This line of mirrors, available in sizes from 18.7 to 74.8 inches, enables safety professionals to guard multiple sides of a work cell using only one emitter/receiver pair.

The results of a study of the structural and reflective characteristics of short-period multilayer X-ray mirrors based on Mo/B4C at wavelengths 1.54 Å, 9.89 Å and 17.59 Å are presented. The period of the samples varied in the range 8–35 Å. The average widths of the interfaces were ∼3.5 and 2.2 Å at one and the other boundaries, with a tendency for weak growth with any decrease in the period. The interlayer roughness was ∼1 Å. The research results indicate promising prospects for the use of multilayer Mo/B4C mirrors for synchrotron applications.

Synchrotron light sources require X-ray optics with extremely demanding accuracy for the surface profile, with less than 100 nrad slope errors and sub-nanometre height errors. Such errors are challenging to achieve for aspheres using traditional polishing methods. However, post-polishing error correction can be performed using techniques such as ion beam figuring (IBF) to improve optics to the desired quality. This work presents a brief overview of the history of IBF, introduces some of the challenges for obtaining such demanding figure errors, and highlights the work done at several in-house IBF facilities at synchrotron light sources worldwide to obtain state-of-the-art optical quality.

Ion beam figuring (IBF) is a powerful technique for figure correction of X-ray mirrors to a high accuracy. Here, recent technical advancements in the IBF instrument developed at Diamond Light Source are presented and experimental results for figuring of X-ray mirrors are given. The IBF system is equipped with a stable DC gridded ion source (120 mm diameter), a four-axis motion stage to manipulate the optic, a Faraday cup to monitor the ion-beam current, and a camera for alignment. A novel laser speckle angular measurement instrument also provides on-board metrology. To demonstrate the IBF system's capabilities, two silicon X-ray mirrors were processed. For 1D correction, a height error of 0.08 nm r.m.s. and a slope error of 44 nrad r.m.s. were achieved. For 2D correction over a 67 mm × 17 mm clear aperture, a height error of 0.8 nm r.m.s. and a slope error of 230 nrad r.m.s. were obtained. For the 1D case, this optical quality is comparable with the highest-grade, commercially available, X-ray optics.

Modeling the behavior of a prototype cantilevered X-ray adaptive mirror (held from one end) demonstrates its potential for use on high-performance X-ray beamlines. Similar adaptive mirrors are used on X-ray beamlines to compensate optical aberrations, control wavefronts and tune mirror focal distances at will. Controlled by 1D arrays of piezoceramic actuators, these glancing-incidence mirrors can provide nanometre-scale surface shape adjustment capabilities. However, significant engineering challenges remain for mounting them with low distortion and low environmental sensitivity. Finite-element analysis is used to predict the micron-scale full actuation surface shape from each channel and then linear modeling is applied to investigate the mirrors' ability to reach target profiles. Using either uniform or arbitrary spatial weighting, actuator voltages are optimized using a Moore–Penrose matrix inverse, or pseudoinverse, revealing a spatial dependence on the shape fitting with increasing fidelity farther from the mount.

What would it take to turn Texas, a Republican stronghold, into a blue state? According to data from SurveyMonkey, just remove all the gun owners from the Lone Star State and it would have gone to Hillary Clinton in 2016. You can do the same thing in liberal California. Remove all the non-gun owners and the state would have voted for Donald Trump.

That’s how divisive the issue of gun control is in American politics.

SurveyMonkey found that no other demographic — not race, religion or gender — so perfectly divided voters. In the 2016 election, 47 percent of Trump supporters said gun control was an issue important enough to influence their vote. That’s compared to just 27 percent of voters who supported Hillary Clinton.

But what does this divide mean? How is it impacting gun control policy, and how might this issue change in light of recent mass shootings like Las Vegas, Orlando and Newtown? To discuss the data, join a PBS NewsHour-hosted Twitter chat at 1 p.m. EDT Thursday with data journalist Dante Chinni (@Dchinni), professor and chairman of political science at the University of Kansas Don Haider-Markel (@dhmarkel), and Washington Post correspondent Philip Bump (@pbump).

An equatorial sundial apparatus with an adjustable base assembly utilizing one or more concave cylindrical focusing mirrors. One of the benefits that is derived from this apparatus is the use of one or more concave cylindrical mirrors to project a focused beam of light onto a calibrated surface from which the time can be read. This sundial has the additional benefit of not suffering from blurring of the time indicator in a shadow or non-focused beam of light typical of other sundials. This sundial's focused light forms a sharply demarcated indicator from which time can be read to the minute. A further benefit of this apparatus is the ability to incorporate multiple concave cylindrical focusing mirrors to reduce the size of the visual field or screen where the time is read and to incorporate various shapes and designs for ornamental purposes without significant compromise of the sundials accuracy for telling time. An additional benefit of this apparatus is the ability to quickly, accurately and easily adjust the apparatus to the proper tilt upon setup according to the latitude where it will be located by means of an adjustable base assembly.

Implementing a layered hyperbolic metamaterial in a vertical cavity surface emitting laser (VCSEL) to improve thermal conductivity and thermal dissipation thereby stabilizing optical performance. Improvement in the thermal management and power is expected by replacing the distributed Bragg reflector (DBR) mirrors in the VCSEL. The layered metamaterial structure performs the dual function of the DBR and the heat spreader at the same time.

System for establishing a surface shape. The system includes a compliant substrate including the surface and having a reverse side, and a plurality of discrete actuators engaging the reverse side and arranged in a selected pattern to control the surface shape as individual discrete activators are activated. It is preferred that the actuators have multiple discrete stable states of elongation. A particularly preferred embodiment uses actuators that are binary with two stable states of elongation.

I have watched everything that was pending on my must-watch list over the years," laughs Tahir Raj Bhasin, echoing the sentiment of many who have turned to digital entertainment to escape the lockdown ennui. A movie aficionado, the actor has been making the most of the stay-at-home period by acquainting himself with the works of the masters — from Russian director Andrei Tarkovsky to Oscar-winner Bong Joon-ho."

"My first recommendation would be Shoplifters on Netflix. It's a 2018 Japanese drama by Hirokazu Koreeda that traces the story of a dysfunctional family. It has a slow pace, but the lockdown is the perfect time to widen your horizon when it comes to movie consumption," says Bhasin. For those fascinated by crime thrillers like he is, the actor has a suggestion. "The 2002 HBO series, The Wire, was the first show that I had binged on. It was the first time that film budgets [were commissioned] for long-format storytelling on television, making it a path-breaking series. Being a fan of House of Cards, I revisited Borgen, the Danish political thriller that is said to be the inspiration for the American drama. I also relished the animation series, Love Death + Robots."

A still from Stalker

The movie that left an indelible impact on his mind was Tarkovsky's sci-fi offering, Stalker (1979). "It's available on YouTube. In Stalker, Tarkovsky is talking about an apocalyptic world where there are few human beings around and they have to stay away from each other. I was able to relate to it as it almost mirrors our current situation."
