Ascites is the accumulation of fluid (usually serous fluid which is a pale yellow and clear fluid) that accumulates in the abdominal (peritoneal) cavity. The abdominal cavity is located below the chest cavity, separated from it by the diaphragm.

The sign of a real number, also called sgn or signum, is for a negative number (i.e., one with a minus sign ), 0 for the number zero, or for a positive number (i.e., one with a plus sign ). where is the Heaviside step function. The sign function is implemented in the Wolfram Language for real as Sign[x]. For nonzero complex numbers, Sign[z] returns , where is the complex modulus of . can also be interpreted as an unspecified point on the unit circle in the complex plane (Rich and Jeffrey 1996).
