Single production off neutrons bound in deuteron with linearly polarized photons.

The quasifree photon beam asymmetry, , has been measured at photon energies, , from 390 to 610 MeV, corresponding to center of mass energy from 1.271 to 1.424 GeV, for the first time.

Helicity-Dependent Cross Sections for the Photoproduction of π^{0} Pairs from Nucleons.

The double-polarization observable E and helicity-dependent cross sections σ_{1/2}, σ_{3/2} have been measured for the photoproduction of π^{0} pairs off quasifree protons and neutrons at the Mainz MAMI accelerator with the Crystal Ball/TAPS setup. A circularly polarized photon beam was produced by bremsstrahlung from longitudinally polarized electrons and impinged on a longitudinally polarized deuterated butanol target. The reaction products were detected with an almost 4π covering calorimeter.

Study of η and η' Photoproduction at MAMI.

The reactions γp→ηp and γp→η^{'}p are measured from their thresholds up to the center-of-mass energy W=1.96  GeV with the tagged-photon facilities at the Mainz Microtron, MAMI. Differential cross sections are obtained with unprecedented statistical accuracy, providing fine energy binning and full production-angle coverage.

Improving Treatment Adherence in Heart Failure.

Background: Despite improved treatment options, heart failure remains the third most common cause of death in Germany and the most common reason for hospitalization. The treatment recommendations contained in the relevant guidelines have been incompletely applied in practice. The goal of this systematic review is to study the efficacy of adherence-promoting interventions for patients with heart failure with respect to the taking of medications, the implementation of recommended lifestyle changes, and the improvement in clinical endpoints.

Measurements of double-polarized compton scattering asymmetries and extraction of the proton spin polarizabilities.

The spin polarizabilities of the nucleon describe how the spin of the nucleon responds to an incident polarized photon. The most model-independent way to extract the nucleon spin polarizabilities is through polarized Compton scattering. Double-polarized Compton scattering asymmetries on the proton were measured in the Δ(1232) region using circularly polarized incident photons and a transversely polarized proton target at the Mainz Microtron.

Measurement of the transverse target and beam-target asymmetries in η meson photoproduction at MAMI.

We present new data for the transverse target asymmetry T and the very first data for the beam-target asymmetry F in the γ[over →]p[over →]→ηp reaction up to a center-of-mass energy of W=1.9  GeV. The data were obtained with the Crystal-Ball/TAPS detector setup at the Glasgow tagged photon facility of the Mainz Microtron MAMI.

High-resolution spectrometer using combined dispersive and interferometric wavelength separation for raman and laser-induced breakdown spectroscopy (LIBS).

In this paper the concept of a compact high-resolution spectrometer based on the combination of dispersive and interferometric elements is presented. Dispersive elements are used to spectrally resolve the light in one direction with coarse resolution (Δλ < 0.5 nm), while perpendicular to that direction an etalon provides high spectral resolution (Δλ < 50 pm).

Measurement of the 1H(γ, p)π0 reaction using a novel nucleon spin polarimeter.

We report the first large-acceptance measurement of polarization transfer from a polarized photon beam to a recoiling nucleon. The measurement pioneers a novel polarimetry technique, which can be applied to many other nuclear and hadron physics experiments. The commissioning reaction of 1H(γ, p)π0 in the range 0.

Narrow structure in the excitation function of η photoproduction off the neutron.

The photoproduction of η mesons off nucleons bound in 2H and 3He has been measured in coincidence with recoil protons and recoil neutrons for incident photon energies from threshold up to 1.4 GeV. The experiments were performed at the Mainz MAMI accelerator, using the Glasgow tagged photon facility.

Chronic non-cancer pain: a siren for primary care--a report from the PRImary Care MultiEthnic Network (PRIME Net).

Introduction: Patients with chronic non-cancer pain (CNCP) are common and have a high degree of morbidity. Previous studies document clinician frustration and variability in CNCP management. We conducted this study to gather in-depth clinicians' views about factors that affect management of CNCP.

Beam-helicity asymmetries in double-pion photoproduction off the proton.

Beam-helicity asymmetries have been measured at the MAMI accelerator in Mainz in the three isospin channels gamma[over -->]p-->pi(+)pi(0)n, gamma[over -->]p-->pi(0)pi(0)p, and gamma[over -->]p-->pi(+)pi(-)p. The circularly polarized photons, produced from bremsstrahlung of longitudinally polarized electrons, were tagged with the Glasgow magnetic spectrometer. Charged pions and the decay photons of pi(0) mesons were detected in a 4pi electromagnetic calorimeter which combined the Crystal Ball detector with the TAPS detector.

Incoherent neutral pion photoproduction on 12C.

We present the first detailed measurement of incoherent photoproduction of neutral pions to a discrete state of a residual nucleus. The 12C(gamma,pi(0))(12)C*(4.4 MeV) reaction has been studied with the Glasgow photon tagger at MAMI employing a new technique which uses the large solid angle Crystal Ball detector both as a pi(0) spectrometer and to detect decay photons from the excited residual nucleus.

Integrating population health into a family medicine clerkship: 7 years of evolution.

A population health curriculum using methodologies from community-oriented primary care (COPC) was developed in 1994 as part of a required third-year family medicine clerkship at the University of New Mexico. The curriculum integrates population health/community medicine projects and problem-based tutorials into a community-based, ambulatory clinical experience. By combining a required population health experience with relevant clinical training, student careers have the opportunity to be influenced during the critical third year.

Vigilance and automobile accidents in patients with sleep apnea or narcolepsy.

Patients with obstructive sleep apnea or narcolepsy report difficulty remaining alert and attentive. To detect impaired vigilance, we designed Steer Clear, a computer program simulating a long and monotonous highway drive that presents 780 obstacles in 30 min. Sixty-two patients with sleep apnea hit a higher percentage of obstacles (4.
