We study the Magnus representation for homology cylinders as a generalization of the Gassner representation for string links defined by Le Dimet [12] and Kirk-Livingston-Wang [11]. As an application, we give some factorization formulas of higher-order degree invariants defined by Harvey in [9], [10] for closed three dimensional manifolds obtained from homology cylinders.

We define and study the Magnus representation for homology cylinders generalizing the work of Kirk, Livingston and Wang [KLW] which treats the case of string links. Using this, we give a factorization formula of Alexander polynomials for three dimensional manifolds obtained by closing homology cylinders. We also show a relationship between the Gassner representation for string links and the Mag...

Soils in ice-free areas of Livingston Island have been forming since the last deglaciation in a maritime warmer climate that is more humid than in interior Antarctica. A soil survey was carried out on Byers and Hurd peninsulas to characterize the soils and investigate the processes. Soils were sampled on two different substrates, mudstones and volcanic rocks in Byers Peninsula

To the present generation of doctors the name of Jonathan Hutchinson is associated with certain signs of syphilis, but there was "hardly any branch of medicine to which he did not make any contribution. For more than 20 years he was surgeon to London Hospital, and he was also on the staff of hospitals for chest, skin and eye diseases. It was an extraordinarily prolific period during which he ma...

T he weeks before and after the 2015 Boston Marathon were busy times for Jonathan Scheiman. “I was riding around Boston five hours a day picking up s--in a Zipcar and putting it on dry ice on the back seat,” he says. The fecal cargo came from 20 marathon runners. Scheiman and his colleagues at Harvard University brought the samples back to their lab and sequenced the DNA in the feces to identif...

The nematode communities of Antarctica are considered simple. The few species present are well adapted to the harsh conditions and often endemic to Antarctica. Knowledge of Antarctic terrestrial ecosystems is increasing rapidly, but nematode communities remain to be explored in large parts of Antarctica. In soil samples collected at Byers Peninsula (Antarctic Specially Protected Area No. 126), ...
