On the Special Significance of the Latest PAMELA Results in Astroparticle Physics

In continuation of their earlier measurements, the PAMELA group reported data on antiproton flux and $\bar{P}/P$ ratios in 2010 at much higher energies. In past we had dealt with these specific aspects of PAMELA data in great detail and each time we captured the contemporary data-trends quite successfully with the help of a multiple production model of secondary antiprotons with some non-standard ilk and with some other absolutely standard assumptions and approximations. In this work we aim at presenting a comprehensive and valid description of all the available data on antiproton flux and the nature of $\bar{P}/P$ ratios at the highest energies reported so far by the PAMELA experiment in 2010. The main physical implication of all this would, in the end, be highlighted.Comment: 8 pages, 6 figure

Recent Results on B Meson Oscillations

This paper presents recent time-dependent measurements of neutral B meson oscillations. Similar to the $K^0$--$\bar{K}^0$ system, there are two such systems involving the b quark: $B_d^0$--$\bar{B}_d^0$ and $B_s^0$--$\bar{B}_s^0$. Thus the physical states are respectively $K_{S}$ and $K_{L}$, $(B_d)_S$ and $(B_d)_L$, and $(B_s)_S$ and $(B_s)_L$. The oscillation between each pair of states can be used to determine their mass difference. The present world average for the $(B_d)_S$--$(B_d)_L$ mass difference is $\Delta m_d = 0.457\pm0.019 ps^{-1}$ (or $(3.01\pm0.13)\times 10^{-4}$ eV). Using $f_{B_s}$ = 12\% (the fraction of $B_s$ produced in b events), the current lower limit on the corresponding $\Delta m_s$ is 6.1 ps$^{-1}$ (or $4.0\times 10^{-3}$ eV).Comment: Invited talk at the XVII International Symposium on Lepton-Photon Interactions, Beijing, China, 1995. 26 pages, latex, 15 figure

Non-stabilizing Flexibility:From the Contributions By Keynes and Kalecki Towards a Post-Keynesian Approach

New and old mainstream macroeconomics argues that price flexibility stabilizes the economy. After a decline in aggregate demand, the more rapid prices fall, the faster output returns to its full employment level. The theoretical basis for this result is the well known "Pigou effect". However both Keynes and Kalecki rejected the thesis that price flexibility, in a demand-induced recession, can be stabilizistabilizing. This paper seeks to contrast Keynes's and Kalecki's ideas with the mainstream and discuss and alternative approach in the spirit of the post-keynesian's debt-deflation school.Non-stabilizing flexibily; Pigou effect: Fisher effect; Debt-deflation
