Dynamic response of curvilinearly stiffened plates under thermal environment
Jingze Liu,Qingguo Fei,Shaoqing Wu,Dahai Zhang,Dong Jiang 대한기계학회 2021 JOURNAL OF MECHANICAL SCIENCE AND TECHNOLOGY Vol.35 No.6
An improved finite element modeling method is developed for isotropic curvilinearly stiffened plates under a thermal environment. The existing modeling method for curvilinearly stiffened plates avoids the difficulty of node overlap, which is suitable for plates with different thicknesses. By introducing the influence of temperature on material parameters and thermal stress on additional stiffness, the existing method is improved and extended to the study of thermodynamics. The proposed method is verified by modal test at normal temperature and commercial finite element software at the thermal environment. The variation of dynamic characteristics with temperature under different boundary conditions was studied. Results show that when the boundary conditions are asymmetric, the influence of temperature on the thermal mode shape is more significant than the case of symmetrical.
Nanocellulose-Based Hybrid Hydrogels as Flexible Cathodes of Aqueous Zn-Ion Batteries
Jingze Liu,Jiamei Lai,Xingyuan Huang,Hesheng Liu 성균관대학교(자연과학캠퍼스) 성균나노과학기술원 2019 NANO Vol.14 No.4
Cellulose nanofibers, detached from natural plants, are very promising for applications in the energy storage devices. The swelling of cellulose nanofibers provides abundant paths in the hybrid hydrogels for ion diffusion towards the active material. There is an optimal composition of 50 wt.% for cellulose nanofibers in the hybrid hydrogels due to the balance between ion diffusion and electron transport, that is, facilitated by conductive graphite nanoplatelets. The aqueous Zn-ion batteries, assembled from the optimized hybrid hydrogels, have a high-specific capacity of 149.4 mAh/g and energy density of 113.2mWh/g, respectively. Moreover, high flexibility of the aqueous Zn-ion batteries is guaranteed by the hybrid hydrogels. There is only a little decay in the electrochemical performance under mechanical bending.
Circ_0026359 induces HOXA9 to regulate gastric cancer malignant progression through miR‑140‑3p

Recent researches indicate the key role of circRNA in gastric cancer (GC) progression. However, the role of circ_0026359 in GC progression remains unclear. This study aims to analyze the role of circ_0026359 in GC development and the underlying mechanism. The results showed that compared with controls, GC tissues and cells displayed high circ_0026359 and HOXA9 expression, and low miR-140-3p expression. Depletion of circ_0026359 repressed cell proliferation, migration, invasion and glycolysis, and induced cell apoptosis. Circ_0026359 knockdown inhibited neoplasm growth in vivo. Under-expression of miR-140-3p, a target miRNA of circ_0026359, relieved the effects of circ_0026359 knockdown on GC progression. Additionally, HOXA9 was regulated by the circ_0026359/miR-140-3p axis. Thus, circ_0026359 absence inhibited GC progression by miR-140-3p/HOXA9 pathway, which provided an effective therapeutic target for GC.

The identification of areas of endemism (AOEs) has been a major challenge in biogeography. In the present study, parsimony analysis of endemicity (PAE) was used to define the AOEs of scale insect species in China. A total of 11 Chinese scale insect endemic areas, Tianshan mountain (A2-B1), South Tibet (H2-H3), Eastern Qinling Mountain (E12-E13), Dalou mountain (G11-H11), West Yunnan (I9, J9-J10, K9), Hainan Island-South west Guangdong (M13-L14), South Guangdong (K15-K16), South Fujian (J17-J18), Center Zhejiang (H18-H19), Taiwan Island (K19-L19) and association of Henan and Hubei (F15-G16), had been identified based on a distribution database of 506 endemic scale insect species. The Chinese areas of scale insects endemism showed a remarkable mountain effect. Hainan and Taiwan islands showed considerable endemism. Moreover, most of these AOEs were found to be endemic sites for several other plants and animals. These results will provide important information for further studies on scale insects diversity in China.

Gynandromorphic ticks are extremely rare, and often attract parasitologists’ attention. During our examination of tick specimens, an engorged gynandromorph of Hyalomma asiaticum was noticed. This is the first record of gynandromorphic ticks from China. In this study, several important morphological structures of normal and gynandromorphic H. asiaticum were analyzed. Comparing to the normal H. asiaticum, the gynandromorphic specimen was a typical bipartite protogynander. Its right side showed normal female characteristics, whereas the left side had normal male traits. Different from other gynandromorphic ticks containing 1 anus, this tick reported here had 2 complete anuses, and the anus of the male part had a single adanal plate.

A continuous conversion process of rice starch hydrolysate to 2-keto-D-gluconic acid (2KGA) by Arthrobacter globiformis C224 was developed. Its feasibility for industrial application was also evaluated. Results showed that the initial cell concentration exceeding 1.25 g/L met the continuous 2KGA production at a stable dilution rate and media composition, while the dilution rate and feeding glucose concentration had a significant effect on 2KGA production performance. The optimal operating parameters were obtained as: 0.090/h of dilution rate and 171.0 g/L of feeding glucose concentration. Under these conditions, the steady state had a produced 2KGA concentration of 124.74 g/L, average volumetric productivity of 11.23 g/L/h,and yield of 0.97 g/g. In conclusion, continuous 2KGA production by the A. globiformis C224 strain would be a superior industrial process for the production of 2KGA in terms of its high 2KGA productivity and yield.

In order to explore tick proteins as potential targets for further developing vaccine against ticks, the total proteins of unfed female Dermacentor silvarum were screened with anti-D. silvarum serum produced from rabbits. The results of western blot showed that 3 antigenic proteins of about 100, 68, and 52 kDa were detected by polyclonal antibodies, which means that they probably have immunogenicity. Then, unfed female tick proteins were separated by 12% SDS-PAGE, and target proteins (100, 68, and 52 kDa) were cut and analyzed by LC-MS/MS, respectively. The comparative results of peptide sequences showed that they might be vitellogenin (Vg), heat shock protein 60 (Hsp60), and fructose-1, 6-bisphosphate aldolase (FBA), respectively. These data will lay the foundation for the further validation of antigenic proteins to prevent infestation and diseases transmitted by D. silvarum.
