Gate level optimisation of primitive operator digital filters using a carry save decomposition [PDF]

open access: yes, 1994
This paper introduces a method for optimising digital filter realisations at the gate level. The method is based on a derivative of the primitive operator approach of Bull and Horrocks which is extended using a carry-save decomposition of the primitive ...

Operator matrices and systems of evolution equations

open access: yes, 1996
Many initial value problems like Volterra equations, delay equations or wave equations can be reduced to an abstract Cauchy problem governed by an operator matrix.

A natural space of functions for the Ruelle operator theorem [PDF]

open access: yes, 2007
We study a new space, $R(X)$, of real-valued continuous functions on the space $X$ of sequences of zeros and ones. We show exactly when the Ruelle operator theorem holds for such functions.

Neighbor-Induction and Population-Dispersion in Differential Evolution Algorithm

open access: yesIEEE Access, 2019
The differential evolution (DE) optimization algorithm predominantly relies on elite individuals and random difference to direct evolution. Although the strategy is clear and easy to implement, identifying a suitable direction for the DE mutation ...

Generalized Yosida Approximations Based on Relatively A-Maximal m-Relaxed Monotonicity Frameworks

open access: yesAbstract and Applied Analysis, 2013
We introduce and study a new notion of relatively A-maximal m-relaxed monotonicity framework and discuss some properties of a new class of generalized relatively resolvent operator associated with the relatively A-maximal m-relaxed monotone operator and ...

Time ordering effects and destruction of quasiparticles in two-dimensional holographic CFTs

open access: yesJournal of High Energy Physics
In this paper, we investigate the entanglement dynamics induced by a composite operator, defined as the local operator evolved with the time evolution operator constructed out of the Euclidean and Lorentzian ones.

On Prigogine's approaches to irreversibility: a case study by the baker map

open access: yesDiscrete Dynamics in Nature and Society, 2004
The baker map is investigated by two different theories of irreversibility by Prigogine and his colleagues, namely, the Λ-transformation and complex spectral theories, and their structures are compared.

Relaxation process during complex time evolution in two-dimensional integrable and chaotic CFTs

open access: yesJournal of High Energy Physics
We investigate the complex time evolution of a vacuum state with the insertion of a local primary operator in two-dimensional conformal field theories (2d CFTs).

Efficient Circuit Implementations of Continuous-Time Quantum Walks for Quantum Search

open access: yesEntropy
Quantum walks are a powerful framework for simulating complex quantum systems and designing quantum algorithms, particularly for spatial search on graphs, where the goal is to find a marked vertex efficiently.
