Ratiometric mode with dyads: a breakthrough in dynamic trapping and quantification for redox regulation in living cells

Redox-based post-translational modification of protein thiols has become an attractive strategy in cellular homeostasis and cell signaling.Due to the reductive end of the redox buffer network,the vicinal dithiol-containing proteins(VDPs)maintains an appropriate oxidation-reduction state of proteins through the reversible transformation from vicinal dithiols to disulfide,which is responsible for a variety of

Geochemistry of Clayey Aquitard Pore Water as Archive of Paleo-Environment,Western Bohai Bay

The record of paleo-environment in clayey aquitard pore water is much more effective relative to aquifer groundwater owing to the low permeability of clayey aquitard. Oxygen-18 (18O), deuterium (D), an...     

数学专业师范生教学技能的调查研究--以四川文理学院为例

教学技能是教师最重要的专业素质，是师范生在大学期间需要掌握的基础职业技能。通过调查研究表明，数学专业大学生教学基本功发展不平衡，不同年级学生的教学技能水平存在显著差异。教学实践、课改认知、教学交流、自主练习是影响教学技能的四个主因子。男女生在表达技能、教学设计技能、几何作图技能等方面差异显著，而在教材分析、多媒体使用方面不存在显著性差异。要通过完善教学技能培养机制，夯实师范基础技能培养，改革教学技能培养方式等途径，合力提高师范生的教学技能，增强就业竞争力。     

A generalized super AKNS hierarchy associated with orthosymplectic Lie superalgebra OSP(2,2) and its super bi-Hamiltonian structures

For the orthosymplectic Lie superalgebra $\text{◂⋅▸}OSP(2,2)$, we choose a set of basis matrices. A linear combination of those basis matrices presents a spatial spectral matrix. The compatible condition of the spatial part and the corresponding temporal parts of the spectral problem leads to a generalized super AKNS (GSAKNS) hierarchy. By making use of the supertrace identity, the obtained GSAKNS hierarchy can be written as the super bi-Hamiltonian structures.     

激光快速成型TC4合金显微组织及力学性能

采用金相显微镜、扫描电镜、电子拉伸机等，研究了激光快速成型TC4合金沉积态在平行沉积方向和垂直沉积方向的组织和力学性能.结果表明:激光快速成型TC4合金沉积态宏观组织沿沉积方向生长的粗大β柱状晶呈明暗相间的条带状结构，具备典型的魏氏组织特征;垂直沉积方向的强度比平行沉积方向的强度高，但塑性低;合金断口为韧窝状断口，垂直沉积方向的断口韧窝尺寸比平行沉积方向的小.
