Combined transplantation of GDAs^(BMP) and hr-decorin in spinal cord contusion repair

引用

Neural Regeneration Research 2013年第24期8卷 2236-2248页

作者： liang Wu Jianjun Li liang Chen Hong Zhang Li Yuan Stephen ja Davies School of Rehabilitation Medicine Capital Medical University Department of Neural Functional Reconstruction of Spine and Spinal Cord China Rehabilitation Research Center Rehabilitation Center Beijing Xiaotangshan Rehabilitation Hospital Department of Neurosurgery University of Colorado Denver

Following spinal cord injury, astrocyte proliferation and scar formation are the main factors inhibiting the regeneration and growth of spinal cord axons. Recombinant decorin suppresses inflammatory reactions, inhibits glial scar formation, and promotes axonal growth. Rat models of T8 spinal cord contusion were created with the NYU impactor and these models were subjected to combined transplantation of bone morphogenetic protein-4-induced glial-restricted precursor-derived astro- cytes and human recombinant decorin transplantation. At 28 days after spinal cord contusion, dou- ble-immunofluorescent histochemistry revealed that combined transplantation inhibited the early in- flammatory response in injured rats. Furthermore, brain-derived neurotrophic factor, which was se- creted by transplanted cells, protected injured axons. The combined transplantation promoted ax- onal regeneration and growth of injured motor and sensory neurons by inhibiting astrocyte prolif- eration and glial scar formation, with astrocytes forming a linear arrangement in the contused spinal cord, thus providing axonal regeneration channels.

Optimization Model for Inter-regional Emergency Power Dispatch Considering Transmission Rights Allocation

引用

Dianwang Jishu/Power System Technology 2025年第1期49卷 223-231页

作者： Guan, Jinyu liang, Zhifeng Chang, Li Cao, Rongzhang Li, Lili NARI Group Corporation State Grid Electric Power Research Institute Jiangsu Province Nanjing 211106 China NARI Technology Co. Ltd. Jiangsu Province Nanjing 211106 China Department of Electrical Engineering Tsinghua University Haidian District Beijing 100084 China National Power Dispatch and Control Centre Xicheng District Beijing 100031 China

Inter-regional emergency power dispatch refers to the mandatory fallback guarantee measures for ensuring supply or absorption of emergency demands within provincial grids when market-based approaches have been exhausted from the perspective of mutual assistance in electricity surplus and shortage across provinces and regions. When it is impossible to rely on market declarations directly, how to allocate emergency demands and inter-provincial/regional support capacities and distribute the limited available transfer capacity reasonably among market entities is one of the key issues urgently needing to be addressed in current emergency dispatch. This paper proposes an optimization model for inter-provincial and inter-regional emergency power dispatch considering transmission rights. Inspired by China's current mechanism for allocating transmission channel revenue rights, based on local prioritization and the urgency of emergency demands, a method for determining the priority of emergency transactions considering transmission rights allocation is proposed. This method transforms transmission rights into priority transaction rights, addressing the lack of a reasonable basis for transmission capacity allocation in the emergency dispatch phase. Considering constraints such as available transfer capacity, transaction flow balance, and transaction point power balance constraints, to maximize adjusted social welfare, a clearing model for emergency dispatch optimization considering transaction path priority is constructed. Comparative analysis of the optimization results of three 1e clearing modes, price-based sequential clearing, scenario-based separation, and clearing with transaction path priority, validates the effectiveness and superiority of the proposed optimization clearing model and analyzes the impact of related parameter settings on the clearing results. © 2025 Power System Technology Press.

作者： liang Lizhen LIU Shanhu WU Yong WEI Jianglong XIE Yahong Hefei Institutes of Physical Science Chinese Academy of Sciences School of Science Shandong Jianzhu University School of Electronic and Information Engineering Anhui Jianzhu University

In order to better build the neutral beam injector with negative ion source (NNBI), the pre-research on key technologies has been carried out for the comprehensive research facility for fusion technology (CRFFT). Cesium seeding into negative-ion sources is a prerequisite to obtain the required negative hydrogen ion. The performance of ion source largely depends on the cesium conditions in the source. It is very necessary to quantitatively measure the amount of cesium in the source during the plasma on and off periods (vacuum stage).

Spin-orbit torque （SOT）,as a promising writing method for magnetic random-access memory （MRAM）,has garnered widespread interest for over a decade [1].Heavy metals,such as β-W,have been broadly adopted as spin current sources,but suffer from phase change at a limited thickness,resulting in a dramatic reduction of the charge-tospin conversion efficiency θSH[2].The thickness limitation leads to stringent etching conditions and large distribution among devices,posing challenges for simultaneously satisfying SOT efficiency,etching-stop margins,and back-end-ofline （BEOL） compatibility.
