Mechanical Mechanisms of Chromosome Segregation [PDF]
Cells, 2021 Chromosome segregation—the partitioning of genetic material into two daughter cells—is one of the most crucial processes in cell division. In all Eukaryotes, chromosome segregation is driven by the spindle, a microtubule-based, self-organizing subcellular structure.

Tribological and dry drilling performance of WS2/Cr-AlCrN coatings
Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2021 Dry drilling gives a higher request to the anti-friction property of cutting tools. However, most tool coatings commonly have less lubricant effect. In present paper, WS2/Cr layer was deposited on AlCrN layer by a radio frequency magnetron sputtering ...

Mechanisms with Referrals: VCG Mechanisms and Multilevel Mechanisms [PDF]
SSRN Electronic Journal, 2016 We study mechanisms for environments in which only some of the agents are directly connected to a mechanism designer and the other agents can participate in a mechanism only through the connected agents' referrals. Agents' network connections are private information, which can be strategically concealed by avoiding making referrals; while the mechanism
