Compressed sensing, image reconstruction and limited measurements

Beyond its theoretical contribution, this work also has signi cant practical impact. It provides new and important insight into how to adapt and optimize the performance of compressed sensing in practical applications. It introduces a new generation of sampling strategies based on multilevel random sampling which are both theoretically optimal and outperform previous state-of-the-art approaches in practice. It has led to new approaches in MRI, NMR, uorescence microscopy and helium atom scattering which offer signi cant performance gains.

Displacement convexity for the entropy in semi-discrete non-linear Fokker-Planck equations

In the year 1781 the problem of optimal transport was first formally discussed by the French mathematician Gaspard Monge. The major point in this field is the task of transforming a probability measure into another one in the way that consumes least energy.…

How to make the data and code for your manuscript available to peer reviewers ‘before’ making it public

It’s no surprise to any internet user that the way we communicate is rapidly changing. For example, in the distant past, we learned the news of the world by reading a few paragraphs of tiny text in hard copies of newspapers.…

Watch: Levitating Objects on an Air Table

Air-tables create a thin film of air capable of supporting objects and causing them to levitate. By adding grooves to the table or the object, Professor John Hinch at the University of Cambridge was able to control the objects motion and describe the resultant acceleration in terms of a simple scaling relationship involving gravity and the aspect ratio.…

Parasitological research in the molecular age

The latest Paper of the Month for Parasitology is ‘Parasitological research in the molecular age‘ by Christian Selbach, Fátima Jorge, Eddy Dowle & Robert Poulin Technological developments often provide new tools for scientific advances.…

John Locke and the Toleration of Catholics: A New Manuscript

Our article investigates the provenance and significance of the manuscript, showing how its content reveals that Locke is commenting on a book by Sir Charles Wolseley (1629/30-1714) called Liberty of conscience, the magistrates interest (1668), as a way of asking whether Catholics can be tolerated.

mm-Wave Research in Nanoscale Communication Integrated Circuits (NCIC) Labs

I was obviously intrigued to be part of this team [of authors], as there was no question in my mind that Ali [Niknejad] and Gernot [Hueber] will be doing a great job in terms of organizing an effort to create the first book on millimeter-wave circuits for 5G applications

Watch: How do Insects Walk on Water?

Using the surface tension of water and a hydrophobic coating on their legs, many insects are able to walk on water.…

On the Cover of HPL: Bremsstrahlung emission from high power laser interactions with constrained targets for industrial radiography

Due to the range of size, density, and resolution demands associated with industrial X-ray radiography, there is not a source that is “one-size fits all”... Altering the source characteristics to deliver what is needed requires continued study. This publication explores the X-ray emission from spatially constrained targets compared to standard foil targets. The research results are published in High Power Laser Science and Engineering, Volume 7, No. 2, 2019 (Armstrong, C. D. , et al. Bremsstrahlung emission from high power laser interactions with constrained targets for industrial radiography.)

The Rumen: Fantastic bugs and where to find them

The animal article of the month for September is 'Invited review: Application of meta-omics to understand the dynamic nature of the rumen microbiome and how it responds to diet in ruminants' Demand for meat and milk is predicted to double by 2050 and meeting this increased demand represents a “grand challenge for humanity”. Ruminants are among the most widely adapted livestock on earth, inhabiting outdoor environments from the arctic to the tropics.

Watch: How do Bubbles Freeze?

Freezing bubbles are not only beautiful, but also demonstrate incredibly complex physics. Here, Professor Jonathan Boreyko explains how bubbles freeze with examples of slow motion videos filmed in his laboratory at Virginia Tech.…

Draft Treaty on business and human rights: a digital environment perspective

On July 16, 2019, the UN open-ended intergovernmental working group on transnational corporations and other business enterprises with respect to human rights (the “Working Group”) published a revised draft of a binding treaty on business and human rights.…
