description: Magnesium (Mg) has the lowest density of all structural metals and has excellent potential for wide use in structural applications. While pure Mg has inferior mechanical properties; the addition of further elements at various concentrations has produced alloys with enhanced mechanical performance and corrosion resistance. An important consequence of adding such elements is that the saturated Mg matrix can locally decompose to form solute clusters and intermetallic particles, often referred to as precipitates. Controlling the shape, number density, volume fraction, and spatial distribution of solute clusters and precipitates significantly impacts the alloy's plastic response. Conversely, plastic deformation during thermomechanical processing can dramatically impact solute clustering and precipitation. In this paper, we first discuss how solute atoms, solute clusters, and precipitates can improve the mechanical properties of Mg alloys. We do so by primarily comparing three alloy systems: Mg-Al, Mg-Zn, and Mg-Y-based alloys. In the second part, we provide strategies for optimizing such microstructures by controlling nucleation and growth of solute clusters and precipitates during thermomechanical processing. In the third part, we briefly highlight how one can enable inverse design of Mg alloys by a more robust Integrated Computational Materials Design (ICMD) approach.
Fast quantum computation at arbitrarily low energy

description: One version of the energy-time uncertainty principle states that the minimum time $T_{\perp}$ for a quantum system to evolve from a given state to any orthogonal state is $h/(4 ΔE)$ where $ΔE$ is the energy uncertainty. A related bound called the Margolus-Levitin theorem states that $T_{\perp} \geq h/(2 E)$ where E is the expectation value of energy and the ground energy is taken to be zero. Many subsequent works have interpreted $T_{\perp}$ as defining a minimal time for an elementary computational operation and correspondingly a fundamental limit on clock speed determined by a system's energy. Here we present local time-independent Hamiltonians in which computational clock speed becomes arbitrarily large relative to E and $ΔE$ as the number of computational steps goes to infinity. We argue that energy considerations alone are not sufficient to obtain an upper bound on computational speed, and that additional physical assumptions such as limits to information density and information transmission speed are necessary to obtain such a bound.

On the Steiner property for planar minimizing clusters. The anisotropic case

description: In this paper we discuss the Steiner property for minimal clusters in the plane with an anisotropic double density. This means that we consider the classical isoperimetric problem for clusters, but volume and perimeter are defined by using two densities. In particular, the perimeter density may also depend on the direction of the normal vector. The classical "Steiner property" for the Euclidean case (which corresponds to both densities being equal to $1$) says that minimal clusters are made by finitely many ${\rm C}^{1,γ}$ arcs, meeting in finitely many "triple points". We can show that this property holds under very weak assumptions on the densities. In the parallel paper "On the Steiner property for planar minimizing clusters. The isotropic case" we consider the isotropic case, i.e., when the perimeter density does not depend on the direction, which makes most of the construction much simpler. In particular, in the present case the three arcs at triple points do not necessarily meet with three angles of $120^\circ$, which is instead what happens in the isotropic case.

description: A 44-year-old woman presented following minor trauma to her right knee. While dancing she externally rotated around a planted foot and felt sudden pain in her right knee. She presented with her knee locked in extension with a "dorsal fin" appearance of the soft tissues tented over the patella. This was diagnosed as a rare case of an intraarticular patella dislocation, which was rotated 90 degrees about the vertical axis. Closed reduction in the emergency room was unsuccessful but was achieved in theatre under general anaesthetic with muscle relaxation. Postreduction arthroscopy demonstrated that no osteochondral or soft tissue damage to the knee had been sustained. In patients presenting with a knee locked in extension with tenting of skin over the patella (the "dorsal fin" appearance), intra-articular patella dislocation should be suspected. Attempts to reduce vertical patella dislocations under sedation with excessive force or repeatedly without success should be avoided to prevent unnecessary damage to the patellofemoral joint. In this clinical situation we recommend closed reduction under general anaesthetic followed by immediate knee arthroscopy under the same anaesthetic to ensure that there is no chondral damage to the patella or femoral trochlea and to rule out an osteochondral fracture.

description: We consider the isoperimetric problem for clusters in the plane with a double density, that is, perimeter and volume depend on two weights. In this paper we consider the isotropic case, in the parallel paper "On the Steiner property for planar minimizing clusters. The anisotropic case", the anisotropic case is studied. Here we prove that, in a wide generality, minimal clusters enjoy the "Steiner property", which means that the boundaries are made by ${\rm C}^{1,γ}$ regular arcs, meeting in finitely many triple points with the $120^\circ$ property.

description: Process mining techniques focus on extracting insight in processes from event logs. Process mining has the potential to provide valuable insights in (un)healthy habits and to contribute to ambient assisted living solutions when applied on data from smart home environments. However, events recorded in smart home environments are on the level of sensor triggers, at which process discovery algorithms produce overgeneralizing process models that allow for too much behavior and that are difficult to interpret for human experts. We show that abstracting the events to a higher-level interpretation can enable discovery of more precise and more comprehensible models. We present a framework for the extraction of features that can be used for abstraction with supervised learning methods that is based on the XES IEEE standard for event logs. This framework can automatically abstract sensor-level events to their interpretation at the human activity level, after training it on training data for which both the sensor and human activity events are known. We demonstrate our abstraction framework on three real-life smart home event logs and show that the process models that can be discovered after abstraction are more precise indeed.

description: Le phénomène du décrochage scolaire et de la formation au secondaire II des 18-25 ans est un phénomène préoccupant, dont les effets se font ressentir au niveau national (10 %) et cantonal (15 %). Les centres de formation professionnelle spécialisés, dont le CFPS le Repuis sont des acteurs importants de l’accès aux diplômes professionnels pour nombre d’apprentis en situation de handicap ou ayant eu un cursus chaotique - mesures de transitions, périodes de latence et ruptures. Véritables maquisards de la formation, certains débouchent d’horizons divers et de parcours sinueux, souvent traumatisants et sont particulièrement sensibles aux facteurs de risque du décrochage. En brossant un tableau de la situation, du niveau national à celui des CFPS, nous découvrirons les particularités de cette jeunesse sensible et en quoi elle diffère ou ressemble aux apprentis du circuit traditionnel. À travers l’exemple concret du CFPS le Repuis, et en nous basant sur la littérature et les recherches internationales, cette étude invite à une réflexion sur les phénomènes de décrochage, ce qui peut les motiver et des mesures à mettre en place pour réduire les effets des facteurs de risque. À travers la construction d’un nouveau paradigme pédagogique, l’auteur vous invite à une réflexion sur l’instauration d’un environnement de formation approprié, propice aux échanges et à la conduite de formateurs issus de cultures diverses et sur les mécanismes de la prise en charge par des équipes pluridisciplinaires. D’une situation globale au cas particulier d’un centre de formation, le lecteur aura l’occasion de découvrir le monde encore méconnu de la formation professionnelle spécialisée et de ses enjeux, considérés sous l’angle des dynamiques sociales et des relations pédagogiques.

description: Le modèle à filières est ancré dans ce canton, seule la configuration des voies et le temps en tronc commun ont changé au fil du temps. Etant le séparatisme encore présent, ce travail tente de comprendre les motivations de l’Etat pour le maintien de ce système ainsi que les mécanismes sous-jacents du modèle segmenté. Une grande partie des recherches sont contraires à ce modèle de groupement, car séparer n’est pas synonyme de réussite, bien au contraire. Les recherches sont convergentes sur les conséquences néfastes pour les élèves plus faibles et sur les effets neutres pour les élèves forts. Ce modèle se révèle donc inégalitaire, inéquitable et injuste une fois que seulement les apprenants performants peuvent tirer profit. D’ailleurs, les cantons le plus inégalitaires de la Suisse utilisent le modèle à filières. Quels sont alors les enjeux politiques et sociaux non observables par la recherche pour qu’un système avec une telle défaillance soit maintenu ? Au travers d’un aperçu et des analyses sur des modèles plus intégratifs et individualisés existants ailleurs, ce mémoire bibliographique veillera à la recherche d’un système responsable qui intègre ses élèves, de manière équitable et égalitaire. Cela par le biais d’un projet pilote. Soit ; un modèle de gestion équitable qui prend en compte la diversité naturelle des élèves sans exclure les moins performants de l’accès au choix.

description: In the 1990s, after a series of experiments, the behavioral psychologist and economist Daniel Kahneman and his colleagues formulated the following Peak-End evaluation rule: "The remembered utility of pleasant or unpleasant episodes is accurately predicted by averaging the Peak (most intense value) of instant utility (or disutility) recorded during an episode and the instant utility recorded near the end of the experience", (D. Kahneman et al., 1997, QJE, p. 381). Hence, the simplest mathematical model for time evolution of the experienced utility function $u=u(t)$ can be given by the scalar differential equation $u'(t)=a u(t) + b \max \{u(s) : s\in [t-h,t]\}+f(t) \ (*),$ where $f$ represents exogenous stimuli, $h$ is the maximal duration of the experience, and $a, b \in \mathbb R$ are some averaging weights. In this work, we study equation $(*)$ and show that, for a range of parameters $a, b, h$ and a periodic sine-like term $f$, the dynamics of $(*)$ can be completely described in terms of an associated one-dimensional dynamical system generated by a piece-wise continuous map from a finite interval into itself. We illustrate our approach with two examples. In particular, we show that the hedonic utility $u(t)$ (`happiness') can exhibit chaotic behavior.

description: Cette recherche se base sur l’état actuel des connaissances en psychologie sur les travaux de groupes afin d’analyser trois binômes selon une méthodologie d’analyse de l’activité. Nous savons que des élèves de même niveau de compétences sont plus à même de collaborer et d’autant plus s’ils ont tous les deux un niveau faible. Les élèves peuvent poursuivre différents types de but lorsqu’ils collaborent. Tout d’abord le but de maîtrise qui correspond à une volonté intrinsèque de comprendre et d’apprendre. Ensuite les buts de performance approche qui est une compétition dont le but est de montrer sa supériorité et enfin le but de performance évitement qui correspond à la volonté de ne pas paraître faible. En ce qui concerne les travaux collaboratifs de bonne qualité, certaines règles ont été édictées comme la nécessité de créer une tâche mobilisant les deux élèves, des groupes de petite taille, une interdépendance positive… Les élèves réalisent une tâche d’étude de texte et doivent répondre ensemble à un questionnaire. Par la suite ils devront commenter leur travail sur la base des documents vidéo recueillie durant l’activité. Ces données sont ensuite transcrites afin de permettre une analyse fine. Au fil de l’analyse, nous constatons que les éléments théoriques concernant la composition des groupes et les aptitudes des élèves sont observables en tout cas partiellement dans notre travail. Toutefois notre analyse permet de mettre en évidence avec une grande précision les étapes par lesquelles les élèves passent afin de mener à bien leur tâche et cela nous permet de montrer que les élèves sont relativement peu souvent en but de maîtrise. Quelques pistes d’explication sont à chercher du côté des contextes de l’activité, dans la nature des questions, dans la culture, le genre et l’expérience des élèves. Finalement, ce travail met en évidence les défis à relever afin de mettre en place des situations de collaboration en classe et donne des pistes afin de favoriser la collaboration entre élèves, notamment en identifiant une série de comportements informant sur la qualité de la collaboration des élèves.

description: Self-driving cars face complex driving situations with a large amount of agents when moving in crowded cities. However, some of the agents are actually not influencing the behavior of the self-driving car. Filtering out unimportant agents would inherently simplify the behavior or motion planning task for the system. The planning system can then focus on fewer agents to find optimal behavior solutions for the ego~agent. This is helpful especially in terms of computational efficiency. In this paper, therefore, the research topic of importance filtering with driving risk models is introduced. We give an overview of state-of-the-art risk models and present newly adapted risk models for filtering. Their capability to filter out surrounding unimportant agents is compared in a large-scale experiment. As it turns out, the novel trajectory distance balances performance, robustness and efficiency well. Based on the results, we can further derive a novel filter architecture with multiple filter steps, for which risk models are recommended for each step, to further improve the robustness. We are confident that this will enable current behavior planning systems to better solve complex situations in everyday driving.

As a by-product, we obtain new globalization results in cases never considered before, such as partial corepresentations of Hopf algebras. Moreover, we show that for partial representations of groups and Hopf algebras, our globalization coincides with those described earlier in literature. Finally, we introduce Hopf partial comodules over a bialgebra as geometric partial comodules in the monoidal category of (global) modules. By applying our globalization theorem we obtain an analogue of the fundamental theorem for Hopf modules in this partial setting.

description: We analyze synthetic neutral hydrogen (HI) absorption and emission spectral lines from a high- resolution, three-dimensional hydrodynamical simulation to quantify how well observational methods recover the physical properties of interstellar gas. We present a new method for uniformly decomposing HI spectral lines and estimating the properties of associated gas using the Autonomous Gaussian Decomposition (AGD) algorithm. We find that Hi spectral lines recover physical structures in the simulation with excellent completeness at high Galactic latitude, and this completeness declines with decreasing latitude due to strong velocity-blending of spectral lines. The temperature and column density inferred from our decomposition and radiative transfer method agree with the simulated values within a factor of < 2 for the majority of gas structures. We next compare synthetic spectra with observations from the 21-SPONGE survey at the Karl G. Jansky Very Large Array using AGD. We find more components per line of sight in 21-SPONGE than in synthetic spectra, which reflects insufficient simulated gas scale heights and the limitations of local box simulations. In addition, we find a significant population of low-optical depth, broad absorption components in the synthetic data which are not seen in 21-SPONGE. This population is not obvious in integrated or per-channel diagnostics, and reflects the benefit of studying velocity-resolved components. The discrepant components correspond to the highest spin temperatures (1000 < Ts < 4000 K), which are not seen in 21-SPONGE despite sufficient observational sensitivity. We demonstrate that our analysis method is a powerful tool for diagnosing neutral ISM conditions, and future work is needed to improve observational statistics and implementation of simulated physics.

description: L’aménagement journalier du temps scolaire a une grande influence sur l’apprentissage des élèves. Plusieurs facteurs pèsent sur les systèmes éducatifs et compliquent la mise en place d’un apprentissage optimal, parce qu’il faudrait tenir compte premièrement de la chronopsychologie des enfants, et deuxièmement des facteurs externes (économiques, sociétaux, politiques et religieux). Par contre, les enseignants ont des marges de manoeuvre dans la planification et la gestion des leçons, et peuvent essayer de surmonter les variations d’attention et de performance des enfants. Les enseignants plus confrontés à ces variations sont ceux des premières années de l’école primaire, car plus les élèves sont jeunes, plus ils sont sujets aux variations. Aucune étude n’a été menée sur ce thème dans le canton suisse du Tessin. Nous nous sommes donc intéressés à la connaissance que les enseignants tessinois de 3P et 4P ont de la variation d’attention et de performance des enfants, et avons cherché à savoir s’ils la prennent en considération pendant la préparation des leçons. Notre démarche passe par la réalisation d’un questionnaire soumis à près d’une trentaine d’enseignants. Les données quantitatives et qualitatives récoltées nous ont permis de constater qu’ils sont informés de la variation d’attention et qu’ils la prennent en considération, mais que leurs connaissances sont opposées aux résultats des études scientifiques sur la chronopsychologie. Les résultats obtenus dans ce travail mettent aussi en évidence le type d’activités proposées par les enseignants et les stratégies mises en place pour affronter la variation journalière de l’attention et de la performance.

description: We conducted a human subject study of named entity recognition on a noisy corpus of conversational music recommendation queries, with many irregular and novel named entities. We evaluated the human NER linguistic behaviour in these challenging conditions and compared it with the most common NER systems nowadays, fine-tuned transformers. Our goal was to learn about the task to guide the design of better evaluation methods and NER algorithms. The results showed that NER in our context was quite hard for both human and algorithms under a strict evaluation schema; humans had higher precision, while the model higher recall because of entity exposure especially during pre-training; and entity types had different error patterns (e.g. frequent typing errors for artists). The released corpus goes beyond predefined frames of interaction and can support future work in conversational music recommendation.

description: In this survey we report some recent results in the mathematical modeling of epidemic phenomena through the use of kinetic equations. We initially consider models of interaction between agents in which social characteristics play a key role in the spread of an epidemic, such as the age of individuals, the number of social contacts, and their economic wealth. Subsequently, for such models, we discuss the possibility of containing the epidemic through an appropriate optimal control formulation based on the policy maker's perception of the progress of the epidemic. The role of uncertainty in the data is also discussed and addressed. Finally, the kinetic modeling is extended to spatially dependent settings using multiscale transport models that can characterize the impact of movement dynamics on epidemic advancement on both one-dimensional networks and realistic two-dimensional geographic settings.

description: Chiral magnets are an emerging class of topological matter harbouring localized and topologically protected vortex-like magnetic textures called skyrmions, which are currently under intense scrutiny as a new entity for information storage and processing. Here, on the level of micromagnetics we rigorously show that chiral magnets cannot only host skyrmions but also antiskyrmions as least-energy configurations over all non-trivial homotopy classes. We derive practical criteria for their occurrence and coexistence with skyrmions that can be fulfilled by (110)-oriented interfaces in dependence on the electronic structure. Relating the electronic structure to an atomistic spin-lattice model by means of density-functional calculations and minimizing the energy on a mesoscopic scale applying spin-relaxation methods, we propose a double layer of Fe grown on a W(110) substrate as a practical example. We conjecture that ultrathin magnetic films grown on semiconductor or heavy metal substrates with $C_{2v}$ symmetry are prototype classes of materials hosting magnetic antiskyrmions.

description: Essential to the study of heavy ion collisions are probes that are produced in the collision itself. Photons are a very useful probe of the collisions, since they escape the fireball virtually unmodified and carry with them information about the environment in which it was produced. Recent interest in low momentum direct photons has increased, due to the onset of the “thermal photon puzzle” and the apparent inability for typical models to explain both a large direct photon yield excess and large azimuthal production asymmetry (v2) at low momentum measured by PHENIX.

description: Objective: The main goal of the athletes who undergo anterior cruciate ligament reconstruction (ACLR) surgery is a successful return-to-sport. At this stage, identifying muscular deficits becomes important. Hence, in this study, three discriminative features based on surface electromyographic signals (sEMG) acquired in a dynamic protocol are introduced to assess the damping ability and interpret activation patterns in lower-limb muscles of ACLR athletes. Methods: The features include the median frequency of the power spectrum density (PSD), the relative percentage of the equivalent damping or equivalent stiffness derived from the median frequency, and the energy of the signals in the time-frequency plane of the pseudo-Wigner-Ville distribution (PWVD). To evaluate the features, 11 healthy and 11 ACLR athletes (6 months post-reconstruction surgery) were recruited to acquire the sEMG signals from the medial and the lateral parts of the hamstrings, quadriceps, and gastrocnemius muscles in pre- and post-fatigue single-leg landings. Results: A significant damping deficiency is observed in the hamstring muscles of ACLR athletes by evaluating the proposed features. This deficiency indicates that more attention should be paid to this muscle of ACLR athletes in pre-return-to-sport rehabilitations. Conclusion: The quality of electromyography-based pre-return-to-sport assessments on ACLR subjects depends on the sEMG acquisition protocol, as well as the type and nature of the extracted features. Hence, combinatorial application of both energy-based features (derived from the PWVD) and power-based features (derived from the PSD) could facilitate the assessment process by providing additional biomechanical information regarding the behavior of the muscles surrounding the knee.

This study evaluated the efficacy of laser surgery (CO2 and diode) in the excision of vulvar cysts, regarding two clinical cases of women, aged 37 and 39 years, highlighting the rarity and relevance of this condition in gynecological practice. CO2 and diode lasers were used for excision of the cysts, evaluating their efficacy and postoperative evolution. The results showed complete excision of the cysts, with no intraoperative complications. Postoperative evolution was satisfactory, with one case of mild infection adequately managed. The histopathological study confirmed the benign nature of the masses. Patients expressed satisfaction with the results. These findings support the efficacy and safety of laser surgery for vulvar cysts, underlining the importance of second intention closure in the postoperative course. In conclusion, laser surgery is an effective and safe option for vulvar cysts, with significant implications for clinical practice and patients' quality of life. The case study not only contributes to medical knowledge by validating the efficacy and safety of laser surgery for vulvar cysts, but also underscores the importance of considerations such as closure by secondary intention and patient satisfaction in the treatment process.

title: CuO Nanoparticles Solubility as Influenced by Soil Pore Water, Native Microorganisms, and Wheat Rhizosphere Chemistry in a Sand Matrix
Creators: name: Sparks, Dakota
Publisher: name: Utah State University
Year: 2022

description: Nanoparticles (NPs) are particles less than 100 nm (~4 millionths of an inch) in a direction. NPs, due to their small size, are used in a variety of products, such as silver (Ag) NPs as an antimicrobial in clothes. Copper Oxide (CuO) NPs are used in electronics as semiconductors and other fields as antimicrobials and purposefully or accidentally end up in the environment. Copper (Cu) is a necessary nutrient for plants, but at higher amounts is toxic to plants and beneficial soil microbes.
In order to understand how the CuO NPs interacts with plants, wheat seedlings were grown in sand for 10 days. The sand was watered with water extracted from three soils differing in properties relevant to CuO NP dissolution. The SPEs were either sterilized, to provide information on the wheat releases (exudates) into the sand as it grows, or contained native microbes, so that the wheat with microbes could mimic a natural environment. The sand was amended with a low and high dose of CuO NPs to provide two different environments for the wheat to react in.
The higher dose of CuO caused the wheat to release greater amounts of exudates. In the presence of microbes, the amounts of exudates drastically decreased, yet the amount of Cu complexed did not drastically change; instead, soil components such as fulvic acid complexed with the Cu. The amount of Cu associated with the roots depended on the amount of NPs added and resulted in root mass with wheat that had less organic matter in the SPEs, but the wheat, regardless of the conditions it was grown in, was able to regulate the amount of Cu taken into the shoots.

description: We recast the action of pure gravity into a form that is invariant under a twofold Lorentz symmetry. To derive this representation, we construct a general parameterization of all theories equivalent to the Einstein-Hilbert action up to a local field redefinition and gauge fixing. We then exploit this freedom to eliminate all interactions except those exhibiting two sets of independently contracted Lorentz indices. The resulting action is local, remarkably simple, and naturally expressed in a field basis analogous to the exponential parameterization of the nonlinear sigma model. The space of twofold Lorentz invariant field redefinitions then generates an infinite class of equivalent representations. By construction, all off-shell Feynman diagrams are twofold Lorentz invariant while all on-shell tree amplitudes are automatically twofold gauge invariant. We extend our results to curved spacetime and calculate the analogue of the Einstein equations. While these twofold invariances are hidden in the canonical approach of graviton perturbation theory, they are naturally expected given the double copy relations for scattering amplitudes in gauge theory and gravity.

Compressible turbulence in the interstellar medium: New insights from a high-resolution supersonic turbulence simulation

description: The role of supersonic turbulence in structuring the interstellar medium (ISM) remains an unsettled question. Here, this problem is investigated using a newexact law of compressible isothermal hydrodynamic turbulence, which involves two-point correlations in physical space. The new law is shown to have a compact expression that contains a single flux term reminiscent of the incompressible case and a source term with a simple expression whose sign is given by the divergence of the velocity. The law is then used to investigate the properties of such a turbulence at integral Mach number $4$ produced by a massive numerical simulation with a grid resolution of $10,048^3$ points. The flux (resp. source) term was found to have positive (resp. negative) contribution to the total energy cascade rate, which is interpreted as a direct cascade amplified by compression, while their sum is constant in the inertial range. Using a local (in space) analysis it is shown that the source is mainly driven by filamentary structures in which the flux is negligible. Taking positive defined correlations reveals the existence of different turbulent regimes separated by the sonic scale, which determines the scale over which the non-negligible source modifies the scaling of the flux. Our study provides new insight into the dynamics and structures of supersonic interstellar turbulence.

Device-Independent Oblivious Transfer from the Bounded-Quantum-Storage-Model and Computational Assumptions

description: We present a device-independent protocol for oblivious transfer (DIOT) and analyze its security under the assumption that the receiver's quantum storage is bounded during protocol execution and that the device behaves independently and identically in each round. We additionally require that, for each device component, the input corresponding to the choice of measurement basis, and the resulting output, is communicated only with the party holding that component. Our protocol is everlastingly secure and, compared to previous DIOT protocols, it is less strict about the non-communication assumptions that are typical from protocols that use Bell inequality violations; instead, the device-independence comes from a protocol for self-testing of a single (quantum) device which makes use of a post-quantum computational assumption.

description: Such natural events as earthquakes exhibit complexity and have high uncertainty and non-linear characteristics as well. It has prompted many scientists from diverse domains to be interested in the problem and to perform its thorough exploration. In the last 20 years, scholars have brought methods of network science into earthquake research. In this work, we prepared a network model and analyzed the seismic network characteristics during the 2008 Wenchuan earthquake in Sichuan, China. The results of the study demonstrate that the seismic data relations in the Sichuan region are in line with the small-world and scale-free network properties.

description: Weyl conformal symmetry can solve the problem the spacetime singularities present in Einstein's gravity. In a recent paper, two of us have found a singularity-free rotating black hole solution in conformal gravity. In addition to the mass $M$ and the spin angular momentum $J$ of the black hole, the new solution has a new parameter, $L$, which here we consider to be proportional to the black hole mass. Since the solution is conformally equivalent to the Kerr metric, photon trajectories are unchanged, while the structure of an accretion disk around a black hole is affected by the value of the parameter $L$. In this paper, we show that X-ray data of astrophysical black holes require $L/M < 1.2$.
