Subnoise optical covert communication based on amplified spontaneous emission light
Authors: Liu Zhanqi , Zhu Huatao , Zhang Xin , Chen Shuwen , Xu Xiangming , Li Feiyu
Published: October 2023

Amplified spontaneous emission (ASE) light is a common noise in optical communication systems with optical amplification, and a suitable optical carrier for optical covert communication. To deeply covert the secure signal, an in-band subnoise optical covert communication scheme is proposed and demonstrated by a proof-of-concept experiment. The power spectral density of optical secure channel is 10 dB less than the optical noise in the public channel. The covert signal is hidden in both optical and electrical domain, and can be transmitted with error-free. The trade-off between covertness and availability is discussed.
Polarization multiplexing silicon photonic optical phased array with a wide scanning range
Authors: Zhao Shi , Lian Daixin , Chen Jingye , Dai Daoxin , Shi Yaocheng
Published: October 2023

We propose and experimentally demonstrate a polarization multiplexed silicon optical phased array (OPA) with a wide scanning range. The two polarization states share the same power splitter tree and the phase shifter array. A polarization switch is introduced in front of the power splitter tree to manipulate the polarization state of the light in OPA. Through a polarization splitter–rotator (PSR), the light of two polarization states propagates into the superlattice grating antenna array. The wavelength tuning efficiency could be doubled by optimizing the parameters of the waveguide grating. We demonstrate the scheme on the commonly used 220 nm silicon-on-insulator (SOI) platform. Experimental results indicate that the 24.8° vertical scanning range could be realized with a high wavelength tuning efficiency of 0.31°/nm. The measured field of view (FOV) is 24.8 × 60°.
Acoustic correlates of perceived personality from Korean utterances in a formal communicative setting
Authors: Song Jieun , Kim Minjeong , Park Jaehan
Published: October 2023

The aim of the present study was to find acoustic correlates of perceived personality from the speech produced in a formal communicative setting–that of Korean customer service employees in particular. This work extended previous research on voice personality impressions to a different sociocultural and linguistic context in which speakers are expected to speak politely in a formal register. To use naturally produced speech rather than read speech, we devised a new method that successfully elicited spontaneous speech from speakers who were role-playing as customer service employees, while controlling for the words and sentence structures they used. We then examined a wide range of acoustic properties in the utterances, including voice quality and global acoustic and segmental properties using Principal Component Analysis. Subjects of the personality rating task listened to the utterances and rated perceived personality in terms of the Big-Five personality traits. While replicating some previous findings, we discovered several acoustic variables that exclusively accounted for the personality judgments of female speakers; a more modal voice quality increased perceived conscientiousness and neuroticism, and less dispersed formants reflecting a larger body size increased the perceived levels of extraversion and openness. These biases in personality perception likely reflect gender and occupation-related stereotypes that exist in South Korea. Our findings can also serve as a basis for developing and evaluating synthetic speech for Voice Assistant applications in future studies.

Silver nanoparticles (AgNPs) were prepared by co-precipitation method using a capping agent, PEG-4000 (polyethylene glycol). The synthesized AgNPs were characterized using UV-visible, FTIR, SEM, EDX and TEM techniques. The bandgap energy of snythesized nanoparticles was determined using UV-visible spectra and found to be 3.07 eV. The particle size of nanoparticles calculated from the TEM and XRD pattern was in the range of 10-23 nm. The degradation efficiency of PEG capped AgNPs towards methylene blue (MB) dye under solar radiation was 63.78%. The photocatalytic degradation of MB dye follows the pseudo-first-order kinetics with an apparent rate constant of 1.1 × 10-2 min-1. The degradation products of MB dye during the photocatalytic process were identified using liquid chromatography-mass spectrometry (LC-ESI-TOF-MS). The antibacterial activity of synthesized PEG capped AgNPs using a disc diffusion method against four different Gram-positive and Gram-negative bacterial strains. The results showed that the synthesized nanoparticles could exhibit antibacterial activity. The anticancer activity of synthesized PEG capped AgNPs was tested against cancer cell lines such as A549 and HepG2. The results revealed that the synthesized PEG capped AgNPs have also shown an excellent anticancer activity with increasing their concentration. The antidiabetic activity of PEG capped AgNPs was studied against the a- lucosidase enzyme. The results confirmed that the synthesized AgNPs were shown a-glucosidase inhibition to 45.08%. The ABTS and DPPH radical scavenging activities were used to assay the antioxidant activity of synthesized PEG capped AgNPs.
A Study on the Role of the Ministry of Science and ICT in Nuclear Safety: Focusing on the Analysis of the Crisis Management Manual in Nuclear Safety
Authors:   Crisis and Emergency Management: Theory and Praxis, Kim Young Min , Kim Younhee
Published: October 2023

The Ministry of Science & ICT is a central agency in South Korea that oversees the Korea Atomic Energy Research Institute and the Korea Institute of Nuclear Safety as affiliated institutions. Furthermore, the ministry possesses a research reactor and is responsible for nuclear safety research. South Korea established a crisis management manual specifically for nuclear safety and nuclear safety field is coordinated by the Nuclear Safety and Security Commission, with relevant ministries holding operational manuals for nuclear safety crisis response. In this study, we analyze how central agencies with operational manuals for nuclear safety define the role of the Ministry of Science & ICT. Furthermore, through in-depth interviews with institutions related to nuclear safety, we extract the roles, tasks, and limitations that the Ministry of Science & ICT currently holds in the event of a radiological event. Finally, this study suggest the considerations such as establishing legal grounds, designating departments for roles specified in the standard manual, and exploring additional collaborative roles for the Ministry of Science & ICT’s crisis management manual.
A Comparative Study on Military Climate Crisis Management Policies in South Korea and the United States
Authors:   Crisis and Emergency Management: Theory and Praxis, Choi Sun Gyu
Published: October 2023

The climate crisis is emerging as an extreme crisis for the entire earth and humanity. Recently, the 6th IPCC report was published, but the forecast results are even more disastrous. Accordingly, the United States, one of the world's strongest developed countries, is doing its best to prepare active countermeasures against the climate crisis in the field of defense. In particular, the United States recognizes the climate crisis as one of the biggest threats to national security, and is designing policies based on this perception. However, in the case of South Korea, there is no continuously policy for responding to the climate crisis in the defense sector. In this study, in order to think about the problems of South Korea's defense climate crisis management policy, a comparative study was conducted with the U.S. defense climate crisis management policy. As a result, specific policies for each field are being conceived and implemented in the U.S. defense climate crisis management policy. However, in the case of South Korea, it was confirmed that there is no recognition of the climate crisis as a threat by the Ministry of National Defense and no specific policy.

Electrophysiological features and prognosis of peripheral neuropathy associated with IgM monoclonal gammopathy: a single-center analysis in South Korea
Authors: Kim Sooyoung , Lee Bit Na , Kim Seung Woo , Shin Ha Young
Published: October 2023

Background: Clinical spectrum of immunoglobulin M (IgM) monoclonal gammopathy varies from IgM monoclonal gammopathy of unknown significance (IgM-MGUS) to hematological malignancies. We evaluated the clinical features, electrophysiological characteristics, and prognosis of patients with peripheral neuropathy associated with IgM monoclonal gammopathy (PN-IgM MG).Methods: We retrospectively evaluated 25 patients with PN-IgM MG. Peripheral neuropathy was classified as axonal, demyelinating, or undetermined, based on electrophysiological studies. We classified the enrolled patients into the IgM-MGUS and malignancy groups, and compared the clinical and electrophysiological features between the groups.Results: Fifteen patients had IgM-MGUS and 10 had hematologic malignancies (Waldenström’s macroglobulinemia: two and B-cell non-Hodgkin’s lymphoma: eight). In the electrophysiological evaluation, the nerve conduction study (NCS) criteria for demyelination were met in 86.7% of the IgM-MGUS group and 10.0% of the malignancy group. In particular, the distal latencies of the motor NCS in the IgM-MGUS group were significantly prolonged compared to those in the malignancy group (median, 9.1 ± 5.1 [IgM-MGUS], 4.2 ± 1.3 [malignancy], p = 0.003; ulnar, 5.4 ± 1.9 [IgM-MGUS], 2.9 ± 0.9 [malignancy], p = 0.001; fibular, 9.3 ± 5.1 [IgM-MGUS], 3.8 ± 0.3 [malignancy], p = 0.01; P-posterior tibial, 8.3 ± 5.4 [IgM-MGUS], 4.4 ± 1.0 [malignancy], p = 0.04). Overall treatment responses were significantly worse in the malignancy group than in the IgM-MGUS group (p = 0.004), and the modified Rankin Scale score at the last visit was higher in the malignancy group than in the IgM-MGUS group (2.0 ± 1.1 [IgM-MGUS], 4.2 ± 1.7 [malignancy], p = 0.001), although there was no significant difference at the initial assessment. Conclusions: The risk of hematological malignancy should be carefully assessed in patients with PN-IgM MG without electrophysiological demyelination features.

Published: October 2023

Studies on species of the family Myrtaceae are mostly related to floristic surveys, reproduction involving large plant communities, and family taxonomy. Thus, the objective of this study was to elucidate aspects of the floral and reproductive biology, as well as floral visitors of ubajai (Eugenia myrcianthes Nied.). Studies were conducted on floral morphology and morphometry, identification of nectaries and structures attractive to floral visitors, characterization of floral visitors, stigma receptivity, and androecium maturation, pollen storage, in vitro viability testing, and characterization of the reproductive system. Ubajai flowers open at approximately 6:00 a.m., and their anthers are the main attractive structure to floral visitors. The main floral visitors and effective pollinators of ubajai are honeybees (Apis mellifera). The addition of 40% sucrose to the culture medium, using fresh pre-anthesis pollen, allows for a 90% germination rate. Ubajai pollen is recalcitrant, thus, it loses viability before 30 days of storage, even when stored in a refrigerator, freezer, liquid nitrogen, or natural environment. Ubajai can be considered a self-compatible plant; however, fertilization of flowers through cross-pollination also occurs, and apomixis does not occur.

Published: October 2023

The reinforcement of fused filament fabricated (FFF) components with continuous fibers allows for high versatility in the design of mechanical properties for a specific applications needs. However, the bonding quality between continuous fibers and the FFF matrix material has high impact on the overall performance of the composite. To investigate the bonding quality within additively manufactured (AM) continuous fiber reinforced specimens, tensile tests have been performed which revealed a sudden reduction in tensile stress, that most likely was not related to actual rupture of continuous fibers. Consequently, within this work we will expand upon these findings and present results of fast on-the-fly in-situ investigations performed on continuous carbon fiber reinforced specimens of the same AM build. During these investigations, specimens are loaded under the same conditions while fast XCT scans, with a total scan time of 12 seconds each, were performed consecutively. The resulting three-dimensional image data reveals internal meso- and macro-structural changes over time/strain to find the cause of the aforementioned reduction in tensile stress.

Authors: Rakhmatjati Pradana Bayu , R. W Calcarina Fitriani , Arifin Johan
Published: October 2023

Latar Belakang: Salah satu penyebab kesulitan weaning adalah gangguan neuromuskuler seperti polineuropati, miopati, dan spinal cord injury (SCI) segmen servikal di atas C5. Angka kegagalan ekstubasi berkisar pada 10-20% dari keseluruhan kasus intensive care unit (ICU) dengan angka kematian 25-50%. Ventilasi mekanik jangka panjang seringkali diperlukan pada pasien dengan cedera medula spinalis segmen di atas C5.Kasus: Kami laporkan 2 pasien; seorang laki-laki 22 tahun dengan diagnosis tetraparese spastik dengan lesi transversal total medula spinalis C5 et causa spinal cord injury, dan pada pasien kedua seorang laki-laki 34 tahun dengan diagnosis tetraplegia akut et causa canal stenosis servikal setinggi C1-3 et causa massa ekstradura et causa squamous cell carcinoma. Kedua pasien juga didiagnosis mengalami kejadian ventilator associated pneumonia (VAP), pasca prosedur pembedahan laminektomi. Penatalaksanaan berupa terapi antibiotik empiris dan de-eskalasi. Pembahasan: Sebagian besar gangguan neuromuskular yang mempersulit weaning diperoleh selama perawatan pasien di ICU. Fungsi sistem pernapasan pada pasien dengan cedera medula spinalis servikal memerlukan perhatian khusus, khususnya segmen level tinggi oleh karena keterlibatan saraf frenikus. Trakeostomi direkomendasikan dilakukan lebih awal setelah intubasi untuk menyederhanakan weaning. Komplikasi pascaoperasi harus diatasi agar tidak memperburuk luaran pasien. Kesimpulan: Kriteria weaning dan ekstubasi pada gangguan neuromuskuler dapat berbeda antar referensi, namun secara umum melibatkan vital capacity (VC), respiratory rate (RR), minute ventilation, PaO2, FiO2, PaCO2, rapid shallow breathing index, positive end-expiratory pressure (PEEP), dan kondisi klinis pasien. Selama weaning, bantuan ventilasi dilepas untuk sementara dan diselingi dengan periode istirahat.
Data-Driven Health Innovation and Privacy Regulation
Authors: Conti Chiara , D’Annunzio Anna , Reverberi Pierfrancesco
Published: October 2023

Data-driven health innovation may lead to develop targeted treatments using health data. We consider privacy-sensitive patients who may decide to share personal health data if compensated. Each patient does not internalize the impact of sharing data on drug innovation. We show that investment incentives in targeted treatments are too weak as long as such innovation has a public good nature so that patients can free ride on sharing health data. Then, privacy protection measures reducing data sharing risks can promote pharmaceutical R&D and social welfare.
On initial value problem for elliptic equation on the plane under Caputo derivative
Authors: Binh Tran Thanh , Thang Bui Dinh , Phuong Nguyen Duc
Published: October 2023

In this article, we are interested to study the elliptic equation under the Caputo derivative. We obtain several regularity results for the mild solution based on various assumptions of the input data. In addition, we derive the lower bound of the mild solution in the appropriate space. The main tool of the analysis estimation for the mild solution is based on the bound of the Mittag-Leffler functions, combined with analysis in Hilbert scales space. Moreover, we provide a regularized solution for our problem using the Fourier truncation method. We also obtain the error estimate between the regularized solution and the mild solution. Our current article seems to be the first study to deal with elliptic equations with Caputo derivatives on the unbounded domain.

Published: October 2023

The terahertz (THz) technology has fascinated lot of attention due to its enormous potential for a wide range of applications in the public, private and enterprise domains. This research work demonstrates the design structure and analysis of graphene based waveguide fed hybrid plasmonic THz patch antenna (HPTPA) constructed at around 3 THz. Hybrid plasmonic THz waveguide (HPTW) as a feeding line for the proposed THz patch antenna can increases antenna efficiency. The graphene is sandwiched between gallium arsenide (GaAs) and silver (Ag) to confine THz waves efficiently. Using mode analysis in finite element method for the proposed HPTW the propagation length, effective refractive index has been thoroughly examined. Based on the finite element method (FEM) approach, the results of the designed graphene-based waveguide fed HPTPA shows a high effective refractive index of 2.9, large propagation length of 230 µm, gain of 2.29 dBi, bandwidth of 200 GHz and efficiency of 85 % has obtained. The proposed graphene-based waveguide fed HPTPA could be beneficial to enable several photonic integrated circuit applications in next-generation wireless communication.

Published: October 2023

The risk of flooding is a destructive natural hazard, and it is increasing due to heavy rainfall and anthropogenic factors. Hydrologic–hydraulic models serve as valuable tools for flood forecasting and predicting future flow patterns. These models evaluate and simplify processes in ungauged basins. In this study, three hydrologic models (soil conservation service [SCS], Snyder, and Temez) were used to calculate synthetic unit hydrographs for the Humaya and Tamazula River (H-T-R) basin. Additionally, the flows derived from the three models were simulated in Hydrological Engineering Center River Analysis System for various return periods (2, 5, 10, 25, 50, and 100 years). The accuracy of the models SCS, Snyder, and Temez was evaluated using the root-mean-square error (1162.44, 144.76, and 2890.6); Nash–Sutcliffe efficiency (−51.12, 0.19, and −312.28); R
2 (0.97, 0.94, and 0.94), and kappa index (0.8534, 0.9895, and 0.7155), respectively. The data used in this study were obtained from a hydrometric station located on the Culiacan River. The main findings indicate that the Snyder model demonstrated a better predictive capability compared to the Temez and SCS models, albeit with a tendency to overestimate. Simulated flood depths are deeper in the upstream areas, particularly upstream from the Musala Island bifurcation on the Tamazula River, with values of 11.82 m for SCS, 9.76 m for Snyder, and 13.5 m for Temez. The simulation revealed potential overflow zones along the Tamazula River, particularly at the channel bifurcation and near the confluence with the Humaya River, during the 100 year return period simulation.
High speed 60 Gbps RGB laser based-FSOC link by incorporating hybrid PDM-MIMO scheme for indoor applications
Authors: Sharma Abhishek , Singh Kuldeep , Malhotra Jyoteesh
Published: October 2023

Visible Light Communication (VLC) systems enhanced by red, green and blue (RGB) lasers are at the forefront of indoor technology, offering dynamic lighting, high-speed data transfer, and energy efficiency. This innovative combination not only revolutionizes connectivity and illumination but also ensures privacy and security, making it a game-changer for smart homes, offices, and various indoor applications. In our research, we introduce a polarization division multiplexing and Multiple Input Multiple Output based (PDM-MIMO) system that carries 60 Gbps of data over a transmission range of 500 m in free space Channels. The utilization of the cost-effective on-off key (OOK) modulation format is attributed to its affordability in our transmission scheme. For parallel data transmission, three laser diodes in RGB were utilized. To enhance both the transmission range and reduce the Bit Error Rate (BER), MIMO scheme is employed. Our study presents simulation outcomes, conducted using OptiSystemTM software, that focus on evaluating the bit error rates for the proposed PDM-MIMO link. Our findings demonstrate successful 60 Gbps data transmission over 350 m in FSO with an acceptable BER, reinforced by clear eye diagrams. Introducing MIMO expands the range to 500 m while improving BER, paving the way for real-time experimentation and research advancement.

This meta-analysis aimed to evaluate the diagnostic accuracy of touch imprint cytology (TIC) for sentinel lymph node (SLN) metastases of patients with clinical node-negative early breast cancer. The PubMed, Web of Science, Embase, and the Cochrane Library databases were meticulously searched to retrieve literature published from January 2005 to September 2022 by two independent reviewers. The meta-analysis was performed using STATA16.0, Meta-Disc 1.4, and RevMan 5.4.9. According to the inclusion criteria, 4,073 patients from 13 studies were included in this meta-analysis. The pooled sensitivity and specificity of TIC for detecting SLN metastases were 0.77 (95% CI 0.66–0.85) and 0.99 (95% CI 0.97–1.00), respectively. The pooled positive likelihood ratio and negative likelihood ratio were 76.15 (95% CI 29.16–198.84) and 0.23 (95% CI 0.15–0.36), respectively. The pooled diagnostic odds ratio was 326.82 (95% CI 132.76–804.56) and the area under the sROC curve was 0.97 (95% CI 0.95–0.98), respectively. This meta-analysis revealed that TIC with high sensitivity and specificity is a feasibility and accuracy diagnosis technique for intraoperative detection of SLN metastases in breast cancer.

Short-Story Writing as the Art of Ordinary Aesthetics
Authors: Gouverneur Michel-Guy
Published: October 2023

Though ordinary aesthetics is self-evident as a principle, fruitful as a method, it remains partly undefined. It seems the major difficulty is to mark out its territory, so much so as, after Wittgenstein, it endorses the most part of what used to pertain to ethics. Our hypothesis is that starting from art forms may prove helpful in defining ordinary aesthetics; and the article suggests that short-story writing is a paradigmatic pathway to ordinary aesthetics as it is to the ethical unsaid.
Product of bi-dimensional VAR(1) model components.
An application to the cost of electricity load prediction errors
Authors: Janczura Joanna , Puć Andrzej , Bielak Łukasz , Wyłomańska Agnieszka
Published: October 2023

The multi-dimensional vector autoregressive (VAR) time series is often used to model the impulse-response functions of macroeconomics variables.
However, in some economical applications, the variable of main interest is the product of time series describing market variables, like e.g. the cost, being the product of price and volume.
In this paper, we analyze the product of the bi-dimensional VAR(1) model components.
For the introduced time series, we derive general formulas for the autocovariance function and study its properties for different cases of cross-dependence between the VAR(1) model components.
The theoretical results are then illustrated in the simulation study for two types of bivariate distributions of the residual series, namely the Gaussian and Student’s t.
The obtained results are applied for the electricity market case study, in which we show that the additional cost of balancing load prediction errors prior to delivery can be well described by time series being the product of the VAR(1) model components with the bivariate normal inverse Gaussian distribution.
Cutinolytic esterases are induced by growth of the fungus Trichoderma harzianum on glyceryl monostearate in solid-state fermentation
Authors: Conde-Ávila Victoria , Loera-Corral Octavio , Díaz Rubén , Sánchez Carmen
Published: October 2023

Cutinolytic esterase are enzymes utilized in a wide variety of industrial applications, and they are capable of degrading emerging environmental pollutants. Due to the application and importance of these enzymes, it is crucial to develop an efficient method for cutinase production using a cost-effective inductor and an efficient microbial production system. In this work, the growth and cutinolytic esterase production of Trichoderma harzianum were evaluated in glucose-yeast extract media containing different glyceryl monostearate (GMS) concentrations (1, 3, and 5 g/L). It was used as inducer in solid-state fermentation. A medium lacking GMS was used as control. Biomass production and enzyme productivity were higher in inducer-added (1 g/L) medium than in the control medium. T. harzianum produced constitutive and inducible cutinolytic esterase, in which production was enhanced by GMS. In GMS-added cultures, two bands with cutinolytic esterase activity (60 and 150 kDa approximately) were observed by zymography, which were not observed in control culture. GMS represents a promising inducer for cutinolytic esterase production by fungi. This research represents the first approach for the study of cutinolytic esterase production using a synthetic molecule as an inducer.

In ruin theory, the net profit condition intuitively means that the sizes of the incurred random claims are on average less than the premiums gained between the successive interoccurrence times. The breach of the net profit condition causes guaranteed ruin in few but simple cases when both the claims’ interoccurrence time and random claims are degenerate. In this work, we give a simplified argumentation for the unavoidable ruin when the incurred claims are on average equal to the premiums gained between the successive interoccurrence times. We study the discrete-time risk model with N ∈ N periodically occurring independent distributions, the classical risk model, also known as the Cramér–Lundberg risk process, and the more general Sparre Andersen model.

Nigeria, the largest country on the continent of Africa, has been fighting wars with the proclaimed terrorist group Boko Haram. Currently, Boko Haram has between 1,500 and 2,000 fighters; most documentation about them is either a position paper or a situation review. There is scanty data on the personality and psychological assessment of Boko Haram terrorists using a standardized self-report inventory. Hence, this study aims to describe and explore the profile of the Boko Haram suspects on all the scales of the Minnesota Multiphasic Personality Inventory-2-Restructured Form. Eleven respondents were purposefully recruited because they were the only ones incarcerated at the ‘Kiri-kiri’ Prison facility at the time of this research. Their scores on the inventory were descriptively analyzed. More of these terrorists endorsed significant scores or symptoms of emotional/internalizing dysfunction (EID), somatic complaints (RC1), antisocial behavior (RC4), ideas of persecution (RC6), gastrointestinal complaints (GIC), neurological complaints (NUC), suicidal/death ideation (SUI), anxiety (AXY), shyness (SHY), and disaffiliativeness (DSF), while elevated scores or severe symptoms were reported on stress/worry (STW) and psychoticism (PSYC-r). This research provides personality and psychological assessments of Boko Haram terrorists for the first time using MMPI-2-RF, though it is limited by sample size. Therefore, a larger sample size may be needed for further studies and the ability to make inferences and generalizations.

This study aims to examine the correlation between family functioning and self-disclosure among emerging adulthood. Family functioning is a process of physical and emotional interaction between family members in carrying out their duties and striving for the welfare of each member from the physical, social, and psychological aspects. Self-disclosure is the act of providing information about oneself that is usually hidden and not shared with others. This study used a quantitative method involving 111 college student respondents aged 18-25 years who study in West Jakarta and live separately from their parents. Family functioning is measured using the McMaster Model of Family Functioning adapted by Boterhoven de Haan. Meanwhile, self-disclosure is measured using the Self-Disclosure Scale based on the self-disclosure aspects according to DeVito and has been modified to the research context. The research analysis result showed that based on Pearson's correlation analysis, the family functioning has a significant and positive correlation with self-disclosure among emerging adulthood. The better family functioning and better self-disclosure help emerging adulthood in carrying out their academic activities. This study recommends for emerging adulthood to implement good communication patterns and self-disclosure to express themselves, share experiences, and deliver opinions to parents.

In this study, nonlinear control design is presented for trajectory tracking of Tricopter system. A Fractional Order Proportional Derivative (FOPD) controller has been developed. The performance of controlled Tri-copter system can be enhanced by suggesting modern optimization technique to optimally tune the design parameters of FOPD controller. The Spotted Hyena Optimizer (SHO) is proposed as an optimization method for optimal tuning of FOPD's parameters. To verify the performance of controlled Tricopter system based on optimal SHO-based FOPD controller, computer simulation is implemented via MATLAB codes. Moreover, a comparison study between SHO and Particle Swarm Optimization (PSO) has been made in terms of robustness and transient behavior characteristics of FOPD controller.

Published: October 2023

La presente investigación se aproxima a la Primera Carta de Pedro desde la pregunta por las claves de discernimiento en el discurso ético del autor. A modo de introducción se presenta un diagnóstico sobre el uso de la carta en distintas disciplinas teológicas. Metodológicamente se aborda el discurso aplicando un análisis retórico a fin de descubrir indicios de la estrategia del autor y, posteriormente, un análisis teológico con el objetivo de sistematizar lo que se expone acerca de la acción del Espíritu en el creyente. Los resultados de la investigación contribuyen a identificar pistas para el discernimiento en tres ámbitos: en relación con uno mismo, en las relaciones sociales y en las relaciones domésticas. El estudio concluye con la actualización de dichas claves como un aporte novedoso de la carta a la disciplina de la teología espiritual.

An analysis of the state of nutrition of people in Ukraine shows that the population does not eat well, which significantly worsens the state of their health and working capacity. The solution to the problem is possible through changes in the structure of nutrition, and above all, through an increase in the diet of vegetables and fruits of high quality, the varieties of which have been created using biofortification strategies. Biofortification is an innovative and promising approach in solving global problems related to nutrition. The goal of biofortification is to create plants with increased levels of the necessary functional ingredients absorbed from the soil, as well as those synthesized in the plant. Biofortification strategies consist in the development of optimal ways of mineral nutrition of plants, the creation of new species using molecular genetic approaches, and the use of traditional breeding methods. The purpose of the research is to analyze the modern experience of creating varieties of various fruit and vegetable crops with the help of biofortification strategies, which have an increased content of functional ingredients. Based on the literature review, it was established that for many years, an unconventional direction of selection has been developing – the creation of varieties and hybrids of fruits and vegetables with the recommended chemical composition. Created varieties of vegetables and fruits with increased protein content (nuts and legumes); starch (potato); carotenoids, dry matter, disaccharides (carrot, pumpkin); vitamin C, betanin, sugars (table beet); selenium (tomatoes); bioflavonoids, vitamin C (cabbage vegetables); macro- and microelements (bulb vegetables), etc. Such raw materials can be used to create special purpose products, which will significantly improve the quality of the population's diet and health. It is shown that the development of the non-traditional direction in breeding remains promising, and the study of samples of the domestic collection of agricultural crops and the selection of the best varieties from them for various directions of use, and especially for the production of special purpose products, is an important national economic and scientific task of an innovative nature that must be developed, therefore that the problem of improving the nation should come first.
MICROWAVE AND ULTRASONIC TREATMENT AS A PRELIMINARY STAGE OF OBTAINING WATER-SOLUBLE MANNAN FROM COFFEE SLUDGE
Authors: Naumenko K. , Kapustian A. , Gural L.
Published: October 2023

In recent years, interest in immunocorrectors of natural origin has increased significantly. Among them is a group of polysaccharides such as mannans. Mannans are polysaccharides composed of D-mannose residues as the main chain. They possess a number of properties: immunomodulatory, cancer-protective, antimicrobial, and normalize blood cholesterol levels. Mannans are present in a number of plants, algae and microorganisms. One of the promising sources of mannans can be coffee sludge, which is accumulated on an industrial scale at instant coffee companies. This article describes a biotechnological method for the production of water-soluble mannan from coffee sludge and investigates the possibility of increasing the yield of water-soluble low-molecular-weight mannan with the maximum content of physiologically active fractions by pretreating the raw material with ultrasound and ultrahigh-frequency radiation. The sludge was pretreated in an aqueous medium using ultrasound at 25, 35 and 40 kHz for 15 minutes and treatment in a 2.45 GHz ultra-high-frequency electric field with a power of 300 W, 600 W and 800 W for 5 minutes. Next, the physical disintegrate was treated with an enzyme preparation with beta-mannanase activity and centrifuged. The resulting water-soluble products were characterized by gel chromatography to determine the molecular weight distribution of the fractions of each sample. It was found that the pretreatment with ultrasound is expedient, since the total amount of fractions with a molecular weight of less than 20 kDa is almost 80%. The treatment of raw materials with microwave rays is inefficient and leads to an increase in fractions of molecular weight less than 1 kDa. Thus, varying the conditions of the preliminary physical treatment of coffee sludge allows to regulate the molecular weight distribution of water-soluble enzymolysis products and obtain products with the required range of molecular weight values.

In this study, the thermodynamic properties and anisotropic factors of perfect and defective tungsten were investigated through their correlation with elastic constants. The study examined sound velocities, Debye temperature, minimum thermal conductivity, melting point, and elastic anisotropy factors at various temperatures and pressures. The utilized elastic constants were calculated by molecular
dynamics simulations. We used three different interatomic potentials in the simulations involving two
embedded atoms and one modified embedded-atom method. The findings indicated that temperature and pressure were positively correlated with anisotropic factors, with increased values leading to an increase in metal anisotropy. Also, defects were found to cause an increase in anisotropy, with a single vacancy having a greater impact on elastic anisotropy compared to a central void in the crystal structure. The study also found that the fundamental thermodynamic characteristics of pure tungsten crystal including density, sound velocities, Debye temperature, and Grüneisen parameter in the ambient conditions for all three potentials were in good agreement with previous experimental and theoretical
calculations. The results showed that defective structures displayed the same trend as perfect crystals for elastic constant-related properties. The presence of defects in the crystal caused a decrease in thermodynamic properties at all temperatures and pressures, with the degree of decrease directly correlated with the fraction of crystal defects. The study also found that the minimum thermal conductivity as a key parameter of tungsten showed a downward trend with temperature and upward with pressure.
