Optimum oo-line algorithms for the list update problem are investigated. The list update problem involves implementing a dictionary of items as a linear list. Several characterizations of optimum algorithms are given; these lead to an implementation of an optimumalgorithm which runs in time O(2 n n!m), where n is the length of the list and m is the number or requests. The previous best algorith...

In the Host Identity Protocol (HIP), the existing host-based handover scheme tends to induce large handover delays and packet loss rates. To deal with this problem, we are proposing a network-based handover scheme for HIP in the mobile networks, in which the access routers of the mobile node will establish a handover tunnel and will perform the route optimization for data transmission. We also ...

Some years ago, a different characterization of the value of a Bermudan option was discovered which can be thought of as the viewpoint of the seller of the option, in contrast to the conventional characterization which took the viewpoint of the buyer. Since then, there has been a lot of interest in finding numerical methods which exploit this dual characterization. This paper presents a pure du...

In this paper, a formal model for antivirus update agent system is presented based on mobile agent technology and predicate/transition Petri nets. The mobile agent system contains two mobile agents called DCA and UNA. It sends out agents to update antivirus on client computers in a network. Each agent takes on a specified responsibility. First, DCA roams through the network and check the last d...

context cystic fibrosis (cf) is the most widespread autosomal recessive genetic disorder that limits life expectation amongst the caucasian population. as the median survival has increased related to early multidisciplinary intervention, other manifestations of cf have emergedespecially for the broad spectrum of hepatobiliary involvement. the present study reviews the existing literature on liv...

hyper ige syndrome (hies) is a rare primary immunodeficiency disease. most of hies cases are sporadic. hies type ad is caused by mutation in signal transducer and activator of transcription-3 (stat-3). a number of mosaicism hies has been reported that is associated with intermediate phenotype. autosomal recessive hies (ar-hies) is due to mutation in dock-8 or cytokine sis 8 and tyk2 or tyrosine...

Oxidative stress has become an important subject for terrestrial and aquatic toxicology. The trace element selenium has been demonstrated in chemo-prevention and drug-resistance through reduction of oxidative stress. Selenium compounds could prevent damage to the unsaturated fatty acid of subcellular membranes by lipid peroxidation induced by free radicals in fish.
