Influence of symmetric/asymmetric boundaries on axisymmetric convection in a cylindrical enclosure in the presence of a weak vertical throughflow
subject: Axisymmetric convection; Chaos; Cylindrical enclosure; Newtonian-Boussinesq fluid; RayleighBard convection; Throughflow
description: The linear and nonlinear stability of axisymmetric convection of a viscous fluid in a cylindrical enclosure heated from below is investigated for various radius to height ratios. A weak vertical throughflow is imposed in a gravity-aligned or a gravity-opposing manner. Symmetric and asymmetric boundaries of free-free, rigid-rigid and rigid-free types are considered for lower and upper boundaries with isothermal temperature boundary condition. The side-walls are assumed to be rigid and adiabatic. A convergent Maclaurin series representation is considered for the finding of axial trial eigenfunctions. In order to corroborate the results of the present study with those of a previous investigation, the critical Rayleigh number and the number of radial rolls manifesting for any given aspect ratio are determined in the case of no throughflow and an exact match is found. Further, the influence of boundaries and the effect of throughflow on chaotic and periodic regimes of motion are studied with the help of a time series solution and the largest Lyapunov exponent as indicators of chaos. The novelty of the present study is the use of a Maclaurin series representation for the eigenfunctions of the linear problem and using the same in determining the solution with the convective mode. 2023 Elsevier B.V.

An Investigation of Complex Interactions Between Genetically Determined Protein Expression and the Metabolic Phenotype of Human Islet Cells Using Deep Learning
subject: BiLSTM; BLB; Deep learning; EfficientNet B0; eQTL; PIMA; Type 2 diabetes
description: The relationship between gene modules and several genome-scale metrics was examined, including heterozygosity that caused type 2 diabetes due to insulin deuteration, differential expression, genotyping association, methylation, and copy number changes. This work investigates the complex relationships between protein expression, genetic polymorphisms, and metabolic properties of human islet cells using expression quantitative trait loci (eQTL) detection. We looked at the genomic, transcriptomic, and proteomic information from islet cells in persons with type 2 diabetes. From the information from different levels, we noticed novel eQTLs that regulate crucial metabolic and signaling pathways in islet cells. Our study highlights the importance of a systems-level approach in understanding the complicated biological processes by highlighting the complexity of the link between genetic variants, protein expression, and metabolic abnormalities using the PIMA Indian dataset. Our findings provide novel insights into the molecular mechanisms behind islet cell failure in type 2 diabetes, potential targets for emerging treatment strategies, and the genomic implications of variations in gene expression, mutations, and other factors. To accomplish this purpose, we proposed a novel BLB model and obtained 99.89%. 2023, The Author(s), under exclusive licence to Springer Nature Singapore Pte Ltd.

Bharatanatyam and Art activism in the Networked Digital Space
subject: art activism; artistic innovations; Bharatanatyam; dance; social movements
description: All over the world, traditional models of art activism through dance involved performances that reached a limited audience, while the advent of networked digital spaces has vastly expanded the scope of art activism to a global level. Offering a qualitative netnographic exploration of how Bharatanatyam has been employed for such art activism in the digital space, this article examines the implications for this prominent traditional South Indian dance form in terms of stylistic changes as well as viewer reactions. Through content analysis of the viewer responses to ten popular renditions uploaded on YouTube over five years (20162020), we trace how the art form is evolving and how activist goals are reciprocated by the audience. Our findings confirm that Bharatanatyam has great potential to evolve by adapting novel social themes. However, while such contemporary renditions may elicit viewer responses that critically appraise specific social issues and pave the way for social change, the resulting innovations continue to co-exist with old conflicts and tensions about traditional art and its uses. 2023 The Author(s).

Prediction of the capture and utilization of atmospheric acidic gases by azo-based square-pillared fluorinated MOFs
description: More than the permissible limit of acidic gases like CO2, SO2, and NO2 in the atmosphere are responsible for the formation of acid rain, the greenhouse effect and many other undesirable environmental hazards. So, the capture and utilization of these gases are essential for mankind. Herein, we proposed an azo-based square pillared MOF, [Ni(MF5)(1,2-bis(4-pyridy)diazene)2]n, with the CUS metal site, i.e. M = Al/Fe, for the selective capture and conversion of acidic gas molecules into commodity chemicals such as cyclic carbonate, sulphite and nitrite. With the aid of Density Functional Theory (DFT), [Ni(MF5)(1,2-bis(4-pyridy)diazene)2]n has been optimized, and the specific force field is derived via guest-host interaction. The Grand Canonical Monte Carlo (GCMC) simulation has been used to explore the guest-host interactions over a wide range of pressures, and their respective stability under pre-humidification is evaluated. The adsorption prediction reveals that MFFIVE-Ni-apy have a higher adsorptive capacity (37.1 mmol g?1), and especially ALFFIVE-Ni-apy possesses a higher affinity towards guest molecules (CO2, SO2) rather than FEFFIVE-Ni-apy. Additionally, the adsorption of gases in the presence of humidity reveals that ALFFIVE-Ni-apy has an optimal adsorption capacity for all investigated acidic gases even at 38.5 RH%. The absorbed acidic gases on MFFIVE-Ni-apy were used for the theoretical investigations on cycloaddition with the aid of DFT as an application perspective of the toxic gases instead of expelling into atmosphere. The Climbing Image Nudged Elastic Band (CI-NEB) approach was used to discover the transition state in this scenario, in which the cycloaddition of adsorbed CO2, SO2, and NO2 gases with epoxides leads to the formation of cyclic carbonates, sulphites, and nitrates, respectively. 2023 The Royal Society of Chemistry.

Differential Approach of Bioremediation by Sclerotium rolfsii Towards Textile Dye
subject: Bioadsorption; Biodegradation; Malachite green; Rose Bengal; Sclerotium rolfsii
description: Synthetic dyes are extensively used in various industries and are one of the major contaminants of industrial effluents. Dyes being xenobiotic, carcinogenic, and toxic there is need for their effective removal and detoxification to conserve water resources. Tremendous research has been carried out to identify potent microorganisms that facilitate bioremediation of these harmful dyes. A static batch culture has proved white rot fungi Sclerotium.rolfsii as an efficient catalyst in bioremediation of textile dyes and to compare their efficiency in decolourisation of two different azo dyes. Studies revealed the organism employ different remedial approach to cationic dye (Malachite green) and anionic dyes (Rose Bengal). Decolourisation of malachite green was a gradual with degradation and bio-transformation to colourless, non-toxic by products while Decolourisation of rose Bengal was quick process of biosorption. S.rolfsii exhibited 89% of decolourisation of malachite green dyes at higher concentration of 900mg/L while 96% for rose Bengal at 900mg/L. The mechanism of dye decolourisation was proposed using the UV Vis spectrophotometry, FTIR, XRD, HPLC and SEM. Microbial toxicity studies confirmed the dye metabolites of degraded malachite green was less toxic compared to original dye. Com- prehensively studies illustrate the sustained application of S. rolfsii as model organism for bioremediation of complex industrial effluents due to its differential bio remedial approach can potentially decolourise or remove various dyes. 2023, Association of Biotechnology and Pharmacy.

Disentangling the two sub-populations of early Herbig Be stars using VLT/X-shooter spectra
subject: Circumstellar matter; Methods: data analysis; Stars: emission-line, Be; Techniques: spectroscopic
description: Context. Early Herbig Be (HBe) stars are massive, young stars accreting through the boundary layer mechanism. However, given the rapid (<2 Myr) evolution of early Herbig stars to the main-sequence phase, studying the evolution of the circumstellar medium around these stars can be a cumbersome exercise. Aims. In this work, we study the sample of early (B0-B5) HBe stars using the correlation between H? emission strength and near-infrared excess, complemented by the analysis of various emission features in the X-shooter spectra. Methods. We segregate the sample of 37 early HBe stars based on the median values of H? equivalent width (EW) and near-infrared index (n(J-H)) distributions. The stars with |H? EW| > 50and n(J-H) > -2 are classified as intense HBe stars and stars with |H? EW| < 50and n(J-H) < -2 as weak HBe stars. Using the VLT/X-shooter spectra of five intense and eight weak HBe stars, we visually checked for the differences in intensity and profiles of various HI and metallic emission lines commonly observed in Herbig stars. Results. We propose that the intense HBe stars possess an inner disk close to the star (as apparent from the high near-infrared excess) and an active circumstellar environment (as seen from the high H? EW value and presence of emission lines belonging to FeII, CaII, OI, and [OI]). However, for weak HBe stars, the inner disk has cleared, and the circumstellar environment appears more evolved than for intense HBe stars. Furthermore, we compiled a sample of ~58 000 emission-line stars published in Gaia DR3 to identify more intense HBe candidates. Further spectroscopic studies of these candidates will help us to understand the evolution of the inner (approximately a few au) disk in early HBe stars. The Authors 2023.

Environmentally responsible behaviour among the teachers: role of gratitude and perceived social responsibility
subject: Confirmatory factor analysis; Environmentally responsible behaviour; Gratitude; Perceived social responsibility; Positive emotion
description: Purpose: Based upon the broaden-and-build theory of positive emotions, this study aims to assess the role of perceived social responsibility (PSR) in mediating the relationship between gratitude and environmentally responsible behaviour (ERB) among teachers. Design/methodology/approach: Data were collected, following a correlational design, from a total of 292 school teachers in Kerala state, India. In total, 256 data were taken for final analysis. Out of the total participants, 63.3% were female and the remaining 36.7% were male. Confirmatory factor analysis was carried out to verify the factor structure and discriminant as well as convergent validity of the study variables. The relationship between gratitude and ERB with mediating role of PSR was tested. Findings: The mediation analysis output revealed that PSR fully mediates the effect of gratitude on ERB, and it is concluded from the findings of the study that ERB can be enhanced by humanizing the citizens to integrate social responsibility in their acts and promoting the significance of having positive emotions like gratitude to widen their thoughtaction repertoires. Research limitations/implications: In line with the broaden-and-build theory, a positive state of mental faculty can be a prime facilitator to increase concern for green environments as an outcome of an expanded thoughtaction repertoire. The findings imply the importance of inculcating enduring personal resources like the sense of gratefulness as it weighs the effect of producing altruistic acts like ERB along with many other benefits associated with having a positive emotion which is obviously considered to be a fair contribution to serve social resources in the community. Social implications: The study findings can be an inspiration for the formation of policies to encourage pro-environmental behaviour and to further expansion of policies like national education policy of India. As teachers being the facilitators of knowledge and wisdom, they are…

Autism spectrum disorder detection using brain MRI image enabled deep learning with hybrid sewing training optimization
subject: Autism spectrum disorder; Hybrid sewing training optimization; Magnetic resonance imaging; Pivotal region extraction; Sewing training-based optimization
description: Autism spectrum disorder (ASD) is brain enabled disorder representing behaviors in a repetitive manner and social deficits. In this paper, ASD is diagnosed using brain magnetic resonance imaging (MRI) enabled deep learning with a hybrid optimization algorithm. Also, the hybrid optimization algorithm utilized is hybrid sewing training optimization (HSTO) which trains ZFNet for ASD detection. Pre-processing of the MRI image is done by Wiener filter and the filtered image is fed for region of interest extraction. Moreover, pivotal region extraction is carried out by the proposed HSTO, which is finally allowed for ASD detection by ZFNet. The proposed HSTO is formed by combining sewing training-based optimization and hybrid leader-based optimization. Furthermore, the performance of HSTO_ZFNet is found by five performance metrics of accuracy with 95.7%, true negative rate with 92.6%, true positive rate with 93.7%, false negative rate with 68.7%, and false positive rate with75.9%. 2023, The Author(s), under exclusive licence to Springer-Verlag London Ltd., part of Springer Nature.

How does anticipatory trauma reaction and climate-friendly behaviour make an affect at the individual level? The role of social norms and self-efficacy
subject: anticipatory trauma reaction; climate change; climate-friendly behaviour; environmental sustainability; perceived self-efficacy; perceived social norms; SmartPLS software
description: Climate change is unavoidable and requires serious consideration at both the organizational and individual levels. Climate change mitigation, reduction in greenhouse gas emissions globally and climate financing for developing countries and so forth are key issues and challenges toward environmental sustainability. This paper aims to develop a framework for climate-friendly behaviour (CFB) for environmental sustainability from an individual perspective. The present study recognizes the role of social norms and self-efficacy in developing positive behaviour toward environmental sustainability. On the proposed integrated CFB framework of value-belief-norms (VBN) and self-efficacy theory, this study is a unique conceptual-empirical scholarly development, examining individual-level contemplation toward climate-supportive policy measures. This research evaluates the relationship between anticipatory trauma reaction (ATR) and CFB in the presence of perceived social efficacy (PSE) and perceived social norms (PSN) as moderators and mediators. We have used the survey method to examine a sample of 238 respondents and assess the structural equation modelling analysis and PLS predictions using SmartPLS software. The findings indicate that climate change-related anxiety-driven ATR facilitates CFB among individuals. Next, the study adds value to VBN theory as the results also suggest that PSN improve ATR's positive impact on CFB. This work further expands the horizon of self-efficacy theory by arguing that PSE transmits the positive effect of ATR on CFB. The study delivers many worthy theoretical and practical contributions toward climate change policies and environmental sustainability implications. 2023 ERP Environment and John Wiley & Sons Ltd.

A review of alternative proteins for vegan diets: Sources, physico-chemical properties, nutritional equivalency, and consumer acceptance
subject: Algal protein; Alternative protein; Meat alternate; Mycoprotein; Plant-based protein; Protein recovery; Sustainable development; Vegan diet
description: Alternate proteins are gaining popularity as a more sustainable and environmentally friendly alternative to animal-based proteins. These proteins are often considered healthier and are suitable for people following a vegetarian or vegan diet. Alternative proteins can be recovered from natural sources like legumes, grains, nuts, and seeds, while single cell proteins (mycoproteins), and algal proteins are being developed using cutting-edge technology to grow fungus, yeast and algal cells in a controlled environment, creating a more sustainable source of protein. Although, the demand for alternative protein products is increasing, there still happens to be a large gap in use among the general consumers mainly stemming from its lower bioavailability, lack of nutritional equivalency and reduced digestibility compared to animal proteins. The focus of the review is to emphasize on various sources and technologies for recovering alternative proteins for vegan diets. The review discusses physicochemical properties of alternative proteins and emphasise on the role of various processing technologies that can change the digestibility and bioavailability of these proteins. It further accentuates the nutritional equivalency and environmental sustainability of alternative protein against the conventional proteins from animals. The food laws surrounding alternative proteins as well as the commercial potential and consumer acceptance of alternative protein products are also highlighted. Finally, key challenges to improve the consumer acceptability and market value of plant-based proteins would be in achieving nutrient equivalency and enhance bioavailability and digestibility while maintaining the same physicochemical properties, taste, texture, as animal proteins, has also been highlighted. 2023 The Authors

A Search for X-Ray/UV Correlation in the Reflection-dominated Seyfert 1 Galaxy Markarian 1044
description: Correlated variability between coronal X-rays and disk optical/UV photons provides a very useful diagnostic of the interplay between the different regions around an active galactic nucleus (AGN) and how they interact. AGNs that reveal strong X-ray reflection in their spectra should normally exhibit optical/UV to X-ray correlation consistent with reprocessingwhereas the optical/UV emission lags behind the X-rays. While such correlated delay has been seen in some sources, it has been absent in others. Mrk 1044 is one such source that has been known to reveal strong X-ray reflection in its spectra. In our analysis of three long XMM-Newton and several Swift observations of the source, we found no strong evidence for correlation between its UV and X-ray lightcurves both on short and long timescales. Among other plausible causes for the nondetection, we posit that higher X-ray variability rather than UV and strong general relativistic effects close to the black hole may also be responsible. We also present results from the spectral analysis based on XMM-Newton and NuSTAR observations, which show the strong soft X-ray excess and iron K? line in the 0.3-50 keV spectrum that can be described by relativistic reflection. 2023.

A Model for Detecting Type 2 Diabetes Using Mixed Single-Cell RNA Sequencing with Optimized Data
subject: AChOA; Gene; Monte Carlo; ODBN; scRNA-seq; Type 2 diabetes
description: Diabetes is a critical disease and is crucial to personage agility. Type 2 Diabetes (T2D) accounts for 92% of epithetical cases. This paper proposes an optimized type 2 diabetes detection model using mixed single-cell RNA sequencing (scRNA-seq) technology. Diabetes is a chronic metabolic disorder affecting millions of people worldwide. Early detection of the disease can greatly improve treatment outcomes, but current diagnostic methods have limitations. Our proposed model integrates scRNA-seq data from both human pancreatic beta cells to identify gene expression patterns associated with diabetes. Our study shows that the proposed model is highly accurate in identifying diabetes, achieving an area under the curve (AUC) of 0.98. We employed an optimized model to improve the detection of diabetes at an early stage, leading to better treatment outcomes and an improved quality of life for patients. We initially incorporated optimal features from the dataset using the Monte Carlo (MC) feature selection method. This method helped us to estimate the relative importance (RI) score of each gene or feature, which is then used to rank the features. Further, we proposed an optimized deep belief network (ODBN) as a classification model to classify T2D and non-diabetes. To improve the performance of ODBN, an adaptive chimp optimization algorithm (AChOA) is introduced to optimize the weight parameters and achieved a performance accuracy of 96.57%. 2023, The Author(s), under exclusive licence to Springer Nature Singapore Pte Ltd.

description: Tungsten oxide (WO3) thin films were prepared on Corning (CG) and Fluorine doped tin oxide (FTO) glass substrates at partial pressure of oxygen (pO2) 4 10?2 Pa and 8 10?2 Pa using DC magnetron sputtering (DCMs). In this work, we have varied the deposition parameters like pO2, target currents, and temperature. At pO2 4 10?2 Pa and 8 10?2 Pa samples were deposited at target currents of 50 mA and 100 mA, the maintained growth conditions are RT (substrate temperature 28 C), Pre annealed (substrate temperature 400 C), and Post annealed (annealing temperature 400 C). The samples were systematically characterized for vibrational, structural, optical, and Electrochromic (EC) properties by using Raman, XRD, Uv-Vis spectrometer, and Electrochemical analyzer respectively. XRD analysis reveals that RT-deposited samples show amorphous nature and pre & post-annealed samples show a crystalline nature for both pO2. Optical transmittance was higher at RT-deposited samples at 50 mA (94% & 92%) and lower at 100 mA (87% & 85%) at the wavelength of 600 nm for both pO2. From CV analysis higher cathodic peak current density was observed in RT-deposited samples at 50 mA (?6.49 mAcm?2 & -13.80 mAcm?2) and lower at 100 mA (?5.25 mAcm?2 & -12.88 mAcm?2) for both pO2. The diffusion coefficient was observed at a higher target current at 100 mA (1.06 10?7 cm2/s & 9.20 10?8 cm2/s). For annealed samples optical and EC properties were decreased for both pO2. 2023 Elsevier B.V.

Measuring the Economic Burden of Health Conditions among White?Collar Employees: A Cross?Sectional Study from Delhi? NCR
subject: Direct cost; economic burden; health conditions; indirect cost; non-communicable diseases; white-collar employees
description: Background: In the past few decades, there has been a significant increase in healthcare expenditure due to the prevalence of health issues across the globe. This is primarily seen among white-collar employees due to the sedentary nature of their jobs, which affects their current earnings (Purchasing Power) directly due to the reallocation of their real income towards healthcare expenditure (Economic Burden) and indirectly by impacting work productivity through sick leaves. Aim: To measure the economic burden of disease(s) among white-collar employees, and to study the same across different socio-demographic variables. Methods: A cross-sectional study has been conducted in the region of Delhi-NCR among 357 white-collar employees. A random sampling method was adopted using a structured questionnaire. The questionnaire collected information regarding the direct and indirect costs of health conditions with a recall period of one month. The cumulative score of these monthly costs was converted to annual data to estimate the economic burden of the health conditions among the employees over a year. Results: As compared to Communicable diseases (16.24%), Non-communicable diseases (27.17%) were more prevalent among the respondents. Compared to other diseases, the employees suffering from Heart diseases (INR 7,62,237.50), Spinal health issues (INR 1,73,625.00), and Diabetes (INR 1,64,535.71) incurred more economic burden. At a 5% significance level, no significant difference was observed in economic burden for Gender and BMI. However, the economic burden was significantly different across the categories of Age and Monthly income. A positive association can be observed in economic burden with the increasing categories of age and monthly income. Conclusion: With the nature of sedentary work (desk jobs), white-collar employees are at a greater risk of exposure to various NCDs than CDs and incur a significant amount of out-of-pocket expenditure to manage their health status. 202…

Synthesis, Green Photoluminescence and Studies of Nonlinear Optical Spatial Self Phase Modulation Effect in 2D Ga2Te3 Nanosheets
subject: 2D Ga2Te3; 2D material; Liquid Phase exfoliation; Nonlinear Optics; Photoluminescence
description: The liquid-phase exfoliation (LPE) technique has been employed to prepare two-dimensional (2D) gallium telluride (Ga2Te3) nanosheets with an average thickness of ?2.4 nm and linear optical properties, including UV-visible absorption and photoluminescence (PL) emission characteristics of the sample in the green wavelength region are reported. The third-order nonlinear optical (NLO) responses of the colloidal suspension of 2D Ga2Te3 are determined at 532 and 632 nm wavelengths by a spatial self-phase modulation (SSPM) experiment. The value of the third-order NLO refraction coefficient (n2e) and effective susceptibility for monolayer (?(3)Mono) 2D Ga2Te3 under 532 (632) nm continuous wave (CW) excitation is extracted to be 2.60 10-7 (0.32 10-7) cm2/W and 1.12 10-9 (1.37 10-10) e.s.u., respectively. The origin of the observed SSPM patterns under 532 nm excitation was elucidated theoretically. Finally, the correlation of ?(3)Mono with the mobility of charge carriers for a vast number of 2D materials is utilized to establish the origin of the observed NLO effect under 532 nm pump laser radiation in the 2D Ga2Te3. Additionally, NLO absorption coefficients of 2D Ga2Te3 have been extracted using the femtosecond Z-scan technique at 800 nm. We observed a switching behavior (saturable to threephoton absorption) in the nonlinear absorption mechanism with different input peak intensities. The highest three-photon absorption coefficient of ?1.68 cm3/GW2 was observed for a 350 GW/cm2 peak intensity. We believe that such reports of interesting linear and NLO properties of this newly synthesized 2D material can be utilized in the future for a wide number of optoelectronic applications. 2023 American Chemical Society.

A MULTI-OBJECTIVE HUNTER-PREY OPTIMIZATION FOR OPTIMAL INTEGRATION OF CAPACITOR BANKS AND PHOTOVOLTAIC DISTRIBUTION GENERATION UNITS IN RADIAL DISTRIBUTION SYSTEMS
subject: Active power loss reduction; Capacitor bank placement; Distribution Generation; Hunter-Prey Optimization; PV-DG integration; Voltage stability
description: This article put forward the determination of the optimal siting and sizing of capacitor banks and PV-DG (Photo-Voltaic Distribution Generation) units in a radial distribution system. A modern population-based optimization algorithm, Hunter-Prey Optimization (HPO), is applied to determine the optimal capacitor bank and PV-DG placement. This algorithm, HPO, got its motivation from the trapping behaviour of the carnivore (predator/hunter) like lions and wolves towards their target animal like deer. The typical IEEE-33 & 69 test bus systems are scrutinized for validating the effectiveness of the suggested algorithm using MATLAB software R2021b version. The acquired results are collated with the existing heuristic algorithms for the active power loss criterion. The nominal or base values for system losses and voltage profile were considered for the comparison, with the results from HPO. The HPO application has an efficient performance in figuring out the most favourable location and capacity of the capacitor banks and PV DGs compared with the other techniques. 2023 by authors and Galileo Institute of Technology and Education of the Amazon (ITEGAM).

Design of reconfigurable multiplier-less filter structure based on IFIR for digital channelizer
subject: Cosine modulation technique (CMT); Digital channelizer; FIR filters; Interpolated finite impulse response (IFIR); Reconfigurable non-uniform sub-bands
description: The flexibility in frequency allocation is essential for high throughput satellites (HTS). The digital channelizer based transponder system has a crucial role in enhancing the performance of HTS. In this work, the design and implementation of a low computational complexity digital channelizer for HTS is proposed. The proposed reconfigurable filter structure for digital channelizer is to generate non-uniform and sharp transition width FIR filters for transponder of the satellite systems. The multipliers and group delay needed in the digital channelizer that employ the proposed structure are reduced when compared to FRM and traditional IFIR based digital channelizer. An example is used to illustrate the effectiveness of the proposed design. Results reveal that the proposed structure has a lower multiplier complexity than existing techniques. The proposed structure once implemented effectively, the power dissipation and hardware complexity are reduced. With the help of CSD, MOABC, and SIDC-CSE optimization, the filters used in this structure are made multiplier-less. Hence this structure is adaptable for the digital channelizer in the transponder of the satellite communication systems. 2023 Elsevier GmbH
