Global Policy, EarlyView.ABSTRACT What factors shape African agency in global multilateral reform processes? Rather than a supposed pawn of geopolitical competition, Africa's proactive diplomacy for multilateral reforms is garnering increasing interest. Yet we know surprisingly little about variation in the pursuit of African agency by the African Union (AU) and African Groups

Tooth Profile Design of Tri-arc Harmonic Gear Drive
Jixie chuandong, 2019 Based on the exact conjugate method of harmonic gear drive， the tooth profile design method of the tri-arc harmonic gear drive is proposed and the influence of flex spline profile parameters on the conjugate interval are studied.

neonSoilFlux: An R package for continuous sensor‐based estimation of soil CO2 fluxes
Methods in Ecology and Evolution, EarlyView.Abstract Accurate quantification of soil carbon fluxes is essential to reduce uncertainty in estimates of the terrestrial carbon sink. However, these fluxes vary over time and across ecosystem types and so, it can be difficult to estimate them accurately across large scales.

Disciplining the “Queen of the World”? Responsible Innovation as a Way of Life
Business Ethics, the Environment &Responsibility, EarlyView.ABSTRACT This paper offers a critical reflection on the concept of responsible innovation as defined during the last decades. We argue that the emphasis on innovation as a process risks neglecting the very goals of innovation, namely societal desirability and acceptability. Thus, we suggest reconsidering the role of imagination, the “Queen of the world”

Study on Status and Problem Research of Harmonic Gear Drive
Jixie chuandong, 2020 The development and application of harmonic gear drive in recent years are briefly reviewed，the development of gear tooth profile and the main factors affecting the life of reducer are mainly expounded. In the traditional tooth profile，the tooth profile has undergone the development stage from the linear tooth profile to the arc tooth profile，and then ...

Computing Skinning Weights via Convex Duality
Computer Graphics Forum, EarlyView.We present an alternate optimization method to compute bounded biharmonic skinning weights. Our method relies on a dual formulation, which can be optimized with a nonnegative linear least squares setup. Abstract We study the problem of optimising for skinning weights through the lens of convex duality.

Non‐Rigid 3D Shape Correspondences: From Foundations to Open Challenges and Opportunities
Computer Graphics Forum, EarlyView.Abstract Estimating correspondences between deformed shape instances is a long‐standing problem in computer graphics; numerous applications, from texture transfer to statistical modelling, rely on recovering an accurate correspondence map. Many methods have thus been proposed to tackle this challenging problem from varying perspectives, depending on ...
