Diagnosis of CO2 dynamics and fluxes in global coastal oceans

Global coastal oceans as a whole represent an important carbon sink but, due to high spatial–temporal variability, a mechanistic conceptualization of the coastal carbon cycle is still under development, hindering the modelling and inclusion of coastal carbon in Earth System Models. Although temperature is considered an important control of sea surface pCO₂, we show that the latitudinal distribution of global coastal surface pCO₂ does not match that of temperature, and its inter-seasonal changes are substantially regulated by non-thermal factors such as water mass mixing and net primary production. These processes operate in both ocean-dominated and river-dominated margins, with carbon and nutrients sourced from the open ocean and land, respectively. These can be conceptualized by a semi-analytical framework that assesses the consumption of dissolved inorganic carbon relative to nutrients, to determine how a coastal system is a CO₂ source or sink. The framework also finds utility in accounting for additional nutrients in organic forms and testing hypotheses such as using Redfield stoichiometry, and is therefore an essential step toward comprehensively understanding and modelling the role of the coastal ocean in the global carbon cycle.     

A stage-specific cell-manipulation platform for inducing endothelialization on demand

Endothelialization is of great significance for vascular remodeling, as well as for the success of implanted vascular grafts/stents in cardiovascular disease treatment. However, desirable endothelialization on synthetic biomaterials remains greatly challenging owing to extreme difficulty in offering dynamic guidance on endothelial cell (EC) functions resembling the native extracellular matrix-mediated effects. Here, we demonstrate a bilayer platform with near-infrared-triggered transformable topographies, which can alter the geometries and functions of human ECs by tunable topographical cues in a remote-controlled manner, yet cause no damage to the cell viability. The migration and the adhesion/spreading of human ECs are respectively promoted by the temporary anisotropic and permanent isotropic topographies of the platform in turn, which appropriately meet the requirements of stage-specific EC manipulation for endothelialization. In addition to the potential of promoting the development of a new generation of vascular grafts/stents enabling rapid endothelialization, this stage-specific cell-manipulation platform also holds promise in various biomedical fields, since the needs for stepwise control over different cell functions are common in wound healing and various tissue-regeneration processes.     

社会规范、社会监督对农村人居环境整治参与意愿与行为的影响——基于广义连续比模型的实证分析

农户参与农村人居环境整治的意愿与行为是农村环境改善最为直接的动力,也是实现农村生态宜居和生态文明制度改革细则出台的重要依据。为细致探究农户参与农村人居环境整治的意愿与行为,本文基于社会规范和社会监督的视角,利用西藏707户调查数据,运用广义连续比模型,通过对样本数据分组,综合分析了农户人居环境整治参与意愿、行为及意愿与行为一致性的影响因素。结果显示：①农户具有参与农村人居环境整治意愿的占比略超过一半（51.77%）,但参与意愿与行为一致性较差;②邻居参与积极性、保洁员监督、村庄人居环境改善能减少疾病传播等因素对农户参与意愿与行为均产生显著的积极影响;③农户的文化程度、村民监督及政府宣传有利于农户参与意愿向参与行为转化。本文的研究结论支持了农村人居环境整治中政府主导、农户参与的整治模式,对推进农村人居环境整治具有一定的政策启示,同时对政府出台农村环境管理政策亦有一定的借鉴意义。
