The water flea Daphnia carinata (D. carinata) reproduces both sexually and parthenogenetically, yet little is known about the genes involved in these processes. To further clarify the reproductive biology of Daphnia and elucidate their unique mechanism of reproductive transformation, we have generated and characterized an expressed sequence tag (EST) data(More)
Many gene expressions in the DNA micro array and gene sequences have missing values in the datasets. It is critical to estimate these missing values accurately, because most of the existing algorithms for gene expression analysis require the complete DNA dataset as an input, which affects the performance of gene classifications. This paper introduces(More)
Every day, thousands of videos are uploaded to the web, creating an ever-growing demand for methods to make them easier to retrieve, search, and index. These videos include both spatial and temporal geographic features captured via camera and embedded sensors, e.g., GPS and the digital compass. The current state-of-the-art video retrieval systems are based(More)
Access control policy is utilized to ensure that the available resources aren't accessed unintentionally. Traditional access control policy approaches generally describe the core elements as a holistic, which has high coupling, thus it leads to a limited flexibility and lower dynamic of the policy. To solve this issue, we proposed a dynamic access control(More)
Restricted to temporal separation during the coupled-waves interaction, aperiodically quasi-phase-matching (QPM) nonlinear crystals are primarily implemented for prechirped pulses, showing limited applications in ultrafast temporal scale. Under the proposed time-synchronization framework, pump and signal waves travel with identical group-velocity, which(More)
Brown algae are photosynthetic multicellular marine organisms. They belong to the phylum of Stramenopiles, which are not closely related to land plants and green algae. Brown algae share common evolutionary features with other photosynthetic and multicellular organisms, including a carbohydrate-rich cell-wall. Brown algal cell walls are composed(More)
— A majority of DNA microarray datasets contain missing or corrupt values and it is critical to estimate these values accurately. These missing values are most often attributed to insufficient experimental resolution or the presence of foreign objects on the experimental slide's surface. To improve existing missing value estimation algorithms, this paper(More)
The 19th century witnessed many advances in scientific enzymology and microbiology that laid the foundations for modern biotechnological industries. In the current study, we analyze the content of original lager beer samples from the 1880s, 1890s and 1900s with emphasis on the carbohydrate content and composition. The historic samples include the oldest(More)
