- The differential cross sections and vector analyzing powers for nd elastic scattering at E-n=248 MeV were measured for 10 degrees-180 degrees in the center-of-mass (c.m.) system. To cover the wide angular range, the experiments were performed separately by using two different setups for forward and backward angles. The data are compared with theoretical results based on Faddeev calculations with realistic nucleon-nucleon (NN) forces such as AV18, CD Bonn, and Nijmegen I and II, and their combinations with the three-nucleon forces (3NFs), such as Tucson-Melbourne 99 (TM99), Urbana IX, and the coupled-channel potential with Delta-isobar excitation. Large discrepancies are found between the experimental cross sections and theory with only 2N forces for theta(c.m.)>90 degrees. The inclusion of 3NFs brings the theoretical cross sections closer to the data but only partially explains this discrepancy. For the analyzing power, no significant improvement is found when 3NFs are included. Relativistic corrections are shown to be small for both the cross sections and the analyzing powers at this energy. For the cross sections, these effects are mostly seen in the very backward angles. Compared with the pd cross section data, quite significant differences are observed at all scattering angles that cannot be explained only by the Coulomb interaction, which is usually significant at small angles.

- BACKGROUND:Depressive symptoms are risk factors for poor outcomes and are positively associated with disease severity in patients with heart failure (HF). However, little is known about this association in the Japanese population. Therefore, we evaluated the prevalence of depressive symptoms and whether depressive symptoms predicted hospitalization for HF and death independent of disease severity and other factors in HF patients.METHODS AND RESULTS:A 2-year prospective cohort study was conducted on 115 outpatients with HF (73.9% males; mean age 64.7 years) in Tokyo. Of these, 27 patients (23.5%) were classified as having depressive symptoms (Center for Epidemiologic Studies Depression Scale score >or=16). Patients with depressive symptoms had higher rates of 2-year cardiac death or HF hospitalization (34.0% vs. 10.3%; P < .01), HF hospitalization (27.4% vs. 9.2%; P = .01), and all-cause death (27.4% vs. 7.2%; P < .01). Multivariate Cox regression analyses indicated that depressive symptoms were predictors of cardiac death or HF hospitalization (hazard ratio [HR], 3.29; P = .02), HF hospitalization (HR, 3.36; P = .04), and all-cause death (HR, 5.52; P = .01), independent of age and brain natriuretic peptide.CONCLUSIONS:Depressive symptoms were common and independent predictors of poor outcomes in Japanese patients with HF.
