Web1 dag geleden · Background: Sensory overresponsivity (SOR) has emerged as a potential endophenotype in obsessive-compulsive disorder (OCD), but few studies have examined SOR in relation to the major symptom dimensions of OCD and to symptoms across the full obsessive-compulsive (OC) symptom spectrum. Objective: This study had 2 main … Webrelations on [n]. (c)How many symmetric relations are there on [n]? For a symmetric relation we must have a j;i = a i;j for each i;j 2[n] (the adjacency matrix is equal to its own transpose). Once a i;j has been speci ed for i j, the remaining entries are determined. Hence there are 2n 2 n 2 +n = 21 2 n(n+1) symmetric relations on [n].
