Freshwater Bivalve Extinctions (Mollusca: Unionoida): A Search for Causes
The freshwater bivalves (Mollusca: Order Unionoida) are classified in six families and about 165 genera worldwide. Worldwide rate of extinction of freshwater bivalves is poorly ...
A semi‐empirical <scp>MO</scp> theory for ionization potentials and electron affinities
Abstract A method for calculating the vertical ionization potentials and electron affinities according to their fundamental definition as differences between energies of the sin...
Probing Individual Molecules with Confocal Fluorescence Microscopy
Confocal fluorescence microscopy coupled with a diffraction-limited laser beam and a high-efficiency detection system has been used to study the diffusive movement and emission ...
Reducing uncertainty in projections of extinction risk from climate change
ABSTRACT Aim Concern over the implications of climate change for biodiversity has led to the use of species–climate ‘envelope’ models to forecast risks of species extinctions un...
Climate change in Australian tropical rainforests: an impending environmental catastrophe
It is now widely accepted that global climate change is affecting many ecosystems around the globe and that its impact is increasing rapidly. Many studies predict that impacts w...
Nonlinear amplifying loop mirror
A novel device arrangement for all-optical switching that permits efficient exploitation of waveguide nonlinearities is discussed. It is based on a long optical fiber loop mirro...
Nanosphere Lithography: Effect of the External Dielectric Medium on the Surface Plasmon Resonance Spectrum of a Periodic Array of Silver Nanoparticles
In this paper we examine the effect of solvent on the optical extinction spectrum of periodic arrays of surface-confined silver nanoparticles fabricated by nanosphere lithograph...
Surface-Plasmon Resonance Effect in Grating Diffraction
Anomalies found in the intensity of $p$-polarized light from concave diffraction gratings have been analyzed in terms of an interaction between the incoming photon and a surface...
Probing many-body states of ultracold atoms via noise correlations
We propose to utilize density-density correlations in the image of an\nexpanding gas cloud to probe complex many body states of trapped ultra-cold\natoms. In particular we show ...
Localization of Light
Since the beginning of scientific inquiry the nature of light has played a vital role in our understanding of the physical world. Physicists have marveled at the dual nature of ...
