The nuclear mean-field potential built up during the ^(12)C+^(12)C and ^(16)O+^(16)O collisions at low energies relevant for the carbon-and oxygen-burning processes is constructed within the double-folding model(DFM) using the realistic ground-state densities of^(12)C and^(16)O, and CDM3Yn density-dependent nucleon–nucleon(NN) interaction. The rearrangement term, indicated by the Hugenholtz–van Hove theorem for the single-particle energy in nuclear matter, is properly considered in the DFM calculation. To validate the use of the density-dependent NN interaction at low energies, an adiabatic approximation was suggested for the dinuclear overlap density. The reliability of the nucleus–nucleus potential predicted through this low-energy version of the DFM was tested in the optical model(OM) analysis of the elastic^(12)C+^(12)C and ^(16)O+^(16)O scattering data at energies below 10 MeV/*** OM results provide a consistently good description of the elastic angular distributions and 90 excitation function. The dinuclear mean-field potential predicted by the DFM is further used to determine the astrophysical S factor of the ^(12)C+^(12)C and ^(16)O+^(16)O fusions in the barrier penetration model. Without any adjustment of the potential strength, our results reproduce the non-resonant behavior of the S factor of the ^(12)C+^(12)C and ^(16)O+^(16)O fusions very well over a wide range of energies.

驾驶员的停车场选择行为受到诸多因素的影响,这些因素将驾驶员的行为和车辆类型区分开来。在许多发展中国家,城市交通以摩托车为主,这种交通工具的多样性造成了许多交通问题,包括车辆所有权,交通拥堵,交通事故或者与之相关的停车问题（如停车位不足,非法停车等）。本研究阐明了停车场选择模型的影响因素,该模型不仅考虑汽车驾驶员,还考虑了摩托车驾驶员。本研究采用随机效用最大化（RUM）假设下的各种离散选择模型,对影响驾驶员停车选择行为模型的因素进行了评估。结果表明,混合logit模型对胡志明市摩托车和汽车驾驶员数据的处理效果较好。停车费用、停车场到目的地步行距离、停车场容量和排队时间对摩托车用户和汽车用户的停车选择均有显著影响。导航和路牌变量对汽车用户的停车选择有显著影响,但对摩托车用户的停车选择影响较小。本研究结果旨在为发展中国家和摩托车为主要交通方式城市的城市交通规划、停车需求预测和管理提供帮助。同时,研究结果有助于提高停车服务质量,减少停车问题对交通的影响,为未来技术解决方案的实施奠定基础。

We report a panel of severe inflammatory and vascular intraocular disorders occurring during interferon-alpha (IFN-α) treatment in eight hepatitis C virus (HCV)-infected patients. These events include three cases of Vogt-Koyanagi-Harada like (VKH) disease (an association of panuveitis, retinal detachment, ear and meningeal detachment and skin and hair changes), two cases of central retinal vein occlusion, one case of central retinal artery occlusion, one case of severe hypertensive retinopathy and one case of bilateral ischemic optic neuropathy with severe visual impairment. Rare as they are, such severe ophthalmological complications require a close follow-up of HCV-infected patients under IFN-α treatment with ophthalmological monitoring if any ocular manifestation occurs.
