The faunistic and ecological study of the helminthfaunas of mammals in Azorean islands is considered. 103 rodents (Rattus rattus L., 1758 and Mus musculus L., 1758) 9 insectivores (Erinaceus europaeus L., 1758) and 19 lagomorphs (Oryctolagus cuniculus L., 1758) were analysed. The hosts been captured in several biotopes of thre islands (São Miguel, Terceira and Flores). 27 helminth species were detected (3 Digenea Trematoda, 5 Cestoda, 18 Nematoda and 1 Acantocephala). All hosts species show high prevalences and no significant differences were found between different islands. The helminthfaunas show typical features of a young island parasitofaunas. [less ▲]

We are in an era where visual photometry is under question. The greatest asset of existing visual data is that they have been collected over a very long time baseline (in principle over thousands of years). But there are reasons for which modern visual estimates are not comparable to ancient ones. [less ▲]

Estimating the pose of the observed person is crucial for a large variety of applications including home entertainment, man-machine interaction, video surveillance, etc. Often, only a single side view is available, but authors claim that it is possible to derive the pose despite that humans evolve in a 3D environment. In addition, to decrease the sensitivity to color and texture, it is preferable to rely only on the silhouette to recover the pose. Under these conditions, we show that there is an intrinsic limitation: at least two poses correspond to the observed silhouette. We discuss this intrinsic limitation in details in this short paper. To our knowledge, this issue has been overlooked by authors in the past. We observe that this limitation has an impact on the way previous reported results should be interpreted, and it has clearly to be taken into account for designing new methods. [less ▲]

Maximally entangled states can serve as a useful resource in many different contexts. It is therefore important to identify those states. Here we are interested in the identification of maximally entangled states in the symmetric subspace of an N-qubit system. By maximally entangled states, we refer to symmetric states characterized by a one qubit reduced density matrix proportional to the identity. These states maximise various entanglement measures [1] such as von Neumann and Meyer-Wallach entropy and are unique up to LU in their SLOCC class [2]. We identify and characterize all maximally entangled symmetric states up to 4 qubits. We provide general conditions for a symmetric state with an arbitrary number of qubits to be maximally entangled and identify families of SLOCC classes which do not contain any maximally entangled states.

Measuring a path performance according to one or several metrics, such as delay or bandwidth, is becoming more and more pop- ular for applications. However, constantly probing the network is not suitable. To make measurements more scalable, the notion of clustering has emerged. In this paper, we demonstrate that clustering can limit the measurement overhead in such a context without loosing too much accuracy. We first explain that measurement reduction can be observed when vantage points collaborate and use clustering to estimate path performance. We then show, with real traces, how effective is the overhead reduction and what is the impact in term of measurement accuracy. [less ▲]

When preparing and characterizing ordered organic layers, knowledge of the structure of the ultra-thin fihns is often missing or difficult to gather. For different self-assembled layers of the thiol and carboxylic acid families, we show that this valuable type of information is obtainable with X-ray photoelectron spectroscopy (XPS) and high-resolution electron energyqoss spectroscopy (HREELS). Indeed, information on the film order and superficial composition is available through analysis of the core-level peak positions and widths (in XPS), and through study of the elastic peak width and angular distribution and analysis of the material excitation function (in HREELS). However, [or some insight into the crystallinity of the layer and intermolecular interactions, infrared spectroscopy in the grazing-angle absorption--reflection mode (IRASI appears to be complementary [less ▲]
