abstract background and aim: the intolerance of uncertainty model was initially developed as an explanation for worry within the context of generalized anxiety disorder. however, recent research has identified intolerance of uncertainty (iu) as a transdiagnostic maintaining factor across the anxiety disorders. the aim of the present study was to compare the intolerance of uncertainty in patient...

In this paper, we consider the node-restricted minmax regret 1-median problem on a tree network where node weights are deterministic and edge lengths are subject to uncertainty with unknown symmetric distribution. There have been proposed some complicated and time-consuming algorithms to obtain robust solutions for robust 1-median problem. We formulate the robust regret function as a mixed inte...

We study necessary and sufficient conditions for information to aggregate in a stylized one-shot unit-demand uniform-price prediction market. We show that, in the increasing symmetric equilibrium, the market price properly aggregates information if and only if (i) the number of realized trades is non-negligible compared to number of market participants, and (ii) there is no uncertainty about th...

—Mrs. Gerber's Lemma lower bounds the entropy at the output of a binary symmetric channel in terms of the entropy of the input process. In this paper, we lower bound the output entropy via a different measure of input uncertainty, pertaining to the minimum mean squared error (MMSE) prediction cost of the input process. We show that in many cases our bound is tighter than the one obtained from M...

A positive de…nite symmetric matrix quali…es as a quantum mechanical covariance matrix if and only if + 12 i~ 0 where is the standard symplectic matrix. This well-known condition is a strong version of the uncertainty principle, which can be reinterpreted in terms of the topological notion of symplectic capacity, closely related to Gromov’s non-squeezing theorem. We show that a recent re…nement...

A simple model is presented for the parton distributions in hadrons. The parton momenta in the hadron rest frame are derived from a spherically symmetric, Gaussian, distribution having a width motivated by the Heisenberg uncertainty relation applied to the hadron size. Valence quarks and gluons originate from the ‘bare’ hadron, while sea partons arise mainly from pions in hadronic fluctuations....

When an irreversible decision is taken under uncertainty there is an option value of delay. If a small number of agents are in competition each one’s ability to delay is restricted by the fear of preemption, seeming to undermine the real options approach. We present a model in which two firms may invest in competing research projects with uncertain returns. Two distinct types of equilibria aris...

Generalized concept lattices have been recently proposed to deal with uncertainty or incomplete information as a non-symmetric generalization of the theory of fuzzy formal concept analysis. On the other hand, concept lattices have been defined as well in the framework of fuzzy logics with non-commutative conjunctors. The contribution of this paper is to prove that any concept lattice for noncom...

In an economy with a fixed exchange rate regime that suffers an adverse shock, we study the delay strategies of speculators that may trigger an endogenous devaluation before it occurs exogenously. The game played by the speculators has a unique symmetric Nash equilibrium which is a strongly rational expectation equilibrium. A higher uncertainty about the initial level of reserves of the Central...

We examine basic properties of complementarity by using the most general description of quantum observables as positive-operator measures. We show that, in general, two observables can be complementary or not depending on the measure of fluctuations adopted and that complementarity is not a symmetric relation. This occurs because the states that determine the measured statistics do not necessar...
