Correlated Lévy noise in linear dynamical systems
Creators: name: Srokowski, Tomasz
Publisher: name: arXiv
Year: 2010
Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)
subject: FOS: Physical sciences

description: Linear dynamical systems, driven by a non-white noise which has the Levy distribution, are analysed. Noise is modelled by a specific stochastic process which is defined by the Langevin equation with a linear force and the Levy distributed symmetric white noise. Correlation properties of the process are discussed. The Fokker-Planck equation driven by that noise is solved. Distributions have the Levy shape and their width, for a given time, is smaller than for processes in the white noise limit. Applicability of the adiabatic approximation in the case of the linear force is discussed.

description: Amid the global shift toward digital transformation in financial governance, the integration of Artificial Intelligence (AI) in accounting policy formation has emerged as a critical area for reform in Ghana. This study addresses the pressing need for adaptive and transparent financial governance by evaluating the challenges regulators and corporate boards face in adopting AI technologies. Using a descriptive research design, the study analyzed secondary data from 50 institutions—including 25 corporate boards and 25 regulatory bodies—collected through institutional reports and analyzed via chi-square tests, ANOVA, correlation, and multiple regression. The findings reveal that AI integration has significantly improved accounting policy outcomes. AI-based data analytics enhanced policy quality, with automated dashboards and visualization tools showing the highest effectiveness (ANOVA significance, p < 0.01). Regulatory enforcement improved, as fraud detection speed increased by 37.5%, compliance accuracy by 21.4%, and reporting efficiency by 33.3%. Machine learning tools accelerated policy revisions by 41.7%, reducing revision time from 12 to 7 months. The overall Pearson correlation coefficient between AI integration and policy performance was r = 0.801, while the regression model explained 72.4% of the variance (R² = 0.724) in policy outcomes. The study concludes that AI tools are transformative assets for both private and public accounting governance in Ghana. It recommends scaling user-friendly AI systems, investing in AI literacy, and developing a cohesive digital policy framework. These insights offer a strategic pathway for AI-driven reform and contribute empirical evidence to the growing discourse on digital transformation in emerging economies.
Orbital angular momentum induced beam shifts

description: We present experiments on Orbital Angular Momentum (OAM) induced beam shifts in optical reflection. Specifically, we observe the spatial Goos-Hänchen shift in which the beam is displaced parallel to the plane of incidence and the angular Imbert-Fedorov shift which is a transverse angular deviation from the geometric optics prediction. Experimental results agree well with our theoretical predictions. Both beam shifts increase with the OAM of the beam; we have measured these for OAM indices up to 3. Moreover, the OAM couples these two shifts. Our results are significant for optical metrology since optical beams with OAM have been extensively used in both fundamental and applied research.

THE MARITIME COMMUNITY OF LA CIOTAT (1851 - 1914)
Creators: name: Vasilaki Kalliopi
Publisher: name: Zenodo
Year: 2021

description: he transition from sail to steam in La Ciotat has affected profoundly the city and shaped its maritime community towards an industrial pattern. The port of La Ciotat has been transformed in one of the most important modern shipbuilding centres in Southern France, particularly after the acquisition of the shipyards by the Compagnie des Messageries Maritimes, in 1851. This paper aims to present, through a demographic approach, the transformation process and the profound change of the maritime community of La Ciotat from 1851 to 1914. I will focus on three primary sources, all elaborated through FastCat: the nominative lists of the population censuses for the years 1831, 1851 and 1911; the registers of the workforce at the shipyards of Messageries Maritimes in the years between 1851 and 1912; and the seamen registers of Inscription Maritime for the port of La Ciotat in the second half of the nineteenth century. In this context, I will attempt to analyse the population characteristics of the city in the years from 1850 to 1914, by crossing and comparing the above data. At first, I will examine the increasing population trend, the immigration rising and its relation with the installation of a private shipping company in the shipyards of the city. Secondly, I will focus on the maritime labour market, by examining the rise or the decline of certain professions and specialisations. Besides, I will attempt to present the demographic changes and the career patterns of the maritime population of La Ciotat. This analysis may contribute to explain the factors that transformed the population of La Ciotat from a traditional maritime community into an industrialised shipbuilding centre during the industrial era.
Hydrodynamic obstruction to bubble expansion

description: We discuss a hydrodynamic obstruction to bubble wall acceleration during a cosmological first-order phase transition. The obstruction results from the heating of the plasma in the compression wave in front of the phase transition boundary. We provide a simple criterion for the occurrence of the obstruction at subsonic bubble wall velocity in terms of the critical temperature, the phase transition temperature, and the latent heat of the model under consideration. The criterion serves as a sufficient condition of subsonic bubble wall velocities as required by electroweak baryogenesis.

Open lithics : applying open source technologies to problems in lithic use wear experimentation and analysis
Creators: name: Waber, Nicholas Hans
Publisher: name: University of British Columbia
Year: 2020

description: This dissertation presents and examines open-source methods and technologies for recording and quantifying aspects of gesture in lithic use experiments, as well as measuring and mapping edge damage on stone tools. It has three interrelated parts. The first presents two tools for quantifying components of gesture in lithic experiments: 1) OpenHaft, an electronic handle designed to measure and record the load exerted on a stone tool’s edge during use, and 2) cumulative stroke distance (CSD), to calculate the total volume of tool use during a task. An experiment using CSD and OpenHaft shows both distance and load to be major factors affecting wear on stone tools. The second part applies a suite of GIS (geographic information system) tools to precisely quantify and map “macrowear”—the chipping and flaking damage from tool use. 3D digital photogrammetry was used to produce digital surface models (DSM) of experimental microblades, that were compared using custom scripts for QGIS, yielding a precise record of the volume and location of material wear. This allows researchers to observe edge attrition throughout a tool’s use life. This is relevant to archaeological questions around tool design, curation, maintenance, and discard. The third part examines the viability of the QGIS edge wear analysis method on archaeological lithics based on an adaptation of Kuhn’s (1990) geometric index of unifacial reduction flaking (GIURF). To apply GIURF to archaeological lithics, it is necessary to virtually reconstruct the artifact in its pristine state, which this study attempts to do. Based on the experiment, GIS-automated GIURF does not yet virtually reconstruct worn lithics with enough accuracy for precise wear quantification, but successful reconstruction of some sections of worn microblades indicates promise for further development. OpenHaft/CSD and the QGIS wear quantification modules help lithic analysts to perform experiments with robust control over gesture variables, better defining what is a “stroke”, and precisely measure the effects of stroke variation on stone tools. The project applies the same GIS-based wear measurement methods to archaeological samples and offers a roadmap for future development. These open source techniques and technologies provide researchers with an accessible toolkit for better lithic experimentation and objective macrowear quantification and analysis.

description: Here we report extensive ultrafast time-resolved reflectivity experiments on overdoped Bi$_{2}$Sr$_{2}$Ca$_{1-x}$Y$_x$Cu$_{2}$O$_{8+δ}$ single crystals (T$_C$=78 K) aimed to clarify the nature of the superconducting-to-normal-state photoinduced phase transition. The experimental data show the lack of the quasiparticles decay time divergence at the fluence required to induce this phase transition, in contrast to the thermally-driven phase transition observed at T$_C$ and at variance with recently reported photoinduced charge-density-wave and spin-density-wave to metal phase transitions. Our data demonstrate the non-thermal character of the superconducting-to-normal-state photoinduced phase transition. The data have been analyzed using an ad-hoc developed time-dependent Rothwarf-Taylor model, opening the question on the order of this non-equilibrium phase transition.

description: The present study investigated the possibility of using osmotically dehydrated Aloe vera gel as an additive to increase the nutritional quality and shelf life of stirred yoghurt. First, the extracted Aloe vera gel was osmotically dehydrated (OD) and pasteurized. Then it was added into yoghurt in three levels (5%, 7.5%, and 10%) and stirred. The best level of OD gel was selected through sensory evaluation and curd strength, and physiochemical properties, proximate composition, and microbial analysis were done to evaluate the quality of the final product for 35 days under 4°C. According to the results, the best OD Aloe gel percentage was 5% and all the physiochemical parameters were significantly (P˂0.05) higher than the controlled one at an acceptable level. Microbial analysis proved that the product has a strong antimicrobial activity towards yeast and mold growth and coliform increasing the shelf life of the product.

description: Gamma Ray Bursts (GRBs) are the most energetic sources in the universe and among the farthest known astrophysical sources. These features make them appealing candidates as standard candles for cosmological applications so that studying the physical mechanisms for the origin of the emission and correlations among their observable properties is an interesting task. We consider here the luminosity L*X - break time Ta* (hereafter LT) correlation and investigate whether there are systematics induced by selection effects or redshift dependent calibra- tion. We perform this analysis both for the full sample of 77 GRBs with known redshift and for the subsample of GRBs having canonical X-ray light curves, hereafter called U0095 sample. We do not find any systematic bias thus con- firming the existence of physical GRB subclasses revealed by tight correlations of their afterglow properties. Furthermore, we study the possibility of applying the LT correlation as a redshift estimator both for the full distribution and for the canonical lightcurves. The large uncertainties and the non negligible intrin- sic scatter make the results not so encouraging, but there are nevertheless some hints motivating a further analysis with an increased U0095 sample.

After illustrating basic properties of each braneworld model, we introduce the bulk/brane correspondence in the RS and KR braneworld models, adding supporting evidence for it. We then summarize the studies on braneworld black hole solutions, which consist of constructing exact or approximate solutions and investigating the phase diagram of solutions. In the study of phase diagram, we will also expound the implications of the bulk/brane correspondence to the braneworld black holes.

description:
The most at-risk population among women for human immunodeficiency virus (HIV) diagnosis in the United States are Black women, accounting for 61% of all new HIV cases. Pre-exposure prophylaxis (PrEP) is a safe and effective HIV prevention method for people at risk of HIV acquisition. Although disproportionately affected by HIV, Black women's knowledge, perceived benefits, and uptake of PrEP remain low. The socioecological model (SEM) may be useful for understanding why there is a low uptake of PrEP among Black women. The current study used the SEM to explore provider perspectives on the barriers and facilitators of PrEP uptake among Black women in Eastern Virginia. Semistructured interviews were conducted with a total sample of 15 community health care providers. Barriers of PrEP uptake at the societal (e.g., PrEP advertisements focus on gay men), community/organizational (e.g., time constraints in the workplace), interpersonal (e.g., perceived monogamy), and individual (e.g., unmet basic needs) levels were identified. Providers also identified facilitators of PrEP uptake at the societal (e.g., PrEP advertisements that target women), community/organizational (e.g., PrEP education), interpersonal (e.g., HIV-positive partner), and individual (e.g., PrEP awareness and perceived susceptibility to HIV) levels. These findings highlight unique barriers to accessing and taking PrEP for Black women in the United States, and potential factors that could facilitate PrEP use. Both barriers and facilitators may be important targets for interventions to improve PrEP uptake. Future research focused on improving PrEP uptake among Black women in the United States should consider multi-level interventions that target barriers and facilitators to reduce rates of HIV infections.

description: A new turbulent Taylor-Couette system consisting of two independently rotating cylinders has been constructed. The gap between the cylinders has a height of 0.927 m, an inner radius of 0.200 m, and a variable outer radius (from 0.279 to 0.220 m). The maximum angular rotation rates of the inner and outer cylinder are 20 and 10 Hz, respectively, resulting in Reynolds numbers up to 3.4 x 10^6 with water as working fluid. With this Taylor-Couette system, the parameter space (Re_i, Re_o, η) extends to (2.0 x 10^6, {\pm}1.4 x 10^6, 0.716-0.909). The system is equipped with bubble injectors, temperature control, skin-friction drag sensors, and several local sensors for studying turbulent single-phase and two-phase flows. Inner cylinder load cells detect skin-friction drag via torque measurements. The clear acrylic outer cylinder allows the dynamics of the liquid flow and the dispersed phase (bubbles, particles, fibers, etc.) inside the gap to be investigated with specialized local sensors and nonintrusive optical imaging techniques. The system allows study of both Taylor-Couette flow in a high-Reynolds-number regime, and the mechanisms behind skin-friction drag alterations due to bubble injection, polymer injection, and surface hydrophobicity and roughness.

description: We show a model of the slow expansion, in which the scale invariant spectrum of curvature perturbation is adiabatically induced by its increasing mode, by applying a generalized Galileon field. In this model, initially ε<< -1, which then is rapidly increasing, during this period the universe is slowly expanding. There is not the ghost instability, the perturbation theory is healthy. When ε\sim -1, the slow expansion phase ends, and the available energy of field can be released and the universe reheats. This scenario might be a viable design of the early universe.

description: Strongly anisotropic critical systems are considered in a $d$-dimensional film geometry. Such systems involve two (or more) distinct correlation lengths $ξ_β$ and $ξ_α$ that scale as nontrivial powers of each other, i.e.\ $ξ_α\simξ_β^θ$ with anisotropy index $θ\ne 1$. Thus two fundamental orientations, perpendicular ($\perp$) and parallel ($\|$), for which the surface normal is oriented along an $α$- and $β$-direction, respectively, must be distinguished. The confinement of critical fluctuations caused by the film's boundary planes is shown to induce effective forces $\mathcal{F}_C$ that decay as $\mathcal{F}_C\propto-(\partial/\partial L)Δ_{\perp,\|}\,L^{-ζ_{\perp,\|}}$ as the film thickness $L$ becomes large, where the proportionality constants involve nonuniversal amplitudes. The decay exponents $ζ_{\perp,\|}$ and the Casimir amplitudes $Δ_{\perp,\|}$ are universal but depend on the type of orientation. To corroborate these findings, $n$-vector models with an $m$-axial bulk Lifshitz point are investigated by means of RG methods below the upper critical dimension $d^*(m)=4+m/2$ under various boundary conditions (BC). The exponents $ζ_{\perp,\|}$ are determined, and explicit results to one- or two-loop order are presented for several Casimir amplitudes $Δ^{\mathrm{BC}}_{\perp,\|}$. The large-$n$ limits of the Casimir amplitudes $Δ_{\|}^{\mathrm{BC}}/n$ for periodic and Dirichlet BC are shown to be proportional to their critical-point analogues at dimension $d-m/2$. The limiting values $Δ^{\mathrm{PBC}}_{\|,\perp,\infty}=\lim_{n\to\infty}Δ_{\|,\perp}^{\mathrm{PBC}}/n$ are determined exactly for the uniaxial cases $(d,m)=(3,1)$ under periodic BC. Unlike $Δ^{\mathrm{PBC}}_{\|,\infty}$, $Δ^{\mathrm{PBC}}_{\perp,\infty}$ is positive, so that the corresponding Casimir force is repulsive.

description: We present a detailed theoretical study of the transfer of electronic excitation energy through the Fenna-Matthews-Olson (FMO) pigment-protein complex, using the new developed modified scaled hierarchical approach [Shi Q. et al, J Chem Phys 2009, 130, 084105]. We show that this approach is computationally more efficient than the original hierarchical approach. The modified approach reduces the truncation levels of the auxiliary density operators and the correlation function. We provide a systematic study of how the number of auxiliary density operators and the higher-order correlation functions affect the exciton dynamics. The time scales of the coherent beating are consistent with experimental observations. Furthermore, our theoretical results exhibit population beating at physiological temperature. Additionally, the method does not require a low-temperature correction to obtain the correct thermal equilibrium at long times.

A systematic investigation of thermal comfort compliance criteria
Creators: name: Li, Peixian
Publisher: name: University of British Columbia

description: Thermal comfort impacts occupant health and productivity and is responsible for a significant portion of the total building energy consumption. However, the compliance criteria in current standards to assess thermal comfort in a building’s operation phase are mostly based on a theoretical thermal comfort model (predicted mean vote—PMV) derived from laboratory studies and lack validation from data in real buildings. The research objective is to use field-based data to systematically investigate whether current point-in-time and long-term compliance criteria can reliably predict subjective evaluations of thermal environments. First, an extensive bibliometric analysis of 146 post-occupancy evaluation (POE) projects introduces the state-of-the-art and state-of-the-practice of approaches for field data collection. Then, an analysis of ASHRAE Global Thermal Comfort Database II demonstrates that tiered PMV classes are not appropriate for thermal comfort assessment at a point of time, and we proposed a new approach to derive acceptable temperature ranges as the point-in-time compliance criteria. The derived acceptable temperature ranges in real buildings using this new method are wider than the current standards mandate. Last, using continuous thermal measurements and occupant feedback in four air-conditioned office buildings in Sydney, an assessment of 23 existing and 36 new long-term thermal comfort indices (as the long-term compliance criteria) and their correlation with the occupants’ long-term thermal satisfaction found that the majority of existing indices, especially those based on PMV index, had a weak correlation with thermal satisfaction. The percentage of time outside specified temperature ranges was the best-performing index from the standards (r=-0.63). The newly proposed index based on the percentage of time that daily temperature range is greater than a threshold reported the strongest correlation (r=-0.8) with thermal satisfaction for the used dataset. The results suggest that occupants in real buildings can accept a wider temperature range at a point of time than expected, and their long-term thermal satisfaction with a space is dominated by the frequency and severity of temperature excursions outside an acceptable range and beyond a daily variability threshold. This research informs future amendments of the point-in-time and long-term compliance criteria in international standards to reduce energy consumption in building operations.

Solvable phase diagrams and ensemble inequivalence for two-dimensional and geophysical turbulent flows

description: Using explicit analytical computations, generic occurrence of inequivalence between two or more statistical ensembles is obtained for a large class of equilibrium states of two-dimensional and geophysical turbulent flows. The occurrence of statistical ensemble inequivalence is shown to be related to previously observed phase transitions in the equilibrium flow topology. We find in these turbulent flow equilibria, two mechanisms for the appearance of ensemble equivalences, that were not observed in any physical systems before. These mechanisms are associated respectively with second-order azeotropy (simultaneous appearance of two second-order phase transitions), and with bicritical points (bifurcation from a first-order to two second-order phase transition lines). The important roles of domain geometry, of topography, and of a screening length scale (the Rossby radius of deformation) are discussed. It is found that decreasing the screening length scale (making interactions more local) surprisingly widens the range of parameters associated with ensemble inequivalence. These results are then generalized to a larger class of models, and applied to a complete description of an academic model for inertial oceanic circulation, the Fofonoff flow.

K_1(1270)-K_1(1400) mixing and the fourth generation SM effects in B-->K_1l^+l^- decays

description: The implications of the fourth generation quarks in the B-->K_{1}(1270,1400)l^{+}l^{-} with l=mu, tau decays are studied, where the mass eigenstates K_{1}(1270) and K_{1}(1400) are the mixture of ^{1}{P}_{1} and ^{3}{P}_{1} states with the mixing angle θ_{K}. In this context, we have studied various observables like branching ratio (BR), forward backward asymmetry (A_{FB}) and longitudinal and transverse helicity fractions (f_{L,T}) of K_{1} meson in B-->K_{1}l^{+}l^{-} decays. To study these observables, we have used the Light Cone QCD sum rules form factors and set the mixing angle θ_{K}=-34^{o}. It is noticed that the BR is suppressed for K_{1}(1400) as a final state meson compared to that of K_{1}(1270). Same is the case when the final state leptons are tauons rather than muons. In both the situations all the above mentioned observables are quite sensitive to the fourth generation effects. Hence the measurements of these observables at LHC, for the above mentioned processes can serve as a good tool to investigate the indirect searches for the existence of fourth generation quarks.

description: In this paper we study the emergence of coherence in collective motion described by a system of interacting motiles endowed with an inner, adaptative, steering mechanism. By means of a nonlinear parametric coupling, the system elements are able to swing along the route to chaos. Thereby, each motile can display different types of behavior, i.e. from ordered to fully erratic motion, accordingly with its surrounding conditions. The appearance of patterns of collective motion is shown to be related to the emergence of interparticle synchronization and the degree of coherence of motion is quantified by means of a graph representation. The effects related to the density of particles and to interparticle distances are explored. It is shown that the higher degrees of coherence and group cohesion are attained when the system elements display a combination of ordered and chaotic behaviors, which emerges from a collective self-organization process.

description: In Ruderman & Sutherland (RS75) model, the normal neutron stars as pulsars bear a severe problem, namely the binding energy problem that both ions (e.g., ${}_{26}^{56}$Fe) and electrons on normal neutron star surface can be pulled out freely by the unipolar generator induced electric field so that sparking on polar cap can hardly occur. {\bf This problem could be solved within the Partially Screened Gap (PSG) model in the regime of neutron stars}. However, in this paper we extensively study this problem in a bare strange quark star (BSS) model. We find that the huge potential barrier built by the electric field in the vacuum gap above polar cap could usually prevent electrons from streaming into the magnetosphere unless the electric potential of a pulsar is sufficiently lower than that at infinite interstellar medium. Other processes, such as the diffusion and thermionic emission of electrons have also been included here. Our conclusions are as follows: both positive and negative particles on a BSS's surface would be bound strongly enough to form a vacuum gap above its polar cap as long as the BSS is not charged (or not highly negative charged), and multi-accelerators could occur in a BSS's magnetosphere. Our results would be helpful to distinguish normal neutron stars and bare quark stars through pulsar's magnetospheric activities.
