This article explores Albert the Great’s understanding of human cognition as a hierarchical, semiotic structure, made of light. It examines his response to the question “What is good for man?”, tracing his shift from a moral–theological to an anthropological and epistemological perspective in dialogue with Aristotelian, Neoplatonic, and Arabic sources. Through close textual analysis of his writings on the soul and intellect, the article reconstructs man’s hierarchical constitution and highlights the central role of signs and of the imagery of light and shadows in his understanding of cognition. It argues that, for Albert, each level of apprehension functions as a semiotic link that dynamically leads the human intellect from lower to higher degrees of comprehension, intentionally pointing toward the divine source of all being, understood as light. Albert’s conception of signs, intentionality, and intellectual illumination is shown to anticipate and go beyond later semiotic theories. Consequently, the article proposes that he should be regarded as a “proto-semiotic” thinker whose original anthropological synthesis, centered on epistemology and sign-theory, illuminates the intrinsic role of signs in human perfection and clarifies how words and images can express the cognitive relation between created and uncreated being.

This article examines the ontological and ethical foundations of ecosufism through the views articulated by Muḥyiddīn Ibn ʿArabī (d. 638 AH/1240 CE) and Mawlānā Jalāl al-Dīn Rūmī (d. 672 AH/1273 CE) in their major works. Its central argument is that these two foundational figures of Sufi metaphysics offer a coherent, theocentric account of the human–nature relationship grounded in the principles of waḥdat (unity) and tajallī (self-disclosure). Conceiving the cosmos as a living and conscious reality, Ibn ʿArabī and Rūmī further deepen this ontological vision through the Qurʾānic notions of khilāfah (vicegerency) and amānah (trust). These concepts are explained in Ibn ʿArabī’s teaching of al-insān al-kāmil (the Perfect Man) and in Rūmī’s teachings on humility and mercy, as both an ontological and ethical responsibility. This responsibility is expressed through the practical and ethical virtue of iʿtidāl (moderation), which limits the use of natural resources by humans. In this sense, ecosufism stands in clear opposition to anthropocentric approaches, rejecting the reduction of nature to a mere means to human ends. The study also shows that, without claiming any historical origin or conceptual identity, there are notable parallels between the foundations of ecosufism and modern ecological approaches. In this respect, meaningful points of convergence can be identified between ecosufism’s ontological and ethical framework and contemporary perspectives such as deep ecology, the intrinsic value of nature, the idea of a living cosmos, panpsychism, environmental stewardship, and environmental virtue ethics. The article argues that ecosufism, as an understanding that explains human–nature relationships both in a metaphysical sense and how this relationship should be reflected in concrete practices, has the potential to contribute to today’s ecological problems at both the theoretical and practical levels.

Genetic variation in PNPLA3 influences liver fat accumulation and hepatocellular injury in various liver diseases. However, the role of PNPLA3 intronic polymorphisms in hepatic damage among hepatitis C virus (HCV) patients remains unclear. This study aims to investigate the association of three intronic PNPLA3 polymorphisms (rs4823173, rs2896019, and rs2281135) with liver injury in HCV-infected patients with spontaneous HCV clearance (SC) and chronic hepatitis C (CHC). A total of 218 HCV-positive individuals were classified into SC (n = 64) or CHC (n = 154) groups. PNPLA3 genotypes were determined by qPCR using TaqMan probes and liver damage through serum markers, noninvasive index, and liver stiffness. Among SC patients, the genotypes AA-rs4823173, GG-rs2896019, and AA-rs2281135 were associated with higher AST, ALT, and APRI, as well as decreased platelet counts, compared with patients homozygous for the non-risk genotypes (p < 0.05). No associations were found in CHC patients. The three polymorphisms were in perfect linkage disequilibrium (r² = 1). The risk haplotype AGA was associated with higher AST and ALT, as well as lower platelet counts (p < 0.05) in SC patients. PNPLA3 intronic polymorphisms and their association with serum liver injury markers could help identify hepatic injury in HCV-negative patients. Full article

The maritime transportation industry is under pressure to reduce the level of emissions generated annually by commercial vessels. In order to achieve this objective, regulatory bodies, both national and international, have imposed strict limitations on the industry, and thus major changes have to be made in a tight time frame. In the last decade, engineers and ship designers have been searching for alternatives to traditional fuels, but it is not easy to find a perfect balance between operational costs and economic efficiency. Many potential solutions are being studied, with some of them already proven and implemented, such as liquefied natural gas, solar and wind power, electric propulsion, and many more. One solution might be biofuels, and this study aims to assess the potential impact of their use on the energy performance and durability of a typical marine propulsion engine, namely the MAN B&W 6S70MC-C7, fitted on board many types of ships including large oil tankers, container ships and bulk carriers. The main topic is approached through a progressive structure, starting from the analysis of general characteristics of these fuels and the engine installation, comparative simulations, operational experience, and technical recommendations. The comparative assessment is focused on two traditional types of fuels and two biofuel types. The aim is to identify a viable solution that can sustain the operational efficiency of this main engine without a major impact on its maintenance cycle and without additional costs on the components. Even if these biofuels are more expensive than the traditional ones, in the long run, they could prove to be a better choice in terms of operational costs and compliance with regulation.

Internet of Things deployments face escalating security threats, yet systematic methods for auditing the defensive posture of IoT device networks remain underdeveloped. Current intrusion detection evaluations focus on algorithmic accuracy while neglecting operational requirements—computational efficiency, reproducibility, and interpretable risk assessment—that security audits demand. This paper introduces a reproducible security audit framework for IoT device networks, demonstrated through systematic evaluation of four machine learning models (Random Forest, LightGBM, XGBoost, Logistic Regression) on the TON_IoT dataset containing nine attack categories targeting smart environments. Our audit methodology enforces strict feature hygiene by excluding identity-revealing attributes, benchmarks both threat detection capability and computational cost, and provides complete reproducibility artifacts including preprocessing pipelines and trained models. The framework evaluates security posture through dual lenses: binary classification (distinguishing compromised from legitimate traffic) and multiclass classification (attributing threats to specific attack types). Binary audit results show ensemble models achieve 99.8–99.9% accuracy with perfect ROC-AUC (100%) and sub-15 ms inference latency per 1000 flows, confirming reliable attack detection. Multiclass auditing reveals more nuanced findings: while overall accuracy reaches 99.0% with macro-F1 near 97%, rare attack types expose critical blind spots—man-in-the-middle threats achieve only 78% F1 despite representing serious security risks. LightGBM provides optimal audit performance, balancing 99.93% detection accuracy with 2.76 MB deployment footprint. We translate audit findings into actionable security recommendations (network segmentation, rate-limiting, TLS metadata collection) and compare against twenty published studies, demonstrating that our framework achieves competitive detection rates while uniquely delivering the transparency, efficiency metrics, and reproducibility required for credible security assessment of production IoT networks.

Aristotle’s theory of soul was a hot topic in the Late Middle Ages and it sparked a great series of debates with serious theological and philosophical implications. The medieval commentators of Aristotle played a crucial role in the dissemination of these debates since their explanations and commentaries on Aristotle’s theory of soul served as a springboard for further discussions. One of the most important medieval commentators of Aristotle was Albert the Great (ca 1200–1280) who dealt extensively with the topic of soul and its connection with the doctrine of intellect. Albert discussed the subject of soul not only in the Aristotelian commentaries but also in many genuine works of his which delineated Albert’s theory of soul in great detail. This paper will primarily focus on two works of Albert, De homine and Liber de natura et origine animae; it aims to provide a coherent account of Albert’s early theory of soul and to shed some light on important hermeneutical issues that derive from these two works.

Agape, philia, and eros are the forms of love that receive most attention in the work of the French philosopher Paul Ricœur. The general consensus among commentators is that when Ricœur talks about agape, he means a love that is all about giving, with no expectation of receiving anything in return; and when he talks about eros, he means something close to erotic love or erotic desire. This article builds on the research of two French commentators, Olivier Abel and Jérôme Porée, to offer a more detailed account of what Ricœur says about love of neighbour and concern for others, and where he says it, during one very specific period: 1947–1960. That is the period when Ricœur was very committed to education reform in France. However, the article disputes Abel and Porée’s interpretation of what Ricœur means by eros in Fallible Man, a work of philosophical anthropology published in 1960. The article shows that Ricœur’s interpretation of eros, far from being the standard one, is in fact highly original, and a perfect example of the imaginative use of philosophical resources that marked his early career. The article also discusses The Symbolism of Evil, a second work of philosophical anthropology that Ricœur published the very same year. In the context of that discussion, it draws attention to two references to “love” that link back to the eros of Fallible Man. It then offers a close reading of Marguerite Léna’s insightful commentary on a remarkable passage from The Symbolism of Evil, where Ricœur talks about the essential roles that love and fear play in all forms of education, including moral education.

A conventional PCR (cPCR) remains an effective molecular technique for the diagnosis of canine monocytic ehrlichiosis. However, agarose gel electrophoresis requires additional time after thermal cycling. In the present study, we developed a PCR-based lateral flow biosensor (PCR-LFB) to detect Ehrlichia canis (E. canis). Lateral flow strips allow for the simple and rapid detection of PCR products and provide an alternative to gel electrophoresis. The sensitivity, specificity, and detection limit of PCR-LFB were compared to those of TaqMan probe-based real-time PCRs (qPCRs). The PCR-LFB was performed with 5′ 6-FITC and biotin-labeled primers specific to E. canis, targeting the dsb gene. The detection limit of the PCR-LFB assay was 10⁻⁶ for the target DNA sequence in a 10-fold dilution of the recombinant plasmid, which is 10 times lower than that of qPCR. Among the confirmed qPCR results in the 30 dog samples, false-positive results were not detected by the PCR-LFB. Compared to qPCR, the sensitivity and specificity of PCR-LFB were 63.6% (95% CI; 42.9–80.2%) and 100% (95% CI; 67.5–100%), respectively. The Kappa value of the PCR-LFB is in moderate agreement with the qPCR (κ = 0.483). Perfect agreement (κ = 1) was observed between cPCR and PCR-LFB. Lower cost and shorter time consumption were demonstrated using PCR-LFB. Full article

One of the main cultural achievements of modernity, according to Hartmut Rosa, is that it has nearly perfected “human beings’ ability to establish a certain distance from the world while at the same time bringing it within our manipulative reach”. Although this ‘achievement’ has ensured many remarkable scientific and technological developments, the consequences for culture have been more negative, often taking the form of what is often referred to as the malaise of modernity. Over time, this malaise has intensified to make way for what is now commonly known as the crisis of meaning, which pivots around the erosion of three orders of meaning, named and discussed by John Vervaeke: the nomological order, the narrative order, and the normative order. The work of G. K. Chesterton is consulted, in this article, to grapple with the deeper theological meaning of the modern malaise and the present crisis of meaning. In Chesterton’s work, it is better to interpret any cultural crisis, like the Edwardian cultural crisis he saw first-hand, as well as the current meaning crisis, through theology, and especially in relation to the doctrines of God’s goodness, the goodness of created order, and the doctrine of original sin, narrated as the fall of man. Through this, it becomes possible to better understand and articulate Chesterton’s theological mediation of culture as a more specific aspect of his larger hermeneutical awareness. Full article

The following article aims at highlighting the theurgical tendencies in the teachings of the great Andalusī Muslim mystic Muḥyī l-Dīn Ibn al-ʿArabī (560/1165–638/1240). By “theurgy” is meant the influence of man on Divinity in its manifest external dimension, that is to say, the dimension of God that creates beings and is involved with their lives and fortunes, as opposed to His hidden essence. The category “theurgy/theurgical” is adopted from the modern academic study of Kabbalah, and is ultimately derived from Late Antique Neoplatonism. The bulk of this article is dedicated to analyzing relevant texts from Ibn al-ʿArabī’s oeuvre and elucidating the theurgical elements reflected in them, while the last two sections (5–6) present preliminary observations on the relevant links between Ibn al-ʿArabī, Kabbalah, and Late Antique Neoplatonism. It is argued that these three traditions should be studied together, as they shed light on one another. Full article

This article explores the metaphor of death in Qing 清 Dynasty Daoist inner alchemy (neidan 內丹) scriptures, which require practitioners to consider themselves dead or living dead, and argues that this metaphor of death can be traced back to the connotation of the “living dead” proposed by the founder of Complete Perfection (Quanzhen 全真), Wang Chongyang 王重陽, in the Jin 金 Dynasty, who demonstrated his desire for the return of Dao by digging a grave for himself and referring to himself as a living dead man. In addition, this paper also analyzes the psychological connotations represented by the living dead, pointing out that it contains a profound theme of death and rebirth. Full article

With the rise of the Internet of Things (IoT), maintaining data confidentiality and protecting user privacy have become increasingly challenging. End devices in the IoT are often deployed in unattended environments and connected to open networks, making them vulnerable to physical tampering and other security attacks. Different authentication key agreement (AKA) schemes have been used in practice; several of them do not cover the necessary security features or are incompatible with resource-constrained end devices. Their security proofs have been performed under the Random-Oracle model. We present an AKA protocol for end devices and servers. The proposal leverages the ECC-based key exchange mechanism and one-way hash function-based message authentication method to achieve mutual authentication, user anonymity, and forward security. A formal security proof of the proposed scheme is performed under the standard model and the eCK model with the elliptic curve encryption computational assumptions, and formal verification is performed with ProVerif. According to the performance comparison, it is revealed that the proposed scheme offers user anonymity, perfect forward security, and mutual authentication, and resists typical attacks such as ephemeral secret leakage attacks, impersonation attacks, man-in-the-middle attacks, and key compromise impersonation attacks. Moreover, the proposed scheme has the lowest computational and communication overhead compared to existing schemes. Full article

This essay argues that the long-standing assumption that Chan Buddhism began as a meditation movement is outdated and needs to be replaced by a paradigm that sees the origins of Chan in a set of literary inventions that took form in the mid-Tang era and were designed to prove that the totality of tradition was owned by certain masters of the day. These bold claims to own perfect tradition were bolstered by newly invented genealogies that worked to show that this or that master was, in effect, a descendant of the Indian Buddha, and, thus, a quasi-Buddha himself. Further finessing these efforts to take over final authority in the world of Tang Buddhism was the studied use of Daoist tropes to naturalize and soften these aggressive claims, all in order to make them more appealing to elite readers who could now be impressed by decidedly Chinese-looking portrayals of perfect Buddhism, set on the timeless ground of the Great Dao, where there could be no competition, envy, literary pretensions, or even Buddhist practices—just pure and total truth in the body of a Chinese man. In trying to make sense of this cycle of carefully rewriting the past in order to control the present (and future), it should be clear that we need to switch to a paradigm that accepts that the seductive reinvention of tradition was done consciously and with no small amount of craft and cunning.

In this work, we compare the basketball scoring performance of two imaginary (simulated) mechanical robots in conditions of erroneous information-processing circuits: Machine, whose moves are controlled by a conventional digital computer and Man, controlled by a random pulse computer composed of biologically-inspired circuits which execute basic arithmetic operations. This is the first comparative study of robustness of the digital and the random pulse computing paradigms, with respect to the error rate of the information-processing circuits ($p_{err}$), for a mechanical robot. In spite of the fact that Man’s computer consists of only about 100 logic gates while Machine’s requires about 3500 gates, Man achieves a significantly higher scoring probability for $p_{err}$ in the range from 0.01% all the way to 10%, while at lower $p_{err}$, both converge to the perfect score. Furthermore, Man’s hits make up a smooth Gaussian distribution with a vanishing probability of making large misses even at the highest $p_{err}$, while Machine is prone to spectacular misses already at $p_{err}$ as low as 1 part-per-million. These findings indicate that the biologically inspired computation requires less hardware for the same task, and ensures higher robustness and better behaving operation than digital computation, which are characteristics of importance for the survivability of living beings.

Geoheritage sites are important resources due to the diverse ways in which they can be utilized. There are small, low-ranked geosites that have attracted significant attention from the lay public. This study reports on one such geosite from the Hosta area of the Western Caucasus. Field observations allowed us to make judgments related to its geoheritage properties and establish the factors for its successful touristic exploitation. This geosite represents a furrow in the Upper Cretaceous limestones in the area, which inherited the former weak zone or minor fault and grew due to landslides. The degree of uniqueness of this geosite is low; it is curvilinear in space; it boasts perfect accessibility, including from a nearby resort, and its landscape context is scenic. The Labyrinth geosite is located in a yew–boxwood grove in the natural reserve, and it is visited by crowds of tourists. Three direct factors in its exploitation success are proposed as follows: story (popular explanation of the geosite’s origin), route (inclusion into a popular touristic route through the grove), and cultural appeal (analogy to man-made labyrinths). Applying these factors to another geoheritage-rich area of the Western Caucasus implied that some of them may not be meaningful according to objective reasons, but that there are other important factors such as geoproduct (particularly geofood) selling. It is also noted that the small size and relatively low value of geosites do not necessarily limit their geotouristic potential. Overall, this case study suggests that “selling” geosites successfully requires advanced, innovative solutions and significant creativity. Full article
