‘We Are Australia’: Unpacking Aboriginal and Torres Strait Islander People's Understandings and Experiences of Australian Identity

Australian Journal of Social Issues, EarlyView.
ABSTRACT Aboriginal and Torres Strait Islander people are the oldest living custodians in the world. However, Australian identity has been purposefully established to exclude Aboriginal and Torres Strait Islander people, contributing to systemic oppression and harmful consequences. Understanding the perspectives and experiences of Aboriginal and Torres

Australian Activists as Storytellers in Digital Spaces: Acquiring Skills, Producing Content and Getting the Message Out

Australian Journal of Social Issues, EarlyView.
ABSTRACT As modes of activism rapidly evolve, activists—both seasoned and emerging—must increasingly navigate a hybrid terrain of both digital and non‐digital engagement. This paper draws on the personal narratives of 16 nascent activists based in Australia to explore how they develop competencies related to digital storytelling, which is critical to ...

The liver‐brain axis: A multidimensional regulatory network implicated in Alzheimer's disease pathogenesis and clinical implications

Animal Models and Experimental Medicine, EarlyView.
Schematic diagram of the core pathways of the liver‐brain axis in regulating AD. The liver regulates cerebral Aβ deposition, tau phosphorylation, and neuroinflammation through pathways such as metabolic detoxification (urea cycle, ketone body metabolism, glutathione antioxidant system), molecular secretion (APOE, CRP, FGF21, IGF‐1), and Aβ clearance ...

Natural Sunlight IR‐Driven Highly Efficient Synthesis of Acetaldehyde From Bioethanol Over Cu/Fe2O3

Angewandte Chemie, EarlyView.
This work reports a Cu/Fe2O3 catalyst for the conversion of bioethanol into valuable acetaldehyde and green hydrogen under both infrared (IR) light and natural sunlight. This IR‐driven system sets a new performance benchmark, with TON and initial TOF enhanced by at least one order of magnitude, enabled by a constructed IR photon‐to‐phonon channel and ...

An Overview on the Second Generation Voltage Conveyor: Features, Design and Applications

IEEE Transactions on Circuits and Systems II: Express Briefs, 2019
This brief presents a comprehensive study on a particular kind of conveyor called second-generation voltage conveyor (VCII). This building block is based on voltage conveying concept and is the dual of second generation current conveyor (CCII). It is shown that VCII is a very useful block in those configurations where CCII is limited, in terms of ...

CMOS Adaptive Biased Second Generation Voltage Conveyor

2023 International Workshop on Biomedical Applications, Technologies and Sensors (BATS), 2023
In this paper, a new second generation voltage conveyor (VCII) topology with adaptive bias is presented. For the first time, adaptive bias has been exploited in a CMOS VCII circuit, with the goal of reducing power consumption without sacrificing transient performance, in order to design an active building block suitable for very low power sensor ...

New simple transistor realizations of second‐ generation voltage conveyor

International Journal of Circuit Theory and Applications, 2020
SummaryIn this paper, two new complementary metal oxide semiconductor (CMOS) realizations for second‐generation voltage conveyor (VCII) are presented. The first proposed VCII has a very simple structure employing only six transistors. The second proposed VCII employs 11 transistors, and none of the transistors at both proposed circuits suffer from the ...

Universal Current Conveyor and Universal Voltage Conveyor Measurements and Modelling

International Conference on Networking, International Conference on Systems and International Conference on Mobile Communications and Learning Technologies (ICNICONSMCL'06), 2006
Modern analogue devices such as current and voltage conveyors are essential parts of broadband active-RC filters. Designers should be equipped with detailed non-linear frequency-dependent models to be able to simulate circuit performances before production. The paper gives a report how the models of conveyors can be composed.

REALIZATION OF LOW-VOLTAGE DIFFERENTIAL VOLTAGE CURRENT CONVEYOR

Journal of Circuits, Systems and Computers, 2012
This paper presents floating gate MOSFET (FGMOS)-based second generation differential voltage current conveyor (DVCCII) at low voltage levels. In analog circuit design, the FGMOS transistors are very often used in low voltage circuits, where the reduction obtained in the transistor apparent threshold voltage is of great importance.
