In a Letter to the Editor of mBio, Professor Ron Fouchier published a calculation (1) in which he finds a very low probability, P1, for a laboratory-acquired infection (LAI) for a single lab for a single year. Claiming numerous safety precautions in his biosafety level 3 (BSL3 ) laboratory, Fouchier calculates P1 1 10–7 per person per year, and since there are 10 workers with access to his labo...

In 1956, Fraisse, et al. reported subjects judged that lines were longer when voluntary attention was focused on the lines than when attention was distracted from the lines. In the many attempts to repeat these results, none has ascertained whether attention on reported line length was a phenomenal effect. In the present study, 46 subjects were shown as stimuli pairs of horizontal or vertical b...

3 " If we were not able or did not desire to look in any new direction, if we did not have a doubt or recognize ignorance, we would not get any new ideas. There would be nothing worth checking, because we would know what is true. So what we call scientific knowledge today is a body of statements of varying degrees of certainty. Some of them are most unsure; some of them are nearly sure; but non...

in ttie uecemuer issue or tne maian Medical Gazette, there are several points raised which I would like to discuss as briefly as possible:? (i) Note on Locomotor Ataxy (p. 4G9). It is absolutely certain that this disease occurs in typical form amongst natives of India. During the last seven years I have had a good many cases admitted to my wards at the General Hospital. On the other hand, I hav...

We study probability distributions of convergent random series of a special structure, called perpetuities. By giving a new argument, we prove that such distributions are of pure type: degenerate, absolutely continuous, or continuously singular. We further provide necessary and sufficient criteria for the finiteness of p-moments, p > 0 as well as exponential moments. In particular, a formula fo...

Abstract. An original approach to the inverse scattering for Jacobi matrices was recently suggested in [17]. The authors considered quite sophisticated spectral sets (including Cantor sets of positive Lebesgue measure), however they did not take into account the mass point spectrum. This paper follows similar lines for the continuous setting with an absolutely continuous spectrum on the half-ax...
