Identification and Intervention of Hearing Loss in Maharashtra: A Survey of Parental Experience
Authors: Deshpande Shweta , Bhogade Madhuri Ramdas 
Published: May 2023

Abstract
Background Universal newborn hearing screening is not yet fully implemented in India at a national level due to many challenges like cost, limited specialist staff, loss to follow-up, and importance of hearing in speech language development. Most often the parents identify and initiate intervention for the child's hearing loss after the critical period of development is over. There is a need to explore the age at which children are detected and identified with hearing loss, fitted with appropriate intervention, and the barriers faced during this process.
Method Data was collected from parents of 60 children with hearing loss aged between 2 and 6 years. A questionnaire comprising of 27 items was developed and administered on parents through face-to-face and telephonic interviews. The data was descriptively analyzed to study the parents’ responses.
Results The median age at suspicion was 12 months, median age at identification was 18 months, and age at initiation of intervention was 24 months in children with hearing loss between the age range of 2 to 6 years. Financial constraint was reported to be the most common barrier among the others faced by the parents.
Conclusion This study highlights the current status of the age at identification and intervention of hearing loss in children in Maharashtra. These findings can help to create awareness regarding the need for early identification and appropriate management in children with hearing loss for development of adequate verbal communication skills.
Body-worn camera activation in prisons: understanding correctional officers’ decision-making and use of discretion
Authors: Dodd Shannon , Antrobus Emma , Sydes Michelle 
Published: May 2023

AbstractCorrective service agencies worldwide have started to introduce body-worn cameras (BWCs) in prisons as part of correctional officers’ personal protective equipment. Like the policing context, this technology is often introduced in haste, with little consideration of the privacy and ethical concerns that may be raised through this more intensive form of prisoner surveillance. No studies to date have explored the decision-making of correctional officers around BWCs. Thus, this article details a mixed-methods study of correctional officers’ use of BWCs in Queensland, Australia. This study demonstrates how correctional officers exercise their discretion around BWC use, including how and in what situations they activate their camera and the ways they navigate the use of this technology amidst prisoner privacy and security concerns.
An investigation of pathways for rebuilding Australia’s sheep flock
Authors: Brien F. D. , Pitchford R. L. , Vogt S. P. , Koopman D. J. 
Published: May 2023

Context A significant opportunity remains to further increase the supply of premium sheepmeat products to Australia’s customers, which requires a more rapid rebuilding of the national sheep flock. To help meet this challenge, developing relevant information for sheep producers to assist them to achieve a profitable flock-rebuilding outcome is viewed as highly desirable. Aims (1) Develop flock-rebuild scenarios that track inventory, cashflow, profit and loss, and the overall balance sheet over a 5-year projection. (2) Model the impact on flock-rebuilding pathways of exposure to variation in supplementary-feed costs, purchase of stock and price received for sale animals and flock structure. (3) Model variation in benefits and costs for a range of production zones, enterprise types and flock-age profiles. Methods Fourteen flock-rebuilding pathways were assessed for up to nine flock types, using a spreadsheet model that tracked inventory, cashflow, profit and loss, and the overall balance sheet over 5 years. Key results The top four pathways for profitability and capacity to rapidly rebuild flock numbers include retention of more older ewes, purchasing young ewes, purchasing older ewes (mostly 5–6-year olds) in Merino and Merino-cross flock types only and joining ewe lambs in Maternal and Cleanskin flock types only. These pathways were not sensitive to variation in the cost of supplementary feed, stock prices or flock structure, although joining Merino ewe lambs became one of the top four pathways when feed costs were lower. Conclusions and implications The well established practices of retaining ewes for longer and purchasing ewes, especially young ewes, have the most potential to both rapidly and profitably rebuild flock numbers. However, joining ewe lambs, particularly in Maternal and Cleanskin flocks, can also profitably contribute to rapid flock rebuilding. While reducing reproductive wastage or increasing reproductive potential were mostly profitable, they could not rapidly rebuild flock numbers. In contrast, accelerated lambing systems can rapidly rebuild flock numbers, but are only marginally profitable.

A comparative study of nominal group systems and structures between
Lhasa Tibetan and Mandarin Chinese
Authors: Wang Pin 
Published: May 2023

Abstract
This paper presents a text-based comparative study of the
construal of entities through nominal groups in Lhasa Tibetan and Mandarin
Chinese. It approaches the grammatical description of nominal groups from the
ideational and textual perspectives, and gives priority to the perspective “from
above”, taking as point of departure the discourse semantic systems of
ideation and identification. From the perspective of
ideation, the comparison focuses on the classification, description
and quantification of entities. From the perspective of identification,
the comparison focuses on the presentation or presumption of entities in
discourse, and the determination and qualification of them. In terms of
grammatical realisations, the nucleus function of a nominal group, Thing, enters
into multivariate structures with a range of pre- and post-Thing functions.
However, configuration and realisation of the functions are language-specific.
This study makes explicit structural consequences of systemic choices in nominal
group grammar, and attends to the problem of structural markers, drawing on the
notion of “subjacency” structure proposed in Martin et al. (2021) and Martin and Doran (this issue).
On Metapragmatic Gaslighting: Truth and Trump’s Epistemic Tactics in a Plague Year
Authors: Donzelli Aurora 
Published: May 2023

AbstractThis article focuses on the nexus between political discourse and contemporary concerns about the arbitration of truth to argue that Trump’s way of using speech about speech (i.e., his metapragmatic discourse) resembles the manipulation tactic commonly called gaslighting. Based on examples drawn from 2020 (i.e., White House press conferences and electoral presidential debates), I explore Trump’s metapragmatic gaslighting both as an epistemic tactic for the manipulation of information and as an effective style of political self-presentation. By analyzing specific instances of Trump’s metapragmatic commentaries that blatantly contradict shared pragmatic principles for the interpretation of utterances’ illocutionary force and denotational content, I show how Trump is able to present himself as a champion of semantic and moral candor and simultaneously promote a highly personalist view of the meaning-making process. In so doing, I also propose a metapragmatic approach to the epistemological and political predicaments posed by the “post-truth” epistemic regime.
Language and Neoliberalism in the Online Cosmetic Sample Business
Authors: Dou Gloria Yan 
Published: May 2023

AbstractThis article presents a digital ethnographic study of amateur entrepreneurs who sell cosmetic samples primarily in an online marketplace in Hong Kong to illustrate how they use language to to create added value in their unconventional beauty product niche. It examines how these people cross over to an authoritative and professional brand persona by reappropriating product description of the original products to introduce their own beauty sample products to a wide audience, forming interdiscursive links between the original brand and their own business. These linguistic and semiotic resources afforded by the online platforms help create extra value in the normally not-so-expensive cosmetic sample products being (re)sold by ordinary, unauthorized people. The marketing decision and invested labor of these amateur entrepreneurs display their neoliberal selfhoods, illustrating the precarious nature of their online business. This study offers unique insight into current research about the authenticity and commodification of language.
Emergent anomalous transport and non-Gaussianity in a simple mobile–immobile model: the role of advection
Authors: Doerries Timo J , Metzler Ralf , Chechkin Aleksei V 
Published: May 2023

Abstract
We analyse the transport of diffusive particles that switch between mobile and immobile states with finite rates. We focus on the effect of advection on the density functions and mean squared displacements (MSDs). At relevant intermediate time scales we find strong anomalous diffusion with cubic scaling in time of the MSD for high Péclet numbers. The cubic scaling exists for short and long mean residence times in the immobile state

the plateau in the MSD at intermediate times, previously found in the absence of advection, also exists for high Péclet numbers. Initially immobile tracers are subject to the newly observed regime of advection induced subdiffusion for short immobilisations and high Péclet numbers. In the long-time limit the effective advection velocity is reduced compared to advection in the mobile phase. In contrast, the MSD is enhanced by advection. We explore physical mechanisms behind the emerging non-Gaussian density functions and the features of the MSD.

Authors: Kumar Rohit , Manchaiah Dixith , Easwaran Raghavan K 
Published: May 2023

Abstract
In this manuscript, we have theoretically studied the four level closed loop atomic systems in the presence of two vector beams. A spatially dependent transparency for the probe vector beam is obtained based on the semiclassical model. We have explicitly shown that the number of petals formed for probe absorption depends on the value of orbital angular momentum (OAM) of the constituting beams. A detailed study for absorption and dispersion of right circularly polarized (RCP) and left circularly polarized (LCP) components of the probe beam is carried out and the importance of the polarization state of the beams on Higher Order Poincare Sphere (HOPS) is highlighted. An explicit effect of the interferometer phase of the vector beam which is geometric in nature, is shown for probe beam response. Three types of four level closed loop atomic system is studied with particular emphasis given for double Λ and Diamond atomic system. A dark state analysis of the atomic system is carried out which facilitate a physical understanding of the obtained results. Our study has explored the effects of inhomogeneity in both polarization and intensity for probe and coupling beam in a closed loop atomic system which is phase dependent.
Mid-infrared broadband metamaterial absorber based on van der Waals material
Authors: Liu Haotuo , Hu Yang , Ma Mingyi , Liu Meng , Ai Qing , Xie Ming , Wu Xiaohu 
Published: May 2023

Abstract
Van der Waals materials, such as α-phase molybdenum trioxide (α-MoO3), have promising prospects in modern optics technologies, such as nano-imaging, negative refraction, and infrared detection. Particularly, the natural hyperbolic properties of α-MoO3 make it an excellent candidate for perfect absorber. Here, we propose a design method for achieving broadband absorption based on van der Waals material (α-MoO3) in the mid-infrared band. The segmented cubic Hermite interpolation is used to generate various geometric structures. Numerical results show that the average spectral absorptance of the optimized structure is up to 0.993 in the wavelength range of 10.4–12.7 μm. The high absorption performance can be explained as the slow-light effect. The impact of incident angle on absorption performance is also investigated. Finally, we calculate the spectral absorptance of the proposed absorber when the crystal axes of α-MoO3 are rotated in the x-y plane. Our findings pave a novel path for designing broadband absorbers based on van der Waals materials, particularly in the mid-infrared band.
Modeling and complexity analysis of a fractional-order memristor conservative chaotic system
Authors: Leng Xiangxin , Zhang Limeng , Zhang Chenkai , Du Baoxiang 
Published: May 2023

Abstract
Memristors are often utilized in circuit model analysis as one of the fundamental circuit components. In this paper, a five-dimensional conservative memristor chaotic system is built after the introduction of the memristor into a four-dimensional conservative chaotic system. The dynamic changes of the system are examined using phase diagram, mean value, and Lyapunov exponent spectrum. A line equilibrium point, symmetry and multi-stability are characteristics of the system; the phase trajectory can also produce shrinking and structure transformation behavior with the change of parameters. Furthermore, the system has initial offset boosting behaviors, conservative flows of it can be altered in position by changing two initial values, respectively. Most notably, we discover that the complexity of the system rises with the inclusion of memristor and again with the addition of fractional differential operators. It is shown that the complexity of chaotic systems may increase with the addition of memristors and fractional-order differential operators. At last, the NIST is used to test the randomness of the sequence, and the system's physical realizability is confirmed by the DSP platform.
Remote targeted electrical stimulation
Authors: Webb Taylor , Cheeniyil Rahul , Wilson Matthew , Kubanek Jan 
Published: May 2023

Abstract

Objective: The ability to generate electric fields in specific targets remotely would transform manipulations of processes that rest on electrical signaling. Approach: This article shows that focal electric fields are generated from distance by combining two orthogonal, remotely applied energies—magnetic and focused ultrasonic fields. The effect derives from the Lorentz force equation applied to magnetic and ultrasonic fields. Main results: We elicited this effect using standard hardware and confirmed that the generated electric fields align with the Lorentz equation. The effect significantly and safely modulated human peripheral nerves and deep brain regions of non-human primates. Significance: This approach opens a new set of applications in which electric fields are generated at high spatiotemporal resolution within intact biological tissues or materials, thus circumventing the limitations of traditional electrode-based procedures.
Statistical ensembles for phase coexistence states specified by noncommutative additive observables
Authors: Yoneta Yasushi , Shimizu Akira 
Published: May 2023

Abstract
A phase coexistence state cannot be specified uniquely by any intensive parameters, such as the temperature and the magnetic field, because they take the same values over all coexisting phases. It can be specified uniquely only by an appropriate set of additive observables. Hence, to analyze phase coexistence states the statistical ensembles that are specified by additive observables have been employed, such as the microcanonical and restricted ensembles. However, such ensembles are ill-defined or ill-behaved when some of the additive observables do not commute with each other. Here, we solve this fundamental problem by extending a generalized ensemble in such a way that it is applicable to phase coexistence states that are specified by noncommutative additive observables. We prove that this ensemble correctly gives the density matrix corresponding to phase coexistence states of general quantum systems as well as the thermodynamic functions. Furthermore, these ensembles are convenient for practical calculations because of their good analytic properties and useful formulas by which temperature and other intensive parameters are directly obtained from the expectation values of the additive observables. As a demonstration, we apply our formulation to a two-dimensional system whose phase coexistence states are specified by an additive observable (order parameter) that does not commute with the Hamiltonian.
A local algorithm and its percolation analysis of bipartite z-matching problem
Authors: Zhao Jin-Hua 
Published: May 2023

Abstract
A z-matching on a bipartite graph is a set of edges, among which each vertex of two types of the graph is adjacent to at most 1 and at most z (

⩾
1

) edges, respectively. The z-matching problem concerns finding z-matchings with the maximum size. Our approach to this combinatorial optimization problem is twofold. From an algorithmic perspective, we adopt a local algorithm as a linear approximate solver to find z-matchings on any graph instance, whose basic component is a generalized greedy leaf removal procedure in graph theory. From a theoretical perspective, on uncorrelated random bipartite graphs, we develop a mean-field theory for the percolation phenomenon underlying the local algorithm, leading to an analytical estimation of z-matching sizes on random graphs. Our analytical theory corrects the prediction by belief propagation algorithm at zero-temperature limit in (Kreačić and Bianconi 2019 Europhys. Lett.
126 028001). Besides, our theoretical framework extends a core percolation analysis of k-XORSAT problems to a general context of uncorrelated random hypergraphs with arbitrary degree distributions of factor and variable nodes.
On the Solved Turbulent Scales in Turbulent Plume Fires
Authors: Ciani F.S. , Bonfiglio P. , Piva S. 
Published: May 2023

Abstract
Plume fires are characterized by a turbulent nature with a large number of different scales. LES is often used to solve the largest structures and to model the smallest ones. Grid size and time steps become decisive to place the limit between resolved and modelled turbulence. Significant information on this limit and its placement can be obtained with spectral analyses of the specific turbulent kinetic energy. While frequency analysis is relatively easy, an analysis in the wavenumber domain is more challenging. The IWC method, typically used in structures and acoustics, is used here for this purpose. IWC method allows to obtain wavenumber spectra with a better resolution than those obtained with a direct approach. Furthermore, in this paper the IWC method is also used in its reverse form to obtain frequency spectra. Although rather dense grids have been chosen, the number of nodes along the plume and their spacing is not such as to guarantee detailed wavenumber spectra with the direct approach and consequently with the reverse IWC. On the contrary, the IWC method provides wavenumber spectra in agreement with those obtained directly, but of much higher quality.

Published: May 2023

Abstract
Computational Fluid-Dynamics (CFD) simulations are widely used for designing components and devices for heat transfer enhancement, and to this end the Reynolds Averaged Navier-Stokes (RANS) equations are often chosen, as they are computationally efficient. In this paper, several numerical simulations have been carried out on convective heat transfer of an air flow through a rectangular channel of 1:10 aspect ratio, 120 mm wide, 840 mm long. Numerical results have been compared to analytical values and experimental data. The configuration of the described numerical model will be used as starting point for detailed investigations of fluid-dynamic and thermal performances of ribbed channels in further analysis.
An exhaustive search optimization of heat transfer and pressure drop in Kelvin’s open cell foams

Published: May 2023

Abstract
Thanks to their high effective thermal conductivity, specific surface area, and tortuosity, open-cell foams are well-known for their capability to enhance heat transfer in applications such as heat exchangers and volumetric solar air receivers. In the very recent years, innovative manufacturing techniques, including 3D designing and printing, have been looked very helpful to find foam morphologies that allow to maximize heat transfer and minimize pressure drop. Optimal foam structures can be obtained by means of pore-scale simulations, employing an exhaustive search with a bearable computational effort. A multi-objective optimization of convective heat transfer and pressure drop in Kelvin’s foams with air is presented in this paper. A pore-scale numerical model, with a uniform heat flux at the solid/fluid interface, is used to predict the interfacial convective heat transfer coefficient, hc
, and pressure drop, Δp, in the foam. The cell size, porosity, cell anisotropy stretching factor, as well as the inlet velocity and the direction of the air, are assumed as the design variables for the optimization model, while the interfacial convective heat transfer coefficient and pressure drop are chosen as the objective functions to be maximized and minimized, respectively. Pareto fronts ranging from h = 110 W/m2 K and Δp = 0.77 Pa to hc = 460 W/m2 K and Δp = 51 Pa are predicted, within which the optimum point for the chosen foam morphology, air velocity and direction can be selected, according to the chosen criterion.
Boundary element method for contactless estimation of spatially varying internal heat transfer coefficient in circular pipes
Authors: Aimi Alessandra , Bozzoli Fabio , Cattani Luca , Guardasoni Chiara 
Published: May 2023

Abstract
In the present study it is proposed a solution approach of the Inverse Heat Conduction Problem (IHCP) intended at assessing the local heat transfer coefficient on the inner wall of a tube, under a forced convection problem. The estimation method is established on the Boundary Element Method (BEM) combined with the Truncated Singular Value Decomposition (TSVD) methodology, employed to manage the ill-conditioned nature of the problem. The numerical results of the direct problem, built by the BEM, are firstly validated, and consequently adopted as synthetic data inputs to resolve the IHCP and corroborate the whole assessment procedure. This approach is also tested with experimental data about forced convection problem in coiled pipes. In these geometries, the convective heat transfer coefficient changes considerably along the wall periphery and for this reason, it constitutes a perfect example to test the ability of the presented method to infer a spatially varying internal heat transfer coefficient distribution.
