Piecewise-linear pseudodiagrams
There are 2^n possible resolutions of a smooth pseudodiagram with n
precrossings. If we consider piecewise-linear (PL) pseudodiagrams and
resolutions that themselves are PL, certain resolutions of the pseudodiagram
may not exist in three-space. We investigate this situation and its impact on
the weighted resolution set of PL pseudodiagrams as well as introduce a concept
specific to PL pseudodiagrams, the forcing number. Our main result classifies
the PL shadows whose weighted resolution sets differ from the weighted
resolution set that would exist in the smooth case.Comment: 7 pages, 8 figures; V2 fixes a minor typo in both statement of Cor.

In lieu of an abstract, below is the essay\u27s first paragraph.
The torrent of the rain had fallen in wind-whipped sheets, each swollen droplet crashing on the street like so many shuttering crystals; and now, in the late afternoon, the flushed city streets be~an to steam as a cooling breeze followed in the wake of the summer squall. Above the indistinct bustle characteristic of the town could be heard the dull rumble of a gasoline-laden truck approaching a busy and congested intersection. No one, however, seemed to notice

Alcohol consumption is associated with increased all-cause mortality in Russian men and women: a cohort study based on the mortality of relatives
Objectives: To examine the relationships between frequency of alcohol consumption and of binge drinking and adult mortality in Russian men and women.Methods : Using modified indirect demographic techniques, a convenience cohort was constructed based on survey respondents? information about their close relatives. A random sample general population of the Russian Federation of 7172 respondents (response rate 61%) provided information on 10475 male and 3129 female relatives, including age, vital status and frequency of alcohol consumption and binge drinking. These relatives formed the cohort analysed in this report. The outcome measure was all-cause mortality after the age of 30 years.Findings: There was a strong linear relationship between frequency of drinking and of binge drinking and all-cause mortality in men; after controlling for smoking and calendar period of birth, the relative risk of death in daily drinkers compared to occasional drinkers was 1.52 (95% CI 1.33 ?1.75). Male binge drinkers had higher mortality than drinkers who did not binge, which persisted after adjustment for drinking frequency (adjusted RR 1.09 (1.00-1.19). In women, the increased mortality was confined to a small group of those who binged at least once a month (adjusted relative risk 2.68, 1.54-4.66). Conclusions: The results suggest a positive association between alcohol and mortality in Russia. There was no evidence for the protective effect of drinking seen in western populations. Alcohol appears to have contributed to the high long-term mortality rates in Russian men, but it is unlikely to be a major cause of female mortality.
