Employing the nonlinear local Lyapunov exponent (NLLE) technique, this study assesses the quantitative predictability limit of oceanic mesoscale eddy (OME) tracks utilizing three eddy datasets for both annual and seasonal means. Our findings reveal a discernible predictability limit of approximately 39 days for cyclonic eddies (CEs) and 44 days for anticyclonic eddies (AEs) within the South China Sea (SCS). The predictability limit is related to the OME properties and seasons. The long-lived, large-amplitude, and large-radius OMEs tend to have a higher predictability limit. The predictability limit of AE (CE) tracks is highest in autumn (winter) with 52 (53) days and lowest in spring (summer) with 40 (30) days. The spatial distribution of the predictability limit of OME tracks also has seasonal variations, further finding that the area of higher predictability limits often overlaps with periodic OMEs. Additionally, the predictability limit of periodic OME tracks is about 49 days for both CEs and AEs, which is 5-10 days higher than the mean values. Usually, in the SCS, OMEs characterized by high predictability limit values exhibit more extended and smoother trajectories and often move along the northern slope of the SCS.

Periodontitis is indeed a chronic inflammatory disease caused by microorganisms, and it is a leading cause of tooth loss in adults worldwide [1–3]. The immune system typically maintains a balance with pathogenic bacteria in the body, and the local mucosal immune system effectively monitors and controls these microorganisms to prevent excessive inflammation. However, prolonged exposure to pathogens,release of inflammatory factors, and cellular damage can lead to overactivation of the immune system, resulting in the destruction of supporting structures of the teeth, such as the gingiva, tooth attachment, and alveolar bone resorption, ultimately leading to tooth loss [4–6].

To address the low conductivity and easy agglomeration of transition metal sulfide nanoparticles,FeCoS_(4) nanoparticles embedded in S-doped hollow carbon(FeCoS_(4)@S-HC)composites were successfully fabricated through a combination of hydrothermal processes and sulfidation *** unique bowlshaped FeCoS_(4)/S-HC composites exhibit excellent structural stability with a high specific surface area of 303.7 m^(2)·g^(-1) and a pore volume of 0.93 cm^(3)·g^(-1).When applied as anode material for lithium-ion batteries,the FeCoS_(4)@S-HC anode exhibits efficient lithium storage with high reversible specific capacity(970.2 mA·h·g^(-1) at 100 mA·g^(-1))and enhanced cycling stability(574 mA·h·g^(-1) at 0.2 A·g^(-1) after 350 cycles,a capacity retention of 84%).The excellent lithium storage is attributed to the fact that the bimetallic FeCoS_(4) nanoparticles with abundant active sites can accelerate the electrochemical reaction kinetics,and the bowl-shaped S-HC structure can provide a stable mechanical structure to suppress volume expansion.

作为一种保护性设备，自动切断阀的主要作用是防止在运输或储存过程中有害物质因泄漏而失去控制。当流体通过自动切断阀的流速超过正常的预定范围时（如下游发生泄漏或阀门、管件等出现问题），该阀门就应该关闭，将泄漏控制住，直到发生泄漏的部位被堵住或被隔离。但很多事例表明，由于使用不当，有些自动切断阀并未起到其应有的作用。因此，在预防储罐或管线中的化学物质意外泄漏时，
