description: Contexte : Les soins palliatifs ont émergé en réponse au vieillissement démographique. Ils sont donc peu développés au niveau de la pédiatrie, ce qui entrave la continuité des soins pour cette population. Or, l’accès à ces soins pour les adolescents doit être spécifique à leurs besoins. Objectifs : Identifier quels sont les besoins des adolescents en fin de vie. Stratégies de recherche : Deux bases de données ont été utilisées : CINAHL et MedLine, par le biais de mots-clés, de descripteurs et de Mesh. Parmi tous les articles identifiés, six articles répondant à l’objectif ont été inclus selon des critères d’inclusion et d’exclusion. Synthèse des données : Les articles ont été synthétisés sous forme de tableaux et leurs résultats ont été analysés par le biais du modèle théorique de Nola Pender. Résultats : Après l’analyse des six articles, différents facteurs ont été identifiés comme ayant une influence sur les besoins et sur l’engagement dans un comportement de promotion de santé. Ces facteurs sont de type : individuels, interpersonnels, situationnels et liés aux comportements spécifiques, à la cognition et aux sentiments. Discussion : Les résultats suggèrent que les discussions de fin de vie devraient inclure l’adolescent et avoir lieu avant la phase terminale. Cette intervention augmente la congruence entre les adolescents et leur représentant et permet la promotion du respect des souhaits de l’adolescent. Ceci permettrait de diminuer la souffrance et d’augmenter la qualité de vie. Certains auteurs recommandent qu’il serait nécessaire de développer des structures hospitalières spécialisées pour les adolescents.

description: Problématique : La sclérose latérale amyotrophique (SLA) est une maladie neurodégénérative entraînant de la dysphagie et des symptômes interreliés, qui altèrent la qualité de vie du patient. Objectif : Définir le rôle infirmier dans la prise en charge de la dysphagie afin de maintenir la qualité de vie des patients atteints de SLA. Méthode : Deux bases de données ont été utilisées pour la recherche d’articles scientifiques, CINAHL et Pubmed. Sept articles ont été retenus par une lecture critique à l’aide des grilles de Fortin (2010) et des critères d’inclusion suivants : études réalisées entre 2005-2015, adultes de 45-64 ans atteints de SLA, recherches européennes et canadiennes. Les résultats sont synthétisés à l’aide de tableaux et discutés avec la théorie de la gestion des symptômes (Dodd et al., 2001). Résultats : La synthèse des résultats a permis d’identifier trois thèmes principaux : la qualité de vie, les stratégies d’adaptation et les soins pluridisciplinaires. Discussion : L’interdisciplinarité favorise l’expertise et une prise en charge globale. L’individualisation, l’anticipation et la continuité des soins sont des stratégies d’adaptation. L’addition des stratégies à la prise en charge pluridisciplinaire permet de dispenser des soins de qualité et de renforcer la qualité de vie des patients. Conclusion : Ce travail offre des suggestions pour la pratique et des propositions permettant de décrire le rôle infirmier dans la prise en charge de la dysphagie. La persévérance des recherches scientifiques sur la SLA est toutefois indispensable.

description: We present a scheme for engineering the extended two-component Bose-Hubbard model using polariton condensate supported by optical microcavity. Compared to the usual two-component Bose-Hubbard model with only Kerr nonlinearity, our model includes a nonlinear tunneling term which depends on the number difference of the particle in the two modes. In the mean field treatment, this model is an analog to a nonrigid pendulum with a variable pendulum length whose sign can be also changed. We study the dynamic and ground state properties of this model and show that there exists a first-order phase transition as the strength of the nonlinear tunneling rate is varied. Furthermore, we propose a scheme to obtain the polariton condensate wave function.

description: "Quaternionic" vector bundles are the objects which describe the topological phases of quantum systems subjected to an odd time-reversal symmetry (class AII). In this work we prove that the FKMM invariant provides the correct fundamental characteristic class for the classification of "Quaternionic" vector bundles in dimension less than, or equal to three (low dimension). The new insight is provided by the interpretation of the FKMM invariant from the viewpoint of the Bredon equivariant cohomology. This fact, along with basic results in equivariant homotopy theory, allows us to achieve the expected result.

description: Problématique : La douleur iatrogène ressentie de façon récurrente par les enfants peut avoir des conséquences sur la mémorisation. La manière dont ils se souviennent des procédures médicales douloureuses affecte leur expérience de douleur et de détresse durant les procédures futures. Une prise en charge globale de la douleur, intégrant les aspects physiques, psycho spirituels, socio-culturels, environnementaux est nécessaire au vu de sa nature multidimensionnelle. But : L’objectif de ce travail vise à évaluer l’efficacité de la distraction dans la diminution de douleur lors d’une prise de sang ou la pose d’un cathéter veineux périphérique chez les enfants de deux à douze ans. Méthodologie : La recherche d’articles scientifiques a été effectuée sur les bases de données CINAHL et PubMed. Les critères d’inclusion et d’exclusion ont permis d’affiner les résultats et ainsi sélectionner sept études quantitatives. Résultats : Les études analysées ont démontré l’efficacité de plusieurs méthodes de distraction dans la diminution de la douleur procédurale, de la détresse, de la peur et de l’anxiété. Un seul article utilise la distraction couplée au positionnement parental et prouve l'effet positif de cette intervention multimodale. Discussion : Les concepts émergeant des résultats comprennent la détresse, le positionnement parental et les outils d’évaluation ; les infirmières doivent en tenir compte lors des interventions. Les méthodes de distraction se caractérisent par leur facilité et leur rapidité d’exécution ainsi que par leur faible coût.
Accelerating self-consistent field iterations in Kohn-Sham density functional theory using a low rank approximation of the dielectric matrix

description: We present an efficient preconditioning technique for accelerating the fixed point iteration in real-space Kohn-Sham density functional theory (DFT) calculations. The preconditioner uses a low rank approximation of the dielectric matrix (LRDM) based on Gâteaux derivatives of the residual of fixed point iteration along appropriately chosen direction functions. We develop a computationally efficient method to evaluate these Gâteaux derivatives in conjunction with the Chebyshev filtered subspace iteration procedure, an approach widely used in large-scale Kohn-Sham DFT calculations. Further, we propose a variant of LRDM preconditioner based on adaptive accumulation of low-rank approximations from previous SCF iterations, and also extend the LRDM preconditioner to spin-polarized Kohn-Sham DFT calculations. We demonstrate the robustness and efficiency of the LRDM preconditioner against other widely used preconditioners on a range of benchmark systems with sizes ranging from $\sim$ 100-1100 atoms ($\sim$ 500--20,000 electrons). The benchmark systems include various combinations of metal-insulating-semiconducting heterogeneous material systems, nanoparticles with localized $d$ orbitals near the Fermi energy, nanofilm with metal dopants, and magnetic systems. In all benchmark systems, the LRDM preconditioner converges robustly within 20--30 iterations. In contrast, other widely used preconditioners show slow convergence in many cases, as well as divergence of the fixed point iteration in some cases. Finally, we demonstrate the computational efficiency afforded by the LRDM method, with up to 3.4$\times$ reduction in computational cost for the total ground-state calculation compared to other preconditioners.

description: Agnotology is the study of culturally and socially constructed ignorance. This paper seeks to marry the emerging field of agnotology with the institutions and mechanisms of politics by providing analyses of political ignorance focusing on a theoretical framework built on agnotological practices. As the political landscape becomes increasingly more beleaguered with misinformation, an understanding on how gaps in political knowledge are created, incentivized, and maintained can provide insights on how to move remedial ideas of misinformation from theory to praxis. The recognition of ignorance as a tool of power, particularly in areas like business, governance, and politics, has raised concerns about its impact on democracy. Agnotology plays a significant role in shaping political culture and has profound effects on public opinion, discourse, and democratic engagement, which are threatened by information manipulation and fake news. Understanding the historical and contemporary instances of ignorance production can provide insights into diagnosing, predicting, and addressing the epistemic challenges faced by modern democracy. Case studies involving political philosophy, public health, sociology, trans health, pharmaceutical operations, business, the presidency, and nuclear epistemology are used to inform the analysis.

description: We analyze the general black hole solutions to the four dimensional STU model recently constructed by Chow and Compere. We define a dilute gas limit where the black holes can be interpreted as excited states of an extremal ground state. In this limit we express the black hole entropy and the excitation energy in terms of physical quantities with no need for parametric charges. We discuss a dual microscopic CFT description that incorporates all electric and magnetic charges. This description is recovered geometrically by identification of a near horizon BTZ region. We construct the subtracted geometry with no restrictions on charges by analyzing the scalar wave equation in the full geometry. We determine the matter sources that support the subtracted geometry by studying a scaling limit and show that the general geometry permits a dilute gas description with parameters that we specify.

description: We propose a class of randomized quantum Krylov diagonalization (rQKD) algorithms capable of solving the eigenstate estimation problem with modest quantum resource requirements. Compared to previous real-time evolution quantum Krylov subspace methods, our approach expresses the time evolution operator, $e^{-i\hat{H} τ}$, as a linear combination of unitaries and subsequently uses a stochastic sampling procedure to reduce circuit depth requirements. While our methodology applies to any Hamiltonian with fast-forwardable subcomponents, we focus on its application to the explicitly double-factorized electronic-structure Hamiltonian. To demonstrate the potential of the proposed rQKD algorithm, we provide numerical benchmarks for a variety of molecular systems with circuit-based statevector simulators, achieving ground state energy errors of less than 1~kcal~mol$^{-1}$ with circuit depths orders of magnitude shallower than those required for low-rank deterministic Trotter-Suzuki decompositions.

description: Introduction : selon la base de données internationale de l’Office of U.S. Foreign Disaster Assistance et le Centre for Research on the Epidemiology of Disasters, plus de 220 millions de personnes sont affectées par des catastrophes naturelles par année et plus de 92 000 y trouvent la mort. Ces personnes sont une population à risque et entre 10 à 20% des survivants ont des symptômes de stress posttraumatique. Ces personnes vivent une transition. Objectif : répondre par une revue non-systématique d’articles à la question de recherche : Peut-on diminuer la symptomatologie d’un PTSD de manière efficiente en mettant en place des interventions infirmières spécifiques selon la théorie de la transition dans le but d’accélérer le processus de conscientisation de l’événement traumatique, permettant à la victime de catastrophe naturelle de retrouver un équilibre psychologique et des repères affectifs et sociaux? Méthode : recherche d’articles, par mots-clés et descripteurs, dans deux bases de données (PubMed et PsycINFO). Six études ont été retenues. Résultats : la synthèse des résultats met en évidence l’efficacité de la conscientisation de l’événement vécu pour le traitement du PTSD, ceci par le biais de thérapies comme la psychoéducation et le contrôle des sens. Un autre aspect qui a été relevé est la présence de facteurs protecteurs et facteurs aggravants ainsi que le rôle important de la prévention. Discussion : une diminution rapide des symptômes d’un PTSD est observable lorsque ces derniers sont traités de manière adéquate et ciblée.

description: A common assumption in belief revision is that the reliability of the information sources is either given, derived from temporal information, or the same for all. This article does not describe a new semantics for integration but the problem of obtaining the reliability of the sources given the result of a previous merging. As an example, the relative reliability of two sensors can be assessed given some certain observation, and allows for subsequent mergings of data coming from them.

description: We consider the topological and geometric reconstruction of a geodesic subspace of $\mathbb{R}^N$ both from the Čech and Vietoris-Rips filtrations on a finite, Hausdorff-close, Euclidean sample. Our reconstruction technique leverages the intrinsic length metric induced by the geodesics on the subspace. We consider the distortion and convexity radius as our sampling parameters for a successful reconstruction. For a geodesic subspace with finite distortion and positive convexity radius, we guarantee a correct computation of its homotopy and homology groups from the sample. For geodesic subspaces of $\mathbb{R}^2$, we also devise an algorithm to output a homotopy equivalent geometric complex that has a very small Hausdorff distance to the unknown shape of interest.

We present a simple numerical procedure for the solution of the equation of motion of the system to be implemented by students and teachers. Interesting qualitative concepts as well as quantitative results for the focused problem are presented. The topic has pedagogical value both from theoretical and experimental point of view. However, this article considers only theoretical aspects of the problem. The work is addressed to basic physics courses at undergraduate level.

description: We investigate the nature of excitons bound to I1 basal-plane stacking faults [(I1;X)] in GaN nanowire ensembles by continuous-wave and time-resolved photoluminescence spectroscopy. Based on the linear increase of the radiative lifetime of these excitons with temperature, they are demonstrated to exhibit a two-dimensional density of states, i. e., a basal-plane stacking fault acts as a quantum well. From the slope of the linear increase, we determine the oscillator strength of the (I1;X) and show that the value obtained reflects the presence of large internal electrostatic fields across the stacking fault. While the recombination of donor-bound and free excitons in the GaN nanowire ensemble is dominated by nonradiative phenonema already at 10 K, we observe that the (I1;X) recombines purely radiatively up to 60 K. This finding provides important insight into the nonradiative recombination processes in GaN nanowires. First, the radiative lifetime of about 6 ns measured at 60 K sets an upper limit for the surface recombination velocity of 450 cm/s considering the nanowires mean diameter of 105 nm. Second, the density of nonradiative centers responsible for the fast decay of donor-bound and free excitons cannot be higher than 2x10^16 cm^-3. As a consequence, the nonradiative decay of donor-bound excitons in these GaN nanowire ensembles has to occur indirectly via the free exciton state.

description: Monocular depth estimation is the task of obtaining a measure of distance for each pixel using a single image. It is an important problem in computer vision and is usually solved using neural networks. Though recent works in this area have shown significant improvement in accuracy, the state-of-the-art methods tend to require massive amounts of memory and time to process an image. The main purpose of this work is to improve the performance of the latest solutions with no decrease in accuracy. To this end, we introduce the Double Refinement Network architecture. The proposed method achieves state-of-the-art results on the standard benchmark RGB-D dataset NYU Depth v2, while its frames per second rate is significantly higher (up to 18 times speedup per image at batch size 1) and the RAM usage per image is lower.

description: Inclusive and differential measurements of the top-antitop ($t\bar{t}$) charge asymmetry $A_\text{C}^{t\bar{t}}$ and the leptonic asymmetry $A_\text{C}^{\ell\bar{\ell}}$ are presented in proton-proton collisions at $\sqrt{s} = 13$ TeV recorded by the ATLAS experiment at the CERN Large Hadron Collider. The measurement uses the complete Run 2 dataset, corresponding to an integrated luminosity of 139 fb$^{-1}$, combines data in the single-lepton and dilepton channels, and employs reconstruction techniques adapted to both the resolved and boosted topologies. A Bayesian unfolding procedure is performed to correct for detector resolution and acceptance effects. The combined inclusive $t\bar{t}$ charge asymmetry is measured to be $A_\text{C}^{t\bar{t}} = 0.0068 \pm 0.0015$, which differs from zero by 4.7 standard deviations. Differential measurements are performed as a function of the invariant mass, transverse momentum and longitudinal boost of the $t\bar{t}$ system. Both the inclusive and differential measurements are found to be compatible with the Standard Model predictions, at next-to-next-to-leading order in quantum chromodynamics perturbation theory with next-to-leading-order electroweak corrections. The measurements are interpreted in the framework of the Standard Model effective field theory, placing competitive bounds on several Wilson coefficients.

description: We show that if $K$ is a fibered ribbon knot in $S^3=\partial B^4$ bounding a ribbon disk $D$, then given an extra transversality condition the fibration on $S^3\setminusν(K)$ extends to a fibration of $B^4\setminusν(D)$. This partially answers a question of Casson and Gordon. In particular, we show the fibration always extends when $D$ has exactly two local minima. More generally, we construct movies of singular fibrations on $4$-manifolds and describe a sufficient property of a movie to imply the underlying $4$-manifold is fibered over $S^1$.

description: Downlink channel estimation with low pilot overhead is an important and challenging problem in large-scale MIMO systems due to the substantially increased MIMO channel dimension. In this letter, we propose a block iterative support detection (block-ISD) based algorithm for downlink channel estimation to reduce the pilot overhead, which is achieved by fully exploiting the block sparsity inherent in the block-sparse equivalent channel derived from the spatial correlations of MIMO channels. Furthermore, unlike conventional compressive sensing (CS) algorithms that rely on prior knowledge of the sparsity level, block-ISD relaxes this demanding requirement and is thus more practically appealing. Simulation results demonstrate that block-ISD yields better normalized mean square error (NMSE) performance than classical CS algorithms, and achieve a reduction of 84% pilot overhead than conventional channel estimation techniques.

description: Contexte : La dépression post-partum provoque chez la femme des répercussions importantes concernant son rôle de mère et est sous-diagnostiquée, engendrant une perturbation de la systémique familiale. Objectif : Identifier les interventions infirmières auprès des femmes souffrant de dépression postpartum incluant la systémique familiale. Méthode : Deux bases de données ont été utilisées : CINAHL et PubMed. Les équations de recherche ainsi que les critères d’inclusion et d’exclusion ont permis de sélectionner cinq articles. Ils sont analysés en se référant à la grille de Fortin. Les contenus des articles ont été articulés à l’aide du modèle de McGill. Résultats : Les femmes ne parviennent pas à mettre en place des stratégies de coping satisfaisantes. Elles sont favorables pour un accompagnement infirmier/ère, des conseils et un dépistage. Des interventions telles que des entretiens d’écoute ou un programme de psychoéducation réduiraient les symptômes dépressifs. La conséquence de la dépression post-partum sur les hommes engendre une augmentation des responsabilités et des stratégies de coping et d’apprentissage ressenties comme inefficaces. Discussion : Diverses hypothèses de prises en soins sont envisageables dans la dépression postpartum. Le soutien social, l’inclusion du conjoint, l’accompagnement, la prise en charge pluridisciplinaire ainsi que la mise en place d’interventions durant l’hospitalisation, au retour à domicile, évaluées par l’infirmier/ère et basées sur les besoins des femmes. L’apprentissage permet aux mères et à l’entourage la mise en place de stratégies de coping pouvant réduire les symptômes dépressifs.

description: Let $x\geqslant 3$. For $1\leqslant n\leqslant x$ an integer, let $ω(n)$ be its number of distinct prime factors. We show that $ω(n-1)$ satisfies an Erdős-Kac type theorem whenever $ω(n)=k$ where $1\leqslant k\ll\log\log x$, thus extending a result of Halberstam.

description: This letter documents a search for flavour-changing neutral currents (FCNCs), which are strongly suppressed in the Standard Model, in events with a photon and a top quark with the ATLAS detector. The analysis uses data collected in $pp$ collisions at $\sqrt{s} = 13$ TeV during Run 2 of the LHC, corresponding to an integrated luminosity of 139 fb$^{-1}$. Both FCNC top-quark production and decay are considered. The final state consists of a charged lepton, missing transverse momentum, a $b$-tagged jet, one high-momentum photon and possibly additional jets. A multiclass deep neural network is used to classify events either as signal in one of the two categories, FCNC production or decay, or as background. No significant excess of events over the background prediction is observed and 95% CL upper limits are placed on the strength of left- and right-handed FCNC interactions. The 95% CL bounds on the branching fractions for the FCNC top-quark decays, estimated from both top-quark production and decay, are $\mathcal{B}(t\rightarrow u\gamma) < 0.85 \times 10^{-5}$ and $\mathcal{B}(t\to c\gamma) < 4.2 \times 10^{-5}$ for a left-handed $tq\gamma$ coupling, and $\mathcal{B}(t\to u\gamma) < 1.2 \times 10^{-5}$ and $\mathcal{B}(t\to c\gamma) < 4.5 \times 10^{-5}$ for a right-handed coupling.

description: We have investigated the thermal rectification phenomenon in a single-wall mass graded carbon nanotube by molecular dynamics simulation. Second generation Brenner potential has been used to model the inter atomic carbon interaction. Fixed boundary condition has been taken into account. We compare our findings to a previous study by Alaghemandi et al which has been done with a different potential and boundary condition. The dependence of the rectification factor $R$ on temperature, nanotube diameter and length as well as mass gradient are obtained. It is shown that by increasing the temperature, the rectification decreases whereas by increasing the other parameters namely the mass gradient, diameter and the tube length it increases.

description: A digital control of superconducting cavities for a linear accelerator is presented. The LLRF - Low Level Radio Frequency system for FLASH project in DESY is introduced. FPGA based controller supported by MATLAB system was developed to investigate the novel firmware implementation. Algebraic model in complex domain is proposed for the system analyzing. Calibration procedure of a signal path is considered for a multi-channel control. Identification of the system parameters is carried out by the least squares method application. Control tables: Feed-Forward and Set-Point are determined for the required cavity performance, according to the recognized process. Feedback loop is tuned by fitting a complex gain of a corrector unit. Adaptive control algorithm is applied for feed-forward and feedback modes. Experimental results are presented for a cavity representative operation.

description: Contexte : La mucoviscidose est la maladie chronique la plus fréquente en pédiatrie. De nombreuses recherches scientifiques faites ces dernières années ont permis d’allonger l’espérance de vie des enfants, en optimisant les traitements. Cette avancée scientifique a fait évoluer les besoins des familles dans leur prise en soin hospitalière. Objectif : L’objectif de cette revue de littérature est d’identifier les interventions infirmières de type psychosocial pouvant être mises en place auprès des familles, ayant un enfant d’âge scolaire atteint de mucoviscidose, afin d’obtenir une prise en soin systémique de qualité. Méthode : Deux bases de données ont été consultées afin de trouver des articles scientifiques répondant à la thématique du travail. Six articles ont été sélectionnés grâce aux critères d’inclusion et d’exclusion et analysés afin d’extraire les résultats se référant à la question de recherche. Ces derniers ont été articulés à l’aide de l’approche systémique familiale en soins infirmiers de Calgary. Résultats : Les résultats sont de type descriptif, tel que le ressenti des familles concernant leur quotidien avec leur enfant atteint de mucoviscidose et leur vécu dans le milieu des soins chroniques. Ceci a permis d’articuler les résultats avec un modèle d’évaluation et d’intervention sur la systémique familiale. Conclusion : Une prise en soin psychosociale est essentielle pour les familles d’enfant atteint de mucoviscidose afin de promouvoir leur bonne santé psychique, physique et renforcer l’adhésion au milieu de soin, indispensable dans le cas d’une maladie chronique.

description: Contexte : La prise en charge aux urgences des femmes adultes victimes de violences sexuelles en Suisse varie d’un canton à l’autre. Dans ces situations, l’infirmière dispose de peu d’autonomie et une grande responsabilité repose sur les épaules de la victime pour entamer des démarches (suivi psychochologique, aspect légal, etc.). Le système SANE employé aux Etats-Unis fait intervenir des infirmières spécialisées qui ont pour mission d’accompagner les victimes aussi bien sur le plan somatique que psychiatrique, administratif et jucidiaire. Objectif : Démontrer les bénéfices de la prise en charge SANE et établir la possibilité d’un tel programme en Suisse. Méthode : Plusieurs articles ont été sélectionnés dans les bases de données CINAHL et PubMed à l’aide de mots clés traduits dans leurs thésaurus respectifs puis triés selon des critères précis. Cinq des articles choisis ont été analysés puis leurs résultats classés par thématiques. Résultats : Quatre concepts spécifiques à la prise en charge SANE ressortent des résultats : la nécéssité d’une prise en charge globale des victimes de violences sexuelles, le potentiel de l’interdisciplinarité, le bénéfice de la centralisation des services et la facilitation des démarches judiciaires. Ces concepts s’insèrent dans le cadre de la théorie de la transition de Meleis. Conclusion : Le système SANE déjà bien ancré aux USA depuis plusieurs années, provoque une remise en question du rôle et de la responsabilité infirmière actuels en Suisse.

description: We demonstrate the use of symbolic regression in deriving analytical formulas, which are needed at various stages of a typical experimental analysis in collider phenomenology. As a first application, we consider kinematic variables like the stransverse mass, $M_{T2}$, which are defined algorithmically through an optimization procedure and not in terms of an analytical formula. We then train a symbolic regression and obtain the correct analytical expressions for all known special cases of $M_{T2}$ in the literature. As a second application, we reproduce the correct analytical expression for a next-to-leading order (NLO) kinematic distribution from data, which is simulated with a NLO event generator. Finally, we derive analytical approximations for the NLO kinematic distributions after detector simulation, for which no known analytical formulas currently exist.

Crystal Hall effect in Collinear Antiferromagnets

description: Electrons, commonly moving along the applied electric field, acquire in certain magnets a dissipationless transverse velocity. This spontaneous Hall effect, discovered more than a century ago, has been understood in terms of the time-reversal symmetry breaking by the internal spin-structure of a ferromagnetic, noncolinear antiferromagnetic or skyrmionic form. Here we identify previously overlooked robust Hall effect mechanism arising from collinear antiferromagnetism combined with nonmagnetic atoms at non-centrosymmetric positions. We predict a large magnitude of this crystal Hall effect in a room-temperature collinear antiferromagnet RuO$_2$ and catalogue, based on our symmetry rules, extensive families of material candidates. We show that the crystal Hall effect is accompanied by the possibility to control its sign by the crystal chirality. We illustrate that accounting for the full magnetization density distribution instead of the simplified spin-structure sheds new light on symmetry breaking phenomena in complex magnets and opens an alternative avenue towards quantum materials engineering for low-dissipation nanoelectronics.
