Li, Xin,Liu, Zihui Korean Mathematical Society 2017 대한수학회보 Vol.54 No.4

The t-wise intersection is a useful property of a linear code due to its many applications. Recently, the second author determined the t-wise intersection of a relative two-weight code. By using this result and generalizing the finite projective geometry method, we will present the t-wise intersection of a relative three-weight code and its applications in this paper.

Plant heat shock transcription factors (Hsfs) areimportant regulators of heat shock signal transduction pathway. There are 30 members of the Hsf family in maize, only twoof which, ZmHsf06 and ZmHsf12, belong to subclass A1. Our previous work demonstrated that ZmHsf06-overexpressingArabidopsis lines showed improved tolerance to heat anddrought stresses. In this study, we isolated ZmHsf12 fromyoung leaves of maize (Zea mays L.) using homologouscloning methods. The CDS (coding sequence) of ZmHsf12 is1,494 bp and encodes a putative protein consisting of 497amino acids which possesses domains such as DBD (DNAbindingdomain), OD (oligomerization domain), NLS (nuclearlocalization signal), NES (nuclear export signal), and anAHA (activator) motif. The ZmHsf12-GFP fusion protein islocalized to the cell nucleus. ZmHsf12 was expressed inmany maize organs, and its expression was up-regulated byheat shock. Furthermore, we characterized the function ofZmHsf12 in yeast and Arabidopsis. Yeast cells overexpressingZmHsf12 showed enhanced heat tolerance. ZmHsf12-overexpressing Arabidopsis seedlings displayed significantincreases in both basal and acquired thermotolerance. Comparedto WT seedlings, the ZmHsf12-overexpressing lines displayedboth increased chlorophyll contents and higher survivalrates. Also, the expression of AtHsps was increased higher inthe ZmHsf12-overexpressing Arabidopsis lines after heatstress. The results of our study strongly suggested thatZmHsf12 may take part in plant response to heat stress.

Polytetrafluoroethylene (PTFE) nano-porous membrane has been widely used in various fields due to its excellent thermal stability and chemical stability. However, PTFE nanofiber membranes with simultaneous hydrophobic and oleophobic properties are essential to promote the application of PTFE. Here, based on inorganic/organic nanohybridization, we report a strategy for constructing nanostructures on fibers by adding nanoparticles, such as MOF and ZrO2. The results of FTIR and XRD confirmed MOF was synthesized successfully. At the same time, the SEM results showed UiO-66-(COOH)2 is spherical with an average diameter of 152 nm, and there is no agglomeration, which is suitable for electrospinning. Further, MOF and ZrO2 were payload into PTFE nanofibers. The results of SEM and AFM confirmed nanostructures will be more uniform and pronounced with the increase of UiO-66-(COOH)2 content, and nanostructures are most obvious when the content of UiO-66-(COOH)2 is 15%. The introduced nanostructures can increase the oil contact angle of the PTFE nano-porous membrane to 110° without introducing other groups, and further improve the water contact angle from 133° to 145°. Meanwhile, the introduction of a certain amount of hydrophilia groups can increase the oil contact angle to more than 120°. The simple strategy is of great significance to expand the application of PTFE fiber membrane in dealing with waste water treatment fields.

Effect of Multi-Level Microstructure on Local and Bulk Mechanical Properties in Micro-Injection Molded PC/PET Blend

Jianping Ren,Jing Jiang,Zihui Li,Jianhua Hou,Qian Li 한국고분자학회 2020 Macromolecular Research Vol.28 No.10

This study introduces a method to investigate the relationship between the multi-level microstructures and mechanical properties of polymer blends prepared by micro-injection molding (μIM). Special morphological features were systematically researched. Polycarbonate (PC), poly(ethylene terephthalate) (PET), and PC/PET microparts all exhibit typical “skin-core” morphologies. The thickness of the core layer is much greater than that of the skin layer, and the thickness of the skin layer gradually decreases along the flow direction. Photoacoustic Fourier transform infrared spectroscopy records reveal that the PC molecular chain has the biggest orientation degree, followed by PC/PET and PET chains under the same μIM processing conditions. Moreover, the molecular chains orientation in the skin layer is more than 50% that in the core layer. Nanoindentation tests are conducted to study local mechanical properties. The higher modulus in the shear layer is affected to a greater extent by high shear action in comparison with the frozen and core layers. Uniaxial tensile testing demonstrates that the tensile strength of PC/PET micropart is 15.5% higher than that of the PET micropart, while the toughness is 16% higher than that of the PC microparts. In-situ, high- speed tensile imaging, combined with scanning electron microscopy micrographs of the fracture section, are used to study the fracture behaviors of the microparts. The results gathered in this paper may provide a theoretical basis and data to support the feasibility and efficiency of micro-injection molded polymer blends.

To improve the performance of blanket: maximizing the tritium breeding rate (TBR) for tritium selfsufficiency, and minimizing the Dose of backplate for radiation protection, most previous studies are based on manual corrections to adjust the blanket structure to achieve optimization design, but it is difficult to find an optimal structure and tends to be trapped by local optimizations as it involves multiphysics field design, which is also inefficient and time-consuming process. The artificial intelligence (AI) maybe is a potential method for the optimization design of the blanket. So, this paper aims to develop an intelligent optimization method based on an improved multi-objective NSGA-III algorithm and an adaptive BP neural network to solve these problems mentioned above. This method has been applied on optimizing the radial arrangement of a conceptual design of CFETR HCSB blanket. Finally, a series of optimal radial arrangements are obtained under the constraints that the temperature of each component of the blanket does not exceed the limit and the radial length remains unchanged, the efficiency of the blanket optimization design is significantly improved. This study will provide a clue and inspiration for the application of artificial intelligence technology in the optimization design of blanket.

Objective: Parathyroid hormone like hormone (PTHLH), as an essential factor for bone growth, is involved in a variety of physiological processes. The aim of this study was to explore the role of PTHLH gene in the growth of antlers.Methods: The coding sequence (CDS) of PTHLH gene cDNA was obtained by cloning in sika deer (Cervus nippon), and the bioinformatics was analyzed. The quantitative real-time polymerase chain reaction (qRT-PCR) was used to analyze the differences expression of PTHLH mRNA in different tissues of the antler tip at different growth periods (early period, EP; middle period, MP; late period, LP).Results: The CDS of PTHLH gene was 534 bp in length and encoded 177 amino acids. Predictive analysis results revealed that the PTHLH protein was a hydrophilic protein without transmembrane structure, with its secondary structure consisting mainly of random coil. The PTHLH protein of sika deer had the identity of 98.31%, 96.82%, 96.05%, and 94.92% with Cervus canadensis, Bos mutus, Oryx dammah and Budorcas taxicolor, which were highly conserved among the artiodactyls. The qRT-PCR results showed that PTHLH mRNA had a unique spatio-temporal expression pattern in antlers. In the dermis, precartilage, and cartilage tissues, the expression of PTHLH mRNA was extremely significantly higher in MP than in EP, LP (p<0.01). In the mesenchyme tissue, the expression of PTHLH mRNA in MP was significantly higher than that of EP (p<0.05), but extremely significantly lower than that of LP (p<0.01). The expression of PTHLH mRNA in antler tip tissues at all growth periods had approximately the same trend, that is, from distal to basal, it was first downregulated from the dermis to the mesenchyme and then continuously up-regulated to the cartilage tissue.Conclusion: PTHLH gene may promote the rapid growth of antler mainly through its extensive regulatory effect on the antler tip tissue.
