The Sun-like star HD 209458 harbors a close-in giant planet which transits across the star’s disk, and thus allows an unprecedented access to the basic parameters of the planet, given a certain knowledge of the basic parameters of the star, namely its mass and radius. We present theoretical stellar evolution model calculations for HD 209458 and discuss the uncertainties involved in deriving the...

Let d ≥ 1, and let u, v : R × R → C be Schwartz space solutions to the Schrödinger equation iut + ∆xu = 0; ivt + ∆xv = 0. The standard L bilinear Strichartz estimate for the Schrödinger equation asserts that ‖uv‖L2t,x(R×Rd) .d M N‖u(0)‖L2x(Rd)‖v(0)‖L2x(Rd) whenever u, v are supported in frequency regions {ξ ∈ R : N ≤ |ξ| ≤ 2N}, {η ∈ R : M ≤ |η| ≤ 2M}, and N ≥ 4M . This estimate has been used ex...

We give an estimate of the Gauss curvature for minimal surfaces in Rm whose Gauss map omits more than m(m + 1)/2 hyperplanes in P(C).

We devise a method to measure the abundance of satellite halos in gravitational lens galaxies, and apply our method to a sample of 7 lens systems. After using Monte Carlo simulations to verify the method, we find that substructure comprises f sat = 0.02 (median, 0.006 < f sat < 0.07 at 90% confidence) of the mass of typical lens galaxies, in excellent agreement with predictions of CDM simulatio...

The SR-based critic learns an estimate of the value function, using the SR as its feature representation. Unlike standard actor-critic methods, the critic does not use reward-based temporal difference errors to update its value estimate; instead, it relies on the fact that the value function is given by V (s) = ∑ s′ M(s, s ′)R(s′), where M is the successor representation andR is the expected re...

this paper investigates the relationship between inflation and growth uncertainty in iran for the period of 1988-2008 by using quarterly data. we employ generalized autoregressive conditional heteroscedasticity in mean (garch-m) model to estimate time-varying conditional residual variance of growth, as a standard measures of growth uncertainty. the empirical evidence shows that growth uncertain...

Given a closed m-dimensional manifold M immersed in R, we estimate its diameter d in terms of its mean curvature H by

PURPOSE The purpose of this investigation was to compare a practical measurement of fat free mass index (FFMI) from bioelectrical impedance analysis (BIA) to the dual energy X-ray absorptiometry (DEXA) value in collegiate athletes. METHODS Thirty-three male baseball players and 16 female gymnasts volunteered to participate in this study during their respective pre-season. Subjects visited the...
