On regular trace languages

open access: yesTheoretical Computer Science, 1987
Let A be a finite alphabet and let r be a symmetrical relation on A. Let us consider the free partially commutative monoid M(A,r) generated by A with respect to r (i.e., the quotient of A * by the congruence relation generated by (ab,ba) for all (a,b) in r).

A geometric approach to the Yang-Mills mass gap

open access: yesJournal of High Energy Physics, 2023
I provide a new idea based on geometric analysis to obtain a positive mass gap in pure non-abelian renormalizable Yang-Mills theory. The orbit space, that is the space of connections of Yang-Mills theory modulo gauge transformations, is equipped with a ...

Phase Field Failure Modeling: Brittle‐Ductile Dual‐Phase Microstructures under Compressive Loading

open access: yesAdvanced Engineering Materials, EarlyView.
The approach by Amor and the approach by Miehe and Zhang for asymmetric damage behavior in the phase field method for fracture are compared regarding their fitness for microcrack‐based failure modeling. The comparison is performed for the case of a dual‐phase microstructure with a brittle and a ductile constituent.

Regularized Stress Tensor of Vector Fields in de Sitter Space

open access: yesUniverse
We study the Stueckelberg field in de Sitter space, which is a massive vector field with the gauge fixing (GF) term 12ζ(Aμ;μ)2. We obtain the vacuum stress tensor, which consists of the transverse, longitudinal, temporal, and GF parts, and each contains ...

Exact finite volume expectation values of Ψ ¯ Ψ $$ \overline{\varPsi}\varPsi $$ in the massive Thirring model from light-cone lattice correlators

open access: yesJournal of High Energy Physics, 2018
In this paper, using the light-cone lattice regularization, we compute the finite volume expectation values of the composite operator Ψ ¯ Ψ $$ \overline{\varPsi}\varPsi $$ between pure fermion states in the Massive Thirring Model.

Microfabricated Anisotropic Myobundles for the Scalable Production of Cardiac Tissue Grafts

open access: yesAdvanced Functional Materials, EarlyView.
Controlling the anisotropy of cardiac tissue remains an outstanding challenge in the field of cardiac tissue engineering. Here, we introduce an approach to generate anisotropic cardiac myobundles using cell‐adhesive, synthetic, electrospun fibers and stem cell‐derived cardiac fibroblasts.

Stable Approximations of a Minimal Surface Problem with Variational Inequalities

open access: yesAbstract and Applied Analysis, 1997
In this paper we develop a new approach for the stable approximation of a minimal surface problem associated with a relaxed Dirichlet problem in the space BV(Ω) of functions of bounded variation.

Notes on spinning operators in fermionic CFT

open access: yesJournal of High Energy Physics, 2017
The Gross-Neveu model defines a unitary CFT of interacting fermions in 2 < d < 4 which has perturbative descriptions in the 1/N expansion and in the epsilon-expansion near two and four dimensions.

Weaving Intelligence: Thermally Drawn Multimaterial Fibers Toward AI‐Enabled Smart Textiles

open access: yesAdvanced Materials, EarlyView.
Thermally drawn multimaterial fibers are rapidly advancing as intelligent structural units for next‐generation smart textiles. Integrating multimaterial architectures with neuromorphic and spiking‐neural‐network principles enables fabrics that can sense, compute, and adapt autonomously.
