Ground‐ and Excited‐State Mixed Valency in a 4,4′‐Bipyridine‐Bridged Bimetallic Di‐Ruthenium Complex

open access: yesEuropean Journal of Inorganic Chemistry, EarlyView.
Photoinduced mixed‐valence interactions across a 4,4′‐bpy bridge were studied. MLCT excited states in the bimetallic complex are longer‐lived than in the monometallic reference, thanks to metal–metal electronic coupling and hole delocalization, but are still shorter than the nanosecond timescale relevant for diffusional reactivity.

Policy Networks and Policy Entrepreneurship in the EU: Explaining Structural Policy Change in Pharmaceutical Innovation Incentives and Health Technology Assessment

open access: yesEuropean Policy Analysis, EarlyView.
ABSTRACT Policy process research has excelled in explaining structural policy change within national settings, but extensions and applications to the EU level have long proven challenging for scholars. Given that the EU is currently experiencing its longest period of Treaty stability since the 1980s—having evolved into a sui generis political system ...

Earthquake and Tsunami NaTech Risk Assessment for Oil Storage Facilities

open access: yesEarthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT Interaction of natural and technological hazards (NaTech) events, such as tsunamis and earthquakes, can affect industrial facilities such as those featuring anchored atmospheric storage tanks. Consequences of natural events on this kind of installation may include the release of hazardous substances, which in turn can lead to industrial ...

Prediction of Pipeline Defect Depth and Classification Based on CatBoost

open access: yesEnergy Science &Engineering, EarlyView.
Obtaining detection data using in‐line pipeline inspection, the synthetic minority oversampling technique (SMOTE) is applied to expand the sample set, thereby increasing the number of minority‐class samples. This approach effectively improves minority‐class detection and enhances pipeline safety assessment. ABSTRACT Magnetic flux leakage detection is a

Intelligent Control Framework of District Heating Systems Considering Waste Heat Utilization in Data Centers

open access: yesEnergy Science &Engineering, EarlyView.
A deep reinforcement learning–based control architecture is proposed to coordinate heat pumps, thermal storage, renewable energy, and demand response in data center waste heat recovery systems. The agent learns optimal control actions from system states and reward feedback to achieve electrical–thermal co‐optimization under realistic operational ...
