Vibration sensors are important in many engineering fields, including industry, surgery, space, and mechanics, such as for remote and autonomous driving. We propose a novel, cutting-edge vibratory sensor that mimics human tactile receptors, with a configuration different from current sensors such as strain gauges and piezo materials. The basic principle involves the perception of vibration via touch, with a cutaneous mechanoreceptor that is sensitive to vibration. We investigated the characteristics of the proposed vibratory sensor, in which the mechanoreceptor was covered either in hard rubber (such as silicon oil) or soft rubber (such as urethane), for both low- and high-frequency ranges. The fabricated sensor is based on piezoelectricity with a built-in voltage. It senses applied vibration by means of hairs in the sensor and the hardness of the outer cover. We also investigated two proposed parameters: the sensor response time to stimuli to the vibration aiding the equivalent firing rate (e.f.r.) and the gauge factor (GF_,pe) proposed as treated in piezo-resistivity. The evaluation with the parameters was effective in designing a sensor based on piezoelectricity. These parameters were enhanced by the hairs in the sensor and the hardness of the outer cover. Our results were helpful for designing the present novel vibratory sensor. Full article

The application of organic amendments in agriculture has gained increasing attention as a sustainable approach to improving soil fertility and crop productivity. This study assessed the effects of vermicompost derived from water buffalo (Bubalus bubalis) manure on the yield and biochemical quality of cauliflower cultivated in soil types typical of the Campania region: loam and clay. Three fertilization treatments were tested, an unfertilized control, vermicompost (140 kg N ha⁻¹), and mineral fertilizer (MIN), at the same nitrogen rate. The results showed that vermicompost more significantly improved plant growth compared to the unfertilized control, particularly in loam soil, where the biomass and the leaf number increased by 160% and 335%, respectively. In clay soil, vermicompost enhanced nutrient availability, leading to a 159% biomass increase relative to the control. While mineral fertilization resulted in the highest yields, vermicompost improved the antioxidant capacity and influenced the amino acid composition, particularly in clay soil, where it enhanced the total amino acid content by 35% over that of the control. Additionally, vermicompost increased the quantity of soil organic matter and moderated the oxidative stress responses, suggesting long-term benefits for soil health. These findings highlight the potential of vermicompost as an effective and sustainable soil amendment, particularly in regions with intensive livestock farming and nitrate-sensitive environments. Further research is needed to optimize its integration with conventional fertilization strategies to maximize the agronomic and environmental benefits. Full article

The Mysteries of Udolpho was published at a time when poetry and music were being redefined, along with the notions of imitation and expression. From a precedence of word over music, theorists, musicians and composers started reconsidering the hierarchy of arts, which led to a new appreciation of both sung music and instrumental music. Ann Radcliffe’s novel is replete with pleasing sounds and mysterious melodies, working both as part of her décor and general soundscape and as a key element of the narrative. Given the novel’s musical profusion and versatility, one may wonder how to adapt its musicality into actual music. This paper, therefore, endeavors to define the balance of imitation and expression in The Mysteries of Udolpho and questions the ability of other media, especially those relying on sounds, to adapt its musical richness. It first focuses on the novel’s inscription in the larger context of musical theory, before delving into the limits of language’s sound mimesis and its counteracting expressivity. The final part is a case study of three artworks inspired by Radcliffe’s novel: John Bray’s song “Soft as yon’s silver ray that sleeps”, Catherine Czerkawska’s radio dramatization The Mysteries of Udolpho, and Marc Morvan and Benjamin Jarry’s album Udolpho.

The transnational turn in migrant studies emphasizes complexities in migration, partly related to the agency that migrants may exercise. Chapter 44 in the biblical Book of Jeremiah holds a story of migration that is peculiarly insensitive to such aspects: religious practices performed by a local community are condemned, and so are they. Through a series of analytical steps—reflection on historical conditions of migration at the time, on the historical value of the biblical sources, on a cognitive theory of mimesis in narrative, and on praxeological analysis—this study tries to regain a view of migratory complexity and migrants’ agency in that story. The reading uncovers how migrants were “doing community” through their religious practices and through their dispute with the prophet. The story reflects an enduring pattern of struggle between local communities and trans-local forces. It also reflects change in traditional communal patterns due to social changes brought about by migration. Full article

Prosociality is essential in human interactions, characterized by voluntary behaviors aimed at benefiting others. Promoting such behaviors is indispensable for human relationships. Studies have demonstrated positive effects of interpersonal synchrony interventions through musical sessions. Some authors suggest that the joint creation of music facilitates prosocial behaviors (PB). This review aims to determine whether evidence supports the idea that participation in a musical interpersonal synchrony experience improves PB. A systematic review of 12 selected articles was conducted. The search was carried out in databases such as WoS, Scopus, PubMed, Dialnet, Elsevier, and Eric. Results indicate that music, as a tool, creates an optimal environment for mimesis and group participation, which can enhance prosociality. Controlling variables such as sample size, population type, measurement instruments, techniques, and session design is necessary for future research. It is concluded that interpersonal synchrony through music appears to improve prosociality, although more robust studies are required. Full article

The mimesis of biological mechanisms by artificial devices constitutes the modern, rapidly expanding, multidisciplinary biomimetics sector. In the broader bioinspiration perspective, however, bioarchitectures may perform independent functions without necessarily mimicking their biological generators. In this paper, we explore such Bioarchitectonic notions and demonstrate three-dimensional photonics by the exact replication of insect organs using ultra-porous silica aerogels. The subsequent conformal systolic transformation yields their miniaturized affine ‘clones’ having higher mass density and refractive index. Focusing on the paradigms of ommatidia, the compound eye of the hornet Vespa crabro flavofasciata and the microtrichia of the scarab Protaetia cuprea phoebe, we fabricate their aerogel replicas and derivative clones and investigate their photonic functionalities. Ultralight aerogel microlens arrays are proven to be functional photonic devices having a focal length f ~ 1000 μm and f-number f/30 in the visible spectrum. Stepwise systolic transformation yields denser and affine functional elements, ultimately fused silica clones, exhibiting strong focusing properties due to their very short focal length of f ~ 35 μm and f/3.5. The fabricated transparent aerogel and xerogel replicas of microtrichia demonstrate a remarkable optical waveguiding performance, delivering light to their sub-100 nm nanotips. Dense fused silica conical clones deliver light through sub-50 nm nanotips, enabling nanoscale light–matter interactions. Super-resolution bioarchitectonics offers new and alternative tools and promises novel developments and applications in nanophotonics and other nanotechnology sectors. Full article

The advancement of Artificial Intelligence (AI) poses challenges in the field of bioethics, especially concerning issues related to life and death. AI has permeated areas such as health and research, generating ethical dilemmas and questions about privacy, decision-making, and access to technology. Life and death have been recurring human concerns, particularly in connection with depression. AI has created systems like Thanabots or Deadbots, which digitally recreate deceased individuals and allow interactions with them. These systems rely on information generated by AI users during their lifetime, raising ethical and emotional questions about the authenticity and purpose of these recreations. AI acts as a mediator between life, death, and the human being, enabling a new form of communication with the deceased. However, this raises ethical issues such as informed consent from users and the limits of digital recreation. Companies offer services like the Digital Resurrection of deceased individuals and the generation of hyper-realistic avatars. Still, concerns arise about the authenticity of these representations and their long-term emotional impact. Interaction with Thanabots may alter perceptions of death and finitude, leading to a potential “postmortal society” where death is no longer viewed as a definitive end. Nevertheless, this raises questions about the value of life and the authenticity of human experiences. AI becomes a bridge between the living and the dead, partially replacing rituals and mystical beliefs. As technology advances, there will be a need for greater transparency in interacting with AI systems and ethical reflections on the role of these technologies in shaping perceptions of life and death. Ultimately, the question arises of whether we should allow the dead to rest in peace and how to balance the pursuit of emotional relief with authenticity and respect for the memory of the deceased. A deeper ethical consideration is needed on how AI alters traditional notions of life, death, and communication in contemporary society. In this research, an interdisciplinary approach was utilized to conduct a comprehensive systematic review of the recent academic literature, followed by a detailed analysis of two key texts. Central ideas were extracted, and recurring themes were identified. Finally, a reflective analysis of the findings was conducted, yielding significant conclusions and recommendations for future research. Full article

In keeping with the title we have chosen for this follow-up volume to the Special Issue “Ethics and Literary Practice I”, we frame our introduction and summary of the essays collected here with a brief archaeology of modern literary realism at its conjoined genesis in classical Greece and the ancient Near East; such contextualization serves as a prescient backdrop for the varied focus, across a compilation of thirteen articles, on refugees and their representation [...] Full article

If the appearance of digital images does not coincide with what they look like when they are presented as authentic photos or videos, we must reflect on concepts such as mimesis, truth, Artificial Intelligence and impersonation, something that is currently gaining prominence in the education of teachers and university professors. The current study presents the results of a research focused on the scope and knowledge of the so-called ‘deepfake images’ by the university student body of the Visual and Plastic Education subject, in the Graduate Certificate in Primary Education, and the student body of the Activity Design subject, in the master’s degree in Secondary Education—Specialty in Drawing, in the subject of Activity Design, University of Zaragoza. To do so, a quasi-experimental design with qualitative methodology was used, in which of 100 students participated. As a data collection strategy, reports were used, based on semi-structured questions, for the analysis of the development of critical thinking. The achieved results allow us to verify that deepfakes put forward an innovation in the study by university classrooms. The use of these deepfake representations is a novel issue that generates some moral and ethical controversy due to the different uses it can have, where the age of the interpreter is a differentiating factor for the knowledge and the possibilities that these imaginaries present. Therefore, it is a work area belonging to the field of artistic education on which little exploration and research has been conducted. Based on the obtained results, we conclude that there is currently a better awareness on the part of artistic education, and of education itself, in general terms, regarding the knowledge by the students, the relevance of its use, and the possibilities of these technological tools, both in their creative aspect and their misinformative ones.

Several scholars have observed the constructive possibilities in approaching sport as cultural liturgy. In what follows, I turn to hermeneutic resources in Paul Ricoeur and Augustine to elucidate the means of sports’ liturgical appropriation and the capacity of this appropriation to mediate values of ideological and religious significance. Drawing on Ricoeur’s analysis of Aristotelian mimesis, I approach sport as embodied metaphor and so locate metaphor as a central problem in sport hermeneutics. Following Ricoeur, I address this problem primarily by way of the ‘surplus of meaning’ within metaphor and its reference, and the role of Wittgensteinian ‘seeing-as’ in metaphor’s interpretation. Following Augustine, I observe the pivotal roles of desire and tradition within ‘ways of seeing’ and their outworkings in Augustine’s liturgical interpretation of ancient spectacles. Translating these considerations into sport, I argue that sport’s liturgical appropriation similarly proceeds through ‘ways of seeing’ or experiencing the embodied metaphor of sport, and that these ways are deeply informed by particular desires and cultural and ideological traditions.

Cerium oxide nanoparticles (CNPs) are biocompatible nanozymes exerting multifunctional biomimetic activities, including superoxide dismutase (SOD), catalase, glutathione peroxidase, photolyase, and phosphatase. SOD- and catalase-mimesis depend on Ce³⁺/Ce⁴⁺ redox switch on nanoparticle surface, which allows scavenging the most noxious reactive oxygen species in a self-regenerating, energy-free manner. As oxidative stress plays pivotal roles in the pathogenesis of inflammatory disorders, CNPs have recently attracted attention as potential anti-inflammatory agents. A careful survey of the literature reveals that CNPs, alone or as constituents of implants and scaffolds, strongly contrast chronic inflammation (including neurodegenerative and autoimmune diseases, liver steatosis, gastrointestinal disorders), infections, and trauma, thereby ameliorating/restoring organ function. By general consensus, CNPs inhibit inflammation cues while boosting the pro-resolving anti-inflammatory signaling pathways. The mechanism of CNPs’ anti-inflammatory effects has hardly been investigated, being rather deductively attributed to CNP-induced ROS scavenging. However, CNPs are multi-functional nanozymes that exert additional bioactivities independent from the Ce³⁺/Ce⁴⁺ redox switch, such as phosphatase activity, which could conceivably mediate some of the anti-inflammatory effects reported, suggesting that CNPs fight inflammation via pleiotropic actions. Since CNP anti-inflammatory activity is potentially a pharmacological breakthrough, it is important to precisely attribute the described effects to one or another of their nanozyme functions, thus achieving therapeutic credibility.

The concept of narrative holds a pivotal position in the Qurʾān, yet it has been subject to inadequate scrutiny and insufficient representation in pedagogical discourse concerning Islamic education. The present work endeavours to rectify this gap in knowledge by employing the technique of constructivist grounded theory to the Qurʾān and major exegeses, with a particular focus on the term qaṣaṣ, which pertains to the notion of narrative. This article delves into the profound tracts and maqāṣid (objectives) that qaṣaṣ hold in the Qurʾān and contemplates their exhortation for education on Islam and modern pedagogy. The analysis reveals that the qaṣaṣ present in the Qurʾān serves as a fundamental framework that directs the essence of the narrative pedagogy model of teaching and learning between the pedagogue and learner. Through typological figuration, the listener’s contemplation leads to a re-evaluation of conventional notions surrounding the dynamics between teacher and student and the dissemination of narrative within a pedagogical setting. The triad of truth, beauty and explication are fundamental pillars within this Islamic framework for narrative pedagogy, representing the essence of the human condition concerning education. Because these domains emerge from the concept of qaṣaṣ, the integration of the framework into Islamic education is a matter of utmost importance, given its centrality in the Qurʾān to foster and perfect the principles of Muslims and their sense of self.

The prospect of developing soluble and bioavailable Ti(IV) complex forms with physiological substrates, capable of influencing (patho)physiological aberrations, emerges as a challenge in the case of metabolism-related pathologies (e.g., diabetes mellitus 1 and 2). To that end, pH-specific synthetic efforts on binary Ti(IV)-(α-hydroxycarboxylic acid) systems, involving natural physiological chelator ligands (α-hydroxy isobutyric acid, D-quinic acid, 2-ethyl-2-hydroxybutyric acid) in aqueous media, led to the successful isolation of binary crystalline Ti(IV)-containing products. The new materials were physicochemically characterized by elemental analysis, FT-IR, TGA, and X-ray crystallography, revealing in all cases the presence of mononuclear Ti(IV) complexes bearing a TiO₆ core, with three bound ligands of variable deprotonation state. Solution studies through electrospray ionization mass spectrometry (ESI-MS) revealed the nature of species arising upon dissolution of the title compounds in water, thereby formulating a solid-state–solution correlation profile necessary for further employment in biological experiments. The ensuing cytotoxicity profile (pre-adipocytes and osteoblasts) of the new materials supported their use in cell differentiation experiments, thereby unraveling their structure-specific favorable effect toward adipogenesis and mineralization through an arsenal of in vitro biological assays. Collectively, well-defined atoxic binary Ti(IV)-hydroxycaboxylato complexes, bearing bound physiological substrates, emerge as competent inducers of cell differentiation, intimately associated with cell maturation, thereby (a) associating the adipogenic (insulin mimetic properties) and osteogenic potential (mineralization) of titanium and (b) justifying further investigation into the development of a new class of multipotent titanodrugs.

This essay provides an introduction to the question of the contribution of the ancient sophists to aesthetics in Western art. It commences by examining the persistent analogies to visual arts in negative and positive discussions of sophistry, both philosophical and rhetorical, and proceeds to examine sophistic rhetoric in Gorgias, Aristides, Lucian, Philostratus and Byzantine ekphrasis, culminating with Philostratus’ discussions of mimesis and phantasia in Apollonius of Tyana. The discussions of the relation of being and nonbeing in Gorgias’ On Nonbeing and in Plato’s Sophist form the ontological core of sophistic claims about imaginative invention and the sophistic advancement of voluntary illusion (apatē) as a means to poetic “justice” or “truth”. Such claims should be considered in the light of the epistemological and ontological skepticism propounded by Gorgias. Although the opprobrium attached to sophistry obscures its later influence, we can nevertheless discern a sophistic aesthetic tradition focused on the reflective reception of artworks that re-emerges in the Renaissance. In the last section, I adumbrate the lines of study for examining a sophistic Renaissance in the visual arts, with attention to antiquarianism as an area where the significance of the beholder’s imaginative projection suggests the endurance—or revitalization—of sophistic aesthetics.

Research into biomimetics has focused on science and technology, often developing the innovative parts of buildings from nature, leading to a new field of bioinspired architecture. The work of Frank Lloyd Wright is presented as an early example of bioinspired architecture and explores how buildings might be more broadly integrated into their site and environment. Integrating architecture, biomimetics and eco-mimesis as a framework to look at the work of Frank Lloyd Wright, provides a new understanding of his architecture and directions for future research into the ecological design of buildings and cities.
