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.
In case of a two dimensional plane, two intersecting lines are said to be perpendicular lines if they intersect at right angles. In the figure, the lines $\overleftrightarrow{AB}$ and $\overleftrightarrow{CD}$ are perpendicular to each other intersecting at the point P. We can write.ase 3: Two lines are parallel and there is no intersection. Case 4: The two lines are not parallel, but there is no intersection. Such lines are called skew lines. If P(x, y, Z) is the intersecting point of the two line segments, it will be on both the line segments.
