Authors: Zitte Leelee F. , Uzodinma Prisca I.
Published: April 2023

Indomethacin is a non-steroidal anti-inflammatory drug (NSAID) used mostly in the treatment of pain, feverish condition, headaches and inflammation. This study was therefore carried out to evaluate the effect of indomethacin on the male reproductive system, focusing on sperm quality. Twenty male rats were divided into four groups, (groups1,2,3,and 4) with group one serving as control. The other three groups receiving different doses of indomethacin, (groups 2-4 receiving 1mg/kg, 2mg/kg and 4mg/kg respectively) for 21 days. After the period, sperm samples were collected from all the groups and analyzed to evaluate sperm quality. The sperm qualities analyzed include; sperm motility, semen viscosity, sperm morphology, sperm count, etc. the results of the study indicated that indomethacin had a negative impact on the sperm qualities of the rats, as it decreased sperm count and sperm motility , and had a detrimental effect on the overall sperm quality. This study provides important insights into the potential side effects of indomethacin on male fertility. While its therapeutic benefits are well established, its impact on male fertility has not been documented. The findings of this study suggest that men who use indomethacin regularly may be at a higher risk of experiencing negative impacts on their reproductive health, including reduced sperm quality.

Authors: Sihombing Jumaini Andriana , Miqbel Muhammad , Sirait Batara Imanuel
Published: April 2023

Premature rupture of membranes (PROM) is the spontaneous rupture of the membranes before the onset of signs of labor. It can occur both before term (<37 weeks) and after term (> 37 weeks). Caesarean delivery is a surgical technique to deliver the fetus through an incision in the abdominal wall and uterine wall. This procedure is performed to minimize all complications from premature rupture of membranes. This study aims to determine the relationship between premature rupture of membranes and delivery of sectio caesarea at the UKI General Hospital in the 2019 period by using a descriptive content analysis method (analysis of medical records documents) with a cross-sectional approach and obtained 65 samples who experienced premature rupture of membranes. The results showed that 53 samples (81.55%) experienced premature rupture of membranes and performed sectio caesarea, while 12 samples (18.45%) had premature rupture of membranes but did not perform sectio caesarea with p-value = 0.001 (p <0.05) from the results of the chi-square statistical test. From the results of the analysis, it was found that there was a relationship between premature rupture of membranes and delivery of cesarean section at the UKI General Hospital for the 2019 period. It is suggested that patients avoid the factors that can cause premature rupture of the membranes, which have been told by the doctor or health worker and the patient's family to support the patient to remind them to avoid factors that can cause premature rupture of the membranes.

Genetic variability is major component which helps in selecting better genotypes under different environmental conditions, with this aim an experiment was conducted to understand the genetic potential, heritability, genetic advance and traits association of yield contributing characters for F6 and F7 families derived from the cross GKVK-6 × KCG-2 at the University of Agricultural Sciences, Bangalore in an augmented block design along with three checks viz., TMV-2, KCG-6 and KCG-2 during summer and Kharif 2017. Results from analysis of variance (ANOVA) revealed that highly significant differences were observed for all the characters studied. High genetic variability was observed for major yield contributing characters like the number of pods per plant (g), pod yield (g), kernel yield per plant (g), SMK% (sound mature kernel per cent), SCMR (SPAD chlorophyll meter reading) and SLA (specific leaf area) (cm2/g). Narrow difference between GCV (genotypic coefficient of variation) and PCV (phenotypic coefficient of variation) was observed for pods per plant, pod yield, SCMR and SLA and high heritability coupled with moderate genetic advance per cent mean was recorded for pod yield, SCMR and SLA indicating the involvement of additive gene action in controlling these traits. Three superior families were noticed with more pods plant-1, high pod yield plant-1, high kernel yield-1, high shelling (%), high SMK (%), high SCMR value, and low SLA value. Further, these superior families also revealed the presence of high parent offspring regression and intergeneration correlation, implying increased efficiency of selection for most of the traits considered and these were identified to be the important characters that could be used in selection for yield Keywords: GCV, PCV, Heritability, GAM, water use efficiency, Groundnut.

Published: April 2023

Erosion is the transport of parts of the soil from one place to another by natural agent, namely water, and wind. Mining in Indonesia generally uses open-pit mining methods. Generally, open pit mining has a very high erosion rate due to damage to soil aggregation and high interaction with rainwater. This study aims to determine the erosion rate and hazard class in the post-coal mining reclamation area. The research location was in the Jembayan Muarabara Group, Kutai Kartanegara Regency, East Kalimantan Province, from February 2021 to May 2021. The erosion rate measurement in this study used the stick method by measuring the erosion rate based on the change in soil surface loss in centimetres (cm) units. Erosion rate data collection is carried out periodically every month. The results showed that the highest erosion was in the Disposal area, namely 558.55 - 1341.94 tons/ha/year, including class V (very high), in the Stock Soil area with an erosion rate of 471.79 - 693.51 tons/ha/year including class IV (high) to class V (very high) and the lowest erosion rate in the reclamation area in 2019, namely 189.51 - 673.88 tons/ha/year including class IV (high) to class V (very high). Factors that affect the magnitude of the erosion rate are land cover vegetation, soil slope, and the soil's physical properties.

Published: April 2023

This study examined the growth and post-harvest quality of sod produced from C. aciculatus seed, a popular turfgrass in Ghana. Although viable and readily available, C. aciculatus seeds are not commonly used, and its sod quality characteristics are unknown. The experiment was conducted at the College of Agriculture Education, AAMUSTED, Mampong campus, using a 3 x 3 factorial experiment in a Randomized Complete Block Design with three replications, using a wooden frame system. The treatment factors were Fertilizer (10 t/ha chicken manure, 450 kg ha-1 Foliar fertilizer, and No fertilizer) and base netting (Rubber fiber net, Jute mat, and No net). Results showed that chicken manure with no base net and chicken manure with rubber fiber net interactions provided the earliest days to seedling emergence. Chicken manure and foliar-fertilized sods had significantly higher Clipping fresh and dry weights. Higher sod tensile strength, lasting, and handling quality were recorded with chicken manure and rubber fiber net interaction as the best performance in all instances. In conclusion, C. aciculatus seed can be used to produce high-quality sod, and it is recommended for commercial sod production in Ghana. Chicken manure and rubber fiber net interactions are the best treatments for achieving optimal results in C. aciculatus sod production.
A Research on Groundnut Shell Ash's Impact on Lateritic Soils' Soil Stabilization
Authors: Tochukwu Mmeka Paschal , Junior Abriku Alex
Published: April 2023

This study aims to provide information on the engineering characteristics of laterite soil, which is frequently used as a building material in civil engineering projects. The significance of subsoil investigations has grown significantly in light of the recent trend of civil construction collapses. In non-industrial nations like Nigeria, minimal residual soil has long been a problem for civil infrastructure, including buildings, culverts, dams, and highways. Also, there has been a lot of global research into using lateritic soil for engineering reasons due to the rising costs of conventional stabilizing agents and the need to utilize industrial and agricultural waste in cost- effective ways for engineering applications. As implied by the research project's topic, this is accomplished through a comprehensive field inquiry and intensive laboratory testing (the effect of groundnut shell ash on lateritic soil properties). The index property test categorized the soil into the A-2-4 subgroup in accordance with the AASHTO standard. As a result, the substance is deemed unfit for use as a foundation or sub-base for paving roads. Tests on the soil's index and geotechnical characteristics after adding groundnut shell ash show significant changes in the parameters. The tests performed for this study adhered to BS 1377:1975 standards. An analysis of the data shows that GSA can be used as a binding agent in the absence of cement, even if it does not have the same binding strength as cement. 4% G.S.A. was also discovered to be the optimal content concentration. All tests and analyses are shown in chapters three and four.
Application of Soil Structure Interaction on Building with Basement using Nonlinear Soil Springs
Authors: Jesica Anastasia , Pudjisuryadi Pamuda , Rosidi Dario
Published: April 2023

In a typical building design, the interaction between building and surrounding soils is often ignored. Since soil is deformable and has limited capacity to resist loads, this interaction, called soil-structure interaction (SSI), could alter building responses, especially during earthquake loadings for buildings with significant basement depths. In this study, a 10-story reinforced concrete building with 3-level basement was used to evaluate the effects of SSI on building during earthquakes. Dynamic time response analyses were performed using earthquake time histories scaled to a design response spectrum for a Surabaya, Indonesia, location. Soil responses during earthquakes were modeled using nonlinear hysteresis normal and elastic-perfectly plastic frictional soil springs, developed using the hardening soil with small strain stiffness model. Depth-varying ground motions were also applied along the basement depth. The results show inconclusive SSI effects, where some of the time histories produce greater base shears and inter-story drifts when SSI is considered, while others show the opposite results.
The Preliminary Study of Liquefaction Susceptibility Map in the Yogyakarta-Bawen Toll Road Sections I and II, Indonesia
Authors: Kevin Paulus , Muhrozi Muhrozi
Published: April 2023

The parts of Yogyakarta-Bawen Toll Road Indonesia, based on the geological agency’s liquefaction susceptibility map are located on moderately susceptible to liquefaction soil. This map can be a preliminary indication of liquefaction as it can roughly indicate liquefaction potential. However, it cannot illustrate the actual condition in detail as its inputs are macro parameters (geological and seismicity factors). The existence of silty sand and sand, earthquake sources, and shallow groundwater increase the liquefaction possibility to occur in this important national project. Therefore, the Liquefaction Severity Index (LSI) and the Liquefaction Potential Index (LPI) using Sonmez’s and Iwasaki’s analysis methods are conducted with peak ground acceleration (PGA) of 0.322 g for the first section and in the second section 0.298 g. The results of the three types of analysis have relatively similar trends but the differences are in each category. The LSI’s categories are very low-moderate in the observed location, meanwhile, the LPI’s categories are low-very high.

Published: April 2023

High-precision lasers and anti-aircraft radars are the main equipment to protect the Korean Peninsula, and require preemptive maintenance before signs of failure. Of the key components in the drive sector, bearings do not have a fault alarm function. Therefore, the technology for diagnosing defects in bearings before the performance degradation of equipment occurs is becoming more important. In this paper, for the experimental analysis, we measured the acceleration of the four sets of the same lot using acceleration sensors. Through periodic measurements, the factors that changed until the bearing stopped rotating were analyzed. To determine the replacement time, the main factors and threshold values of the bearing signal were analyzed. The error of the theoretical and experimental analysis results of the defect frequency was within 2.8 %, and the validity of the theoretical analysis results could be confirmed. Based on the results, it is possible to remotely transmit trouble alerts to users through the system check function.
Numerical Analysis on Dynamic Behavior Characteristics of an Amphibious Assault Vehicle during Water Entry
Authors: Heo Youngmin , Kim Taehyung
Published: April 2023

In the present study, the dynamic behavior characteristics of an amphibious assault vehicle during water entry were analyzed using STAR-CCM+, a commercial computational fluid dynamics(CFD) code. All computations were performed using an overset mesh system and a RANS based flow-solver coupled with dynamic fluid-body interaction(DFBI) solver for simulating three degrees of freedom motion. For numerical validation of the solver, a water entry simulation of inclined circular cylinder was conducted and it was compared between an existing experiment data and CFD results. The pitch angle variation and the trajectory of the circular cylinder during water entry shows good agreement with previous experimental and numerical studies. For the water entry simulations of the amphibious assault vehicle, the analysis of dynamic behaviors of the amphibious assault vehicle with different slope angles, submerged depths and initial velocities were conducted. It is confirmed that the steep slope angle increases the submerged volume of the amphibious assault vehicle, so the buoyancy acting on the vehicle is increased and the moved distance for the re-flotation is decreased. It is also revealed that the submerged volume is increased, bow-up phenomenon occur earlier.
Fragmentation shapes nest density and social structure but not genetic diversity of Temnothorax crassispinus (Formicidae)
Authors: Cordonnier Marion , Lindner Thomas , Heinze Jürgen
Published: April 2023

Human activities affect biodiversity by reducing the area of habitats, altering their shape, and increasing their isolation. Ants are particularly sensitive to habitat fragmentation, as it may locally change abiotic conditions, the availability of food and nest sites, the abundance of mutualists, competitors and predators, and also restrict gene flow between patches. As a result, the genetic population and colony structure of ants is expected to show signs of fragmentation. In the present study, we investigated the impact of fragmentation on the ant Temnothorax crassispinus in 45 forest patches across the Franconian Jura, Germany. Based on 283 colonies, of which 156 were genetically analyzed, we evidenced the presence of two putative distinct genetic clusters in the study area. Both the nest densities and the presence of queen were impacted by the number of adjacent forest patches within 400 m around the focal patch, but neither by patch shape nor patch size. We could not detect any effect of fragmentation on the genetic diversity, probably because the high dispersal abilities of T. crassispinus counterbalance any detrimental genetic consequences of fragmentation. Nevertheless, fragmentation still impacts the species density as well as the social structure of its colonies. Further investigations regarding the drivers of occurrence at a finer spatial scale might clarify the role of edge effects on the occurrence of this species.

Published: April 2023

This study investigates the relationship between dark personality traits, aggressive behavior in violent video games, and severe traffic violations among 200 driving offenders from Tehran, Iran, participating in a rehabilitation program. Participants engaged in a computerized shooting decision task, where their tendency to shoot unarmed targets (innocent victims), compared to armed targets (criminals), was used as an indicator of aggressive behavior toward innocent victims. Additionally, they completed self‐report measures of narcissism, Machiavellianism, psychopathy, and sadism to evaluate the impact of Dark Tetrad personality traits on their behavior. Bivariate analyses revealed associations between Dark Tetrad personality traits and aggressive behavior in the video game with serious traffic offenses. Multivariate analyses identified Machiavellianism, sadism, and aggressive behavior in video games as significant predictors of severe traffic offenses. The results suggest that dark personality traits and aggressive behavior in video games may aid in better identifying road traffic offenders with the most severe violations. Potential implications for preventing repeated traffic offenses by tailoring rehabilitation programs are discussed.

Published: April 2023

With the increasing demand of smart electronic textiles, fiber‐shaped sensing devices have rapidly attracted growing interests, in which elastic fiber sensors can monitor a wider range of strains without compromising their flexibility and adaptability with conventional textiles. However, it is still a major challenge to prepare highly sensitive and durable sensing fibers with multifunction. Herein, using a thermally drawn process, highly stretchable elastomeric fibers that are composited with copper particle‐mixed liquid metal electrodes to produce highly elastic piezoresistive strain sensor are fabricated. The composite liquid medal fiber sensor (LMFS) exhibits a strain at break up to 850% and a tensile stress of 6 MPa. When used as a tensile sensor, LMFS can detect large strain levels up to 400%. As a pressure sensor, LMFS can detect an object as light as 0.2 N. The composite fibers can be integrated into a fabric to monitor human motions and Morse code signals. In addition, the fibers can also be applied as an electric heater, the temperature quickly reaches 45 °C at 0.6 V in its original length and 29.3 °C at 0.6 A current with a 250% strain. This work exhibits excellent potential of multifunctional fiber devices in wearable sensing devices.
Liminality, COVID‐19 and the long crisis of young adults' employment

Published: April 2023

The COVID‐19 crisis has brought into sharp relief the precarious employment situation of young people, precipitating a raft of academic and public claims of an unprecedented crisis that has disrupted young lives. Our study contributes to research on youth labour and transitions with new longitudinal empirical analysis. Our analysis challenges the “newness” of the precarity highlighted by COVID‐19, focussing on employment. It draws on longitudinal mixed methods data from a research project tracking the transition to adulthood of young Australians. We make use of the concept of liminality to analyse the labour patterns for this group of young adults for the past 5 years. While we acknowledge the impact of COVID‐19 on young people's lives, our analysis reveals a precarisation of labour conditions for a significant proportion of participants that precedes the pandemic crisis. We conclude that the tendency in some youth research and in public discourse, to depict contemporary events as heralding “new” crises for young people, obscures the deeper structural arrangements that continually position the young to take the brunt of social and economic policies.

Published: April 2023

Individuals with more complex jobs experience better cognitive function in old age and a lower risk of dementia, yet complexity has multiple dimensions. Drawing on the Social Networks in Alzheimer Disease study, we examine the association between occupational complexity and cognition in a sample of older adults (N = 355). A standard deviation (SD) increase in complex work with people is associated with a 9% to 12% reduction in the probability of mild cognitive impairment or dementia, a 0.14–0.19 SD increase in episodic memory, and a 0.18–0.25 SD increase in brain reserve, defined as the gap (residual) between global cognitive function and magnetic resonance imaging (MRI) indicators of brain atrophy. In contrast, complexity with data or things is rarely associated with cognitive outcomes. We discuss the clinical and methodological implications of these findings, including the need to complement data‐centered activities (e.g., Sudoku puzzles) with person‐centered interventions that increase social complexity.

Published: April 2023

Decarbonizing the transportation sector is among the biggest challenges in the fight against climate change. CO2‐neutral fuels, such as those obtained from renewable methanol, have the potential to account for a large share of the solution, since these could be directly compatible with existing power trains. Although discovered in 1977, the zeolite‐catalyzed methanol‐to‐gasoline (MTG) process has hardly reached industrial maturity, among other reasons, because maximizing the production of gasoline range hydrocarbons from methanol has proved complicated. In this work, we apply multimodal operando UV/Vis diffuse reflectance spectroscopy coupled with an online mass spectrometer and “mobility‐dependent” solid‐state NMR spectroscopy to better understand the reaction mechanism over zeolites H‐Beta and Zn‐Beta. Significantly, the influential co‐catalytic role of oxymethylene species is linked to gasoline formation, which impacts the MTG process more than carbonylated species.

Published: April 2023

Fiber lithium‐ion batteries represent a promising power strategy for the rising wearable electronics. However, most fiber current collectors are solid with vastly increased weights of inactive materials and sluggish charge transport, thus resulting in low energy densities which have hindered the development of fiber lithium‐ion batteries in the past decade. Here, a braided fiber current collector with multiple channels was prepared by multi‐axial winding method to not only increase the mass fraction of active materials, but also to promote ion transport along fiber electrodes. In comparison to typical solid copper wires, the braided fiber current collector hosted 139 % graphite with only 1/3 mass. The fiber graphite anode with braided current collector delivered high specific capacity of 170 mAh g−1 based on the overall electrode weight, which was 2 times higher than that of its counterpart solid copper wire. The resulting fiber battery showed high energy density of 62 Wh kg−1.

Published: April 2023

The ethanol/water separation challenge highlights the adsorption capacity/selectivity trade‐off problem. We show that the target guest can serve as a gating component of the host to block the undesired guest, giving molecular sieving effect for the adsorbent possessing large pores. Two hydrophilic/water‐stable metal azolate frameworks were designed to compare the effects of gating and pore‐opening flexibility. Large amounts (up to 28.7 mmol g−1) of ethanol with fuel‐grade (99.5 %+) and even higher purities (99.9999 %+) can be produced in a single adsorption process from not only 95 : 5 but also 10 : 90 ethanol/water mixtures. More interestingly, the pore‐opening adsorbent possessing large pore apertures showed not only high water adsorption capacity but also exceptionally high water/ethanol selectivity characteristic of molecular sieving. Computational simulations demonstrated the critical role of guest‐anchoring aperture for the guest‐dominated gating process.

All that glitters is not gold: The application of psychoanalytic principles to community mental health
Authors: Rosenberg Larry M. , Boulanger Ghislaine
Published: April 2023

This special issue on community mental health focuses on the ways in which several innovative mental health programs across the United States have risen to the challenge of incorporating psychodynamic principles into their clinical practice. Contrasted with these domestic programs are reports from a number of countries in Europe, Latin America, and the Middle East in which local clinicians describe how community mental health programs in their countries are tackling these issues. In this introduction, we emphasize factors common to the populations these authors serve, the organizational challenges they face, and the successes they achieve by way of their skill, creativity, and perseverance. We underscore the ways in which they articulate how psychoanalytic thinking, training, and practices have evolved in response to lessons learned and changing political, economic and cultural climates. We conclude that applied psychoanalysis, and particularly psychoanalysis applied to community mental health has, in some ways, been at the forefront of change in psychoanalytic practice in general. The modifications made by those in community mental health are viewed as necessary accommodations for both the communities served and for the psychoanalytic enterprise itself.

Authors: Cretarola Alessandra , Figà‐Talamanca Gianna , Patacca Marco
Published: April 2023

With the availability of social networks, specialized forums, and online news, sentiment analysis has become a common and useful technique for the analysis of economic and financial scenarios. Several data‐providers have also started computing proprietary sentiment indexes on financial assets to be delivered together with market price and trading volume. We develop a modified version of the mean‐reverting 4/2 stochastic volatility model introduced in Escobar‐Anel & Gong (2020) to describe the dynamics of commodities. In our specification, jumps are allowed in the asset price dynamics, and the drift coefficient may also switch between regimes related to a sentiment indicator. In this framework, we discuss the distributional characteristics of asset returns, provide a numerical procedure for model estimation, and give some preliminary results on the pricing of European‐style derivatives. Finally, the model is fitted to the market data for Gold and Crude Oil.
EEG frequency tagging evidence of intact social interaction recognition in adults with autism
Authors: Oomen Danna , Cracco Emiel , Brass Marcel , Wiersema Jan R.
Published: April 2023

To explain the social difficulties in autism, many studies have been conducted on social stimuli processing. However, this research has mostly used basic social stimuli (e.g., eyes, faces, hands, single agent), not resembling the complexity of what we encounter in our daily social lives and what people with autism experience difficulties with. Third‐party social interactions are complex stimuli that we come across often and are also highly relevant for social functioning. Interestingly, the existing behavioral studies point to altered social interaction processing in autism. However, it is not clear whether this is due to altered recognition or altered interpretation of social interactions. Here, we specifically investigated the recognition of social interaction in adults with and without autism. More precisely, we measured neural responses to social scenes depicting either social interaction or not with an electroencephalogram frequency tagging task and compared these responses between adults with and without autism (N = 61). The results revealed an enhanced response to social scenes with interaction, replicating previous findings in a neurotypical sample. Crucially, this effect was found in both groups, with no difference between them. This suggests that social interaction recognition is not atypical in adults with autism. Taken together with the previous behavioral evidence, our study thus suggests that individuals with autism are able to recognize social interactions, but that they might not extract the same information from those interactions or that they might use the extracted information differently.

Published: April 2023

In the work, four new Sb‐based phosphates, K4(SbO2)5(PO4)3, Rb(SbO2)2PO4, Rb3(SbO2)3(PO4)2 and Cs3(SbO2)3(PO4)2(H2O)1.32, were successfully synthesized by a high‐temperature melt method. Among them, Rb(SbO2)2PO4 and Rb3(SbO2)3(PO4)2 are the first reported examples of Rb‐containing alkali metal Sb‐based phosphates. They show three‐dimensional (3D) frameworks composed of [Sb8P4O30]∞ layer for K4(SbO2)5(PO4)3 and [Sb6P2O20]∞ layer for Rb(SbO2)2PO4, and 2D lamellar structure composed of [Sb3P2O10]∞ for Rb3(SbO2)3(PO4)2 and Cs3(SbO2)3(PO4)2(H2O)1.32. A detailed structural comparison shows that the structure dimensions for them transfer from 1D to complex 3D framework with the increase of (Sb+P)/O ratio, which affects performances of the compounds. Optical property and energy band structure calculations were also carried out based on the density functional theory (DFT). The present study enriches the diversity of Sb‐based phosphates and paves the way for further explore their optical properties in the future.

Published: April 2023

Bulk chemical 2‐methyl‐2‐butene, one of the main C5 distillates of the petrochemical industry, has scarcely been utilized directly in synthesizing high‐value‐added fine chemicals. Herein, we use 2‐methyl‐2‐butene as the starting material to develop a palladium‐catalyzed highly site‐ and regio‐selective C‐3 dehydrogenation reverse prenylation of indoles. This synthetic method features mild reaction conditions, a broad substrate scope, atom‐ and step‐economies.

Published: April 2023

In this contribution, dynamic photoinduced wrinkle erasure enabled by photomechanical changes in supramolecular polymer‐azo complexes was characterized via confocal microscopy. Different photoactive molecules, disperse yellow 7 (DY7) and 4,4′‐dihydroxyazobenzene (DHAB), were compared to 4‐hydroxy‐4′‐dimethylaminoazobenzene (OH‐azo‐DMA). The characteristic erasure times of wrinkles were quickly assessed by using an image processing algorithm. The results confirm that the photoinduced movement on the topmost layer can be successfully transferred to the substrate. Furthermore, the chosen supramolecular strategy allows decoupling the effect of molecular weight of the polymer and photochemistry of the chromophore, allowing quantitative comparison of wrinkling erasure efficiency of different materials and providing a facile way to optimize the system for specific applications.

Authors: Garg Uttam , Munar Ada , Frazee Clinton
Published: April 2023

Mycophenolic acid (MPA) is an immunosuppressant that is used as an adjunct therapy in renal, liver, and heart transplantation. Due to its narrow therapeutic range, monitoring MPA levels is essential to avoid toxicity and organ rejection. Although immunoassays are available for the determination of MPA, mass spectrometry methods are preferred due to their higher specificity. Herein, we describe a liquid chromatography tandem mass spectrometry (LC‐MS/MS) method utilizing positive ionization electrospray and multiple reaction monitoring (MRM) for the quantification of MPA levels and its conjugate, MPA glucuronide (MPAG). Blood collected in a plain, EDTA, or heparin‐containing tube is centrifuged to separate the serum or plasma. Proteins are precipitated using a zinc sulfate solution and acetonitrile containing deuterated internal standards (MPA‐d3 and MPAG‐d3). The resulting protein‐free supernatant is injected into the LC‐MS/MS system for analysis. The chromatography involves the use of a C18 column and ammonium acetate/water/formic acid and ammonium acetate/methanol/formic acid mobile phases. Quantification of MPA and MPAG levels is achieved by comparing the MRM peak area ratios of analytes and internal standards, consisting of specific precursor/product pairs, with those of calibrators at various concentrations. Calibration curves are constructed from the MRM peak area ratios of calibrators and internal standards versus concentration. © 2023 Wiley Periodicals LLC.

PSO based universal phase shift modulation scheme for DAB converter to eliminate backflow power in energy storage applications
Authors: Bheemraj T. S. , Karthikeyan V. , S. Kumaravel
Published: April 2023

In battery energy storage system (BESS) applications, the life of the battery depends on the quality of the charging/discharging current. However, the dual active bridge (DAB) converter, which interfaces BESS with the DC link, suffers from a backflow current in all modulation schemes, degrading the battery's performance. Hence, this paper proposes a particle swarm optimization (PSO) based universal phase shift (UPS) modulation scheme to improve the battery's life. In the proposed modulation scheme, the phase shift ratio of DAB to eliminate the backflow power is estimated using PSO. Also, it is observed that there is an improvement in the zero voltage switching (ZVS) range of the DAB. Hence, the overall efficiency of the DAB converter is increased over a wide operating region. The operating principle of the proposed modulation scheme, steady state analysis of power transmission, and backflow power are reported in this paper. The theoretical performance of the proposed modulation scheme is validated in a 2 kW experimental setup.
Generation of an obliquely propagating shear alfven wave in dusty plasma by an ion beam
Authors: Gupta Rajesh , Gupta Ruby , Sharma Suresh C.
Published: April 2023

Ion beam‐dusty plasma interaction leads to significant changes in the dispersion relation of shear Alfven wave depending on the beam, dust grain, and plasma parameters. Hydrogen ion beam particles interact with the shear Alfven wave via cyclotron interaction when they counter‐propagate with the wave and they can also interact with the co‐propagating wave via Cerenkov interaction. The interaction causes beam as well as plasma density fluctuations and gives rise to perpendicular currents. We have analytically obtained the dispersion relation and the growth/damping rate expressions for obliquely propagating shear Alfven waves in dusty plasma. The effect of beam velocity, magnetic field, wave number, dust particle density, and dust charge fluctuations are discussed. It is shown that both the wave frequency and the maximum growth rate decrease with an increase in beam velocity and the variations are different for parallel and perpendicular wave numbers. The dust particles enhance the frequency and maximum growth rate while the dust charge fluctuations induce damping. The results are in good agreement with the experimental observations.
Effect of the ion drag force on head‐on collisions between two nonlinear dust acoustic waves in a strongly coupled dusty plasma

Published: April 2023

The effect of dust grain pressure on the head‐on collision of two dust‐acoustic solitary waves in non‐magnetized, collisionless, and strongly coupled dust plasma has been investigated [J. Plasma Phys. (2020), 86, 905,860,111]. In this paper, the model is augmented by incorporating the ion drag force on dust grains. By way of the extended perturbation method of Poincaré‐Lighthill‐Kuo, Korteweg‐de Vries equations are derived. The wave characteristics along with the phase shifts after the head‐on collision are analytically established and numerically assessed. It revealed a non‐negligible decrease in the wave amplitude and the phase shift.

Households with school‐aged children worldwide were affected by school closures caused by COVID‐19. Using a sociomaterial orientation and collective biography methodology, this study examined the household curricula of diverse families in Ontario, Canada with children in pre‐school through Grade 12. It found two distinct curricular phases to the pandemic, each with its own networked constituents, movements, and effects. Phase I involved learning at home during the lockdown in Spring and Summer 2020; Phase II involved online and face‐to‐face learning in the Fall of 2020. The constituents involved in curriculum making in Phase I were expansive and unexpected. Multiple timescales, modes, languages, and knowledge disciplines assembled to (re)configure households as learning spaces that produced novel opportunities for children's knowing, doing, and being. The makeup and movements of the Phase II assemblages were more of a return to the normalized boundaries of implemented school curricula that demarcated subject areas, languages, learning/play, learning/assessment, and body/mind. Concerned with questions of equity in/through curriculum, this study suggests a curriculum paradigm that foregrounds learners' and teachers' engagement with sociomaterial lifeworlds and their ethical relationship building with the more‐than‐human and the world.
Equity Levers: What Predicts Enrollment in and Number of College‐Level Courses Taken in High School?

Published: April 2023

This study explores the extent to which student, family, peer, and school factors predict (a) whether students take Advanced Placement® (AP®) courses, International Baccalaureate (IB) courses, and dual enrollment courses and (b) in models limited to course takers, how many courses they completed. Our findings, based on a nationally representative, longitudinal sample, suggest that, when it comes to college‐level high school course taking, the relative advantage of higher socioeconomic status (SES) is less for African American students than it is for White and Asian students. Ninth‐grade math skills are the strongest predictor of AP or IB and dual enrollment course taking, above and beyond demographic background characteristics like SES and race or ethnicity. High school girls take AP/IB and dual enrollment courses at a higher rate than boys, and they take more of these courses. The level of academic focus of students and their peers is associated with both AP or IB and dual enrollment course taking, whereas having parents focused on college preparation and course taking only predicts AP or IB course taking. School factors associated with AP or IB course taking include U.S. region and rural location; the percentage of math teachers with a master's degree is also positively associated with the number of AP or IB courses students take. These findings highlight the importance of equitable educational opportunities starting from a young age. They also indicate a need for increased early attention to student math skills and for more supports for parents and school staff to enable them to encourage and prepare all students, especially those from historically marginalized groups, to take college‐level courses in high school.
Implementation of a multiverse approach in developmental research: The longitudinal relation between self‐esteem and peer victimization

Published: April 2023

Research in social sciences has been questioned in the past decade due to the failure to replicate earlier work. To improve the trust in results, best practices that reduce data‐analytical flexibility have been proposed, such as preregistration. Another more recent such development regards the multiverse approach. The current study sought to demonstrate the benefits of applying the multiverse approach within developmental psychology. Using the relation between self‐esteem and peer victimization in adolescence as an example, we examined how both the concurrent as well as longitudinal association was impacted by data‐analytical decisions, such as the operationalization of variables, treatment of outliers, inclusion of covariates, and paths estimated in the model. Indeed, through the multiverse approach, we showed that and how these decisions matter for the model fit and estimates of the associations. We were thus able to illustrate that the multiverse approach increases transparency, makes it possible to examine the robustness of effects and can help advance theory building. Limitations of this approach as well as recommendations for other researchers are discussed.
Optimized lung cancer detection by amended whale optimizer and rough set theory
Authors: Chang Zuzheng , Rodriguez Dragan
Published: April 2023

The current paper proposes a new hierarchical procedure for efficient diagnosis of lung cancer computed tomography (CT) images. Here, after noise removal based on median filtering, a contrast enhancement based on general histogram equalization (GHE) has been utilized. Then, a modified version of K‐means clustering has been used for the area of interest segmentation in the CT images. The major characteristics of the segmented images have been selected during an optimization technique and the outputs are injected into an optimized radial basis function (RBF) network for the final classification. Optimization in the classification stage and feature selection is by an improved metaheuristic technique, called Amended Whale Optimization Algorithm was proposed. The designed method is then applied to “The RIDER Lung CT” database and its achievements are validated by several latest techniques to show its higher efficacy.
Identification of Submicroscopic Lymph Node Metastases in Patients With Malignant Melanoma

Published: April 2023

In order to detect micrometastatic disease, our laboratory has developed a method for evaluating lymph node sections from patients with stage 1 or 2 melanoma. Lymph nodes isolated from standard dissections are bivalved; one half is subjected to routine histopathological evaluation and the other half disrupted and placed into cell culture. The cultured cells are identified by cytologic examination, immunohistologic staining, and the presence of melanoma‐associated antigens. Lymph nodes (448) from 62 patients with malignant melanoma were evaluated by tissue culture. Fifteen patients were upgraded from stage 1 or 2 to stage 3 disease after micrometastases were identified in lymph node cultures. Recurrence of disease in histologically node negative patients, during a mean 24‐month follow‐up, has only been observed thus far in patients with culture positive lymph nodes. In addition, these results add evidence to the belief that missed micrometastatic disease in regional nodes is a sign of occult systemic metastases that would account for the defined recurrence rate in histologically node negative patients.
