Mechanisms with Referrals: VCG Mechanisms and Multilevel Mechanisms [PDF]
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

Models and Mechanisms of Stomatal Mechanics
The mechanism of stomatal function (control of gas flux through the plant surface via regulation of pore size) is fundamentally mechanical. The material properties of the pore-forming guard cells must play a key role in setting the dynamics and degree of stomatal opening/closure, but our understanding of the molecular players involved and resultant ...

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
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

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 ...

Pharmacokinetics of Tyrosol Metabolites in Rats
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
