Although forest fragmentation and degradation have been recognized as one of major threats to wild panda population, little is known about the relationship between panda distribution and forest fragmentation. This study is unique as it presents a first attempt at understanding the effects of forest fragmentation on panda spatial distribution for the entire wild panda population. Using a moving ...

The non-linear nature of string theory on non-trivial backgrounds related to the AdS/CFT correspondence suggests to look for simplifications. Two such simplifications proved to be useful in studying string theory. These are the pp-wave limit which describes point-like strings and the so called “near flat space” limit which connects two different sectors of string theory – pp-waves and “giant ma...

We investigate giant magnons from classical rotating strings in two different backgrounds. First we generalize the solution of Hofman and Maldacena and investigate magnon excitations of a spin chain which are dual to a string on R× S with three nonvanishing angular momenta. We find a dispersion relation similar to that of Hofman and Maldacena and to the one found by Dorey for the two spin case ...

This paper describes a study conducted in the summer of 2006 aimed at exploring the play patterns and lifestyles of gamers who fall into the loose demographic of “Baby Boomers,” typically defined as people born between 1946 and 1964. This independent study, including over 300 participants, combined quantitative and qualitative techniques in order paint a multi-faceted picture of the gaming life...

This review is dedicated to electric field effects on giant unilamellar vesicles, a cell-size membrane system. We summarize various types of behavior observed when vesicles are subjected either to weak AC fields at various frequency, or to strong DC pulses. Different processes such as electrodeformation, -poration and -fusion of giant vesicles are considered. We describe some recent development...

There are estimated to be between 1.4 and 3.8 million LGBT Americans over the age of 65. This population is expected to increase between 3.6 and 7.2 million due to the Baby Boom generation. The older adult population is the most rapidly growing age group in the United States and experiences normal age-related changes in cognition as well as in internal and external physical health. Although dif...

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...
