Estimating the rate of Web page updates helps in improving Web crawler’s scheduling policy. But, most of the Web sources are autonomous and updated independently. Clients like Web crawlers are not aware of when and how often the sources change. Unlike other studies, we model the process of Web page updates as non-homogeneous Poisson process and focus on determining localized rate of updates. Th...

Ma te ri als and Met hods: Y-splitting surgery. Amount of additional recessions varied with the degree of preoperative deviation by intraoperative adjustable suture technique. Preoperatively 3 patients had esotropia (ET), 6 had exotropia (XT), and 3 patients had orthotropia. The mean preoperative deviation was 19.3 prism diopters (PD) (range, 18-20 PD) in ET patients and 19.2 PD (range, 16-20 P...

The author presents his arguments to state that the Duane’s syndrome type III of the Huber’s classification does not exist. He takes the chance of those arguments to show why the medial rectus muscle recession in Duane’s syndrome with esotropia cripples the adduction more that it does in esotropias of other origins. He shows also why one must recess also the sound eye’s medial rectus in Duane’s...

OBJECTIVE To determine the genetic cause of Duane retraction syndrome (DRS) in 2 families segregating DRS as a dominant trait. METHODS Members of 2 unrelated pedigrees were enrolled in a genetic study. Linkage analysis was performed on the CHN1 locus. Probands and family members were screened for CHN1 mutations. RESULTS The 6 affected individuals in the 2 pedigrees have DRS. Both pedigrees ...
