Bidding Strategy and Clearing Model of Virtual Power Plants in Energy and Inertia Markets

open access: yesInternational Transactions on Electrical Energy Systems
The ongoing decline in system inertia during the energy transition poses serious challenges to frequency stability. Virtual power plants (VPPs) offer a feasible pathway to enhance system frequency support by aggregating distributed inertia resources from

Economic and environmental assessment of alternative energy cooking technologies for households in Uganda

open access: yesScientific African
Access to clean cooking remains a critical challenge in Uganda, where over 90 % of households rely on traditional biomass fuels, which has worsened environmental degradation, gender disparities, and health risks.

β‐Catenin/c‐Myc Axis Modulates Autophagy Response to Different Ammonia Concentrations

open access: yesAdvanced Biology, Volume 9, Issue 3, March 2025.
Ammonia, detoxified by the liver into urea and glutamine, impacts autophagy differently at varying levels. Low ammonia activates autophagy via c‐Myc and β‐catenin, while high levels suppress it. Using Huh7 cells and Spf‐ash mice, c‐Myc's role in cytoprotective autophagy is revealed, offering insights into hyperammonemia and potential therapeutic ...

Performance Auditing of Energy Management Programs [PDF]

open access: yes, 1988
With the oil crisis of the 1970's, energy management programs became important to both the private and public sectors. But with the decrease of oil prices in the mid 1980's, interest in energy conservation programs has declined.

Temperature dependent fracture properties of shape memory alloys: novel findings and a comprehensive model

open access: yesScientific Reports, 2016
Temperature dependent fracture properties of NiTi-based Shape Memory Alloys (SMAs), within the pseudoelastic regime, were analyzed. In particular, the effective Stress Intensity Factor (SIF) was estimated, at different values of the testing temperature ...

Thermodynamic Pathways of Nonequilibrium Solidification in Wire‐Arc Additive Manufacturing Fe‐Based Multicomponent Alloy Structures

open access: yesAdvanced Engineering Materials, EarlyView.
Geometry‐driven thermal behavior in wire‐arc additive manufacturing (WAAM) influences microstructural evolution during nonequilibrium solidification of a chemically complex Fe–Cr–Nb–W–Mo–C nanocomposite system. By comparing different deposits configurations, distinct entropy–cooling rate correlations, segregation, and carbide evolution are revealed ...

Field Report from Collaborative Research Center 1625: Heterogeneous Research Data Management Using Ontology Representations

open access: yesAdvanced Engineering Materials, EarlyView.
A unified research data management framework for heterogeneous materials data is presented. The system integrates multimodal datasets using ontologies and knowledge graphs, enabling interoperability and FAIR (findable, accessible, interoperable, reusable) data principles. By linking data across scales and workflows, it supports reproducible, Artifitial
