Background
The global burden of anxiety and depression has created an urgent need for scalable approaches to increase access to evidence-based mental health care. The Screening and Treatment for Anxiety and Depression (STAND) system of care was developed to meet this need through the use of internet-connected devices for assessment and provision of treatment. STAND triages to level of care (monitoring only, digital therapy with coaches, digital therapy assisted by clinicians in training, and clinical care) and then continuously monitors symptoms to adapt level of care. Triaging and adaptation are based on symptom severity and suicide risk scores obtained from computerized adaptive testing administered remotely.

Objective
This article discusses how the STAND system of care improves upon current clinical paradigms, and presents preliminary data on feasibility, acceptability, and effectiveness of STAND in a sample of US-based university students.

Methods
US-based university students were recruited and enrolled in an open trial of the STAND system of care. Participants were triaged based on initial symptom severity derived from a computerized adaptive test and monitored over 40 weeks on anxiety, depression, and suicide risk to inform treatment adaptation and evaluate preliminary effectiveness.

Results
Nearly 5000 students were screened and 516 received care. Depression and anxiety severity scores improved across all tiers (P<.001 in all cases). Suicide risk severity improved in the highest tier (ie, clinical care; P<.001). Acceptability and feasibility were demonstrated.

Conclusions
STAND is a feasible and acceptable model of care that can reach large numbers of individuals. STAND showed preliminary effectiveness on all primary outcome measures. Current directions to improve STAND are described.

Published: May 2023

Introduction. The most popular binders for the concrete production are inorganic binders. Composite binding agents (CB) based on Portland cement are increasingly being used to produce high-quality concretes, improve the efficiency of cement use in concrete, as well as to solve the problem of energy and resource saving by reducing the amount of clinker inthe cement composition.
Materials and methods. The properties of a composite binder consisting of Portland cement, alumina cement, natural gypsum and an active mineral additive, were studied. The Box – Wilson experiment design method was used. To determine the standard consistency of the cement paste, the standard test method was chosen according to GOST 310.3–76.The research was carried out in the laboratory of the Department of Building Materials Science of Moscow State University of Civil Engineering.
Results. It was found that with the introduction of additives normal density of the cement paste increases. This is explained by the fact that the composition of the complex additive includes tripoli and alumina cement. Tripoli is a natural porous rock with a highly developed surface. Alumina cement has a great influence on the normal density and setting time as it reacts very quickly to form new hydration compounds in the first minute from the start of mixing the binder with water.The dependence of normal density on the quantitative content of additives is presented as a regression equation and surface image.
Conclusions. Based on the results of this study, in the future the authors will continue to study the properties of binders based on a complex expanding and pozzolanic addition.

Introduction. At the current stage of implementation of the Strategy for development of the construction industry and housing and communal services of the Russian Federation for the period till 2030 there is a need for management of unique innovation projects on creation of hi-tech construction products and products for which there is no historical retrospective and sufficient experience in management of such projects: development and creation of composite materials, metal powder for the additive manufacturing, self-healing concrete, etc. Therefore, the problem of developing a mathematical model forthe creation of hi-tech building products is relevant.
Materials and methods. Working out the model, the methods of Markov and semi-Markov systems modelling and methods of programmed planning that have proven to be good at modelling the stages of the life cycle when creating high-tech and unique samples of special purpose machinery were applied.
Results. A model of creation of hi-tech building products, which allows to model and manage the stages of the product life cycle, has been developed. The results of numerical modelling are given. The results of the modelling have shownthe possibility of effective management of the stages of the life cycle of high-tech products. The developed model is a part of scientific and methodical apparatus for end-to-end modelling of basic stages of life cycle of high-tech building production. In this case, depending on the specific problem to be solved, the modelling of individual stages of the life cycle can be carried out with different levels of detail using those or other models of life cycle stages. For certain types of created products, some of the life cycle stages may be excluded from the general model or, on the contrary, added to the general model. The model developed in the article can serve as a means of obtaining additional input data to be used for information modelling with the help of BIM technologies.
Conclusions. The developed model adequately enough describes real processes of product development and creation. The model is not demanding for quality and completeness of input data.

Authors: Glazkova Valeria V. , Gospodarik Catherine G. 
Published: May 2023

Introduction. The decrease in the efficiency of the heat supply industry, caused by a high degree of deterioration of the main production assets, creates the necessity to modernize the sphere, which requires the involvement of a significant amount of investment resources. One of the effective tools contributing to this process is public-private partnership (PPP), which includes positive aspects both for state and municipal authorities as well as for business representatives.
Materials and methods. Theoretical and methodological basis of the study was provided by the works of domestic researchers on the implementation of capital investments in the development of heat supply. Methods of theoretical research were used to analyze the practice of implementation of projects to modernize the heat supply using PPP, modeling stages of the concession agreements, as well as methods of empirical research in terms of comparing the forms of interaction between government and business in the joint implementation of projects for the development and modernization of the heat supply.
Results. The study of professional opinions of Russian researchers on the issue of insufficient effectiveness ofthe implementation of the public-private partnership instrument in the field of housing and communal services and energy, including heat supply, has enabled the formation of a list of problem areas in order to identify areas for their solutions.
Conclusions. The presented successfully implemented cases of modernization of heat supply systems in the Russian regions, which have been implemented through concession agreements between the authorities and business representatives, allowed to confirm the thesis that the concession is one of the best forms of PPP implementation in the field of heat supply. According to the prospective estimates of the National PPP Centre, about 130 PPP projects in the housing and utilities sector may be launched already by 2024, and the value of investments may exceed RUR 230 billion.

Published: May 2023

Bipolar disorder is a brain illness that causes mood, energy, and ability to function variations. Bipolar illness patients have extreme emotional states that often occur over a period of days to weeks, referred to as mood episodes. Manic/hypomanic (abnormally cheerful or angry mood) or depressed (sad mood) mood episodes are classified. People with bipolar disorder frequently have periods of neutral mood. People with bipolar disorder can live long and productive lives if they are treated. The management of BD may be summarized into 2 phases, acute treatment and long-term prevention. Lithium was observed to have a unique therapeutic profile, including mood-stabilizing effects, as well as anti-suicidal and neuroprotective properties.13 It is available in many different salt forms, namely lithium carbonate, lithium citrate, lithium chloride, and lithium sulfate. A meta-analysis discovered that a combination regimen of haloperidol, olanzapine, risperidone, and quetiapine was substantially more effective in treating BD manic episodes than monotherapy with a mood stabiliser, but the combination regimen was less well tolerated than monotherapy.

Samples of the stoichiometric composition La3Pb0.1Ga1.6Sе7 and Pr3Pb0.1Ga1.6Sе7, weighing 0.8 gram each, were prepared by fusing components of semiconductor purity in vacuumed quartz containers to a residual pressure of 10-2 Pa. The synthesis was carried out in a muffle furnace with software control of MP-30 technological processes. The maximum temperature of synthesis is 1100°C, homogenizing annealing lasted 240 hours at temperature of 500°C.
The diffraction patterns for X-ray phase analysis were recorded at a DRON 4-13 diffractometer for 2Q range of 10-100° (CuKα radiation, scan step 0.02°, 20 s exposure in each point). Data processing and the determination of the crystal structure utilized WinCSD software package. Visualization of the crystal structure, stacking and coordination polyhedra was performed using the VESTA program.
The crystal structure of the selenides La3Pb0.1Ga1.6Sе7 and Pr3Pb0.1Ga1.6Sе7 was studied by the X-ray powder diffraction method and its belonging to the hexagonal crystal system was established (space group P63). The refinement of atom coordinates and isotropic temperature displacement parameters in this model yielded satisfactory values of fit factors. Analysis of hkl reflex indices and their intensity indicates that the structural of La(Pr)3Pb0.1Ga1.6Sе7 compounds belong to the structural type La3CuSiS7 (space group P63; a = 1.028 nm, c = 0.575 nm)
Crystal structure of selenides La3Pb0.1Ga1.6Se7 (a = 1.05595(4) nm, c = 0.63868(3) nm, RI = 0.0983, Rp = 0.1672) and Pr3Pb0.1Ga1.6Se7 (a = 1.03727(6) nm, c = 0.63772(5) nm, RI = 0.0868, Rp = 0.2286) was studied by X-ray powder method. It was established that the structure of the synthesized selenides belongs to the structural type La3CuSiS7 (SG P63; PS hP24). In their structure, R = La(Pr) atoms are localized in site 6c and, together with selenium atoms, form trigonal prisms with one additional atom [R 1Se13Se23Se3]. Atoms of statistical mixtures M1 (0.64 Ga + 0.09 Pb) and M2 (0.58 Ga + 0.11 Pb), concentrated in site 2a, form octahedra [M1 6Se2] and [M2 6Se2]. These octahedra are interconnected by faces and form columns in the direction of the c axis. The Ga (site 2b) atoms are surrounded by four selenium atoms. The formed tetrahedra are oriented in the direction of the c axis and are isolated from each other. Gallium-containing selenides La3Pb0.1Ga1.6Sе7 and Pr3Pb0.1Ga1.6Sе7 based on lanthanum and praseodymium are promising chalcogenides based on which materials for nonlinear optics and thermoelectricity can be created.

Cultural Distances and Its Association to Time Spent on Conflicts
Authors: Dirrler Phyllis , Podruzsik Szilard 
Published: May 2023

Abstract
Conflict costs can be used to determine conflict outcomes and can be measured among others in terms of lost time. So far, no study has investigated the effects of cultural distances on conflict costs. Our study tries to add new findings by investigating the influence of cultural distances on internal indirect conflict costs. A survey with 226 participants was conducted to measure the time spent on conflicts. Each participant reported on a conflict situation he or she was personally involved in. We used linear regression analysis to test our hypotheses. We did not find support for our hypotheses that the larger a cultural distance was, the more time was spent on a conflict. According to our study, cultural distances do not explain conflict costs and it cannot be proven that the greater a distance, the higher the conflict costs. In a more globalized world, it is positive that despite great cultural distances, time spent on conflicts does not increase. This can encourage leaders to capture the benefits of diversity, whereas the consequences on at least some conflict costs are low.

Corn is a strategic agricultural commodity in Central Java Province because this plant is the second main food crop commodity after rice. Evaluation of agro-climate suitability aims to assess suitable areas based on climatic conditions and efforts to overcome climate-limiting factors in order to achieve optimal productivity in corn cultivation. Satellite imagery can be used to overcome the lack of density of climate stations, which are the source of data for climate suitability evaluation. This study aims to validate GSMaP satellite rainfall data and Terra MODIS satellite air temperature data against BMKG observation data, create a distribution map of climatic conditions, and create a distribution map of agro-climate suitability classes based on GIS for maize in Central Java Province. This study uses rainfall and temperature data from 30 BMKG observation points and satellite imagery data for 20 years (2001–2020). The correlation values, RMSE, and MBE were calculated to validate satellite rainfall and air temperature data with observed rainfall and air temperature. Satellite data correction calculations are used to fill in the data at points without observation. The validation results show that the satellite data is valid and that there is a pattern of conformity with the observational data. Central Java province has an annual rainfall of 1,500 mm/year to 6,000 mm/year, an average annual temperature of 24.9oC to 28.1oC, and three to nine months of wet months. In some areas, the agro-climate suitability class for maize plants was in the moderately suitable category (S2wa, tc) with an area of 156,302 ha, marginally suitable (S3wa) with an area of 1,277,813 ha, and not suitable (Nwa) with an area of 2,008,673 ha.
