The dye "Stains-all" combines with calmodulin to yield a series of complex species whose absorption and circular dichroism spectra are sensitive to the presence of Ca2+ or Mg2+. At high dye:calmodulin ratios, the dominant complex formed is characterized by a strong absorption band at 600-650 nm, which is associated with a biphasic circular dichroism band. These spectral features are abolished i...

Transmission Mueller-matrix spectroscopic ellipsometry is applied to the cuticle of the beetle Cetonia aurata in the spectral range 300-1000 nm. The cuticle is optically reciprocal and exhibits circular Bragg filter features for green light. By using differential decomposition of the Mueller matrix, the circular and linear birefringence as well as dichroism of the beetle cuticle are quantified....

In this paper, we propose a fast combined separability filter, which can selectively detect circular features such as pupils and nostrils in an image of the human face. The proposed filter is designed as a combination of multiple rectangle separability filters so that it can achieve high-speed processing and high positioning accuracy at the same time. The evaluation experiments using synthetic ...

We compare the Fresnel diffraction pattern of a thin circular disk with that of a square obstacle, specifically evaluating the on-axis field strength. Photographs of the diffraction patterns reveal some curious features for the square obstacle. Second, the precise electric and magnetic fields behind a conducting circular disk are evaluated without invoking the Fresnel approximation and contrast...

We consider a new kind of computational device like Turing machine, so-called circular Post machines with a circular tape and moving in one direction only, introduced recently by the second and the third authors. Using 2-tag systems we construct new nine small universal machines of this kind.

Porcine stool-associated circular virus 5 (PoSCV5) was detected in the feces of a pig with diarrhea. The complete 3,062-nucleotide genome contains two bidirectionally transcribed open reading frames (ORFs). Phylogenetic analysis of the deduced replication initiator protein (Rep) places PoSCV5 alone on a deep branch among the small circular Rep-encoding single-stranded DNA viruses.

A neural network model based on the anatomy and physiology of the cerebellum is presented that can generate both simple and complex predictive pursuit, while also responding in a feedback mode to visual perturbations from an ongoing trajectory. The model allows the prediction of complex movements by adding two features that are not present in other pursuit models: an array of inputs distributed...
