Cold case: The disappearance of Egypt bee virus, a fourth distinct master strain of deformed wing virus linked to honeybee mortality in 1970’s Egypt

open access: yesVirology Journal, 2022
In 1977, a sample of diseased adult honeybees (Apis mellifera) from Egypt was found to contain large amounts of a previously unknown virus, Egypt bee virus, which was subsequently shown to be serologically related to deformed wing virus (DWV).

The Empirics of International Monetary Transmission: Identification and the Impossible Trinity

open access: yes, 2010
The transmission of monetary policy across borders is central to many open economy models. Research has tried to evaluate the “impossible trinity” through estimating international interest rate linkages under alternative exchange rate regimes using ...

Numerical investigation on low-frequency noise damping performances of Helmholtz resonators with an extended neck in presence of a grazing flow

open access: yesJournal of Low Frequency Noise, Vibration and Active Control, 2021
In this work, modified designs of Helmholtz resonators with extended deflected neck are proposed, numerically evaluated and optimized aiming to achieve a better transmission loss performance over a broader frequency range.
