The underlying problem confronting us in this paper is the determination of precise upper bounds for the moduli of the coefficients in these normalized expansions at » for functions in the classes S and T. This problem for the first two coefficients in each class has already been solved. We note first that since 4> and / are inverse, ai= —bx and a2= —b2, so for these two cases, discussion of on...

This paper presents a vision and a plan for task-completion engines that support humans in solving complex, knowledge-intensive tasks, by providing an integrated environment that caters for all taskrelated activities. We propose three specific use-cases, describe the desired functionality from the users’ perspective, outline the main components of such a system, and discuss evaluation methodolo...

Infants prefer native structures such as familiar faces and languages. Music is a universal human activity containing structures that vary cross-culturally. For example, Western music has temporally regular metric structures, whereas music of the Balkans (e.g., Bulgaria, Macedonia, Turkey) can have both regular and irregular structures. We presented 4- to 8-month-old American and Turkish infant...

We provide a simple overview of some hypoellipticity results with sharp indices for a class of kinetic equations and we outline a general strategy based on some geometrical properties.

The effects of drift on calibrations carried out by comparison have been studied at the National Institute of Standards and Technology for many years, and a number of strategies have been introduced to combat these effects. One strategy, the use of comparison designs which are inherently immune to linear drift, was developed specifically for mass comparison measurements. These techniques, devel...

We address the simultaneous determination of pricing and capacity investment strategies in a multi-period setting under demand uncertainty. In our model a monopolistic firm makes three decisions: capacity investment (or disinvestment), production (inventory), and price, all of which can be specified dynamically as a function of the state of the system. We analyze the optimal joint strategy and ...

We use a state-dependent model where pricing rules are optimal to examine the costs of a money-based disinflation under various assumptions about the credibility of the policy change. Our analysis allows us to relate actual credibility and future inflation inertia to the asymmetry of the price deviation distribution. An important implication of our statedependent setting is that disinflation ca...

Working papers of the Federal Reserve Bank of Cleveland are preliminary materials circulated to stimulate discussion and critical comment on research in progress. They may not have been subject to the formal editorial review accorded official Federal Reserve Bank of Cleveland publications. The views stated herein are those of the authors and are not necessarily those of the Federal Reserve Bank...

Motoneurones retain pride of place as the Sherringtonian ‘final common pathway’. Conceptually, they integrate the various inputs they receive and convert the input to a frequency code which then is conveyed to the muscle to produce force. Aspects of this conversion by the motoneurone have been the subject of much investigation [for reviews see, for example, 1, 2]). I comment on some of the para...

The canonical inflation specification in sticky-price rational expectations models (the new-Keynesian Phillips curve) is often criticized on the grounds that it fails to account for the dependence of inflation on its own lags. In response, many recent studies have employed a “hybrid” sticky-price specification in which inflation depends on a weighted average of lagged and expected future values...
