Paving New Roads Using Allium sativum as a Repurposed Drug and Analyzing its Antiviral Action Using Artificial Intelligence Technology

Context The whole universe is facing a coronavirus catastrophe, and prompt treatment for the health crisis is primarily significant. The primary way to improve health conditions in this battle is to boost our immunity and alter our diet patterns. A common bulb veggie used to flavor cuisine is garlic. Compounds in the plant that are physiologically active are present, contributing to its pharmacological characteristics. Among several food items with nutritional value and immunity improvement, garlic stood predominant and more resourceful natural antibiotic with a broad spectrum of antiviral potency against diverse viruses. However, earlier reports have depicted its efficacy in the treatment of a variety of viral illnesses. Nonetheless, there is no information on its antiviral activities and underlying molecular mechanisms. Objectives The bioactive compounds in garlic include organosulfur (allicin and alliin) and flavonoid (quercetin) compounds. These compounds have shown immunomodulatory effects and inhibited attachment of coronavirus to the angiotensin-converting enzyme 2 (ACE2) receptor and the Mpro of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2). Further, we have discussed the contradictory impacts of garlic used as a preventive measure against the novel coronavirus. Method The GC/MS analysis revealed 18 active chemicals, including 17 organosulfur compounds in garlic. Using the molecular docking technique, we report for the first time the inhibitory effect of the under-consideration compounds on the host receptor ACE2 protein in the human body, providing a crucial foundation for understanding individual compound coronavirus resistance on the main protease protein of SARS-CoV-2. Allyl disulfide and allyl trisulfide, which make up the majority of the compounds in garlic, exhibit the most potent activity. Results Conventional medicine has proven its efficiency from ancient times. Currently, our article's prime spotlight was on the activity of Allium sativum on the relegation of viral load and further highlighted artificial intelligence technology to study the attachment of the allicin compound to the SARS-CoV-2 receptor to reveal its efficacy. Conclusions The COVID-19 pandemic has triggered interest among researchers to conduct future research on molecular docking with clinical trials before releasing salutary remedies against the deadly malady.
VLBI observations of SN 1986J - deviations from spherical symmetry in its radio brightness distribution

The 1987.4 radio brightness distribution at 5 GHz of the unusual supernova SN 1986J can be described by an elliptical Gaussian model with a half-width at half-maximum of the major axis of 0.80 + or - 0.12 mas and a ratio between the minor axis and the major axis of 0.62 + or - 0.12. This result could be due to an anisotropic flow pattern of the expanding gas and/or to peculiar variations of the brightness across the emission region. We discuss the implications of these possibilities for the understanding of the explosion process, the density distribution of the ambient medium, and the brightness distribution of a possible pulsar nebula. 33 references.
Dynamic User Recruitment in Edge-Aided Mobile Crowdsensing

Most of the existing user recruitment methods are designed for the two-tier structure. However, the computational consumption of the cloud platform rises rapidly as data volumes increase. In recent years, edge computing has been introduced into mobile crowdsensing. In this article, we study dynamic user recruitment with edge-aided mobile crowdsensing. Specifically, we consider the scenarios for different sensing tasks. One is the long-duration task, and the other is the short-duration task. For the former, it is time-insensitive, while the latter is time-sensitive. In the scenario with the long-duration task, we consider a simple offline scenario and propose an Edge-Node User Recruitment (ENUR) algorithm to recruit users statically. Then, we consider the online scenario and propose a Budget Re-Distribution algorithm for Edge Nodes User Recruitment (BRD-ENUR). It dynamically redistributes the budget according to the task completion ratio of different edge nodes. In the scenario with the short-duration task, the whole sensing process consists of multiple rounds. In each round, edge nodes need to recruit users between selected users (exploitation) and unselected users (exploration) under the budget. We model such a user recruitment process as a novel combinatorial multi-armed bandit problem. Then, we propose an Edge Nodes User Recruitment algorithm based on combinatorial Multi-armed Bandit (EN-URMB). Extensive experiments show the validity and reliability of our user recruitment algorithms based on the real data set.
HF‐induced airglow at magnetic zenith: Thermal and parametric instabilities near electron gyroharmonics

We analyze airglow induced by intense radio waves at the High‐frequency Active Auroral Research Program (HAARP) facility for pump frequencies f0 near the second and third electron gyroharmonic (fc). While passing through the double resonance in the weakening ionosphere during heating at f0 ∼ 2fc, airglow intensities rose abruptly and remained elevated during four consecutive pulses. During this period both the thermal and parametric instabilities coexisted. Subsequently, the thermal parametric instability was hampered. The effectiveness of heating near the second gyroharmonic is ascribed to specific dispersion characteristics near the double resonance. The observations suggest that Langmuir waves participate in cyclotron acceleration when the local plasma and second gyroharmonic frequencies match. With f0 ∼ 3fc the airglow terminated due to the suppression of cyclotron acceleration and parametric decay instability.
Graphene-Based Coating to Mitigate Biofilm Development in Marine Environments

Due to its several economic and ecological consequences, biofouling is a widely recognized concern in the marine sector. The search for non-biocide-release antifouling coatings has been on the rise, with carbon-nanocoated surfaces showing promising activity. This work aimed to study the impact of pristine graphene nanoplatelets (GNP) on biofilm development through the representative marine bacteria Cobetia marina and to investigate the antibacterial mechanisms of action of this material. For this purpose, a flow cytometric analysis was performed and a GNP/polydimethylsiloxane (PDMS) surface containing 5 wt% GNP (G5/PDMS) was produced, characterized, and assessed regarding its biofilm mitigation potential over 42 days in controlled hydrodynamic conditions that mimic marine environments. Flow cytometry revealed membrane damage, greater metabolic activity, and endogenous reactive oxygen species (ROS) production by C. marina when exposed to GNP 5% (w/v) for 24 h. In addition, C. marina biofilms formed on G5/PDMS showed consistently lower cell count and thickness (up to 43% reductions) than PDMS. Biofilm architecture analysis indicated that mature biofilms developed on the graphene-based surface had fewer empty spaces (34% reduction) and reduced biovolume (25% reduction) compared to PDMS. Overall, the GNP-based surface inhibited C. marina biofilm development, showing promising potential as a marine antifouling coating.

The Synthesis of Nonuniform Lines of Finite Length-Part I

The class of lossless, nonuniform transmission lines having an absolutely continuous characteristic impedance is considered. It is shown that an integral representation for the solution of such a line is possible when the line is terminated in a matched load. The principal contribution of this paper is the derivation of a linear integral equation in the kernel function of this representation. It is shown that the solution to this integral equation constitutes a unique solution to the synthesis problem for lines of the class considered. Necessary and sufficient conditions for realizability are also given.

Negative refraction in periodic and random photonic crystals

We present a theory of the artificial magnetic activity in a two-dimensional (2D) dielectric photonic crystal. We show, by using a multiple-scale approach, that if the rods constituting the crystal have Mie resonances at large enough wavelengths, the crystal can be characterized by an effective permeability exhibiting anomalous dispersion. The theoretical results are checked numerically for periodic and random photonic crystals.
Platelet indices in critically ill septic patients as a predictor of mortality

ABSTRACT Background Platelet (PLT) indices are used to quantify the total number of PLTs, their morphology, and their proliferation kinetics. The aim of this work was to explore whether platelet indices (PLT count, platelet distribution width (PDW), mean platelet volume (MPV) and platelet crit (PCT) can be used to predict mortality in critically ill septic patients. Methods This prospective cross-sectional study was carried out on 54 critically ill septic patients according to sequential organ failure assessment (SOFA) scores from May 2020 to May 2021. Patients were grouped into: (1) survivors’ group and (2) non-survivors’ group. Complete blood count, C-reactive protein (CRP) and procalcitonin serum levels were measured. Results A rise in MPV, PDW, procalcitonin and CRP and a fall in PLT and PCT was associated with non-survivors’ group. For prediction of mortality, PLT, MPV and PDW at cut-off value ≤183 *103/dl, >10.9 fl and >14% had (57.89%, 84.21% and 78.95%) sensitivity, (71.43%, 80% and 74.29%) specificity, (52.4%, 69.6% and 62.5%) positive predictive value (PPV), negative predictive value (NPV) (75.8%, 90.3% and 86.7%), (0.672, 0.868 and 0.856) area under the curve (AUC) and (0.038, <0.001 and <0.001) P value respectively. For prediction of mortality, procalcitonin at cut-off value 5.6 ng/dl had 94.74% sensitivity, 85.7% specificity, 78.3% PPV, NPV 96.8, 0.919 AUC and <0.001 P value. In multivariate regression analysis, most affecting factors for mortality were procalcitonin, MPV and PDW (P value<0.05). Conclusions Platelet indices are low-cost, readily accessible metrics that have the potential to be valuable prognostic markers in sepsis.
Organizational Fit and Performance in Miles and Snow’s Configurational Theory: A Covariant Analysis

Miles and Snow’s (1978) model posits that organizational performance is dependent upon the degree of consistency (fit) that managers establish between organizational and environmental elements. However, different interpretations of the concept of fit coexist in the literature. We argue that in this model, consistency can be defined as a pattern of “equivalent covariance”, which is operatively created through the use of confirmatory factor analysis. The form of fit as covariance leads to the view of “configuration as quality”, in that the basic subject is the study of the interrelationships among organizational and environmental elements. The concept of fit as covariance is decidedly different from the traditional concept of fit as difference, which regards configuration as a typology or taxonomy. The covariance perspective of configurational theory is underused; for this reason, we apply this analytical perspective to a sample of 229 companies. The empirical results confirm that consistency positively influences organizational performance.
A p–n Junction by Coupling Amine-Enriched Brookite–TiO2 Nanorods with CuxS Nanoparticles for Improved Photocatalytic CO2 Reduction

Photocatalytic CO2 reduction is a promising technology for reaching the aim of “carbon peaking and carbon neutrality”, and it is crucial to design efficient photocatalysts with a rational surface and interface tailoring. Considering that amine modification on the surface of the photocatalyst could offer a favorable impact on the adsorption and activation of CO2, in this work, amine-modified brookite TiO2 nanorods (NH2-B-TiO2) coupled with CuxS (NH2-B-TiO2-CuxS) were effectively fabricated via a facile refluxing method. The formation of a p–n junction at the interface between the NH2-B-TiO2 and the CuxS could facilitate the separation and transfer of photogenerated carriers. Consequently, under light irradiation for 4 h, when the CuxS content is 16%, the maximum performance for conversion of CO2 to CH4 reaches at a rate of 3.34 μmol g−1 h−1 in the NH2-B-TiO2-CuxS composite, which is approximately 4 times greater than that of pure NH2-B-TiO2. It is hoped that this work could deliver an approach to construct an amine-enriched p–n junction for efficient CO2 photoreduction.
The NGC 6426 RR Lyrae Variables and Horizontal-Branch Morphology

We present BVRI CCD photometry for 12 RR Lyrae variables, including three newly discovered ones in the Oosterhoff type II globular cluster NGC 6426. New light curves and ephemerides are presented. The mean periods of the RRab and RRc variables whose light curves are analyzed in this work are ⟨Pab⟩ = 0.70 ± 0.02 days and ⟨Pc⟩ = 0.34 ± 0.03 days, respectively. The number ratio of the RRc type variables to the total number of RR Lyrae type variables is n(c)/n(ab + c) = 0.36. The period-amplitude relation for fundamental-mode RR Lyrae variables (RRab) in NGC 6426 supports the recent conclusion of Clement & Shelton that this relation is not a function of metal abundance. Fourier decomposition of the light curves has been used to determine the mass, luminosity, and temperature for the RRc stars. Application of the formula of Jurcsik & Kovács, which relates Fourier parameters of RRab stars to [Fe/H], yielded the value [Fe/H]= -2.16 ± 0.13 dex, which is compatible (given the errors) with the value -2.33 ± 0.15 dex, derived from the red giant branch color index developed by Hatzidimitriou et al. From star counts along the horizontal branch (HB), we obtain the Lee et al. HB color distribution index, (B-R)/(B+V+R) = 0.58 ± 0.18. The HB of NGC 6426 resembles that of NGC 5053 and M68. We find almost no faint blue stars analogous to the ones constituting the extended HB in M15.
Modelling Rayleigh–Taylor instability of a sedimenting suspension of several thousand circular particles in a direct numerical simulation

In this paper we study the sedimentation of several thousand circular particles in two dimensions using the method of distributed Lagrange multipliers for solid–liquid flow. The simulation gives rise to fingering which resembles Rayleigh–Taylor instabilities. The waves have a well-defined wavelength and growth rate which can be modelled as a conventional Rayleigh–Taylor instability of heavy fluid above light. The heavy fluid is modelled as a composite solid–liquid fluid with an effective composite density and viscosity. Surface tension cannot enter this problem and the characteristic shortwave instability is regularized by the viscosity of the solid–liquid dispersion. The dynamics of the Rayleigh–Taylor instability are studied using viscous potential flow, generalizing work of Joseph, Belanger & Beavers (1999) to a rectangular domain bounded by solid walls; an exact solution is obtained.
Noncontinuity of spectrum for the adjoint of an operator

This paper deals with the connection between continuity of spectrum at an element T of the Banach algebra of all bounded linear operators on a Banach space X and at the adjoint T* of T. In particular, we show that, if X is not reflexive, the spectrum function may be continuous at T and discontinuous at T*.
Salix alba phytoremediation potential of heavy metals

There are 4 categories of interactions of plants with heavy metals: exclusion, accumulative, indicator, and hyperacumulative plants (ability of plants to accumulate more than 100 times the amount of metals). Because the most ecological problems are associated with water and soil pollution with heavy metals/metalloids, the use of plants to transfer toxins from the environment, is one of the most important strategies for preserving natural ecological balance. Heavy metals from the soil to plants get over few processes, such as redox reactions, ionic exchange, precipitation-dissolution, etc. The use of plants to make toxic soil components into non-toxic is called phytoremediation, but in the literature, we can also find such terms as bioremediation, botanical bioremediation and green remediation (Chaney et al., 1997). This is a friendly and efficient natural process by which pollutants are transferred and removed from water, soil and air by plants and organisms that live with them (e.g. microorganisms) and was first introduced in the 1980 by Chaney, and since then it is used to remove heavy metals from the environment. Plants that accumulate metals in large quantities (hyper accumulators) have enormous capability for their use in the remediation of environment from metals. Two significant characteristics of hyperaccumulating metal plants are that they must be tolerant to high concentrations of metals in root and shoots cells and must have potential to uptake these elements quickly and at high levels from the soil. A large number of woody species have been studied or used in phytoremediation and major attention is paid to fast-growing species as genera willow (Salix spp.), poplar (Populus spp.), etc. Willow trees have large, spreading roots and invasive growth, which increase their utilization and use as in situ phytoextractor (Mertens et al., 2006). Willows are appropriate as phytoextractors with excessive mobility of heavy metals to the shoots and biomass production, due to their high element accumulation (Greger and Landberg, 1999). The potential of the genus Salix to accumulate large quantities of toxic metals/metalloids has been proven, particularly for cadmium (Klang-Westin and Eriksson, 2003). Significant differences in metal uptake have been identified between willow types and clones (Vysloužilová et al., 2003). Heavy metal/metalloids concentrations in Salix spp. diverse between plant parts and species, in particular arsenic concentration lowered in the following order: leaves > branch bark > stem bark > wood and cadmium concentration in this sequence: leaves > wood = roots (Tlustoš et al., 2007). Willows' resistance to elements such as lead, cadmium, nickel, copper, iron and zinc as well as their capacity to absorb large quantities of metals in their tissues have been demonstrated, implying that they may be used for metal extraction (Keller et al., 2003). This research presents the metal accumulation potential of Salix alba from the soil to plant, expressing also the correlation between them.
