Over 60 percent of Illinois parents had never asked another parent about an unlocked firearm in their home before allowing their child to visit for a playdate, according to a survey from Ann & Robert H. Lurie Children's Hospital of Chicago published in Pediatrics. Many parents reported they had not asked about firearms because it never occurred to them to do so, which highlights a critical need to raise awareness of this important safety concern.

The direction of particle accelerator development is ever-increasing beam quality, currents and repetition rates. This poses a challenge to traditional diagnostics that directly intercept the beam due to the mutual destruction of both the beam and the diagnostic. An alternative approach is to infer beam parameters non-invasively from the synchrotron radiation emitted in bending magnets. However, inferring the beam distribution from a measured radiation pattern is a complex and computationally expensive task. To address this challenge we present SYRIPY (SYnchrotron Radiation In PYthon), a software package intended as a tool for performing inference of synchrotron-radiation-based diagnostics. SYRIPY has been developed using PyTorch, which makes it both differentiable and able to leverage the high performance of GPUs, two vital characteristics for performing statistical inference. The package consists of three modules: a particle tracker, Lienard–Wiechert solver and Fourier optics propagator, allowing start-to-end simulation of synchrotron radiation detection to be carried out. SYRIPY has been benchmarked against SRW, the prevalent numerical package in the field, showing good agreement and up to a 50× speed improvement. Finally, we have demonstrated how SYRIPY can be used to perform Bayesian inference of beam parameters using stochastic variational inference.

Physical optics simulations for beamlines and experiments allow users to test experiment feasibility and optimize beamline settings ahead of beam time in order to optimize valuable beam time at synchrotron light sources like NSLS-II. Further, such simulations also help to develop and test experimental data processing methods and software in advance. The Synchrotron Radiation Workshop (SRW) software package supports such complex simulations. We demonstrate how recent developments in SRW significantly improve the efficiency of physical optics simulations, such as end-to-end simulations of time-dependent X-ray photon correlation spectroscopy experiments with partially coherent undulator radiation (UR). The molecular dynamics simulation code LAMMPS was chosen to model the sample: a solution of silica nanoparticles in water at room temperature. Real-space distributions of nanoparticles produced by LAMMPS were imported into SRW and used to simulate scattering patterns of partially coherent hard X-ray UR from such a sample at the detector. The partially coherent UR illuminating the sample can be represented by a set of orthogonal coherent modes obtained by simulation of emission and propagation of this radiation through the coherent hard X-ray (CHX) scattering beamline followed by a coherent-mode decomposition. GPU acceleration is added for several key functions of SRW used in propagation from sample to detector, further improving the speed of the calculations. The accuracy of this simulation is benchmarked by comparison with experimental data.

Synchrotron-radiation-based techniques are a powerful tool for the investigation of materials. In particular, the availability of highly brilliant sources has opened the possibility to develop techniques sensitive to dynamics at the atomic scale such as X-ray photon correlation spectroscopy (XPCS). XPCS is particularly relevant in the study of glasses, which have been often investigated at the macroscopic scale by, for example, differential scanning calorimetry. Here, we show how to adapt a Flash calorimeter to combine XPCS and calorimetric scans. This setup paves the way to novel experiments requiring dynamical and thermodynamic information, ranging from the study of the crystallization kinetics to the study of the glass transition in systems that can be vitrified thanks to the high cooling rates reachable with an ultrafast calorimeter.

The differentially pumped rare-gas filter at the end of the VUV beamline of the Swiss Light Source has been adapted to house a windowless absorption cell for gases. Absorption spectra can be recorded from 7 eV to up to 21 eV photon energies routinely, as shown by a new water and nitrous oxide absorption spectrum. By and large, the spectra agree with previously published ones both in terms of resonance energies and absorption cross sections, but that of N2O exhibits a small shift in the { ilde{f D}} band and tentative fine structures that have not yet been fully described. This setup will facilitate the measurement of absorption spectra in the VUV above the absorption edge of LiF and MgF2 windows. It will also allow us to carry out condensed-phase measurements on thin liquid sheets and solid films. Further development options are discussed, including the recording of temperature-dependent absorption spectra, a stationary gas cell for calibration measurements, and the improvement of the photon energy resolution.

Bragg coherent X-ray diffraction imaging (BCDI) has emerged as a powerful technique for strain imaging and morphology reconstruction of nanometre-scale crystals. However, BCDI often suffers from angular distortions that appear during data acquisition, caused by radiation pressure, heating or imperfect scanning stages. This limits the applicability of BCDI, in particular for small crystals and high-flux X-ray beams. Here, we present a pre-processing algorithm that recovers the 3D datasets from the BCDI dataset measured under the impact of large angular distortions. We systematically investigate the performance of this method for different levels of distortion and find that the algorithm recovers the correct angles for distortions up to 16.4× (1640%) the angular step size dθ = 0.004°. We also show that the angles in a continuous scan can be recovered with high accuracy. As expected, the correction provides marked improvements in the subsequent phase retrieval.

The inherent ambiguity in reconstructed images from coherent diffraction imaging (CDI) poses an intrinsic challenge, as images derived from the same dataset under varying initial conditions often display inconsistencies. This study introduces a method that employs the Noise2Noise approach combined with neural networks to effectively mitigate these ambiguities. We applied this methodology to hundreds of ambiguous reconstructed images retrieved from a single diffraction pattern using a conventional retrieval algorithm. Our results demonstrate that ambiguous features in these reconstructions are effectively treated as inter-reconstruction noise and are significantly reduced. The post-Noise2Noise treated images closely approximate the average and singular value decomposition analysis of various reconstructions, providing consistent and reliable reconstructions.

An innovative dual-thickness semi-transparent beamstop designed to enhance the performance of small-angle X-ray scattering (SAXS) experiments is introduced. This design integrates two absorbers of differing thicknesses side by side into a single attenuator, known as a beamstop. Instead of completely stopping the direct beam, it attenuates it, allowing the SAXS detector to measure the transmitted beam through the sample. This approach achieves true synchronization in measuring both scattered and transmitted signals and effectively eliminates higher-order harmonic contributions when determining the transmission light intensity through the sample. This facilitates and optimizes signal detection and background subtraction. This contribution details the theoretical basis and practical implementation of this solution at the SAXS station on the 1W2A beamline at the Beijing Synchrotron Radiation Facility. It also anticipates its application at other SAXS stations, including that at the forthcoming High Energy Photon Source, providing an effective solution for high-precision SAXS experiments.

Bacterial ABC toxin complexes (Tcs) comprise three core proteins: TcA, TcB and TcC. The TcA protein forms a pentameric assembly that attaches to the surface of target cells and penetrates the cell membrane. The TcB and TcC proteins assemble as a heterodimeric TcB–TcC subcomplex that makes a hollow shell. This TcB–TcC subcomplex self-cleaves and encapsulates within the shell a cytotoxic `cargo' encoded by the C-terminal region of the TcC protein. Here, we describe the structure of a previously uncharacterized TcC protein from Yersinia entomophaga, encoded by a gene at a distant genomic location from the genes encoding the rest of the toxin complex, in complex with the TcB protein. When encapsulated within the TcB–TcC shell, the C-terminal toxin adopts an unfolded and disordered state, with limited areas of local order stabilized by the chaperone-like inner surface of the shell. We also determined the structure of the toxin cargo alone and show that when not encapsulated within the shell, it adopts an ADP-ribosyltransferase fold most similar to the catalytic domain of the SpvB toxin from Salmonella typhimurium. Our structural analysis points to a likely mechanism whereby the toxin acts directly on actin, modifying it in a way that prevents normal polymerization.

Appreciating that the role of the solute–solvent and other outer-sphere interactions is essential for understanding chemistry and chemical dynamics in solution, experimental approaches are needed to address the structural consequences of these interactions, complementing condensed-matter simulations and coarse-grained theories. High-energy X-ray scattering (HEXS) combined with pair distribution function analysis presents the opportunity to probe these structures directly and to develop quantitative, atomistic models of molecular systems in situ in the solution phase. However, at concentrations relevant to solution-phase chemistry, the total scattering signal is dominated by the bulk solvent, prompting researchers to adopt a differential approach to eliminate this unwanted background. Though similar approaches are well established in quantitative structural studies of macromolecules in solution by small- and wide-angle X-ray scattering (SAXS/WAXS), analogous studies in the HEXS regime—where sub-ångström spatial resolution is achieved—remain underdeveloped, in part due to the lack of a rigorous theoretical description of the experiment. To address this, herein we develop a framework for differential solution scattering experiments conducted at high energies, which includes concepts of the solvent-excluded volume introduced to describe SAXS/WAXS data, as well as concepts from the time-resolved X-ray scattering community. Our theory is supported by numerical simulations and experiment and paves the way for establishing quantitative methods to determine the atomic structures of small molecules in solution with resolution approaching that of crystallography.

Quantum crystallography is an emerging research field of science that has its origin in the early days of quantum physics and modern crystallography when it was almost immediately envisaged that X-ray radiation could be somehow exploited to determine the electron distribution of atoms and molecules. Today it can be seen as a composite research area at the intersection of crystallography, quantum chemistry, solid-state physics, applied mathematics and computer science, with the goal of investigating quantum problems, phenomena and features of the crystalline state. In this article, the state-of-the-art of quantum crystallography will be described by presenting developments and applications of novel techniques that have been introduced in the last 15 years. The focus will be on advances in the framework of multipole model strategies, wavefunction-/density matrix-based approaches and quantum chemical topological techniques. Finally, possible future improvements and expansions in the field will be discussed, also considering new emerging experimental and computational technologies.

The reaction of Co(NCS)2 with 4-methyl­pyridine N-oxide (C6H7NO) leads to the formation of two compounds, namely, tetra­kis­(4-methyl­pyridine N-oxide-κO)bis­(thio­cyanato-κN)cobalt(II), [Co(NCS)2(C6H7NO)4] (1), and tris­(4-methyl­pyridine N-oxide-κO)bis­(thio­cyanato-κN)cobalt(II), [Co(NCS)2(C6H7NO)3] (2). The asymmetric unit of 1 consists of one CoII cation located on a centre of inversion, as well as one thio­cyanate anion and two 4-methyl­pyridine N-oxide coligands in general positions. The CoII cations are octa­hedrally coordinated by two terminal N-bonding thio­cyanate anions in trans positions and four 4-methyl­pyridine N-oxide ligands. In the extended structure, these complexes are linked by C—H⋯O and C—H⋯S inter­actions. In compound 2, two crystallographically independent complexes are present, which occupy general positions. In each of these complexes, the CoII cations are coordinated in a trigonal–bipyramidal manner by two terminal N-bonding thio­cyanate anions in axial positions and by three 4-methyl­pyridine N-oxide ligands in equatorial positions. In the crystal, these complex mol­ecules are linked by C—H⋯S inter­actions. For compound 2, a nonmerohedral twin refinement was performed. Powder X-ray diffraction (PXRD) reveals that 2 was nearly obtained as a pure phase, which is not possible for compound 1. Differential thermoanalysis and thermogravimetry data (DTA–TG) show that compound 2 start to decompose at about 518 K.

Two different multi-component crystals consisting of papaverine [1-(3,4-di­meth­oxy­benz­yl)-6,7-di­meth­oxy­iso­quinoline, C20H21NO4] and fumaric acid [C4H4O4] were obtained. Single-crystal X-ray structure analysis revealed that one, C20H21NO4·1.5C4H4O4 (I), is a salt co-crystal composed of salt-forming and non-salt-forming mol­ecules, and the other, C20H21NO4·0.5C4H4O4 (II), is a salt–co-crystal inter­mediate (i.e., in an inter­mediate state between a salt and a co-crystal). In this study, one state (crystal structure at 100 K) within the salt–co-crystal continuum is defined as the ‘inter­mediate’.

A deep-learning algorithm is proposed for the inpainting of Bragg coherent diffraction imaging (BCDI) patterns affected by detector gaps. These regions of missing intensity can compromise the accuracy of reconstruction algorithms, inducing artefacts in the final result. It is thus desirable to restore the intensity in these regions in order to ensure more reliable reconstructions. The key aspect of the method lies in the choice of training the neural network with cropped sections of diffraction data and subsequently patching the predictions generated by the model along the gap, thus completing the full diffraction peak. This approach enables access to a greater amount of experimental data for training and offers the ability to average overlapping sections during patching. As a result, it produces robust and dependable predictions for experimental data arrays of any size. It is shown that the method is able to remove gap-induced artefacts on the reconstructed objects for both simulated and experimental data, which becomes essential in the case of high-resolution BCDI experiments.

Coherent diffractive imaging with X-ray free-electron lasers could enable structural studies of macromolecules at room temperature. This type of experiment could provide a means to study structural dynamics on the femtosecond timescale. However, the diffraction from a single protein is weak compared with the incoherent scattering from background sources, which negatively affects the reconstruction analysis. This work evaluates the effects of the presence of background on the analysis pipeline. Background measurements from the European X-ray Free-Electron Laser were combined with simulated diffraction patterns and treated by a standard reconstruction procedure, including orientation recovery with the expand, maximize and compress algorithm and 3D phase retrieval. Background scattering did have an adverse effect on the estimated resolution of the reconstructed density maps. Still, the reconstructions generally worked when the signal-to-background ratio was 0.6 or better, in the momentum transfer shell of the highest reconstructed resolution. The results also suggest that the signal-to-background requirement increases at higher resolution. This study gives an indication of what is possible at current setups at X-ray free-electron lasers with regards to expected background strength and establishes a target for experimental optimization of the background.

Family Builders, the adoption service of Catawba County Social Services, can now help adult adoptees, birth parents and their close relatives find each other. Not all counties in North Carolina offer this service, which is called Confidential Intermediary Services. Until recently all adoption records were sealed under North Carolina state law. In 2008, a new law took effect that allowed the release of certain records to adult adoptees and birth parents, if both parties agreed.

The annual Foothills Regional Conference for Parent Educators will be held Friday, June 3 from 9:00am until 2:00pm at the Catawba County Cooperative Extension Center in Newton. The 2011 theme is Helping Families Do More with Less.

In Jasmine Williams' family, graduating from the University of Michigan is a rite of passage. Her parents met on the campus, and her older sister graduated from the school a few years ago. She remembers sitting bundled up in the family section for that graduation. "It was overwhelming to feel so many people that proud," she says, "I remember sitting there watching her, and that was probably the first time I was like, 'OK, yeah, I like this. I can't wait to do this.'

This year, Williams' own graduation will look a bit different. The main undergraduate ceremony will be all virtual, though the university has invited students to watch that ceremony from the football stadium on campus known as the Big House. There will be no family members in attendance, and students will be required to have a negative COVID-19 test result to enter.

"I think it's hard not to downplay it when it's reduced to a Zoom," says Williams. But come Saturday, she's planning on donning her cap and gown and heading to the stadium with friends. "Knowing that we are going to the Big House to watch together as a class makes everything way more enjoyable for the weekend; to be able to at least get some remnants of what I witnessed years ago with my sister." Her family plans to host a streaming party from their home in Detroit.

As an academic year like no other comes to an end, colleges and universities are celebrating their graduates in a variety of ways. Some schools, like the University of Idaho and Virginia Tech are hosting multiple smaller, in-person ceremonies to comply with social distancing mandates. Others, like Iowa State, are hosting large ceremonies in football stadiums and outdoor arenas. There's also a handful that are doing virtual-only again, like the University of Washington and Portland State University. At some schools, including the University of Michigan and Emmanuel College in Boston, in-person events are restricted to just graduates; family and friends have to watch from a livestream.

For lots of students, the effort to be in-person is greatly appreciated. "You work hard those four years, you dream of that day, getting to graduate in-person and walk across the stage," says Jamontrae Christmon, a graduating senior at Tennessee State University in Nashville. For most of the year he assumed graduation would be virtual. He even sent out his graduation announcements to friends and family — and left the date off. Weeks later, he learned TSU would actually hold a May 1st in-person ceremony in the football stadium.

"I haven't been sleeping much this week at all. I'm just happy. Excited," says Christmon.

But planning for an event in an ongoing public health emergency has proven to be stressful. Steve Bennett, the chief of staff for academic affairs at Syracuse University, has worked to create commencement ceremonies that are as close to a normal year as possible.

"This may be the single most challenging special event that our team has put together, maybe ever," explains Bennett. "And it's because we keep having to plan towards a moving target."

Syracuse's plan for graduation is to have multiple smaller commencement ceremonies in their stadium; everyone in attendance has to be fully vaccinated or show proof of a recent negative COVID-19 test. According to state guidance, the stadium can only reach 10 % capacity, so graduates are limited to two guests per person. Despite the restrictions, the team that planned the ceremonies is determined to make it one that the class of 2021 deserves.

"The students have been through a lot this year. Graduating seniors lost a number of student experiences due to pandemic conditions that are important to them," says Bennett. That's why having the in-person component was essential. "It was really important to the university, given [the seniors'] commitment to us, that we have a commitment to them."

At California Lutheran University, in Thousand Oaks, Calif., graduation will be celebrated as a drive-in style event at the Ventura County Fairgrounds. Each graduate can bring one carful of people to the fairgrounds parking lot, which can accommodate up to 700 vehicles. Inspired by the city's drive-in concert events, there'll be a stage with speakers and a jumbo screen.

"That's ultimately what led us to our decision to have it at the fairgrounds. Since it's a drive-in and they're staying in their cars, they were allowed to bring family... that was just really important to us," says Karissa Oien, who works in academic affairs at California Lutheran University and is the lead organizer for the drive-in commencement. She's been planning the university's ceremonies for 13 years, and knows how important graduation can be — not just for students, but for those who helped them along the way as well.

"We wanted to have that moment again. Where the families can see their students cross the stage and be there with them."

Jamontrae Christmon, the graduating senior from Tennessee State University, will have his parents, an uncle and one of his sisters there with him at Hale Stadium. "It's just something about your parents being there," says Christmon, "you want to look into the audience and maybe see your parents and you hear them scream your name when they call your name to walk across the stage."

As the day gets closer, Christmon says he's been thinking about the moments of self-doubt he had along the way. "I could have easily said 'I'm not cut out for college' and just gave up, but I didn't." He says his family was a big part of that motivation.

"Not many in my family even attended college, let alone graduated. So this is a big deal," says Christmon. "To me it means I broke the cycle. And that's what they always wanted."

He expects his mother will cry, and likely, he will too.

New York City schools will reopen in full this fall with no options for virtual learning.

Mayor Bill de Blasio made the announcement during an appearance Monday on MSNBC, saying, "You can't have a full recovery without full-strength schools, everyone back sitting in those classrooms."

De Blasio said the nation's largest school district will meet in person five days a week, with no remote option available. New Jersey has similar plans, and other states want to limit remote lessons as well.

While the decision in New York is being celebrated as an important milestone on the path to returning to some level of normalcy from the pandemic, some parents remain fearful about sending their children back to in-person learning.

Meisha Porter, chancellor of the New York City Department of Education, has heard those concerns firsthand, but says "our schools have been the safest place in the city."

In an interview with NPR's Morning Edition, Porter said that with New York City in the process of a full reopening, "it's important that our schools be fully open, too."

Porter said the city would not make the vaccine a requirement for staff and teachers, but said more than 70,000 employees have already received at least one dose. The city will continue to monitor the health and safety of children, teachers and staff, she said, "but we know our schools have been safe and we need our children back."

Interview Highlights

What do you say to parents who are still really worried about the virus and may not want their kids to return, especially elementary aged kids who don't have access to a vaccine?

I say what we've said over and over again. You know, this past week, we've been at 0.3% — our seven-day positivity rate. Our schools are the safest place. And I've always said nothing, absolutely nothing, replaces the interaction and the learning that happens between a student and teacher in our classrooms. And so what I say to parents, as a parent, is we're going to continue to be in conversations. We're going to continue to make decisions around health and safety. We're going to continue to do those things that parents need us to do, that I need to ensure that we do, to make sure our buildings remain safe and we can get our babies back.

Is part of that effort a consideration about making the vaccine a requirement for staff and teachers?

At this moment, we're not making it a requirement, but we are encouraging [staff and teachers to get vaccinated], and we're going to really work with the city to provide access for students and families and teachers, as we've done over the last couple of months. And so right now, we're pushing and encouraging our staff to get vaccinated. ...

But I mean, wouldn't that help if you had 100%? I mean, children are required to show proof of of immunizations of vaccines to go to school. Why not maintain the same line for teachers and staff?

... I would say this, that we are not in a place where we want to, at this moment, mandate the vaccine. We want to continue to encourage. We all know that folks have had concerns about vaccines, and we want to continue to encourage that vaccines are safe and they are effective. I've been vaccinated along with the 70,000 DOE employees that have been vaccinated. And so we're not, at the moment where we are going to require it.

Have you heard from families who've come to rely on being able to have their kids, their teenagers, working while in school? There's evidence that those with that kind of economic need are those who want to continue with remote learning or some kind of hybrid.

I can tell you that I haven't heard that from families, that they want to they want remote learning so that their teenagers can continue to work. But I know, that that may be a reality for some families. And one of the things that we're doing this summer is increasing access to summer youth employment, increasing access to our learning-to-work programs for our young people, because we know how important it is for some young people to work. But it is equally, if not more important, that they maintain learning and have a connection to a strong and sound education, and we'll continue to do that through learning to work throughout the school year.

What about those students who have found that remote learning just works better for them? I mean, whether they are kids who have struggled socially in school environments, who have been bullied or kids with learning challenges who appreciate just being able to focus away from other students in the classroom. Are there any plans to come up with ways to better address their needs in the future?

So what we're looking forward to is leveraging what we've learned from remote learning as an innovation in our system as we move forward in return. And I think that's what's going to be important for us.

Do you know what that innovation is going to look like?

It's going to look like access to courses across schools and districts, breaking down district lines and walls, high-level courses, enrichment opportunities. You know, remote learning has expanded the universe of what schools should look like.
