Bedside clinical skills teaching using (PAL-SBE): Students' perception as instructor and learner.
Creators: name: Abdelrahman, Nada Hassan Ahmed
Publisher: name: F1000 Research Limited
Year: 2024

description: Background

Introduction

Teaching clinical skills is an essential competency learned as an apprenticeship from generation to generation. Clinical skills are a declining practice for multiple reasons, including time constraints, enhanced technology-based diagnosis and icon patient "i-Patient" .1 We introduced a new Simulation project in our college whereby students created

a Peer-assisted Learning-simulation-based education (PAL-SBE). This paper reflects the perception of students on the role of being simulated patients, learners and instructors

supervising junior students.

Summary Of Work Methodology

This pilot study was conducted with the ten pioneers in the student simulation network at Almaarefa University. Student simulation is a voluntary student-led network (SSN) that

assists students from various phases (clinical and preclinical) in acquiring or excelling in clinical skills. The group was recruited by encouraging preclinical students to be simulated patients for a higher level. Two virtual meetings, each of a 2-hour duration, were conducted to teach the students their roles as simulators and revise the relevant symptoms with them. Besides that, these students were trained in clinical skills during their course Introduction to Clinical Medicine. At the end of the course, the students were enthusiastic about the idea of a (PAL-SBE). They created a student network whereby senior students would teach basic clinical skills to junior students. Then, the students completed a questionnaire reflecting their experience and views of the simulated peer learning experience.

Summary Of Results

Most students found the learning experience fun, interactive, and engaging, promoting collaboration and an opportunity for reflection and feedback. Perceived benefits included

enhanced confidence as an instructor, augmented clinical skills, good preparation for the clinical phase, and an innovative learning technique which enhanced the learning.

Challenges were related to time management (two different schedules) and fears of erroneous information delivery.

Discussion And Conclusion

The study highlights that SBE using PAL (PAL-SBE) is an enthusiastic, innovative and feasible approach that improves the clinical skills Teaching experience. It prepares the students to acquire instructor teaching skills and improve their clinical and communication skills. In future, structured clinical scenarios might be part of the simulated experience.

description: We demonstrate that the evolution of wall-like inhomogeneities in run-away potentials, characteristic of dynamical supersymmetry breaking and moduli stabilisation, is very similar to the evolution of domain wall networks associated with double well potentials. Instabilities that would lead to a rapid decay of domain walls can be significantly ameliorated by compensation effects between a non-degeneracy of the vacua and a biased initial distribution, which can be naturally expected in a wide class or particle physics models that lead to out-of-equilibrium phase transitions. Within this framework, it is possible to obtain domain walls that live long enough to be relevant for the cosmic power spectrum and galaxy clustering, while being compatible with the observed cosmic microwave background anisotropies.

description: We predict that superconductivity in thin films can be stabilized in high magnetic fields if the superconductor is driven out of equilibrium by a DC voltage bias. For realistic material parameters and temperatures, we show that superconductivity is restored in fields many times larger than the Chandrasekhar-Clogston limit. After motivating the effect analytically, we perform rigorous numerical calculations to corroborate the findings, and present concrete experimental signatures. On the technical side, we also introduce a new form for the nonequilibrium kinetic equations, which generalizes and simplifies previous formulations of the problem.

description: The irreversible currents and entropy production rate of a dilute colloidal suspension are calculated using the linear irreversible thermodynamics and the linear response theory. The \anomalous" or \hidden" entropy recently discussed in the context of the stochastic thermodynamics is fully accounted in these classic frameworks. We show that the two distinct formulations lead to identical results as long as the local equilibrium assumption or, equivalently the linear response theory, is valid.

Deposition, Oxidation, and Adhesion Mechanisms of Conformal Polydopamine Films

description: The oxidation of dopamine in aqueous solutions deposits thin conformal films on a wide variety of material surfaces. These films consist of a material known as polydopamine (PDA), and they exhibit chemical and structural similarities to melanin pigments and adhesive proteins secreted by mussels. The facile synthesis and versatile adhesion of PDA enable the functional modification of numerous material surfaces for applications in biomedical devices, energy storage, and water purification. This thesis details fundamental investigations into the deposition, oxidation, and adhesive mechanisms of PDA films. Depositing PDA films on substrates with different controlled chemistries revealed the importance of solution pH and initial deposition rates on the morphology of the films. The deposition of PDA molecules with increasing pH depends on two competing factors: increased generation rate of PDA molecules versus increased solubility due to catechol ionization. The areal density and coverage of three-dimensional PDA islands is influenced by the surface charge and hydrophobicity of the substrate in aqueous solutions. Spectroscopic and electrochemical characterization of PDA films revealed that redox-inactive metal cations can accelerate the oxidation of PDA. The generation of radicals of 5,6-dihydroxyindole were monitored in situ via ultraviolet-visible spectroscopy as a function of cation concentration and pH. The extent of oxidation was quantified by cyclic voltammetry. The resulting oxidation modifies the metal sorption properties of PDA by generating more carboxylic acid groups and enhancing the iron chelation of the films. The adhesive stability of PDA films was characterized by delamination kinetics of films on SiO2 and indium tin oxide (ITO). PDA film adhesion is a substrate, salt, and oxidation-dependent phenomenon. Long-term adhesive stability of PDA films can be promoted by use of higher dopamine concentrations during synthesis, incorporation of multivalent cations, and avoiding alkaline conditions and strongly oxidizing electrical bias. Elastic moduli of PDA films were quantified by compressive thin film wrinkling, and the measured value of 2.0 ± 0.9 GPA agrees with simulations of PDA based on an oligomeric aggregate model. This thesis helps develop a framework for understanding the synthesis, composition, microstructure, and stability of PDA films.

description: We present a general construction of two types of differential forms, based on any $(n{-}3)$-dimensional subspace in the kinematic space of $n$ massless particles. The first type is the so-called projective, scattering forms in kinematic space, while the second is defined in the moduli space of $n$-punctured Riemann spheres which we call worldsheet forms. We show that the pushforward of worldsheet forms, by summing over solutions of scattering equations, gives the corresponding scattering forms, which generalizes the results of [1711.09102]. The pullback of scattering forms to subspaces can have natural interpretations as amplitudes in terms of Bern-Carrasco-Johansson double-copy construction or Cachazo-He-Yuan formula. As an application of our formalism, we construct in this way a large class of $d\log$ scattering forms and worldsheet forms, which are in one-to-one correspondence with non-planar MHV leading singularities in ${\cal N}=4$ super-Yang-Mills. For every leading singularity function, we present a new determinant formula in moduli space, as well as a (combinatoric) polytope and associated scattering form in kinematic space. These include the so-called Cayley cases, where in each case the scattering form is the canonical forms of a convex polytope in the subspace, and scattering equations admit elegant rewritings as a map from the moduli space to the subspace.

description: We exploit the potential and power of the Becchi-Rouet-Stora-Tyutin (BRST) and anti-BRST invariant restrictions on the (anti-)chiral supervariables to derive the proper (anti-)BRST symmetries for the reparameterization invariant one (0+1)-dimensional (1D) toy models of the free relativistic particle as well as free spinning (i.e. supersymmetric) relativistic particle within the framework of (anti-)chiral supervariable approach to BRST formalism. Despite the (anti-)chiral super expansions of the (anti-)chiral supervariables, we observe that the (anti-)BRST charges, for the above toy models, turn out to be absolutely anticommuting in nature. This is one of the novel observations of our present endeavor. For this proof, we utilize the beauty and strength of Curci-Ferrari (CF) type restriction in the case of spinning relativistic particle but no such restriction is required in the case of the free scalar relativistic particle. We have also captured the nilpotency property of the conserved charges as well as the (anti-)BRST invariance of the appropriate Lagrangian(s) of our present toy models within the framework of (anti-)chiral supervariable approach.

description: Every year the DoD spends billions satisfying its large petroleum demand. This spending is highly sensitive to uncontrollable and poorly understood market forces. Additionally, while some stakeholders may not prioritize its monetary cost and risk, energy is fundamentally coupled to other critical factors. Energy, operational capability, and logistics are heavily intertwined and dependent on uncertain security environment and technology futures. These components and their relationships are less understood. Without better characterization, future capabilities may be significantly limited by present-day acquisition decisions. One attempt to demonstrate these costs and risks to decision makers has been through a metric known as the Fully Burdened Cost of Energy (FBCE). FBCE is defined as the commodity price for fuel plus many of these hidden costs. The metric encouraged a valuable conversation and is still required by law. However, most FBCE development stopped before the lessons from that conversation were incorporated. Current implementation is easy to employ but creates little value. Properly characterizing the costs and risks of energy and putting them in a useful tradespace requires a new framework. This research aims to highlight energy’s complex role in many aspects of military operations, the critical need to incorporate it in decisions, and a novel framework to do so. It is broken into five parts. The first describes the motivation behind FBCE, the limits of current implementation, and outlines a new framework that aids decisions. Respectively, the second, third, and fourth present a historic analysis of the connections between military capabilities and energy, analyze the recent evolution of this conversation within the DoD, and pull the historic analysis into a revised framework. The final part quantifies the potential impacts of deeply uncertain futures and technological development and introduces an expanded framework that brings capability, energy, and their uncertainty into the same tradespace. The work presented is intended to inform better policies and investment decisions for military acquisitions. The discussion highlights areas within the DoD’s understanding of energy that could improve or whose development has faltered. The new metric discussed allows the DoD to better manage and plan for long-term energy-related costs and risk.

description: Perturbative renormalization of a non-Abelian Chern-Simons gauge theory is examined. It is demonstrated by explicit calculation that, in the pure Chern-Simons theory, the beta-function for the coefficient of the Chern-Simons term vanishes to three loop order. Both dimensional regularization and regularization by introducing a conventional Yang-Mills component in the action are used. It is shown that dimensional regularization is not gauge invariant at two loops. A variant of this procedure, similar to regularization by dimensional reduction used in supersymmetric field theories is shown to obey the Slavnov-Taylor identity to two loops and gives no renormalization of the Chern-Simons term. Regularization with Yang-Mills term yields a finite integer-valued renormalization of the coefficient of the Chern-Simons term at one loop, and we conjecture no renormalization at higher order. We also examine the renormalization of Chern-Simons theory coupled to matter. We show that in the non-abelian case the Chern-Simons gauge field as well as the matter fields require infinite renormalization at two loops and therefore obtain nontrivial anomalous dimensions. We show that the beta function for the gauge coupling constant is zero to two-loop order, consistent with the topological quantization condition for this constant.

description: We explore the quantum transmission through open oval shaped quantum dots. The transmission spectra show periodic resonances and, depending on the geometry parameter, a strong suppression of the transmission for low energies. Applying a weak perpendicular magnetic field changes this situation drastically and introduces a large conductance. We identify the underlying mechanisms being partially due to the specific shape of the oval that causes a systematic decoupling of a substantial number of states from the leads. Importantly a pairwise destructive interference of the transmitting states is encountered thereby leading to the complete conductance suppression. Coupling properties and interferences can be tuned via a weak magnetic field. These properties are robust with respect to the presence of disorder in the quantum dot.

description: The contribution of Lorentz non-scalar operators to finite temperature correlation functions is discussed. Using the local duality approach for the one-pion matrix element of a product of two vector currents, the temperature dependence of the average gluonic stress tensor is estimated in the chiral limit to be $\langle{\bf E}^2 +{\bf B}^2\rangle_{T}=\frac{π^2}{10}bT^4$. At a normalization point $μ=0.5$ GeV we obtain $b\approx 1.1$. Together with the known temperature dependence of the Lorentz scalar gluon condensate we are able to infer $\langle{\bf E}^2\rangle_T$ and $\langle{\bf B}^2\rangle_T$ separately in the low-temperature hadronic phase.

Deliberative Perception

Year: 2017
Subjects: subject: 80101 Adaptive Agents and Intelligent Robotics
subject: FOS: Computer and information sciences

description: A recurrent and elementary robot perception task is to identify and localize objects of interest in the physical world. In many real-world situations such as in automated warehouses and assembly lines, this task entails localizing specific object instances with known 3D models. Most modern-day methods for the 3D multi-object localization task employ scene-to-model feature matching or regression/classification by learners trained on synthetic or real scenes. While these methods are typically fast in producing a result, they are often brittle, sensitive to occlusions, and depend on the right choice of features and/or training data. This thesis introduces and advocates a deliberative approach, where the multi-object localization task is framed as an optimization over the space of hypothesized scenes. We demonstrate that deliberative reasoning — such as understanding inter-object occlusions — is essential to robust perception, and that discriminative techniques can effectively guide such reasoning. The contributions of this thesis broadly fall under three parts: The first part, PErception via SeaRCH (PERCH) and its extension C-PERCH, formulates Deliberative Perception as an optimization over hypothesized scenes, and develops an efficient tree search algorithm for the same. The second part focuses on accelerating global search through statistical learners, in the form of search heuristics (Discriminatively-guided Deliberative Perception), and by modulating the search-space (RANSAC-Trees). The final part introduces general-purpose graph search algorithms that bridge statistical learning and search. Of these, the first is an anytime algorithm for leveraging edge validity priors to accelerate graph search, and the second, Improved Multi-Heuristic A*, permits the use of multiple, inadmissible heuristics that might arise from learning. Experimental validation on multiple robots and real-world datasets, one of which we introduce, indicates that we can leverage the complementary strengths of fast learningbased methods and deliberative classical search to handle both "hard" (severely occluded) and "easy" portions of a scene by automatically sliding the amount of deliberation required.

description: Designer optical control of interactions in ultracold atomic gases has wide application, from creating new quantum phases to modeling the physics of black holes. We demonstrate spatial control of interactions in a two-component cloud of $^6$Li fermions, using electromagnetically induced transparency (EIT) to create a "sandwich" of resonantly and weakly interacting regions. Interaction designs are imprinted on the trapped cloud by two laser beams and manipulated with just MHz changes in the frequency of one beam. We employ radio-frequency spectroscopy to measure the imprinted 1D spatial profiles of the local mean-field interactions and to demonstrate that the tuning range of the scattering length is the same for both optical and magnetic control. All of the data are in excellent agreement with our continuum-dressed state theoretical model of optical control, which includes both the spatial and momentum dependence of the interactions.

description: The effects of dilution disorder and random-displacement disorder are analyzed for dipolar-coupled magnetic moments confined in a plane, which were originally placed on the square lattice. In order to distinguish the different phases, new order parameters are derived and parallel tempering Monte Carlo simulations are performed for a truncated dipolar Hamiltonian to obtain the phase diagrams for both types of disorder. We find that both dilution disorder and random-displacement disorder give similar phase diagrams, namely disorder at small enough temperatures favors a so-called microvortex phase. This can be understood in terms of the flux closure present in dipolar-coupled systems.

Defect Formation Mechanisms in Powder-Bed Metal Additive Manufacturing

subject: FOS: Materials engineering

description: Metal Additive Manufacturing (AM) provides the means to fabricate complex metallic parts with reduced time to market and material waste and improved design freedom. Industries with strict materials qualifications such as aerospace, biomedical, and automotive are increasingly looking to AM to meet their production needs. However, significant materials-related challenges impede the widespread adoption of these technologies for critical components. In particular, fatigue resistance in as-built parts has proven to be inferior and unpredictable due to the large and variable presence of porosity. This presents a challenge for the qualification of any load bearing part without extensive post-processing, such as Hot Isostatic Pressing, and thorough inspection. Improved understanding of the underlying mechanisms behind defect formation will assist in designing process improvements to minimize or eliminate defects without relying entirely on postprocessing. In this work, the effects of powder, processing parameters, and post-processing on porosity formation in powder-bed metal AM processes are investigated using X-ray microtomography and a newly developed in-situ high speed radiography technique, Dynamic Xray Radiography. High resolution X-ray computed tomography is used to characterize defect morphology, size, and spatial distribution as a function of process and material inputs. Dynamic X-ray Radiography, which enables the in-situ observation of the laser-metal interactions at frame rates on the order of 100 kHz (and faster), is utilized to understand the dynamic behavior and transitions that occur in the vapor depression across process space. Experimental validation of previously held assumptions regarding defect formation as well as new insights into the influence of the vapor cavity on defect formation are presented.

All three hierarchies are shown to be equivalent and connection is established in the form of a symplectic gauge transformation. This construction results in a new representation of the W-infinity algebras in terms of 4 bosonic fields.

description: Deep understanding of urban mobility is of great significance for many real-world applications, such as urban traffic management and autonomous driving. This thesis develops deep learning methodologies to extract vehicle counts from streaming realtime video captured by multiple low resolution web cameras and construct maps of traffic density in a city environment; in particular, we focus on cameras installed in the Manhattan borough of NYC. The large-scale videos from these web cameras have low spatial and temporal resolution, high occlusion, large perspective, and variable environment conditions, making most existing methods to lose their efficacy. To overcome these challenges, the thesis develops several techniques: 1. a block-level regression model with a rank constraint to map the dense image feature into vehicle densities; 2. a deep multi-task learning framework based on fully convolutional neural networks to jointly learn vehicle density and vehicle count; 3. deep spatio-temporal networks for vehicle counting to incorporate temporal information of the traffic flow; and 4. multi-source domain adaptation mechanisms with adversarial learning to adapt the deep counting model to multiple cameras. To train and validate the proposed system, we have collected a largescale webcam traffic dataset CityCam that contains 60 million frames from 212 webcams installed in key intersections of NYC. Of there, 60; 000 frames have been annotated with rich information, leading to about 900; 000 annotated objects. To the best of our knowledge, it is the first and largest webcam traffic dataset with such large number of elaborate annotations. The proposed methods are integrated into the CityScapeEye system that has been extensively evaluated and compared to existing techniques on different counting tasks and datasets, with experimental results demonstrating the effectiveness and robustness of CityScapeEye.

description: In multichannel rings, evanescent modes will always co-exist with propagating modes. The evanescent modes can carry a very large diamagnetic persistent current that can oscillate with energy and are very sensitive to impurity scattering. This provides a natural explanation for the large diamagnetic persistent currents observed in experiments.

description: The vacuum Gowdy models provide much studied, non-trivial midi-superspace examples. Various technical issues within Loop Quantum Gravity can be studied in these models as well as one can hope to understand singularities and their resolution in the loop quantization. The first step in this program is to reformulate the model in real connection variables in a manner that is amenable to loop quantization. We begin with the unpolarized model and carry out a consistent reduction to the polarized case. Carrying out complete gauge fixing, the known solutions are recovered.

Zur Biologie myrmekophiler Kurzflügelkäfer der Gattung Pella (Coleoptera, Staphylinidae) in Baden-Württemberg unter besonderer Berücksichtigung von chemischer Verteidigung und Mimikry

description: Myrmekophilie, d. h. das Zusammenleben von Tieren mit Ameisen, ist ein seit langem bekanntes und faszinierendes Phänomen. Innerhalb der Käferfamilie der Kurzflügelkäfer (Staphyliniden) sind auffallend viele myrmekophile Arten zu finden und es wird angenommen, dass bestimmte Drüseninhaltsstoffe den Käfern das Zusammenleben mit den Ameisen ermöglichen. Im Rahmen der vorliegenden Arbeit wurde das Sekret der Tergaldrüse von fünf verschiedenen Pella-Arten (P. cognata, P. funesta, P. humeralis, P. laticollis und P. lugens) untersucht. Es enthält Chinone und neben anderen aliphatischen Bestandteilen meist große Mengen Undecan, das bei vielen Aleocharinen als Lösungsmittel der Chinone dient. Des Weiteren wurde bei drei Käfern (P. cognata, P. funesta und P. humeralis) 6-Methyl-5-hepten-2-on (Sulcaton) gefunden. Sowohl Undecan als auch Sulcaton sind als Alarmpheromone bei der glänzendschwarzen Holzameise Lasius fuliginosus, dem Hauptwirt dieser Käfer, bekannt. In Biotests zeigte sich, dass Sulcaton eine deterrente Wirkung auf Arbeiter von L. fuliginosus hat und daher eher zu den Alarmpheromonen zu zählen ist, die zu Flucht führen. Im Gegensatz dazu lösten die Substanzen Undecan und Chinon aggressives Verhalten bei L. fuliginosus aus. Undecan gehört damit zu den Alarmpheromonen, die eher Angriff auslösen. Mischt man Undecan und Chinon mit Sulcaton, wie es im Sekret der Käfer passiert, ist keine aggressionsauslösende Wirkung mehr festzustellen. Sulcaton ist offenbar in der Lage, die aggressivitätssteigernde Wirkung von Undecan und Chinon zu blockieren, und spielt so eine wichtige Rolle bei Interaktionen der Käfer mit ihrer Wirtsameise L. fuliginosus. Dies deutet auf chemische Mimikry der Alarmpheromone durch die Käfer hin. Es wird diskutiert, welche weiteren Mechanismen bei Interaktionen mit Ameisen insbesondere bei den Käfern, die nicht über Sulcaton verfügen, zum Tragen kommen und inwieweit die Unterschiede innerhalb der Käfer-Arten zu einer Besetzung unterschiedlicher ökologischer Nischen im Ameisennest führen. Abschließend wird anhand der Daten zur Chemie der Tergaldrüse ein hypothetischer Stammbaum für die Lomechusini erstellt, der auch mit morphologischen Unterschieden zur Deckung zu bringen ist.

Next-to-leading-logarithmic power corrections for $N$-jettiness subtraction in color-singlet production

description: We present a detailed derivation of the power corrections to the factorization theorem for the 0-jettiness event shape variable $\mathcal{T}$. Our calculation is performed directly in QCD without using the formalism of effective field theory. We analytically calculate the next-to-leading logarithmic power corrections for small $\mathcal{T}$ at next-to-leading order in the strong coupling constant, extending previous computations which obtained only the leading-logarithmic power corrections. We address a discrepancy in the literature between results for the leading-logarithmic power corrections to a particular definition of 0-jettiness. We present a numerical study of the power corrections in the context of their application to the $N$-jettiness subtraction method for higher-order calculations, using gluon-fusion Higgs production as an example. The inclusion of the next-to-leading-logarithmic power corrections further improves the numerical efficiency of the approach beyond the improvement obtained from the leading-logarithmic power corrections.

Decisions About Workplace Favor Requests

description: Today most organizations define job responsibilities less clearly than they did in the past. Additionally, increasing emphasis on personal initiative, empowerment, and self-management places a higher burden on workers to control their own activities. As such, decisions about whether to perform discretionary helping tasks, such as requested favors, is an important issue that faces all working professionals as they try to balance the many divergent demands on their time. This dissertation focuses on how individuals make decisions regarding whether to agree to favor requests, defined as “discretionary, prosocial behavior that is performed in response to a specific, explicit request from one person to another,” in the workplace. I show favors—because they are externally requested—are phenomenologically distinct from in-role behaviors and voluntary helping behaviors. I examine favor requests from the perspective of the performer to identify the motivations that influence responses to favor requests. I consider how favor decision-making—both the factors that people consider as well as the decision outcome— changes across individuals and situations. The dissertation contains three papers that contribute to this goal. Paper 1 defines favors and favor requests, distinguishes them from other workplace helping behaviors, and proposes a framework of the motivational processes of favor request decisions. Paper 2 provides an empirical test of the motivational framework proposed in Paper 1. Paper 3 examines the relationship among helping context, comparing favors versus volunteerism, gender, and guilt proneness. Overall, this stream of research is intended to develop an understanding of how people behave when confronted with favor requests.

description: Zwölfjährige Beobachtungen an Heuschrecken (Saltatoria) auf den Fildern/Württemberg zeigten den Zusammenhang zwischen ihrer Phänologie und dem von Jahr zu Jahr schwankenden Witterungsverlauf. Besonders auffällig waren dabei die Folgen des außergewöhnlich warmen Frühjahres 2007. Darüber hinaus wurden die Wärmesummen berechnet, die die Arten bis zum Erwachsensein benötigten. Diese Befunde stehen nur in lockerem Zusammenhang mit bestimmten Entwicklungsstadien von Blütenpflanzen. Schließlich ergaben sich Hinweise, dass die Heuschrecken aufgrund der Klimaerwärmung inzwischen ein bis zwei Wochen eher zu stridulieren beginnen als noch in der Mitte des 20. Jahrhunderts.

description: We consider the dynamics of gauge-Yukawa theories in the presence of a large number of matter constituents. We first review the current status for the renormalization group equations of gauge-fermion theories featuring also semi-simple groups. In this regime these theories develop an interacting ultraviolet fixed point that for the semi-simple case leads to a rich phase diagram. The latter contains a complete asymptotically safe fixed point repulsive in all couplings. We then add two gauged Weyl fermions belonging to arbitrary representations of the gauge group and a complex, gauged scalar to the original gauge-fermion theory allowing for new Yukawa interactions and quartic scalar self-coupling. Consequently, we determine the leading $1/N_f$ Yukawa and quartic beta functions. Our work elucidates, consolidates and extends results obtained earlier in the literature. We also acquire relevant knowledge about the dynamics of gauge-Yukawa theories beyond perturbation theory. Our findings are applicable to any extension of the standard model featuring a large number of fermions such as asymptotic safety.
