For the problem that the use effect of food processing information system is poor due to absence of knowledge acquisition measures and knowledge self-updating function, a knowledge acquisition approach based on rough set is put forward. First, the approach establishes a set of predicted samples for the relationship between food processing parameters and product quality; then uses the discretization of continuous attribute, attribute reduction and rule extraction algorithm of rough set to acquire automatically predicted knowledge from a large number of predicted sample sets, and then saves the predicted knowledge in the knowledge base of expert system; finally, realizes the extraction of knowledge of food processing process based on the inference engine, which greatly enhances the effectiveness and practicality of the acquired knowledge in online aided decision system of the food processing quality and safety.

Background: The accessory tendon of the extensor hallucis longus (ATEHL) muscle is a common abnormal structure, and its clinical significance remains debatable. In this study, we provide the incidence of the ATEHL and characterize its morphological types in Asian cadavers and investigate its clinical applications. Methods: The tendons from 50 adult cadaveric feet, fixed in 10% formalin, were analyzed. We measured the length and width of both the ATEHL and the extensor hallucis brevis (EHB). Results: All dissected specimens had an ATEHL. The first metatarsophalangeal joint was surrounded by an accessory tendon that inserted onto the joint capsule and the dorsal base of the proximal phalanx. We classified the ATEHL into 3 types based on their directions. Differences in ATEHL type based on sex were not statistically significant. Conclusions: We found an ATEHL in all cadaveric specimens in this study. We surmise that the ATEHL acts as an antagonist with the EHB when the toe is extending, which might help prevent the occurrence of hallux valgus deformity.

Gamete development is a complex process during the plant reproductive life cycle. A global vision of the molecular mechanisms regulating gametic development would enhance our understanding of developmental similarities and differences between male and female reproductive pathways in plants. In this study, we applied comparative transcriptomics to characterize gene expression during sporogenesis and gametogenesis in Arabidopsis. Compared with genes expressed in leaves, 11,112 and 10,133 differentially expressed genes (DEGs) were identified in the anthers and ovules, respectively. The shared DEGs exhibited a similar expression pattern regarding cell cycle and chromatin dynamics, but DEGs associated with cell wall formation and pectin modifications were prevalent during male development, reflecting dynamic changes during pollen wall development in anthers. In contrast, DEGs related to DNA repair, homologous recombination, and RNA-directed DNA methylation (RdDM) were comparatively over-represented in ovules, probably indicating a relatively intensified mechanism for supervising genome fidelity during female gametogenesis. In addition, DEGs related to brassinolide (BR) synthesis and signaling pathway were also highly enriched in ovules, suggesting a pivotal role in female gamete development. Collectively, our results provide a contrasting transcriptional atlas in developing anthers and ovules, and shed new light on our global understanding of gamete development in plants.

In order to overcome the blindness of chaotic search, improve the convergence speed and global solving ability of the basic ant colony optimization(ACO) algorithm, an improved ACO algorithm based on combining multi-population strategy, adaptive adjustment pheromone strategy, chaotic search method and min-max ant strategy (MPCSMACO)is proposed in this paper. In the proposed MPCSMACO algorithm, the multi-population strategy is introduced to realize the information exchange and cooperation among the various types of ant colony. The chaotic search method with the ergodicity, randomness and regularity by using the logistic mapping is used to overcome too long search time, avoid falling into the local extremum in the initial stage and improve the search accuracy in the late search. The min-max ant strategy is used to avoid the local optimization solution and the stagnation. And the ants with different probability search different area according to the concentration of pheromone, so as to reduce the search number of the blindness of chaotic search method. Several Benchmark functions are selected to testify the performance of the MPCSMACO algorithm. The experiment results show that the MPCSMACO algorithm takes on the better global search ability and convergence performance.

In this paper, the effects of O2 and N2 sintering atmospheres on the physical phase and microstructure of BSIT ceramics wereinvestigated by using In3+-doped BST ceramics as the research object. And then the dielectric properties of the ceramics inthe frequency range of 20Hz-300000 Hz were investigated by constructing ceramic capacitors. The results show that theceramic sintered in N2 atmosphere has a denser morphology and a higher dielectric constant of 862 compared with the ceramicsintered in O2 atmosphere, and the dielectric loss is reduced by about 39% in the high frequency stage.

Bladder cancer is one of the most common types of cancer. Most gene mutations related to bladder cancer are dominantly acquired gene mutations and are not inherited. Previous comparative transcriptome analysis of urinary bladder cancer and control samples has revealed a set of genes that may play a role in tumor progression. Here we set out to investigate further the expression of two candidate genes, centromere protein U (CENPU) and mitochondrial ribosomal protein s28 (MRPS28) to better understand their role in bladder cancer pathogenesis. Our results confirmed that CENPU is up-regulated in human bladder cancer tissues at mRNA and protein levels. Gain-of-function and loss-of-function studies in T24 human urinary bladder cancer cell line revealed a hierarchical relationship between CENPU and MRPS28 in the regulation of cell viability, migration and invasion activity. CENPU expression was also up-regulated in in vivo nude mice xenograft model of bladder cancer and mice overexpressing CENPU had significantly higher tumor volume. In summary, our findings identify CENPU and MRPS28 in the molecular pathogenesis of bladder cancer and suggest that CENPU enhances the progression of bladder cancer by promoting MRPS28 expression.
