Low Dose CT Denoising by ResNet With Fused Attention Modules and Integrated Loss Functions
Authors: Alirezaie Javad
Published: October 2022

X-ray computed tomography (CT) is a non-invasive medical diagnostic tool that has raised public concerns due to the associated health risks of radiation dose to patients. Reducing the radiation dose leads to noise artifacts, making the low-dose CT images unreliable for

diagnosis. Hence, low-dose CT (LDCT) image reconstruction techniques have offered a new research area. In this study, a deep neural network is proposed, specifically a residual network (ResNet) using dilated convolution, batch normalization, and rectified linear unit

(ReLU) layers with fused spatial- and channel-attention modules to enhance the quality of LDCT images. The network is optimized using the integration of per-pixel loss, perceptual loss via VGG16-net, and dissimilarity index loss. Through an ablation experiment, these functions show that they could effectively prevent edge oversmoothing, improve image texture, and preserve the structural details. Finally, comparative experiments showed that the qualitative and quantitative results of the proposed network outperform state-of-the-art

denoising models such as block-matching 3D filtering (BM3D), Markovian-based patch generative adversarial network (patch-GAN), and dilated residual network with edge detection (DRL-E-MP).

Authors: Bahuguna Rahul , Chamoli Sunil , Barthwal Yogesh , Rana Sumit , Gupta Ashutosh , Singh Bisht Vijay
Published: October 2022

Due to the minimal transfer of heat from absorber plate to moving air in the duct, solar air heaters have low performance. One of the procedures to augment the heat transfer by substantial amount is by utilizing artificial roughness, by which the performance can be improved considerably. In this study, an economic investigation of solar air heater embedded with artificial roughness is accomplished numerically employing v-shaped roughness, with the objective of optimising life cycle solar savings. The non-dimensional parameters of roughness, namely, angle of attack (α), roughness pitch (p/e) and roughness height (e/Dh) are examined by varying temperature rise over the solar air heater (∆T) and solar radiations (I) for different economic parameters values i.e., cost of collector, cost of roughness elements, and cost of conventional fuel.
Servitization Review: Focused on Domestic Researches
Authors:   The Korean Production And Operations Management Society, Ahn Chulok
Published: October 2022

In the last three decades, servitization has been researched in the pursuit of combining products and services, that is, integrating manufacturing and service industries. Globally, studies to establish servitization theories have been conducted since the pioneering work of Vandermerwe and Rada (1988). However, in Korea, full-scale research was not conducted until the late 2000s. Therefore, in this study, global research trends of servitization are briefly introduced, and the definition of servitization in Korea is discussed. The study also discusses the direction research has taken since the late 2000s to the 2020s. Over 70 studies, mainly published in KCI journals, were organized and analyzed. This study helps in the understanding of servitization and explores multiple application cases and methods in various industries. Also, this study will lead to discussions about different opinions on servitization and productservice system (PSS). Finally, this study suggests avenues for future research currently lacking in the study of servitization.
The Effects of Dynamic Capability and Ambidextrous Capability on the Performance Creation Process of Sustainable Supply Chain Management: The Buying Companies’ Perspective
Authors:   The Korean Production And Operations Management Society, Park Eun Shil , Choi Do Young
Published: October 2022

This study focuses on the role of dynamic and ambivalent competence among factors affecting sustainable supply chain activity and its performance creation process. Sustainable supply chain management should pursue economic, environmental, and social activities simultaneously, and decision making such as coordination and resource allocation among these activities is inevitably important. Therefore, this study examines the role of dynamic and ambivalence capacities of adjustment and resource allocation among various factors affecting sustainable supply chain management, and conducts an empirical analysis focusing on the process of performance creation between purchasers and customers. Accordingly, a survey was conducted on those in charge of managing supply chain management in a company, and 296 valid questionnaires were analyzed to verify the research hypothesis. The analysis revealed that both dynamic and ambivalent competences have a positive effect on the economic, environmental, and social activities of sustainable supply chain management. Conversely, economic and social activities have a positive effect on both supplier and purchasing company performance, whereas environmental activities do not have any effect. Furthermore, the result of suppliers through sustainable supply chain activity was confirmed to have a positive effect on the performance of the purchaser. The findings are meaningful in that they present theoretical grounds for the importance of coordination and resource allocation among the three main aspects that constitute sustainable supply chain activities and empirically suggest that dynamic and ambivalent capabilities can serve as a significant preceding factor in creating results.

Published: October 2022

Nutrient stimulation is considered effective for improving biogenic coalbed methane production potential. However, our knowledge of the microbial assembly process for profuse and rare microbial communities in coals under nutrient stimulation is still limited. This study collected 16S rRNA gene data from 59 microbial communities in coals for a meta-analysis. Among these communities, 116 genera were identified as profuse taxa, and the remaining 1,637 genera were identified as rare taxa. Nutrient stimulation increased the Chao1 richness of profuse and rare genera and changed the compositions of profuse and rare genera based on nonmetric multidimensional scaling with Bray-Curtis dissimilarities. In addition, many profuse and rare genera belonging to Proteobacteria and Acidobacteria were reduced, whereas those belonging to Euryarchaeota and Firmicutes were increased under nutrient stimulation. Concomitantly, the microbial co-occurrence relationship network was also altered by nutrient addition, and many rare genera mainly belonging to Firmicutes, Bacteroides, and Euryarchaeota also comprised the key microorganisms. In addition, the compositions of most of the profuse and rare genera in communities were driven by stochastic processes, and nutrient stimulation increased the relative contribution of dispersal limitation for both profuse and rare microbial community assemblages and that of variable selection for rare microbial community assemblages. In summary, this study strengthened our knowledge regarding the mechanistic responses of coal microbial diversity and community composition to nutrient stimulation, which are of great importance for understanding the microbial ecology of coals and the sustainability of methane production stimulated by nutrients.

Published: October 2022

Whole-genome sequencing and genome mining are recently considered an efficient approach to shine more light on the underlying secondary metabolites of Streptomyces. The present study unearths the biosynthetic potential of endophytic SX6 as a promising source of biologically active substances and plant-derived compounds for the first time. Out of 38 isolates associated with Aegiceras corniculatum (L.) Blanco, Streptomyces parvulus SX6 was highly active against Pseudomonas aeruginosa ATCC® 9027™ and methicillin-resistant Staphylococcus epidermidis (MRSE) ATCC® 35984™. Additionally, S. parvulus SX6 culture extract showed strong cytotoxicity against Hep3B, MCF-7, and A549 cell lines at a concentration of 30 μg/ml, but not in non-cancerous HEK-293 cells. The genome contained 7.69 Mb in size with an average G + C content of 72.8% and consisted of 6,779 protein-coding genes. AntiSMASH analysis resulted in the identification of 29 biosynthetic gene clusters (BGCs) for secondary metabolites. Among them, 4 BGCs showed low similarity (28–67% of genes show similarity) to actinomycin, streptovaricin, and polyoxypeptin gene clusters, possibly attributed to antibacterial and anticancer activities observed. In addition, the complete biosynthetic pathways of plant-derived compounds, including daidzein and genistein were identified using genome mining and HPLC-DAD-MS analysis. These findings portray an exciting avenue for future characterization of promising secondary metabolites from mangrove endophytic S. parvulus.

Published: October 2022

In the present study, a comparative genome analysis of the novel alkaliphilic actinobacterial Nesterenkonia haasae with other members of the genus Nesterenkonia was performed. The genome size of Nesterenkonia members ranged from 2,188,008 to 3,676,111 bp. N. haasae and Nesterenkonia members of the present study encode the essential glycolysis and pentose phosphate pathway genes. In addition, some Nesterenkonia members encode the crucial genes for Entner-Doudoroff pathways. Some Nesterenkonia members possess the genes responsible for sulfate/thiosulfate transport system permease protein/ ATP-binding protein and conversion of sulfate to sulfite. Nesterenkonia members also encode the genes for assimilatory nitrate reduction, nitrite reductase, and the urea cycle. All Nesterenkonia members have the genes to overcome environmental stress and produce secondary metabolites. The present study helps to understand N. haasae and Nesterenkonia members’ environmental adaptation and niches specificity based on their specific metabolic properties. Further, based on genome analysis, we propose reclassifying Nesterenkonia jeotgali as a later heterotypic synonym of Nesterenkonia sandarakina.

Authors: Tsaruk L.L
Published: October 2022

Probiotic feed additives in pig diets can be an alternative and highly effective way to solve a number of problems in industrial pig production. In the course of the studies, it was revealed that different conditions for the use of a probiotic preparation for suckling piglets cause changes in the productivity of young animals in their further cultivation. The probiotic preparation "Probiol ENZIM Feeds" was studied in two ways of feeding suckling piglets: soluble (125 g/ m3) and loose (250 g/t) in summer and winter periods. It was found that in the summer period the best growth rates were in animals treated with the probiotic preparation "Probiol ENZIM Feeds" in electrolyte-soluble form, and in winter - with feed in the amount of 0,25 kg/t. The best fattening properties during the growing period were found in pigs that received a probiotic preparation in loose form during the suckling period. In particular, when using a new feeding factor in a soluble form in the summer period, it is possible to achieve an increase in the live weight of piglets at weaning by 6,8%, gross gain - by 7,4%, average daily - by 10,6%. In winter, the best results were obtained when using a probiotic in loose form, where an increase in live weight occurred by 11,1%, gross growth - by 12,6% and average daily growth - by 17,7%. During the growing period, young pigs of the first experimental group had 6,8 g greater average daily gains; in the winter period of our research, pigs that received a probiotic preparation with feed during the suckling period reached slaughter conditions 3 days faster. The carcasses of pigs that received a probiotic preparation with feed during the lactation period were 2,07% heavier, the slaughter yield was 1,3% higher, and the fat thickness was 3,37 mm more. When using the loose method of feeding a new feeding factor for suckling piglets, it is possible to increase the yield of fat from the carcass and increase the meatiness of the carcass by 2,41%. Calculations have proved that when using Probiol ENZIM Feeds with feeding for suckling piglets, it is possible to achieve an increase in the profitability of pork production by 2,86 hryvnia / hryvnia. expenses.
Key words: probiotic preparation, feeding, young pigs, large white breed, productivity, economic efficiency.

A New Strategy to Enhance the Security of GPS Location by PGP Algorithm in Smart Containers
Authors: Saleem jan Mehrunnisa , Ahmed Salman , Safdar Nawaz Khan Marwat
Published: October 2022

Dynamic navigation devices like Global Positioning Systems (GPSs) are deployed for various purposes in different areas and these devices are usually the central point of interest of various groups like hackers to exploit the data sent and received by GPS systems. The GPS data is usually manipulated using spoofing attacks. This paper proposes a robust solution to the spoofing attacks carried out to manipulate, control and modify the location sharing of smart containers. The primary focus of this paper is securing the GPS information shared by the smart containers. The location shared by the smart containers is secured by encrypting it with Pretty Good Privacy (PGP) algorithm to avoid spoofing attacks in particular. The encrypted GPS location is sent across any communication channel. The receiver side will decrypt the encrypted GPS location at the receiving end. Hence, using this method of PGP encryption will ensure the safe and secure sharing of GPS location by the smart containers. As a result, GPS security has been improved by 80%.
Constacyclic and Negacyclic Codes over $\mathbb{F}_{2}+u\mathbb{F}_{2}+v\mathbb{F}_{2}$ and their Equivalents over $\mathbb{F}_{2}$
Authors: ÖZKAN Mustafa , YENİCE Berk , GÜROĞLU Ayşe Tuğba

In this work, we consider the finite ring $\mathbb{F}_{2}+u\mathbb{F}_{2}+v\mathbb{F}_{2}$, $u^{2}=1, v^{2}=0$, $u\cdot v=v\cdot u=0$ which is not Frobenius and chain ring. We studied constacyclic and negacyclic codes in $\mathbb{F}_{2}+u\mathbb{F}_{2}+v\mathbb{F}_{2}$ with odd length. These codes are compared with codes that had priorly been obtained on the finite field $\mathbb{F}_{2}$. Moreover, we indicate that the Gray image of a constacyclic and negacyclic code over $\mathbb{F}_{2}+u\mathbb{F}_{2}+v\mathbb{F}_{2}$ with odd length $n$ is a quasicyclic code of index $4$ with length $4n$ in $\mathbb{F}_{2}$. In particular, the Gray images are applied to two different rings $S_{1}=\mathbb{F}_{2}+v\mathbb{F}_{2}$, $v^{2}=0$ and $S_{2}=\mathbb{F}_{2}+u\mathbb{F}_{2}$, $u^{2}=1$ and negacyclic and constacyclic images of these rings are also discussed.

Published: October 2022

La transición hacia una economía circular requiere de metodologías e indicadores que permitan realizar una comprehensión exhaustiva del uso de recursos en todos los sistemas. Este trabajo presenta la evaluación de los flujos materiales de una red de simbiosis industrial compuesta por cinco empresas en Mendoza, Argentina. Se realizó un Análisis de Flujo de Materiales para el año 2021 que consistió en estudiar los flujos de entrada y salida de los procesos que incluyen residuos sólidos urbanos, residuos plásticos, pellets de plástico reciclado y recursos para la elaboración de plástico virgen. La red de simbiosis industrial logró reducir en un 97% la disposición final de residuos en vertedero y recuperar 602 toneladas anuales de materiales. Con el objetivo de analizar la circularidad de este sistema, se utilizó el factor de cascada como indicador, el cual incluye información sobre flujos de materia prima virgen, residuos posconsumo y residuos industriales; además se tuvo en cuenta la eficiencia del reciclaje mediante una modificación del indicador original. Cuando se analizó el indicador para el sistema global resultó en 1,03, mientras que cuando se desagregó el resultado para el sector de empresas que reciclan residuos plásticos se obtuvo un valor de 15,07. El factor de cascada permite un análisis de los distintos flujos materiales; sin embargo, existen aspectos que pueden mejorarse para una correcta evaluación de los beneficios de la simbiosis industrial, como el reemplazo de materia prima virgen y los flujos residuales que terminan en vertedero.

PROPOSAL FOR A BALANCED AND STABLE INTERNATIONAL MONETARY SYSTEM
Authors: Rahman Abdurrahman Arum
Published: October 2022

This paper proposes a new model of the international monetary system that could potentially make the system balanced and stable. We call it an “organic system”. We utilize a 3-dimensional simulation of trade and investment involving 5 countries, 20 products, and a 12-month or 5x20x12 model to test the workability of the system. The results show that this model could provide international liquidity to all (member) countries in the world sustainably, eliminate global imbalances to the roots, and make the IMS naturally stable. The simulation also shows that the current accounts, balance sheets, and FX reserves of all member countries tend to be self-sufficient. We implant a digital-and-decentralized system in the very core of the system, which works semi-automatically. This system is flexible; it can start from anywhere in the world and any country may join.
The Holy Grail of Mathematics
Authors: Vega Frank
Published: October 2022

A trustworthy proof for the Riemann hypothesis has been considered as the Holy Grail of Mathematics by several authors. The Riemann hypothesis is a conjecture that the Riemann zeta function has its zeros only at the negative even integers and complex numbers with real part $\frac{1}{2}$. Let $Q$ be the set of prime numbers $q_{n}$ satisfying the inequality $\prod_{q \leq q_{n}} \frac{q}{q-1}>e^{\gamma} \cdot\log\theta(q_{n})$ with the product extending over all prime numbers $q$ that are less than or equal to $q_{n}$, where $\gamma\approx 0.57721$ is the Euler-Mascheroni constant, $\theta(x)$ is the Chebyshev function and $\log$ is the natural logarithm. If the Riemann hypothesis is false, then there are infinitely many prime numbers $q_{n}$ outside and inside of $Q$. In this note, we obtain a contradiction when we assume that there are infinitely many prime numbers $q_{n}$ outside of $Q$. By reductio ad absurdum, we prove that the Riemann hypothesis is true.

Published: October 2022

According to the results of a 2022 survey conducted by the Association of Indonesian Internet Service Providers (APJII), internet users in Indonesia continued to increase from 175 million to 220 million users of the total population of Indonesia. The increase was driven by the need for communication during the Covid-19 pandemic in the last two years. Most internet users are on the island of Java, followed by the islands of Sumatra, Kalimantan, Sulawesi, Bali-Nusa, and Maluku-Papua. PT. Tentrem Sejahtera is one of the Inter-City In-Province bus companies based on the island of Java, precisely in East Java. The ordering and payment process is still done manually or offline. Consumers who want to buy tickets must come directly to the terminal, to an authorized agent who has been appointed or do it directly when boarding the bus and make transactions in cash. Where when making manual or cash payments sometimes you have to wait a few minutes to issue money and wait for the ticket given by the conductor, while the level of security in payments is very less, so it is less efficient in this sophisticated era. In addition, there are still unscrupulous brokers at several bus departures who sell tickets that do not match the specified price. This study used the e-wallet electronic payment model method, with a mobile payment system for QRIS-based bus fares. With the National Mercant ID (NMID) listed on the QRIS display, a receipt will be issued on the Thermal Print for proof of payment.

Published: October 2022

The paper presents the results of studies on the study of different doses of potash fertilizers in combination with phosphate fertilizers, both with a separate application and in combination with the biological product Humimax, when cultivating narrow-leaved lupine for green mass, in a field experiment on soddy-podzolic sandy soil (with a pollution density of 20 and more than Ku/km2). The effectiveness of the influence of doses of potash fertilizers and the biopreparation Humimax on the yield, accumulation of 137Cs and the nutritional value of the green mass of the narrow-leaved lupine was studied. It has been established that the use of the Humimax biopreparation provides an increase in the yield of the green mass of lupin up to 69%. The use of the biological product on all backgrounds of fertilization provides an increase in the content of crude protein in the green mass of lupine. Consistently increasing doses of potassium in combination with P45, both when used alone and in combination with a biological product, reduced the specific activity of 137Cs by more than 2.5 times. To reduce the accumulation of 137Cs in the green mass of lupine below the permissible level, the doses of mineral fertilizers should not be lower thanP45K150.

Tests of this technology were carried out in the mountainous area of the Republic of North Ossetia – Alania (Dargava basin, the stronghold of SKNIIGPSH) at an altitude of 1540 m above sea level of the southeastern exposure with a slope steepness of up to 15º. It was found that the content of feed units in compressed hay increased by 32.1%; dry matter by 29.6%; crude protein by 17.3%; fat by 7.4%; fiber by 14.2%; sugar by 17.6%; metabolic energy by 8.0%. With an increase in the nutritional value of the feed mass, the digestibility of harvested feed increases by 18.5%, which positively affects the physiological condition of animals in the winter stall period, increasing milk yield by 11.7%.
Feed quality when using new varieties of legume grass species in improved legume-cereals grass stands in cycles and years of use
Authors: Kutuzova Anel , Provornaya Elena , Sedova Ekaterina , Tsybenko Nadezhda
Published: October 2022

The article presents the results of studies of the quality of pasture feed in the dynamics on the cycles of use of legume-cereals grass stands, including new zoned varieties (creeping and meadow clover, alfalfa variable). Evaluation of the crude protein content of the feed revealed isolated cases (10–15% of the database) of a decrease in its concentration below the third class. Therefore, to guarantee the preservation of feed quality at the level of 1–3 classes, it is proposed to create 2–3 legume-cereals grass stands in the structure of the late link in different ratios of their area depending on the location and soil conditions.

Published: October 2022

In the Federal Scientific Center "VIK im. V. R. Williams” conducted research on the evaluation of new varieties of spring and winter colza Zarya and Nadezhda when growing broiler chickens of the Cobb 500 cross. The control group received compound feed without rapeseed seeds. The first and second experimental groups included 7.5% by weight of mixed fodder native rapeseed seeds of Zarya and Nadezhda varieties, which were used to replace part of soybean meal and sunflower oil. The content of nutrients in mixed feed complied with the regulatory requirements. The oil was balanced in composition: a large amount of monounsaturated, low-saturated fatty acids, a moderate amount of polyunsaturated fatty acids. It has been established that compound feeds with rapeseed seeds do not negatively affect the live weight gain of experimental broiler chickens. On the 39th day, the live weight of chickens in the control, in the first and second experimental groups was 2.250, 2.245 and 2.256 g, respectively. The significance of the difference in this indicator with the control group has not been established (P > 0.05). In the study of blood serum in chickens of the first experimental group, an increased level of bilirubin and the enzyme glutamyltransferase was revealed, which indicates stagnation of bile in the bile ducts (P > 0.01). The efficiency of growing poultry using rapeseed seeds was higher than in the control, which is associated with a decrease in feed costs for obtaining meat products and a lower cost of experimental feed.

Article is devoted the basic sources of errors at quality definition of bulky forages – by sampling, by amendments at definition of the dry matter content, to infringement of a technique of crude fiber determination. It is impossible to eliminate the errors admitted at the initial stages of the analysis using any subsequent operations and results of a forage quality estimation can appear, thus, absolutely unsuitable for successful application. In this connection questions of perfection of standardization of forage quality by the severe control over observance of a technique of forages sampling, uses of corresponding techniques of dry matter definition depending on a kind of a forage and the strict execution of all stages of a crude fiber definition are discussed. The brief information on addition of new standards with norms of NDF and ADF content for quality categories of bulky forages is given.
