Interface Between Topological and Superconducting Qubits
We propose and analyze an interface between a topological qubit and a
superconducting flux qubit. In our scheme, the interaction between Majorana
fermions in a topological insulator is coherently controlled by a
superconducting phase that depends on the quantum state of the flux qubit. A
controlled phase gate, achieved by pulsing this interaction on and off, can
transfer quantum information between the topological qubit and the
superconducting qubit.Comment: 12 pages, 7 figures. V2: Final version as published in Phys. Rev.

Predictors of homelessness among families and single adults after exit from homelessness prevention and rapid re-housing programs: evidence from the Department of Veterans Affairs Supportive Services for Veteran Families Program
This article assesses the extent and predictors of homelessness among Veterans (both Veterans in families with children and single adults Veterans) exiting the Supportive Services for Veteran
Families (SSVF) program, which is
a nationwide
homelessness prevention and rapid re-housing
program geared primarily towards those experiencing crisis homelessness. Among
rapid re-housing participants,
16% and 26% of single adult Veterans experienced an episode of homelessness at one and two years post-SSVF exit; the comparable figures
at those
follow-up
times for Veterans in families were 9.4% and 15.5%, respectively. Relatively fewer single adult
Veterans and Veterans in families receiving homelessness prevention services experienced an
episode of homelessness at one
and two years post-SSVF exit. Veteran-level characteristics,
including age, gender, prior history of homelessness and recent engagement with VA healthcare
were generally more salient predictors of homelessness following SSVF exit than variables
measuring SSVF program factors, or
community-level housing market conditions.U.S. Department of Veterans Affairs, National Center on Homelessness Among Veteran
Does Practice-Based Teacher Preparation Increase Student Achievement? Early Evidence from the Boston Teacher Residency
The Boston Teacher Residency is an innovative practice-based preparation program in which candidates work alongside a mentor teacher for a year before becoming a teacher of record in Boston Public Schools. We find that BTR graduates are more racially diverse than other BPS novices, more likely to teach math and science, and more likely to remain teaching in the district through year five. Initially, BTR graduates for whom value-added performance data are available are no more effective at raising student test scores than other novice teachers in English language arts and less effective in math. The effectiveness of BTR graduates in math improves rapidly over time, however, such that by their fourth and fifth years they out-perform veteran teachers. Simulations of the program’s overall impact through retention and effectiveness suggest that it is likely to improve student achievement in the district only modestly over the long run.

Problems and Progress in Flare Fast Particle Diagnostics
Recent progress in the diagnosis of flare fast particles is critically
discussed with the main emphasis on high resolution Hard X-Ray (HXR) data from
RHESSI and coordinated data from other instruments. Spectacular new photon data
findings are highlighted as are advances in theoretical aspects of their use as
fast particle diagnostics, and some important comparisons made with
interplanetary particle data. More specifically the following topics are
addressed
(a) RHESSI data on HXR (electron) versus gamma-ray line (ion) source
locations.
(b) RHESSI hard X-ray source spatial structure in relation to theoretical
models and loop density structure.
(c) Energy budget of flare electrons and the Neupert effect.
(d) Spectral deconvolution methods including blind target testing and results
for RHESSI HXR spectra, including the reality and implications of dips inferred
in electron spectra
(e) The relation between flare in-situ and interplanetary particle data.Comment: 15 pages, 13 figures, submitted to Advances in Space Researc
