Published: March 2022

The integration between renewable materials and passive design strategies for the improvement of the built environment comfort leads to a reduction in energy consumptions and in the use of active HAVC systems. Sustainability concerns the materials employed, but also their performance: natural materials with embedded responsive properties respond to specific external stimuli, changing some of their physical or chemical properties and this represents an additional and innovative advantage in built environments. As biomimicry suggests, it is possible to take advantage of the embedded hygroscopic behavior of wood in order to create a hygromorphic composite material that passively reacts to relative humidity variations of the environment. These composites are realized with a cross-grained double-layered structure, joining a thicker veneer (active layer) and a thinner one (passive layer), in order to reproduce the principles that make pine cones scales bending after exposure to humidity variations.
The double-layered panels, called “unplywood”, can be digitally parametrized and used as a false ceiling for the passive dehumidification of an indoor environment, using only the convective motion of the humid air and the stack effect. This is particularly useful when the relative humidity excessively increases, exceeding the comfort levels.
The result is a passive dehumidification system where the timber panels act as sensors and as decorative architectural elements at the same time and contribute to improving the indoor environment from a hygrometric point of view as well as from a perceptive one.

AbstractWe introduce a new Markov Chain Monte Carlo (MCMC) algorithm with parallel tempering for fitting theoretical models of horizon-scale images of black holes to the interferometric data from the Event Horizon Telescope (EHT). The algorithm implements forms of the noise distribution in the data that are accurate for all signal-to-noise ratios. In addition to being trivially parallelizable, the algorithm is optimized for high performance, achieving 1 million MCMC chain steps in under 20 s on a single processor. We use synthetic data for the 2017 EHT coverage of M87 that are generated based on analytic as well as General Relativistic Magnetohydrodynamic (GRMHD) model images to explore several potential sources of biases in fitting models to sparse interferometric data. We demonstrate that a very small number of data points that lie near salient features of the interferometric data exert disproportionate influence on the inferred model parameters. We also show that the preferred orientations of the EHT baselines introduce significant biases in the inference of the orientation of the model images. Finally, we discuss strategies that help identify the presence and severity of such biases in realistic applications.

Published: March 2022

Abstract
Momentum feedback from isolated supernova remnants (SNRs) have been increasingly recognized by modern cosmological simulations as a resolution-independent means to implement the effects of feedback in galaxies, such as turbulence and winds. However, the integrated momentum yield from SNRs is uncertain due to the effects of SN clustering and interstellar medium (ISM) inhomogeneities. In this paper, we use spatially resolved observations of the prominent 10 kpc star-forming ring of M31 to test models of mass-weighted ISM turbulence driven by momentum feedback from isolated, nonoverlapping SNRs. We use a detailed stellar age distribution (SAD) map from the Panchromatic Hubble Andromeda Treasury survey, observationally constrained SN delay-time distributions, and maps of the atomic and molecular hydrogen to estimate the mass-weighted velocity dispersion using the Martizzi et al. ISM turbulence model. Our estimates are within a factor of two of the observed mass-weighted velocity dispersion in most of the ring, but exceed observations at densities ≲0.2 cm−3 and SN rates >2.1 × 10−4 SN yr−1 kpc−2, even after accounting for plausible variations in SAD models and ISM scale height assumptions. We conclude that at high SN rates the momentum deposited is most likely suppressed by the nonlinear effects of SN clustering, while at low densities, SNRs reach pressure equilibrium before the cooling phase. These corrections should be introduced in models of momentum-driven feedback and ISM turbulence.

Published: March 2022

Abstract
Methane is typically thought to be formed in the solid state on top of cold interstellar icy grain mantles via the successive atomic hydrogenation of a carbon atom. In the current work we investigate the role of molecular hydrogen in the CH4 reaction network. We make use of an ultrahigh vacuum cryogenic setup combining an atomic carbon atom beam with atomic and/or molecular beams of hydrogen and deuterium on a water ice. These experiments lead to the formation of methane isotopologues detected in situ through reflection absorption infrared spectroscopy. Most notably, CH4 is experimentally formed by combining C atoms with only H2 on amorphous solid water, albeit more slowly than in experiments where H atoms are also present. Furthermore, CH2D2 is detected in an experiment involving C atoms with H2 and D2 on H2O ice. CD4, however, is only formed when D atoms are present in the experiment. These findings have been rationalized by means of computational and theoretical chemical insights. This leads to the following conclusions: (a) the reaction C + H2 → CH2 takes place, although it is not barrierless for all binding sites on water, (b) the reaction CH + H2 → CH3 is barrierless, but has not yet been included in astrochemical models, (c) the reactions CH2 + H2 → CH3 + H and CH3 + H2 → CH4 + H can take place only via a tunneling mechanism, and (d) molecular hydrogen possibly plays a more important role in the solid-state formation of methane than assumed so far.
White Dwarf Photospheric Abundances in Cataclysmic Variables—II. White Dwarfs with and without a Mask
Authors: Godon Patrick , Sion Edward M. 
Published: March 2022

Abstract
Taking advantage of the now-available Gaia EDR3 parallaxes, we carry out an archival Hubble Space Telescope (HST) far-ultraviolet spectroscopic analysis of 10 cataclysmic variable systems, including five carefully selected eclipsing systems. We obtain accurate white dwarf (WD) masses and temperatures, in excellent agreement with the masses for four of the eclipsing systems. For three systems in our sample, BD Pav, HS 2214, and TT Crt, we report the first robust masses for their WDs. We modeled the absorption lines to derive the WD chemical abundances and rotational velocities for each of the 10 systems. As expected, for five higher-inclination (i ≳ 75°) systems, the model fits are improved with the inclusion of a cold absorbing slab (a curtain masking the WD) with N
H ≈ 1020–1022 cm−2. Modeling of the metal lines in the HST spectra reveals that seven of the 10 systems have significant subsolar carbon abundance, and six have subsolar silicon abundance, thereby providing further evidence that CV WDs exhibit subsolar abundances of carbon and silicon. We suggest that strong aluminum absorption lines (and iron absorption features) in the spectra of some CV WDs (such as IR Com) may be due to the presence of a thin iron curtain (N
H ≈ 1019 cm−2) rather than to suprasolar aluminum and iron abundances in the WD photosphere. The derived WD (projected) rotational velocities all fall in the range ≈100–400 km s−1, all sub-Keplerian similar to the values obtained in earlier studies.

Abstract
The level of central segregation of Blue Straggler stars has proved to be an excellent tracer of the dynamical evolution of old star clusters (the so-called “dynamical clock”), both in the Milky Way and in the Large Magellanic Cloud. The A
+ parameter, used to measure the Blue Stragglers degree of segregation, has in fact been found to strongly correlate with the parent cluster central relaxation time. Here, we have studied the Blue Straggler population of two young stellar systems in the Small Magellanic Cloud, namely NGC 339 (which is 6 Gyr old) and NGC 419 (with an age of only 1.5 Gyr), in order to study their dynamical state. Thanks to multi-epoch, high angular resolution Hubble Space Telescope observations available for both clusters, we took advantage of the stellar proper motions measured in the regions of the two systems and we selected a population of likely cluster members, removing the strong contamination from Small Magellanic Cloud stars. This enabled us to study, with unprecedented accuracy, the radial distribution of Blue Stragglers in these two extra-Galactic clusters and to measure their dynamical age. As expected for such young clusters, we found that both systems are poorly evolved from the dynamical point of view, also fully confirming that the A
+ parameter is a sensitive “clock hand” even in the dynamically young regime.
Neural Networks as Optimal Estimators to Marginalize Over Baryonic Effects

Abstract
Many different studies have shown that a wealth of cosmological information resides on small, nonlinear scales. Unfortunately, there are two challenges to overcome to utilize that information. First, we do not know the optimal estimator that will allow us to retrieve the maximum information. Second, baryonic effects impact that regime significantly and in a poorly understood manner. Ideally, we would like to use an estimator that extracts the maximum cosmological information while marginalizing over baryonic effects. In this work we show that neural networks can achieve that when considering some simple scenarios. We made use of data where the maximum amount of cosmological information is known: power spectra and 2D Gaussian density fields. We also contaminate the data with simplified baryonic effects and train neural networks to predict the value of the cosmological parameters. For this data, we show that neural networks can (1) extract the maximum available cosmological information, (2) marginalize over baryonic effects, and (3) extract cosmological information that is buried in the regime dominated by baryonic physics. We also show that neural networks learn the priors of the data they are trained on, affecting their extrapolation properties. We conclude that a promising strategy to maximize the scientific return of cosmological experiments is to train neural networks on state-of-the-art numerical simulations with different strengths and implementations of baryonic effects.
Investigating the Future Potential of an Upgraded ALMA to Image Planet-forming Disks at Sub-astronomical-unit Scales
Authors: Burrill Benjamin P. , Ricci Luca , Harter Sarah K. , Zhang Shangjia , Zhu Zhaohuan 
Published: March 2022

Abstract
In recent years, ALMA has been able to observe large-scale substructures within protoplanetary disks. Comparison with the predictions from models of planet–disk interactions has indicated that most of these disk substructures can be explained by the presence of planets with the mass of Neptune or larger at orbital radii of ≈5–100 au. Better resolution is needed to observe structures closer to the star, where terrestrial planets are expected to form, as well as structures opened by planets with masses lower than Neptune. We investigate the capabilities of a possible extension to ALMA that would double the longest baseline lengths in the array to detect and resolve disk substructures opened by Earth-mass and super-Earth planets at orbital radii of 1–5 au. By simulating observations of a family of disk models using this extended configuration in ALMA Bands 6 and 7, we show that an upgraded ALMA would detect gaps in disks formed by super-Earths as close as 1 au, as well as Earth-mass planets down to 2–3 au from the young host stars in nearby star-forming regions.

Abstract
The symbiotic X-ray binary Sct X-1 was suggested to be the first known neutron star accreting from a red supergiant companion. Although known for nearly 50 yr, detailed characterization of the donor remains lacking, particularly due to the extremely high reddening toward the source (A

V
≳ 25 mag). Here, we present (i) improved localization of the counterpart using Gaia and Chandra observations, (ii) the first broadband infrared spectrum (≈1–5 μm; R ≈ 2000) obtained with SpeX on the NASA Infrared Telescope Facility, and (iii) the J-band light curve from the Palomar Gattini-IR survey. The infrared spectrum is characterized by (i) deep water absorption features (H2O index ≈ 40%), (ii) strong TiO, VO, and CO features, and (iii) weak/absent CN lines. We show that these features are inconsistent with known red supergiants but suggest an M8-9 III–type O-rich Mira donor star. We report the discovery of large-amplitude (ΔJ ≈ 3.5 mag) periodic photometric variability, suggesting a pulsation period of 621 ± 36 (systematic) ± 8 (statistical) days, which we use to constrain the donor to be a relatively luminous Mira (M

K
= −8.6 ± 0.3 mag) at a distance of

3.6

−
0.7

+
0.8

kpc. Comparing these characteristics to recent models, we find the donor to be consistent with a ≈3–5 M
⊙ star at an age of ≈0.1–0.3 Gyr. Together, we show that Sct X-1 was previously misclassified as an evolved high-mass X-ray binary; instead, it is an intermediate-mass system with the first confirmed Mira donor in an X-ray binary. We discuss the implications of Mira donors in symbiotic X-ray binaries and highlight the potential of wide-field infrared time-domain surveys and broadband infrared spectroscopy to unveil their demographics.

Published: March 2022

В статье проанализированы проблемы, возникающие при применении ст. 280 Уголовного кодекса Российской Федерации, устанавливающей ответственность за совершение публичных призывов к осуществлению экстремистской деятельности. На сегодняшний день данная норма уголовного закона сконструирована сугубо просто: наименование и содержание диспозиции части 1 полностью совпадают. Представляется, что в ней отсутствует необходимое понятийное содержание, что порой приводит к неправомерному привлечению к уголовной ответственности. Автором предложены возможные пути решения возникающих проблем, в частности речь идет о необходимости внесения изменений в Уголовный кодекс Российской Федерации и Кодекс об административных правонарушениях. Рассмотрена судебная практика привлечения к ответственности, приводится статистика совершения преступлений по данной норме.
In this article the author analyzes the problems arising in the law enforcement sphere when applying Art. 280 of the Criminal Code of the Russian Federation, which establishes responsibility for making public appeals extremist activities. Today this provision of the criminal law looks purely simple (the name and content of the disposition of part 1 completely coincide). According to the author the norm lacks the necessary conceptual content, which sometimes leads to illegal bringing to criminal responsibility. The author proposes possible solutions to emerging problems, in particular, the introduction of amendments to the Criminal Code of the Russian Federation and the Code of Administrative Offenses. The judicial practice of bringing to responsibility and statistics of crimes committed according to this norm are presented.
