چکیده
This paper presents the results of a measurement study of the T1 NSFNET backbone. We rst discuss the measurement environment and approach to data collection. We then present measurements results for: long-term growth in traac volume, including attribu-tion to domains and protocols; trend in average packet size on the network, both over long and medium term intervals; most popular sources, destinations, and site pairs; traac locality; international distribution of traf-c; mean utilization statistics, both of the overall backbone as well as of speciic links of interest; and delay statistics.

The Relationship of Secretion and Activity of Recombinant Factor IX with N-Glycosylation
Background: Human coagulation factor IX (hFIX) is a glycoprotein with two N-glycosylation sites at the activation peptide. Since the activation peptide is removed in mature hFIX, the exact role of N-glycosylation is unclear. To investigate the role of N-glycosylation in the secretion and activity of hFIX, we inhibited N-glycosylation by tunicamycin in the stable Human Embryonic Kidney (HEK)- c...
متن کاملCellular and humoral immune responses to adenoviral vectors containing factor IX gene: tolerization of factor IX and vector antigens allows for long-term expression.
Recombinant adenoviruses containing the canine factor IX (FIX) cDNA were directly introduced in the hind leg muscle of mice. We show that (i) in nude mice, high expression (1-5 micrograms/ml in plasma) of FIX protein can be detected for > 300 days; (ii) in contrast, expression of FIX protein was transient (7-10 days) in normal mice; (iii) CD8+ lymphocytes could be detected within 3 days in the ...
متن کاملA study of reported factor IX use around the world.
Replacement therapy has significantly improved the life expectancy and lifestyle of people with haemophilia. The objectives of this article were to study the reported factor IX (FIX) use on a country-by-country basis and address the following question: Does the reported FIX use vary by national economies? We obtained data on the reported number of international units (IUs) of FIX used for 90 co...
متن کاملRelax and Fix Heuristics for Simultaneous Lot Sizing and Sequencing the Permutation Flow Shops with Sequence-Dependent Setups
This paper proposes two relax and fix heuristics for the simultaneous lot sizing and sequencing problem in permutation flow shops involving sequence-dependent setups and capacity constraints. To evaluate the effectiveness of mentioned heuristics, two lower bounds are developed and compared against the optimal solution. The results of heuristics are compared with the selected lower bound .
