The idea of the triangle was proposed by John Kenneth Galbraith and developed by Sábato as a model of policy-making in science and technology. [1]: 302–303 The model is based on the concept that in order for a scientific-technological system to exist in practice it is necessary for three sectors to be strongly linked together over the long term: the State (which formulates and implements ...
Peto's paradox is the observation that, at the species level, the incidence of cancer does not appear to correlate with the number of cells in an organism. [1] For example, the incidence of cancer in humans is much higher than the incidence of cancer in whales, [2] despite whales having more cells than humans.
The matrix–vector multiplication can be done in () arithmetical operations where is the average number of nonzero elements in a row. The total complexity is thus O ( d m n ) {\displaystyle O(dmn)} , or O ( d n 2 ) {\displaystyle O(dn^{2})} if m = n {\displaystyle m=n} ; the Lanczos algorithm can be very fast for sparse matrices.
The Codman triangle. The Codman triangle (previously referred to as Codman's triangle) is the triangular area of new subperiosteal bone that is created when a lesion, often a tumor, raises the periosteum away from the bone. [1]
Lung cancer, also known as lung carcinoma, is a malignant tumor that begins in the lung. Lung cancer is caused by genetic damage to the DNA of cells in the airways, often caused by cigarette smoking or inhaling damaging chemicals. Damaged airway cells gain the ability to multiply unchecked, causing the growth of a tumor.
In 2004, a researcher at VECTOR died after accidentally pricking herself with a needle contaminated with the Ebola virus. [14] On 17 September 2019, a gas explosion occurred at Vector. [15] One worker suffered third-degree burns, and the blast blew out window panes. The lab has highly contagious forms of bird flu and strains of hepatitis. [16]
