The derived-discrete algebras over the real numbers [PDF]

arXiv, 2020
We classify derived-discrete algebras over the real numbers up to Morita equivalence, using the classification of complex derived-discrete algebras in [{\sc D. Vossieck}, {\em The algebras with discrete derived category}, J. Algebra {\bf 243} (2001), 168--176].

An integrated scheduling and control scheme with two economic layers for demand side management of chemical processes

AIChE Journal, EarlyView.
Abstract Integrated dynamic scheduling (IDS) and economic nonlinear model predictive control (eNMPC) enable economic operation of chemical plants subject to volatile energy prices. Herein, we combine the two concepts into an integrated two‐layer scheme. Therein, IDS performs “long‐horizon” scheduling on a day‐ahead (DA) market and eNMPC “short‐horizon”

Baxter Algebras, Stirling Numbers and Partitions [PDF]

J. Algebra Appl. 4 (2005), 153-164, 2004
Recent developments of Baxter algebras have lead to applications to combinatorics, number theory and mathematical physics. We relate Baxter algebras to Stirling numbers of the first kind and the second kind, partitions and multinomial coefficients. This allows us to apply congruences from number theory to obtain congruences in Baxter algebras.

Magnetic particle capture in high‐gradient magnetic separation: A theoretical and experimental study

AIChE Journal, EarlyView.
Abstract High‐gradient magnetic separation (HGMS) has traditionally been used in mineral processing, with many effective models developed for typically employed rod‐wire shaped matrices. However, its potential in bioprocessing, especially for high‐value products, introduces new demands on plant and matrix design. This study presents a multi‐scale model

Unified Theory of Local Quantum Many-Body Dynamics: Eigenoperator Thermalization Theorems

Physical Review X, 2023
Explaining quantum many-body dynamics is a long-held goal of physics. A rigorous operator algebraic theory of dynamics in locally interacting systems in any dimension is provided here in terms of time-dependent equilibrium (Gibbs) ensembles.

Normal ordering associated with λ-Stirling numbers inλ-Shift algebra [PDF]

arXiv, 2023
The Stirling numbers of the second kind are related to normal orderings in the Weyl algebra, while the unsigned Stirling numbers of the first kind are related to normal orderings in the shift algebra. Kim-Kim introduced a {\lambda}-analogue of the unsigned Stirling numbers of the first kind and that of the r-Stirling numbers of the first kind.

Electrified distillation with flash vapor circulation and thermal storage for dynamic electricity markets

AIChE Journal, EarlyView.
Abstract Distillation is widely used for separating liquid mixtures, but its high heating demand poses challenges for achieving net‐zero emissions. This study presents an innovative approach to electrifying distillation for load adaptability and flexible operation, aligning with dynamic electricity markets driven by renewables.

Analytic curves in algebraic varieties over number fields

, 2007
We establish algebraicity criteria for formal germs of curves in algebraic varieties over number fields and apply them to derive a rationality criterion for formal germs of functions, which extends the classical rationality theorems of Borel-Dwork and P\'
