Symmetries and Scale Invariance in Global Maps of Quantum Circuits

Proceedings
We present a combinatorial analysis of any maximal set of gate compositions parameterized over a finite alphabet which revealed an underlying fractal structure. Results are presented as global maps in the form of large 2D arrays where each row stands for

On the spectral norms of r-circulant matrices with the biperiodic Fibonacci and Lucas numbers

Journal of Inequalities and Applications, 2017
In this paper, we present new upper and lower bounds for the spectral norms of the r-circulant matrices Q=Cr((ba)ξ(1)2q0,(ba)ξ(2)2q1,(ba)ξ(3)2q2,…,(ba)ξ(n)2qn−1) $Q=C_{r} ( (\frac{b}{a} )^{\frac{\xi (1)}{2}}q_{0}, (\frac{b}{a} )^{\frac{\xi(2)}{2}}q_{1}, (

Monolithic Framework to Simulate Fluid‐Structure Interaction Problems Using Geometric Volume‐of‐Fluid Method

International Journal for Numerical Methods in Fluids, EarlyView.
A three‐dimensional fluid‐structure interaction (FSI) framework is developed using the geometric volume‐of‐fluid (VOF) interface capturing method and applied to assess largescale turbulent FSI interactions. The monolithic FSI framework is extensively validated, and despite the discontinuities across the interface, the FSI framework delivers stable and ...

A new condition for Root Clustering in PMI regions [PDF]

Revista Română de Informatică și Automatică
This paper proposes a new condition for the root clustering of a real matrix A in a complex region D defined by a polynomial matrix inequality (PMI region). For a general case, a sufficient condition is given so that the eigenvalues of A lie in D .

Waiting Time Prioritisation for Public and Private Providers: Evidence From Hip Replacement Surgery

Health Economics, EarlyView.
ABSTRACT Waiting times for planned health care treatments have been increasing in England and other OECD countries. One policy to reduce the impact of waiting times on patients' health is for doctors to prioritise patients according to their health status. This study tests the extent to which publicly‐funded patients in poorer health are prioritised on

Industry Portfolio Volatility Connections and Industry Portfolio Returns

International Journal of Finance &Economics, EarlyView.
ABSTRACT This paper tracks dynamic connections that form among daily US industry portfolio return volatilities using a Bayesian time‐varying parameter VAR model. Market participants often focus on sectors to filter vast amounts of information, and this focus results in cross‐industry return predictability. We characterise connections that form over the

Persistent Tensors and Multiqudit Entanglement Transformation [PDF]

Quantum
We construct a lower bound of the tensor rank for a new class of tensors, which we call $\textit{persistent tensors}$. We present three specific families of persistent tensors, of which the lower bound is tight.

NTECARS: A Nonthermal Equilibrium CARS Spectra Fitting Code

Journal of Raman Spectroscopy, EarlyView.
We present NTECARS, an open‐source code written in Julia for the calculation and fitting of CARS spectra under nonequilibrium conditions. Rovibrational distributions can be flexibly modeled and fitted for different use cases. The code currently implements CO2$$ \mathrm{C}{\mathrm{O}}_2 $$ and N2$$ {\mathrm{N}}_2 $$ molecules and is validated under ...

Suppression of Oscillation and Ghosting in RF‐Spoiled Gradient‐Echo‐Based Dynamic Imaging

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose This study aims to address the suppression of oscillation and ghosting appearing in RF‐spoiled gradient‐echo‐based dynamic imaging, which is caused by the pseudo‐steady state (PSS) of magnetization. Theory and Methods We extended the concept of the previous RF phase‐cycle‐adapted averaging method to RF‐spoiled gradient‐echo‐based cine (

Approximate Reachability for Feedback Linearizable Systems

Optimal Control Applications and Methods, EarlyView.
The backwards reachable set for a dynamical system is the set of states for which there exists a constraint admissible trajectory that reaches a given terminal set. Conventional grid‐based approaches for computing these sets are intractable for many applications.
