STM2209-STM2208 (opvAB): A Phase Variation Locus of Salmonella enterica Involved in Control of O-Antigen Chain Length
(Public Library of Science, 2012)
STM2209 and STM2208 are contiguous loci annotated as putative protein-coding genes in the chromosome of Salmonella enterica. Lack of homologs in related Enterobacteria and low G+C content suggest that S. enterica may have ...

The Role of the Environment in Tissue P Systems with Cell Division
(Fénix Editora, 2012)
Classical tissue P systems with cell division have a special alphabet whose elements appear at the initial configuration of the system in an arbitrary large number of copies. These objects are shared in a distinguished ...

On the Complexity of Shared Conceptualizations
(Springer, 2012)
In the Social Web, folksonomies and other similar knowledge organization techniques may suffer limitations due to both different users’ tagging behaviours and semantic heterogeneity. In order to estimate how a social ...

Improving GPU Simulations of Spiking Neural P Systems
(Romanian Academy, 2012)
In this work we present further extensions and improvements of a Spiking Neural P system (for short, SNP systems) simulator on graphics processing units (for short, GPUs). Using previous results on representing SNP system ...

Analysis and application of the theories that rationalize the crystalline structures of fluorite-related rare earth oxides
(Elsevier, 2012)
The main current theories dealing with the crystalline structures of the fluorite related rare earth oxides, including those corresponding to reduced oxides, one based on the distribution of the coordination defect inside ...

Studies on the Synthesis of 2-Alkyl-5-aryl-1,3,4-oxadiazolines from N-Acylhydrazones
(2012)
Reaction of N-acylhydrazones with benzyloxyacetyl chloride in the presence of i-Pr 2EtN affords new 1,3,4-oxadiazolines in excellent yields (72-95%), under mild reaction conditions and in short reaction times. The structures ...

Mixed-mode impedance and reflection coefficient of two-port devices
(EMW Publishing, 2012)
From the point of view of mixed-mode scattering parameters, Smm, a two-port device can be excited using different driving conditions. Each condition leads to a particular set of input reflection and input impedance coefficient ...
