A new type of oscillon that arises from interaction between subcritical Turing and wave instabilities is found in a system of reaction-diffusion equations. These oscillons can be induced resonantly by localized external periodic perturbations. This phenomenon may be useful for frequency selection and/or information processing.

With minimal sleight of hand, it is possible to transform the recent growth experience of the People’s Republic of China from the extraordinary into the mundane. Systematic understatement of inflation by enterprises accounts for 2.5 percent growth per year in the nonagricultural economy during the first two decades of the reform period (1978–98). The usual suspects (i.e., rising participation r...

We demonstrate experimentally and theoretically (both analytically and numerically) a new type of spatial soliton: a rotating "propeller" soliton. This is a composite soliton made of a rotating dipole component jointly trapped with a bell-shaped component. We observe as much as 239 degrees of rotation over 13 mm of propagation (6.5 diffraction lengths).

The Virtual Collection is a project by ZOOM Children's Museum, Vienna. It is a part of the new Media Lab, which will be opened in September 2000. The collection comprises objects of popular children's culture a field, which has, to date, been neglected in digital archiving. International cooperations with other Institutions are being targeted to achieve most possible variety. The collection wil...

We report the first observation of the polar phase of superfluid (3)He. This phase appears in (3)He confined in a new type of aerogel with a nearly parallel arrangement of strands which play the role of ordered impurities. Our experiments qualitatively agree with theoretical predictions and suggest that in other systems with unconventional Cooper pairing (e.g., in unconventional superconductors...

Novel methods for identifying a new type of DNA latent periodicity, called latent profile periodicity or latent profility, are used to search for periodic structures in genes. These methods reveal two distinct levels of organization of genetic information encoding. It is shown that latent profility in genes may correlate with specific structural features of their encoded proteins.

This paper reviews recent progress on nonreciprocal metamaterials, especially with the nonreciprocity in the phase characteristics of transmission coefficients, and their applications to antennas. The nonreciprocal metamaterials are implemented into leaky wave antennas, new type of traveling wave resonators, and resonant-type beam-steering antennas.

We suggest a new type of optimized composite filter, i.e., the asymmetric segmented phase-only filter (ASPOF), for improving the effectiveness of a VanderLugt correlator (VLC) when used for face identification. Basically, it consists in merging several reference images after application of a specific spectral optimization method. After segmentation of the spectral filter plane to several areas,...
