基于快速残差插值和卷积神经网络的去马赛克算法

针对传统插值法存在的图像细节不能很好恢复的不足,利用卷积神经网络作为残差插值法的后处理操作,提出了一种基于残差插值和卷积神经网络的去马赛克算法。方法分为初始去马赛克和细节恢复后处理两部分。先用改进的基于梯度的快速残差插值法实现初步去马赛克插值,并针对恢复图像中包含了彩色伪影,细节丢失等问题,再使用深度残差网络学习恢复图像与理想全彩色图像之间的映射,实现后处理。在Kodak数据集和IMAX数据集上的实验结果表明,该方法结果在主观视觉特性和客观评价指标两方面相较于传统方法都有明显改进。     

基于认知图谱的智能问答系统推理模型研究

目前现有问答系统模型大多数都采用模板匹配的方式进行推理,对问题推理不够充分,因此,提出基于认知图谱的问答系统推理模型.依据专业领域知识作为知识源构建本体;并基于该认知图谱构建了"问题-关系"一对一的认知图谱问答系统模型.最后通过将问答问题划分为简单问题与复杂问题分别对问题进行处理,其中简单问题运用BERT+ CRF(Bidirectional Encoder Representations from Transformers+Conditional Random Field)模型进行模板匹配;针对复杂问题运用Node2vec生成子图后用GCN(Graph Convolutional Network)推理模型进行推理,将得出的答案作为输出结果.最后对所提出的模型通过井下作业领域进行了实验,结果表明认知图谱问答模型优于其他算法模型.

Two tobacco DNA-binding proteins with homology to the nuclear factor CREB

The 35S promoter of the cauliflower mosaic virus (CaMV) contains a tandem repeat of the sequence TGACG in the region -83 to -63. This 21-base pair (bp) sequence, called as-1, is involved in root expression of the 35S promoter. When inserted in a promoter of a gene expressed specifically in photosynthetic tissues, as-1 confers high level expression in roots. We have described a factor, ASF-1, that binds specifically to as-1 in vitro. There is a good correlation between ASF-1 binding affinity to as-1 related sequences in vitro and the function of these sequences in vivo. These results strongly suggest that ASF-1 is responsible for the function of as-1. Here we report the isolation of tobacco complementary DNA clones encoding two TGACG-sequence-specific binding-proteins (TGA1a and TGA1b). Sequence analysis of the cDNA clones shows that both proteins contain a basic region that shows high homology to a stretch of basic amino acids in the nuclear factors CREB, GCN4, and c-Jun to a 'leucine-zipper' region. On the basis of binding specificity we propose TGA1a to be a good candidate for ASF-1.

Population structure, differential bias and genomic control in a large-scale, case-control association study

The main problems in drawing causal inferences from epidemiological case-control studies are confounding by unmeasured extraneous factors, selection bias and differential misclassification of exposure. In genetics the first of these, in the form of population structure, has dominated recent debate. Population structure explained part of the significant +11.2% inflation of test statistics we observed in an analysis of 6,322 nonsynonymous SNPs in 816 cases of type 1 diabetes and 877 population-based controls from Great Britain. The remainder of the inflation resulted from differential bias in genotype scoring between case and control DNA samples, which originated from two laboratories, causing false-positive associations. To avoid excluding SNPs and losing valuable information, we extended the genomic control method by applying a variable downweighting to each SNP.     

Genome sequencing and analysis of Aspergillus oryzae

The genome of Aspergillus oryzae, a fungus important for the production of traditional fermented foods and beverages in Japan, has been sequenced. The ability to secrete large amounts of proteins and the development of a transformation system have facilitated the use of A. oryzae in modern biotechnology. Although both A. oryzae and Aspergillus flavus belong to the section Flavi of the subgenus Circumdati of Aspergillus, A. oryzae, unlike A. flavus, does not produce aflatoxin, and its long history of use in the food industry has proved its safety. Here we show that the 37-megabase (Mb) genome of A. oryzae contains 12,074 genes and is expanded by 7-9 Mb in comparison with the genomes of Aspergillus nidulans and Aspergillus fumigatus. Comparison of the three aspergilli species revealed the presence of syntenic blocks and A. oryzae-specific blocks (lacking synteny with A. nidulans and A. fumigatus) in a mosaic manner throughout the genome of A. oryzae. The blocks of A. oryzae-specific sequence are enriched for genes involved in metabolism, particularly those for the synthesis of secondary metabolites. Specific expansion of genes for secretory hydrolytic enzymes, amino acid metabolism and amino acid/sugar uptake transporters supports the idea that A. oryzae is an ideal microorganism for fermentation.
