description: We describe a new algorithm for computing Whitney stratifications of complex projective varieties. The main ingredients are (a) an algebraic criterion, due to Lê and Teissier, which reformulates Whitney regularity in terms of conormal spaces and maps, and (b) a new interpretation of this conormal criterion via primary decomposition, which can be practically implemented on a computer. We show that this algorithm improves upon the existing state of the art by several orders of magnitude, even for relatively small input varieties. En route, we introduce related algorithms for efficiently stratifying affine varieties, flags on a given variety, and algebraic maps.

title: An examination of the impact of colour response cards on teacher-pupil classroom interaction in girls’ primary schools in Saudi Arabia
Creators: name: Alghamdi, Sharifah
Publisher: name: University of Reading
Year: 2025

description: Pupils’ disruptive behaviour and a lack of academic engagement are two important challenges of classroom management. They affect the teacher’s ability to deliver instruction and engage pupils in learning. In this study, an intervention was designed to address these issues, using colour response cards, these being reusable signs or cards, used by pupils to indicate their responses to the teacher’s questions. Colour response cards are cost-effective, simple to use, and effective for managing pupils. Pupils’ perceptions of using them and the impact of these cards on teachers’ decisionmaking were therefore investigated in this study, specifically in two girls’ primary schools in Saudi Arabia. A quasi-experimental, sequential explanatory mixed methods design was adopted with a sample of 169 pupils aged 6-7 years (School A: n=99; School B: n=70), as the research focus was on Year One primary school pupils. The disruptive behaviour and academic engagement of nine randomly selected pupils from School A and School B were recorded during mathematics lessons, using an observation checklist at three stages: pre-intervention (before using the colour response cards), introduction (while using the colour response cards), and established (after using the colour response cards). Following the intervention, a quantitative questionnaire survey was conducted to collect pupils’ perceptions of using the colour response cards, while qualitative semi-structured interviews and a journal record were implemented with the participating teachers to examine their perceptions of using the cards, and gauge the impact of this approach on their decision-making. The quantitative analysis of pupils’ behavioural data, using ANOVA, revealed a substantial decrease in pupils’ disruptive behaviour and an increase in their academic engagement in the intervention group, gradually becoming major by the end of the intervention. The pupils’ survey results indicated that they enjoyed the colour response card approach, recognised that it helped them to actively engage in learning, and to improve their interaction with teachers. Meanwhile, the findings from the qualitative analysis of the teachers’ interviews revealed that most of the teachers identified the intervention as very useful and that it helped them manage the classroom more effectively. Overall, the results demonstrated that colour response cards are effective in reducing disruptive behaviour and increasing academic engagement among primary school pupils.
On the Shroer-Sauer-Ott-Yorke predictability conjecture for time-delay embeddings

description: Shroer, Sauer, Ott and Yorke conjectured in 1998 that the Takens delay embedding theorem can be improved in a probabilistic context. More precisely, their conjecture states that if $μ$ is a natural measure for a smooth diffeomorphism of a Riemannian manifold and $k$ is greater than the information dimension of $μ$, then $k$ time-delayed measurements of a one-dimensional observable $h$ are generically sufficient for a predictable reconstruction of $μ$-almost every initial point of the original system. This reduces by half the number of required measurements, compared to the standard (deterministic) setup. We prove the conjecture for ergodic measures and show that it holds for a generic smooth diffeomorphism, if the information dimension is replaced by the Hausdorff one. To this aim, we prove a general version of predictable embedding theorem for injective Lipschitz maps on compact sets and arbitrary Borel probability measures. We also construct an example of a $C^\infty$-smooth diffeomorphism with a natural measure, for which the conjecture does not hold in its original formulation.

description: We present the Waves in Nearby Disk galaxies Survey (WiNDS) consisting of 40 nearby low inclination disk galaxies observed through H$α$ high-resolution Fabry Perot interferometry. WiNDS consists of 12 new galaxy observations and 28 data archived observations obtained from different galaxy surveys. We derive two-dimensional line-of-sight velocity fields that are analyzed to identify the possible presence of vertical velocity flows in the galactic disks of these low-inclination late-type galaxies using velocity residual maps, derived from the subtraction of an axisymmetric rotation model to rotational velocity map. Large and globally coherent flows in the line-of-sight velocity of nearly face-on galaxies can be associated with large vertical displacement of the disk with respect to its mid-plane. Our goal is to characterize how frequent vertical perturbations, such as those observed in the Milky Way, arise in the Local Universe. Our currently available data have allowed us to identify 20$\%$ of WiNDS galaxies with strong velocity perturbations that are consistent with vertically perturbed galactic disks.

description: This paper constructs an analytic description for the late stages of giant planet formation. During this phase of evolution, the planet gains the majority of its final mass through gas accretion at a rapid rate. This work determines the density and velocity fields for material falling onto the central planet and its circumplanetary disk, and finds the corresponding column density of this infalling envelope. We derive a steady-state solution for the surface density of the disk as a function of its viscosity (including the limiting case where no disk accretion occurs). Planetary magnetic fields truncate the inner edge of the disk and determine the boundary conditions for mass accretion onto the planet from both direct infall and from the disk. The properties of the forming planet and its circumplanetary disk are determined, including the luminosity contributions from infall onto the planet and disk surfaces, and from disk viscosity. The radiative signature of the planet formation process is explored using a quasi-spherical treatment of the emergent spectral energy distributions. The analytic solutions developed herein show how the protoplanet properties (envelope density distribution, velocity field, column density, disk surface density, luminosity, and radiative signatures) vary with input parameters (instantaneous mass, orbital location, accretion rate, and planetary magnetic field strength).

The Challenges of Global Sourcing Practices in Relation to Procurement Performance: The Case of Ethio telecom
Creators: name: Mesay, Girum
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2019

description: The main purpose of this study was to assess the challenges of global sourcing practices and to evaluate their impact on procurement performance of ethio telecom. The study used both primary and secondary data sources. Primary data was collected through close and open ended questionnaires and semi-structured interviews. Questionnaires were distributed for purposefully selected 50 respondents from ethio telecom's supply chain division. Interviews were conducted with 5 middle level managers and supervisors who participated directly or indirectly in the global sourcing practices of the company. Data was analyzed through descriptive statistical methods such as percentages, frequencies, mean and standard deviation. Inferential analyses were also used in relation to bivariate correlation and linear regression to show the relationships of variables. Major findings of the study indicated that foreign currency shortage and fluctuation, incomplete and unplanned purchase requests, delay of letter of credit at bank, delay in delivery from supplier, limited logistical facilities, and high customs tariff were the main challenges that seriously impacted the global sourcing practices and procurement performance of the company. Study findings also showed that challenges of global sourcing had negative and significant effect on procurement performance. Finally, from the above findings the study concluded that the global sourcing practices and procurement performance of ethio telecom have been impacted by several challenges of global sourcing practices with predictive ability of 18.2 percent variation on procurement performance (R squared =0.182). Thus, to solve these challenges, the study recommended the company to find immediate solutions for the above mentioned challenges in cooperation with concerned stakeholders through creating awareness and also through engaging in SLA & OLA with end users, suppliers and all other stakeholders.

description: Measuring the time it takes to remove an electron from an atom or molecule during photoionization using newly developed attosecond spectroscopies has been a focus of many recent experiments. However, the outcome of such measurement depends on measurement protocols and specific observables available in each particular experiment. One of such protocols relies on high harmonic generation. First, we derive rigorous and general expressions for ionization and recombination times in high harmonic generation experiments. We show that these times are different from, but related to ionization times measured in photo-electron spectroscopy, i.e. using attosecond streak camera, RABBITT and atto-clock methods. Second, we use the Analytical R-Matrix theory (ARM) to calculate these times and compare them with experimental values.

description: We present here the model dependent and independent sensitivity studies for NaI detectors designed to test the DAMA result, and compare the predicted limits from SABRE with the present performance of both ANAIS and COSINE. We find that the strongest discovery and exclusion limits are set by a detector with the lowest background (assuming equal run times), and also note that our method correctly computes the present exclusion limits previously published by ANAIS and COSINE. In particular, with a target mass of 50 kg and background rate of 0.36 cpd/kg/keV (after veto), SABRE will be able to exclude the DAMA signal with 3$σ$ confidence or `discover' it with 5$σ$ confidence within 2 years. This strongly motivates the quest for ever lower backgrounds in NaI detectors.

description: The binary bracket of a Courant algebroid structure on $(E,\langle \cdot,\cdot \rangle)$ can be extended to a $n$-ary bracket on $Γ(E)$, yielding a multi-Courant algebroid. These $n$-ary brackets form a Poisson algebra and were defined, in an algebraic setting, by Keller and Waldmann. We construct a higher geometric version of Keller-Waldmann Poisson algebra and define higher multi-Courant algebroids. As Courant algebroid structures can be seen as degree $3$ functions on a graded symplectic manifold of degree $2$, higher multi-Courant structures can be seen as functions of degree $n\geq 3$ on that graded symplectic manifold.

description: We study the change of the Laughlin states under large deformations of the geometry of the sphere and the plane, associated with Mabuchi geodesics on the space of metrics with Hamiltonian $S^1$-symmetry. For geodesics associated with the square of the symmetry generator, as the geodesic time goes to infinity, the geometry of the sphere becomes that of a thin cigar collapsing to a line and the Laughlin states become concentrated on a discrete set of $S^1$--orbits, corresponding to Bohr-Sommerfeld orbits of geometric quantization. The lifting of the Mabuchi geodesics to the bundle of quantum states, to which the Laughlin states belong, is achieved via generalized coherent state transforms, which correspond to the KZ parallel transport of Chern-Simons theory.

In addition we also consider this paper as scientific divulgation of the IMB advertisement. In this paper we show the main tool (quantum gates) present in the IBM-QE and, through a simple strategy, we discuss about a possible decoherence source in the IBM 5 q-bit chips. As an example of application of our study, we show how to implement the quantum teleportation using the IBM-QE.

description: Based on the long-term light curves collected from the Catalina Sky Survey (CSS) (from 2005 to 2013) and the All-Sky Automated Survey for Supernovae (ASAS-SN) (from 2014 to 2018), optical quasi-periodic oscillations (QPOs) about 300 days can be well determined in the well-known blazar PKS~2155-304 through four different methods: the generalized Lomb-Scargle periodogram (GLSP) method, the weighted wavelet Z-transform (WWZ) technique, the epoch-folded method and redfit method. The GLSP determined significance level for the periodicity is higher than 99.9999\% based on a false alarm probability. The redfit provided confidence level for the periodicity is higher than 99\% in ASAS-SN light curve, after considering the effects of red noise. Based on continuous autoregressive (CAR) process created artificial light curves, the probability of detecting fake QPOs is lower than 0.8\%. The determined optical periodicity of 300 days from CSS and ASAS-SN light curves is well consistent with the reported optical periodicity in the literature. Moreover, three possible models are discussed to explain the optical QPOs in PKS 2155-304: the relativistic Frame-dragging effect, the binary black hole (BBH) model and the jet precession model.

description: We report the discovery of 1RXH J082623.6-505741, a 10.4 hr orbital period compact binary. Modeling extensive optical photometry and spectroscopy reveals a $\sim 0.4 M_{\odot}$ K-type secondary transferring mass through a low-state accretion disk to a non-magnetic $\sim 0.8 M_{\odot}$ white dwarf. The secondary is overluminous for its mass and dominates the optical spectra at all epochs, and must be evolved to fill its Roche Lobe at this orbital period. The X-ray luminosity $L_X \sim 1$-$2 \times 10^{32}$ erg s$^{-1}$ derived from both new XMM-Newton and archival observations, although high compared to most CVs, still only requires a modest accretion rate onto the white dwarf of $\dot{M} \sim 3 \times 10^{-11}$ to $3 \times 10^{-10} M_{\odot}$ yr$^{-1}$, lower than expected for a cataclysmic variable with an evolved secondary. No dwarf nova outbursts have yet been observed from the system, consistent with the low derived mass transfer rate. Several other cataclysmic variables with similar orbital periods also show unexpectedly low mass transfer rates, even though selection effects disfavor the discovery of binaries with these properties. This suggests the abundance and evolutionary state of long-period, low mass transfer rate cataclysmic variables is worthy of additional attention.

description: Poor air quality is linked to numerous adverse health effects including strokes, heart attacks, and premature death. Improving energy efficiency in the industrial sector reduces air emissions and yields health benefits. One of these strategies, replacing an existing grid boiler (GB) with a combined heat and power (CHP) system, can improve a facility’s energy efficiency but can also increase local air emissions, which in turn can affect health outcomes. Previous studies have considered air-emissions and health outcomes of CHP system installation at a single location, but few studies have investigated the regional air quality and health impacts of replacing an existing GB with new CHP system. This study estimates the emission changes and associated health impacts of this shift in 14 regions in the US, representing different electricity generation profiles. It assumes that one manufacturing facility in each region switches from an existing GB to a CHP system. The monetized annual US health benefits of shifting a single GB to a CHP in each of the 14 regions range from $-5.3 to 0.55 million (2022 USD), while including CHP emission control increases the benefits by 100–170% ($9,000 to 1.15 million (2022 USD)). This study also includes a sensitivity analysis, which suggests that the facility location (region, state, and county), boiler efficiency, and emission control of the CHP are key factors that would determine whether shifting from a GB to CHP system would result in health benefits or burdens. Implications: Combined heat and power (CHP) systems offer industrial facilities the opportunity to improve their energy efficiency and reduce greenhouse gas emissions. However, CHP systems also combust more fuel on site and can also increase local air emissions. This study evaluates how converting an existing grid boiler (GB) system to a CHP system (with or without emission control) affects local (from combustion) and regional emissions (from electricity consumption) and the associated health burdens in different US regions. A facility can use this study’s analysis as an example for estimating the tradeoffs between local emission changes, regional emission changes, and health effects. It also provides a comparison between the incremental cost of adding SCR (compared to uncontrolled CHPs) and the NPV of the monetized health benefits associated with adding the SCR.

description: The photon-photon interaction in ultra-relativistic heavy-ion collision is a source of the $(e^+,e^-)$ pairs. The photon-photon fusion leads the lepton creation in the broad configuration space around "collision" point. Those created close to heavy nuclei may undergo strong interaction with them. The impact parameter space distribution of electrons and positrons are calculated within the b-space EPA model of such collisions. The evolution due to the electromagnetic interaction of $(e^+,e^-)$ with nuclei is studied, and the distortion of rapidity and transverse momentum distributions are shown. We show first exploratory results for the reaction Pb+Pb at $\sqrt{s_{NN}}=$ 17.3 GeV (SPS) and 200 GeV (RHIC) energies. We provide results for selected creation points and when integrating over their position as dictated by the $b$-space EPA model. We observe strong effects at low transverse momenta, so far not measured regions of the phase space. In particular, we predict a possible sizeable accumulation of electrons with rapidities close to the beam rapidity. The EM effects lead to asymmetry in the production of electrons and positrons.

description: We review various methods used to estimate uncertainties in quantum correlation functions, such as parton distribution functions (PDFs). Using a toy model of a PDF, we compare the uncertainty estimates yielded by the traditional Hessian and data resampling methods, as well as from explicitly Bayesian analyses using nested sampling or hybrid Markov chain Monte Carlo techniques. We investigate how uncertainty bands derived from neural network approaches depend on details of the network training, and how they compare to the uncertainties obtained from more traditional methods with a specific underlying parametrization. Our results show that utilizing a neural network on a simplified example of PDF data has the potential to inflate uncertainties, in part due to the cross validation procedure that is generally used to avoid overfitting data.

Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2017

description: The main purpose of conducting this study was to investigate the understanding, practical implementation of Supply chain management practices towards organizational performance in Modern Building Industries PLC, a member of MIDROC Technology Group. Five key dimensions of Supply chain management practices (strategic supplier partnership, customer relationship, quality and level of information sharing and lean practices) were used as independent variables accompanied by different measurement instruments under each variable, while market and operational/financial performance variables were used to measure the organizational performance. Data were obtained via questionnaires from a sample of 121employees which worked in different functional area. Quantitative methods were applied to analyze data. Chi-square test was used to assess the understanding and practical implementation of Supply chain management practices in Modern Building Industries PLC, while Spearman's correlation and Kruskal Wallis test were used to examine the relationship between supply chain management practices and organizational performance. From the study findings, it showed majority of Modern Building Industries PLC employees not understood the concept of implementing Supply chain management practices. The level of practical implementation was at moderate extent. In addition to organizational performance, the result showed that Supply chain management practices of degree and quality of information sharing and lean practices were positively related to organizational performance in a weak level, while strategic supplier partnership and customer relationship were not related. Finally the researcher made some recommendations for further studies in the field of supply chain management practices implementation.

description: The paper has been prepared for the JETP issue, dedicated to the 95th anniversary of the birth of E.I. Rashba. E. Rashba stood at the origins of macroscopic quantum tunneling together with his colleagues from the Landau Institute S.V. Iordansky and A.M. Finkelshtein. They pave the way for studying macroscopic quantum tunneling in various systems. In this paper, this approach is extended to cosmological objects such as a black hole and de Sitter Universe. In particular, this allowed to calculate the entropy of Reissner-Nordström (RN) black hole with two horizons and the corresponding temperature of the thermal Hawking radiation. Several different approaches were used: the method of semiclassical tunneling for calculation of the Hawking temperature; the cotunneling mechanism -- the coherent sequence of tunneling at two horizons, each determined by the corresponding Hawking temperature; the method of singular coordinate transformations for calculations of macroscopic quantum tunneling from the RN black hole to the RN white hole; the method of the adiabatic change of the fine structure constant for the adiabatic transformation from the RN black hole to the Schwarzschild black hole; etc.

description: Gradient descent (GD) type optimization methods are the standard instrument to train artificial neural networks (ANNs) with rectified linear unit (ReLU) activation. Despite the great success of GD type optimization methods in numerical simulations for the training of ANNs with ReLU activation, it remains - even in the simplest situation of the plain vanilla GD optimization method with random initializations and ANNs with one hidden layer - an open problem to prove (or disprove) the conjecture that the risk of the GD optimization method converges in the training of such ANNs to zero as the width of the ANNs, the number of independent random initializations, and the number of GD steps increase to infinity. In this article we prove this conjecture in the situation where the probability distribution of the input data is equivalent to the continuous uniform distribution on a compact interval, where the probability distributions for the random initializations of the ANN parameters are standard normal distributions, and where the target function under consideration is continuous and piecewise affine linear. Roughly speaking, the key ingredients in our mathematical convergence analysis are (i) to prove that suitable sets of global minima of the risk functions are \emph{twice continuously differentiable submanifolds of the ANN parameter spaces}, (ii) to prove that the Hessians of the risk functions on these sets of global minima satisfy an appropriate \emph{maximal rank condition}, and, thereafter, (iii) to apply the machinery in [Fehrman, B., Gess, B., Jentzen, A., Convergence rates for the stochastic gradient descent method for non-convex objective functions.

description: Interference Alignment (IA) is technique that, in a large sense, makes use of the increasing signal dimensions available in the system through MIMO and OFDM technologies in order to globally reduce the interference suffered by users in a network. In this paper, we address the problem of downlink cellular networks, the so-called interfering broadcast channels, where mobile users at cell edges may suffer from high interference and thus, poor performance. Starting from the downlink IA scheme proposed by Suh et al., a new approach is proposed where each user feeds back multiple selected received signal directions with high signal-to-interference gain. A exhaustive search based scheduler selects a subset of users to be served simultaneously, balancing between sum-rate performance and fairness, but becomes untractable in dense network scenarios where many users send simultaneous requests. Therefore, we develop a sub-optimal scheduler that greatly decreases the complexity while preserving a near-optimal data rate gain. More interestingly, our simulations show that the IA scheme becomes valuable only in correlated channels, whereas the matched filtering based scheme performs the best in the uncorrelated scenarios.
