description: During the gravitational core collapse of a massive progenitor star which may give rise to at least a class of gamma-ray bursts (GRBs) associated with supernovae, a stellar core rapidly passes through a short yet important phase of neutronization, producing a huge amount of energetic neutrinos and photons which contribute to the total pressure within the progenitor core. The collection of neutrinos, photons and gas materials together may be approximated as a fluid with a polytropic index $γ=4/3$ under the action of self-gravity. With a substantial generalization and using analytical and numerical methods (Lou & Cao 2008), we recently constructed and examined various self-similar solutions to describe collapses, rebound shocks and flows systematically in a $γ=4/3$ polytropic gas mixture with spherical symmetry, and compare our results with those of Goldreich & Weber (1980). It is also possible to construct central void solutions without or with shocks. Various features and characteristics of this nonlinear relativistically hot gas dynamics, including asymptotic and exact solutions, are presented. This more general polytropic model analysis provides the dynamic basis of understanding the evolution of rebound shocks in supernovae (SNs) and the results may be also utilized to benchmark hydrodynamic simulations.

Tests of determinants of optimal capital structure
Creators: name: Portman, Nicholas Francis
Publisher: name: University of British Columbia
Year: 2010

description: This paper provides an examination of the relationship between capital structure and a number of firm characteristics. A synopsis of the theory and evidence on capital structure to date is provided. A model is developed which posits that capital structure is positively related to liquidity, firm size, the relative amounts of subordinated and priorized debt, and negatively related to operating leverage, sales variability, and bankruptcy costs. Tests of the model were performed in a regression context, with the logarithm of the debt-to-equity ratio as the dependent variable. The characteristics used as independent variables were degree of operating leverage, variance of sales, industry class, firm size, the proportion of secured to unsecured debt, a liquidity measure (cash to total assets), and a number of proxies for operating leverage (accounts receivable, inventory and net plant, to total assets). Dummy variables were introduced to check for the influence of industry class, convertible debt and preferreds on capital structure. Capital structure was found to be significantly negatively related to liquidity, industry class, operating leverage, and significantly positively related to the ratio subordinated to other long term debt. Size and sales variability were found to have no influence on financial leverage. Firms which had issued preferred stock had higher debt ratios. Convertible debt tended to act like equity.

description: We propose a method for computing numerically integrals defined via $i ε$ deformations acting on single-pole singularities. We achieve this without an explicit analytic contour deformation. Our solution is then used to produce precise Monte Carlo estimates of multi-scale multi-loop integrals directly in Minkowski space. We corroborate the validity of our strategy by presenting several examples ranging from one to three loops. When used in connection with four-dimensional regularization techniques, our treatment can be extended to ultraviolet and infrared divergent integrals.

description: In the present work, we study the production problem of the charmed baryon $Λ_c(2860)^+$ at $\overline{\mbox{P}}$ANDA. With the $J^P=\frac{3}{2}^+$ assignment to $Λ_c(2860)^+$, an effective Lagrangian approach is adopted to calculate the cross section of $p\bar{p} \to Λ_c^-Λ_c(2860)^+$. The Dalitz plot analysis and the $D^0p$ invariant mass spectrum distribution are also given for the $p\bar{p} \to Λ_c^-Λ_c(2860)^+ \to Λ_c^-pD^0$ process. The numerical results show that the total cross section may reach up to about 10 $ μ$b. With the designed luminosity of $\overline{\mbox{P}}$ANDA ($2\times10^{32}~\mbox{cm}^{-2}\mbox{s}^{-1}$), about $ 10^8 $ $Λ_c(2860)$ events can be expected per day by reconstructing the final $ pD^0 $.

description: Objective: Neuropsychological assessment (NP) feedback helps patients and caregivers understand assessment results to maximise their utility and impact in everyday life. Yet feedback practices are inconsistent and there are no evidence-based guidelines for how feedback should be most effectively delivered. The aim of our study was to develop a psychometrically sound feedback competency checklist, the Psychology Competency Assessment Tool – Feedback (PsyCET-F), for use in research, training, and clinical settings. Method: The Delphi method of expert consensus was used to establish checklist items that clearly described competencies important for NP feedback. To examine the inter-rater reliability of the checklist, two experienced neuropsychologists rated the competencies demonstrated by trainee neuropsychologists across four feedback sessions. Results: After two Delphi rounds, consensus was reached on the 20-item checklist. Consensus was defined as at least 80% agreement amongst the panel of 20 experts. Four item categories resulted from the Delphi: (a) Opening the Session; (b) Applying Specific Feedback Techniques; (c) Engagement, Collaboration, and Alliance; and (d) Structuring and Ending the Session. Inter-rater reliability was moderate (κW = 0.79, p <.001, 80.52% agreement) when using a simple coding system, coded as Beginner, Intermediate, Competent, and Skilful; and strong (κW = 0.82, p <.001) when competency level was coded using an 8-point, detailed coding method. Conclusions: The PsyCET-F is psychometrically sound and fit-for-purpose for measuring competencies in giving NP feedback. It can be used in the training of clinicians to develop effective feedback skills. International benchmarking and usability testing will be conducted in a future study.

description: In this work it is shown how to obtain, in a simple way, localized (non- diffractive) subluminal pulses as exact analytic solutions to the wave equations. These new ideal subluminal solutions, which propagate without distortion in any homogeneous linear media, are herein obtained for arbitrarily chosen frequencies and bandwidths, avoiding in particular any recourse to the non-causal components so frequently plaguing the previously known localized waves. The new solutions are suitable superpositions of --zeroth-order, in general-- Bessel beams, which can be performed either by integrating with respect to (w.r.t.) the angular frequency, or by integrating w.r.t. the longitudinal wavenumber: Both methods are expounded in this paper. The first one appears to be powerful enough; we study the second method as well, however, since it allows dealing even with the limiting case of zero-speed solutions (and furnishes a new way, in terms of continuous spectra, for obtaining the so-called "Frozen Waves", so promising also from the point of view of applications). We briefly treat the case, moreover, of non-axially symmetric solutions, in terms of higher order Bessel beams. At last, particular attention is paid to the role of Special Relativity, and to the fact that the localized waves are expected to be transformed one into the other by suitable Lorentz Transformations. The analogous pulses with intrinsic finite energy, or merely truncated, will be constructed in another paper. In this work we fix our attention especially on electromagnetism and optics: but results of the present kind are valid whenever an essential role is played by a wave-equation (like in acoustics, seismology, geophysics, gravitation, elementary particle physics, etc.)

description: In this Colloquium recent advances in the field of quantum heat transport are reviewed. This topic has been investigated theoretically for several decades, but only during the past twenty years have experiments on various mesoscopic systems become feasible. A summary of the theoretical basis for describing heat transport in one-dimensional channels is first provided. Then the main experimental investigations of quantized heat conductance due to phonons, photons, electrons, and anyons in such channels are presented. These experiments are important for understanding the fundamental processes that underly the concept of a heat conductance quantum for a single channel. Then an illustration on how one can control the quantum heat transport by means of electric and magnetic fields, and how such tunable heat currents can be useful in devices is given. This lays the basis for realizing various thermal device components such as quantum heat valves, rectifiers, heat engines, refrigerators, and calorimeters. Also of interest are fluctuations of quantum heat currents, both for fundamental reasons and for optimizing the most sensitive thermal detectors; at the end of the review the status of research on this intriguing topic is given.

description: In a quantum theory of gravity the gravitational Wilson loop, defined as a suitable quantum average of a parallel transport operator around a large near-planar loop, provides important information about the large-scale curvature properties of the geometry. Here we shows that such properties can be systematically computed in the strong coupling limit of lattice regularized quantum gravity, by performing a local average over rotations, using an assumed near-uniform measure in group space. We then relate the resulting quantum averages to an expected semi-classical form valid for macroscopic observers, which leads to an identification of the gravitational correlation length appearing in the Wilson loop with an observed large-scale curvature. Our results suggest that strongly coupled gravity leads to a positively curved (De Sitter-like) quantum ground state, implying a positive effective cosmological constant at large distances.

description: The principal objective of this work is to report on the power coupled to a tungsten target in the Proto-MPEX device during oblique injection of a microwave beam (< 70 kW at 28 GHz) into a high-power (~100 kW at 13.56 MHz) over-dense (n_e>1E10^19 m^(-3)) deuterium helicon plasma column. The experimental setup, electron heating system, electron heating scheme, and IR thermographic diagnostic for quantifying the power transport is described in detail. It is demonstrated that the power transported to the target can be effectively controlled by adjusting the magnetic field profile. Using this method, heat fluxes up to 22 MWm-2 and power transport efficiencies in the range of 17-20% have been achieved using 70 kW of microwave power. It is observed that most of the heat flux is confined to a narrow region at the plasma periphery. Ray-tracing calculations are presented which indicate that the power is coupled to the plasma electrons via an O-X-B mode conversion process. Calculations indicate that the microwave power is absorbed in a single pass at the plasma periphery via collisions and in the over-dense region via 2nd harmonic cyclotron resonance of the electron Bernstein wave. The impact of these results is discussed in the context of MPEX.

description: Objective: Historically, naming has been assessed with visual object naming; however, we have found that auditory description naming significantly enhances lateralization and localization of dysfunction. We previously published auditory naming (ANT) and complementary Visual Naming Tests (VNT) for young adults, and recently developed these measures for children (ages 6–15 years) and older adults (ages 56–100 years). Here, we update the original stimuli and more rigorously norm the tests for ages 16–55, addressing prior limitations. Methods: Test stimuli were selected based on item characteristics and preliminary screening, eliminating those with less than 90% name agreement. A sample of 178 healthy individuals ages 16–55 years were administered the updated ANT and VNT, and other standardized measures, either in person (n = 114) or via telehealth (n = 64). Results: With no effect of age, yet a significant influence of education, education-based normative data are provided for accuracy, tips-of-the-tongue (i.e. delayed, accurate responses plus correct responses following phonemic cueing), and an aggregate Summary Score. Internal and test–retest reliability coefficients were reasonable (.67–.90). Conclusions: These measures provide updated and improved naming assessment for ages 16–55 years, contributing to a contiguous set of naming tests for school-aged children through elderly adults. Compared to the original ANT and VNT, these measures were designed to have stimuli longevity, and offer reduced item burden and evidence-based recommendations for performance measures with the greatest clinical sensitivity. The addition of these measures enables continuity in assessment across the age span, facilitating longitudinal assessment related to disease progression or therapeutic intervention.

description: "Basta driver, sweet lover." A short cheesy line makes them known as the roads' casanova, the nicest sweet talker, generous people, and someone who will ensure the passengers' safety. However, behind the most adorable smile on their lips is the underlying reason for their every sweat and hard work, and because of the recent events, everything changed. Coronavirus Disease (COVID-19) has been the world's biggest problem encountered during the 21st Century. Thus, the study utilizes Interpretative Phenomenological Analysis (IPA) with 10 participants in the study. Furthermore, it aims to explore the lived experiences of tricycle drivers during the pandemic, specifically: (1) to describe the lived experiences of the respondents, (2) to describe the challenges faced of the respondents, and (3) to describe the ways and means on how they cope up with the situation. Moreover, based on the study, the findings are the following: tricycle drivers experienced the pandemic's positive and negative effects that teach them things that they must do if it happens again. The respondents faced challenges and difficulties brought by the pandemic and created their ways to deal with it. They also learn different coping mechanisms during the pandemic that helped them adjust and face the COVID-19 pandemic.

description: We show that the Euclidean Kerr-NUT-(A)dS metric in $2m$ dimensions locally admits $2^m$ hermitian complex structures. These are derived from the existence of a non-degenerate closed conformal Killing-Yano tensor with distinct eigenvalues. More generally, a conformal Killing-Yano tensor, provided its exterior derivative satisfies a certain condition, algebraically determines $2^m$ almost complex structures that turn out to be integrable as a consequence of the conformal Killing-Yano equations. In the complexification, these lead to $2^m$ maximal isotropic foliations of the manifold and, in Lorentz signature, these lead to two congruences of null geodesics. These are not shear-free, but satisfy a weaker condition that also generalizes the shear-free condition from 4-dimensions to higher-dimensions. In odd dimensions, a conformal Killing-Yano tensor leads to similar integrable distributions in the complexification. We show that the recently discovered 5-dimensional solution of Lu, Mei and Pope also admits such integrable distributions, although this does not quite fit into the story as the obvious associated two-form is not conformal Killing-Yano. We give conditions on the Weyl curvature tensor imposed by the existence of a non-degenerate conformal Killing-Yano tensor; these give an appropriate generalization of the type D condition on a Weyl tensor from four dimensions.

description: Nonlinear perturbation of Fuchsian systems are studied in a region including two singularities. It is proved that such systems are generally not analytically equivalent to their linear part (they are not linearizable) and the obstructions are found constructively, as a countable set of numbers. Furthermore, assuming a polynomial character of the nonlinear part, it is shown that there exists a unique formal "correction" of the nonlinear part so that the "corrected" system is formally linearizable. Normal forms of these systems are found, providing also their classification.
The Use and Limitations of Import Coverage Statistics

description: Excerpts from the report: To conclude, import coverage statistics, when used alone, are not an adequate indicator for assessing external economic position or for the more specific task of determining potential for the importation of U.S. agricultural products. They need to be supplemented by other, possible more pertinent, economic information. For example, information on historical balance-of-payments performance may give some indication as to whether a current change in the level of external economic activity is cyclical or secular; information as to total international liquidity available to the country will more nearly equate potential resources to potential needs; domestic economic data may indicate something about forces which underlie, and perhaps cause, balance-of-payments disequilibrium. Import coverage statistics may usefully contribute, however, to the making of temporal comparisons for a particular country. If import coverage improves over a certain period, it may indicate that a country has successfully reduced import levels and/or has earned enough additional foreign exchange to be able to maintain or increase present import levels. If we also know, for example, that import regulations have not been made more restrictive and/or discriminatory trade arrangements have not been extended, and that external liquidity other than reserves has not been impaired or reduced, then an increase in months of import coverage may indeed be indicative of increased import potential. Import coverage statistics can, with some improvement in computation (e.g., seasonal adjustment), be an extremely useful analytical tool when used in conjunction with other economic data.

description: We consider a longitudinal expansion of a one-dimensional gas of hard-core bosons suddenly released from a trap. We show that the broken translational invariance in the initial state of the system is encoded in correlations between the bosonic occupation numbers in the momentum space. The correlations are protected by the integrability and exhibit no relaxation during the expansion.

description: Family is the most basic unit of society, and the foundation of it is the parents, marriage, and offspring. Everyone longs for a place to call home and a healthy family both in mind and body relationship. Generally, people’s view of complete families has married parents with children. Even so, the case is not always like that. Broken families are not uncommon; rather, it is familiar and often encountered around us. This study’s primary goal is to assess the lived experiences of students from broken families amidst the pandemic, specifically, it sought the following objectives: (1) to describe the positive experiences of students from broken families, (2) to describe the challenges of the students from broken families experience and why do they consider those as challenges, (3) to describe the effects on academic performance of the students coming from broken families. The study utilized Interpretative Phenomenology Analysis (IPA) with the 10 participants ages of 15 to 24 years old from a broken family. Based on the study, the findings are the following: (1) Most of the students from broken families are greatly challenged by financial, emotional, mental, social, and behavioral problems that contribute to their poor academic performance. (2) Most of the students that have divorced (separated) parents are inattentive and limited. They rarely provide time, care, and financial support for student’s daily needs and academic fees. (3) Students from broken families cope with being independent and optimistic in their situation. (4) Students from broken families gain positive experiences despite the traumatic family background, especially personal growth and building stronger relationships.

Conclusions: These measures provide updated and improved naming assessment for ages 16–55 years, contributing to a contiguous set of naming tests for school-aged children through elderly adults. Compared to the original ANT and VNT, these measures were designed to have stimuli longevity, and offer reduced item burden and evidence-based recommendations for performance measures with the greatest clinical sensitivity. The addition of these measures enables continuity in assessment across the age span, facilitating longitudinal assessment related to disease progression or therapeutic intervention.

description: We derive the classical gravitational radiation from an aligned spin binary black hole on \textit{closed} orbits, using a dictionary built from the 5-point QFT scattering amplitude of two massive particles exchanging and emitting a graviton. We show explicitly the agreement of the transverse-traceless components of the radiative linear metric perturbations -- and the corresponding gravitational wave energy flux -- at future null infinity, derived from the scattering amplitude and those derived utilizing an effective worldline action in conjunction with multipolar post-Minkowskian matching. At the tree-level, this result holds at leading orders in the black holes' velocities and up to quadratic order in their spins. At sub-leading order in black holes' velocities, we demonstrate a matching of the radiation field for quasi-circular orbits in the no-spin limit. At the level of the radiation field, and to leading order in the velocities, there exists a one-to-one correspondence between the binary black hole mass and current quadrupole moments, and the scalar and linear-in-spin scattering amplitudes, respectively. Therefore, we show explicitly that waveforms, needed to detect gravitational waves from \textit{inspiraling} binary black holes, can be derived consistently, to the orders considered, from the classical limit of quantum \textit{scattering} amplitudes.

description: In this paper we classify the laws of three-dimensional and four-dimensional nilpotent Jordan algebras over the field of complex numbers. We describe the irreducible components of their algebraic varieties and extend contractions and deformations among them. In particular, we prove that J2 and J3 are irreducible and that J4 is the union of the Zariski closures of two rigid Jordan algebras.

description: We describe how the James Webb Space Telescope (JWST) Near-Infrared Spectrograph's (NIRSpec's) detectors will be read out, and present a model of how noise scales with the number of multiple non-destructive reads sampling-up-the-ramp. We believe that this noise model, which is validated using real and simulated test data, is applicable to most astronomical near-infrared instruments. We describe some non-ideal behaviors that have been observed in engineering grade NIRSpec detectors, and demonstrate that they are unlikely to affect NIRSpec sensitivity, operations, or calibration. These include a HAWAII-2RG reset anomaly and random telegraph noise (RTN). Using real test data, we show that the reset anomaly is: (1) very nearly noiseless and (2) can be easily calibrated out. Likewise, we show that large-amplitude RTN affects only a small and fixed population of pixels. It can therefore be tracked using standard pixel operability maps.

description: Software developers are turning to vlogs (video blogs) to share what a day is like to walk in their shoes. Through these vlogs developers share a rich perspective of their technical work as well their personal lives. However, does the type of activities portrayed in vlogs differ from activities developers in the industry perform? Would developers at a software company prefer to show activities to different extents if they were asked to share about their day through vlogs? To answer these questions, we analyzed 130 vlogs by software developers on YouTube and conducted a survey with 335 software developers at a large software company. We found that although vlogs present traditional development activities such as coding and code peripheral activities (11%), they also prominently feature wellness and lifestyle related activities (47.3%) that have not been reflected in previous software engineering literature. We also found that developers at the software company were inclined to share more non-coding tasks (e.g., personal projects, time spent with family and friends, and health) when asked to create a mock-up vlog to promote diversity. These findings demonstrate a shift in our understanding of how software developers are spending their time and find valuable to share publicly. We discuss how vlogs provide a more complete perspective of software development work and serve as a valuable source of data for empirical research.

The influence of direct $D$-meson production to the determination on the nucleon strangeness asymmetry via dimuon events in neutrino experiments

description: Experimentally, the production of oppositely charged dimuon events by neutrino and anti-neutrino deep inelastic scattering (DIS) is used to determine the strangeness asymmetry inside a nucleon. Here we point out that the direct production of $D$-meson in DIS may make substantial influence to the measurement of nucleon strange distributions. The direct $D$-meson production is via the heavy quark recombination (HQR) and via the light quark fragmentation from perturbative QCD (LQF-P). To see the influence precisely, we compute the direct $D$-meson productions via HQR and LQF-P quantitatively and estimate their corrections to the analysis of the strangeness asymmetry. The results show that HQR has stronger effect than LQF-P does, and the former may influence the experimental determination of the nucleon strangeness asymmetry.

description: People classify single parents as a solo parent is separated by their partners and raise their child dependently. Aside from this, they also manage the household and carry the burden of supporting the child's development. Thus, despite being one of the predominantly conservative countries, the Philippines cannot change the constructed perspective that society conforms to single parents' condition. These perspectives devalued solo parents' worth and changed the sense of purpose and responsibility in their household. The hardships that they do are less to be recognized and appear to be downgraded. Further, this study aims to Thus, this study aims to describe the lived experiences, challenges and coping mechanisms of single moms during the Coronavirus Disease (COVID-19) pandemic. Utilizing Interpretative Phenomenology Analysis (IPA) with the 10 participants who met the criteria. Moreover, the implications of the study were discussed, and recommendations were suggested.

Observational Tests of Modified Gravity
Creators: name: Jain, Bhuvnesh
name: Zhang, Pengjie
Publisher: name: arXiv
Year: 2007
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: Modified gravity theories have richer observational consequences for large-scale structure than conventional dark energy models, in that different observables are not described by a single growth factor even in the linear regime. We examine the relationships between perturbations in the metric potentials, density and velocity fields, and discuss strategies for measuring them using gravitational lensing, galaxy cluster abundances, galaxy clustering/dynamics and the ISW effect. We show how a broad class of gravity theories can be tested by combining these probes. A robust way to interpret observations is by constraining two key functions: the ratio of the two metric potentials, and the ratio of the Gravitational ``constant'' in the Poisson equation to Newton's constant. We also discuss quasilinear effects that carry signatures of gravity, such as through induced three-point correlations. Clustering of dark energy can mimic features of modified gravity theories and thus confuse the search for distinct signatures of such theories. It can produce pressure perturbations and anisotropic stresses, which breaks the equality between the two metric potentials even in general relativity. With these two extra degrees of freedom, can a clustered dark energy model mimic modified gravity models in all observational tests? We show with specific examples that observational constraints on both the metric potentials and density perturbations can in principle distinguish modifications of gravity from dark energy models. We compare our result with other recent studies that have slightly different assumptions (and apparently contradictory conclusions).

Comptabilité d’inflation en France : Comparison avec l’approche canadienne
Creators: name: Cormier, D.
Publisher: name: University of British Columbia
Year: 2010

description: L'objet de cette dissertation etait de mettre en relief l'approche frangaise avec l'approche canadienne relative a la comptabilite d'inflation. Dans un premier temps, les lois francaises de reevaluation libre et legale des bilans ont ete analysees. Il ressort de la reevaluation libre qu'elle n'est que tres peu utilisee. Le fait que l'operation soit peu avan-tageuse fiscalement et qu'elle ne soit pas d'un grand secours dans la negotiation des prets expliquent cet etat de chose. La reevaluation libre a ete remplacee par la reevaluation legale de 1976 a 1979 mais depuis, on y est revenu. Pour ce qui est de la reevaluation legale, la valeur d'utility servant de base a la reevaluation est tres subjective; le caractere ponctuel de l'operation de reevaluation gene l'obtention d'une information sincere et objective. Une autre fai-blesse de la reevaluation legale est l'absence de corrections sur les stocks. Finalement, d'apres un sondage effectue aupres de firmes de comptables, seulement 1% des entreprises etaient obligees de proceder a la reevaluation et seulement 1.5% des entreprises non astreintes a la reevaluation ont choisi de s'y preter. La neutrality fiscale est la raison majeure expliquant l'indifference des entreprises. Dans un deuxieme temps, l'Avis des experts comptables (de 1981) a ete compare au chapitre 4510 du Manuel de l'ICCA. Certaines faiblesses de l'Avis ont ete ressorties: l'utilisation du cout d'origine indexe pour fins de calcul de la charge d'amortissement et de 1'evaluation des immobilisations alors que l'on utilise les prix d'entree courants pour les stocks represente une position difficilement defendable. Aussi, le fait de ne pas reconnaitre les plus-values non realisees au niveau du profit d'entreprise s'explique mal. Enfin, les moyens suggeres pour tenir compte de l1incidence de la structure financiere donnent des resultats tres differents et peuvent sou-vent consister en des outils mediocres. On peut conclure que les positions de la France aussi bien avec la reevaluation (libre et legale) qu'avec l'Avis des experts comptables souffrent d'un certain manque de logique et de coherence.

description: Hadronic signals of new-physics origin at the Large Hadron Collider can remain hidden within the copiously produced hadronic jets. Unveiling such signatures require highly performant deep-learning algorithms. We construct a class of Graph Neural Networks (GNN) in the message-passing formalism that makes the network output infra-red and collinear (IRC) safe, an important criterion satisfied within perturbative QCD calculations. Including IRC safety of the network output as a requirement in the construction of the GNN improves its explainability and robustness against theoretical uncertainties in the data. We generalise Energy Flow Networks (EFN), an IRC safe deep-learning algorithm on a point cloud, defining energy weighted local and global readouts on GNNs. Applying the simplest of such networks to identify top quarks, W bosons and quark/gluon jets, we find that it outperforms state-of-the-art EFNs. Additionally, we obtain a general class of graph construction algorithms that give structurally invariant graphs in the IRC limit, a necessary criterion for the IRC safety of the GNN output.
