It is shown that the formula for the Möbius pseudodistance for the annulus yields better estimates than previously known for the constant in the Bergman space maximum principle.

This paper is the second part in a series that provides a comprehensive survey of the problems and techniques of tracking maneuvering targets in the absence of the so-called measurement-origin uncertainty. It surveys motion models of ballistic targets used for target tracking. Models for all three phases (i.e., boost, coast, and reentry) of motion are covered.

A generalized uncertainty relation for an entangled pair of particles is obtained if we impose a symmetrization rule for all operators that we should use when doing any calculation using the entangled wave function of the pair. This new relation reduces to Heisenberg’s uncertainty relation when the particles have no correlation and suggests that we can have new lower bounds for the product of p...

Only about 1,000 qualitatively different protein folds are believed to exist in nature. Here, we review theoretical studies which suggest that some folds are intrinsically more designable than others, i.e. are lowest energy states of an unusually large number of sequences. The sequences associated with these folds are also found to be unusually thermally stable. The connection between highly de...

In McLean and Postlewaite (Econometrica 56, 1992, p. 2421), we analyzed pure exchange economies with asymmetrically informed agents. We defined a notion of informational size and showed that, when the aggregate information of all agents resolves nearly all the uncertainty regarding the state of nature, the conflict between incentive compatibility and (ex post) efficiency can be made small if ag...

In chapter 9 of Knowledge and its Limits, Timothy Williamson argues for the thesis that the evidence that a subject has is constituted by propositions known by the subject (a thesis that he summarizes in the equation E=K). Moreover, Williamson also argues that whatever justifies a subject in believing a proposition is part of that subject’s evidence, and thus that only propositions that a subje...

In contrast to a focus on efficiency, we advocate aggressive usage of available resources. This view is embodied in what we call the Buffet principle: continue using more resources as long as the marginal cost can be driven lower than the marginal benefit. We illustrate through several examples how this seemingly obvious principle is not adhered to by many common designs and how its application...

background: this study explored the state of hematopoietic stem cell transplantation (hsct) recipient patients and problems experienced by them and nurse about these state and problems, in iran. methods: qualitative content analysis was used for analyzing semi-structured interviews with 12 hsct recipient patients and 18 nurses. results: three main categories described the hsct state and problem...

age replacement policy is concerned with finding an optional time tominimize the cost, at which time the unit is replaced even if itdoes not fail. so far, age replacement policy involving random agehas been proposed. this paper will assume the age of the unit is anuncertain variable, and find the optimal time to replace the unit.
