Soft X-ray varied-line-spacing gratings fabricated by near-field holography using an electron beam lithography-written phase mask

A fabrication method comprising near-field holography (NFH) with an electron beam lithography (EBL)-written phase mask was developed to fabricate soft X-ray varied-line-spacing gratings (VLSGs). An EBL-written phase mask with an area of 52 mm × 30 mm and a central line density greater than 3000 lines mm−1 was used. The introduction of the EBL-written phase mask substantially simplified the NFH optics for pattern transfer. The characterization of the groove density distribution and diffraction efficiency of the fabricated VLSGs indicates that the EBL–NFH method is feasible and promising for achieving high-accuracy groove density distributions with corresponding image properties. Vertical stray light is suppressed in the soft X-ray spectral range.

The crystal structure of the zwitterionic co-crystal of 2,4-di­chloro-6-{[(3-hy­droxy­prop­yl)azaniumyl]­meth­yl}phenolate and 2,4-di­chloro­phenol

The title compound, C10H13Cl2NO2·C6H4Cl2O, was formed from the incomplete Mannich condensation reaction of 3-amino­propan-1-ol, formaldehyde and 2,4-di­chloro­phenol in methanol. This resulted in the formation of a co-crystal of the zwitterionic Mannich base, 2,4-di­chloro-6-{[(3-hy­droxy­prop­yl)azaniumyl]­meth­yl}phenolate and the unreacted 2,4-di­chloro­phenol. The compound crystallizes in the monoclinic crystal system (in space group Cc) and the asymmetric unit contains a mol­ecule each of the 2,4-di­chloro­phenol and 2,4-di­chloro-6-{[(3-hy­droxy­prop­yl)azaniumyl]­meth­yl}phenolate. Examination of the crystal structure shows that the two components are clearly linked together by hydrogen bonds. The packing patterns are most inter­esting along the b and the c axes, where the co-crystal in the unit cell packs in a manner that shows alternating aromatic di­chloro­phenol fragments and polar hydrogen-bonded channels. The 2,4-di­chloro­phenol rings stack on top of one another, and these are held together by π–π inter­actions. The crystal studied was refined as an inversion twin.

Namdinator – automatic molecular dynamics flexible fitting of structural models into cryo-EM and crystallography experimental maps

Model building into experimental maps is a key element of structural biology, but can be both time consuming and error prone for low-resolution maps. Here we present Namdinator, an easy-to-use tool that enables the user to run a molecular dynamics flexible fitting simulation followed by real-space refinement in an automated manner through a pipeline system. Namdinator will modify an atomic model to fit within cryo-EM or crystallography density maps, and can be used advantageously for both the initial fitting of models, and for a geometrical optimization step to correct outliers, clashes and other model problems. We have benchmarked Namdinator against 39 deposited cryo-EM models and maps, and observe model improvements in 34 of these cases (87%). Clashes between atoms were reduced, and the model-to-map fit and overall model geometry were improved, in several cases substantially. We show that Namdinator is able to model large-scale conformational changes compared to the starting model. Namdinator is a fast and easy tool for structural model builders at all skill levels. Namdinator is available as a web service (https://namdinator.au.dk), or it can be run locally as a command-line tool.

Pressure-induced transformation of CH3NH3PbI3: the role of the noble-gas pressure transmitting media

The photovoltaic perovskite, methyl­ammonium lead triiodide [CH3NH3PbI3 (MAPbI3)], is one of the most efficient materials for solar energy conversion. Various kinds of chemical and physical modifications have been applied to MAPbI3 towards better understanding of the relation between composition, structure, electronic properties and energy conversion efficiency of this material. Pressure is a particularly useful tool, as it can substantially reduce the interatomic spacing in this relatively soft material and cause significant modifications to the electronic structure. Application of high pressure induces changes in the crystal symmetry up to a threshold level above which it leads to amorphization. Here, a detailed structural study of MAPbI3 at high hydro­static pressures using Ne and Ar as pressure transmitting media is reported. Single-crystal X-ray diffraction experiments with synchrotron radiation at room temperature in the 0–20 GPa pressure range show that atoms of both gaseous media, Ne and Ar, are gradually incorporated into MAPbI3, thus leading to marked structural changes of the material. Specifically, Ne stabilizes the high-pressure phase of NexMAPbI3 and prevents amorphization up to 20 GPa. After releasing the pressure, the crystal has the composition of Ne0.97MAPbI3, which remains stable under ambient conditions. In contrast, above 2.4 GPa, Ar accelerates an irreversible amorphization. The distinct impacts of Ne and Ar are attributed to differences in their chemical reactivity under pressure inside the restricted space between the PbI6 octahedra.

Measurement of the horizontal beam emittance of undulator radiation by tandem-double-slit optical system

A tandem-double-slit optical system was constructed to evaluate the practical beam emittance of undulator radiation. The optical system was a combination of an upstream slit (S1) and downstream slit (S2) aligned on the optical axis with an appropriate separation. The intensity distribution after the double slits, I(x1, x2), was measured by scanning S1 and S2 in the horizontal direction. Coordinates having 1/sqrt e intensity were extracted from I(x1, x2), whose contour provided the standard deviation ellipse in the x1–x2 space. I(x1, x2) was converted to the corresponding distribution in the phase space, I(x1, x1'). The horizontal beam emittance was evaluated to be 3.1 nm rad, which was larger than the value of 2.4 nm rad estimated by using ray-tracing. It was found that the increase was mainly due to an increase in beam divergence rather than size.

Fast fitting of reflectivity data of growing thin films using neural networks

X-ray reflectivity (XRR) is a powerful and popular scattering technique that can give valuable insight into the growth behavior of thin films. This study shows how a simple artificial neural network model can be used to determine the thickness, roughness and density of thin films of different organic semiconductors [diindenoperylene, copper(II) phthalocyanine and α-sexithiophene] on silica from their XRR data with millisecond computation time and with minimal user input or a priori knowledge. For a large experimental data set of 372 XRR curves, it is shown that a simple fully connected model can provide good results with a mean absolute percentage error of 8–18% when compared with the results obtained by a genetic least mean squares fit using the classical Parratt formalism. Furthermore, current drawbacks and prospects for improvement are discussed.

BornAgain: software for simulating and fitting grazing-incidence small-angle scattering

BornAgain is a free and open-source multi-platform software framework for simulating and fitting X-ray and neutron reflectometry, off-specular scattering, and grazing-incidence small-angle scattering (GISAS). This paper concentrates on GISAS. Support for reflectometry and off-specular scattering has been added more recently, is still under intense development and will be described in a later publication. BornAgain supports neutron polarization and magnetic scattering. Users can define sample and instrument models through Python scripting. A large subset of the functionality is also available through a graphical user interface. This paper describes the software in terms of the realized non-functional and functional requirements. The web site https://www.bornagainproject.org/ provides further documentation.

Structure-mining: screening structure models by automated fitting to the atomic pair distribution function over large numbers of models

A new approach is presented to obtain candidate structures from atomic pair distribution function (PDF) data in a highly automated way. It fetches, from web-based structural databases, all the structures meeting the experimenter's search criteria and performs structure refinements on them without human intervention. It supports both X-ray and neutron PDFs. Tests on various material systems show the effectiveness and robustness of the algorithm in finding the correct atomic crystal structure. It works on crystalline and nanocrystalline materials including complex oxide nanoparticles and nanowires, low-symmetry and locally distorted structures, and complicated doped and magnetic materials. This approach could greatly reduce the traditional structure searching work and enable the possibility of high-throughput real-time auto-analysis PDF experiments in the future.

The Academy Awards have made history with breakthroughs for minorities in the past — but with this year's nominations, observers are noting how white the Oscars are, with no actors of color nominated in any of this year's acting categories.

It marks the least diverse nominations since 1998. People have been speaking out about this disconnect, with films like "Selma" being shut out of the acting nominations (though it did pick up a Best Picture nomination).

Mike Roe with Jennifer Velez

Harris Wittels, a comedy writer who worked on "Parks & Recreation," has died at 30, the Los Angeles Police Department's Jane Kim tells KPCC.

Wittels was discovered by his assistant around 12 p.m., Kim said, and was already dead. Kim said that Wittels' death was a possible overdose, but that the Coroner's Office would determine the cause of death. Wittels had attended drug rehab twice.

Comedy Central, where Wittels worked on "The Sarah Silverman Program" and "Secret Girlfriend," confirmed Wittels' death, as did the comedy show he appeared at Wednesday night.

Comedy Central tweet

Meltdown Show tweet

Wittels was also well known for his @Humblebrag Twitter account and later book, helping to popularize the idea online of the false modesty of bragging while trying not to look like you're bragging.

Wittels had spoken about his struggles with addiction in places including Pete Holmes's podcast "You Made It Weird" in a November episode.

"I just really stopped caring about my life," Wittels said on "You Made It Weird," explaining how he got into doing drugs. "I just really started to think, well, if I'm only here for 80 years, then who cares if I spend it high or not?"

Wittels received his first big break when Sarah Silverman saw him performing comedy and gave him a job writing for her Comedy Central show.

Wittels also wrote for HBO's "Eastbound & Down," several MTV awards shows and the American Music Awards. He had a recurring role on "Parks & Recreation" and was a regular guest on the "Comedy Bang Bang" podcast.

Comedians, actors and fans mourned Wittels' death online.

'Ready Player One' was written using cheat codes — here are our 11 favorites

A Nintendo Entertainment System.; Credit: Mark Ramsay/Flickr Creative Commons

Mike Roe

There have been plenty of video game movies over the years, but there have been far fewer actually good ones. "Ready Player One," based on the 2011 video game-inspired novel, has the chance to be a great one thanks to the announcement that Steven Spielberg has signed on to direct.

That book was inspired by classic video games, and was written using classic video game cheats to play parts of classic games and write them into his book, author Ernest Cline said in a recent talk. That got us thinking about the classic video game cheats and secrets that stuck with us from our younger days playing classic video games — here's our top 11.

1. The Konami Code

Up up down down left right left right B A start! This code became such a part of video game culture that it got its own name. It was popularized in various games made by Konami, particularly Contra, leading to it also being known as the "Contra Code" for its ability to give you 30 lives in the game. Before the Internet, it was spread through gaming magazines and word of mouth — it was so influential that there are still developers who put it in their games. (There's even an entire Wikipedia page of games, both from Konami and others, that use the Konami Code. It's even been used on some websites.)

What is the Konami Code

2. Street Figher II Turbo's turbo

The game that I actually used a code for the most as a kid, the Super Nintendo code down, R, up, L, Y, B on the second controller didn't give you any advantages — it just kicked the speed up. By default, you had a few selections for how fast the game would be, but you could multiple that several-fold with this code, letting you and your friends battle at what at the time felt unbelievably fast.

3. Super Mario Bros.'s Minus World

This one doesn't involve a code, but players managed to discover what was deemed a glitch in the game that put you into a messed up version of another level, dubbed by fans the Minus World due to just "-1" instead of a full level number appearing at the top of the screen. There was no way to escape the glitched level, no matter how hard you might try, sending you to play it over and over again until your time ran out or you were killed by enemies. Still, modern players have found that you can go on thanks to various computer emulators and the like; see some of the worlds beyond below:

Minus World video

4. Metroid and Justin Bailey

Fans early on discovered that the password JUSTIN BAILEY allowed you to start with all of the available weapons along with plenty of life and ammo. Fans didn't know whether Justin Bailey was a reference to an actual person, just a code coincidence or something else, but that didn't stop them from eagerly playing through with this code. It also removed lead character Samus Aran from her armor, allowing players to discover that the game's star was an early female lead character, even if her armor didn't clue players in before the end of the game without the code.

Justin Bailey video

5. Doom's God mode

By typing the letters iddqd in PC game Doom, players could enable God mode, making them essentially invincible and letting them power through the early first-person shooter. The code had been available in developer id's earlier game Wolfenstein, but hadn't been quite as easily accessible. So, if you ever need a power boost when you're fighting on Mars, Doom has the answer. (Unfortunately, we don't believe this provides any extra protection for NASA's Mars rovers.)

6. Mortal Kombat's Reptile

The developers of Mortal Kombat made a battle against Reptile unbelievably hard for Mortal Kombat fans, including putting some randomness into whether doing what you were supposed to do to unlock the character would even work. Still, players happily pumped in extra quarters for the chance to face off against Reptile, a character with a look that mirrored that of characters Sub-Zero and Scorpion, just with a different color. Players had to achieve a Double Flawless victory on the Pit level, finish the match using their fatality move, and there also had to be a silhouette flying past the moon in the background — which only happened every sixth game.

Mortal Kombat: Reptile

7. The Legend of Zelda's Second Quest

The Legend of Zelda was a pretty challenging early adventure game, one of the first releases for the Nintendo home video game console. When you beat the game, you were given the option to go on a "Second Quest," which was a tweaked version of the game you just played except waaaaay harder. However, if you thought you were the coolest kid on the block and were so awesome you didn't need a warmup, you could name your character "ZELDA" (in one of the more obvious cheats in video game history) and skip ahead to that Second Quest from the start. You would then likely cry from how hard it was and start another new game with a different name.

8. NBA Jam's celebrity secret characters

A variety of celebrities from sports, music, and even politics were available by putting in various initials combined with buttons on the controller. These included then-President Bill Clinton, Al Gore, Warren Moon and more. That tradition has been continued in more recent NBA Jam games, with President Obama and others available for your video gaming pleasure.

9. GoldenEye's extra modes

There were a wide variety of cheat codes for GoldenEye, widely considered one of the all-time great first-person shooters. Sure, you could use codes to unlock different levels, but the reason these codes are remembered is because it gave you all sorts of new ways to play against your friends. The game also had an actual cheat menu that would appear if you accomplished one of a variety of goals, and from that menu you could cheat extra hard by using your controller to unlock things like a paintball mode, turbo mode, modes with both giant heads and teeny-tiny James Bonds and more.

10. Sonic The Hedgehog 2's Debug Mode

The Sonic debug mode is the perfect example of why so many games included cheats back in the day: They were often for the developers to be able to more easily play the games while looking for bugs and doing other testing. Sonic 2 let you get to an actual debug mode by playing various sounds from the level select screen (1, 9, 9, 2, 1, 1, 2, 4, for your reference), then pressing start and holding the A button. Developers later put them in for fun and intended them for the players to discover, but some of the early cheat codes were just meant for developers — but players proved more intrepid than they may have anticipated.

Sonic debug mode

11. Mike Tyson's Punch-Out: Go straight to Mike Tyson

There was actually a password mode in this game — before games had the option to save, plenty of games gave you codes that let you get back to where you were before. This is one of the examples from that darker time, where whether you played through opponents like Glass Joe and Bald Bull or not, you could try your changes against Lightning Mike (at least until the video game's license ran out and he was replaced in future editions with the way less exciting "Mr. Dream"). You better have had a pen and paper ready when your friend started yelling at you 007 373 5963 for you to use on your own copy of the game — no sharing. The game is hard enough that even Mike Tyson had some trouble fighting himself:

Mike Tyson vs. Mike Tyson

Let us know in the comments the classic video games — and the classic cheat codes and secrets — that inspired you.
