Authors: Pai Albert C. , Panos Anthony L. , Ricci Marco
Published: July 2022

Systemic right ventricular failure after physiologic repair for
dextro-transposition of the great arteries can be managed with durable
mechanical circulatory support; however, the right ventricular
morphology, such as intervening papillary muscles, presents challenges
to inflow cannula positioning. Papillary muscle repositioning is an
innovative technique to circumvent the obstructive anatomy.

Authors: Wang Wei , Li Lina , Gu Hongjun , Chen Yanqing , Zhen Yumei , Dong Zhaorui
Published: July 2022

Objective: To develop a machine learning-based model for predicting the
risk of acute respiratory distress syndrome (ARDS) after cardiac
surgery. Methods: Data were collected from 1011 patients who underwent
cardiac surgery between February 2018 and September 2019. We developed a
predictive model on ARDS by using the random forest algorithm of machine
learning. The discrimination of the model was then shown by the area
under the curve (AUC) of the receiver operating characteristic curve.
Internal validation was performed by using a 5-fold cross-validation
technique, so as to evaluate and optimize the predictive model. Model
visualization was performed to reveal the most influential features
during the model output. Results: Of the 1011 patients included in the
study, 53 (5.24%) suffered ARDS episodes during the first postoperative
week. This random forest distinguished ARDS patients from non-ARDS
patients with an AUC of 0.932 (95% CI=0.896-0.968) in the training set
and 0.864 (95% CI=0.718-0.997) In the final test set. The top 10
variables in the random forest were cardiopulmonary bypass time,
transfusion red blood cell, age, EUROSCORE II Score, albumin,
hemoglobin, operation time, serum creatinine, diabetes, and type of
surgery. Conclusion: Our findings suggest that machine learning
algorithm is highly effective in predicting ARDS in patients undergoing
cardiac surgery. The successful application of the generated random
forest may guide clinical decision making and aid in improving the
long-term prognosis of patients.
Deep Reinforcement Learning based Secure Wireless Communication with Self-powered Intelligent Reflecting Surface
Authors: Kang Joonhyuk , Kim Sanghyuk
Published: July 2022

This paper addresses a multiple-input, single-output (MISO) downlink
secure wireless communication system assisted by an intelligent
reflecting surface (IRS). Instead of employing a conventional IRS model
that requires an external power supply, we consider a self-powered IRS
to achieve extra resource efficiency. Our goal is to design a
beamforming vector at the transmitter side and phase shifters for the
IRS that maximize the secrecy rate while assuring seamless IRS operation
via energy harvesting (EH). Since the considered optimization cannot be
solved analytically, we propose to utilize deep reinforcement learning
(DRL). Numerical results verify that the proposed DRL-based solution
outperforms the conventional relaxed convex optimization approach in
both secrecy and energy harvesting perspectives.

Historically, root diseases have been a production-limiting problem for the strawberry industry worldwide. Even though this disease is of great economic importance, the etiology remains unresolved. However, soilborne fungal root pathogens, particularly Pythium and Rhizoctonia spp. have been implicated as major role players. Presence of nematodes in soil and favourable environmental conditions also play significant role in the disease development. Development of integrated disease management strategies is dependent upon a more complete understanding of the etiology, biology and ecology of the disease complex.

Markers are any trait of an organism that can be identified with confidence and relative ease, and can be followed in a mapping population or they can be defined as heritable entities associated with the economically important trait under the control of polygenes. Molecular markers have diverse applications in fruit crop improvement, particularly in the areas of genetic diversity and varietal identification studies, disease diagnostics, hybrid detection, sex differentiation and marker assisted selection. Molecular markers provide new directions to the efforts of plant breeders particularly in gene localization, taxonomy, phylogenetic analysis and also play an important role to decrease the time required for development of new and excellent cultivars. The most interesting application of molecular markers is marker-assisted selection (MAS). Suitable DNA markers should be polymorphic in the nature and should be expressed in all tissues, organs, at various developmental stages. Compared with traditional breeding programs, molecular markers can increase the efficiency and effectiveness of fruit breeding programs.

Authors: Sutisna Nanang Ali , Permana Fahyudha
Published: July 2022

This paper presents a study on the production capacity of stamping dies for minting coins under different heat treatment processes, particularly austenite temperatures, using a vacuum furnace. In the study, the specimen material was made from Bohler K340 steel. The first heat treatment strategy included heating the specimens to a stable austenite temperature at 1080°C, then holding for 120 minutes and cooling rapidly with gas quenching media with a pressure of 5 bar. Tempered treatment was performed at 500°C. Another strategy was similar to the first one, except the heating temperature at 1060°C and double tempering at 575°C. After the heat treatment process, microstructure observation and hardness testing were carried out. Finally, the production of the die capacity testing on the coining machine was conducted. The results of the specimen surface photographs of the two heat treatment strategies show a significant difference in the microstructure, similarly with the hardness value obtained from single tempering is 61.98 HRC and from double tempering is 57.94 HRC. The production capacity test result indicates that the average capacity of first and second dies are 101,250 coins and 171,150 coins, respectively. It means that the second dies exceed the minimum standard production capacity of dies as determined by the Quality Control department, which is 150,000 coins.

Authors: Zile Mehmet
Published: July 2022

Voltage regulation needs to be optimised to reduce energy losses and improve power quality in renewable solar/wind plants. The Artificial Bee/Ant Hybrid Heuristic Algorithm has been developed in the study, and voltage regulation was optimised using this developed algorithm. A computer program in the C++ programming language was developed to prevent the undesired effects of electrical events occurring during the integration of renewable energy sources and to make the system work more efficiently. The interface of the program was made using the Visual Studio program. It became possible to produce power estimation, power quality estimation and power loss estimation using the intuitive artificial bee/ant hybrid algorithm created on the data set obtained from solar and wind power plants. It was found that there is a ± 4% difference between the values obtained with the developed algorithm and the computer program and the values obtained from the power plants. The developed algorithm and the computer program successfully optimise power quality in solar/wind power stations. The study makes it possible to estimate the amount of energy produced, the amount of energy loss, and the quality of energy in solar/wind power stations.

APPLICATION OF GENERALIZED DERIVATIVE OPERATOR ON BOUGUER ANOMALY FOR DETECTING GEOLOGICAL STRUCTURES
Authors: Zaky Dicky Ahmad , Bilqis Alissa
Published: July 2022

Generalized Derivative Operator (GDO) is one of the first-order derivative filters that could control the derivative’s direction by modifying the value of azimuth () and dip () parameters. This study aims to examine those GDO parameters on synthetic Bouguer anomaly and apply them to field data of the Silver Peak geothermal field to identify the geological structures. We use Python programs to conduct the GDO and other derivative operators such as horizontal gradient (HG), analytic signal amplitude (AS), as well Second Vertical Derivative (SVD) for comparison. The derivative operators are performed in the Fourier domain and spatial domain. The results from synthetic data show that GDO can amplify the response both on local and regional anomalies. Nevertheless, enhanced local and regional anomaly might be shown as the same maximum value of GDO. It appears that GDO disregard the influence of density contrast and depth variation of the anomalous body. Subsequently, anomaly enhancement of Silver Peak area shows that GDO anomaly concurred with geological map. GDO and SVD could amplify the response of geological structures such as intrusive granite, fault lineaments, and lithological contact, as well as the horst-graben structure, as mentioned in previous studies, that might be acting as fluid pathways for the Silver Peak geothermal system.

Published: July 2022

Pewarna adalah salah satu bahan tambahan pangan yang berfungsi untuk meningkatkan kualitas penampilan makanan. Keanekaragaman bahan pewarna pangan merupakan inovasi yang terus berkembang untuk meningkatkan mutu dan daya jual pangan di pasaran. Namun hingga saat ini pewarna makanan di pasaran masih banyak yang menggunakan pewarna tekstil, padahal sudah jelas bahwa pewarna tekstil sangat berbahaya bagi tubuh. Oleh karena itu, dilakukan penelitian ini agar bisa dijadikan alternatif pewarna alami untuk makanan yang berasal dari buah bit sebagai pengganti pewarna buatan. Pada penelitian ini bahan yang digunakan hanya buah bit dan asam sitrat yang selanjutnya dilakukan dua pengujian yaitu uji kadar air dan uji intesitas warna. Pada pengujian intesitas warna dilakukan dengan metode kolorimeter. Hasil pengujian kadar air menunjukkan bahwa konsentrasi asam sitrat dengan hasil humiditas berpengaruh pada serbuk buah bit, maka hasil yang memiliki kadar paling rendah yaitu dengan konsentrasi asam sitrat 0,5% terdapat pada sampel (4).

The paper focuses on the proper names of over-the-counter drugs and nutritional supplements for adult users, with a research sample of 202 names. The aim is to abstract and typologize the motivants of serionyms, to generalize their communicative and pragmatic potential with regard to linguistic form, target group of consumers and functional members. The tool to fulfill the goal is model and pragmatic analysis, which falls within the research field of onomastics and pragmalinguistics. The pragmatic function of serionyms is related both to the preservation of their appellative semantics and to the way they are produced, namely at the level of motivation and invention. The focus on the target group manifests itself by acting on the emotional or rational component of the percipient's personality, exposing gender stereotypes. The communicative and pragmatic potential of the selected proper names is implemented at the systemic level, first of all, in the functional member of the property, which is an abstraction of figurative naming and template-like gender attributes, and which refers both to the composition and characteristics of the product, and to the characteristics of the user. Meanwhile, the variability of the serionyms increases with increasing number of functional members from two-member models to six-member models.

The short bowel syndrome (SBS, or simply short gut) is the most common cause for the chronic intestinal failure (CIF). The purpose of the study was to present the results of treatment of infants at risk for the development of post-resection SBS and the formation of CIF. Research materials and methods: 22 children threatened by the formation of post-resection SBS were treated in the Surgical Department of Newborns and Infants of the National Medical Research Center for Children’s Health (Moscow, Russia) from 2017 to 2021. Results: All patients have undergone the surgical treatment. The scope of the surgical intervention included adhesiolysis with the imposition of an interintestinal anastomosis. Simultaneous imposition of multiple interintestinal anastomoses (more than 4) was performed in 7 patients (32%). As a result, the CIF formation was avoided in 8 patients (36%) by maintaining the total length of the remaining small intestine. The follow-up period ranged from 12 to 46 months. Currently, 2 patients (9%) receive partial parenteral nutrition, and in 17 patients (77%) it was possible to achieve completely autonomous enteral nutrition. A lethal outcome was stated in 3 patients (14%) due to the development of a catheter-associated infection. Conclusion: in the course of this work, the principles of surgical treatment of patients threatened by the development of post-resection SBS and the formation of CIF were developed. Adequate parenteral and enteral nutrition can optimize intestinal adaptation and improve the nutritional status of the pediatric patient.

The chemotherapy-induced nausea and vomiting (CINV) are of the most difficult to tolerate, often distressing, complications from a patient's point of view. Despite the success of modern antiemetic therapy this problem is far from being solved and the real effectiveness of antiemetic prophylaxis in children in Russia has not been studied as yet. The purpose of the study was to evaluate the effectiveness of routine CINV prevention against the highly emetogenic chemo in real clinical practice. Materials and methods of the study: the study included 88 patients aged 5 to 18 years old who received treatment from October, 2020, till June, 2021. The median age of patients was 14 [12.5-16] years old; the boys/girls ratio was 53%/47%. During the observation period the studied patients received 456 cycles of highly emetogenic chemo - Me (Q1-Q3) 5 (3-7). All of the patients included in this single-center prospective cohort study have received a standard three-component prophylaxis regimen that consisted of aprepitant, dexamethasone and a 5HT-3 receptor blocker on days of cytostatic therapy. Nausea and vomiting were assessed using the MASCC Antiemesis Tool (MAT) questionnaire and Baxter Retching Faces (BARF) and Pediatric Nausea Assessment Tool (PeNAT) graphic scales. Results: thanks to the use of the standard antiemetic prophylaxis the total control of CINV was achieved in 312 (68%), 239 (52%) and 198 (43%) cycles in the acute, delayed and general periods, respectively. The factors that were statistically significantly associated with an increase in the incidence of CINV were as follows: multi-day chemo regimens (p=0.016), high doses of cisplatin or carboplatin in the treatment regimen (p<0.001) and anticancer therapy for a solid tumor (p=0.002). The presence of vomiting at the previous stage of cytostatic treatment also statistically significantly increased the incidence of CINV (p<0.001). Conclusion: against the background of standard antiemetic prophylaxis more than a half of all the children receiving highly emetogenic cytostatic therapy continue to suffer from CINV. This requires the development and implementation of a modern, more effective approaches to the CINV prevention. The risk factors for the development of CINV identified in the study could be of help in further studies in order to stratify patients into groups. The fact of a significant increase in the risk of CINV development in patients who experienced these complications during initial therapy indicates the need for the most effective prevention of CINV from the very first cycle of treatment.
