A Review of Overcurrent Protection in Smart Grids Under Cyber‐Physical Threats With a Cyber‐Physical Evaluation Framework

Energy Science &Engineering, EarlyView.
By manipulating current and voltage measurements, an assailant can induce unwanted relay action while attempting to avoid detection. Detecting advanced cyber intrusions in power protection environments requires specialised data analysis and anomaly detection methods.

A Resilience‐Based Reward‐Penalty Scheme for Hardening Electricity Distribution Assets Against High‐Impact, Low‐Probability Disasters

Energy Science &Engineering, EarlyView.
This paper introduces a novel resilience‐based reward‐penalty scheme (RPS) for electricity grids facing high‐impact, low‐probability (HILP) disasters. By modeling the costs of proactive asset immunization against reactive RPS penalties, our analysis conclusively demonstrates that long‐term investment in grid resilience is the more economically rational

Prompting, Facilitating, and Legitimizing: How Work‐Life Flexibility Policies and Relational Others Shape Boundary Management

Human Resource Management, EarlyView.
ABSTRACT As hybrid working blurs boundaries between work and nonwork, it is critical we understand how these boundaries are negotiated by employees. Existing literature establishes that work‐life flexibility policies and relational others shape their boundary management, yet the mechanisms through which they do so remain underspecified.

Bio‐inspired artificial retina with receptive fields for in‐sensor multiply‐and‐accumulate operations

InfoMat, EarlyView.
We developed a bio‐inspired artificial retina in which curved artificial receptive fields composed of perovskite photoconductors perform multiply‐and‐accumulate operations through in‐sensor computing. This architecture simultaneously realized the structural efficiency of human eyes (compact single‐lens imaging system) and functional advantages of ...

Examining New Donors in the OECD's Development Assistance Committee

Journal of International Development, EarlyView.
ABSTRACT How do emerging donors integrate into the existing international aid architecture? While the existing literature focuses largely on emerging donors from the Global South, such as Brazil, China, India and Russia, there are many emerging donors from the Global North that have joined the OECD's Development Assistance Committee (DAC)—the premier ...
