BoseEinstein Condensation in a Gas of Sodium Atoms
, 1995
"... We have observed BoseEinstein condensation of sodium atoms. The atoms were trapped in a novel trap that employed both magnetic and optical forces. Evaporative cooling increased the phasespace density by 6 orders of magnitude within seven seconds. Condensates contained up to 5 3 10 5 atoms at dens ..."

at densities exceeding 10 14 cm 23 . The striking signature of Bose condensation was the sudden appearance of a bimodal velocity distribution below the critical temperature of ϳ 2 mK. The distribution consisted of an isotropic thermal distribution and an elliptical core attributed to the expansion of a dense

Identifiability of finite mixtures of elliptical distributions
"... We present general results on the identifiability of finite mixtures of elliptical distributions under conditions on the characteristic generators or density generators. Examples include the multivariate t distribution, symmetric stable laws, exponential power and Kotz distributions. In each case, ..."

Density of rational points on elliptic K3 surfaces
 Asian J. Math
"... Let X be a smooth projective algebraic variety defined over a number field K. We will say that rational points on X are potentially dense if there exists a finite extension K ′ /K such that the set X(K ′ ) of K ′rational points is Zariski dense. What are possible strategies to propagate rational po ..."

On the Origin of Density Cusps in Elliptical Galaxies
, 1998
"... We investigated the dynamical reaction of the central region of galaxies to a falling massive black hole by Nbody simulations. As the initial galaxy model, we used an isothermal King model and placed a massive black hole at around the halfmass radius of the galaxy. We found that the central core o ..."

of the galaxy is destroyed by the heating due to the black hole and that a very weak density cusp (ρ ∝ r −α, with α ∼ 0.5) is formed around the black hole. This result is consistent with recent observations of large elliptical galaxies with Hubble Space Telescope. The velocity of the stars becomes tangentially
DENSITY OF RATIONAL POINTS ON ELLIPTIC SURFACES
"... Abstract. Suppose V is a surface over a number field k that admits two elliptic fibrations. We show that for each integer d there exists an explicitly computable closed subset Z of V , not equal to V , such that for each field extension K of k of degree at most d over the field of rational numbers, ..."
