On the Interaction of the Photovoltaic Response With Ferroelectric and Magnetic Domains: Magnetoelectric Control of the Photovoltaic Response in BiFeO3 Thin Films

Small Methods, EarlyView.
This study demonstrates tunable photovoltaic responses in pure, polycrystalline BiFeO3 thin films, controlled by external electric and magnetic fields. By aligning ferroelectric domains and leveraging magnetoelectric coupling, the photogeneration is amplified up to seven times.

Design of compact balanced ultra‐wideband bandpass filter with half mode dumbbell DGS

Electronics Letters, 2016
A new compact balanced ultra‐wideband (UWB) bandpass filter using half mode dumbbell defected ground structure (DGS) is presented. To realise the UWB response, the ‘T’ shape multiple‐mode resonator with short‐ended stub is employed.

In rats, neurodevelopmental disorders induced by maternal hypoxia are associated with attenuated excitatory neurotransmission in the cingulate cortex

British Journal of Pharmacology, EarlyView.
Background and Purpose Maternal hypoxia is a recognised risk factor for neurodevelopmental disorders in offspring. Although rodent models of hypoxia have been reported, the detailed pathogenesis of maternal hypoxia‐induced neurodevelopmental disorders remains unclear.

Is That a Threat? How Types of Stakeholder and Reputational Threat Matter for Gaining Influence in Regulatory Rulemaking

Regulation &Governance, EarlyView.
ABSTRACT This paper assesses what type of comments are most useful to what type of stakeholder in gaining influence during public consultations. Theoretically, the paper approaches stakeholders' consultation comments as reputational threats from key audiences that the agency needs to respond to.
