文摘With the gradual advancement of research methods and technologies,various biological processes have been identified as playing roles in the pathogenesis of neurodegenerative diseases.However,current descriptions of these biological processes do not fully explain the onset,progression,and development of these conditions.Therefore,exploration of the pathogenesis of neurodegenerative diseases remains a valuable area of research.This review summarizes the potential common pathogeneses of Alzheimer’s disease,Parkinson’s disease,amyotrophic lateral sclerosis,Huntington’s disease,frontotemporal lobar dementia,and Lewy body disease.Research findings have indicated that several common biological processes,including aging,genetic factors,progressive neuronal dysfunction,neuronal death and apoptosis,protein misfolding and aggregation,neuroinflammation,mitochondrial dysfunction,axonal transport defects,and gut microbiota dysbiosis,are involved in the pathogenesis of these six neurodegenerative diseases.Based on current information derived from diverse areas of research,these biological processes may form complex pathogenic networks that lead to distinctive types of neuronal death in neurodegenerative diseases.Furthermore,promoting the regeneration of damaged neurons may be achievable through the repair of affected neural cells if the underlying pathogenesis can be prevented or reversed.Hence,these potential common biological processes may represent only very small,limited elements within numerous intricate pathogenic networks associated with neurodegenerative diseases.In clinical treatment,interfering with any single biological process has proven insufficient to completely halt the progression of neurodegenerative diseases.Therefore,future research on the pathogenesis of neurodegenerative diseases should focus on uncovering the complex pathogenic networks,rather than isolating individual biological processes.Based on this,therapies that aim to block or reverse various targets involved in the potential pathogenic mechanisms of neurodegenerative diseases may be promising directions,as current treatment methods that focus on halting a single pathogenic factor have not achieved satisfactory efficacy.

文摘The available heat content (stored heat energy) of hot dry rock (HDR) at a depth of 1–10 km in the global land crust is estimated to be 5.06×10~8 EJ,attracting considerable global attention.This paper presents a comprehensive analysis of the geological framework,HDR resource potential,exploration advancements,and the development of enhanced geothermal systems (EGSs) in China.HDR resources are extensively distributed across China.Within the depth range of 3–10 km,China’s estimated potential approximates2.29×10~7 EJ,with a theoretical power generation capacity of approximately 1.67×10^(16) k Wh.Replacing coal power with HDR can help to achieve a net emission reduction of 1.34×10^(16) kg CO_(2) (approximately1.34×10^(13) t),representing an emission reduction efficiency of 94.4%.Based on a development cycle of100 years,the average annual emission reduction reaches 1.34×10^(10) t CO_(2),equivalent to 117%of China’s annual carbon emissions in 2022.Furthermore,in the context of global warming,the development and utilization of HDR,which is feasible in virtually any region worldwide,offers significant potential to support global carbon reduction efforts.China has made substantial progress in HDR exploration in recent years.This paper systematically classifies China’s HDR resources into four genetic types—highly radioactive heat-producing,sedimentary basin,active volcanic,and intensely tectonic zones—and offers detailed exploration insights for each category.Each classification exhibits distinct geological and tectonic characteristics that influence heat source mechanisms and resource distribution.Furthermore,this paper documents significant advances in EGS construction,particularly in the Gonghe Basin on the northeastern margin of the Qianghai-Xizang Plateau and the Matouying uplift in the North China Basin,where successful reservoir stimulation,microseismic monitoring,and experimental power generation have been achieved.Despite these developments,challenges persist,including technical adaptability under complex geological conditions and the economic viability of large-scale HDR development.This paper suggests that future initiatives should emphasize resource exploration,technological research,and policy support to foster sustainable HDR resource development in China,thereby contributing to the global energy transition and environmental sustainability.

文摘The microstructural evolution of a cold-rolled and intercritical annealed medium-Mn steel(Fe-0.10C-5Mn)was investigated during uniaxial tensile testing.In-situ observations under scanning electron microscopy,transmission electron microscopy,and X-ray diffraction analysis were conducted to characterize the progressive transformation-induced plasticity process and associated fracture initiation mechanisms.These findings were discussed with the local strain measurements via digital image correlation.The results indicated that Lüders band formation in the steel was limited to 1.5%strain,which was mainly due to the early-stage martensitic phase transformation of a very small amount of the less stable large-sized retained austenite(RA),which led to localized stress concentrations and strain hardening and further retardation of yielding.The small-sized RA exhibited high stability and progressively transformed into martensite and contributed to a stably extended Portevin-Le Chatelier effect.The volume fraction of RA gradually decreased from 26.8%to 8.2%prior to fracture.In the late deformation stage,fracture initiation primarily occurred at the austenite/martensite and ferrite/martensite interfaces and the ferrite phase.
