    摘要: Provided are compounds and methods useful for sealing air leaks in the thoracic cavity. Compounds and compositions of the invention comprise certain amphiphilic peptides, 8-200 amino acid residues long, that self-assemble spontaneously to form a gel in the presence of physiological pH and/or in the presence of a cation. In one embodiment, the peptide comprises a repeated sequence arginine-alanine-aspartic acid-alanine (RADA). Methods of the invention include a method of occluding a pulmonary air leak in a subject, comprising applying a compound of the invention to the site of a pulmonary air leak. The compounds and methods of the invention can be combined with other agents useful to treat cancer, inflammation, or infection.

    摘要: The present invention relates to a data processing apparatus, a data processing method and a program which can improve the tolerance of code bits of an LDPC code to errors.Where two or more bits of an LDPC (Low Density Parity Check) code are set as one symbol and are mapped to 214 or 216 signal points, a column twist interleaver 24 carries out, as a re-arrangement process for re-arranging code bits of an LDPC code such that a plurality of code bits corresponding to the value 1 included in one arbitrary row of a parity check matrix are not included in one symbol, column twist interleave of changing the writing starting position when code bits are written in a column direction of a memory for each column of the memory. The present invention can be applied, for example, to a transmission apparatus for transmitting an LDPC code.

    摘要: The present invention relates to a data processing apparatus and a data processing method which can improve the tolerance to errors of data. A demultiplexer 25 replaces, in accordance with an allocation rule for allocating code bits of an LDPC code to symbol bits representative of symbols, mb bits from among the code bits and sets the code bits after the replacement as symbol bits of b symbols. For example, when m is 12 and b is 1, where the i+1th bits from the most significant bit of the 12×1 code bits and the 12×1 symbol bits of one symbol are represented as bits bi and yi, replacement for allocating, for example, b0 to y8, b1 to y0, b2 to y6, b3 to y1, b4 to y4, b5 to y5, b6 to y2, b7 to y3, b8 to y7, b9 to y10, b10 to y11 and b11 to y9 is carried out. The present invention can be applied, for example, to a transmission system for transmitting an LDPC code and so forth.

    摘要: A data processing apparatus, a data processing method, an encoding apparatus and an encoding method which can be applied, for example, to a transmission system for transmitting an LDPC code and so forth, and which can improve the tolerance to errors. Of an LDPC code which is prescribed in the DVB-S.2 and has a code length of 64,800 and an encoding rate of 2/3, mb code bits are replaced, and the code bits after the replacement become symbol bits of b symbols. When m is 8 and b is 2, where the i+1th bit from the most significant bit of 8×2 code bits and 8×2 symbol bits of two successive symbols are represented by bi and yi, respectively, replacement of allocating b0 to y15, b1 to y7, b2 to y1, b3 to y5, b4 to y6, b5 to y13, b6 to y11, b7 to y9, b8 to y8, b9 to y14, b10 to y12, b11 to y3, b12 to y0, b13 to y10, b14 to y4 and b15 to y2.
