Nonnormality and the localized control of extended systems [PDF]

Phys. Rev. E 67, 067201 (2003), 2002
The idea of controlling the dynamics of spatially extended systems using a small number of localized perturbations is very appealing - such a setup is easy to implement in practice. However, when the distance between controllers generating the perturbations becomes large, control fails due to increasing sensitivity of the system to noise and ...

Sensitivity Minimization by Strongly Stabilizing Controllers for a Class of Unstable Time-Delay Systems [PDF]

IEEE Transactions on Automatic Control, vol. 54, no. 3, pp. 590-595, 2009, 2020
Weighted sensitivity minimization is studied within the framework of strongly stabilizing (stable) H-infinity controller design for a class of infinite dimensional systems. This problem has been solved by Ganesh and Pearson, [11], for finite dimensional plants using Nevanlinna-Pick interpolation.

Detailed kinship estimation for detecting bias among breeding families in a reintroduced population of the endangered bagrid catfish Tachysurus ichikawai

Population Ecology, EarlyView.
In the process of captive breeding and reintroduction of endangered animal species, it is crucial to minimize familial bias in reproductive success during the reintroduction phase to preserve genetic diversity. In this study, we attempted to identify the familial lineage of individuals of the endangered bagrid fish Tachysurus ichikawai born at the ...

Bode Integral Limitation For Irrational Systems [PDF]

arXiv, 2022
Bode integrals of sensitivity and sensitivity-like functions along with complementary sensitivity and complementary sensitivity-like functions are conventionally used for describing performance limitations of a feedback control system. In this paper, we investigate the Bode integral and evaluate what happens when a fractional order Proportional ...

FoxO1 signaling in B cell malignancies and its therapeutic targeting

FEBS Letters, EarlyView.
FoxO1 has context‐specific tumor suppressor or oncogenic character in myeloid and B cell malignancies. This includes tumor‐promoting properties such as stemness maintenance and DNA damage tolerance in acute leukemias, or regulation of cell proliferation and survival, or migration in mature B cell malignancies.

A preliminary study on the Average Maximum Velocity Sensitivity index from flow velocity variation in quality control for Color Doppler

Measurement: Sensors, 2021
Color Doppler (CD) is one of the most used ultrasound (US) Doppler techniques as it allows the 2D representation of blood flow. Even if a clarification on whether such technique provides qualitative or quantitative diagnostic information on velocity ...

emgr—The Empirical Gramian Framework

Algorithms, 2018
System Gramian matrices are a well-known encoding for properties of input-output systems such as controllability, observability or minimality. These so-called system Gramians were developed in linear system theory for applications such as model order ...

The [2Fe‐2S] cluster of mitochondrial outer membrane protein mitoNEET has an O2‐regulated nitric oxide access tunnel

FEBS Letters, EarlyView.
The mitochondrial outer membrane iron–sulphur ([Fe‐S]) protein mitoNEET is a target of the type‐2 diabetes drug pioglitazone. Its unknown molecular function is linked to respiratory complex activity and mitochondrial function. We discovered that O2 protects the mitoNEET [2Fe‐2S] cluster against NO oxidation and desensitization towards reduction by H2S.

Quantification and Mitigation of Unfairness in Active Power Curtailment of Rooftop Photovoltaic Systems Using Sensitivity Based Coordinated Control

Energies, 2016
With increasing photovoltaic (PV) penetration in low voltage networks (LVNs), voltage regulation is a challenge. Active power curtailment (APC) is one possible solution for mitigating over voltages resulting from active power injection in LVNs.
