The homoclinic bifurcations in four dimensional vector fields are investigated by setting up a local coordinates near the homoclinic orbit. This homoclinic orbit is nonprincipal in the meanings that its positive semi-orbit takes orbit flip and its unstable foliation takes inclination flip. The existence, nonexistence, uniqueness and coexistence of the 1-homoclinic orbit and the 1-periodic orbit are studied. The existence of the twofold periodic orbit and three-fold periodic orbit are also obtained.

AIM: To study the association between APOE polymorphisms and cerebral infarction through a case-control study among the Chinese Han population. METHODS: First-ever cerebral infarction patients (n=2.6) whose ages ranged from 40 to 60 years old were recruited from department of Neurology, Zhongshan Hospital, Shanghai, and Zhejiang Chinese Traditional Medicine Hospital, Zhejiang, China. Unrelated healthy controls (n=2.1) were selected from the general population in the same area with similar age and sex distribution. APOE was amplified by one-stage PCR using the forward primer: 5'-GGC ACG GCT GTC CAA GGA GCT-3' and reverse primer: 5'-GAT GGC GCTGAG GCC GCG CT-3'. The PCR product was digested directly with 5 U of CfoI and separated by a 2. % polyacryla- mide (acrylamide: bis-acrylamide=2.:1) nondenaturing gel. RESULTS: Both cerebral infarction patient and control groups were in Hardy-Weinberg equilibrium. The allele frequency of APOE*2. APOE*3, and APOE*4 was 4.6 %, 81.9 %, and 13.5 % respectively in the patients with cerebral infarction; 5.7 %, 87.3 %, and 7.0 % respectively in the healthy control group. Compared with APOE3/3 subjects, APOE4/4 carriers had a 2.1-fold risk of cerebral infarction (odds ratio 2.1, 95 % confidence limits 1.3 to 3.4). The allele frequency of APOE*4 in the cerebral infarction patient group was significantly higher than that in the control group (13.5 % vs 7.0 %; P=0.002.. CONCLUSION: APOE 4 is a risk factor for cerebral infarction among the Chinese Han population.

Based on the propagation theory of partially coherent light in the space-frequency domain, the anomalous spectral behavior and spectral switches in the far field of partially coherent and polychromatic light diffracted at an aperture are studied. It is shown that, as compared with spatially fully coherent and polychromatic light whose spectral anomalies are induced only by aperture diffraction, the spectral anomalies and spectral switches of partially coherent and polychromatic light depend on the aperture diffraction, spatial correlationβ and bandwidth of the original spectrum. Detailed numerical calculations are made to illustrate the behavior of spectral switches of partially coherent and polychromatic light, and the results for spatially fully coherent and polychromatic light are treated as a special case ofβ=1 and included in our theory.

The conformational entropy S and free energy F were calculated by exact enumeration of polysilane chain up to 2. segments with excluded volume (EV) and long-range van der Waals (VW) interaction. A nonlinear relation between SEV+VW and chain length n was found though S-EV was found to vary linearly with n. We found that the second-order transition temperature of polysilane chain with VW interaction increases with the increase of chain length, while that of polysilane chain without VW interaction is chain length independent. Moreover, the free energies FEV+VW and F-EV are both linearly related with n, and FEV+VW < F-EV for all temperatures.
