description: In this paper we obtain an exact high dimensional anti-de Sitter (AdS) black hole solution in Einstein-bumblebee gravity theory. This AdS-like black hole can only exist with a linear functional potential of the bumblebee field. We find that the Smarr formula and the first law of black hole thermodynamics can still be constructed in this Lorentz symmetry breaking black hole spacetime as long as its temperature, entropy and volume are slightly modified. We find also that there exist two kinds of phase transition: small-large black hole phase transition and Hawking-Page phase transition, like those of Schwarzschild AdS black hole. After Lorentz symmetry breaking, the black hole mass at divergent point of heat capacity becomes small, and the Gibbs free energy of the meta-stable large black hole is also smaller, showing that the large stable black hole can be more easily formed.

description: We introduce support varieties for rational representations of a linear algebraic group $G$ of exponential type over an algebraically closed field $k$ of characteristic $p > 0$. These varieties are closed subspaces of the space $V(G)$ of all 1-parameter subgroups of $G$. The functor $M \mapsto V(G)_M$ satisfies many of the standard properties of support varieties satisfied by finite groups and other finite group schemes. Furthermore, there is a close relationship between $V(G)_M$ and the family of support varieties $V_r(G)_M$ obtained by restricting the $G$ action to Frobenius kernels $G_{(r)} \subset G$. These support varieties seem particularly appropriate for the investigation of infinite dimensional rational $G$-modules.

description: The rising popularity of explainable artificial intelligence (XAI) to understand high-performing black boxes raised the question of how to evaluate explanations of machine learning (ML) models. While interpretability and explainability are often presented as a subjectively validated binary property, we consider it a multi-faceted concept. We identify 12 conceptual properties, such as Compactness and Correctness, that should be evaluated for comprehensively assessing the quality of an explanation. Our so-called Co-12 properties serve as categorization scheme for systematically reviewing the evaluation practices of more than 300 papers published in the last 7 years at major AI and ML conferences that introduce an XAI method. We find that 1 in 3 papers evaluate exclusively with anecdotal evidence, and 1 in 5 papers evaluate with users. This survey also contributes to the call for objective, quantifiable evaluation methods by presenting an extensive overview of quantitative XAI evaluation methods. Our systematic collection of evaluation methods provides researchers and practitioners with concrete tools to thoroughly validate, benchmark and compare new and existing XAI methods. The Co-12 categorization scheme and our identified evaluation methods open up opportunities to include quantitative metrics as optimization criteria during model training in order to optimize for accuracy and interpretability simultaneously.

description: We propose a noncommutative version of the Euclidean Lie algebra $E_2$. Several types of non-Hermitian Hamiltonian systems expressed in terms of generic combinations of the generators of this algebra are investigated. Using the breakdown of the explicitly constructed Dyson maps as a criterium, we identify the domains in the parameter space in which the Hamiltonians have real energy spectra and determine the exceptional points signifying the crossover into the different types of spontaneously broken PT-symmetric regions with pairs of complex conjugate eigenvalues. We find exceptional points which remain invariant under the deformation as well as exceptional points becoming dependent on the deformation parameter of the algebra.

description: In this paper, a distributed non-model based seeking algorithm which combines the extremum seeking control (ESC) jointly with learning algorithms is proposed to seek a generalized Nash equilibrium (GNE) for a class of noncooperative games with coupled equality constraint. The strategy of each agent is restricted by both the coupled inter-agent constraint and local inequality constraints. Thanks to the ESC, it is unnecessary to know the specific expressions of agents' cost functions and local constraints and to know the strategies of other agents for the implementation of the proposed GNE seeking algorithm. To deal with the coupled constraints, only the Lagrange multiplier is transmitted among agents with some prior information about the coupled constraints. Moreover, a diminishing dither signal is designed in the seeking algorithm to remove undesirable steady-state oscillations. The non-local convergence of the designed seeking algorithm is analyzed via the singular perturbation theory, averaging analysis and Lyapunov stability theory. Numerical examples are given to verify the effectiveness of our proposed method.

description: On March 23, 2005, a large explosion at an oil refinery in Texas City, Texas caused 15 deaths and approximately 170 injuries. Little is known about how such an industrial accident influences concern about environmental health risks. We used measures of environmental health concern about nearby petrochemical production with a sample of Texas City residents to understand patterns of concern and change in concern after an industrial accident, as well as individual and contextual factors associated with those patterns. Survey interviews with residents of Texas City, Texas (N =315) both pre- and postexplosion using a brief Concern About Petrochemical Health Risk Scale (CAPHRS) and other questions were used to collect pertinent predictor information. CAPHRS baseline, postexplosion, and change scores were compared and modeled using ordinary least squares (OLS) regression and a mixed model. Higher preexplosion CAPHRS scores were predicted by younger adults, foreign-born Hispanics, non-Hispanic blacks, lower- and middle-income groups, and those who live with someone who has worked at the petrochemical plants. Higher CAPHRS change scores are predicted by the same variables (except income), as well as proximity to, or perception of, the explosion, and reports of neighborhood damage. Findings suggest these groups’ concern scores could indicate a greater vulnerability to psychological and physical harm generated by concern and stress arising from local petrochemical activities. A clearer understanding of concern about actual environmental health risks in exposed populations may enhance the evolving theory of stress and coping and eventually enable public health professionals to develop appropriate mitigation strategies.
Topologically Twisted $N=(2,2)$ Supersymmetric Yang-Mills Theory on Arbitrary Discretized Riemann Surface

description: We define supersymmetric Yang-Mills theory on an arbitrary two-dimensional lattice (polygon decomposition) with preserving one supercharge. When a smooth Riemann surface $Σ_g$ with genus $g$ emerges as an appropriate continuum limit of the generic lattice, the discretized theory becomes topologically twisted $\mathcal{N}=(2,2)$ supersymmetric Yang-Mills theory on $Σ_g$. If we adopt the usual square lattice as a special case of the discretization, our formulation is identical with Sugino's lattice model. Although the tuning of parameters is generally required while taking the continuum limit, the number of the necessary parameters is at most two because of the gauge symmetry and the supersymmetry. In particular, we do not need any fine-tuning if we arrange the theory so as to possess an extra global U(1) symmetry ($U(1)_{R}$ symmetry) which rotates the scalar fields.

description: In Schaltstellen und Trafostationen mit Fernwirkanbindung, bei welchen keine wirtschaftliche Möglichkeit besteht eine kabelgebundene Datenübertragung umzusetzen, kommt eine drahtlose Datenübertragung zum Einsatz. Zielsetzung ist es, eine geeignete Funktechnologie zu finden, welche von der Energie Steiermark selbst betrieben und instandgehalten werden kann ohne von einem öffentlichen Mobilfunknetz abhängig zu sein. Nach dem Vergleich diverser Funktechnologien und der Auswahl einer geeigneten, wurden Tests durchgeführt um die Praxistauglichkeit dieser Funktechnologie zu ermitteln. In den Tests wurde unter anderem auf Gesichtspunkte wie Paketumlaufzeiten, Datendurchsatz und Konsistenz der übertragenen Daten geachtet. Neben dem Test der Praxistauglichkeit sind während der Testphase ebenfalls verschiedene Einstellungen für eine stabile Datenübertragung ermittelt und getestet worden. Die Praxistests und Datenanalysen haben gezeigt, dass die Anforderungen, welche die Energie Steiermark an eine drahtlose Datenübertragung stellt, erfüllt wurden. Wenn Smart Meter auch mit dieser Technologie implementiert werden müssen gegebenenfalls die Einstellungen der Datenübertragung angepasst werden.
description: Wireless technology must be applied for switching stations and transformer stations when data transfer with hard-wired technology is not practical. The wireless technology which is currently implemented at Energie Steiermark utilises a public network which is operated by a third-party supplier. Maintenance work in this public network often causes connection failures which lead to blackouts in the SCADA-System. The aim of this thesis is to compare various wireless technologies and select a suitable technology. Tests and analysis of the transmitted data, such as round-trip time, data throughput and consistency of transmitted data have to carried out to ensure the chosen technology operates as requested. The tests are also needed to identify the ideal settings for a stable data connection. The analysis demonstrated that the requirements from Energie Steiermark of a wireless data transmission were met. In conclusion, it can be stated that the selected wireless technology for data transmission functions reliable and is meanwhile implemented in the production system. Furthermore, if smart meters were also implemented with this technology, the settings of the data transmission would have to be adjusted.

Linear Viscoelastic Response of the Vertex Model with Internal and External Dissipation: Normal Modes Analysis

description: We use the normal mode formalism to study the shear rheology of the vertex model for epithelial tissue mechanics in the overdamped linear response regime. We consider systems with external (e.g., cell-substrate) and internal (e.g., cell-cell) dissipation mechanisms, and derive expressions for stresses on cells due to mechanical and dissipative forces. The semi-analytical method developed here is, however, general and can be directly applied to study the linear response of a broad class of soft matter systems with internal and external dissipation. It involves normal mode decomposition to calculate linear loss and storage moduli of the system. Specifically, displacements along each normal mode produce stresses due to elastic deformation and internal dissipation, which are in force balance with loads due to external dissipation. Each normal mode responds with a characteristic relaxation timescale, and its rheological behavior can be described as a combination of a standard linear solid element due to elastic stresses and a Jeffreys model element due to the internal dissipative stresses. The total response of the system is then fully determined by connecting in parallel all the viscoelastic elements corresponding to individual normal modes. This allows full characterization of the potentially complex linear rheological response of the system at all driving frequencies and identification of collective excitations. We show that internal and external dissipation mechanisms lead to qualitatively different rheological behaviors due to the presence or absence of Jeffreys elements, which is particularly pronounced at high driving frequencies. Our findings, therefore, underscore the importance of microscopic dissipation mechanisms in understanding the rheological behavior of soft materials and tissues, in particular.

description: The basic constituent of interferometric gravitational wave detectors -- the test mass to test mass interferometric link -- behaves as a differential dynamometer measuring effective differential forces, comprising an integrated measure of gravity curvature, inertial effects, as well as non-gravitational spurious forces. This last contribution is going to be characterised by the LISA Pathfinder mission, a technology precursor of future space-borne detectors like eLISA. Changing the perspective from displacement to acceleration can benefit the data analysis of LISA Pathfinder and future detectors. The response in differential acceleration to gravitational waves is derived for a space-based detector's interferometric link. The acceleration formalism can also be integrated into time delay interferometry by building up the unequal-arm Michelson differential acceleration combination. The differential acceleration is nominally insensitive to the system free evolution dominating the slow displacement dynamics of low-frequency detectors. Working with acceleration also provides an effective way to subtract measured signals acting as systematics, including the actuation forces. Because of the strong similarity with the equations of motion, the optimal subtraction of systematic signals, known within some amplitude and time shift, with the focus on measuring the noise provides an effective way to solve the problem and marginalise over nuisance parameters. The $\mathcal{F}$-statistic, in widespread use throughout the gravitation waves community, is included in the method and suitably generalised to marginalise over linear parameters and noise at the same time. The method is applied to LPF simulator data and, thanks to its generality, can also be applied to the data reduction and analysis of future gravitational wave detectors.

We investigate how such states can persist in the presence of a sheared flow. We focus our attention on the pressure tensor equation in a magnetized plasma and derive analytical self-consistent plasma equilibria which exhibit a novel asymmetry with respect to the magnetic field direction. These results are relevant for investigating, within fluid models that retain the full pressure tensor dynamics, plasma configurations where a background shear flow is present.

Wie sieht eine konkrete Umsetzung des gewählten Konzeptes aus? Gegliedert ist die Arbeit in einen theoretischen und praktischen Teil. Der Theorieteil beschäftigt sich mit schienengeführten Systemen und der Korrosionsbeständigkeit von Metallen im Außenbereich, insbesondere für den Einsatz in der Nähe von Salzwasser. Der praktische Teil zeigt die Konzeptionierung nach der VDI 2221 Richtlinie, welche allgemein den Vorgang einer Produktentwicklung beschreibt. Aus dem Konzept entsteht eine konkrete Konstruktion dieser Abdeckung für einen vorgegebenen Pool. Die Erkenntnisse dieser Arbeit sind Lösungsansätze für geeignete Führungssysteme und Materialien, sowie eine neue Variante zur Abdeckung von Schwimmbädern.
description: The following master’s thesis deals with the conceptual design of a split and walkable pool cover and answers the following questions: Which concept is best suited to realize a split walkable pool cover, which should function as a terrace? What does a concrete implementation of the chosen concept look like? The work is structured in a theoretical and a practical part. The theoretical part focuses on rail-guided systems and the corrosion resistance of metals in outdoor areas, especially for use in the vicinity of saltwater. The practical part includes the conception according to the VDI 2221 guideline, which is developed for an abstract product development. The resulting concept leads to a concrete construction of a cover for a predefined pool. The findings of this work are based on literature research and the methodical determination of new solution approaches. This results in suitable rail-guided systems and materials, as well as a new variant for covering swimming pools.

description: Measurements of secular period change probe real-time stellar evolution of classical Cepheids making these measurements powerful constraints for stellar evolution models, especially when coupled with interferometric measurements. In this work, we present stellar evolution models and measured rates of period change for two Galactic Cepheids: Polaris and l Carinae, both important Cepheids for anchoring the Cepheid Leavitt law (period-luminosity relation). The combination of previously-measured parallaxes, interferometric angular diameters and rates of period change allows for predictions of Cepheid mass loss and stellar mass. Using the stellar evolution models, We find that l Car has a mass of about 9 $M_\odot$ consistent with stellar pulsation models, but is not undergoing enhanced stellar mass loss. Conversely, the rate of period change for Polaris requires including enhanced mass-loss rates. We discuss what these different results imply for Cepheid evolution and the mass-loss mechanism on the Cepheid instability strip.

description: Noticing medical symptoms can cause one to search for explanatory labels such as “ate bad food” or even “exposed to anthrax,” and perhaps these labels may cause new symptom reports. The present study examined whether there is empirical support for this symptom-label “symmetry rule.” We interviewed veterans (N = 362) from the Gulf War Registry in 1995 and 2002 about their medical symptoms and about their exposure to war-related hazards and stressors. Health symptom reports were strongly correlated between the two time periods and showed relatively stable mean levels, whereas recall of war-related exposures was notably unstable. Veterans starting with fewer medical symptoms recalled fewer war-related exposures seven years later. Initial recollection of chemical and biological warfare exposure (but not other exposures) longitudinally predicted novel medical symptoms. The findings generally support the symmetry rule hypotheses, although the evidence for the label to symptom link was less strong. The findings account for some variability in symptoms and exposure recall over time, but they do not, on their own, account for the Gulf War veterans’ elevated number of unexplained medical symptoms.

description: Abstract Visual Reasoning (AVR) problems are commonly used to approximate human intelligence. They test the ability of applying previously gained knowledge, experience and skills in a completely new setting, which makes them particularly well-suited for this task. Recently, the AVR problems have become popular as a proxy to study machine intelligence, which has led to emergence of new distinct types of problems and multiple benchmark sets. In this work we review this emerging AVR research and propose a taxonomy to categorise the AVR tasks along 5 dimensions: input shapes, hidden rules, target task, cognitive function, and main challenge. The perspective taken in this survey allows to characterise AVR problems with respect to their shared and distinct properties, provides a unified view on the existing approaches for solving AVR tasks, shows how the AVR problems relate to practical applications, and outlines promising directions for future work. One of them refers to the observation that in the machine learning literature different tasks are considered in isolation, which is in the stark contrast with the way the AVR tasks are used to measure human intelligence, where multiple types of problems are combined within a single IQ test.

description: If the recent detection of $B-$mode polarization of the Cosmic Microwave Background by BICEP2 observations, withstand the test of time after the release of recent PLANCK dust polarisation data, then it would surprisingly put the inflationary scale near Grand Unification scale if one considers single-field inflationary models. On the other hand, Large Hadron Collider has observed the elusive Higgs particle whose presently observed mass can lead to electroweak vacuum instability at high scale $(\sim{\mathcal O}(10^{10})$ GeV). In this article, we seek for a simple particle physics model which can simultaneously keep the vacuum of the theory stable and yield high-scale inflation successfully. To serve our purpose, we extend the Standard Model of particle physics with a $U(1)_{B-L}$ gauged symmetry which spontaneously breaks down just above the inflationary scale. Such a scenario provides a constrained parameter space where both the issues of vacuum stability and high-scale inflation can be successfully accommodated. The threshold effect on the Higgs quartic coupling due to the presence of the heavy inflaton field plays an important role in keeping the electroweak vacuum stable. Furthermore, this scenario is also capable of reheating the universe at the end of inflation. Though the issues of Dark Matter and Dark Energy, which dominate the late-time evolution of our universe, cannot be addressed within this framework, this model successfully describes the early universe dynamics according to the Big Bang model.

description: We predict that a lateral electrical current in antiferromagnets can induce non-equilibrium Néel order fields, i.e. fields whose sign alternates between the spin sublattices, which can trigger ultra-fast spin-axis reorientation. Based on microscopic transport theory calculations we identify staggered current-induced fields analogous to the intra-band and to the intrinsic inter-band spin-orbit fields previously reported in ferromagnets with a broken inversion-symmetry crystal. To illustrate their rich physics and utility, we considered bulk Mn2Au with the two spin sublattices forming inversion partners, and a 2D square-lattice antiferromagnet with broken structural inversion symmetry modelled by a Rashba spin-orbit coupling. We propose an AFM memory device with electrical writing and reading.

description: In a joint work with Palmer we have formulated sufficient conditions under which there exist continuous and invertible transformations of the form $H_n(x,y)$ taking solutions of a coupled system \begin{equation*} x_{n+1} =A_nx_n+f_n(x_n, y_n), \quad y_{n+1}=g_n( y_n), \end{equation*} onto the solutions of the associated partially linearized uncoupled system \begin{equation*} x_{n+1} =A_nx_n, \quad y_{n+1}=g_n( y_n). \end{equation*} In the present work we go one step further and provide conditions under which $H_n$ and $H_n^{-1}$ are smooth in one of the variables $x$ and $y$. We emphasise that our conditions are of a general form and do not involve any kind of dichotomy, nonresonance or spectral gap assumptions for the linear part which are present on most of the related works.

description: CoRoT-7b, the first super-Earth with measured radius discovered, has opened the new field of rocky exoplanets characterisation. To better understand this interesting system, new observations were taken with the CoRoT satellite. During this run 90 new transits were obtained in the imagette mode. These were analysed together with the previous 151 transits obtained in the discovery run and HARPS radial velocity observations to derive accurate system parameters. A difference is found in the posterior probability distribution of the transit parameters between the previous CoRoT run (LRa01) and the new run (LRa06). We propose this is due to an extra noise component in the previous CoRoT run suspected to be transit spot occultation events. These lead to the mean transit shape becoming V-shaped. We show that the extra noise component is dominant at low stellar flux levels and reject these transits in the final analysis. We obtained a planetary radius, $R_p= 1.585\pm0.064\,R_{\oplus}$, in agreement with previous estimates. Combining the planetary radius with the new mass estimates results in a planetary density of $ 1.19 \pm 0.27\, ρ_{\oplus}$ which is consistent with a rocky composition. The CoRoT-7 system remains an excellent test bed for the effects of activity in the derivation of planetary parameters in the shallow transit regime.

description: Taking the supersymmetric inverse seesaw mechanism as the explanation for neutrino oscillation data, we investigate charged lepton flavor violation in radiative and 3-body lepton decays as well as in neutrinoless $μ-e$ conversion in muonic atoms. In contrast to former studies, we take into account all possible contributions: supersymmetric as well as non-supersymmetric. We take CMSSM-like boundary conditions for the soft supersymmetry breaking parameters. We find several regions where cancellations between various contributions exist, reducing the lepton flavor violating rates by an order of magnitude compared to the case where only the dominant contribution is taken into account. This is in particular important for the correct interpretation of existing data as well as for estimating the reach of near future experiments where the sensitivity will be improved by one to two orders of magnitude. Moreover, we demonstrate that ratios like BR($τ\to 3 μ$)/BR($τ\to μe^+ e^-$) can be used to determine whether the supersymmetric contributions dominate over the $W^\pm$ and $H^\pm$ contributions or vice versa.

description: Additional file 3: Figure S3. Double knockdown of nectin-1 and nectin-3 increases spine densities without changing dendrite complexity at P21. a All neurons were electroporated with the Cre-dependent tdTomato and Cre expression constructs shown on the left. Double knockdown neurons were also electroporated with Cre-dependent nectin-1 shRNA and nectin-3 shRNA constructs, shown on the right. Two different controls were included and combined in this experiment: 1) neurons electroporated with only tdTomato and Cre expression constructs (left), and 2) neurons electroporated with tdTomato, Cre, and scramble shRNA expression constructs. b All animals were electroporated at E15.5 (initiating knockdown) and analyzed at P21. c Nectin-1 shRNA successfully knocks down nectin-1 in HEK-293 cells co-transfected with a nectin-1 expression construct and a nectin-1 shRNA construct. Nectin-1 expression/intensity was normalized to α-tubulin and is shown relative to nectin-1 expression when treated with scramble shRNA (analyzed in Image Studio). d Double knockdown of nectin-1 and nectin-3 increases dendritic spine densities relative to control (cells expressing tdTomato alone or tdTomato + scramble shRNA). Left: all double knockdown cells are shown relative to all control cells analyzed. A significant increase in the dendritic spine densities of double knockdown neurons is observed when all dendrites are considered together and when apical dendrites are considered independently (Control: N = 26 cells, 52 dendrites, 8 animals; Nec3 + Nec1-shRNA: N = 11 cells, 22 dendrites, 5 animals). Right: dendritic spine densities for the subset of control and double knockdown cells evaluated using Sholl analysis (Control: N = 8 cells, 16 dendrites, 4 animals; Nec3 + Nec1-shRNA: N = 9 cells, 18 dendrites, 5 animals). e Representative dendrites from double knockdown and control neurons. f Representative double knockdown neuron evaluated using Sholl analysis, which quantifies the number of dendrite crossings at successively larger radii away from the cell body. g Sholl analysis was performed using Imaris image analysis software. No differences were observed between Nec3 + Nec1-shRNA double knockdown neurons and control neurons.

description: Quantum optics with giant atoms has provided a new paradigm to study photon scatterings. In this work, we investigate the nontrivial single-photon scattering properties of giant atoms being an effective platform to realize nonreciprocal and chiral quantum optics. For two-level giant atoms, we identify the condition for nonreciprocal transmission: the external atomic dissipation is further required other than the breaking of time-reversal symmetry by local coupling phases. Especially, in the non-Markovian regime, unconventional revival peaks periodically appear in the reflection spectrum. To explore more interesting scattering behaviors, we extend the two-level giant-atom system to Δ-type and {\nabla}-type three-level giant atoms coupled to double waveguides with different physical mechanisms to realize nonreciprocal and chiral scatterings. Our proposed giant-atom structures have potential applications of high-efficiency targeted routers that can transport single photons to any desired port deterministically and circulators that can transport single photons between four ports in a cyclic way.
The polyribosomal protein bound to the 3' end of histone mRNA can function in histone pre-mRNA processing.

description: Cell cycle-regulated histone mRNAs end in a conserved 26-nt sequence that can form a stem-loop with a six-base stem and a four-base loop. The 3' end of histone mRNA has distinct functions in the nucleus and in the cytoplasm. In the nucleus it functions in pre-mRNA processing and transport, whereas in the cytoplasm it functions in translation and regulation of histone mRNA stability. The stem-loop binding protein (SLBP), present in both nuclei and polyribosomes, is likely the trans-acting factor that binds to the 3' end of mature histone mRNA and mediates its function. A nuclear extract that efficiently processes histone pre-mRNA was prepared from mouse myeloma cells. The factor(s) that bind to the 3' end of histone mRNA can be depleted from this extract using a biotinylated oligonucleotide containing the conserved stem-loop sequence. Using this depleted extract which is deficient in histone pre-mRNA processing, we show that SLBP found in polyribosomes can restore processing, suggesting that SLBP associates with histone pre-mRNA in the nucleus, participates in processing, and then accompanies the mature mRNA to the cytoplasm.

description: Topological insulators are found in materials that have elements with strong spin orbit interaction. However, electron Coulomb repulsion also potentially generates the topological insulators as well as Chern insulators by the mechanism of spontaneous symmetry breaking, which is called topological Mott insulators. The quantum criticality of the transition to the topological Mott insulators from zero-gap semiconductors follows unconventional universality distinct from the Landau-Ginzburg-Wilson scenario. On the pyrochlore lattice, the interplay of the electron correlation and the spin orbit interaction provides us in a rich phase diagram not only with simple topological insulators but also with Weyl semimetal and topologically distinct antiferromagnetic phases. Magnetic domain wall of the all-in-all-out type antiferromagnetic order offers a promising candidate of magnetically controlled transport, because, even when the Weyl points disappears, the domain wall maintains robust gapless excitations with Fermi surfaces around it embedded in the bulk insulator and bears uniform magnetization simultaneously. The ingap state is protected by a mechanism similar to the solitons in polyacetylene. Puzzling experimental results of pyrochlore iridates are favorably compared with the prediction of the domain wall theory.
