description: A new exactly solvable model for the evolution of relativistic kinetic system interacting with an internal stochastic reservoir under the influence of a gravitational background expansion is established. This model of self-interaction is based on the relativistic kinetic equation for the distribution function defined in the extended phase space. The supplementary degree of freedom is described by the scalar stochastic variable (Langevin source), which is considered to be the constructive element of the effective one-particle force. The expansion of the Universe is shown to be accelerated for the suitable choice of the non-minimal self-interaction force.

General neutrino interactions with sterile neutrinos in light of coherent neutrino-nucleus scattering and meson invisible decays

description: In this work we study the current bounds from the CEνNS process and meson invisible decays on generic neutrino interactions with sterile neutrinos in effective field theories. The interactions between quarks and left-handed SM neutrinos and/or right-handed neutrinos are first described by the low-energy effective field theory (LNEFT) between the electroweak scale and the chiral symmetry breaking scale. We complete the independent operator basis for the LNEFT up to dimension-6 by including both the lepton-number-conserving (LNC) and lepton-number-violating (LNV) operators involving right-handed neutrinos. We translate the bounds on the LNEFT Wilson coefficients from the COHERENT observation and calculate the branching fractions of light meson invisible decays. The bounds on LNEFT are then mapped onto the SM effective field theory with sterile neutrinos (SMNEFT) to constrain new physics above the electroweak scale. We find that the meson invisible decays can provide the only sensitive probe for τ neutrino flavor component and s quark component in the quark-neutrino interactions involving two (one) active neutrinos and for the effective operators without any active neutrino fields. The CEνNS process places the most stringent bound on all other Wilson coefficients. By assuming one dominant Wilson coefficient at a time in SMNEFT and negligible sterile neutrino mass, the most stringent limits on the new physics scale are 2.7 - 10 TeV from corresponding dipole operator in LNEFT and 0.5 - 1.5 TeV from neutrino-quark operator in LNEFT.

Exploring the Unfolding of Dynamic Effects with Continuous-Time Models: Recommendations Concerning Statistical Power to Detect Peak Cross-Lagged Effects

subject: cross-lagged effects

subject: time series
subject: 519 Wahrscheinlichkeiten und angewandte Mathematik

description: Cross-lagged panel models have been commonly applied to investigate the dynamic interplay of variables. In such discrete-time models, the size of the cross-lagged effects depends on the length of the time interval between the measurement occasions. Continuous-time modeling allows to explore this interval dependence of cross-lagged effects and thus to identify the maximal “peak” cross-lagged effects. To detect these peak effects, sufficient statistical power is needed. Based on results from a simulation study, we employed machine learning algorithms to identify a highly accurate prediction model. Results are incorporated into a Shiny App (available at https://psychtools.shinyapps.io/ContinuousTimePowerCalculation) for easy power calculations. Although limitations apply, our results might be helpful for study planning.
title: Sound Propagation in Inhomogeneous Media
Creators: name: Taherzadeh, Shahram
Publisher: name: The Open University
Year: 1997

description: Outdoor sound propagation is of interest in community noise problems, for example noise prediction. The interaction of sound with the ground is also of interest in remote surveillance by acoustic and seismic sensors. In this thesis, previous work concerned with sound propagating in a layered refracting atmosphere, and with acoustic-to-seismic coupling is reviewed and extended. The thesis makes contributions in several areas concerned with these topics. Specifically - methods of predicting propagation in a variable sound velocity gradients are reviewed and a new formulation is advanced; - a program FFLAGS (Fast Field program for Layered Air Ground Systems) is reviewed and revised to improve numerical efficiency and enable wider application; - the Biot theory of wave propagation in poro-elastic media is reviewed and contrasted with a recent theory advanced by de la Cruz and Spanos, particularly in respect of boundary conditions; - the influence of porosity on wave propagation in fluid-saturated porous elastic media is investigated using predictions based on Biot's theory. It is found that there are large difference between predictions for air-filled soils and water-saturated sediments. It is also predicted that porosity plays an important role in determining the wave speed, especially in water-saturated sediments; - the influence of porosity on acoustic-to-seismic coupling is investigated. It is found that a) it is possible to obtain improved agreement with data on the frequencies of maximum acoustic-to-seismic coupling, and, b) it is possible to obtain tolerable agreement with new data on acoustic-to-seismic coupling spectra; - a new method of measuring excess attenuation spectrum of sound using MLSSA (Maximum length Sequence System Analyser) is described and used to investigate the field due to a dipole source over an impedance plane; - directivity effects over an impedance or poroelastic plane are explored using the FFP formulation, asymptotic approximations and laboratory experiments. The over all theme of this thesis is the study of the influence of inhomogeneities in the medium on sound wave propagation. Because of the multiplicity of topics, relevant literature reviews are included in each of the chapters.
Resolving nonuniform temperature distributions with single-beam absorption spectroscopy. Part I: Theoretical capabilities and limitations

description: Absorption spectroscopy is traditionally used to determine the average gas temperature and species concentration along the laser line-of-sight by measuring the magnitude of two or more absorption transitions with different temperature dependence. Previous work has shown that the nonlinear temperature dependence of the absorption strength of each transition, set by the lower-state energy, E", can be used to infer temperature variations along the laser line-of-sight. In principle, measuring more absorption transitions with broader bandwidth light sources improves the ability to resolve temperature variations. Here, we introduce a singular value decomposition framework in order to explore the theoretical limits to resolving temperature distributions with single-beam line-of-sight absorption measurements. We show that in the absence of measurement noise or error, only the first ~14 well-selected absorption features improve the temperature resolution, and a Tikhonov regularization method improves the accuracy of the temperature inversion, particularly for recovery of the maximum gas temperature along the laser beam. We use inversion simulations to demonstrate that one can resolve a selection of temperature distributions along a laser beam line-of-sight to within 3% for the sample cases analyzed. In part II of this work, we explore the influence of measurement noise and error, and experimentally demonstrate the technique to show that there is benefit to measuring additional absorption transitions under real conditions.

Beyond Time V: Closing the Gaps in Emergent Temporality
Creators: name: Yildirim, Kubilay
Publisher: name: Zenodo
Year: 2025

description: Abstract:

This fifth paper in the Beyond Time series establishes the mathematical foundation for a new model of time as an emergent phenomenon. Building upon the theoretical framework developed in previous installments, it introduces a set of axioms and formal equations that define time not as a fundamental dimension, but as a scalar field (τ\tauτ) arising from entropy-driven, distinguishable state transitions. Time, in this view, emerges only when energy exchange and informational differentiation occur, and vanishes near the physical boundaries defined by the speed of light (ccc) and absolute zero temperature (T0T_0T0). This paper addresses key gaps left open in Beyond Time IV by deriving limit conditions, proposing a Gedankenexperiment, and outlining falsifiable implications. The resulting model repositions time as a local and statistical construct—one that may cease, emerge, or vary based on a system’s thermodynamic behavior.

description: We investigate the effective case of two-flavor neutrino oscillations in infinitely dense matter by using a perturbative approach. We begin by briefly summarizing the conditions for the three-flavor neutrino oscillation probabilities to take on the same form as the corresponding two-flavor probabilities. Then, we proceed with the infinitely dense matter calculations. Finally, we study the validity of the approximation of infinitely dense matter when the effective matter potential is large, but not infinite, this is done by using both analytic and numeric methods.

Evaluation of the electronic document and record management program in a Canadian municipality
Creators: name: Xie, Li
Publisher: name: University of British Columbia
Year: 2010

description: An electronic record management system (ERMS) is an application designed to improve the management of current electronic records in organizations. It is frequently integrated with an electronic document management system (EDMS), and thus becomes an electronic document/record management system (EDRMS). Document and record are different concepts in archival science and require different handling. Managing electronic documents focuses on bringing in organizations business-related benefits, such as enhanced information sharing and increased office productivity. Managing electronic records focuses on ensuring records reliability and authenticity. The development of EDMS is an industry response to the proliferation of electronic documents brought by digital technologies, while the development of ERMS involves research on the nature of electronic records, how to distinguish them from other electronic information, and how to protect their evidentiary value. Standards such as the DoD5015.2 specify functional requirements for designing an ERMS. Authoritative organizations test functionalities of commercial electronic records management systems, verifying their compliance with standards. There are, however, few systematic investigations done to evaluate the effectiveness of standard-compliant systems with respect to their operation in organizations. This thesis attempts to determine whether an EDRMS implemented in a Canadian municipality has achieved the goals set for its implementation. Currently, there are no standardized methods or services assessing the performance of either document or record management functions in an EDRMS. This thesis employs program evaluation, in particular, theory-driven program evaluation, as methodological framework, to assess the components of the city’s EDRMS program. The research is designed as a survey and data are collected using a questionnaire. The evaluation questions were addressed to a particularly defined group of respondents, the users of the system who are charged with records management responsibilities in their offices or departments. Findings are reported in the form of summarized statistics. The evaluation concludes that the EDRMS program is an overall success in regards of both managing electronic documents and electronic records for this group of users. Further analyses and discussions of the findings identify issues and areas requiring improvements as well as suggest recommendations.

description: A toroidal dipole represents an often overlooked electromagnetic excitation distinct from the standard electric and magnetic multipole expansion. We show how a simple arrangement of strongly radiatively coupled atoms can be used to synthesize a toroidal dipole where the toroidal topology is generated by radiative transitions forming an effective poloidal electric current wound around a torus. We extend the protocol for methods to prepare a delocalized collective excitation mode consisting of a synthetic lattice of such toroidal dipoles and a non-radiating, yet oscillating charge-current configuration, dynamic anapole, for which the far-field radiation of a toroidal dipole is identically canceled by an electric dipole.
title: Acoustic measurements of flowing and quasi-static particulate suspensions
Creators: name: Moss, Simon H. O.
Publisher: name: The Open University
Year: 1997

description: Flowing suspensions of solid particles in gas can be found in various industrial applications, as a method for transporting powdered solids (known as "pneumatic conveying"). The problem of measuring the mass concentration of the solid fraction has not yet been satisfactorily resolved. This thesis explores acoustic techniques to measure the particle concentration. Controlled suspensions -- both flowing and quasi-static - were generated in cylindrical tubes, and their acoustic properties were measured over three frequency ranges, requiring a variety of different measuring techniques: Plane wave region (200 -4 kHz): the attenuation of plane waves travelling along the flow tube was measured. A simple method of measuring the characteristic impedance of the suspension was also devised and preliminary measurements were made. Reverberant region (4 - 20 kHz). Three parameters were measured: the decay rate of the reverberant field in certain frequency bands; the level of actively-excited steady state sound; and the frequency of transverse resonant modes of the pipe. Ultrasonic region (40 - 75 kHz): the attenuation of ultrasound was measured across the pipe diameter. The measurements were compared with theoretical predictions. They showed the predicted linearity of acoustic attenuation with concentration, although the frequency dependence was less well predicted. In general, the larger particle sizes produced the greatest discrepancy; an explanation is proposed. Ultrasonic measurements showed significant differences from the predicted frequency dependence. A method of isolating acoustic transducers from the flow with a column of clean air is described. However, measurements may be complicated by interactions at the orifice into the flow pipe. Further work is needed in this area. It is concluded that acoustic methods could be used to measure particle concentration. However, to remain insensitive to changes in the properties of the particles - size in particular - measurements must be made at more than one frequency.

We then prove that if a Calabi-Yau manifold is sufficiently volume collapsed with bounded diameter and sectional curvature, then it admits a Ricci-flat Kähler metrictogether with a compatible pure nilpotent Killing structure: this is related to an open question of Cheeger, Fukaya and Gromov.

title: Models for sound propagation in suspensions and emulsions
Creators: name: Evans, Jonathan M.
Publisher: name: The Open University
Year: 1996

description: Theoretical and experimental work on sound propagation in suspensions and emulsions is reviewed. Three theoretical approaches are identified: scattering theory, coupled phase theory and porous media theory. Coupled phase theory is extended and compared analytically and numerically to scattering and porous media theory. Important regimes of scattering theory - the lossless and viscothermal scattering, single and multiple scattering and incoherent scattering regimes - are examined. Experimental data is used to corroborate lossless multiple scattering theory in the short wavelength, high volume fraction region. Previous coupled phase theories have modelled sound propagation in two phase media (i) with heat transfer assuming incompressible particles and (ii) with a compressible particulate phase neglecting heat transfer. Type (i) models are examined analytically and compared to scattering theory. Types (i) and (ii) are compared and brought together in a more general coupled phase theory. The new theory provides an alternative model to scattering theory for sound propagation in emulsions. Predictions of the new theory are compared to experimental data and predictions of scattering theory. Conditions for the equivalence of the frameless Biot porous media theory and coupled phase theory are identified. Predictions of the two approaches are compared to experimental data. New measurements of pore size distribution are used to predict measured acoustical properties of air saturated glass beads. Other extensions to coupled phase theory are reviewed and developed. Predictions including the effect of high volume fraction on the drag and the induced mass force are compared to experimental data and predictions of porous media theory. Coupled phase theory including heat transfer is extended to include particle size distributions; predictions of tl-ds are compared to measurements. The effect of non-spherical particles is investigated. Using the theory of Culick, frequency shifts for modes in an enclosure into which a suspension has been introduced are calculated. These are compared to the predictions of an intuitive approach. The method of Margulies and Schwartz for modelling particle diffusion is discussed. Areas where further work is required are identified.

description: We present a new technique for identifying stellar mass black holes in low mass X-ray binaries (LMXBs), and apply it to XMM-Newton observations of M31. We examine X-ray time series variability seeking power density spectra (PDS) typical of LMXBs accreting at a low accretion rate (which we refer to as Type A PDS); these are very similar for black hole and neutron star LMXBs. Galactic neutron star LMXBs exhibit Type A PDS at low luminosities (~10^36--10^37 erg/s) while black hole LMXBs can exhibit them at luminosities >10^38 erg/s. We propose that Type A PDS are confined to luminosities below a critical fraction of the Eddington limit, $l_c$ that is constant for all LMXBs; we have examined asample of black hole and neutron star LMXBs and find they are all consistent with $l_c$ = 0.10+/-0.04 in the 0.3--10 keV band. We present luminosity and PDS data from 167 observations of X-ray binaries in M31 that provide strong support for our hypothesis. Since the theoretical maximum mass for a neutron star is \~3.1 M_Sun, we therefore assert that any LMXB that exhibits a Type A PDS at a 0.3--10 keV luminosity greater than 4 x 10^37 erg/s is likely to contain a black hole primary. We have found eleven new black hole candidates in M31 using this method. We focus on XMM-Newton observations of RX J0042.4+4112, an X-ray source in M31 and find the mass of the primary to be 7+/-2 M_Sun, if our assumptions are correct. Furthermore, RX J0042.4+4112 is consistently bright in \~40 observations made over 23 years, and is likely to be a persistently bright LMXB; by contrast all known Galactic black hole LMXBs are transient. Hence our method may be used to find black holes in known, persistently bright Galactic LMXBs and also in LMXBs in other galaxies.

Using an in-plane magnetic field of variable strength and orientation, we are able to obtain information on the quasi-particle wave functions in momentum space for 1 to 6 electrons per dot. For the lowest two energy states, we find a good agreement with Gaussian functions for a harmonic potential. The high energy orbitals exhibit signatures of anisotropic confinement and correlation effects.

description: We study the effects of an external electric field on both the motion of the reaction zone and the spatial distribution of the reaction product, $C$, in an irreversible $A^- +B^+ \to C$ reaction-diffusion process. The electrolytes $A\equiv (A^+,A^-)$ and $B\equiv (B^+,B^-)$ are initially separated in space and the ion-dynamics is described by reaction-diffusion equations obeying local electroneutrality. Without an electric field, the reaction zone moves diffusively leaving behind a constant concentration of $C$-s. In the presence of an electric field which drives the reagents towards the reaction zone, we find that the reaction zone still moves diffusively but with a diffusion coefficient which slightly decreases with increasing field. The important electric field effect is that the concentration of $C$-s is no longer constant but increases linearly in the direction of the motion of the front. The case of an electric field of reversed polarity is also discussed and it is found that the motion of the front has a diffusive, as well as a drift component. The concentration of $C$-s decreases in the direction of the motion of the front, up to the complete extinction of the reaction. Possible applications of the above results to the understanding of the formation of Liesegang patterns in an electric field is briefly outlined.

description: Short and long range interactions between earthquakes are attracting increasing interest. Scale invariant properties of seismicity in time, space and energy argue for the presence of complex triggering mechanisms where, like a cascade process, each event produces aftershocks. A definitive method to assess any connection between two earthquakes separated in time and distance does not exist. Here we propose a novel method of data analysis that, based on the space-time combined generalization of the correlation integral leads to a self-consistent visualization and analysis of both spatial and temporal correlations. When analyzing global seismicity we discovered a universal relation linking the spatial Influence Length of a given earthquake to the time elapsed from the event itself. Following an event, time correlations (i.e. causality effects) exist in a region that shrinks over time, suggesting a long-range dissipating stress transfer. A different process is acting in the short-range where events are randomly set, evidencing a sub-diffusive growth of the seismogenic zone.

description: In this study, we present new insights on the origin of the high-field Q-slope in superconducting radio-frequency cavities. Consequent hydrofluoric acid rinses are used to probe the radio-frequency performance as a function of the material removal of two superconducting bulk niobium cavities prepared with low temperature nitrogen infusion. The study reveals that nitrogen infusion affects only the first few tens of nanometers below the native oxide layer. The typical high-field Q-slope behavior of electropolished cavities is indeed completely recovered after a dozen hydrofluoric acid rinses. The reappearance of the high-field Q-slope as a function of material removal was modeled by means of London's local description of screening currents in the superconductor, returning good fitting of the experimental data and suggesting that interstitial impurities layers with diffusion length of the order to tens of nanometers can mitigate high-field Q-slope.

Hearing the shape of inequivalent spin structures and exotic Dirac operators

description: Exotic spinor fields arise from inequivalent spin structures on non-trivial topological manifolds, $M$. This induces an additional term in the Dirac operator, defined by the cohomology group $H^1(M,\mathbb{Z}_2)$ that rules a Cech cohomology class. This formalism is extended for manifolds of any finite dimension, endowed with a metric of arbitrary signature. The exotic corrections to heat kernel coefficients, relating spectral properties of exotic Dirac operators to the geometric invariants of $M$, are derived and scrutinized.

Photon propagation in non-trivial backgrounds

description: Propagation of photons (or of any spin-1 boson) is of interest in different kinds of non-trivial background, including a thermal bath, or a background magnetic field, or both. We give a unified treatment of all such cases, casting the problem as a matrix eigenvalue problem. The matrix in question is not a normal matrix, and therefore care should be given to distinguish the right eigenvectors from the left eigenvectors. The polarization vectors are shown to be right eigenvectors of this matrix, and the polarization sum formula is seen as the completeness relation of the eigenvectors. We show how this method is successfully applied to different non-trivial backgrounds.

Large-scale benchmark study of survival prediction methods using multi-omics data

description: Multi-omics data, that is, datasets containing different types of high-dimensional molecular variables (often in addition to classical clinical variables), are increasingly generated for the investigation of various diseases. Nevertheless, questions remain regarding the usefulness of multi-omics data for the prediction of disease outcomes such as survival time. It is also unclear which methods are most appropriate to derive such prediction models. We aim to give some answers to these questions by means of a large-scale benchmark study using real data. Different prediction methods from machine learning and statistics were applied on 18 multi-omics cancer datasets from the database "The Cancer Genome Atlas", containing from 35 to 1,000 observations and from 60,000 to 100,000 variables. The considered outcome was the (censored) survival time. Twelve methods based on boosting, penalized regression and random forest were compared, comprising both methods that do and that do not take the group structure of the omics variables into account. The Kaplan-Meier estimate and a Cox model using only clinical variables were used as reference methods. The methods were compared using several repetitions of 5-fold cross-validation. Uno's C-index and the integrated Brier-score served as performance metrics. The results show that, although multi-omics data can improve the prediction performance, this is not generally the case. Only the method block forest slightly outperformed the Cox model on average over all datasets. Taking into account the multi-omics structure improves the predictive performance and protects variables in low-dimensional groups - especially clinical variables - from not being included in the model. All analyses are reproducible using freely available R code.

Theory of three-magnon interaction in a vortex-state magnetic nanodot

description: We use vector Hamiltonian formalism (VHF) to study theoretically three-magnon parametric interaction (or three-wave splitting) in a magnetic disk existing in a magnetic vortex ground state. The three-wave splitting in a disk is found to obey two selection rules: (i) conservation of the total azimuthal number of the resultant spin-wave modes, and (ii) inequality for the radial numbers of interacting modes, if the mode directly excited by the driving field is radially symmetric (i.e. if the azimuthal number of the directly excited mode is $m = 0$). The selection rule (ii), however, is relaxed in the "small" magnetic disks, due to the influence of the vortex core. We also found, that the efficiency of the three-wave interaction of the directly excited mode strongly depends on the azimuthal and radial mode numbers of the resultant modes, that becomes determinative in the case when several splitting channels (several pairs of resultant modes) simultaneously approximately satisfy the resonance condition for the splitting. The good agreement of the VHF analytic calculations with the experiment and micromagnetic simulations proves the capability of the VHF formalism to predict the actual splitting channels and the magnitudes of the driving field thresholds for the three-wave splitting.

title: Postnatal growth rates of the dwarf hippo Phanourios minor from the Pleistocene of Cyprus
Creators: name: van Heteren, Anneke H.

description: Cyprus, in the Pleistocene, was extremely isolated from a geological and biogeographical point of view. Only two macromammals successfully colonised the island before the Holocene: Elephas cypriotes, approximately 1.4 metres tall at the withers, and Phanourios minor. The latter is the smallest dwarfed hippo ever found; it stood 70 centimetres at the withers and weighed an estimated 200 kilograms, approximately 10% of its mainland ancestor’s weight. The main objective of this study was to determine the mode of dwarfing in hippopotami from Cyprus using bone histology. Radii and several other long bones of P. minor, and their normal sized relatives (Hippopotamus amphibius), were thin-sectioned and studied under a polarizing optical microscope. Type of bone matrix and counts of lines of arrested growth (LAGs) served as proxies for development rate and time. Histological analyses suggest that Cypriot dwarfed hippos had slower postnatal growth rates than their normal-sized relatives. In fact, Cypriot dwarfed hippos would have needed at least two decades to reach adult size as demonstrated by the radius. Slow growth might have been selected for in a resource-limited but predator-free environment.
