In this paper, a facile synthetic approach to prepare CdTe quantum dots（QDs） with high luminescence via a one-pot microwave irradiation reaction route using 3-mercaptopropionic acid（MPA） as both a sodium tellurite re- ducer and a capping molecule was described, and the mechanism of the formation of CdTe QDs was elucidated. In this approach, CdTe QDs with six different emission wavelengths of 553, 567, 577, 595, 608 and 615 nm were ob- tained via changing the refluxing time and the quantum yields（QY） of these QDs were 40.6%, 55.3%, 63.6%, 43.4%, 37.4% and 29.7%, respectively. The characterization results of X-ray powder diffraction（XRD） and transmission electron microscopy（TEM） indicate that the obtained QDs have a pure cubic zinc blended structure with a spherical shape. No toxic gases were released during the preparation process, indicating that the method is relatively fast, cheap and environmentally friendly.

Armchair carbon nanocoils (CNCs) with different geometric parameters are constructed and optimized using a tight-binding (TB) total energy model. The quantum conductance of these nanocoils is simulated employing a π-orbital TB model incorporated with the non-equilibrium Green's function theory. Compared with the perfect armchair carbon nanotubes (CNTs) and armchair CNTs with only Stone-Wales (SW) defects, the quantum conductance spectra of the armchair CNCs present distinct gaps around the Fermi level, which are mainly originated from the existence of sp3 carbon in the three-dimensional spiral structures. Moreover, the detailed conductance spectra of the armchair CNCs depend sensitively on their geometric parameters, such as tubular diameter and block-block distance.

Aiming at the problem that virtual machine information cannot be extracted incompletely, we extend the typical information extraction model of virtual machine and propose a perception mechanism in virtualization system based on storage covert channel to overcome the affection of the semantic gap. Taking advantage of undetectability of the covert channel, a secure channel is established between Guest and virtual machine monitor to pass data directly. The Guest machine can pass the control information of malicious process to virtual machine monitor by using the VMCALL instruction and shared memory. By parsing critical information in process control structure, virtual machine monitor can terminate the malicious processes. The test results show that the proposed mechanism can clear the user-level malicious programs in the virtual machine effectively and covertly. Meanwhile, its performance overhead is about the same as that of other mainstream monitoring mode.

THE fine disseminated gold deposits in Yunnan-Guizhou-Guangxi triangle area in S. China occur in thesedimentary rocks and are not relative to magmatism in space and genesis. Many authors have studiedthese deposits and obtained different conclusions. This note makes the first systematic study on sulfur isotope compositions to further discuss possible sources of ore-forming materials. 1 Sulfur isotope composition Figure 1 shows variations of sulfur isotope compositions of 232 sulfide separats from various depositsand their host rocks. S S values of pyrite from Mid-Triassic Banna Formation strata in the Jinya ore district can be divided into two groups: -7.4‰ to -6.4‰ and 2.7‰ to 14.1‰. Pyrite from the Jinyadeposits has δ34S values of -7.2‰-1.9‰, stibnite -6.7‰- -4.9‰ and arsenopyrite -4.1‰-

成纤维细胞生长因子23(FGF23)是钙磷代谢平衡研究的热点之一。FGF23主要通过FGF受体(FGFR)及其共受体蛋白klotho作用于肾脏、甲状腺等靶器官,与甲状旁腺激素、1,25(OH)2D3、klotho蛋白之间关系密切,共同调节机体钙磷平衡。在慢性肾脏病(CKD)患者中,FGF23水平明显升高,并与进展为终末期肾病、心血管事件、死亡相关,部分归咎于FGF23通过klotho非依赖途径导致的心脏直接脱靶毒效应。临床上提出了一系列可能降低FGF23水平的措施,这些措施可能改善CKD患者预后。
