Unusual water flux in the extracellular polysaccharide of the cyanobacterium Nostoc commune
(Amer Soc Microbiology, 2003-09-01)
Host species affects herbivory, pollination, and reproduction in experiments with parasitic castilleja
(Ecological Society of America, 2003-08)
The relative performance of a parasitic plant on different host species will depend on both direct and indirect effects of hosts on parasite interactions with mutualists and antagonists. Host species could affect parasite ...
Relating the cosmological constant and supersymmetry breaking in warped compactifications of IIB string theory
(American Physical Society, 2003-02-15)
It has been suggested that the observed value of the cosmological constant is related to the supersymmetry breaking scale M-susy through the formula Lambdasimilar toM(p)(4)(M-susy/M-p)(8). We point out that a similar ...
The Changing Pattern of Nontuberculous Mycobacterial Disease
Nontuberculous mycobacteria are human opportunistic pathogens whose source of infection is the environment. These include both slow-growing (eg, Mycobacterium kansasii and Mycobacterium avium) and rapid-growing (eg, ...
Relevance of space anisotropy in the critical behavior of m-axial Lifshitz points
(American Physical Society, 2003-12)
The critical behavior of d-dimensional systems with n-component order parameter phi is studied at an m-axial Lifshitz point where a wave-vector instability occurs in an m-dimensional subspace R-m (m>1). Field theoretic ...
Quark-lepton unification and lepton flavor nonconservation from a TeV-scale seesaw neutrino mass texture
(American Physical Society, 2003-10-01)
In a recent paper we pointed out that the mixing of the light neutrinos with heavy gauge singlet states could reconcile the Z-pole data from e(+)e(-) colliders and the nu(mu) ((nu) over bar (mu)) scattering data from the ...
Vortex transport and voltage noise in disordered superconductors
(Elsevier Science Bv, 2003-02-01)
Shot noise in nanoscale conductors from first principles
(American Physical Society, 2003-04)
We describe a field-theoretic approach to calculate quantum shot noise in nanoscale conductors from first principles. Our starting point is the second-quantization field operator to calculate shot noise in terms of single ...
Food web structure and the role of epilithic biofilms in cave streams
(Ecological Society of America, 2003-09)
Cave stream food webs rely exclusively on detritus from the surface for energy and represent a heterotrophic end point in the continuum of stream types. Both dissolved organic matter (DOM) and particulate organic matter, ...
Three-Dimensional Point Spread Functions Of an Optical Heterodyne Scanning Image Processor
(Optical Society of America, 2003-10-01)
We study the three-dimensional (3-D) imaging properties of an optical heterodyne scanning image processor. The image processor is a two-pupil optical system capable of 3-D imaging coherently or incoherently, depending on ...
