Reflections on Service to the Poor
James Cormack reflects on the Vincentian charism from his own experience. Vincentian service is a call from God’s love to return that love. It requires seeing Christ crucified in persons who are poor. It takes faith but also deepens faith. As Cormack sees them, the main qualities of the charism are compassion, courage, weakness, a commitment to smallness, and a change of heart. Weakness is necessary because we must recognize that we, too, need help and that the strength to serve comes from God. A commitment to smallness entails being satisfied with doing ordinary things; if we desire personal fulfillment too much, we risk ignoring the poor’s needs. A change of heart means not only loving but also being open to having love and service reciprocated. The charism requires people who can work without seeing the goals of their service fulfilled and who are consumed by the desire to serve
A search for the decay
We search for the rare flavor-changing neutral-current decay in a data sample of 82 fb collected with the {\sl BABAR}
detector at the PEP-II B-factory. Signal events are selected by examining the
properties of the system recoiling against either a reconstructed hadronic or
semileptonic charged-B decay. Using these two independent samples we obtain a
combined limit of
at the 90% confidence level. In addition, by selecting for pions rather than
kaons, we obtain a limit of using only the hadronic B reconstruction method.Comment: 7 pages, 8 postscript figures, submitted to Phys. Rev. Let
High-reflectivity broadband distributed Bragg reflector lattice matched to ZnTe
We report on the realization of a high quality distributed Bragg reflector
with both high and low refractive index layers lattice matched to ZnTe. Our
structure is grown by molecular beam epitaxy and is based on binary compounds
only. The high refractive index layer is made of ZnTe, while the low index
material is made of a short period triple superlattice containing MgSe, MgTe,
and ZnTe. The high refractive index step of Delta_n=0.5 in the structure
results in a broad stopband and the reflectivity coefficient exceeding 99% for
only 15 Bragg pairs.Comment: 4 pages, 3 figure
EuFeAs under high pressure: an antiferromagnetic bulk superconductor
We report the ac magnetic susceptibility and resistivity
measurements of EuFeAs under high pressure . By observing nearly
100% superconducting shielding and zero resistivity at = 28 kbar, we
establish that -induced superconductivity occurs at ~30 K in
EuFeAs. shows an anomalous nearly linear temperature dependence
from room temperature down to at the same . indicates that
an antiferromagnetic order of Eu moments with ~20 K persists
in the superconducting phase. The temperature dependence of the upper critical
field is also determined.Comment: To appear in J. Phys. Soc. Jpn., Vol. 78 No.
Improved measurement of CP asymmetries in B-0 ->(c(c)over-bar)K0((*)) decays
We present results on time-dependent CP asymmetries in neutral B decays to several CP eigenstates. The measurements use a data sample of about 227x10(6) Upsilon(4S)-> B (B) over bar decays collected by the BABAR detector at the PEP-II asymmetric-energy B Factory at SLAC. The amplitude of the CPasymmetry, sin2 beta in the standard model, is derived from decay-time distributions from events in which one neutral B meson is fully reconstructed in a final state containing a charmonium meson and the other B meson is determined to be either a B-0 or (0) from its decay products. We measure sin2 beta=0.722 +/- 0.040(stat)+/- 0.023(syst) in agreement with the standard model expectation

Splenic artery embolisation in the non-operative management of blunt splenic trauma in adults
Background: The purpose of this study was to evaluate the splenic salvage rate with angioembolisation in the non-operative management (NOM) of blunt splenic injury.
Methods: We conducted a retrospective analysis of patients presenting to our Level I trauma centre with computed tomography (CT)-confirmed splenic injury following blunt trauma and in whom angioembolisation was utilised in the algorithm of NOM. Data review included CT and angiography findings, embolisation technique and patient outcomes.
Results: Between January 2005 and April 2010, 60 patients with splenic injury following blunt trauma underwent NOM, which included splenic artery embolisation (SAE). All patients included in the study required a preadmission. CT scan was used to document the American Association for the Surgery of Trauma (AAST) grade of splenic injury. The average injury grade was 3.0. The non-operative splenic salvage rate following SAE was 96.7% with statistically similar salvage rates achieved for grades II to IV injuries. The quantity of haemoperitoneum and the presence of a splenic vascular injury did not significantly affect the splenic salvage rate. The overall complication rate was 27%, of which 15% were minor and 13% were major.
Conclusion: SAE is a safe and effective treatment strategy in the NOM of blunt splenic injury. The quantity of haemoperitoneum, the presence of vascular injury and embolisation technique did not significantly affect the splenic salvage rate
