A feedback-based scheme for energy conservative cooperative content distribution for mobile systems is presented together with analysis of its behavior in simulated operation. The mechanism described is designed to address problems of co-operation in transient groups, where group members are assumed to act selfishly to preserve their limited resources. Properties of the resulting barter-trade l...

High school education is central to adolescent socialization and has important downstream consequences for adult life. However, scholars examining schooling’s political effects have struggled to reconcile education’s correlation with both more liberal social attitudes and greater income. To disentangle this relationship, I exploit a major school leaving age reform in Great Britain that caused a...

Central giant cell granuloma (CGCG) is a benign jaw lesion predominantly found in the mandible of young female patients with a variable clinical behavior. Although surgical management is regarded as the main treatment modality for this lesion, the use of intralesional injections of steroids has been recently advocated for its treatment. In addition to this conservative management, the use of fi...

This paper analyzes the behavior of a variety of tracking algorithms for single layer threshold networks in the presence of random drift. We use a system identiication model to model a target network where weights slowly change and a tracking network. Tracking algorithms are divided into conservative and nonconservative algorithms. For a random drift rate of , we nd upper bounds for the general...

We show that the well established Olami-Feder-Christensen (OFC) model for the dynamics of earthquakes is able to reproduce a striking property of real earthquake data. Recently, it has been pointed out by Abe and Suzuki that the epicenters of earthquakes could be connected in order to generate a graph, with properties of a scale-free network of the Barabási-Albert type. However, only the noncon...

We present an efficient second-order accurate scheme to treat stiff source terms within the framework of higher order Godunov’s methods. We employ Duhamel’s formula to devise a modified predictor step which accounts for the effects of stiff source terms on the conservative fluxes and recovers the correct isothermal behavior in the limit of an infinite cooling/ reaction rate. Source term effects...

Evaluation of intervention effects on multiple outcomes is a common scenario in clinical studies. In longitudinal studies, such evaluation is a challenge if one wishes to adequately capture simultaneous data behavior. In this situation, a common approach is to analyze each outcome separately. As a result, multiple statistical statements describing the intervention effect need to be reported and...

Abstract. A conservative cascade is an iterative process that fragments a given set into smaller and smaller pieces according to a rule which preserves the total mass of the initial set at each stage of the construction almost surely and not just in expectation. Motivated by the importance of conservative cascades in analyzing multifractal behavior of measured Internet traffic traces, we consid...

To prevent erratic behavior during runtime checking, JML only allows assertions to call pure, i.e., side-effect free, methods. However, JML’s notion of purity checking is too conservative. For example, Object’s equals method needs to be used in assertions, but some classes use side effects in their equals method to maintain hidden caches or to trigger lazy evaluation, and so these methods canno...

Some dynamical properties for a time dependent Lorentz gas considering both the dissipative and non dissipative dynamics are studied. The model is described by using a four-dimensional nonlinear mapping. For the conservative dynamics, scaling laws are obtained for the behavior of the average velocity for an ensemble of non interacting particles and the unlimited energy growth is confirmed. For ...
