Authors: ghamri Seyyed mortaza , khavari fatemeh , mollaee hassan 
Published: December 2022

Abstract
In this paper, a Lyapunov-based model reference ProportionalIntegrated-Derivative(PID) is designed using this approach for a DC\DC Buck
converter. However, under a wider range of disturbances, the PID strategy is not suitable for practical applications, and the parameters must be tuned again
for more reliable operations. To this end, a Lyapunov deﬁnition-based adaptivemechanism is adopted for the PID strategy, which can increase the stabilityand robustness of this scheme under various disturbances. Moreover, the system is considered a black-box without the need for accurate mathematical
modeling of the system that can result in a lower computational burden as
well as ease of implementation. The Lyapunov concept is a modern adaptive
algorithm that can ﬁnd optimal answers in shorter periods with more accuracy
and reliable stability insurance. To examine the strength of this method,
conventional Fractional-order PID (FOPID) and PID control techniques are
also tested to be compared with this work using the PSO algorithm to
tune their parameters. Finally, the results related to both simulations and
experimental outputs are tested, showing faster dynamics and signiﬁcant
robustness of Lyapunov-based PID strategy in diﬀerent challenging scenarios.

Abstract
Ecological disruptions and loss of productivity are foreseeable dangers facing Lake Abaya and the surrounding wetland. This in turn affected communities whose livelihood depends for fish and other Lake resources. The aim of the present study was to produce bioethanol from Water hyacinth (Eichhornia crassipes) as an alternative energy feedstock for a win-win eco-sanitation approach to halt ecological disruption. The Water hyacinth sample was collected from Lake Abaya in Arba Minch and pretreated to get rid of mud and dirty wash debris. DNS method was used for estimating Reducing sugars in the sample using DNS (3, 5- Dinitrosalicyclic acid) reagent. Bioethanol was obtained by fermentation of hydrolyzed substrates using Saccharomyces cerevisiae and was analyzed using qualitatively (Dichromate and FTIR methods) and quantitatively (Spectroscopic and Specific gravity methods). Our results indicated that Higher reducing sugar production efficiency (671.00 ± 3.00) was observed at 6% H2SO4 concentration on 10g biomass load. Lowest reducing sugar was recorded after hydrolysis of 5g biomass in 4% sulfuric acid. A promising alcoholic content (95 % v/v) and the existence of bioethanol by a combustion test shows Water hyacinth are also good sources of bioethanol. Generally, the FTIR spectroscopic investigation Conclude the product obtained from Water Hyacinth (Eichhornia crassipes) through acid hydrolysis, fermentation, and distillation was ethyl alcohol

Published: December 2022

Abstract
Model predictive direct power control (MPDPC) strategy offers numerous benefits over the traditional control strategies in active power filters (APF). However, the real-time execution duration (RTED) reduction of model predictive control in multilevel inverters is a big challenge. In this paper, an improved low-computation model predictive direct power control strategy for three-level four-leg APF (TL-FL-APF) is presented. First, based on generalized instantaneous reactive power theory, a new predictive power model for TL-FL-APF is established. Then, in order to reduce the RTED, classical multiple power predictions are converted into single voltage prediction through the principle of deadbeat control, and the optimized vector range is reduced from 81 to 4–18 by the method of spatial stratification using the γ-component of reference voltage vector. Finally, simulation and experimental results demonstrate that proposed low-computation MPDPC has excellent performance.

Abstract
Our previous studies have shown that hypoxia-inducible factor-1α (HIF-1α) has a protective effect on intestinal mucosal injury in septic rats, but the specific mechanism still needs to be clarified. In this study, we explored the protective effect of HIF-1α on intestinal mucosa in vitro and its molecular mechanism. Caco-2 cells were selected and experiment was divided into 2 parts. Part I: HIF-1α activator (DMOG) and inhibitor (BAY 87-2243) were used to treat LPS-stimulated Caco-2 cells respectively, to explore the effect of HIF-1α on LPS induced Caco-2 cell barrier injury; Part II: mTOR inhibitor (rapamycin), activator (MHY1485) combined with or without HIF-1α activator, inhibitor to treat LPS-stimulated Caco-2 cells respectively, and then the molecular mechanism of HIF-1α reducing LPS induced Caco-2 cell barrier damage was detected. The transmembrane resistance was measured by ERS-2 resistance meter, the permeation of fluorescein-labeled dextran (FD4) was measured by fluorescence method, and the protein levels of HIF-1α, Zona occludens 1 (ZO-1), occludin, claudin-1, p-mTOR and p-P70S6K were determined by Western blot. LPS induced Caco-2 cell injury, with decreased transepithelial electrical resistance (TEER) and increased FD-4 concentration. DMOG increased the TEER value, decreased the FD-4 concentration, and upregulated HIF-1α and tight junction (TJ) expression (P < 0.05) in Caco-2 cells, while BAY 87-2243 had the opposite effects. Rapamycin reduced the TEER, increased the FD-4 concentration, and downregulated the expression of p-mTOR, p-P70S6K, HIF-1α and TJs in Caco-2 cells (P < 0.05). MHY1487 increased the TEER, decreased the FD-4 concentration, and upregulated the expression levels of p-mTOR and p-P70S6K in Caco-2 cells (P < 0.05), while the expression levels of HIF-1α and TJs remained unchanged. Adding DMOG attenuated the effect caused by rapamycin, while adding BAY 87-2243 attenuated the effect caused by MHY1487. The results suggest that HIF-1α attenuate LPS-induced barrier injury in Caco-2 cells via regulation of the mTOR/P70S6K signalling pathway.

Published: December 2022

Abstract
Influenza A viruses cause respiratory infections that range from asymptomatic to deadly in humans. Non-human primates (NHPs) are susceptible to infection with a number of influenza A isolates, including viruses of the H3N2, H5N1 and H1N1 subtypes. A 9-year-old emperor tamarin (Saguinus imperator 0.1) presented acute respiratory distress and apathy. The animal died 24 hours after first clinical signs. A necropsy was performed and showed severe pulmonary congestion associated with thoracic and abdominal effusion. Bacterial and parasitological testing on different organ was negative. Unfortunately, no histological analysis was performed. However, a PCR analysis on lungs showed the presence of H5N3 virus. All the callitrichids that lived with this emperor tamarin (Saguinus imperator 0.1) : three emperor tamarins (Saguinus imperator 0.3) and three pygmy marmosets (Cebuella pygmaea 3.0) were sampled. Anti-Influenza A antibodies were found in all three emperor tamarins (Saguinus imperator 0.3) but not in the three pygmy marmosets (Cebuella pygmaea 3.0). All sera were negative for SARS-COV-2 analysis. The three emperor tamarins (Saguinus imperator 0.3) remained asymptomatic, and no treatment was given to them. All avian species in the zoo are vaccinated against influenza and no birds showed respiratory signs. An epidemiological survey is in progress to determine how the infection occurred. This condition has, to the best of our knowledge, not been reported in the literature.
Improvement of the electrical performance of Ag/MEH-PPV/SiNWs Schottky diode by the insertion of a thin layer of MEH-PPV polymer and study of the annealing effect

Abstract
Poly[2-methoxy-5-(2’-ethylhexyloxy)-1,4-phenylene vinylene] (MEH-PPV) thin layer was deposited on silicon nanowires (SiNWs) by electroless dipping method. SiNWs were obtained using Ag-assisted chemical etching process. Scanning Electron Microscopy (SEM) images reveal a vertical alignment of the SiNWs as well as the formation of MEH-PPV layer on their surfaces. The presence of MEH-PPV polymer on the SiNWs surface was confirmed by Energy-dispersive X-ray (EDX). Current-Voltage (I-V) measurements were performed for the electrical characterization of Ag/MEH-PPV/SiNWs diodes before and after annealing. The ideality factor (n), the barrier height (φb) and the series resistance (RS) are determined using the Cheung method. The diode parameters are strongly affected by the immersion duration in MEH-PPV solution as well as the annealing temperature. The rectification rate of the diodes was increased by MEH-PPV deposition. The annealing temperature has a great influence on the diode parameters by the thermal activation of carriers at Ag/MEH-PPV and MEH-PPV/SiNWs interfaces. I-V characteristics show an ohmic character for temperatures above 250° C. The electrical parameters such as equivalent carrier concentration (ND) and built-in voltage (Vb) and other values of φb are calculated from Capacitance-Voltage (C-V) measurements.

Published: December 2022

Abstract
We retrospectively evaluate the actual anterior-posterior (AP) corneal radius ratio in eyes with previous laser correction for myopia (M-LVC) according to axial length (AL) using biometry data exported from swept-source optical coherence tomography between January 2018 and October 2021 in a tertiary hospital (1,018 eyes with a history of M-LVC and 19,841 control eyes). The AP ratio was significantly higher in the LVC group than in the control group. Further, it was significantly positively correlated with AL in the LVC group. We also investigated the impact of the AP ratio and AL on the absolute prediction error (APE) in 39 eyes that underwent cataract surgery after M-LVC. The APE was significantly lower in the Barrett True-K with total keratometry (Barrett True-TK) than in the Haigis-L formula on eyes with AL above 26 mm. In eyes with AL of 26–28 mm, the percentage of prediction error within ± 1 D for Barrett True-TK and Barrett True-K was significantly higher than that for Haigis-L. In conclusion, in eyes with previous M-LVC, AP ratio increases with AL. The Barrett True-K or Barrett True-TK formulas are recommended rather than Haigis-L formula in M-LVC eyes longer than 26 mm.

Published: December 2022

Abstract
This paper proposes an axial-radial flux hybrid excitation permanent magnet eddy current coupling (HE-PMEC), where the ferrite magnet is employed for producing the radial flux and the DC excitation current is adopted for producing the axial flux. Moreover, a shielding layer is developed to regulate the radial magnetic field. Its magnetic field distribution, electromagnetic performance, and temperature distribution are calculated based on the 3D finite element method (FEM). By adjusting the applied DC excitation current density and the insertion depth of the shielding layer, the variable current starting process, the variable current braking process, and the speed regulation characteristic of the proposed HE-PMEC are obtained. It can be seen that the starting process, braking process, and speed regulation ability of the HE-PMEC have been enhanced greatly. Furthermore, the copper ring shape of the HE-PMEC is optimized by using the proposed improved multilevel optimization method. It can be seen that the performance of the HE-PMEC can be improved by using the new optimized copper ring shape. Lastly, compared with the conventional PMECs, the proposed HE-PMEC has shown its superior electromagnetic performance.
Plant growth promoting microbes with antibiotic resistance; can that be used together
Authors: Lunavath Madhavi , Bhukya Bhima , Swamy Mahadeva 
Published: December 2022

Abstract
The antibiotic application reduces the microbial count of pathogenic microbes along with beneficial plant growth promoting bacteria (PGPB). This can be avoided if PGPB has antibiotic resistance. Thirty bacterial isolates were found from nutrient-rich alkaline soil, associated with phosphate and potassium solubilization and IAA production potential. Twelve isolates were shortlisted and the antibiotic sensitivity of the bacterial isolates was tested against eight antibiotics using the disc diffusion technique. Based on various physiological tests, compatibility and 16S rRNA sequence analysis, two PGPB Bacillus megaterium (M-08) and Bacillus aryabhattai (M-24) were identified. Both the isolates were positive for starch hydrolysis, catalase activity, acid and gas production, urease and gelatin liquefaction tests. Isolate (M-20) had the highest PSI of 6.0. M-26 had the highest KSI of 5.6. M-08 and M-24 were antagonistic against phytopathogenic R. solani. The present study indicated the presence of diverse P and K solubilising bacteria in the tomato rhizosphere, with IAA production potential and antibiotic resistance. These bacterial isolates can serve as potential plant growth promoters as they showed an increase in N, P and K uptake in the plant. The research tried to bring up a hypothesis of antibiotic selective plant growth promoters or biocontrol agents and their benefit in acclimatization and establishment in soil despite the microbicidal applications. This method can be used worldwide, to eradicate phytopathogens, while leaving the beneficial PGP microbes in rhizospheres.
A comparison of multi-criteria decision making techniques for prioritizing flood potential based on morphometric parameter analysis

Published: December 2022

AbstractOne of the most important aspects of basin management is the prioritization of sub-basins. The flood potential of Kan sub-basins in Iran is prioritized in this study using morphometric parameters combined with model statistical correlation and multi-criteria decision-making systems. The Kan basin was studied using 17 morphometric parameters such as slope, elevation, curvature, ruggedness number, elongation coefficient, circularity coefficient, equivalent rectangle, drainage density, stream length, infiltration factor, time of concentration, duration-intensity of rainfall, land cover, land use, geology, bifurcation ratio, and length of overland flow. The relationship between parameters and weighting results revealed that climate and morphotopography (slope, elevation, curvature, and ruggedness number) were important factors in AHP flooding. Slope and time of concentration (0.11) duration-intensity of rainfall (0.12) have become one of the most critical factors in flooding in the ANP method. The Shannon entropy method identified stream length (0.15), elevation (0.11), and geology (0.11) as important flooding factors. Ranking in the AHP method revealed that the sub-basins of Imamzadeh Davood, Talun, and Doab had the highest score (0.74, 0.50, 0.41), and in the ANP method, the sub-basins of Imamzadeh Davood, Talun, and Sangan had the highest score (0.97, 0.51, 0.48). They were ranked first through third. Furthermore, Imamzadeh Davood, Talun, and Rendan rank first to third in Shannon entropy with points (0.97, 0.68, and 0.52). Other ranking methods, such as COPRAS, VIKOR, and TOPSIS, prioritized sub-basins. The TOPSIS method was deemed the best ranking method by Kendall and Spearman's correlation method. The results demonstrated that this model is highly accurate, and that morphometric sub-basins have a significant impact on flooding. Imamzadeh Davood and Sangan sub-basins are high-risk areas in this basin. There have been more floods in these areas. For validation, the HEC-HMS from the Natural Resources Organization's method was used. The HEC-HMS method yields results that are consistent with the Shannon entropy and ANP methods.

Published: December 2022

Abstract
Automatic segmentation solution is the process of detecting and extracting information to simplify the representation of Cardiac Magnetic Resonance images (CMRI) of Left Ventricle (LV) contour. This segmented information, using CMR images, helps to reduce the segmentation error between expert and automatic segmented contours. The error represents missing region values calculated in percentages after segmenting a cardiac LV contour. This review paper will discuss the major three segmentation approaches, namely manual approach, semi-automatic, and fully automatic, along with the segmentation models, namely image-based models, region-based models, edge-based models, deformable-based models, active shape-based models (ASM), active contour-based models (ACM), level set-based models (LSM), and Variational LSM (VLSM). The review deeply explains the performance of segmentation models using different techniques. Furthermore, the review compares 122 studies on segmentation model approaches, i.e., 16 from 2004 to 2010, 40 from 2011 to 2016, and 63 from 2017 to 2021, and 3 other related studies were conducted LV contour segmentation, cardiac function, area-at-risk (AAR) identification, scar tissue classification, oedema tissue classification, and identification via presence, size, and location. Given the large number of articles on CMR-LV images that have been published, this review conducted a critical analysis and found a gap for researchers in the areas of LV localization, LV contour segmentation, cardiac function, and oedoema tissue classification and segmentation. Regarding critical analysis, this paper summrised a research gap and made useful suggestions for new CMR-LV researchers. Although a timely reviewed study can lead to cardiac segmentation challenges, which will be discussed in each review section.

Authors: BORY Céline , BORY Olivier , GUELFUCCI Bruno , NICOLLAS Richard , Moreddu Eric 
Published: December 2022

Abstract
Purpose
The objective is to determine whether a medical treatment, the combination of cefotaxime and rifampicin, is effective in avoiding surgery for managing deep cervical abscesses in children and to determine prognostic factors in the efficacy of this medical treatment.
Methods
This is a retrospective analysis of all patients under 18 presenting with para- or retro-pharyngeal abscess over the period 2010–2020 in two hospitals' pediatric otorhinolaryngology departments. One hundred six records were included. Multivariate analyses were performed to study the relationship between the prescription of the Cefotaxime-rifampicin protocol at the onset of the management and the use of surgery and to evaluate the prognostic factors of its efficacy.
Results
The 53 patients who received the cefotaxime-rifampicin protocol as first-line treatment (vs. 53 patients receiving a different protocol) required surgery less frequently: 7.5% versus 32.1%, validated by a Kaplan-Meier survival curve and a Cox model analysis adjusted for age and abscess size (Hazard Ratio = 0.21). This good outcome of the cefotaxime-rifampicin protocol was not demonstrated when it was instituted as a second-line treatment after the failure of a different protocol. An abscess larger than 32 mm at hospitalization was significantly associated with more frequent use of surgery in multivariate analysis adjusted for age and sex (Hazard Ratio = 8.5).
Conclusions
The cefotaxime-rifampicin protocol appears to be an effective first-line treatment in managing non-complicated deep cervical abscesses in children.

Abstract
Purpose: Plasma Cell Dyscrasias are a heterogeneous group of hematological diseases.
The candidate ten genes identified from our transcriptome data are highly valuable and specific.
Methods: We investigated the prognostic biomarker status of these genes in Plasma Cell Dyscrasias. Expression levels of ISG20, EEF2, TRIB1, RRBP1, TMED9, KDELR1, DNAJC1, DPP7, COPE and LMAN2 genes were measured via qRT-PCR from bone marrow samples of 38 Multiple Myeloma, 23 MGUS and 16 control groups.
Results: According to our results, in the Multiple Myeloma group, all genes were more highly expressed than control and MGUS groups (p<0.05) In addition, the striking correlation with anemia factors, calcium and Durie Salmon Staging indicates that DNAJC1 is an important risk factor for MM (p<0.05). TMED9 was another prominent gene that showed higher expression in Multiple Myeloma compared to other groups. Also, there was strong association between TMED9 gene expression and clinical parameters of urea, Ca, albumin, LDH, and IGA levels (p<0.05) Moreover, TMED9gene in our results sheds light on myeloma genesis.
Conclusion: This study contributed significantly to the search on prognostic biomarkers for Multiple Myeloma progression from MGUS and for starting early treatment in MGUS.
