In math mode a tilde diacritic can be written as, e.g., \tilde{x}. For a wider tilde \widetilde can be used. The \sim command produce a tilde-like binary relation symbol that is often used in mathematical expressions, and the double-tilde â is obtained with \approx. The url package also supports entering tildes directly, e.g., \url{http://server/~name}.
Cerebral palsy (CP) is a broad term used to describe a group of chronic palsies -- disorders that impair control of movement due to damage to the developing brain.CP usually develops by age 2 or 3 and is a nonprogressive brain disorder, meaning the brain damage does not continue to worsen throughout life.erebral palsy (CP) is a broad term used to describe a group of chronic palsies -- disorders that impair control of movement due to damage to the developing brain.
The cerebrum makes up the largest part of the brain. Cerebral palsy is a non-progressive neurological disorder that affects body movement and muscle coordination.lthough the gray matter processes the information in the brain, the white matter transmits the signals to the rest of the body. Some cerebral palsy occurs due to damage to the white matter, a condition known as periventricular leukomalacia--PVL. The damage in PVL looks like tiny holes in the white matter.
