description: We present an $i$-band photometric study of over 800 young stellar objects in the OB association Cep OB3b, which samples timescales from 1 minute to ten years. Using structure functions we show that on all timescales ($τ$) there is a monotonic decrease in variability from Class I to Class II through the transition disc (TD) systems to Class III, i.e. the more evolved systems are less variable. The Class Is show an approximately power-law increase ($τ^{0.8}$) in variability from timescales of a few minutes to ten years. The Class II, TDs and Class III systems show a qualitatively different behaviour with most showing a power-law increase in variability up to a timescale corresponding to the rotational period of the star, with little additional variability beyond that timescale. However, about a third of the Class IIs show lower overall variability, but their variability is still increasing at 10 years. This behaviour can be explained if all Class IIs have two primary components to their variability. The first is an underlying roughly power-law variability spectrum, which evidence from the infrared suggests is driven by accretion rate changes. The second component is approximately sinusoidal and results from the rotation of the star. We suggest that the systems with dominant longer-timescale variability have a smaller rotational modulation either because they are seen at low inclinations or have more complex magnetic field geometries. We derive a new way of calculating structure functions for large simulated datasets (the "fast structure function"), based on fast Fourier transforms.

description: The reconstruction of Faraday depth structure from incomplete spectral polarization radio measurements using the RM Synthesis technique is an under-constrained problem requiring additional regularisation. In this paper we present cs-romer: a novel object-oriented compressed sensing framework to reconstruct Faraday depth signals from spectro-polarization radio data. Unlike previous compressed sensing applications, this framework is designed to work directly with data that are irregularly sampled in wavelength-squared space and to incorporate multiple forms of compressed sensing regularisation. We demonstrate the framework using simulated data for the VLA telescope under a variety of observing conditions, and we introduce a methodology for identifying the optimal basis function for reconstruction of these data, using an approach that can also be applied to datasets from other telescopes and over different frequency ranges. In this work we show that the delta basis function provides optimal reconstruction for VLA L-band data and we use this basis with observations of the low-mass galaxy cluster Abell 1314 in order to reconstruct the Faraday depth of its constituent cluster galaxies. We use the cs-romer framework to de-rotate the Galactic Faraday depth contribution directly from the wavelength-squared data and to handle the spectral behaviour of different radio sources in a direction-dependent manner. The results of this analysis show that individual galaxies within Abell 1314 deviate from the behaviour expected for a Faraday-thin screen such as the intra-cluster medium and instead suggest that the Faraday rotation exhibited by these galaxies is dominated by their local environments.

description: (Ga,Fe)Sb is a promising ferromagnetic semiconductor for practical spintronic device applications because its Curie temperature ($T_{\rm C}$) is above room temperature. However, the origin of ferromagnetism with high $T_{\rm C}$ remains to be elucidated. Here, we use soft x-ray angle-resolved photoemission spectroscopy (SX-ARPES) to investigate the valence-band (VB) structure of (Ga$_{0.95}$,Fe$_{0.05}$)Sb including the Fe-3$d$ impurity band (IB), to unveil the mechanism of ferromagnetism in (Ga,Fe)Sb. We find that the VB dispersion in (Ga$_{0.95}$,Fe$_{0.05}$)Sb observed by SX-ARPES is similar to that of GaSb, indicating that the doped Fe atoms hardly affect the band dispersion. The Fe-3$d$ resonant ARPES spectra demonstrate that the Fe-3$d$ IB crosses the Fermi level ($E_{\rm F}$) and hybridizes with the VB of GaSb. These observations indicate that the VB structure of (Ga$_{0.95}$,Fe$_{0.05}$)Sb is consistent with that of the IB model which is based on double-exchange interaction between the localized 3$d$ electrons of the magnetic impurities. The results indicate that the ferromagnetism in (Ga,Fe)Sb is formed by the hybridization of the Fe-3$d$ IB with the ligand $p$ band of GaSb.

The wave profiles of the resulting plane waves are given for particular solutions. Abelian and non-abelian T-duality are used as solution generating techniques. Furthermore, it is found that unlike in the case of abelian T-duality, non-abelian T-duality and taking the Penrose limit are not commutative procedures.

description: We investigate the foodborne illness outbreak affecting a national brand of peanut butter to determine how demand for the product category was affected. The illness outbreak coincided with growth in the quantity demanded for the peanut butter category. The negative impact on the category associated with the initiation of the product recall was significant and dissipated over time. The recovery of the product category after the recall indicates that the information was correctly targeted and actions of the companies in the market overcame the initial food scare.

The planar soliton is obtained as a double analytic continuation of the charged black hole metric, which also involves analytically continuing the electric charge. We show that there are phase transitions between both solutions depending on the electric potential, magnetic flux and temperature. The analysis is carried out in the Grand-Canonical ensemble.

Particle-number scaling of the phase sensitivity in realistic Bayesian twin-mode Heisenberg-limited interferometry

description: We investigate the scaling of the phase sensitivity of a nonideal Heisenberg-limited interferometer with the particle number N, in the case of the Bayesian detection procedure proposed by Holland and Burnett [p.r.l. 71, p. 1355 (1993)] for twin boson input modes. Using Monte Carlo simulations for up to 10,000 bosons, we show that the phase error of a nonideal interferometer scales with the Heisenberg limit if the losses are of the order of N^-1. Greater losses degrade the scaling which is then in N^-1/2, like the shot-noise limit, yet the sensitivity stays sub-shot-noise as long as photon correlations are present. These results give the actual limits of Bayesian detection for twin-mode interferometry and prove that it is an experimentally feasible scheme, contrary to what is implied by the coincidence-detection analysis of Kim et al. [p.r.a. 60, p. 708 (1999)].

description: The spins of merging binary black holes offer insights into their formation history. Recently it has been argued that in isolated binary evolution of two massive stars the firstborn black hole is slowly rotating, whilst the progenitor of the second-born black hole can be tidally spun up if the binary is tight enough. Naively, one might therefore expect that only the less massive black hole in merging binaries exhibits non-negligible spin. However, if the mass ratio of the binary is "reversed" (typically during the first mass transfer episode), it is possible for the tidally spun up second-born to become the more massive black hole. We study the properties of such mass-ratio reversed (MRR) binary black hole mergers using a large set of 560 population synthesis models. We find that the more massive black hole is formed second in $\gtrsim 70\%$ of binary black holes observable by LIGO, Virgo, and KAGRA for most model variations we consider, with typical total masses $\gtrsim 20$ M$_{\odot}$ and mass ratios $q = m_2 / m_1 \sim 0.7$ (where $m_1 > m_2$). The formation history of these systems typically involves only stable mass transfer episodes. The second-born black hole has non-negligible spin ($χ> 0.05$) in up to $25\%$ of binary black holes, with among those the more (less) massive black hole spinning in $0\%$--$80\%$ ($20\%$--$100\%$) of cases, varying greatly in our models. We discuss our models in the context of several observed gravitational-wave events and the observed mass ratio - effective spin correlation.

description: Our research addresses the value of information (VOI) for the use of a product's time and temperature history (TTH). Using TTH information, the retailer can set expiration dates dynamically, based on known environmental conditions. This dynamically set expiration date corresponds to the maximum number of periods that inventory may remain available for sale before it must be removed from inventory and discarded (outdated). In current static practice, however, without the availability of TTH, environmental conditions are not known and all units of inventory receive the same expiration date, generally predicated on worst case conditions. Our research demonstrates that information on the TTH as a product flows through the supply chain can be very valuable. Using the example of a supply chain for fresh packaged tomatoes, we quantify the value of TTH information when used for dynamic expiration date setting. We find that the VOI is quite sensitive to environmental and parametric settings, ranging upwards to 90.5% with a mean of 41.2%. Our studies demonstrate that the cost savings that leads to the VOI from TTH and expiration dating stems from two major sources: eliminating the chance of selling perished product, and greatly decreasing the rate at which lost sales occur. In addition, we show that when dynamic expiration dating is used, average product freshness at the time of sale increases significantly. This indicates a win-win situation where costs to the retailer are reduced, and also additional value for the consumer is created. We also extend our analysis into the impact of imperfect information and find that the VOI is fairly robust, up to error levels corresponding to a mean absolute percentage error (MAPE) of approximately 12%. Median VOI at those error levels is 16.5%. The impact of errors, however, differs depending on the model parameterization and we find that under certain settings, the VOI can remain significant for much larger values of MAPE.
title: Fact-checking ecosystem: from modelling to semi-automated stakeholder-based detection of false information
Creators: name: Altuncu, Enes

Year: 2025

description: Humanity has suffered from false, misleading, and malicious information, in short, problematic information, throughout history. Nevertheless, the advances in digital technologies, including the Internet, social media, and smart devices, accelerated and facilitated the dissemination of problematic information. As a complex phenomenon with several aspects to be studied, problematic information remains within many disciplines’ areas of interest. Nevertheless, the lack of a unified understanding of the phenomenon complicates the development of more effective solutions that benefit from multidisciplinary literature to detect problematic information. Focusing on a common type of problematic information, false information, this thesis aims to contribute to filling this gap by presenting a more comprehensive approach to understanding and combating false information. To this end, a topical analysis of the relevant literature was conducted through topic modelling over research publications. This was complemented by the generation of an entity-relationship model of the ecosystem to develop a better conceptual understanding of the landscape and to produce a tool that can be used to guide conceptual analysis of false information-related work and scenarios. Taking a closer look at the proposed model, then, user attitudes and behaviours towards fact-checking tools were examined through an online user survey designed with the help of a new taxonomy of fact-checking tools to collect some empirical evidence for the design of more trustworthy solutions. Most importantly, the conducted survey revealed that semi-automated fact-checking systems, combining human intelligence with automation speed and scalability, can build a higher level of trust among users, compared to manual and fully automated solutions. Therefore, based on the derived conceptual understanding and supported by the obtained empirical evidence, a semi-automated fact-checking tool that is entirely based on expert opinion discovery called aedFaCT was designed, implemented and tested. The presented research in this thesis indicates the potential of semi-automated approaches for the development of more trustworthy and usable fact-checking solutions. The impact of the presented work can be further enhanced by addressing its limitations and incorporating new technological advancements, including large language models (LLMs) and explainable artificial intelligence (xAI).

description: Les recherches sur l'apprentissage coopératif, la métacognition et l'echafaudage changent de plus en plus les approches pédagogiques en enseignement. L'apprentissage de l'orthographe d'usage et grammaticale est encore souvent enseigné de façon magistrale et testé par la dictée hebdomadaire. Cette méthode semble encore satisfaire les parents et élèves mais elle ne démontre pas l'évolution cognitive qu'ont besoin les élèves poour améliorer leur écriture. Danièle Cogis (2005) a fait des recherches extensives sur la dictée modifée, une méthode qui demande à lélève de raisonner ses propres notions à partir d'exercices ciblés dirigés par l'enseignant(e). En utilisant cette méthode d'apprentissage, j'ai voulu voir si mes élèves de septième année d'immersion français pouvaient améliorer leur orthographe d'usage et grammaticale sur une période de dix semaines. Cette méthode s'est avérée plus que je n'anticipais ; la dictée modifée est non seulement un outil pour apprendre plusieurs stratégies utiles pour l'orthographe d'usage et grammaticale, elle est aussi excellente pour apprendre le travail coopératif, la négociation, la métacognition, l'autocorrection et l'autoévaluation. La dictée modifée devient aussi un outil pour l'enseignant(e) dans la mesure qu'il/elle peut cibler ses leçons et identifier les lacunes de ses élèves. Étant donné ces résultats et observations positifs, la dictée modifée fait depuis partie de ma pratique et j'encourage les enseignants autour de moi à l'adopter et à la pratiquer dans leur salle de classe quelque soit leur niveau d'enseignement.

description: We study the integrable structure of the Dirichlet boundary problem in two dimensions and extend the approach to the case of planar multiply-connected domains. The solution to the Dirichlet boundary problem in multiply-connected case is given through a quasiclassical tau-function, which generalizes the tau-function of the dispersionless Toda hierarchy. It is shown to obey an infinite hierarchy of Hirota-like equations which directly follow from properties of the Dirichlet Green function and from the Fay identities. The relation to multi-support solutions of matrix models is briefly discussed.

description: We revisit the Scalar Weak Gravity Conjecture and investigate the possibility to impose that scalar interactions dominate over gravitational ones. More precisely, we look for consequences of assuming that, for leading scalar interactions, the corresponding gravitational contribution is sub-dominant in the non-relativistic limit. For a single massive scalar particle, this leads us to compare four-point self-interactions in different type of potentials. For axion-like particles, we retrieve the result of the Axion Weak Gravity Conjecture: the decay constant $f$ is bounded by the Planck mass, $f < {M_{Pl}}$. Similar bounds are obtained for exponential potentials. For quartic, power law and Starobinsky potentials, we exclude large trans-Planckian field excursions. We then discuss the case of moduli that determine the scalars masses. We retrieve the exponential dependence as requested by the Swampland Distance Conjecture. We also find extremal state masses with field dependence that reproduces both the Kaluza-Klein and winding modes behaviour. In particular cases, our constraints can be put in the form of the Refined de Sitter Conjecture.

description: The detection of double black hole (BH+BH) mergers provides a unique possibility to understand their physical properties and origin. To date, the LIGO-Virgo-KAGRA network of high-frequency gravitational wave observatories have announced the detection of more than 85 BH+BH merger events (Abbott et al. 2022a). An important diagnostic feature that can be extracted from the data is the distribution of effective inspiral spins of the BHs. This distribution is in clear tension with theoretical expectations from both an isolated binary star origin, which traditionally predicts close-to aligned BH component spins (Kalogera 2000; Farr et al. 2017), and formation via dynamical interactions in dense stellar environments that predicts a symmetric distribution of effective inspiral spins (Mandel & O'Shaughnessy 2010; Rodriguez et al. 2016b). Here it is demonstrated that isolated binary evolution can convincingly explain the observed data if BHs have their spin axis tossed during their formation process in the core collapse of a massive star, similarly to the process evidently acting in newborn neutron stars. BH formation without spin-axis tossing, however, has difficulties reproducing the observed data - even if alignment of spins prior to the second core collapse is disregarded. Based on simulations with only a minimum of assumptions, constrains from empirical data can be made on the spin magnitudes of the first- and second-born BHs, thereby serving to better understand massive binary star evolution prior to the formation of BHs.

description: A policy debate on widespread currency manipulation has generated economic analyses to inform policymakers regarding both the extent and impact of the problem. Such analyses typically focus on commodity trade and price impacts while ignoring potentially important supply chain linkages. Using Chinese exchange rate policy and global soybean and soybean product markets as an example, this paper illustrates that substantial measurement errors are possible if supply chain linkages are ignored in exchange rate policy analyses. As a consequence, policy responses to foreign currency manipulation informed by such analyses may be misguided or imprecise at best.

Magnetic activity in late-type giant stars: Numerical MHD simulations of non-linear dynamo action in Betelgeuse

description: Evidence is presented from numerical magneto-hydrodynamical simulations for the existence of magnetic activity in late-type giant stars. A red supergiant with stellar parameters similar to that of Betelgeuse (alpha Orionis) is modeled as a "star-in-a-box" with the high-order "Pencil Code". Both linear kinematic and non-linear saturated dynamo action are found: the non-linear magnetic field saturates at a super-equipartition value (a factor two above equipartition yielding surface fields with strengths on the order of 500 Gauss), while in the linear regime two different modes of dynamo action are found. It is speculated that magnetic activity of late-type giants may influence dust and wind formation and possibly lead to the heating of the outer atmospheres of these stars.

description: Measuring a pulsar's rotational evolution is crucial to understanding the nature of the pulsar. Here we provide updated timing models for the rotational evolution of six pulsars, five of which are rotation phase-connected using primarily NICER X-ray data. For the newly-discovered fast energetic young pulsar, PSR J0058-7218, we increase the baseline of its timing model from 1.4 days to 8 months and not only measure more precisely its spin-down rate nudot = (-6.2324+/-0.0001)x10^-11 Hz s^-1 but also for the first time the second time derivative of spin rate nuddot = (4.2+/-0.2)x10^-21 Hz s^-2. For the fastest and most energetic young pulsar, PSR J0537-6910 (with 16 ms spin period), we detect 4 more glitches, for a total of 15 glitches over 4.5 years of NICER monitoring, and show that its spin-down behavior continues to set this pulsar apart from all others, including a long-term braking index n = -1.234+/-0.009 and interglitch braking indices that asymptote to <~ 7 for long times after a glitch. For PSR J1101-6101, we measure a much more accurate spin-down rate that agrees with a previous value measured without phase-connection. For PSR J1412+7922 (also known as Calvera), we extend the baseline of its timing model from our previous 1-year model to 4.4 years, and for PSR J1849-0001, we extend the baseline from 1.5 years to 4.7 years. We also present a long-term timing model of the energetic pulsar, PSR J1813-1749, by fitting previous radio and X-ray spin frequencies from 2009-2019 and new ones measured here using 2018 NuSTAR and 2021 Chandra data.

description: Abstract

There are benefits and drawbacks to relying only on social media for news updates. It is true that social media platforms facilitate the rapid dissemination of knowledge among individuals. Still, these kinds of websites might be used to spread misinformation-filled, low-quality content—what is known as "fake news." Because malevolent actors may sway readers with misinformation and false news, social media has grown into an integral part of state security, generating needless discussion on matters that are inherently meaningless to society. This leads to a domino effect, public anxiety, and ultimately risks to the security of the state. Early fake news detection is the most important step in saving people's lives from the spread of false information. People unintentionally contribute to the spread of false information by spreading it. Thus, identifying fake news that has been posted on different social media platforms has recently gained a lot of attention as a developing field of study. The detection of false news on the many social media platforms presents new difficulties that render the algorithms now in use obsolete or inefficient. On the other hand, the original propagators of false news seek to disseminate the misinformation by focusing on innocent individuals. Cutting-edge data sensors and deep learning methods hold considerable promise for facilitating the development of useful solutions to address the issue of false news. However, because of data shortages, such remedies often need improved model generalisation in the actual world. In this research, we address the problem of false news identification by introducing a novel approach that uses a committee of classifiers. Neuronal networks have shown to be an excellent tool among others for identifying bogus news on social media. In this study, a deep learning-based methodology has been used to distinguish bogus news from authentic sources. The suggested model has been constructed using an LSTM neural network. To that purpose, we provide a variety of basic models, each of which has been individually trained on sub-corpora with distinct qualities. Specifically, we use multi-label text-type categorization to aid in the formation of an ensemble. The study was carried out using six distinct benchmark datasets. The findings are encouraging and pave the way for more study.

description: A novel mechanical approach is developed to explore by means of atom-scale simulation the concept of line tension at a solid-liquid-vapor contact line as well as its dependence on temperature, confinement, and solid/fluid interactions. More precisely, by estimating the stresses exerted along and normal to a straight contact line formed within a partially wet pore, the line tension can be estimated while avoiding the pitfalls inherent to the geometrical scaling methodology based on hemispherical drops. The line tension for Lennard-Jones fluids is found to follow a generic behavior with temperature and chemical potential effects that are all included in a simple contact angle parameterization. Former discrepancies between theoretical modeling and molecular simulation are resolved, and the line tension concept is shown to be robust down to molecular confinements. The same qualitative behavior is observed for water but the line tension at the wetting transition diverges or converges towards a finite value depending on the range of the solid/fluid interactions at play.

description: We address the problem of how to set expiration dates for perishable products in the context of a re- tailer that sells a random lifetime product under periodic review. Although the lifetime is random, the retailer, in addition to deciding when and how much to order, must also determine an expiration date that corresponds to the maximum number of periods that inventory may remain available for sale before it must be discarded. Unlike other models of perishable inventory, but similar to real-world processes, it is possible to unknowingly sell products that have reached the limit of their retail shelf life, or to discard products that are still good for sale. As a result, retailers must balance hazard costs and perishing costs by setting a remaining shelf life that provides customers with a reasonable time for storage at home before the product actually spoils. We formulate the problem as a Markov Decision Process and also introduce two heuristic policies for the computation of order quantities and expiration dates that are of more practical relevance. We conduct an extensive simulation study, focusing on fresh packaged tomatoes as an illustrative example. Through this study, we evaluate the sensitivity of the computed expiration dates relative to the problem parameters and provide managerial insight into the role of expiration date setting for inventory control. ©2017 Elsevier B.V.

The Conformational Space of a Flexible Amino Acid at Metallic Surfaces

description: In interfaces between inorganic and biological materials relevant for technological applications, the general challenge of structure determination is exacerbated by the high flexibility of bioorganic components, chemical bonding, and charge rearrangement at the interface. In this paper, we investigate a chemically complex building block, namely, the arginine (Arg) amino-acid interfaced with Cu, Ag and Au (111) surfaces. We investigate how the environment changes the accessible conformational space of this amino acid, by building and analyzing a database of thousands of structures optimized with the PBE functional including screened pairwise van der Waals interactions. When in contact with metallic surfaces, the accessible space for Arg is dramatically reduced, while the one for Arg-H$^+$ is instead increased if compared to the gas-phase. This is explained by the formation of strong bonds between Arg and the surfaces and by their absence and charge screening on Arg-H$^+$ upon adsorption. We also observe protonation-dependent stereoselective binding of the amino acid to the metal surfaces: Arg adsorbs with its chiral C$_α$H center pointing H away from the surfaces while Arg-H$^+$ adsorbs with H pointing toward the surface.

description: The food environment in the United States is complex. Sixteen socio-economic-demographic variables from various public data sources are studied with a machine learning algorithm to ascertain the causality structure associated with the food environment in the United States. High levels of unemployment and poverty are direct causes of high levels of food insecurity, while low income causes high levels of food insecurity via increased levels of poverty. Unemployment is a common cause for both increased levels of food insecurity and poverty. We find that food insecurity and participation in Supplemental Nutrition Assistance Program (SNAP) are related, yet no direct causality is observed. Contrary to past studies which find that SNAP participation decreased the occurrences of poverty, in contemporaneous time, we find that poverty and SNAP participation are related through several back-door paths, via food insecurity, unemployment, race and food taxes. Obesity and SNAP participation are indirectly related via several back-door paths, namely, race income, poverty and food insecurity and unemployment. Also, food insecurity and obesity are related by several back-door paths. Low income, high food taxes, and race (being Black and non-Hispanic) are direct causes of obesity. The complex causality structure in the US food environment reveals that policy variables cannot be treated independently of their rich causal structure. Government agencies responsible for designing policies for food assistance, poverty alleviation, combating food insecurity and obesity need to consider the interrelationships among these variables.
