we introduce a novel approach for a real-time dual-frequency feedback system, which has been firstly used at the hard X-ray nanoprobe beamline of SSRF. The BiBEST can then efficiently stabilize X-ray beam position and stability in parallel, making use of different optical systems in the beamline.

Low-energy electron diffraction patterns contain precise information about the structure of the surface studied. However, retrieving the real space lattice periodicity from complex diffraction patterns is challenging, especially when the modeled patterns originate from superlattices with large unit cells composed of several symmetry-equivalent domains without a simple relation to the substrate. This work presents ProLEED Studio software, built to provide simple, intuitive and precise modeling of low-energy electron diffraction patterns. The interactive graphical user interface allows real-time modeling of experimental diffraction patterns, change of depicted diffraction spot intensities, visualization of different diffraction domains, and manipulation of any lattice points or diffraction spots. The visualization of unit cells, lattice vectors, grids and scale bars as well as the possibility of exporting ready-to-publish models in bitmap and vector formats significantly simplifies the modeling process and publishing of results.

This work introduces X-Ray Calc (XRC), an open-source software package designed to simulate X-ray reflectivity (XRR) and address the inverse problem of reconstructing film structures on the basis of measured XRR curves. XRC features a user-friendly graphical interface that facilitates interactive simulation and reconstruction. The software employs a recursive approach based on the Fresnel equations to calculate XRR and incorporates specialized tools for modeling periodic multilayer structures. This article presents the latest version of the X-Ray Calc software (XRC3), with notable improvements. These enhancements encompass an automatic fitting capability for XRR curves utilizing a modified flight particle swarm optimization algorithm. A novel cost function was also developed specifically for fitting XRR curves of periodic structures. Furthermore, the overall user experience has been enhanced by developing a new single-window interface.

This article presents a web-based framework to build a database without in-depth programming knowledge given a set of CIF dictionaries and a collection of CIFs. The framework consists of two main elements: the public site that displays the information contained in the CIFs in an ordered manner, and the restricted administrative site which defines how that information is stored, processed and, eventually, displayed. Thus, the web application allows users to easily explore, filter and access the data, download the original CIFs, and visualize the structures via JSmol. The modulated structures open database B-IncStrDB, the official International Union of Crystallography repository for this type of material and available through the Bilbao Crystallographic Server, has been re-implemented following the proposed framework.

Singer-songwriter Jason Isbell swept the major awards Wednesday night at the Americana Honors & Awards, creating another special moment with his wife, Amanda Shires.

Isbell won artist, album and song of the year during the 13th annual awards show Wednesday night at Ryman Auditorium in Nashville, Tennessee. Though surprisingly ignored by Grammy Awards voters, Isbell's album of the year winner "Southeastern" reverberated through the Americana community and made many of 2013's best-of lists.

He performed song of the year "Cover Me Up" with Shires, a significant figure on the album as muse and collaborator.

"I wrote this song for my wife," Isbell said. "I've had a lot of people ask me to dedicate it to their wives, girlfriends or cousin's wife or something strange like that. This was probably the hardest song I ever had to write because I wrote it for her and then I played it for her. It was very difficult. Do the things that scare you. That's the good stuff."

Isbell was one of this year's top nominees along with Rosanne Cash and Robert Ellis. Each had three nominations and all were up for artist, album and song of the year.

Many of the top nominees and honors recipients performed, including all five emerging artist nominees. Former couple Patty Griffin and Robert Plant made a surprise appearance and sang their collaboration "Ohio."

Sturgill Simpson, something of a modern cosmic cowboy, earned emerging artist of the year and the Milk Carton Kids took group/duo of the year. And Buddy Miller, now executive music producer for the television show "Nashville" and theAmericana's winningest performer, won his fifth instrumentalist of the year award.

The Americana Music Association also honored several pioneering musicians. Loretta Lynn received the lifetime achievement award for songwriting from Kacey Musgraves and Angaleena Presley.

"The truth is we both might cry giving out this award," Musgraves said.

Lynn, writer of some of country music's most important female empowerment songs, accepted the award in a sparkly lavender dress and her usual humble manner.

"When they told me I was going to get this award," she told the crowd, "I said, 'Naw, you got the wrong one.'"

Jackson Browne received the Spirit of Americana-Free Speech in Music award, Flaco Jimenez received the lifetime achievement award for instrumentalist and Taj Mahal earned the lifetime achievement award for performance.

"I was affected deeply by American music, near and far — my mother's interest in Southern music and my dad's interest in jazz and bebop and classical, all that kind of stuff," Mahal said in an interview. "But this music here, if you get this music, you can go anywhere in the world with it. For me, I play for the goddess of music. People ask me what I do and I go, deep Americana."

The Maya of Central America are thought to have been a kinder, gentler civilization, especially compared to the Aztecs of Mexico. At the peak of Mayan culture some 1,500 years ago, warfare seemed ritualistic, designed to extort ransom for captive royalty or to subjugate rival dynasties, with limited impact on the surrounding population. Only later, archeologists thought, did increasing drought and climate change lead to total warfare -- cities and dynasties were wiped off the map in so-called termination events -- and the collapse of the lowland Maya civilization around 1,000 A.D. (or C.E., current era). New evidence unearthed by National Science Foundation-funded researchers call all this into question, suggesting that the Maya engaged in scorched-earth military campaigns -- a strategy that aims to destroy anything of use, including cropland -- even at the height of their civilization, a time of prosperity and artistic sophistication. The finding also indicates that this increase in warfare, possibly associated with climate change and resource scarcity, was not the cause of the disintegration of the lowland Maya civilization.

SEASIDE, Calif. — Mike Gravel, a former U.S. senator from Alaska who read the Pentagon Papers into the Congressional Record and confronted Barack Obama about nuclear weapons during a later presidential run, has died. He was 91.

Gravel, who represented Alaska as a Democrat in the Senate from 1969 to 1981, died Saturday, according to his daughter, Lynne Mosier. Gravel had been living in Seaside, California, and was in failing health, said Theodore W. Johnson, a former aide.

Gravel's two terms came during tumultuous years for Alaska when construction of the trans-Alaska oil pipeline was authorized and when Congress was deciding how to settle Alaska Native land claims and whether to classify enormous amounts of federal land as parks, preserves and monuments.

He had the unenviable position of being an Alaska Democrat when some residents were burning President Jimmy Carter in effigy for his measures to place large sections of public lands in the state under protection from development.

Gravel feuded with Alaska's other senator, Republican Ted Stevens, on the land matter, preferring to fight Carter's actions and rejecting Stevens' advocacy for a compromise.

In the end, Congress passed the Alaska National Interest Lands Conservation Act of 1980, a compromise that set aside millions of acres for national parks, wildlife refuges and other protected areas. It was one of the last bills Carter signed before leaving office.

Gravel's Senate tenure also was notable for his anti-war activity. In 1971, he led a one-man filibuster to protest the Vietnam-era draft and he read into the Congressional Record 4,100 pages of the 7,000-page leaked document known as the Pentagon Papers, the Defense Department's history of the country's early involvement in Vietnam.

Gravel reentered national politics decades after his time in the Senate to twice run for president. Gravel, then 75, and his wife, Whitney, took public transportation in 2006 to announce he was running for president as a Democrat in the 2008 election ultimately won by Obama.

He launched his quest for the 2008 Democratic presidential nomination as a critic of the Iraq war.

"I believe America is doing harm every day our troops remain in Iraq — harm to ourselves and to the prospects for peace in the world," Gravel said in 2006. He hitched his campaign to an effort that would give all policy decisions to the people through a direct vote, including health care reform and declarations of war.

Gravel garnered attention for his fiery comments at Democratic forums.

In one 2007 debate, the issue of the possibility of using nuclear weapons against Iran came up, and Gravel confronted then-Sen. Obama. "Tell me, Barack, who do you want to nuke?" Gravel said. Obama replied: "I'm not planning to nuke anybody right now, Mike."

Gravel then ran as a Libertarian candidate after he was excluded from later Democratic debates.

In an email to supporters, he said the Democratic Party "no longer represents my vision for our great country." "It is a party that continues to sustain war, the military-industrial complex and imperialism — all of which I find anathema to my views," he said.

He failed to get the Libertarian nomination.

Gravel briefly ran for the Democratic nomination for president in 2020. He again criticized American wars and vowed to slash military spending. His last campaign was notable in that both his campaign manager and chief of staff were just 18 at the time of his short-lived candidacy.

"There was never any ... plan that he would do anything more than participate in the debates. He didn't plan to campaign, but he wanted to get his ideas before a larger audience," Johnson said.

Gravel failed to qualify for the debates. He endorsed Vermont Sen. Bernie Sanders in the contest eventually won by now-President Joe Biden.

Gravel was born Maurice Robert Gravel in Springfield, Massachusetts, on May 13, 1930.

In Alaska, he served as a state representative, including a stint as House speaker, in the mid-1960s.

He won his first Senate term after defeating incumbent Sen. Ernest Gruening, a former territorial governor, in the 1968 Democratic primary.

Gravel served two terms until he was defeated in the 1980 Democratic primary by Gruening's grandson, Clark Gruening, who lost the election to Republican Frank Murkowski.

Bill Cosby called on Howard University to support former co-star Phylicia Rashad's freedom of speech after she expressed support for him when his sexual assault conviction was overturned.

In a statement, Cosby also lashed out at the media, comparing journalists to the rioters who stormed the Capitol in January.

"Howard University you must support ones Freedom of Speech (Ms. Rashad), which is taught or suppose to be taught everyday at that renowned law school, which resides on your campus," Cosby said in a statement provided to NPR by his spokesman Andrew Wyatt.

"This mainstream media has become the Insurrectionists, who stormed the Capitol," Cosby continued in his statement. "Those same Media Insurrectionists are trying to demolish the Constitution of these United State of America on this Independence Day."

Cosby concluded by saying, "WE THE PEOPLE STAND IN SUPPORT OF MS. PHYLICIA RASHAD" in all caps.

Cosby's support of Rashad comes after the actress, who played his TV wife in The Cosby Show, defended the comedian in a tweet. Cosby was released from prison last week when the Pennsylvania Supreme Court vacated his sexual assault conviction on the grounds that his due process rights were violated.

"FINALLY!!!! A terrible wrong is being righted- a miscarriage of justice is corrected!" Rashad said last week.

The tweet has since been removed and Rashad later backpedaled, writing that she "fully support survivors of sexual assault coming forward." She also sent a letter of apology to Howard students

Many Howard alumni had expressed disappointment at the remarks. Howard University responded with its own tweet, stating that Dean Rashad's "initial tweet lacked sensitivity towards survivors of sexual assault."

Rashad was recently named Dean of Howard University's Chadwick Boseman College of Fine Arts.

Rashad, an acclaimed stage and screen artist, graduated from Howard magna cum laude in 1970 with a bachelor's in fine arts. She returned as a guest lecturer and adjunct faculty member.

In a statement announcing her appointment in May, Provost Anthony K. Wutoh said Rashad's "passion for the arts and student success makes her a perfect fit for this role."

One of the students Rashad mentored at Howard was the late actor Chadwick Boseman, for whom the school's College of Fine Arts is named.

Less than a week after trustees at the University of North Carolina at Chapel Hill belatedly voted to grant tenure to New York Times reporter Nikole Hannah-Jones, Howard University announced Hannah-Jones will instead be joining its faculty.

Howard, the prestigious historically Black university in Washington, D.C., also announced it is hiring writer and Howard alumnus Ta-Nehisi Coates, author of Between the World and Me.

Their positions were funded by nearly $20 million in donations from the Knight Foundation, the John D. and Catherine T. MacArthur Foundation and the Ford Foundation, as well as an anonymous donor.

The funding establishes the Knight Chair in Race and Journalism, a tenured position to be held by Hannah-Jones.

Hannah-Jones, who won a Pulitzer Prize for her 1619 Project, will also establish the Center for Journalism and Democracy, which the university says will train aspiring journalists in "the investigative skills and historical and analytical expertise needed to cover the crisis our democracy is facing."

The news is a blow to UNC, which has had its reputation damaged by its handling of Hannah-Jones' appointment to an endowed professorship at its journalism school. For months, trustees declined to consider granting her tenure, a highly unusual move considering her tenure was backed by the relevant academic leaders.

Some of the opposition came from Walter Hussman, an Arkansas newspaper publisher and alumnus whose $25 million donation to the UNC's journalism school led to its being named for him.

As NPR's David Folkenflik reported, Hussman said "he was given pause by some prominent scholars' criticism that Hannah-Jones distorted the historical record in arguing that the protection of slavery was one of the Founding Fathers' primary motivations in seeking independence from the British."

Amid the turmoil, other Black faculty members at UNC said they were considering leaving the university, and students protested on behalf of Hannah-Jones.

The university's student body president Lamar Richard penned an open letter last month to the UNC community, saying the university is unprepared for the reckoning that's required, and "[u]ntil this rebirth occurs, Carolina is not deserving of your talents, aspirations, or successes."

Hannah-Jones had said she would not accept UNC's offer without tenure, which UNC's Trustees finally approved in a 9-4 vote.

But the messy and contentious process spoiled it for her.

"Look what it took to get tenure," Hannah-Jones said, noting that every other chair of the position dating to the 1980s had been granted tenure, and that all were white. Hannah-Jones received unanimous approval from the faculty during the tenure process.

"And so to be denied it, and to only have that vote occur on the last possible day, at the last possible moment, after threat of legal action, after weeks of protest, after it became a national scandal – it's just not something that I want anymore," she told CBS This Morning.

Hannah-Jones said she never wanted her hiring to become a public scandal — she was simply hoping to give back to her beloved alma mater. And instead, she said, it became "embarrassing" to be passed over for tenure. She said she was never told by UNC-Chapel Hill's chancellor, provost or trustees why her tenure was not taken up in November or January.

The veteran journalist reportedly had offers from a number of universities after the botched process at UNC. So how did she pick Howard?

She said one of her few regrets was not going to Howard as an undergraduate. And she traced her choice to join its faculty to her own story, beginning as a second-grader bused to a white school.

"I've spent my entire life proving that I belong in elite white spaces that were not built for Black people," she told CBS. "I decided I didn't want to do that anymore. That Black professionals should feel free, and actually perhaps an obligation, to go to our own institutions and bring our talents and resources to our own institutions and help to build them up as well."

She said she won her battle for fair treatment at UNC, "but it's not my job to heal the University of North Carolina. That's the job of the people in power who created this situation in the first place."

Hannah-Jones said she's trying to raise even more money for Howard, and that she's eager to join the faculty this summer.

"To be able to bring that type of resources to a university that always punches above its weight, I'm so excited," she said. "Something great came out of this."

Bernie Sanders are leading the push to introduce a bill Tuesday that would make pandemic-related food benefits for college students permanent, and create grants for colleges to address hunger.; Credit: Chip Somodevilla/Getty Images

Democrats in the House and Senate are introducing legislation Tuesday that would make pandemic-related food benefits for college students permanent. The push is being led by Senators Elizabeth Warren, Democrat of Massachusetts and Bernie Sanders, a Vermont Independent,

In the December relief package, Congress increased the number of low-income college students eligible for Supplemental Nutrition Assistance Program (or SNAP) benefits for the duration of the pandemic. That included students who are eligible for work study, have an Expected Family Contribution of zero dollars, or qualify for a maximum Pell Grant on their federal financial aid form. According to The Century Foundation, this expansion affects about 3 million college students.

The legislation proposed Tuesday would make these changes permanent, including requiring the U.S. Education Department to notify students they may be eligible for SNAP when they fill out their student aid applications. The bill would also require the Department to collect data on hunger and food insecurity, and would create a $1 billion-a-year grant program for institutions to address hunger on campus.

"Far too many college students struggle to meet their basic needs while they get their education and the pandemic has made this problem even worse," Warren said in a statement to NPR. "As students take on a mountain of student loan debt, they shouldn't have to choose between paying tuition and eating."

The push comes amid new research that shows 39% of two-year college students are facing food insecurity; for students at 4-year schools the number affected is 29%, according to Temple University's Hope Center for College, Community and Justice.

Before the pandemic, in 2019, the U.S. Government Accountability Office issued a report on humger among college students, concluding that over a third of students don't always have enough to eat, and that federal systems already in place, including SNAP, could do a better job of helping them.

Many colleges have increased food benefits for their students, creating or expanding emergency grants, food pantries and other forms of assistance. State legislatures in several places including Virginia and Massachusetts have also moved to address issues of hunger on campus.

In a case originating with a California Highway Patrol officer's pursuit of a vehicle and ultimately entering the driver's home, the Supreme Court ruled Wednesday that police may not enter homes without a warrant for minor crimes.; Credit: Chris Carlson/AP

The U.S. Supreme Court ruled Wednesday that police cannot enter a home without a warrant when pursuing someone for a minor crime.

By a unanimous vote, the court declared that police violated the rights of a California man by pursuing him into his garage for allegedly playing loud music while driving down a deserted two-lane highway late at night.

Writing for the court majority, Justice Elena Kagan said police had no right to enter the man's home without a warrant for such a trivial offense.

"On many occasions, the officer will have good reason to enter – to prevent imminent harms of violence, destruction of evidence, or escape from the home," she wrote. "But when the officer has time to get a warrant, he must do so – even though the misdemeanant fled."

The court's ruling came in the case of Arthur Lange, who was playing loud music in his car late one night, at one point honking his horn several times. A California highway patrol officer, believing Lange was violating a noise ordinance, followed him, and when the motorist slowed to enter his driveway, the officer put on his flashing lights.

Lange, who later said he didn't notice the police car, drove into his garage. The officer, in "hot pursuit," got out of his car and put his foot under the closing garage door sensor to force the door open again. He had no warrant to enter the home, but once inside, he said, he smelled liquor on Lange's breath and arrested him, not only for the noise violation, but also for driving under the influence.

Lange appealed all the way to the Supreme Court, contending that the officer had no right to enter his home without a warrant and that the DUI evidence had been illegally obtained.

The Supreme Court has long held that police may conduct a warrantless search when pursuing a fleeing felon. The question in Lange's case was whether police are free to do the same thing when pursuing someone suspected of a minor offense like playing loud music.

"[P]ursuit of a misdemeanant does not trigger a categorical rule allowing a warrantless home entry," she wrote.

Although more than $500 million in federally funded research on Persian Gulf War veterans between 1994 and 2014 has produced many findings, there has been little substantial progress in the overall understanding of the health effects, particularly Gulf War illness, resulting from military service in the war, says a new report from the Institute of Medicine (IOM) of the National Academies of Sciences, Engineering, and Medicine.
