Enhancement of polarization and related properties in heteroepitaxially constrained thin films of the ferroelectromagnet, BiFeO3, is reported. Structure analysis indicates that the crystal structure of film is monoclinic in contrast to bulk, which is rhombohedral. The films display a room-temperature spontaneous polarization (50 to 60 microcoulombs per square centimeter) almost an order of magn...

The authors summarize their experience with 174 patients with aplastic anaemia (AA) with particular reference to course, prognostic factors, conversion to other blood disorders, treatment and outcome. Aplastic anaemia was defined as pancytopenia and a hypocellular marrow at some time during the illness. Seven patients terminated with acute leukaemia, 8 developed haematological features of sider...

By using Rough Set Theory and the concept of attribute significance, the paper analyzes the approximate and detail component at different scales got by the wavelet transform of the original image, then adopts a knowledgereduction-based algorithm according to its importance in the signal classification, finally extracts the wavelet energy which is the most sensitive to signal characteristics in ...

This is a remarkable volume. Winner of the Lakatos award, given biennially for the book in the philosophy of science most highly regarded by an international committee, it is also crammed with formulas that will be of practical importance, as well as of interest, to epidemiologists, lawyers, economists, and other down-to-earth folk. This is not to say that it will be easy to read, for anyone, o...

Background: Like many viruses, bacteriophage X174 packages its I)NA genome into a procapsid that is assembled from structural intermediates and scaffolding proteins. The procapsid contains the structural proteins F, G and H, as well as the scaffolding proteins B and D. Provirions are formed by packaging of DNA together with the small internal J proteins, while losing at least some of the B scaf...

The genetic information of phix 174 genome (genes and intermediate segments) is analyzed in terms of its independent (D1 index) and dependent information (D2 and D3 Markovian indexes), as well as of its ability to generate secondary structure. Genes B and E, enclosed in A and D respectively, have: 1) values of D1 and D3 indexes closer to the theoretical random distribution curves than those of ...

Objective: To investigate the prevalence of traumatic events and life events in relation to posttraumatic stress disorder (PTSD). Method: In a Danish national representative sample of 390 eighth-grade students with a mean age of 14.5 years, 20 prevalent potential traumatizing and distressing events were described, along with the psychological impact of these events. Results: Eighty-seven percen...
