The support of top graded local cohomology modules [PDF]
, 2003 Let $R_0$ be any domain, let $R=R_0[U_1, ..., U_s]/I$, where $U_1, ..., U_s$ are indeterminates of some positive degrees, and $I\subset R_0[U_1, ..., U_s]$ is a homogeneous ideal. The main theorem in this paper is states that all the associated primes of

The Canadian Journal of Chemical Engineering, EarlyView.Abstract Remaining useful life (RUL) analysis of equipment prevents failures and assists in maintenance to address impending failures. To achieve this, the advancement of degradation can be measured through a determinant variable. This work presents a new methodology for estimating the number of remaining cycles (NRC), or RUL, of equipment in cyclic ...

The C*-algebra of an affine map on the 3-torus
, 2012 We study the C*-algebra of an affine map on a compact abelian group and give necessary and sufficient conditions for strong transitivity when the group is a torus.

ChemSusChem, Volume 18, Issue 6, March 15, 2025.A sustainable alternative to steam cracking, the molten‐salt‐mediated oxidative dehydrogenation (MM‐ODH) of ethane (C2H6) in Li2CO3‐Na2CO3‐K2CO3 (LNK) couples thermal cracking with melt‐mediated CO2 capture to realize commercially competitive C2H4 and CO yields. LNK composition strongly influences MM‐ODH process outcomes.
