Externally detected vibroarthrographic (VAG) signals bear diagnostic information related to the roughness, softening, breakdown, or the state of lubrication of the articular cartilage surfaces of the knee joint. Analysis of VAG signals could provide quantitative indices for noninvasive diagnosis of articular cartilage breakdown and staging of(More)
Inhibitors of viral disassembly or RNA and protein synthesis, viral disassembly intermediates (infectious subviral particles, ISVP), binary ethylenimine-inactivated virions, and viral particles lacking genomic double-stranded (ds) RNA (empty particles) were used to assess the expression of interleukin-1beta (IL-1beta) mRNA in chicken (chIL-1beta)(More)
In this investigation we propose and experimentally demonstrate the self-protected and survivable time-division-multiplexed passive optical networks (PONs) in tree and ring topology architectures against fiber fault. Here, the feasible protection access architectures for the tree- and ring-based PONs are studied and discussed. Furthermore, different(More)
Taking into account the anisotropy of phase space in multiparticle production, a self-aane analysis of factorial moments was carried out on the NA22 data for + p and K + p collisions at 250 GeV/c. Within the transverse plane, the Hurst exponents measuring the anisotropy are consistent with unit value (i.e. no anisotropy). They are, however, only half that(More)

This paper describes a method for automatic reconstruction of concise polygonal curves from unorganized dense planar points. In reverse engineering, these planar points may be generated by slicing 3D data points and projecting them onto a plane. It is necessary to approximate these points by constructing 2D polygons, while keeping the shape error within a(More)
