As the third director of the Carnegie Institution of Washington?s Department of Embryology, George Washington Corner [5] made a number of contributions to the life sciences as well as to administration. Corner was born on 12 December 1889 in Baltimore, Maryland, near the newly established Johns Hopkins University [6]. Although Corner was not exposed to science much in school at a young age, he ...

There is high confidence that climate change has increased the probability of concurrent temperature-precipitation extremes, changed their spatial-temporal variations and affected relationships between drivers such natural hazards. However, extent changes been less investigated in Australia. Daily data spanning period 1889-2019 (131 years) were extracted from SILO gridded dataset at 700 grid ce...

Cymindis (Iscariotes) kalabi sp. n. is described from the Halastandarya River basin, Kunlun Mt. Range, Xinjiang-Uygur Autonomous Region of China. New species similar to C. semenowi V.E. Jakovlev, 1889, jakowewi Semenov, 1889 and hyaloptera 1891 but differing all these taxa in shape head pronotum, structure male genitalia.

This paper gives local stability conditions for convergence of the price dynamics in a cobweb model with rationally heterogeneous expectations, generalizing the example of Brock and Hommes (1997). When agents choose between rational, naive, and adaptive beliefs, the steady state may be locally asymptotically stable if the adaptive predictor places enough weight on past prices and is costless. I...

The isolation of insulin by Banting and Best in 1921 and its rapid commercial exploitation revolutionized the treatment of diabetes. The story, frequently told as a romance of medicine, is that a young orthopaedic surgeon, Frederick Banting, went to the local Professor of Physiology, J J R Macleod, asking for facilities to try to isolate the internal secretion of the pancreas. Macleod was scept...

Diplommatinidae is a family of terrestrial caenogastropod snails that shows extensive species diversity and endemic radiation within the Palau (Belau) Islands. In this paper, we revised the taxonomy of Palauan endemic diplommatinids based on the comparative morphology of shell, operculum, radula, and genitalia. Although the generic classification of Palauan diplommatinids has been confusing, th...
