CAAI Transactions on Intelligence Technology, EarlyView.ABSTRACT Accurate surface‐pressure prediction over broad operating envelopes is critical for supersonic aerodynamic analysis and design. To overcome the bottlenecks of traditional computational fluid dynamics (CFD) in real‐time performance and computational efficiency, data‐driven deep learning methods have emerged. However, existing data‐driven models

High Voltage, EarlyView.ABSTRACT This paper investigates the generation mechanism of quasi‐power‐frequency resonant overvoltage triggered by multiple lightning strikes in high‐voltage alternating current (HVAC) systems equipped with shunt reactors. Based on field measurements from a 500 kV AC system, equivalent and simplified circuit models have been established to analyse ...

In situ mapping of iron oxidation in laminar metal fuel flames using X‐ray absorption spectroscopy
Journal of Synchrotron Radiation, EarlyView.For the first time an iron metal flame has been mapped by in situ X‐ray absorption spectroscopy. Strong gradients in oxidation state and phase composition across the metallic core and the flame front were found with FeO peaking at the visible flame front and Fe3O4 forming further beyond.Metal fuels such as iron are promising carbon‐free energy carriers

The Political Economy of Tourism: Introduction to the Special Collection
The Political Quarterly, EarlyView.Abstract Tourism is one of the fastest‐growing internationally traded service industries. The articles in this special collection examine the circumstances under which it can act as a driver of sustainable, equitably shared growth. The introduction argues that tourism offers a promising path to regional development—not only in southern Europe and the ...

Journal of the Royal Anthropological Institute, EarlyView.Over the last 25 years, perceptions of the early prehistory of Northwest Africa have undergone radical changes due to new fieldwork projects and a corresponding growth in scientific interest in the region. Much of this work has been focused in Morocco, known for its extremely rich fossil and archaeological records in caves and rock shelters.

Journal of the Royal Anthropological Institute, EarlyView.Economic anthropologists now carry out fieldwork in settings for which the ethnographic method was never designed, amongst powerful financial actors who are notoriously difficult to access, and in contexts which transcend geographical boundaries. This has engendered a re‐orientation of anthropology, to consider not only the economic lives of people but

Firearm Safety in a Country of Arms
The Milbank Quarterly, EarlyView.Policy Points Firearm safety policy in the United States cannot succeed through legislation alone; effective interventions must also address the social, economic, and infrastructural conditions that shape perceptions of safety. Evidence suggests that place‐based investments can reduce violence and firearm deaths while strengthening social cohesion and ...
