The long-term goals are to understand how variabilities in the large-scale atmospheric environment and the internal tropical cyclone structure influence tropical cyclone track and intensity characteristics and define how these influences differ between developing, mature, and decaying tropical cyclones. During the initial stages of tropical cyclone development, structure and track characteristi...

In tropical algebraic geometry, the solution sets of polynomial equations are piecewise-linear. We introduce the tropical variety of a polynomial ideal, and we identify it with a polyhedral subcomplex of the Gröbner fan. The tropical Grassmannian arises in this manner from the ideal of quadratic Plücker relations. It is shown to parametrize all tropical linear spaces. Lines in tropical projecti...

Tropical differential equations are introduced and an algorithm is designed which tests solvability of a system of tropical linear differential equations within the complexity polynomial in the size of the system and in its coefficients. Moreover, we show that there exists a minimal solution, and the algorithm constructs it (in case of solvability). This extends a similar complexity bound estab...

of Tropical Medicine in Bombay has made considerable progress. The scheme, though but recently announced in the public press, has been maturing for nearly three years?in fact, it was first proposed by Major W. Grlen Liston, c.i.e., I.M.S., in July 1911. In a few words the scheme is as follows:?(1) Development and expansion of the existing Bombay Bacteriological Laboratory at Parel; (2) building...

nature but some dealing with more particular topics in the history of German medicine and science during the period 1871 to 1914. Amongst them Seidler writes on the political status of the doctor, Goerke on the panel doctor, Winau on the doctor and disease in poetry, Querner on Roux, Murken on Bad Nauheim, Jusatz on tropical medicine, Eichberg on body culture, and Rosner on the reception ofWest...

made a complaint against the members of the Service that they have done little, or have not done enough, research work in medicine, especially in tropical disease. The present time appears to be appropriate for an attempt to record what the Service, through the agency of its members, has done, during the past two centuries, towards the improvement of administration; the advancement, and, indeed...

The transition from miasma to germ theory in the late nineteenth and early twentieth century has been widely documented in narratives about the discovery of microbes, the evidence of contamination, or the procedures for sterilizations. This was a radical change in the history of understanding disease, treating and preventing it, and that shift marked a new era in medicine. However, it is import...
