On the classification of nonsimple graph C*-algebras [PDF]
, 2009 We prove that a graph C*-algebra with exactly one proper nontrivial ideal is classified up to stable isomorphism by its associated six-term exact sequence in K-theory.

Commuting Pauli Hamiltonians as maps between free modules [PDF]
, 2012 We study unfrustrated spin Hamiltonians that consist of commuting tensor products of Pauli matrices. Assuming translation-invariance, a family of Hamiltonians that belong to the same phase of matter is described by a map between modules over the ...

On tilted Giraud subcategories [PDF]
, 2015 Firstly we provide a technique to move torsion pairs in abelian categories via adjoint functors and in particular through Giraud subcategories. We apply this point in order to develop a correspondence between Giraud subcategories of an abelian category C

Angewandte Chemie, EarlyView.A synergistic strategy enables the construction of hierarchical zeolites with selective removal of ∼60% of channel‐located Al, revealing that Brønsted acid sites (BAS) at channel intersections exhibit a TOF of 516 h−1, 13 times higher than those within the channels.

An Axiomatic Setup for Algorithmic Homological Algebra and an Alternative Approach to Localization [PDF]
, 2011 In this paper we develop an axiomatic setup for algorithmic homological algebra of Abelian categories. This is done by exhibiting all existential quantifiers entering the definition of an Abelian category, which for the sake of computability need to be ...

A note on coherent orientations for exact Lagrangian cobordisms
, 2019 Let $L \subset \mathbb R \times J^1(M)$ be a spin, exact Lagrangian cobordism in the symplectization of the 1-jet space of a smooth manifold $M$. Assume that $L$ has cylindrical Legendrian ends $\Lambda_\pm \subset J^1(M)$.

Steady State Simulation of a Delayed Coker Unit [PDF]
, 2009 Delayed coking is a form of thermal cracking used for processing "bottom of barrel" residuum. Thermal cracking produces a wide range of hydrocarbons along with coke.

Advanced Materials, EarlyView.This review examines the critical role of neighboring active motifs in heterogeneous catalysts, emphasizing how their synergistic cooperativity can be rationally designed to modulate catalytic properties. The discussion centers on the modulation of electronic and geometric structures, categorizing the catalytic systems into metal‐acid (Brønsted/Lewis ...

Euler characteristic and Akashi series for Selmer groups over global function fields
, 2017 Let $A$ be an abelian variety defined over a global function field $F$ of positive characteristic $p$ and let $K/F$ be a $p$-adic Lie extension with Galois group $G$.
