Quantum Coding via Quasi-Cyclic Block Matrix

open access: yesEntropy, 2023
An effective construction method for long-length quantum code has important applications in the field based on large-scale data. With the rapid development of quantum computing, how to construct this class of quantum coding has become one of the key ...

On the Entropy of Fractionally Integrated Gauss–Markov Processes

open access: yesMathematics, 2020
This paper is devoted to the estimation of the entropy of the dynamical system {Xα(t),t≥0}, where the stochastic process Xα(t) consists of the fractional Riemann–Liouville integral of order α∈(0,1) of a Gauss–Markov process.

Deep Levels and Electron Paramagnetic Resonance Parameters of Substitutional Nitrogen in Silicon from First Principles

open access: yesNanomaterials, 2023
Nitrogen is commonly implanted in silicon to suppress the diffusion of self-interstitials and the formation of voids through the creation of nitrogen–vacancy complexes and nitrogen–nitrogen pairs.

A robust semantics hides fewer errors [PDF]

open access: yes, 2009
In this paper we explore how formal models are interpreted and to what degree meaning is captured in the formal semantics and to what degree it remains in the informal interpretation of the semantics.

Human-Machine Duality: What’s Next in Cognitive Aspects of Artificial Intelligence?

open access: yesIEEE Access, 2022
The goal of the paper is to find means for the unification of human-machine duality in collective behavior of people and machines, by conciliating approaches that proceed in opposite directions. The first approach proceeds top-down from non-formalizable,

An Abstraction Theory for Qualitative Models of Biological Systems [PDF]

open access: yes, 2010
Multi-valued network models are an important qualitative modelling approach used widely by the biological community. In this paper we consider developing an abstraction theory for multi-valued network models that allows the state space of a model to be ...

Measure Transformer Semantics for Bayesian Machine Learning [PDF]

open access: yesLogical Methods in Computer Science, 2013
The Bayesian approach to machine learning amounts to computing posterior distributions of random variables from a probabilistic model of how the variables are related (that is, a prior distribution) and a set of observations of variables.

Exploring Routes to Enhance the Calculation of Free Energy Differences via Non-Equilibrium Work SQM/MM Switching Simulations Using Hybrid Charge Intermediates between MM and SQM Levels of Theory or Non-Linear Switching Schemes

open access: yesMolecules, 2023
Non-equilibrium work switching simulations and Jarzynski’s equation are a reliable method for computing free energy differences, ΔAlow→high, between two levels of theory, such as a pure molecular mechanical (MM) and a quantum mechanical/molecular ...

Solutions of the Yang–Baxter Equation and Automaticity Related to Kronecker Modules

open access: yesComputation, 2023
The Kronecker algebra K is the path algebra induced by the quiver with two parallel arrows, one source and one sink (i.e., a quiver with two vertices and two arrows going in the same direction). Modules over K are said to be Kronecker modules.

From Causes for Database Queries to Repairs and Model-Based Diagnosis and Back [PDF]

open access: yes, 2014
In this work we establish and investigate connections between causes for query answers in databases, database repairs wrt. denial constraints, and consistency-based diagnosis.
