    Notes:
    Structure changes in the Hf–Al–Ni–Pd metallic glass on heating have been studied by x-ray diffraction, transmission electron microscopy, and differential scanning calorimetry. It has been found that the first stage of the devitrification process is related to the precipitation of fine particles of an icosahedral phase from about 5 to 15 nm in size. A direct evidence of the formation of the icosahedral phase has been done using nanobeam diffraction in transmission electron microscope. © 2000 American Institute of Physics.

    Notes:
    Although many Viola species are grown as ornamentals, no information on molecular markers is available for the classification and breeding of Viola. Random amplified polymorphic DNA (RAPD) analysis was applied to identify series-specific molecular markers from the series Pinnatae, Chinensis, and Variegatae of Viola species in the subsection Patellares. We report eight RAPD markers which can be used to distinguish three different series of Viola species based on morphological characters. The eight RAPD markers we identified could be useful to classify Viola species and to assist the hybrid breeding of new varieties.

    Notes:
    While the enormous clinical and psychosocial importance of pruritus in many areas of medicine and the detrimental effects of chronic ‘itch’ on the quality of life of an affected individual are widely appreciated, the complexity of this sensation is still often grossly underestimated. The current Controversies feature highlights this complexity by portraying pruritus as a truly interdisciplinary problem at the crossroads of neurophysiology, neuroimmunology, neuropharmacology, protease research, internal medicine, and dermatology, which is combated most successfully if one keeps the multilayered nature of ‘itch’ in mind and adopts a holistic treatment approach – beyond the customary, frequently frustrane monotherapy with histamine receptor antagonists. In view of the often unsatisfactory, unidimensional, and altogether rather crude standard instruments for pruritus management that we still tend to use in clinical practice today, an interdisciplinary team of pruritus experts here critically examines recent progress in pruritus research that future itch management must take into consideration. Focusing on new insights into the neuroimmunological, neuroendocrine, and neurophysiological bases of pruritus, and discussing available neuropharmacological tools, specific research avenues are highlighted, whose pursuit promises to lead to novel, and hopefully more effective, forms of pruritus management.

    Abstract. In the graph-searching problem, initially a graph with all the edges contaminated is presented. The objective is to obtain a state of the graph in which all the edges are simultaneously cleared by using the least number of searchers. Two variations of the graph-searching problem are considered. One is edge searching, in which an edge is cleared by moving a searcher along this edge, and the other is node searching, in which an edge is cleared by concurrently having searchers on both of its two endpoints. We present a uniform approach to solve the above two variations on several subclasses of chordal graphs. For edge searching, we give an O(mn 2 ) -time algorithm on split graphs (i.e., 1-starlike graphs), an O(m+n) -time algorithm on interval graphs, and an O(mn k ) -time algorithm on k -starlike graphs (a generalization of split graphs), for a fixed k\geq 2 , where m and n are the numbers of edges and vertices in the input graph, respectively. There is no polynomial algorithm known previously for any of the above problems. In addition, we also show that the edge-searching problem remains NP-complete on chordal graphs. For node searching, we give an O(mn k ) -time algorithm on k -starlike graphs for a fixed k \geq 1 . This result implies that the pathwidth problem on k -starlike graphs can also be solved in this time bound which greatly improves the previous results.

    Abstract Given a set ofn points on the plane, the rectilinearm-center problem is to findn rectilinear squares covering all thesen points such that the maximum side length of these squares is minimized. In this paper we prove that there is no polynomial-time algorithm with an error ratio ɛ 〈 2 for the rectilinearm-center problem unless NP = P. A polynomial-time approximation algorithm with an error ratio of 2 is also proposed.

    [Auszug] In situ measurements of stratospheric sulphate aerosol, reactive nitrogen and chlorine concentrations at middle latitudes confirm the importance of aerosol surface reactions that convert active nitrogen to a less active, reservoir form. This makes mid-latitude stratospheric ozone less vulnerable to ...
