The report of the Executive Committee for 2017 is presented.

This work considers the scaling properties characterizing the hyperuniformity (or anti-hyperuniformity) of long-wavelength fluctuations in a broad class of one-dimensional substitution tilings. A simple argument is presented which predicts the exponent α governing the scaling of Fourier intensities at small wavenumbers, tilings with α > 0 being hyperuniform, and numerical computations confirm that the predictions are accurate for quasiperiodic tilings, tilings with singular continuous spectra and limit-periodic tilings. Quasiperiodic or singular continuous cases can be constructed with α arbitrarily close to any given value between −1 and 3. Limit-periodic tilings can be constructed with α between −1 and 1 or with Fourier intensities that approach zero faster than any power law.

The crystal structure of tri­phenyl­methanol, C19H16O, has been redetermined using data collected at 295 and 153 K, and is compared to the model published by Ferguson et al. over 25 years ago [Ferguson et al. (1992). Acta Cryst. C48, 1272–1275] and that published by Serrano-González et al., using neutron and X-ray diffraction data [Serrano-González et al. (1999). J. Phys. Chem. B, 103, 6215–6223]. As predicted by these authors, the hy­droxy groups are involved in weak inter­molecular hydrogen bonds in the crystal, forming tetra­hedral tetra­­mers based on the two independent mol­ecules in the asymmetric unit, one of which is placed on the threefold symmetry axis of the Roverline{3} space group. However, the reliable determination of the hy­droxy H-atom positions is difficult to achieve, for two reasons. Firstly, a positional disorder affects the full asymmetric unit, which is split over two sets of positions, with occupancy factors of ca 0.74 and 0.26. Secondly, all hy­droxy H atoms are further disordered, either by symmetry, or through a positional disorder in the case of parts placed in general positions. We show that the correct description of the hydrogen-bonding scheme is possible only if diffraction data are collected at low temperature. The pro­chiral character of the hydrogen-bonded tetra­meric supra­molecular clusters leads to enanti­omorphic three-dimensional graphs in each tetra­mer. The crystal is thus a racemic mixture of supS and supR motifs, consistent with the centro­symmetric nature of the Roverline{3} space group.

The enanti­opure monopyrrolidine derivative (2S)-methyl (Z)-5-(2-tert-but­oxy-1-cyano-2-oxo­ethyl­idene)pyrrolidine-2-carboxyl­ate, C13H18N2O4, (1), represents a potential ligand and an attractive inter­mediate for the synthesis of chiral metal com­plexes. At the mol­ecular level, the com­pound features an intra­molecular N—H⋯O hydrogen bond; neighbouring mol­ecules inter­act via N—H⋯N contacts to form chains along [100]. Due to its elemental com­position, resonant scattering of the target com­pound is entirely insignificant for diffraction experiments with Mo Kα and small even for Cu Kα radiation. A preliminary study with the harder radiation type confirmed the chiral space group and the suitability of the single crystal chosen; as expected, the results concerning the absolute structure remained com­pletely inconclusive. A second data collection with the longer wavelength gave satisfactory quality indicators for the correct handedness of the mol­ecule, albeit with high standard uncertainties. The absolute configuration has been assessed independently: CD spectra for both enanti­omers of the target mol­ecule were calculated and the spectrum for the S-configured stereoisomer was in agreement with the experiment. The Cotton effect of (1) may be ascribed to π–π* transitions from HOMO to LUMO and from HOMO to LUMO+1. As both independent techniques agree with respect to the handedness of the target mol­ecule, the absolute structure may be assigned with a high degree of confidence.

An operationally simple and time-efficient approach has been developed for the synthesis of racemic N-substituted 3-(2-aryl-2-oxoeth­yl)-3-hy­droxy­indolin-2-ones by a piperidine-catalysed aldol reaction between aryl methyl ketones and N-alkyl­isatins. These aldol products were used successfully as strategic inter­mediates for the preparation of N-substituted (E)-3-(2-hetaryl-2-oxo­ethyl­idene)indolin-2-ones by a stereoselective dehydration reaction under acidic conditions. The products have all been fully characterized by 1H and 13C NMR spectroscopy, by mass spectrometry and, for a representative selection, by crystal structure analysis. In each of (RS)-1-benzyl-3-hy­droxy-3-[2-(4-meth­oxy­phen­yl)-2-oxoeth­yl]indolin-2-one, C24H21NO4, (Ic), and (RS)-1-benzyl-3-{2-[4-(di­methyl­amino)­phen­yl]-2-oxoeth­yl}-3-hy­droxy­indolin-2-one, C25H24N2O3, (Id), inversion-related pairs of mol­ecules are linked by O—H⋯O hydrogen bonds to form R22(10) rings, which are further linked into chains of rings by a combination of C—H⋯O and C—H⋯π(arene) hydrogen bonds in (Ic) and by C—H⋯π(arene) hydrogen bonds in (Id). The mol­ecules of (RS)-1-benzyl-3-hy­droxy-3-[2-oxo-2-(pyridin-4-yl)eth­yl]indolin-2-one, C22H18N2O3, (Ie), are linked into a three-dimensional framework structure by a combination of O—H⋯N, C—H⋯O and C—H⋯π(arene) hydrogen bonds. (RS)-3-[2-(Benzo[d][1,3]dioxol-5-yl)-2-oxoeth­yl]-1-benzyl-3-hy­droxy­indolin-2-one, C24H19NO5, (If), crystallizes with Z' = 2 in the space group Poverline{1} and the mol­ecules are linked into com­plex sheets by a combination of O—H⋯O, C—H⋯O and C—H⋯π(arene) hydro­gen bonds. In each of (E)-1-benzyl-3-[2-(4-fluoro­phen­yl)-2-oxo­ethyl­idene]indolin-2-one, C23H16FNO2, (IIa), and (E)-1-benzyl-3-[2-oxo-2-(thiophen-2-yl)ethylidene]indolin-2-one, C21H15NO2S, (IIg), the mol­ecules are linked into simple chains by a single C—H⋯O hydrogen bond, while those of (E)-1-benzyl-3-[2-oxo-2-(pyridin-4-yl)ethyl­idene]indolin-2-one, C22H16N2O2, (IIe), are linked by three C—H⋯O hydrogen bonds to form sheets which are further linked into a three-dimensional structure by C—H⋯π(arene) hydrogen bonds. There are no hydrogen bonds in the structures of either (E)-1-benzyl-3-[2-(4-meth­oxy­phen­yl)-2-oxo­ethyl­idene]indolin-2-one, C24H19NO3, (IIc), or (E)-1-benzyl-5-chloro-3-[2-(4-chloro­phen­yl)-2-oxo­ethyl­idene]indolin-2-one, C23H15Cl2NO2, (IIh), but the mol­ecules of (IIh) are linked into chains of π-stacked dimers by a combination of C—Cl⋯π(arene) and aromatic π–π stacking inter­actions.

Maroon 5 has a new music video built around a simple, viral-bait premise: Adam Levine and the rest of the band trying to crash as many weddings around Los Angeles as they can in one day (Dec. 6 of last year). It's a lot of fun, directed by "Wedding Crashers" movie director David Dobkin, but it appears that some of those "crashed weddings" may have been staged.

Watch the video (warning: contains adult language):

Maroon 5: Sugar

Fans have noticed that several of the couples seen in the video appear to be actors. Actors Stephen and Barbara Woo posted on Facebook that they played the parents of one of the brides in the video and said that not only were the weddings staged, they didn't even take place on one day, claiming that all the weddings were shot in the same location over the course of three days.

Facebook post by actors

The groom from the wedding featured the most in the video has been named by observers as Nico Evers-Swindell, according to Cosmopolitan. Evers-Swindell was already married to actress Megan Ferguson since 2011 — and she's not the "bride" in the video.

Fans have fingered one of the models as "America's Next Top Model" runner-up Raina Hein, according to Cosmopolitan. Also, the man believed to be her long-term boyfriend isn't the groom in the Maroon 5 weddings.

Don't lose heart, though — at least one of the weddings in the video appears to be real, with wedding photographer Duke Khodaverdian telling E! that yes, it was the real deal.

"It was an incredible surprise and everyone at the wedding is going to cherish those memories," Khodaverdian told E! in December.

A representative for the band told "Entertainment Tonight" that only the grooms knew about the band in each case — but it looks like that means in the case of the real crashed weddings. The representative did concede that some shots "had to be shot separately from the real weddings due to time and space constraints that were given," and the article does note that the video was shot over three days.

Levine expressed his excitement about crashing the weddings in an interview with People magazine.

"I had no idea I would be affected by the overwhelming reactions we received from the couples and guests," Levine said. He told "Entertainment Tonight" that it was stressful to arrange, but that the surprise felt good. "[We were] happy that they liked our band, too – [that] would have been a total disaster."

They also solicited Twitter to find people lip-syncing "Sugar" to possibly put in their music video, but it doesn't look like those submissions got used.

Maroon 5 Sugar tweet

If you want to see Levine involved in a different dubious outfit, you can see him back hosting "The Voice" on Feb. 23. Open call auditions for the show begin Jan. 24 in New York, with Los Angeles auditions on Jan. 31 and Feb. 1.

Did you spot any more actors you recognize in this video? Do you have any more evidence of any of these weddings being either real or faked? Let me know on Twitter at @MikeRoe.

A still from "POWER/RANGERS," a highly-produced Power Rangers fan film starring James Van Der Beek and Katee Sackhoff.

Update 2/28: The "POWER/RANGERS" film is back on YouTube and Vimeo. Watch the censored YouTube version with a new viewer discretion disclaimer here:

POWER/RANGERS

You can also watch the Vimeo version, featuring more adult content. The video's description emphasizes its lack of connection in any official way to the Power Rangers:

"Deboot of the Power Rangers. My take on the FAN FILM. Not a pilot, not a series, not for profit, strictly for exhibition. This is a bootleg experiment not affiliated or endorsed by Saban Entertainment or Lionsgate nor is it selling any product. I claim no rights to any of the characters (don't send me any money, not kickstarted, this film is free). This is the NSFW version. An alternate safe version is on youtube."

Director Joseph Kahn tells Deadline, "They put these disclaimers on so kids so don’t confuse our super-violent film with their Power Rangers brand. There are no hard feelings. We signed contracts. We can play it anywhere we want on all platforms. I think they realized that people just want to see it."

Previously: A Power Rangers short film went viral this week, starring Katee Sackhoff (Battlestar Galactica) and James Van Der Beek (Dawson!) in a Tarantino-meets-sci-fi take on a dark future for the formerly Mighty Morphin'.

The company behind the 22-year history of the kids/toy icons issued takedown requests, leading to it being pulled from Vimeo and, on Thursday afternoon, a toned-down version being taken off YouTube. At the time, the video had received over 10 million views. It's still available to watch in this Facebook embed from the producer's Facebook page:

POWER/RANGERS Facebook embed

The film was directed by Joseph Kahn, best known as the music video director behind clips like Taylor Swift's "Blank Space" as well as videos for Britney Spears, U2 and others, and produced by Adi Shankar, who was also behind "The Grey" and "Dredd." Kahn co-wrote the film with Van Der Beek and lesser-known writer Dutch Southern.

This isn't the first quasi-legal fan film produced by Shankar. He's also done the same with Marvel Comics characters the Punisher and Venom. The Punisher film even had one of the actors who played the character on screen, Thomas Jane.

Watch those films (Warning: Adult language and violence):

Punisher short

Venom short

Kahn tells HitFix that Shankar came to him, offering him the chance to reboot an existing property.

One reason for the current legal contentiousness: The Power Rangers are set to hit the big screen next year in a Lionsgate film. Kahn says that, if that film was offered to him, he wouldn't be interested.

"I wouldn't even want to make 'Power Rangers: The Movie' for real," Kahn told HitFix. "Like if I had to make a 'Power Rangers' movie, this is it. It's 14 minutes long, and it's violent, and this is what I have in me. If they offered me the $200 million version, the PG-13 version, I literally wouldn't do it."

There's been a strong response to the video, but the response has been mixed — among the original Power Rangers. The original Green Ranger, actor Jason David Frank, said on Facebook that he was approached to be in the movie but declined. (The film's director denies this claim, saying that Frank must have confused them with another project.) Frank also criticized the adult content.

"I'm just a PG-13 guy," Frank said. "The cuss words, the drugs, all this other stuff, it doesn't fly with me." He says that he thinks the Power Rangers are still connected with kids, and he didn't like the idea of doing a dark and gritty version in that context. (Watch his video below.)

Green Ranger video

But the original Pink Ranger, actress Amy Jo Johnson, gave the film her stamp of approval, which Sackhoff enthusiastically responded to.

Katee Sackhoff tweet

Sackhoff told the Nerdcore Movement site that she loves fan films.

"Doing a fan video is kind of the biggest honor you can give a franchise. It’s something that inspired you so much that you want to create," Sackhoff said.

Kahn defended "POWER/RANGERS" on Twitter as being protected due to it being a satire and also cited fair use laws and free speech. He argued that there are lots of other fan films and pointed out that YouTube showed more leniency, leaving it up.

"Every image in POWER/RANGERS is original footage," Kahn wrote in a series of tweets to Vimeo. "Nothing was pre-existing. There is no copyrighted footage in the short."

He also said that it's being given away for free and that Kahn paid for it himself.

Kahn tweet

"It is just as if I drew a pic of Power Rangers on a napkin and I gave it to my friend," Kahn wrote. "Is it illegal to give pic I drew of a character on a napkin to someone for free? No. The world is watching your actions right now."

In a touch of irony, the video had been selected as a Vimeo staff pick before the service took it down. They also responded to complaints about it being taken down, saying that they had to due to the Digital Millennium Copyright Act, and that they would restore the video immediately if the copyright claim was withdrawn, telling fans to complain to Power Rangers copyright holder Saban.

YouTube tweet

Despite the short film's success, hardcore Power Rangers fans are less sure about it, Shamus Kelley tells KPCC. Kelley created his own Rangers fan series, as well as co-hosting a Power Rangers podcast with over 300 episodes so far.

Casual fans are "far more open to the idea of dark/gritty because they see it as the show growing up with them," Kelley says. To hardcore fans, "it was either an abomination or the greatest unintended parody ever."

Kahn tells HitFix that the parody, of both Power Rangers and fan films in general, is definitely intended.

"The dark and gritty reboot thing is such a cliché that the intention was not only to make it dark and gritty but make it even darker and grittier than you could possibly imagine, hence the brains, the blood and the violence and the sex," Kahn said.

Kahn is set to answer questions about the film in a Reddit AMA on Friday at 2 p.m. We'll have to wait and see if there will be anywhere to watch it at the time.

For all the sad comic book and pop culture fans who weren't able to get tickets to San Diego Comic-Con, we've got good news for you: They run another convention, and it's closer to Los Angeles. Their little brother WonderCon Anaheim has been growing, with some comparing it to the Comic-Con of old — before it got way too crowded. It's this Friday through Sunday, April 3-5. They're starting to have big stars and lots of great panels, so if you want to get your geek heart sated, here are some of the events you won't want to miss.

Warner Bros. Presentation: San Andreas, Mad Max: Fury Road

San Andreas trailer

The most highly anticipated event at this weekend's convention, Warner Brothers is putting on a special presentation with footage from these two upcoming action films. They haven't announced which stars will be on hand, but these panels often surprise with star power, so you may get a visit from stars like "San Andreas's" Dwayne "The Rock" Johnson or "Mad Max: Fury Road's" Tom Hardy or Charlize Theron. At the Comic-Con panel last year for the "Mad Max" flick, the director talked in detail about the film, so you'll probably at least get his take on the franchise and its resurrection.

DC Comics TV shows: The Flash, Gotham, iZombie

The Flash trailer

While Marvel has been dominant on the big screen, DC has put out a diverse slate of TV shows, with "The Flash" being the biggest hit among them. It's among those getting a spotlight at WonderCon, with creators and stars dishing on the programs that have captured the imaginations of TV fans and comic fans alike. All three shows are also getting special video presentations, likely showing clips of what you can expect the rest of this season. And in case you didn't already know, "iZombie" comes from "Veronica Mars" creator Rob Thomas, so come find out about his latest project.

World Premiere: Batman vs. Robin

Batman vs. Robin trailer

It's become a tradition at both WonderCon and San Diego Comic-Con for DC Comics to debut their latest animated movie, and the new one is based on the critically acclaimed "Court of Owls" storyline by writer Scott Snyder. (Be sure to check out our previous interviews with Snyder — he's even an NPR fan.) The original story is based on how Batman thinks he knows everything there is to know about Gotham City and faces the discovery that there are deep secrets about the city that he had no idea about, and the film also emphasizes him fighting his son Damian.

Sing-alongs: Dr. Horrible & Batman's The Music Meister

Batman: The Brave and the Bold: Drives Us Bats

People go to comic conventions to geek out, and what's geekier than a good old-fashioned singalong? In addition to one for geek god Joss Whedon's much loved Web series "Dr. Horrible's Sing-Along Blog," they're also doing one for the musical episode of animated series "Batman: The Brave and the Bold" — which, just like "Dr. Horrible," features singing by the one and only Neil Patrick Harris. In the Batman cartoon, he plays the Music Meister, a Batman villain who makes both heroes and villains sing, as he drops some tunes of his own.

Superman: The Richard Donner Years Celebrity Super Reunion

Superman: The flying sequence

There's a reunion of stars from the first two of the classic Christopher Reeve Superman movies, including Lois Lane herself, Margot Kidder. You can also see the actors who played characters like Jimmy Olsen, several of the villains and more, as well as two of the producers. Find out what you don't know about the movie that broke ground when it came to depicting flight on-screen and, like the ads promised, made you believe a man could fly.

TV writing panels

Two panels will give you a peek into the world of the writers who write some of the hottest shows on TV: "TV Guide Magazine's Fan Favorites Showrunners" and "Inside The Writers' Room: Earth's Mightiest Writers Re-Assemble Redux." The first of those includes legendary TV showrunners like Dan Harmon of "Community" and the minds behind shows including "Orphan Black," "The Goldbergs" and more. Meanwhile, at the writers room panel, you'll get writers who've worked on shows like "Lost," "Firefly," "Heroes," "The Big Bang Theory," "Agent Carter" and more.

Fan culture programming track

This includes a lot of different panels, but it's a sign of the way fandom is shifting — it's a lifestyle that's far more diverse than it used to be, with a lot more gender parity. This track includes panels on topics like body confidence in cosplay, fashion, fitness, race and more. See what sparks your interest and might invite you into having an identity as a fan being a bigger part of your life while not letting anyone make you feel excluded.

There's so much more, like Will Forte doing a panel promoting his new show "The Last Man On Earth," the annual cosplay masquerade and so much more. Tickets are sold out for Saturday, but at press time, tickets were still available for both Friday and Sunday at WonderCon.

Features of azimuthal plots for RHEED and its new counterpart, RHEPD, are discussed. The plots, for both electrons and positrons, are determined using dynamical diffraction theory.

A method is adapted to generate a full rank realization of an abstract regular polyhedron with automorphism group H3.

Structure-mining finds and returns the best-fit structures from structural databases given a measured pair distribution function data set. Using databases and heuristics for automation it has the potential to save experimenters a large amount of time as they explore candidate structures from the literature.

The analytical solution of the problem of X-ray spherical-wave Laue diffraction in a single crystal with a linear change of thickness on the exit surface is derived. General equations are applied to a specific case of plane-wave Laue diffraction in a thick crystal under the conditions of the Borrmann effect.
