Why Do I Do What I Do? How Searching for Meaning at Work Can Facilitate the Spread of Unethical Conduct through Organizations

Journal of Management Studies, EarlyView.
Abstract Existing research explains the trickle‐down of unethical leader behaviour in organizations primarily in terms of social learning and social exchange processes. We highlight a key limitation of these explanations and propose a novel, meaning‐based mechanism.

From Online Gatherings to Industrial Relations Actors: A Framework for Understanding the Impacts of Digital Labour Groups

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.

Extracellular ionic concentration modulates arrhythmias in a simulated population of human ventricular myocytes with long QT syndrome type 3

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.

Load Mismatch Compensation of Load-Modulated Power Amplifiers: A Comprehensive Review

Energies
With the diversification, acceleration, and arraying of wireless communication systems, power amplifiers (PAs) face stricter demands in terms of RF operation bandwidth, high-efficiency power range, and load mismatch compensation.

Beat‐to‐beat variability of ventricular repolarization reveals sex‐specific instability and proarrhythmic risk

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.

Extended Bandwidth Doherty Power Amplifier for Carrier Aggregated Signals [PDF]

, 2014
In the conventional classes of power amplifiers the efficiency drops at power back-off, whereas in order to maximize the spectral efficiency and data rate, wireless communication standards employ signals with high peak to average power ratio.
