Frequency performance analysis of proportional integral-type active disturbance rejection generalized predictive control for time delay systems

open access: yesSystems Science & Control Engineering, 2022
To improve the performance of the Active Disturbance Rejection Control (ADRC) in systems which have large time delay, reduce online computation for Proportional Integral-type Generalized Predictive Control (PI-GPC) method, the Proportional Integral-type ...

Active disturbance rejection control of temperature of thermoelectric module

open access: yesRevista Iberoamericana de Automática e Informática Industrial RIAI, 2021
This article presents an active disturbance rejection approach for the control of the temperature in the cold face of a thermoelectric module fed by a type buck DC-DC converter. The dynamics of the module is seen as a disturbance of an unknown nature and

Three-party quantum secure direct communication based on Greenberger-Horne-Zeilinger states [PDF]

open access: yes, 2006
We present a three-party simultaneous quantum secure direct communication (QSDC) scheme by using Greenberger-Horne-Zeilinger (GHZ) states. This scheme can be directly generalized to $N$-party QSDC by using $n$-particle GHZ states.

By dawn or dusk—how circadian timing rewrites bacterial infection outcomes

open access: yesFEBS Letters, EarlyView.
The circadian clock shapes immune function, yet its influence on infection outcomes is only beginning to be understood. This review highlights how circadian timing alters host responses to the bacterial pathogens Salmonella enterica, Listeria monocytogenes, and Streptococcus pneumoniae revealing that the effectiveness of immune defense depends not only

Robust semicoherent searches for continuous gravitational waves with noise and signal models including hours to days long transients [PDF]

open access: yes, 2016
The vulnerability to single-detector instrumental artifacts in standard detection methods for long-duration quasimonochromatic gravitational waves from nonaxisymmetric rotating neutron stars [continuous waves (CWs)] was addressed in past work [D.

Time after time – circadian clocks through the lens of oscillator theory

open access: yesFEBS Letters, EarlyView.
Oscillator theory bridges physics and circadian biology. Damped oscillators require external drivers, while limit cycles emerge from delayed feedback and nonlinearities. Coupling enables tissue‐level coherence, and entrainment aligns internal clocks with environmental cues.

A Weighted Generalized Maximum Entropy Estimator with a Data-driven Weight

open access: yesEntropy, 2009
The method of Generalized Maximum Entropy (GME), proposed in Golan, Judge and Miller (1996), is an information-theoretic approach that is robust to multicolinearity problem.

Separating the classical and quantum information via quantum cloning [PDF]

open access: yes, 2005
An application of quantum cloning to optimally interface a quantum system with a classical observer is presented, in particular we describe a procedure to perform a minimal disturbance measurement on a single qubit by adopting a 1->2 cloning machine ...
