Developing automated assembly systems normally happens in two distinct stages: rst an \o -line" stage in which the system is designed and programmed in simulated and then an \on-line" stage in which the simulation results are used to minimize the deployment and integration time of the physical machines. The distinction is so great that usually completely di erent software environments are used ...

Preheating after inflation may lead to non-thermal phase transitions with symmetry restoration. These phase transitions may occur even if the total energy density of fluctuations produced during reheating is relatively small as compared with the vacuum energy in the state with restored symmetry. As a result, in some inflationary models one encounters a secondary, non-thermal stage of inflation ...

This paper describes the stability of the stages of change concept of the Transtheoretical Model for three different nutrition behaviors (fat, fruit and vegetable intake) among adult individuals who are unexposed to planned interventions. Secondary analyses were conducted on data collected in control groups (n = 386 and n = 739) of two intervention studies in the Netherlands. Data on dietary in...

The population dynamics of infectious diseases occasionally undergo rapid qualitative changes, such as transitions from annual to biennial cycles or to irregular dynamics. Previous work, based on the standard seasonally forced 'susceptible-exposed-infectious-removed' (SEIR) model has found that transitions in the dynamics of many childhood diseases result from bifurcations induced by slow chang...

OBJECTIVES The purpose of the study was to examine the frequency of burdensome care transitions at the end of life, the difference between different types of residential care facilities, and the changes occurring between 2002 and 2008. DESIGN A nationwide, register-based retrospective study. SETTING Residential care facilities offering long-term care, including traditional nursing homes, sh...

Few studies have focused on the care setting transitions that occur in the last year of life. People living in rural areas may have more difficult care setting transitions and also more moves in the last year of life as health changes occur. A mixed-methods study was conducted to gain an understanding of the number and implications or impact of care setting transitions in the last year of life ...

The cross-section distribution of U.S. wealth is more skewed than the labor earnings. Stachurski and Toda (2019) explain how plain vanilla Bewley-Aiyagari-Huggett (BAH) models with infinitely lived agents can't generate that pattern because an equilibrium risk-free rate lower time preference each person's process stationary. We provide two modifications a BAH model this pattern: (1) overlapping...

A unified picture of the scaling and non-scaling behavior in quantum Hall plateau transitions is proposed. We show that the interband mixing of states with opposite chiralities and the degrees of the inter-Landau-band overlap are the key ingredients to the problem. We find that the mixing of states with opposite chiralities tends to delocalize electronic states, leading to the formation of exte...

We address the problem of MCMC analysis of a complex ecological system using a Bayesian inferential approach. We describe a complete likelihood framework for the life history of the wavyleaf thistle, including missing stages and density dependence. We indicate how, in order to make inference on life history transitions involving both missing information and density dependence, the stochastic mo...
