description: When fitting cosmological models to data, a Bayesian framework is commonly used, requiring assumptions on the form of the likelihood and model prior. In light of current tensions between different data, it is interesting to investigate the robustness of cosmological measurements to statistical assumptions about the likelihood distribution from which the data was drawn. We consider the impact of changes to the likelihood caused by uncertainties due to the finite number of mock catalogs used to estimate the covariance matrix, leading to the replacement of the standard Gaussian likelihood with a multivariate $t$-distribution. These changes to the likelihood have a negligible impact on recent cosmic microwave background (CMB) lensing and baryon acoustic oscillation (BAO) measurements. We then extend our analysis to perform a sensitivity test on the Gaussian likelihoods typically adopted, considering how increasing the size of the tails of the likelihood (again using a $t$-distribution) affects cosmological inferences. For an open $Λ$CDM model constrained by BAO alone, we find that increasing the weight in the tails shifts and broadens the resulting posterior on the parameters, with a $\sim$0.2-0.4$σ$ effect on $Ω_Λ$ and $Ω_{\rm k}$. In contrast, the CMB temperature and polarization constraints in $Λ$CDM showed less than 0.03$σ$ changes in the parameters, except for $\{τ$, ln($10^{10}A_{\rm s})$, $σ_8$, $S_8$, $σ_8Ω_{\rm m}^{0.25}$, $z_{\rm re}$, $10^9A_{\rm s}e^{-2τ}\}$ which shifted by around 0.1-0.2$σ$. If we use solely $\ell < 30$ data, the amplitude $A_{\rm s} e^{-2τ}$ varies in the posterior mean by 0.7$σ$ and the error bars increase by 6%. We conclude, at least for current-generation CMB and BAO measurements, that uncertainties in the shape and tails of the likelihood do not contribute to current tensions.

description: The study of gas-phase metallicity and its spatial distribution at high redshift is crucial to understand the processes that shaped the growth and evolution of galaxies in the early Universe. Here we study the spatially resolved metallicity in three systems at $z\sim6-8$, namely A2744-YD4, BDF-3299, and COSMOS24108, with JWST NIRSpec IFU low-resolution ($R\sim100$) spectroscopic observations. These are among the highest-$z$ sources in which metallicity gradients have been probed so far. Each of these systems hosts several spatial components in the process of merging within a few kpc, identified from the rest-frame UV and optical stellar continuum and ionised gas emission line maps. The sources have heterogeneous properties, with stellar masses log($M_*/M_\odot) \sim 7.6-9.3$, star formation rates (SFRs) $\sim1-15$ $M_\odot$ yr$^{-1}$, and gas-phase metallicities 12+log(O/H) $\sim 7.7-8.3$, which exhibit a large scatter within each system. Their properties are generally consistent with those of the highest-$z$ samples to date ($z\sim3-10$), though the sources in A2744-YD4 and COSMOS24108 are at the high end of the mass-metallicity relation (MZR) defined by the $z\sim3-10$ sources. Moreover, the targets in this work follow the predicted slope of the MZR at $z\sim 6-8$ from most cosmological simulations. The gas-phase metallicity gradients are consistent with being flat in the main sources of each system. Flat metallicity gradients are thought to arise from gas mixing processes on galaxy scales, such as mergers or galactic outflows and SN winds driven by intense stellar feedback, which wash out any gradient formed in the galaxy. The existence of flat gradients at $z\sim6-8$ sets also important constraints on cosmological simulations and chemical evolution models, whose predictions on the cosmic evolution of metallicity gradients differ significantly, but are mostly limited to $z<3$ so far.

description: Raman spectroscopy is widely used across scientific domains to characterize the chemical composition of samples in a non-destructive, label-free manner. Many applications entail the unmixing of signals from mixtures of molecular species to identify the individual components present and their proportions, yet conventional methods for chemometrics often struggle with complex mixture scenarios encountered in practice. Here, we develop hyperspectral unmixing algorithms based on autoencoder neural networks, and we systematically validate them using both synthetic and experimental benchmark datasets created in-house. Our results demonstrate that unmixing autoencoders provide improved accuracy, robustness and efficiency compared to standard unmixing methods. We also showcase the applicability of autoencoders to complex biological settings by showing improved biochemical characterization of volumetric Raman imaging data from a monocytic cell.

description: Discovering pragmatic and efficient approaches to construct $\varepsilon$-approximations of quantum operators such as real (imaginary) time-evolution propagators in terms of the basic quantum operations (gates) is challenging. Prior $\varepsilon$-approximations are invaluable, in that they enable the compilation of classical and quantum algorithm modeling of, e.g., dynamical and thermodynamic quantum properties. In parallel, symmetries are powerful tools concisely describing the fundamental laws of nature; the symmetric underpinnings of physical laws have consistently provided profound insights and substantially increased predictive power. In this work, we consider the interplay between the $\varepsilon$-approximate processes and the exact symmetries in a semicoherent context -- where measurements occur at each logical clock cycle. We draw inspiration from Pascual Jordan's groundbreaking formulation of nonassociative, but commutative, symmetric algebraic form. Our symmetrized formalism is then applied in various domains such as quantum random walks, real-time evolutions, variational algorithm ansatzes, and efficient entanglement verification. Our work paves the way for a deeper understanding and greater appreciation of how symmetries can be used to control quantum dynamics in settings where coherence is a limited resource.

description: In this paper, we compute departures in the black hole thermodynamics induced by either geometric or topological corrections to general relativity. Specifically, we analyze the spherically symmetric spacetime solutions of two modified gravity scenarios with Lagrangians $\mathcal{L}\sim R^{1+ε}$ and $\mathcal{L}\sim R+ε\, \mathcal{G}^2$, where $\mathcal{G}$ is the Euler density in four dimensions, while $ 0<ε\ll 1$ measures the perturbation around the Hilbert-Einstein action. Accordingly, we find the expressions of the Bekenstein-Hawking entropy by the Wald formula, and the black hole temperature and horizon of the obtained solutions. We then investigate the heat capacities in terms of the free parameters of the theories under study. In doing so, we show that healing the problem of negative heat capacities can be possible under particular choices of the free constants, albeit with limitations on the masses allowed for the black hole solutions.

description: The quantum efficiency of AlGaN ultraviolet light-emitting diodes (LEDs) declines (droops) at increasing operating powers due to Auger-Meitner recombination (AMR). Using first-principles density-functional theory, we show that indirect AMR mediated by electron-phonon coupling and alloy disorder can induce bulk $C$ coefficients as large as $\sim10^{-31}$ cm$^6$/s. Furthermore, we find that the confinement of carriers by polarization fields within quantum wells severely relaxes crystal-momentum conservation, which exacerbates the rate of AMR over radiative recombination by an order of magnitude relative to the bulk. This results in a striking decrease in quantum efficiency at high power. Suppressing polarization fields and jointly increasing the well width would greatly mitigate AMR and efficiency droop.

Fifteenth Century Changes, and Sixteenth Century Evidence for Bell Founding in Easton Parish Church, Cambridgeshire

description: In 2010, while the ground floor of the tower of St Peter's church, Easton, was being excavated for a new floor, evidence for a temporary bell foundry was discovered. Excavation below an exposed circular scorch mark revealed a shallow pit edged with tiles. Near the pit the remains of a small furnace or oven, also scorched from intense heat, were uncovered, and close by those was a quantity of refined clay on a slate, apparently ready for use. The use of a shallow, heated pit for drying out bell moulds is supported by descriptions of bell founding from the 12th century onwards. The scorch mark and pit in the tower had a diameter sufficient to accommodate one of the two surviving 16th century bells, one of which is thought to predate the Reformation. The two bells have been attributed to the Newcombe family from Leicestershire. The late 14th century tower and early 15th century rood screen suggest a period of wealth affording the alteration and changes to the building that included the recasting and re-hanging of the bells in a 'new' 16th century bell frame.

description: The postselection technique is an important proof technique for proving the security of quantum key distribution protocols against coherent attacks. In this work, we go through multiple steps to rigorously apply the postselection technique to optical quantum key distribution protocols. First, we place the postselection technique on a rigorous mathematical foundation by fixing a technical flaw in the original postselection paper. Second, we extend the applicability of the postselection technique to prepare-and-measure protocols by using a de Finetti reduction with a fixed marginal. Third, we show how the postselection technique can be used for decoy-state protocols by tagging the source. Finally, we extend the applicability of the postselection technique to realistic optical setups by developing a new variant of the flag-state squasher. We also improve existing de Finetti reductions, which reduce the effect of using the postselection technique on the key rate. These improvements can be more generally applied to other quantum information processing tasks. As an example to demonstrate the applicability of our work, we apply our results to the time-bin encoded three-state protocol. We observe that the postselection technique performs better than all other known proof techniques against coherent attacks.

description: Superconductivity and magnetism are competing effects that can coexist in certain regimes. Their co-existence leads to unexpected new behaviors that include the onset of exotic electron pair mechanisms and topological phases. In this work, we study the properties of a Josephson junction between two spin-split superconductors. The spin-splitting in the superconductors can arise from either the coupling to a ferromagnetic material or an external magnetic field. The properties of the junction are dominated by the Andreev bound states that are also split. One of these states can cross the superconductor's Fermi level, leading to a ground state transition characterized by a suppressed supercurrent. We interpret the supercurrent blockade as coming from a dominance of p-wave pairing close to the junction, where electrons at both sides of the junction pair. To support this interpretation, we analyze the different pairing channels and show that p-wave pairing is favored in the case where the magnetization of the two superconductors is parallel and suppressed in the anti-parallel case. We also analyze the noise spectrum that shows signatures of the ground state transition in the form of an elevated zero-frequency noise.

description: Outflows from galaxies, driven by active galactic nuclei and star formation activity, spread magnetic fields into the intergalactic medium. Importance of this process can be assessed using cosmological magneto-hydrodynamic numerical modelling of the baryonic feedback on the Large Scale Structure, like that of Illustris-TNG simulations. We use the Faraday Rotation Measure data of LOFAR Two-Meter Sky Survey (LOTSS) to test the Illustris-TNG baryonic feedback model. We show that the Illustris-TNG over-predicts the root-mean-square of the residual Rotation Measure in LOTSS. This suggests that the "pollution" of the intergalactic medium by the magnetized outflows from galaxies is less important than the estimate from the Illustris-TNG. This fact provides a support to the hypothesis that the volume-filling large scale magnetic fields found in the voids of the Large Scale Structure are likely of cosmological origin.

description: Aquaponic systems have potential to improve water and nutrient use efficiency compared to separately operated recirculating aquaculture systems (RAS) and hydroponic facilities. However, fish feeds are optimized for fish performance and low effluent nutrient discharge instead of integrated production of fish and plants, often leading to deficiencies of certain dissolved plant nutrients in RAS water. This study tested the effect of gradually replacing a blend of animal by-products (poultry by-product meal, catfish by-product meal, poultry blood meal) in a marine ingredient-free and entirely animal protein-based diet with a blend of common plant protein sources in four quasi-realistic isonitrogenous (42% crude protein) and isocaloric (20 MJ/kg) diets for African catfish on growth performance, body composition and nutrient release in dissolved and solid form into RAS water. Reducing the contribution of animal proteins to dietary protein from 100% over 75% and 50% to 25% resulted in the best biomass gain (%), feed conversion ratio (dry matter basis) and protein efficiency ratio for the 50% level, with differences, however, non-significant compared to the 100% and 75% level. At the 25% level, i.e. the highest level of plant protein inclusion, significant impairments regarding these growth indices as well as body ash, P and Ca were recorded compared to all other diets. No differences were observed for total dissolved 4 release per unit of feed between diets. Higher animal protein contribution lead to significantly higher release of dissolved P and Ca into RAS water, whereas increasing plant protein contribution caused significantly higher release of dissolved K, Mg and B. A mass balance of dietary nutrient fate revealed that N, P, K, S and Mg primarily ended up in fish biomass and in dissolved form in RAS water rather than in collected solids, while Ca, Fe, Mn, Zn and Cu predominantly ended up in solids and fish biomass rather than in dissolved form in RAS water. Modeling daily RAS water exchange rates needed to achieve the dissolved N concentration of a standard hydroponic nutrient solution on the basis of dissolved N release per unit of feed revealed that the entirely animal protein-based diet could reach 100%, 86% and 5% of the required dissolved N, P and K concentrations and that the diet with the highest plant protein inclusion could reach 100%, 14% and 15%, both at an exchange rate of 118 L/kg of feed/day.

description: The synthesis of composites comprising chitosan (CS) and magnetite using the co-precipitation method yielded a compound denoted as CS/Fe3O4, which demonstrated magnetic properties. FTIR analysis confirmed the presence of magnetite nanoparticles within the composite. This CS/Fe3O4 composite proved to be highly efficient in adsorbing tetracycline (TC) from solutions of tetracycline hydrochloride (HTCCl), achieving an adsorption efficiency exceeding 65%. Moreover, the composite maintained its adsorption capacity over five cycles of sorption-desorption, indicating its robustness and reusability. The Langmuir isotherm provided a suitable description of the liquid-solid equilibrium of TC at 25 °C and 35 °C. Thermodynamic analysis revealed interesting insights into the nature of TC adsorption on CS. At low concentrations, the adsorption process was found to be exothermic, while at very high concentrations, it became endothermic. This observation suggests that the adsorption of TC at low concentrations is governed by protonation of chitosan and, at high concentrations, by entropic factors, highlighting the importance of considering thermodynamic parameters in understanding the adsorption mechanism. Overall, these findings contribute to the development of efficient and cost-effective adsorbents for the removal of TC from aqueous solutions.

description: Persistent homology naturally addresses the multi-scale topological characteristics of the large-scale structure as a distribution of clusters, loops, and voids. We apply this tool to the dark matter halo catalogs from the Quijote simulations, and build a summary statistic for comparison with the joint power spectrum and bispectrum statistic regarding their information content on cosmological parameters and primordial non-Gaussianity. Through a Fisher analysis, we find that constraints from persistent homology are tighter for 8 out of the 10 parameters by margins of 13-50%. The complementarity of the two statistics breaks parameter degeneracies, allowing for a further gain in constraining power when combined. We run a series of consistency checks to consolidate our results, and conclude that our findings motivate incorporating persistent homology into inference pipelines for cosmological survey data.

description: We investigate the resonance fluorescence features of a small ensemble of closely packed and moderately laser pumped two-level emitters at resonance. The mean distance between any two-level radiators is smaller than the corresponding emission wavelength, such that the dipole-dipole interactions are not negligible. We have found that under the secular approximation, the collective resonance fluorescence spectrum consists of 2N+1 spectral lines, where N is the number of emitters from the sample. The 2N spectral sidebands, symmetrically located around the generalized Rabi frequency with respect to the central line at the laser frequency, are distinguishable if the dipole-dipole coupling strength is larger than the collective spontaneous decay rate. This way, one can estimate the radiators number within the ensemble via measuring of the spontaneously scattered collective resonance fluorescence spectrum. Contrary, if the dipole-dipole coupling is of the order of or smaller than the cooperative spontaneous decay rate, but still non-negligible, the spectrum turns into a Mollow-like fluorescence spectrum, where the two sidebands spectral lines broadens, proportional to the dipole-dipole coupling strength, respectively.

description: Dynamic structural equation models (DSEM) are designed for time series analysis of latent structures. Inherent to the application of DSEM is model parameter estimation, which has to be addressed in many applications by a single time series. In this context, however, the methods currently available either lack estimation quality or are computationally inefficient. Given the era of big data, the necessity for a trade-off between these properties may be detrimental to the applicability of DSEM. The paper is aimed at tackling this trade-off by proposing a novel estimator recursioning technique (ER technique) that facilitates the development of computationally efficient raw-data maximum likelihood estimation algorithms through data transformation, covariance matrix block decomposition, likelihood function reduction, and estimator recursioning steps. The ER technique is introduced by applying it to a special case of the general dynamic structural equation model that encompasses a noisy Wiener-process-type structure with input from the factor-analytic model. The resulting algorithm has been verified through a number of numerical experiments as well as implemented in a brand new R package EMLI, which is available on CRAN.

description: We present a method for Bayesian structural equation modeling of sample correlation matrices as correlation structures. The method transforms the sample correlation matrix to an unbounded vector using the matrix logarithm function. Bayesian inference about the unbounded vector is performed assuming a multivariate-normal likelihood, with a mean based on the transformed model-implied correlation matrix, and a covariance assumed to be of known form. Using Monte Carlo simulation, we examine the performance of the method with normal and ordinal indicators, as well as the capacity of the method to estimate models that account for misspecification. The performance of the approach is often adequate suggesting that the proposed method can be used for Bayesian analysis of correlation structures. We conclude with a discussion of potential applications of the approach, as well as future directions needed to further develop the method.

description: The spectral amplitude of the merger-ringdown gravitational wave (GW) emitted by a comparable mass-ratio black hole merger is modeled by the greybody factor of the remnant black hole. We also include the post-Newtonian correction to the greybody factor model. Our model includes only a few fitting parameters, which could evade the overfitting issue. We perform the mass-spin inference from the SXS data without tuning the data range of each SXS waveform. Also, we find that the exponential damping in the ringdown spectral amplitude can be modeled well with the exponential damping in the greybody factor at high frequencies. Our findings could be consistent with a conjecture that the light ring of the remnant black hole, which sources the ringdown, forms as early as during the merger stage. We discuss the formation of the light ring in the static binary solution as a first step towards the understanding of how the separation of merging black holes may affect the formation of the light ring.

Este artículo tiene varios aspectos: a) el fondo, que es el conflicto, b) el intento por resolverlo: la conciliación y las razones de su fracaso, c) lo positivo que aportó la conciliación, d) las medidas de contención y e) cual es el papel de personas acompañantes ajenas a las comunidades en procesos comunitarios y unas reflexiones finales.

description: Understanding the behavior of the matter power spectrum on non-linear scales beyond the $Λ$CDM model is crucial for accurately predicting the large-scale structure (LSS) of the Universe in non-standard cosmologies. In this work, we present an analysis of the non-linear matter power spectrum within the framework of interacting dark energy-dark matter cosmologies (IDE). We employ N-body simulations and theoretical models to investigate the impact of IDE on these non-linear scales. Beginning with N-body simulations characterized by a fixed parameter space delineated by prior observational research, we adeptly fit the simulated spectra with a simple parametric function, achieving accuracy within 5\%. Subsequently, we refine a modified halo model tailored to the IDE cosmology, exhibiting exceptional precision in fitting the simulations down to scales of approximately 1 h/Mpc. To assess the model's robustness, we conduct a forecast analysis for the Euclid survey, employing our refined model. We find that the coupling parameter $ξ$ will be constrained to $σ(ξ) = 0.0110$. This marks a significant improvement by an order of magnitude compared to any other current observational tests documented in the literature. These primary findings pave the way for a novel preliminary approach, enabling the utilization of IDE models for observational constraints concerning LSS data on non-linear scales.

description: Anomaly detection is an active research field that widely applies to commercial applications to detect unusual patterns or outliers. Time series anomaly detection provides valuable insights into mission and safety-critical applications using ever-growing temporal data, including continuous streaming time series data from the Internet of Things (IoT), sensor networks, healthcare, stock prices, computer metrics, and application monitoring. While Generative Adversarial Networks (GANs) demonstrate promising results in time series anomaly detection, the opaque nature of generative deep learning models lacks explainability and hinders broader adoption. Understanding the rationale behind model predictions and providing human-interpretable explanations are vital for increasing confidence and trust in machine learning (ML) frameworks such as GANs. This study conducted a structured and comprehensive assessment of post-hoc local explainability in GAN-based time series anomaly detection using SHapley Additive exPlanations (SHAP). Using publicly available benchmarking datasets approved by Purdue’s Institutional Review Board (IRB), this study evaluated state-of-the-art GAN frameworks identifying their advantages and limitations for time series anomaly detection. This study demonstrated a systematic approach in quantifying the extent of GAN-based time series anomaly explainability, providing insights for businesses when considering adopting generative deep learning models. The presented results show that GANs capture complex time series temporal distribution and are applicable for anomaly detection. The analysis from this study shows SHAP can identify the significance of contributing features within time series data and derive post-hoc explanations to quantify GAN-detected time series anomalies.
