Transformation matrixIn linear algebra, linear transformations can be represented by matrices. If is a linear transformation mapping to and is a column vector with entries, then for some matrix , called the transformation matrix of . Note that has rows and columns, whereas the transformation is from to . There are alternative expressions of transformation matrices involving row vectors that are preferred by some authors. Matrices allow arbitrary linear transformations to be displayed in a consistent format, suitable for computation.
Growth accountingGrowth accounting is a procedure used in economics to measure the contribution of different factors to economic growth and to indirectly compute the rate of technological progress, measured as a residual, in an economy. Growth accounting decomposes the growth rate of an economy's total output into that which is due to increases in the contributing amount of the factors used—usually the increase in the amount of capital and labor—and that which cannot be accounted for by observable changes in factor utilization.
AdamAdam is the name given in Genesis 1-5 to the first human. Beyond its use as the name of the first man, adam is also used in the Bible as a pronoun, individually as "a human" and in a collective sense as "mankind". tells of God's creation of the world and its creatures, including adam, meaning humankind; in God forms "Adam", this time meaning a single male human, out of "the dust of the ground", places him in the Garden of Eden, and forms a woman, Eve, as his companion; in Adam and Eve eat the fruit of the tree of knowledge and God condemns Adam to labour on the earth for his food and to return to it on his death; deals with the birth of Adam's sons, and lists his descendants from Seth to Noah.
Substrate adhesion moleculesSubstrate adhesion molecules (SAMs) are proteins that attach cells to specific compounds in the extracellular matrix (a process known as cell adhesion). Some of the amino acids in the SAM bind to components of the extracellular matrix, while others bind to integrins on the surface of the cell. Integrin molecules are composed of two chains of amino acids, one of which is connected to the actin filaments in the cytoskeleton, while the other is connected to the SAMs.
Adam and EveAdam and Eve, according to the creation myth of the Abrahamic religions, were the first man and woman. They are central to the belief that humanity is in essence a single family, with everyone descended from a single pair of original ancestors. They also provide the basis for the doctrines of the fall of man and original sin that are important beliefs in Christianity, although not held in Judaism or Islam. In the Book of Genesis of the Hebrew Bible, chapters one through five, there are two creation narratives with two distinct perspectives.
