{μ-[2-(Dimethylamino)phenyl](2-fluorophenyl)methanolato}pentamethyldialuminum(III)
Aihong Gao,Qing Su,Ying Mu
Acta Crystallographica Section E , 2009, DOI: 10.1107/s1600536809012252
Abstract: Each of the Al atoms in the title compound, [Al2(CH3)5(C15H15FNO)], is four-coordinated in a distorted tetrahedral geometry. The dimethylaluminium centre is bound by the N and the O atoms of the (2-dimethylaminophenyl)(2-fluorophenyl)methanolate ligand. The second Al atom is bound by the methanolate O atom and by three methyl C atoms. The crystal studied was a racemic twin with a 0.4 (2):0.6 (2) domain ratio.

Abstract: The title dinuclear titanocene, [Ti2(C8H9O)(C18H25Si)2Cl3O], contains one Ti atom tetrahedrally coordinated by two Cl atoms, a bridging O atom and the substituted cyclopentadienyl ligand, and another Ti atom tetrahedrally coordinated by a Cl atom, a bridging O atom, the 2,6-dimethylphenolate ligand and the substituted cyclopentadienyl ligand. The bridging O atom lies on a twofold rotation axis.

Yanyu Zhang,Qiaolin Wu,Ying Mu
Acta Crystallographica Section E , 2012, DOI: 10.1107/s1600536811053773
Abstract: In the title compound, [FeCl2(C34H36N4)], the FeII ion is coordinated by two Cl atoms and by two N atoms from a (1R,2R)-N,N′-bis[2-(N-methylanilino)benzylidene]cyclohexane-1,2-diamine ligand in a distorted tetrahedral geometry. The molecule has approximate C2 point symmetry. The dihedral angles between the phenyl and benzene rings on either side of the ligand are 64.56 (14) and 65.61 (13)°.
Increased sensitivity to drought stress in atlon4 Arabidopsis mutant
XiaoYi Li,Ying Mu,XuWu Sun,LiXin Zhang
Chinese Science Bulletin , 2010, DOI: 10.1007/s11434-010-4166-4
Abstract: The ATP-dependent serine protease Lon belongs to the AAA+ superfamily, which is widely distributed in bacteria, archaea, and eukaryotic cells. Lon participates in the regulation of numerous physiological processes and gene expression via degrading various unstable and non-native regulators. In this study, we showed that the Arabidopsis atlon4 mutant is more sensitive to drought stress than wild-type plants. Compared with wild-type plants, atlon4 mutant plants showed increased water loss, decreased water use efficiency, and impaired stomatal closure in drought stress conditions.
5-{2-(4-Chlorophenyl)-1-[2-(4-chlorophenyl)-1-(3,4,5-trimethoxyphenyl)ethoxy]ethyl}-1,2,3-trimethoxybenzene

Acta Crystallographica Section E , 2012, DOI: 10.1107/s1600536812008823
Abstract: The title compound, C34H36Cl2O7, is a by-product from the reaction of 4-chlorobenzylzinc chloride with 3,4,5-trimethoxybenzaldehyde. In each of the two 1,2-diphenylethyl moieties, the two benzene rings are arranged in a trans conformation and make Car—C—C—Car torsion angles of 163.64 (19) and 174.43 (18)°. The crystal structure is stabilized by van der Waals interactions only.
[(E)-10-(2,6-Dimethylphenylimino)-9-methyl-9,10-dihydrophenanthren-9-olato]pentamethyldialuminum(III)
Bo Gao,Qing Su,Wei Gao,Ying Mu
Acta Crystallographica Section E , 2011, DOI: 10.1107/s1600536811036312
Abstract: The two Al atoms in the title compound, [Al2(CH3)5(C23H20NO)], are four-coordinated in a distorted tetrahedral environment. The coordination of one Al atom includes three methyl-C atoms and the O atom from the ligand, whereas the second Al atom is surrounded by the O atom and one N atom from the ligand as well as by two methyl-C atoms. In the ligand, the dihedral angle between the two phenyl rings in the 9,10-dihydrophenanthren unit is 20.64 (12)°.

Acta Crystallographica Section E , 2011, DOI: 10.1107/s1600536811017107
Abstract: In the title compound, C13H16N4OS3, a thienopyridinederivative, the tetrahydropyridine ring exhibits a half-chair conformation, and the folded conformation of the molecule is defined by the N—C—C—N torsion angle of 78.85 (16)°.

Acta Crystallographica Section E , 2009, DOI: 10.1107/s1600536809037969
Abstract: The title anilide–imine compound, C24H26N2O, features an intramolecular N—H...N hydrogen bond involving the imine and anilide groups to generate an S(6) ring motif. The molecule displays an E configuration about the imine C=N double bond, with the dihedral angle between the two benzene rings being 86.5°. The packing is stabilized by three different C—H...π interactions.
Relativistic ideal Bose gas in Harmonic traps
Xiang-Mu Kong,Ying Wang,Cong-Fei Du
Physics , 2011,
Abstract: Using semiclassical approximation method, Bose-Einstein condensation (BEC) of a relativistic ideal boson gas (RIBG) with and without antibosons in three-dimensional (3-D) harmonic traps is investigated. The BEC transition temperature T_{c} and the Helmholtz free energy at T_{c} are calculated. The effect of the rest mass of the boson on the properties of the system is also studied. We find that T_{c} of RIBG is higher than that of the nonrelativistic approximation. The RIBG with antibosons is also investigated and it is found that the Helmholtz free energy of the system with antibosons at T_{c} is lower than that of the system without antibosons. It implies that the system with antibosons is more stable.
Nonhyperbolic Dehn fillings on hyperbolic 3-manifolds
Mario Eudave-Mu?oz,Ying-Qing Wu
Mathematics , 1997,
Abstract: We give three infinite families of examples of nonhyperbolic Dehn fillings on hyperbolic manifolds. A manifold in the first family admits two Dehn fillings of distance two apart, one of which is toroidal and annular, and the other is reducible and $\partial$-reducible. A manifold in the second family has boundary consisting of two tori, and admits two reducible Dehn fillings. A manifold in the third family admits a toroidal filling and a reducible filling with distance 3 apart. These examples establish the virtual bounds for distances between certain types of nonhyperbolic Dehn fillings.
