The ability to freely control the polarization of X-rays enables measurement techniques relying on circular or linear dichroism, which have become indispensable tools for characterizing the properties of chiral molecules or magnetic structures. Therefore, the demand for polarization control in X-ray free-electron lasers is increasing to enable polarization-sensitive dynamical studies on ultrafast time scales. The soft X-ray branch Athos of SwissFEL was designed with the aim of providing freely adjustable and arbitrary polarization by building its undulator solely from modules of the novel Apple X type. In this paper, the magnetic model of the linear inclined and circular Apple X polarization schemes are studied. The polarization is characterized by measuring the angular electron emission distributions of helium for various polarizations using cold target recoil ion momentum spectroscopy. The generation of fully linear polarized light of arbitrary angle, as well as elliptical polarizations of varying degree, are demonstrated.

Neutron diffraction beamlines have traditionally relied on deploying large detector arrays of 3He tubes or neutron-sensitive scintillators coupled with photomultipliers to efficiently probe crystallographic and microstructure information of a given material. Given the large upfront cost of custom-made data acquisition systems and the recent scarcity of 3He, new diffraction beamlines or upgrades to existing ones demand innovative approaches. This paper introduces a novel Timepix3-based event-mode imaging neutron diffraction detector system as well as first results of a silicon powder diffraction measurement made at the HIPPO neutron powder diffractometer at the Los Alamos Neutron Science Center. Notably, these initial measurements were conducted simultaneously with the 3He array on HIPPO, enabling direct comparison. Data reduction for this type of data was implemented in the MAUD code, enabling Rietveld analysis. Results from the Timepix3-based setup and HIPPO were benchmarked against McStas simulations, showing good agreement for peak resolution. With further development, systems such as the one presented here may substantially reduce the cost of detector systems for new neutron instrumentation as well as for upgrades of existing beamlines.

"This is a petty, partisan power grab that is absolutely retaliation towards my office," Arizona Democratic Secretary of State Katie Hobbs says of the new law.; Credit: Ross D. Franklin/AP

Arizona Republicans have stripped the secretary of state's office — currently held by a Democrat — of the right to defend the state's election laws in court, or choose not to, a change enacted as part of Arizona's newly signed budget.

The spending blueprint that Gov. Doug Ducey signed into law Wednesday declares that the attorney general — currently a position occupied by Republican Mark Brnovich — has sole authority over election-related litigation.

If the secretary of state and attorney general were to disagree over a legal strategy when Arizona election laws are challenged, the new law states that "the authority of the attorney general to defend the law is paramount."

Republicans also adopted language stating it's their intent for the law to apply through Jan. 2, 2023, coinciding with the end of Democrat Katie Hobbs' term as secretary of state.

Hobbs, the top election official in Arizona who's now running for governor, says her lawyers are looking at whether this change violates the Arizona Constitution.

"This is a petty, partisan power grab that is absolutely retaliation towards my office," Hobbs said. "It's clear by the fact that it ends when my term ends. ... It is at best legally questionable, but at worst, likely unconstitutional."

Republicans have generally cast the law as a cost-saving measure, citing Hobbs and Brnovich's frequent disagreements over how to defend state election laws that have been challenged in court. In 2020, Hobbs filed complaints with the state bar against Brnovich and other lawyers in his office.

Other election provisions in the budget

The budget includes a number of other election provisions, and it comes weeks after Republicans enacted new restrictions on early voting in the state, and as a controversial review of 2020 election results in Maricopa County continues.

Here are some of the other election-related measures in the budget:

• New laws could soon require watermarks, QR codes and other security measures to be printed on ballots.
• There's a new mandate to inspect state and county voter registration databases and create a report on voters who cast federal-only ballots — an option available to Arizonans who don't show proof of citizenship to register to vote in the state, but are still allowed to register under federal law.
• And a new task force would investigate alleged social media bias as an unreported in-kind political contribution.

The ballot security measures, though not mandated by law in the budget, have the potential to be the most cumbersome and costly requirement for county election officials to implement.

The budget amendment provides a list of 10 "ballot fraud countermeasures" for counties to choose from — features like holographic foil, background designs similar to those found on banknotes and ultraviolet or infrared ink. If mandated, counties would have to implement any combination of at least three features from the list on their ballots. The budget provides $12 million to pay for those features, to be split among Arizona's 15 counties.

"By everyone's admission, there is only one company that can do any of this," said Jennifer Marson, executive director of the Arizona Association of Counties. "And so now, we can't have a competitive bid process or a traditional procurement process at the county or state level to use these countermeasures because we're locked into one company."

That company is Authentix, a Texas-based firm that provided Republican Rep. Mark Finchem with a sample ballot that included watermarks, QR codes and other security measures. Finchem had the sample ballot on display at the Capitol in March. According to the Yellow Sheet Report, it could be five times more expensive to print ballots with those security measures as it is to print paper ballots currently in use.

Marson said Finchem has acknowledged the security levels required of companies in the budget amendment could only be met by Authentix, and has vowed to mandate the ballot security measures in the "very near future."

Finchem defended the company in a brief email. He wrote that Authentix "offers these countermeasures to governments around the world for document and tax stamp security."

As the budget was being considered, Democrats like Sen. Tony Navarrete said the amendment is part of a broad effort to solidify conspiracy theories of election fraud.

"It's important for us to make sure we vote down conspiracy-laced amendments that are going to hurt the integrity of our election system in the state of Arizona and encourage other states to have these bad copycat laws spread like wildfire," he said.

Preparations continue in Surfside, Fla. for the demolition of a portion of the Champlain Towers South still standing after much of the building collapsed in the early morning hours on June 24.

Miami-Dade County Mayor Daniella Levine Cava told reporters on Sunday that bringing down the remainder of the collapsed condominium in a controlled fashion is crucial to the safety of search and rescue teams.

Those teams have paused their work so demolition can take place. Levine Cava said officials are still unsure of a specific time that the demolition will occur.

"Our top priority is that the building can come down as soon as possible — no matter what time that occurs — and safely as possible," Levine Cava said at a morning news conference.

The number of confirmed dead from the collapse remains at 24. The number of people unaccounted for remains at 121.

Preparations for the demolition come as Tropical Storm Elsa is tracking towards southern Florida. The storm is expected to hit the area Monday and Tuesday.

The instability of the building could be made worse by the storm, which is expected to bring strong winds and rain at the beginning of the week. Mayor Levine Cava said that as soon as the demolition has occurred, search and rescue efforts are expected to resume.

Ahead of Elsa's arrival in Florida, Gov. Ron DeSantis issued a state of emergency Saturday for 15 counties, including Miami-Dade.

On Sunday, he expressed optimism that the Surfside area may be spared from the worst of the storm.

"We could see some gusts, but it has tracked west over the last day and a half — more so than the initial forecast," he said. "So, we'll just keep watching that."

SURFSIDE, Fla. — Crews used explosives late Sunday night to demolish the remaining structure at Champlain Towers South in Surfside, Fla.

The heavily damaged condo building was knocked down at about 10:30 p.m. Eastern time.

The targeted blast caused the tower to fold and crumble, sending a large plume of dust and debris over a section of the beachside community. A crowd watching from a distance prayed as the building came down.

Before the structure was leveled, Miami-Dade County police urged residents who live nearby to remain indoors and shelter in place.

Miami-Dade County officials said removing the tower was an essential step so search and rescue teams could resume scouring the rubble pile for victims of the disaster.

Officials suspended recovery efforts on Saturday because of concerns about the danger posed by the unstable building.

"It will be safe to resume the search activities very shortly after the blast and that's when we'll resume it," said Miami-Dade County Mayor Daniella Levine Cava at a press conference Sunday evening.

Demolition of the tower was also accelerated because of Tropical Storm Elsa, which could hit South Florida with high winds and heavy rains as early as Monday.

Search efforts had been ongoing since the morning of June 24, when much of the 12-story condo complex suffered a "progressive collapse" and dozens of apartments were reduced to rubble in a matter of seconds.

The number of confirmed dead from the disaster remains at 24, with the number of people unaccounted for at 121.

Rep. Debbie Wasserman Schultz, D-Fla., told reporters Sunday the demolition of the remaining tower added to the sorrow for families who lived in the complex, destroying homes and possessions.

"So often demolitions of buildings are a spectacle, it's almost like a show," Schultz said. "This demolition is a tragic situation."

Local officials assured former residents and the public that everything possible had been done to rescue pets left behind in the structure.

"Folks can be comfortable we're not leaving anyone behind, including our beloved pets," Surfside Mayor Charles Burkett told reporters.

Multiple investigations are already underway into the cause of the collapse.

Documents acquired by NPR from an anonymous source show the condo association's board received warnings from an engineering firm beginning in 2018 that the structure needed extensive repairs.

A memo sent by the association to Champlain Towers South residents ahead of a May 2021 board meeting acknowledged the "desperate needs of the building."

Miami-Dade County mayor Daniella Levine Cava said on Monday morning that three more victims have been recovered from the ruins of the collapsed condo tower in Surfside, Fl., bringing the total death toll so far to 27.

Cava added that the demolition of the rest of Champlain Towers South "was executed exactly as planned" the previous evening, and that it would now allow rescue teams to work on a section of the collapsed building that was previously inaccessible. She noted that 118 individuals remain unaccounted for.

"Truly, we could not continue without bringing this building down," Cava said. "The area closest to the building was not accessible, due to the enormous risk to the team of first responders, because of the instability of the building."

According to Florida Governor Ron DeSantis, the newly accessible section of rubble is also from a part of the building where many bedrooms were located, and may contain the remains of many victims. The building collapsed in the middle of the night.

Authorities had been concerned that an approaching tropical storm might topple the standing part of the building onto the section that had already collapsed. That would have been a massive setback in the search for victims and for clues to the cause of the disaster.

Tropical Storm Elsa now appears to be tracking further to the west, and is more likely to hit the west coast of Florida, rather than the site of the disaster. But officials at the National Weather Service say the storm's course still could change.

Cava acknowledged that demolishing people's homes "is a devastating decision" and said that "our teams are doing everything possible to help those who lost their home begin to rebuild."

She said that authorities are working with insurance companies and the Federal Emergency Management Agency to streamline claims and help those who've lost homes and property.

One animal rescue volunteer had gone to court to stop the demolition of the rest of the tower, asking the court to allow more time to rescue pets that might still be trapped inside. The judge denied the motion.

Cava said in her Monday briefing that Miami-Dade rescue teams had already gone through parts of the building that were still accessible, "searching in closets and under beds" to find missing pets.

PITTSBURGH (September 2, 2016) ... The potential to develop "materials that compute" has taken another leap at the University of Pittsburgh's Swanson School of Engineering, where researchers for the first time have demonstrated that the material can be designed to recognize simple patterns. This responsive, hybrid material, powered by its own chemical reactions, could one day be integrated into clothing and used to monitor the human body, or developed as a skin for "squishy" robots.
