Artificial Intelligence in Radiology: Safeguarding Patients’ Rights in the Digital Era
Full text linkArtificial intelligence (AI) is now firmly embedded in radiology practice. From automated abnormality detection on chest radiographs to workflow optimization in triage, AI is increasingly shaping diagnostic processes. Its promise is substantial: improved efficiency, faster reporting, and better diagnostic accuracy. Yet these benefits come with risks that extend beyond technical performance. For radiologists, the critical challenge is to ensure that integration of AI into clinical practice does not compromise patients’ fundamental rights. This is not only a professional duty, but also a legal obligation. Under the recently adopted EU Artificial Intelligence Act (AI Act), hospitals and clinicians deploying “high-risk” AI systems, including most radiology applications, are required to demonstrate adequate AI literacy. Radiologists must be equipped not only to understand technical aspects but also to assess risks for patients
ER: Existence, Reality and Time (Reading sample)
No full textER: Existence, Reality and Time is a philosophical book that advances the project first initiated in Time Explained. Where the earlier volume introduced the central intuitions and initial architecture of Existential Realism (ER), this work moves decisively into its conceptual core. With both analytic precision and conceptual clarity, it examines how existence unfolds strictly in the present, how reality meaningfully relates to past and future, and why becoming—rather than static being—must anchor any adequate theory of time. Addressing questions left open in its predecessor, the book refines and strengthens the framework of ER, presenting a coherent temporal model that brings lived experience and scientific understanding into systematic alignment
MIARO — Appendix A: Epistemic Disruptors, Non-Localizable Interventions, and the Causal Asymmetry Test
No full textThis appendix extends the MIARO framework by examining epistemic disruptions caused by non-localizable external interventions, such as opaque updates or causal intrusions inaccessible to the system’s internal history. It argues that such interventions function as asymmetry tests, revealing structural limits in origin inference even under ideal internal coherence. The analysis clarifies how rational agents may detect causal discontinuities without being able to localize or reconstruct their source, reinforcing the persistence of causal asymmetry. The appendix situates these results within debates on AI epistemology, interpretability, and the limits of self-referential explanation
Manifestation of the Compassion-Structure in Aesthetic Experience
Full text linkThis paper examines aesthetic experience as the experiential manifestation of evaluation persistence, a structural condition identified in the theory of evaluative bifurcation.
In ordinary judgment, detected difference generates a demand for correction that resolves through exclusion or determination.
In certain aesthetic cases, however, difference remains present without producing exclusion pressure.
Harmony is therefore described as a condition in which evaluation persists while the demand for determination does not arise.
Calmness appears as the experiential manifestation of a non-terminating evaluative structure rather than its psychological cause.
Because judgment operates where complete determination is not achieved, evaluation does not terminate through exclusion in this case.
The evaluative form constrained by this non-excludability is termed compassion, understood not as emotion or virtue but as a structural condition for the persistence of evaluation.
Beauty is therefore interpreted as the experiential manifestation of evaluation persistence
Admissible Region Theory: A Unified Mathematical Framework for Stability, Control, and Optimization
No full textAbstract
Many mathematical and engineering disciplines analyse systems by studying the behaviour of trajectories within a defined state space. However, these analyses often treat stability, control, optimization, and constraint satisfaction as separate problems. This paper proposes a unifying interpretation: each of these disciplines is fundamentally concerned with identifying and maintaining system trajectories within an admissible region of state space. The admissible region represents the subset of states compatible with governing constraints and system continuation. By formalising this concept, numerical stability, control systems, optimization procedures, signal processing constraints, and phase-space dynamics can be interpreted as different operational perspectives on the same structural object.
Description
This paper introduces the concept of an admissible region as a unifying mathematical structure underlying several disciplines including numerical stability analysis, control theory, optimization, and dynamical systems. By identifying the subset of state space in which valid system trajectories must remain, the paper demonstrates that many apparently distinct mathematical methods are different operational mechanisms for maintaining system behaviour within admissible constraints. The framework provides a structural interpretation linking stability, control, optimization, and phase-space dynamics within a single conceptual model
Le dualisme de la signification : règle, effectivité, liberté et morale
No full textLe débat contemporain entre physicalisme réductionniste et physicalisme non réductionniste repose sur une présupposition qui demeure insuffisamment interrogée : l’idée selon laquelle la question décisive serait d’abord de savoir si le mental, la conscience, le langage ou la morale sont réductibles à la matière. Cette formulation du problème s’inscrit déjà dans un schème moniste, en ce qu’elle tient pour acquis l’identité de principe entre l’être et le registre matériel. La présente étude soutient qu’un tel cadre manque le problème premier, qui n’est pas celui de la réduction du mental au physique, mais celui de l’irréductibilité de la règle, de la signification et de la forme normative à leur support matériel. Le dualisme défendu ici ne renvoie ni à un spiritualisme naïf ni à une séparation théologique entre l’âme et le corps. Il désigne la dualité constitutive entre la matière et l’idée, entre le support causal et la forme signifiante, entre l’effectuation d’une règle et sa formulation. Le présent article s’ouvre sur une critique programmatique de la confusion physicaliste entre l’information et son support matériel, puis examine la machine comme lieu d’effectuation concrète de la règle. Il montre ensuite que les énoncés totalisants de type moniste échouent à produire un contenu véritablement connaissable, avant d’élargir l’analyse à la structure duale du langage, des mathématiques et des organismes. Sur cette base, la liberté est repensée, non comme suspension miraculeuse du déterminisme, mais comme compréhension croissante des contraintes. Une telle perspective conduit à réinscrire la question de la vérité, de la connaissance et de la morale dans une philosophie de la signification où le rapport entre l’idée et le monde ne se réduit jamais à l’identité de la matière avec elle-même.

慈悲と暴力の構造：評価動力学からの存在論的再定義
No full text本稿は慈悲と暴力を倫理的対立概念としてではなく、評価構造の二つの作動様式として再定式化する。差異帰属動力学の枠組みにおいて評価は帰属候補分布の確率更新として定義される。評価更新は帰属候補の排除と保持の二つの方向を持つ。本稿は排除構造を暴力、非排除構造を慈悲として定式化する。これらは対立する原理ではなく評価構造の同時的側面であり、対象生成および推論過程に内在する。本稿はこの構造を示すことにより、慈悲と暴力を倫理心理学ではなく評価動力学の存在条件として再定義する

No full textΟ Jurgen Habermas έφυγε από τον κόσμο την Παρασκευή 14 Μαρτίου 2026 σε ηλικία 96 ετών. Υπήρξε οάξιος επίγονος της Κριτικής θεωρίας της σχολής της Φρανκφούρτης και σπουδαίος στοχαστής τηςδημοκρατικής πολιτικής και του επικοινωνιακού πράττειν ή και της δημοκρατικής πολιτικής ωςεπικοινωνιακού πράττειν. Επιπλέον, υπήρξε ένας από τους τελευταίους μεγάλους στοχαστές τηςκοινωνικο-ιστορικής γέφυρας ανάμεσα στον αναλογικό και τον ψηφιακό αιώνα και, ως κριτικόςθεωρητικός, ιδιαίτερα οξυδερκής όσον αφορά τις επιπτώσεις των ψηφιακών τεχνολογιών στη δημόσιασφαίρα, ιχνηλατώντας τους σύγχρονους κοινωνικούς μετασχηματισμούς. Παραδόξως το 2024, στα τέλη της ζωής του, υπήρξε θύμα της τεχνοκρατικής ιδεολογίας που ο ίδιος κατέκρινε, όταν η DeepMind της Google παρουσίασε ένα μοντέλο Τεχνητής Νοημοσύνης με το όνομα “Μηχανή Χάμπερμας”/ Habermas Machine
Bandlimited Green's Functions from Minkowski Isometry: A Geometric Derivation of Celestial Conformal Weights
No full textWe present a complete, parameter-free derivation of the bandlimited Green's function G = \sin (\sqrt{- \sigma^2}) and the celestial conformal weights \Delta_l = l + 1 from a single input: four-dimensional Minkowski spacetime (M,\eta_{\mu \nu}). The derivation proceeds in three steps. First, the exactness of the exponential map \exp_p: T_p M \to M in flat spacetime, combined with the requirement that discrete sampling be isometrically equivalent to the continuous field, uniquely determines—via the Whittaker interpolation theorem—the reproducing kernel G = \sin (\Omega \sqrt{- \sigma^2}). Second, the null geodesic locus \sigma^2 = 0 emerges as the natural boundary through the reproducing kernel normalisation condition K(x,x) = 1; restriction to this null hypersurface induces a signature flip from Lorentzian (- , + , + , +) to Euclidean (+, +) on the transverse S^2. Third, the SL(2,\mathbb{C}) principal-series representation on the Euclidean celestial sphere, combined with the spherical Bessel decomposition of G, yields \Delta_l = l + 1 as a pure spectral theorem with no free parameters. The result is cross-validated by five independent routes: Kempf's operator-theoretic reconstruction, the present geometric construction, a boundary RKHS derivation, Pasterski-Shao-Strominger from scattering amplitudes, and Gover-Shaukat-Waldron tractor calculus providing the SO(4,2) group-theoretic skeleton explaining why all five routes converge. The scale \Omega is structurally irrelevant: all physical conclusions depend only on the Minkowski metric. We identify the null-geodesic data set as a natural basis for geometric consistency checks, and note that if the universe is a quantum state, the multi-path convergence in principle circumvents the classical cosmic variance bound
