Co‐Optimisation of Battery Energy Storage Systems for Voltage Regulation and Reverse Power Flow Control in PV‐Enriched Low Voltage Distribution Network

open access: yesIET Smart Energy Systems, EarlyView.
A hybrid GA–PSO framework determines the optimal placement and sizing of distributed battery energy storage systems in a PV‐enriched low voltage feeder, whereas dynamic consensus control (DCC) coordinates their operation. The integrated approach mitigates voltage rise and reverse power flow and promotes balanced utilisation of multiple storage units ...

Visualization Guidelines for the Control Room: An Evaluation of Visual Alert Encoding with Domain Experts

open access: yesComputer Graphics Forum, EarlyView.
Abstract Visualization is routinely used in control rooms to maintain situational awareness of complex sociotechnical systems. While control room design often incorporates human factors engineering to identify the information presented, it is not unusual for control room visual encodings to rely closely on operator experience and historical encodings ...

Shark preferences: Only subtle effects of electromagnetic field exposure and substrate type on small‐spotted catshark (Scyliorhinus canicula) behaviour

open access: yesJournal of Fish Biology, EarlyView.
Abstract Offshore wind energy plays a crucial role in the transition to low‐carbon power generation. The expansion of offshore wind farms (OWFs) introduces anthropogenic electromagnetic fields (EMFs) from subsea power cables. Elasmobranchs, including sharks and rays, are sensitive to natural electric and magnetic fields used for navigation and prey ...

Policing the safety net: Medical and carceral management of violence in a Los Angeles County public hospital

open access: yesMedical Anthropology Quarterly, EarlyView.
Abstract Medical anthropologists have long shown how hospitals function as spaces of both care and control, yet the entanglement of policing and trauma care remains understudied. This paper offers an ethnographic account of how trauma surgeons in a Los Angeles County hospital navigate the embedded presence of police within their clinical work.

Beyond Risk Reduction: Leveraging Multiple Resilience Dividend Concept for Transformative Adaptation Planning

open access: yesClimate Resilience and Sustainability, Volume 5, Issue 2, December 2026.
This paper presents a framework for Multiple Resilience Dividends (MRD) that proposes shift climate change adaptation from a narrow risk‐focused perspective to a broader, multi‐objective systems approach. By recognizing the diverse range of benefits that adaptation measures can provide, practitioners can go beyond merely avoiding losses.
