Ascending price auctions typically involve a single price path with buyers paying their final bid price. Using this traditional definition, no ascending price auction can achieve the Vickrey-Clarke-Groves (VCG) outcome for general private valuations in the combinatorial auction setting. We relax this definition by allowing discounts to buyers from the final price of the auction (or alternativel...

As superintendent of the Provincial Lunatic Asylum in Toronto from 1853 to 1875, Dr. Joseph Workman came in contact with most of the medical practitioners in Ontario. One of these was Dr. John Galbraith Hyde of Stratford, a fellow Ulsterman with whom Workman appears to have corresponded regularly. Hyde emigrated to Canada from County Tyrone, Ireland, in 1841, having received his license to prac...

We present the design and implementation of bounded-length sequence (BLS) variables for a CP solver. The domain of a BLS variable is represented as the combination of a set of candidate lengths and a sequence of sets of candidate characters. We show how this representation, together with requirements imposed by propagators, affects the implementation of BLS variables for a copying CP solver, mo...

We construct minimal blocking sets with respect to generators on the Hermitian surfaces H(n, q) when n and q are both odd. A blocking set arises from q + 1 quadrics in PG(n, q) whose polarities commute with a unitary polarity, constructed from the union of Baer sub-quadrics with the common intersections deleted.

2. In practice, researchers find it useful that GMM estimators can be constructed without specifying the full data generating process (which would be required to write down the maximum likelihood estimator.) This has been the case in the study of single equations in a simultaneous system, in the study of potentially misspecified dynamic models designed to match target moments, and in the constr...

Suppose λ is a singular cardinal of uncountable cofinality κ. For a model M of cardinality λ, let No(M) denote the number of isomorphism types of models N of cardinality λ which are L∞λ-equivalent to M. In [She85] Shelah considered inverse κ-systems A of abelian groups and their certain kind of quotient limits Gr(A)/Fact(A). In particular Shelah proved in [She85, Fact 3.10] that for every cardi...

This paper applies a matrix-analytic approach to analyze both the long-term and the short-term loss behaviors of a queue with space priority scheme. Five related performance measures are derived from conditional statistics, including the long-term highpriority and low-priority packet loss probabilities, and the three short-term measures — the average length of a critical period, the average len...
