    Description: An improved method for characterizing the magnetic anisotropy of films with cubic symmetry is described and is applied to an yttrium iron garnet (111) film. Analysis of the ferromagnetic resonance (FMR) spectra performed both in-plane and out-of-plane from 0.7 to 8 GHz yielded the magnetic anisotropy constants as well as the saturation magnetization. The field at which FMR is observed turns out to be quite sensitive to anisotropy constants (by more than a factor ten) in the low frequency (

    Description: The efficacy of pre- and postexposure treatment with the antiviral compound (R)-9-(2-phosphonylmethoxypropyl)adenine (PMPA) was tested against simian immunodeficiency virus (SIV) in macaques as a model for human immunodeficiency virus (HIV). PMPA was administered subcutaneously once daily beginning either 48 hours before, 4 hours after, or 24 hours after virus inoculation. Treatment continued for 4 weeks and the virologic, immunologic, and clinical status of the macaques was monitored for up to 56 weeks. PMPA prevented SIV infection in all macaques without toxicity, whereas all control macaques became infected. These results suggest a potential role for PMPA prophylaxis against early HIV infection in cases of known exposure.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Tsai, C C -- Follis, K E -- Sabo, A -- Beck, T W -- Grant, R F -- Bischofberger, N -- Benveniste, R E -- Black, R -- N01-AI-15120/AI/NIAID NIH HHS/ -- RR00166/RR/NCRR NIH HHS/ -- New York, N.Y. -- Science. 1995 Nov 17;270(5239):1197-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉University of Washington Regional Primate Research Center, Seattle 98195, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7502044" target="_blank"〉PubMed〈/a〉

    Description: Saharan silver ants, Cataglyphis bombycina, forage under extreme temperature conditions in the African desert. We show that the ants' conspicuous silvery appearance is created by a dense array of triangular hairs with two thermoregulatory effects. They enhance not only the reflectivity of the ant's body surface in the visible and near-infrared range of the spectrum, where solar radiation culminates, but also the emissivity of the ant in the mid-infrared. The latter effect enables the animals to efficiently dissipate heat back to the surroundings via blackbody radiation under full daylight conditions. This biological solution for a thermoregulatory problem may lead to the development of biomimetic coatings for passive radiative cooling of objects.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Shi, Norman Nan -- Tsai, Cheng-Chia -- Camino, Fernando -- Bernard, Gary D -- Yu, Nanfang -- Wehner, Rudiger -- New York, N.Y. -- Science. 2015 Jul 17;349(6245):298-301. doi: 10.1126/science.aab3564.

    Description: A novel type D retrovirus was isolated by cocultivation of explants of fibromatous tissue from a rhesus monkey (Macaca mulatta) with immunodeficiency and retroperitoneal fibromatosis. This type D virus, isolated from a macaque with simian acquired immunodeficiency syndrome (SAIDS-D/Washington), is exogenous and is partially related to the Mason-Pfizer and the langur monkey type D viruses. The SAiDS-D virus can be distinguished from all other primate retroviruses by antigenicity and molecular hybridization. Nucleic acid hybridization studies reveal that the origin of the SAIDS-D isolate may reside in Old World monkey (subfamily Colobinae) cellular DNA.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Stromberg, K -- Benveniste, R E -- Arthur, L O -- Rabin, H -- Giddens, W E Jr -- Ochs, H D -- Morton, W R -- Tsai, C C -- N01-CO-23909/CO/NCI NIH HHS/ -- N01-CO-23910/CO/NCI NIH HHS/ -- RR00166/RR/NCRR NIH HHS/ -- New York, N.Y. -- Science. 1984 Apr 20;224(4646):289-2.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6200929" target="_blank"〉PubMed〈/a〉

    Description: Phylogenetic analyses of Microstegium (Andropogoneae, Poaceae) and some other Andropogoneae species were conducted inferred from the ITS/5.8S sequences. As a result of this study, Microstegium is polyphyletic. There are two rather distant monophyletic clades, one with Microstegium nudum (type of Leptatherum), M. japonicum and M. somae, the other one with M. ciliatum, M. fauriei, M. geniculatum and M. vimineum (type of Microstegium). Therefore we feel justified to reinstate the genus Leptatherum and three new combinations, Leptatherum boreale, L. nudum and L. somae, are proposed.

    Description: Ceriops zippeliana, a member of the mangrove Rhizophoraceae, was first reported in 1849. It was considered to be a synonym of C. decandra, which is still widely accepted. We present morphological and molecular evidence to show that C. zippeliana is significantly distinct from C. decandra, and illustrations and an identification key to both species.

    Notes: The 4 3Σ+g, 3 3Πg, and 2 3Δg states of K2 have been studied by perturbation facilitated optical–optical double resonance spectroscopy for the first time. Molecular constants of those states are derived and compared with theoretical calculations. Varying the trial vibrational quantum numbers of these upper states, absolute vibrational quantum number assignments are obtained by comparison between the observed resolved fluorescence intensities and the calculated Franck–Condon factors. The Rydberg–Klein–Rees potential curves are constructed and compared with theoretical calculations. Finally, the observation of the lowest "dark'' vibrational levels of the b 3Πu state by resolved fluorescence from the 2 3Δg state confirmed the absolute vibrational numbering of this state and allowed refinement of the b 3Πu molecular constants. © 1995 American Institute of Physics.
