We reconsider the toy model studied in [1] of a spatially closed Friedmann-Lemâıtre universe, driven by a massive scalar field, which deflates quasi-exponentially, bounces and then enters a period of standard inflation. We find that the equations for the matter density perturbations can be solved analytically, at least at lowest order in some “slow-roll” parameter. We can therefore give, in tha...

This paper presents a nonlinear model of U.S. GDP growth dynamics that allows for a post-recession “bounce-back” effect in the level of GDP. While a number of studies have attempted to capture such an effect using ad hoc recession-based dummy variable methods, we endogenously estimate this business cycle asymmetry using an extended version of Hamilton's (1989) Markov-switching model. Like Hamil...

Modeling blood flow in larger vessels using lattice-Boltzmann methods comes with a challenging set of constraints: a complex geometry with walls and inlets and outlets at arbitrary orientations with respect to the lattice, intermediate Reynolds (Re) number, and unsteady flow. Simple bounce-back is one of the most commonly used, simplest, and most computationally efficient boundary conditions, b...

of the ground bounce in digital CMOS circuits. First, an analytical method for calculating of the ground bounce is presented. The proposed method relies on accurate models of the short-channel MOS device and the chip-package interface parasitics. Next the effect of ground bounce on the buffer propagation delay and the optimum taper factor is discussed and a mathematical relationship for total p...

Why do some people bounce back from life's hardships while others despair? HBR senior editor Diane Coutu looks at the nature of individual and organizational resilience, issues that have gained special urgency in light of the recent terrorist attacks, war, and recession. In the business arena, resilience has found its way onto the list of qualities sought in employees. As one of Coutu's intervi...

All coastal systems experience disturbances and many across the planet are under unprecedented threat from an intensification of a variety stressors. The West Antarctic Peninsula is hotspot physical climate change has experienced dramatic loss sea-ice glaciers in recent years. Among other things, immobilizes icebergs, reducing collisions between icebergs seabed, thus decreasing ice-scouring. Ic...

Although organisational resilience is crucial to small and medium-sized enterprises (SMEs) in turbulent business environments, research has yet establish whether how human resource management (HRM) systems can help build an SME's influence firm performance. Drawing on the perspective of HRM as internal capability builder capital theory, we develop a model that depicts high-performance work (HPW...

This paper is concerned with the analysis and optimization of the ground bounce in digital CMOS circuits. First, an analytical method for calculating the ground bounce is presented. The proposed method relies on accurate models of the short-channel MOS device and the chip-package interface parasitics. Next the effect of ground bounce on the propagation delay and the optimum tapering factor of a...
