Tests of the CAPM under Structural Change

, 2014
In accordance with the empirical regularity of time-varying betas, following the work of Bai and Perron (1998, 2003), we estimate and test for the Sharpe-Lintner CAPM by allowing for structural change(s) in betas.

C2α‐carbanion‐protonating glutamate discloses tradeoffs between substrate accommodation and reaction rate in actinobacterial 2‐hydroxyacyl‐CoA lyase

FEBS Open Bio, EarlyView.
Enzymes of the 2‐hydroxyacyl‐CoA lyase group catalyze the condensation of formyl‐CoA with aldehydes or ketones. Thus, by structural adaptation of active sites, practically any pharmaceutically and industrially important 2‐hydroxyacid could be biotechnologically synthesized. Combining crystal structure analysis, active site mutations and kinetic assays,

Population-ageing, structural change and productivity growth

Population-ageing is one of the traditional topics of development and growth theory and a key challenge to most modern societies. We focus on the following aspect: Population-ageing is associated with changes in demand-structure, since demand-patterns ...

A light‐triggered Time‐Resolved X‐ray Solution Scattering (TR‐XSS) workflow with application to protein conformational dynamics

FEBS Open Bio, EarlyView.
Time‐resolved X‐ray solution scattering captures how proteins change shape in real time under near‐native conditions. This article presents a practical workflow for light‐triggered TR‐XSS experiments, from data collection to structural refinement. Using a calcium‐transporting membrane protein as an example, the approach can be broadly applied to study ...
