(1) Let X be a real linear space and R1, R2 be finite sequences of elements of X. If lenR1 = lenR2, then ∑ (R1 +R2) = ∑ R1 + ∑ R2. (2) Let X be a real linear space and R1, R2, R3 be finite sequences of elements of X. If lenR1 = lenR2 and R3 = R1−R2, then ∑ R3 = ∑ R1− ∑ R2. (3) Let X be a real linear space, R1, R2 be finite sequences of elements of X, and a be an element of R. If R2 = aR1, then ...
OBJECTIVES The aim of this study was to assess the impact of oral water and intravenous furosemide challenges on blood oxygenation level-dependent magnetic resonance imaging measurements in the kidney and to examine the contribution of R2 (=1/T2) to changes in R2* (=1/T2*). MATERIALS AND METHODS This Health Insurance Portability and Accountability Act-compliant study had institutional review ...
A bstract We study gravitational collapse for the Starobinsky R 2 model, a particular example of an f ( r ) theory, in spherically symmetric spacetime. add massless scalar field as matter content to work Einstein frame, where additional arises due conformal transformation. As general relativity, depending on initial data, we found that gravity and physical can collapse, forming black hole, whic...
