Simulation modeling and preliminary analysis of TIMS data from the Carlin area and the northern Grapevine Mountains, Nevada
A theoretical radiance model was employed together with laboratory data on a suite of igneous rock to evaluate various algorithms for processing Thermal Infrared Multispectral Scanner (TIMS) data. Two aspects of the general problem were examined: extraction of emissivity information from the observed TIMS radiance data, and how to use emissivity data in a way that is geologically meaningful. The four algorithms were evaluated for appropriate band combinations of TIMS data acquired on both day and night overflights of the Tuscarora Mountains, including the Carlin gold deposit, in north-central Nevada. Analysis of a color composited PC decorrelated image (Bands 3, 4, 5--blue/green/red) of the Northern Grapevine Mountains, Nevada, area showed some useful correlation with the regional geology. The thermal infrared region provides fundamental spectral information that can be used to discriminate the major rock types occurring on the Earth's surface

Medi-Cal Expansion under the Affordable Care Act: Significant Increase in Coverage with Minimal Cost to the State
Since 2011, California has been taking steps towards expanding Medicaid under the Afordable Care Act (ACA) by implementing Low Income Health Programs (LIHPs) in most California counties. Under the "Bridge to Reform" Medicaid §1115 waiver, just over 500,000 California adults are currently enrolled in coverage in advance of ACA implementation using federal and county funds. he vast majority of these LIHP enrollees can become eligible for Medi-Cal coverage under the ACA beginning January 1, 2014, and the remainder will be eligible for subsidies through Covered California (the California Health Benefit Exchange).In early 2013, California legislators will consider bills to implement a key provision of the ACA that would expand Medi-Cal to low-income adults under age 65, including those without children living at home. Lawfully-present childless adults with income up to 138 percent of the Federal Poverty Level and parents with income between 106 percent and 138 percent of the Federal Poverty Level will be newly eligible. Some unenrolled children and parents who are already income-eligible for the program under existing eligibility rules could also enroll due to the minimum coverage requirement to obtain insurance created by the ACA, improved eligibility, enrollment and redetermination processes, and enhanced awareness of coverage options.In this report, we estimate the growth in Medi-Cal enrollment among both the newly and already eligible using the UC Berkeley-UCLA California Simulation of Insurance Markets (CalSIM) model. We discuss the broader impact of the Medi-Cal Expansion in terms of health outcomes, providers and the economy. We estimate the federal and state spending on increased Medi-Cal enrollment, along with the state tax revenues generated by new federal Medi-Cal spending and potential savings in other areas of the budget

Newly Insured Californians Would Fall by More than 1 Million Under the Affordable Care Act Without the Requirement to Purchase Insurance
Compares the estimated number and percentage of currently uninsured Californians who will be insured by 2019 under the Affordable Care Act with the individual mandate and without. Highlights the need for the mandate to ensure affordable coverage

Achieving Equity by Building a Bridge From Eligible to Enrolled
Calls for multilingual outreach and enrollment efforts to enable Californians of color and those with limited English proficiency to benefit from the Health Benefit Exchange. Recommends targeting high-need groups and strengthening data collection
In-Plane Behavior of Cold-Formed Steel-Framed Shear Wall Panels Sheathed with Fibre Cement Board
Shear wall panels are commonly used as lateral load resisting elements to provide stability of the cold-formed steel-framed houses in Australia against wind and earthquake actions. The effectiveness of their lateral resistance behavior is obtained usually by experimental testing although it can also be done by analytical modeling. This paper presents racking test results of steelframed wall panels with different aspect ratios sheathed with fibre cement board subjected to monotonic and cyclic loading protocol. Performance parameters of the wall panels are obtained from the experimentally observed load-deflection curves using various existing methods and evaluation method is proposed. The evaluation method considers various performance characteristics including ductility modification factor, residual displacement recovery and load levels satisfying ultimate and serviceability limit state conditions
The 6dF Galaxy Survey
The 6dF Galaxy Survey (6dFGS) is a spectroscopic survey of the entire
southern sky with , based on the 2MASS near infrared galaxy
catalog. It is conducted with the 6dF multi-fiber spectrograph attached to the
1.2-m UK Schmidt Telescope. The survey will produce redshifts for some 170,000
galaxies, and peculiar velocities for about 15,000 and is expected to be
complete by June 2005.Comment: 8 pages, 4 figures, IAU 8th Asian-Pacific Regional Mettin
A method of incorporating general relativity in electromagnetic particle-in-cell code
An algorithm is presented that incorporates the tensor form of Maxwell's
equations in a general relativistic electromagnetic particle-in-cell code. The
code simplifies to Schwartzschild space-time for a non-spinning central mass.
The particle advance routine uses a fourth-order Runge-Kutta algorithm to
integrate the four-velocity form of Lorentz force. The current density is
calculated using the curved space-time of the metric.Comment: 17 pages, 8 figure

PhoneSat In-flight Experience Results
Over the last decade, consumer technology has vastly improved its performances, become more affordable and reduced its size. Modern day smartphones offer capabilities that enable us to figure out where we are, which way we are pointing, observe the world around us, and store and transmit this information to wherever we want. These capabilities are remarkably similar to those required for multi-million dollar satellites. The PhoneSat project at NASA Ames Research Center is building a series of CubeSat-size spacecrafts using an off-the-shelf smartphone as its on-board computer with the goal of showing just how simple and cheap space can be. Since the PhoneSat project started, different suborbital and orbital flight activities have proven the viability of this revolutionary approach. In early 2013, the PhoneSat project launched the first triage of PhoneSats into LEO. In the five day orbital life time, the nano-satellites flew the first functioning smartphone-based satellites (using the Nexus One and Nexus S phones), the cheapest satellite (a total parts cost below $3,500) and one of the fastest on-board processors (CPU speed of 1GHz). In this paper, an overview of the PhoneSat project as well as a summary of the in-flight experimental results is presented
