Once and only once.
V enous thrombosis is a fairly common disorder that manifests mainly as deep vein thrombosis of the leg or pulmonary embolism. It affects 1 in 1000 individuals annually and has a substantial mortality rate. 1 Its causes are both genetic (prothrombotic abnormalities sometimes referred to as a group as thrombophilia) and acquired. 2 Among the latter are cancer, female hormone use, and all forms o...
متن کاملDNA Replication: Once, and only once
The preparation for DNA replication initiation is tightly linked to cell-cycle progression, ensuring that replication occurs only once per cycle. The time is ripe for a molecular dissection of the links between the two processes.
متن کاملExtending the Network Calculus Pay Bursts Only Once Principle to Aggregate Scheduling
The Differentiated Services framework allows to provide scalable network Quality of Service by aggregate scheduling. Services, like a Premium class, can be defined to offer a bounded end-to-end delay. For such services, the methodology of Network Calculus has been applied successfully in Integrated Services networks to derive upper bounds on the delay of individual flows. Recent extensions allo...
متن کاملSimultaneous Events and the "Once-Only" Effect
Some events recur, and some happen only once. Galton refers to the latter as “once-only" events [1]. In a first-order logic of events that makes a type-token distinction, the possibility of concurrent occurrences of the same event renders the characterization of the intuitive once-onliness not very intuitive. In particular, the paradigmatic case of the nth occurrence of a recurring event is sho...
متن کاملLimiting DNA replication to once and only once.
In Escherichia coli cells, the origin of chromosomal replication is temporarily inactivated after initiation has occurred. Origin sequestration is the first line of defence against over-initiation, providing a time window during which the initiation potential can be reduced by: (i) titration of DnaA proteins to newly replicated chromosomal elements; (ii) regulation of the activity of the DnaA i...
