much time consuming and needs less dissection. overall, the previous studies in ...

To evaluate the effect of nanosilver (5, 10 and 20 mg l-1), hydrogen peroxide (200, 400 and 600 µM) and Nanosil (200, 400 and 600 µM) as antimicrobial compounds in vase solution of cut rose cv. ‘Grand Press Angela’ flowers, an experiment with 10 treatments and 3 replications was conducted in a completely randomized design. Cut rose flowers were continuously treated with these compounds. The res...

The Drosophila selector gene cut is a hierarchal regulator of external sensory organ identity and is required to pattern the sensory and nonsensory cells of the wing margin. Cut performs the latter function, in part, by maintaining expression of the secreted morphogen encoded by wingless (wg). We find that Cut is required for wing-margin sensory organ specification in addition to and independen...
