Year: 2022

description: The challenges facing European regions undergoing structural transformations as they transition towards sustainable development pathways have attracted increasing interest in recent years. Straddling the border between Germany and Poland, Lusatia is experiencing considerable transformation pressure. Various domestic and European funding programmes, for example under the umbrella of the European Green Deal, are intended to cushion the impacts of the phase-out or reduction of coal-fired power generation. The recently adopted EU Just Transition Mechanism aims to support sustainable structural transformations and the broader goal of achieving climate neutrality by mitigating impacts on the workforce and contributing to the diversification of economies in the most affected areas. Funds made available through this mechanism should be deployed in consultation with regional stakeholders in Lusatia to complement national support measures. Further funding programmes are available targeting various policy areas and could be harnessed to strengthen integration throughout the region. Funding programmes that are centrally managed by the European Commission (i.e. not under shared management with national governments) are of particular interest in this context. Closer political and economic cooperation, coupled with a deeper exchange of experience, can accelerate regional integration and guide processes of structural transformation towards sustainable outcomes. However, there are some practical hurdles to overcome in border regions. The primary objectives in using available EU funding are to mitigate the social impacts of processes of structural transformation and to deliver a just transition at all levels. Measures funded through these programmes should be aligned with the sustainable development goals (SDGs) and contribute to the goal of achieving climate neutrality.

description: We consider a two-stage estimation method for linear regression. First, it uses the lasso in Tibshirani to screen variables and, second, re-estimates the coefficients using the least-squares boosting method in Friedman on every set of selected variables. Based on the large-scale simulation experiment in Hastie, Tibshirani, and Tibshirani, lassoed boosting performs as well as the relaxed lasso in Meinshausen and, under certain scenarios, can yield a sparser model. Applied to predicting equity returns, lassoed boosting gives the smallest mean-squared prediction error compared to several other methods.

description: It has been proposed that complex populations, such as those that arise in genomics studies, may exhibit dependencies among observations as well as among variables. This gives rise to the challenging problem of analyzing unreplicated high-dimensional data with unknown mean and dependence structures. Matrix-variate approaches that impose various forms of (inverse) covariance sparsity allow flexible dependence structures to be estimated, but cannot directly be applied when the mean and covariance matrices are estimated jointly. We present a practical method utilizing generalized least squares and penalized (inverse) covariance estimation to address this challenge. We establish consistency and obtain rates of convergence for estimating the mean parameters and covariance matrices. The advantages of our approaches are: (i) dependence graphs and covariance structures can be estimated in the presence of unknown mean structure, (ii) the mean structure becomes more efficiently estimated when accounting for the dependence structure among observations; and (iii) inferences about the mean parameters become correctly calibrated. We use simulation studies and analysis of genomic data from a twin study of ulcerative colitis to illustrate the statistical convergence and the performance of our methods in practical settings. Several lines of evidence show that the test statistics for differential gene expression produced by our methods are correctly calibrated and improve power over conventional methods.

description: Type Ia Supernovae (SNe Ia) may originate from a wide variety of explosion scenarios and progenitor channels. They exhibit a factor of about 10 difference in brightness and, thus, a differentiation in the mass of 56Ni->56Co->56 Fe. We present a study on the fate of positrons within SNe Ia in order to evaluate their escape fractions and energy spectra. Our detailed Monte Carlo transport simulations for positrons and gamma-rays include both beta + decay of 56 Co and pair production. We simulate a wide variety of explosion scenarios, including the explosion of white dwarfs (WD) close to the Chandrasekhar mass, M(Ch), He-triggered explosions of sub-M Ch WDs, and dynamical mergers of two WDs. For each model, we study the influence of the size and morphology of the progenitor magnetic field between 1 and 1E13 G. Population synthesis based on the observed brightness distribution of SNe Ia was used to estimate the overall contributions to Galactic positrons due to escape from SN Ia. We find that this is dominated by normal-bright SNe Ia, where variations in the distribution of emitted positrons are small. We estimate a total SNe Ia contribution to the Galactic positrons of < 2% and, depending on the magnetic field morphology, less than 6...20% for M(Ch) and sub-M(Ch), respectively.

description: The purpose of this paper is to analyze the place of occupational health and safety management system (OHSMS) within the integrated management system. Implementation aspects of management systems are discussed, namely the different management system standards used for registration, for example ISO 14001, ISO 9001, OHSAS 18001, ISO 27001, the order in which they were implemented, the time required for each implementation, as well as the scope of integration of these management system standards into a single Integrated Management System and the level of integration. In order to do so, some of the results of a survey carried out in 81 organizations registered to at least two management systems selected from popular international standards, e.g.: ISO 9001, ISO 14001, OHSAS 18001, ISO/IEC 27001, ISO 22000 were used. OHSMS is not the system that is implemented as a first one. Usually it is implemented after or simultaneously with ISO 9001 and ISO 14001 standards. Time of implementation of MSSs in second and further round of implementation is shorter than during the implementation of first standards. There is a higher level of integration of implemented management standards in organizations where one of the standards in OHSMS, than in a companies without OHSMS. The paper analyses those sequences of management systems implementation of safety management systems with other system, that allow organizations to achieve higher levels of integration and presents a possible pattern for the companies initiating the integration process.

description: This article considers the estimation of quantile treatment effects under the assumption of unconfoundedness given quasi-experimental data. We propose a semiparametric single-index method to estimate the propensity score. Our approach overcomes the curse of dimensionality issue of a nonparametric propensity score and can handle a moderately large dimension of covariates. It is more flexible than the parametric propensity score and thereby alleviates the possible model misspecification problem. We derive the asymptotic distribution of the quantile treatment effect estimator that is based on the semiparametric propensity score. We also propose a consistent variance estimator and construct the confidence intervals for the QTE estimator. Monte Carlo simulation results show that the proposed estimator performs well in finite samples and the confidence intervals have adequate coverage rates. We demonstrate the usefulness of our method by applying it to a study of the quantile treatment effects of college education on income.

The X-ray activity of the young solar-like star Kepler-63 and the structure of its corona

description: The X-ray satellite XMM-Newton has so far revealed coronal cycles in seven solar-like stars. In this sample, the youngest stars $ε$ Eridani (400 Myr) and $ι$ Horologii (600 Myr) display the shortest X-ray cycles and the smallest cycle amplitudes. The corona of $ε$ Eridani was modelled in terms of solar magnetic structures (active regions, cores of active regions and flares) at varying filling factors. The study revealed that 65-95% of its corona is covered with magnetic structures, and this was held responsible for the low X-ray cycle amplitude. It was also hypothesized that the basal surface coverage with magnetic structures may be higher on the corona of younger solar-like stars. To investigate this hypothesis, we study the solar-like star Kepler-63 in the X-rays. With an age of 210 Myr and a photospheric cycle of 1.27 yr, it is so far the youngest star observed in X-rays with the aim of revealing a coronal cycle. In the long-term X-ray lightcurve we do not reveal a periodic variation of the X-ray luminosity, but a factor two change would be possible. As for the case of $ε$ Eridani, we modelled the corona of Kepler-63 with magnetic structures observed on the Sun. The study suggests that 100% of the corona is composed of cores and flares of Class M, justifying the absence of an X-ray cycle and confirming the analogous results derived for $ε$ Eridani. Finally, we establish an empirical relation between the cycle amplitude and the X-ray surface flux . From the absence of a coronal cycle in Kepler-63 we infer that stars with higher X-ray flux than Kepler-63 must host a significant fraction of higher-energetic flares than those necessary to model the corona of Kepler-63. Our study opens new ground for studies of the solar-stellar analogy and the joint exploration of resolved and unresolved variability in stellar X-ray lightcurves.

description: The number of studies where the primary measurement is a matrix is exploding. In response to this, we propose a statistical framework for modeling populations of repeatedly observed matrix-variate measurements. The 2D structure is handled via a matrix-variate distribution with decomposable row/column-specific covariance matrices and a linear mixed effect framework is used to model the multilevel design. The proposed framework flexibly expands to accommodate many common crossed and nested designs and introduces two important concepts: the between-subject distance and intra-class correlation coefficient, both defined for matrix-variate data. The computational feasibility and performance of the approach is shown in extensive simulation studies. The method is motivated by and applied to a study that monitored physical activity of individuals diagnosed with congestive heart failure (CHF) over a 4- to 9-month period. The long-term patterns of physical activity are studied and compared in two CHF sub-subgroups: with and without adverse clinical events.

description: We consider the problem of constrained motion along a conic path under a given external potential function. The model is described as a second-class system capturing the behavior of a certain class of specific quantum field theories. By exhibiting a suitable integration factor, we obtain the general solution for the associated non-linear differential equations. We perform the canonical quantization in a consistent way in terms of the corresponding Dirac brackets. We apply the Dirac-Bergmann algorithm to unravel and classify the whole internal constraints structure inherent to its dynamical Hamiltonian description, obtain the proper extended Hamiltonian function, determine the Lagrange multiplier and compute all relevant Poisson brackets among the constraints, Hamiltonian and Lagrange multiplier. The complete Dirac brackets algebra in phase space as well as its physical realization in terms of differential operators is explicitly obtained.

description: The Brans-Dicke (BD) theory is the simplest Scalar-Tensor theory of gravity, which can be considered as a candidate of modified Einstein's theory of general relativity. In this work, we forecast the constraints on BD theory in the CSST galaxy clustering spectroscopic survey with a magnitude limit $\sim 23$ AB mag for point-source 5$σ$ detection. We generate mock data based on the zCOSMOS catalog and consider the observational and instrumental effects of the CSST spectroscopic survey. We predicate galaxy power spectra in the BD theory from $z=0$ to 1.5, and the galaxy bias and other systematical parameters are also included. The Markov Chain Monte Carlo (MCMC) technique is employed to find the best-fits and probability distributions of the cosmological and systematical parameters. A Brans-Dicke parameter $ζ$ is introduced, which satisfies $ζ=\ln \left(1+\frac{1}ω\right)$. We find that the CSST spectroscopic galaxy clustering survey can give $|ζ|<10^{-2}$, or equivalently $|ω|>\mathcal{O}(10^2)$ and $|\dot{G}/G|<10^{-13}$, under the assumption $ζ= 0$. These constraints are almost at the same order of magnitude compared to the joint constraints using the current cosmic microwave background (CMB), baryon acoustic oscillations (BAO), and Type Ia supernova (SN Ia) data, indicating that the CSST galaxy clustering spectroscopic survey would be powerful to constrain the BD theory and other modified gravity theories.

description: Vector autoregressive (VAR) models aim to capture linear temporal interdependencies among multiple time series. They have been widely used in macroeconomics and financial econometrics and more recently have found novel applications in functional genomics and neuroscience. These applications have also accentuated the need to investigate the behavior of the VAR model in a high-dimensional regime, which provides novel insights into the role of temporal dependence for regularized estimates of the model’s parameters. However, hardly anything is known regarding properties of the posterior distribution for Bayesian VAR models in such regimes. In this work, we consider a VAR model with two prior choices for the autoregressive coefficient matrix: a nonhierarchical matrix-normal prior and a hierarchical prior, which corresponds to an arbitrary scale mixture of normals. We establish posterior consistency for both these priors under standard regularity assumptions, when the dimension p of the VAR model grows with the sample size n (but still remains smaller than n). A special case corresponds to a shrinkage prior that introduces (group) sparsity in the columns of the model coefficient matrices. The performance of the model estimates are illustrated on synthetic and real macroeconomic datasets. Supplementary materials for this article are available online.

description: A crisis in management has led to the appearance of Authentic leadership.
The aim of this work is to determine the characteristics of Authentic leadership in educational institutions and to respond to the question as to whether authentic leaders are satisfied with their job. The third aim is to determine differences among the researched regions. The sample included 227 randomly selected directors from primary and secondary schools in Serbia, Montenegro and the Republika Srpska. The research used an ALQ questionnaire for the estimation of leadership behaviour. Descriptions for the results prediction and multiple linear regressions were used. A multivariance analysis of variance was used to compare the groups. The research results showed that every fourth director is an authentic leader. Authentic leadership has a significant influence on job satisfaction through two aspects: internalised perspective and balanced processing. There are no differences in Authentic leadership in the researched areas. The results could be useful for educational institutions in countries where the research was conducted. Further research could be carried out in other countries while cultural differences should be taken into account. One limiting factor consists of the fact that the analysed data are obtained only from school directors. Leaders of educational institutions should provide management through the development of their own authenticity and the authenticity of their followers. The characteristics of Authentic leadership were reviewed and tested practically in the West-Balkan environment.

description: High-dimensional compositional data arise naturally in many applications such as metagenomic data analysis. The observed data lie in a high-dimensional simplex, and conventional statistical methods often fail to produce sensible results due to the unit-sum constraint. In this article, we address the problem of covariance estimation for high-dimensional compositional data and introduce a composition-adjusted thresholding (COAT) method under the assumption that the basis covariance matrix is sparse. Our method is based on a decomposition relating the compositional covariance to the basis covariance, which is approximately identifiable as the dimensionality tends to infinity. The resulting procedure can be viewed as thresholding the sample centered log-ratio covariance matrix and hence is scalable for large covariance matrices. We rigorously characterize the identifiability of the covariance parameters, derive rates of convergence under the spectral norm, and provide theoretical guarantees on support recovery. Simulation studies demonstrate that the COAT estimator outperforms some existing optimization-based estimators. We apply the proposed method to the analysis of a microbiome dataset to understand the dependence structure among bacterial taxa in the human gut.

Post-explosion positive jet-feedback activity in inner ejecta of core collapse supernovae

description: We conduct three-dimensional hydrodynamical simulations of weak jets that we launch into a core collapse supernovae (CCSNe) ejecta half an hour after the explosion and find that the interaction of the fast jets with the CCSN ejecta creates high pressure zones that induce a backflow that results in mass accretion onto the newly born neutron star. In cases of weak jets, a total power of 10^45-10^46 erg, the backflow mass accretion might power up to an order of magnitude more energetic jets. In total, the jets of the two post-explosion jet-launching episodes have enough energy to influence the morphology of the very inner ejecta, a mass of 0.1 M_O. Our results imply that in some, probably a minority of, CCSN remnants the very inner regions might display a bipolar structure that results from post-explosion weak jets. The regions outside this part might display the morphology of jittering jets.

description: We grow $^{28}$Si/SiGe heterostructures by reduced-pressure chemical vapor deposition and terminate the stack without an epitaxial Si cap but with an amorphous Si-rich layer obtained by exposing the SiGe barrier to dichlorosilane at 500 °C. As a result, $^{28}$Si/SiGe heterostructure field-effect transistors feature a sharp semiconductor/dielectric interface and support a two-dimensional electron gas with enhanced and more uniform transport properties across a 100 mm wafer. At T = 1.7 K we measure a high mean mobility of (1.8$\pm$0.5)$\times$10$^5$ cm$^2$/Vs and a low mean percolation density of (9$\pm$1)$\times$10$^{10}$ cm$^{-2}$. From the analysis of Shubnikov-de Haas oscillations at T = 190 mK we obtain a long mean single particle relaxation time of (8.1$\pm$0.5) ps, corresponding to a mean quantum mobility and quantum level broadening of (7.5$\pm$0.6)$\times$10$^4$ cm$^{2}$/Vs and (40$\pm$3) $μ$eV, respectively, and a small mean Dingle ratio of (2.3$\pm$0.2), indicating reduced scattering from long range impurities and a low-disorder environment for hosting high-performance spin-qubits.

description: This study attempts to validate process management scale using rigorous validation procedures. An adapted questionnaire comprising 77 items was administered to faculty members in two public universities in Nigeria. The data gathered were analyzed using exploratory factor analysis and confirmatory factor analysis with SPSS 20.0 and SmartPLS 3.1.2 respectively. The findings of this study shows that process management is a third order reflective model with multidimensional constructs. The two dimension of process management administrative process and academic process has four and five dimensions respectively. The process management scale will therefore facilitate the identifications of elements that influence the effectiveness of higher education. The practical implications and methodological limitations are discussed.

description: Given a way to evaluate an unknown polynomial with integer coefficients, we present new algorithms to recover its nonzero coefficients and corresponding exponents. As an application, we adapt this interpolation algorithm to the problem of computing the exact quotient of two given polynomials. These methods are efficient in terms of the bit-length of the sparse representation, that is, the number of nonzero terms, the size of coefficients, the number of variables, and the logarithm of the degree. At the core of our results is a new Monte Carlo randomized algorithm to recover a polynomial $f(x)$ with integer coefficients given a way to evaluate $f(θ) \bmod m$ for any chosen integers $θ$ and $m$. This algorithm has nearly-optimal bit complexity, meaning that the total bit-length of the probes, as well as the computational running time, is softly linear (ignoring logarithmic factors) in the bit-length of the resulting sparse polynomial. To our knowledge, this is the first sparse interpolation algorithm with soft-linear bit complexity in the total output size. For polynomials with integer coefficients, the best previously known results have at least a cubic dependency on the bit-length of the exponents.

description: The half-quantized Hall conductance is characteristic of quantum systems with parity anomaly. Here we investigate topological and transport properties of a class of parity anomalous semimetals, in which massive Dirac fermions coexist with massless Dirac fermions in momentum space or real space, and uncovered a distinct bulk-edge correspondence that the half-quantized Hall effect is realized via the bulk massless Dirac fermions while the nontrivial Berry curvature is provided by the massive Dirac fermions. The spatial distribution of the edge current decays away from the boundary in a power law instead of an exponential law in integer quantum Hall effect. We further address physical relevance of parity anomalous semimetal to three-dimensional semi-magnetic topological insulators and two-dimensional photonic crystals.

description: We perform spectral fitting for a set of O-type stars based on self-consistent wind solutions, which provide mass-loss rate and velocity profiles directly derived from the initial stellar parameters. The great advantage of this self-consistent spectral fitting is therefore the reduction of the number of free parameters to be tuned. Self-consistent values for the line-force parameters (k,alpha,delta) and subsequently for the mass-loss rate and terminal velocity are provided by the m-CAK prescription introduced in Paper I, updated in this work with improvements such as a temperature structure for the wind, self-consistently evaluated from the line-acceleration. Synthetic spectra are calculated using the radiative transfer code FASTWIND, replacing the classical beta-law for our new calculated velocity profiles. We found that self-consistent m-CAK solutions provide values for theoretical mass-loss rates on the order of the most recent predictions of other studies. From here, we generate synthetic spectra with self-consistent hydrodynamics to fit and obtain a new set of stellar and wind parameters for our sample of O-type stars whose spectra was taken with the high resolution echelle spectrograph HERMES (R=85000). We find a satisfactory global fit for our observations, with good accuracy for photospheric He I and He II lines and a quite acceptable fit for H lines. Although this self-consistent spectral analysis is currently constrained in the optical wavelength range only, this is an important step towards the determination of stellar and wind parameters without using a beta-law. Given these results, we expect that the values introduced here should be helpful for future studies about the stars constituting this sample, together with the prospective that the m-CAK self-consistent prescription be extended to numerous studies about massive stars in future.

Huichol

description: The Huichol are native inhabitants of what are now the Mexican States of Jalisco, Nayarit, Zacatecas, and Durango. In 1722 the Huichol were conquered by the Spanish, after which Franciscan Missionaries arrived and nominally converted the Huichol to Christianity before leaving the area in the mid 1800’s (Lumholtz, 1973:22). Missionaries left a varying degree of Christian influence across Huichol communities, but at the time this entry focuses on (around 1890) native beliefs were still held and traditional customs and ceremonies were still practiced; the Huichol religion would become more syncretic with Christianity in the 20th century. To the Huichol, religion does not constitute a separate sphere of life; there is no distinction between sacred and everyday life. As such, this entry considers the Huichol religious group to be coterminous with the society itself. Religious practitioners known as shamans are trained in healing, divining, and priestly activities, and communicate with the supernatural. In addition to the spirits of the dead, the Huichol pantheon contains a variety of deities representing personified natural phenomenon such as fire, air, earth, and water. Fire (also known as Grandfather) is said to be the greatest and oldest, existing before the sun (Father). Fire is associated with deer and peyote. The Huichol “petition the deities for sun and rain for the crops, successful deer hunts, fertility, good health, and protection from the dangers of the natural and supernatural worlds” (Schaefer, 2016). The Huichol have an annual cycle of feasts and ceremonies associated with the propitiation of gods, and connected to the agricultural cycle and environmental phenomenon such as rain. Most importantly is the annual journey to sacred (known to the Huichol as híkul͂i), peyote land, where the plant is harvested and later utilized in rituals and to communicate with the gods.

description: In the realm of massive stars, strong binary interaction is commonplace. One extreme case are overcontact systems, which is expected to be part of the evolution of all stars evolving towards a merger, and is hypothesized to play a role in the formation of binary black holes. However, important simplifications are made to model the evolution of overcontact binaries, namely that tidal or rotational deformation is frequently ignored. Yet, both observation and theory show that overcontact stars are heavily tidally deformed, leaving a potentially important effect on the outer layers unaccounted for in models. In this work we develop the methodology to represented tidally deformed stars. Using numerical methods, we compute the structure correction factors to the 1D spherical stellar structure equations due to the binary Roche potential, and compare them to existing results and the structure corrections of single rotating stars. We implement the new structure correction factors into the stellar evolution code MESA and explore several case studies. We compare the differences between our simulations when no rotation is included, when we treat rotation using single star corrections (i.e. only accounting for centrifugal deformation) or when we use tidal deformation. We find that ignoring rotation in deformed detached eclipsing binaries can produce a radius discrepancy of up to 5%. The difference between tidal and single star centrifugal distortion models is more benign at 1%, showing that single rotating star models are a suitable approximation of tidally deformed stars in a binary system. In overcontact configurations, we find a similar 5% variation in surface properties as a result of tidal distortion with respect to non-rotating models, showing that it is inappropriate to model binary stars that fill their Roche lobe significantly, as non-rotating.

Nonadiabatic instanton rate theory beyond the golden-rule limit

description: Fermi's golden rule describes the leading-order behaviour of the reaction rate as a function of the diabatic coupling. Its asymptotic $(\hbar \rightarrow 0)$ limit is the semiclassical golden-rule instanton rate theory, which rigorously approximates nuclear quantum effects, lends itself to efficient numerical computation and gives physical insight into reaction mechanisms. However the golden rule by itself becomes insufficient as the strength of the diabatic coupling increases, so higher-order terms must be additionally considered. In this work we give a first-principles derivation of the next-order term beyond the golden rule, represented as a sum of three components. Two of them lead to new instanton pathways that extend the golden-rule case and, among other factors, account for the effects of recrossing on the full rate. The remaining component derives from the equilibrium partition function and accounts for changes in potential energy around the reactant and product wells due to diabatic coupling. The new semiclassical theory demands little computational effort beyond a golden-rule instanton calculation. It makes it possible to rigorously assess the accuracy of the golden-rule approximation and sets the stage for future work on general semiclassical nonadiabatic rate theories.

description: This work proposes new inference methods for a regression coefficient of interest in a (heterogenous) quantile regression model. We consider a high-dimensional model where the number of regressors potentially exceeds the sample size but a subset of them suffices to construct a reasonable approximation to the conditional quantile function. The proposed methods are (explicitly or implicitly) based on orthogonal score functions that protect against moderate model selection mistakes, which are often inevitable in the approximately sparse model considered in the present article. We establish the uniform validity of the proposed confidence regions for the quantile regression coefficient. Importantly, these methods directly apply to more than one variable and a continuum of quantile indices. In addition, the performance of the proposed methods is illustrated through Monte Carlo experiments and an empirical example, dealing with risk factors in childhood malnutrition.

How do Magnetic Field Models Affect Astrophysical Limits on Light Axion-like Particles? An X-ray Case Study with NGC 1275

description: Axion-like particles (ALPs) are a well-motivated extension to the standard model of particle physics, and X-ray observations of cluster-hosted AGN currently place the most stringent constraints on the ALP coupling to electromagnetism, $g_{a γ}$, for very light ALPs ($m_a\lesssim10^{-11}$ eV). We revisit limits obtained by Reynolds et al. (2020) using Chandra X-ray grating spectroscopy of NGC 1275, the central AGN in the Perseus cluster, examining the impact of the X-ray spectral model and magnetic field model. We also present a new publicly available code, ALPro, which we use to solve the ALP propagation problem. We discuss evidence for turbulent magnetic fields in Perseus and show that it can be important to resolve the magnetic field structure on scales below the coherence length. We re-analyse the NGC 1275 X-ray spectra using an improved data reduction and baseline spectral model. We find the limits are insensitive to whether a partially covering absorber is used in the fits. At low $m_a$ ($m_a\lesssim10^{-13}$ eV), we find marginally weaker limits on $g_{a γ}$ (by $0.1-0.3$ dex) with different magnetic field models, compared to Model B from Reynolds et al. (2020). A Gaussian random field (GRF) model designed to mimic $\sim50$ kpc scale coherent structures also results in only slightly weaker limits. We conclude that the existing Model B limits are robust assuming that $β_{\rm pl}\approx100$, and are insensitive to whether cell-based or GRF methods are used. However, astrophysical uncertainties regarding the strength and structure of cluster magnetic fields persist, motivating high sensitivity RM observations and tighter constraints on the radial profile of $β_{\rm pl}$.
