Ramp-Strike Risk Evaluation Making of Carrier-Based Aircraft
Hai-tao Jiang,Xiao-dong Su,Hui Li 보안공학연구지원센터 2014 International Journal of Control and Automation Vol.7 No.10
To make “Ramp-Strike Risk” evaluation making accurately, this paper introduces a new wave-off risk assessment method based on neural network of carrier-based aircraft. On account of defining “Wave-Off Retain Clearance”, the wave-off operation system with military power and vertical elevator is established as evaluation medium. The “Wave-Off Risk State Area” established by limited wave-off envelope can reduce network training burden, and the quantitative “Ramp-Strike Risk” function with flight state is presented through BP neural network finally. Simulation results show that the risk with flight states can be predicted by using new estimation method, moreover auxiliary rectification and early-warning for landing is provided.

Objective : The clinical and pathological characteristics of 10 cases of cerebral amyloid angiopathy (CAA)-related cerebral lobar hemorrhage (CLH) that was diagnosed at autopsy were investigated to facilitate the diagnosis of this condition. Methods : The clinical characteristics of 10 cases of CAA-related CLH were retrospectively reviewed, and a neuropathological examination was performed on autopsy samples. Results : The 10 cases included two with a single lobar hemorrhage and eight with multifocal lobar hemorrhages. In all of the cases, the hemorrhage bled into the subarachnoid space. Pathological examinations of the 10 cases revealed microaneurysms in two, double barrel-like changes in four, multifocal arteriolar clusters in five, obliterative onion skin-like intimal changes in four, fibrinoid necrosis of the vessels in seven, neurofibrillary tangles in eight, and senile plaques in five cases. Conclusion : CAA-related CLHs were located primarily in the parietal, temporal, and occipital lobes. These hemorrhages normally consisted of multiple repeated CLHs that frequently bled into the subarachnoid space. CAA-associated microvascular lesions may be the pathological factor underlying CLH.

In this study, several chemical treatment techniques commonly used for protein extraction were investigated for recovering glutaryl-7-aminocephalosporanic acid acylase (GLA) from recombinant E. coli cells. The best results were obtained by the combined use of cetyltrimethylammonium bromide (CTAB) and KCl. Subsequently, various extraction conditions, such as cation salt, concentrations of CTAB and KCl, extraction temperature, extraction time, and biomass, were optimized to further enhance the release yield and specific activity of GLA. Our results showed that 110% of GLA was released after treatment with 0.5% CTAB (w/v, %) and 0.3 M KCl at 10°C for 12 h, and its specific activity in this extracting solution was approximately 1.5 times higher as compared to that obtained by sonication. This extraction method could avoid the inactivation of GLA caused by drastic mechanical methods, and also enhance its specific activity for industrial extraction.

The yellow mealworm beetle, Tenebrio molitor (Coleoptera: Tenebrionidae), is a common insect pest that damages stored grain. The insect olfactory co-receptor (Orco) is a transmembrane protein localized on the surface of the dendrites of olfactory sensory neurons and plays an essential role in the olfactory perception. In this study, an Orco ortholog (named as Tmol\Orco) inT.molitorwas characterized. The deduced amino acid sequence of Tmol\Orco shared significant high identities with Orcos in other insect species from distinct Orders. Reverse transcription quantitative PCR (RT-qPCR) analysis showed that Tmol\Orco was predominantly expressed in the antennae of both male and female adults, and the difference between male antennae and female antennae was not significant. Double-stranded RNA (dsRNA) directly against the Tmol\Orco mRNA was synthesized and injected into the T. molitor male adults, RT-qPCR results demonstrated that the transcription level of Tmol\Orco was significantly reduced at 6 d after the injection. The mate-seeking behavior of Tmol\Orco-silenced beetles was significantly inhibited. Compare to the control individuals, the percentage of Tmol\Orco-silenced beetles successfully find mateswas significantly decreased and the average time they spent for searching were significantly increased. These results provided first direct evidence that suppression of Tmol\Orco transcription contributes to the decline in mate recognition of T. molitor
Dynamic response analysis for structures with interval parameters
Chen, Su Huan,Lian, Hua Dong,Yang, Xiao Wei Techno-Press 2002 Structural Engineering and Mechanics, An Int'l Jou Vol.13 No.3
In this paper, a new method to solve the dynamic response problem for structures with interval parameters is presented. It is difficult to obtain all possible solutions with sharp bounds even an optimum scheme is adopted when there are many interval structural parameters. With the interval algorithm, the expressions of the interval stiffness matrix, damping matrix and mass matrices are developed. Based on the matrix perturbation theory and interval extension of function, the upper and lower bounds of dynamic response are obtained, while the sharp bounds are guaranteed by the interval operations. A numerical example, dynamic response analysis of a box cantilever beam, is given to illustrate the validity of the present method.

Aims: This study was conducted to evaluate the levels of TNF-${\alpha}$, IL-6, IL-8 and VEGF in serum of patients with non- small cell lung cancer, for assessing their possible diagnostic and prognostic roles. Methods: We enrolled 48 patients newly diagnosed with non-small cell lung cancer and 40 healthy controls. TNF- ${\alpha}$, IL-6 and IL-8 levels were measured in the serum of all the subjects with specific radioimmunoassay kits, while EGF was analyzed by sandwich enzyme immunoassay techniques. Results: A statistically significant difference was observed between lung cancer patients and the control group regarding the values of TNF-${\alpha}$, IL-6, IL-8 and VEGF in serum. Moreover, TNF-${\alpha}$, IL-8 and VEGF levels were higher in patients with advanced stages compared to early stages. In addition, higher serum levels of TNF-${\alpha}$, IL-6, IL-8 and VEGF were found in smokers than in non-smokers, both in patients and controls. Conclusion: Serum levels of TNF-${\alpha}$, IL-6, IL-8 and VEGF were all elevated in lung cancer patients, suggesting that inflammatory cytokines could be jointly used as a screening tool. Though TNF-${\alpha}$, IL-8 and VEGF levels were related to advanced disease, long-term survival studies of NSCLC patients should be performed to confirm whether they can act as biomarkers of advanced disease. In addition, smoking would be an important contributor to the processes of inflammation and lung cancer.

Expression of Glypican-3 is Highly Associated with Pediatric Hepatoblastoma: a Systemic Analysis
Xiong, Xiao-Li,Qin, Huan,Yan, Su-Qi,Zhou, Li-Shan,Chen, Peng,Zhao, Dong-Chi Asian Pacific Journal of Cancer Prevention 2015 Asian Pacific journal of cancer prevention Vol.16 No.3
Objective: Glypican-3 (GPC3) is reported to be an oncofetal protein that is a useful diagnostic immunomarker for hepatoblastoma. However, the results are not inclusive. This study systemically investigated the association between expression of GPC3 and pediatric hepatoblastoma. Methods: Clinical studies evaluating the association were identified using a predefined search strategy. GPC3 immunohistochemistry was applied in the pathological diagnosis of hepatoblastoma using the monoclonal antibodies with formalin-fixed and paraffin-embedded specimens. Positive predictive rates for the association between expression of GPC3 and pediatric hepatoblastoma were calculated. Results: Specimens from four clinical studies which including 134 patients with pediatric hepatoblastoma tested by GPC3 immunohistochemistry were considered eligible for inclusion. Systemic analysis showed that, in all patients, pooled positive predictive rate of the association between expression of GPC3 and pediatric hepatoblastoma was 95.5% (128/134). Conclusion: This systemic analysis suggests that the expression of glypican-3 is highly associated with the diagnosis of pediatric hepatoblastoma.
