We describe an exact branch-and-bound algorithm for the maximum weight clique problem (MWC), called WLMC, that is especially suited for large vertex-weighted graphs. WLMC incorporates two original contributions: a preprocessing to derive an initial vertex ordering and to reduce the size of the graph, and incremental vertex-weight splitting to reduce the number of branches in the search space. E...

This study sought to probe the role of input flooding through listening tasks on the uptake of simple present tense and the present progressive tense among pre - intermediate English a s Foreign Language ( EFL ) learners. To comply with the objective, an experimental design was adopted. 55 pre - intermediate learners participated in the study. They were randomly divided into one control group, ...

Background Pre-eclampsia is one of the main causes of morbidity and mortality among pregnant women. This study was done with the objective of measuring abdominal aorta intima-media thickness, serum level of leptin, and lipid profile in neonates of pre-eclampsia mothers and comparing them with neonates of mothers without pre-eclampsia (control group). Materials and Methods Ninety neonates of pre...

conclusions: patients who were given ketamine before or after cesarean section subcutaneously at incision site had lower pain intensity and less analgesic consumption than patients who were given placebo. patients and methods: sixty patients, aged between 18 and 25 years old, scheduled for elective cesarean section, were enrolled to this double-blind randomized controlled trial study. patients ...

  Background: Postmenopausal onset rheumatoid arthritis (post-RA) is expected to have greater bone mineral density (BMD) loss than premenopauasal onset (pre-RA) due to estrogen deficiency and aging. This study aimed to compare the BMD status of the two RA groups with age-matched non-RA controls.   Methods: The patients with RA on follow-up examination were stratified according to age of onset. ...

protective action of ficus carica leaf ethanolic extract (obtained by maceration) was evaluated in an animal model of hepatotoxicity induced by carbon tetrachloride (ccl4). male albino mice were divided into six groups. group i was normal control group; group ii received olive oil (ccl4 solvent), groups iii-vi received ccl4. after inducing hepatic damage, group iii served as control for ccl4; a...
