Inflation and deflation in stock markets
The aim of this paper is to compare statistical properties of a bubble period with those of the anti-bubble period in stock markets. We investigate the statistical properties of daily data for the Nikkei 225 index in the 28-year period from January 1975 to April 2003, corresponded to the periods of bubbles and anti-bubbles. We divide the time series into two parts, the period of inflation (or b...
متن کاملTopologically Robust 3D Shape Matching via Gradual Deflation and Inflation
Despite being vastly ignored in the literature, coping with topological noise is an issue of increasing importance, especially as a consequence of the increasing number and diversity of 3D polygonal models that are captured by devices of different qualities or synthesized by algorithms of different stabilities. One approach for matching 3D shapes under topological noise is to replace the topolo...
متن کاملDeflation-activated receptors, not classical inflation-activated receptors, mediate the Hering-Breuer deflation reflex.
Many airway sensory units respond to both lung inflation and deflation. Whether those responses to opposite stimuli come from one sensor (one-sensor theory) or more than one sensor (multiple-sensor theory) is debatable. One-sensor theory is commonly presumed in the literature. This article proposes a multiple-sensor theory in which a sensory unit contains different sensors for sensing different...
متن کاملInflation from Extra Dimensions
The radial mode of n extra compact dimensions (the radion, b) can cause inflation in theories where the fundamental gravity scale, M , is smaller than the Planck scale MP . For radion potentials V (b) with a simple polynomial form, to get the observed density perturbations, the energy scale of V (b) must greatly exceed M ∼ 1 TeV: V (b) ≡ MV ∼ 10−4MP . This gives a large radion mass and reheat t...
متن کاملInflation and Large Internal Dimensions
The hierarchy problem has been one of the longstanding challenges to theoretical physics. It is a puzzle concerning masses of scalar fields, which are all quadratically divergent in the loop expansion of a generic quantum field theory. Since the natural cut-off of any quantum field theory is the Planck mass Mp, the renormalization effects should drive all scalar masses up to the Planck scale. A...
