Published: June 2024

AbstractIn order to solve the problems of low transmission rate and large device size of electro-optical modulator, an electro-optic half subtractor based on silicon-based hybrid surface plasmon polariton waveguide is proposed in this study. The proposed device utilizes three units metal-oxide-semiconductor capacitor structure to achieve the half subtractor logic function of electro-optic control, improving the transmission rate of the electro-optic half subtractor while also reducing the device size using surface plasmon polariton technology, with a size of only 32 μm × 4.3 μm. At the same time, the use of hybrid silicon waveguides reduces the sharp Ohmic attenuation caused by surface plasmon polaritons and reduces optical insertion losses (ILs). The simulation results show that when the electro-optic half subtractor operates at the wavelength of 1,550 nm, the IL difference is 1.0 dB in each state, the transmission rate of the device is 0.75 Tbit/s, and the energy consumption is 12.69 fj/bit.

Abstract
In this study, we present a novel approach to enable high-throughput characterization of transition-metal dichalcogenides (TMDs) across various layers, including mono-, bi-, tri-, four, and multilayers, utilizing a generative deep learning-based image-to-image translation method. Graphical features, including contrast, color, shapes, flake sizes, and their distributions, were extracted using color-based segmentation of optical images, and Raman and photoluminescence spectra of chemical vapor deposition-grown and mechanically exfoliated TMDs. The labeled images to identify and characterize TMDs were generated using the pix2pix conditional generative adversarial network (cGAN), trained only on a limited data set. Furthermore, our model demonstrated versatility by successfully characterizing TMD heterostructures, showing adaptability across diverse material compositions.

Impact Statement
Deep learning has been used to identify and characterize transition-metal dichalcogenides (TMDs). Although studies leveraging convolutional neural networks have shown promise in analyzing the optical, physical, and electronic properties of TMDs, they need extensive data sets and show limited generalization capabilities with smaller data sets. This work introduces a transformative approach—a generative deep learning (DL)-based image-to-image translation method—for high-throughput TMD characterization. Our method, employing a DL-based pix2pix cGAN network, transcends traditional limitations by offering insights into the graphical features, layer numbers, and distributions of TMDs, even with limited data sets. Notably, we demonstrate the scalability of our model through successful characterization of different heterostructures, showcasing its adaptability across diverse material compositions.

AbstractNi, Pt, and NiPt catalysts supported on SBA-15 were synthesized, characterized, and tested in anisole hydrodeoxygenation to determine the effect of the metal’s nature on the catalytic activity in the hydrogenation of the aromatic ring of anisole and hydrogenolysis of the C–O bond in the cyclohexyl methyl ether intermediate. Metal loadings in the catalysts were 5 wt% of Ni and 1 wt% of Pt. The bimetallic NiPt/SBA-15 catalyst showed the highest catalytic activity in both hydrogenation and hydrogenolysis, attributed to the promotional effect of Pt on NiO reduction and the formation of a Ni–Pt alloy with better dispersion of metal nanoparticles.

The rise of antimicrobial resistance has become a global threat in the recent years. With the rise in multidrug resistant organisms (MDRO), particularly the Carbapenem resistant organisms “difficult to treat” infections there is an urgent need for newer antibiotics. There are limited therapeutic options currently available, of which Ceftazidime avibactam (CZA) is a novel Beta lactam/ Beta lactamase inhibitor (BL/BLI) combination antibiotic. Avibactam is a non BL/BLI that binds reversibly to beta lactamase. The study aims to find the susceptibility of the novel Beta lactam- Beta lactamase combination drugs in carbapenem resistant & carbapenem sensitive isolates.1. To compare the susceptibility profile of CZA in Carbapenem resistant & carbapenem sensitive isolates of & ; 2. To compare the sensitivity of CZA with other group of antibiotics. This is a retrospective observational study from January 2022 to November 2023 done in the Department of Microbiology, Medanta Hospital, Lucknow. All the bacterial culture samples received during this period were subjected to routine identification and antibiotic susceptibility test on Vitek2 compact automated system. and isolates are included in the study group.: Of the Carbapenem Resistant isolates, , spp., spp. were 26.09% , 68.6% and 46.4% respectively. Amongst the carbapenem resistant(CR) isolates, CR (18.6%) is most susceptible to CZA than 9% CR & 3.2% CR . Of the Carbapanem sensitive isolates, sensitivity to CZA in (90.5%), (92.1%) & 87% in appeared to be much better than the other BL-BLI’s agents. The study suggests that CZA can be used as carbapenem sparing agent only in carbapenem sensitive pathogens. Also with the rise in resistance to the novel drug, it should be used judiciously and not as empiric therapy or an alternative to carbapenems. It may be useful in NDM carbapenemase producers if used synergistically with Aztreonam.

Published: June 2024

This study examined the firm characteristics of tax aggressiveness among quoted companies in Nigeria. The specific objectives were to determine the influence of firm size, profitability, liquidity and leverage on the tax aggressiveness of firms. It was an ex-post-facto and longitudinal study that spanned five years (2015-2019). The population consisted of 87 non-financial companies while the sample size was 67. The data used were from the financial statements and accounts of the sampled companies. The statistical techniques used include descriptive statistics, correlations and random and fixed effects panel least squares regression. The study showed that firm size and profitability have a significant influence and positive relationship with tax aggressiveness while liquidity has no significant influence on tax aggressiveness but has a positive relationship with it. Leverage had a significant influence while having a negative relationship with tax aggressiveness. It was concluded that firm characteristics are critical factors influencing tax aggressiveness among quoted companies in Nigeria. It recommended that a company's size should not be the basis for tax aggressiveness and that its profitability, liquidity and leverage position be disclosed in a way that accurately reflects its financial status. It will be of immense benefit to companies to ensure that their tax strategies align with ethical and legal standards and that they maintain transparency in their financial reporting. Similarly, the findings of this study have important implications for government tax authorities at both the federal and state levels in terms of the assessment of companies for tax purposes.

Published: June 2024

Background and Objectives: The main cause of mortality in burn patients is infection from burns. Drug-resistant bacteria are the main causes of wound infection, so alternative antibiotic therapies hold significant importance. The objective of this study was to examine the impact of a collagen hydrogel that contains a nanoemulsion of Lavandula essential oil on the heal- ing process of infected burn wounds.
Materials and Methods: In this experimental study, 20 rats were randomly divided after applying burns with a 10 mm diameter hot plate and infecting the wounds with multidrug-resistant Pseudomonas aeruginosa into four groups, including a positive control, a negative control, the first experiment (collagen hydrogel), and the second experiment (collagen hydrogel containing Lavandula essential oil nanoemulsion). On the 4th, 11th, and 18th days, tissue samples were taken for pathology studies. The important parameters in burn wound healing with hematoxylin and eosin and Masson's trichrome staining meth- ods were investigated and scored according to Abramov’s method.
Results: Based on the pathology findings, experimental groups 1 and 2 compared to the negative and positive control groups were effective in rat infection wound healing. The hydrogel scaffold in the experimental groups increased fibroblasts and an- giogenesis compared to the control groups. Epithelization was noticed only in the hydrogel group containing nanoemulsion.
Conclusion: The study findings suggest that the use of collagen hydrogel with Lavandula essential oil nanoemulsion has potential as a wound dressing. This is because it has the potential to effectively promote healing and act as an antibacterial agent to prevent infections.

Published: June 2024

Background: Recently, a number of papers have discussed the importance of evaluating service quality provided to customers. The purpose of this study is evaluating service quality of clinical diagnostic in Yazd Central Laboratory from customers’ point of views using the SERVQUAL and SERVPERF models in two simple and weighted types, and also, identifying the most suitable model for service quality evaluation.

Methods: The present research was applied research in terms of purpose and descriptive-analytical in terms of method. According to Morgan's table, the statistical sample of this research included 250 people who referred to Yazd central laboratory in September 2023; they were selected by simple random sampling method and a valid and reliable questionnaire with 33 items which was distributed among them. In the next step, to analyze the data collected from the questionnaire, SPSS 16 software was used to analyze Kolmogorov–Smirnov test, Student's t-test, analysis of variance, Fisher's Z test, and least squares method.

Results: The findings indicated that the expectations of service recipients are greater than their perceptions of the quality of the services received. The correlation coefficient between the overall satisfaction of the clients and the services and the level of service quality in the SERVPERF model (r = 0.7060) has a higher value than the weighted SERVPERF model (r = 0.6913), SERVQUAL model (r = 0.6890) and weighted SERVQUAL model (r = 0.6344). Moreover, the most valid models for measuring the quality of medical diagnosis services were respectively as follows: SERVPERF, weighted SERVPERF, SERVQUAL and weighted SERVQUAL.

Conclusion: Based on the research findings, it is recommended that managers consider the needs and demands of the clients in their future planning in order to improve the quality of services in medical diagnosis services, which are relatively more difficult to evaluate. Also, the level of standards required to provide health services in clinical diagnosis laboratories should be explained to the clients so that they have correct expectations and perceptions of the quality of services.
