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...

The inability of computing humanists to break into the mainstream of literary critical scholarship may be attributed to the prevalence of scientific methodologies and metaphors in humanities computing research—methodologies and metaphors that are wholly foreign not only the language of literary criticism, but to its entire purpose. Breaking out of this unfortunate misalignment entails reaching ...

The structure of the single-stranded DNA phage ~X174 has been determined to 3.4/k resolution. The crystal space group was P2~ with one icosahedral particle per asymmetric unit, giving 60-fold noncrystallographic redundancy. Oscillation diffraction photographs were collected using synchrotron radiation at various wavelengths. The particle orientations in the unit cell were determined with a rota...

Direct analysis of unassembled genomic data could greatly increase the power of short read DNA sequencing technologies and allow comparative genomics of organisms without a completed reference available. Here, we compare 174 chloroplasts by analyzing the taxanomic distribution of short kmers across genomes [1]. We then assemble de novo contigs centered on informative variation. The localized de...

BACKGROUND Experimental studies have shown that induction of hypothermia before reperfusion of acute coronary occlusion reduces infarct size. Previous clinical studies, however, have not been able to show this effect, which is believed to be mainly because therapeutic temperature was not reached before reperfusion in the majority of the patients. We aimed to evaluate the safety and feasibility ...
