Authors: Mehta Vibha , Rahul J. S. , Shukla Harsh Vardhan , Pandey Khushboo 
Published: March 2023

AbstractJust as the country has recently dealt with the increase in COVID-19 and monkey pox cases, another dark cloud of “Tomato flu/ Tomato fever” loomed the skies of the nation. As of 24 august, 2022, 100 kids mainly below the age of 5 have been reported showing symptoms of the flu. Another state of Odisha, suspected similar infectious etiology in 36 cases out of which 26 Children were below the age of 10. This endemic viral illness has triggered an alert to the neighboring states of Tamil Nadu and Karnataka, along with the entire nation at large. The wrath of this disease is not just restricted to India but crossing borders. Tang, et al reported a case of a 13-month-old female child and her 5-year old brother based in United kingdom with similar etiology. Through this report, we aim to alert the frontline pediatricians, who are most likely to come across and manage such daunting cases with these non-specific clinical features in their routine clinical practice across the globe. Early and extreme preventive and surveillance measures must be undertaken to prevent substantial loss in public and private sector

Recent investigations have suggested that the use of non-classical states of light, such as entangled photon pairs, may open new and exciting avenues in experimental two-photon absorption spectroscopy. Despite several experimental studies of entangled two-photon absorption (eTPA), there is still a heated debate on whether eTPA has truly been observed. This interesting debate has arisen mainly because it has recently been argued that single-photon-loss mechanisms, such as scattering or hot-band absorption, may mimic the expected entangled-photon linear absorption behavior. In this work, we focus on transmission measurements of eTPA and explore three different two-photon quantum interferometers in the context of assessing eTPA. We demonstrate that the so-called N00N-state configuration is the only one among those considered insensitive to linear (single-photon) losses. Remarkably, our results show that N00N states may become a potentially powerful tool for quantum spectroscopy, placing them as a strong candidate for the certification of eTPA in an arbitrary sample.
Cicero’s De Officiis, politeness and modern conduct manuals
Authors: Hall Jon 
Published: March 2023

Abstract
This paper considers the guidelines for polite conversation and appropriate comportment presented in Cicero’s
philosophical treatise De Officiis (44 bce), examining them in the light of recent scholarship on modern
conduct manuals (e.g., Terkourafi [2011], Alfonzetti [2016], Culpeper [2017] and Paternoster and Saltamacchia [2017]). In particular, it considers: (1) Cicero’s attempt to impose order on
conversational practices; (2) his guidelines on rebuking others appropriately (a topic often omitted from modern manuals); (3) the
ways in which his views on conversation coincide with modern theories of politeness; (4) his association of polite manners with
moral behaviour and social class; and (5) the role of caricature in his depictions of inappropriate behaviour.
A culture of “pleasing”?
Authors: Held Gudrun 
Published: March 2023

Abstract
This paper seeks to explain the development of European politeness as a result of courtly behaviour where
“complaisance” played an important role. As traces left in the so-called “language of politeness” of numerous European
linguacultures show, mutual “pleasing” determined social performance in hierarchically organised societies by merging aesthetic
concepts of form and order with ethical values of benevolence and charity. An analysis of the lexical item
placere (‘to please’) in Early Modern Italian and French documents highlights the existence of six different
formulaic usages, characterised by a high consistency in frequency, evolution and diffusion all over Europe. Appearing mainly in
connection with interactive moves where will is at stake, placere-formulae represent co-operative means, which
ease social relationships by conditioning and “embellishing” directives with different elements of social
decorum. As acts of submission originating in the Medieval ars dictandi, they became integrated
over time into the French dogma of “polished” conversation as an elitist “art de plaire” (Faret 1665). From France they spread into the European courts establishing a conception of politeness that has been
underestimated in pragmatics so far.
The neural correlates of second language syntax
Authors: Veisi Soheila , Samar Reza Ghaffar 
Published: March 2023

Abstract
An important dimension that characterizes the contextual differences in second language acquisition (SLA) is the
degree to which instruction is implicit or explicit. However, whether these differences in
context play a role in determining the neural activity to process L2 grammar has not been well characterized. The present study
investigated this issue by comparing the neural regions activated in response to novel L2 syntactic rules acquired under
conditions of implicit and explicit instruction. In addition, participants’ declarative and procedural memories were measured to
better understand the mediating effect of memory during learning under different conditions. Explicitly and implicitly instructed
learners showed statistically indistinguishable behavioral performance. Region of interest (ROI) analysis also revealed that the
task activated both declarative and procedural memory structures suggesting that instructional context did not affect the
recruitment of memory systems when processing L2 syntax.
Variations of polyphony in blogs
Authors: Bondi Marina , Nocella Jessica Jane 
Published: March 2023

AbstractThis paper looks at dialogicity in the Slow Art Day blog and focuses on the way the representation of participants encodes the complexity of the communicative action through a polyphony of textual voices. By focusing on posts from the pandemic years (2020 and 2021), and contrasting them with the previous period, we carry out a collocation analysis and a study of semantic preferences (Sinclair 2004) to explore how writers present themselves and how they interact with the reader and other textual voices in a context of cultural intermediation. By looking at forms of address and of self-mention, we trace how this blog enacts different forms of dialogic action with its readers and stakeholders in the extended situational context.
The affordances of an intercultural e-portfolio
Authors: Hanukaev Anastasia 
Published: March 2023

Abstract
This paper explores teachers’ perceptions of the affordances of an e-portfolio of intercultural competence (EPIC). The EPIC was implemented during an 8-week intervention carried out in a Norwegian lower secondary school. Data were collected from various sources (e.g., learners’ texts, focus group interviews), but this paper draws on the data from three individual teacher interviews conducted in the spring semester 2018. This study extends our understanding of the way an e-portfolio can be integrated into the English as a foreign language (EFL) classroom as a tool for promoting intercultural competence. The findings underscore the affordances of the e-portfolio to track the learners’ reflections on their own complex selves and others; moreover, the use of the e-portfolio enabled the teachers to create flexible and varied learning spaces, which in turn provided opportunities for intercultural language learning. Pedagogical implications are provided on how foreign language (FL) teachers might support intercultural competence development through the use of the e-portfolio.
El análisis pragmalingüístico al servicio de la traducción
Authors: Ramos Sañudo Ana María 
Published: March 2023

Resumen
El objetivo de nuestro trabajo es demostrar que el análisis pragmalingüístico debe constituir una herramienta más para el traductor. De hecho, puede resultar indispensable a la hora de buscar la mejor equivalencia de marcadores discursivos fraseológicos como il n’y a pas à dire, cuya traducción del francés al español supone una gran complejidad por diferentes razones: la imposibilidad de efectuar una traducción literal de la secuencia, la coexistencia de una secuencia que funciona libremente junto a la secuencia fijada como marcador epistémico, y las limitaciones que presentan los recursos lexicográficos y traductológicos consultados. Para hacer frente a estas dificultades, proponemos apoyarnos en las conclusiones del análisis pragmalingüístico de la unidad en la lengua de origen, lo que pondrá de manifiesto las particularidades de su funcionamiento discursivo y permitirá establecer una serie de equivalencias válidas para su traducción al español.

The gravito-electromagnetic approximation to the gravimagnetic dipole and its velocity rotation curve
Authors: Govaerts Jan 
Published: March 2023

AbstractIn view of the observed flat rotation curves of spiral galaxies and motivated by the simple fact that within Newtonian gravity a stationary axisymmetric mass distribution or dark matter vortex of finite extent readily displays a somewhat flattened out velocity rotation curve up to distances comparable to the extent of such a vortex transverse to the galaxy’s disk, the possibility that such a flattening out of rotation curves may rather be a manifestation of some stationary axisymmetric space-time curvature of purely gravitational character, without the need of some dark matter particles, is considered in the case of the gravimagnetic dipole carrying opposite Newman–Unti–Tamburino charges and in the tensionless limit of its Misner string, as an exact vacuum solution to Einstein’s equations. Aiming for a first assessment of the potential of such a suggestion easier than a full-fledged study of its geodesics, the situation is analysed within the limits of weak field gravito-electromagnetism and nonrelativistic dynamics. Thereby leading indeed to interesting and encouraging results.
Gravitational duality, Palatini variation and boundary terms: a synopsis
Authors: Lindström Ulf , Sarıoğlu Özgür 
Published: March 2023

Abstract
We consider f(R) gravity and Born–Infeld–Einstein (BIE) gravity in formulations where the metric and connection are treated independently and integrate out the metric to find the corresponding models solely in terms of the connection, the archetypical treatment being that of Eddington–Schrödinger (ES) duality between cosmological Einstein and Eddington theories. For dimensions

, we find that this requires f(R) to have a specific form which makes the model Weyl invariant, and that its Eddington reduction is then equivalent to that of BIE with certain parameters. For D = 2 dimensions, where ES duality is not applicable, we find that both models are Weyl invariant and equivalent to a first order formulation of the bosonic string. We also discuss the form of the boundary terms needed for the variational principle to be well defined on manifolds with non-null boundaries. This requires a modification of the Gibbons–Hawking–York (GHY) boundary term for gravity. This modification also means that the dualities between metric and connection formulations are consistent and include the boundary terms.

AbstractWe present the second data release of gravitational waveforms from binary neutron star (BNS) merger simulations performed by the Computational Relativity (CoRe) collaboration. The current database consists of 254 different BNS configurations and a total of 590 individual numerical-relativity simulations using various grid resolutions. The released waveform data contain the strain and the Weyl curvature multipoles up toℓ=m=4. They span a significant portion of the mass, mass-ratio, spin and eccentricity parameter space and include targeted configurations to the events GW170817 and GW190425.CoResimulations are performed with 18 different equations of state, seven of which are finite temperature models, and three of which account for non-hadronic degrees of freedom. About half of the released data are computed with high-order hydrodynamics schemes for tens of orbits to merger; the other half is computed with advanced microphysics. We showcase a standard waveform error analysis and discuss the accuracy of the database in terms of faithfulness. We present ready-to-use fitting formulas for equation of state-insensitive relations at merger (e.g. merger frequency), luminosity peak, and post-merger spectrum.

Abstract
Flexible electronic devices have received increasing attention due to their potential applications in wearable human motion and healthcare monitoring and thermal management. Nevertheless, flexible electronic devices for more precise health monitoring of human physiological movement under low strain are still a pressing issue to solve. Herein, a wearable flexible strain sensor with a three-dimensional (3D) conductive network is developed for healthcare monitoring and thermal management by embedding silver nanowires (AgNWs) and Ti3C2T
x
MXene composite films into a polydimethylsiloxane matrix. The sensor can be utilized for human health monitoring, pulse detection at the wrist, and breathing monitoring of human physiological movement due to its low strain detection capacity (0.05% strain) and high sensitivity (gauge factor up to 9472). The primary detection range of the sensor is 0%–1% of tiny strains. Moreover, the exceptional electric heating and optothermal effect supported by the AgNWs and MXene protects human health in extremely cold environments. The MXene/AgNW strain sensor with high sensitivity under low strain has great potential for more precise health monitoring of human physiological movements and thermal management.
Intelligent electromagnetic mapping via physics driven and neural networks on frequency selective surfaces
Authors: Miao Wuxia , Zhang Lamei , Zou Bin , Ding Ye 
Published: March 2023

Abstract
The high mapping efficiency between various structures and electromagnetic (EM) properties of frequency selective surfaces (FSSs) is the state-of-the-art in the EM community. The most straightforward approaches for beam analysis depend on measurements and conventional EM calculation methods, which are inefficient and time-consuming. Equivalent circuit models (ECMs) with excellent intuitiveness and simplicity have been put forward extensively. Despite several applications, bottlenecks in ECM still exist, i.e. the application scope is restricted to narrow bands and specific structures, which is triggered by the ignorance of EM nonlinear coupling. In this study, for the first time, a lightweight physical model based on neural network (ECM-NN) is proposed , which exhibits great physical interpretability and spatial generalization abilities. The nonlinear mapping relationship between structure and beam behavior is interpreted by corresponding simulations. Specifically, two deep parametric factors obtained by multi-layer perceptron networks are introduced to serve as the core of lightweight strategies and compensate for the absence of nonlinearity. Experimental results of single square loop (SL) and double SL indicate that compared with related works, better agreements of the frequency responses and resonant frequencies are achieved with ECM-NN in broadband (0–30 GHz) as well as oblique incident angles (0°–60°). The average accuracy of the mapping is higher than 98.6%. The findings of this study provide a novel strategy for further studies of complex FSSs.
Frequency-selective valley edge routing of elastic wave in topological phononic crystals with different symmetries

Published: March 2023

Abstract
The control of propagation direction or path of edge states is difficult when the chirality of the excitation source and the boundary structures are determined. Here, we studied a frequency-selective routing for elastic wave based on two types of topological phononic crystals (PnCs) with different symmetries. By constructing multiple types of interfaces between different PnCs structures with distinct valley topological phases, the valley edge states of elastic wave could be realized at different frequencies in the band gap. Meanwhile, based on the simulation of topological transport, it is found that the routing path of elastic waves valley edge states highly depends on the operating frequency and the inputting port of the excitation source. By varying the excitation frequency, the transport path can be switched. The results provide a paradigm for the control of elastic wave propagation paths that could be employed for designing the frequency-dependent ultrasonic division devices.

Authors: Liao Yanguo , Xie Shuibo 
Published: March 2023

Abstract
Based on the cylindrical indentation experiments, a novel model for characterizing the elastic mechanical property of transversely isotropic materials has been established. The cylindrical indentation of transversely isotropic materials was theoretically and dimensionally analyzed. Three-dimensional (3D) indentation experiments that encompass the wide range of transversely isotropic material parameters were simulated by finite element. The effect of each parameter (transversely isotropic Young’s modulus, EP
, longitudinal Young’s modulus, EL
, longitudinal shear modulus, GL
, and loading orientation angle, α) on the normalized indentation modulus was investigated. Then, the dimensionless analytical relationship between indentation moduli and elastic parameters was obtained at three different indentation orientations

. Several groups of transversely isotropic materials were selected as input parameters to carry out numerical indentation experiments for the error analysis. The sensitivity of the calculated elastic parameters to the experimental data was analyzed. Simultaneously, the technique was used in the particular case of a Zinc single-crystal material, and the accuracy of these derived formulas was verified. The good agreement shows that the proposed method is reliable and could be applied to characterize the elastic parameters of transversely isotropic materials.

Net radially inward turbulent particle flux was observed in a linear plasma device, the linear experimental advanced device (LEAD). The amplitude of the inward particle flux is comparable with outward particle flux. The inward particle flux peak value locates in the outer E

shear layer. Cross-phase evolution dominates the radial evolution of particle flux from outward to inward. In the frequency domain, a 1 kHz mode contributes most of the inward particle flux. Frequency-resolved energy transfer analysis infers that this mode obtains energy nonlinearly from very low frequency fluctuations below 0.5 kHz. Moreover, turbulence spreading could also transfer energy to the position where the inward flux peak locates from nearby positions, and thus acts as a nonlocal, nonlinear drive for the 1 kHz mode.

at 1–2 GHz and 1.5 K and the breakdown radio-frequency (rf) fields H close to the dc superheating field of the Meissner state. These advances raise the questions of whether the state-of-the-art cavities are close to the fundamental limits, what these limits actually are, and to what extent the Q and H limits can be pushed by the materials nano structuring and impurity management. These issues are also relevant for many applications using high-Q thin film resonators, including single-photon detectors and quantum circuits. This topical review outlines basic physical mechanisms of the rf nonlinear surface impedance controlled by quasiparticles, dielectric losses and trapped vortices, as well as the dynamic field limit of the Meissner state. Sections cover methods of engineering an optimum quasiparticle density of states and superfluid density to reduce rf losses and kinetic inductance by pairbreaking mechanisms related to magnetic impurities, rf currents, and proximity-coupled metallic layers at the surface. A section focuses on mechanisms of residual surface resistance, which dominates rf losses at ultra low temperatures. Microwave losses of trapped vortices and their reduction by optimizing the concentration of impurities and pinning potential are also discussed.
