Abstract

To reveal risk problems of youth innovation and entrepreneurship under the Internet crowdfunding, this paper proposed the youth innovation and entrepreneurship risk indicator system under Internet crowdfunding from several levels such as the Internet crowdfunding platform of entrepreneurial potential, and education. The risk identification method of case analysis was formed through combining the construction of index system with Bayesian inference, thus it can realize the identification of risks and conduction paths rapidly and dynamically, and provide optimization advice for the healthy development and efficient integration of the Internet crowdfunding and the innovation and entrepreneurship.

The objective of this study was to identify critical genes and pathways related to the carcinogenesis of BCC and gain more insights into the underlying molecular mechanisms of BCC.Materials and methods: The gene expression profiles of GSE7553 and GSE103439 were downloaded from the Gene Expression Omnibus database with 19 tumors and 6 normal skin tissues. Differentially expressed genes (DEGs) were screened between BCC samples and normal tissues, followed by gene ontology and Kyoto Encyclopedia of Genes and Genomes pathway enrichment analysis. Subsequently, protein–protein interaction (PPI) network was constructed for these DEGs, and module analysis was performed.Results: A total of 313 DEGs were obtained. Among them, 222 genes were upregulated and 91 genes were downregulated. Enrichment analysis indicated that the upregulated genes were significantly enriched in cell cycle and mitosis, while the downregulated genes were mainly associated with unsaturated fatty acid metabolic process and cell differentiation. In addition, TOP2A, CDK1, and CCNB1 were identified as the top three hub genes ranked by degrees in the PPI network. Meanwhile, three subnetworks were derived, which indicated t

Abstract

[(C6H5CH2C5H4)2GdCl.THF]2 (1) and (C6H5CH2C5H4)2ErCl.THF (2) were prepared by the reaction of LnCl3 (LnGd, Er) with benzylcyclopentadienyl sodium in THF and characterized by elemental analysis, IR, 1H NMR, 13C NMR, MS and thermal gravimetry. The crystal structures of both compounds were determined. Complex 1 is dimeric and its structure belongs to the monoclinic, P21/c space group with a=1.1432(2), b=1.2978(2), c=1.7604(3) nm, β=108.75(2), V=2.4732(9) nm3, Z=2(four monomers), Dc“1.54 g.cm−3. R=0.0342 and Rw“0.0362. Complex 2 is monomer and its structure belongs to the orthorhombic, P212121 space group with a=0.8645(2), b=1.1394(3), c=2.5289(4) nm, V=2.4919(9) nm3, Z=4, Dc“1.56 g.cm−3. R=0.0514, Rw“0.0529. The determination of the crystal structure shows that in complex 1 the benzyl groups on the cyclopentadienyls coordinated to Gd3+ are located in the opposite direction (139°); in complex 2 the benzyl groups on the cyclopentadienyls coordinated to Er3+ are located in the same direction (6.5°).

Abstract

Reaction of anhydrous ytterbium trichlorides with 2 equiv. of cyclopentylindenyl lithium in THF solution, followed by removal of the solvent MO. crystallization of the product from diethyl ether, affords a crystal complex of the composition (C5H9C9H6)(2)Yb(mu-Cl)(2)Li(Et2O)(2). Crystallographic analysis shows that the ytterbium coordinated by two cyclopentylindenyl rings and lithium surrounded by two ether molecules are bridged by the two chlorine atoms and Yb, U and two chlorine atoms form a plane.

Abstract

Low-lying structures of water cationic clusters and the compounds with the OH radical have become a hot topic in recent years. We here investigate the cluster H2O10+ and calculate its ideal structures by the quantum chemical calculation together with the particle swarm optimization method. We analyzed the properties of the obtained lower-energy isomers of H2O10+. Their energies are further re-optimized and demonstrated at three different methods with two basis sets. Based on our numerical calculations, a new cage-like structure of H2O10+ with the lowest energy is obtained at MP2/aug-cc-pVDZ level. Our results showed the comparison of energy order at different conditions and demonstrated the influence of temperature on the relative Gibbs energy and IR spectra. Moreover, we also contained the molecule orbitals to discuss the stability of these representative isomers. [ABSTRACT FROM AUTHOR]

Abstract

We have performed comprehensive first-principle calculations to investigate the structural, electronic, magnetic, elastic and optical properties of the tetragonal zircon-type CeVO4. The local density approximation plus U (LDA+U) and generalized gradient approximation plus U (GGA+U) methods are used to interpret the strong Coulomb repulsion among the localized Ce 4f electrons. Without the effective U parameters, the obtained ground state of the ferromagnetic (FM) metal is not consistent with the experimental result. However, we can get the antiferromagnetic (AFM2: the magnetic ground state) insulating ground state for CeVO4 by LDA+U and GGA+U. It reveals that the result is in agreement with the experiment. For AFM2 CeVO4, the dependence of properties on the U parameters has been studied in detail. The effect of spin–orbit coupling (SOC) has also been investigated in detail. The demonstrated properties include volume, lattice parameters, bandgap, the density of states (DOS) and spin magnetic moment of Ce atom. With the Hubbard U parameter around 6 eV, the lattice parameters (a=7.396 Å, V=351.82 Å3, c/a=0.874), bulk modulus B0 (121 GPa), insulating gap (2.157 eV) and magnetic moment (0.97  μ B per Ce atom) are consistent with the experiments and other theoretical results. Besides, the elasticity-related properties and optical properties have also been calculated for U=0,2,4 and 6 eV. [ABSTRACT FROM AUTHOR]
