This study examined underlying similarities between the Personal Authority in the Family System Questionnaire (PAFS; Bray, Williamson, & Malone, 1984a) and the Differentiation of Self Inventory (DSI; Skowron & Friedlander, 1998). Generalized least-squares factor analysis yielded two related factors, Self Regulation and Interdependent Relating, accounting for 60% of the variance in the solution....

In contrast to the dozens of proteins involved in ubiquitination pathways, relatively few proteins control SUMO modification. Generating specificity and diversity in pathway outcomes may therefore rely on post-translational modification of pathway components and/or substrates. A new paper in The EMBO Journal identifies one such modification event, the acetylation of Ubc9, as a key regulatory st...

Given any positive integer $n,$ let $A(n)$ denote the height of $n^{\text{th}}$ cyclotomic polynomial, that is its maximum coefficient in absolute value. It well known unbounded. We conjecture every natural number can arise as value and prove this assuming for pair consecutive primes $p$ $p'$ with $p\ge 127$ we have $p'-p<\sqrt{p}+1.$ also occurs some polynomial show true if Andrica's always $\...
