No full textEnhancing audiovisual media experience with AI : insights from a pilot study on emotionally attuned subtitles for the d/Deaf and hard of hearing audiences
No full textThis article reports on a pilot study examining the role of emotionally expressive subtitles in improving the accessibility and inclusivity of audiovisual (AV) content for d/Deaf and Hard of Hearing audiences. Standard subtitling practices, although widely used, prioritize linguistic accuracy at the expense of conveying affective information crucial for narrative understanding. The study described here investigates alternative subtitling strategies that integrate visual design elements – such as dynamic typography, color, and motion - to reflect the emotional atmosphere of AV material. Drawing on multimodal theory and concepts from embodied cognition, the research explores how such subtitles may enrich a viewer’s experience by enhancing both comprehension and emotional engagement, particularly among audiences who rely on visual rather than auditory cues. Data were collected using an eye tracker and post-viewing questionnaires, which assessed participants’ perceptions of accessibility, narrative clarity, and affective resonance. While analysis of biometric measures remains ongoing, preliminary findings indicate that visually enriched subtitles may offer added value beyond conventional captioning methods. The study adds to growing interdisciplinary discourse on media accessibility, suggesting that emotionally attuned subtitling holds promise as a multimodal enhancement to traditional approaches, with implications for both practice and further research
Studying the outcomes and mechanisms of carbocationic rearrangements using algorithm‐augmented experimentation
No full textCarbocationic rearrangements are fundamental to both biosynthetic and synthetic chemistries, yet their high reactivity and mechanistic complexity often defy intuitive prediction of outcomes. Herein, HopCat, a hybrid algorithmic platform combining rule-based transformation logic with quantum-mechanically informed kinetics, is applied to explore the rearrangement networks of acid-catalyzed terpenoid transformations. Using a series of terpenoid substrates, an array of structurally diverse and unprecedented products is obtained. It is narated how HopCat can work synergistically with a human chemist to guide product assignment, downselect product candidates based on NMR cues, and reconstruct plausible, multistep mechanistic pathways, including those involving unanticipated intermediates
Studies of CPT symmetry in positronium decays with the 192 plastic strip J-PET detector
No full textA direct test of the CPT symmetry is performed for the electromagnetic decays of ortho-positronium using the Jagiellonian positron emission tomograph (J-PET). We present the precise measurement of the CPT-sensitive angular correlation entailing the positronium spin and the momenta of its annihilation photons, surpassing previous studies utilizing the same detection system. Positrons originating from a Na source are emitted from the detector’s center and subsequently form positronium atoms within the spherical chamber covered with porous material. Reconstruction of annihilation locations using the 192-strip J-PET detector makes it possible to determine the positronium emission direction, which defines the quantization axis along which positronium is polarized, without the application of external magnetic fields. The measurements were performed in total for 356 days resulting in an identification of 47.8 10 events with ortho-positronium decays into three photons. The results are consistent with the exactness of CPT symmetry with measured asymmetry amplitude -0.00029 ± 0.00022 (stat.) and with statistical error four times smaller than the previous best measurement
Frosted muzzles and digital bonds : embodied information practices and affective adoption in a crisis shelter ecology
No full textW niniejszym rozdziale przeanalizowano praktyki związane z informacją ucieleśnioną i afektywną, które pojawiły się podczas adopcji psów w ramach akcji "Frost Action 2024" w Polsce, spowodowanej kryzysem. Zbadano, w jaki sposób potencjalni adoptujący tworzyli mentalne i emocjonalne wyobrażenia o nieznanych psach ze schronisk na podstawie fragmentarycznych, nacechowanych emocjonalnie informacji udostępnianych w mediach społecznościowych. W tej sytuacji pilnej potrzeby świadomy wybór został zastąpiony wnioskami opartymi na relacjach i natychmiastową reakcją etyczną. Adoptujący opierali się na symbolicznych podpisach, fragmentach narracji i budzących emocje obrazach, aby stworzyć w umyśle obraz psa i podjąć działanie w oparciu o przewidywaną wzajemną wrażliwość. Wykorzystując analizę jakościową treści z Facebooka i narracji schronisk, w rozdziale tym zidentyfikowano trzy kluczowe praktyki: ucieleśnione modelowanie nieobecnego psa, selektywne poszukiwanie i unikanie informacji oraz tworzenie cyfrowych więzi afektywnych. W rozdziale tym wprowadzono pojęcie międzygatunkowej niesprawiedliwości świadectwa, aby opisać, w jaki sposób zwierzęta zostały epistemicznie uciszone i przedstawione wyłącznie poprzez ludzkie emocje i projekcje.This chapter investigates embodied and affective information practices that emerged during the crisis-driven dog adoptions of Poland’s ‘Frost Action 2024.’ It examines how prospective adopters formed mental and emotional representations of unfamiliar shelter dogs based on fragmentary, affect-laden information shared via social media. In this context of urgency, informed choice was displaced by relational inference and ethical immediacy. Adopters relied on symbolic captions, narrative fragments, and emotionally resonant images to build a dog in the mind and act upon projected mutual vulnerability. Using qualitative analysis of Facebook content and shelter narratives, the chapter identifies three key practices: Embodied modelling of the absent dog, selective information seeking and avoidance, and the formation of digital affective bonds. The chapter introduces the concept of interspecies testimonial injustice to describe how animals were epistemically silenced and represented solely through human affect and projection
