In these notes we investigate the ring of real polynomials in four variables, which are invariant under the action of the reflection groups [3, 4, 3] and [3, 3, 5]. It is well known that they are rationally generated in degree 2,6,8,12 and 2,12,20,30. We give a different proof of this fact by giving explicit equations for the generating polynomials. 0 Introduction There are four groups generate...

The American brine shrimp Artemia franciscana is important in aquaculture and has become invasive other continents, aided by dispersal via waterbirds. However, little known about processes underlying its genetic diversity population structure natural habitat North America. These processes, including local adaptation, are pivotal drivers of species distribution community structure, therefore cen...

Parasites, in particular trematodes (Platyhelminthes: Digenea), play major roles in the population dynamics and community structure of invertebrates on soft-sediment mudflats. Here, we provide a list of the 20 trematode species currently known to infect molluscs, crustaceans and polychaetes from Otago Harbour (New Zealand) soft-sediment intertidal areas, as well as information on their transmis...

Oriented soft magnetic hcp-Co1 - x Ir x films with a fixed thickness of 120 nm were fabricated. All prepared films exhibit soft magnetic properties but various magnetocrystalline anisotropies with the variation of Ir content. The measured data shows that diverse domain structures including the Néel wall, Bloch wall, and stripe domains present in a fixed film thickness. It is singular for the si...

The main aim of DNA barcoding is to establish a shared community resource of DNA sequences that can be used for organismal identification and taxonomic clarification. This approach was successfully pioneered in animals using a portion of the cytochrome oxidase 1 (CO1) mitochondrial gene. In plants, establishing a standardized DNA barcoding system has been more challenging. In this paper, we rev...

Complete nucleotide sequences of the mitochondrial cytochrome b (Cytb) and cytochrome c oxidase subunit 1 (CO1) genes from various isolates of Taenia solium were examined. Eleven isolates were analyzed; two isolates from China, two isolates from Indonesia, one isolate each from India, Thailand, Mexico, Ecuador, Peru, Mozambique and Tanzania. In both genes, two isolates from Indonesia shared the...

The temperature stability of field induced uniaxial anisotropy KU was investigated by thermomagnetic treatments of Co1−xFex 89Zr7B4 amorphous ribbons after field annealing below and above the crystallization temperature. We conclude: 1 Field annealing treatments are necessary to properly investigate the temperature stability of KU, 2 KU of field crystallized alloys exhibit improved temperature ...

We present a detailed DFT-based electronic structure calculation of Co1–xFexS2, a model ferromagnetic system with tunable spin polarization, P. It is shown that the position of the Fermi level and the spin polarization can be controlled by x, the Fe concentration. We predict that for x = 0 the system has predominantly minority carriers corresponding to P = –75%. Upon doping to x = 0.25, the sys...
