A polyaxial bone screw assembly includes a threaded shank body having an upper portion with a capture structure thereon, a retaining and articulating structure, a compression structure and a receiver for holding the capture structure, retaining and articulating structure, compression structure and a rod. The receiver includes arms that define a channel for receiving the rod. The arms have inner surfaces with a discontinuous flange form thereon for mating with a cooperating continuous flange form of a closure structure for capturing the rod within the receiver. The shank capture structure and the retaining and articulating structure are threadably attached and secured to one another with a buttress stop. In operation, the compression structure is disposed within the receiver between the shank upper portion and a rod but presses only upon the retaining and articulating structure. The retaining and articulating structure has an external substantially spherical surface that mates with an internal surface of the receiver, providing a ball joint, enabling the receiver to be disposed at numerous angles relative to the shank body. The shank upper portion includes a tool engagement formation for driving the shank body into bone.

The flexible storage bag includes overlaying first and second sidewalls defining an internal volume that can be accessed from an open top edge. To evacuate air from the internal volume after the open top edge has been closed, the bag includes a one-way valve element attached to the first sidewall and communicating with the internal volume. To prevent the one-way valve element from becoming clogged by the opposing second sidewall, the bag also includes a clearance member that maintains at least a partial clearance between the first and second sidewalls proximate the valve element. The clearance member can take many forms such as a textured portion on the second sidewall that includes evacuation passages which provide air in the internal volume access to the valve element, a permeable element covering the valve element, and a rigid or compressible structure that spaces the second sidewall from the valve element.

The invention relates to a video compressing and encoding method with an alpha transparent channel, comprising the following steps of: inverting the acquired video image to the image in the format of RGB or YUV4:4:4/YUV4:2:2/YUV4:2:0; compressing the acquired data in the alpha transparent channel in a no-damage mode; encoding and compressing video data for the video image in the specific format according to the frame format of MPEG-2 I and saving the compressed data in the alpha transparent channel in the compressed data structure of the video image. The method realizes the encoding of a specific video picture, can use a standard MPEG2 encoder for encoding, and effectively reduces video bitrate when ensuring the high quality of the video so as to realize the video data encoding with high quality, high efficiency and low cost. Because the data of the alpha transparent channel and the compressed data of the video image are saved in the same file, the video compressing and encoding method not only simplifies the process of processing the image at the later period and the information sharing between file management and a program, but also reserves the original video which is not added with the data of the alpha transparent channel.

A method and a parallel-computing system of mapping sequencing reads is provided. The method preprocesses a reference genome to construct a compression structure of the reference genome, an index array and a block address array; the index array stores the index values of all sorted subsequences on the reference genome; the block address array stores the positions of a portion of the elements in the index array; the parameters involved in the mapping method are selected based on the statistical characteristics of the reference genome, the statistical quality information of sequencing reads and the polymorphism rates of the target species from which the sequencing reads are generated. Based on the structures constructed in the preprocessing stage, each sequencing read is mapped to the reference genome by anchoring on the genome by a certain single perfect match prefix seed, alignment extension based on the auto-match function method, and statistical assessment.

Compressed waveform data structure is proposed which is suited for segmentation of a plurality of samples of compressed waveform data into a plurality of frames and subsequent storage of each of the frames. The number of bits per sample of the compressed waveform data is variable between the frames, but uniform, i.e. the same among all of the samples, within each of the frames. Each of the frames has a same data storage size. Each of the frames includes, in a predetermined layout, an auxiliary information area for storing auxiliary information that includes compression-related information to be used for decompressing the compressed waveform data, and a data area for storing a plurality of samples of the compressed waveform data of the frame with each of the samples comprising a same number of bits. Thus, respective start positions of the frames and compressed waveform data in a memory can be fixed at predetermined positions common to the frames, so that readout control can be performed with ease.

A shockproof spindle includes a spindle inserted into an elastomer, a compressible structure, and a sleeve, a hollow cylinder, sequentially. The sleeve caps the elastomer while the elastomer presses on the top of the base fixed under the spindle. The ball keeps contact the chute of the spindle and the chute of the sleeve. In addition to all of the above, the elastomer held between the base and the sleeve absorbs the impact when a tool installed on the end of the spindle is shocked against the workpiece during operation process. Since the spindle works smoothly owing to the effect of the elastomer, the operators work more easily, and the damage or destruction of assembly precision, made by the impact, of the parts in the electric tool is avoided.
