Exploring the impact of beauty vloggers’ credible attributes, parasocial interaction, and trust on consumer purchase intention in influencer marketing
Authors: Garg Mukta , Bakshi Apurva 
Published: February 2024

AbstractThe growing usage of digital platforms has made influencer marketing the most cost-effective marketing tool, especially for products consumed by young digital natives. Among other products, these include fashion and beauty-related items such as cosmetics, whose online marketing has created a particular category of influencers called ‘beauty vloggers.’ By applying the source credibility model, this study investigates whether beauty vloggers’ credible attributes (trustworthiness, expertise, and attractiveness) help consumers build trust towards them and whether followers’ trust leads to desirable marketing outcomes (increased purchase intention). Prior literature used the source credibility model in a fragmented manner. However, this study enhances the holistic framework of social media influencers’ impact on purchase intention by investigating all three credible attributes. It specifically addresses the significance of cultivating trust between beauty vloggers and followers, exploring the impact of vloggers’ credible attributes on consumer purchase intention. Additionally, beauty vloggers periodically engage in parasocial interactions to increase closeness with their audiences, affecting consumer behaviour. This study addresses the limited research on the consequences of parasocial interactions in an emerging market context, examining the impact of beauty vloggers’ repeated interactions on consumer behaviour, contributing to a comprehensive understanding of purchase intention using parasocial interaction as an antecedent. The research was conducted on consumers belonging to the age group of 16–45 who use social media platforms daily. Using structural equation modelling via SmartPLS software, the statistical analysis was done on 357 North Indian respondents. The study explores the influence of beauty vloggers on consumers’ purchasing behaviour in the Indian context. The results demonstrate that beauty vloggers’ credibility traits help in influencing consumer behaviour. The findings also revealed that trust partially mediates the impact of credible attributes of beauty vloggers and consumers’ purchase intention. Additionally, the results show that customers’ purchasing decisions might be influenced by repeated parasocial interactions done by beauty vloggers if they perceive them as credible information sources. The findings of the study contribute to help industrial marketers and practitioners of cosmetic companies use influencer marketing strategically in order to increase market sales.
L1 novice writing as a missing piece in the Learner Corpus Research puzzle
Authors: Jadoulle Pauline 
Published: February 2024

Abstract
This paper investigates the possible benefits of integrating an L1 novice corpus into the study of learner
writing, through a study on hedging adverbials and complement clauses. A more traditional tripartite comparison is first drawn
between French EFL learner writing, L1 English novice writing, and English expert writing. Then, a comparison is made between L1
French novice writing and French EFL learner writing. The study uses data from the following corpora: the Varieties of
English for Specific Purposes dAtabase (VESPA; Paquot et al., 2022)
(French EFL learner writing), the British Academic Written English (BAWE; Heuboeck et al., 2008) corpus and the Michigan Corpus of Upper-level Student Papers (MICUSP; Ädel & Römer, 2012) (both L1 English novice writing), the Kulturell Identitet
i Akademisk Prosa: nasjonal versus disiplinavhengig (KIAP‑EN; Fløttum et al.,
2006) corpus (English expert writing), and the The French Academic wRiting (FAR) corpus (L1 French
novice writing). The results speak to the importance of including a L1 novice component to the current methodologies employed in
Learner Corpus Research (LCR), since such inclusion helps to provide a better and more nuanced interpretation of the findings
obtained by means of a more traditional tripartite approach.

A migrant’s public apology as an instance of internalized racism
Authors: Archakis Argiris , Tsakona Villy 
Published: February 2024

Abstract
The aim of this chapter is to investigate how racio-national discourse influences the way migrants perceive
themselves and frame their trajectories in the host community. Within a CDA framework, we analyze an article written by a
young migrant and published in a Greek newspaper of leftwing and antiracist orientation. The article appears to belong to the
genre of public apologies, since the author projects migrants as offenders who harmed the victimized majority. We argue that
such representation of reality indicates migrants’ internalized racism and simultaneously renders the article an instance of
liquid racism, as it is published in a newspaper of antiracist orientation. Through migrants’ reproduction of majority’s
racist accusations against them, the hegemony of Greek racio-national discourse is reinforced.

Authors: Wang Baoku , Yan Fei , Tian Fengjun , Sun Weimin , Li Li 
Published: February 2024

Abstract
Nonlinear metamaterials hold a promising platform for generating terahertz (THz) waves. In this paper, we present an all-dielectric metamaterial with multiple surface plasmon polariton (SPP) resonances for enhanced THz frequency mixing. The metamaterial is composed of graphene ribbons, a dielectric layer, and a one-dimensional photonic crystal, displaying the multiple absorptions with simultaneous excitation of three SPP resonances. Taking advantage of SPP resonances with high Q factor and strong localized field at the input frequency, the third-order nonlinear processes are remarkably enhanced, including third-harmonic generation and four-wave mixing, producing a variety of frequencies in the THz range. The proposed efficient nonlinear metamaterials offer promising applications for THz frequency synthesis.

High harmonic generation in graphene quantum dots
Authors: Zafar Ahmal Jawad , Mitra Aranyo , Apalkov Vadym 
Published: February 2024

Abstract
We study theoretically the generation of high harmonics in disk graphene quantum dots placed in linearly polarized short pulse. The quantum dots (QD) are described within an effective model of the Dirac type and the length gauge was used to describe the interaction of quantum dots with an optical pulse. The generated radiation spectra of graphene quantum dots can be controlled by varying the quantum dot size, i.e. its radius. With increasing the quantum dot radius, the intensities of low harmonics mainly decrease, while the cutoff frequency increases. The sensitivity of the cutoff frequency to the QD size increases with the intensity of the pulse.
Statistics of grain microstructure evolution under anisotropic grain boundary energies and mobilities using threshold-dynamics
Authors: Kim Jaekwang , Admal Nikhil Chandra 
Published: February 2024

Abstract
This paper investigates the statistics of two-dimensional grain microstructures during grain growth under anisotropic grain boundary (GB) energies and mobilities. We employ the threshold dynamics method, which allows for unparalleled computational speed, to simulate the full-field curvature motion of grain boundaries in a large polycrystal ensemble. Two sets of numerical experiments are performed to explore the effect of GB anisotropy on the evolution of microstructure features. In the first experiment, we focus on abnormal grain growth and find that GB anisotropy introduces a statistical preference for certain grain orientations. This leads to changes in the overall grain size distribution from the isotropic case. In the second experiment, we examine the development of texture and the growth of twin boundaries for different initial microstructures. We find that texture development and twin growth are more pronounced when the initial microstructure has a dominant fraction of high-angle grain boundaries. Our results suggest effective GB engineering strategies for improving material properties.
Atomistically informed dislocation dynamics simulations: application to dislocation-loop interactions in zirconium
Authors: Dupuy L M , Kassem W , Clouet E , Onimus F 
Published: February 2024

Abstract
Neutron irradiation of zirconium alloys leads to the formation of high densities of small dislocation loops. Their interactions with gliding dislocations are responsible for hardening and early necking of the material. Multi-scale numerical simulations of the interactions between dislocations and loops are undertaken to predict the mechanical properties evolution of these materials due to irradiation. Molecular dynamics simulations are first performed to assess the critical ingredients needed for dislocation dynamics simulations. Appropriate models and associated coefficients are then introduced in dislocation dynamics simulations in order to reliably reproduce the dislocation line energy, the cross-slip process from basal to prismatic planes and the mobility of straight and jogged dislocations. Based on this parametrization, interactions between dislocations and loops are finally computed with the two numerical methods. Careful comparisons between the two types of simulations show qualitative and quantitative agreement, opening the path to investigations of irradiation effects at the grain scale through large scale dislocation dynamics simulations.

Published: February 2024

Abstract
This study evaluated the efficacy of phytogenic silver and zinc nanoparticles in improving heat resilience in various wheat varieties. The silver and zinc nanoparticles were synthesized using plant leaf extract and characterized using various techniques. Four wheat varieties (DBW187, Black Wheat, DBW 50, and PBW 621) were subjected to field trials. The random block design was used, and nanoparticles in different concentrations were applied at various growth stages and morphologically, and yield parameters were recorded. UV–vis spectroscopy spectral analysis showed peaks for Ag nanoparticles at 420 nm wavelength and Zn nanoparticles at 240 and 350 nm wavelength, depicting the preliminary confirmation of nanoparticle synthesis. Electron microscopic analysis (TEM and SEM) provided morphological insights and confirmed synthesis of fine-sized particle mostly in a range between 10 and 60 nm. Energy dispersive x-ray analysis confirmed the elemental composition of the synthesized nanoparticles, with Ag and Zn elements detected in their respective samples. It also confirmed the oxide nature of synthesized ZnNPs. Dynamic light scattering analysis provided size distribution profiles, indicating average sizes of approximately 61.8 nm for Ag nanoparticles and 46.5 nm for Zn nanoparticles. The concentrations of Ag and Zn nanoparticles in the samples were found to be 196.3 ppm and 115.14 ppm, respectively, through atomic absorption spectroscopic analysis. Fourier transform infrared spectroscopy analysis revealed characteristic functional groups present in the nanoparticles. The results of field experiments established that Ag nanoparticles at 75 ppm concentration exhibited the most significant enhancements in plant growth. Conversely, Zn nanoparticles at a 100 ppm concentration demonstrated the most substantial improvements in the growth and yield of heat-stressed wheat varieties. The study concludes that optimized concentrations of silver and zinc nanoparticles can effectively improve heat stress resilience in wheat. These findings are promising to enhance abiotic stress resilience in crops.

Abstract
Laser-induced periodic surface structure (LIPSS), or nanoripples, is a fascinating laser-induced surface morphology observed on a wide range of solid-state materials, with many potential applications in surface engineering, photonics, and optoelectronic devices. On the specific material of gallium nitride (GaN), the well-known formation mechanism and the potential applications of LIPSS are still being explored. Here, a near-infrared spectra of an ultrashort pulsed laser were used to generate periodic nanostructures with dimensions smaller than the laser wavelength on the surface of a GaN LED. From the result, the LIPSS maintained the direction equivalent to the GaN surface, with periodicity around 140–220 nm perpendicular to <1–100> substrate orientation. Finally, the advances in fabrication of LIPSS are presented as a potential nanograting for increasing the efficiency of LED-based GaN.

Published: February 2024

Abstract
This work demonstrates a single mode fibre-step index multimode fibre-single mode fibre (SMS) structure as saturable absorber (SA) to generate Q-switched laser based on the Kerr-effect of multimode interference (MMI) in an Erbium-doped fibre laser (EDFL) cavity. A 156 mm length of step index multimode fibre (SIMF) was spliced directly into a ring cavity to modulate the cavity loss. By bending and applying proper pressure on the SIMF, steady Q-switched pulse was generated without strict length restriction of the SIMF. The Q-switched laser had a high repetition rate from 87 to 158 kHz, while the corresponding pulse width was low, ranging from 4.2 μs to 2.5 μs as the pump power increased from 115 to 342 mW. The signal-to-noise ratio (SNR) of the fundamental mode for the pulsed laser was about 67 dB at a central wavelength of 1530 nm. The experiment demonstrated that SMS structure can be used as stable SA to generate Q-switched laser for high power applications. It also indicated that even with large core diameter step index multimode fiber, SMS structure can be utilized to generate stable Q-switched pulsed laser with very simple cavity settings.

Abstract
This research presents the first-ever demonstration of a passively Q-switched fiber laser in the 1.5 μm wavelength region using amorphous carbon nitride (a-CNx) as a saturable absorber (SA) in an all-fiber configuration. The a-CNx thin film was prepared using plasma-enhanced chemical vapor deposition. The laser operation showed remarkable stability, achieving a repetition rate of 57.99 kHz and a pulse duration of 1.36 μs at maximum input pump power. The peak power and pulse energy reached 100.56 mW and 136.77 nJ, respectively. The utilization of a-CNx as an SA offers potential benefits such as a simpler and more flexible cavity design, making it an attractive candidate for various applications, including material processing and medical laser equipment. This work contributes to the advancement of fiber lasers and expands the possibilities for utilizing carbon nitride-based SAs in practical laser systems.

Abstract
We have successfully generated soliton mode-locked pulses in a ring Erbium-doped fiber laser (EDFL) cavity using molybdenum disulfide (MoS2) saturable absorber. The MoS2 thin film was grown onto ITO substrate through electro-deposition process using a mixture of 0.5M H2MoO4 and 0.5M Na2S2O3.5H2O as electrolyte solution. The EDFL produced stable soliton pulses operating at centre wavelength of 1557 nm and repetition rate of 1.88 MHz. The mode-locking was realized by injecting pump power within a range from 77 mW to 124 mW. It generates the maximum output power of 0.7 mW and pulse width of 3.0 ps.

Abstract
Perovskite solar cells (PSCs) are cost-effective and efficient photovoltaic cells that show great potential as an alternative to silicon solar cells. They possess desirable properties such as high mobility, direct bandgap, long carrier lifetime, and strong light absorption. However, the traditional materials used for the holes transport layer (HTL) in PSCs, such as PEDOT:PSS, SPIRO-OMETAD, and copper(I) iodide, have durability issues and lower carrier mobility. To overcome these challenges, Zinc Cobaltite (ZnCO2O4) with its advantages of hole transport, wide optical bandgap, and solution processability was investigated as a potential alternative HTL material. Through simulations using OghmaNano software and the Taguchi method, the device structure FTO/TiO2/CsPbI3/ZnCO2O4/Au was analyzed, and the performance was optimized by varying the thickness of the ZnCO2O4 layer. The simulation results showed a power conversion efficiency (PCE) of 32.23% with a ZnCO2O4 thickness of 300nm. ANOVA analysis revealed that the ZnCO2O4 thickness as the HTL had the most significant influence on PCE, followed by environmental temperature and the bandgap of ZnCO2O4. In particular, the ZnCO2O4 thickness had a substantial 70% impact on PCE, indicating that adjusting the thickness of ZnCO2O4 could lead to corresponding improvements in PCE.

Abstract
The third generation of solar cells is dye-sensitized solar cells (DSSC). DSSC can convert solar energy into electrical energy. The main components of DSSC include working electrode, counter electrode, sensitizer, and electrolyte. Substitution of commercial chemicals for the sensitizer (N719) and the counter electrode (platinum) of DSSC will lower the cost of DSSC fabrication. This study focuses on Nitrogen-Doped Carbon Quantum Dots (N-CQDs) synthesized from rice husks as a sensitizer. Then, DSSC with sensitizer of N719 (Pt-1) and N-CQDs (Pt-2) were compared. Furthermore, the N-CQDs residue in solid carbon was used as the counter electrode material using different sensitizers N719 (C-1) and N-CQDs (C-2). Based on the results, the FTIR characterization of N-CQDs showed the functional groups N-H, O-H, C=O, and CN. The UV-VIS characterization of N-CQDs had absorbance in the wavelength range of 200-400 nm. Pt-2 has an efficiency value of 0.258%, Jsc of 2.188 mA/cm2 Voc of 0.6 volts, and FF of 0.20. C-2 has an efficiency of 0.0010%, Jsc of 0.042 mA/cm2 Voc of 0.131 volts, and FF of 0.17. This confirms that N-CQDs can be used as a sensitizer and counter electrode material, although the results are not as good as commercial chemicals.

Published: February 2024

Abstract
Fast prediction of high-directivity antenna characterization has been presented. The Cassegrain antenna working at J band frequency has been evaluated using a terahertz (THz) photonic system based on near-field measurement. The generation and detection of THz signal are based on a non-polarimetric electrooptic (EO) frequency down-conversion technique combined with a self-heterodyne system. The synthesis method is introduced to estimate far-field E and H-plane antenna characteristics. The antenna result is calculated using amplitude and phase-synthesized data based on the measured data. A near-field (NF) to far-field (FF) transformation is employed in the antenna radiation pattern. The effect of blocking objects on the antenna (supporting rods and sub-reflector) is discussed. The antenna characteristics of the measured and synthesized data are compared to the ITU F.699 recommendation. The synthesized result agrees with the measured one on the main lobe angle.
