The quantum chemical method is employed to study the enantioselective reduction of imine with borane catalyzed by chiral oxazaborolidine. All the structures are optimized completely at the B3LYP/6-31G(d) level. The catalysis property of oxazaborolidine is notable. The reduction goes mainly through the formations of the catalyst-borane adduct, the catalyst-borane-imine adduct, and the catalyst-amidoborane adduct and the dissociation of the catalyst-amidoborane adduct with the regeneration of the catalyst. The controlling step for the reduction is the dissociation of the catalyst-amidoborane adduct. The main reduced product predicted theoretically is (R )-sec- ondary amine, which is in agreement with the experiment.

With the progress of science and technology, human beings explore the energy underground with thousands of meters. As a thermophysical parameter, initial formation temperature （IFT） plays an essential role in deep well engineering. However, it is not easy to predict the IFT accurately before drilling. This work uses a new method to analyze the effect factors of the underground temperature field, and assumes an artificial surface to eliminate the disturbance of the human errors and equipment errors on the surface temperature and thermal conductivity. Considering different distributions of the formation thermal conductivity and the rock radiogenic heat production, an optimized model was established. With this model, the paper predicted the bottom temperature of the main hole of the Chinese Continental Scientific Drilling （CCSD） as 132.80 ℃ at 4 725 m depth with 0.5% error. When the thermal conduction is dominant in the formation, this simple method can predict the IFT distribution effectively for deep well in the exploration stage. However, it is almost impossible to avoid aquifers in the formation of drilling deep well, an existing drillhole including groundwater is needed to predict for testing the model＇s accuracy.

BACKGROUNDOsteofbrous dysplasia （OFD） is a developmental ske-letal disorder, and cases with a giant affected area in the pelvis are *** SUMMARYIn this case report, a 48-year-old man presented with a large tumor in the right iliac region that turned out to be OFD. The patient had rebound tenderness in his right hip. After radiography examination, magnetic resonance imaging examinations and some physical examination, extensive bone destruction in the right ilium was confirmed. Moreover, changes in bone mi-neral density and peripheral cortical bone sclerosis with surrounding soft tissue swelling were observed. Thus, this patient was considered to have giant monostoticOFD of the ilium. The tumor-related area was removed completely by surgery, and the remaining cavity was filled by artificial bones from the opposite ilium. According to the results of follow-up, the patient had normal fexion and extension activities of the right hip joint, and there was no evidence of recurrence of the *** Suture of iliopsoas and gluteus medius muscle following focus curettage and bone grafting is a promising and effective method to treat giant OFD of the ilium. It is a feasible way to fll a large cavity after removing a lesion like the one is this case.

The dynamic density functional theory is applied to study the diffusion of nanoparticles in polymer solutions, in which different diffusion modes have been identified by exploiting the density and free energy evolutions. Under the condition of low polymer concentration, diffusion is controlled by particle free motion with a normal Gaussian type. As the concentration increases, the non- Gaussian behavior can be observed when the particle size is comparable to the correlation length of polymer chain. Particles need to penetrate through a cage and overcome an entropic barrier, where the hopping and the model-coupling diffusion coexist. Further increase of polymer concentration can result in complete restriction of the particle by surrounding polymer segments. In this case, the non-Gaussian process fades away, and particle diffusion is controlled by Rouse dynamics of polymer chains with the generalized Gaussian characteristics.
