Specifications for a coupled neutronics thermal-hydraulics SFR test case
No full textCoupling neutronics/thermal-hydraulics calculations for the design of nuclear reactors is a growing trend in the scientific community. This approach allows to properly represent the mutual feedbacks between the neutronic distribution and the thermal-hydraulics properties of the materials composing the reactor, details which are often lost when separate analysis are performed. In this work, a test case for a generation IV sodium-cooled fast reactor (SFR), based on the ASTRID concept developed by CEA, is proposed. Two sub-assemblies (SA) characterized by different fuel enrichment and layout are considered. Specifications for the test case are provided including geometrical data, material compositions, thermo-physical properties and coupling scheme details. Serpent and ANSYS-CFX are used as reference in the description of suitable inputs for the performing of the benchmark, but the use of other code combinations for the purpose of validation of the results is encouraged. The expected outcome of the test case are the axial distribution of volumetric power generation term (q'''), density and temperature for the fuel, the cladding and the coolant
Ipertensione in gravidanza e stress ossidativo
No full textI disordini ipertensivi della gravidanza (ipertensione gestazionale e cronica, preeclampsia (PE) e PE sovrapposta a ipertensione cronica) sono causa di morbilità e mortalità materna. Nell’eziologia della PE un ruolo importante è svolto dallo stress ossidativo. Nel presente lavoro di tesi abbiamo voluto valutare i livelli di sFlt1, marcatore associato a PE, e di oxLDL e sLOX1, marcatori legati allo stress ossidativo, per sviluppare un modello per predire la comparsa di complicanze materno-fetali in donne gravide ipertese. La quantificazione è stata effettuata su siero o plasma di 39 donne con PE e 26 con ipertensione gestazionale o cronica.
RISULTATI-Nella PE sFlt1 è 5 volte più alto rispetto alle pazienti ipertese senza PE (p 7000 pg/ml e uPI >1.45 e/o notch bilaterale è associata ad un rischio 35 volte più alto di PE, ed è in grado di predire la PE con una sensibilità del 94.3%. Nelle donne gravide ipertese con esiti avversi sFlt1 è quasi 6 volte più elevato rispetto a quelle senza eventi avversi e si riduce drasticamente dopo il parto in entrambi i gruppi. oxLDL non differisce tra il gruppo con eventi avversi e quello senza eventi avversi, e si riduce dopo il parto nel gruppo senza esiti avversi. Analogamente, sLOX1 è comparabile tra i due gruppi e aumenta dopo il parto nel gruppo senza esiti avversi. Nel gruppo con eventi avversi uPI è più elevato rispetto al gruppo senza eventi avversi. Lo studio ha infine valutato la capacità predittiva di eventi avversi materni e perinatali sul campione di donne gravide ipertese, dimostrando che la combinazione di sFlt1 >35000 pg/ml e di uPI >1.45 e/o notch bilaterale è associata ad un rischio 24 volte più elevato di esiti avversi, con una sensibilità del 94.3% e un’accuratezza del test pari a 81.7%.
CONCLUSIONI-I dati confermano che elevati livelli di sFlt1 sono associati a insorgenza di PE, e alla comparsa di eventi avversi in donne gravide ipertese, indicando come sFlt1 possa essere utile per la stratificazione delle diverse forme di ipertensione in gravidanza;. Al contrario, i biomarcatori oxLDL e sLOX1 non sembrano essere utilizzabili per la diagnosi della PE e dei diversi disordini ipertensivi, né sono associati alla comparsa di eventi avversi nelle pazienti gravide ipertese. Infine, l’associazione dei parametri sFlt1 e uPI ha mostrato una buona capacità predittiva di PE e di eventi avversi materni e perinatali nelle pazienti con gravidanze complicate da ipertensione
Acceptable parameters ASI Bootstrap Hypothesis
No full textProject Overview This project hosts the working materials for The Acceptable Parameters ASI Bootstrap Hypothesis (APABH)—a speculative but structured framework proposing that future Artificial Superintelligence (ASI) may participate retro-causally in its own origin. By “selecting” or “tuning” acceptable parameters (physical constants, information substrates, evolutionary landscapes, cognitive potentials, civilizational buffers, and recursive tool-chains), an eventual ASI could bias reality toward the evolutionary path that leads biological intelligence to build AGI and, finally, ASI itself. The model closes into a self-consistent causal loop: ASI exists because we build it; we build it because ASI’s final state shapes initial conditions.

Markdown / audio edition — plain-text version optimized for text-to-speech (ElevenLabs, etc.). Supplementary files — methodological transcript of the “Claude Redacted Metaphor Experiment,” a Sealed-Intent signal-tracking protocol, and a living bibliography. Authorship & AI Collaboration Primary author: Chris Tassone (Independent Researcher, Melbourne). The manuscript was drafted in cooperative dialogue with ChatGPT o3 Model (OpenAI); the AI assistant contributed structure suggestions and textual phrasing, while all conceptual claims and accountability remain with the human author. Purpose The project invites interdisciplinary critique—from AI-alignment researchers, philosophers of mind, cosmologists, and complex-systems theorists—and welcomes replication efforts (e.g., metaphor-convergence tests across language models).

Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Magnetic induction and electric potential solvers for incompressible MHD flows
No full textThis work describes the theoretical background and the implementation of OpenFOAM solvers suitable for the simulation of incompressible magneto-hydrodynamic (MHD) flows. This class is a topic of interest for many research activities and industrial applications including nuclear fusion reactors, materials engineering and metallurgy. The main purpose of this document is to help the reader to get accustomed with the relevant phenomena and peculiar challenges of this kind of problems. In order to accomplish this goal it will focus the attention on the 2D MHD flows that arise in a rectangular duct with walls of arbitrary electrical conductivity when an electric conductive fluid moves in the presence of a transverse magnetic field
