An easy proof of Jensen's theorem on the uniqueness of infinity harmonic functions
We present a new, easy, and elementary proof of Jensen's Theorem on the
uniqueness of infinity harmonic functions. The idea is to pass to a finite
difference equation by taking maximums and minimums over small balls.Comment: 4 pages; comments added, proof simplifie

Distributions and intercorrelations of 100 variables selected from physiological, personal history, and psychological measures of 1963 evaluation in Pensacola thousand aviator stud
Ray-based calculations of backscatter in laser fusion targets
A 1D, steady-state model for Brillouin and Raman backscatter from an
inhomogeneous plasma is presented. The daughter plasma waves are treated in the
strong damping limit, and have amplitudes given by the (linear) kinetic
response to the ponderomotive drive. Pump depletion, inverse-bremsstrahlung
damping, bremsstrahlung emission, Thomson scattering off density fluctuations,
and whole-beam focusing are included. The numerical code DEPLETE, which
implements this model, is described. The model is compared with traditional
linear gain calculations, as well as "plane-wave" simulations with the paraxial
propagation code pF3D. Comparisons with Brillouin-scattering experiments at the
OMEGA Laser Facility [T. R. Boehly et al., Opt. Commun. 133, p. 495 (1997)]
show that laser speckles greatly enhance the reflectivity over the DEPLETE
results. An approximate upper bound on this enhancement, motivated by phase
conjugation, is given by doubling the DEPLETE coupling coefficient. Analysis
with DEPLETE of an ignition design for the National Ignition Facility (NIF) [J.
A. Paisner, E. M. Campbell, and W. J. Hogan, Fusion Technol. 26, p. 755
(1994)], with a peak radiation temperature of 285 eV, shows encouragingly low
reflectivity. Re-absorption of Raman light is seen to be significant in this
design.Comment: 16 pages, 19 figure
A Cluster Randomized Trial of Adding Peer Specialists To Intensive Case Management Teams in the Veterans Health Administration
Use of Peer Specialists (PSs)—individuals with serious mental illness who use their experiences to help others with serious mental illness—is increasing. However, their impact on patient outcomes has not been demonstrated definitively. This cluster randomized, controlled trial within the Veterans Health Administration compared patients served by three intensive case management teams that each deployed two PSs for one year, to the patients of three similar teams without PSs (Usual Care). All patients (PS group=149, Usual Care=133) had substantial psychiatric inpatient histories and a primary Axis 1 psychiatric disorder. Before and after the year PSs worked, patients were surveyed on their recovery, quality of life, activation (health self-management efficacy), interpersonal relations, and symptoms. Patients in the PS group improved significantly more (z=2.00, df=1, p=0.05) than those receiving Usual Care on activation. There were no other significant differences. PSs helped patients become more active in treatment, which can promote recovery
