66 results about "High variability" patented technology

A high genetic variation makes a healthy ecosystem or species. In the same way, a high genetic variability makes a healthy population. A higher variability means that the population is more able to respond to a change in their environment, and thus is more resistant to disease, climate change, competition from invading species, and so on.

Mitochondrial gene sequence for identifying Cordyceps sinensis and method

The invention provides a mitochondrial gene sequence for identifying authenticity and quality of Cordyceps sinensis and an operation method thereof. According to the method, differences of mitochondrial genes between ghostmoth and other lepidopteran insects are compared and thus high-variability areas can be searched. Specific primers of the ghostmoth are designed to obtain sequences of corresponding sections of mitochondria of host insects; if a nucleotide difference rate is less than 1-1.5 %, the insects are determined to be a same species but different individuals, and if the nucleotide difference rate is more than 6 %, the insects are determined to be a same genus but different species, thereby not only identifying whether to-be-detected samples are the Cordyceps sinensis formed with Hepialus larvae as the host insects, but also determining producing areas of the to-be-detected samples, and thus determining the authenticity and grades of the to-be-detected samples The method is simple in steps, easy to operate, and few in sample amount, and can minimize sample loss. According three pairs of the specific primers provided by the invention, the authenticity and the grades of the samples can be rapidly and conveniently detected through detecting whether the samples have same or similar nucleotide sequences as well as similarity of the nucleotide sequences.

Method and apparatus for chaosmetric brand protection with fluorescent taggant

A method and apparatus for establishing product items unique identity for purpose of anti-counterfeiting or anti-theft is disclosed. It employs a fluorescent taggant embedded in product item, template, digitally based Encoder and Decoder. The taggant comprising plurality of fluorescent entities which in turn may comprise such distinct geometric and spectral optical characteristics-attributes as relative locations, emission/absorption spectra, polarization degrees and post luminanc delay and duration times. Such uniqueness is determined by the presence of a combination of a wide variety of fluorescent materials used during the application. The set of fluorescent entities are result of a random process and form a product item's fingerprint. The said template is a particular digitized representation of a taggant. The Encoder may comprise a camera, LED array based activator, configured to follow a particular illumination sequence and computation unit. The said camera further comprises at least two polarizing filters and template generator and the respective controllers. The Decoder may comprise at least one camera identical to the of the Encoder, at least one template/taggant readers and a computation unit, which may be shared with the said Encoder. Product item identity is based on the fluorescent taggant uniqueness, with the later embedded into the product in a non separable way. After the extracted attribute values assiciated with the taggant, are digitized. Digitazing comprises mixing with chaff (spurious) patterns of the same format, error correction, transformation in a non invertible and compression and encryption. This forms a template, embedded in the product in a readable form. The decoding comprises feature extraction of taggant, reading template and decrypting, its content, error correction, decompression. Then the extracted and the decoding results are cross-matched in order to identify the product item. Irreproducibility of a plurality of fluorescent entities and high degree of security of its digital representation due to encryption, high variability of LED patterns and non-invertible transformation is a basis of a chaosmetric anti-counterfeiting solution disclosed in the present invention.
