Odorant‐degrading enzymes (ODEs) have been found in insect antennae and play a critical role in signal chemical degradation once the message is conveyed. Significant progress has been made in characterizing ODEs in a variety of pests but very little is known in their natural enemies. We have carried out an antennae‐ and sex‐specific transcriptome of Aphidius gifuensis, a natural enemy of aphid, to identify the candidate ODEs. Based on the antennae‐ and sex‐specific transcriptome, a total of 100 putative ODEs were identified including one aldehyde oxidase (AOX), four alcohol dehydrogenases (ADs), eight UDP‐glucuronosyltransferases (UGTs), 45 cytochrome P450 (P450s), nine glutathione S‐transferases (GSTs) and 40 carboxylesterases (CCEs or CXEs). Additionally, we used RT‐qPCR to determine the expression profiles of these genes in tissues of both sexes. Based on the phylogenic analysis and tissue‐expression patterns, AgifEstE4, AgifCXE3, AgifCCE4, AgifCCE7, and AgifCCE18 were suggested as key ODEs in A. gifuensis. In addition, the female or male specifically enriched genes, such as AgifCCE17, AgifEstB1, AgifCYP18a1, AgifUGT2C2, were also considered to involve in the chemosensory processing in A. gifuensis. This study not only identified the candidate ODEs in A. gifuensis but also provided source for further exploration of the molecular mechanisms of chemical signal transductions in A. gifuensis, as well as other hymenopteran species.

Background: To determine the amount of co-expression of IDO and EGFR in breast cancer patients. Materials and Methods:In order to obtain the distribution of co-expression of IDO and EGFR in breast cancer, we tested 110 breast cancer paraffin tissue blocks with immunohistochemical methods. Then we investigated the relationship between the diagnostic and pathologic characteristics (tumor size, lymph node status, histologic grade, the gene expression of ER, PR, HER2, p53, Ki67 and PCNA) with the situation of co-expression of IDO and EGFR by reviewing the medical records of 32 breast cancer patients. Results: Among 110 breast cancers, 32 cases demonstrated IDO and EGFR co-expression (29.1%), IDO and EGFR synchronous co-expression being found in 19.1% and asynchronous in 10.0%. Conclusions: IDO and EGFR were co-expressed in breast cancer, including synchronous and asynchronous co-expression. The results suggest that considering IDO and EGFR as two indicators for breast cancer treatment or prognosis analysis provides a potential option of individual treatment for the portion of breast cancer patients with co-expression of IDO and EGFR.

The interpretation of Hua Yue Hen has long been confined to the text itself, while the research about the author, the real life of related figures, and the social context is insufficient. Based upon the historical materials about Wei Xiuren’s life experiences and the social context in which the book was written, this paper aims to probe the gist of the novel and the author’s motive from a humanist perspective. Furthermore, a defense of the novel is included from some of its criticisms.

We adopt the PASTEL catalog combined with SIMBAD radial velocities as a testing standard to validate the stellar parameters (effective temperature $T_{eff}$, surface gravity log g, metallicity [Fe/H] and radial velocity $V_r$) from the first data release (DR1) of The Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) survey. After applying data reduction and temperature constraints to the sample obtained by cross-identification, we compare the stellar parameters from DR1 and PASTEL. The results show that the DR1 results are reliable under certain conditions. We derive a dispersion of 110 K, 0.19 dex, 0.11 dex and $4.91kms^{-1}$ in specified effective temperature ranges, for $T_{eff}$, log g, [Fe/H] and $V_r$ respectively. Systematic errors are negligible except for those of $V_r$. In addition, for stars with PASTEL [Fe/H] < -1:5, the metallicities in DR1 are systematically higher than those in PASTEL.

Objective: Hypoactivity in the reward system among patients with attention deficit hyperactivity disorder (ADHD) is a well-known phenomenon. Whether the activity in the reward pathway is related to harm avoidance, such as in sensitivity to punishment, is unclear. Evidence regarding the potential difference between ADHD patients and controls in terms of this association is scarce. Methods: Event-related functional magnetic resonance imaging was conducted on subjects performing the Iowa gambling test. Fourteen adults with ADHD and 14 controls were enrolled in the study. Results: Harm avoidance was found to be positively correlated with the activities of the bilateral orbitofrontal cortex and right insula in individuals with ADHD. A group difference was also confirmed. Conclusion: Understanding the roles of harm avoidance and brain activation during risk tasks is important.

In this experiment, we selected "Tangshan bone china" 10.5-inch white porcelain flat plate produced by five differententerprises as experimental samples to study the erosion of bone porcelain enamel by different kinds of acidic reagents atdifferent temperatures. The specific experimental process was as follows: at different temperatures, 20% hydrochloric acid,30% sulfuric acid, 100 g/L citric acid and 10% acetic acid were used to continuously erode the sample glaze for 10h, and thewhiteness and 45º mirror direction gloss were measured every 2h. The results show that different acidic reagents at differenttemperatures have significant differences in the erosion characteristics and strength of bone porcelain glaze, and the corrosionresistance of products from different enterprises also have significant differences.
Collaboratively Modeling Buildings from Large-scale street-side and Aerial Images

In this paper we present a new collaborative modeling approach which is able to produce 3D building models from street-side images and aerial images by computer vision techniques. The approach adopts the idea of pipelining manufacture. It divides the modeling process into several steps, which consists of a pipeline. Some steps can be done automatically, the others require human intervention. Furthermore, the computing resources are allocated to these steps according to their requirements. That is, some steps are performed on single workstation, while the others are done by a cluster of workstations. Base on this idea, we develop a prototype distributed system for modeling large-scale urban scene by team. In this system, the modeling workload is balanced along the pipeline, and the waiting time between steps is greatly reduced. Moreover, the human intervention that the system needs is simple and the system’s learning curve is short for ordinary users.

In order to determine the susceptibility of Ipomoea cairica to herbivory, the compensatory growth and photosynthetic characteristics of I. cairica plants were measured after simulated herbivory by leaf trimming in three patterns: leaf-apex removal, leaf-edge removal, and perforation. The leaf-edge removal resulted in a significantly reduced total biomass and root biomass of the plants, but the leaf-apex removal and perforation had no significant influence on the plant growth. The defoliation patterns had significant effects on the photosynthesis of I. cairica. The net photosynthetic rate and stomatal conductance of the plants whose leaf edges had been removed were the highest among the three defoliation patterns and the fraction of absorbed light that is used in Photosystem II photochemistry increased greatly, while the fraction of light energy that is dissipated thermally decreased. The increased photosynthetic rate as a result of the leaf-edge removal treatment could be attributed to a decrease in stomatal limitation and an increase in the Rubisco content, as well as higher photosynthetic efficiency and less light energy being dissipated as heat. Increased photosynthesis in the plants whose leaf edges had been removed changed the carbon allocation and resulted in less root development. As the expansion of I. cairica primarily depends on clonal growth, smaller roots could limit its uptake of nutrients from the soil. These direct and indirect effects indicate that leaf-edgefeeding herbivores could have potential in the biological control of I. cairica.

A well-defined three-dimensional (3-D) reconstruction of bone-cartilage transitional structures is crucial for the osteochondral restoration. This paper presents an accurate, computationally efficient and semi-automated algorithm for the alignment and segmentation of two-dimensional (2-D) serial to construct the 3-D model of bonecartilage transitional structures. Entire system includes the following five components: (1) image harvest, (2) image registration, (3) image segmentation, (4) 3-D reconstruction and visualization, and (5) evaluation. A computer program was developed in the environment of Matlab for the semi-automatic alignment and automatic segmentation of serial sections. Semi-automatic alignment algorithm based on the position’s cross-correlation of the anatomical characteristic feature points of two sequential sections. A method combining an automatic segmentation and an image threshold processing was applied to capture the regions and structures of interest. SEM micrograph and 3-D model reconstructed directly in digital microscope were used to evaluate the reliability and accuracy of this strategy. The morphology of 3-D model constructed by serial sections is consistent with the results of SEM micrograph and 3-D model of digital microscope.
