A compact IR-drop model for on-chip power distribution networks in wire-bonded ICs is presented. Chip dimensions, metal coverage and piecewise distribution of the IC consumption are taken into account to obtain closed form expressions for the maximum IR-drop as well as its place. Comparison with simulations shows an error as small as 2% in most the cases.

BACKGROUND AND PURPOSE To retrospectively report changes in gross tumor volume (GTV) and organ-at-risk (OAR) doses after induction chemotherapy (IC) in oropharyngeal cancer using different contouring strategies. MATERIALS AND METHODS GTV and OARs were delineated on pre- and post-IC planning CT. Two post-IC GTV contours were made: (1) a 'consensus set' using published guidelines (GTVconsensus)...

dracocephalum kotschyi boiss. (labiatae) is a traditional medicine which is believed to have antispasmodic and analgesic activities. the antispasmodic action of d. kotschyi essential oil has been shown in a previous report. the objective of this research was to study antispasmodic activity of hydroalcoholic extract of d. kotschyi on ileum contractions. hydroalcoholic extract was obtained from a...

abstract   extract prepared from aerial part of pycnocycla spinosa is a relaxant of rat ileum contractions. the objective of this research was to study the spasmolytic activity of p. spinosa root extract for comparison with the aerial part extract. hydroalcoholic extracts were prepared by percolation method. a portion of rat ileum was removed and suspended under 1 g tension in tyrode’s solution...

this paper has examined the phenomenon of convergence of per capita out put levels across the ic countries for the 1960-1998 periods. three concepts of convergence, i.e., sigma beta and relative beta, have been used. the estimated beta values reveals only a very weak convergence (?=.0014) across ic for 1960-1998 period. but when a more homogeneous group of countries were selected, the results s...

Background: Acute drug poisoning remains an important public health problem and represents the second most frequent accidental disease in children. In this study, we identified epidemiological and clinical features of children admitted for acute drug poisoning and related factors associated with suicidal poisoning. Methods: We conducted a retrospective study in the Department of Pediatrics, ...
