Aging can be loosely defined as the accumulation of changes within an organism over time. Aging is a complex, poorly understood, and multi-factorial process. It is generally regarded as progressive, irreversible, deleterious, and endogenous in nature [1]. Over 300 scientific theories seeking to explain the specifics of the process of aging have been posited. Yet, despite the vast amount of rese...

Nucleon electromagnetic form factors are studied in the cloudy bag model with center-of-mass and recoil corrections. The center of mass motion is eliminated via several different momentum projection techniques and the results for these are compared. It is found that the shapes of these form factors are significantly improved with respect to data if the Lorentz contraction of the internal struct...

This paper investigates the growth factors of EU regions in the 1990s. We test the hypothesis that regional growth is determined by endogenous growth factors, trade and technological catching-up in a growth accounting framework. Our estimations suggest that growth of EU regions is positively related to the accumulation of physical and human capital. Innovation activity as well as international ...

Personal income distributions in Japan are analyzed empirically and a simple stochastic model of the income process is proposed. Based on empirical facts, we propose a minimal two-factor model. Our model of personal income consists of an asset accumulation process and a wage process. We show that these simple processes can successfully reproduce the empirical distribution of income. In particul...
