Shadowgraphy is a technique widely used to diagnose objects or systems in various fields in physics and engineering. In shadowgraphy, an optical beam is deflected by the object and then the intensity modulation is captured on a screen placed some distance away. However, retrieving quantitative information from the shadowgrams themselves is a challenging task because of the nonlinear nature of the process. Here, we present a method to retrieve quantitative information from shadowgrams, based on…

Retrieving fields from proton radiography without source profiles.
This paper presents a statistical method to retrieve the integrated field from the modulated intensity profile without needing to know the exact source profile, and applies this method to experimental data, showing the robustness of the approach.
Reconstructing magnetic deflections from sets of proton images using differential evolution.
A new method for reconstructing the path-integrated magnetic fields, which begins to address the problem posed by caustics, and requires no assumption of deflection linearity and can reliably solve for fields underlying linear, nonlinear, and caustic proton image features for the selected geometries.

Recent laser-plasma experiments (Fox et al., Phys. Rev. Lett., vol. 111, 2013, 225002; Huntington et al., Nat. Phys., vol. 11(2), 2015, 173–176; Tzeferacos et al., Phys. Plasmas, vol. 24(4), 2017a,
Implementation of a Faraday rotation diagnostic at the OMEGA laser facility
Magnetic field measurements in turbulent plasmas are often difficult to perform. Here we show that for ${\geqslant}$ kG magnetic fields, a time-resolved Faraday rotation measurement can be made at
Mapping the self-generated magnetic fields due to thermal Weibel instability
Weibel-type instability can self-generate and amplify magnetic fields in both space and laboratory plasmas with temperature anisotropy. The electron Weibel instability has generally proven more
Experimental observations of detached bow shock formation in the interaction of a laser-produced plasma with a magnetized obstacle
The magnetic field produced by planets with active dynamos, like the Earth, can exert sufficient pressure to oppose supersonic stellar wind plasmas, leading to the formation of a standing bow shock
Preparations for a European R&D roadmap for an inertial fusion demo reactor
A brief overview of activities, presented here, along with new calculations relates the concept of auxiliary heating of inertial fusion targets, and provides possible future directions of research and development for the updated European Roadmap that is due at the end of 2020.
The Voronoi theory of the normal liver lobular architecture and its applicability in hepatic zonation
Evidence is presented that Voronoi diagrams represent the basis of the two-dimensional organization of the normal liver and that this concept may have wide applicability in liver pathology and research.

CACM is really essential reading for students, it keeps tabs on the latest in computer science and is a valuable asset for us students, who tend to delve deep into a particular area of CS and forget everything that is happening around us.
