Excluding hooks and their complements
The celebrated Erdős-Hajnal conjecture states that for every n-vertex undirected graph H there exists ε(H) > 0 such that every graph G that does not contain H as an induced subgraph contains a clique or an independent set of size at least n. A weaker version of the conjecture states that the polynomial-size clique/independent set phenomenon occurs if one excludes both H and its complement H. We...
متن کاملA Study on the Holding Capacity Safety Factors for Torpedo Anchors
The use of powerful numerical tools based on the finite-element method has been improving the prediction of the holding capacity of fixed anchors employed by the offshore oil industry. One of the main achievements of these tools is the reduction of the uncertainty related to the holding capacity calculation of these anchors. Therefore, it is also possible to reduce the values of the associated ...
متن کاملA Study on News Anchors’ Meta-Language and Non-Verbal Factors and their Impact on Audiences
Non-verbal communication or body messaging occurs when facial expressions, tone of voice, head and neck movements, smiling and ... affects others; which may be intentional or unintentional. Farhangi in nonverbal communication: the art of using movement and sound” defines this field as such: "Non-verbal communication is phonetic and non-phonetic messages which have been explained by other than l...
متن کاملComparison of holding strength of suture anchors for hepatic and renal parenchyma.
BACKGROUND AND PURPOSE Various laparoscopic devices have been described for suture anchoring during solidorgan parenchymal closure. Application of these devices expedites the closure of parenchymal defects and minimizes ischemia time. We compared different technologies as suture anchors for parenchymal closure. MATERIALS AND METHODS A tensometer was used to determine the amount of tension nec...
متن کاملOn hooks of Young diagrams
The well-known fact that there is always one more addable than removable box for a Young diagram is generalized to arbitrary hooks. As an application, this implies immediately a simple proof of a conjecture of Regev and Vershik 3] for which inductive proofs have recently been given by Regev and Zeilberger 4] and Janson 1].
