1. Mahato, R., Das, M., and Sibanda, P., (2021), Hall Effect on MHD Transient Free Convection Flow Of Chemically Reactive Casson Fluid with Heat Source/Sink Past an Infinite Vertical Cylinder. Physica Scripta, Vol. 96, No. 1, pp. 015207.

Abstract: This article presents the effect of Hall current, magnetic field, and chemical reaction on an unsteady MHD transient free convective Casson fluid flow past an infinite vertical cylinder subject to heat source and sink. Closed-form solutions are obtained by employing Laplace transform and inverted using Mellin-Fourier-Integral and presented them in terms of Bessel functions. The influence of different physical parameters on fluid flow is discussed via graphs and tables. By upgrading values of the Prandtl number reduces the temperature but enhances the Nusselt number. This fluid flow model will be applicable in geophysics, the mining industry, chemical and biomedical engineering.

2. Sen S. S. S., Das M, and Shaw S. (2021), Thermal Dispersed Homogeneous-Heterogeneous Reaction Within Mhdflowof Jeffrey Fluid in the Presence of Newtonian Cooling and Nonlinear Thermal Radiation, Heat Transfer, pp.1–16,

Abstract: The current work studies the effects of Newtonian cooling, magnetic field and non-linear radiation on the Jeffrey fluid flow along with thermal dispersion and homogeneous-heterogeneous reaction. BVP4C solver of MATLAB has been used to solve the governing equations. The variation in the fluid flow due to different parameters has been analyzed through graphs and tables. Some important observations of this work are that the fluid velocity declines with an increase in melting parameter and magnetic number whereas the fluid temperature increases with radiation parameter. The present model can be utilized by plastic and food processing industries to enhance their productivity.

Abstract: This work focuses on the synthesis and characterization of a Pb-free (0.8-x)Na0.5Bi0.5TiO3-0.2SrTiO3-xBiFeO3, 0.00≤ x≤ 0.10 perovskite. The ceramics exhibit significant improvement in some of the key parameters like Tc, dielectric constant, temperature stability, TCe values, etc. The composition (x=0.05) showed a permittivity of ~4000 at 100 kHz at 250 °C with a normalized permittivity Δe/e250 varying not more than ±15% from 200 °C to beyond 500 °C. In addition, the same composition yields a TCε value as low as -194 ppm/°C which is promising from the capacitor application point of view.

Abstract: Controlled synthesis pure-phase Bi0.98Tb0.02Fe1−xCoxO3 (BTFCO, x = 0.01, 0.03, 0.05 and 0.07) nanoparticles with rhombohedral structure using a facile sol–gel method opens the doors to robust their magnetic and photocatalytic properties significantly. The as-synthesized samples are highly effective for rhodamin B (RhB) degradation under visible light irradiation. Bi0.98Tb0.02Fe0.93Co0.07O3 nanoparticles exhibit the best photocatalytic activity owing to their larger specific surface area, lower band gap, and reduced average particle size. Besides, 1.2% efficiency retention for the degradation of RhB dye using BTFCO7 after the 20th cycle suggests a potential candidate to address the current scenario in the environmental remediation technology.

Abstract: The Authors have used the Weather Research and Forecasting (WRF) model to understand the impact of microphysical parameterization schemes on the track and intensity of extremely severe cyclonic storm (ESCS) ‘‘Fani’’ that occurred during 26 April to 4 May 2019 in the Bay of Bengal. The rainfall forecasts and TRMM observations were analyzed for quantification / spatial matching using the Method for Object-Based Diagnostic Evaluation (MODE) tool. Analysis of the simulated latent heat flux in different microphysics schemes suggests that the latent heat flux release at VSCS intensity level or above contributes to further intensification of the Tropical Cyclone.

7. Giri, R. L., Nanda, A. K., Dasgupta, M.,Misra, S. K. , and Bhattacharjee, S.(2021)On Ageing Intensity Function of Some Weibull Models,Communications in Statistics—Theory and Methods,

ABSTRACT: There are many measures for qualitative and quantitative analysis of ageing phenomena of a system with a well defined statistical distribution, namely, hazard rate, ageing intensity (AI) function etc. The extensive usage of Weibull distributions in various fields has prompted us to explore the ageing property of these models. The present work derives the AI function of recent continuous Weibull distributions. In the process, we obtain generalizations of a few recent Weibull models. As noted, the characteristics of a distribution described by hazard rate and ageing intensity function differ altogether in many cases. Some of the results presented in this work have been analyzed through a simulation study using R software.

Smart pH and thermoresponsive microgel particles are used as microreactors to prepare hybrids of gold (Au) and silver (Ag) nanoparticles using a facile two steps in situ approach. These bimetallic smart hybrid microgels exhibit excellent tunable catalytic activity in the reduction of 4-nitrophenol (4-NP)-to-4-aminophenol (4-AP) in the presence of sodium borohydride. These responsive hybrid particles can be a good replacement for natural enzymes as biocatalyst. These hybrids can be also used in other applications such as photothermal drug-delivery and antimicrobial studies.

DOI: (IF 4.303)

Amidst the exponentially growing world economy, textile industries are referred to as one of the largest contributors to the economic growth and also the biggest pollution causing production sector. The conventional methodologies for waste effluent treatment involves huge energy, time, infrastructure, material, land, manpower, and capital consumption. The presented report consists of a detailed assessment of literature review depicting the classical processes and technological innovations in the latest few decades for the degradation and abatement of dyes and other pollutants from textile waste-effluents with a proposal of a novel economic and eco-friendly cutting-edge technology.

The polyphagous spotted pod borer, Maruca vitrata is an important agricultural pest that causes extensive damage on various food crops. Though the pest is managed by synthetic chemicals, exploration of biotechnological approaches for its control is important. RNAi-based gene silencing is one such tool that has been extensively used for functional genomics and is highly variable in insects. In view of this, we have attempted to demonstrate RNAi in M. vitrata through exogenous double-stranded RNA (dsRNA) administration targeting seven genes associated with midgut, chemosensory, cell signalling and development.

Concurrent use of DNA damaging agents with PARP inhibitors contribute to the effectiveness of the anticancer therapy. But there is a dearth of reports on the antiangiogenic effects of PARP inhibitors and the suppression of angiogenesis by this drug combination is not yet reported. For the successful development of cancer therapeutics, anti-cancer drugs ought to have anti-angiogenic potentiality along with their DNA damaging abilities. In this current piece of work, we investigated the in vitro and in ovo anti-angiogenic effect of Curcumin and Veliparib (a PARP inhibitor) in oral cancer.

Quinacrine (QC) is a tricyclic compound and a derivative of 9-aminoacridine. It has been widely used to treat malaria and other parasitic diseases since the last century. Interestingly, studies have revealed that it also displays anti-cancer activities. Here, we have discussed the anti-cancer mechanism of QC along with its potentiality to specifically target cancer stem cells.

5-Fluorouracil (5-FU) has been an important anti-cancer drug to date. With an increase in the knowledge of its mechanism of action, various treatment modalities have been developed over the past few decades to increase its anti-cancer activity. But drug resistance has greatly affected the clinical use of 5-FU. Overcoming this chemoresistance is a challenge due to the presence of cancer stem cells like cells, cancer recurrence, metastasis, and angiogenesis. In this review, we have systematically discussed the mechanism of 5-FU resistance and advent strategies to increase the sensitivity of 5-FU therapy including resistance reversal. Special emphasis has been given to the cancer stem cells (CSCs) mediated 5-FU chemoresistance and its reversal process by different approaches including the DNA repair inhibition process.

Epub 2021 Mar 8.

Tumor associated macrophages in the tumor microenvironment secrete multiple cytokines, which regulate cancer cells growth and invasiveness. We systematically studied the role of cytokines in the induction of cancer stem like cells (CSCs) in oral cancer cells niche and evaluated the mechanism of Resveratrol nanoparticle (Res-Nano) mediated-reduction of CSCs properties in cells. A highly M1-like macrophages-enriched conditioned medium (CM) was generated by treating fixed doses of PMA and LPS in THP-1 cells alone as well as co-cultured of H-357 plus THP-1 cells. These M1-like macrophages increased the production of cytokines (e.g., TNF-α, IL-6, IL-1β, etc.). A CSCs populated environment was created after addition of cytokine-enriched-CM of co-culture of H-357 and THP-1 cells to cancer cells and cytokine enriched CM of THP-1 cells to patient derived primary oral cancer cells, respectively. After incubation with CM, enhancement of stemness, angiogenic and metastatic properties of both H-357 and primary oral cancer cells were noted. Res-NP decreased the cytokines level in CSCs-enriched cells and reduced the invasion, proliferation and growth of CSCs. Representative metastatic (CD133, ALDH1, CXCR4, etc.) and angiogenic markers (MMPs, iNOS, VEGF-A, etc.) were decreased after Res-NP treatment in CSCs enriched oral cancer cells niche. It also disrupted angiogenesis, depleted nitric oxide production in fertilized chick embryos and reduced the expression of metastatic and angiogenic markers in xenograft mice model system. Thus, this study concluded that CSCs-mediated stemness is a cytokine dependent phenomena and treatment of Res-NP inhibit this process in in vitro, in vivo and ex vivo systems.

(2021), Is Upregulation of Sarcolipin (SLN) Beneficial or Detrimental to Muscle Function? Frontiers in Physiology, DOI: 10.3389/fphys.2021.633058.  (IF 12.66)

Sarcolipin (SLN) contribute to muscle nonshivering thermogenesis and energy metabolism. However, SLN expression in various muscle pathophysiology has not been studied in details although its expression is several folds higher during muscle development. Here, we critically examined whether SLN upregulation in the skeletal muscle is a cause or compensatory response. We show that SLN levels are induced in muscle during systemic bacterial (Salmonella) infection or lipopolysaccharides (LPS) treatment. SLN expression is significantly upregulated in different types of muscular dystrophies and myotubular myopathy. Our data suggest increased SLN expression is a compensatory response to meet the higher energy demand of muscle.

Abstract: Genetically engineered mouse models have been used to determine the role of sarcolipin (SLN). However, few studies had difficulty in detecting SLN in FBV/N mice and questioned its relevance to muscle metabolism. Therefore, here we compared the expression of SLN and key proteins involved in Ca2+-handling and mitochondrial metabolism between FVB/N and C57BL/6J mouse strains. Data suggests that, SLN expression is less abundant in the skeletal muscles of FVB/N mice compared to C57BL/6J strain. Further, differential expression of Ca2+-transporters and the electron transport proteins in the mitochondria was observed which may contribute to differences in energy metabolism.

Aurora kinase B (AURKB) plays a pivotal role in the regulation of mitosis and is gaining prominence as a therapeutic target in cancers; however, the role of AURKB in retinoblastoma (RB) has not been studied. The expression of AURKB was found elevated in human RB tissues, and the overexpression significantly correlated with optic nerve and anterior chamber invasion. Targeting AURKB with small-molecule inhibitors and shRNAs resulted in reduced cell survival and increased apoptosis and cell cycle arrest at the G2/M phase. More importantly, primary RB specimens showed decreased cell viability in response to pharmacological AURKB inhibition. Additional studies have demonstrated that the MYCN oncogene regulates the expression of AURKB in RB.

Antibacterial activity of silver nanoparticles is often associated with toxicity to the host. We here report that noncytotoxic doses of silver nanoparticles coated with zinc oxide, [email protected], can stimulate proliferation and migration of human keratinocytes, HaCaT, with increased expression of Ki67 and vinculin at the leading edge of wounds. Interestingly, [email protected] stimulates keratinocytes to produce the antimicrobial peptides hBD2 and RNase7, promoting antibacterial activity against both extracellular and intracellular Staphylococcus aureus isolated from wounds. Overall, these results suggest that [email protected] has the potential to significantly improve treatment outcomes in clearing wound infection.

Inteins are intervening polypeptides that interrupt the functional domains of several important proteins across the three domains of life. Inteins excise themselves from the precursor protein, ligating concomitant extein residues in a process called protein splicing. Post-translational auto-removal of inteins remain critical for the generation of active proteins. The perspective of inteins in science is a robust field of research, however fundamental studies centralized upon splicing regulatory mechanism are imperative for addressing more intricate issues.

The way the teachers deliver the content of any course curriculum is always important. It must create enough interest in the students, especially when it is in the online mode. In this paper, a novel pedagogy has been proposed, which can work for both online and offline classes based on the social constructivist methods. The methods followed in the proposed pedagogy are classified into two types: social examples and technical drama. One of the courses of first-year engineering undergraduates, Basic Electrical Engineering (BEE), has been taken into consideration for the practical implementation of this pedagogy.

In this paper, basic cell of a novel switched capacitor converter (SCC) has been proposed first. After that, the generalized structure of proposed SCC is developed. A switched capacitor multilevel inverter (SCMLI) utilizing 2 number of generalized SCCs is developed next. Further, cascaded extension of proposed SCMLI is realized and analyzed for symmetric and asymmetric dc source configurations. An extensive comparison study shows that the proposed SCMLI requires lower number of components as compared to other SCMLIs.  Extensive experimental results are presented to validate the merits of the proposed structure.

ABSTRACT: In industrial unstable processes, disturbance rejection is more challenging task than set point tracking. So, cascade control structure is widely used in many chemical processes to reject disturbances. In this work, an advanced dead time compensator based series cascade control structure (SCCS) is suggested for unstable processes. The suggested SCCS has three controllers (named as primary, secondary and stabilizing controllers). Both primary and secondary controllers are designed using fractional order based internal model control (IMC) approach. Optimal values of the closed-loop time constants and fractional orders of IMC filters are obtained using constrained artificial bee colony (ABC) algorithm.

Keywords: Fractional calculus, IMC, ABC algorithm, Series cascade control, Dead time compensator.

ABSTRACT: ULP- SOI transistor are still suffering from SCEs, the FBE and SHEs. The leakage current is minimized by using GaP and buried oxide layer (SiO2-Si3N4-SiO2) in 30 nm channel node SOI MOSFET. The high thermal conductivity HfO2 and Si3N4 material being applied in the mentioned structure to reduce the maximum temperature and controls self-heating effects. Also, the extra floated holes in the active region is reduced by a new N+-P+ diode created at the interface of the N+ source region and P+ silicon layer resulting in control FBE. The parameters like SS, gm, Ion/Ioff ratio, Vth, DIBL of an SOI MOSFET are also studied. Extracted numerical outcomes make an evidence to replace conventional SOI by the modified structure.

AEU – International Journal of Electronics and Communications, Vol.129, No. 153549.

ABSTRACT:This manuscript presents an UWB-BPF with dual TZ embedded in the passband. Based on the vertical EM coupling of microstrip-to-CPW transition, the structure has two similar microstrips placed adjacent on the top plane whereas a short-circuited CPW forms the ground. The response of this BPF is quasi-elliptical in nature with two TZs at either passband edges which enhances selectivity and improves insertion/return loss. To this basic BPF, novel sectoral folded split ring resonator (SFSRR) and spiral resonator (SR) are appended in the slots of the ground plane, which produce dual TZs in the passband at 4.5 and 8 GHz respectively.

ABSTRACT: Sudden cardiac death (SCD) is a major cause of death among patients with heart diseases that occurs mainly due to ventricular tachyarrhythmia (VTA). The main challenging task is to predict the VTA condition at a faster rate for timely application of automatic external defibrillator (AED) in order to save lives. Deep neural network (DNN) has been used for VF/VT classification in hybrid time–frequency-based features, which were decomposed with the wavelet transform, empirical mode decomposition (EMD), and variable mode decomposition (VMD) approaches.

ABSTRACT: Brain stroke occurs mainly due to insufficient blood flow to the brain.  The affected part of brain will not function properly after this attack. Hence, early detection is important for more efficacious treatment. Computer-aided diagnosis can help in detecting life-threatening disease in its early stage by utilizing image processing and soft computing techniques. A model was developed to assess intracerebral haemorrhage by employing non-linear features combined with a probabilistic neural network classifier in CT images. Our model achieved a maximum accuracy of 97.37% in discerning normal versus haemorrhagic subjects. An intracerebral haemorrhage index is also developed using only three significant features.

ABSTRACTThe load frequency control (LFC) and tie-line power are the key deciding factors to evaluate the performance of a multiarea power system. In this paper, the performance analysis of a two-area power system is presented. This analysis is based on two performance metrics: LFC and tie line power. The performance is evaluated by designing a proportional plus integral (PI) controller. The hybrid gravitational search with firefly algorithm (hGFA) has been devised to achieve proper tuning of the controller parameter. The performance is compared with some of the well-known optimization techniques, namely, particle swarm optimization, genetic algorithm, gravitational search algorithm and the firefly algorithm.

ABSTRACT: Energy consumption in WSN that involves multiple sensor nodes is a crucial parameter in many applications. Hence, an energy-efficient cluster-head selection strategy is imperative in a WSN to improve network performance. So to balance the harsh conditions in the network with fast changes in the energy dynamics, a novel energy-efficient adaptive fuzzy-based CH selection approach is projected. Extensive simulations exploited various real-time scenarios, such as varying the optimal position of the location of the base station and network energy. Additionally, the results showed an improved performance in the throughput (46%) and energy consumption (66%), which demonstrated the robustness and efficacy of the proposed model for the future designs of WSN applications.

ABSTRACT: We propose and demonstrate an in-line Mach-Zehnder interferometer (IMZI) as an optical hydrophone. The IMZI is fabricated by creating two tapers in the single-mode fiber (SMF) and the two tapered sections are separated by a small section of un-tapered SMF. The sensing mechanism is based on the acoustic pressure-induced wavelength shift of the IMZI transmission spectrum. The proposed hydrophone is tested underwater with acoustic signals of different frequencies in the range 15 Hz-250 Hz. For a specific IMZI structure, the hydrophone shows a sensitivity of 27.93 nm/Pa and a noise-limited minimum detectable pressure of 5.53 mPa/√Hz.

ABSTRACT Because of their numerous advantages, offset quadrature amplitude modulation (OQAM) with fifilter bank multicarrier (FBMC) has sparked tremendous interest in recent decades over orthogonal frequency division multiplexing (OFDM). Due to the superimposed formation of OQAM-FBMC signals, however, the largest peak to average power ratio (PAPR) minimization techniques developed for OFDM systems may not be directly applicable to OQAM-FBMC systems. The topic of power ratio reduction technique is discussed technically in this paper, as well as the complementary cumulative distribution function (CCDF) for OQAM-FBMC systems using different companding transforms. Theoretical research and simulation findings demonstrate that the µ-law companding process, as compared to other companding methods, effectively reduces PAPR.

AEU International Journal of Electronics & Communication, Vol. 132, No. 153593.

ABSTRACT: A novel reconfigurable fractal ground loaded monopole antenna with p-i-n diode switching and metamaterial as superstrate for gain and bandwidth enhancement is reported. The proposed structure is a CPW-fed monopole antenna with a Minkowski fractal square ring loaded in the ground plane. The antenna with diode OFF operates at 1.4 GHz, 2.1 GHz, 3.7 GHz, 7.6 GHz and 8.9 GHz. But, with diode switched ON, the resonating frequencies shift to 1.4 GHz, 3.4 GHz, 5.45 GHz, 7.86 GHz and 9.52 GHz respectively. When a metamaterial superstrate is placed on top of the monopole radiator, the respective peak gain of 8.37 dB, 8.67 dB, 5.26 dB, 16.09 dB and 21.58 dB are obtained that justifies the shift of operating bands.

ABSTRACT: A novel metamaterial inspired small array Fabry‐Perot Resonator cavity antenna is designed over a wide‐band dielectric resonator antenna to enhance gain and bandwidth operating at C‐band applications. Further, the cavity resonator is modified with the application of 12 no. of RF p‐i‐n diodes between the upper layer of the posterior unit‐cells to achieve the polarization reconfigurability (PR) keeping the bandwidth, gain and efficiency intact. With the PR architecture, the antenna imparts 4.8 GHz bandwidth operating between 4 and 8.8 GHz with an average simulated efficiency of 72% and an average gain of 20 dBi throughout the operating band. The specific alignment of the diode polarity enables the model to obtain left‐handed circular polarization and/or right‐handed circular polarization.

ABSTRACT: A numerical simulation of a single-junction bi-layer of CIGS based solar cell tandem device is presented. The structure used here is Al:ZnO/CdS/CuIn1-X Ga X Se 2 / CuIn1-y Ga y Se 2  and the software used is WX-AMPS. We proposed to the issue of diffusion (unintentional Ga grading) which occurs at the time of annealing by adding a p-type MoS2 layer in between the bi-layer CIGS to limit the diffusion. The efficiency of the bi-layer device structure with fixed Ga fraction x=(0.31) of the top absorber layer along with Ga fraction y=(0.45) of the bottom absorber layer shows the improved efficiency from 20.56% (Single layer) to 23.6% (bilayer) to  24.17%( bilayer with MoS2).

Abstract: Thin film solar cells based on CZTS based solar cells are very promising, because they contain earth abundant elements.To obtain better performance, we have investigated the output effect of fixed bilayer CZTS/CZTSe structure with band gap 0.9 and 1.5 eV respectively and the effect of MoS2 interfacial layer between CZTS and CZTSe layer to avoid unintentional elemental diffusion. The idea of bilayer CZTS/MoS2/CZTSe structure was exploited to achieve higher open circuit voltage and efficiency by band engineering mechanism. The thin interfacial layer introduced between the two layers ultimately diminishes the recombination process due to the back induced electric field.  The fixed bandgap CZTS/MoS2/CZTSe exhibits better performance.

ABSTRACT: In the present paper, the aim was to dope β gallium oxide with different concentrations of europium. Therefore europium and gallium oxide were co-sputtered to get varying concentrations of europium in β gallium oxide structure. The doping concentration varied from 4.6 to 10.1 mole% of europium. The optical bandgap of β gallium oxide was found to decrease due to doping with europium. Although the transmittance increased drastically with increase in doping concentration from 4.6 to 10.1%, their bandgap was independent of the dopant concentration. In consultation with the binary phase diagram and photoluminescence of the thin films, the optimal dopant concentration in β gallium oxide was found to be around 10% Eu.

Abstract: Considering India’s population growth and paucity of job opportunities, entrepreneurship is the only key to come out of the juncture of unemployment. Entrepreneurship may be in the organised or unorganised form. Unorganised sector in India outweighs the organised sector in this front. But the unorganised sector fails to win the confidence of the stakeholders for its unsystematic approach and unavailability of regulatory framework. This paper unfolds how the unorganised sector in India easily accommodate heavy workforce but with many gray areas. Case study method and in-depth interview method are followed to highlight the problem and focus group discussion is conducted to design a framework for win-win situation.
