Introduction
Authors: Rüdiger Sofia , Mühleisen Susanne 
Published: February 2022

Abstract
This editorial introduction establishes the theoretical basis for the special issue Formality and Informality in Online Performances with a focus on (in)formality, Goffman’s (1959) notion of front– and backstage and the internet as a stage, as well as the performance of self. Further attention is given to notions of self-branding, micro-celebrity, and self-disclosure. Explicit discussion of the linguistic construction of formality and informality in performative online settings has been rare and the articles in this issue aim at investigating the complex interplay between context, (in)formality, and performance on different digital platforms (ranging from rather traditional web forums to YouTube, Reddit, Instagram, and WeChat Moments). The contributions thus shed light on some of the intricate performative processes which are at the heart of online communication and offer manifold perspectives on (in)formality online.
Non-commutativity and non-inertial effects on a scalar field in a cosmic string space-time: I. Klein–Gordon oscillator
Authors: Cuzinatto Rodrigo Rocha , de Montigny Marc , Pompeia Pedro José 
Published: February 2022

Abstract
We analyse the Klein–Gordon oscillator in a cosmic string space-time and study the effects stemming from the rotating frame and non-commutativity in momentum space. We show that the latter mimics a constant magnetic field, imparting physical interpretation to the setup. The field equation for the scalar field is solved via separations of variables, and we obtain quantization of energy and angular momentum. The space-time metric is non-degenerate as long as the particle is confined within a hard-wall, whose position depends on the rotation frame velocity and the string mass parameter. We investigate the energy quantization both for a finite hard-wall (numerical evaluation) and in the limit of an infinite hard-wall (analytical treatment). We stress the effect of non-commutativity upon the energy quantization in each case.

Published: February 2022

Abstract
Last decade has seen an explosion in the exploration of two-dimensional materials for optoelectronic applications owing to their novel optical and electronic properties. However, these materials, in general, are poor light absorbers with restricted spectral responsivity which limits their efficiency. Integration of these two-dimensional materials with each other and with plasmonic metal nanostructures enhances their light absorption efficiency and also influence the electronic properties. This review highlights the optical and electronic properties of two-dimensional materials integrated with other plasmonic two- dimensional materials or with plasmonic metal nanostructures. In addition, an overview of the optoelectronic properties of plasmonic nanostructure integrated two-dimensional heterostructures is also presented.
Phase transition of supercooled water confined in cooperative two-state domain
Authors: Li Peizhao , Lu Haibao , Fu Yong-Qing 
Published: February 2022

Abstract
The question of ‘what is the structure of water?’ has been regarded as one of the major scientific conundrums in condensed-matter physics due to the complex phase behavior and condensed structure of supercooled water. Great effort has been made so far using both theoretical analysis based on various mathematical models and computer simulations such as molecular dynamics and first-principle. However, these theoretical and simulation studies often do not have strong evidences of condensed-matter physics to support. In this study, a cooperative domain model is formulated to describe the dynamic phase transition of supercooled water between supercooled water and amorphous ice, both of which are composed of low- and high-density liquid water. Free volume theory is initially employed to identify the working principle of dynamic phase transition and its connection to glass transition in the supercooled water. Then a cooperative two-state model is developed to characterize the dynamic anomalies of supercooled water, including density, viscosity and self-diffusion coefficient. Finally, the proposed model is verified using the experimental results reported in literature.

Published: February 2022

Abstract
In this paper we will show that photon–photon collision experiments using extreme lasers can provide measurable effects giving fundamental information about the essence of QED, its Lagrangian. A possible scenario with two counterpropagating ultra-intense lasers for an experiment to detect scattering between optical photons is analyzed. We discuss the importance of the pulse widths and waists, the best scenario for overlapping the beams and signal detection, as well as ways to distinguish the signal from the noise. This would need a high-precision measurement, with control of temporal jitter and noise. We conclude that such experiment is barely feasible at 1023 W cm−2 and very promising at 1024 W cm−2.
Quantum synchronisation and clustering in chiral networks
Authors: Lorenzo Salvatore , Militello Benedetto , Napoli Anna , Zambrini Roberta , Palma G Massimo 
Published: February 2022

Abstract
We study the emergence of synchronisation in a chiral network of harmonic oscillators. The network consists of a set of locally incoherently pumped harmonic oscillators coupled pairwise in cascade with travelling field modes. Such cascaded coupling leads to feedback-less dissipative interaction between the harmonic oscillators of the pair which can be described in terms of an effective pairwise Hamiltonian a collective pairwise decay. The network is described mathematically in terms of a directed graph. By analysing geometries of increasing complexity we show how the onset of synchronisation depends strongly on the network topology, with the emergence of synchronised communities in the case of complex networks. The quantum nature of the non local correlation between network nodes is assessed.
A study on the electronic properties of A site and B site doped SrTiO3 for thermoelectric applications using first-principles calculations
Authors: Arava Clement Manohar , Nayak Sanjib , Chan Kwok Sum , Roy Vellaisamy A L 
Published: February 2022

Abstract
In SrTiO3, the nature of dopants and their substitution at the A or B site becomes a critical factor in determining the electrical conductivity, Seebeck coefficient, and thermal conductivity. The electronic band structure and the density of states (DOS) for the ab-initio study using different dopants were estimated using PBE-GGA approximation. The size, site of substitution, and nature of dopants cause significant changes in the lattice dimensions, band structure, band curvatures, and the density of states, which reflect as changes in the effective mass

is calculated from the curvature of the bottom-most conduction band using the one-band effective mass approximation. Pentavalent substitutions on the B site of SrTiO3 affect the conduction band’s curvature differently than with trivalent substitutions on the A site. They also exhibit an opposite trend in the change in band curvature according to the dopant’s ionic radius. In contrast, isovalent dopants showed no change in the band curvature except for the bandgap modification. In this paper, we have provided a semi-quantitative understanding regarding the thermoelectric properties like conductivity and Seebeck coefficient that get affected due to the substituent’s nature and site at which it substitutes.
On the dynamics of a Caputo-like discrete fractional Rössler system: chaos, stabilization and synchronization
Authors: Azil Souaad , Odibat Zaid , Shawagfeh Nabil 
Published: February 2022

Abstract
This study examines the dynamics of a novel Caputo-like discrete fractional Rössler system. The dynamics of this discrete fractional system are numerically analyzed using phase portraits, bifurcation diagrams and Lyapunov exponents. The study confirmed the existence of chaos in the proposed system where one scroll chaotic attractors are displayed. Control laws are presented to force the states of the proposed system to converge asymptotically to zero and to exhibit complete synchronization of coupled Caputo-like discrete fractional Rössler systems. Numerical simulations are introduced to illustrate the findings of this study.
A new analysis of galaxy 2-point functions in the BOSS survey, including full-shape information and post-reconstruction BAO
Authors: Chen Shi-Fan , Vlah Zvonimir , White Martin 
Published: February 2022

Abstract
We present a new method for consistent, joint analysis of the pre- and post-reconstruction galaxy two-point functions of the BOSS survey. The post-reconstruction correlation function is used to accurately measure the distance-redshift relation and expansion history, while the pre-reconstruction power spectrum multipoles constrain the broad-band shape and the rate-of-growth of large-scale structure. Our technique uses Lagrangian perturbation theory to self-consistently work at the level of two-point functions, i.e. directly with the measured data, without approximating the constraints with summary statistics normalized by the drag scale. Combining galaxies across the full redshift range and both hemispheres we constrain Ωm = 0.303 ± 0.0082, H
0 = 69.23 ± 0.77 and σ8 = 0.733 ± 0.047 within the context of ΛCDM. These constraints are consistent both with the Planck primary CMB anisotropy data and recent cosmic shear surveys.
An Overview of Advanced Oxidation Process and Outlook
Authors: Sun Xiangbo 
Published: February 2022

Abstract
With the development of industry and agriculture, water contamination comes more and more serious even threatens human health. Advanced oxidation processes are widely used in waste water treatment because of their high efficiency, among them peroxymonosulfate (PMS) activate by catalysts to release sulfate radicals and hydroxyl radicals is the best way of removing recalcitrant organic pollutants in water. Cobalt ion and cobalt oxides can activate PMS efficiently, however their high toxicity will contaminate the environment terribly and even cause human cancer, which restrains the extensive utilization. Compared with cobalt, manganese is more environment-friendly with low toxicity and abundant content, meanwhile manganese oxides are given excessive focus due to its high catalytic efficiency, which makes it can be used in practical situations.
Machinability of Non-Conductive Ceramic by EDM: A Review
Authors: Baghel Rupali 
Published: February 2022

Abstract
AdvancedCeramics are gaining a foothold in the lightweight aerospace, electronics, and structural engineering component markets. These ceramics could be extensively used in modern industry, such as ballistic body armour, ceramic carbon fibre composite automoti ve brakes, diesel particulate filters, prosthetic limbs, piezoelectric sensors, and computer memory products, due to their higher compressive strength, resistance to abrasion, lower thermal expansion coefficient, higher density, and chemical stability. Ceramics are notori ously difficult to handle due to the increased hardness and brittleness. Low electric-conductive ceramics, on the other hand, can be machined using the EDM technique, in which plasma energy is used to accurately remove the material by continuous sparking between the surface and the electrode submerged in dielectric. It is observed that EDM can be applied to the material having electrical resistivity below 100 ?.cm. Most recently it has been observed that EDM could be applied to insulating ceramics too. An attempt has been made in this paper to critically review the machining of ceramics by the EDM process.
Study and Design of Arduino Based CNC Laser Cutting Machine
Authors: Nasir Khan Mohammad , Maheshwari Ambuj , Verma Himanshu 
Published: February 2022

Abstract
For precise job manufacturing, system should possess good dimensional accuracy and surface finish. In applications like drilling, punching, marking, boring, tapping work piece is positioned firstly and then cutting tool performs its action while motion axes are kept stationary. In traditional approach for such applications, manufacturer uses highly expensive CNC machine for programming job cycle and executing the same. Big scale manufacturer can afford such highly expensive machines but for small scale mechanical job manufacturing industry we have to think of low-cost solution that can deliver high class output. In this project we are trying to propose low-cost design which gives similar functionality as that of high-cost CNC machine. By applying this machine in industry, it can acquire the multi generation brief time. In order to perform some operation which requires continuous cutting over a pre-defined curve, CNC machines are used as the traditional machines in the industry. Installation of a CNC machine requires a high financial investment and a skilled labour to perform the different operations on the machine. Apart from that the maintenance cost of such machine are also high. In small scale industries where the operations are performed on small job pieces, the installation of such high-cost CNC machine is very difficult; hence this project work is taken up in which a low-cost CNC laser cutting machine is designed using the Arduino. This CNC laser cutting machine will be quite useful for small scale industries where the job size is not very large. Also, the machine does not require a highly skilled labour to perform operations.

Published: February 2022

Abstract
The purpose of this study is to understand the influence of processing parameters on surface roughness and material removal rate of EN31 Alloy Steel. Three input parameters are considered in this study, namely, the speed of the grinding wheel, number of passes and the depth of cut. The L16 orthogonal array design is used to analyse these process parameters. The results show that cutting depth and grinding wheel speed are the most effective parameters affecting material removal rate and cutting depth, and the number of passes is the most effective parameter affecting surface roughness. In addition, result showed that, the maximum MRR is 0.79051 g/sec and the surface roughness is 0.14000 µm. Therefore, it can be concluded that compared with other materials, cutting depth and wheel speed are less effective parameters, but compared with EN31 alloy steel, cutting depth and grinding wheel speed are the most effective parameters.

Authors: Alam Zafar , Hussain Taliv 
Published: February 2022

Abstract
The foremost idea of this current effort is to study the performance parameters of silica gel based desiccant dehumidifier and optimize its performance on the basis of Process air inlet velocities and air inlet temperatures. Desiccant dehumidifier considered in this work is coupled with the VCRS system. This Analysis is carried out for hot and humid conditions at four different air velocities (i.e. 2.8, 3.5, 4.5, 5.2 m/s) and different ambient temperatures (i.e. 32, 33, 34, 35°C). Regeneration rate and adsorption rate at different air flow rates and at different ambient temperatures is analysed. Regeneration is occurring through an electric heater fitted in the regeneration sector. Thermal factors, for instance temperature (dry bulb) and relative dampness are measured to enhance performance parameters like Adsorption rate, latent COP, Regeneration rate and Effectiveness of desiccant of wheel. Revamp values of this parameters are obtained at 3.5 m/s entering velocity of process air and 34°C ambient temperature which results in better performance of desiccant dehumidifier with less energy utilization for the conditioned space.

Authors: Gawade Shubham , Shewale Sandeep P. , Gode Amravati 
Published: February 2022

Abstract
The aqueous two-phase separation system (ATPS) signifies an environmentally responsible approach for the extraction of bioactive compounds from a plants basis, as it is a liquid-liquid fractionation technique centred on the inconsistency of two aqueous solutions. In this investigation, various experimental parameters are optimized as the speed of agitation (200, 300 400 and 500 rpm) and solvent ratio (1:1, 2:3 and 3:2) with 20 % (w/w) of Ammonium Sulphate (AMS) salt composition and 30 % (w/w) of Polyethelyene Glycol (PEG). The obtained extract contains alkaloids, flavonoids, tannins, glycosides, acids and total phenolic compounds (TPC). The extracted Oleic acid by the ATPS method was measured with gallic acid equivalent (GAE) of TPC extracted from neem leaves powder. The determined concentration of oleic acid in the practice of TPC is 8.033 mg of GAE/g from the optimized experimental parameter. The optimized results can be cast off for a commercial process on an industrialized scale. Also, the mathematical modelling investigation was done to intent the critical impeller speed (Njs) with the Zwittering model. The identified model calculates the essential speed of agitation (rpm) for maximum extraction yield.

Fabrication and Estimation of Rice Husk Green Composite
Authors: Nasir Khan Mohammad , Ahmad Ansari Usman 
Published: February 2022

Abstract
Composite materials form an important part of technical materials, from everyday products such as door frames to aircraft and space applications. The availability of natural fibres and the ease of production have prompted researchers to test inexpensive local fibres and examine their feasibility for reinforcement purposes and the extent to which these meet the specifications required for strong reinforced polymer composites. A lot of rice husk (RH) is believed to contain high silica fibre content. Depending on the size, the silica content and all impurities in the RH will vary. RHs mainly contain 15-20 wt. percent silica and various organic components are produced by thermal degradation. The low density and diversity of raw materials make silicon carbide easy to produce. In the current work, two different materials are considered for the production of composite materials, such as rice husk and polypropylene. These two available materials are considered as different components, and for each component, various parameters are evaluated to detect the usability of composite materials. In the research work, the proposed composite GUI production method was created using MATLAB, and different results were evaluated for different variables. According to the results, the RH mixture in PP has caused some changes in the various properties of the material, such as tensile strength, tensile modulus, fixture strength, porosity, and for different components, varied outcomes were obtained. According to application requirements, the composition of the material can be further considered. If good tensile strength is required, the minimum RH in the composition is considered. If a higher tensile modulus is required, the high RH composition of PP can be used for further consideration.

Authors: Zhang Jinrun , Fan Fan , Fu Wenxin , Zeng Jinwei , Wang Jian 
Published: February 2022

Abstract
Polarization is a fundamental physical dimension of electromagnetic waves. However, experimental determination of polarization states of light is inherently challenging and inconvenient due to the loss of phase information in conventional optical characterization. In particular, the Stokes parameters are a critical indicator to fully describe arbitrary polarization state, which, however, require multiple intensity measurements in three orthogonal polarization bases. Here, we design and experimentally demonstrate a multi-tasking geometric phase element array to unveil all Stokes parameters in one shot. Such a method is convenient, broad-band, real-time with compact size to accurately characterize the complex polarization states of coherent light, which may find visionary applications in structured light microscopy, polarizable quantum computation, and communication, etc.

Published: February 2022

Abstract
In this work, we present an introduction to the field of spatially partial coherent beams, while keeping in mind the transverse structure of an optical field. We look closely at the concept of spatial coherence and show some strategies to deal with it. We work step–by–step with the reader and construct as an example, a partially coherent vortex beam. Finally, using numerical simulations, the richness in structure of a partially coherent field is revealed through its cross–correlation function.
