چکیده
ABSTRACT Recent CHIME/FRB observations of the periodic repeating fast radio bursts (FRB) 180916B have produced a homogeneous sample 44 bursts. These permit redetermination modulation period and phase window, in agreement with earlier results. If periodicity results from precession an accretion disc, analogy those Her X-1, SS 433, many other superorbital periods, width observable window indicates that disc axis jitters by angle about 0.14 inclination angle, similar to ratio well-observed jittering jet source 433.

Part 6 : Reference Clock Jitter and Data Jitter 1 Reference Clock Jitter and Data Jitter
Reference clock jitter sets the ultimate limit on the bit error ratio of a serial data system. The traditional techniques for quantifying jitter on clock signals don’t help system designers estimate the clock’s contribution to the total jitter defined at a bit error ratio. New techniques are being introduced to model how transmitters and receivers use reference clocks so that the system RJ and ...
متن کاملA Guide to FRB/US
FRB/US is a large-scale quarterly econometric model of the U.S. economy, developed to replace the MPS model. Most behavioral equations are based on specifications of optimizing behavior containing explicit expectations of firms, households, and financial markets. Although expectations are explicit, the empirical fits of the structural descriptions of macroeconomic behavior are comparable to tho...
متن کاملNeoclassical Miracles - GMPI events - FRB Dallas
We study the dynamic behavior of a Neoclassical growth model with finite lifetimes and imperfect altruism in which individuals can accumulate both physical and human capital. We use the model to better understand and explain the behavior of economic miracles. Our results suggest that standard Neoclassical forces can account for the performance of the miracle economies and can explain the protra...

Spin precession and avalanches.
In many magnetic materials, spin dynamics at short times are dominated by precessional motion as damping is relatively small. We describe how avalanches evolve under these conditions. The growth front is spread out over a large region and consists of rapidly fluctuating spins often above the ferromagnetic transition temperature. In the limit of no damping the system will transition to an ergodi...
