Method for producing oxygen from lunar materials
This invention is related to producing oxygen from lunar or Martian materials, particularly from lunar ilmenite in situ. The process includes producing a slurry of the minerals and hot sulfuric acid, the acid and minerals reacting to form sulfates of the metal. Water is added to the slurry to dissolve the minerals into an aqueous solution, the first aqueous solution is separated from unreacted minerals from the slurry, and the aqueous solution is electrolyzed to produce the metal and oxygen

Experimentally Probing the Shape of Extra Dimensions
In brane world scenarios in which only gravity can propagate in the extra
dimensions, effects on the gravitational force may be experimentally testable
if there are two or three large extra dimensions. The strength of the force at
distances smaller than the compactification radius will be sensitive to the
volume of the extra dimensions, but the determination of the shape requires
knowing the gravitational potential at intermediate scales. We determine the
dependence of the potential vs. distance as a function of both the relative
size of the extra dimensions and the possible angle between the extra
dimensional unit vectors, and show that high precision measurements of the
gravitational force will allow the determination of the shape of the extra
dimensions.Comment: Much more pedagogical version. Version to be published in the

A Calibrated Measurement of the Near-IR Continuum Sky Brightness Using Magellan/FIRE
We characterize the near-IR sky background from 308 observations with the
FIRE spectrograph at Magellan. A subset of 105 observations selected to
minimize lunar and thermal effects gives a continuous, median spectrum from
0.83 to 2.5 microns which we present in electronic form. The data are used to
characterize the broadband continuum emission between atmospheric OH features
and correlate its properties with observing conditions such as lunar angle and
time of night. We find that the moon contributes significantly to the
inter-line continuum in the Y and J bands whereas the observed H band continuum
is dominated by the blended Lorentzian wings of multiple OH line profiles even
at R=6000. Lunar effects may be mitigated in Y and J through careful scheduling
of observations, but the most ambitious near-IR programs will benefit from
allocation during dark observing time if those observations are not limited by
read noise. In Y and J our measured continuum exceeds space-based average
estimates of the Zodiacal light, but it is not readily identified with known
terrestrial foregrounds. If further measurements confirm such a fundamental
background, it would impact requirements for OH-suppressed instruments
operating in this regime.Comment: 25 pages, 11 figures, accepted to PAS
Beyond the RCT: Integrating Rigor and Relevance to Evaluate the Outcomes of Domestic Violence Programs
Programs for domestic violence (DV) victims and their families have grown exponentially over the last four decades. The evidence demonstrating the extent of their effectiveness, however, often has been criticized as stemming from studies lacking scientific rigor. A core reason for this critique is the widespread belief that credible evidence can derive only from research grounded in randomized control trials (RCTs). Although the RCT method has its strengths, we argue that it is rarely an optimal—or even a possible—approach for evaluating multifaceted DV programs. This article reviews the reasons that RCT is a poor fit for such programs and argues that a more inclusive conceptualization of credible evidence is critical to expanding our knowledge base about how DV programs affect survivors’ safety and well-being
Has Foreign Entry Made Domestic Banks More Efficient?
Has foreign entry indeed made domestic banks more efficient? Unite's and Sullivan's study, based on a sample of 16 expanded commercial banks (ECBs) and general macroeconomic data for the Philippines for the period 1990-1998, on the whole, supports the view of a general weakening of relationship-style banking brought about by the liberalization of foreign presence in the Philippine banking sector. This has consequences, of course, to the practices in the domestic banking industry.
