Entangled political institutions and forms: From corporatisation to treaty

Australian Journal of Public Administration, EarlyView.
Abstract The lands and waters now called Australia have been home to diverse political ordering and institutions for thousands of generations. The comparatively very recent arrival of settlers and the violent imposition of their political structures and institutions have forced First Nations to respond to, adapt to, resist, and refuse colonial ...

3 sampled-data control of nonlinear systems

, 2006
This chapter provides some of the main ideas resulting from recent developments in sampled-data control of nonlinear systems. We have tried to bring the basic parts of the new developments within the comfortable grasp of graduate students.

Robust Passivity-based Control Integrated with UDE Strategy for Grid-Tied Inverter

Elektronika ir Elektrotechnika
Uncertainties caused by parametric variations, external disturbances, and modelling errors of grid-tied inverters (GTI) make it challenging to select a proper gain for the desired controller.

Dentists' Knowledge and Clinical Practice Regarding Splinting After Dental Trauma: A Guideline‐Based Cross‐Sectional Study

Dental Traumatology, EarlyView.
ABSTRACT Background/Aim Traumatic dental injuries require prompt, guideline‐based management, and splinting is critical for healing and prognosis. The aim of this cross‐sectional study was to assess and compare International Association of Dental Traumatology (IADT) guideline–based splinting knowledge among general dentists and dental specialists ...

Control by Interconnection and Standard Passivity-Based Control of Port-Hamiltonian Systems [PDF]

, 2008
The dynamics of many physical processes can be suitably described by Port-Hamiltonian (PH) models, where the importance of the energy function, the interconnection pattern and the dissipation of the system is underscored.

Constant Power Load Stabilization in DC Microgrid Systems Using Passivity-Based Control With Nonlinear Disturbance Observer

IEEE Access, 2020
This paper aims to present a robust passivity-based control (PBC) strategy to solve the instability problem caused by the constant power loads (CPLs) in dc microgrid systems.

Directional information flow in human frataxin defines allosteric pathways connecting the hydrophobic core to the iron‐binding ridge

The FEBS Journal, EarlyView.
Human frataxin deficiency causes Friedreich's ataxia, yet how iron‐binding events are communicated across the protein is unclear. Using transfer entropy analysis of molecular dynamics simulations, we identify buried hydrophobic core leucines (LEU136, LEU140) as the source of directional signaling toward the iron‐binding acidic ridge.

Stabilization of DC–DC buck converter with unknown constant power load via passivity‐based control plus proportion‐integration

IET Power Electronics, 2021
It is known that constant power load (CPL) may cause a negative impedance, which seriously affects the stability of power system. In this paper, a new control algorithm for DC–DC buck converter feeding unknown CPL is proposed. First, under the assumption

Indoleamine 2,3‐Dioxygenase 1 as an Adjunctive Histopathological Marker of Cholangitis Activity in Primary Biliary Cholangitis

Hepatology Research, EarlyView.
IDO‐1 immunostaining identifies primary biliary cholangitis even in morphologically subtle bile duct lesions. IDO‐1 expression reflects cholangitis activity and is suppressed by ursodeoxycholic acid treatment, indicating its value as a dynamic diagnostic adjunct rather than a static marker of chronic damage.
