Like other helminths, Trichinella spiralis has evolved strategies to allow it to survive in the host organism, including the expression of epitopes similar to those present in either expressed or hidden host antigens. To identify T. spiralis-derived antigens that are evolutionarily conserved in the parasite and its host and that could be responsible for its evasion of the host immune response, ...

In imperfectly discriminating contests with symmetric valuations, equilibrium payoffs are positive shares of the value of the prize. In contrast to a bargaining situation, players’ shares sum to less than one because a residual share of the value is lost due to rent dissipation. In this paper, we consider contests with two players and investigate the relationship between these equilibrium share...

One of the problems pertinent with many visual cryptography (VC) schemes is that of authentication. VC provides a way of sharing secrets between a number of participants. The secrets are in the form of an image that is encoded into multiple pieces known as shares. When these shares are physically superimposed, the secret can be instantly observed. A known problem is that of authentication. How ...

lishment Dynamics program indicates that there is a great deal of churning in the labor market. In fact, in the second quarter of 2005, gross job gains represented 7.2 percent of private employment while gross job losses represented . percent.1 Hardly surprising, there is a lot of interest among economists and politicians in the kinds of jobs that are being created and destroyed. Data from the ...

4 This study considers the influence of the knowledge of existing mode shares on travelers 5 mode choice. This contrasts with traditional mode choice models, where the main objective 6 is to predict the overall mode shares as the aggregate of individual mode choices according 7 to variables encompassing attributes of the modes, and characteristics of the travelers. In this 8 study, a computer-a...

The 1988 physicians' practice costs and income survey (PPCIS) collected detailed costs, revenues, and incomes data for a sample of 3,086 physicians. These data are utilized to update the Health Care Financing Administration (HCFA) cost shares used in calculating the medicare economic index (MEI) and the geographic practice cost index (GPCI). Cost shares were calculated for the national sample, ...

We investigate the problem of fairly allocating indivisible goods among interested agents using the concept of maximin share. Procaccia and Wang showed that while an allocation that gives every agent at least her maximin share does not necessarily exist, one that gives every agent at least 2/3 of her share always does. In this paper, we consider the more general setting where we allocate the go...

The distribution of market shares within an industry is a relevant performance measure for managers and policy makers, allowing the determination of whether a given industry is competitive or not. Usually, the perfect competition model is the reference to judge the efficiency of markets. However, there are empirical studies that show that one of the most evident features of global firms is that...

The ( ) , t n threshold secret sharing scheme proposed by Shamir (1979) encodes the secret key into n shares and those shares are distributed among the participants. Each share incorporates an x-value uniquely designated for every single participant. If the shares are distributed on insecure (or public) channels, malicious users may acquire a few (or all) shares. If the number of shares obtaine...

We study the problem of converting a product of Greenberger-HorneZeilinger (GHZ) states shared by subsets of several parties in an arbitrary way into GHZ states shared by every party. Our result is that if SLOCC transformations are allowed, then the best asymptotic rate is the minimum of bipartite log-ranks of the initial state. This generalizes a result by Strassen on the asymptotic subrank of...
