The hydrothermal reaction of Zn（NO3）2·4H2O, cyclohexane-1,2,3,4,5,6-hexacarboxylic acid hydrate （H6LI·H2O, cis-conformation LI： a,e,a,e,a,e） and 2,2＇-bpy yielded a new coordination polymer [Zn2（H2LII）（2,2＇-bpy）]·2H2O（trans-conformation LII： e,e,e,e,e,e）, which was characterized by single-crystal X-ray diffraction, elemental analysis, IR and XRPD（X-ray powder diffraction）. This complex crystallized in the triclinic system, with P1 space group and parameters a=0.66922（5） nm, b=0.97291（8） nm, c=1.22184（9） nm, α=99.0020（10）°, β=99.1300（10）°, γ=99.1910（10）°, V= 0.76176（10） nm3 and Z=2. The structure is a three-dimensional supramolecular network based on linear coordination chains through π-π stacking and hydrogen bonding interactions. The confromation of the starting ligand H6LI transfromed to the H2LII. The complex emits strong luminescence at room temperature.

The anther is the male reproductive organ in flowering plants. Although some genes were reported to be involved in anther development, the molecular mechanisms underlying the transcriptional regulation of these genes is unclear. Ifr-2 （leaf and flower related-2）, the null allele of Arabidopsis thaliana LFR （LEAF AND FLOWER RELATED）, was male-sterile. The anthers of Ifr-2 plants were defective in sporogenous cell formation, tapetum development, and pollen development. In agreement with these phenotypes, expression studies showed that LFR was expressed in all cell layers of the anther, and that expression was particularly strong in the tapetal cells and pollen grains, Quantitative RT-PCR analysis revealed that LFR is required for the normal transcription of some anther development-related genes, such as AMS, CALS5, and DYT1, MS1 and MS2, and ROXY2. Genetic analysis showed that SPL was epistatic to LFR while LFR was epistatic to DYT1. We propose that LFR may be a crucial component in the regulation of a genetic network that modulates anther development.

Bimetal tubes have useful applications in various industries where service conditions demand more different requirements in the tube core than its outside surface. The recent use of electromagnetic forces to deform or join metallic workpieces at high speeds has undergone rapid growth for materials processing. However, to date, no sufficient systematic understanding of the underlying principles of a subsequent high-speed electromagnetic tube bulging process to manufacture bimetal tubes has been gained. In this work, magnetic pulse cladding of Al/Fe clad bimetal tubes was analyzed by finite element modeling (FEM) using ANSYS software. The validity of FEM analyses was first confirmed by experiments in terms of the deformed shape. Second, the effect of cladding parameters (such as axial feeding being the dominant factor in the multi-step process) on the bulging and thinning behavior of the Al clad tube was presented in detail. Both the numerical simulation and experimental results show that no more than 70% of the bulging-coil length is an appropriate amount for the feeding length to prevent defects from being introduced by non-uniform deformation in the transition zone of the Al clad tube. The distributions of the magnetic flux line, magnetic force, and plastic strain in different cladding steps were then analyzed. It was concluded that during the multi-step cladding process, there was an uneven distribution of the magnetic field force along the transition zone. Consequently, inharmonious plastic deformation behavior occurs, which results in a limited acceleration of the transition zone to a certain impact velocity.

The aim of this paper is to study the determination of the stability regions for continuous-time systems subject to actuator saturation. Using an affine saturation-dependent Lyapunov function, a new method is proposed to obtain the estimation of the domain of attraction of the closed-loop system. A family of linear matrix inequalities （LMIs） that provides sufficient conditions for the existence of this type of Lyapunov function are presented. The results obtained in this paper can reduce the conservativeness compared with the existing ones. Numerical examples are given to illustrate the effectiveness of the proposed results.
