Introduction: At present, the volume of system logs of computer systems integrated into a distributed network infrastructure makes it impossible to manually check them in real time. Typically, the structure of each log record contains the numeric value of the observed attribute and a corresponding flag to mark the record as normal or abnormal. The support vector data description algorithm demonstrates high classification accuracy even with small volumes of the training sample. A feature of the algorithm is the work with a multi-attribute dataset, where each observation contains a common classifying marking. Consequently, the problem arises of reducing the set of markings of the attributes of the initial data to one marking of the entire observation. Purpose: to investigate the accuracy of the binary classification of experimental data of the Support Vector Data Description algorithm with a small volume of the training sample, provided that the data are labeled for each attribute separately. Methods: a method is proposed for solving the problem of reducing the set of markings of the attributes of the initial data to one single marking of the entire observation by means of two approaches: "normal observation" and voting by the majority principle. Two types of data are considered: ordered in time and uniformly mixed. The classification accuracy was assessed by calculating the area under the ROC curves with cross-validation for a different number of attributes. Results: a comparative analysis of observation labeling methods showed the advantage of the "completely normal observation" approach over the "majority vote" approach without "weighting". It is shown that the classification accuracy on mixed data is 7% higher compared to the variant of data ordering in time. The accuracy of the algorithm was investigated for a different number of attributes using the "completely normal observation" approach. The maximum achieved classification accuracy was about 96% when working with 6 attributes, with uniform mixing of the input dataset. A further increase in the number of attributes leads to a decrease in the average classification accuracy due to an increase in the proportion of anomalous observations. It is shown that when using uniform mixing of input data, the gain in accuracy can be increased by 15–20%. Practical relevance: the algorithm demonstrates an exponential growth in the consumption of computing resources with an increase in the amount of input data. Discussion: to achieve the maximum classification accuracy with acceptable resource consumption, it is necessary to form a compact set of input data, which most fully reflects the functioning of the computer system in normal mode.

Introduction: radio communication in the decameter range is actively used for communication in remote and hard-to-reach regions of the world. Decameter communication is also a relevant type of radio communication for regions that have suffered serious damage due to natural disasters. The relevance of using decameter radio communication in the above cases is due to the fact that this technology can offer reliable and cheap solutions. The second area of application of decameter radio communications is communications in the Arctic and Antarctic. Practical significance: when receiving signals with a spread spectrum, it becomes necessary to take into account the effect of the frequency dispersion of the ionospheric channel, since it leads to significant distortions of the useful signal and a decrease in the quality of communication in general. An urgent task is to estimate the parameters of the frequency dispersion of the ionospheric channel and to develop algorithms and devices for compensating dispersion distortions of broadband signals. Discussion: this article presents algorithms for estimating and compensating the dispersion distortions of wideband signals in the HF channel. The subbanding estimation method and maximum likelihood estimation (MLE) of the slope of the dispersion characteristic (the slope of DC) are studied. In addition, this article examines the joint MLE of the slope of DC and other parameters of the wideband signal and offers three methods of dispersion distortion compensation. The first method of compensation is a matched filter compensation. The second one is compensation based on the filter bank. Finally, the third method uses a tracking compensator to solve the problem. The experimental results demonstrated in the article were carried out on a one jump track with a length of about 2900 km.

Published: September 2022

This paper aims to devise a data flow model of computation for signal processing applications in which the operational nodes are signal/image processing functions such as Pixsum, Edge, Smooth. These functions are configured during run time from a pool of reconfigurable FPGAS. Thus because of the data flow model of computation, the signal processing functions execute concurrently. At the same time, these functions by exploiting their inherent spatial parallelism execute at high speed. There is a two fold speed up in the execution of image/signal processing applications one at the architecture level wherein a node of the dataflow model executes a digital signal processing (DSP) function rather than a low level machine operation. The second speed up is due to the fact that each DSP function is configured to execute in an FPGA by using maximally the concurrent operations that such a function permits. Another significant benefit that arises from our proposed architecture is that by reconfiguring an FPGA for a DSP function at run time, the reusability of the hardware elements results in reduced cost of operations. In this paper we provide an outline of the data flow architecture and its operational aspects.

In order to investigate the effect of asynchronous fast frequency hopping-multiple access (FFH-MA) systems due to the frequency offset, we evaluate the bit error rate (BER) performance, using noncoherent Mary frequency shift keying (FSK) modulation in the Rayleigh fading channel. While the frequency offset increases at a given signal to noise ratio (SNR), the BER is severely degraded due to the loss of orthogonality of received symbols. With 10% frequency offset, about 5 dB SNR is required additionally to obtain 2 x 10-3 BER, compared to that in the perfectly frequency synchronized case. For the SNR of more than 20 dB, the threshold level of the receiver suffering from the frequency offsets should be greater than that of the perfectly synchronized receiver.

Published: September 2022

The H.264 video coding standard provides a compression gain of 1.5 x 2.0 x over H.263 and MPEG- simple profile. One of the major differences between H.263 and H.264 is the transform coding. The transforms of H.264 employ only integer arithmetic operations such as additions and shifts without multiplications, with coefficients and scaling factors that allow for 16-bit arithmetic computation on first-level transforms. The integer transforms also solve the mismatch problem like H.263. These changes lead to a significant complexity reduction, but with only less than 0.02 dB decrease in PSNR. A novel parallel 4x4 multiple transforms architecture for H.264 is presented in this paper. This architecture is based on Wallace trees and can process 4 inputs in parallel. This architecture has been designed and synthesized in SMIC 0.18um technology. The result shows that this architecture can achieves above 1,200M pixels/sec throughout and consume only 5625 gates. The timing-area property of this architecture is improved compared with the previous architecture.

The aim: To analyse the value priorities of first-year medical students and outline areas of educational work to develop a system of professional values of future doctors who are able to work in circumstances of challenges of the time, as well as military conflicts.
Materials and methods: The method of questionnaires involving the students of Ternopil National Medical University from Ukraine and India was used, as well as the method of content analysis of students’ creative work. At the final stage of the study, essays written by Ukrainian first-year students on the day of the beginning of the war in Ukraine on February 24, 2022 were analysed.
Results: The desire to help people was the motive to enter a medical university for the majority of both Ukrainian and international students. Besides, Ukrainians identified civic values that are important in wartime: unity, national consciousness, struggle. In their opinion, the first day of the war determined the splash of anti-values: panic, fear, confusion. However, a similar study conducted ten days after the start of the war showed increase of confidence in victory, the levelling of negative emotions among Ukrainians. Therefore, the issue of the dynamics of values in wartime should be studied more.
Conclusions: Institutions of higher medical education should maintain a high intrinsic motivation of students in their altruistic striving to serve people, and improve the adaptation of first-year students, especially international ones. In wartime, it is necessary to intensify the educational work regarding ethical and spiritual development for strengthening the psychological well-being of students.

Published: September 2022

We have described two clinical cases of severe malaria caused by different pathogens: Pl. falciparum and Pl. malaria, common to which there was a severe course, complicated by acute renal failure and hemolytic anemia.
In a detailed analysis of both clinical cases, Patient 1 had acute kidney damage arose after the increase of anemia and thrombocytopenia, in combination with hemoglobinuria. This shows that the leading mechanism of kidney injure in this case is acute tubular necrosis, due to the toxic effects of free hemoglobin and sequestration in the capillaries of the glomerulus. A Patient 2 had a significant increase of anemia after appears of acute kidney damage; there was no hemoglobinuria, however, significant leukocytosis was observed. It seems, that the leading mechanism in this case is immune-mediated kidney injure or due to hypoperfusion of kidney tubules with the development of acute interstitial nephritis or immune complex glomerular injure with the development of glomerulonephritis, or a combination of them.
A detailed analysis of the described two clinical cases of severe malaria caused by Pl. falciparum and Pl. malaria, respectively, and complicated by acute renal failure and hemolytic anemia, suggests that the pathogenetic mechanisms and severity of kidney damage depend on the type of malaria.

Authors: Jiang Sheng , Yang Jing
Published: September 2022

Type 2 diabetes mellitus patients often suffer from kidney damage, which is more serious than in ordinary people. The insulin-like growth factor (IGF) system has synergistic effects with other hormonal axes and has an essential role in glucose metabolism and type 2 diabetes. The study aimed to observe the association of IGF-1 and IGF factor-binding protein-3 (IGFBP-3) with estimated glomerular filtration rate (eGFR) in patients with type 2 diabetes mellitus. We recruited 521 patients with type 2 diabetes from the Endocrinology Department of the First Affiliated Hospital of Xinjiang Medical University from March 1, 2021, to December 20, 2021. The clinical data we collected were analyzed to determine the association of IGF-1 and IGFBP-3 with eGFR in patients with type 2 diabetes. Spearman correlation analysis showed that eGFR was positively correlated with IGF-1 and IGFBP-3 in all subjects (P = 0.044 and P = 0.004, respectively). We developed a linear regression model. In the multiple linear regression model, serum IGF-1 and IGFBP-3 were positively correlated with eGFR (β = 0.03, 95% CI = 0.01 – 0.06; P = 0.009 and β = 1.29, 95% CI = 0.09 – 2.49; P = 0.035). The results of the correlations were further validated. This preliminary study demonstrated positive associations of serum IGF-1 and IGFBP-3 levels with eGFR in patients with type 2 diabetes.
Tiangong Louge in Eastern Pure Land Illustrations of the Medicine Buddha – A Secondary Publication
Authors: You Yiming , Zhu Yongchun
Published: September 2022

After the arrival of Buddhism in China, the foreign concept of heavenly buildings merged with the indigenous Tang-Song architecture into what became known as tiangong louge (heavenly palaces). Through comparison with Song building standards (Yingzao Fashi), this paper analyzes the architectural representations of tiangong louge in Eastern Pure Land illustrations of the Medicine Buddha. What becomes immediately apparent is that Yingzao Fashi describes only a few specific buildings (dianshen, chalou, jiaolou, xiewu, xinglang), whereas the Pure Land illustrations depict a greater diversity and variety of forms (for example, sanmen). A possible reason for this is that the idea of the Eastern Pure Land underwent significant changes before the Yingzao Fashi was compiled. Another reason is that the belief in the Eastern Pure Land was always rooted in reality and the actual conditions of the site. Additionally, Eastern Pure Land illustrations reveal four different types of clustered design: open foreground, one courtyard; open foreground, two courtyards; closed foreground, one courtyard; and closed foreground, two courtyards.

Authors: Komarytsia Mariana
Published: September 2022

The article focuses on the journalistic and literary achievements of Sofia Parfanovych – a doctor, writer, opinion journalist, editor, and a public figure – in the context of interdisciplinarity. Her active public stance as one of the leaders of the Ukrainian temperance society Vidrodzhennia, a member of the Ukrainian Medical and Hygienic Society, and Shevchenko Scientific Society encouraged educational activities in the Galician interwar press. She collaborated with periodicals such as Vidrodzhennia, Zhinocha Dolia, Likarskyi Vistnyk, Narodnie Zdorovlia, Nova Khata, etc. They published articles, stories, and discussions on a healthy lifestyle, healthy eating and threats posed by tobacco and alcohol, special attention was given to women’s health and child care. Many publications combined journalism and literature. For purely literary works – short stories and essays – O. Parfanovych used her experience as a medical practitioner. They were first published in the press (Nazustrich, Dilo, etc.), and later were included in the collections Tsina Zhyttia (Lviv, 1937) and Inshi Dni (Augsburg, 1948), producing strong reverberations in the Ukrainian literary environment. The article elaborates on a broad panorama of reception – i.e., reviews published in 1937 in the periodicals such as Dzvony, Zhinocha Dolia, Nova Zoria, Nova Khata, and Ukrayinska Knyha, written by by M. Hnatyshak, O. Duchyminska, O. Mokh, M. Rudnytskyi, as well as reviews by Yu. Sherekh and V. Nesterovych of the MUR (Artistic Ukrainian Movement) era. Critics argued that the first collection mostly includes «observations of life», and the second focuses on studying the laws of life with greater philosophical and psychological depth. The reviewers’ debates are analysed on a comparative basis, factors associated with mentality and gender are shown to account for differences in approaches while emphasizing the clear-cut national principles of the writer’s creative work.

Published: September 2022

This study assesses the impact of capital structure on the risk-taking of Vietnamese commercial banks in the period 2012–2020. The study uses the system GMM regression model (SGMM) to estimate the results based on panel data collected by year from financial statements of 30 Vietnamese commercial banks. The variable representing bank risk-taking is Z-score; the variables representing the capital structure of commercial banks are customer deposits and non-deposit liabilities. Research results show that customer deposits and non-deposit liabilities increase the risk-taking of commercial banks. From the findings of this study, bank administrators will have a basis to decide on the appropriate capital structure and bring value to the bank.
Cytochrome P450 monooxygenase-mediated tailoring of triterpenoids and steroids in plants
Authors: Malhotra Karan , Franke Jakob
Published: September 2022

The cytochrome P450 monooxygenase (CYP) superfamily comprises hemethiolate enzymes that perform remarkable regio- and stereospecific oxidative chemistry. As such, CYPs are key agents for the structural and functional tailoring of triterpenoids, one of the largest classes of plant natural products with widespread applications in pharmaceuticals, food, cosmetics, and agricultural industries. In this review, we provide a full overview of 149 functionally characterised CYPs involved in the biosynthesis of triterpenoids and steroids in primary as well as in specialised metabolism. We describe the phylogenetic distribution of triterpenoid- and steroid-modifying CYPs across the plant CYPome, present a structure-based summary of their reactions, and highlight recent examples of particular interest to the field. Our review therefore provides a comprehensive up-to-date picture of CYPs involved in the biosynthesis of triterpenoids and steroids in plants as a starting point for future research.

The energy storage capacity of latent heat thermal energy storage systems is high therefore these systems are efficient among all other thermal heat storage. This study experimentally investigates the charging and solidification of stearic acid (C18H36O2) in the finned triplex pipe heat exchanger with holes on the fin surface. The melting and discharging of stearic acid are carried out at steady inlet heat transfer fluid (HTF) i.e., water temperature. This study also investigates the result of the change in HTF flow rate on solidification and melting of phase change material. Finally, the study focuses on the comparison of average effectiveness for finned triplex tube heat exchanger and finned triplex tube with cylindrical holes on fin surface with rates of 0.33 and 0.43 Kg/s. The results showed that the average effectiveness with a finned triplex tube with a perforated fin surface is 4% more than that of a finned triplex tube at 0.33 Kg/s whereas it is 5 % more at 0.43 Kg/s during the charging process. On the other side during discharging process average effectiveness is 14 % more at 0.33 Kg/s and 11 % at 0.43 Kg/s.

Pembangunan ekonomi dan pengelolaan ekologi adalah sebuah keniscayaan yang terjadi seiring dengan perkembangan pembangunan. Untuk menyeimbangkan, konsep pembangunan berkelanjutan diperkenalkan sejak 2015 dengan framing TPB 2030. Menyambut ambisi TPB 2030, khususnya energi yang dapat diakses seluruh masyarakat dan bersih, diperlukan kerjasama yang baik antara pemerintah pusat dan daerah dalam menyusun strategi pengembangan masing-masing sesuai dengan prinsip otonomi daerah. Dalam UU No.3 Tahun 2020 tentang Minerba, Pemerintah Daerah berperan mulai proses perencanaan, penyusunan strategi, penyusunan kebijakan hingga penerbitan izin. Kontribusi Pemerintah Daerah juga disebutkan dalam RUU Energi Baru dan Terbarukan yang sedang dirancang oleh Legislator. Oleh karena itu, Pemerintah Daerah memiliki peranan penting dalam mewujudkan keselarasan atas pengelolaan lingkungan dan kegiatan eksplorasi dalam konsep regional green legislation. Konsep regional green legislation adalah sebuah konsep yang sesuai dengan capaian TPB 2030 Nasional dan merupakan implementasi asas otonomi daerah. Tulisan ini akan membahas tentang implementasi otonomi daerah dalam konsep regional green legislation, peran pemerintah daerah dalam aktivitas eksplorasi berdasarkan prinsip pembangunan berkelanjutan, dan model ideal regional green legislation.

Evidence of a relation between the mass accretion rate and the disk mass is established for young, Class II pre-main-sequence stars. This observational result opened an avenue to test theoretical models and constrain the initial conditions of disk formation, fundamental in the understanding of the emergence of planetary systems. However, it is becoming clear that planet formation starts even before the Class II stage, in disks around Class 0 and I protostars. We show for the first time evidence for a correlation between the mass accretion rate and the disk mass for a large sample of Class I young stars located in nearby (<500 pc) star-forming regions. We fit our sample, finding that the Class I object relation has a slope flatter than Class II stars, and the former have higher mass accretion rates and disk masses. The results are put in context of disk evolution models.
Cooling Envelope Model for Tidal Disruption Events
Authors: Metzger Brian D.
Published: September 2022

We present a toy model for the thermal optical/UV/X-ray emission from tidal disruption events (TDEs). Motivated by recent hydrodynamical simulations, we assume that the debris streams promptly and rapidly circularize (on the orbital period of the most tightly bound debris), generating a hot quasi-spherical pressure-supported envelope of radius R

, envelope heating from fallback accretion is subdominant compared to the envelope cooling luminosity except near optical peak (where they are comparable). Envelope contraction can be delayed by energy injection from accretion from the inner envelope onto the SMBH in a regulated manner, leading to a late-time flattening of the optical/X-ray light curves, similar to those observed in some TDEs. Eventually, as the envelope contracts to near the circularization radius, the SMBH accretion rate rises to its maximum, in tandem with the decreasing optical luminosity. This cooling-induced (rather than circularization-induced) delay of up to several hundred days may account for the delayed onset of thermal X-rays, late-time radio flares, and high-energy neutrino generation, observed in some TDEs. We compare the model predictions to recent TDE light-curve correlation studies, finding both agreement and points of tension.

Authors: Martínez-Domínguez Lilí , Nicolalde-Morejón Fernando , Vergara-Silva Francisco , Stevenson Dennis Wm.
Published: September 2022

Ceratozamia (Zamiaceae, Cycadales), is a member one of the most endangered seed plant groups. Species of Ceratozamia grow from near sea level up to 2,100 meters in Mexico and Mesoamerica. We present a modern taxonomic treatment of Ceratozamia, based on fieldwork combined with detailed study of herbarium specimens in and from Mexico and Central America. This new revision is based on incorporation of morphological, molecular and biogeographic data that have been previously published in circumscriptions of species complexes by our group. Detailed morphological descriptions of the 36 species of Ceratozamia are provided and relevant characters for the genus are discussed and described. A majority are endemic to Mexico and are concentrated at high elevations in mountainous areas. Synonymies, lectotypifications, etymologies, taxonomic notes, distribution maps, illustrations and detailed species-level comparisons are included, as well as a dichotomous key for identification of all species. Data on distributional ranges and habitats of all species are summarized. Ceratozamia osbornei D.W.Stev., Mart.-Domínguez & Nic.-Mor., sp. nov. is described from evergreen tropical forests of Belize and we highlight new populations and distributional ranges for C. subroseophylla Mart.-Domínguez & Nic.-Mor. and C. vovidesii Pérez-Farr. & Iglesias in the Mesoamerican region.
