An iterative method to deconvolve coded-mask images [PDF]

, 2011
Efficent astronomical imaging at energy greater than 20 keV is mainly achieved through modulation, either time (i.e. HXMT) or spatial (i.e. IBIS/INTEGRAL), techniques.

The nulling interferometry data standard: NIFITS

Astronomy & Astrophysics
Aims. The proliferation and scientific impact of optical interferometers in the past 15 years were made possible by the adoption of OIFITS, a standard format for exchanging optical interferometry data.

Single‐molecule DNA flow‐stretch assays for high‐throughput DNA–protein interaction studies

FEBS Open Bio, EarlyView.
We describe an optimised single‐molecule DNA flow‐stretch assay that visualises DNA–protein interactions in real time. Linear DNA fragments are tethered to a surface and stretched by buffer flow for fluorescence imaging. Using λ and φX174 DNA, this protocol enhances reproducibility and accessibility, providing a versatile approach for studying diverse ...

Determining the dimensionality of bipartite orbital-angular-momentum entanglement using multi-sector phase masks [PDF]

, 2012
The Shannon dimensionality of orbital-angular-momentum (OAM) entanglement produced in spontaneous parametric down-conversion can be probed by using multi-sector phase analysers [1].

Using high angular resolution diffusion imaging data to discriminate cortical regions.

PLoS ONE, 2013
Brodmann's 100-year-old summary map has been widely used for cortical localization in neuroscience. There is a pressing need to update this map using non-invasive, high-resolution and reproducible data, in a way that captures individual variability.
