Testate amoebae are informative about palaeoecological conditions, but the methods generally used for their analyses in lake sediments differ from those used for their analyses in peats, making comparisons difficult. This study examines how filter mesh siz ...
We identify a route towards achieving a negative index of refraction at optical frequencies based on coupling between plasmonic waveguides that support backwards waves. We show how modal symmetry can be exploited in metal-dielectric waveguide pairs to achi ...
Refractive index changes up to 2.5 × 10-3 were demonstrated in H2-loaded germanium free Bi-Al-doped silica fibers using both ArF excimer and cw-Ar+-244 nm lasers. Tensile stress changes indicate clear contribution of compaction to the total index change. ...
Events occurring in a city, such as car accidents, attacks on the security or activities locations are channelled in the urban network. The goal of this report is to provide a GIS tool able to compute densities and diversities in a network space rather tha ...
Using radiative reflectance as the discriminatory functional trait, we find scale-free signatures of local functional diversity density of vegetation in river basins, implying a high likelihood of locations with very high diversity relative to the overall ...
The genetic diversity of the world's livestock populations is decreasing, both within and across breeds. A wide variety of factors has contributed to the loss, replacement or genetic dilution of many local breeds. Genetic variability within the more common ...
The mitochondrial Cytochrome Oxidase Subunit 1 gene (COI) has been promoted as an ideal “DNA barcode” for animal species and other groups of eukaryotes. However, the utility of the COI marker for species level discrimination and for phylogenetic analyses h ...
T lymphocytes (T cells) are key components of the adaptive immune system. These cells are able to recognize an enormous variety of pathogens thanks to the great specificity of their trans-membrane proteins, the T cell receptors (TCRs). TCR diversity is cre ...
Mean index changes up to 2.2 × 10-3 were demonstrated in hydrogen loaded germanium free Bi-Al-doped silica fibers. Tensile stress changes indicate a contribution of compaction to the total index change. ...
This paper presents the importance of microstructural studies for understanding concrete durability. Three examples-sulfate attack; alkali silica reaction and bacteriogenic corrosion in sewers arc used to illustrate the pitfalls which can arise from conven ...
