MHD convective rotating flow of viscoelastic fluid past an infinite vertical oscillating porous plate with Hall effects
Authors: Raju G. , Hari Babu B. , Rama Mohan Reddy L. , Varma S. V. K. 
Published: November 2022

AbstractIt is considered the unsteady and incompressible magnetohydrodynamic rotating free convection flow of viscoelastic fluid with simultaneous heat and mass transfer near an infinite vertical oscillating porous plate under the influence of uniform transverse magnetic field and taking Hall current into account. The governing equations of the flow field are then solved by a regular perturbation method for a small elastic parameter. The expressions for the velocity, temperature, and concentration have been derived analytically and also its behavior is computationally discussed with reference to different flow parameters with the help of graphs. The skin friction on the boundary, the heat flux in terms of the Nusselt number, and the rate of mass transfer in terms of the Sherwood number are also obtained and their behavior discussed. The resultant velocity enhances with increasing Hall parameter and rotation parameter. The reversal behavior is observed with increasing viscoelastic parameters. The resultant velocity enhances and experiences retardation in the flow field with increasing radiation parameters, whereas the secondary velocity component increases with increasing rotation parameters. The temperature diminishes as the Prandtl number and/or the frequency of oscillations. The concentration reduces at all points of the flow field with the increase in the Schmidt number.
On the wisdom and utility of (under)sociality: A consumer psychology perspective
Authors: Silver Ike , Small Deborah A. 
Published: November 2022

AbstractKumar and Epley (2023) review robust evidence for an intriguing hypothesis: That people fail to appreciate the benefits of everyday social behaviors and thus hesitate to connect with others in ways that would increase well‐being. In this commentary, we discuss how consumer research can enrich theory and application in this emerging line of inquiry. We suggest (a) that the hedonic implications of undersociality can be integrated with reputational signaling insights to generate new questions about the wisdom and utility of social behavior, and (b) that undersociality has interesting implications for a consumption domain of particular interest to maximizing welfare: charitable giving.

AbstractQuinolin‐2‐one represents an important and valuable chemical motif that possesses a wide variety of biological activities; however, the anti‐influenza activities of quinolin‐2‐one‐containing compounds were rarely reported. Herein, we describe the screening and identification of 3‐aryl‐quinolin‐2‐one derivatives as a novel class of antiviral agents. The 3‐aryl‐quinolinone derivatives were synthesized via an efficient copper‐catalyzed reaction cascade that we previously developed. Using this synthetic method, preliminary structure–activity relationships of this scaffold against the influenza A virus infection were systematically explored. The most potent compound 34 displayed IC50 values of 2.14 and 4.88 μM against the replication of H3N2 (A/HK/8/68) and H1N1 (A/WSN/33) strains, respectively, without apparent cytotoxicity on MDCK cells. We further demonstrated that 27 and 34 potently inhibited the plaque formation of the IAV, rendering this scaffold attractive for pursuing novel anti‐influenza agents.

AbstractIn 2022, many monkeypox (MPX) outbreaks have been documented in countries where MPX was not endemic. It spread all around the world, especially in European Union and United States. While MPX is classically considered to be transmitted through close contact with lesions, the hypothesis of sexual transmission has been proposed. This study considered a total of 49 patients suspected for MPX that were also tested for other sexually transmitted infections (STIs), including Chlamydia trachomatis, Neisseria gonorrhoeae, Mycoplasma genitalium, and Trichomonas vaginalis.The data from coinfected patients suggested that MPXV and STIs might share the same route of inoculum, corroborating the hypothesis of possible sexual transmission for the emerging poxvirus. And like any other STI, MPX should be considered without stigmatization.

AbstractAdvanced manufacturing has received considerable attention as a tool for the fabrication of cell scaffolds however, finding ideal biocompatible and biodegradable materials that fit the correct parameters for 3D printing and guide cells to align remain a challenge. Herein, a photocrosslinkable smectic‐A (Sm‐A) liquid crystal elastomer (LCE) designed for 3D printing is presented, that promotes cell proliferation but most importantly induces cell anisotropy. The LCE‐based bio‐ink allows the 3D duplication of a highly complex brain structure generated from an animal model. Vascular tissue models are generated from fluorescently stained mouse tissue spatially imaged using confocal microscopy and subsequently processed to create a digital 3D model suitable for printing. The 3D structure is reproduced using a Digital Light Processing (DLP) stereolithography (SLA) desktop 3D printer. Synchrotron Small‐Angle X‐ray Diffraction (SAXD) data reveal a strong alignment of the LCE layering within the struts of the printed 3D scaffold. The resultant anisotropy of the LCE struts is then shown to direct cell growth. This study offers a simple approach to produce model tissues built within hours that promote cellular alignment.

Published: November 2022

AbstractThis study explores the influence of external reference price and store brand awareness on consumers' internal reference price, transaction utility, purchase intention, and search intention in mobile commerce. A 3 × 2 two‐factor experimental design for both utilitarian and hedonic products was adopted to collect the sample data. A total of 189 valid responses were analyzed using a MANOVA approach. The results indicate that for the utilitarian product context, external reference price affects consumers' internal reference price, transaction utility, and purchase intention but does not affect search intention and that store brand awareness affects consumers' internal reference price, transaction utility, purchase intention, and search intention. Further, store brand awareness has a moderating effect on the relationship between external reference price and internal reference price. For the hedonic product context, external reference price affects consumers' internal reference price and transaction utility but does not affect purchase intention or search intention, while store brand awareness affects consumers' internal reference price, transaction utility, purchase intention, and search intention. Also, store brand awareness has a moderating effect on the relationship between external reference price and search intention. These findings provide several important theoretical and practical implications for mobile commerce pricing decisions.
The dual role of state shareholders in disclosed corporate misconduct: Evidence from China
Authors: Hu Chenhao 
Published: November 2022

AbstractBy adopting a legitimacy perspective rooted in institutional theory, this study investigates the dual role of state ownership in corporate misconduct in emerging economies: monitoring role constraining misconduct commission and patronage role leading to less disclosure. Using a sample of listed firms in China, we find a negative relationship between state ownership and corporate misconduct. Furthermore, the negative effect of state ownership on misconduct will be stronger when the firm affiliation is high and the firm has politically connected executives. The impact will be weaker when the number of local listed firms is greater and the regional inspection is intense.

AbstractSubjectThe Angiopoietin‐like 3 (ANGPTL3) gene has been reported to be associated with cardiovascular risk. This study is designed to compare the genetic variant (rs1748195) of the ANGPTL3 gene and the presence of a coronary artery occlusion of >50% in Iranian nation.MethodIn this study, 184 patients underwent angiography and 317 healthy individuals were evaluated for polymorphism of rs1748195 the ANGPTL3 gene using Tetra‐ARMs PCR. Coronary patients who experience angiography were categorized into two groups: 54 patients who had an angiography indication for the first time and coronary occlusion was <50% (Angio−) and 134 patients who formerly underwent coronary stent implanting at least 1 month before with coronary occlusion of ≥50% that again have an angiography indication (Angio+).In addition, individuals with angio+ are categorized in two groups: (1) non‐in‐stent restenosis (NISR); patient with a patent stent (N = 92). (2) in‐stent restenosis (ISR); in‐stent stenosis >50% (N = 42).ResultThe fundamental of characteristics of our study design population was categorized based on undergoing angiography or not. In the present study, we investigated that the CC genotype, and also the A allele corresponding to rs1748195 at the ANGPTL3 gene loci, was associated with negative angiogram and directly related to the risk of coronary occlusion >50%. In contrast, this result was not significant in genotypes of ANGPTL3 between non‐ISR and ISR groups.ConclusionThe outcomes of this study showed that rs1748195 polymorphism at the ANGPTL3 gene loci is associated with an elevated risk for the existence of a coronary occlusion of >50%.

ScopeEpidemiological evidence associates the consumption of cruciferous vegetables with reduced risk of several cancers, including renal cell carcinoma. Erucin can be generated by in vivo reduction of sulforaphane or by enzymatic hydrolysis of glucoerucin. Contrarily to sulforaphane, only limited studies have addressed the anticancer properties of erucin. This study aims at evaluating the impact of erucin on renal cell biology.Methods and ResultsThe effects of erucin were assessed in 786‐O and Vero‐E6 cells, representative of human renal cancer and non‐ cancer kidney cells, respectively. Erucin induced a concentration‐dependent decrease in cell viability and cell cycle arrest at G2/Mitosis. In Vero‐E6 cells erucin modestly reduced intracellular reactive oxygen species levels while in 786‐O no effects were detected. After erucin treatment, both cell lines revealed altered morphology, with a concentration‐dependent change from an elongated shape towards a smaller round conformation. Moreover, erucin affected cell adhesion and strongly altered the tubulin network structure and specifically microtubule polymerization. These results are in line with the observed decrease in collective and single cell migration and G2/Mitosis arrest.ConclusionsOverall, erucin may have a beneficial impact in reducing the motility of renal cancer cells. Our results contribute to explore possible dietary approaches for secondary/tertiary renal cancer chemoprevention.

Published: November 2022

AbstractBackgroundMany learning‐based low‐dose (LD) computed tomography (CT) imaging methods require large paired full‐ and low‐dose datasets for training, which are usually unavailable in clinic. Whereas models trained on simulated data often face the generalization problem on real clinical data.PurposeTo develop an unsupervised learning technique to acquire clean CT projection from its adjacent LD projections.MethodsGiven a sequential LD projection set, the method extracts out the middle projection as the target and treats the rest ones as the input. The model is trained with the mean absolute error with proposed inter‐view gradient constraint term, which helps to suppress outliers and preserve edges in the denoised projection. The simulated low‐dose CT grand challenge dataset and a real physical torso phantom dataset were employed for experiment. The peak signal to noise ratio (PSNR) and structural similarity index measure (SSIM) were calculated for quantitative evaluation.ResultsIn experiments with both the simulated and real datasets, visual comparisons reveal that the proposed method obtained images superior to unsupervised and supervised methods working in both image and projection domain. For numerical comparison, our method obtains larger SSIMs than other unsupervised methods at quarter and eighth dose levels. As for PSNR, our method obtains larger value at eighth dose whereas smaller value at quarter dose. The supervised models obtain better numerical results than all unsupervised models on simulated datasets.ConclusionThe proposed method can reduce the noise in CT projections effectively, making it an attractive tool for practical LDCT pre‐processing.

Published: November 2022

AbstractThe Polytetrafluoroethylene (PTFE)/Kevlar fabric/phenolic composites have been widely used as self‐lubricating materials owing to their excellent properties. In this study, the tribological properties of PTFE/Kevlar fabric composites under different temperatures (25–150°C) were studied showing the lowest wear rate and friction coefficient at 75°C. The effect of temperature on wear behavior of fabric/phenolic composites was revealed through the analysis of friction surfaces, wear debris, and transfer films. To be specific, the improvement of tribological properties occur in a temperature range of 25–75°C being predominantly caused by the abrasive wear, whereas in the range of 75–150°C, the tribological properties decreased because of the adhesive wear. According to this phenomenon, the friction and wear test of the fabric composite after pre‐grinding at 75°C shows a great improvement of coefficient of friction (COF) and wear rate about 30%. The study of the wear behavior at different temperatures is important for the application and properties improvement of self‐lubricated composites.

AbstractThe aim of present study is to enhance the tensile strength, elongation at break and tensile modulus of polyamide 6/carbon nanotube (PA6/CNT) nanocomposite prepared by selective laser sintering. For this purpose, the optimal values of laser power, scanning speed and CNT content were estimated to enhance the tensile properties of PA6/CNT nanocomposite by using the response surface methodology and desirability function. The microstructure of specimens was observed using the scanning and transmission electron microscopy. It was observed that an increase in laser power from 5 to 10 W improved the tensile strength (21%) and elongation at break (11.4%) of the nanocomposite due to uniform dispersion of CNTs, while the further increase of laser power reduced the tensile strength (5.2%), elongation at break (5.8%) and tensile modulus (5.3%) due to thermal degradation of PA6 polymer. A rise of the scanning speed from 1000 to 2000 mm/s was associated with a reduction in the tensile strength, elongation at break and tensile modulus by about 8.3%, 13% and 3.3% respectively, which was due to lower heat input and consequently incomplete densification of the nanocomposite. The addition of CNTs up to 5 wt% can enhance the tensile properties of PA6/CNT nanocomposite, but needs increasing the laser power. The best combination of tensile properties was achieved at laser power of 7.3 W, scanning speed of 1000 mm/s and CNT content of 1.8 wt%. Moreover, the addition of CNTs up to 5 wt% showed a slight influence on thermal stability and crystallinity of the sintered nanocomposite.

AbstractBackgroundThe wildfire disease on tobacco can seriously hinder plants. Meanwhile, its pathogen, Pseudomonas syringae, can also infect over 200 plants and threat agriculture production. However, the disease usually occurs after summer rains which washes away most copper (Cu)‐based bactericides, allowing the disease to invade. Therefore, we fabricate a new nanogel with high disease control and anti‐erosion ability and study the effects of the reductant on the performance of the copper oxide nanoparticle (CuONP) composite nanogel.ResultsPolydopamine (PDA) is a polycation for both in situ reduction of CuONP in alginate nanogels and for adjusting the copper ion (Cu2+) releasing rate in this work. The composite nanogel fabricated by PDA (PDA‐CuONP@ALGNP@CTAC) had a higher Cu2+ releasing rate, damaging the pathogen membrane more efficiently, allowing for better disease control and plant growth promotion when compared to sodium borohydride (SBH)‐fabricated nanogel (SBH‐CuONP@ALGNP@CTAC) or the commercial bactericide, thiodiazole copper. The PDA‐CuONP@ALGNP@CTAC had a high anti‐erosion ability and could remain adhered to the leaf surface even after five rain event simulations.ConclusionThe addition of polycations (like PDA) into CuONP composite nanogel could increase the Cu2+ releasing rate, resulting in improved disease management when compared to SBH‐CuONP@ALGNP@CTAC or thiodiazole copper. The PDA containing gel had an improved anti‐erosion ability and water resistance. This new composite nanogel has a high potential for wildfire disease control, improving agricultural production. © 2022 Society of Chemical Industry.
