Large Datasets for the Euro Area and Its Member Countries and the Dynamic Effects of the Common Monetary Policy

open access: yesJournal of Applied Econometrics, EarlyView.
ABSTRACT We introduce EA‐MD‐QD, a new publicly available dataset comprising 1136 macroeconomic time series for the euro area (EA) and its ten largest member countries observed at monthly or quarterly frequency. Since January 2024, EA‐MD‐QD has been updated monthly and continuously revised, providing a valuable resource for policy analysis in the EA ...

Test Study on Carbody Abnormal Vibration of High-speed EMUs

open access: yes, 2014
Carbody abnormal vibration analysis of a high-speed EMUs was researched, mainly containing the wheel tread measurements,carbody vibration on-line test, turn around running and vibration compared before and after repairing profile. The results showed that the change of wheel/rail wear matching in the partial line induced equivalent conicity increasing ...

Seeded‐Growth of ZIF‐8 onto Magnetic Nanoparticles: Smart Nanocarriers with Ultrahigh Drug Loading for AMF‐Triggered Release

open access: yesSmall, EarlyView.
We developed core‐shell iron oxide@ZIF‐8 magnetic‐MOF nanohybrids via a seeded growth method for magnetic hyperthermia‐triggered drug delivery. Cubic cores and thinner shells maximized heating. In‐situ doxorubicin encapsulation achieved 98% loading, better than surface encapsulation. Polymer coating improved stability.
