CONTRIBUTIONS OF SIGMA-B AND PRFA TO STRESS RESPONSE AND VIRULENCE GENE EXPRESSION IN LISTERIA MONOCYTOGENES
… response and virulence genes. The alternative sigma factor sigmaB is a global regulator of genes active under environmental stress conditions and during stationary phase growth. I identified a large portion of the genes regulated by sigmaB using a promoter consensus sequence search and …

Analyzing the size effect on fracture toughness of mortar through flattened Brazilian tests
… how the elastic modulus E, tensile strength [sigma]t, averaged compressive stress at local maximum loading [sigma]A, and averaged compressive stress at local minimum loading [sigma]B change with size and 2[alpha] (flatness angle). The change of fracture toughness, based on the local maximum …

Analysis of an inequality concerning perturbation of self-adjoint operators
… that if A and B are self-adjoint with dist($\sigma(A),\sigma(B)) \geq \delta$ then there is some $c\sb{sa} < 2$ (independent of A and B) such that $c\sb{sa}\vert\vert\vert AQ - QB\vert\vert\vert \geq \delta\vert\vert\vert Q\vert\vert\vert$ for any Q and any unitary invariant norm …

Scanning electron microscope technique for measuring electrical conductivity: Application to tetrathiafulvalene-tetracyanoquinodimethane
… values are found to be: 0b = 490 ±80 (ncm)-l and sigma-a = 1.21 ±.15 (Ohmcm)-l. The relationship of sigma-a and sigma-b to the elements of the correctly expressed conductivity tensor for TTF-TCNQ is clarified. The influence of contact inhomogeneities on four-probe measurements of the temperature …
