New Technology, Work and Employment, EarlyView.ABSTRACT Digital labour groups (DLGs)—online groups focusing on labour issues—are emerging as new actors in employment relations. While existing research documents various aspects of DLGs' activities, there is limited understanding of their impact on industrial relations (IR) or how an impact is achieved.

The Doherty Power Amplifier: Design strategy
, 2015 This paper shows a proposal of methodology for designing Doherty Power Amplifiers (DPAs) with arbitrary output-back-off (OBO), main and peak devices. As a demonstration, a 7.5dB OBO DPA has been designed, using two devices from Cree Inc, and simulated in

The Journal of Physiology, EarlyView.Abstract figure legend Schematic illustrating the in silico study pipeline. A total of 50,000 virtual myocytes were generated, which were then filtered to 7093 myocytes that fit experimentally constrained biomarkers for physiological electrical and calcium behaviour under wild‐type conditions.

The Journal of Physiology, EarlyView.Abstract figure legend A mechanistic framework linking sex‐dependent dynamical instability to proarrhythmic risk. Sex‐specific human ventricular models show that upstream modulators, including biological sex, hormones, drugs and heart disease, promote steeper APD restitution in female than male and enhance dynamical instability.

Design of CMOS Doherty Power Amplifier
, 2014 This thesis presents a fully integrated transformer-based Doherty power amplifier in a standard 90 nm CMOS process. Doherty architecture has been proposed to enhancement the average efficiency of the transmitter, and improve efficiency under the back-off.

What drives animal responses to high severity fire? The role of functional traits
Biological Reviews, Volume 101, Issue 6, Page 2613-2633, December 2026.ABSTRACT Fire regimes are changing worldwide, with increases in the frequency, extent, and severity of fires posing growing risks to biodiversity. Fire severity – the degree of habitat alteration following fire – strongly influences both immediate survival and long‐term recovery of fauna.

A 2.14GHz Driver-stage Power Amplifier for Doherty Power Amplifier
DEStech Transactions on Computer Science and Engineering, 2017 This paper presented a high power amplifier drive a Doherty power amplifier. By using computer software to design and test instrument to adjust, the result shows the driver-stage power amplifier that is made of the MRF8S21100H from NXP company meet the 15dB gain, and 42% power added-efficiency (PAE) at the maximum output power.
