Haemophilus parasuis is a swine pathogen of significant industry concern, but little is known about how the organism causes disease. A related human pathogen, Haemophilus influenzae, has been better studied, and many of its virulence factors have been identified. Two of these, outer membrane proteins P2 and P5, are known to have important virulence properties. The goals of this study were to id...

We explicitly determine all of the transitive groups of degree p2, p a prime, whose Sylow p-subgroup is not isomorphic to the wreath product Z p Z p . Furthermore, we provide a general description of the transitive groups of degree p2 whose Sylow p-subgroup is isomorphic to Z p Z p , and explicitly determine most of them. As applications, we solve the Cayley Isomorphism problem for Cayley objec...

The 3C-like protease (3CLpro) of severe acute respiratory syndrome coronavirus (SARS-CoV) cleaves 11 sites in the polyproteins, including its own N- and C-terminal autoprocessing sites, by recognizing P4-P1 and P1'. In this study, we determined the crystal structure of 3CLpro with the C-terminal prosequence and the catalytic-site C145A mutation, in which the enzyme binds the C-terminal proseque...

We investigate the asymptotic behavior of the entropy numbers of the compact embedding B1 p1,q1(R d , α) ↪→ B2 p2,q2(R ). Here Bs p,q (R d , α) denotes a weighted Besov space, where the weight is given by wα(x) = (1 + |x |2)α/2, and B2 p2,q2 (Rd ) denotes the unweighted Besov space, respectively. We shall concentrate on the so-called limiting situation given by the following constellation of pa...

We study some discrete and continuous variants of the following problem of Erdős: given a finite subset P of R or R, what is the maximum number of pairs (p1, p2) with p1, p2 ∈ P and |p1−p2| = 1?

in this paper, a certain new connectedness of l-fuzzy subsets inl-topological spaces is introduced and studied by means of preclosed sets. itpreserves some fundamental properties of connected set in general topology.especially the famous k. fan’s theorem holds.

The replication proteins encoded in the P2 region of the poliovirus genome induce extensive rearrangement of cellular membranes into vesicles and are a required component of viral RNA replication complexes. To identify distinct viral protein(s) from the P2 region of the genome that were required to form functional RNA replication complexes, the P2 proteins were expressed in addition to P3 in He...

We prove that for any two minor hereditary properties P1 and P2, such that P2 covers P1, and for any graph G ∈ P2 there is a P1bipartition of G. Some remarks on minimal reducible bounds are also included.

Conditions are established on a polynomial f in two variables under which the equality f(P1, P2) = 0 for two orthogonal projections P1, P2 is possible only if P1 and P2 commute.
