Viva the worm ike yin and yang, good things usually come at a cost. If you live longer, then you give up reproductive fitness in return. The merits of this model—termed antagonistic pleiotropy—have been argued by evolutionary biologists for half a century. Some believe that the effort of reproduction is necessarily linked to deterioration characteristic of aging. have challenged the idea by unc...

Thiocyanate, a ubiquitous anion in the body, inhibits the concentration of iodide by the thyroid and the iodination of tyrosine in this tissue (1, 2). This pseudohalide is oxidized by thyroid tissue in viva (3-6). Sulfate is the major sulfur product. This report will describe a cytoplasmic particulate system derived from mammalian thyroid tissue that oxidizes thiocyanate ion in vitro to product...

The aim of this project is to implement the operations of Elliptic Curve Cryptography built over GF(2) represented with optimal normal basis in VIVA System. These operations include multiplication, inverse, point addition, point doubling and scalar multiplication. The target device is Xilinx 4062 embedded in the FAI board of HAL-15 hypercomputer. The synthesis results using VIVA and VHDL are co...
