The discovery of superconductivity in quasi-one-dimensional Cr-based pnictides A2Cr3As3（A = alkali metals） has generated considerable research interest, primarily owing to their reduced dimensionality, significant electron correlations,and possible unconventional superconductivity. The upper critical field（Hc2） provides important information on the superconducting pairing. In this paper, we first briefly overview the latest research progress on the Cr-based ***, we introduce typical Hc2（T） behaviors of type-II superconductors in relation with the pair-breaking *** a description of the measurement method for Hc2, we focus on the analysis of Hc2 data, especially for the temperature and angle dependence, in K2Cr3As3 crystals. The result indicates（i） an absence of Pauli-paramagnetic pair breaking for field perpendicular to the Cr3As3 chains, and（ii） a unique threefold modulation for the in-plane Hc2Φ profile. Finally we conclude with remarks on the possible unconventional superconducting pairing symmetry.

Heat stress is a severe environmental factor that significantly reduces plant growth and delays develop-ment. Heat stress factors （HSFs） are a class of transcription factors that are synthesized rapidly in response to elevations in temperature and are responsible for the transcription of many heat stress-responsive genes including those encoding heat shock proteins （HSPs）. There are 21 HSFs in Arabidopsis, and recent studies have established that the HSFA1 family members are master regulators for the remaining HSFs. However, very little is known about upstream molecular factors that control the expression of HSFA1 genes and other HSF genes under heat stress. Through a forward genetic analysis, we identified RCF3, a K homology （KH） domain-containing nuclear-localized putative RNA-binding protein. RCF3 is a neg- ative regulator of most HSFs, including HSFAla, HSFAlb, and HSFAld. In contrast, RCF3 positively controls the expression of HSFAle, HSFA3, HSFAg, HSFB3, and DREB2C. Consistently with the overall increased accumulation of heat-responsive genes, the rcf3 mutant plants are more tolerant than the wild-type to heat stress. Together, our results suggest that a KH domain-containing putative RNA-binding protein RCF3 is an important upstream regulator for heat stress-responsive gene expression and thermotolerance in Arabidopsis.

Aiming at the influences of poor contact at carbon nanotube (CNT)/electrode interface on luminescence stability in printed CNT film, a new co-sintering process for cathode fabrication was presented to improve the luminescent stability of fully printed CNT-FED. By co-sintering the printed silver and CNT layers, CNTs geometrically matched with Ag surface and/or embedded into Ag layer at the bottom of the co-sintered film, large CNTs block and bulk silver nested each other at the top of the co-sintered film. All these structures increased the contact area at CNT/Ag interface, which could increase the probability of forming ohmic contact at CNT/Ag interface. The luminescent stability of printed CNT-FED with co-sintered cathode could be improved as 5.6 times high as that of common devices.

In this article, the least square constant modulus algorithm （LSCMA） is combined with the subspace approach and a LSCM_SUB （Subspace） blind adaptive multiuser detection in multipath code division multiple access （CDMA） channels is presented. The poor performance of LSCMA in the low signal to noise ratio （SNR） is improved by the LSCM_SUB algorithm. The performance of the proposed LSCM_SUB algorithm is compared with that of LSCMA. Simulation results show that the LSCM_SUB algorithm is superior to the LSCMA, especially in the low SNR.

Commwarrior worm is capable of spreading through both Bluetooth and multimedia messaging service （MMS） in smart phone networks. According to the propagation characteristics of Bluetooth and MMS, we built the susceptibleexposed-infected-recovered-dormancy （SEIRD） model for the Bluetooth and MMS hybrid spread mode and performed the stability analysis. The simulation results show good correlation with our theoretical analysis and demonstrate the effectiveness of this dynamic propagation model. On the basis of the SEIRD model, we further discuss at length the influence of the propagation parameters such as user gather density in groups, moving velocity of smart phone, the time for worm to replicate itself, and other interrelated parameters on the propagation of the virus. On the basis of these analytical and simulation results, some feasible control strategies will be proposed to restrain the spread of mobile worm such as commwarrior on smart phone network.

The selection of meat quality has received considerable focus in chicken breeding. This study was aimed at investigating the effect of CAPN1 gene on meat quality traits in chicken populations. Primer pairs for 3 UTR in CAPN1 were designed from database of chicken genomic sequence. Polymorphisms were detected using PCR-SSCP and DNA sequencing. A mutation at position 9 950 nt （G/A, locus A） was found among individuals in each population. The allele and genotype frequencies significantly differed among eight lines with higher frequencies of allele A2 and genotype AIA2 （P〈0.01）. The least square analysis showed that there was significant difference （P 〈 0.05） in muscle fiber density and some carcass traits among genotypes and that the breast muscle fiber density （BFD） of birds ofAIA1 genotype was significantly higher （P〈0.05） than that of birds ofA2A2 genotype. It was concluded that the CAPN1 gene was the major gene affecting the muscle fiber traits of chicken or was linked with the major gene. These results were useful for studying the molecular mechanism that influences meat traits and were used as the base of molecular-assisted selection to meat quality traits. So, this site may be a potential marker affecting the muscle traits of chickens.
