We give a simple polynomial-time algorithm to exactly count the number of Euler Tours (ETs) of any Eulerian generalized series-parallel graph, and show how to adapt this algorithm to exactly sample a random ET of the given generalized series-parallel graph. Note that the class of generalized seriesparallel graphs includes all outerplanar graphs. We can perform the counting in time O(m∆), where ...

The initial benthic degradation of senescent Zostera marina leaves was studied in controlled flowthrough microcosm chambers for 33 d. Sediment chambers without added eelgrass leaves served as control chambers. The inflowing artificial seawater and ouflowing seawater were analyzed for dissolved organic carbon and nitrogen (DOC and DON), total acid-hydrolyzable amino acids (THAA), dissolved free ...

The Planned Parenthood Committee of Phoenix was established in 1942 to expand Arizona women's access to family planning [2] resources. The Planned Parenthood Committee of Phoenix was formed through the merging of The Mother's Health Clinic in Phoenix, Arizona, with the national Planned Parenthood Federation of America. The clinic was primarily based within the Phoenix Memorial Hospital campus b...

Isozyme characters, exclusive of allozymes (alleles), are potentially useful in phylogenetic investigations. Such data have been derived from the multilocus L-lactate dehydrogenase (LDH) enzyme system. Among non-avian reptiles, the classes of potential characters include (1) and number of loci encoding LDH, (2) heterotramer patterns, (3) tissue-specific patterns of gene expression, (4) tissue-s...

The findings ofa cholera epidemic in Krian district is reported. There were 77 cases and 92 carriers in the epidemic. Although the three main ethnic groups of Ma lays , Chinese and Indians were involved in the epidemic, the Malays constituted majority ofthe cases and carriers. The overall infection rate and case attack rate was higher among the younger population. The case: carrier ratio was al...

On June 20, 1978, Wolfgang BARGMANN, Professor emeritus of Kiel University and Chairman of the Department of Anatomy from 1946 to 1974, died at the age of seventy-two from cerebral hemorrhage. His name was well known to anatomists and biologists worldwide, not only for his outstanding accomplishments in the field of neurosecretion but also as the editor of Cell and Tissue Research (formerly Zei...

It is likely that the best-known paper on twins, at least in the English language, is " Primary biases in twin studies ". Although published as a review, it was more nearly a monograph and presented the most thorough discussion, then or now, of the potential effects of intrauterine phenomena on twin differences after birth. The paper called attention to peculiarities of development in twins: la...
