Long Scarf Syndrome; Accidental Strangulation due to Long Scarf
Loose clothing worn by Indian women get accidently entangled in moving wheel of motor bike or crop thresher and cause accidental strangulation. This study is about the patients admitted in department of otorhinolaryngology with history of accidental strangulation due to long scarf. This study showed that women in rural area are at risk of accidental strangulation due to long scarf getting entra...
متن کاملScarf Oiks
We formulate the famous Scarf Lemma in terms of oiks. This lemma has two fundamental applications in game and graph theory. In 1967, Scarf derived from it core-solvability of balanced cooperative games. Recently, it was shown that kernelsolvability of perfect graphs also results from this lemma. We show that Scarf’s combinatorially defined oiks are in fact realized by polytopes, and that Scarf’...
متن کاملOn a Lemma of Scarf
The aim of this note is to point out some combinatorial applications of a lemma of Scarf, proved first in the context of game theory. The usefulness of the lemma in combinatorics has already been demonstrated in [1], where it was used to prove the existence of fractional kernels in digraphs not containing cyclic triangles. We indicate some links of the lemma to other combinatorial results, both...
متن کاملScarf is Ppad-Complete
Scarf’s lemma is one of the fundamental results in combinatorics, originally introduced to study the core of an N -person game. Over the last four decades, the usefulness of Scarf’s lemma has been demonstrated in several important combinatorial problems. However, the complexity of the computational version of Scarf’s lemma (Scarf) is unknown. In this paper, we prove that Scarf is complete for t...
متن کاملExtensions to the scarf framework
The scarf framework as presented [2] offers the basic equations for training SCRFs. We propose to extend the framework with Empirical Bayes Risk training or Empirical Training Error optimization, which are better correlated with the error metric one seeks to optimize, than the conditional log-likelihood normally used. Second, SCRFs are (marginalized) exponential models over segmented sequences....
