We discovered that the optical to near-infrared properties of Gigahertz Peaked Spectrum (GPS) galaxies are consistent with them having old stellar populations , with little or no contamination from their active nuclei. They seem to be a homogeneous class of object, in luminosity and scatter comparable to rst ranked cluster galaxies. At z 1 the K band luminosities are about a magnitude fainter t...

Is the stock market boom a result of the baby boom? This paper develops an overlapping generations model in which a baby boom is modeled as a high realization of a random birth rate, and the price of capital is determined endogenously by a convex cost of adjustment. A baby boom increases national saving and investment and thus causes an increase in the price of capital. The price of capital is ...

Recently, a non-abelian factorization problem together with an associated asymmetric encryption scheme were introduced in [1]. We show how a classical baby-step giant-step algorithm for discrete logarithm can be extended to this problem. This contradicts the claims regarding the complexity of the proposed problem.

This paper studies giant magnons in CP , which in all known cases are old solutions from S placed into twoand three-dimensional subspaces of CP , namely CP , RP 2 and RP . We clarify some points about these subspaces, and other potentially interesting threeand four-dimensional subspaces. After confirming that ∆ − (J1 − J4)/2 is a Hamiltonian for small fluctuations of the relevant ‘vacuum’ point...

We study general rotating string solution in the AdS4×CP background with a BNS holonomy turned on over CP 1 ⊂ CP. We find the giant magnon and single spike solutions for the string moving in this background corresponding to open spin chain. We calculate the corresponding dispersion relation among various conserved charges for both the cases. We further study the finite size effect on both the g...

A phenomenological schematic model of multipole giant resonances (GR) is considered which treats the external interaction via common decay channels on the same footing as the coherent part of the internal residual interaction. The damping due to the coupling to the sea of complicated states is neglected. As a result, the formation of GR is governed by the interplay and competition of two kinds ...

We report a case of a giant adrenal pseudocyst, found incidentally in a 45 year old female. Her CT scan showed a 7.5cm x 7.3cm suprarenal mass and she underwent a laparoscopic transperitoneal adrenalectomy. We report this case and review the literature regarding the diagnosis and management of adrenal pseudocysts.
