Allosteric modulation of protein kinase A in individuals affected by NLPD‐PKA, a neurodegenerative disease in which the PRKAR1B L50R variant is expressed

The FEBS Journal, EarlyView.
In healthy neurons, Protein kinase A (PKA) forms a tetrameric holoenzyme enabling precise allosteric regulation. We characterized a novel neurodegenerative disease, neuronal loss, and parkinsonism driven by PRKAR1B mutation (NLPD‐PKA), demonstrating disrupted holoenzyme assembly, reduced cooperativity, and increased catalytic subunit nuclear ...

Do temporary changes in earnings caused by mean reversion affect firms’ refinancing decisions?

Journal of Financial Research, EarlyView.
Abstract We develop a dynamic two‐stage trade‐off model with refinancing when earnings are mean reverting. Our model predicts a negative relation between profitability and leverage at refinancing due to conservative debt increases. With multiple rounds of refinancing, the leverage–profitability relation may turn positive when firms have substantial ...

Partial Observability of Implied Volatility Matrices: Identification and Covolatilities Filtering

Mathematical Finance, EarlyView.
ABSTRACT Whereas data on implied volatilities are available for a large number of assets, this is less frequently the case of implied covolatilities. We introduce a new approach based on static and dynamic Wishart models to solve this problem of missing data.

Neurogenomic landscape associated with status‐dependent cooperative behaviour

Molecular Ecology, EarlyView.
Abstract The neurogenomic mechanisms mediating male–male reproductive cooperative behaviours remain unknown. We leveraged extensive transcriptomic and behavioural data on a neotropical bird species (Pipra filicauda) that performs cooperative courtship displays to understand these mechanisms.
