Tribological and dry drilling performance of WS2/Cr-AlCrN coatings

open access: yesJournal 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]

open access: yesSSRN 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

Reallocation mechanisms [PDF]

open access: yesProceedings of the fifteenth ACM conference on Economics and computation, 2014
We consider reallocation problems in settings where the initial endowment of each agent consists of a subset of the resources. The private information of the players is their value for every possible subset of the resources. The goal is to redistribute resources among agents to maximize efficiency.

Hexameric and pentameric complexes of the ExbBD energizer in the Ton system

open access: yeseLife, 2018
Gram-negative bacteria import essential nutrients such as iron and vitamin B12 through outer membrane receptors. This process utilizes proton motive force harvested by the Ton system made up of three inner membrane proteins, ExbB, ExbD and TonB. ExbB and

Imprinting Mechanisms [PDF]

open access: yesGenome Research, 1998
A number of recent studies have provided new insights into mechanisms that regulate genomic imprinting in the mammalian genome. Regions of allele-specific differential methylation (DMRs) are present in all imprinted genes examined. Differential methylation is erased in germ cells at an early stage of their development, and germ-line-specific ...

How parametric resonance mechanism follows quench mechanism in disoriented chiral condensate [PDF]

open access: yes, 2001
We show how parametric resonance mechanism follows quench mechanism in the classical linear sigma model. The parametric resonance amplifies long wavelength modes of the pion for more than $10 fm/c$.

Pharmacokinetics of Tyrosol Metabolites in Rats

open access: yesMolecules, 2016
Tyrosol is considered a potential antioxidant; however, little is known regarding the pharmacokinetics of its metabolites. To study the pharmacokinetics of tyrosol-derived metabolites after oral administration of a single dose of tyrosol, we attempted to
