Fifty years ago, Vickrey published his famous mechanism for auctioning a single good in limited supply. The main property of Vickrey's mechanism is efficiency in dominant strategies. In absence of collusion, this is a ...
ARBAC Policy for a Large Multi-National Bank
(2011-04-27)
Administrative role-based access control (ARBAC) is the first comprehensive administrative model proposed for role-based access control (RBAC). ARBAC has several features for designing highly expressive policies, but current ...
Partial Reversal Acyclicity
(2011-04-14)
Partial Reversal (PR) is a link reversal algorithm which ensures that the underlying graph structure is destination-oriented and acyclic. These properties of PR make it useful in routing protocols and algorithms for solving ...
Mechanism Design with Approximate Valuations
(2011-02-16)
In mechanism design, we replace the strong assumption that each player knows his own payoff type EXACTLY with the more realistic assumption that he knows it only APPROXIMATELY. Specifically, we study the classical problem ...
Efficient Marginal Likelihood Optimization in Blind Deconvolution
(2011-04-04)
In blind deconvolution one aims to estimate from an input blurred image y a sharp image x and an unknown blur kernel k. Recent research shows that a key to success is to consider the overall shape of the posterior distribution ...
Severe depression is associated with increased microglial quinolinic acid in subregions of the anterior cingulate gyrus: Evidence for an immune-modulated glutamatergic neurotransmission?
(2011-08-10)
Abstract Background Immune dysfunction, including monocytosis and increased blood levels of interleukin-1, interleukin-6 and tumour necrosis factor α has been observed during acute episodes of major depression. These ...
