This work continues the generalized stability theory (GST) analysis of baroclinic shear flow in the primitive equations (PE), focusing on the regime in which the mean baroclinic shear and the stratification are of the same order. The Eady model basic state is used and solutions obtained using the PE are compared to quasigeostrophic (QG) solutions. Similar optimal growth is obtained in the PE an...

We examine the empirical relationship between output variability and growth for Britain using data eight centuries covering 1270 to 2014 period. Drawing on economic history literature, we split full sample period into four subperiods use GARCH models measure uncertainty estimate its effect average growth. Within each sub-sample, allow depend state of system, example 2-regime switching model wou...

perturbation of the fluid interface has an exponential growth The Rayleigh–Taylor instability is a gravity driven instability of a contact surface between fluids of different densities. The growth of this instability is sensitive to numerical or physical mass diffusion. h(t) 5 h0e, (1.1) For this reason, high resolution of the contact discontinuity is particularly important. In this paper, we a...

A public health crisis in the process of brownfield land redevelopment (BLR) has frequently appeared in the context of promoting industrial upgrading and de-industrialization in China. Recent discussions on the reasons for this problem centered on the lack of laws, standards, and policies needed to secure the process of BLR. However, we argue that an urban governance approach to BLR can identif...

We theoretically investigate the response of optical phase conjugators to incident probe pulses. In the stable ~subthreshold! operating regime of an optical phase conjugator it is possible to transmit probe pulses with a superluminally advanced peak, whereas conjugate reflection is always subluminal. In the unstable ~abovethreshold! regime, superluminal response occurs both in reflection and in...

We demonstrate experimentally that multiple four-wave mixing (FWM) pumped by a dual-frequency input in a single-mode fiber is modulationally unstable. This collective type of instability leads, in the anomalous dispersion regime, to sideband growth around all orders of FWM. This is in contrast with the normal dispersion regime where our measurements show that FWM exhibits no instability. Our co...

The paper combines Baumol’s model of structural change with a model of aggregate demand growth in the Keynesian–Kaleckian tradition to predict the dynamics of aggregate employment. The model for the demand regime is estimated with – and Baumol’s model for the productivity regime is calibrated on – OECD data. The trajectory for employment predicted by the combination of the two models tracks the...

Fast Ion Instability is studied in the nonlinear regime. It is shown that exponential growth of the linear regime is replaced in this case by the linear dependence on time. Numeric and analytical results are presented describing the beam profile and the beam spectrum in both regimes.
