Previous work reveals that the adult Chinese citrus fly, Bactrocera minax (Enderlein), emerges from the ground in citrus orchards and presumably disperses to alternate food sources in neighboring shrubs and trees, where it stays and becomes reproductively mature, and then later returns to the orchard to lay eggs. We investigated the trajectories of early emerged adult Chinese citrus flies, which were tracked with portable harmonic radar in 2013, 2014, 2015, and 2016 in four different habitats in Hubei province of China that presumably provided food sources for adults. This study we investigated whether early emerged adult Chinese citrus flies migrate into forests. A total of 47 adults were tracked following release in a citrus orchard. Our results showed that a total of 33 adults released in a citrus orchard flew into the forest, and 14 adults that disappeared during the tracking process in the citrus orchard. A total of 10 adults (in 2014) that were tracked and released in the forest flew to the forest. Of the adult flies investigated, 54.5% flew directly into the forest, while the remaining 45.5% finally arrived in the forest after repeatedly adjusting their trajectories. When there were Castanea mollissima Blume (Fagaceae) in the surrounding forest, the proportion of frequency of adult landing on the plant represented 58.3% and 88.5% of landing on all species in 2014 and in 2015, respectively. We conclude that early emerged adult Chinese citrus flies in the mosaic-type citrus orchard of the hilly terrain landform dispersed into adjacent forest.

In the development of commercial promotion, chatbot is known as one of significant skill by application of natural language processing (NLP). Conventional design methods are using bag-of-words model (BOW) alone based on Google database and other online corpus. For one thing, in the bag-of-words model, the vectors are Irrelevant to one another. Even though this method is friendly to discrete features, it is not conducive to the machine to understand continuous statements due to the loss of the connection between words in the encoded word vector. For other thing, existing methods are used to test in state-of-the-art online corpus but it is hard to apply in real applications such as telemarketing data. In this paper, we propose an improved chatbot design way using hybrid bag-of-words model and skip-gram model based on the real telemarketing data. Specifically, we first collect the real data in the telemarketing field and perform data cleaning and data classification on the constructed corpus. Second, the word representation is adopted hybrid bag-of-words model and skip-gram model. The skip-gram model maps synonyms in the vicinity of vector space. The correlation between words is expressed, so the amount of information contained in the word vector is increased, making up for the shortcomings caused by using bag-of-words model alone. Third, we use the term frequency-inverse document frequency (TF-IDF) weighting method to improve the weight of key words, then output the final word expression. At last, the answer is produced using hybrid retrieval model and generate model. The retrieval model can accurately answer questions in the field. The generate model can supplement the question of answering the open domain, in which the answer to the final reply is completed by long-short term memory (LSTM) training and prediction. Experimental results show which the hybrid word vector expression model can improve the accuracy of the response and the whole system can communicate with humans.

Objective: Tan lambs (n = 36, 3 mo old, 19.1±0.53 kg) were used to assess effects of dietary guanidinoacetic acid (GAA) and rumen-protected methionine (RPM) on growth performance, carcass traits, meat quality, and serum parameters. Methods: Lambs were randomly assigned to three treatment groups, with 6 pens per group and 2 lambs per pen. Dietary treatments were: basal diet alone (I); basal diet supplemented with 0.08% GAA+0.06% RPM (II); and basal diet supplemented with 0.08% GAA+0.08% RPM (III). Diets were provided three times a day for 90 d. Intake per pen was recorded daily and individual lamb body weight (BW) was measured monthly. Carcass traits were measured after slaughter and meat quality at the end of the experiment, blood samples were taken on a subgroup of lambs for analysis of indicators mostly related to protein metabolism. Results: Final BW and average daily gain for the first and second month, and for the entire experiment were greater in Treatment II compared to Treatment I (p<0.05), whereas feed to gain ratio was lower (p<0.05). Treatment II had the optimal dressing percentage and net meat weight proportion, as well as crude protein and intramuscular fat concentrations in muscles. Treatment II improved meat quality, as indicated by the greater water holding capacity, pH after 45 min and 48 h, and lower shear force and cooking loss. Dietary supplementation of GAA and RPM also increased the meat color a* and b* values at 24 h. Finally, Treatment II increased total protein, and serum concentrations of albumin and creatinine, but decreased serum urea nitrogen concentrations, indicating improved protein efficiency. Conclusion: In this study, 0.08% GAA+0.06% RPM supplementation improved growth performance and meat quality of Tan lambs.

Purpose: This study aimed to investigate the prevalence, risk factors, and effects of primary nocturnal enuresis (PNE) on physical and mental health in young adults in mainland China. Methods: An anonymous questionnaire was used to collect information including the sociodemographic characteristics, history of PNE, family history, daytime voiding symptoms, Pittsburgh Sleep Quality Index (PSQI) scores, Self-Esteem Scale (SES), and Self-Rating Depression Scale (SDS). A total of 22,500 university students from 23 provinces and 368 cities in mainland China were included. Results: In total, 21,082 questionnaires were collected, and 20,345 of them qualified for statistical analysis. The PNE prevalence was 1.17%, and the distribution of monosymptomatic nocturnal enuresis (MNE) and nonmonosymptomatic nocturnal enuresis (NMNE) was 66.1% and 33.9%, respectively. In total, 28% of respondents with PNE reported bedwetting daily, 31.6% between 1 and 7 times weekly, and 40.4% between 1 and 4 times monthly; 80% of PNE cases had no history of treatment. The prevalence of PNE in patients with a family history, frequency, urgency, urinary incontinence, and recurrent urinary tract infections was significantly higher than in those without these conditions (P<0.001). PNE was significantly correlated with the PSQI total score (sleep quality) (P=0.011). The SES score was lower and the SDS was higher (P<0.001) in the PNE group than in those without PNE. Conclusions: In mainland China, the PNE prevalence among young adults was found to be high, and PNE had significant effects on physical and mental health. Risk factors included a family history, daytime voiding symptoms, and lack of treatment.

Zhang, Bai-Hua,Cheng, Gui-Yu,Xue, Qi,Gao, Shu-Geng,Sun, Ke-Lin,Wang, Yong-Gang,Mu, Ju-Wei,He, Jie Asian Pacific Journal of Cancer Prevention 2013 Asian Pacific journal of cancer prevention Vol.14 No.3

Background: Basaloid squamous cell carcinoma of the esophagus (BSCCE) is a rare and distinctive tumor with no standard treatment. This study aimed to explore treatment in relation to prognosis of the disease. Methods: A total of 142 patients with BSCCE that underwent treatment in our hospital from March 1999 to July 2010 were retrospectively analyzed. All patients received surgery, 42 postoperative radiotherapy and 28 patients chemotherapy. Results: There were 26 patients included in stage I, 60 in stage II, 53 in stage III and 3 in stage IV. The clinical symptoms and macroscopic performances of BSCCE did not differ from those of typical esophageal squamous cell carcinoma. Among 118 patients receiving endoscopic biopsy, only 12 were diagnosed with BSCCE. The median survival time (MST) of the entire group was 32 months, with 1-, 3- and 5-year overall survival (OS) of 81.4%, 46.8% and 31.0%, respectively. The 5-year OS of stage I and II patients was significantly longer than that of stages III/IV, at 60.3%, 36.1% and 10.9%, respectively (p<0.001, p=0.001). The MST and 5-year OS were 59.0 months and 47.4% in patients with tumors located in the lower thoracic esophagus, and 27.0 months and 18.1% in those with lesions in the upper/middle esophagus (p=0.002). However, the survival was not significantly improved in patients undegoing adjunctive therapy. Multivariate analysis showed TNM stage and tumor location to be independent prognostic factors. Furthermore, distant metastasis was the most frequent failure pattern, with a median recurrence time of 10 months. Conclusion: BSCCE is an aggressive disease with rapid progression and a propensity for distant metastasis. It is difficult to make a definitive diagnosis via preoperative biopsy. Multidisciplinary therapy including radical esophagectomy with extended lymphadenectomy should be recommended, while the effectiveness of radiochemotherapy requires further validation for BSCCE.

Shaking Table Study of the Three-Dimensional Isolation of a Cylindrical Reticulated Shell

Gui-bo Nie,Chenxiao Zhang,Zhi-yong Wang,Yu-jie Shi 한국강구조학회 2022 International Journal of Steel Structures Vol.22 No.2

A set of shaking table tests were conducted to investigate the dynamic response characteristics of a single-layer cylindrical reticulated shell (SLCRS) with three-dimensional column-top seismic isolation. The infl uence of infi lled wall on the seismic and isolation performance of the structure was investigated. The dynamic response characteristics of structures with and without seismic isolation were compared to investigate the eff ects of seismic isolation. The dynamic responses of lower-frame models with and without an infi lled wall were also compared to investigate the eff ects of the infi lled wall on the seismic isolation. Results show that the three-dimensional column-top seismic isolation improved the seismic safety of infi lled wall. At the same time, the three-dimensional column-top isolation bearing can signifi cantly reduce the acceleration and stress of the structure. The excellent isolation performance of the three-dimensional isolation bearing promises outstanding application prospects for this isolation bearing in highly seismic areas. In addition, under a small earthquake, the acceleration of the second fl oor with the isolation bearing was unfavorably magnifi ed. Therefore, the seismic performance of the acceleration-sensitive nonstructural components should be improved when the three-dimensional column-top seismic isolation is applied in the areas of low seismicity. The test data and conclusions obtained in the present study can provide theoretical and technical support for the actual engineering application of such three-dimensional seismic isolation bearings.

A NEW CORE – SHELL HYBRID NANOSTRUCTURES OF GOLD NANOROD FOR ENHANCING FLUORESCENCE AND APPLICATION IN DUAL-COLOR IMAGING

LU ZHANG,Peihui Yang,YAN-JIE GUO,JIAN-JUN LUO,GUI-MIN SUN,ZHI-HONG LIANG,YAN-JUAN TANG 성균관대학교(자연과학캠퍼스) 성균나노과학기술원 2014 NANO Vol.9 No.3

A novel core – shell hybrid nanostructure was constructed by employing gold nanorod (AuNR)combined with rhodamine B (RB) as a core and silica as a shell. The poly(sodium 4-styr-enesulfonate) (PSS), a negatively charged polyelectrolyte, played the role of linker to electro-statically trap RB on AuNRs. Due to the °uorescence spectral overlap between RB and AuNRs at560 nm, the red °uorescence and enhanced green °uorescence of the hybrid nanostructures wereobserved obviously, which is capable for dual-color labeling. To reduce toxic side e®ects ofAuNRs, silica was coated on AuNRs as a shell to fabricate the novel core – shell hybrid nano-structure function as a dual-color labeling for cancer-cell imaging. The fabricated compositestructures were characterized by transmission electron microscopy (TEM), absorption spectrum,°uorescence spectrum, zeta potential measurements and laser scanning confocal microscope(LSCM). The experiment results con¯rmed that the obtained hybrid nanostructures providedexcellent photostability, biocompatibility and active surface for further biological functionali-zation. The novel composite structures may have great potential application in cell multicolorlabeling and imaging instead of traditional °uorescent dyes.

Yu-Jie Ren,Fu-Gui Song,Yan-Juan Li,Hong-Qing Zhang 한국멀티미디어학회 2006 한국멀티미디어학회 국제학술대회 Vol.2006 No.-

In the paper, a new mechanization method on the mixed operation of the numerical solutions, analytic solution (if exist), and showing their figures simultaneously for differential equation and their MATLAB programs are presented. With the aid of computer software MATLAB, Euler's method is chosen to illustrate the validity and advantages of the method. As a result, we can not only see the analytic solution, numerical solutions, and their errors but also observe how step size affects the error of the numerical solutions by a figure. The mechanization method can be also applied to other numerical method.
