        Enhancement of attraction to sex pheromone of Grapholita molesta (Busck) (Lepidoptera: Tortricidae) by structurally unrelated sex pheromone compounds of Conogethes punctiferalis (Guenée) (Lepidoptera: Crambidae)

        Deng Jianyu,Shen Zhijie,Wang Fumin,Liu Tao,Hong Wenying,Fang Minghua,Wo Linfeng,Chu Sijie 한국응용곤충학회 2022 Journal of Asia-Pacific Entomology Vol.25 No.1

        Grapholita molesta (Busck) (the oriental fruit moth; OFM) and Conogethes punctiferalis (Guenée) are both fruit and stem borers with overlapping habitats, occurrences, and outbreak cycles. These two species are in different families and they have completely different sex pheromone components. Here, the effects of the sex pheromone components of C. punctiferalis, (E)-10-hexadecenal (E10-16:Ald) and (Z)-10-hexadecenal (Z10-16:Ald) and their mixture, were evaluated on the sexual communication of OFM by examining electrophysiological (EAG) and behavioral responses. We found that a considerably large amount of E10-16:Ald or Z10-16:Ald and a tiny amount of OFM pheromone elicited comparable EAG responses in OFM males, indicating the low antennal olfactory sensitivity of OFM males to the heterospecific pheromone compounds. In two different peach orchard parcels, captures of OFM by their pheromone lures baited in delta traps were increased by at least 1.5 times when OFM pheromone lures were combined with lures that contained 1000 μg of either E10-16:Ald, Z10-16:Ald or their mixture. In two other pear orchard parcels, both E10-16:Ald and Z10-16:Ald increased captures of OFM in Unitraps in a dose-dependent manner with more than a four-fold increase. Therefore, the enhanced attractiveness of OFM lures by the two interspecific pheromones suggests their potential application to improve mass trapping, population monitoring and mating disruption of OFM.

        A Model Predictive Current Control Based on Adaline Neural Network for PMSM

        Li Hongfeng,Liu Zhengyu,Shao Jianyu 대한전기학회 2023 Journal of Electrical Engineering & Technology Vol.18 No.2

        The parameter mismatch seriously affects the control performance of the model predictive current control (MPCC). Aiming at improving the parameter robustness of MPCC, a MPCC method based on Adaline neural network for permanent magnet synchronous motor (PMSM) is established. First, the parameters sensitivity analysis of PMSM incremental current prediction model is carried out that eliminates effects of rotor flux linkage mismatch and resistance mismatch. Therefore, a new incremental current prediction model is built, which does not require rotor flux and resistance parameters. Second, based on the above model, Adaline neural network strategy is introduced to identify the inductance parameters which has a variable momentum to improve accuracy. Then, the strategy proposed in this paper has strong robustness to parameter mismatch. Finally, experiment results verify that the proposed method can effectively improve the parameter robustness.

        Relationship between Porosity and the Modified Constitutive Model Parameters of Asphalt Concrete Core Material

        Zhoumei Chang,Donghai Liu,Jianyu Liang 대한토목학회 2023 KSCE Journal of Civil Engineering Vol.27 No.10

        Porosity is a key control index for ensuring the compaction quality of rockfill dams with asphalt concrete cores. The porosity of the asphalt mixture is an important factor for an asphalt concrete core dam to obtain adequate strength and control the core deformation. However, the compaction quality (i.e., porosity) of the asphalt core wall inevitably exhibits spatial differences during actual construction process. To analyze the quantitative relationship between the porosity of the asphalt concrete core and the Duncan-Chang model parameters, triaxial tests under different confining pressures were carried out with asphalt concrete samples of different porosities. Based on the test results, the applicability of the Duncan-Chang model was assessed. Aiming at the limitation of the Duncan-Chang model, which is unable to characterize the strain softening and shear dilatancy of materials, a modified constitutive model of the asphalt concrete core was proposed. The determination method of the proposedmodel parameters was provided and verified by triaxial test results. A regression relationship was established between the porosity of the core material and the parameters of the modified constitutive model. This study provides a prerequisite for conducting refined finite element analysis on the mechanical performance of the asphalt core rockfill dams, taking into account the spatial differences in compaction quality of the asphalt concrete core.

        Adaptive Weight Collaborative Complementary Learning for Robust Visual Tracking

        ( Benxuan Wang ),( Jun Kong ),( Min Jiang ),( Jianyu Shen ),( Tianshan Liu ),( Xiaofeng Gu ) 한국인터넷정보학회 2019 KSII Transactions on Internet and Information Syst Vol.13 No.1

        Discriminative correlation filter (DCF) based tracking algorithms have recently shown impressive performance on benchmark datasets. However, amount of recent researches are vulnerable to heavy occlusions, irregular deformations and so on. In this paper, we intend to solve these problems and handle the contradiction between accuracy and real-time in the framework of tracking-by-detection. Firstly, we propose an innovative strategy to combine the template and color-based models instead of a simple linear superposition and rely on the strengths of both to promote the accuracy. Secondly, to enhance the discriminative power of the learned template model, the spatial regularization is introduced in the learning stage to penalize the objective boundary information corresponding to features in the background. Thirdly, we utilize a discriminative multi-scale estimate method to solve the problem of scale variations. Finally, we research strategies to limit the computational complexity of our tracker. Abundant experiments demonstrate that our tracker performs superiorly against several advanced algorithms on both the OTB2013 and OTB2015 datasets while maintaining the high frame rates.

        Design and Characteristic Measurement of 8000 mm Large Aperture Integrating Sphere

        Zhao Zhang,Zhi Wan,Xiansheng Li,Hongxing Liu,Jingxu Sun,Zexun Liu,Yamin Wang,Jianwei Ren,Jianyue Ren 한국광학회 2016 Current Optics and Photonics Vol.20 No.4

        Integrating spheres play a central role in the radiometric calibration of remote sensors. With thedevelopment of the wide field of view (FOV) remote sensors, aperture diameters of remote sensors arebecoming larger and larger. To satisfy the radiometric calibration requirements of full FOV and fullaperture, an 8000mm diameter large aperture integrating sphere uniform source with a variable exit portwas designed and manufactured. This integrating sphere will be used for pre-launch test and radiometriccalibration of remote satellites. In this paper, optical theories were used to design the output spectralradiance. The LightTools software based on ray-tracing simulation method was used to determine the bestcombination and distribution of inner light sources. A spectral experiment was made to verify the spectralradiance design. To reduce the influence of longtime power-on, a new characteristic measurement methodwas developed to obtain the radiation characteristic of the integrating sphere, which could greatly improvethe measuring efficiency. This method could also be applied to measure other large aperture uniformsources. The obtained results indicate that the spatial uniformity is 98.35%, and the angular uniformityat center position is 98.78%.

        Identification and differential expression of two isogenes encoding 1-deoxy-D-xylulose 5-phosphate reductoisomerase in Glycine max

        Man Zhang,Deyue Yu,Kai Li,Jianyu Liu 한국식물생명공학회 2012 Plant biotechnology reports Vol.6 No.4

        Plant 1-deoxy-D-xylulose 5-phosphate reductoisomerase (DXR) were considered to be encoded by single copy. In this study, we successfully isolated two DXR isogenes, designated GmDXR1 and GmDXR2, from soybean. The multicopy nature of DXRs in soybean was supported by Southern blot. Alignment of the two GmDXRs showed the presence of the N-terminal transit peptide for plastids, the conserved cleavage site, prolinerich region, and the NADPH-binding motif. Phylogenetic analysis revealed GmDXR1 and GmDXR2 belonged to different branches of angiosperm DXRs clusters. Expression pattern analysis indicated that GmDXR1 was expressed in all analyzed organs except the pod walls, with the highest level in seeds, whereas no message was detected for GmDXR2. In response to heat stress, GmDXR1 showed declined transcript levels in the experiments; in contrast,GmDXR2 was highly responsive, with mRNA accumulation peaking at 6 h after treatment. We also demonstrated that both GmDXRs were localized in chloroplasts. Overexpression of GmDXRs induced increased contents of various isoprenoids (chlorophyll, carotenoids, and gibberellins),but with reduced level of ABA, indicating that GmDXRs participate in the control of differential isoprenoid biosynthesis of the MEP pathway. This work provides a new insight into the wide presence of multicopies of DXR enzyme in plants.
