Authors: Yadav Ashok , Singh Pramod , Verma Ramesh Kumar , Singh Vinod Kumar 
Published: November 2022

SummaryIn this paper, a slotted printed rectangular monopole antenna (SPRMA) is proposed that covers the entire UWB (ultra‐wideband) except for WiMAX and WLAN (802.11/a‐n). In the first stage, a rectangular monopole antenna is designed, which covers the entire UWB frequency. Then, a T‐slot is inserted in the radiating patch to have the rejection of the band containing WiMAX and WLAN (802.11/a‐n). The notch characteristics of the proposed antenna are observed from 3.0 to 3.65 GHz and 4.5 to 6.65 GHz respectively. Measured peak gain of 3.28 dBi has been observed at 4.25 GHz frequency. To show the validation of antenna, mathematical analysis using circuit theory has been also given in the paper. The prototype has been also tested inside the anechoic chamber to give the validation in real‐time environment. Several other reported antenna structures have also the same notch band in UWB with different notching methods. The proposed structure's radiation properties are compared with other reported structures proving the compactness of the proposed structure.

The impact of input data resolution on neural network forecasting models for wind and photovoltaic energy generation using time series data
Authors: AlShafeey Mutaz , Csaki Csaba 
Published: November 2022

AbstractAccurate photovoltaic (PV) and wind energy forecasting are crucial for grid stability and energy security. There are various modeling techniques and methods to design forecasting models, each leading to different accuracy. In this research, datasets were collected from a 546 kWp grid‐connected PV farm and a 2 MW wind turbine for one full year. These data were used to train and test artificial neural network models to forecast day‐ahead PV and wind energy utilizing time‐series input data with 15‐, 30‐, and 60‐min resolutions. The models were able to forecast the PV energy accurately, while the same models trained for wind showed poor performance. Higher input data resolutions lead to slightly better forecasting performance for the PV farm. Utilizing data with higher resolution can improve the forecast by 1%–5%. While for wind energy forecasting, the resolution has very minor effects, although the 30‐min resolution shows a slightly better forecasting performance.

Published: November 2022

AbstractZinc oxide, as a commonly used photocatalytic degradation of organic pollutants, typically shows limitations in wastewater treatment, such as aggregation and recycling problems caused by nanoscale dimensions and inappropriate substrates. Anchoring ZnO on substrates is a strategy to obtain stable catalytic performance. Particularly, natural fibers with hollow structures are an attractive alternative for ecological and economical ZnO loading templates, but depositing ZnO onto hollowed fiber surfaces presents a challenge. Here, a straightforward in situ growth method for producing nanostructured zinc oxide on cotton fibers from recycled garments is reported. The modified polydopamine on the fiber surface captures the catalyst required for in situ growth of ZnO and serves as a platform for spontaneous catalytic crystal growth on the fiber surface. The ZnO nanocrystals are uniformly dispersed on the outer and inner walls of cotton fibers, demonstrating excellent durability in wastewater treatments. Moreover, the photocatalytic performance of functional fibers is optimized by doping Ag nanoparticles to improve degradation efficiency. This can extend the prospect of further applications of developed ZnO/fibers in optoelectronics, spintronics, and provide inspiration for recycling and upgrading of used garments.

AbstractBackgroundRecognizing the causes of stillbirths and their associated conditions is essential to reduce its occurrence.ObjectiveTo describe information on stillbirths in Brazil during the past decade.Search strategyA literature search was performed from January 2010 to December 2020.Selection criteriaOriginal observational studies and clinical trials.Data collection and analysisData were manually extracted to a spreadsheet and descriptive analysis was performed.ResultsA total of 55 studies were included; 40 studies (72.2%) used the official data stored by national public health systems. Most articles aimed to estimate the rate and trends of stillbirth (60%) or their causes (55.4%). Among the 16 articles addressing the causes of death, 10 (62.5%) used the International Classification of Diseases; most of the articles only specified the main cause of death. Intrauterine hypoxia was the main cause reported (ranging from 14.3% to 54.9%).ConclusionHaving a national system based on compulsory notification of stillbirths may not be sufficient to provide quality information on occurrence and, especially, causes of death. Further improvements of the attribution and registration of causes of deaths and the implementation of educational actions for improving reporting systems are advisable. Finally, expanding the investigation of contributing factors associated with stillbirths would create an opportunity for further development of prevention strategies in low‐ and middle‐income countries such as Brazil.

AbstractThis study aimed to investigate the appropriate size of scaffold implantation on stress distribution and evaluate its mechanical and biomechanical properties considering hydrolysis. The meniscus acts as a load distribution in the knee, and its biomechanical properties are essential for the development of the PGA scaffold. We established a novel meniscal scaffold, which consists of polyglycolic acid (PGA) covered with L‐lactide‐ε‐caprolactone copolymer (P[LA/CL]). After 4 weeks of hydrolysis, the scaffold had a 7% volume reduction compared to the initial volume. In biomechanical tests, the implantation of scaffolds 20% larger than the circumferential and vertical defect size results in greater contact stress than the intact meniscus. In the mechanical evaluation associated with the decomposition behavior, the strength decreased after 4 weeks of hydrolysis. Meanwhile, in the biomechanical test considering hydrolysis, contact stress and area equivalent to intact were obtained after 4 weeks of hydrolysis. In conclusion, the implantation of the PGA scaffold might be a useful alternative to partial meniscectomy in terms of mechanical properties, and the PGA scaffold should be implanted up to 20% of the defect size.

Published: November 2022

AbstractBACKGROUNDThe synthesis of 2‐phenylquinazolin‐4(3H)‐ones has been studied extensively, yet previous synthetic routes involved unrecyclable catalysts, toxic organic solvents and an expensive purification step with column chromatography. The current study reports on the preparation of 2‐phenylquinazolin‐4(3H)‐ones from recyclable Brønsted acidic ionic liquid grafted onto silica.RESULTS1‐Methyl‐1‐(4‐sulfobutyl)pyrrolidinium hydrogen sulfate supported onto silica gel (MSPHS@SiO2) was prepared via a simple process. This material was demonstrated as an effective recyclable catalyst for the preparation of 2‐phenylquinazolin‐4(3H)‐ones through the cyclization of 2‐aminobenzamide and aldehydes. The optimized conditions were MSPHS@SiO2 (30 mol%), TBHP (2 mmol), EtOH:H2O (15 mL, 1:2) at 120 °C for 24 h. A wide range of 2‐phenylquinazolin‐4(3H)‐ones were obtained in 34.2–92.5% yields via simple recrystallization. The catalyst could be recycled and a plausible mechanism is proposed.CONCLUSIONMSPHS@SiO2 is an efficient and recyclable heterogeneous catalyst for the synthesis of 2‐phenylquinazolin‐4(3H)‐ones from readily available and low‐cost starting materials. © 2022 Society of Chemical Industry (SCI).

Published: November 2022

AbstractAn unprecedented series of 2‐imino‐1,3‐thiazolidin‐4‐ones were designed by straightforward and dynamic technique via one‐pot three‐component reaction of isothiocyanatobenzene, primary amines, ethyl bromoacetate and/or phenacylbromide. Furthermore, we found that the reaction between 2‐imino‐1,3‐thiazolidin‐4‐one and arylidenemalononitrile using of C2H5ONa as catalyst gave the corresponding 3‐(2‐phenylethyl)‐5‐(4‐arylidene)‐2‐(phenyl imino)‐1,3‐thia‐zolidin‐4‐one instead of 5‐amino‐7‐aryl‐3‐(2‐phenylethyl)‐2‐(phenylimino)‐3,7‐dihydro‐2H‐6‐carbonitrile. The identical molecules were designed through other routes via the reaction of 2‐imino‐1,3‐thiazolidin‐4‐one with the corresponding aryl carbaldehyde.

Published: November 2022

BackgroundBalanced steady‐state free precession (bSSFP) is important in cardiac MRI but suffers from off‐resonance artifacts. The interpretation‐limiting artifacts in patients with cardiac implants remain an unsolved issue.PurposeTo develop an interleaved radial linear combination bSSFP (lcSSFP) method with partial dephasing (PD) for improved cardiac cine imaging when implanted cardiovascular devices are present.Study TypeProspective.Phantom and SubjectsFlow phantom adjacent to a pacemaker and 10 healthy volunteers (mean age ± standard deviation: 31.9 ± 2.9 years, 4 females) with a cardioverter‐defibrillator (ICD) positioned extracorporeally at the left chest in the prepectoral region.Field Strength/SequenceA 3‐T, 1) Cartesian bSSFP, 2) Cartesian gradient echo (GRE), 3) Cartesian lcSSFP, and 4) radial lcSSFP cine sequences.AssessmentFlow artifacts mitigation using PD was validated with phantom experiments. Undersampled radial lcSSFP with interleaving across phase‐cyclings and cardiac phases (RLC‐SSFP), combined with PD, was then employed for achieving improved quality of cine images from left ventricular short‐axis view. The image quality in the presence of cardiac devices was qualitatively assessed by three independent raters (1 = worst, 5 = best), regarding five criteria (banding artifacts, streak artifacts, flow artifacts, cavity visibility, and overall image quality).Statistical TestsWilcoxon rank‐sum test for the five criteria between Cartesian bSSFP cine and RLC‐SSFP with PD. Fleiss kappa test for inter‐reader agreement. A P value < 0.05 was considered statistically significant.ResultsBased on simulations and phantom experiments, 60 projections per phase cycling and 1/6 PD were chosen. The in vivo experiments demonstrated significantly reduced banding artifacts (4.8 ± 0.4 vs. 2.7 ± 0.7), fewer streak artifacts (3.7 ± 0.6 vs. 2.6 ± 0.7) and flow artifacts (4.4 ± 0.4 vs. 3.7 ± 0.6), therefore improved cavity visibility (4.1 ± 0.4 vs. 2.9 ± 0.9) and overall quality (4.0 ± 0.4 vs. 2.7 ± 0.7).Data ConclusionRLC‐SSFP method with PD may improve cine image quality in subjects with cardiac devices.Evidence Level2.Technical EfficacyStage 1.
Activity data on crop management define uncertainty of CH4 and N2O emission estimates from rice: A case study of Vietnam

Published: November 2022

AbstractBackgroundGlobally, rice systems are a major source of atmospheric CH4 and for major rice‐producing countries, such as Vietnam, CH4 as well as N2O emissions from agricultural land used for rice production may represent about one‐fourth of total national anthropogenic greenhouse gas (GHG) emissions. However, national‐scale estimates of GHG emissions from rice systems are uncertain with regard to its magnitude, spatial distribution, and seasonality.AimsHere, we used the biogeochemical model LandscapeDNDC to calculate emissions of CH4 and N2O from rice systems in Vietnam (Tier 3 IPCC approach). Our objectives were to identify hotspot regions of emissions and to assess the contribution of N2O to the total non‐CO2 (CH4+N2O) GHG balance of rice systems as well as the seasonal and interannual variability of fluxes in dependence of uncertain input data on field management .MethodsThe biogeochemical model LandscapeDNDC model was linked to publicly available information on climate, soils, and land management (fertilization, irrigation, crop rotation) for calculating a national inventory in daily time steps of CH4 and N2O emissions from rice systems at a spatial resolution of 0.083° × 0.083°. Uncertainty in management practices related to fertilization, use of harvest residues or irrigation water, and its effects on simulated CH4 and N2O fluxes was accounted for by Latin Hypercube Sampling of probability distribution functions.ResultsOur study shows that CH4 and N2O fluxes from rice systems in Vietnam are highly seasonal, with national CH4 and N2O emissions totaling to about 2600 Gg CH4 year–1 and 42 Gg N2O year–1, respectively. Highest emissions were simulated for double and triple rice cropping systems in the Mekong Delta region. Yield‐scaled emissions varied largely in a range of 300–3000 kg CO2‐eq Mg–1 year–1, with CH4 emissions during the rice season(s) dominating (>82%) the total annual non‐CO2 GHG balance of rice systems. In our study, uncertainty in field management information (nitrogen fertilization, ratio synthetic to organic fertilization, residue management, availability of irrigation water) were major drivers of uncertainty of the national CH4 and N2O emission inventory.ConclusionsOur study shows that Tier 3 approaches, that is, process‐oriented model approaches combined with GIS databases, for estimating national‐scale GHG emissions from rice systems are ready to be applied at national scale. Generally, this approach is powerful as it allows to identify regions with elevated emissions, thereby accounting not only for CH4, but as well for N2O emissions. However, our study also shows that specifically better information on land management is required to narrowing uncertainties.

AbstractBACKGROUNDProbiotics are regarded as a promising strategy for relieving colitis caused by dextran sulfate sodium (DSS). One of the dominant probiotic fungi in Fuzhuan brick tea is identified as Aspergillus cristatus, but whether it can effectively improve colitis remains poorly understood. Here, the improving effect of A. cristatus on colitis was investigated.RESULTSOur results showed that A. cristatus intervention prominently alleviated gut damage as evidenced by the inhibition of shortened colon length, goblet cell depletion, and histological injury. Mechanistically, after administration with low concentrations of A. cristatus H‐1 and A. cristatus S‐6, the expression of interleukin‐6, tumor necrosis factor‐α, interleukin‐1β, nitric oxide, and malondialdehyde were significantly downregulated, and the content of glutathione, catalase, interleukin‐10, immunoglobulin G, claudin‐1, occludin, and zonula occludens‐1 were effectively upregulated. More importantly, live A. cristatus supplementation lightened DSS‐induced gut barrier damage by suppressing activation of the mitogen‐activated protein kinase (MAPK) signaling pathway, increasing the synthesis of short‐chain fatty acids (SCFAs) and stimulating the increase in peroxisome proliferator‐activated receptor γ expression.CONCLUSIONTogether, A. cristatus can attenuate DSS‐induced intestinal barrier damage through reducing the oxidative stress, regulating SCFA and inhibiting MAPK signaling pathways (P38/JNK/ERK). Our findings indicate that A. cristatus replenishment has potential as a new probiotic fungi to reduce DSS‐induced colitis. © 2022 Society of Chemical Industry.

Authors: Gisinger Daria , Kube René , Klapper Helmuth Sarmiento 
Published: November 2022

AbstractThe feasibility of additive manufacturing (AM) to produce industrial components, also for the oil and gas industry, has been demonstrated in the past. Therefore, current research efforts focus on demonstrating the reliability of AM materials subjected to demanding service conditions. In this regard, special attention has been paid to its corrosion resistance in harsh environments as one of the most critical properties in these applications. The beneficial combination of high strength, excellent thermal stability, and outstanding corrosion resistance makes alloy 718 (UNS N07718) the most used wrought and AM nickel alloy in the oil and gas industry. Wrought 718 has an extensive record of field performance in demanding oil and gas applications including directional drilling tools that undergo extreme mechanical loads in corrosive drilling fluids. On the other hand, limited data regarding the corrosion behavior of AM718 in typical drilling environments has been collected so far. In this research work, the pitting susceptibility of selective laser melted alloy 718 in simulated drilling environments has been studied. Open circuit potential measurements as well as cyclic potentiodynamic and potentiostatic polarization tests were used to characterize the pitting corrosion resistance of AM718 in alkaline brines at elevated temperatures. In addition, microstructural particularities in alloy 718 were investigated to explain the observed differences in the electrochemical behaviors.

Authors: Harel Meir , Eisenstadt‐Matalon Erella , Moshaiov Amiram 
Published: November 2022

AbstractSolving non‐cooperative zero‐sum multi‐objective Games (zsMOGs), under undecided objective preferences results, for each of the players, in a Set of Rationalizable Strategies (SRS) to choose from. First, this paper deals with finding for each of the players a preferred subset of such rationalizable strategies based on a‐priori incorporation of partial preferences of the decision‐makers using secondary criteria. The obtained subset is termed the Set of Preferred Strategies (SPS). Here, a novel archive‐based co‐evolutionary algorithm is suggested to search for the SPS for each of the players. An academic example is suggested to demonstrate and validate the algorithm. It concerns a zsMOG that involves two adversarial planar manipulators. Based on a theorem that is proven here, a theoretic reference SRS is found for each of the players. This reference SRS is applied to find a reference SPS, which is used for validating the algorithm. Next, a comparison study is performed between the proposed archive‐based co‐evolutionary algorithm and an elite‐based version of this algorithm. The results clearly show that the archive‐based algorithm is superior to the elite‐based version, yielding results that correspond well to the theoretic sets.

Published: November 2022

AbstractConsidering the financial coordination and investment cost sharing between the members, this paper studies the conformance quality improvement, carbon reduction, and green marketing optimal decisions of a green supply chain composed of one manufacturer and multiple retailers. The retailer is either cash‐strapped, cash‐rich, or both. By using the Stackelberg game method, we obtain the equilibrium results of the game in the three cases. The results show that financial coordination should be implemented between the manufacturer and the three types of retailers. However, only with the second type of retailer can cost‐sharing increase the profitability of both sides.
