Examining the Merits of Dual Regulation for Single-Stock Futures: How the Divergent Insider Trading Regimes for Federal Futures and Securities Markets Demonstrate the Necessity for (and Virtual Inevitability of) Dual CFTCSEC Regulation for Single-Stock Futures
[Excerpt] Single-stock futures are a recent addition to the financial landscape in the United States and provide retail and institutional investors with a new tool for investment or speculation. So far, the market response to these instruments has been cool. Some observers have argued that the regulatory framework for single-stock futures is a cause of the lack of investor interest. Single-stock futures are regulated by both the Commodities Futures Trading Commission (“CFTC”) and the Securities and Exchange Commission (“SEC”), and this system of dual regulation has been criticized as overly burdensome and unnecessary

Gait development in African elephant calves
Most descriptions of elephant locomotion recognize only one gait: the lateral sequence walk. In contrast, several studies on African elephants (Loxodonta africana) have indicated that elephants use at least two other gaits: an amble and a trot. Other animals modify their gaits over the lifespan, but there is no published research on the gaits of elephant calves. The present study examines gait development in African elephant calves born at the Indianapolis Zoo between 2000 and 2015. I conducted frame-by-frame analysis on the gait samples of six calves across two time periods: Early (zero to six months of age) and Late (two to three years). I analyzed 90 gait samples and combined them with archived data on the same calves in order to have sample sizes sufficient for meaningful comparison. Gait diagrams, on which the variables “Duty Factor” and “Phase Lag” are plotted, showed that the calves exhibited two gaits: Lateral sequence walks and walking trots. Comparisons between the two time periods indicated 1) the relative frequency of trotting was similar at both ages, 2) the mean lateral sequence Phase Lag was similar at both ages, 3) a decrease in the Phase Lag variability of lateral sequence gaits, and 4) consistent with the increase in body size, the mean stride duration was longer in the Late period. Since the frequency of trotting was similar in the Early and Late periods, the reduction in trotting typical in adults must occur at a later age

Application of LANDSAT data to delimitation of avalanche hazards in Montane, Colorado
The author has identified the following significant results. Photointerpretation of individual avalanche paths on single band black and white LANDSAT images is greatly hindered by terrain shadows and the low spatial resolution of the LANDSAT system. Maps produced in this way are biased towards the larger avalanche paths that are under the most favorable illumination conditions during imaging; other large avalanche paths, under less favorable illumination, are often not detectable and the smaller paths, even those defined by sharp trimlines, are only rarely identifiable
An Efficient Algorithm for Clustering of Large-Scale Mass Spectrometry Data
High-throughput spectrometers are capable of producing data sets containing
thousands of spectra for a single biological sample. These data sets contain a
substantial amount of redundancy from peptides that may get selected multiple
times in a LC-MS/MS experiment. In this paper, we present an efficient
algorithm, CAMS (Clustering Algorithm for Mass Spectra) for clustering mass
spectrometry data which increases both the sensitivity and confidence of
spectral assignment. CAMS utilizes a novel metric, called F-set, that allows
accurate identification of the spectra that are similar. A graph theoretic
framework is defined that allows the use of F-set metric efficiently for
accurate cluster identifications. The accuracy of the algorithm is tested on
real HCD and CID data sets with varying amounts of peptides. Our experiments
show that the proposed algorithm is able to cluster spectra with very high
accuracy in a reasonable amount of time for large spectral data sets. Thus, the
algorithm is able to decrease the computational time by compressing the data
sets while increasing the throughput of the data by interpreting low S/N
spectra.Comment: 4 pages, 4 figures, Bioinformatics and Biomedicine (BIBM), 2012 IEEE
