Name Disambiguation Method Based on Attribute Match and Link Analysis  [PDF]
Yu-Feng Yao
Journal of Software Engineering and Applications (JSEA) , 2012, DOI: 10.4236/jsea.2012.51005
Abstract: A name disambiguation method is proposed based on attribute match and link analysis applying in the field of insurance. Aiming at the former name disambiguation methods such as text clustering method needs to be considered in a lot of useless words, a new name disambiguation method is advanced. Firstly, the same attribute matching is applied, merging the identity of a successful match, secondly, the link analysis is used, structural analysis of customers network is analyzed, Finally, the same cooperating information is merged. Experiment results show that the proposed method can realize name disambiguation successfully.
An Improved Name Disambiguation Method Based on Atom Cluster  [PDF]
Yu-Feng Yao
Communications and Network (CN) , 2012, DOI: 10.4236/cn.2012.41004
Abstract: An improved name disambiguation method based on atom cluster. Aiming at the method of character-related properties of similarity based on information extraction depends on the character information, a new name disambiguation method is proposed, and improved k-means algorism for name disambiguation is proposed in this paper. The cluster analysis cluster is introduced to the name disambiguation process. Experiment results show that the proposed method having the high implementation efficiency and can distinguish the different people with the same name.
Mixing-induced CP violating sources for electroweak baryogenesis
Zhou, Yu-Feng
High Energy Physics - Phenomenology , 2008, DOI: 10.1063/1.3052010
Abstract: The effects of flavor mixing in electroweak baryogenesis is investigated in a generalized semiclassical WKB approach. Through calculating the nonadiabatic corrections to the particle currents it is shown that extra CP violation sources arise from the off-diagonal part of the equation of motion of particles moving inside the bubble wall. The numerical importance of the mixing-induced source is discussed in the Minimal Supersymmetric Standard Model and compared with the source term induced by semiclassical force.
Methyl 3-(2-furylmethylidene)carbazate
Yu-Feng Li
Acta Crystallographica Section E , 2011, DOI: 10.1107/s1600536810051019
Abstract: The asymmetric unit of the title compound, C7H8N2O3, contains two approximately planar molecules (r.m.s. deviations = 0.058 and 0.070 ). In the crystal, molecules are linked into [010] chains by way of alternating N—H...O and N—H...(N,O) hydrogen-bond linkages.
1-(2,4-Dichlorobenzylidene)-4-ethylthiosemicarbazide
Yu-Feng Li
Acta Crystallographica Section E , 2010, DOI: 10.1107/s1600536810035671
Abstract: The title compound, C10H11Cl2N3S, was prepared by the reaction of 4-ethylthiosemicarbazide and 2,4-dichlorobenzaldehyde. It is approximately planar, the dihedral angle between the benzene ring and the thiourea unit being 8.43 (18)°. In the crystal, inversion dimers linked by pairs of N—H...S hydrogen bonds generate R22(8) loops.
1-(4-Methoxybenzylidene)-4-methylthiosemicarbazide
Yu-Feng Li
Acta Crystallographica Section E , 2010, DOI: 10.1107/s1600536810038882
Abstract: The title compound, C10H13N3OS, was prepared by the reaction of 4-methoxybenzaldehyde and 4-methylthiosemicarbazide. The dihedral angle between the benzene ring and the thiourea unit is 8.64 (7)° and an intramolecular N—H...N hydrogen bond generates an S(5) ring. In the crystal, inversion dimers linked by pairs of N—H...S hydrogen bonds generate R22(8) loops. The dimers are linked into (001) sheets by further N—H...S links.
1-(4-Chlorobenzylidene)-4-ethylthiosemicarbazide
Yu-Feng Li
Acta Crystallographica Section E , 2010, DOI: 10.1107/s1600536810047446
Abstract: In the title compound, C10H12ClN3S, the dihedral angle between the benzene ring and the thiourea unit is 2.35 (19)°. In the crystal, inversion dimers linked by pairs of N—H...S hydrogen bonds generate R22(8) loops.
4-Methyl-1-(4-methylbenzylidene)thiosemicarbazide
Yu-Feng Li
Acta Crystallographica Section E , 2010, DOI: 10.1107/s1600536810040663
Abstract: The title compound, C10H13N3S, prepared by the reaction of 4-methylbenzaldehyde and 4-methylthiosemicarbazide, is approximately planar (r.m.s. deviation for the non-H atoms = 0.032 ). Its conformation is stabilized by an intramolecular N—H...N hydrogen bond, generating an S(5) ring. In the crystal, inversion dimers linked by pairs of N—H...S hydrogen bonds occur. Further weak N—H...S links connect the dimers into (100) sheets.
N-p-Tolylpyrrolidine-1-carboxamide
Yu-Feng Li
Acta Crystallographica Section E , 2012, DOI: 10.1107/s1600536812013578
Abstract: In the title molecule, C12H16N2O, the pyrrolidine ring has a half-chair conformation. In the crystal, molecules are linked into C(4) chains along [001] by N—H...O hydrogen bonds.
Guanidinium bromide–18-crown-6 (2/1)
Yu-feng Wang
Acta Crystallographica Section E , 2012, DOI: 10.1107/s1600536812017394
Abstract: In the title compound, 2CH6N3+·2Br ·C12H24O6, the 18-crown-6 molecule lies about an inversion center, whereas the guanidinium cation and bromide anion are in general positions. The guanidinium cations link with the bromide anions and the crown ether molecules via N—H...O and N—H...Br hydrogen bonds, thus forming a three-dimensional network.
