We present threshold enhanced QCD corrections to the bottom quark energy distribution in Higgs boson decay and to hadroproduction in l + l − annihilation beyond leading order in the strong coupling constant. This is achieved using the resummed decay distribution obtained using renormal-isation group invariance and the mass factorisation theorem that they satisfy and Sudakov resum-mation of soft...

Complex pieces of machinery require regular systematic preventative maintenance to sustain their high-performance standards. The same is true with the complex human "machinery" that runs medical group practices. The behaviors, skills, and attitudes that are often referred to as the "soft 'touchy-feely' stuff" are not a luxury. Quite the contrary--they are essential to achieving and maintaining ...

We study how next-to-leading logarithms modify predictions from leading logarithmic soft-gluon resummation in the heavy quark production cross section near threshold. Numerical results are presented for top quark production at the Fermilab Tevatron and bottom quark production at fixed-target energies.

Recent studies have documented strong, top-down predation effects of sea ducks on mussel populations in rocky intertidal communities. However, the impact of these gregarious predators in soft-bottom communities has been largely unexplored. We evaluated effects of predation by wintering surf scoters Melanitta perspicillata and white-winged scoters M. fusca on clam populations in soft-bottom inte...

in this work, we define a fuzzy soft set theory and its related properties. we then define fuzzy soft aggregation operator that allows constructing more efficient decision making method. finally, we give an example which shows that the method can be successfully applied to many problems that contain uncertainties.

Concrete piles that were poorly constructed or analyzed in their soil analyses may have structural geotechnical defects. To examine such defects, an experimental study was conducted to investigate how a defective reinforced concrete pile behaved. These installed and subjected compression axial load the sand had relative densities of 30%,60%, 80%. The tests performed using four model piles: one ...

The potential of ecosystem engineers to modify the structure and dynamics of food webs has recently been hypothesised from a conceptual point of view. Empirical data on the integration of ecosystem engineers and food webs is however largely lacking. This paper investigates the hypothesised link based on a field sampling approach of intertidal biogenic aggregations created by the ecosystem engin...
