摘要： In a corpus of scientific articles such as a digital library, documents are connected by citations and one document plays two different roles in the corpus: document itself and a citation of other documents. A Bernoulli Process Topic (BPT) model is provided which models the corpus at two levels: document level and citation level. In the BPT model, each document has two different representations in the latent topic space associated with its roles. Moreover, the multi-level hierarchical structure of the citation network is captured by a generative process involving a Bernoulli process. The distribution parameters of the BPT model are estimated by a variational approximation approach.

摘要： Semi-supervised learning plays an important role in machine learning and data mining. The semi-supervised learning problem is approached by developing semiparametric regularization, which attempts to discover the marginal distribution of the data to learn the parametric function through exploiting the geometric distribution of the data. This learned parametric function can then be incorporated into the supervised learning on the available labeled data as the prior knowledge. A semi-supervised learning approach is provided which incorporates the unlabeled data into the supervised learning by a parametric function learned from the whole data including the labeled and unlabeled data. The parametric function reflects the geometric structure of the marginal distribution of the data. Furthermore, the proposed approach which naturally extends to the out-of-sample data is an inductive learning method in nature.

摘要： The present invention provides a novel method for specifically isolating and separating large segments of genomic DNA that can subsequently be used to determine a genomic haplotype. The invention relies on using a solid phase having a flat surface arrayed with oligonucleotides designed to specifically hybridize to each particular haplotype of an individual sample, e.g., oligonucleotides designed to specifically hybridize with each of the two HLA-B haplotypes, HLA-A, HLA-C, HLA-DR, HLA-DQ, and the like. The genomic DNA is contacted and hybridized to the arrayed oligonucleotides to form a genomic DNA/oligonucleotide complex. The excess genomic DNA is washed away and the haplotype separated genomic DNA is denatured from the oligonucleotide probe and collected. The method of the present invention allows for the separation of genomic DNA fragments of between approximately 2 to about 4 megabases (Mb). Separation of the haplotypes of large genomic DNA fragments allows for linkage analysis of other HLA alleles and polymorphisms, microsatellite, SNPs, and the like across a large span of the HLA region, including HLA-A, -B, -C, and HLA-DRB1 regions. This linkage analysis is particularly useful when HLA typing for an individual with limited family HLA typing available.

摘要： Methods and devices are disclosed for transferring a first liquid into a second liquid through a wick material. Said wick material preferentially has a higher wicking capability with respect to the first liquid than to the second liquid, and is disposed in a siphon fashion with the first or intake end contacting the first liquid and the second or discharge end contacting the second liquid. Because of the different wicking capabilities, a net amount of the first liquid is pumped into the second liquid. The device described above is used as a fuel delivery means for a liquid-feed fuel cell system, which directly utilizes a liquid fuel without an intermediate reforming process, such as a direct methanol fuel cell (DMFC). In this case, a methanol fuel and an aqueous methanol solution are stored separately in two containers and a wick is disposed between the two containers in a siphon fashion, with the container of the aqueous methanol solution communicating with the anode of the DMFC. Methanol is siphoned from the methanol container to the aqueous solution container in-situ when the methanol in the aqueous methanol solution is consumed during the operation of the fuel cell. Through a proper selection of the wick and the containers, the methanol concentration near the anode of the DMFC is maintained within a preferable range.
