Embedded minimal surfaces

The study of embedded minimal surfaces in \RR^3 is a classical problem, dating to the mid 1700's, and many people have made key contributions. We will survey a few recent advances, focusing on joint work with Tobias H. Colding of MIT and Courant, and taking the opportunity to focus on results that have not been highlighted elsewhere.Comment: To appear in proceedings of Madrid ICM200

Thyroid Hormone as a Method of Reducing Damage to Donor Hearts after Circulatory Arrest

There is a chronic lack of donor hearts to meet the need for heart transplant both in the US and worldwide. Further, the use of available hearts is limited by the short period between collection and implantation during which the heart can be safely preserved ex vivo. Using mid-thermic Langendorff machine perfusion, we have been able to preserve the metabolic function of a healthy heart for up to 8 hours, twice the limit for current static cold storage. We have also been able to preserve the metabolic function of a damaged DCD Heart collected 30 minutes after cardiac arrest for a period of 8 hours. We further investigated whether it was possible to improve the preservation of DCD heart using treatment with 10 μM Triiodothyronine to stimulate the tissue metabolism and we did find a reduction in damage markers in the treated DCD hearts as compared to the untreated group

Hyperbolic Structures on 3-manifolds, II: Surface groups and 3-manifolds which fiber over the circle

Geometrization theorem, fibered case: Every three-manifold that fibers over the circle admits a geometric decomposition. Double limit theorem: for any sequence of quasi-Fuchsian groups whose controlling pair of conformal structures tends toward a pair of projectively measured laminations that bind the surface, there is a convergent subsequence. This preprint also analyzes the quasi-isometric geometry of quasi-Fuchsian 3-manifolds. This eprint is based on a 1986 preprint, which was refereed and accepted for publication, but which I neglected to correct and return. The referee's corrections have now been incorporated, but it is largely the same as the 1986 version (which was a significant revision of a 1981 version).Comment: 32 pages, 6 figures, revision of 1986 preprin

On the Feeding Habits of \u3ci\u3ePhasganophora Capitata\u3c/i\u3e (Plecoptera: Perlidae)

Gut contents of 230 nymphs of Phasganophora Capitata (Pictet) from the Pigeon River, Otsego County, Michigan were analyzed in relation to season, current velocity, time of day, predator size and prey abundance. Diet changed seasonally, related in part to seasonal changes in prey abundance. The diet of large and small nymphs was similar except that small nymphs ate smaller individuals. At lower current velocities capitata fed primarily on mayflies whereas at higher current velocities they fed primarily on caddis and dipterans
