Asymmetric gear rectifies random robot motion
We experimentally study the dynamics of centimetric robots and their interactions with rotary gears through inelastic collisions. Under the impacts of self-propelled robots, a gear with symmetric teeth diffuses with no preferred direction of motion.

Ocean Governance and Marine Conservation: Institutional Work as a Lever for Ocean Sustainability
ABSTRACT Ocean governance presents one of the most complex environmental policy challenges of our time, requiring coordinated action across multiple scales, sectors and stakeholder groups. This paper applies institutional work theory to systematically examine how actors create, maintain and disrupt the governance arrangements underpinning ocean ...

Kinematic analysis of complex gear mechanisms [PDF]
This paper presents a general kinematic analysis method for complex gear mechanisms. This approach involves the null-space of the adjacency matrix associated with the graph of the mechanism weighted by complex coecients.

Design of Asymmetric Double Circular Arc Gear for Large-Scale High-Pressure Gear Pumps
In this paper, an asymmetric double circular arc gear which is suitable for large-scale high-pressure gear pumps is introduced. While demonstrated its superiority, the displacement formula of the double circular arc gear pump is derived and the gear ...

Stereoselective Construction of Benzo‐Fused Tetrahydropyrrole Thiazines From Saccharin
Saccharin was used as a template to construct a series of 10a‐substituted, benzo‐fused, pyrrolo thiazinone dioxides. Thereafter, diastereo‐divergent 10‐keto reduction gave either diastereomeric alcohol in a process that did not rely on the substituent at 10a's identity.

Triboelectric nanogenerators for vehicle intelligent cockpits
Converting mechanical stimuli from drivers and vehicle motion into electrical signals, triboelectric nanogenerators provide promising interfaces toward passive, flexible, distributed and intelligent sensing for next‐generation automotive cockpits to support three core functional dimensions: driver state monitoring, vehicle state monitoring, and human ...
