In this paper we study the problem of optimizing the distortion compensation parameter for the Scalar Costa Scheme, which is a practical version of the class of Distortion Compensated Dither Modulation schemes. In the literature, a number of results are known for finding the value of the distortion compensation parameter that maximizes the capacity of the watermarking channel. Instead, in this ...

In the classical herding literature, agents receive a private signal regarding a binary state of nature, and sequentially choose an action, after observing the actions of their predecessors. When the informativeness of private signals is unbounded, it is known that agents converge to the correct action and correct belief. We study how quickly convergence occurs, and show that it happens more sl...

The elimination rate of iohexol, a non-ionic contrast medium, from the blood by hemodialysis, and the elimination rate of iohexol by a dialyzer were studied in 15 patients with chronic renal dysfunction who required angiography or enhanced CT. The elimination rate of iohexol was 19.8% at 15 min after the start of hemodialysis, 30.6% after 30 min, 44.2% after 1 hour, 62.1% after 2 hours and 72.9...

elimination of potyviruses from two commercial iranian garlic populations, hamedan and azar-shahr, through thermotherapy and by meristem tip culture were investigated. the infected bulbs of either one of the populations were initially treated at 30o c for one week and then at 36oc for 5 weeks. the meristems of cloves at two sizes of 0.4-0.6 mm and 0.6-0.8 mm were then cultured on ms medium supp...

healthy hire effect (hhe) is considered as an epidemiological phenomenon, complicating the assessment of a true cause - effect relationship between occupational exposure and health status of workers. the current study was aimed at identification and elimination of hhe in the risk assessment of arterial hypertension (ah) in coal miners. overall, 1553 miners, working in west siberia, were enrolle...

Although acute symptoms recurred during treatment in seven of the cases on aspirin, there was no evidence of recrudescence in the phenylbutazone group.

background: the ob­jective of this study was to find an appropriate approach to asymptomatic malaria in elimination setting through a systematic review. methods: a broad search was conducted to find articles with the words ‘malaria’ in their titles and ‘asymptomatic’ or ‘submicroscopic’ in their texts, irrespective of the type of study conducted. the cochrane, medline/pubmed, and scopus databas...

The developmental changes in caffeine elimination were studied in 7 infants aged between 2 1/2 weeks and 6 months. Adult plasma clearance rate of caffeine was achieved at 3 to 4 1/2 months of age. Plasma half-life and elimination rate reached adult levels after 3 to 4 1/2 months and seemed to exceed adult capacity thereafter. No significant changes in apparent volume of distribution were noted....

BACKGROUND The purpose of this study was to determine the influence of varying large crystalloid infusion volumes, ranging from a volume that has been safely administered to volunteers to a volume that greatly exceeds a practical volume for studies in normovolemic humans, of rapidly infused 0.9% saline on the elimination rate constant in sheep. METHODS Six sheep underwent three randomly order...
