Means of Dispersal [PDF]

open access: yesNature, 1877
IN his great work, “Insecta Maderensia,” Mr. Wollaston remarks upon the great affinity in the coleopterous fauna of Madeira with that of Sicily, and in his “Coleoptera H speridum,” on the northern character of that of the Cape Verde Isles. Mr. Andrew Murray also found that out of 275 Cape Verde species 91 were common to the Canaries and 81 to the ...

Dispersion and Dosimetric Challenges of Hydrophobic Carbon-Based Nanoparticles in In Vitro Cellular Studies

open access: yesNanomaterials
Methodologies across the dispersion preparation, characterization, and cellular dosimetry of hydrophilic nanoparticles (NPs) have been developed and used extensively in the field of nanotoxicology. However, hydrophobic NPs pose a challenge for dispersion

On Principal Spectrum Points/Principal Eigenvalues of Nonlocal Dispersal Operators and Applications [PDF]

open access: yesarXiv, 2013
This paper is to investigate the dependence of the principal spectrum points of nonlocal dispersal operators on underlying parameters and to consider its applications. In particular, we study the effects of the spatial inhomogeneity, the dispersal rate, and the dispersal distance on the existence of the principal eigenvalues, the magnitude of the ...

Dispersal of Bivalves [PDF]

open access: yesNature, 1882
REFERRING to the fact mentioned in Mr. Darwin's letter, that mussels are sometimes brought up on the point of a hook, it is common, in shell collections, to find “Heart Cockles” (Isocardia cor), which look exactly as if they had been drilled each with a small hole, centred at some point in the opposed edges of the two valves.

Analysis of high-order dispersion on ultrabroadband microresonator-based frequency combs [PDF]

open access: yesarXiv, 2014
We numerically investigate the influence of high-order dispersion on both temporal and spectral characterizations of microresonator-based optical frequency combs. The moment method is utilized to study the temporal dynamics of intracavity solitons.
