Tailoring the Position of Ester Group on N-Alkyl Chains of Benzotriazole-based Small Molecule Acceptors for High-Performance Organic Solar Cells.

Angewandte Chemie
Side chain engineering plays a vital role in exploring high-performance small molecule acceptors (SMAs) for organic solar cells (OSCs). In this work, we designed and synthesized a series of A-DA'D-A type SMAs by introducing different N-substituted alkyl ...

Severe Weather and the Macroeconomy

American Economic Journal: Macroeconomics
We investigate the impact of severe weather shocks on the US macroeconomy over the past 60 years. Using a nonlinear vector autoregressive model, we find robust evidence of time-varying effects.

E31 Positron Emission Tomography Imaging Of Phosphodiesterase 10 A Enzyme And Dopamine D2 Receptor In Huntington's Disease Gene Expansion Carriers

Journal of Neurology, Neurosurgery & Psychiatry, 2014
Background Degeneration of striatal medium-spiny neurons is a pathological feature of Huntington´s disease (HD). D2 receptor imaging with positron emission tomography (PET) is a marker of neuronal integrity in HD. Phosphodiesterase 10A (PDE10A) enzyme is highly enriched in the striatal medium-spiny neurons and is a target of interest for drug ...

Delayed Overshooting: The Case for Information Rigidities

American Economic Journal: Macroeconomics
We provide evidence that the delayed overshooting puzzle reflects a slow adjustment of exchange rate expectations to monetary policy shocks rather than a failure of uncovered interest parity.
