Proteomic Study of Middle Ear Effusion and Its Clinical Application for Otitis Media with Effusion.

Proteins found in middle ear effusion play crucial roles in the physiological and pathological processes of otitis media with effusion (OME), influencing the etiology and clinical characteristics of this disease. The qualitative and quantitative composition of these proteins depending on the underlying pathogenesis of middle ear effusion. Understanding their physiological and pathological functions is of great importance. We collected samples from 19 volunteers diagnosed with OME. After offline separation using high-pH reversed-phase liquid chromatography (RPLC), the pooled sample was subjected to LC-MS/MS analysis to obtain a comprehensive profile of the OME proteome. Functional analysis was performed using Gene Ontology (GO), Kyoto Encyclopedia of Genes and Genomes (KEGG), and Ingenuity Pathway Analysis (IPA) annotations. Data-independent acquisition (DIA) technology was utilized to analyze samples and fix whether the OME proteome could replicate the pathophysiological features associated with this disease. We conducted a differential proteomic analysis between patients with simple OME and patients who had received radiotherapy. The radiotherapy-reduced group was further divided into two subgroups: nasopharyngeal carcinoma (NPC) and other types of carcinoma. Parallel reaction monitoring (PRM) technology was used for validation of 36 differentially expressed proteins (DEPs). A number of 732 proteins were identified in the OME proteome database. Among them, 527 proteins were quantified using peak intensity-based semi-quantification (iBAQ), covering a wide dynamic range of approximately 8 orders of magnitude. Based on the functional analysis, we proposed a hypothetical mechanism of OME. This study managed to put up an inclusive analysis of the OME proteome, establishing the first human OME proteome database. We focused on differential proteomic analysis among different groups to gain a more comprehensive concept of the OME proteome and search for meaningful biomarkers.

Role of Pesantren in Da'wah and Media Literacy

This study aims to explore the process of media literacy in the Karangasem Islamic Boarding School and Al-Ishlah Islamic Boarding School in Lamongan Regency, East Java, as an effort to mitigate the spread of Covid-19. In the context of the pandemic, pesantren plays an important role in increasing the awareness of students and the public about health protocols through the development of media literacy. The research method used is a qualitative approach with data collection techniques in the form of in-depth interviews, observations, and documentation. The results of the study show that the two Islamic boarding schools have implemented an effective media literacy program, in which the Karangasem Islamic Boarding School through the INFOKOM program and the Al-Ishlah Islamic Boarding School with their journalistic activities, have succeeded in equipping students with critical skills in accessing and evaluating information. This study concludes that media literacy in Islamic boarding schools not only contributes to improving students' understanding of Covid-19, but also serves as a means to disseminate accurate information to the public, thus playing a role in mitigating the spread of the virus. This finding is expected to be a model for other Islamic boarding schools in developing media literacy in the digital era, especially in the context of public health.

Standing out from the crowd: When and why color complexity in social media images increases user engagement

Firms increasingly rely on images to drive user engagement with their social media content. However, evidence is limited on when and why image characteristics can draw social media users’ attention and increase engagement. In this research, the authors theorize that color complexity in images can serve as an external cue that draws social media users’ attention and provokes a shift from the peripheral processing mode to the central processing mode. This shift can result in deeper processing of the social media post that features the image, thus increasing the likelihood of the users’ engagement with the post. They further reveal heterogeneity in the effect of color complexity due to the time of day when the users are exposed to the image, image height, and sentiment and complexity in the text accompanying the image. The results are consistent across an empirical analysis of two proprietary Facebook datasets from distinct industries and time periods and confirmed by two biometric eye-tracking experiments that provide process evidence. The findings have important implications for both content marketers and academics as they seek to identify content features that can maximize user engagement on social media.

Reflections of COVID-19 virus on early childhood drawings

This research is aimed to investigate the COVID-19 virus reflections in the drawings by children in early childhood. The research was conducted with 30 (K15, E=15) children who volunteered to participate in the study from Batman provincial center in the academic year 2022-2023. In the research, the working group was determined according to the sampling criterion. In this regard, the criteria of "being in early childhood", "residing in Batman province", and "volunteering to participate in the study" were formed and taken into account in the research. In the research, the children were asked "What does the COVID-19 virus look like to you, can you draw a picture of it for me?", the picture was drawn by giving the instruction, and the data were collected by taking the story of the picture in the question. The obtained data were analyzed using QSR NVivo 10 computer program, which is suitable for qualitative data analysis. Descriptive analysis technique was used in the analyses. As a result, it has been seen that fear and anxiety are included in the children's pictures, they place public spots such as wearing masks and social distancing. Realism is included in the picture, the virus is depicted in red and green colours, but in shape it is the same in all children's pictures, which shows that this situation is also active in the isolation process of the press media.

Percolation and conductivity in evolving disordered media.

Percolation theory and the associated conductance networks have provided deep insights into the flow and transport properties of a vast number of heterogeneous materials and media. In practically all cases, however, the conductance of the networks' bonds remains constant throughout the entire process. There are, however, many important problems in which the conductance of the bonds evolves over time and does not remain constant. Examples include clogging, dissolution and precipitation, and catalytic processes in porous materials, as well as the deformation of a porous medium by applying an external pressure or stress to it that reduces the size of its pores. We introduce two percolation models to study the evolution of the conductivity of such networks. The two models are related to natural and industrial processes involving clogging, precipitation, and dissolution processes in porous media and materials. The effective conductivity of the models is shown to follow known power laws near the percolation threshold, despite radically different behavior both away from and even close to the percolation threshold. The behavior of the networks close to the percolation threshold is described by critical exponents, yielding bounds for traditional percolation exponents. We show that one of the two models belongs to the traditional universality class of percolation conductivity, while the second model yields nonuniversal scaling exponents.

Trends in media development in Ukraine: Social communication and legal aspects

Globalisation and the development of new trends lead to the emergence of innovative tools for influencing the public; today, such tools are the mass media. Media is an important element of interaction between the authorities and society in the context of forming the necessary opinion on events and phenomena occurring in a particular historical period. The purpose of the study is to investigate the features and specifics of the functioning of mass media in Ukraine by examining the social communication and legal aspects of media activity in a historical context. The main method of research was the system and analytical method, by which the key characteristics and basic signs of the dynamics of the formation and development of Ukrainian media are considered, the specifics of the process of media influence on public opinion in Ukraine are outlined, and the prospects for the development of the direction in the future are presented. The essence and content of the concept of mass media, the history of its origin and general global trends in the development of the direction were analysed. The characteristic features of the transformation of the media sphere in independent Ukraine are identified, and the basic features and trends of the main types of media are summarised. The level and intensity of influence of certain media tools on public opinion in Ukraine were investigated. Based on the results obtained, the prospects for the evolution of mass media in Ukraine in the future are outlined; the main threats and challenges to further development in the context of the transformation of the social and communication sphere of social development are listed. The results and conclusions of this study can be used as a basis for future research on the presented topic, in particular, in the specialities “Sociology”, “Economics”, “Law”, as well as during the development and implementation of the legal framework in the field of regulating media activities in the social and cultural life of the state.

Numerical Analysis of Direct and Inverse Problems for a Fractional Parabolic Integro-Differential Equation

A mathematical model consisting of weakly coupled time fractional one parabolic PDE and one ODE equations describing dynamical processes in porous media is our physical motivation. As is often performed, by solving analytically the ODE equation, such a system is reduced to an integro-parabolic equation. We focus on the numerical reconstruction of a diffusion coefficient at finite number space-points measurements. The well-posedness of the direct problem is investigated and energy estimates of their solutions are derived. The second order in time and space finite difference approximation of the direct problem is analyzed. The approach of Lagrangian multiplier adjoint equations is utilized to compute the Fréchet derivative of the least-square cost functional. A numerical solution based on the conjugate gradient method (CGM) of the inverse problem is studied. A number of computational examples are discussed.

IDENTIFICATION OF SEPARATION CURVES OF STRONGLY CONTRASTING ENVIRONMENTS USING COMPLEX ANALYSIS METHODS

When modeling mass transfer processes (for example, filtration) in porous media, there may be cases of the existence of highly permeable layers, which are separated from the corresponding studied parts by some curves that must be found (identified) in the process of solving the problem. When constructing a mathematical model of the corresponding physical process, we will consider a highly permeable medium as "ideally (theoretically infinitely) permeable." In this case, the desired curve can be considered an equipotential line. This work considers the stationary process of fluid movement in a homogeneous horizontal layer of infinitely large dimensions - a soil massif, which is limited by infinite sections of curves, in particular by the desired curve of theoretical water resistance and the horizontal axis, on which the local speed of movement is known. On the basis of the methods of conformal reflections and total images, an approach to the identification of the curve of the separation of media is proposed. The constructed algorithm is modified for solving nonlinear inverse boundary value problems on quasi-conformal mappings of curvilinear polygonal regions bounded by uncertain streamlines and equipotential lines. The feature of the method proposed is that the summary representation formulae allow to explicitly write the solution to the localized linear (main) part of the obtained system of equations. The unknown coefficients are determined here by solving a non-linear system generated solely by the boundary conditions and numerical analogues of the Cauchy–Riemann equations.

Unraveling the Phase Transition Behavior of MgMn2O4 Electrodes for Their Use in Rechargeable Magnesium Batteries.

Rechargeable magnesium batteries are an attractive alternative to lithium batteries because of their higher safety and lower cost, being spinel-type materials promising candidates for their positive electrode. Herein, MgMn2O4 with a tetragonal structure is synthesized via a simple, low-cost Pechini methodology and tested in aqueous media. Electrochemical measurements combined with in-situ Raman spectroscopy and other ex-situ physicochemical characterization techniques show that, in aqueous media, the charge/discharge process occurs through the co-intercalation of Mg2+ and water molecules. A progressive structure evolution from a well-defined spinel to a birnessite-type arrangement occurs during the first cycles, provoking capacity activation. The concomitant towering morphological change induces poor cycling performance, probably due to partial delamination and loss of electrical contact between the active film and the substrate. Interestingly, both MgMn2O4 capacity retention and cyclability can be increased by doping with nickel. This work provides insights into the positive electrode processes in aqueous media, which is vital for understanding the charge storage mechanism and the correlated performance of spinel-type host materials.

Statistical Effective Diffusivity Estimation in Porous Media Using an Integrated On-site Imaging Workflow for Synchrotron Users

Transport in porous media plays an essential role for many physical, engineering, biological and environmental processes. Novel synchrotron imaging techniques and image-based models have enabled more robust quantification of geometric structures that influence transport through the pore space. However, image-based modelling is computationally expensive, and end users often require, while conducting imaging campaign, fast and agile bulk-scale effective parameter estimates that account for the pore-scale details. In this manuscript we enhance a pre-existing image-based model solver known as OpenImpala to estimate bulk-scale effective transport parameters. In particular, the boundary conditions and equations in OpenImpala were modified in order to estimate the effective diffusivity in an imaged system/geometry via a formal multi-scale homogenisation expansion. Estimates of effective pore space diffusivity were generated for a range of elementary volume sizes to estimate when the effective diffusivity values begin to converge to a single value. Results from OpenImpala were validated against a commercial finite element method package COMSOL Multiphysics (abbreviated as COMSOL). Results showed that the effective diffusivity values determined with OpenImpala were similar to those estimated by COMSOL. Tests on larger domains comparing a full image-based model to a homogenised (geometrically uniform) domain that used the effective diffusivity parameters showed differences below 2 % error, thus verifying the accuracy of the effective diffusivity estimates. Finally, we compared OpenImpala’s parallel computing speeds to COMSOL. OpenImpala consistently ran simulations within fractions of minutes, which was two orders of magnitude faster than COMSOL providing identical supercomputing specifications. In conclusion, we demonstrated OpenImpala’s utility as part of an on-site tomography processing pipeline allowing for fast and agile assessment of porous media processes and to guide imaging campaigns while they are happening at synchrotron beamlines.

Alterations in wettability and immiscible fluid flows by bacterial biosurfactant production for microbial enhanced oil recovery: Pore-scale micromodel study

This study investigates alterations in wettability during bacterial growth and biosurfactant production and its ensuing impacts on immiscible fluid flow at a pore scale. Here, pore-scale experiments were carried out with two types of patterned micromodels. First, the experiments with a single-channel micromodel visually captured the real-time wettability alteration from oil-wet to water-wet while cultivating the model bacteria Bacillus subtilis, in which the bacterial cells and produced biosurfactant significantly lowered the contact angles, including static, advancing, and receding angles, by ∼70–90°. In addition, the emulsification-demulsification phenomena at brine-oil interfaces and the contact angle alterations by biofilms were also observed. Second, the surfactant-flooding process was emulated in the experiments with multi-channel micromodel while examining the effect of surfactant concentration on oil sweeping efficiency. The results of the multi-channel micromodel experiment show that a biosurfactant concentration of 70 mg/L, which is twice the critical micelle concentration, resulted in a lower contact angle, reduced residual oil saturation, and more homogeneous and stable patterns of oil displacement. Particularly, a significant level of variations in the contact angles at fluid-solid interfaces was observed in the multi-channel micromodel, and the extent of variation decreased with an increase in biosurfactant concentration. The presented results provide insights into pore-scale coupled microbial-hydrological processes in porous media as well as the biosurfactant-aided flooding in microbial enhanced oil recovery (MEOR).

Insights into microwave assisted synthesis of spiro-chromeno[2,3-d]pyrimidines using PEG-OSO3H catalyst: DFT study and their antiproliferative activity

Herein, we established an environmentally benign green approach for the synthesis of new spirochromeno[2,3-d]pyrimidines. PEG-4000-OSO3H catalysed microwave-assisted multicomponent reaction of sesamol, isatin and barbituric acid enables us to produce spirochromeno[2,3-d]pyrimidines. This approach is notable for its eco-friendly polymer catalyst, rapid metal-free synthesis, easy workup, higher yield (88–97%), no need for column chromatographic purification and outstanding green credential parameters of the process. The use of harmless solvents, microwave process and reusability of reaction media made the present protocol sustainably effective from a green perspective. The molecular structure of 4j was confirmed by Single crystal XRD analysis and their DFT study was carried out. To gain insight into the molecule's geometry and physicochemical properties, quantum chemical density functional theory was employed at B3LYP/6–31G(d, p) basis set. Furthermore, all compounds were examined for antiproliferative activity against six solid human tumour cell lines. Compounds 4j and 4k exhibit excellent potency against T-47D (breast) and WiDr (colon) cell lines as compared to the standard drug cisplatin (CDDP). The most potent compound is 4j, which exhibits GI50 values in the range 5.2–11 µM against all cell lines.

Suitability of body force model for pressure-difference driven flow in porous media

Pore-scale direct numerical simulation is an important tool for studying the flow of porous media nowadays. This work validates the suitability of body force model for simulating pressure-difference-driven porous flows in pore-scale simulations. The multi-relaxation time lattice Boltzmann method (MRT-LBM) with the color-gradient continuum-surface-force (CG-CSF) model is employed to calculate the absolute and relative permeability of randomly generated porous media. Results show that for single-phase flows, the relative errors are below 5% for most homogeneous porous structures while as high as 80% for structures with preferential paths. This study also reveals the pore-scale flow mechanisms and proposes a new heterogeneity parameter quantified by the standard deviation of the pressure at the boundary. For multiphase flows, errors of the body force model are significant at low Ca due to irreversible phase distribution difference appearing at the early stages. The findings of this work could be applied to other transport processes in porous media. It is crucial to consider the structural heterogeneity and proper parameters when employing the body force model in pore-scale simulations.

European French-Speaking Local Media’s Relationship with Audiences. A Strategic Challenge between Diluted and Integrated Organizational Modalities

This article studies local news media’s relationship with audiences from an organizational perspective. It is based on 45 semi-structured interviews conducted in eleven local news organizations in European French-speaking countries (France, Switzerland and Belgium), that explored the implementation of actions aiming at revitalizing the link with audiences, the role of the hierarchy and the allocation of human and material resources to this end. Findings reveal two organizational modalities that characterize how the issue of audiences is taken into account in local news media. A proactive and integrated modality describes news media that tend to include the issue of audiences in the internal organization in a tangible, visible and structured way. A reactive and diluted modality describes news media that tend to favor a more variable and opportunistic approach to audience relations. This typology, built empirically from our data, does not claim to situate a news outlet in a definitive manner, but rather suggests a reading grid for questioning the degree of formalization of the issue of audiences within the organizational process of local news media.

Inverse modeling of nonisothermal multiphase poromechanics using physics-informed neural networks

We propose a solution strategy for parameter identification in multiphase thermo-hydro-mechanical (THM) processes in porous media using physics-informed neural networks (PINNs). We employ a dimensionless form of the THM governing equations that is particularly well suited for the inverse problem, and we leverage the sequential multiphysics PINN solver we developed in previous work. We validate the proposed inverse-modeling approach on multiple benchmark problems, including Terzaghi's isothermal consolidation problem, Barry-Mercer's isothermal injection-production problem, and nonisothermal consolidation of an unsaturated soil layer. We report the excellent performance of the proposed sequential PINN-THM inverse solver, thus paving the way for the application of PINNs to inverse modeling of complex nonlinear multiphysics problems.
