The goal of this study was to examine the influence of trading volume, market value added, dividend payment ratio and systematic risk on stock return of businesses listed on the Indonesia Stock Exchange in the construction and building sub-sector. Purposive sampling was used, with 35 samples drawn from financial reports covering the years 2011-2017. The analytical approach used was panel data regression analysis. trading volume and market value added have a substantial impact on stock returns. Meanwhile, dividend payment ratio and systematic risk have no effect on stock returns. Construction and building industry sub-sector businesses were chosen as a sample in this study. Furthermore, there are few comparable studies that employ samples from industrial construction and building sub-sector businesses. The sample was chosen because it is seen as a constant contributor to the country's economic success. This is evident in the long-term development of government infrastructure, such as toll roads, airports, public housing, and other public amenities. According to Central Statistics Agency (BPS) study, the construction sector is one of the three key contributors to Indonesia's economic development. This is what makes this study interesting. Researchers should find the research useful in broadening their knowledge and skills on the subject issue, debating the research item, and applying principles learnt in lectures. Companies are required to provide information that would assist them in developing strategic plans and making decisions that will improve their performance. a limited number of samples and a short time period (just 2011 to 2017), which is most likely leading the data computation findings to be less than optimal Furthermore, not all firms provide dividends on a yearly basis.

Le Sezioni unite della Corte di cassazione si sono recentemente pronunciate in ordine alla questione relativa alla individuazione dei limiti dell’efficacia retroattiva della disposizione ex art. 578-bis c.p.p. Il quesito oggetto di rimessione concerne l’applicabilità, o meno, di detta norma del codice di rito anche con riferimento alla confisca per equivalente disposta in relazione a un fatto di reato commesso anteriormente alla entrata in vigore dell’art. 1, comma 4, lett. f), legge 9 gennaio 2019, n. 3, che ha inserito nell'art. 578-bis c.p.p. le parole «o la confisca prevista dall’art. 322-ter cod. pen.». Alla base del contrasto che ha reso necessario l’interpello delle Sezioni unite vi sono le diverse interpretazioni offerte dalle pronunce delle Sezioni semplici in ordine al rapporto tra la natura “processuale” della disposizione di cui all'art. 578-bis c.p.p., come tale soggetta al principio tempus regit actum, e il carattere afflittivo della confisca per equivalente.

The aim of the work is to investigate the effect of compound feeds with different levels of protein on the growth of juveniles of the Australian red claw crayfish Cherax quadricarinatus.   Used methods: To solve this problem, two experiments were carried out in the aquariums of aquaculture invertebrate department at VNIRO: the first was on juveniles weighing 0.017 ± 0.004 g and 0.87 ± 0.08 mm long; the second one was on juveniles weighing 0.31 ± 0.14 g and 23.7 ± 3.9 mm long. The duration of the experiments was 30 and 40 days, respectively. Feeding of juveniles was carried out with three variants of compound feed recipes with an estimated protein content of 25 %, 35 % and 45 %. The main part of the formulations consisted of components of plant origin. Tetra Wafer Mix food for fish and crustaceans (Germany) with a protein content of 45 % was used as a control. The duration of the experiments was 30 and 40 days, respectively. Feeding of juveniles was carried out with three variants of compound feed recipes with an estimated protein content of 25 %, 35 % and 45 %. The main part of the formulations consisted of components of plant origin. Tetra Wafer Mix food for fish and crustaceans (Germany) with a protein content of 45 % was used as a control.   Newness: Development of a feed formulation for rearing juveniles of the Australian red claw crayfish in recirculating aquaculture systems (RAS).   Results: These experiments showed that the growth rate of juvenile Australian red claw crayfish is directly dependent on the proportion of protein in the feed. It was established that the relative content of protein in the muscles of crayfish depends on its content in compound feed. An analysis of our own and published data indicates that feeds with protein content below 35 % cannot be recommended for growing of juveniles’ Australian red claw crayfish. Feeds with a protein content of 45 % are optimal for the growth of juveniles. It was established that the effectiveness of compound feeds depends not only on the protein content and energy value, but also on their taste attractiveness.   Practical significance: The obtained results will be used in the development of mixed feed for juveniles Australian red claw crayfish.

The aim of the work was to study the effect of compound feeds with full or partial replacement of fish oil with vegetable oils on the composition of tissues and growth perfomance of rainbow trout.   Method of chemical analyses was used for the estimation of nutritional value of the feed. To determine the fatty acid composition of the total lipids of feed and muscle tissue of trout, methyl esters of fatty acids were analyzed on a Crystal 5000.2 chromatograph. To assess the effect of compound feeds on fish, a number of fish-breeding and biological indicators were determined.

   The novelty of the study is associated with modeling the optimal ratio of fish oil, rapeseed and soybean oils in fish diets.   As a result of the research, it was found that the highest growth rates and survival at lower feed costs were found in fish grown on diet without replacing fish oil and diet with a mixture of fish oil, rapeseed and soybean oils in a ratio of 4:6:5. Replacing fish oil with vegetable oils in feed recipes did not adversely affect the chemical composition of fish muscle tissue. Due to the elongation and desaturation processes occurring in the tissues of rainbow trout, the inclusion of rapeseed and soybean oils in the compound feed did not lead to a decrease in the amount of eicosapentaenoic and docosahexaenoic fatty acids.   The practical significance of the work lies in obtaining new diets for compound feeds for valuable fish species, providing opportunities for effective cultivation of rainbow trout with specified quality characteristics.
On the regulation of the fishery taking into account its effectiveness using the example of pollock in the northern part of the Sea of Okhotsk
Authors: Voloshin G. A. , Artemenkov D. V.
Published: December 2022

The purpose of this work is to consider the question of the criteria for the effectiveness of fishing during the year using the example of pollock of the Severo-Okhotomorskaya subzone.

Materials and methods: The work analyzed the effectiveness of the fishery based on the data of the fishery and statistical information of the Center for the Fishery Monitoring and Communications System of the Federal Agency for Fishery. The main indicators for the analysis were: pollock production by month, production per vessel-day of fishing, number of vessels per vessel, number of vessels per vessel-day of fishing, share of production beheaded + 25 in total production beheaded. The highly profitable pollock fishery of season “A” is observed in February, March and April, which is confirmed by reliably different indicators of the average production volume and the volume of production per ship-day of fishing during these months relative to season “B” (at p < 0.001).

The results of the study: The results of the analysis of the considered indicators may indicate such reasons as the suboptimal amount of the total allowable catch, the development of which requires increased costs and, as a result, reduces the economic efficiency of the fishery, suboptimal schemes for the arrangement of the fleet.

Practical significance: The results obtained during the work indicate the need to take into account economic and social criteria when assessing the efficiency of the exploitation of reserves of aquatic biological resources, which are currently not taken into account in fisheries management.
Hardware Accelerated Magnetic Field Calculation Approach for Circular Coils With Rectangular Cross Section
Authors: Dobrota Davor , Sočec Nikola , Vrabac Lara , Bojanjac Dario
Published: December 2022

In this paper, we present a performance-oriented approach for calculating magnetostatic fields produced by circular coils. Those include the magnetic vector potential, magnetic flux density and magnetic field gradient, together addressed as fields.

Many inductive elements used in a wide range of applications can be modeled as circular coils with a rectangular cross-section, and this is reflected in the number of papers on the subject. Instead of extensively utilising analytic methods, we focused on achieving maximum performance by efficiently implementing the Gauss-Legendre quadrature and applying it to expressions which are simple with respect to computational intensity. To properly leverage this, we implemented our approach in the C++ programming language. The CUDA framework enabled us to utilise the full power of Nvidia graphics cards, especially when multiple coils are present. Our approach can also be used from Python and MATLAB with a small performance penalty.

Performance of field compute methods is primarily expressed in the number of field values calculated every second. Processor performance was tested on multiple systems and exceeded one million points per second on all of them. Graphics card performance is particularly noteworthy, with over 5 million magnetic flux density values computed every second for a system of 100 coils, placing effective performance at more than 500 million points per second on a contemporary laptop graphics card.

The meticulous implementation, available on GitHub, and unique performance are the highlights of our work.

Authors: Sumsuzzoha Dr. S.M. , Sattar Dr. Md. Abdus , Das Dr. Arun Kumar , Zaman Dr. Shaila
Published: December 2022

Background: Acne vulgaris is a common dermatological problem. Acne is most commonly found in adolescents, caused by increased androgens in both sexes. It is usually caused due to Propionibacterium acnes. Minocycline is a newly introduced drug in treating acne vulgaris. On the other hand, it is assumed that azithromycin having a long half-life like can be very effective with better compliance in treating acne vulgaris. But we have not enough research-based comparative data regarding this issue. Objective: The objective of this study was to compare the efficacy and safety of azithromycin pulse therapy with minocycline in treating acne vulgaris. Methods: This was a prospective, comparative study and was conducted in Department of Dermatology, Naogaon Medical College, Naogaon, Bangladesh, during the period from January 2021 to December 2021. In total 80 patients with moderate-to-moderately severe (Grade II and III), acne vulgaris were included in the study population. Patients were randomly assigned to two treatment groups of group A & group B respectively. In group A, there were 25 patients received 500 mg azithromycin once a day for 3 days per week as pulse therapy along with 0.05% topical tretinoin for 3 months whereas in group B, there were another 25 patients received 50 mg minocycline twice a day along with 0.05% topical tretinoin for 3 months. All data were processed, analyzed, and disseminated by SPSS version 23.0 and MS Office program. Results: In this study, group A (Azithromycin) between baseline and final score distribution we found a significant correlation (P=0.023). On the other hand, in group B we did not find any significant correlation (P=0.073). In analyzing the changes in severity score of acne from baseline to the final assessment of both groups we observed, in group A at baseline 15%, 38%, and 48% of participants had the score points 2, 3, and 4 respectively whereas in the final stage 63%, 30%, and 8% participants had the score point 1, 2 and 3 respectively. So, in group A between baseline and final score distribution, we found a significant correlation (P=0.023). On the other hand, in group B at baseline 10%, 40%, and 50% of participants had the scored points 2, 3, and 4 respectively whereas in the final stage 65%, 28%, and 8% of participants had the score point 1, 2 and 3 respectively. In group B between baseline and final score distribution we found P value 0.073. Conclusion: In this study, the efficacy of both azithromycin pulse therapy and minocycline was found satisfactory. But as per the findings regarding the safety profiles, we can conclude that minocycline is safer than azithromycin pulse therapy in treating acne vulgaris.

This research work focuses on the fabrication and study of a series of nanocomposites consisting of two types of hydroxyapatite (HA), obtained by precipitate (HAP) and sol–gel (HAG) methods, and a boro-silico-phosphate bioglass. The microstructure and chemical, mechanical, and biological properties as functions of three factors, namely (i) the type of hydroxyapatite, (ii) glass content, and (iii) sintering temperature, were investigated. It was found that all of these factors affect the final composition and microstructure, especially, porosity, which shows significantly lower values for HAP-based composites than for HAG-based ones and higher values for higher glass content. This, in turn, has an impact on the microhardness, which exhibits a strong correlation with porosity, as well as on the mineralization capability and cell viability due to the different dissolution rate.
Distinguishing Dark Matter, Modified Gravity, and Modified Inertia with the Inner and Outer Parts of Galactic Rotation Curves
Authors: Chae Kyu-Hyun
Published: December 2022

The missing gravity in galaxies requires dark matter, or alternatively a modification of gravity or inertia. These theoretical possibilities of fundamental importance may be distinguished by the statistical relation between the observed centripetal acceleration of particles in orbital motion and the expected Newtonian acceleration from the observed distribution of baryons in galaxies. Here predictions of cold dark matter halos, modified gravity, and modified inertia are compared and tested by a statistical sample of galaxy rotation curves from the Spitzer Photometry and Accurate Rotation Curves database. Modified gravity under an estimated mean external field correctly predicts the observed statistical relation of accelerations from both the inner and outer parts of rotation curves. Taken at face value there is a

difference between the inner and outer parts on an acceleration plane which would be inconsistent with current proposals of modified inertia. Removing galaxies with possible systematic concerns such as central bulges or special inclinations does not change this trend. Cold dark matter halos predict a systematically deviating relation from the observed one. All aspects of rotation curves appear to be most naturally explained by modified gravity.
The Dust Cycle on Mars at Different Orbital Distances from the Sun: An Investigation of the Impact of Radiatively Active Dust on Land Planet Climate
Authors: Hartwick Victoria L. , Haberle Robert M. , Kahre Melinda A. , Wilson Robert J.
Published: December 2022

The dust cycle is the dominant driver of meteorology and climate on present-day Mars. Despite this, few studies have investigated the impact of dust interacting with incoming stellar radiation on the climate, habitability, and potential spectral signature of Mars-like exo-land planets. Dust availability is positively correlated with increasing soil aridity and therefore dust has significant potential to modify dynamics on dry land planets. In this work, we use an advanced Mars general circulation model to study the coupling between radiatively active dust and land planet climate at different stellar heating rates or planetary orbits. We find that radiatively active dust can significantly modify land planet climate. At Earth orbit, dust with optical properties similar to present-day Mars warms the planetary surface above 273 K and augments both the zonal mean circulation and the thermal tide, and in particular the semidiurnal component. As dust accumulates, peak heating rises off the planetary surface and the most active regions of dust lifting shift from the summer to winter hemisphere. Simulated spectra are nearly featureless across all wavelengths. We find that in order to accurately assess the climate and habitability of land planets it is critical to carefully consider that potential atmospheric dust budget and its radiative impact.

Published: December 2022

Mid-infrared silicate dust bands observed in heavily obscured active galactic nuclei (AGNs) include information on the mineralogical properties of silicate dust. We aim to investigate the mineralogical picture of the circumnuclear region of heavily obscured AGNs to reveal obscured AGN activities through the picture. In our previous study, we investigated the properties of silicate dust in heavily obscured AGNs, focusing on the mineralogical composition and the crystallinity with Spitzer/IRS 5.3–12 μm spectra. In this study, we model the full-range Spitzer/IRS 5–30 μm spectra of 98 heavily obscured AGNs using a one-dimensional radiative transfer calculation with four dust species in order to evaluate wider ranges of the properties of silicate dust more reliably. Comparing fitting results between four dust models with different sizes and porosities, 95 out of the 98 galaxies prefer a porous silicate dust model without micron-sized large grains. The pyroxene mass fraction and the crystallinity are overall consistent with—but significantly different from—the previous results for the individual galaxies. The pyroxene-poor composition, small dust size, and high porosity are similar to newly formed dust around mass-loss stars as seen in our Galaxy, which presumably originates from the recent circumnuclear starburst activity. The high crystallinity on average suggests dust processing induced by AGN activities.
The High-ionization IR Fine Structure Lines as Bolometric Indicators of the AGN Power: Study of the Complete 12 μm AGN Sample
Authors: Spinoglio Luigi , Fernández-Ontiveros Juan Antonio , Malkan Matthew A.
Published: December 2022

The high-ionization mid-IR lines, excited in the narrow-line regions of active galactic nuclei (AGN), barely affected by stellar excitation and dust extinction, trace the AGN bolometric power. We used the complete 12 μm sample of Seyfert galaxies, for which 100/116 objects have reliable 2–10 keV observations. The [Ne v] and [O iv] mid-IR lines linearly correlate with several AGN bolometric indicators (intrinsic 2–10 keV and observed 14–195 keV X-ray emission, compact nuclear 12 μm emission, [O iii] λ5007 Å line emission) in terms of both flux and luminosity. No evidence of systematic differences in these correlations is found among the Seyfert populations, including types 1 and 2 and Compton-thick and Compton-thin AGN. Nevertheless, we find that a sequence of high-to-low Eddington ratios together with strong-to-weak line excitation (traced by the [O iv]/[Ne ii] line ratio) encompasses from type 1 through type 2 AGN to low-ionization nuclear emission-line region galaxies, showing intrinsic differences in these three AGN populations. A positive correlation between the black hole accretion rate (BHAR) and the star formation rate (SFR) is found, but no correlation between the specific SFR and the ratio BHAR/M
BH, simply reflecting the fact that the more massive a galaxy is, the more it is forming stars and feeding its central black hole. The JWST, just beginning operations, will allow large samples of AGN to be observed in these lines in the nearby universe (z < 0.9).
Relation of Observable Stellar Parameters to Mass-loss Rate of AGB Stars in the LMC

Published: December 2022

Using the data set of Riebel et al. for 6889 pulsating AGB stars in the LMC, we have derived formulae for mass-loss rate as a function of luminosity and pulsation period, or luminosity and mass, in three ways, for each of five subsets of data: fundamental-mode oxygen-rich stars, first-overtone-mode oxygen-rich stars, fundamental-mode carbon stars, first-overtone-mode carbon stars, and extreme carbon stars. Using the distribution of the stars in period versus luminosity and mass versus luminosity, we are able to derive a power-law fit to the dependence of mass-loss rate on those quantities. This results in formulae that reproduce observed mass-loss rates and are in general agreement with the expectation from mass-loss models that the mass-loss rate is highly sensitive to luminosity, mass, and pulsation period. In the process of carrying out this analysis we have found radius–mass–luminosity relations and examined pulsation–mass–radius relations using published evolutionary and pulsation models. These allow us to derive mass and radius from the observed quantities luminosity and pulsation period. We also derived new mass-loss rate versus color relations.
Self-similar Solution of Rotating Eruptive Outflows on Its Equatorial Plane
Authors: Ko Takatoshi , Fujisawa Kotaro , Shigeyama Toshikazu
Published: December 2022

We construct axisymmetric self-similar solutions of transonic outflows emanating from a point source including the effect of the rotation. The solutions are constructed exclusively on the equatorial plane. The features of solutions are determined by three parameters: the adiabatic index γ, the dimensionless coordinate of the transonic point, and the dimensionless azimuthal velocity at the transonic point. We classify the solutions into five groups according to asymptotic behaviors. We find that the behaviors of the self-similar solutions change at γ = 11/9. In addition, some solutions show double-power-law density profiles, which are usually seen in ejecta from a binary merger or nova-like explosion. Thus, our self-similar solutions can be applied not only to the outflow blowing from the central spinning objects but also to the ejecta erupted from the binary merger or nova-like explosion.

The aim of this study was to create an overview of the Czech Armed Forces' development in approach to environmental protection from 1989 to 2022. Using the methods of analysis, synthesis and comparison of the Czech, EU´s and NATO´s environmental legislation, we created a comprehensive and previously unpublished overview of environmental protection within the Czech Armed Forces. Found outputs were set into illustrations depicting the activities in the environmental field with internal links between civil legislation, EU's requirements, and NATO's policy in chronological order. We conclude that the year 2000 represents a key milestone from which the approach to environmental protection have stagnated. Among the reasons for the stagnation, we identify commanders' concerns about "green approach" to troop training and the lack environmental education within defence department.
Holotype sequencing of Silvatares holzenthali (Trichoptera, Pisuliidae)

Published: December 2022

While “DNA barcodes” are often provided, the whole mitochondrial and nuclear genome are rarely considered to be included in species descriptions. This is unfortunate because whole genome sequencing of holotypes allows eternal genetic characterization of the most representative specimen for a given species. Thus, de novo genomes are invaluable added resources and important additional diagnostic characters in species descriptions, provided the integrity of the holotype specimens remains intact. Here, we used a minimally invasive method to extract DNA of the type specimen of the recently described caddisfly species Silvatares holzenthali (Trichoptera, Pisuliidae) from the Democratic Republic of the Congo. A low-cost next generation sequencing strategy was used to generate the complete mitochondrial and draft nuclear genome of the holotype. The data in its current form is an important extension to the morphological species description and valuable for phylogenomic studies.
Towards a Roadmap for Advancing the Catalogue of the World’s Natural History Collections

Published: December 2022

Natural history collections are the foundations upon which all knowledge of natural history is constructed. Biological specimens are the best documentation of variation within each species, increasingly serve as curated sources for reference DNA, and are frequently our only evidence for historical species distribution. Collections represent an enormous multigenerational investment in research infrastructure for the biological sciences, but despite this importance most of the holdings of these institutions remain invisible on the Internet, inaccessible to taxonomists from other countries and hidden from computational biodiversity research.

Although comprehensive digitisation of the complete holdings of each natural history collection is the long-term goal, this is an expensive and labor-intensive task and will not be completed in the near future for all collections. However, many benefits could quickly be achieved by publishing high-quality metadata on each collection to increase its visibility, provide the foundations for further digitisation and enable researchers to discover and communicate with collections of interest.

This paper summarises the results from a consultation activity carried out in 2020 as part of the SYNTHESYS+ (Synthesys of Systematic Resources), “Developing implementation roadmaps for priority infrastructure areas as part of cooperative RI for biodiversity” project. This consultation was primed through an ideas paper, and introductory webinars and conducted as a facilitated two-week online multilingual discussion around 26 topics grouped under four broad headings (Users, Content, Technology and Governance). The results of these discussions are summarised here, along with the wider context of existing and planned initiatives.
La linguistique historique et l’expressivité : les avatars d’une notion
Authors: Combettes Bernard
Published: December 2022

Cette contribution a pour objectif de décrire la place qui a été accordée au concept d’ expressivité en linguistique historique, en particulier en ce qui concerne la linguistique française. Après avoir remarqué que cette notion est déjà en germe chez certains grammairiens de l’époque classique, on observera la situation au début du xx e  siècle, avec l’examen des idées de Bally, et on s’attachera à déterminer la place qu’occupe la notion d’ expressivité dans l’œuvre de Meillet, et quel rôle elle joue pour lui dans l’évolution de la langue. On étudiera ensuite comment les travaux plus récents sur la grammaticalisation, à partir des années 70, mettent en œuvre une notion très proche de la notion d’ expressivité , la notion d’i ntersubjectivité et comment cette dernière se trouve exploitée de deux manières, selon que l’accent est mis sur la dimension communicationnelle ou sur la dimension énonciative.

The purpose of this study was to evaluate the impact of opioid-limiting legislation on perioperative opioid prescriptions in total knee arthroplasty. The hypothesis was that opioid legislation has reduced opioid prescription filling above levels anticipated by national trends. This study retrospectively evaluated opioid prescription filling for all patients undergoing total knee arthroplasty in a commercially available insurance database between 2010 and 2018 (n=1,068,764). Initial discharge and 90-day cumulative oxycodone 5-mg equivalents filled were tabulated. Opioid prescription filling was evaluated over time and between states with and without opioid-limiting legislation using analysis of variance and multivariable linear and logistic regression. States with and without opioid legislation had significant reductions in initial and cumulative opioid prescription filling volume (all
P
<.001). However, the magnitude of this reduction was larger in states with opioid legislation. Legislation targeting duration and volume had the largest impact on initial post-act opioid prescription filling volume compared with states without legislation in an estimated “pre-act” time frame. Legislation targeting duration and volume and no specific target had the largest impact on cumulative post-act opioid prescription filling volume. States without legislation still had large, significant reductions in filling volume, but the magnitude was not as great as in states with opioid legislation. States with and without opioid legislation had significant decreases in initial and cumulative opioid prescription filling volume. However, the magnitude of reduction was larger in states that enacted legislation. Younger age, pre-operative opioid use, and higher comorbidity burden were associated with greater opioid use postoperatively. [

A spatio-temporal deep learning model for short-term bike-sharing demand prediction
Authors: Jia Ruo , Chamoun Richard , Wallenbring Alexander , Advand Masoomeh , Yu Shanchuan , Liu Yang , Gao Kun
Published: December 2022

Bike-sharing systems are widely operated in many cities as green transportation means to solve the last mile problem and reduce traffic congestion. One of the critical challenges in operating high-quality bike-sharing systems is rebalancing bike stations from being full or empty. However, the complex characteristics of spatiotemporal dependency on usage demand may lead to difficulties for traditional statistical models in dealing with this complex relationship. To address this issue, we propose a graph-based neural network model to learn the representation of bike-sharing demand spatial-temporal graph. The model has the ability to use graph-structured data and takes both spatial- and temporal aspects into consideration. A case study about bike-sharing systems in Nanjing, a large city in China, is conducted based on the proposed method. The results show that the algorithm can predict short-term bike demand with relatively high accuracy and low computing time. The predicted errors for the hourly station level usage demand prediction are often within 20 bikes. The results provide helpful tools for short-term usage demand prediction of bike-sharing systems and other similar shared mobility systems.

Model for self-assembly of Br–H and Br–Br bonded Br4Py molecules
Authors: Ibenskas Andrius , Tornau Evaldas E. , Šimėnas Mantas
Published: December 2022

A model, based on the pairwise intermolecular halogen–hydrogen (Br–H) and halogen–halogen (Br–Br) bonding, is proposed to describe the self-assembly of Br4Py molecules into two different planar structures (Phase I and Phase II). The pair bonding interactions are calculated by the density functional theory for the two-molecule and four-molecule clusters. It is shown that about 60% of bonding strength is due to the electrostatic Br(top)–Br(belt) interactions, while the remaining originates from Br–H interactions. The obtained values of pair interactions are further used for Monte Carlo calculations. The model for these calculations is proposed on a square lattice. The two main pair interactions are needed for the emergence of the Phase I ordering, while the Phase II ordering is obtained using a single interaction. The obtained results explain the emergence of both phases.
