Phylogenomics and a posteriori data partitioning resolve the Cretaceous angiosperm radiation Malpighiales [PDF]

Proceedings of the National Academy of Sciences, 2012
The angiosperm order Malpighiales includes ∼16,000 species and constitutes up to 40% of the understory tree diversity in tropical rain forests. Despite remarkable progress in angiosperm systematics during the last 20 y, relationships within Malpighiales remain poorly resolved, possibly owing to its rapid rise during the mid-Cretaceous.

Quantum Barnes Function as the Partition Functionof the Resolved Conifold [PDF]

International Journal of Mathematics and Mathematical Sciences, 2008
We give a short new proof of large N duality between the Chern‐Simons invariants of the 3‐sphere and the Gromov‐Witten/Donaldson‐Thomas invariants of the resolved conifold. Our strategy applies to more general situations, and it is to interpret the Gromov‐Witten, the Donaldson‐Thomas, and the Chern‐Simons invariants as different characterizations of ...

By dawn or dusk—how circadian timing rewrites bacterial infection outcomes

FEBS Letters, EarlyView.
The circadian clock shapes immune function, yet its influence on infection outcomes is only beginning to be understood. This review highlights how circadian timing alters host responses to the bacterial pathogens Salmonella enterica, Listeria monocytogenes, and Streptococcus pneumoniae revealing that the effectiveness of immune defense depends not only

Simulating the Greenland ice sheet under present-day and palaeo constraints including a new discharge parameterization [PDF]

The Cryosphere, 2015
In this paper, we propose a new sub-grid scale parameterization for the ice discharge into the ocean through outlet glaciers and inspect the role of different observational and palaeo constraints for the choice of an optimal set of model parameters. This

Interplay between circadian and other transcription factors—Implications for cycling transcriptome reprogramming

FEBS Letters, EarlyView.
This perspective highlights emerging insights into how the circadian transcription factor CLOCK:BMAL1 regulates chromatin architecture, cooperates with other transcription factors, and coordinates enhancer dynamics. We propose an updated framework for how circadian transcription factors operate within dynamic and multifactorial chromatin landscapes ...

New equation to predict size-resolved gas-particle partitioning quotients for polybrominated diphenyl ethers [PDF]

Journal of Hazardous Materials, 2020
Gas/particle (G/P) partition quotients of semi-volatile organic compounds (SVOCs) for bulk air have been widely discussed in experimental and theoretical contexts, but research on size-resolved G/P partition quotients (KPi) are scarce and limited in scope.

Disordered but rhythmic—the role of intrinsic protein disorder in eukaryotic circadian timing

FEBS Letters, EarlyView.
Unstructured domains known as intrinsically disordered regions (IDRs) are present in nearly every part of the eukaryotic core circadian oscillator. IDRs enable many diverse inter‐ and intramolecular interactions that support clock function. IDR conformations are highly tunable by post‐translational modifications and environmental conditions, which ...
