Decomposition–Coordination of Double-Layer MPC for Constrained Systems

open access: yesEntropy, 2022
Large-scale industrial processes usually adopt centralized control and optimization methods. However, with the growth of the scale of industrial processes leading to increasing computational complexity, the online optimization capability of the double ...

Learning in High-Dimensional Multi-response Linear Models with Quantum non-Oracular Search (when the range of the coefficient matrix is known) [PDF]

open access: yesCientífica
This paper studies the high-dimensional, low-rank multivariate linear model, which provides us with relevant information given a sample, with the help of a hybrid quantum computing algorithm (combining quantum and classical computing to solve a problem).

Impact of fibroblast growth factor-23 on blood pressure and pulse pressure in hemodialysis patients; a multicenter study [PDF]

open access: yesJournal of Nephropathology, 2019
Introduction: Hypertension seems to be a major problem in dialysis patients. Fibroblast growth factor-23 (FGF-23) appears to be a risk factor for mortality in patients with end-stage renal disease (ESRD). Objectives: This study aims to investigate FGF-23

Spectral-spatial adversarial network for nonlinear hyperspectral unmixing of imbalanced datasets

open access: yesInternational Journal of Applied Earth Observations and Geoinformation, 2023
With its successful application in various fields, hyperspectral unmixing (HU) technology has received extensive attention in remote sensing processing. Recently, various autoencoders based on the linear mixing model (LMM) have been proposed to provide a

The regular multivariate quadratic problem

open access: yesDesigns, Codes and Cryptography
Abstract In this work, we introduce a novel variant of the multivariate quadratic problem, which is at the core of one of the most promising post-quantum alternatives: multivariate cryptography. In this variant, the solution of a given multivariate quadratic system must also be regular, i.e.

THE MULTIVARIATE QUADRATIC POWER PROBLEM OVER ZN IS NP-COMPLETE

open access: yesInformation Technology and Control, 2012
New NP-complete problem, named as multivariate quadratic power (MQP) problem, is presented. It is based on solution of multivariate quadratic power system of equations over the semigroup Zn, denoted by MQP(Zn), where n is positive integer. Two sequential polynomial-time reductions from known NP-complete multivariate quadratic (MQ) problem over the ...

Security Analysis of Reusing Vinegar Values in UOV Signature Scheme

open access: yesIEEE Access
Multivariate quadratic equation-based cryptographic algorithms are one of the promising post-quantum alternatives to current public-key cryptographic algorithms based on the discrete logarithm problem and the integer factorization problem. In this paper,

A family of weak keys in HFE and the corresponding practical key-recovery

open access: yesJournal of Mathematical Cryptology, 2012
The HFE (hidden field equations) cryptosystem is one of the most interesting public-key multivariate schemes. It has been proposed more than 10 years ago by Patarin and seems to withstand the attacks that break many other multivariate schemes, since ...

Algebraic Side Channel Attack on Trivium and Grain Ciphers

open access: yesIEEE Access, 2017
Solving a system of multivariate quadratic equations obtained through algebraic cryptanalysis is a nondeterministic polynomial time-complete problem. Owing to the trend of stream ciphers based on nonlinear update, the success of algebraic attacks has ...
