Plasmonic Nanoantennae Fabricated by Focused Ion Beam Milling
Jiang-Tao Lv,Yuan Yan,Wei-Kang Zhang,Yun-Hui Liu,Zi-Yu Jiang,Guang-Yuan Si 한국정밀공학회 2015 International Journal of Precision Engineering and Vol. No.
We show a novel approach to fabricate plasmonic nanoantennae based on a maskless focused ion beam nanoring patterning process. Antenna nanoarrays with desired outlines are achieved by precisely controlling the geometric parameters during the milling process. Various nanoantenna designs of bow-tie, nanoclusters (pentamers), and ellipsoid shaped satellites surrounded particle lattices arerealized. The whole fabrication method is programmable and monolithic since only a one-step milling process is involved. The opticalproperties are experimentally characterized. Such nanoantennae may find extensive applications in chemical/bio-sensing due toremarkably enhanced near field intensity at the plasmon resonance.
Experimental behavior of circular flyash-concrete-filled steel tubular stub columns
Si-Ping Li,Yang Zhang,Guang-Yuan Fu,Chen-Jiang Yu,Bing Chen,She-Xu Zhao 국제구조공학회 2016 Steel and Composite Structures, An International J Vol.22 No.4
The paper presents an experimental study of the structural behavior of circular flyash-concrete-filled steel tubular stub columns under axial compressive loads. In this study, 90% and 100% by weight of the cement in the concrete core was replaced with flyash. Twenty-seven specimens were tested to study the influence of flyash content, wall thickness of the steel tube, and curing age on the ultimate capacity and confinement effect. The experimental results were compared with the design values calculated using AISC-LRFD (1999), ACI (1999), AIJ (1997) and Eurocode 4 (1994). From the experimental study, it was determined that the confinement effect of circular steel tubes filled with high content flyash concrete was better than that of specimens filled with ordinary Portland cement concrete. The 5.88-mm-thick steel tube filled with 100% flyash concrete was equivalent in strength to a steel tube filled with C30 concrete at 28 days.

Radioprotective effects of amentoflavone were investigated by examining cell viability, apoptosis, cell cycling concentrations of intracellular ROS (reactive oxygen species), and relative mitochondrial mass by flow cytometry after $^{60}Co$ irradiation. Pretreatment with amentoflavone 24 hours prior to 8 Gy $^{60}Co$ ${\gamma}$-ray irradiation significantly inhibited apoptosis, promoted the G2 phase, decreased the concentration of ROS and mitochondrial mass. These results collectively indicate that amentoflavone is an effective radioprotective agent.
Study on rectangular concrete-filled steel tubes with unequal wall thickness
Yang Zhang,Chen-Jiang Yu,Guang-Yuan Fu,Bing Chen,She-Xu Zhao,Si-Ping Li 국제구조공학회 2016 Steel and Composite Structures, An International J Vol.22 No.5
Rectangular concrete-filled steel tubular columns with unequal wall thickness were investigated in the paper. The physical centroid, the centroidal principal axes of inertia, and the section core were given. The generalized bending formula and the generalized eccentric compression formula were deduced, and the equation of the neutral axis was also provided. The two rectangular concrete-filled steel tubular stub specimens subjected to the compression load on the physical centroid and the geometric centroid respectively were tested to verify the theoretical formulas.

Tissue-specific gene expression is regulated by epigenetic modification involving trans-acting factors. Here, we identified that the human MAGEB16 gene and its mouse homolog, Mageb16, are only expressed in the testis. To investigate the mechanism governing their expression, the promoter methy-lation status of these genes was examined in different samples. Two CpG islands (CGIs) in the 5` upstream region of MAGEB16 were highly demethylated in human testes, whereas they were methylated in cells without MAGEB16 expression. Similarly, the CGI in Mageb16 was hypomethylated in mouse testes but hypermethylated in other tissues and cells without Mageb16 expression. Additionally, the expression of these genes could be activated by treatment with the demethylation agent 5`-aza-2`- deoxycytidine (5`-aza-CdR). Luciferase assays revealed that both gene promoter activities were inhibited by methylation of the CGI regions. Therefore, we propose that the testis-specific expression of MAGEB16 and Mageb16 is regulated by the methylation status of their promoter regions. [BMB Reports 2014; 47(2): 86-91]

Background/Aims A large number of studies have shown that function constipation (FC) has an extremely high incidence of mental and psychological disorders. Cranial electrotherapy stimulation (CES) was applied to the treatment of psychological disorders such as anxiety and depression. We explored the effects of CES combined with biofeedback therapy (BFT) on the psychological state, clinical symptoms, and anorectal function in patients with FC. Methods A total of 74 patients with FC were randomly divided into 2 groups. The control group received BFT. CES combined with BFT was carried out in the experiment group. All patients were assessed using the self-rating anxiety scale (SAS), self-rating depression scale (SDS), and Wexner constipation score at baseline and the end of each course. Anorectal manometry and balloon expulsion tests were performed before and after treatment. Results After treatment, the participants in the experiment group had significantly lower score SAS, SDS, and Wexner constipation scores than the control group (all P < 0.05). The number of successful expulsion in the experiment group was larger than the control group (P = 0.016). Conclusions CES combined with BFT was effective in improving the psychological status of anxiety, depression, and bowel symptoms in patients with FC. (J Neurogastroenterol Motil 2016;22:497-508)
