Accurate cosmic shear errors: do we need ensembles of simulations? [PDF]

open access: yes, 2018
Accurate inference of cosmology from weak lensing shear requires an accurate shear power spectrum covariance matrix. Here, we investigate this accuracy requirement and quantify the relative importance of the Gaussian (G), super-sample covariance (SSC ...

Mass Spectrometry Structural Proteomics Enabled by Limited Proteolysis and Cross‐Linking

open access: yesMass Spectrometry Reviews, EarlyView.
ABSTRACT The exploration of protein structure and function stands at the forefront of life science and represents an ever‐expanding focus in the development of proteomics. As mass spectrometry (MS) offers readout of protein conformational changes at both the protein and peptide levels, MS‐based structural proteomics is making significant strides in the

Dynamic Package Interfaces - Extended Version

open access: yes, 2013
A hallmark of object-oriented programming is the ability to perform computation through a set of interacting objects. A common manifestation of this style is the notion of a package, which groups a set of commonly used classes together.

Calcium signaling in plant defense

open access: yesNew Plant Protection, EarlyView.
Calcium signaling acts as a central hub in plant immunity, translating pathogen perception into defense responses. This review highlights the channels, sensors, and signaling networks involved, and discusses how pathogens subvert calcium dynamics, as well as how this knowledge may inspire innovative strategies for engineering durable crop resistance ...
