We show that several constraint propagation algorithms (also called (local) consistency, consistency enforcing, Waltz, filtering or narrowing algorithms) are instances of algorithms that deal with chaotic iteration. To this end we propose a simple abstract framework that allows us to classify and compare these algorithms and to establish in a uniform way their basic properties. Note. This is a ...

2014 The structures of thin lamellar films can be determined through a combination of three X-ray experiments using synchrotron radiation. Diffraction experiments in the transmission geometry give the intralamellar ordering, the diffraction at small glancing angles yields the interlamellar organization, and the critical reflection provides the density measurement which is required to obtain the...

Abstract HAWC J1826−128 is one of the brightest Galactic TeV γ -ray sources detected by High Altitude Water Cherenkov (HAWC) observatory, with photon energies extending up to nearly ∼100 TeV. This source spatially coincides H.E.S.S. HESS J1826−130 and “Eel” pulsar wind nebula (PWN), which associated GeV PSR J1826−1256. In X-ray band, Chandra XMM-Newton revealed that Eel PWN composed both a comp...

This study is an attempt to build a contemporary linguistic corpus for Arabic language. The corpus produced, is a text corpus includes more than five million newspaper articles. It contains over a billion and a half words in total, out of which, there is about three million unique words. The data were collected from newspaper articles in ten major news sources from eight Arabic countries, over ...

The Tn551 insertion site of the autolysis-deficient Staphylococcus aureus mutant RUSAL2 was cloned and used to identify the autolysis gene atl in the parent strain, RN450. The open reading frame for atl was 3768 bp in length, encoding a deduced protein of 1256 amino acids and molecular size of 137,381 Da. The atl gene product is a bifunctional protein that has an amidase domain and an endo-beta...

Objective To study acute poisoning in Sri Lankan children. Design A prospective hospital based study. Setting Lady Ridgeway Hospital for Children, Colombo. Patients Children with suspected acute poisoning admitted to hospital from January 1985 to January 2000. Results There were 2100 children with acute poisoning. 1256 (60%) were males. 1643 (78%) were below 4 years of age. Route of poisoning w...

Cardiac rupture during stress testing is uncommon and rarely reported, with less than ten cases described in the scientific literature. We present a patient with left ventricular free wall rupture one week after a nontransmural acute myocardial infarction (AMI), when undergoing conventional stress testing. A 70-year-old man, ex-smoker, with no other cardiovascular risk factors, was admitted in ...
