The Game of Life, also known simply as Life, is a cellular automaton devised by the British mathematician John Horton Conway in 1970. [1] It is a zero-player game, [2][3] meaning that its evolution is determined by its initial state, requiring no further input. One interacts with the Game of Life by creating an initial configuration and ...
Bioconcentration. In aquatic toxicology, bioconcentration is the accumulation of a water-borne chemical substance in an organism exposed to the water. [ 1][ 2] There are several ways in which to measure and assess bioaccumulation and bioconcentration. These include: octanol-water partition coefficients (K OW ), bioconcentration factors (BCF ...
High-temperature operating life (HTOL) is a reliability test applied to integrated circuits (ICs) to determine their intrinsic reliability. This test stresses the IC at an elevated temperature, high voltage and dynamic operation for a predefined period of time. The IC is usually monitored under stress and tested at intermediate intervals.
In developmental biology, pattern formation refers to the generation of complex organizations of cell fates in space and time. The role of genes in pattern formation is an aspect of morphogenesis, the creation of diverse anatomies from similar genes, now being explored in the science of evolutionary developmental biology or evo-devo.
A blue variant of the print sold for $94,062.50 in Los Angeles in 2022. [3] Escher became interested in how forms could fit together to create what Sarah Lawson calls "paradoxical patterns", as when the black geese in Day and Night emerge from the darkened spaces between the white geese that are flying in the opposite direction. [4]
Fish locomotion. Fish locomotion is the various types of animal locomotion used by fish, principally by swimming. This is achieved in different groups of fish by a variety of mechanisms of propulsion, most often by wave-like lateral flexions of the fish's body and tail in the water, and in various specialised fish by motions of the fins.
The Nova Constellatio coins are the first coins struck under the authority of The United States of America. [1] These pattern coins were struck in early 1783, and are known in three silver denominations (1,000-Units, 500-Units, 100-Units), and one copper denomination (5-Units). All known examples bear the legend "NOVA CONSTELLATIO" with the ...
