We introduce and describe the topology of a family of complete immersed manifolds in R N ; having a nice behaviour at innnity, which we call conical type end manifolds. Our main result states that a complete, non compact immersed manifold in R N ; whose lim sup of the norm of the second fundamental form times the intrinsic distance of the manifold to a xed point is strictly less than 1, as the ...
R-type pyocins are high-molecular-weight bacteriocins that resemble bacteriophage tail structures and are produced by some Pseudomonas aeruginosa strains. R-type pyocins kill by dissipating the bacterial membrane potential after binding. The high-potency, single-hit bactericidal kinetics of R-type pyocins suggest that they could be effective antimicrobials. However, the limited antibacterial sp...
We construct Galois covers X(N) over P/Fq(T ) with Galois groups close to GL(r,Fq[T ]/(N)) (r ≥ 3) and rationality and ramification properties similar to those of classical modular curves X(N) over P/Q. As application we find plenty of good towers (with limsup number of rational points genus > 0) of curves over the field Fqr with q elements.
The LCLS generates linearly polarized, intense, high brightness x-ray pulses from planar fixed-gap undulators. While the fixed-gap design supports a very successful and tightly controlled alignment concept, it provides only limited taper capability (up to 1% through canted pole and horizontal position adjustability) and lacks polarization control. The latter is of great importance for soft x-ra...
We extend generalized isoperimetric-type inequalities to iterated Brownian motion over several domains in R. These kinds of inequalities imply in particular that for domains of finite volume, the exit distribution and moments of the first exit time for iterated Brownian motion are maximized with the ball D centered at the origin, which has the same volume as D. Mathematics Subject Classificatio...
We investigate whether the equivalence theorem in f(R)-type gravity is valid also in quantum theory. It is shown that, if the canonical quantization is assumed, the equivalence does not hold in quantum theory.
Rhodothermus marinus Alfredsson et al. 1995 is the type species of the genus and is of phylogenetic interest because the Rhodothermaceae represent the deepest lineage in the phylum Bacteroidetes. R. marinus R-10(T) is a Gram-negative, non-motile, non-spore-forming bacterium isolated from marine hot springs off the coast of Iceland. Strain R-10(T) is strictly aerobic and requires slightly haloph...
Let D be a diagram of a knot or a link L. Suppose that there is a simple closed curve C meeting D in k distinct points which divide D into k arcs α1, α2, . . . , αk with the following properties: (1) Each αi has no self-crossing. (2) If αi crosses over αj at a crossing, then i > j and it crosses over αj at any other crossings with αj . (3) For each i, there exists an embedded disk di such that ...
Gafchromic XR type-R radiochromic film is a relatively new product designed for use at clinical diagnostic x-ray energies both qualitatively and quantitatively. This short note investigates the energy response characteristics of this high-sensitivity radiochromic film for both diagnostic and therapeutic x-ray energies. Results are also compared to conventional silver halide x-ray film for energ...
We present B and R CCD observations of 16 latetype galaxies, mainly Magellanic irregulars and blue compact galaxies, at a limiting surface brightness of μB ∼ 26–27 mag arcsec−2. The sample is derived from a H I-rich subset of an H I survey of late-type dwarfs and consists of objects with – 19.5≤MB ≤–14.4, nine galaxies being fainter than MB=–17 (H0=75 km s−1 Mpc−1). Radial luminosity distributi...
