The findings indicate significant improvements in key performance indicators, including a 30% enhancement in decision-making speed and a 25% increase in resource utilization efficiency, compared to conventional measurement methods.
The study builds on established theoretical foundations and incorporates recent advancements in AI and big data analytics. By integrating AI-enhanced metrics with traditional administrative indicators, the model confirms the viability of digital performance measurement while offering a robust tool for managerial decision-making in dynamic environments. The survey results provide compelling empirical evidence that AI-driven analytics can uncover latent performance patterns and deliver actionable insights, enabling organizations to optimize resource allocation and improve overall operational efficiency.
Furthermore, this research highlights the importance of developing adaptable measurement tools that keep pace with the evolving digital landscape. The confirmatory results underscore the potential of AI to bridge the gap between conventional performance evaluation systems and the demands of modern digital administration. Overall, the study presents a validated framework that enhances the precision and depth of performance assessments, setting a benchmark for future innovations in digital management.

description: Motion analysis is used in computer vision to understand the behaviour of moving objects in sequences of images. Optimising the interpretation of dynamic biological systems requires accurate and precise motion tracking as well as efficient representations of high-dimensional motion trajectories so that these can be used for prediction tasks. Here we use image sequences of the heart, acquired using cardiac magnetic resonance imaging, to create time-resolved three-dimensional segmentations using a fully convolutional network trained on anatomical shape priors. This dense motion model formed the input to a supervised denoising autoencoder (4Dsurvival), which is a hybrid network consisting of an autoencoder that learns a task-specific latent code representation trained on observed outcome data, yielding a latent representation optimised for survival prediction. To handle right-censored survival outcomes, our network used a Cox partial likelihood loss function. In a study of 302 patients the predictive accuracy (quantified by Harrell's C-index) was significantly higher (p < .0001) for our model C=0.73 (95$\%$ CI: 0.68 - 0.78) than the human benchmark of C=0.59 (95$\%$ CI: 0.53 - 0.65). This work demonstrates how a complex computer vision task using high-dimensional medical image data can efficiently predict human survival.
Research on Power Quality Improvement in Distribution System with Induction Motor Load Using Fuzzy Logic Controlled UPQC

description: This paper presents the operation of unified power quality conditioner (UPQC) as a universal active power conditioning device to mitigate both current as well as voltage distortions at a distribution end of power system network. The UPQC is designed by combining a series active power filter (DVR) and shunt active power filter (DSTATCOM) which shares a common DC link capacitor. Series compensator which is meant for voltage restoring is controlled by a fuzzy logic controller. Shunt compensator’s operation is controlled by extracting d axis and q axis current from load current and DC link voltage is maintained through a fuzzy logic controller. The performance of UPQC mainly depends upon how quickly and accurately compensation signals are derived. The steady state and dynamic operation of control circuit in different load current and/or utility voltages conditions is studied through simulation results. The presented method has acceptable dynamic response with a very simple configuration of control circuit. The designed UPQC is tested with an induction motor load. It is able to mitigate voltage sag/ swell, reactive power compensation, voltage fluctuations, harmonic elimination etc. under these load conditions. UPQC mitigates the voltage and current based distortion simultaneously as well as independently. The proposed system and controller is validated using MATLAB/simulink. The simulation results express a low THD and a perfect compensation.

description: Using approximate techniques we study the final moments of the collision of two (individually non-spinnning) black holes which inspiral into each other. The approximation is based on treating the whole space-time as a single distorted black hole. We obtain estimates for the radiated energy, angular momentum and waveforms for the gravitational waves produced in such a collision. The results can be of interest for analyzing the data that will be forthcoming from gravitational wave interferometric detectors, like the LIGO, GEO, LISA, VIRGO and TAMA projects.

Spin evolution and feedback of supermassive black holes in cosmological simulations

description: It is well established that the properties of supermassive black holes and their host galaxies are correlated through scaling relations. While hydrodynamical cosmological simulations have begun to account for the co-evolution of BHs and galaxies, they typically have neglected the BH spin, even though it may play an important role in modulating the growth and feedback of BHs. Here we introduce a new sub-grid model for the BH spin evolution in the moving-mesh code {\small AREPO} in order to improve the physical faithfulness of the BH modelling in galaxy formation simulations. We account for several different channels of spin evolution, in particular gas accretion through a Shakura-Sunyaev $α$-disc, chaotic accretion, and BH mergers. For BH feedback, we extend the IllustrisTNG model, which considers two different BH feedback modes, a thermal quasar mode for high accretion states and a kinetic mode for low Eddington ratios, with a self-consistent accounting of spin-dependent radiative efficiencies and thus feedback strength. We find that BHs with mass $M_{\rm{bh}}\lesssim 10^{8}\, {\rm M}_\odot$ reach high spin values as they typically evolve in the coherent gas accretion regime. On the other hand, BHs with mass $M_{\rm{bh}}\gtrsim 10^{8}\, {\rm M}_\odot$ have lower spins as BH mergers become more frequent, and their accretion discs fragment due to self-gravity, inducing chaotic accretion. We also explore the hypothesis that the transition between the quasar and kinetic feedback modes is mediated by the accretion mode of the BH disc itself, i.e.~the kinetic feedback mode is activated when the disc enters the self-gravity regime. We find excellent agreement between the galaxy and BH populations for this approach and the fiducial TNG model with no spin evolution. Furthermore, our new approach alleviates a tension in the galaxy morphology -- colour relation of the original TNG model.

description: We obtain the complete theory of Newton-Cartan gravity in a curved spacetime by considering the large $c$ limit of the vielbein formulation of General Relativity. Milne boosts originate from local Lorentzian transformations, and the special cases of torsionless and twistless torsional geometries are explained in the context of the larger locally Lorentzian theory. We write the action for Newton-Cartan fields in the first order Palatini formalism, and the large $c$ limit of the Einstein equations. Finally, we obtain the generalised Eisenhart-Duval lift of the metric that plays an important role in non-relativistic holography.

description: Among the sports fans beliefs about "hot hands" and "winning streaks" are widely spread, while the scientific debate about these effects is still ongoing. Recently in a paper by P. Ferreira [Physica A 500: 92-96] detrended fluctuation analysis was applied to the NBA teams' win records. It was shown that 28 considered NBA teams exhibit persistence in the win record time series. In this paper we take the same data set and compare the obtained results against various random models. We find that the empirical results are consistent with the results obtained from various simple random models.

Magnetic Properties and Flow Angle of the Inverse Evershed Flow at Its Downflow Points

description: We determined the direction and strength of the photospheric and lower chromospheric magnetic field in the umbra and penumbra of a sunspot from inversions of spectropolarimetric observations of photospheric lines at 617\,nm and 1565\,nm, and the chromospheric \ion{Ca}{ii} IR line at 854\,nm, respectively. We compare the magnetic field vector with the direction of 75 flow channels that harbor the chromospheric inverse Evershed effect (IEF) near their downflow points (DFPs) in the sunspot's penumbra. The azimuth and inclination of the IEF channels to the line of sight (LOS) were derived from spatial maps of the LOS velocity and line-core intensity of the \ion{Ca}{ii} IR line and a thermal inversion of the \ion{Ca}{ii} IR spectra to obtain temperature cubes. We find that the flow direction of the IEF near the DFPs is aligned with the photospheric magnetic field to within about $\pm$\,15\,deg. The IEF flow fibrils make an angle of 30--90\,deg to the local vertical with an average value of about 65\,deg. The average field strength at the DFPs is about 1.3\,kG. Our findings suggest that the IEF in the lower chromosphere is a field-aligned siphon flow, where the larger field strength at the inner footpoints together with the lower temperature in the penumbra causes the necessary gas pressure difference relative to the outer footpoints in the hotter quiet Sun with lower magnetic field strength. The IEF connects to magnetic field lines that are not horizontal like for the regular photospheric Evershed flow, but which continue upwards into the chromosphere indicating an "uncombed" penumbral structure.

description: Electromagnetic wave scattering off density inhomogeneities in the solar corona is an important process which determines both the apparent source size and the time profile of radio bursts observed at 1 AU. Here we model the scattering process using a Fokker-Planck equation and apply this formalism to several regimes of interest. In the first regime the density fluctuations are considered quasi-static and diffusion in wavevector space is dominated by angular diffusion on the surface of a constant energy sphere. In the small-angle ("pencil beam") approximation, this diffusion further occurs over a small solid angle in wavevector space. The second regime corresponds to a much later time, by which scattering has rendered the photon distribution near-isotropic resulting in a spatial diffusion of the radiation. The third regime involves time-dependent fluctuations and, therefore, Fermi acceleration of photons. Combined, these results provide a comprehensive theoretical framework within which to understand several important features of propagation of radio burst waves in the solar corona: emitted photons are accelerated in a relatively small inner region and then diffuse outwards to larger distances. En route, angular diffusion results both in source sizes which are substantially larger than the intrinsic source, and in observed intensity-versus-time profiles that are asymmetric, with a sharp rise and an exponential decay. Both of these features are consistent with observations of solar radio bursts.

description: Cylindrical vector beams (CVBs) have a wide range of applications owing to their particular polarization characteristics and optical field distributions. For the first time, an azimuthally polarized fiber laser without any polarization controller is proposed and demonstrated experimentally. The scheme is based on a self-designed ring-core fiber and transverse mode filter (TMF). The ring-core fiber can break the degeneracy of LP11 modes and make the TE01 mode propagate stably in the fiber laser. The TMF, which made from the ring-core fiber by depositing a layer of Aluminum on the cladding surface, can effectively suppress the modes other than TE01 mode. The fiber laser can stably operate at TE01 mode with a narrow 30dB linewidth of 0.18nm, which indicates the laser is polarization-maintained. This study opens a new avenue toward the true application of CVBs fiber lasers.

description: We indicate that Coulombic systems could correspond to Wilson effective Hamiltonians similar to that of the ordinary (nonionic) fluids but with a negative $ϕ^4$-coefficient. In that case, solving the ``exact'' renormalization group equation in the local potential approximation, we show that close initial Hamiltonians may lead either to a first order transition or to an Ising-like critical behavior, the partition being formed by the tri-critical surface. Hence the theoretical wavering encountered in the literature concerning the nature of the Coulombic criticality may not appear senseless.

Congruent Spaces of Timed Complexity Classes
Creators: name: Syzdykov, Mirzakhmet
Publisher: name: Zenodo
Year: 2024

description: We discuss the meaning of the timed complexity classes within the bounded spaces along the “a priori '' of the past work. The discussed congruent spaces are reminiscent in the sense of the positive logic of the explained controversy which lies beyond the full length of the exposition of NP-hard problems in general due to Karp’s 21 problems. We can state that this dis-relation gives more comfortable addition to the changes in the co-worked companion problems that are to be solved within the times of complexity, as timed regular expressions can be evaluated in the positive logic giving the answer to the “P versus NP'' theoremwhich is omitted in the work due to the proposed conjecture before. Our main purpose is to introduce the timing-ness on the operators which are to be implemented within the linear time and memory space, as we go far beyond the term of determinism and nondeterminism for a property question arising in the variety of NPcomplete and congruent problems to be solved correctly using fuzzy logic of these spaces.

description: An effective action is obtained for the area and mass aspect of a thin shell of radiating self-gravitating matter. On following a mini-superspace approach, the geometry of the embedding space-time is not dynamical but fixed to be either Minkowski or Schwarzschild inside the shell and Vaidya in the external space filled with radiation. The Euler-Lagrange equations of motion are discussed and shown to entail the expected invariance of the effective Lagrangian under time-reparametrization. They are equivalent to the usual junction equations and suggest a macroscopic quasi-static thermodynamic description.

description: The proposed work was aimed to evaluate the hybridization of fuzzy C- means and competitive agglomeration for image segmentation. It is fuzzy clustering-based vector quantization algorithm. The method of segmenting a digital image into multiple segments is known as image segmentation. For segmentation, various methodologies based on standard techniques such as region rising, threshold technique, and watershed transform have been proposed. Because of the drawbacks of these approaches, segmentation based on clustering techniques has emerged. The central idea behind data clustering is that each cluster is represented by its centroid. In addition, the similarity of the input vectors to the centroid is used to represent each cluster. Clustering approaches are divided into two categories: parametric and nonparametric. Finding natural groupings in a dataset using a Euclidean distance between samples is a non-parametric technique. K-means, hierarchical, and spectral clustering are examples of non-parametric clustering. The lack of robustness to image noise is one of these methods' drawbacks. As a result, in image clustering and segmentation, a fuzzy segmentation technique has been commonly used. The most challenging aspect of fuzzy c-means is determining the number of clusters and choosing an objective function. As a result, we use a fuzzy clustering-based vector quantization algorithm. This algorithm makes use of a specialised objective function that combines fuzzy c-means and a competitive agglomeration term. This algorithm is fast, and the reconstructed images are of good quality.

description: A viable qubit must have a long coherence time $T_2$. In molecular nanomagnets $T_2$ is often limited at low temperatures by the presence of dipole and hyperfine interactions, which are often mitigated through sample dilution, chemical engineering and isotope substitution in synthesis. Atomic-clock transitions offer another route to reducing decoherence from environmental fields by reducing the effective susceptibility of the working transition to field fluctuations. The Cr$_7$Mn molecular nanomagnet, a heterometallic ring, features a clock transition at zero field. Both continuous-wave and spin-echo electron-spin resonance experiments on Cr$_7$Mn samples diluted via co-crystallization, show evidence of the effects of the clock transition with a maximum $T_2\sim350$ ns at 1.8 K. We discuss improvements to the experiment that may increase $T_2$ further.

Subjects: subject: Pattern Formation and Solitons (nlin.PS)

description: Excitable waves arise in many spatially-extended systems of either biological, chemical, or physical nature due to the interplay between local reaction and diffusion processes. Here we demonstrate that similar phenomena are encoded in the time-dynamics of an excitable system with two, hierarchically long delays. The transition from 1D localized structures to curved wave-segments is experimentally observed in an excitable semiconductor laser with two feedback loops and reproduced by numerical simulations of a prototypical model. While closely related to those found in 2D excitable media, wave patterns in delayed systems exhibit unobserved features originating from causality-related constraints. An appropriate dynamical representation of the data uncovers these phenomena and permits to interpret them as the result of an effective 2D advection-reaction-diffusion process.
Correlation Functions of Dense Polymers and c=-2 Conformal Field Theory

description: The model of dense lattice polymers is studied as an example of non-unitary Conformal Field Theory (CFT) with $c=-2$. ``Antisymmetric'' correlation functions of the model are proved to be given by the generalized Kirchhoff theorem. Continuous limit of the model is described by the free complex Grassmann field with null vacuum vector. The fundamental property of the Grassmann field and its twist field (both having non-positive conformal weights) is that they themselves suppress zero mode so that their correlation functions become non-trivial. The correlation functions of the fields with positive conformal weights are non-zero only in the presence of the Dirichlet operator that suppresses zero mode and imposes proper boundary conditions.

Second self
Creators: name: Kessel, Daniel
Publisher: name: No Publisher Supplied
Year: 2021

description: Second Self, a literary novel approximately 42,500 words long, is a modern retelling of the Victorian governess trope, remixing queer coming-of-age with elements of gothic storytelling. Set in the fall of 2010, Second Self centers on a semi-closeted NYU sophomore, Danny, who takes a job as a manny for Helen and Leonard Sand, a wealthy Upper West Side sexaganarian couple. Having a turbulent relationship to his own family—particularly his mother, an indigenous woman who left home when he was a child—and struggling to afford the cost of college, Danny welcomes his new role as caregiver for twins adopted out of foster care. He is also happy to distance himself from Nam, a sardonic film student and the object of his unrequited affection. But when Helen asks Danny to move into their luxurious Central Park co-op and take care of the children full time, he finds himself torn between the demands of his new surroundings and drawn back to his problematic past. Set in a world of claustrophobic wealth, yet told from an outsider’s perspective in a voice both earnest and knowingly camp, the book is about children and mothers, the hidden identities we carry and our imperfect attempts at love.
A STUDY ON THE CORRELATION BETWEEN SOCIO-DEMOGRAPHIC FACTORS AND HIGH BLOOD PRESSURE IN POLICE OFFICERS IN OBIO/AKPOR LOCAL GOVERNMENT AREA, RIVERS STATE
Creators: name: SAMUEL CHUKWUDI, OKORO

Subjects: socio-demographic factors, correlates, high blood pressure, police officers

description: The purpose of this study was to examine sociodemographic characteristics as a predictor of high blood pressure among police officers in Rivers State's Obio/Akpor Local Government Area. At a 0.05 alpha level, four objectives and three null hypotheses were established and tested. The study used a descriptive correlational strategy. The study enrolled one thousand, one hundred and forty-two (1,142) police officers. This study enrolled 300 police officers who used Taro Yamene. The sample for the study was selected using a two-stage selection technique. The data collection instrument was a self-administered structured questionnaire titled "Sociodemographic variables and Body Mass Index as Correlates of Hypertension." Cronbach's Alpha was used to determine the validated instrument's reliability coefficient (0.74). The acquired data were analyzed using statistical tools such as mean, standard deviation, ANOVA, and chi-square with the help of SPSS version 25.0. According to the study's findings in Table 1, there was around a 180 (60.6 percent) prevalence of hypertension among police officers in Rivers State's Obio/Akpor Local Government Area. The outcomes of this study established a strong association between body mass index (BMI) and hypertension among police officers in the Obio/Akpor Local Government Area of Rivers State (p.05). The outcomes of this study established a strong link between age and hypertension among police officers in the Obio/Akpor Local Government Area of Rivers State (p.05). The study's findings suggested that there was no significant link between gender and hypertension among police officers in Rivers State's Obio/Akpor Local Government Area (p >.05). It was discovered that police officers had a significant frequency of hypertension.

description: A lattice system of spinor atoms or molecules experiencing quadratic Zeeman effect is considered. This can be an optical lattice with sufficiently deep wells at lattice sites, so that the system is in an isolating state, where atoms are well localized. But their effective spins can move in the presence of external magnetic fields. The dynamics of spins, starting from an initial nonequilibrium state, is investigated. The system is immersed into a magnetic coil of an electric circuit, creating a magnetic feedback field. Two types of quadratic Zeeman effect are treated, a nonresonant, so-called static-current quadratic Zeeman effect and a quasi-resonant alternating-current quadratic Zeeman effect. Spin dynamics in these conditions is highly nonlinear. Different regimes of spin dynamics, starting from a strongly nonequilibrium state, are studied. Conditions for realizing fast spin reversal are found, which can be used in quantum information processing and spintronics.

description: Το πρόβλημα της κλιματικής αλλαγής αποτελεί πλέον πραγματικότητα και λαμβάνονται μέτρα για τον περιορισμό των επιπτώσεών του. Η σημαντικότερη διεθνής σύμβαση για την προστασία του περιβάλλοντος είναι το Πρωτόκολλο του Κιότο, στο πλαίσιο του υποίου δημιουργήθηκε ο Μηχανισμός Καθαρής Ανάπτυξης (ΜΚΑ). Ο ΜΚΑ παρέχει κίνητρα έτσι ώστε βιομηχανικά ανεπτυγμένες χώρες να χρηματοδοτήσουν προγράμματα για τη μείωση των εκπομπών αερίων του θερμοκηπίου στις αναπτυσσόμενες χώρες και ως αντιστάθμισμα να καρπωθούν μέρος των μειώσεων εκπομπών.
description: The problem of climate change constitutes henceforth reality and measures are being taken for the minimization of its impacts. The most important international convention on the protection of environment is the Protocol of Kyoto; in its frame the Clean Development Mechanism (CDM) was created. The CDM provides motivation so as the industrially developed countries finance programs for the reduction of greenhouse gases (GHGs) emissions in developing countries and thus indirectly decrease their own GHGs emissions.

description: The A+B --> C reaction-diffusion process is studied in a system where the reagents are separated by a semipermeable wall. We use reaction-diffusion equations to describe the process and to derive a scaling description for the long-time behavior of the reaction front. Furthermore, we show that a critical localization-delocalization transition takes place as a control parameter which depends on the initial densities and on the diffusion constants is varied. The transition is between a reaction front of finite width that is localized at the wall and a front which is detached and moves away from the wall. At the critical point, the reaction front remains at the wall but its width diverges with time [as t^(1/6) in mean-field approximation].

description: In presence of strong enough disorder one dimensional systems of interacting spinless fermions at non-zero filling factor are known to be in a many body localized phase. When represented in Fock space, the Hamiltonian of such a system looks like that of a single particle hopping on a Fock lattice in the presence of a random disordered potential. The coordination number of the Fock lattice increases linearly with the system size L in 1D. Thus in the thermodynamic limit, the disordered interacting problem in 1D maps on to an Anderson model with infinite coordination number. Despite this, this system displays localization which appears counterintuitive. A close observation of the on-site disorders on the Fock lattice reveals a large degree of correlation among them as they are derived from an exponentially smaller number of on-site disorders in real space. This indicates that the correlations between the on-site disorders on a Fock lattice has a strong effect on the localization properties of the corresponding many-body system. In this work we perform a systematic quantitative exploration of the nature of correlations of the Fock space potential required for localization. Without changing the typical strength of the on-site disorders in Fock lattice we show that changing the correlation strength can induce thermalization or localization in systems. From among the various functional forms of correlations we study through exact diagonalization, we find that only the linear variation of correlations with Hamming distance in Fock space is able to drive a thermal-MBL phase transition where the transition is driven by the correlation strength. Systems with the other forms of correlations we study are found to be ergodic.

description: We used Raman scattering to study the lattice and magnetic excitations in the hexagonal HoMnO3 single crystals. The E2 phonon mode at 237 cm-1 is affected by the magnetic order. This mode is related to the displacement of Mn and O ions in a-b plane and modulates the Mn-O-Mn bond angles in a-b plane and the in-plane Mn-Mn superexchange interaction. The mode at 269 cm-1 associated to the displacement of the apical Ho3+ ions along the c direction presents an abrupt change of slope at TN showing that the role of the rare earth ions can not be neglected in the magnetic transition. We have identified magnon and crystal field excitations. The temperature dependence of the magnetic excitations has been compared to the Mn and Ho moment and indicates that the exchange interaction pattern between Mn and Ho atoms drives the uniaxial anisotropy gap above the Mn-spin-rotation transition.
