THE SPACE OF FINITELY GENERATED RINGS [PDF]
International Journal of Algebra and Computation, 2009 The space of marked commutative rings on n given generators is a compact metrizable space. We compute the Cantor–Bendixson rank of any member of this space. For instance, the Cantor–Bendixson rank of the free commutative ring on n generators is ωn, where ω is the smallest infinite ordinal.

Constructions and Enumerations of Self-Dual and LCD Double Circulant Codes over a Local Ring
MathematicsThe construction of self-dual and linear complementary dual (LCD) codes over finite rings, particularly over semi-local and local structures, is an active area of research due to their algebraic richness and applications in communications and ...

The Equivalence Problem for Finite Rings
Journal of Symbolic Computation, 1993 The equivalence problem (e.p.) for a ring is the problem of determining when two ring terms define the same function on the ring. Whereas \textit{H. B. Hunt} and \textit{R. E. Stearns} have earlier proved [ibid. 10, 411-436 (1990; Zbl 0724.68050)] for a finite ring \(R\) that: \(R\) is nilpotent implies the e.p.

Rings with a finite set of nonnilpotents
International Journal of Mathematics and Mathematical Sciences, 1979 Let R be a ring and let N denote the set of nilpotent elements of R. Let n be a nonnegative integer. The ring R is called a θn-ring if the number of elements in R which are not in N is at most n. The following theorem is proved: If R is a θn-ring, then R

CoRR, 2021 A (control) network over a finite ring is proposed. Using semi-tensor product (STP) of matrices, a set of algebraic equations are provided to verify whether a finite set with two binary operators is a ring. It is then shown that the STP-based technique developed for logical (control) networks are applicable to (control) networks over finite rings.

Optimizing photoexcitation conditions for time‐resolved X‐ray solution scattering experiments
FEBS Open Bio, EarlyView.Time‐resolved X‐ray solution scattering (TR‐XSS) is a powerful technique to visualize how proteins change their structure in real time after light activation. Selecting the right laser photoexcitation conditions—fluence, excitation geometry, and sample refresh rate—is critical to maximize the experimental signal while avoiding unwanted side effects ...

Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective Treatment of disorders of consciousness (DoC) remains a major clinical challenge, and noninvasive, targeted modulation of deep brain structures has emerged as a promising therapeutic strategy. We aimed to evaluate the feasibility/safety and preliminary effects of thalamic temporal interference stimulation (TIS) targeting centromedian‐
