    Notes: The photoelectron spectra of Co−n (3≤n≤70) were measured at the photon energy of 4.025 eV by use of a XeCl excimer laser. For Co−n with n=3, 4, and 6, the geometric and electronic structures were obtained from the spectra in comparison with the calculated spectra by the spin-polarized DV-Xα method. The spectra observed are reproduced reasonably well by the calculation with postulating the most probable geometrical structures. It is revealed that the 3d band with the majority spin is separated by 1.0–2.8 eV from that with the minority spin; the former is completely filled while the latter is partly filled and extends above Fermi level. The magnetic moments and the average exchange energies of these cluster anions were estimated. For Co−n with n≥7, the observed electron affinity depends linearly on the reciprocal of the cluster radius and approach the work function of a cobalt metal, as n increases. Below n=6, the electron affinity deviates from the linear dependence. This finding indicates that a size-dependent transition in the electronic structure occurs at n(approximately-equal-to)7. The spherical conducting drop model suggests the presence of mobile electrons in Co−n with n≥7. © 1995 American Institute of Physics.

    Notes: Background. Systemic lupus erythematosus (SLE) is designated by the Japanese government as one of the intractable diseases and all patients, who suffer from these diseases, are registered to get financial aid for treatment. Using newly registered SLE patients, a case-control study was conducted to evaluate potential risk factors. Methods. Two-hundred and eighty-two women SLE patients, newly registered to receive financial aid for treatment, and 292 randomly selected health examination participants at public health centers (controls) were surveyed from April 1988 through March 1990. By means of a self-administered questionnaire, data concerning demographic variables, smoking and drinking habits, past medical and reproductive history, and family history were collected. Results. Based on unconditional logistic regression analysis, the risk of SLE was significantly increased for current smokers (age-adjusted odds ratio (OR) = 2.31, 95% confidence interval (CI) (1.34–3.97). Alcohol and milk intake were inversely associated with risk. Family histories of asthma and collagen diseases, including SLE, were associated with significantly elevated risk of SLE (OR = 2.07, 95% ci 1.14–3.77; OR = 5.20, 95% CI 1.08–24.95, respectively). Regarding reproductive function, women with menarche at age 15 or later had significantly higher risk than those, who started menstruating before age 12 (OR = 3.82, 95% CI 1.66–8.81 for menarche at 〉 15 years and OR = 2.90, 95% a 1.14–7.39 for menarche at 〈inlineGraphic alt="geqslant R: gt-or-equal, slanted" extraInfo="nonStandardEntity" href="urn:x-wiley:00119059:IJD333:ges" location="ges.gif"/〉 16y). Conclusions. Our study suggests several risk factors, including smoking, family history, and reproductive history that may increase the risk of SLE.
