ABSTRACT Introduction Individuals with schizophrenia present anomalies in the extension and plasticity of the peripersonal space (PPS), the section of space surrounding the body, shaped through motor experiences. A weak multisensory integration in PPS would contribute to an impairment of self-embodiment processing, a core feature of the disorder linked to specific subjective experiences. In this […]

On October 5, SpaceX Crew Dargon blasted off to the International Space Station. Anna Kikina, a woman cosmonaut from Russia, was on board the SpaceX spacecraft. "A SpaceX Falcon 9 rocket propelled the Dragon Endurance spacecraft into orbit carrying NASA astronauts Nicole Mann as mission commander, and Josh Cassada, pilot. JAXA (Japan Aerospace Exploration Agency) astronaut Koichi Wakata and Roscosmos cosmonaut Anna Kikina, also aboard the Dragon, will serve as mission specialists for their science expedition in microgravity aboard the space station," NASA wrote. The participation of a Russian cosmonaut in the launch launch was made possible owing to the cross-flight programme: a Russian cosmonaut boarded SpaceX, and an American astronaut flew to the ISS on board a Soyuz spacecraft.

The future of the International Space Station remains extremely vague. News reports about technical problems on board the ISS became, one might say, traditional. Is it time to decide? The service life of the International Space Station extends till 2024. At the same time, now is the time to decide what should be done to the station afterwards. Late last year, Deputy Prime Minister Yuri Borisov said that the future of the ISS would be determined in the first quarter of 2021."The fate of the ISS has not been fully decided yet, it will be determined, probably, in the first quarter of next year," Borisov told TASS. He also added that Roscosmos corporation plans to launch a new segment of the ISS, which is expected to become the basis for the Russian orbital station in the future.It goes about "Nauka" ("Science") module, which will become a space laboratory for Russian cosmonauts. Does Russia want the ISS to last longer? Ivan Moiseev, the scientific director of the Institute of Space Policy, believes that stopping international cooperation was out of the question. "There is an official permit to run the station till 2024 - till 2025, in fact. All the countries participating in the ISS agreement agreed to consider the issue of extending the service life of the station till 2028-2030 - that was six months ago," the expert told Pravda.Ru.However, the situation took a turn due to a series of accidents on board the ISS."Those were insignificant accidents, but they create a relevant information background. The government had to decide. If it was not for those accidents, they would have quietly extended the service life of the ISS until 2028, and it would be beneficial to everyone. But when those accidents started happening, they led the general public to believe that the station was falling apart. There were official statements made about the need to finish its work," Ivan Moiseev said.However, the expert believes that the work of the station should be extended. "Therefore, the government apparently will make a decision on the matter in early 2021," he believes.

In 2025, the era of the International Space Station is supposed to end. Russia, China and the United States will switch to their own programs in near space. All space powers have their problems. Who is going to win the race? Russia to flood its section of the ISS in 2024 Roscosmos CEO Dmitry Rogozin wrote in Telegram that the Russian Space Agency started working on the construction of the first module of the new Russian orbital station. "The work on the first base module for the new Russian orbital service station is underway. The Energia Rocket and Space Corporation has been tasked to ensure its readiness for launch into orbit in 2025," Rogozin wrote.

Russia is making pointless and even strange steps in and around space, and they are all the more sad because they cost the Russian budget a lot of money and deprive the nation of the space power status. Why the United States would like to work with Russia in space, but Russia would not The space race has been getting increasingly intense lately. Different countries declare their claims to the Moon. It appears that China is going to be the first to go there. The exploration or even the colonisation of Mars is next on the list. Space exploration by private corporations is in full swing:

On Thursday, March 21, the Soyuz-2.1a rocket with the Soyuz MS-25 manned spacecraft was supposed to blast off from launch pad No. 31 (Vostok) at Baikonur Cosmodrome. The rocket launch was aborted at the last moment. The countdown was stopped approximately 20 seconds before the start time. "Attention at the launch complex. The launch was automatically aborted. Bring the units of the launch complex to their original condition. Prepare to be parked for 24 hours,” the announcer of the broadcast hosted by Roscosmos said. The launch was dedicated to the 90th anniversary of Soviet cosmonaut and first man in space Yuri Gagarin.

The Orion upper stage of the Angara-A5 heavy rocket launched the Gagarinets small satellite into low Earth orbit, Roscosmos said on its Telegram channel. "The Cubesat 3U format satellite was created by Russian private company Avant Space and is intended to test elements of the service platform,” the state corporation said. After the launch of the Gagarinets, the upper stage continued its work.

Chinese manned spacecraft Shenzhou-19 with three taikonauts on board was successfully launched into low-Earth orbit from the Jiuquan Satellite Launch Center in northwestern China, UDN Global reports. The spacecraft blasted off on October 29 at 23:27 Moscow time, or October 30 at 04:27 local time. A Long March 2 °F-19 launch vehicle was used for the liftoff. About ten minutes into the flight, the Shenzhou-19 manned spacecraft successfully separated from the rocket and flew into orbit. There are three crew members on board the Shenzhou-19. They will conduct 86 scientific experiments in space, including experiments in the field of medicine, biology, fundamental physics of microgravity, materials science and space technology, the agency notes.

Following the work of Day & Hawthorne [Acta Cryst. (2022), A78, 212–233] and Day et al. [Acta Cryst. (2024), A80, 258–281], the program GraphT–T has been developed to embed graphical representations of observed and hypothetical chains of (SiO4)4− tetrahedra into 2D and 3D Euclidean space. During embedding, the distance between linked vertices (T–T distances) and the distance between unlinked vertices (T⋯T separations) in the resultant unit-distance graph are restrained to the average observed distance between linked Si tetrahedra (3.06±0.15 Å) and the minimum separation between unlinked vertices is restrained to be equal to or greater than the minimum distance between unlinked Si tetrahedra (3.713 Å) in silicate minerals. The notional interactions between vertices are described by a 3D spring-force algorithm in which the attractive forces between linked vertices behave according to Hooke's law and the repulsive forces between unlinked vertices behave according to Coulomb's law. Embedding parameters (i.e. spring coefficient, k, and Coulomb's constant, K) are iteratively refined during embedding to determine if it is possible to embed a given graph to produce a unit-distance graph with T–T distances and T⋯T separations that are compatible with the observed T–T distances and T⋯T separations in crystal structures. The resultant unit-distance graphs are denoted as compatible and may form crystal structures if and only if all distances between linked vertices (T–T distances) agree with the average observed distance between linked Si tetrahedra (3.06±0.15 Å) and the minimum separation between unlinked vertices is equal to or greater than the minimum distance between unlinked Si tetrahedra (3.713 Å) in silicate minerals. If the unit-distance graph does not satisfy these conditions, it is considered incompatible and the corresponding chain of tetrahedra is unlikely to form crystal structures. Using GraphT–T, Day et al. [Acta Cryst. (2024), A80, 258–281] have shown that several topological properties of chain graphs influence the flexibility (and rigidity) of the corresponding chains of Si tetrahedra and may explain why particular compatible chain arrangements (and the minerals in which they occur) are more common than others and/or why incompatible chain arrangements do not occur in crystals despite being topologically possible.

The reciprocal of a non-primitive unit cell is not a unit cell and the basis vectors do not correspond to cell lengths.

Animations, videos and 3D models have been designed to visualize the effects of symmetry operators on selected cases of crystal structures, pointing out the relationship with the diagrams published in International Tables for Crystallography, Vol. A.

A series of animations, videos and 3D models that were developed, filmed or built to teach the symmetry properties of crystals are described. At first, these resources were designed for graduate students taking a basic crystallography course, coming from different careers, at the National Autonomous University of Mexico. However, the COVID-19 pandemic had the effect of accelerating the generation of didactic material. Besides our experience with postgraduate students, we have noted that 3D models attract the attention of children, and therefore we believe that these models are particularly useful for teaching children about the assembled arrangements of crystal structures.

The dualism between direct and reciprocal space is at the origin of well known relations between basis vectors in the two spaces. It is shown that when a coordinate system corresponding to a non-primitive unit cell is adopted, this dualism has to be handled with care. In particular, the reciprocal of a non-primitive unit cell is not a unit cell but a region in reciprocal space that does not represent a unit of repetition by translation. The basis vectors do not correspond to reciprocal-space cell lengths, contrary to what is stated even in the core CIF dictionary. The corresponding unit cell is a multiple of this region. The broken correspondence between basis vectors and unit cell is at the origin of the integral reflection conditions.

The Photoelectron-Related Image and Nano-Spectroscopy (PRINS) endstation located at the Taiwan Photon Source beamline 27A2 houses a photoelectron momentum microscope capable of performing direct-space imaging, momentum-space imaging and photoemission spectroscopy with position sensitivity. Here, the performance of this microscope is demonstrated using two in-house photon sources – an Hg lamp and He(I) radiation – on a standard checkerboard-patterned specimen and an Au(111) single crystal, respectively. By analyzing the intensity profile of the edge of the Au patterns, the Rashba-splitting of the Au(111) Shockley surface state at 300 K, and the photoelectron intensity across the Fermi edge at 80 K, the spatial, momentum and energy resolution were estimated to be 50 nm, 0.0172 Å−1 and 26 meV, respectively. Additionally, it is shown that the band structures acquired in either constant energy contour mode or momentum-resolved photoemission spectroscopy mode were in close agreement.

X-ray diffraction imaging (XDI) is utilized for visualizing the structures of non-crystalline particles in material sciences and biology. In the structural analysis, phase-retrieval (PR) algorithms are applied to the diffraction amplitude data alone to reconstruct the electron density map of a specimen particle projected along the direction of the incident X-rays. However, PR calculations may not lead to good convergence because of a lack of diffraction patterns in small-angle regions and Poisson noise in X-ray detection. Therefore, the PR calculation is still a bottleneck for the efficient application of XDI in the structural analyses of non-crystalline particles. For screening maps from hundreds of trial PR calculations, we have been using a score and measuring the similarity between a pair of retrieved maps. Empirically, probable maps approximating the particle structures gave a score smaller than a threshold value, but the reasons for the effectiveness of the score are still unclear. In this study, the score is characterized in terms of the phase differences between the structure factors of the retrieved maps, the usefulness of the score in screening the maps retrieved from experimental diffraction patterns is demonstrated, and the effective resolution of similarity-score-selected maps is discussed.

Small-angle-scattering tensor tomography is a technique for studying anisotropic nanostructures of millimetre-sized samples in a volume-resolved manner. It requires the acquisition of data through repeated tomographic rotations about an axis which is subjected to a series of tilts. The tilt that can be achieved with a typical setup is geometrically constrained, which leads to limits in the set of directions from which the different parts of the reciprocal space map can be probed. Here, we characterize the impact of this limitation on reconstructions in terms of the missing wedge problem of tomography, by treating the problem of tensor tomography as the reconstruction of a three-dimensional field of functions on the unit sphere, represented by a grid of Gaussian radial basis functions. We then devise an acquisition scheme to obtain complete data by remounting the sample, which we apply to a sample of human trabecular bone. Performing tensor tomographic reconstructions of limited data sets as well as the complete data set, we further investigate and validate the missing wedge problem by investigating reconstruction errors due to data incompleteness across both real and reciprocal space. Finally, we carry out an analysis of orientations and derived scalar quantities, to quantify the impact of this missing wedge problem on a typical tensor tomographic analysis. We conclude that the effects of data incompleteness are consistent with the predicted impact of the missing wedge problem, and that the impact on tensor tomographic analysis is appreciable but limited, especially if precautions are taken. In particular, there is only limited impact on the means and relative anisotropies of the reconstructed reciprocal space maps.

X-ray and neutron crystallography, as well as cryogenic electron microscopy (cryo-EM), are the most common methods to obtain atomic structures of biological macromolecules. A feature they all have in common is that, at typical resolutions, the experimental data need to be supplemented by empirical restraints, ensuring that the final structure is chemically reasonable. The restraints are accurate for amino acids and nucleic acids, but often less accurate for substrates, inhibitors, small-molecule ligands and metal sites, for which experimental data are scarce or empirical potentials are harder to formulate. This can be solved using quantum mechanical calculations for a small but interesting part of the structure. Such an approach, called quantum refinement, has been shown to improve structures locally, allow the determination of the protonation and oxidation states of ligands and metals, and discriminate between different interpretations of the structure. Here, we present a new implementation of quantum refinement interfacing the widely used structure-refinement software Phenix and the freely available quantum mechanical software ORCA. Through application to manganese superoxide dismutase and V- and Fe-nitro­genase, we show that the approach works effectively for X-ray and neutron crystal structures, that old results can be reproduced and structural discrimination can be performed. We discuss how the weight factor between the experimental data and the empirical restraints should be selected and how quantum mechanical quality measures such as strain energies should be calculated. We also present an application of quantum refinement to cryo-EM data for particulate methane monooxygenase and show that this may be the method of choice for metal sites in such structures because no accurate empirical restraints are currently available for metals.

In recent decades, sustained theoretical and software developments have clearly established that representation analysis and magnetic symmetry groups are complementary concepts that should be used together in the investigation and description of magnetic structures. Historically, they were considered alternative approaches, but currently, magnetic space groups and magnetic superspace groups can be routinely used together with representation analysis, aided by state-of-the-art software tools. After exploring the historical antagonism between these two approaches, we emphasize the significant advancements made in understanding and formally describing magnetic structures by embracing their combined use.

Predicting crystal symmetry simply from chemical composition has remained challenging. Several machine-learning approaches can be employed, but the predictive value of popular crystallographic databases is relatively modest due to the paucity of data and uneven distribution across the 230 space groups. In this work, virtually all crystallographic information available to science has been compiled and used to train and test multiple machine-learning models. Composition-driven random-forest classification relying on a large set of descriptors showed the best performance. The predictive models for crystal system, Bravais lattice, point group and space group of inorganic compounds are made publicly available as easy-to-use software downloadable from https://gitlab.com/vishsoft/cosy.
