摘要:
An area of research in the field of bioinformatics deals with the identification of similarities within one, or between two DNA sequences. Current techniques are quite slow and many matches are missed. The invention provides a faster and more sensitive solution, by using “optimised spaced seeds” to perform these biological sequence homology searches. Various techniques are shown for identifying seeds which are optimized to improve the sensitivity or speed of the searching. In the preferred embodiment, optimized spaced seeds are determined by the parameters of the search and independent of the actual databases being searched (for example, using the length and weight of the spaced seed, as well as the probability of a hit in a similar region). Thus, these optimized seeds can be stored in libraries which are accessed as required.

The present invention provides a new type of laterally container, which is composed of bottom platform, corner posts, front walls and end walls and container top. At the container top, there is a middle top beam, one or more top beams mounted symmetrically at both sides of the middle top beam. The other ends of the middle top are linked to the lateral beams of the container body. One spacing wall is mounted along the longitudinal central line of the bottom platform, the lower end of the spacing wall is linked to the bottom platform and the upper end of the spacing wall is linked to the container top, and its front and back ends linked respectively to the front and end walls. The platform is mounted aslant. This structure has advantages of high strength, which can prevent the distortion of the container body, and two individual spaces for containing goods that can also protect the goods from waggling during transportation. This type of container has simple construction and low costs, and it can be loaded and unloaded conveniently.
