description: Beginning with Bekenstein, many authors have considered a uniformly spaced discrete quantum spectrum for black hole horizon area. It is also believed that the huge degeneracy of these area levels corresponds to the notion of black hole entropy. Starting from these two assumptions we here infer the algebra of a Schwarzschild black hole's observables. This algebra then serves as motivation for introducing in the system's Hamiltonian an interaction term. The interaction contains the horizon area operator, which is a number operator, and its canonical conjugate, the phase operator. The Hawking radiation from a Schwarzschild black hole is seen to be a consequence of an area-phase interaction. Using this interaction we have reproduced the semi-classical result for the Hawking radiation power. Furthermore, we show that the initial state of the black hole determines the nature of its development. Thus, a state which is an area eigenstate describes a static eternal black hole, but a coherent state describes a radiating black hole. Hence, it is the observer's initial knowledge or uncertainty about the horizon area which determines the evolution.

description: We investigate numerically complex dynamical systems where a fixed point is surrounded by a disk or ball of quasiperiodic orbits, where there is a change of variables (or conjugacy) that converts the system into a linear map. We compute this "linearization" (or conjugacy) from knowledge of a single quasiperiodic trajectory. In our computations of rotation rates of the almost periodic orbits and Fourier coefficients of the conjugacy, we only use knowledge of a trajectory, and we do not assume knowledge of the explicit form of a dynamical system. This problem is called the Babylonian Problem: determining the characteristics of a quasiperiodic set from a trajectory. Our computation of rotation rates and Fourier coefficients depends on the very high speed of our computational method "the weighted Birkhoff average".

description: (abridged) Even if the HARPS spectrograph has been operational for more than 15 years and it provides among the most precise Doppler measurements, improvements are still possible. One known problem, for instance, is the non-fully regular block-stitching of the CCDs, which introduces, in some cases, one-year period parasitic signals in the measured radial velocity. The aim is to improve the wavelength calibration of HARPS to push further its planet-detection capabilities. The properties of the CCD stitching-induced pixel-size anomalies are determined with LED flat-field frames, and then a physical, gap-corrected map of the CCDs is used for the fitting model of the spectral orders. We also use a new thorium line list, based on much higher-accuracy measurements than the one used up to now. We derive new wavelength solutions for the 15 years of HARPS data, both before and after the 2015 fibre upgrade. We demonstrate that we correct the gap anomalies by computing the wavelength solutions of laser frequency comb exposures, both with and without taking the gap correction into account. By comparing the rms of the most stable stars of the HARPS sample, we show that we globally decrease the radial velocity dispersion of the data, especially for the data acquired after the change of fibres. Finally, the comparative analysis of several individual systems shows that we manage to attenuate the periodogram power at one year in most cases. The analysis of the RVs derived from individual stellar lines also shows that we correct the stitching-induced RV variation. This improved calibration of the HARPS spectrograph allows to go deeper in the search for low-amplitude radial-velocity signals. It will be further improved by combining the thorium calibration spectra with laser frequency comb and Fabry-Perot calibration spectra, and not only for HARPS but notably also for HARPS-N and ESPRESSO.

description: Approaching a quantum critical point (QCP) has been an effective route to stabilize superconductivity. While the role of magnetic QCPs has been extensively discussed, similar exploration of a structural QCP is scarce due to the lack of suitable systems with a continuous structural transition that can be conveniently tuned to 0~K. Using inelastic X-ray scattering, we examine the phonon spectrum of the nonmagnetic quasi-skutterudite (Ca$_{x}$Sr$_{1-x}$)$_3$Rh$_4$Sn$_{13}$, which represents a precious system to explore the interplay between structural instabilities and superconductivity by tuning the Ca concentration $x$. We unambiguously detect the softening of phonon modes around the M point on cooling towards the structural transition. Intriguingly, at $x=0.85$, the soft mode energy squared at the M point extrapolates to zero at $(-5.7 \pm 7.7)$~K, providing the first compelling microscopic evidence of a structural QCP in (Ca$_{x}$Sr$_{1-x}$)$_3$Rh$_4$Sn$_{13}$. The enhanced phonon density-of-states at low energy provides the essential ingredient for realizing strong-coupling superconductivity near the structural QCP.

subject: Philosophy and religious studies

description: The rapid urbanization has resulted in several problems for Pakistan's low-income people, with housing shortage being the most irritating problem. There is a lack of quality living environment for low-income people. Secondly, our urban environment is lacking Islamic planning and architectural principles. Despite a rich architectural and planning history, we still follow Western traditions. These disturbing issues have been addressed in this research work. This research aims to propose a strategy for low-income housing that suits the social and cultural values of Lahore, and it will reflect traditional Islamic planning and environmental principles. Also, suitable indicators of housing sustainability and affordability in Lahore are to be acquired. The primary sources studied included Christopher Alexander, Ibn Khaldun (1332-1406), N. John Habraken, Charles Correa, Amos Rapoport, Kevin Lynch, Mohammed Arkoun, Hassan Fathy and The Aga Khan Archives. The other literature review topics included low-income people, Islamic principles for planning and architecture, and sustainable and affordable housing indicators. In addition to that, four successful housing projects were also critically analyzed based on their strengths and weaknesses. Data collected from 45 officials regarding the significance of housing sustainability and affordability indicators was analyzed through descriptive statistics or inferential statistics. Another survey was also conducted and analyzed for 53 low-income earners on their social and cultural needs. Based on the data analysis, a housing scheme and house plans were designed for 583 households in Lahore. The housing designs were based on different Islamic planning, sustainability, and affordability principles. Moreover, this study's outcome can be a platform for researchers to pursue further research works.

CATEGORIZING BENEFITS AND ANALYZING SUCCESS FACTORS IN INTERCOLLEGIATE ATHLETIC FUNDRAISING: AN FBS SCHOOL STUDY
Creators: name: Rapisarda, Luke
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2024

description: Intercollegiate development leaders are facing increasing challenges to raising money. As a result, it becomes increasingly important for fundraisers to overcome those challenges to continue to provide scholarship support for the university. No prior research exists on how experiential benefits have a relationship with revenue. The present study examines how benefits on the annual fund benefits charts could be leveraged to increase fundraising by first collecting all the experiential benefits and having them rated as experiential as not by experts. Schools were categorized into overperforming and underperforming based on a predictive model. A group comparison examined these two categories and their number of experiential benefits. The results of the study suggest that schools that overperformed against the predictive model average 4.57 experiential benefits on their benefits chart, while those that underperformed average 3.81. The results of this study warrant future research.

description: The cubic nonlinear Schrödinger equation with repulsive nonlinearity and an elliptic function potential models a quasi-one-dimensional repulsive dilute gas Bose-Einstein condensate trapped in a standing light wave. New families of stationary solutions are presented. Some of these solutions have neither an analog in the linear Schrödinger equation nor in the integrable nonlinear Schrödinger equation. Their stability is examined using analytic and numerical methods. All trivial-phase stable solutions are deformations of the ground state of the linear Schrödinger equation. Our results show that a large number of condensed atoms is sufficient to form a stable, periodic condensate. Physically, this implies stability of states near the Thomas-Fermi limit.

description: We present a microscopic examination for the itinerant-localized duality model which has been proposed to understand anomalous properties of strongly correlated systems like the heavy fermions by Kuramoto and Miyake, and also useful to describe the anomalous properties of the high-Tc cupurates. We show that the thermodynamic potential of the strongly interacting Hubbard model can be rearranged in the form of duality model on the basis of renormalized perturbation expansion of the Luttinger-Ward functional if the one-particle spectral weight exhibits triple peak structure. We also examine the incoherent degrees of freedom described as a ``localized spin'' and show on the basis of the pertubation expansion that there exists commensurate superexchange-type interaction among the ``localized spins''.

description: The Australian National University (ANU) Centre for Indigenous Policy Research (formerly the Centre for Aboriginal Economic Policy Research (CAEPR)) was commissioned by Aboriginal Affairs New South Wales (AANSW) to conduct the second phase of the co-designed evaluation of Local Decision Making (LDM), an initiative under the OCHRE (Opportunity, Choice, Healing, Responsibility, Empowerment) plan for Aboriginal affairs in New South Wales (NSW). The Stage Two Evaluation is an outcome evaluation, investigating if and how the OCHRE LDM initiative is achieving ‘what it set out to do’ across five LDM sites. This co-designed, participatory evaluation has taken place over four years from 2020–2023 across five NSW regions, represented by five Aboriginal Regional Alliances/Assemblies, and at a state level with the NSW Coalition of Aboriginal Regional Alliances (NCARA). The evaluation is guided by a strengths-based methodology that weaves together First Nations knowledge with that of the public sector and academia. The OCHRE LDM Stage Two Evaluation Synthesis Report is one of ten reports produced by CIPR researchers under this stage of the evaluation. CIPR’s evaluation of the LDM Accord Negotiation process produced three site-specific LDM Accord Negotiation reports and a report synthesising the findings of those evaluations. CIPR’s evaluation of LDM as a whole has produced this synthesis report, three site-specific evaluation reports, a state-wide evaluation report, and preliminary findings report. CIPR evaluated the operation of LDM across the regions of three Aboriginal Regional Alliances/Assemblies -– Murdi Paaki Regional Assembly, Three Rivers Regional Assembly, and Illawarra-Wingecarribee Aboriginal Alliance Corporation. CIPR has also evaluated the NSW Coalition of Aboriginal Regional Alliance (NCARA)-State Accord and three LDM Accord negotiation processes for the Barang Regional Alliance Accord, the Riverina Murray Regional Assembly Accord, and the Murdi Paaki Regional Assembly Accord II. The OCHRE LDM Stage 2 Evaluation Synthesis Report consolidates key recommendations of the OCHRE LDM Stage Two evaluations, to help guide NSW government agencies in developing a structured programme of action to improve their performance so that the LDM initiative operates as intended.

Using this coordinate transformation it is possible to express BS quantities in terms of NP quantities, and to show that if the Outgoing Radiation Condition is not satisfied then the spacetime will not decay in the way prescribed by the Peeling theorem.

description: We report stable orthogonally polarised domains in high-density polariton solitons propagating in a semiconductor microcavity wire. This effect arises from spin dependent polariton-polariton interactions and pump-induced imbalance of polariton spin populations. The interactions result in an effective magnetic field acting on polariton spin across the soliton profile, leading to the formation of polarisation domains. Our experimental findings are in excellent agreement with theoretical modelling taking into account these effects.

description: We study the persistent currents induced by both the Aharonov-Bohm and Aharonov-Casher effects in a one-dimensional mesoscopic ring coupled to a side-branch quantum dot at Kondo resonance. For privileged values of the Aharonov-Bohm-Casher fluxes, the problem can be mapped onto an integrable model, exactly solvable by a Bethe ansatz. In the case of a pure magnetic Aharonov-Bohm flux, we find that the presence of the quantum dot has no effect on the persistent current. In contrast, the Kondo resonance interferes with the spin-dependent Aharonov-Casher effect to induce a current which, in the strong-coupling limit, is independent of the number of electrons in the ring.

description: The Gunn effect consists of time-periodic oscillations of the current flowing through an external purely resistive circuit mediated by solitary wave dynamics of the electric field on an attached appropriate semiconductor. By means of a new asymptotic analysis, it is argued that Gunn-like behavior occurs in specific classes of model equations. As an illustration, an example related to the constrained Cahn-Allen equation is analyzed.

description: The quest for wave channeling and manipulation has driven a strong research effort on topological and architected materials, capable of propagating localized electromagnetical or mechanical signals. With reference to an elastic structural grid, which elements can sustain both axial and flexural deformations, it is shown that material interfaces can be created with structural properties tuned by prestress states to achieve total reflection, negative refraction, and strongly localized signal channeling. The achievement of a flat lens and topologically localized modes is demonstrated and tunability of the system allows these properties to hold for a broad range of wavelengths. An ingredient to obtain these effects is the use, suggested here and never attempted before, of concentrated pulsating moments. The important aspect of the proposed method is that states of prestress can be easily removed or changed to tune with continuity the propagational characteristics of the medium, so that a new use of vibration channeling and manipulation is envisaged for elastic materials.

description: With the help of families of density contrast indicators, we study the tendency of gravitational systems to become increasingly lumpy with time. Depending upon their domain of definition, these indicators could be local or global. We make a comparative study of these indicators in the context of inhomogeneous cosmological models of Lemaitre--Tolman and Szekeres. In particular, we look at the temporal asymptotic behaviour of these indicators and ask under what conditions, and for which class of models, they evolve monotonically in time. We find that for the case of ever-expanding models, there is a larger class of indicators that grow monotonically with time, whereas the corresponding class for the recollapsing models is more restricted. Nevertheless, in the absence of decaying modes, indicators exist which grow monotonically with time for both ever-expanding and recollapsing models simultaneously. On the other hand, no such indicators may found which grow monotonically if the decaying modes are allowed to exist. We also find the conditions for these indicators to be non-divergent at the initial singularity in both models. Our results can be of potential relevance for understanding structure formation in inhomogeneous settings and in debates regarding gravitational entropy and arrow of time. In particular, the spatial dependence of turning points in inhomogeneous cosmologies may result in multiple density contrast arrows in recollapsing models over certain epochs. We also find that different notions of asymptotic homogenisation may be deduced, depending upon the density contrast indicators used.

description: Robotic systems have been evolving since decades and touching almost all aspects of life, either for leisure or critical applications. Most of traditional robotic systems operate in well-defined environments utilizing pre-configured on-board processing units. However, modern and foreseen robotic applications ask for complex processing requirements that exceed the limits of on-board computing power. Cloud computing and the related technologies have high potential to overcome on-board hardware restrictions and can improve the performance efficiency. This research highlights the advancements in robotic systems with focus on cloud robotics as an emerging trend. There exists an extensive amount of effort to leverage the potentials of robotic systems and to handle arising shortcomings. Moreover, there are promising insights for future breed of intelligent, flexible, and autonomous robotic systems in the Internet of Things era.

description: The status of experimental tests of general relativity and of theoretical frameworks for analysing them are reviewed. Einstein's equivalence principle (EEP) is well supported by experiments such as the Eötvös experiment, tests of special relativity, and the gravitational redshift experiment. Future tests of EEP will search for new interactions arising from unification or quantum gravity. Tests of general relativity have reached high precision, including the light deflection, the Shapiro time delay, the perihelion advance of Mercury, and the Nordtvedt effect in lunar motion. Gravitational wave damping has been detected to half a percent using the binary pulsar, and new binary pulsar systems promise further improvements. When direct observation of gravitational radiation from astrophysical sources begins, new tests of general relativity will be possible.

While our experimental results using geometric rules and transformations demonstrate the performance of our methods on an image translation task with industry applications in art, design and animation, we also propose the use of rules on partial data sets as a generalizable small data strategy, potentially applicable across data types and domains.
Isotropic-Nematic Transition and Demixing Behaviour in Binary Mixtures of Hard Spheres and Hard Spherocylinders Confined in a Disordered Porous Medium: Scaled Particle Theory

description: We develop the scaled particle theory to describe the thermodynamic properties and orientation ordering of a binary mixture of hard spheres (HS) and hard spherocylinders (HSC) confined in a disordered porous medium. Using this theory the analytical expressions of the free energy, the pressure and the chemical potentials of HS and HSC have been derived. The improvement of obtained results is considered by introducing the Carnahan-Starling-like and Parsons-Lee-like corrections. Phase diagrams for the isotropic-nematic transition are calculated from the bifurcation analysis of the integral equation for the orientation singlet distribution function and from the conditions of thermodynamic equilibrium. Both the approaches correctly predict the isotropic-nematic transition at low concentrations of hard spheres. However, the thermodynamic approach provides more accurate results and is able to describe the demixing phenomena in the isotropic and nematic phases. The effects of porous medium on the isotropic-nematic phase transition and demixing behaviour in a binary HS/HSC mixture are discussed.

description: A traversable wormhole solution of general scalar-tensor field equations is presented. We have shown, after a numerical analysis for the behavior of the scalar field of Brans-Dicke theory, that the solution is completely singularity--free. Furthermore, the analysis of more general scalar field dependent coupling constants indicates that the gravitational memory phenomenon may play an important role in the fate of natural wormholes.

description: A consistent description of low-energy charge and spin responses of the insulating Sr_2CuO_2Cl_2 lamellar system is found in the framework of a one-band Hubbard model which besides $U$ includes hoppings up to 3^{rd} nearest-neighbors. By combining mean-field calculations, exact diagonalization (ED) results, and Quantum Monte Carlo simulations (QMC), we analyze both charge and spin degrees of freedom responses as observed by optical conductivity, ARPES, Raman and inelastic neutron scattering experiments. Within this effective model, long-range hopping processes flatten the quasiparticle band around $(0,π)$. We calculate also the non-resonant A_{1g} and B_{1g} Raman profiles and show that the latter is composed by two main features, which are attributed to 2- and 4-magnon scattering.

description: This paper discusses some aspects of the application of Artificial Intelligence to fraud detection in real-time income verification systems of the FinTech industry. Stressing the advanced level of Computer Vision-based Optical Character Recognition, this study demonstrates how financial data extraction and analysis have been accurately performed from documents such as bank statements and pay slips by AI algorithms, while detecting anomalies and discrepancies indicative of fraud. The proposed framework therefore contributes to enhancing efficiency in fraud detection with lesser false positives.This will integrate AI-driven anomaly detection models, including supervised and unsupervised machine learning techniques, to provide fraud identification in real time with unparalleled precision and responsiveness to novel fraudulent patterns. The outcome reveals that this would optimize the transaction security and scalability, solving a very critical limitation of the classic systems. This study showed how AI is set to transform a more robust, efficient, and trustworthy FinTech income verification ecosystem.
$1/f^α$ noise from self-organized critical models with uniform driving

description: Using the well-known Olami-Feder-Christensen model as our paradigm, we show how to modify uniform driven self-organized critical models to generate $1/f^α$ noise. Our model can reproduce all the main features of $1/f^α$ noise: (1) $α$ is close to one and does not depend on the dimension of the system. (2) The $1/f^α$ behavior is found for very low frequencies. (3) The spatial correlations do not obey a power law. That proves that spatially extended systems based on activation-deactivation processes do not have to be point-driven to produce $1/f^α$ noise. The essential ingredient is a local memory of the activation-deactivation process.

description: In this paper, we consider the rotating charged Gödel black hole and study the effect of the higher order corrections of the entropy on the thermodynamics and statistics quantities of the Kerr-Newman-Gödel black hole. The leading order correction is logarithmic while higher-order terms are proportional to the inverse of the area of the black hole. We obtain modified thermodynamics and statistics and find that correction terms are important in the stability of the black hole.

PROBING SELECTIVITY FOR PEPTIDOMIMETIC INHIBITORS OF PHD DOMAINS
Creators: name: Schomburg, Noah Keith
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2024

description: The work herein investigates the selectivity of peptidomimetic inhibitors targeting PHD domains, a class of Kme3 reader proteins. While the preference of Kme3 over tBuNle in binding is well-established for most Kme3 reader proteins, recent findings uncovered several proteins that exhibit a preference for tBuNle, most of which were PHD domains. Structural analysis highlighted a potential avenue for achieving selectivity via threonine 3 (T3) substitutions on peptide mimics of the histone 3 (H3) tail. However, our fluorescence polarization binding studies revealed that canonical bulky and hydrophobic substitutions at T3 failed to confer selectivity for ING3 PHD over other studied proteins. Our findings underscore the complexity of achieving selectivity within the PHD domain family.

description: We present a general formulation of the time-dependent initial value problem for a quantum scalar field of arbitrary mass and curvature coupling in a FRW cosmological model. We introduce an adiabatic number basis which has the virtue that the divergent parts of the quantum expectation value of the energy-momentum tensor are isolated in the vacuum piece of , and may be removed using adiabatic subtraction. The resulting renormalized is conserved, independent of the cutoff, and has a physically transparent, quasiclassical form in terms of the average number of created adiabatic `particles'. By analyzing the evolution of the adiabatic particle number in de Sitter spacetime we exhibit the time structure of the particle creation process, which can be understood in terms of the time at which different momentum scales enter the horizon. A numerical scheme to compute as a function of time with arbitrary adiabatic initial states (not necessarily de Sitter invariant) is described. For minimally coupled, massless fields, at late times the renormalized goes asymptotically to the de Sitter invariant state previously found by Allen and Folacci, and not to the zero mass limit of the Bunch-Davies vacuum. If the mass m and the curvature coupling xi differ from zero, but satisfy m^2+xi R=0, the energy density and pressure of the scalar field grow linearly in cosmic time demonstrating that, at least in this case, backreaction effects become significant and cannot be neglected in de Sitter spacetime.

The Perils of Detecting Measurement Faults in Environmental Monitoring Networks

description: Scientists deploy environmental monitoring net-works to discover previously unobservable phenomena and quantify subtle spatial and temporal differences in the physical quantities they measure. Our experience, shared by others, has shown that measurements gathered by such networks are perturbed by sensor faults. In response, multiple fault detection techniques have been proposed in the literature. However, in this paper we argue that these techniques may misclassify events (e.g. rain events for soil moisture measurements) as faults, potentially discarding the most interesting measurements. We support this argument by applying two commonly used fault detection techniques on data collected from a soil monitoring network. Our results show that in this case, up to 45% of the event measurements are misclassified as faults. Furthermore, tuning the fault detection algorithms to avoid event misclassification, causes them to miss the majority of actual faults. In addition to exposing the tension between fault and event detection, our findings motivate the need to develop novel fault detection mechanisms which incorporate knowledge of the underlying events and are customized to the sensing modality they monitor.

Adapting Adaptive Preferences to Animals
Creators: name: d'Leeuwen, Myraeka
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2024

description: Humans exert a considerable amount of control, sometimes even oppressive control, over domestic animals. Sometimes, as a result of this influence, domestic animals exhibit preferences for practices that appear intuitively restrictive or cruel. I argue that these preferences can be described as adaptive preferences. Adaptive preferences are theorized in feminist philosophy to describe phenomena whereby oppressed people reinforce elements of their own oppression. I argue that an account of adaptive preferences that does not rely upon autonomy, but instead explains adaptive preferences as preferences in opposition to an agent’s basic welfare and caused by oppression, explains this phenomenon in domestic animals as well. As a result of some preferences of domestic animals being adaptive, the purported approval of oppressive systems by animals should not be taken as evidence that these systems are not harmful, and it is sometimes acceptable to override an animal’s choices when we would ordinarily respect them.

description: The P300 Brain-Computer Interface (BCI) is a well-established communication channel for severely disabled people. The P300 event-related potential is mostly characterized by its amplitude or its area, which correlate with the spelling accuracy of the P300 speller. Here, we introduce a novel approach for estimating the efficiency of this BCI by considering the P300 signal-to-noise ratio (SNR), a parameter that estimates the spatial and temporal noise levels and has a significantly stronger correlation with spelling accuracy. Furthermore, we suggest a Gaussian noise model, which utilizes the P300 event-related potential SNR to predict spelling accuracy under various conditions for LDA-based classification. We demonstrate the utility of this analysis using real data and discuss its potential applications, such as speeding up the process of electrode selection.
Curvature invariants in type-III spacetimes

description: The results of paper [1] are generalized for vacuum type-III solutions with, in general, a non-vanishing cosmological constant Lambda. It is shown that all curvature invariants containing derivatives of the Weyl tensor vanish if a type-III spacetime admits a non-expanding and non-twisting null geodesic congruence. A non-vanishing curvature invariant containing first derivatives of the Weyl tensor is found in the case of type-III spacetime with expansion or twist.
