Sympathetic Cooling of Lithium by Laser-cooled Cesium
We present first indications of sympathetic cooling between two neutral,
optically trapped atomic species. Lithium and cesium atoms are simultaneously
stored in an optical dipole trap formed by the focus of a CO laser, and
allowed to interact for a given period of time. The temperature of the lithium
gas is found to decrease when in thermal contact with cold cesium. The
timescale of thermalization yields an estimate for the Li-Cs cross-section.Comment: 4 pages, proceedings of ICOLS 200
A valuation model for firms with stochastic earnings
In this paper, a model is set up for valuing a firm with stochastic earnings. It is assumed that the earnings of the considered firm follow a time-varying mean reverting stochastic process. It is shown that the value of the firm satisfies a boundary value problem of a second-order partial differential equation, which can be solved numerically. Special cases are discussed. Analytic solution is found for one special case. Moreover it is shown that the analytic solution is consistent with a previous result obtained by other researchers.stochastic earnings, firm valuation, debt valuation

Online Students Develop Marketable Professional Skills
Article published in EDUCAUSE Review, about professional skills developed while taking online courses at Columbia University School of Social Work (CSSW).
Students preparing to take online courses anticipated gaining professional skills in addition to their online learning of the course content. A survey of the marketable skills students wanted to obtain found that 38 percent chose all 10 of the professional options offered as possible answers. The top three skills students wanted to gain were "Confidence with online technologies and environments," "Self-motivation, initiative, and independent learning," and "Experience with multiple types of online software.”

Comments on hydrographic and topographic LIDAR acquisition and merging with multibeam sounding data acquired in the Olympic Coast National Marine Sanctuary
In April 2005, a SHOALS 1000T LIDAR system was used as an efficient alternative for safely acquiring data to describe the existing conditions of nearshore bathymetry and the
intertidal zone over an approximately 40.7 km2 (11.8 nm2) portion of hazardous coastline within the Olympic Coast National Marine Sanctuary (OCNMS). Data were logged from
1,593 km (860 nm) of track lines in just over 21 hours of flight time. Several islands and offshore rocks were also surveyed, and over 24,000 geo-referenced digital still photos were captured to assist with data cleaning and QA/QC. The 1 kHz bathymetry laser obtained a maximum water depth of 22.2 meters. Floating kelp beds, breaking surf lines and turbid water were all challenges to the survey. Although sea state was favorable for this time of the year, recent heavy rainfall and a persistent low-lying layer of fog reduced acquisition productivity. The existence of a completed VDatum model covering this same geographic region permitted the LIDAR data to be vertically transformed and
merged with existing shallow water multibeam data and referenced to the mean lower low water (MLLW) tidal datum. Analysis of a multibeam bathymetry-LIDAR difference
surface containing over 44,000 samples indicated surface deviations from –24.3 to 8.48 meters, with a mean difference of –0.967 meters, and standard deviation of
1.762 meters. Errors in data cleaning and false detections due to interference from surf, kelp, and turbidity likely account for the larger surface separations, while the remaining general surface difference trend could partially be attributed to a more dense data set, and shoal-biased cleaning, binning and gridding associated with the multibeam data for maintaining conservative least depths important for charting dangers to navigation.

A new class of parallel data convolutional codes
We propose a new class of parallel data convolutional
codes (PDCCs) in this paper. The PDCC encoders inputs
are composed of an original block of data and its interleaved version.
A novel single self-iterative soft-in/soft-out a posteriori probability
(APP) decoder structure is proposed for the decoding of
the PDCCs. Simulation results are presented to compare the performance
of PDCCs
Introduction to Asian Culture(s) and Globalization
Marshall McLuhan coined the term the global village associating globalized human experiences in an electronic age (4). Although transnational relations existed for many centuries, McLuhan predicted in the 1960s that new technologies not only facilitate the growth of international interconnectedness, cross-border exchanges, as well as trans-cultural phenomena, but also help foster cultural transactions. Referring to the dramatic and unprecedented break between the past and the present, tradition and modernity, Arjun Appadurai argues that media and migration have been two major forces impelling the circulation of world cultures (3). In the phenomenon of globalization, people from every part of the world tend to embrace the concepts of democracy, human rights, and technical assistance, but globalization did not and does not go smooth in all aspects of life. Globalization was originally characterized as a power to diminish the gap between the developed and developing worlds. However, there continue to be resistance against globalization because of the West\u27s — i.e., technologically and industrially advanced countries with now soft imperial agendas. As Fredric Jameson suggests, globalization has become a philosophical issue because through cultural adaption, integration, and transformation, globalization has triggered the development of mass culture and restructured the production of cultures in various ways (54-60)
Stratigraphy of the Perrine and Nun Sulci quadrangles (Jg-2 and Jg-5), Ganymede
Dark and light terrain materials in the Perrine and Nun Sulci quadrangles are divided into nine map units, four dark, and five light. These are placed in time-stratigraphic sequence primarily by means of embayment and cross-cutting relationships. Dark terrain is generally more heavily cratered and thus older that light terrain but, at least in these quadrangles, crater densities are not reliable indicators of relative ages among the four dark material units. The four mapped material units within dark terrain are: cratered dark materials (dc), grooved dark materials (dg), transitional dark materials (di), and dark materials, undivided (d). The five mapped units within light terrain are: intermediate light materials (li), grooved light materials (lg), irregularly grooved light materials (lgl), smooth light materials (ls), and light materials, undivided
