The neutron powder diffractometer POWGEN at the Spallation Neutron Source has recently (2017–2018) undergone an upgrade which resulted in an increased detector complement along with a full overhaul of the structural design of the instrument. The current instrument has a solid angular coverage of 1.2 steradians and maintains the original third-generation concept, providing a single-histogram data set over a wide d-spacing range and high resolution to access large unit cells, detailed structural refinements and in situ/operando measurements.

Silicon nanowire-based sensors find many applications in micro- and nano-electromechanical systems, thanks to their unique characteristics of flexibility and strength that emerge at the nanoscale. This work is the first study of this class of micro- and nano-fabricated silicon-based structures adopting the scanning X-ray diffraction microscopy technique for mapping the in-plane crystalline strain (∊044) and tilt of a device which includes pillars with suspended nanowires on a substrate. It is shown how the micro- and nanostructures of this new type of nanowire system are influenced by critical steps of the fabrication process, such as electron-beam lithography and deep reactive ion etching. X-ray analysis performed on the 044 reflection shows a very low level of lattice strain (<0.00025 Δd/d) but a significant degree of lattice tilt (up to 0.214°). This work imparts new insights into the crystal structure of micro- and nanomaterial-based sensors, and their relationship with critical steps of the fabrication process.

An attempt has been made to combine small-angle scattering of X-rays or neutrons with scanning electron microscopy in reciprocal space, in order to establish a structural analysis method covering a wide range of sizes from micro- to macro-scales.

A new approach to variable-temperature measurements is presented, where the sample temperature changes continuously as a function of position.

This article presents the capability of the QMAX furnace, devoted to reciprocal space mapping through X-ray scattering at high temperature up to 2000 K.

A detailed theoretical and experimental comparison of dark-field electron holography (DFEH) and high-resolution X-ray diffraction (HRXRD) is performed. Both techniques are being applied to measure elastic strain in an array of transistors and the role of the geometric phase is emphasized.

The Smithsonian’s National Air and Space Museum has opened a new Public Observatory that contains a 16-inch, 3,000-pound Boller and Chivens telescope, on loan from the Smithsonian Astrophysical Observatory. Through this powerful telescope, museum visitors can now observe the sun (with a special filter), the moon and the brighter stars and planets, such as Venus, Jupiter and Saturn, during daylight hours. Funding for the project was provided by the National Science Foundation.

3D cell cultures enable the in vitro study of dynamic biological processes such as the cell cycle, but their use in high-throughput screens remains impractical with conventional fluorescent microscopy. Here, we present a screening workflow for the automated evaluation of mitotic phenotypes in 3D cell cultures by light-sheet microscopy. After sample preparation by a liquid handling robot, cell spheroids are imaged for 24 hours in toto with a dual-view inverted selective plane illumination microscope (diSPIM) with a much improved signal-to-noise ratio, higher imaging speed, isotropic resolution and reduced light exposure compared to a spinning disc confocal microscope. A dedicated high-content image processing pipeline implements convolutional neural network based phenotype classification. We illustrate the potential of our approach by siRNA knock-down and epigenetic modification of 28 mitotic target genes for assessing their phenotypic role in mitosis. By rendering light-sheet microscopy operational for high-throughput screening applications, this workflow enables target gene characterization or drug candidate evaluation in tissue-like 3D cell culture models.

The transformations from the primitive cells of the centered Bravais lattices to the corresponding centered cells have conventionally been listed as three-by-three matrices that transform three-space lattice vectors. Using those three-by-three matrices when working in the six-dimensional space of lattices represented as Selling scalars as used in Delone (Delaunay) reduction, one could transform to the three-space representation, apply the three-by-three matrices and then back-transform to the six-space representation, but it is much simpler to have the equivalent six-by-six matrices and apply them directly. The general form of the transformation from the three-space matrix to the corresponding matrix operating on Selling scalars (expressed in space S6) is derived, and the particular S6matrices for the centered Delone types are listed. (Note: in his later publications, Boris Delaunay used the Russian version of his surname, Delone.)

X-ray emission under electron-channelling conditions is used to distinguish between a non-centrosymmetric half-Heusler and a centrosymmetric full-Heusler crystal. For TiCo1.5+xSn the space-group determination based on a Rietveld refinement procedure became challenging for increasing Co content (x > 0.2), while electron channelling proved successful for higher Co content (x = 0.35). This technique can be used on crystals as small as (10 nm)3.

Robert Kinoshita, the Los Angeles native who designed the iconic robots from "Lost in Space" and "Forbidden Planet," has passed away. He was 100 years old.

Konishita died Dec. 9 at a Torrance nursing home, according to the Hollywood Reporter, citing family friend Mike Clark. His creations included "Forbidden Planet's" Robby the Robot, the B9 robot from "Lost in Space," Tobor from "Tobor the Great" and more. Kinoshita also created "Lost in Space's" iconic flying-saucer-shaped Jupiter 2 spaceship.

Kinoshita built the original miniature prototype of Robby the Robot out of wood and plastic by combining several different concepts, according to the Reporter; the Rafu Shimpo reported that he struggled with the design.

"I thought, what the hell. We’re wasting so much time designing and drawing one sketch after another. I said to myself, I’m going to make a model," Kinoshita told the Rafu Shimpo in a 2004 interview. "Then one day, the art director sees the model. He says, ‘Give me that thing.’ He grabbed it and ran. ... Ten minutes later, he comes running back and puts the model back on my desk and says, ‘Draw it!’"

Watch Kinoshita and his colleagues talking about the construction of Robby the Robot:

Robby the Robot's construction

The 1956 classic sci-fi movie "Forbidden Planet" — based on Shakespeare's "The Tempest" — went on to be nominated for a special effects Oscar.

Kinoshita later served as art director on the 1960s sci-fi TV series "Lost in Space," creating the arm-flailing robot — named B9 — who delivered the classic line "Danger! Danger, Will Robinson!" That robot received as much fan mail as the actual humans on the show, according to the Reporter.

Watch the robot's feud with "Lost in Space's" Dr. Smith:

The robot vs. Dr. Smith

The "Lost in Space" robot even inspired a B9 Robot Builders Club, featured in Forbes. Kinoshita sent a message in 2000 to the club, thanking them for their support for the robot he originally nicknamed "Blinky."

"I'm truly flabbergasted and honored by your support for 'Blinky!' It's a well-designed little beauty," Kinoshita wrote. "Your thoughtful remembrance is something we designers seldom are lucky enough to receive."

Kinoshita described the thought process behind its design in a 1998 interview.

"You're laying in bed, and something comes to you," he said. "Until, finally, you get to a point where you say, 'This could work,' 'OK, let's see what the boss man says.' And you present it to him."

He told the Rafu Shimpo that he tried to create his robots to disguise the fact that there was a person inside. "I tried to camouflage it enough so you’d wonder where the hell the human was," he said.

Both the Japanese-American Kinoshita and his wife, Lillian, were sent to an Arizona internment camp during World War II, though they were able to get out before the end of the war and moved to Wisconsin, according to the Reporter.

While in Wisconsin, Kinoshita learned industrial design and plastic fabrication, designing washing machines for the Army and Air Force before returning to California, according to the Rafu Shimpo.

Kinoshita said that he had to overcome racial prejudice to break into working in Hollywood.

Kinoshita attributed his long life to clean living — along with daily doses of apple cider vinegar, family friend Clark told the Reporter.

Kinoshita also worked as a designer and art director on numerous classic TV shows, including "Kojak," "Barnaby Jones," "Hawaii Five-O," "Bat Masterson," "Sea Hunt," "Tombstone Territory," "Star Trek" creator Gene Roddenberry's "Planet Earth" and more, according to his IMDB. His last TV show was 1984's "Cover Up."

Kinoshita grew up in Boyle Heights, according to the Reporter, attending Maryknoll Japanese Catholic School, Roosevelt High School and USC's School of Architecture. His career began with work on 1937's "100 Men and a Girl." Kinoshita graduated cum laude from USC, according to the Rafu Shimpo.

Watch Kinoshita speak at his 95th birthday gathering with the B9 Robot Builders Club. He said he hoped to make it to 100, and he ended up doing so.

Quaternion methods for obtaining solutions to the problem of finding global rotations that optimally align pairs of corresponding lists of 3D spatial and/or orientation data are critically studied. The existence of multiple literatures and historical contexts is pointed out, and the algebraic solutions of the quaternion approach to the classic 3D spatial problem are emphasized. The treatment is extended to novel quaternion-based solutions to the alignment problems for 4D translation and orientation data.

A new Mid-City store specializing in Spanish-language books for children may help chip away at a problem facing public schools expanding their dual-language programs and parents working to raise bilingual children: a lack of books beyond translations of "Curious George."

La Librería, the first children’s Spanish-language literature store in Los Angeles, opened Feb. 21 at a location on West Washington Boulevard. The brick-and-mortar is the dream of two moms who started out selling their volumes at book fairs.

When they first started out, co-founders Celene Navarrete and Chiara Arroyo couldn’t believe the lack locally of good, Spanish-language literature for children.

"Especially in Los Angeles, it was shocking to see the books that I read in Mexico, in my hometown, many of them were not available here," said Navarrete.

So Navarrete and Arroyo began traveling to Mexico, Guatemala, Colombia, and Spain to find authentic, Spanish-language children's books.

"We found the classics, we found the books that we read when we were little," she said.

Although 64 percent of Los Angeles' children are Latino, locating children's works in Spanish beyond translations of popular books in English isn't easy.

This matters to educators who say young children need to read and hear language-rich stories to expand their vocabulary and engage with characters in settings they recognize.

“I’ve been a bilingual educator since the '80s, and as an educator you’re always striving to look for authentic literature,” said Norma Silva, principal of the UCLA Lab School, a dual-language pre-kindergarten and elementary school attached to the university's Graduate School of Education.

By authentic literature, Silva means books originally written in Spanish, using the “luscious language” of rich descriptions and vivid characters. These writings often come from Spanish-speaking countries.

Books translated from English to Spanish aren't enough, Silva said. Besides rich language, Silva looks for books from different countries — "because it’s important that we’re able to delve deeply in understanding differences,” she said. Silva believes books need to reflect the diversity among the children and their families.

Since books from Mexico use different language and tell different tales than books from Guatemala, Colombia or Spain, Silva wants the children at her school to experience them all.

So that’s what adults want.  

According to Scholastic, one of the largest sellers in the U.S. of children's books in Spanish, kids have strong opinions about what they want to read. In a just completed survey, Scholastic found 91 percent of kids aged 6 to 17 said their favorite books were ones they picked themselves.

And kids age 6 to 8 are more likely to want characters that look like them than older kids.

The majority of the Spanish-language books in the March Scholastic catalog are translations of popular English language books, with a few books written in Spanish. The March catalog includes "Clifford the Dog" and stories about Sophia, the Disney princess, in Español.

"Kids who are Latino, they don’t just want to read books that are Latino or by Latino authors or with Latino characters — they want to be exposed to the diverse literature that is out there," said Mariel Lopez, who directs Scholastic's Spanish section.

Lopez adds that teachers in dual language immersion schools request Spanish language books which are translated from English so they can use the same book in both languages.

Luis Orozco, who has represented authors of books for Latino children for years, said changes in the publishing industry haven't helped writers of original Spanish-language works.

"As a result of the advent of technology, a lot of our [U.S.] publishers were forced to consolidate. So a book about a popular character that did well in English was easy to translate," he said.

But Orozco believes there is a major market among people who are eager for their kids to succeed and want more book choices for their children.

“They come to this country because they have better opportunities here," he said. "And the fact of the matter is that the traditional channels of distribution don’t have sales people that speak their language, that can speak to the authenticity of that product.”

At a recent presentation to parents, Orozco talked about the story, “Del Norte al Sur,” written by one of his authors, Rene Colato Lainez. It tackles the issue of family separation due to deportation.

After his talk, he said he sold out of every book.

Navarrete and Arroyo have scoured the Internet and traveled to Spanish-speaking countries to find authentic literature to sell. They found them, to their delight.

“There is this explosion of small independent [children’s] publishers in Spain, in Latin American countries,” Navarrete said. The two carefully selected books that would resonate with kids growing up in Los Angeles, and brought them back to stock their shelves.

At their store's grand opening on Feb. 21, parents and kids flooded in, devouring the books. One mother, bouncing her 10-month-old in a baby carrier, asked if the store had books from Guatemala.

To her surprise, the answer was "yes."

Arroyo and Navarrete hope eventually they can find a way for children to borrow their books for free, like a library. They said their goal is to break down barriers so that any child can read a book that speaks to them.

4 tips for finding and reading Spanish-language literature

1. Look for small or independent publishers that promote Latino authors and illustrators. Here are a few to start with:

• Lee & Low books
• Cinco Puntos Press
• Academia Cultural

2. Rich language matters. Browse for language in books that is rich and expressive. Children are never too young to be exposed to words heavy in imagery, that have double-meanings, or are alliterative. Through vivid descriptions, children can learn words to explain their own feelings and experiences.

3. Engage your children with the language as much as you engage them with the story. Explain the complex words and talk about context and meaning. Rich language can also help early readers with social emotional development, said Norma Silva of UCLA’s Lab School.

4. Besides books in hard copy, look for audio books. There is a long tradition of oral storytelling in many Latin American countries. Stories are told and passed on through generations, and today some Latino writers are also performers. Author Jose-Luis Orozco produces music, rhythms and basic literacy in addition to his stories.
