Physical Review Letters, 2020 In a bearing state, touching spheres (disks in two dimensions) roll on each other without slip. Here we frustrate a system of touching spheres by imposing two different bearing states on opposite sides and search for the configurations of lowest energy dissipation. If the dissipation between contacts of spheres is viscous (with random damping constants)

Dynamic Performance Analysis of Cage in Four-Point Contact Ball Bearing
Lubricants, 2022 Due to the special structure of double-half inner rings, four-point contact ball bearings are prone to uneven forces in the inner raceway during movement, which affects the dynamic performance of the rolling element and cage, and even leads to cage ...

Dr Bear and the adventure Bears [PDF]
Children's Geographies, 2018 “Hello, I see you have a bear on your stand. Why is that?” I ask the man behind the table which is loaded with academic journals, books and promotional literature for delegates at the RGS-IBG 2017 conference to browse through. He smiles and replies, “That’s Barnaby. He’s my bear.” He picks up the bear to give it a cuddle.
