She has a Master of Science in neuroscience from University of Copenhagen and a Ph.D. in philosophy from State University of New York at Buffalo. Drugs that interfere with the formation of new neural networks in the brain's main memory center can cause short-term memory loss. Short-term memory is the ability to store sensory information for relatively short times, ranging from a few minutes to a few days.
The vertical bar is used as a mathematical symbol in. 1  absolute value : , read the absolute value of x . 2  norms : , read the norm of x one, x two ; though Unicode also provides a special double vertical line symbol U+2016: âxâ. 3  Parallelism in geometry, where indicates that the line is parallel to the line.
Two lines that intersect and form right angles are called perpendicular lines. The symbol â¥ is used to denote perpendicular lines. In Figure , line l â¥ line m. Figure 2 Perpendicular lines. Two lines, both in the same plane, that never intersect are called parallel lines. Parallel lines remain the same distance apart at all times. The symbol // is used to denote parallel lines. In Figure 3, l // m. Figure 3 Parallel lines.
