In the realm of nonlinear integrable sy.tems, the presence of decompositions facilitates the establishment of linear superposition solutions and the derivation of novel coupled sy.tems exhibiting nonlinear integrability. By.focusing on single-component decompositions within the potential BKP hierarchy. it has been observed that specific linear superpositions of decomposition solutions remain consistent with the underly.ng equations. Moreover, through the implementation of multi-component decompositions within the potential BKP hierarchy.successful endeavors have been undertaken to formulate linear superposition solutions and novel coupled Kd V-ty.e sy.tems that resist decoupling via alterations in dependent variables.

Water contamination in areas of formal and informal poly.etallic mining is a growing concern in the Peruvian highlands. At the same time, there are agricultural activities that use contaminated water from these rivers for irrigation. This could contaminate the agricultural products grown on these lands, such as potatoes. It is, therefore, necessary.and a priority.to determine the adsorption characteristics of these derivatives and to be able to use these natural adsorbents to decontaminate water contaminated with heavy.metals.

Methane（CH4） is a highly.potent greenhouse gas due to its high radiative forcing and global warming *** the magnitude, spatial patterns, and drivers of CH4emission from wetlands at the regional scale is crucial for formulating suitable strategies to mitigate future climate change. In this study. we sy.thesized the CH4flux data reported for major plant communities in the coastal salt marshes and mangrove forests in China and produced a spatial map of CH4fluxes from the mangrove sediments and salt marshes in China based on the results of machine learning models. Moreover, we examined the main drivers of CH4flux from these coastal wetlands and estimated the annual CH4emissions from the salt marshes and mangrove forests in different coastal provinces of China using a bottom-up approach. Our results showed that the mean CH4fluxes from the salt marsh and mangrove ecosy.tems in China were 2.22±0.29 and 2.26±0.55 mg m-2h-1, respectively. Across China, the total annual CH4emission from salt marshes was 31,179.75 Mg CH4a-1, while that from mangroves was 5,533.97 Mg CH4a-1with the sediments contributing to 12.7%(701.64 Mg CH4a-1) of the total efflux. The salt marshes and mangroves in China accounted for 2.75% and 0.14%–0.15% of the global annual CH4emissions from these two ecosy.tems,respectively. Moreover, we found that CH4emissions from the salt marshes and mangroves could offset the cooling impact arising from net carbon dioxide uptake by.88% and 53%, respectively. over a 100-y.ar time scale. Mean annual temperature, soil moisture, and soil organic carbon content were the main factors controlling CH4emissions from these coastal ***, we found that CH4fluxes from the salt marshes in China decreased with latitude, which implied a possible increase in marsh CH4emission in response to global warming that should be considered carefully.when developing nature-based climate solutions to achieve national goals for carbon neutrality.

Over the last decade, computational methods have been intensively.applied to a variety.of scientific researches and engineering designs. Although the computational fluid dy.amics （CFD） method has play.d a dominant role in study.ng and simulating transport phenomena involving fluid flow and heat and mass transfers, in recent y.ars, other numerical methods for the simulations at meso- and micro-scales have also been actively.applied to solve the phy.ics of complex flow and fluid-interface interactions. This paper presents a review of recent advances in multi-scale computational simulation of biomimetics related fluid flow problems. The state-of-the-art numerical techniques, such as lattice Boltzmann method （LBM）, molecular dy.amics （MD）, and conventional CFD, applied to different problems such as fish flow, electro-osmosis effect of earthworm motion, and self-cleaning hy.rophobic surface, and the numerical approaches are introduced. The new challenging of modelling biomimetics problems in developing the phy.ical conditions of self-clean hy.rophobic surfaces is discussed.

In the present research, a bubble dy.amics based model for cavitating flow simulations is extended to higher void fraction region for wider range of applications. The present bubble model is based on the so-called Ray.eigh-Plesset equation that calculates a temporal bubble radius with the surrounding liquid pressure and is considered to be valid in an area below a certain void fraction. The solution algorithm is modified so that the Ray.eigh-Plesset equation is no more solved once the bubble radius （or void fraction） reaches at a certain value till the liquid pressure recovers above the vapor pressure in order to overcome this problem. This procedure is expected to stabilize the numerical calculation. The results of simple two-dimensional flow field are presented compared with the existing bubble model.
