4-Hydroxynonenal (4-HNE) is a peroxidation product of ˆ-6-poly-unsaturated fatty acids and exerts growth modifying as well as cytotoxic activities. This aldehyde component of oxidized lipid is increased during the aging process. In this study, to characterize the potential role of the lipid peroxidation product in aging, we studied the effects of 4-HNE on cell proliferation and activation of ce...

I Over the last decade or so, much has been written about the new "science of complexity". From journalistic hyperbole to cutting edge research, it is widely assumed that the science of complexity has indeed discovered something new, that is worthy of the attention of scientists and philosophers alike. But what? An overarching principle that connects the study of complex systems across the phys...

We explore the minimum energy configurations of repelling particles distributed over n possible locations forming a toric grid. We conjecture that the most energy-efficient way to distribute n/2 particles over this space is to place them in a checkerboard pattern. Numerical experiments validate this conjecture for reasonable choices of the repelling force. In the present paper, we prove this co...

In English (1) tense is marked both on auxiliary do and the lexical verb. In (2), is occurs in two positions. In (3), the functional element no is realized in a relative clause, even though adult Japanese has no overt functional morpheme in this position. In (4), the ‘bound noun’ kes is likewise realized in a relative clause, even though no morpheme appears in this position in adult Korean. The...

Xuan Leng1 and Liang Peng2 Abstract. Motivated by a recent discovery that the two-step inference for Lee-Carter mortality model is inconsistent when the mortality index does not follow from a nearly integrated AR(1) process, we propose a test for unit root in a Lee-Carter model with an AR(2) process for the mortality index. Although testing for a unit root has been studied extensively in econom...

1550-7998=20 The Lee model was introduced in the 1950s as an elementary quantum field theory in which mass, wave function, and charge renormalization could be carried out exactly. In early studies of this model it was found that there is a critical value of g2, the square of the renormalized coupling constant, above which g0, the square of the unrenormalized coupling constant, is negative. Thus...

We study the relativistic Lee model in static Riemannian manifolds. The model is constructed through its resolvent, which is based on the socalled principal operator and the heat kernel techniques. It is shown that making the principal operator well-defined dictates how to renormalize the parameters of the model. The underlying geometry is found not to affect the ultra-violet behavior of the th...
