    • This specification describes technologies relating to multi core processing for parallel speech-to-text processing. In some implementations, a computer-implemented method is provided that includes the actions of receiving an audio file; analyzing the audio file to identify portions of the audio file as corresponding to one or more audio types; generating a time-ordered classification of the identified portions, the time-ordered classification indicating the one or more audio types and position within the audio file of each portion; generating a queue using the time-ordered classification, the queue including a plurality of jobs where each job includes one or more identifiers of a portion of the audio file classified as belonging to the one or more speech types; distributing the jobs in the queue to a plurality of processors; performing speech-to-text processing on each portion to generate a corresponding text file; and merging the corresponding text files to generate a transcription file.

    • A document analyzer receives a collection of text-based terms associated with a document. The document analyzer performs a statistical analysis on the text-based terms to identify a distribution of where the text-based terms appear in the document and relative frequency indicating how often the text-based terms appear in the document. The document analyzer utilizes the distribution and relative frequency information derived from the statistical analysis to rank multiple themes associated with the document. For example, a received listing of multiple themes may not be presented in any useful order, although it can be assumed that the themes in the listing are present in the document. Based on application of distribution and relative frequency information derived from the analysis, the document analyzer can identify which themes are most relevant to the document as a whole and/or which of themes correspond to different portions (e.g., pages or sections) of the document.
    • 文档分析器接收与文档相关联的基于文本的术语的集合。 文档分析器对基于文本的术语进行统计分析,以识别基于文本的术语在文档中出现的位置的分布,以及指示基于文本的术语出现在文档中的频率的相对频率。 文档分析器利用从统计分析得到的分布和相对频率信息来排列与文档相关联的多个主题。 例如,收到的多个主题的列表可能不会以任何有用的顺序呈现,尽管可以假设列表中的主题存在于文档中。 基于从分析得到的分布和相对频率信息的应用,文档分析器可以识别哪些主题与整个文档最相关,和/或哪个主题对应于文档的不同部分(例如,页面或部分) 。

    • A method and a system is provided to process data. For example, the method and system may be used to store (e.g., archive) documents. In an embodiment, the method comprises receiving a quantum of data and creating n data pieces of size s from the quantum of data. The method may comprise generating k random numbers of size s, wherein k defines a minimum number of processed data pieces required to reconstruct the quantum of data, and performing polynomial arithmetic modulo prime on the n data pieces. The polynomial arithmetic may utilize polynomial of order k and the prime may be selected based on a bit processing capability of a processor used to process the data. The prime may be 28+1 when the bit processing capability of a processor is 16 bits and 216+1 when the bit processing capability of a processor is 32 bits.

    • A target is bombarded with high energy particles to generate a radioisotope, and the radioisotope is preferably extracted by one of the following: combusting the target in oxygen, stopping the bombardment and heating the target, or heating the target by induction. Bombardment may take place through a windowless path, and the radioisotope may be used for PET. The particles used may be deuterons or protons, and .sup.13 N may be generated. .sup.11 C may also be generated from either .sup.11 B or .sup.10 B using protons or deuterons. Combustion may be performed by induction heating and may be controlled by the quantity of oxygen available or the temperature. Combustion may be primarily confined to a surface layer and the target may be reused. The beam energy may be 2.2 MeV or less. Another general aspect includes trapping the oxides of .sup.13 N in a trap. The oxides may be converted into .sup.13 N-Ammonia, and this conversion may take place in the trap, which trap may comprise silica gel and sodium hydroxide and may also contain a reducing agent such as Raney-Nickel.
