IN BRIEF In this article, the authors discuss several innovative concepts UnitedHealth Group Research & Development is exploring to help patients manage their type 2 diabetes. The article focuses on ...efforts to use remote support programs and wearable technology to empower patients to take more active roles in managing their health and to foster more interactive patient-provider conversations. Additionally, the authors reflect on how such efforts could particularly benefit medically underserved communities. They offer observations from claims data about current health outcomes and costs in underserved areas.
Experiment E864 at the Brookhaven AGS accelerator uses a high sensitivity, large acceptance spectrometer, designed to search for strangelets and other novel forms of matter produced in high-energy ...heavy ion collisions.

The E864 experiment at the AGS is designed to carry out high sensitivity searches for a variety of possible new particles using relativistic heavy ion Au beams on Pb and Pt targets. In order to reach ...the desired sensitivities, a level-2 “late energy” trigger was built to select events in which a heavy particle is detected in a hadronic calorimeter with deposited energy and time-of-flight from the target exceeding preset values. The physics motivation for the trigger is discussed and and details of its hardware and software design are given. Performance results from recent E864 data taking runs are presented.

A large hadronic lead scintillating fiber calorimeter has been built and integrated into the AGS experiment E864 C. Pruneau et al., E864 Collaboration, Proc. 6th Internal. Conf. on Calorimetry in ...High Energy Physics, 1996, Frascati, Italy; F. Rotondo et al., E864 Collaboration, Proc. Quark Matter'96, Heidelberg, Germany, 20 May 1996 spectrometer to provide an independent measurement of the mass of particles produced in heavy ion collisions. The “spaghetti-type” calorimeter design and construction techniques are described in detail. Results from a prototype and the full implementation of the calorimeter are reported. The hadronic energy resolution of the calorimeter is found to be 6E/E = 0.035(± 0.005) + 0.344(± 0.008)/trE/GeV, in very good agreement with a FLUKA calculation. The hadronic time resolution is measured to be better than 400 ps. The combined calorimeter energy and time signals provide for a mass determination with good resolution. The mass resolution scales as
δm/m = 0.026 + 0.347/√E(GeV) for velocities
v/c < 0.98.
We report on measurements by the E864 experiment at the BNL-AGS of the yields of light nuclei in collisions of {sup 197}Au with beam momentum of 11.5A GeV/c on targets of {sup 208}Pb and {sup 197}Pt. ...The yields are reported for nuclei with baryon number A=1 up to A=7, and typically cover a rapidity range from y{sub c.m.} to y{sub c.m.}+1 and a transverse momentum range of approximately 0.1{<=}p{sub T}/A{<=}0.5 GeV/c. We calculate coalescence scale factors B{sub A} from which we extract model-dependent source dimensions and collective flow velocities. We also examine the dependences of the yields on baryon number, spin, and isospin of the produced nuclei. (c) 2000 The American Physical Society.
