Using a model system, we have studied deletion formation in Bacillus subtilis. When the staphylococcal plasmids pSA2100 (7.1 kilobases) and pUB110 (4.5 kilobases) were ligated to one another at their unique XbaI sites and transformed into either rec+ or recE4 strains of B. subtilis, an intramolecular recombination event usually occurred. Two plasmids, one of 2.6 kilobases and the other of 9.0 k...

s away from real time by mapping into the same logical instant independent events or events close enough in the real-time scale. The logical ordering takes into account causal relations between events. Thus, can be considered as an abstract specification of an input event handler (see Section IV-B) If is an input of the real-time system, then defines a time base, that is, an increasing sequence...

When dsDNA polymers containing identical number of base pairs were electrophoresed through a nanopore in a voltage biased silicon nitride membrane, the measured time integral of blocked ionic current (the event-charge-deficit, ecd, Fologea, D., Gershow, M., Ledden, B., McNabb, D. S. et al.., Nano Lett. 2005, 5, 1905-1909) for each translocation event was the same regardless of whether the molec...

introduction: to obtain a baseline for clinical application of electroencephalography in children and to evaluate the electroencephalography findings in children with various acute and chronic cns disorders and non epileptic events.methods: electroencephalography electroencephalography records of 250 patients were studied in neurophysiology departments of queen rania al-abdullah hospital for ch...

PURPOSE VerifyNow antiplatelet assays were performed before and after stenting for various cerebral artery stenoses to determine the effect of the procedure itself to the function of dual antiplatelets given. MATERIALS AND METHODS A total of 30 consecutive patients underwent cerebral arterial stenting procedure were enrolled. The antiplatelet pretreatment regimen was aspirin (100 mg daily) an...

Model-driven engineering (MDE) generally starts from system design model. In this paper, we show how MDE can be extended to the requirements level expressed in requirements models (in KAOS) and be linked with a formal design language (in Event-B). The central idea is to map Goal-Oriented agents to a hierarchy of Event-B machines. A design process is proposed to decompose a system level agent/ma...

In practice, scoring rules elicit good probability estimates from individuals, while betting markets elicit good consensus estimates from groups. Market scoring rules combine these features, eliciting estimates from individuals or groups, with groups costing no more than individuals. Regarding a bet on one event given another event, only logarithmic versions preserve the probability of the give...

Sense-response applications are widely being used for safeguarding critical infrastructure. In such applications, the sensor nodes detect and report events of interest to the base-station which promptly responds with a physical response. A concern that arises immediately is regarding the ability of the sensor nodes to encounter malicious entities that benefit from any form of damage to the crit...
