description: X-ray observations of the optically selected $z=6.025$ QSO CFHQS J164121+375520 (hereafter J1641) revealed that its flux dropped by a factor $\gtrsim7$ from 2018, when it was a bright and soft X-ray source, to 2021. Such a strong variability amplitude has not been observed before among $z>6$ QSOs, and the underlying physical mechanism was unclear. We carried out a new X-ray and rest-frame UV monitoring campaign of J1641 over 2022-2024. We detected J1641 with Chandra in the 2-7 keV band, while no significant emission is detected at softer X-ray energies, making J1641 an X-ray changing look QSO at $z>6$. Comparing with the 2018 epoch, the 0.5-2 keV flux dropped dramatically by a factor $>20$. We ascribe this behaviour to intervening, and still ongoing, obscuration by Compton-thick gas intercepting our line of sight between 2018 and 2021. The screening material could be an inner disk or a failed nuclear wind that increased their thickness. Another possibility is that we have witnessed an occultation event due to dust-free clouds located at sub-pc/pc scales, similar to those recently invoked to explain the remarkable X-ray weakness of AGN discovered by JWST. These interpretations are also consistent with the lack of strong variations of the QSO rest-frame UV lightcurve over the same period. Future monitoring of J1641 and the possible discovery of other X-ray changing look QSOs at $z>6$ will provide us with precious information about the physics of rapid supermassive black-hole growth at high redshift.

description: Context. Solar filament oscillations have been observed for many years, but recent advances in telescope capabilities now enable daily monitoring of these periodic motions, offering valuable insights into the structure of filaments. A systematic study of filament oscillations over the solar cycle can shed light on the evolution of the prominences. Until now, only manual techniques have been used to analyze these oscillations.
 Aims. This work serves as a proof of concept, aiming to demonstrate the effectiveness of Convolutional Neural Networks (CNNs). These networks automatically detect filament oscillations by applying power-spectrum analysis to H$α$ data from the GONG telescope network.
 Methods. The proposed technique studies periodic fluctuations of every pixel of the H$α$ data cubes. Using the Lomb Scargle periodogram, we computed the power spectral density (PSD) of the dataset. The background noise is well fitted to a combination of red and white noise. Using Bayesian statistics and Markov chains -- Monte Carlo (MCMC) algorithms we can fit the spectra and determine the confidence threshold of a given percentage to search for real oscillations. We built two CNN models to obtain the same results as the MCMC approach.
 Results. We applied the CNN models to some observations reported in the literature, proving its reliability in detecting the same events as the classical methods. A day with events not previously reported has been studied to check for the model capabilities outside of a controlled dataset where we can check with previous reports.
 Conclusions. CNNs proved to be a useful tool to study solar filament oscillations, using spectral techniques. Computing times have been reduced significantly while getting results similar enough to the classical methods. This is a relevant step towards the automatic detection of filament oscillations.
On the Reality of the Accelerating Universe

description: Two groups recently deduced the positive value for the cosmological constant, concluding at a high (>= 99%) confidence level that the Universe should be accelerating. This conclusion followed from the statistical analysis of dozens of high-redshift supernovae. In this paper this conclusion is discussed. From the conservative frequentist's point of view the validity of null hypothesis of the zero cosmological constant is tested by the classical statistical chi^2 test for the 60 supernovae listed in Perlmutter et al. 1999 (ApJ, 517, 565). This sample contains 42 objects discovered in the frame of Supernova Cosmology Project and 18 low-redshift object detected earlier. Excluding the event SN1997O, which is doubtlessly an outlier, one obtains the result: The probability for seeing a worse chi^2 - if the null hypothesis is true - is in the 5% to 8% range, a value that does not indicate significant evidence againts the null. If one excludes further five possible outliers, proposed to be done by Perlmutter et al. 1999, then the sample of 54 supernovae is in an excellent accordance with the null hypothesis. It also seems that upernovae from the High-z Supernova Search Team does not change the acceptance of null hypothesis. This means that the rejection of the Einstein equations with zero cosmological constant - based on the supernova data alone - is still premature.

Behavioural factors influencing adult participation in Massive Open Online Courses
Creators: name: Panicker, Parvathy
Publisher: name: Zenodo
Year: 2021

description: Educational technology involves the integration of technologies and media in instructional contexts and includes integrating media into instructional processes to enhance the teaching-learning process. Massive Open Online Courses (MOOC) are a commonly used online platform for education and delivers courses using educational technology. MOOCs are intended to be â€˜openâ€™, i.e. free and unrestricted access involving no face-to-face contact, time-sensitive and includes an assessment model along with accreditation. In the context of delivering courses through MOOCs in the higher education sector, several contextual challenges can undermine the adoption and retention of educational technology. Different psychological constructs that define the key stakeholders (e.g., students, teachers, mentors and work colleagues), namely the Dualistic Model of Passion (DMP), which includes Harmonious Passion (HP), Obsessive Passion (OP) and Perseverance of Effort (PoE), are often ignored when technology acceptance and usage are assessed. Furthermore, assumptions are made regarding levels of self-motivation of participants undertaking the online course and it is presumed that the personâ€™s behaviour is not influenced by other people who are close to them. The Technology Acceptance Model (TAM) will be used to evaluate the relationship between motivation, subjective norm and technology usage. Though motivation is defined in terms of dualistic model of passion and perseverance of effort, their relationship with subjective norm have not been explored yet. This gap in literature is critical and has to be explored. In this study the role of behavioural and psychological factors such as obsessive passion, harmonious passion, intrinsic motivation will be explored. To address this gap in knowledge, a conceptual framework is proposed that integrates the motivational aspects into TAM. This framework will be useful to guide both practice and research to study the retention in MOOC courses.

description: We address the task of advertisement detection in broadcast television content. While typically approached from a video-only or audio-visual perspective, we present an audio-only method. Our approach centres on the detection of short silences which exist at the boundaries between programming and advertising, as well as between the advertisements themselves. To identify advertising regions we first locate all points within the broadcast content with very low signal energy. Next, we use a multiple linear regression model to reject non-boundary silences based on features extracted from the local context immediately surrounding the silence. Finally, we determine the advertising regions based on the long-term grouping of detected boundary silences. When evaluated over a 26 hour annotated database covering national and commercial Portuguese television channels we obtain a Matthews correlation coefficient in excess of 0.87 and outperform a freely available audio-visual approach.

description: Context. Classical chemically peculiar stars exhibit atmospheres that are often structured by the effects of atomic diffusion. As a result of these elemental diffusion and horizontal abundance variations, photospheric temperature varies at a given height in the atmosphere. This may lead to horizontal flows in the photosphere. In addition, the suppression of such flows by magnetic field can alter the elemental transport processes. Aims. Using a simplified model of such a structured atmosphere and 2D MHD simulations of a typical He-rich star, we examine atmospheric flows in these chemically peculiar stars which often are strongly magnetic. Methods. We use Zeus-MP which is a Fortran 90 based publicly available parallel finite element modular code. Results. We find that for non-magnetic stars of spectral type BA, atmospheric flow related to horizontal temperature gradient can reach 1.0 km/s yielding mixing timescale of order of tens of days. For the magnetic counterparts, the flow speeds are an order of magnitude lower allowing for stratification of chemical elements. Conclusions. Magnetic field can influence the dynamics in atmospheres significantly. Strong horizontal magnetic field inhibits flow in the vertical direction, while strong vertical magnetic field can suppress horizontal atmospheric flow preventing elemental mixing.

Problem Formulation and Fairness

description: Formulating data science problems is an uncertain and difficult process. It requires various forms of discretionary work to translate high-level objectives or strategic goals into tractable problems, necessitating, among other things, the identification of appropriate target variables and proxies. While these choices are rarely self-evident, normative assessments of data science projects often take them for granted, even though different translations can raise profoundly different ethical concerns. Whether we consider a data science project fair often has as much to do with the formulation of the problem as any property of the resulting model. Building on six months of ethnographic fieldwork with a corporate data science team---and channeling ideas from sociology and history of science, critical data studies, and early writing on knowledge discovery in databases---we describe the complex set of actors and activities involved in problem formulation. Our research demonstrates that the specification and operationalization of the problem are always negotiated and elastic, and rarely worked out with explicit normative considerations in mind. In so doing, we show that careful accounts of everyday data science work can help us better understand how and why data science problems are posed in certain ways---and why specific formulations prevail in practice, even in the face of what might seem like normatively preferable alternatives. We conclude by discussing the implications of our findings, arguing that effective normative interventions will require attending to the practical work of problem formulation.

description: Predictive models are important tools used in all scientific fields. Machine learning (ML) algorithms and statistical models are widely used for decision-making because of their capability to tackle intricate and unique problems. In domains where data are high-dimensional and contain irrelevant and redundant features, ML algorithms are known to have superior performance over traditional (statistical) learning methods. However, researchers and analysts are often faced with a myriad of techniques to choose from, with no clear consensus on which will perform best for their specific task. Considering resource limitations, exhaustive exploration of all available methods is impractical and often fails to yield significant improvements, making it an unadvised approach.In this study, we propose an efficient methodology for benchmarking feature selection and machine-learning algorithms with a practical evaluation in the context of credit scoring. A survey of credit-scoring literature was conducted to identify prevalent and high-performing methods, and a subset of methods was selected based on computational efficiency, interpretability, and predictive performance. The search led to the methods of chi-square, oblique principal component analysis, and genetic algorithm for feature selection, penalized logistic regression, support vector machines, extreme gradient boosted decision trees, and random forest for classification. We then designed a simulation study to evaluate the performance of the selected methods using relevant metrics. These results guided the selection of the most practical and effective methods, which were subsequently tested in a real-world credit-scoring environment. The simulation results indicate that penalized logistic regression and extreme gradient boosting with genetic algorithm feature selection emerged as the best-performing methods for prediction and dimension reduction. Furthermore, the study examined the impact of data characteristics on prediction performance. This research contributes to the method selection and optimization in credit scoring and highlights avenues for further investigation in related research areas.

description: We present a new technique to constrain the gravitational potential of a galaxy from the observed stellar mass surface density alone under a number of assumptions. It uses the classical Eddington Inversion Method to compute the phase-space distribution function (DF) needed for the stars to reside in a given gravitational potential. In essence, each potential defines a set of density profiles, and it is the expansion of the observed profile in this database that provides the DF. If the required DF becomes negative then the potential is inconsistent with the observed stars and can be discarded. It is particularly well-suited for analyzing low-mass low surface brightness galaxies, where photometric but not spectroscopic data can be obtained. The recently discovered low surface brightness galaxy 'Nube' was used to showcase its application. For the observed Nube's stellar core to be reproduced with non-negative DF, cuspy NFW (Navarro, Frenk, and White) potentials are highly disfavored compared with potentials having cores (Schuster-Plummer or rho-230). The method assumes the stellar system to have spherical symmetry and isotropic velocity distribution, however, we discuss simple extensions that relax the need for isotropy and may help to drop the spherical symmetry assumption.

description: We place regional industry structures at centre stage in currency union analysis, decomposing differences between regional and aggregate cycles into "industry structure" and "industry cycle" effects. The industry structure effect indicates whether a region's industry structure causes its cycle to deviate from the aggregate; the industry cycle effect indicates the importance of region-specific shocks in causing a deviation between cycles. We apply the methodology to Australasia. One region, ACT, has a material industry structure effect arising from its heavy central government concentration. No other region has a material industry structure effect; their cycles differ from the aggregate due to region-specific shocks.

SyDog: A Synthetic Dog Dataset for Improved 2D Pose Estimation
Creators: name: Shooter, Moira
Publisher: name: Zenodo
Year: 2021

description: Estimating the pose of animals facilitates the understanding of animal motion and can permit the early diagnosis of lameness, improve animal performance in sports such as horse racing, permit robots to learn from animal motion data and produce realistic animal 3D animations and representations.
 Human pose estimation deep learning models have been able to achieve high levels of performance due to the huge amount of training data available. Achieving the same results for animal pose estimation is harder due to the lack of animal pose datasets. Traditionally, to solve this problem, thousands of images are manually annotated. However, this is labour intensive and expensive. To address this problem, we introduce SyDog: a synthetic dataset of dogs containing 2-dimensional annotations generated using the game engine, Unity. We demonstrate that pose estimation models trained on SyDog achieve better performance than models trained purely on real data and significantly reduce the need for the labour intensive labelling of images.

description: We compare current 1D and multi-dimensional atmosphere modelling approaches for massive stars to understand their strengths and shortcomings. We calculate averaged stratifications from selected 2D calculations for O stars -- corresponding to the spectral types O8, O4, and O2 -- to approximate them with 1D stellar atmosphere models using the PoWR model atmosphere code and assuming a fixed $β-$law for the wind regime. We then study the effects of our approximations and assumptions on current spectral diagnostics. In particular, we focus on the impact of an additional turbulent pressure in the subsonic layers of the 1D models. To match the 2D averages, the 1D stellar atmosphere models need to account for turbulent pressure in the hydrostatic equation. Moreover, an adjustment of the connection point between the (quasi-)hydrostatic regime and the wind regime is required. The improvement between the density stratification of 1D model and 2D average can be further increased if the mass-loss rate of the 1D model is not identical to those of the 2D simulation, but typically $\sim0.2\,$dex higher. Especially for the early type star, this implies a significantly more extended envelope with a lower effective temperature. Already the inclusion of a constant turbulence term in the solution of the hydrostatic equation sufficiently reproduces the 2D-averaged model density stratifications. The addition of a significant turbulent motion also smoothens the slope of the radiative acceleration term in the (quasi-)hydrostatic domain, with several potential implications on the total mass-loss rate inferred from 1D modelling. Concerning the spectral synthesis, the addition of a turbulence term in the hydrostatic equation mimics the effect of a lower surface gravity, potentially presenting a solution to the ``mass discrepancy problem'' between the evolutionary and spectroscopy mass determinations.

description: Despite a diversity of about 10 000 extant species, the sophisticated avian ‘body plan’ has not much changed once it was achieved around 160 Ma after the origin of powered flight. All birds are bipedal having wings, a rigid trunk, a short and ossified tail, a three-segmented leg and digitigrade feet. The avian neck, however, has always been regarded as a classic example of high variability ranging from short necks in songbirds to extremely long, serpentine necks in herons. Yet, the wide array of small to very large species makes it difficult to evaluate the actual neck length. Here, we investigate the evolution of the vertebral formulae in the neck of birds and the scaling relationships between skeletal dimensions and body size. Cervical count in birds is strongly related to phylogeny, with only some specialists having an exceptional number of vertebrae in the neck. In contrast with mammals, the length of the cervical vertebral column increases as body size increases and, thus, body size does not constrain neck length in birds. Indeed, neck length scales isometrically with total leg length suggesting a correlated evolution between both modules. The strong integration between the cervical and pelvic module in birds is in contrast with the decoupling of the fore- and hindlimb module and may be the result of the loss of a functionally versatile forelimb due to the evolution of powered flight.

description: We describe methods of estimating the entire Lyapunov spectrum of a spatially extended system from multivariate time-series observations. Provided that the coupling in the system is short range, the Jacobian has a banded structure and can be estimated using spatially localised reconstructions in low embedding dimensions. This circumvents the ``curse of dimensionality'' that prevents the accurate reconstruction of high-dimensional dynamics from observed time series. The technique is illustrated using coupled map lattices as prototype models for spatio-temporal chaos and is found to work even when the coupling is not strictly local but only exponentially decaying.

description: Context: This paper focuses on a class of galaxies characterised by an extremely low surface brightness: the ultra-diffuse galaxies (UDGs). We used new integral-field spectroscopic data from the ESO Large Programme Looking into the faintEst WIth MUSE (LEWIS) project. Aims: Our main goals are addressing the formation channels and investigating possible correlations of their observational properties. In particular, we derive their stellar kinematics and dynamical properties. Methods: We extract the 1D stacked spectrum inside the effective radius to obtain an unbiased measure of $σ_{\rm eff}$. To derive the spatially-resolved stellar kinematics, we first apply the Voronoi tessellation algorithm to bin the spaxels in the datacube and then follow the same prescription adopted for the 1D case. In addition, we extract the velocity profiles along the galaxy's major and minor axes. Results: We find that 7 out of 18 UDGs in LEWIS show a mild rotation, 5 do not have evidence of any rotation, and the remaining 6 UDGs are unconstrained cases. This is the first large census of velocity profiles for UDGs. On average, UDGs in LEWIS are characterised by low values of $σ_{\rm eff}$, comparable with available values from the literature. In the Faber-Jackson relation plane, we found a group of UDGs consistent with the relation within the errorbars, whereas outliers are objects with non-negligible rotation components. UDGs and LSBs in LEWIS have larger dark matter content than dwarf galaxies with similar total luminosity. We do not find clear correlations between the derived properties and the local environment. Conclusions: Based on the stellar kinematics, two classes of UDGs are found in the Hydra I cluster: the rotating and non-rotating systems. This result, combined with other structural properties, can help to discriminate between the several formation scenarios proposed for UDGs.

Improvisation in Early Jazz; A Kid Ory performance study
Creators: name: Ingham, James
Publisher: name: Zenodo
Year: 2021

description: During the 1920s Kid Ory recorded an extraordinary body of work with some of the greatest names in jazz of the time, most famously with Louis Armstrong on the Hot Five recordings. This presentation will review key melodic, harmonic, and rhythmic features of Orys solos, as well as the idiosyncrasies of Orys performance style, whilst placing the recordings in the context in which they were made. Transcriptions of key improvisations support analysis of melody and harmony, to clearly identify what Kid Ory played. Alongside this, time and swing analysis examines the performances themselves, to help us further understand the idiosyncrasies of his style and approach to improvisation. Comparisons of different recordings of the famous jazz standard Savoy Blues, which Ory recorded many times in his career with different ensembles, will be analysed to further support or challenge the trends exposed in his improvisatory work, particularly regarding the nature of spontaneity and authenticity. The aims of the findings are to challenge current perceptions of Kid Orys contribution to the development of jazz, but more importantly reassess our analytical approach to understanding how musicians improvise.

description: Common signal-processing approximations produce artefacts when timing pulsars in relativistic binary systems, especially edge-on systems with tight orbits, such as the Double Pulsar. In this paper, we use extensive simulations to explore various patterns that arise from the inaccuracies of approximations made when correcting dispersion and Shapiro delay. In a relativistic binary, the velocity of the pulsar projected onto the line-of-sight varies significantly on short time scales, causing rapid changes in the apparent pulsar spin frequency, which is used to convert dispersive delays to pulsar rotational phase shifts. A well-known example of the consequences of this effect is the artificial variation of dispersion measure (DM) with binary phase, first observed in the Double Pulsar 20 years ago. We show that ignoring the Doppler shift of the spin frequency when computing the dispersive phase shift exactly reproduces the shape and magnitude of the reported DM variations. We also simulate and study two additional effects of much smaller magnitude, which are caused by the assumption that the spin frequency used to correct dispersion is constant over the duration of the sub-integration and over the observed bandwidth. We show that failure to account for these two effects leads to orbital phase-dependent dispersive smearing that leads to apparent orbital DM variations. The functional form of the variation depends on the orbital eccentricity. In addition, we find that a polynomial approximation of the timing model is unable to accurately describe the Shapiro delay of edge-on systems with orbits less than 4 hours, which poses problems for the measurements of timing parameters, most notably the Shapiro delay. This will be a potential issue for sensitive facilities like the FAST and the forthcoming Square Kilometre Array (SKA); therefore, a more accurate phase predictor is indispensable.

title: Mob Family Proteins and Tricornered Kinase Are Required to Form Dorsal Appendages of the Drosophila Eggshell

description: To understand how complex tissues are formed, we need to understand how cells communicate with other cells to build structures. In Drosophila melanogaster, epithelial cells form tubular structures to shape the dorsal appendages on the eggshells. One signaling pathway needed for this event is the Hippo-like kinase intracellular pathway. I focus on two key components in this pathway: the NDR kinase Tricornered (Trc) and Mob proteins. In eukaryotes, Mob proteins are known to interact with NDR kinases to promote their activation. The Hippo- like pathway involves the NDR kinase Trc; however, the specific Mob protein(s) that interact with Trc are unclear. I studied the functions of Trc, Mob1, Mob2, and Mob4 in several aspects of tube formation using RNA interference (RNAi) in all somatic follicle cells of the ovary in vivo. First, I evaluated the dorsal appendages on the eggshells that were formed by females with reduced levels of Trc, Mob1, or Mob2 and found that these structures were shortened or lengthened compared to controls, and also widened at the base. These phenotypes led me to investigate how the organization of the follicle cell tubes for dorsal appendage formation were affected by RNAi of these gene products. Two types of follicle cells create the dorsal appendages, called roof and floor cells. To visualize the cell organization, I used immunofluorescence and confocal microscopy. I then evaluated the organization of each cell type at the specific stages of oogenesis when the tube structures are formed. I found that floor cell organization was most frequently abnormal. Roof cell organization appeared to be affected rarely. I then evaluated whether components of the STRIPAK complex (an established antagonist of the Hippo pathway) contributed to dorsal appendage formation, using RNAi against core STRIPAK components; Strip, Striatin, and Mob4. I then examined the dorsal appendages laid by the females with reduced levels of these gene products. RNAi against each component led to similar abnormalities in the dorsal appendages. These results indicated that STRIPAK also plays a role in proper dorsal appendage formation. This work reveals key components in the morphogenesis of dorsal appendages.
