description: We present a method where derivations of star-product algebras are used to build covariant derivatives for noncommutative gauge theory. We write down a noncommutative action by linking these derivations to a frame field induced by a nonconstant metric. An example is given where the action reduces in the classical limit to scalar electrodynamics on a curved background. We further use the Seiberg-Witten map to extend the formalism to arbitrary gauge groups. A proof of the existence of the Seiberg-Witten-map for an abelian gauge potential is given for the formality star-product. We also give explicit formulas for the Weyl ordered star-product and its Seiberg-Witten-maps up to second order.

On the transmission of crystallisation waves across the edge between the rough and faceted crystalline surfaces in superfluid 4He

description: The wavelike processes of crystallisation and melting or crystallisation waves are well-known to exist at the crystal 4He surface in its rough state. Below the roughening transition temperature the crystal surface experiences the transition to the smooth faceted state and the crystallisation waves represent the propagation of a train of crystalline steps at the velocity depending on the crystal step height. Here we analyse the transmission and reflection of crystallisation waves propagating across the crystal edge separating the crystal surface in the rough and faceted states.

description: Since the derivation of a well-defined $D\to4$ limit for 4D Einstein-Gauss-Bonnet (4DEGB) gravity coupled to a scalar field, there has been considerable interest in testing it as an alternative to Einstein's general theory of relativity. Past work has shown that this theory hosts interesting compact star solutions which are smaller in radius than a Schwarzschild black hole of the same mass in general relativity (GR), though the stability of such objects has been subject to question. In this paper we solve the equations for radial perturbations of neutron stars in the 4DEGB theory with Skyrme Lyon (SLy)/Brussels-Montreal Skyrme functionals (BSk) class equations of state (EOSs), along with the Müller-Serot (MS2) EOS, and show that the coincidence of stability and maximum mass points in GR is still present in this modified theory, with the interesting additional feature of solutions re-approaching stability near the black hole solution on the mass-radius diagram. Besides this, as expected from past work, we find that larger values of the 4DEGB coupling $α$ tend to increase the mass of neutron stars of the same radius (due to a larger $α$ weakening gravity) and move the maximum mass points of the solution branches closer to the black hole horizon.

description: A sequential effect algebra (SEA) is an effect algebra equipped with a sequential product operation modeled after the Lüders product $(a,b)\mapsto \sqrt{a}b\sqrt{a}$ on C*-algebras. A SEA is called normal when it has all suprema of directed sets, and the sequential product interacts suitably with these suprema. The effects on a Hilbert space and the unit interval of a von Neumann or JBW algebra are examples of normal SEAs that are in addition convex, i.e. possess a suitable action of the real unit interval on the algebra. Complete Boolean algebras form normal SEAs too, which are convex only when $0=1$. We show that any normal SEA $E$ splits as a direct sum $E\equiv E_b\oplus E_c \oplus E_{ac}$ of a complete Boolean algebra $E_b$, a convex normal SEA $E_c$, and a newly identified type of normal SEA $E_{ac}$ we dub purely almost-convex. Along the way we show, among other things, that a SEA which contains only idempotents must be a Boolean algebra; and we establish a spectral theorem using which we settle for the class of normal SEAs a problem of Gudder regarding the uniqueness of square roots. After establishing our main result, we propose a simple extra axiom for normal SEAs that excludes the seemingly pathological a-convex SEAs. We conclude the paper by a study of SEAs with an associative sequential product. We find that associativity forces normal SEAs satisfying our new axiom to be commutative, shedding light on the question of why the sequential product in quantum theory should be non-associative.

description: Effective leadership serves as the cornerstone for the success of businesses, with organizational decisions shaping the collective future. However, the implementation of these decisions and the timely execution of actions depend heavily on the individual's adeptness in time management. While organizational management endeavors to optimize resources and maximize returns, the efficiency of these efforts hinges on the intricate aspect of time allocation by individuals (Mitch, 2017). Philpot (2019) underscores the significance of time management, emphasizing the pivotal role of planning in extracting optimal value from the day.

This study delves into the critical interplay between leadership, organizational goals, and individual time management. Time, being an invaluable resource, stands at the nexus of managerial endeavors, determining the realization of organizational objectives. The temporal nature of time adds an element of urgency, as once spent, it cannot be retrieved. Every manager, whether at the organizational or individual level, grapples with the challenge of enhancing time management to propel productivity and achieve overarching goals.

Drawing on the insights of Mitch (2017) and Philpot (2019), this research aims to unravel the intricacies of effective time management in the context of leadership and organizational success. It recognizes time as a finite and irreplaceable asset, advocating for strategies that not only optimize its utilization but also contribute to the attainment of broader business objectives. The study caters to the needs of both organizational leaders seeking business development and individuals striving to enhance their personal time management skills.

In conclusion, the study posits time management as a linchpin in the realm of effective leadership and organizational efficiency. It advocates for a comprehensive understanding of the temporal constraints faced by managers and individuals alike, offering insights that can inform strategic approaches to maximize productivity and achieve enduring success.

description: We have measured the radial velocities of five 51 Peg-type stars and one star with constant velocity. Our measurements, on 20 Åcentered at 3947 Å, were conventional using Th/Ar comparison spectra taken every 20 or 40 minutes between the stellar exposures. Existing IRAF routines were used for the reduction. We find $σ_{RV}$ $\leq$ 20 m s$^{-1}$, provided 4 measurements (out of 72) with residuals $>5σ_{RV}$ are neglected. The observations were made with the CFHT Gecko spectrograph, fiber-fed with the CAFE system (R$\sim$110,000). $σ_{RV}$ $\leq$10 m s$^{-1}$ seems possible with additional care. This study was incidental to the main program and so not exhaustive but the small value of $σ_{RV}$ implies that the fiber feed/image slicer system on Gecko + CAFE, essentially eliminates the long standing problem of guiding errors in radial velocity measurements. We are not suggesting this conventional approach for serious Doppler planet searches (especially with Gecko which has such a small multiplex gain), but the precision is valuable for observations made in spectral regions remote from telluric lines or captive-gas fiducials. Instrument builders might consider the advantages of the CAFE optics which incorporate agitation and invert the object and pupil for slit and grating illumination in future spectrograph designs.

description: We study the collective behaviour of a close packed monolayer of non-Brownian particles at a fluid-liquid interface. Such a particle raft forms a two-dimensional elastic solid and can support anisotropic stresses and strains, e.g. it buckles in uniaxial compression and cracks in tension. We characterise this solid in terms of a Young's modulus and Poisson ratio derived from simple theoretical considerations and show the validity of these estimates by using an experimental buckling assay to deduce the Young's modulus.

Galaxy mass profiles from strong gravitational lensing
Creators: name: O'Riordan, Conor
Publisher: name: Imperial College London
Year: 2020

description: In this thesis we develop a theory for constraining power-law mass profiles with strong lensing observations. We account for both positional and flux information and show that strong lensing can provide precise constraints on the mass profiles of galaxies, and, that these constraints apply over more than just the radial range of the images. Beginning with the circular power-law model, we find an analytic expression which relates the image position ratio and the flux ratio to the slope. We then derive an expression for the uncertainty on the slope. This result is verified by finding the slope uncertainty in a series of mock observations where a circular lens is fit with a power-law ellipsoid. We then extend this analysis to elliptical systems. Here we show that for any two-image system the slope uncertainty is determined by the expression for the circular case. The constraint therefore also relies on a combination of positional and flux information. In the four-image systems we identify two separate cases. First, when the source is aligned with the axis we again find an analytic expression for the slope uncertainty. Second, in the general four-image systems we show that the slope is strongly constrained by the positional information alone. Finally we formulate a truncated power-law model which we use with mock observations to show that the slope interior to the lensed images is constrained, contrary to the standard view expressed in the literature. The truncated power-law results are then used to formulate a broken power-law, a more flexible lens model with an inner and outer slope, continuous across a break radius. Fitting to mock observations with the broken power-law shows that the inner and outer slopes are well constrained. This shows for the first time that lensing observations alone can constrain power-law mass profiles of lens galaxies in significant detail.

description: When computed to next-to-leading order in perturbative QCD, the non-linear Balitsky-Kovchegov (BK) equation for the high-energy evolution of the dipole-hadron scattering appears to be unstable. We show that this instability can be avoided by using the rapidity of the dense hadronic target (instead of that of the dilute dipole projectile) as the evolution time. Using this variable, we construct a collinearly-improved version of the BK equation, where the dominant radiative corrections to the kernel -- those enhanced by double collinear logarithms -- are resummed to all orders.

description: ABSTRACT

Artificial Intelligence (AI) has emerged as a transformative tool in the field of education, offering enhanced efficiency, personalized learning, and the potential to revolutionize academic practices. However, while AI has proven its utility in various educational contexts, there is growing concern that it may be perceived as a substitute for human intellect and educators, rather than as a tool to complement their work. This paper aims to explore the role of AI in education, emphasizing the need for it to be seen as a tool rather than a god. Through a systematic literature review of six recent papers published in 2025, this study examines the benefits and limitations of AI in academia, exploring how AI can enhance student engagement, improve academic outcomes, and streamline educational processes. It also discusses the dangers of over-reliance on AI, highlighting the importance of maintaining human oversight and engagement to preserve the integrity of academic work. The findings suggest that AI can be a powerful academic partner, but its role should be carefully managed to prevent diminishing critical thinking, emotional intelligence, and human interaction in the learning process. The paper concludes with a call for a balanced approach to AI integration in education, where AI is leveraged as a tool to support, not replace, human-driven educational practices. Furthermore, it proposes directions for future research to ensure that AI is used ethically and effectively in academic settings.

description: Since 2011, the war in Syria has resulted in the displacement of 12.2 million people. Over 5.6 million have fled Syria to seek asylum in neighbouring countries, while 6.6 million have been internally displaced. Family separation, with significant psychological, social and economic implications, is a key concern for those who flee violence and cross international borders. This qualitative study sought to understand the causes of separation among Syrian families in Jordan and the obstacles to family reunification. Semi-structured, in-depth interviews were conducted with 85 Syrian refugee families identified as having separated family members. We present critical moments during migration when family separation occurs: (1) while fleeing Syria, (2) while residing in Jordan and (3) pre-existing separation due to work or travel that was exacerbated by the conflict. We also highlight the factors that perpetuate separation among families, preventing or delaying them from reuniting. These findings may help to inform more humane family reunification practices as well as identify future research and learning needs.
Quantum correlations: foundational and practical aspects

Publisher: name: Imperial College London
Year: 2021

description: Quantum correlations have been an integral if sometimes discomforting aspect of quantum theory for over 85 years. From the early thought-experiments where they were used to argue that quantum mechanics was incomplete, through to their central position as resources in the modern theory of quantum information theory, quantum correlations have proved a hugely rich topic of study. This thesis explores a range of practical and foundational aspects within this ever developing field. Having reviewed fundamental material, we turn to consider the quantum correlations for a task termed anonymous metrology. This is used to demonstrate an operational distinction within the hierarchy of quantum correlations. Building from this we formulate the concept of quantum delocalised interactions, making use of quantum games to study the necessary correlations. With these we establish strong connections to the concurrence monotone and additionally a link with quantum teleportation. We then move to considering entanglement under motion when relativity is accounted for. We demonstrate how the entanglement between internal energy and motional states can be affected by boosts in an analogous way to the known behaviour for spins, and in a more straightforward manner. We then show how this understanding sheds light on the topic of proper time for quantum clocks. Finally we consider a protocol where entanglement can be used to witness non-classicality of gravity. We present improvements which help to bring the scheme closer to experimental feasibility, together with pointing out a potential loophole and how to close it.

On the relation between quantum mechanical probabilities and event frequencies

Publisher: name: arXiv
Year: 2004
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: The probability `measure' for measurements at two consecutive moments of time is non-additive. These probabilities, on the other hand, may be determined by the limit of relative frequency of measured events, which are by nature additive. We demonstrate that there are only two ways to resolve this problem. The first solution places emphasis on the precise use of the concept of conditional probability for successive measurements. The physically correct conditional probabilities define additive probabilities for two-time measurements. These probabilities depend explicitly on the resolution of the physical device and do not, therefore, correspond to a function of the associated projection operators. It follows that quantum theory distinguishes between physical events and propositions about events, the latter are not represented by projection operators and that the outcomes of two-time experiments cannot be described by quantum logic. The alternative explanation is rather radical: it is conceivable that the relative frequencies for two-time measurements do not converge, unless a particular consistency condition is satisfied. If this is true, a strong revision of the quantum mechanical formalism may prove necessary. We stress that it is possible to perform experiments that will distinguish the two alternatives.

description: Domestic chickens (Gallus gallus domesticus) were exposed to imidacloprid by gavage once daily for 7 consecutive days at 0, 0.03, 0.34, 3.42, 10.25, and 15.5 mg/kg/day (n = 20 per group; 5 6-week-old males, 5 6-week-old females, 5 9-week-old males, and 5 9-week-old females). The severity and duration of neurobehavioral abnormalities were recorded. Components of the innate and adaptive immune system were assessed with 7 standard functional assays. Temporary neurobehavioral abnormalities were observed in a dose-dependent manner, including muscle tremors, ataxia, and depressed mentation. Based upon mean clinical severity scores, the no observed adverse effect level (NOAEL) was 3.42 mg/kg/day, and the lowest observed adverse effect level (LOAEL) was 10.25 mg/kg/day. The effective dose value for the presence of any neurobehavioral abnormalities in 50% of the test group (ED50) was 4.62 ± 0.98 mg/kg/day. The ED50 for an adjusted score that included both severity and duration of neurobehavioral abnormalities was 11.24 ± 9.33 mg/kg/day. These ED50 values are equivalent to a 1 kg bird ingesting 29 or 70 imidacloprid treated soybean seeds respectively. Immunotoxicity was not documented, possible causes include the assays were insensitive, relevant immune functions were not examined, or imidacloprid is not immunotoxic at this dosing schedule in this species. Neurobehavioral abnormalities were a more sensitive indicator of the sublethal effects of imidacloprid than immunotoxicity.

description: In a scoping study on the role of local faith communities in relation to child development and learning in low- and middle-income countries, we note the need for more scholarly attention on this topic, especially in the areas of ECD and primary and secondary education. We find very little literature that explores the current contributions of these faith communities or the impact of interventions. Most literature focuses on interventions driven by international actors that engage faith-actors in instrumentalist ways. We argue for an approach that seeks to recognize and support faith-communities as existing systems that support child development and learning, and believe such an approach will be more sustainable, respectful, and effective.

description: There is a one-to-one correspondence between involutory latin quandles and uniquely $2$-divisible Bruck loops. Bruck loops of odd prime power order are centrally nilpotent. Using linear-algebraic approach to central extensions, we enumerate Bruck loops (and hence involutory latin quandles) of order $3^k$ for $k\le 5$, except for those loops that are central extensions of the cyclic group of order $3$ by the elementary abelian group of order $3^4$. Among the constructed loops there is a Bruck loop of order $3^5$ whose associated $Γ$-loop is not a commutative automorphic loop. We independently enumerate commutative automorphic loops of order $3^k$ for $k\le 5$, with the same omission as in the case of Bruck loops.

In the limit of zero angular momentum, both types of solutions collapse to zero radius, giving rise respectively to a degenerate string configuration corresponding to a particle travelling with the speed of light and to a static straight string configuration. These solutions share all the properties of fundamental strings and do not have the pathological behavior of other solutions previously found in this context. A short discussion on the ``generalized gauge transformations'' suggested by Sen is used to justify the validity of our approach.

description: The spatial distribution of the background events may affect the source detection capability of IBIS at high energies (> 200 keV) for both ISGRI and PICsIT layers. The observed background is found to be variable and spatially structured, and in some cases its properties strongly deviate from the expected statistical behaviour. Background correction methods are then necessary to improve the quality of the shadowgrams obtained from sources. In order to perform an efficient flat-fielding the response of the detector to both source gamma-rays and background events is investigated using data from Monte Carlo simulations and in-flight calibration observations.

Pulsed hot filament methods have long been known and well studied. This is due to the fact that these methods have advantages over stationary methods: short preparation time for the experiment, short time for the experiment, small volume of the measuring cell, and others. Standards for this method were published in the USA (ASTM C1113 / C1113M - 09), England (BS EN 993-15: 2005, BS EN 993-14: 2008). In all these methods and works in which the "hot wire" method was applied, the properties of substances and materials from room to high temperatures are often studied. In works that study the critical parameters of liquids / gases (mixtures), no attention is paid to the dependence of the resistance of the used sensor (thermistor, usually made of platinum). However, with the exploration of outer space, where the cold reigns about 4 ° K, and industrial installations operating at low temperatures, there is a need to study the thermophysical properties (TPP) of substances and materials at low temperatures. One of the methods suitable for studying TPS at low temperatures is the "hot filament" method in its various versions. Accounting for the nonlinear change in resistance of a thermoresistive measuring sensor at cryogenic temperatures is shown in this work. Prior to this, the literature did not describe the application of these dependencies in relation to the "hot thread" method.

description: To decrease patient waiting time for diagnosis of the Coronary Artery Disease, automatic methods are applied to identify its severity using Coronary Computed Tomography Angiography scans or extracted Multiplanar Reconstruction (MPR) images, giving doctors a second-opinion on the priority of each case. The main disadvantage of previous studies is the lack of large set of data that could guarantee their reliability. Another limitation is the usage of handcrafted features requiring manual preprocessing, such as centerline extraction. We overcome both limitations by applying a different automated approach based on ShuffleNet V2 network architecture and testing it on the proposed collected dataset of MPR images, which is bigger than any other used in this field before. We also omit centerline extraction step and train and test our model using whole curved MPR images of 708 and 105 patients, respectively. The model predicts one of three classes: 'no stenosis' for normal, 'non-significant' - 1-50% of stenosis detected, 'significant' - more than 50% of stenosis. We demonstrate model's interpretability through visualization of the most important features selected by the network. For stenosis score classification, the method shows improved performance comparing to previous works, achieving 80% accuracy on the patient level. Our code is publicly available.

description: We study the clustering properties of advected, non-interacting,passive scalar particles in a Burgers fluid with noise, a problem which maps to that of passive sliding particles moving under gravity on a surface evolving through the Kardar-Parisi-Zhang equation. Numerical simulations show that both the density-density correlation function and the single-site mass distribution scale with system size. The scaling functions diverge at small argument, indicating strong clustering of particles. We analytically evaluate the scaling functions for the two-point correlation and mass distribution of noninteracting particles in thermal equilibrium in a random landscape, and find that the results are remarkably similar to those for nonequilibrium advection.

Secondo alcuni modelli di formazione stellare, i getti bipolari prodotti dalle protostelle spazzano via il gas circostante necessario per l’accrescimento, creando cavità sempre più grandi man mano che la stella evolve. I risultati di un nuovo studio, in uscita su The Astrophysical Journal, sono in disaccordo con questa teoria
Periodic Flux Variability of Stars due to the Reflex Doppler Effect Induced by Planetary Companions

Publisher: name: arXiv
Year: 2003

description: Upcoming space-based photometric satellites offer the possibility of detecting continuum flux variability at the micro-magnitude level. We show that the Doppler flux variability induced by the reflex motion of stars due to planetary companions has an amplitude of (3-alpha)K/c, where K is the reflex radial velocity amplitude and alpha is the logarithmic slope of source spectral flux in the observed frequency band. For many of the known close-in planetary systems with periods less than ~0.2 years, the periodic Doppler variability is of order a micromagnitude, and is significant relative to the variability caused by reflected light from the planetary companion. For companions with periods greater than ~0.2 years, the Doppler signal is larger than the reflected light signal. We show that the future photometric satellites should reach the sensitivity to detect this Doppler variability. In particular, the Kepler satellite should have the photon-noise sensitivity to detect at a signal-to-noise ratio > 5, all planets with minimum mass greater than 5 Jupiter masses, and periods less than 0.1 years around the 10,000 main-sequence stars with spectral types A through K and apparent magnitude V<12 in its field-of-view.

description: In principle, the complete spectrum and bound-state wave functions of a quantum field theory can be determined by finding the eigenvalues and eigensolutions of its light-cone Hamiltonian. One of the challenges in obtaining nonperturbative solutions for gauge theories such as QCD using light-cone Hamiltonian methods is to renormalize the theory while preserving Lorentz symmetries and gauge invariance. For example, the truncation of the light-cone Fock space leads to uncompensated ultraviolet divergences. We present two methods for consistently regularizing light-cone-quantized gauge theories in Feynman and light-cone gauges: (1) the introduction of a spectrum of Pauli-Villars fields which produces a finite theory while preserving Lorentz invariance; (2) the augmentation of the gauge-theory Lagrangian with higher derivatives. In the latter case, which is applicable to light-cone gauge (A^+ = 0), the A^- component of the gauge field is maintained as an independent degree of freedom rather than a constraint. Finite-mass Pauli-Villars regulators can also be used to compensate for neglected higher Fock states. As a test case, we apply these regularization procedures to an approximate nonperturbative computation of the anomalous magnetic moment of the electron in QED as a first attempt to meet Feynman's famous challenge.

description: We study the lowest-order modifications of the static potential for Born-Infeld electrodynamics and for the $θ$-expanded version of the noncommutative U(1) gauge theory, within the framework of the gauge-invariant but path-dependent variables formalism. The calculation shows a long-range correction ($1/r^5$-type) to the Coulomb potential in Born-Infeld electrodynamics. However, the Coulomb nature of the potential (to order $e^2$) is preserved in noncommutative electrodynamics.

description: We investigate field-line separation in strong MHD turbulence analytically and with direct numerical simulations. We find that in the static-magnetic-field approximation the thermal conductivity in galaxy clusters is reduced by a factor of about 5-10 relative to the Spitzer thermal conductivity of a non-magnetized plasma. We also estimate how the thermal conductivity would be affected by efficient turbulent resistivity.
