Clp chaperone-proteases are cylindrical complexes built from ATP-dependent chaperonerings that stack onto a proteolytic ClpP double-ring core to carry out substrate protein degradation.Interaction of the ClpP particle with the chaperone is mediated by an N-terminal loop and a hydrophobic surface patch on the ClpP ring surface. In contrast to E. coli, Myco bacterium tuberculosis harbors not only...

We describe a theory of logarithmic Chow rings and tautological subrings for logarithmically smooth algebraic stacks, via generalisation the notion piecewise-polynomial functions. Using this machinery we prove that double-double ramification cycle lies in subring (classical) ring moduli space curves, double is divisorial (as conjectured by Molcho, Pandharipande, Schmitt).

Background Hypertrophic pyloric stenosis (HPS) is a common surgical condition in infancy, and typically presents at 2-4 weeks of age. Case Presentation A full term male neonate in Zeinabieh hospital, Shiraz, Iran was presented with oral feeding intolerance from birth, bile-stained...

1. Let T be a ternary ring with the ternary operation T(a, b, c) and the distinguished elements 0, 1 (see [4]). On T, two loop structures can be defined by means of the binary operations a+b = T(a, 1, b) and ab=T(a, b, 0). The resulting loops are called the additive and the multiplicative loop of Ty respectively. Together with a0 = 0a = 0 they define the structure of a double loop on T, which s...

A 21 year old woman with subacute onset of moderate left hemiparesis showed on CT scanning a left parietal ring shaped enhancing lesion indicative of tumour or abscess, while MRI revealed bilateral white matter lesions highly suggestive of MS. In none of the few similar cases reported was MRI available and most patients underwent biopsy or operation. The few reports of a CT-ring sign in MS are ...
