Dynamics of drop impact on solid surfaces: evolution of impact force and self-similar spreading
, 2017 We investigate the dynamics of drop impacts on dry solid surfaces. By synchronising high-speed photography with fast force sensing, we simultaneously measure the temporal evolution of the shape and impact force of impacting drops over a wide range of ...

Biological Reviews, EarlyView.ABSTRACT Tool use research has long made the distinction between tool using that is considered learned and flexible, and that which appears to be instinctive and stereotyped. However, animals with an inherited tool use specialisation can exhibit flexibility, while tool use that is spontaneously innovated can be limited in its expression and facilitated

Effect of the additive concentration on the modification of petroleum coke and anode quality
The Canadian Journal of Chemical Engineering, EarlyView.Abstract Calcined petroleum coke is one of the major raw materials for anode manufacturing, which is used as the carbon source in electrolytic cells for primary aluminium production. It constitutes around 65%–70% of the anode recipe. Therefore, the quality of calcined coke has an important impact on anode quality, which affects the cost, energy ...

A study of joint damping in metal plates
, 2006 For satellite applications the determination of the correct dynamic behaviour and in particular the structural damping is important to assess the vibration environment for the spacecraft subsystems and ultimately their capability to withstand the launch ...

Fault Sneaking Attack: a Stealthy Framework for Misleading Deep Neural Networks
, 2019 Despite the great achievements of deep neural networks (DNNs), the vulnerability of state-of-the-art DNNs raises security concerns of DNNs in many application domains requiring high reliability.We propose the fault sneaking attack on DNNs, where the ...

Cytoskeleton, EarlyView.ABSTRACT Cooperativity between cytoskeletal proteins is crucial for spatiotemporal coordination in biological processes, like oogenesis. In mammalian and Drosophila oogenesis, proper assembly and function of actin networks require coordination between actin assembly factors Spire and formins, as well as actin‐associated proteins like myosins and Rab ...
