BACKGROUND AND AIMS A recent review of economic studies relating to gastric cancer revealed that authors use different tests to estimate utilities in patients with and without gastric cancer. Our aim was to determine the utilities of gastric premalignant conditions and adenocarcinoma with a single standardized health measure instrument. METHODS Cross-sectional nationwide study of patients und...
We prove uniqueness of stationary equilibria in a one-dimensional model of bargaining with quadratic utilities, for an arbitrary common discount factor. For general concave utilities, we prove existence and uniqueness of a “minimal” stationary equilibrium and of a “maximal” stationary equilibrium. We provide an example of multiple stationary equilibria with concave (non-quadratic) utilities. Jo...
Suppose n Bayesian agents need to make a decision as a group. The group as a whole is also supposed to be a Bayesian agent whose probabilities and utilities are derived or aggregated in reasonable ways from the probabilities and utilities of the group members. The aggregation could be ex ante, i.e., in terms of expected utilities, or it could be ex post, i.e., in terms of utilities only, or in ...
Benchmarking the performance of human antibody gene alignment utilities using a 454 sequence dataset
MOTIVATION Immunoglobulin heavy chain genes are formed by recombination of genes randomly selected from sets of IGHV, IGHD and IGHJ genes. Utilities have been developed to identify genes that contribute to observed VDJ rearrangements, but in the absence of datasets of known rearrangements, the evaluation of these utilities is problematic. We have analyzed thousands of VDJ rearrangements from an...
In order to remain competitive in a deregulated environment, a group of European Utilities developed a prototype of a single Marketplace called e-utilities•com whose mandate is a clear customer centric orientation in the European environment for a successful mid-term multi-utility business via the Web. This paper highlights the concept of e-utilities•com and its implementation in a Web portal.
Following up on the work of Megiddo and Vazirani [10], who determined continuity properties of equilibrium prices and allocations for perhaps the simplest market model, Fisher’s linear case, we do the same for: – Fisher’s model with piecewise-linear, concave utilities – Fisher’s model with spending constraint utilities – Arrow-Debreu’s model with linear utilities – Eisenberg-Gale markets.
Most approaches to mining association rules implicitly consider the utilities of the itemsets to be equal. We assume that the utilities of itemsets may differ, and identify the high utility itemsets based on information in the transaction database and external information about utilities. Our theoretical analysis of the resulting problem lays the foundation for future utility mining algorithms.
Integrated resource planning (IRP) is a new way for utilities and state regulatory commissions to consistently assess a variety of demand and supply resources to cost-effectively meet customer energy-service needs. This paper reviews recent progress in IRP and identifies the need for additional work by utilities, regulatory commissions, and other organizations. Kevwords: demand-side management,...
Society is often guilty of taking our buried utilities for granted. However, just like every other type of infrastructure, their neglect can have catastrophic effects. Therefore urgent attention is needed in order to facilitate and improve upon the current buried utilities maintenance techniques. The underground world is sometimes denser than the above-ground world. A classic example of this is...
Various preference-based measures of health are available for use as an outcome measure in cost-utility analysis. The aim of this study is to compare two such measures EQ-5D and SF-6D in mental health patients. Baseline data from a Dutch multi-centre randomised trial of 616 patients with mood and/or anxiety disorders were used. Mean and median EQ-5D and SF-6D utilities were compared, both in th...
