在抽象危险犯立法日益增多的刑法活性化时代,研究抽象危险犯能否反证具有重要意义。抽象危险犯是结果犯,且实施构成要件行为仅推定产生抽象危险结果。除一般产生危险的情形外,存在例外无危险的情形,此时应当允许反证出罪以合理限制处罚范围。反证既不违反疑罪从无原则,也不会将抽象危险犯异化为具体危险犯。所有抽象危险犯在理论上均允许反证。反证时,应当以行为人人身特性之外的客观情况为素材,在行为时以社会一般人标准考察是否存在抽象危险。此外,“但书”条款并非反证的适用依据。

本工作采用简单高效的一步水热法工艺制备了具有一维有序结构的金红石TiO_(2)纳米线阵列,设计了Au/TiO_(2)/FTO器件结构的金红石TiO_(2)纳米线忆阻器,系统研究了器件的阻变存储特性和存储机制,构建了器件基于氧空位迁移的非线性阻变存储机制模型。结果表明,Au/TiO_(2)/FTO结构金红石TiO_(2)纳米线忆阻器具有非易失性的双极性阻变存储特性,器件的阻变开关比可以稳定地保持在10^(2)以上。此外,器件在低阻态时满足线性的欧姆导电特性,在高阻态时服从陷阱控制的空间电荷限制电流传导机制,而器件的阻变存储行为则遵循基于氧空位迁移的非线性离子迁移阻变存储机制,研究结果表明金红石TiO_(2)纳米线忆阻器在下一代非易失性存储器方面具有重要的应用潜力。

Objective To investigate the effects of acupotomy on skeletal muscle fibrosis and collagen deposition in a rabbit knee osteoarthritis(KOA)*** Rabbits(n=18)were randomly divided into control,KOA,and KOA+acupotomy(Apo)groups(n=6).The rabbits in the KOA and Apo groups were modeled using the modified Videman's method for 6 *** modeling,the Apo group was subjected to acupotomy once a week for 3 weeks on the vastus medialis,vastus lateralis,rectus femoris,biceps femoris,and anserine bursa tendons around the *** behavior of all animals was recorded,rectus femoris tissue was obtained,and histomorphological changes were observed using Masson staining and transmission electron *** expression of transforming growth factor-β1(TGF-β1),Smad 3,Smad 7,fibrillar collagen types I(Col-I)and III(Col-III)was detected using Western blot and real-time polymerase chain reaction(RT-pCR).Results Histological analysis revealed that acupotomy improved the microstructure and reduced the collagen volume fraction of rectus femoris,compared with the KOA group(p=.034).Acupotomy inhibited abnormal collagen deposition by modulating the expression of fibrosis-related proteins and mRNA,thus preventing skeletal muscle *** blot and RT-pCR analysis revealed that in the Apo group,Col-I,and Col-III protein levels were significantly lower than those in the KOA group(both pp=.0031;p=.0046).Compared with the KOA group,the protein levels of TGF-β1 and Smad 3 were significantly reduced(both pp=.0007;p=.0011).Conversely,the levels of protein and mRNA of Smad 7 were significantly higher than that in the KOA group(pp=.0271).Conclusion Acupotomy could alleviate skeletal muscle fibrosis and delay KOA progress by inhibiting collagen deposition through the TGF-β/Smad pathway in the skeletal muscle of KOA rabbits.
