Authors: Dewi P A R K , Kridarso E R , Iskandar J 
Published: June 2021

Abstract
A Performing Arts Centre is a venue that needs optimum acoustic. Many art performances generate high intensity sounds that auditoriums in the building are installed with acoustic systems. Acoustic system is used to reduce the intensity of sounds, for the purpose of giving the audience and performers an ease in listening and producing sounds. Other factors that could affect the ease of audio are the design of the auditorium, the materials that are used to cover the walls and ceiling of the auditorium and the capacity of the auditorium. The research aims to analyze acoustic systems that are optimal to use in an auditorium for performing arts with qualitative methods by using secondary data from case studies and literature related to acoustic systems in performing arts centre by comparing the design of the auditorium alongside the capacity of the hall and the materials that are used to cover the surfaces of the performing arts centre according to acoustic standards referred in Acoustics of Multi-use Performing Arts Centres and Building Physics 2. It is concluded that Benjamin and Marian Schsuter Performing Arts Centre has the optimal acoustic system.
The crops influence on the nutrients content in the soil dynamics in the crop rotation links
Authors: Novikov A A 
Published: June 2021

Abstract
The article discusses the issues of the crop rotations productivity increasing due to the selection of high-ranking agricultural crops and the green manure crops use as independent and stubble crops. The input into the soil of nitrogen, phosphorus and potassium biologically related substances with organic matter of crop residues in different links of the crop rotation were analyzed. It is shown that the largest mass of organic matter enters the soil after winter wheat (12.4 … 12.6 t / ha). In Sarepta mustard cultivated for green manure, the total mass of organic matter entering the soil is up to 11.6 t/ha in stubble crops after winter wheat, and up to 12.6 t/ha in spring crops. The increased application of organic matter to the soil in the amount of 24.1 t/ha was ensured by green manure - Sarepta mustard, cultivated in the intermediate crops of the first and second fields of the crop rotation third link. The cultivation of Sarepta mustard as a siderate in the crop rotation led to the increase in the content of the main elements of plant nutrition in the soil.

Substantiation of the composition of concepts for fuzzy cognitive modeling of food security level in the context of import substitution
Authors: Rogachev A 
Published: June 2021

Abstract
In the national security system of the Russian Federation, food security (FS) is also one of the important tasks, since without a reliable food supply, it is impossible to avoid dependence on other States. Decree of the President of the Russian Federation No. 20 of January 21, 2020 “On the Approval of the Food Security Doctrine of the Russian Federation” approved a new FS Doctrine. The doctrine considers the FS as a multi-component system that includes, as components, the availability of food, its economic, social and physical availability, stability over a long period of time, as well as food issues. To provide cognitive modeling, we can represent the FS support system as a weighted directed graph, whose points correspond to the elements of the set, and whose arcs correspond to the non-zero elements of the W relation. The ratio W can be represented as a matrix of dimension n*n, where n is the number of factors, which can be considered as the adjacency matrix of the graph. The dynamics of the evolution of the simulated socio-economic system and the forecast of its development were obtained by summing increments. The components of the vector of predicted increments of the FCM calculated using the adjacency matrix are calculated at consecutive points in time. It is shown that the following concepts should be taken as key concepts in cognitive modeling of the level of FS: production, consumption, stocks and imports of food, as well as a number of additional ones that characterize the ecological and economic infrastructure for ensuring PB. Modeling has shown that the fluctuating nature of changes in the indicators of all concepts during the transition period forms 3 groups: increasing (FS level, Production, Crop production), stagnating (Consumption) and falling indicators (Import, Irrigation reclamation, Economy, Ecology). The identified trends in the evolution of the main concepts of the level of food security in the context of import substitution should be taken into account when developing programs to ensure FS by subjects of various levels.
Management of the technological process of irrigation of garden plants
Authors: Dubenok N N , Mayer A V 
Published: June 2021

Abstract
Irrigated agriculture has played a very important role in the history of mankind. In many respects, the irrigation technique was highly dependent on local natural conditions, and its development was the process of adapting local plant and water resources to the needs of farmers. The use of land reclamation in modern conditions must be environmentally and energetically justified. Comparing various irrigation technologies for the cultivation of garden plantings, we proposed the introduction of the agrotechnical technique “slitting” into the irrigation technology of garden plantings. Reclamation reception of soil crevice is carried out with a trailed modified unit of the “Slot cutter 2-140” brand, for cutting narrow slots of 3…4 mm, with a chisel located at the end of the cutting body of the slot, for cutting focal reservoirs, followed by accumulation of irrigation water. The research presents a method of cutting slits directed parallel and perpendicular to the aisles of garden plantings. After cutting the cracks, the soil is formed inside the soil - a natural water-intercepting and transporting network of focal reservoirs stretched along and across the entire perimeter of the garden irrigation module. The proposed cutting unit is mounted on a reinforced slot cutter frame on both sides. The distance between the two cutting tools is exactly 2 meters. Such a distance between the working bodies of the slot is dictated by the scheme for planting garden plantings. Irrigation of the garden is carried out by a surface method, i.e. flooding, an irrigation rate calculated for the complete saturation of the soil of the entire area of the garden plot with the lowest moisture capacity up to 100% of the lowest moisture capacity of the calculated meter layer. The proposed technology for irrigation of garden plantations with the obligatory cutting of over narrow slots with focal reservoirs will allow saving water and energy resources spent on the irrigation rate when growing garden plantings.
Intensification of the wastewater treatment process with electrolytic gases

Published: June 2021

Abstract
High regulatory requirements for the quality of treated water discharged into watercourses and wear and tear of local treatment facilities dictate the need to develop new technological solutions in the field of water treatment systems. In this regard, technologies that implement methods of electrophysical or electrochemical impact on polluting components in the processed liquid have found wide application in the treatment of waste and substandard waters. In this case, on the one hand, in order to increase the efficiency of collecting pollutants, it is necessary to strive to increase the number and decrease the size of electrolytic gas bubbles providing this collection, and on the other hand, it is necessary to optimize the operating modes of the electrode system and the material execution of the electrodes themselves, since the time of their operation depends on this. To solve this compromise problem, the design of an electroflotator has been developed, in which an electrode system is installed in the lower part of the tank, consisting of vertical anodes and cathodes. Each pair of them has the shape of cylinders and is fixed on the side surfaces of the dielectric ring separating them. The height of the ring from above and from below is made greater than the height of the anode and cathode by an amount equal to the annular gap between the adjacent anode and cathode. This design of the spacer ring prevents current leakage from the cathode to the anode and, accordingly, the dissolution of the anode ends. If the height of the ring above and below is executed by an amount less than the annular gap, there is a twofold increase in the density of the anode current at the ends of the anode and cathode, intensifying the dissolution of the anodes and the ingress of dissolution products into the solution and onto the walls of the electrodes, increasing their electrical resistance and reducing the performance of treatment facilities by liquid to be cleaned.
Sampling forests with terrestrial laser scanning

Published: June 2021

Abstract

Background and Aims
Terrestrial laser scanners (TLSs) have successfully captured various properties of individual trees and have potential to further increase the quality and efficiency of forest surveys. However, TLSs are limited to line of sight observations, and forests are complex structural environments that can occlude TLS beams and thereby cause incomplete TLS samples. We evaluate the prevalence and sources of occlusion that limit line of sight to forest stems for TLS scans, assess the impacts of TLS sample incompleteness, and evaluate sampling strategies and data analysis techniques aimed at improving sample quality and representativeness.

Methods
We use a large number of TLS scans (761), taken across a 255 650-m2 area of forest with detailed field survey data: the Harvard Forest Global Earth Observatory (ForestGEO) (MA, USA). Sets of TLS returns are matched to stem positions in the field surveys to derive TLS-observed stem sets, which are compared with two additional stem sets derived solely from the field survey data: a set of stems within a fixed range from the TLS and a set of stems based on 2-D modelling of line of sight. Stem counts and densities are compared between the stem sets, and four alternative derivations of area to correct stem densities for the effects of occlusion are evaluated. Representation of diameter at breast height and species, drawn from the field survey data, are also compared between the stem sets.

Key Results
Occlusion from non-stem sources was the major influence on TLS line of sight. Transect and point TLS samples demonstrated better representativeness of some stem properties than did plots. Deriving sampled area from TLS scans improved estimates of stem density.

Conclusions
TLS sampling efforts should consider alternative sampling strategies and move towards in-progress assessment of sample quality and dynamic adaptation of sampling.
DeepIPs: comprehensive assessment and computational identification of phosphorylation sites of SARS-CoV-2 infection using a deep learning-based approach
Authors: Lv Hao , Dao Fu-Ying , Zulfiqar Hasan , Lin Hao 
Published: June 2021

Abstract
The rapid spread of SARS-CoV-2 infection around the globe has caused a massive health and socioeconomic crisis. Identification of phosphorylation sites is an important step for understanding the molecular mechanisms of SARS-CoV-2 infection and the changes within the host cells pathways. In this study, we present DeepIPs, a first specific deep-learning architecture to identify phosphorylation sites in host cells infected with SARS-CoV-2. DeepIPs consists of the most popular word embedding method and convolutional neural network-long short-term memory network architecture to make the final prediction. The independent test demonstrates that DeepIPs improves the prediction performance compared with other existing tools for general phosphorylation sites prediction. Based on the proposed model, a web-server called DeepIPs was established and is freely accessible at http://lin-group.cn/server/DeepIPs. The source code of DeepIPs is freely available at the repository https://github.com/linDing-group/DeepIPs.

Published: June 2021

Abstract
Pseudouridine is a ubiquitous RNA modification type present in eukaryotes and prokaryotes, which plays a vital role in various biological processes. Almost all kinds of RNAs are subject to this modification. However, it remains a great challenge to identify pseudouridine sites via experimental approaches, requiring expensive and time-consuming experimental research. Therefore, computational approaches that can be used to perform accurate in silico identification of pseudouridine sites from the large amount of RNA sequence data are highly desirable and can aid in the functional elucidation of this critical modification. Here, we propose a new computational approach, termed Porpoise, to accurately identify pseudouridine sites from RNA sequence data. Porpoise builds upon a comprehensive evaluation of 18 frequently used feature encoding schemes based on the selection of four types of features, including binary features, pseudo k-tuple composition, nucleotide chemical property and position-specific trinucleotide propensity based on single-strand (PSTNPss). The selected features are fed into the stacked ensemble learning framework to enable the construction of an effective stacked model. Both cross-validation tests on the benchmark dataset and independent tests show that Porpoise achieves superior predictive performance than several state-of-the-art approaches. The application of model interpretation tools demonstrates the importance of PSTNPs for the performance of the trained models. This new method is anticipated to facilitate community-wide efforts to identify putative pseudouridine sites and formulate novel testable biological hypothesis.

Abstract

Background
Neutropenia is commonly encountered in cancer patients. Recombinant human granulocyte colony-stimulating factor (G-CSF, filgrastim), a cytokine that initiates proliferation and differentiation of mature granulocytes, is widely given to oncology patients to counteract neutropenia, reducing susceptibility to infection. However, the clinical impact of neutropenia and G-CSF use in cancer patients with coronavirus disease 2019 (COVID-19) remains unknown.

Methods
An observational cohort of 379 actively treated cancer patients with COVID-19 was assembled to investigate links between concurrent neutropenia and G-CSF administration on COVID-19-associated respiratory failure and death. These factors were encoded as time-dependent predictors in an extended Cox model, controlling for age and underlying cancer diagnosis. To determine whether the degree of granulocyte response to G-CSF affected outcomes, the degree of response to G-CSF, based on rise in absolute neutrophil count (ANC) 24 hours after growth factor administration, was also incorporated into a similar Cox model.

Results
In the setting of active COVID-19 infection, outpatient receipt of G-CSF led to an increased number of hospitalizations (hazard ratio [HR]: 3.54, 95% confidence interval [CI]: 1.25–10.0, P value: .017). Furthermore, among inpatients, G-CSF administration was associated with increased need for high levels of oxygen supplementation and death (HR: 3.56, 95% CI: 1.19–10.2, P value: .024). This effect was predominantly seen in patients that exhibited a high response to G-CSF based on their ANC increase post-G-CSF administration (HR: 7.78, 95% CI: 2.05–27.9, P value: .004).

Conclusions
The potential risks versus benefits of G-CSF administration should be considered in neutropenic cancer patients with COVID-19, because G-CSF administration may lead to worsening clinical and respiratory status.
Neonicotinoid Pesticides Cause Mass Fatalities of Native Bumble Bees: A Case Study From Wilsonville, Oregon, United States
Authors: Hatfield Richard G , Strange James P , Koch Jonathan B , Jepsen Sarina , Stapleton Isaak 
Published: June 2021

AbstractIn June of 2013 an application of dinotefuran on an ornamental planting of European linden trees (Tilia cordata Mill. [Malvales: Malvalceae]) in a shopping mall parking lot in Wilsonville, Oregon provoked the largest documented pesticide kill of bumble bees in North America. Based on geographic information systems and population genetic analysis, we estimate that between 45,830 and 107,470 bumble bees originating from between 289 and 596 colonies were killed during this event. Dinotefuran is a neonicotinoid that is highly effective in exterminating and/or harming target pest insects and non-target beneficial insects. Analysis to detect the concentration of pesticides in flowers that received foliar application revealed that the minimum reported dinotefuran concentration of a sampled T. cordata flower was 7.4 ppm, or in excess of 737% above the LC50 of the beneficial pollinator, the honey bee (Apis mellifera Linnaeus, 1758 [Hymenoptera: Apidae]). Furthermore, sampled Vosnesensky bumble bees (Bombus vosnesenskii Radoskowski, 1862 [Hymenoptera: Apidae]) were found to have an average dinotefuran concentration of 0.92 ppm at the time of death, which exceeds the maximum LC50 of A. mellifera (0.884 ppm). Our study underscores the lethal impact of the neonicotinoid pesticide dinotefuran on pollinating insect populations in a suburban environment. To our knowledge, the documentation and impact of pesticide kills on wild populations of beneficial insects has not been widely reported in the scientific literature. It is likely that the vast majority of mass pesticide kills of beneficial insects across other environments go unnoticed and unreported.
Changing views of English through study abroad as teacher training
Authors: Suzuki Ayako 
Published: June 2021

Abstract
As English has become an essential international language, some universities in countries where students learn the language mainly in the classroom have started to send teachers overseas as part of English teacher training. Study abroad (SA) is perceived as one effective way to improve teachers’ intercultural communication ability in English because it is believed that studying with culturally diverse others using English as a lingua franca (ELF) could help them to develop English proficiency and intercultural understanding. This study focuses on one group of Japanese pre-service English teachers who undertook SA as teacher training and looks into whether this contributed to the development of views of English for intercultural communication. The study found that their changes in ideas about English were brought about by their intricate understanding of ELF communication. This result addresses the need for teachers to learn sociolinguistic aspects of intercultural communication before undertaking SA.
Microalgae as feed ingredients: recent developments on their role in immunomodulation and gut microbiota of aquaculture species

Published: June 2021

ABSTRACTMicroalgae are rapidly evolving alternative ingredients in food and feed. Desirable nutritional and functional qualities make them high potential sources of feed ingredients. Certain microalgae species are known to accumulate large amounts of protein, containing all essential amino acids while some species contain essential fatty acids and bioactive compounds hence offering several possible health benefits. However, successful inclusion of microalgae-based products in feed requires a clear understanding of physiological responses and microbiota of animals receiving microalgae diets. In this review, key microalgae-based feed ingredients and their effect on gut microbiome and immunomodulatory responses of microalgae fed animals, with a focus on aquatic species will be discussed.
Two-part tariff contract design for a supplier base: a unifying methodology
Authors: Alcívar Espín Roberto Andrés , Chou Yon-Chun , Huang Ching-Chi 
Published: June 2021

Abstract
Conventional contract designs largely aim to coordinate decisions in dyadic relationships. In the new era of network environments and near-zero variable costs for many goods and services, a different approach to contract design is required for two reasons. First, offering a set of contracts to multiple contractors of different objectives, sizes, and business practices will allow each to choose the most suitable contract. Second, given that most previous studies have not considered quasi-fixed costs, it is helpful to understand two-part tariff contracts and their variants for a supplier base, new variants based on quasi-fixed costs, and related decision sequences between the parties in a supply chain. We propose a unifying methodology to set the contract parameters so that the different variants will have comparable performance outcomes. The results and the insights gained suggest that the proposed methodology should improve a retailer’s management of its supplier base and also benefit all parties throughout the supply chain.
