We carry out a fluctuation analysis of the non-abelian Born-Infeld action up to order F 6 in the presence of a background intersecting D-branes system. We compare the mass spectrum which is obtained in our analysis to the spectrum derived from the worldsheet analysis. The mass spectra completely agree with each other. This result provides a strong support for the claim that the action we analyz...

We investigate the dependence of ellipticities of clusters of galaxies on cos-mological parameters using large-scale cosmological simulations. We determine cluster ellipticities out to redshift unity for LCDM models with different mean densities Ω m and amplitudes of mass fluctuation σ 8,0. The mean ellipticity increases monotonically with redshift for all models. Larger values of σ 8,0 , i.e.,...

We compare the mass spectrum which is obtained in our analysis to the spectrum derived from the worldsheet analysis. The mass spectra completely agree with each other.

In the context of the two fluid model of space-time fluctuations proposed to tame the transplanckian problem encountered in black hole physics, it is postulated that the inflaton is the fluctuation of mode density, “the vapor component” of the model. The mass of the inflaton is occasioned by the exchange of degrees of freedom between the “vapor” and the “liquid”, the planckian “soup” in which u...

A 6-component “wave function” (not field, but S-matrix interpretable) for a massive spin-1 particle parallels the Dirac “chiralitydoubled” 4-component wave function for a spin-1/2 particle, by pairing two wave functions for same spin but opposite “handedness”. The correlated “opposite-parity” pair of complex 3-vectors defines a fluctuating spin-correlated lightlike “internal velocity” as well a...

In an attempt to explore the possibly adaptive function obesity may serve for some women with histories of sexual trauma, we examined relationships among sexual abuse history, body dissatisfaction, and maximum weight fluctuation among obese (n = 38; Body Mass Index > or = 27.3) and nonobese (n = 112; Body Mass Index < 27.3) women sampled from a primary care medical setting. History of sexual ab...
