Published: May 2024

Hardware‐based sensing frameworks such as cooperative fuel research engines are conventionally used to monitor research octane number (RON) in the petroleum refining industry. Machine learning techniques are employed to predict the RON of integrated naphtha reforming and isomerisation processes. A dynamic Aspen HYSYS model was used to generate data by introducing artificial uncertainties in the range of ±5% in process conditions, such as temperature, flow rates, etc. The generated data was used to train support vector machines (SVM), Gaussian process regression (GPR), artificial neural networks (ANN), regression trees (RT), and ensemble trees (ET). Hyperparameter tuning was performed to enhance the prediction capabilities of GPR, ANN, SVM, ET and RT models. Performance analysis of the models indicates that GPR, ANN, and SVM with R2 values of 0.99, 0.978, and 0.979 and RMSE values of 0.108, 0.262, and 0.258, respectively performed better than the remaining models and had the prediction capability to capture the RON dependence on predictor variables. ET and RT had an R2 value of 0.94 and 0.89, respectively. The GPR model was used as a surrogate model for fitness function evaluations in two optimisation frameworks based on genetic algorithm and particle swarm method. Optimal parameter values found by the optimisation methodology increased the RON value by 3.52%. The proposed methodology of surrogate‐based optimisation will provide a platform for plant‐level implementation to realise the concept of industry 4.0 in the refinery.
Dynamic spatial‐temporal network for traffic forecasting based on joint latent space representation
Authors: Yu Qian , Ma Liang , Lai Pei , Guo Jin
Published: May 2024

In the era of data‐driven transportation development, traffic forecasting is crucial. Established studies either ignore the inherent spatial structure of the traffic network or ignore the global spatial correlation and may not capture the spatial relationships adequately. In this work, a Dynamic Spatial‐Temporal Network (DSTN) based on Joint Latent Space Representation (JLSR) is proposed for traffic forecasting. Specifically, in the spatial dimension, a JLSR network is developed by integrating graph convolution and spatial attention operations to model complex spatial dependencies. Since it can adaptively fuse the representation information of local topological space and global dynamic space, a more comprehensive spatial dependency can be captured. In the temporal dimension, a Stacked Bidirectional Unidirectional Gated Recurrent Unit (SBUGRU) network is developed, which captures long‐term temporal dependencies through both forward and backward computations and superimposed recurrent layers. On these bases, DSTN is developed in an encoder‐decoder framework and periodicity is flexibly modeled by embedding branches. The performance of DSTN is validated on two types of real‐world traffic flow datasets, and it improves over baselines.
Formation of N–bearing complex organic molecules in molecular clouds: Ketenimine, acetonitrile, acetaldimine, and vinylamine via the UV photolysis of C2H2 ice
Authors: Chuang K.-J. , Jäger C. , Santos J. C. , Henning Th.
Published: May 2024

Context. The solid-state C2H2 chemistry in interstellar H2O-rich ice has been proposed to explain astronomically observed complex organic molecules (COMs), including ketene (CH2CO), acetaldehyde (CH3CHO), and ethanol (CH3CH2OH), toward early star-forming regions. This formation mechanism is supported by recent laboratory studies and theoretical calculations for the reactions of C2H2+OH/H. However, the analog reaction of C2H2+NH2 forming N-bearing species has been suggested to have a relatively low rate constant that is orders of magnitude lower than the value of C2H2+OH.

Aims. This work extends our previous laboratory studies on O-bearing COM formation to investigate the interactions between C2H2 and NH3 ice triggered by cosmic ray-induced secondary UV photons under molecular cloud conditions.

Methods. Experiments were performed in an ultra-high vacuum chamber to investigate the UV photolysis of the C2H2:NH3 ice mixture at 10 K. The ongoing chemistry was monitored in situ by Fourier-transform infrared spectroscopy as a function of photon fluence. The IR spectral identification of the newly formed N-bearing products was further secured by a quadrupole mass spectrometer during the temperature-programmed desorption experiment.

Results. The studied ice chemistry of C2 H2 with NH2 radicals and H atoms resulting from the UV photodissociation of NH3 leads to the formation of several N-bearing COMs, including vinylamine (CH2CHNH2), acetaldimine (CH3CHNH), acetonitrile (CH3CN), ketenimine (CH2CNH), and tentatively ethylamine (CH3CH2NH2). The experimental results show an immediate and abundant CH2CHNH2 yield as the first-generation product, which is further converted into other chemical derivatives. The effective destruction and formation cross-section values of parent species and COMs were derived, and we discuss the chemical links among these molecules and their astronomical relevance.

Published: May 2024

This research addresses the challenge of elevated temperatures impacting the performance of photovoltaic (PV) panels, considering both the dimensions of the cooling tube and the flow of water. A comprehensive analysis of various water flow rates is conducted using three tubes (tube 1, tube 2, and tube 3) with cross-sections of 100.27, 148.27, and 202.27 mm2 and 15, 11, and 9 loops, respectively. The numerical results reveal a significant 41.66% reduction in PV cell temperature, decreasing from 60 °C to 35 °C using tube 3 at a flow rate of 7.5 L/min, reflecting high electrical performance and efficiency. Meanwhile, at a flow rate of 1.5 L/min, tube 1 delivers optimum hot water at the outlet with a temperature of 55.6 °C. The proposed design significantly contributes to PV cell efficiency, emphasizing the impact of cooling tube dimensions on the overall efficiency of the PV/T system. This study introduces an innovative approach using a flat oval tube to minimize temperature elevation and simultaneously generate hot water. The innovative PV/T system demonstrates potential advancements in thermal management and lays the foundations for future sustainable energy applications.
Characterizing pediatric head patient size in Moroccan population: Establishing age-dependent relationships for accurate CT dose estimation
Authors: Sekkat H. , Elmansouri K. , Khallouqi A. , Halimi A. , El Rhazouani O. , Tahiri Z. , Talbi M. , El Mansouri M.
Published: May 2024

Accurate dose estimation in computed tomography (CT) scans is crucial and relies on precise normalization of output dose, typically measured by the volume CT dose index (CTDIvol). Key metrics, including effective diameter (Deff) and water-equivalent diameter (Dw), play pivotal roles in characterizing patient size. However, a notable gap exists in delineating the specific relationships between age and head patient size (Deff and Dw) for pediatric patients in Morocco. The primary objective of this study was to establish these critical associations between patient age and head patient size (Deff and Dw), providing a foundation for calculating size-specific dose estimates (SSDE) in pediatric head CT examinations. A retrospective analysis of data from 134 pediatric patients, aged 0–13 yr, comprising 71 males and 63 females who underwent head CT scans, was conducted. Utilizing the Radiant DICOM Viewer, patient sizes were measured in terms of both lateral and anterior-posterior dimensions for Deff and Dw calculations based on CT images in DICOM format. Our analysis revealed robust correlations between patient size (Deff and Dw) and the patient’s age, with R2 values ranging from 0.65 to 0.86. Notably, larger Dw values were consistently observed compared to Deff. For male patients, Deff measurements ranged from 9.02 to 18.77 cm, with Dw values spanning 9.83 to 20.16 cm. Female patients exhibited Deff values ranging from 8.77 to 17.41 cm and Dw values ranging from 8.92 to 18.37 cm. These findings shed light on the crucial relationship between age and patient size, facilitating more precise dose calculations.
Canonical Transformations and Poisson Theory for Dynamics with Non-Standard Lagrangians
Authors: ZHU Lin , ZHANG Yi
Published: May 2024

The canonical transformation and Poisson theory of dynamical systems with exponential, power-law, and logarithmic non-standard Lagrangians are studied, respectively. The criterion equations of canonical transformation are established, and four basic forms of canonical transformations are given. The dynamic equations with non-standard Lagrangians admit Lie algebraic structure. From this, we establish the Poisson theory, which makes it possible to find new conservation laws through known conserved quantities. Some examples are put forward to demonstrate the use of the theory and verify its effectiveness.

Authors: Schindowski Eva Maria , Vollenweider Franz X.
Published: May 2024

Der Artikel stellt 2 Behandlungsverläufe von Patienten mit rezidivierender Depression gegenüber, welche mit Psilocybin behandelt wurden. Weltweit wächst stetig die Anzahl Studien, die die Verwendung von Psilocybin zur Behandlung von Depressionen untersuchen und damit mehr und mehr das Interesse an dieser Therapieform. Während einige Kollegen aus dem Forschungsumfeld einen aktuellen „Hype“ um die Wirkung von Psychedelika bemerken, machen Patienten und ihre begleitenden Behandler sehr unterschiedliche Erfahrungen in der konkreten Anwendung der Substanz. Es gibt nur wenige detaillierte Beschreibungen von Langzeitverläufen, die Außenstehenden, die sonst keine Berührungspunkte mit der klinischen Anwendung im Forschungsrahmen oder in anderen legalen Settings haben, einen tieferen Einblick in diese Art der Therapie ermöglichen. Die hier genannten Fallbeispiele zeigen einerseits das enorme Potenzial von Psilocybin, das Leben depressiver Patienten positiv zu beeinflussen, andererseits sollte nicht vernachlässigt werden, dass es weiterhin Patienten gibt, die auch bei wiederholter Anwendung keinen langfristigen Nutzen erfahren.

Authors: Maduratna Ernie , Sari Desi Sandra , Rahayu Retno Puji , Masya Resgita Nadila , Adinar Noor
Published: May 2024

Objective The main principle in preventing periodontal disease is to improve oral hygiene. The bacteria that cause the onset of periodontal disease, one of which is the Porphyromonas gingivalis bacterium, causes inflammation. Persistent inflammation causes tissue damage and alveolar bone resorption by secreting proinflammatory cytokines, matrix metalloproteinase-9 (MMP-9), prostaglandin E2 (PGE-2), and anti-inflammatory cytokines. In this case, preventive treatment is needed, such as using toothpaste that contains anti-inflammatories so that the progression of the disease does not get worse. The traditional ingredient currently being developed is Nigella sativa, which has anti-inflammatory properties. Therefore, this study analyzes the potential of toothpaste containing Nigella sativa on the expression of tumor necrosis factor-α (TNF-α), MMP-9, and PGE-2 in the Wistar rat model induced by Porphyromonas gingivalis bacteria. This study aims to prove the potential of Nigella sativa toothpaste to decrease the expression of PGE-2, TNF-α, and MMP-9 in the gingiva of rats induced by Porphyromonas gingivalis bacteria.

Materials and Methods Forty-five healthy male Wistar rats were used, consisting of the negative control group, which was only injected with Porphyromonas gingivalis bacteria ATCC3322. The positive control group was given enzyme toothpaste, and the treatment group was assigned 1 mg of Nigella sativa paste using a microbrush for 30 seconds on the gingiva incisors mandibular with a circular motion, given two times a day for a week. Immunohistochemical to see the expression of TNF-α, PGE-2, and MMP-9. Parametric comparative analysis using a one-way analysis of variance test was performed to analyze differences between groups.

Results and Discussion Nigella sativa toothpaste significantly reduced proinflammatory cytokines, as seen through the expression of TNF-α, PGE-2, and MMP-9 on days 3, 5, and 7 (p <0.05).

Conclusion In the limit of studied animal model, this trial indicates that giving toothpaste with black seed extract (Nigella sativa) could inhibit inflammatory mediators, as seen from the decreased expression of MMP-9, TNF-α, and PGE-2 seen from the 3rd, 5th, and 7th days.

Published: May 2024

Objectives The durability of ceramic is crucial, which is probably influenced by aging. This study evaluated the effect of aging on flexural strength of different ceramics.

Materials and Methods One-hundred twenty ceramic discs (Ø 12 mm, 1.5 mm thickness) were prepared from zirconia-reinforced lithium silicate (ZLS, C), lithium disilicate (LS2, E), precolored yttria-stabilized tetragonal zirconia polycrystalline (Y-TZP, Ip), and customized color Y-TZP (Ic). Samples were randomly divided into two groups for accelerated aging (A) between 5 and 55°C water baths, 30-second immersing time each, for 10,000 cycles, and nonaged group (N), serving as control. Biaxial flexural strength (σ) was evaluated utilizing the piston-on-three-balls at 0.5 mm/min speed. Analysis of variance and Tukey comparisons were determined for significant differences (α = 0.05). Weibull analysis was applied for survival probability, Weibull modulus (m), and characteristic strength (σo). Microstructures were evaluated with scanning electron microscopy and X-ray diffraction (XRD).

Results The highest σ and σo were seen for IcN, followed by IcA, IpN, IpA, EN, CA, CN, and EA, respectively. CN showed the highest m, while EA showed the lowest m. Significant differences of σ for each ceramic were indicated (p < 0.05). Aging caused a significant difference in σ (p < 0.05). XRD showed t→m phase transformation of Ip and Ic after aging.

Conclusion Aging affected strength of ceramics. Comparable strength between LS2 and ZLS was evidenced, but both were less strength than Y-TZP either aging or non-aging. Comparable strength between precolored Y-TZP and customized color Y-TZP was indicated. Better resisting aging deterioration of Y-TZP than LS2 and ZLS is suggested for fabrication restorative reconstruction.
Establishment of an equity evaluation method for urban parkland layout under the process-outcome perspective
Authors: Guo Yuhan , Cao Yilun , Li Yue , Wang Runjue , Fang Yuhao
Published: May 2024

Urban parkland, as a critical component of urban green space, reflects the distribution of public resources. Combined with the concept of the 15-min Living Circle, this paper comprehensively evaluated the equity of urban parkland in the Central Area of Zhengzhou from a process-outcome perspective and established an evaluation method for assessing the equity of parkland in high-density urban areas. The objective of this approach is to provide a systematic and applicable evaluation method for metropolises that is more comprehensive than traditional evaluation methods, which rely solely on accessibility. In terms of process equity, spatial equity values were calculated using the Three Step Catchment Area Method (3SFCA) with walking and bicycle travel models. For outcome equity, Zone Entropy was utilized with demographic characteristics. The results illustrated that the overall accessibility and equity of urban parkland layout in the Central Area of Zhengzhou were inferior, with an extensive number of blind service areas and serious polarization. The Zone Entropy varied considerably among streets, which indicated significant differences in the allocation of parkland and population. Further analysis illustrated that economic factors, such as house prices, were not significantly relevant to parkland equity. Instead, geographic factors such as location and intensity of development had a remarkable impact on parkland equity. Although urban parkland layout has been prone to the elderly, the total number of park spaces is still insufficient. In the long run, the construction of the 15-min Living Circle still needs to be vigorously promoted in the research area.

Published: May 2024

In this paper, a method for simulating the instability transient process of the axial compression system based on the body-force model is developed, and a corresponding simulation program is developed. Simulations of the transient process of instability were carried out on a high-speed four-stage compressor and compared with experimental data. At 50% of the design rotational speed, the type of instability was rotating stall, and the simulated and experimental stall cell propagation speed were very close to each other. At 70% of the design rotational speed, the type of instability was surge. A “surge loop” was simulated, and the surge period and the percentage of time spent in each phase were consistent with the experiments. The simulation successfully predicted the blockage in the surge re-pressurization phase, proving the reliability of the simulation results. In addition, the computation yields more information about the flow field. By summing the blade forces of all grids on a blade row by volume, the surge loadings are obtained. The analysis of the axial momentum equation shows that the obtained blade force variations are reasonable. The simulation time of the multistage axial compressor is greatly reduced compared to the full annulus three-dimensional unsteady Reynolds-averaged Navier–Stokes method, demonstrating its great advantage in the design phase of the compressor.
Dynamics of tandem bubble interaction near tissue
Authors: Zhao Junjie , Wang Jingzhu , Cao Shunxiang
Published: May 2024

A high-fidelity multiphase flow computational model is utilized to investigate the interaction mechanism between anti-phase tandem bubbles and tissue materials in a free-field environment. The formation of liquid jets generated by tandem bubble coupling and its effects on tissue deformation are analyzed. Parametric studies are conducted to explore the impacts of bubble–bubble distance (γbb), bubble size ratio (Sbb), and bubble–tissue distance (γtb). The results indicate that the regime of tissue penetration varies under different γbb. For small γbb, the tissue deformation is mainly attributed to the stretching of upper bubbles and liquid jets; whereas for large γbb, tissue deformation is primarily induced by the jets themselves; and for moderate γbb values, it is caused by a combined effect involving both jets and the evolution of toroidal bubbles. Comparative analysis shows the significant impact of varying Sbb on bubble coupling dynamics, with larger Sbb values correlating with more potent tissue penetration. Furthermore, the study also reveals that, beyond γtb exceeding 3, penetration ceases to manifest, advocating for the maintenance of γtb below 1.4 for practical applications.
The kinetic theory of prompt redeposition in the case of thin Debye sheath
Authors: Marenkov E. D.
Published: May 2024

Prompt redeposition is a process in which a neutral atom sputtered from a divertor target or the first wall of a tokamak returns on the surface right after ionization, before experiencing any collisions with the background plasma. This paper presents analytical solutions of kinetic equations for sputtered neutrals and resulting ions. Using obtained distribution functions, the redeposition coefficient and average impact angle are derived under assumptions of thin Debye sheath. Our expression for the prompt redeposition coefficient explicitly depends on the angular and energy distributions of sputtered atoms and, therefore, is more universal than often used Fussmann equation valid only for cosine distribution. The effect of the angular distributions of sputtered particles on the prompt redeposition efficiency and parameters of redeposited ions is analyzed.

Published: May 2024

The development of large-scale manufacturing and cost-saving artificial synaptic devices is of great significance for the realization of hardware neural networks. In this work, the In2O3 synaptic transistors with boron ion-doped ZrOx as the dielectric layer were fabricated by the solution process. The large counterclockwise hysteresis indicates that the nonvolatile memory capacity of the synaptic transistors was improved by boron ions doping. Typical synaptic functions including excitatory postsynaptic current, paired pulse facilitation, and high-pass filtering properties were simulated by applying gate bias. The multilevel channel conductance can be modulated by successive positive and negative pulses. Additionally, small nonlinearities were shown in the potentiation and depression processes, and high accuracies of 92.0% (small digits) and 93.8% (large digits) were obtained in digital recognition training. This study indicates that oxide-gated synaptic transistors based on the boron ions doping strategy show great potential for neuromorphic applications.
Superior optical gain in zinc selenide colloidal nanocrystals induced by Coulomb-correlated electron–hole plasma

Published: May 2024

Colloidal semiconductor nanocrystals (NCs) have been recognized as promising solution-processable gain media; however, the lasers with state-of-the-art performance exclusively originate from the cadmium- and lead-based NCs. Herein, we for the first time unravel that high-quality heavy-metal-free ZnSe/ZnS NCs show superior optical gain and lasing performance when the sizes exceed the quantum confinement regime. Corroborated by comprehensive transient spectroscopy, we reveal that the optical gain in large ZnSe/ZnS NCs originates from the novel Coulomb-correlated electron–hole plasma (C-EHP) instead of high-order multi-exciton recombination. Thanks to the formation of a four-level system and the suppression of Auger recombination, the C-EHP renders low gain threshold (9.4 μJ/cm2), high gain coefficient (>6500 cm−1), and long gain lifetime (∼4 ns). Such desirable gain properties compete well with those of classic CdSe NCs and enable the construction of a high-performance laser device. This work represents significant progress toward the development of solution-processable non-heavy-metal nanocrystal lasers.

Two-dimensional (2D) van der Waals heterostructures (vdWHs) received intensive interest due to their amazing physical properties and broad applications in fields such as ultrasensitive sensors, transistors, and solar cells. Although remarkable progresses were achieved for the synthesis of 2D vdWHs, great challenges still remain for the easy preparation of 2D vdWHs because of the weak interlayer coupling. As a type of 2D semiconductor, the 2D SnSe film is particularly appealing for optoelectronic and thermoelectric devices because of its high thermoelectric and optoelectronic performance. However, the easy preparation of large-area and high-quality 2D SnSe films remains a great challenge. In this work, we proposed an approach to regulate the preparation of high-quality 2D vdWHs, which employed the polarization field of substrate as a key factor to control the diffusion barriers of the adsorbed Sn and Se atoms. Hexagonally stacking α-In2Se3 was selected as such polarized substrate because this substrate exhibits out-of-plane ferroelectricity with upward or downward polarized states at room temperature, and the two degenerated polarized states can be easily switched by applying an external electric field. It was revealed that the polarization field of α-In2Se3 can substantially influence the diffusion behavior of Sn and Se atoms on polarized α-In2Se3 substrate. So, the film growth property of SnSe film is sensitive to the polarization direction of In2Se3 substrate. Our research provides an ideal method to explore the possibility of building 2D functional nanoelectronic devices.
Investigating integrodifferential equations associated with fractal–fractional differential operators
Authors: Gokulvijay G. , Sabarinathan S.
Published: May 2024

This study focuses on integrodifferential equations involving fractal–fractional differential operators characterized by exponential decay, power law, and generalized Mittag–Leffler kernels. Utilizing linear growth and Lipschitz conditions, we investigate the existence and uniqueness of solutions, as well as the Hyers–Ulam stability of the proposed equations. For every instance, a numerical method is utilized to derive a numerical solution for the specified equation. The paper includes illustrations of fractal–fractional integrodifferential equations, with their precise solutions determined and subsequently compared with the numerical outcomes. This methodology can be applied to demonstrate convergence, and graphical presentations are included in relevant examples to illustrate our proposed approach.
Existential, locative and possessive predication in Kamas
Authors: Däbritz Chris Lasse , Wagner-Nagy Beáta
Published: May 2024

This paper describes and analyses existential, locative and possessive predications in Kamas. Starting from a
functional-semantic perspective, we show that the three types of predications share many features, but they also exhibit some
important differences. Given that two layers of Kamas can be distinguished, we demonstrate that the reactivated Kamas of the last
speaker, Klavdiya Plotnikova, exhibits some peculiarities which can be explained partly by Russian influence. The most important
result of the study is that the boundaries between the three predication types are rather fluid in Kamas, whereas the distinction
between affirmative and negative clauses is morphosyntactically unambiguously manifested. This polarity split, given that it is
seldom recognised in the general literature, may provide important implications for linguistic typology and theory.
Plasma in liquids induced modification of Cu surfaces
Authors: Pottkämper P , von Keudell A
Published: May 2024

Copper oxide surfaces are commonly used as the catalyst for the CO2 reduction reaction towards hydrocarbons. However, the lifetime of these catalyst surfaces is limited. In this paper, a method of production of copper oxides through in-liquid plasma is explored, which may be a suitable reactivation method in such applications. The influence of the plasma, ignited in distilled water, with copper and its oxides is monitored in − situ using infrared spectroscopy and ex-situ using scanning electron spectroscop and x-ray photoelectron spectroscopy of the samples. It is shown that the interaction of the plasma with the samples causes a reduction of the copper oxide on a fast time scale and an oxidation on a longer time scale. The formation of preferentially oriented copper nanocubes is observed.
Development of nickel vanadium-impregnated activated carbon nanocomposites for electrocatalytic conversion of furfural into fuels

Published: May 2024

Furfural, derived from biomass, is crucial for achieving carbon neutrality through biomass utilization. It can be converted into furfuryl alcohol and other valuable components used in the chemical industry. Electrochemical methods offer improved selectivity in the conversion of furfural under mild conditions compared to traditional hydrogenation. This study investigates the electrocatalytic conversion of furfural using a hydrothermally synthesized nickel-vanadium-impregnated activated carbon catalyst. The developed catalysts were characterized by x-ray diffraction, scanning electron microscopy, energy dispersive spectroscopy and x-ray photoelectron spectroscopy. The as-developed catalyst was used to synthesize electrodes for the electrochemical conversion of furfural. The behavior was investigated using electrochemical impedance spectroscopy and linear sweep voltammetry. The study optimized the Ni:V ratio, applied voltages, electrolyte molarity and reaction time and found that a Ni:V ratio of 1:1 resulted in maximum furfural conversion. The Ag/AgCl cathode at −0.9 V showed a low reaction rate, thus requiring higher voltages for efficient conversion. LC-UV-ESI MS analysis of the cathode half-reaction revealed the formation of a nitrogen-containing compound, likely stemming from the reaction between furfural and acetonitrile under the influence of the catalyst. This study demonstrates the effectiveness of NiV/AC catalysts in the electrocatalytic conversion of furfural, with a conversion rate of 90% and a faradaic efficiency of around 30% at −1.3 V. Furthermore, a plausible reaction mechanism was proposed.
