Centrifugal separation of antiprotons and electrons is observed, the first such demonstration with particles that cannot be laser cooled or optically imaged. The spatial separation takes place during the electron cooling of trapped antiprotons, the only method available to produce cryogenic antiprotons for precision tests of fundamental symmetries and for cold antihydrogen studies. The centrifu...
A report is given on results obtained in the examination of desiccated coconut from Ceylon and the Philippines using two or three media in parallel, the aim being to investigate the efficacy of the enrichment medium introduced by Rappaport, Konforti, and Navon (1956). Although the claims of Rappaport et al. related only to examination of faeces the Rappaport enrichment medium has been found to ...
Abstract Inflammatory demyelinating diseases of the central nervous system (CNS) include clinically and pathologically distinct disorders. Myelin oligodendrocyte glycoprotein-associated disease (MOGAD) is a recently characterized antibody-mediated inflammatory disorder CNS with clinical presentations which optic neuritis, transverse myelitis, acute disseminated encephalomyelitis. The heterogeno...
Cultivated tomato (Solanum lycopersicum) is susceptible to late blight, a major disease caused by Phytophthora infestans, but quantitative resistance exists in the wild tomato species S. habrochaites. Previously, we mapped several quantitative trait loci (QTL) from S. habrochaites and then introgressed each individually into S. lycopersicum. Near-isogenic lines (NILs) were developed, each conta...
Mediterranean orchids of the subtribe Orchidinae are highly diverse and display a range of fascinating pollination strategies. Based on observations that orchid-pollinator relationships are often highly specialized and species specific, Darwin and others have argued that selection for different pollinators has been the driving force behind the evolutionary diversification of orchids. This may b...
Dynamic dipolar interactions between spin wave eigenmodes of closely spaced nanomagnets determine the collective behavior of magnonic and spintronic metamaterials and devices. However, dynamic dipolar interactions are difficult to quantify since their effects must be disentangled from those of static dipolar interactions and variations in the shape, size, and magnetic properties of the nanomagn...
We investigate order-theoretic properties of the nonstandard real line, by isolating the basic order-types involved, and the possible relations among them. We focus on order-isomorphisms between the infinitesimals, the infinites, and the whole hyperreal line. We also compute the main cardinal invariants of the order-topology of the nonstandard real line.
An enrichment technique was developed whereby azotophage could readily be isolated after inoculation of soil sites with Azotobacter vinelandii.
introduction amblyopia is a leading cause of visual impairment in both childhood and adult populations. our aim in this study was to assess the epidemiological characteristics of the amblyopia screening program in iran. materials and methods a cross-sectional study was done on a randomly selected sample of 4,636 iranian children who were referred to screening program in 2013 were participated i...
background in 1996, donovan and colleagues represented a scoring system for better prediction of hirschsprung disease (hd). objectives our objective was to devise another scoring system that uses a checklist of radiologic and clinical signs to determine the probability of hd in suspicious patients. patients and methods in a diagnostic accuracy study, 55 children with clinical manifestations of ...
