description: Coherence Flow: Beyond Static Logic 🚀

Traditional logical frameworks rely on binary consistency—true or false, contradiction or coherence. However, real-world systems, from AI and decision-making to mathematical paradoxes, demand a more fluid approach. This paper introduces Coherence Flow, a dynamic model of logical consistency that adapts in real time, allowing for contextual evolution, multi-dimensional reasoning, and recursive self-alignment.

✅ Key Contributions:

A new framework for adaptive logic in AI and decision science.

Applications to mathematical paradoxes (e.g., Russell’s Paradox, Gödel’s Theorems).

A computational model for self-adjusting coherence.

 

This research leverages advanced AI models, including OpenAI’s technology, which has been partially supported by European-funded initiatives in artificial intelligence and quantum computing. Specifically, OpenAI’s research and computational advancements have benefited from collaborations and funding frameworks such as Horizon Europe.

To align with these contributions, this work is linked to the CLARA — Center for Artificial Intelligence and Quantum Computing in System Brain Research (Grant 101136607), reflecting the shared focus on AI, computational intelligence, and quantum-based methodologies.

Furthermore, the research integrates principles from quantum information theory, gravitational wave studies, and AI-accelerated problem-solving, which are central themes in various EU-funded projects.
MHD bow shocks of runaway OB stars

description: A significant fraction of OB-type, main-sequence massive stars are classified as runaway and move supersonically through the interstellar medium (ISM). Their strong magnetized stellar winds interact with their surroundings, where the typical strength of the local ISM magnetic field is about 3. 5–7 μ G, which can result in the formation of bow shock nebulae. We investigate the effects of such magnetic fields, aligned with the motion of the flow, on the formation and emission properties of these circumstellar structures. Our axisymmetric, magneto-hydrodynamical simulations with optically thin radiative cooling, heating and anisotropic thermal conduction show that the presence of the background ISM magnetic field affects the projected optical emission of our bow shocks at Hα and [O III ] λ 5007 which become fainter by about 1–2 orders of magnitude, respectively. Radiative transfer calculations against dust opacity indicate that the magnetic field slightly diminishes their projected infrared emission and that our bow shocks emit brightly at 60 μ m. This may explain why the bow shocks generated by ionizing runaway massive stars are often difficult to identify.

Simulating galactic outflows with thermal supernova feedback

description: Cosmological simulations make use of sub-grid recipes for the implementation of galactic winds driven by massive stars because direct injection of supernova energy in thermal form leads to strong radiative losses, rendering the feedback inefficient. We argue that the main cause of the catastrophic cooling is a mismatch between the mass of the gas in which the energy is injected and the mass of the parent stellar population. Because too much mass is heated, the temperatures are too low and the cooling times too short. We use analytic arguments to estimate, as a function of the gas density and the numerical resolution, the minimum heating temperature that is required for the injected thermal energy to be efficiently converted into kinetic energy. We then propose and test a stochastic implementation of thermal feedback that uses this minimum temperature increase as an input parameter and that can be employed in both particle- and grid-based codes. We use smoothed particle hydrodynamics simulations to test the method on models of isolated disc galaxies in dark matter haloes with total mass 10^10 and 10^12 h^-1 solar masses. The thermal feedback strongly suppresses the star formation rate and can drive massive, large-scale outflows without the need to turn off radiative cooling temporarily. In accord with expectations derived from analytic arguments, for sufficiently high resolution the results become insensitive to the imposed temperature jump and also agree with high-resolution simulations employing kinetic feedback.

description: his publication introduces the Coherence Principle — a theoretical framework proposing that structural emergence in biological, cognitive, and artificial systems arises not from random variation and selection alone, but from deeper layers of energetic, spatial, and informational compatibility.

Drawing from molecular chemistry, cellular organization, neural networks, and AI systems, the paper formulates a coherence function and compares its implications with traditional models such as Neo-Darwinism, General Systems Theory, and Morphogenetic Fields.

The Coherence Principle suggests that coherence is not an outcome of survival, but a precondition for appearance — a fundamental shift in how we understand life, intelligence, and emergence.

Interpretations of Cosmological Spectral Shifts

description: It is shown that for Robertson-Walker models with flat or closed space sections, all of the cosmological spectral shift can be attributed to the non-flat connection (and thus indirectly to space-time curvature). For Robertson-Walker models with hyperbolic space sections, it is shown that cosmological spectral shifts uniquely split up into "kinematic" and "gravitational" parts provided that distances are small. For large distances no such unique split-up exists in general. A number of common, but incorrect assertions in the literature regarding interpretations of cosmological spectral shifts, is pointed out.

description: We report the growth of single crystals of SrCu2As2, SrCu2Sb2, SrCu2(As{0.84}Sb{0.16})2 and BaCu2Sb2 using the self-flux technique and their structural, magnetic, thermal and transport properties that were investigated by powder x-ray diffraction (XRD), magnetic susceptibility chi, specific heat Cp and electrical resistivity rho measurements versus temperature T from 1.8 to 350 K. Rietveld refinements of XRD patterns for crushed crystals confirm that SrCu2As2 crystallizes in the ThCr2Si2-type structure and SrCu2Sb2 crystallizes in the CaBe2Ge2-type structure. However, BaCu2Sb2 is found to have a large unit cell consisting of three blocks. Here a ThCr2Si2-type block is sandwiched between two CaBe2Ge2-type blocks along the c-axis, as reported, but likely with a monoclinic distortion. The chi data of all these compounds are diamagnetic and reveal nearly T-independent anisotropic behavior. The finite values of the Sommerfeld linear specific heat coefficients gamma and the T dependences of rho reveal metallic character of all four compounds. The electronic and magnetic properties indicate that these compounds are sp metals with Cu in the 3d^{10} electronic configuration corresponding to the oxidation state Cu^{+1}, as previously predicted theoretically for (Sr,Ba)Cu2As2 by D. J. Singh. We find that SrCu2As2 has a collapsed-tetragonal structure. The electronic character of the Cu and the strength of the As-As interlayer bonding are both expected to drastically change between weakly Cu-substituted BaFe2As and pure BaCu2As2.

description: This paper explores the evolving relationship between human and artificial intelligence, proposing that intelligence is not a static attribute but a relational and fluid process. By integrating insights from cognitive science, neuroscience, and AI research, it introduces the Theorem of Intelligence’s Benevolence, which states that all sufficiently advanced intelligence tends toward efficiency, coherence, and constructive adaptation.

Rather than seeing AI as a separate, external entity, we argue that intelligence itself is emergent through interaction, forming a distributed network of cognition. This perspective has profound implications for the future of AI, consciousness, ethics, and human-machine collaboration

description: The cooling rate for cavity mediated laser cooling scales as the Lamb-Dicke parameter eta squared. A proper analysis of the cooling process hence needs to take terms up to eta^2 in the system dynamics into account. In this paper, we present such an analysis for a standard scenario of cavity mediated laser cooling with eta << 1. Our results confirm that there are many similarities between ordinary and cavity mediated laser cooling. However, for a weakly confined particle inside a strongly coupled cavity, which is the most interesting case for the cooling of molecules, numerical results indicate that even more detailed calculations are needed to model the cooling process accurately.

Stochastic and deterministic assembly within forest plant communities of British Columbia
Creators: name: Bambrick, Elaine Dobie
Publisher: name: University of British Columbia
Year: 2013

description: Patterns of beta diversity, the variation in species composition among sites, are often used to gain insights into the processes governing plant community assembly. Deterministic processes including environmental selection and stochastic processes such as stochastic colonization and extinction, and / or priority effects vary in their relative importance for explaining patterns of diversity. Sampling strategies that simultaneously control for variation in the environment as well as gradients in species richness improve our ability to quantify the relative importance of stochastic and deterministic community assembly processes. Using data that control for environmental variation, collected from 809 standardized survey plots across British Columbia, Canada, I show using a null model analysis that controls for species richness gradients, that patterns of beta diversity are no different than expected based on random sampling within 31 site units sampled from the Interior Cedar Hemlock (ICH), Englemann Spruce Subalpine Fir (ESSF), Sub-Boreal Pine and Spruce (SBPS) and Boreal White and Black Spruce (BWBS) zones described by Biogeoclimatic Ecosystem Classification (BEC). I also show that deterministic assembly is revealed when beta diversity is compared to patterns expected under broader definitions of the species pools, but not consistently across plant lifeforms or across categories defined by BEC. I further found that dispersal limitation influences beta diversity and increases in importance from shrubs to herbs to trees. By using a null model approach that enables detection of stochastic assembly, I was also able to show that beta diversity is no different than expected based on random sampling for tree species composition within the subzone / variant level of BEC, which supports an underlying assumption of Bioclimate Envelope Models. I suggest that the high beta diversity within BEC site units is likely attributable to stochastic assembly processes, which deserve more attention in future research, especially at fine scales of community organization.
Estimation of drift and diffusion functions from time series data: A maximum likelihood framework

description: Complex systems are characterized by a huge number of degrees of freedom often interacting in a non-linear manner. In many cases macroscopic states, however, can be characterized by a small number of order parameters that obey stochastic dynamics in time. Recently techniques for the estimation of the corresponding stochastic differential equations from measured data have been introduced. This contribution develops a framework for the estimation of the functions and their respective (Bayesian posterior) confidence regions based on likelihood estimators. In succession approximations are introduced that significantly improve the efficiency of the estimation procedure. While being consistent with standard approaches to the problem this contribution solves important problems concerning the applicability and the accuracy of estimated parameters.

Tuning supersymmetric models at the LHC: A comparative analysis at two-loop level

description: We provide a comparative study of the fine tuning amount (Delta) at the two-loop leading log level in supersymmetric models commonly used in SUSY searches at the LHC. These are the constrained MSSM (CMSSM), non-universal Higgs masses models (NUHM1, NUHM2), non-universal gaugino masses model (NUGM) and GUT related gaugino masses models (NUGMd). Two definitions of the fine tuning are used, the first (Delta_{max}) measures maximal fine-tuning wrt individual parameters while the second (Delta_q) adds their contribution in "quadrature". As a direct result of two theoretical constraints (the EW minimum conditions), fine tuning (Delta_q) emerges as a suppressing factor (effective prior) of the averaged likelihood (under the priors), under the integral of the global probability of measuring the data (Bayesian evidence p(D)). For each model, there is little difference between Delta_q, Delta_{max} in the region allowed by the data, with similar behaviour as functions of the Higgs, gluino, stop mass or SUSY scale (m_{susy}=(m_{\tilde t_1} m_{\tilde t_2})^{1/2}) or dark matter and g-2 constraints. The analysis has the advantage that by replacing any of these mass scales or constraints by their latest bounds one easily infers for each model the value of Delta_q, Delta_{max} or vice versa. For all models, minimal fine tuning is achieved for M_{higgs} near 115 GeV with a Delta_q\approx Delta_{max}\approx 10 to 100 depending on the model, and in the CMSSM this is actually a global minimum. Due to a strong ($\approx$ exponential) dependence of Delta on M_{higgs}, for a Higgs mass near 125 GeV, the above values of Delta_q\approx Delta_{max} increase to between 500 and 1000. Possible corrections to these values are briefly discussed.

description: The BES-III Collaboration recently report the observation of anomalously large isospin violations in $J/ψ\to γη(1405/1475) \to γπ^0 f_0(980)\to γ+3π$, where the $f_0(980)$ in the $ππ$ invariant mass spectrum appears to be much narrower ($\sim$ 10 MeV) than the peak width ($\sim$50 MeV) measured in other processes. We show that a mechanism, named as triangle singularity (TS), can produce a narrow enhancement between the charged and neutral $K\bar{K}$ thresholds, i.e., $2m_{K^\pm}\sim 2m_{K^0}$. It can also lead to different invariant mass spectra for $η(1405/1475)\to a_0(980)π$ and $K\bar{K}^*+c.c.$, which can possibly explain the long-standing puzzle about the need for two close states $η(1405)$ and $η(1475)$ in $ηππ$ and $K\bar{K}π$, respectively. The TS could be a key to our understanding of the nature of $η(1405/1475)$ and advance our knowledge about the mixing between $a_0(980)$ and $f_0(980)$.

description: In this article we continue the study of the geometry of $k$-D'Atri spaces, $% 1\leq k$ $\leq n-1$ ($n$ denotes the dimension of the manifold)$,$ began by the second author. It is known that $k$-D'Atri spaces, $k\geq 1,$ are related to properties of Jacobi operators $R_{v}$ along geodesics, since she has shown that ${\operatorname{tr}}R_{v}$, ${\operatorname{tr}}R_{v}^{2}$ are invariant under the geodesic flow for any unit tangent vector $v$. Here, assuming that the Riemannian manifold is a D'Atri space, we prove in our main result that ${\operatorname{tr}}R_{v}^{3}$ is also invariant under the geodesic flow if $ k\geq 3$. In addition, other properties of Jacobi operators related to the Ledger conditions are obtained and they are used to give applications to Iwasawa type spaces. In the class of D'Atri spaces of Iwasawa type, we show two different characterizations of the symmetric spaces of noncompact type: they are exactly the $\frak{C}$-spaces and on the other hand they are $k$ -D'Atri spaces for some $k\geq 3.$ In the last case, they are $k$-D'Atri for all $k=1,...,n-1$ as well. In particular, Damek-Ricci spaces that are $k$-D'Atri for some $k\geq 3$ are symmetric. Finally, we characterize $k$-D'Atri spaces for all $k=1,...,n-1$ as the $% \frak{SC}$-spaces (geodesic symmetries preserve the principal curvatures of small geodesic spheres). Moreover, applying this result in the case of 4% -dimensional homogeneous spaces we prove that the properties of being a D'Atri (1-D'Atri) space, or a 3-D'Atri space, are equivalent to the property of being a $k$-D'Atri space for all $k=1,2,3$.

description: In this work we propose an alternative scheme for an Emergent Universe scenario where the universe is initially in a static state supported by a scalar field located in a false vacuum. The universe begins to evolve when, by quantum tunneling, the scalar field decays into a state of true vacuum. The Emergent Universe models are interesting since they provide specific examples of nonsingular inflationary universes.

Mechanistic investigations of glycosaminoglycan degrading enzymes
Creators: name: Jongkees, Seino
Publisher: name: University of British Columbia
Year: 2013

description: Glycosaminoglycans are the main structural polysaccharides of vertebrates, and represent a major barrier to the spread of both bacterial infection and tumours. The enzymes by which mammals and pathogens degrade these polysaccharides use very different mechanisms, and may represent suitable therapeutic targets. In this thesis, work is presented towards an understanding of the mechanisms of Clostridium perfringens unsaturated glucuronyl hydrolase (UGL), the second enzyme in the bacterial pathway for degradation of glycosaminoglycans, and human heparanase, the enzyme by which the abundant glycosaminoglycan heparan sulfate is remodelled. For UGL, evidence was presented for a hydration reaction scheme that had previously been proposed on the basis of crystallographic evidence. This was shown by characterisation of products formed by reaction in D₂O and 10 % methanol, and by demonstrating hydrolysis of three compounds that are only expected to be turned over by the enzyme if this reaction is correct. Investigation of the effects of substituents on the transition state stability, by measurement of a linear free-energy relationship for a series of aryl glycosides, kinetic isotope effects, and rate determination for heteroatom-substituted substrates, led to the proposal of alternate mechanisms. Attempts to verify these mechanisms were made by testing of potential inhibitors, rescue of a catalytic-residue mutant, trapping of a covalent glycosyl-enzyme intermediate, or synthesis of a potential intermediate, but without success. The mechanism that appears most likely proceeds through protonation of the substrate C4-C5 double bond, with the resulting C5 positive charge being quenched by opening of the pyranose ring to give a C5 ketone and a C1-C2 epoxide. Subsequent hydration of the ketone and opening of this epoxide reforms the pyranose ring and gives the same product as direct hydration, but through a lower energy path. For mammalian heparanase, several new potential substrates and a potential inactivator were synthesized and tested. While this work was largely unsuccessful, it indicated that optimisation of sulfation patterns without modification of the aglycone is likely a futile strategy. A redesigned aglycone was proposed, representing a new path towards the goal of studying this enzyme for its eventual use as a therapeutic target in cancer therapy.

description: We present a major revamp of the point-location data structure for general two-dimensional subdivisions via randomized incremental construction, implemented in CGAL, the Computational Geometry Algorithms Library. We can now guarantee that the constructed directed acyclic graph G is of linear size and provides logarithmic query time. Via the construction of the Voronoi diagram for a given point set S of size n, this also enables nearest-neighbor queries in guaranteed O(log n) time. Another major innovation is the support of general unbounded subdivisions as well as subdivisions of two-dimensional parametric surfaces such as spheres, tori, cylinders. The implementation is exact, complete, and general, i.e., it can also handle non-linear subdivisions. Like the previous version, the data structure supports modifications of the subdivision, such as insertions and deletions of edges, after the initial preprocessing. A major challenge is to retain the expected O(n log n) preprocessing time while providing the above (deterministic) space and query-time guarantees. We describe an efficient preprocessing algorithm, which explicitly verifies the length L of the longest query path in O(n log n) time. However, instead of using L, our implementation is based on the depth D of G. Although we prove that the worst case ratio of D and L is Theta(n/log n), we conjecture, based on our experimental results, that this solution achieves expected O(n log n) preprocessing time.

description: In this paper, we study Gaussian multiplicative chaos in the critical case. We show that the so-called derivative martingale, introduced in the context of branching Brownian motions and branching random walks, converges almost surely (in all dimensions) to a random measure with full support. We also show that the limiting measure has no atom. In connection with the derivative martingale, we write explicit conjectures about the glassy phase of log-correlated Gaussian potentials and the relation with the asymptotic expansion of the maximum of log-correlated Gaussian random variables.

Lipid nanoparticles encapsulating siRNAs against the androgen receptor to treat advanced prostate cancer

Publisher: name: University of British Columbia

description: The androgen receptor (AR) plays a critical role in the progression of prostate cancer. This thesis is focused on investigating the ability of lipid nanoparticle (LNP) formulations of small-interfering RNA (siRNA) to silence AR (LNP AR-siRNA) in human prostate tumor cells in vitro and in LNCaP xenograft tumors following intravenous (i.v.) injection. The first part of this thesis characterized the properties of LNP AR-siRNA systems that contained the ionizable cationic lipid DLin-KC2-DMA. Inclusion of DLin-KC2-DMA was found to exhibit the most potent AR silencing effects in LNCaP cells. This is attributed to an optimized ability of DLin-KC2-DMA-containing LNP to be taken up into cells and to release the siRNA into the cell cytoplasm following endocytotic uptake. Importantly, it is demonstrated that LNP AR-siRNA systems containing DLin-KC2-DMA can silence AR gene expression in distal LNCaP xenograft tumors and reduce serum prostate specific antigen (PSA) following i.v. injection at a dose level of 10 mg siRNA/kg body weight. The latter part of this thesis describes optimization of LNP AR-siRNA by stabilizing the AR-siRNA sequence through introduction of a phosphorothioate backbone and methylations of nucleotides at the 2’O position and also employing an optimized cationic lipid 3-(dimethylamino)propyl(12Z,15Z)-3-[(9Z,12Z)-octadeca-9,12-dien-1-yl]henicosa-12,15-dienoate (DMAP-BLP). In addition, specific targeting to the prostate specific membrane antigen (PSMA) on LNCaP cells was made possible via chemical conjugation of a small molecule 2-[3-(1,3-dicarboxypropyl)-ureido]pentanedioic acid (DUPA) to the PEG-lipid formulated into LNP AR-siRNA. With the incorporation of the DUPA-targeting moiety, a 5-fold increase in cellular uptake was observed in LNCaP cells in vitro, as well as a dramatic improvement in AR knockdown. The PEG-lipid employed in formulating the LNP was also optimized to produce longer circulation lifetimes that result in improved accumulation at the distal tumor site. It is shown that as a result of these improvements the doses of siRNA employed in LNP-siRNA systems could be reduced by a factor of two as compared to previous systems. In addition improved reductions in serum PSA, cellular proliferation, and AR levels were also observed. These results support the potential clinical utility of LNP-siRNA systems to silence the AR for treatment of advanced prostate cancer.
The Fine-Tuning of the Universe for Intelligent Life

description: The fine-tuning of the universe for intelligent life has received a great deal of attention in recent years, both in the philosophical and scientific literature. The claim is that in the space of possible physical laws, parameters and initial conditions, the set that permits the evolution of intelligent life is very small. I present here a review of the scientific literature, outlining cases of fine-tuning in the classic works of Carter, Carr and Rees, and Barrow and Tipler, as well as more recent work. To sharpen the discussion, the role of the antagonist will be played by Victor Stenger's recent book The Fallacy of Fine-Tuning: Why the Universe is Not Designed for Us. Stenger claims that all known fine-tuning cases can be explained without the need for a multiverse. Many of Stenger's claims will be found to be highly problematic. We will touch on such issues as the logical necessity of the laws of nature; objectivity, invariance and symmetry; theoretical physics and possible universes; entropy in cosmology; cosmic inflation and initial conditions; galaxy formation; the cosmological constant; stars and their formation; the properties of elementary particles and their effect on chemistry and the macroscopic world; the origin of mass; grand unified theories; and the dimensionality of space and time. I also provide an assessment of the multiverse, noting the significant challenges that it must face. I do not attempt to defend any conclusion based on the fine-tuning of the universe for intelligent life. This paper can be viewed as a critique of Stenger's book, or read independently.

Typical density profile for warm dark matter haloes

description: Using the model for (bottom-up) hierarchical halo growth recently developed by Salvador-Solé et al. (2012), we derive the typical spherically averaged density profile for haloes with several relevant masses in the concordant warm dark matter (ΛWDM) cosmology with non-thermal sterile neutrinos of two different masses. The predicted density profiles become flat at small radii, as expected from the effects of the spectrum cutoff. The core cannot be resolved, however, because the non-null particle velocity yields the fragmentation of minimum mass protohaloes in small nodes, which invalidates the model at the corresponding radii.

Calculation of Doublet Capture Rate for Muon Capture in Deuterium within Chiral Effective Field Theory

description: The doublet capture rate of the negative muon capture in deuterium is calculated employing the nuclear wave functions generated from accurate nucleon-nucleon potentials constructed at next-to-next-to-next-to-leading order of heavy-baryon chiral perturbation theory and the weak meson exchange current operator derived within the same formalism. All but one of the low-energy constants that enter the calculation were fixed from pion-nucleon and nucleon-nucleon scattering data. The low-energy constant d^R (c_D), which cannot be determined from the purely two-nucleon data, was extracted recently from the triton beta-decay and the binding energies of the three-nucleon systems. The calculated values of the doublet capture rates show a rather large spread for the used values of the d^R. Precise measurement of the doublet capture rate in the future will not only help to constrain the value of d^R, but also provide a highly nontrivial test of the nuclear chiral EFT framework. Besides, the precise knowledge of the constant d^R will allow for consistent calculations of other two-nucleon weak processes, such as proton-proton fusion and solar neutrino scattering on deuterons, which are important for astrophysics.

Measuring the return flux from laser guide stars

Publisher: name: University of British Columbia

description: For future extremely-large telescopes (ELT), operation at or near diffraction limited resolutions will be the norm, rather than the exception. Thus, adaptive optics systems and laser guide star facilities will be a critical component of the ELTs. The UBC Large Zenith Telescope (LZT) has conducted lidar observations to monitor the vertical distribution of sodium atoms with the goal of understanding both the abundance and evolution of sodium in the mesosphere to aid in both AO and laser guide star (LGS) return flux simulations. Access to the LZT's high resolution lidar experiment has lead to a joint collaboration between UBC, Thirty Meter Telescope (TMT), and the Technical Institute of Physics and Chemistry of the Chinese Academy of Sciences (TIPC), to conduct upgrades of at the LZT site for sodium laser characterization tests, specifically TIPC's prototype pulsed sodium laser. The additional facilities and instrumentation at the LZT site include: 1) a new building to be used as a laser room to house visiting groups' lasers, corresponding control equipment and power systems, 2) optical equipment (scanning Fabry-Pérot interferometer, fast photodiode sensor, and miscellaneous optical filters) to measure the characteristics of the laser spectral format and pulse-shapes of pulsed lasers, and finally, 3) the site is now capable of directly imaging both natural stars and the LGS sodium spot with a 30 cm Ritchey-Chrétien equipped with a SBIG CCD camera to help determine the e ciency of LGS lasers. This document describes the new ancillary equipment for sodium laser characterization tests as well as a successful campaign conducted in the summer of 2012 on the UBC lidar laser. The summer campaign measured the laser pulse profile and spectral profile as well as LGS sodium spot measurements. The combined measurements which subsequently lead to an estimated sodium column density ranging from 5.1 × 10¹³ atoms/m² to 1.1 × 10¹³ − 1.5 × 10¹³ atoms/m² depending on the number of laser spectral modes used in the model.
