description: We consider quantum gravity fluctuations in a pair of nearby gravitational wave detectors. Quantum fluctuations of long-wavelength modes of the gravitational field induce coherent fluctuations in the detectors, leading to correlated noise. We determine the variance and covariance in the lengths of the arms of the detectors, and thereby obtain the graviton noise correlation. We find that the correlation depends on the angle between the detector arms as well as their separation distance. Using our result, we propose an experimental setup to detect this noise. The suggested interferometer configuration can be used to distinguish quantum-gravitational noise from both correlated and uncorrelated sources of background noise.

description: Covid-19 has had a big impact on many aspects of our life, including mental health. Since the start of the pandemic, a whole body of Belgian research has been performed on the relation between covid-19 and mental health (care). The mental health & covid-19 working group of the superior health council lists these studies in order to provide advice to policy makers and the general public. The first advisory report focused on international literature on contagious outbreaks, since not many studies on covid-19 and, especially, not many Belgian studies were published yet. This advice can be found here: https://www.health.belgium.be/en/report-9589-mental-health-and-covid-19 As part of the work performed in the first advisory report, the Policy Coordination Working group has asked the Superior Health Council to list all Belgian studies investigating the relation between covid-19 and mental health and/or mental health care and to provide regular updates. The superior Health Council, therefore, started the project of the Belgian mental health data repository. This repository will consist of ongoing studies, preliminary results, accepted and published articles with a Belgian population. For each study, an overview will be given of the authors (including contact details), level of evidence and a short description of the study. The Belgian Mental Health Data Repository will allow for other researchers, policy makers, health care providers and the general public to have a better idea of and easier access to the mental health studies in Belgium. Additionally, more in-depth analyses across studies can be facilitated leading to better insights into the impact of covid-19 on mental health. An update of the living document will be published weekly. Below the third update of the living document can be found.

description: A quantum field theory is described which is a supersymmetric classical model. -- Supersymmetry generators of the system are used to split its Liouville operator into two contributions, with positive and negative spectrum, respectively. The unstable negative part is eliminated by a positivity constraint on physical states, which is invariant under the classical Hamiltonian flow. In this way, the classical Liouville equation becomes a functional Schroedinger equation of a genuine quantum field theory. Thus, 't Hooft's proposal to reconstruct quantum theory as emergent from an underlying deterministic system, is realized here for a field theory. Quantization is intimately related to the constraint, which selects the part of Hilbert space where the Hamilton operator is positive. This is seen as dynamical symmetry breaking in a suitably extended model, depending on a mass scale which discriminates classical dynamics beneath from emergent quantum mechanical behaviour.

description: We compute the suppression and elliptic flow of bottomonium using real-time solutions to the Schrödinger equation with a realistic in-medium complex-valued potential. To model the initial production, we assume that, in the limit of heavy quark masses, the wave-function can be described by a lattice-smeared (Gaussian) Dirac delta wave-function. The resulting final-state quantum-mechanical overlaps provide the survival probability of all bottomonium eigenstates. Our results are in good agreement with available data for $R_{AA}$ as a function of $N_{\rm part}$ and $p_T$ collected at $\sqrt{s_{\rm NN}} =$ 5.02 TeV. In the case of $v_2$ for the various states, we find that the path-length dependence of $Υ(1s)$ suppression results in quite small $v_2$ for $Υ(1s)$. Our prediction for the integrated elliptic flow for $Υ(1s)$ in the $10{-}90$% centrality class is $v_2[Υ(1s)] = 0.0026 \pm 0.0007$. We additionally find that, due to their increased suppression, excited bottomonium states have a larger elliptic flow and we make predictions for $v_2[Υ(2s)]$ and $v_2[Υ(3s)]$ as a function of centrality and transverse momentum. Similar to prior studies, we find that it is possible for bottomonium states to have negative $v_2$ at low transverse momentum.

Subjects: Research Methods/ Statistical Methods

description: This article reviews some of the recent methodology developed for the analysis of time series data stressing that the statistical properties of the individual series need to be analysed to avoid spurious regressions. A convergence of econometric methodology is entertained with specific focus on cointegration and error correction models which allows the testing of long run relationships between variables and allows for a more dynamic structure than some of the previous models that appear in the literature. An example of this is the commonly used partial adjustment model in supply analysis which is nested in the less restrictive error correction model. Tests can be performed on the validity of these restrictions. These models have a wide application in agricultural economic analysis.
Emergent AdS-like Boundaries from Recursive Coherence Collapse
Creators: name: Thavarajah, Rogan
Publisher: name: Zenodo
Year: 2025

description: This work introduces and proves the Recursive Incompleteness Theorem, which extends Gödel’s incompleteness results by formalizing a recursive mechanism through which unprovable truths in a formal system become provable in its computable extensions. Rather than attempting to bypass or resolve Gödel's incompleteness within a single system, this theorem reinterprets incompleteness as a dynamic, recursive structure—where each system layer absorbs and extends the limitations of its predecessor.

Built on four core axioms—recursive extension, phase-dependent truth, constructive self-reference, and asymptotic incompleteness—the framework establishes a computable sequence of formal systems {Ft}\{\mathcal{F}_t\}{Ft}, where each extension Ft+1\mathcal{F}_{t+1}Ft+1 coherently integrates previously unreachable truths. This recursive unfolding models truth as an emergent phenomenon across logical time, offering a unified view that bridges mathematical logic, recursion theory, epistemology.

This theorem is supported by a formal proof, philosophical analysis, and reflections on its implications for computation, consciousness, and moral reasoning.

description: Marker code is an effective coding scheme to protect data from insertions and deletions. It has potential applications in future storage systems, such as DNA storage and racetrack memory. When decoding marker codes, perfect channel state information (CSI), i.e., insertion and deletion probabilities, are required to detect insertion and deletion errors. Sometimes, the perfect CSI is not easy to obtain or the accurate channel model is unknown. Therefore, it is deserved to develop detecting algorithms for marker code without the knowledge of perfect CSI. In this paper, we propose two CSI-agnostic detecting algorithms for marker code based on deep learning. The first one is a model-driven deep learning method, which deep unfolds the original iterative detecting algorithm of marker code. In this method, CSI become weights in neural networks and these weights can be learned from training data. The second one is a data-driven method which is an end-to-end system based on the deep bidirectional gated recurrent unit network. Simulation results show that error performances of the proposed methods are significantly better than that of the original detection algorithm with CSI uncertainty. Furthermore, the proposed data-driven method exhibits better error performances than other methods for unknown channel models.

description: Market-based environmental policies have been forwarded as alternatives to current pollution control policies. Implementation of the "polluter pays" principle and governmental enforcement of pollution clean-up have led to astronomical environmental liabilities and clean-up costs, which may threaten the survival of many productive ventures, unless producers can spread pollution risk through insurance. An emission constrained target MOTAD LP (TMLP) model showed that pollution insurance for irrigation farmers can be a feasible and efficient solution to agricultural salinization problems in the Loskop Valley, and fairly low salinity standards with pollution insurance will still be reconcilable with profitable farming. Pollution insurance appears to hold promise for applying the "polluter pays" principles also to non-point pollution. Site specific studies are needed for pollution policy, and more research is needed on pollution standards.

description: High spectral resolution transmission spectroscopy is a powerful tool to characterize exoplanet atmospheres. Especially for hot Jupiters, this technique is highly relevant, due to their high altitude absorption e.g. from resonant sodium (Na I) and potassium (K I) lines. We resolve the atmospheric K I-absorption on HD189733b with the aim to compare the resolved K I -line and previously obtained high resolution Na I-D-line observations with synthetic transmission spectra. The line profiles suggest atmospheric processes leading to a line broadening of the order of 10 km/s for the Na I-D-lines, and only a few km/s for the K I-line. The investigation hints that either the atmosphere of HD189733b lacks a significant amount of K I or the alkali lines probe different atmospheric regions with different temperature, which could explain the differences we see in the resolved absorption lines.

Risk and Uncertainty

description: This study analyses the importance and dimensions of risk sources and computer adoption among farmers in a changing economic policy and trade environment. A survey was conducted in 1996 among 112 commercial farmers in KwaZulu-Natal. The majority of respondents were in favour of a liberalized trade environment and deregulated domestic product and input markets. Respondents identified changes in the cost of farm inputs, government legislation (tax, labour, and land redistribution), the Rand exchange rate, and product prices as the most important sources of risk. Factor analysis of risk sources showed that various dimensions to risk exist, including changes in government policy, enterprise gross income, credit access and cost changes. Computers, a risk management tool, are more likely to be adopted by larger farm operators who have higher levels of education and who use more information sources, whilst operators of extensive production systems are less likely to adopt computers.
Constructing word/world knowledge together : young children’s emerging understandings of/with informational texts
Creators: name: Filipenko, Margot Jessica
Publisher: name: University of British Columbia
Year: 2009

description: Although young children's developing understandings of the concept of story have been thoroughly researched, children's informational literacy development has gone largely unexamined. This descriptive, naturalistic study in an emergent-literacy preschool classroom investigated what young children's talk revealed about their understandings of informational texts and the ways in which their teacher enabled and scaffolded those understandings. Over a 3-month period children's responses were videotaped in five contexts: full and small group readalouds, full and small group activities incorporating informational texts and child-to-child informational text sharing. Other data included observational field notes and an interview with the focus teacher. Data (observational field notes and selective transcriptions or complete transcriptions) were collected on a total of 45 episodes of children engaging with informational texts. From this data set, 19 transcripts (2 full group readalouds, 6 small group readalouds, 5 full group activities incorporating informational texts, 3 small group activities incorporating informational texts, and 3 child-to-child sharing of informational texts) were chosen for coding and in-depth analysis. The other data were used in a supplementary way. Six broad conceptual categories of children's talk emerged from the data analysis: informational text knowledge; world knowledge; representing meaning; building connections; reflective talk, and relational talk. These categories represented the various facets of children's engagement with informational texts and revealed the ways in which these children constructed meaning about and with informational texts. The teacher scaffolded the children's emerging understandings of informational texts by taking the roles of: recruiter (orienting and recruiting the children to the text); director (directing the children's attention to particular features of the text); model (modelling the reading process); elaborator (providing elaborative feedback); connector (making life-to-text and text-to-life connections); provocateur (prodding children to think more deeply about a topic); and conductor (facilitating the day-to-day routines of a classroom community). Individual styles of engagement with informational texts were identified and explored for two of the children. A grounded theory of young children's informational literacy development was developed that proposes: Young children's informational literacy development consists of six aspects: informational text knowledge, world knowledge, representation, reflection, connections and relational talk. During an informational literacy event these six aspects dynamically engage and blur as the child works to construct meaning. Informational literacy development is the dynamic process whereby this engagement results in a transformational moment.

description: We discuss Hamiltonian learning in quantum field theories as a protocol for systematically extracting the operator content and coupling constants of effective field theory Hamiltonians from experimental data. Learning the Hamiltonian for varying spatial measurement resolutions gives access to field theories at different energy scales, and allows to learn a flow of Hamiltonians reminiscent of the renormalization group. Our method, which we demonstrate in both theoretical studies and available data from a quantum gas experiment, promises new ways of addressing the emergence of quantum field theories in quantum simulation experiments.

On the generation of asymmetric warps in disk galaxies
Creators: name: Saha, Kanak
name: Jog, Chanda J.
Publisher: name: arXiv
Year: 2005
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: The warps in many spiral galaxies are now known to asymmetric. Recent sensitive observations have revealed that asymmetry of warps may be the norm rather than exception. However there exists no generic mechanism to generate these asymmetries in warps. We have derived the dispersion relation in a compact form for the S-shaped warps(described by the m=1 mode) and the bowl-shaped distribution(described by the m=0 mode) in galactic disk embedded in a dark matter halo. We then performed the numerical modal analysis and used the linear and time-dependent superposition principle to generate asymmetric warps in the disk. On doing the modal analysis we find the frequency of the $m=0$ mode is much larger than that of the $m=1$ mode. The linear and time-dependent superposition of these modes with their unmodulated amplitudes(that is, the coefficients of superposition being unity) results in an asymmetry in warps of ~ 20 - 40 %, whereas a smaller coefficient for the m=0 mode results in a smaller asymmetry. The resulting values agree well with the recent observations. We study the dependence of the asymmetry index on the dark matter halo parameters. This approach can also naturally produce U-shaped warps and L-shaped warps. We show that a rich variety of possible asymmetries in the z-distribution of the spiral galaxies can naturally arise due to a dynamical wave interference between the first two bending modes(i.e. m=0 and m=1) in the disk. This is a simple but general method for generating asymmetric warps that is independent of how the individual modes arise in the disk.

description: Optimum management strategies (crop rotation systems, crop areas, irrigation intensities and moveable capital replacement) for typical one, two and three plot farmers at Vaalharts were determined under different intensities and incidences of water limitations as well as with increased water quotas and peak canal deliverances. Special consideration was given to changes needed in management strategy as well as the ability of the different typical farmers to survive financially as availability of water changes. The study utilised, inter alia, dynamic linear programming, water production functions and loss functions. The results indicate significant changes in optimum management strategies as water limitations, water quotas and peak canal deliverance change. The ability to replace moveable capital differs considerably among the different typical farm units.
Dynamical taxonomy of the coupled solar radiation pressure and oblateness problem and analytical deorbiting configurations

description: Recent works demonstrated that the dynamics caused by the planetary oblateness coupled with the solar radiation pressure can be described through a model based on singly-averaged equations of motion. The coupled perturbations affect the evolution of the eccentricity, inclination and orientation of the orbit with respect to the Sun--Earth line. Resonant interactions lead to non-trivial orbital evolution that can be exploited in mission design. Moreover, the dynamics in the vicinity of each resonance can be analytically described by a resonant model that provides the location of the central and hyperbolic invariant manifolds which drive the phase space evolution. The classical tools of the dynamical systems theory can be applied to perform a preliminary mission analysis for practical applications. On this basis, in this work we provide a detailed derivation of the resonant dynamics, also in non-singular variables, and discuss its properties, by studying the main bifurcation phenomena associated to each resonance. Last, the analytical model will provide a simple analytical expression to obtain the area-to-mass ratio required for a satellite to deorbit from a given altitude in a feasible timescale.

description: The Southern African Region is facing formidable economic challenges on issues such as poverty reduction, food security, employment creation, increased farm productivity, the sustainable use of natural resources, land reform and human capital development. To meet these challenges it is argued in this article that the agricultural sector should perform a essential role in the generation of rural incomes, employment and food security and also to transfer resources efficiently to other sectors of the regional economy. However, this sector is not fully utilized yet in the different countries of the region. The nature of this role will also differ between countries.

description: The energetic efficiency of an overdamped Brownian particle in a saw tooth potential in the presence of time asymmetric forcing is studied in the adiabatic limit. An error made in the earlier work on the same problem in literature is corrected. We find that asymmetry in potential together with temporal asymmetry in forcing leads to much enhanced efficiency without fine tuning of parameters. The origin of this is traced to the suppression of backward current. We also present a comparative study between the role of continuous and discontinuous ratchet forces on these measurable quantities. We find that the thermal fluctuations can optimize the energy transduction, the range of parameters, however, being very small. This ratchet model also displays current reversals on tuning of parameters even in the adiabatic regime. The possible relationships between nature of currents, entropy production and input energy are also addressed.

description: We present a complete classification of invariant generalised Killing spinors on three-dimensional Lie groups. We show that, in this context, the existence of a non-trivial invariant generalised Killing spinor implies that all invariant spinors are generalised Killing with the same endomorphism. Notably, this classification is independent of the choice of left-invariant metric. To illustrate the computational methods underlying this classification, we also provide the first known examples of homogeneous manifolds admitting invariant generalised Killing spinors with $n$ distinct eigenvalues for each $n > 4$.

description: Although measuring held-out accuracy has been the primary approach to evaluate generalization, it often overestimates the performance of NLP models, while alternative approaches for evaluating models either focus on individual tasks or on specific behaviors. Inspired by principles of behavioral testing in software engineering, we introduce CheckList, a task-agnostic methodology for testing NLP models. CheckList includes a matrix of general linguistic capabilities and test types that facilitate comprehensive test ideation, as well as a software tool to generate a large and diverse number of test cases quickly. We illustrate the utility of CheckList with tests for three tasks, identifying critical failures in both commercial and state-of-art models. In a user study, a team responsible for a commercial sentiment analysis model found new and actionable bugs in an extensively tested model. In another user study, NLP practitioners with CheckList created twice as many tests, and found almost three times as many bugs as users without it.

description: It is generally agreed that increasing agricultural productivity is critical to stimulating the rate of economic growth in Africa. There are many important and often complementary determinants of agricultural productivity. In this paper, we focus on fertilizer, without intending to imply that it is the only or most significant productivity determinants. Other key factors are seed technology, adequate water availability, labor, agronomic and other farmer management practices, and choice of crops to grow.

description: We consider the stochastic Swift-Hohenberg equation on a large domain near its change of stability. We show that, under the appropriate scaling, its solutions can be approximated by a periodic wave, which is modulated by the solutions to a stochastic Ginzburg-Landau equation. We then proceed to show that this approximation also extends to the invariant measures of these equations.

description: We estimate adults’ willingness to pay (WTP) to reduce health risks to their own or other families’ infants to test for altruism. A conjoint analysis of adults paying for bottled water found marginal WTP for reduction in risk of shock, brain damage, and mortality in the cash treatment of $2, $3.70, and $9.43, respectively. In the hypothetical market these amounts were $14, $26, and $66, indicating substantial hypothetical bias, although not unexpected due to the topic of infant health. Statistical tests confirm a high degree of altruism in our WTP results, and altruism held even when real money was involved.

description: High-dimensional expanders are a generalization of the notion of expander graphs to simplicial complexes and give rise to a variety of applications in computer science and other fields. We provide a general tool to construct families of bounded degree high-dimensional spectral expanders. Inspired by the work of Kaufman and Oppenheim, we use coset complexes over quotients of Kac-Moody-Steinberg groups of rank $d+1$, $d$-spherical and purely $d$-spherical. We prove that infinite families of such quotients exist provided that the underlying field is of size at least 4 and the Kac-Moody-Steinberg group is 2-spherical, giving rise to new families of bounded degree high-dimensional expanders. In the case the generalized Cartan matrix we consider is affine, we recover the construction of O'Donnell and Pratt from 2022, (and thus also the one of Kaufman and Oppenheim) by considering Chevalley groups as quotients of affine Kac-Moody-Steinberg groups. Moreover, our construction applies to the case where the root system is of type $\tilde{G}_2$, a case that was not covered in earlier works.

description: We holographically investigate the scalarization in the Einstein-Scalar-Gauss-Bonnet gravity with a negative cosmological constant. We find that instability exists for both Schwarzschild-AdS and Reissner-Nordstrom-AdS black holes with planar horizons when we have proper interactions between the scalar field and the Gauss-Bonnet curvature corrections. We relate such instability to possible holographic scalarization and construct the corresponding hairy black hole solutions in the presence of the cosmological constant. Employing the holographic principle we expect that such bulk scalarization corresponds to the boundary description of the scalar hair condensation without breaking any symmetry, and we calculate the related holographic entanglement entropy of the system. Moreover, we compare the mechanisms of the holographic scalarizations caused by the effect of the coupling of the scalar field to the Gauss-Bonnet term and holographic superconductor effect in the presence of an electromagnetic field, and unveil their differences in the effective mass of the scalar field, the temperature dependent property and the optical conductivity.

description: The production of $^{3}$H, $^{7}$Be, and $^{22}$Na by interactions of cosmic-ray particles with silicon can produce radioactive backgrounds in detectors used to search for rare events. Through controlled irradiation of silicon CCDs and wafers with a neutron beam that mimics the cosmic-ray neutron spectrum, followed by direct counting, we determined that the production rate from cosmic-ray neutrons at sea level is ($112 \pm 24$) atoms/(kg day) for $^{3}$H, ($8.1 \pm 1.9 $) atoms/(kg day) for $^{7}$Be, and ($43.0 \pm 7.1 $) atoms/(kg day) for $^{22}$Na. Complementing these results with the current best estimates of activation cross sections for cosmic-ray particles other than neutrons, we obtain a total sea-level cosmic-ray production rate of ($124 \pm 24$) atoms/(kg day) for $^{3}$H, ($9.4 \pm 2.0 $) atoms/(kg day) for $^{7}$Be, and ($49.6 \pm 7.3 $) atoms/(kg day) for $^{22}$Na. These measurements will help constrain background estimates and determine the maximum time that silicon-based detectors can remain unshielded during detector fabrication before cosmogenic backgrounds impact the sensitivity of next-generation rare-event searches.

description: Animal welfare concerns are having dramatic impacts on food and livestock markets. Here we examine consumer preferences for pork products with a focus on use of gestation crates. We examine underlying consumer valuations of pork attributes while considering preference heterogeneity as well as voluntary and legislative alternatives in producing gestation crate-free pork. Our results suggest that prohibiting swine producers from using gestation crates fails to improve consumer welfare in the presence of a labeling scheme documenting voluntary disadoption of gestation crates. Consumers are found to implicitly associate animal welfare attributes with smaller farms. Preference heterogeneity drives notably diverse consumer welfare impacts when pork produced with use of gestation crates is no longer available for consumption.
