For designing the electronic devices using molecular wires, it is important to understand the electronic properties at the molecular level. In this paper, the simulation methodology for analyzing the electrical conductivity of anthracene conjugated molecule sandwich between Au atoms via linker Sulfur atom, is proposed. This theoretical analysis is carried out for different applied electric field ranges from 0 to 0.26 VÅ-1 to metal electrode Au atom using density functional theory (DFT). The effect of external applied electric field towards the structural variation of metal attached anthracene molecule [WH] is well explored and compared the results with that of hetero atoms [N, S, and O] substituted heterocyclic systems [HAA, HTA and HOA]. Further, the ability of electron flow through these systems were explored from the analysis frontier molecular orbitals and density of states (DOS). The bonding nature of the studied molecules were well described from the QTAIM analysis and finally the reactive sites for electrophilic and nucleophilic attack was identified from the simulation of molecular electrostatic potential surface. Non-covalent interaction (NCI-RDG) analysis is addressed to characterize the interactions in heteroatom substituted anthracene based molecular nanowires. In our overall study, the outcomes are exposing that the significates feature and importance of electrical conductivity nature and transport characteristic of hetero-atoms (N, S, O) substituted anthracene based molecular nanowires.

The aim of this paper is parametric and reliability estimation for the two parameter length biased log-logistic distribution under squared error, generalized exponential, linear exponential and precautionary loss functions. Bayes estimates obtained under non informative priors through Lindleys approximation and through Markov Chain Monte Carlo are then compared with the classical parametric estimates. Bayesian risk analysis based on a simulated and a real data set are used to demonstrate application of the theoretic results.

193 DOI: 10.37398/JSR.2022.660121 Abstract: Brain functions are intricately linked to the proper functioning of the liver such that compromised liver function led buildup of neurotoxins, like ammonia, in the cerebral circulation is argued to derange brain functions in many ways. The neuronal damage during chronic liver failure (CLF) seems to be associated with oxidative stress and bioenergetic derangements. We have attempted to examine the level of oxidative stress markers and mitochondrial dysfunction in the hippocampus of the rats with CLF induced by administration of 100 mg/Kg bw thioacetamide (TAA).; ip. As compared to the control group rats, the CLF rats showed declined levels of the key antioxidant enzymes like superoxide dismutase, glutathione peroxidase and small molecule antioxidant glutathione in their hippocampus. This was consistent with the enhanced level of lipid peroxidation and protein carbonyl content. The significantly declined level of cellular ATP, the enhanced mitochondrial ROS level and release of mitochondrial cytochrome c in the hippocampus further suggested deranged mitochondrial function in this brain region of the CLF rats. The findings suggest imposition of oxidative stress and mitochondrial dysfunction in the hippocampus due to CLF in rats.

The current outbreak of the COVID-19 threatens public health worldwide, and WHO declares this as a global pandemic. Effective oral drug therapy against coronavirus did not discover yet. In order to find out an effective drug, we docked 23 compounds within the active site of 6LU7 protein of coronavirus. Among all, some antivirals exhibited very promising results against coronavirus and may be considered as a potential drug for treating COVID-19 disease. Molecular docking study revealed that isovitexin and apigenin found from nishinda (Vitex sp.) as well as our newly prepared compound (E)-4-((3,5-dibromo-2-hydroxybenzylidene)amino)-N-(5-methylisoxazol-3-yl)benzenesulfonamide showed exce-llent activity as compared to danoprevir, lopinavir, remdesivir and ritonavir. Isovitexin showed a binding affinity of -8.00 kcal/mol, whereas the binding affinity of sulfonamide compound with the coronavirus protein was -7.30 kcal/mol, which was relatively high compared to other antiviral drugs. Besides, the synthesized sulfonamide compound's absorption, distribution, metabolism, excretion, and toxicity profiles were also carried out. The compound showed excellent drug-like properties and percentage of human oral absorption. Moreover, it was found to be safe for the human body in toxicological risk assessment.

Through this paper, the exponentiation transformation has been applied to a version of the Unit Lindley distribution having support on (0, 1). The graphical behaviour of the density curve for different values of the parameters is studied and various statistical properties of the distribution such as descriptive statistics, generating functions, reliability properties, distributions of the order statistics are discussed. Random numbers from the proposed distribution are generated and a simulation study is performed to assess the behaviour of the parameter estimates on the basis of the generated sample. The parameters of the distribution are estimated using the maximum likelihood method. Finally, the utility of the developed model is exhibited through an original data set on timing of infant deaths.

Piezo actuation of mechanical resonators is widely adapted because of its simplicity and versatility. Piezo-driven atomic force microscopy cantilevers in air or liquid have a substantial drawback in that they produce spurious resonances that conceal the cantilever resonance peak. Bulk acoustic wave propagation via the piezo-shaker and device substrate causes these undesired peaks. Such restrictions of piezo actuation are rarely reported in nanomechanical resonant sensing. Because most NEMS (nanoelectromechanical systems) experiments are carried out at low pressure to achieve a higher quality factor ) and hence increased sensitivity, spurious resonances are frequently overlooked due to their insignificance. However, this piezo-driven issue may affect NEMS responses at higher pressures (lower Q) and must be addressed carefully. This study reveals spurious resonances from high vacuum to the atmosphere while investigating piezo-driven nanoscale doubly clamped beam responses. At all pressures, spurious peaks with a characteristic frequency span independent of air damping exist, and at higher pressures, they squeeze the mechanical peak. Such squeezing provides a larger derived from the driven phase responses by order of magnitude than the mechanical computed from the measured thermal noise spectra. Interestingly, the characteristic frequency span, not air damping, is revealed to dominate driven .

Maintaining the security of data stored in the public or private cloud is a more tedious task. The cloud is the only arrangement for storing enormous amounts of data, but there is a possibility of storing the same data more than once. The traditional security system generates different unreadable data for the same readable content of a file. Therefore, it is necessary to address data security of the cloud and duplication in cloud storage. This paper concentrates on developing a data security and deduplication framework with different security techniques and mechanisms to address the said difficulties in the cloud. The framework proposed in this paper focuses on reducing security vulnerability as well as data duplication. The paper describes the components used in the frameworks. The main research contribution of the framework is having enhanced the convergent encryption technique, key generation techniques, and deduplication mechanism for maintaining a single copy of data in the cloud. The proposed framework’s efficiency is measured by implementing the work by developing a cloud-based application that coded for all the procedures of the proposed framework and tested in the cloud environment.

These polycyclic high-grade rocks include several blocks bounded by faults in the northern margin and a prominent shear zone towards the western margin. Recent imputes made in the EGMB proclaim various smaller domains characterized by their distinct tectono-metamorphic evolutions. However, the correlation made between the various metamorphic and tectonic events with respect to their geochronologic ages still lack solid results. As such, we contemplate to impart an overview based on the observations made from the available isotopic data of the Eastern Ghats Mobile Belt.

In this manuscript, Markovian queueing system with working vacation, Bernoulli schedule interruption, setup time under feedback, reneging of impatient customers, and retention of reneged customers are analyzed. The unsatisfied customers on service completion may either leave the system with probabilities or may rejoin the queue with complementary probabilities during working vacations and regular service, respectively. The waiting customers in the queue may lose patience due to vacations and decide to leave without getting the service with probability q. They may be retained in the system via some convincing mechanisms with probability (1-q). The mean system length, probability of server in various states, mean sojourn time are obtained using the probability generating function method. The MATLAB software is used for representing the observed behavior graphically.

The changes in land use/land cover can potentially impact the land surface temperature. The land-use features that are impenetrable can increase the Land Surface Temperature, while vegetation cover can decrease the Land Surface Temperature. In this study, we examined the Rajkot city in Saurashtra, Gujarat concerning changes in land use and temperature. Here, we used the imageries from Landsat for the years 2000, 2010, and 2020. We also analyzed the Land Surface Temperature to see how the changes in Land Use Land Cover influence the Land Surface Temperature of the city. We found that across three decades, the city's barren land and fallow land have been decreased and settlement, wetlands, vegetation cover, and industrial areas have been increased. Subsequently, the changes in Land Surface Temperature were noticed. The Land Surface Temperature decreased in the regions where barren land and fallow land are decreased while Land Surface Temperature increased in the areas where wetlands and vegetation cover increased. We conclude that the replacement of the barren and fallow land with human settlement and vegetation cover can decrease the Land Surface Temperature at the local scale.
