Fluid stretching in porous media governs the mixing of reactants, contaminants, and nutrients, yet how the solid microstructure controls the stretching statistics remains poorly understood. We investigate how porous-medium heterogeneity controls stretching using (i) particle-tracking velocimetry experiments in 3D-printed millifluidic cells, (ii) numerical simulations of solute-plume deformation in the measured flow fields, and (iii) analytical calculations of fluid stretching. The cells contain arrays of cylindrical rods with systematically-varying disorder levels, from ordered to random. Velocity and shear-rate measurements reveal that fluid deformation is strongly localized near solid boundaries for all disorder levels, suggesting that near-wall flow is the main driver of stretching. The mean stretching grows linearly in time for ordered media and quadratically for disordered media, while the stretching distributions are approximately log-normal. We analytically describe the stretching produced by flow around an isolated cylinder and embed this description in a random-walk model that reproduces the observed stretching statistics in random media. These results provide the first quantitative connection between porous-medium structure and fluid-stretching statistics, revealing the extent to which disordered media accelerate mixing relative to ordered media and enabling progress beyond the common mean-field description of stretching in two-dimensional media as a simple shear flow.

Astronomy, a captivating field that draws upon science, mathematics, and engineering, has traditionally relied on visual representations to convey the wonders of the cosmos. While this approach effectively engages the sighted population, the use of imagery can exclude individuals with blindness or visual impairment (B/VI). Astronomical research is incorporated into press releases, media, outreach efforts, and educational systems aimed at enhancing public interest and often skill in science, but visual materials can hamper a population with B/VI. This paper explores the potential of 3D printing as an assistive technology providing an alternative to imagery. We produced textured 3D prints of astronomical research data from the Hubble Space Telescope (HST). Useability assessment of materials is an important phase of production before integration into structured programs, and we used a multi-phased approach in our prior research to create and test appropriate textures for 3D astronomical prints. This paper describes the last step of reviewing our 3D prints through informal useability sessions with diverse individuals. The assessment indicated our 3D prints provide reliable, informative representations of astronomical data appropriate for public use especially for public information, outreach programs, and science education for individuals with BVI.

Digital copiers and printers are widely used nowadays. One of the most important things people care about is copying or printing quality. In order to improve it, we previously came up with an SVM-based classification method to classify images with only text, only pictures or a mixture of both based on the fact that modern copiers and printers are equipped with processing pipelines designed specifically for different kinds of images. However, in some other applications, we need to distinguish more than three classes. In this paper, we develop a more advanced SVM-based classification method using four more new features to classify 5 types of images which are text, picture, mixed, receipt and highlight.

Language use offers valuable insight into affective disorders such as bipolar disorder (BD), yet past research has been cross-sectional and limited in scale. Here, we demonstrate that social media records can be leveraged to study longitudinal language change associated with BD on a large scale. Using a novel method to infer diagnosis timelines from user self-reports, we compared users self-identifying with BD, depression, or no mental health condition. The onset of BD diagnosis corresponded with widespread linguistic shifts reflecting mood disturbance, psychiatric comorbidity, substance abuse, hospitalization, medical comorbidities, interpersonal concerns, unusual thought content, and altered linguistic coherence. In the years following the diagnosis, discussions of mood symptoms were found to fluctuate periodically with a dominant 12-month cycle consistent with seasonal mood variation. These findings suggest that social media language captures linguistic and behavioral changes associated with BD and might serve as a valuable complement to traditional psychiatric cohort research.

In the context of rapid growth in the number of digital media and their audiences, the risks of online communication in medical practice represent a global problem: in highly digitalized countries, media become a public arena where discourses about the professionalism of medical workers are constructed, models for perceiving healthcare system issues are formed, and the terms of the social contract between society and representatives of the medical profession are debated. Aim. Based on the analysis of constructing social representations of physician competence in digital media, to identify criteria for evaluating competence and to outline the ethical and social consequences of mistakes in medical online communication. Methods. Using case study, narrative analysis, and content analysis methods, the study examines digital media print materials and user comments on Telegram and VKontakte regarding a regional case involving the mediatization of a doctor’s private video. The paper describes the components of the narrative constructed during online communication between media and users, and identified the main leitmotifs of the discourse in which the understanding of physician professionalism is formed. At the first stage, analysis of digital media materials (N=19) builds a narrative model jointly formed by authors and audiences. At the second stage, thematic content analysis of social network group user comments (N=863) identifies the main directions of discussion about the person and the doctor’s online communications. The study reveals the social foundations for assessing physician competence, its components, the conditions for its formation and control, and the context in which it is realized. The conclusion is that the understanding of online professionalism is jointly constructed by formal and informal actors involved in online communication, and includes clinical, moral‐ethical, and sociocultural components, which degree of development is linked to personal characteristics – age, work experience, and verbal and visual communication skills. The broad range of components included in the assessment also expands the list of institutional actors held responsible for violations of communication ethics.

The restoration of the Pirelli Skyscraper—necessitated after a notorious plane crash in 2002—became a key example of architectural intervention in modern architecture with heritage status. Even two decades after its completion, the process stands out for extraordinary research and analysis efforts—involving studying existing documentation, observing and measuring spaces, materials, and construction techniques. This ongoing investigation reaffirms that essentiality, as thought by Gio Ponti, remains a fundamental principle of architectural design until today. The intervention strategies of Corvino+Multari, accompanied by a technical and scientific team, have breathed life into Ponti’s masterpiece while stimulating a broader reflection on approaches to complex architectural monuments. Engaging critically with its architecture, the project positions itself between restoration and intervention, both philological in its approach and contemporary in spirit. The meticulous restoration of the curtain wall, fixtures, and mosaic tesserae exemplifies this.

Although printed transistors have a wide range of applications, the limited resolution of printing techniques (10-30 um) has been a barrier to advancement and scaling, particularly down to submicron dimensions. While previous works have shown creative approaches to realizing submicron channel lengths with printing, reliance on chemical processes unique to specific inks or tedious post-processing limit their applicability. Here, we report the use of capillary flow printing (CFP) to repeatably create fully printed submicron carbon nanotube thin-film transistors (CNT-TFTs) without chemical modification or physical manipulation post-printing. The versatility of this printing technique is demonstrated by printing conducting, semiconducting, and insulating inks on several types of substrates (SiO2, Kapton, and paper) and through the fabrication of various TFT device (contacting/gating) architectures. Notably, CFP of these CNT-TFTs yielded on-currents of 1.12 mA/mm when back gated on Si/SiO2, and 490 uA/mm when side gated through ion gel on Kapton, demonstrating the strong transistor performance achievable with CFP. Mechanical bending and sweep rate resilience of devices printed on Kapton show the wide utility of CFP-fabricated devices for flexible applications. This work highlights the ability of CFP as a viable fabrication method for submicron electronics through cleanroom-free printing techniques.

The unprecedented wildfires of 2017 in Portugal, particularly affecting the Centre Region, resulted in more than 100 deaths and numerous other dramatic socioeconomic and environmental impacts. Due to the unparalleled magnitude of these events, the extent of the burned area, and the catastrophic consequences, forest and fire management were placed at the center stage of public and political concerns, receiving wide mass media attention and amplification likely to shape public opinion and influence policy decisions. Through a quasi-qualitative content analysis approach, this article focuses on the media narratives conveyed by the news issued over two years (N = 1056) by eight newspapers of different periodicities and geographical scopes regarding the wildfires of October 2017 in the <i>Matas do Litoral</i>—coastal public-managed forest areas located in the Centre Region of Portugal. The analysis focuses on three main dimensions: the agents and actors mentioned and their power-related positions, the geographical coverage of the newspapers, and the relevance ascribed to emotions and feelings in the media narratives about the wildfires. The results demonstrate the relevance attributed in media narratives to the views of institutional agents and the negligence of local people’s voices. When particularly highlighting the material impacts of the wildfires, media narratives tended to focus less on people’s emotions and other non-tangible issues. The variation in these narratives according to the geographical scope of the newspapers and the publication time of the news strongly points out the need to address the heterogeneous character of the media coverage of wildfires.

Fashion is a primary need for society, especially teenagers. One way to look attractive is to wear clothes that follow the trend. Many clothing stores compete with certain promotional methods. Many strategies are used to promote products fashion one way is through the catalog. View catalog fashion presented in the form of print media may be commonly used in stores to describe products fashion to consumers. The purpose of this study is to generate applications that can be used to find out product models in detail by utilizing technology augmented reality. The observation method was carried out by collecting fashion product data from several fashion stores such as Erigo Store and Uniqlo CO. -The literature study approach is used by gathering information from various journals and papers from Google Scholar. With the Android-based application system using technology augmented reality as a promotional media for clothing sales, it can facilitate fashion products promotion for the stores and make it simpler for prospective customers to identify models and motifs and see the 3-dimensional shape of clothing products without needing to visit the retailer. From the outcomes of the black box testing that has been performed, the fashion catalog application uses augmented reality, is free from functional errors and is able to display all 3D objects of the product fashion which is already stored in the Vuforia database.

Light-based additive manufacturing holds great potential in the field of bioprinting due to its exceptional spatial resolution, enabling the reconstruction of intricate tissue structures. However, printing through biological tissues is severely limited due to the strong optical scattering within the tissues. The propagation of light is scrambled to form random speckle patterns, making it impossible to print features at the diffraction-limited size with conventional printing approaches. The poor tissue penetration depth of ultra-violet or blue light, which is commonly used to trigger photopolymerization, further limits the fabrication of high cell-density tissue constructs. Recently, several strategies based on wavefront shaping have been developed to manipulate the light and refocus it inside scattering media to a diffraction-limited spot. In this study, we present a high-resolution additive manufacturing technique using upconversion nanoparticles and a wavefront shaping method that does not require measurement from an invasive detector, i.e., it is a non-invasive technique. Upconversion nanoparticles convert near-infrared light to ultraviolet and visible light. The ultraviolet light serves as a light source for photopolymerization and the visible light as a guide star for digital light shaping. The incident light pattern is manipulated using the feedback information of the guide star to focus light through the tissue. In this way, we experimentally demonstrate that near-infrared light can be non-invasively focused through a strongly scattering medium. By exploiting the optical memory effect, we further demonstrate micro-meter resolution additive manufacturing through highly scattering media such as a 300-μm-thick chicken breast. This study provides a proof of concept of high-resolution additive manufacturing through turbid media with potential application in tissue engineering.

In the era of digitalization, social media has become an integral part of our lives, serving as a significant hub for individuals and businesses to share information, communicate, and engage. This is also the case for professional sports, where leagues, clubs and players are using social media to reach out to their fans. In this respect, a huge amount of time is spent curating multimedia content for various social media platforms and their target users. With the emergence of Artificial Intelligence (AI), AI-based tools for automating content generation and enhancing user experiences on social media have become widely popular. However, to effectively utilize such tools, it is imperative to comprehend the demographics and preferences of users on different platforms, understand how content providers post information in these channels, and how different types of multimedia are consumed by audiences. This report presents an analysis of social media platforms, in terms of demographics, supported multimedia modalities, and distinct features and specifications for different modalities, followed by a comparative case study of select European soccer leagues and teams, in terms of their social media practices. Through this analysis, we demonstrate that social media, while being very important for and widely used by supporters from all ages, also requires a fine-tuned effort on the part of soccer professionals, in order to elevate fan experiences and foster engagement.

Journalists are working in an ever-changing environment (where precarity has become commonplace). Reporters are increasingly required to multi-task, as news has become ubiquitous. This includes writing and editing copy, posting content online and on social media, sourcing images, recording and editing audio and recording pieces to camera: the traditional television, radio and print reporter all rolled into one. Yet, additional duties are not matched by increased pay; in some instances resources have been cut, and management cite reduced advertising revenue as the main reason. This research examined the impact of those changes to work practices on journalists, the media industry, and on wider society in Ireland, where multi-tasking has become more prevalent in the past 10 to 15 years and the pressures faced by journalists have intensified in the aftermath of COVID-19. Twelve journalists working in the media in Ireland were interviewed as part of this research. Their perceptions on the main influences on their work practices were explored. The findings of this research argue that due to the relentless drive for profit maximization, the result is that insufficient time and resources are made available to run newsrooms adequately and this is particularly prevalent in the regional press. This means ‘desk’ journalism is prioritized over ‘field’ reporting, while the battle between accuracy and immediacy is placing journalists under immense pressure and this also affects the quality of content produced and disseminated. Also, there is insufficient focus by media organizations on time intensive journalism i.e., investigative journalism—which potentially impacts everyone’s lives—and this influences how ordinary citizens understand the world around them. This research argues that the ability of journalism to hold the powerful to account is diminishing. Journalism, in its current trajectory, does not fulfil its Fourth Estate or ‘watchdog’ function, and critically, this influences people’s understanding of society, as this research outlines.

Objective: This paper aimed to identify and explore the major areas of health-sector corruption during COVID-19 pandemic as revealed in the print media. Findings are expected to mitigate health sector corruption in the country and contribute to strengthening the health systems. Method: 2588 news articles on health topics were identified through scanning six leading newspapers in Bangladesh during Mar. 2020 to Mar. 2021. Of these, 97 news articles focusing on corruption in health system were selected for analysis. Findings: Findings reveal an all-embracing corruption at every stage, starting from procurement of medical supplies, to testing for COVID-19 to treatment and management of COVID-19 cases. The news papers reported about the low quality and general-purpose masks given to the frontline health workers, putting their personal protection from the virus at risk. Due to lack of stewardship and an effective monitoring system, quite a few private facilities were providing fake COVID-19 certificates, medicines and medical equipment at very high prices. For example, one particular hospital provided almost two thousand COVID-19 test certificates without testing. Although PPEs were originally sold at BDT 2000 per piece, double the amount was proposed for buying PPEs. Meropenem injection of the same quality was purchased by different government hospitals at unusually high prices. Among the measures taken to contain corruption during COVID-19 included filing cases, issuing arrest warrants and asking for submission of wealth statement and source of income of the accused persons. However, some of the accused eventually got released on bail. Conclusion: The media, as a mirror of the society, successfully made visible the underhand corruption that was happening even during the pandemic, fulfilling its obligations to the society. They faced quite some challenges in revealing related news, especially from the government whose initial reaction was of denial and indifference.Due to lack of transparency and accountability in the sector, the patients as well as the healthcare providers had to suffer a lot.

Papyrus Berlin 8345, which comes from the Roman-period Fayum (Egypt), contains a Demotic astrological treatise aimed at foretelling an individual’s future based on the positions of the seven celestial bodies known in antiquity (Sun, Moon, Saturn, Jupiter, Mars, Venus, and Mercury) in the twelve places or compartments of the zodiac known as the dodecatropos. This paper briefly outlines the contents of the text and considers the conventions of textual division demonstrated in the papyrus. Since Demotic lacks modern punctuation, the scribe employed a host of other techniques to highlight and differentiate the various parts of the text. The manual was intended as a reference work, and the copyist therefore attempted to facilitate comfortable navigation through its different sections.
