Synoptic Problems

open access: yes, 2014
How can one construct synoptic hypotheses, always aware both of the many gaps in our knowledge and the theological and historical entailments in any given hypothesis? In his essays John S. Kloppenborg insists that the literature, thought and practices of the early Jesus movement must be treated with a deep awareness of their social, literary, and ...

Main‐chain polyfullerenes: Taking fullerene to the next dimension

open access: yesPolymer International, EarlyView.
This short review appraises main‐chain polyfullerenes. Their slow development over 30 years has suddenly boomed with a rapid growth due to exciting developments in solar energy. Abstract This mini‐review gives an overview of the development, chemistry, properties and applications of main‐chain polyfullerenes.

EnKF and expectation‐maximization based parameter estimation of a convective gravity‐wave parameterization using Strateole 2 constant‐level balloon data

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
An offline methodology is applied to estimate parameters of a convective gravity‐wave scheme using momentum flux (MF) observations from constant‐level balloons (left panels: pdfs of east and west MFs in green from observations and black from EnKF). The approach integrates an ensemble Kalman filter with an expectation‐maximization algorithm and permits ...
