Semi-strongly irreducible shifts [PDF]

, 2003
If Z is the group of integers, A a finite alphabet and AZ the set of all functions c:Z→A, the equivalence between pre-injectivity and surjectivity of a local function holds for irreducible shifts of finite type of AZ (see [Pure Math. Appl.

Receptor‐Free Identification of Toxic Gases Enabled by Hygroscopic Aqueous Salt Films

Advanced Functional Materials, EarlyView.
Water as a gas sensor coating sounds impossible—until it stops evaporating. Here, hygroscopic salt solutions (LiCl, LiBr, H3PO4) form non‐drying aqueous films on CNT chemiresistors under ambient air. Gases partition into these liquid layers, sometimes transforming into water, and generate salt‐specific resistance fingerprints across a four‐channel ...

Equivariant Flow Equivalence of Shifts of Finite Type by Matrix Equivalence over Group Rings [PDF]

, 2005
Let G be a finite group. We classify G-equivariant flow equivalence of non-trivial irreducible shifts of finite type in terms of (i) elementary equivalence of matrices over ZG and (ii) the conjugacy class in ZG of the group of G-weights of cycles based ...

Dynamics of sofic shifts [PDF]

, 2022
In this paper, we provide a characterization for the subshifts of finite type (SFT) in terms of Cellular automata (CA). In addition, we prove that 1. The following are equivalent for a non-singleton subshift of finite type XF . a) XF is transitive and

Irradiation‐Induced Spin Bath Evolution and as‐Grown Hydrogen Defects in CVD Diamond Revealed by NV‐Based DEER Spectroscopy

Advanced Functional Materials, EarlyView.
Here, we provide the reader with the current state of the art in the fabrication of high‐T2‐coherence diamond, optimized through the use of double electron–electron resonance (DEER) spectroscopy. We reveal the main as well as yet unidentified spin defects, the reduction of which is essential for reducing the spin bath and fabricating materials for ...

A MATRIX FORMALISM FOR CONJUGACIES OF HIGHER-DIMENSIONAL SHIFTS OF FINITE TYPE [PDF]

, 2008
. We develop a natural matrix formalism for state splittings and amalgamations of higher-dimensional subshifts of finite type which extends the common notion of strong shift equivalence of Z +-matrices.

Shifts of finite type on locally finite groups

Ergodic Theory and Dynamical Systems
AbstractIn this work we prove that every shift of finite type (SFT), sofic shift, and strongly irreducible shift on locally finite groups has strong dynamical properties. These properties include that every sofic shift is an SFT, every SFT is strongly irreducible, every strongly irreducible shift is an SFT, every SFT is entropy minimal, and every SFT ...

Integrated Field‐Free SOT Domain‐Wall Synapses and MTJ Stochastic Neurons for Hardware Boltzmann Machines

Advanced Functional Materials, EarlyView.
Field‐free spin‐orbit torque domain‐wall synapses integrated with stochastic MTJ neurons enable compact hardware Boltzmann machines. Leveraging intrinsic stochasticity and multi‐level conductance, the system achieves efficient probabilistic learning with high accuracy, demonstrating a scalable spintronic platform for energy‐efficient edge AI.

Constraining f(R,Lm,T) gravity with millisecond pulsar observations

Nuclear Physics B
Pulsars, with their extreme densities and precise measurements, offer an exceptional probe of matter under intense gravity. We examined compact star structures within the extended f(R,Lm,T) gravity framework, incorporating the Ricci scalar, matter ...
