Bouncing alternatives to inflation

Evidence for bouncing evolution before inflation after BICEP2.

The BICEP2 Collaboration reports a detection of primordial cosmic microwave background (CMB) B mode with a tensor-to-scalar ratio r = 0.20(-0.05)(+0.07) (68% C.L.). However, this result disagrees with the recent Planck limit r < 0.11 (95% C.L.) on constraining inflation models. In this Letter we consider an inflationary cosmology with a preceding nonsingular bounce, which gives rise to observab...

Alternatives to Inflation Targeting Monetary Policy for Stable and Egalitarian Growth: A Brief Research Summary

Many countries in the developing world have adopted an approach to monetary policy that focuses on maintaining a low level of inflation, to the exclusion of other important objectives such as employment generation, increasing investment or reducing poverty, despite the widespread evidence that moderate levels of inflation have few or no costs. Some have even adopted formal " inflation targeting...

Bouncing Back

W hen an injury forces an athlete out of training and/or competition, the return-to-play (RTP) decision-making process may be simple or multidimensional. When analyzing these situations, an important factor to consider is why the injury occurred in the first place. Was the injury a result of an unavoidable trauma, such as a hit to the knee in a contact sport, or the result of fatigue or poor co...
