Schwann cell transplantation is considered one of the most promising cell-based therapy to repair injured spinal cord due to its unique growth-promoting and myelin-forming properties.A the Food and Drug Administration-approved Phase I clinical trial has been conducted to evaluate the safety of transplanted human autologous Schwann cells to treat patients with spinal cord injury.A major challenge for Schwann cell transplantation is that grafted Schwann cells are confined within the lesion cavity,and they do not migrate into the host environment due to the inhibitory barrier formed by injury-induced glial scar,thus limiting axonal reentry into the host spinal *** we introduce a combinatorial strategy by suppressing the inhibitory extracellular environment with injection of lentivirus-mediated transfection of chondroitinase ABC gene at the rostral and caudal borders of the lesion site and simultaneously leveraging the repair capacity of transplanted Schwann cells in adult rats following a mid-thoracic contusive spinal cord *** report that when the glial scar was degraded by chondroitinase ABC at the rostral and caudal lesion borders,Schwann cells migrated for considerable distances in both rostral and caudal *** Schwann cell migration led to enhanced axonal regrowth,including the serotonergic and dopaminergic axons originating from supraspinal regions,and promoted recovery of locomotor and urinary bladder ***,the Schwann cell survival and axonal regrowth persisted up to 6 months after the injury,even when treatment was delayed for 3 months to mimic chronic spinal cord *** findings collectively show promising evidence for a combinatorial strategy with chondroitinase ABC and Schwann cells in promoting remodeling and recovery of function following spinal cord injury.

Photovoltaic (PV) modules, as essential components of solar power generation systems, significantly influence unitpower generation *** service life of these modules directly affects these costs. Over time, the performanceof PV modules gradually declines due to internal degradation and external environmental *** cumulativedegradation impacts the overall reliability of photovoltaic power generation. This study addresses the complexdegradation process of PV modules by developing a two-stage Wiener process model. This approach accountsfor the distinct phases of degradation resulting from module aging and environmental influences. A powerdegradation model based on the two-stage Wiener process is constructed to describe individual differences inmodule degradation processes. To estimate the model parameters, a combination of the Expectation-Maximization(EM) algorithm and the Bayesian method is employed. Furthermore, the Schwarz Information Criterion (SIC) isutilized to identify critical change points in PV module degradation trajectories. To validate the universality andeffectiveness of the proposed method, a comparative analysis is conducted against other established life predictiontechniques for PV modules.

通过探讨父母控制(心理控制与行为控制)和中学生生活满意度间的关系,检验中学生的孝道信念在二者间的中介作用。通过采用父母心理控制问卷、行为控制问卷、双元孝道量表、生活满意度量表对湖南省三所中学的539名中学生匿名施测。结果显示:父母心理控制对中学生的生活满意度有显著负向预测作用,父母行为控制对中学生的生活满意度具有显著正向预测作用;互惠孝道在父母心理控制与生活满意度间起部分中介作用,互惠孝道与权威孝道在父母行为控制与生活满意度间均起部分中介作用。说明父母控制既直接影响中学生的生活满意度,也可通过中学生的孝道信念间接影响其对生活的满意度。

Hydroformylation could convert olefins and syngas （mixture of H2and CO） into aldehydes with a great atomic *** transformation serves as one of the most prominent processes in modern chemical industry, as it provides over 10million tons of aldehydes as feedstock for our daily essential products such as plasticizers, paints, solvents, and pharmaceuticals. This process generally requires efficient yet robust catalyst to realize decent efficacy. Compared with metals such as Co, Ru, and Pd, rhodium （Rh）-based catalysts stand out due to its superior activity even under mild reaction conditions, and dominate over 70%of global hydroformylation processes.

Degradation and self-recovery of polycrystalline Silicon(poly-Si) Thin film transistor(TFT) by using complementary metal oxide semiconductor(CMOS)inverter were investigated. Under DC stress, degradation mechanisms were clarified by comparing the Voltage transfer characteristics(VTC) of fresh and stressed inverters. It is determined that Negative bias temperature instability(NBTI) of p-TFT dominates the degradation of the inverter under zero bias DC stress. After removing the stress, the VTC continues to be degraded, because the interface trap-states and the grain boundary trapstates increase due to hydrogen species diffusion. It is found out that the VTC is shifted to its right side severely with negative bias stress of VIN. The NBTI of p-TFT is enhanced and the NBTI of n-TFT also plays a role on the degradation. When removing the negative bias stress, the self-recovery of NBTI of nTFT and the continuing degradation of NBTI of p-TFT become competing mechanisms, together controlling the VTC after-stress behavior. Consequently, the continuing degradation of NBTI of p-TFT is restrained by selfrecovery of NBTI of n-TFT.
