Quantum Drinfeld Hecke Algebras

open access: yes, 2013
We consider finite groups acting on quantum (or skew) polynomial rings. Deformations of the semidirect product of the quantum polynomial ring with the acting group extend symplectic reflection algebras and graded Hecke algebras to the quantum setting ...

Rendezvous in Space: Tech Diplomacy and the Commercial Space Era—A Study of Rendezvous and Docking Technologies and Space Exploration Co‐Operation Since the Cold War

open access: yesGlobal Policy, EarlyView.
ABSTRACT On‐orbit rendezvous and docking constitute one of the most technically challenging activities in the history of space activities. As space endeavours mature to crewed missions, space rendezous and docking technologies (RDT) emerge as an area of technological innovation critical to advances in future crewed space exploration.

The Witt Ring of a Curve with Good Reduction over a Non-dyadic Local Field [PDF]

open access: yes, 2014
In this work, we present a generalization to varieties and sheaves of the fundamental ideal of the Witt ring of a field by defining a sheaf of fundamental ideals $\tilde{I}$ and a sheaf of Witt rings $\tilde{W}$ in the obvious way.

On the center of the ring of differential operators on a smooth variety over $\bZ/p^n\bZ$

open access: yes, 2011
We compute the center of the ring of PD differential operators on a smooth variety over $\bZ/p^n\bZ$ confirming a conjecture of Kaledin. More generally, given an associative algebra $A_0$ over $\bF_p$ and its flat deformation $A_n$ over $\bZ/p^{n+1}\bZ ...

A Structured Review of Research‐Informed Instructional Strategies to Support CPA Enabling Competencies in Future Accountants*

open access: yesAccounting Perspectives, Volume 24, Issue 1, Page 189-249, March 2025.
ABSTRACT CPA enabling competencies underpin the human skills and professional values that all future accountants should possess. Nevertheless, to date, the discourse is limited within the scholarship of teaching and learning on how to best inculcate these competencies in future accountants.

Semi-galois Categories II: An arithmetic analogue of Christol's theorem

open access: yes, 2018
In connection with our previous work on semi-galois categories, this paper proves an arithmetic analogue of Christol's theorem concerning an automata-theoretic characterization of when a formal power series over finite field is algebraic over the ...

Novel Bispecific Engagers Targeting the CεmX Domain of mIgE‐Expressing Cells

open access: yesAllergy, EarlyView.
We developed bispecific TCE & NKCE targeting the CεmX domain of mIgE to eliminate IgE‐producing cells. Both constructs demonstrated potent, specific, dose‐dependent cytotoxicity and selective immune activation in vitro. These results highlight their promise as off‐the‐shelf, potentially curative therapeutics for IgE‐associated allergic diseases ...

Witt rings as integral rings

open access: yesInventiones Mathematicae, 1987
Let F denote a field of characteristic not two, and W(F) the Witt ring of classes of nondegenerate symmetric bilinear forms over F. It has been known since the definition of W(F) [\textit{E. Witt}, J. Reine Angew. Math. 176, 31-44 (1936; Zbl 0015.05701)] that W(F) is an integral extension of \({\mathbb{Z}}\).

Universal deformation rings for the symmetric group S_4

open access: yes, 2008
Let k be an algebraically closed field of characteristic 2, and let W be the ring of infinite Witt vectors over k. Let S_4 denote the symmetric group on 4 letters.
