Nitrogen dioxide is a highly toxic reactive nitrogen species (RNS) recently discovered as an inflammatory oxidant with great potential to damage tissues. We demonstrate here that cell death by RNS was caused by c-Jun N-terminal kinase (JNK). Activation of JNK by RNS was density dependent and caused mitochondrial depolarization and nuclear condensation. JNK activation by RNS was abolished in cel...

wireless sensor networks are composed of hundreds or thousands of small nodes called sensor that work together and are associated with a specific task or tasks to do. each of these nodes includes sensor, processor, communication components, a small memory and a source of energy. it is expected that wireless sensor networks will be used widely in many applications in near future. scalability and...

To identify Rns-regulated genes, a maltose binding protein (MBP)-Rns fusion protein was used to isolate DNA fragments from enterotoxigenic Escherichia coli genomic DNA that carry Rns binding sites. In vivo transcription fusion analysis shows that Rns positively regulates the expression of the open reading frame of yiiS, which lies immediately downstream of one MBP-Rns-bound fragment.

An SK6 cell line (SK6c26) which constitutively expressed the glycoprotein E(rns) of classical swine fever virus (CSFV) was used to rescue CSFV E(rns) deletion mutants based on the infectious copy of CSFV strain C. The biochemical properties of E(rns) from this cell line were indistinguishable from those of CSFV E(rns). Two E(rns) deletion mutants were constructed, virus Flc23 and virus Flc22. V...

Residue number systems (RNS) present the advantage of fast addition and multiplication over other number systems, and have thus received much attention for high-throughput computations. Digit-parallel, carry-free, and constant-time multiplication and addition is a unique feature of RNS. However, certain operations such as overflow detection, magnitude comparison, and division are quite difficul...

This paper introduces a method for extracting the core of a Residue Number System (RNS) number within the RNS, this affording a new method for scaling RNS numbers. Suppose an RNS comprises a set of co-prime moduli, mi, with ∏mi = M. This paper describes a method for approximately scaling such an RNS number by a subset of the moduli, ∏mj = MJ ≈ √M, with the characteristic that all computations a...

BACKGROUND Patients are admitted to hospitals everyday with clinical conditions that can change dynamically resulting in adverse outcomes. The rapid response team (RRT) intervention is a formalised resource to respond to the nurse's concerns about such patients before code arrest occurs. Registered nurses (RNs) are in a position to recognise critical changes and to rescue patients at the most o...
