Each PHP revenue code is associated with particular cost centers on the cost report. The revenue-to-cost-center crosswalk identifies the primary, secondary (if any), and tertiary (if any) cost centers that are associated with each PHP revenue code, and which are the source for the CCRs used in PHP ratesetting. The PHP portion of that OPPS crosswalk is shown in Table 52 below.
convex. adj. 1. curving or bulging outwards. 2. (General Physics) physics having one or two surfaces curved or ground in the shape of a section of the exterior of a sphere, paraboloid, ellipsoid, etc: a convex lens. 3. (Mathematics) maths (of a polygon) containing no interior angle greater than 180Â°.
Equivalently, a function is convex if its epigraph (the set of points on or above the graph of the function) is a convex set. Well-known examples of convex functions are the quadratic function and the exponential function for any real number x. Every real-valued linear transformation is convex but not strictly convex, since if f is linear, then This statement also holds if we replace convex by concave. 2  Every real-valued affine function, i.e., each function of the form, is simultaneously convex and concave.
