Published: April 2023

AbstractDecarbonizing 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.

AbstractFiber 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

AbstractThe 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.

Published: April 2023

AbstractDevelopment of a fluorescent probe for activity‐based sensing of activity of alcohol dehydrogenase, a key enzyme in ethanol biooxidation, is reported. A caged coumarin reporter is released upon the selective oxidation by the enzyme with a strong, >60‐fold emission enhancement. The probe has a low cytotoxicity and has been applied in visualising alcohol dehydrogenase activity in HepG2, A549 and HEK293T cells, demonstrating its potential as a convenient, easy‐to‐use bioanalytical tools in unveiling the roles of the enzyme in alcohol metabolism.
All that glitters is not gold: The application of psychoanalytic principles to community mental health
Authors: Rosenberg Larry M. , Boulanger Ghislaine 
Published: April 2023

AbstractThis 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

SummaryWith 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

AbstractTo 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.

AbstractIn 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

AbstractBulk 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

AbstractIn 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.
Quantitation of Mycophenolic Acid and Mycophenolic Acid Glucuronide in Serum or Plasma by LC‐MS/MS
Authors: Garg Uttam , Munar Ada , Frazee Clinton 
Published: April 2023

AbstractMycophenolic 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.Basic Protocol: Quantitation of mycophenolic acid and mycophenolic acid glucuronide in serum or plasma by LC‐MS/MS
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

SummaryIn 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

AbstractIon 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

AbstractThe 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.

Published: April 2023

AbstractHouseholds 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.
Implementation of a multiverse approach in developmental research: The longitudinal relation between self‐esteem and peer victimization

Published: April 2023

AbstractResearch 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.

Published: April 2023

AbstractThe 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.
Interfacial Phenomena as Related to Oil Recovery Mechanisms
Authors: Melrose J. C. 
Published: April 2023

Thermodynamic and hydrostatic principles are applied to commingled immiscible fluid phases occupying the interstices of a porous solid. Particular attention is given to the conditions of hydrostatic equilibrium for systems which include both fluid‐fluid interfacial and three‐phase contact line regions. The configurational stability of fluid interfaces is also examined. Some model pore systems are considered, and estimates obtained for the magnitude of the hysteresis in capillary pressure in such cases. These considerations define the role of interfacial phenomena in determining the extent to which a non‐wetting fluid can be displaced from a porous solid.On applique des principes de thermodynamique et d'hydrostatique aux phases de fluides non‐miscibles qui occupent ensemble les interstices d'un solide poreux. On prête une attention particulière aux conditions d'équilibre hydrostatique dans le cas de systèmes qui comprennent à la fois des zones interfaciales pour deux fluides et des régions de ligne de contact pour trois phases. On examine aussi la stabilité structurales des interfaces des fluides. On considère certains modèles de systèmes pourcux et obtient dans ces cas des estimés sur l'ampleur de l'hystérèse en pression capillaire. Les considérations précitées permettent de définir le rôle des phénomènes interfaciaux en déterminant jusqu'à quel point on peut déplacer un fluide non‐mouillant d'un solide poreux.

Published: April 2023

A conceptual process is described, based on laboratory data, for converting cellulosic feed to liquid and gaseous fuels by catalytic hydrogenation. In a preliminary economic analysis, major cost centers are identified common to hydroprocessing of all similar solid fuels. The process would be economically attractive only if the price of crude oil rises more rapidly than inflation.On décrit un procédé conceptuel basé sur des résultats d'expériences de laboratoire pour transformer, par hydrogénation catalytique, un produit cellulosique en combustibles liquides et gazeux. Dans une analyse économique préliminaire, on identifie les coûts principaux similaires à ceux de l'hydro‐traitement de tous les combustibles solides semblables. Ce procédé ne serait attrayant au point de vue économique que si le prix de l'huile brute s'élevait plus rapidement que l'inflation.
