Traditional Chinese medicine with its effectiveness should also have stemmed out from such logic system. This article aims to rearticulate the underlying lucid multi-dimensional logic system, which faded in obscurity only because of time-out loss of the mid-right concept. Retracing this past tacit but important concept could uncover a multi-dimensional system over a point relating to all matters while capturing the central core of the matter. The seemingly unmanageable multidimensional logic was strengthened by verification processes which affirmed its further extensions, and made up the language of the people, the concepts of yin-yang(阴阳), and the development of extensions of Ba Gua(八卦) derivatives, which furthered the interpretation of the space-time properties and Chinese medicine.展开更多

文摘To meet the demand for enhanced energy density and improved safety in batteries,anode-free aqueous zinc metal batteries(AF-AZMBs)have garnered significant research interest and attention.Compared with conventional aqueous Zn batteries,AF-AZMBs provide higher theoretical energy density,a more simplified structural design,and improved cost-effectiveness.However,AF-AZMBs are confronted with severe capacity degradation and lifespan reduction due to the absence of an excess zinc inventory.In recent years,extensive research efforts have been devoted to addressing these challenges,resulting in significant advancements.Therefore,there is highly warranted for a comprehensive discussion on AF-AZMBs.Herein,this review provides a thorough analysis and in-depth investigation of recent developments in AF-AZMBs from the perspectives of current collectors,electrolytes,and cathodes.Specifically,the working mechanisms and advantageous features of AF-AZMBs are summarized.The major scientific issues affecting capacity degradation and lifespan reduction are discussed,including inhomogeneous Zn deposition/stripping kinetics,unstable SEI layer,and irreversible cathode material loss.Furthermore,the corresponding strategies to address these issues are highlighted,such as anodic current collector design,electrolyte engineering,and cathodic modification.Finally,several promising directions are explored for the future advancement of AF-AZMBs,including developing high-performance Zn-rich cathodes,regulating solid-state electrolytes,and designing dual-electrode-free zinc-metal batteries.Additionally,exploring advanced characterization and analysis techniques and optimizing pouch cells under practical operating conditions are also mentioned,highlighting the urgent need for further research to address existing bottlenecks.
文摘Laparoscopic and endoscopic cooperative surgery(LECS)is a hybrid minimally invasive technique originally developed for treatment of gastric submucosal tumors.Several modifications of LECS—including inverted LECS,non-exposed endoscopic wall-inversion surgery,and closed LECS have evolved over a period of time to address the earlier concerns about peritoneal contamination and tumor seeding.These innovations have led to the application of combined laparoendoscopic techniques to several gastrointestinal(GI)lesions such as the duodenum,colon,and rectum.This minireview explores the evolution,current applications,and future potential of laparoendoscopic surgery in GI diseases.

文摘To break the limitations of the multi-dimensional(M-D)vibration isolation(VI)platforms with the Stewart-Gough design,such as strongly coupling motions,excessive friction in connections,heavy weight,and limited workspace,this study processes a novel platform integrated by a stiffness-adjustable origami spring sub-structure and a parallel mechanism.The origami-based stiffness-adjustable spring realizes low-frequency VI,and the parallel mechanism symmetry design realizes motions decoupling.In the origami-based sub-leg,the parallel-stack-assembly(PSA)design mechanism with two Miura origami configurations is proposed to generate a symmetrical negative stiffness property.Paired with a linear positive stiffness spring,the origami-based sub-leg has wide-amplitude-high-static-low-dynamic stiffness(WA-HSLDS)characteristics in one direction.Then,with construction of the parallel mechanism connected with origami-based sub-legs,an M-D VI platform is achieved,whose motions in the vertical direction and yaw direction are decoupled with the motions in the other directions.Based on the dynamic model and incremental harmonic balance(IHB)with the arc-length continuation method,appropriate structural parameters in the parallel mechanism part are figured out,and the accurate transmissibility in different directions is defined,which gives the parametric influencing investigations for realization of low-frequency VI performances.Finally,experiments are conducted to validate the accuracy and feasibility of the theoretical methods,and to demonstrate the performance of M-D low-frequency isolation with load-carrying capacity of the proposed VI platform.The integration of the origami into the parallel mechanism results in a compact,efficient,and flexible platform with nonlinear adjustability,offering new possibilities for lightweight M-D VI,and developing the practical applications in high-precision platforms in ocean and aerospace environments.

文摘Allogeneic hematopoietic cell transplantation(allo-HCT) remains a cornerstone therapy for severe hematologic malignancies, offering a potential cure when conventional therapies are ineffective. However, not all patients are suitable recipients of allo-HCT, particularly the elderly patients and those with high comorbidity burdens.Furthermore, patients who develop relapse or graft failure after initial transplantation encounter additional challenges when evaluated for a second transplant.

文摘The development of network and information technology has brought changes to the information environment.The sources of information are becoming more diverse,and intelligence acquisition will be more complicated.The intelligence reflected by different dimensions of scientific and technologi-cal(S&T)data will have their own focuses.It has become inevitable to carry out the multi-dimen-sional research of S&T frontier,which is also a current research hotspot.This paper uses quantita-tive and qualitative research methods to conduct research and analysis of S&T frontier detection from three dimensions including S&T research projects,S&T papers and patents,and proposes related re-search methods and development tools.This work analyzes the S&T frontiers in the field of artificial intelligence and draws conclusions based on the analysis results of real and effective S&T data in three dimensions.
