A low-power and low-cost advanced encryption standard （AES） coprocessor is proposed for Zigbee system-on-a-chip （SoC） design. The cost and power consumption of the proposed AES coprocessor are reduced considerably by optimizing the architectures of SubBytes/InvSubBytes and MixColumns/InvMixColumns, integrating the encryption and decryption procedures together by the method of resource sharing, and using the hierarchical power management strategy based on finite state machine （FSM） and clock gating （CG） technologies. Based on SMIC 0.18 μm complementary metal oxide semiconductor （CMOS） technology, the scale of the AES coprocessor is only about 10.5 kgate, the corresponding power consumption is 69.1 μW/MHz, and the throughput is 32 Mb/s, which is reasonable and sufficient for Zigbee system. Compared with other designs, the proposed architecture consumes less power and fewer hardware resources, which is conducive to the Zigbee system and other portable devices.

We propose a three-species aggregation model with catalysis-driven decomposition. Based on the mean-field rate equations, we investigate the evoIution behavior of the system with the size-dependent catalysis-driven decomposition rate J（i; j; k） = Jijk^v and the constant aggregation rates. The results show that the cluster size distribution of the species without decomposition can always obey the conventional scaling law in the case of 0 ≤v ≤ 1, while the kinetic evolution of the decomposed species depends crucially on the index v. Moreover, the total size of the species without decomposition can keep a nonzero value at large times, while the total size of the decomposed species decreases exponentially with time and vanishes finally.

This study was undertaken to dissect quantitative trait loci （QTLs） controlling yield traits on the short arm of rice chromosome 6. A residual heterozygous line that carries a heterozygous segment extending from RM587 to RM19784 on the short arm of rice chromosome 6 was selected from an F7 population of the indica rice cross Zhenshan 97B/Milyang 46. An F2：3 population consisting of 221 lines was derived and grown in two trial sites. Six yield traits including number of panicles per plant, number of filled grains per panicle, total number of spikelets per panicle, spikelet fertility, 1 000-grain weight, and grain yield per plant were measured. An SSR marker linkage map was constructed and employed to determine QTLs for yield traits with Windows QTL Cartographer 2.5. QTLs were detected in the target interval for all the traits analyzed except NP, with phenotypic variance explained by a single QTL ranging between 6.3% and 35.2%. Most of the QTLs for yield components acted as additive QTLs, while the three QTLs for grain yield had dominance degrees of 1.65, 0.84, and -0.42, respectively. It was indicated that three or more QTLs for yield traits were located in the target region. The genetic action mode, the direction of the QTL effect, and the magnitude of the QTL effect varied among different QTLs for a given trait, and among QTLs for different traits that were located in the same interval.

Two isostructural tellurite phosphates Ni2MIITeIV2O2(PO4)2(OH)4(MII= Ni, Zn) havebeen synthe-sized via hydrothermal method. Both of them crystalize in monoclinic space group C2/m(No. 12). For Ni2ZnTeIV2O2(PO4)2(OH)4,a= 19.3247(10),b= 5.9697(3), c= 4.7737(2)Å, β= 103.637(5)°, V= 535.18(5)Å3, Z= 2, Mr= 727.94, S= 1.103, Dc= 4.517 g-cm-3, μ(MoKα) = 11.434 mm-1and F(000) = 672, the final R= 0.0369and wR= 0.1086for 639 observed reflections with I> 2σ(I). The crystal structure of Ni2MIITeIV2O2(PO4)2(OH)4(MII= Ni, Zn) features a 3Dframework composed of [Ni2O2(PO4)2]6-layers interconnected by [MTe2O2(OH)4]2+single chains. Different magnetic susceptibility results at low temperature of the two title compounds confirm that Zn(1) completely occupies the Ni(2) position but not partially substitutesboth Ni(1) and Ni(2) positionatoms. Additionally, the acentric TeO3(OH)2tetragonal pyramids are aligned in an antiparallel manner,resultinginthe crystallization of centrosymmetric (C2/m) crystal structureinstead ofthenon-centrosymmetric crystal structure. The investigation of the origin of centrosymmetric crystal structurewith strong dipole moment units provides deeper understandingfor future rational design for non-centrosymmetric crystal structure. © 2021 Fujian Institute of Research of the Structure of Matter.
