Trade and Embodied CO Emissions: Analysis from a Global Input-Output Perspective.

Global trade drives the world's economic development, while a large amount of embodied carbon is transferred among different countries and regions. Based on a multi-regional input-output model, the trade embodied carbon transfers of bilateral trade between 185 countries/regions around the world were calculated. On the basis, regional trade embodied carbon transfer patterns and major national trade patterns in six continents, eight major economic cooperation organizations, and six representative countries/regions were further analyzed.

Spatial correlation network characteristics of embodied carbon transfer in global agricultural trade.

Agricultural carbon emission is an important cause of climate change, and the carbon transfer caused by agricultural trade is a key area related to carbon emissions of all countries. Based on the Eora database, this paper aims to constructs a multi-region input-output database of 185 countries or regions, analyzes a spatial correlation network of embodied net carbon transfer in global agricultural trade by using UCINET, selects multi-dimensional network measurement indicators, and comprehensively studies the global evolution characteristics and functional features of network plate role of embodied carbon transfer in the global agricultural trade. The result shows that the embodied net carbon transfer network of global agricultural trade is densely connected, the spatial correlation spillover effect is significant, and the edge of the network core structure is clear.

Design and validation of a foot-ankle dynamic simulator with a 6-degree-of-freedom parallel mechanism.

An in vitro simulation test using a designed well-targeted test rig has been regarded as an effective way to understand the kinematics and dynamics of the foot and ankle complex in the dynamic stance phase, and it also allows alterations in both internal and external control compared to in vivo tests. However, current simulators are limited by some assumptions. In this study, a novel foot and ankle bionic dynamic simulator was developed and validated.

[A Multi-segment Foot Model for Gait Simulation Based on Automatic Dynamic Analysis of Mechanical Systems].

This study aims to establish a multi-segment foot model which can be applied in dynamic gait simulation.The effectiveness and practicability of this model were verified afterwards by comparing simulation results with those of previous researches.Based on a novel hybrid dynamic gait simulator,bone models were imported into automatic dynamic analysis of mechanical systems(ADAMS).
