    Raspberry Pi multispectral imaging camera system (PiMICS) : a low-cost, skills-based physics educational tool
    Howell, John C.; Flores, Brian; Naranjo, Juan Javier; Mendez, Angel; Costa-Vera, Cesar; Koumriqian, Chris; Taormina, Nathan; Jordan, Juliana; Neethling, Pieter H.; Groenewald, Calvin; Lovemore, Michael A.C.; Kinsey, Patrick A.T.; Kruger, T.P.J. (Tjaart) (American Association of Physics Teachers, 2026-02)
    Here, we report on a skills-building 3D-printable, Raspberry Pi-based multispectral camera (15–25 spectral channels in the visible and near-IR) for as little as $150–$300. The cameras rely on measuring the reflectance spectra of various objects using both active and passive illumination. The cameras were used in a successful pilot program designed such that students could learn 3D modeling, 3D printing, feedback, control, image analysis, Python programming, systems integration, and machine learning, as well as spectroscopy. The students in the pilot program studied a wide array of target spectra upon completion of their cameras, showing their aid as valuable research tools. We believe this can be an important instructional tool in introductory or advanced STEM laboratory courses.

    Queer(ed) avatars : exploring visual identity construction in final fantasy XIV online gaymers
    Van Heerden, Karl (Sage, 2026)
    I explore gaymers’ use of virtual photography to construct their avatar persona in Final Fantasy XIV Online. The study of game photography is a field that has seen relatively sparse engagement from scholars in the past decade. In this article, I discuss virtual photography's potential in gaymers’ visual construction of avatar personas in massively multiplayer online role-playing games. I focus on “gaymers” as they seek alternative identity affordances, expressing dissatisfaction with the narrow range of possibilities in games. In contextualizing the phenomenon, I engage with theories on virtual photography, persona studies, and social networking. I apply this theoretical framework to a series of Instagram accounts dedicated to FFXIV Online avatars. I incorporate a queer methodology in my research to expose how gaymers resist heteronormativity in games. My findings indicate that gaymers queer FFXIV Online's mechanics and visuals through modding and shaders to visually co-construct a digital self.

    Radicals in flip subalgebras of Matsuo algebras
    Rodrigues, Bernardo Gabriel; Shpectorov, S. (Springer, 2026-04)
    We develop methods for determining key properties (simplicity and the dimension of radical) of flip subalgebras in Matsuo algebras. These are interesting classes of commutative non-associative algebras that were introduced within the broader paradigm of axial algebras.

    Rapid commercial CTX-M diagnostics : performance, limitations and clinical impact
    Aldeia, Claudia; Peirano, Gisele; Pitout, Johann D.D.; Endimiani, Andrea (Springer, 2026-02)
    CTX-M enzymes account for more than 90% of all extended-spectrum β-lactamases (ESBLs) identified in Enterobacterales. Therefore, rapid identification of these enzymes could improve clinical outcomes in patients infected or colonized by such pathogens. In this review, we described the characteristics and limitations of commercially available rapid tests for detecting CTX-M proteins (lateral flow immunoassays) or blaCTX−M genes (microarrays, quantitative PCR, or loop-mediated isothermal amplification). Additionally, we summarized and discussed their potential clinical impact. Some commercial CTX-M assays - particularly those analyzing aliquots from positive blood cultures (i.e., Verigene, BioFire FilmArray, ePlex) - demonstrated clear advantages over standard-of-care methods, shortening the interval to effective therapy and improving overall patient outcomes. However, the widespread adoption of these rapid assays in routine laboratories remains limited due to several factors, including high costs and the lack of robust evidence supporting their positive impact. To address these implementation challenges, laboratories should focus on a defined patient subgroup in whom the application of these assays is likely to yield the greatest clinical impact. In particular, we propose that all laboratories at least perform rapid CTX-M assays on all Gram-negative-positive blood cultures (including those with sterile fluids) obtained from critically ill patients, such as ICU-patients with septic shock. This strategy is best when accompanied by active communication between the laboratory and key stakeholders in patient management. Providing rapid results for this subpopulation of patients may facilitate timely initiation of appropriate therapy and ultimately improve patient outcomes.
