Introduction There is a growing body of MRI research on the effects of abnormal levels of iron in the brain [1], with several different methods proposed to quantify iron loading, e.g. transverse relaxation [2]; phase [3] and Magnetic Field Correlation (MFC) mapping [4]. Validation of each technique with a phantom of known iron concentrations is useful for determining the sensitivity of differen...

Swift foxes (Vulpes velox) were once distributed across most of the shortgrass prairie of North America. The arrival of settlers and the concurrent loss of habitat, trapping, incidental poisoning, and shooting brought about a decline in its numbers until the swift fox remained only in the southern part of its historic range. A current understanding of swift fox population ecology is important t...

Standard knowledge representa t ion languages are se r i ous l y lack ing an e x p l i c i t formal semantic s p e c i f i c a t i o n .

It appears that coyote (Canrs latrans) abundance 1s determined pr~mal-~ly b avallabil~ty of food (prey) as mediated through social dominance h~erarchles and a telritol-ial land tenure system. This is reflected in rates of reproduction, dispersal, and mo~tality, with survival ofjuveniles a major factor Suggestions for a new gencrat~on of simulation niodels to explore coyote population funct~ons ...

Single-mode Ge28Sb12Se60 strip waveguides, fabricated with thermal evaporation and lift-off, were demonstrated at 1.03 μm. The linear and nonlinear optical properties of these waveguides were shown to be similar to bulk samples, with differences attributed to small variations in composition of ~4 atomic % or less. From z-scan measurements at 1.03 μm using circularly polarized, ~200 fs pulses at...

It is our great pleasure to introduce this second edition of the focus issue on phase-change and ovonic materials. This special aims summarize recent progress in rapidly developing field materials their numerous applications. provides a snapshot state-of-the-art, both experimental theoretical, for experienced young researchers interested subject area. Since its very first 2019, we expect publis...

Once again, it is our great pleasure to continue the E\PCOS tradition by presenting this fourth edition of special issue on Phase-Change and Ovonic Materials that published each year as part European Symposium Sciences (E\PCOS). We have admit 2022 had a spirit marked long-awaited return face-to-face on-site symposium after two-year hiatus due Covid crisis. Last September, was most successful in...

We report the synthesis of free-standing two-dimensional semiconductor zinc oxide (ZnO) nanomembranes (NMs) using a bottomup approach, i.e., nanomembranes grown from the faceted sidewalls of horizontally oriented ZnO nanowires (NWs). The ZnO NMs were synthesized on r-plane sapphire substrates utilizing high purity ZnO powder and graphite mixture and oxygen as source materials and argon (Ar) as ...
