description: ZrTe$_5$ and HfTe$_5$ have attracted increasingly attention recently since the theoretical prediction of being topological insulators (TIs). However, subsequent works show many contradictions about their topological nature.Three possible phases, i.e. strong TI, weak TI, and Dirac semi-metal, have been observed in different experiments until now. Essentially whether ZrTe$_5$ or HfTe$_5$ has a band gap or not is still a question. Here, we present detailed first-principles calculations on the electronic and topological properties of ZrTe$_5$ and HfTe$_5$ on variant volumes and clearly demonstrate the topological phase transition from a strong TI, going through an intermediate Dirac semi-metal phase, then to a weak TI when the crystal expands.Our work might give a unified explain about the divergent experimental results and propose the crucial clue to further experiments to elucidate the topological nature of these materials.

Characterizations of ordered operator spaces

description: We demonstrate new abstract characterizations for unital and non-unital operator spaces. We characterize unital operator spaces in terms of the cone of accretive operators (operators whose real part is positive). Defining the gauge of an operator $T \in B(H)$ to be $\|Re(T)_+\|$, we demonstrate an abstract characterization of operator spaces up to complete gauge-isometry. Both of these characterizations preserve the structure of the self-adjoint, positive, and accretive operators, as well as the operator norm. We show that an operator space with a given matrix ordering of positive or accretive cones can be represented completely isometrically and completely order isomorphically if and only if each positive cone is normal, in the sense that $x \leq y \leq z$ implies that $\|y\| \leq \max(\|x\|,\|z\|)$ at each matrix level. This is achieved by showing that normal matrix ordered operator spaces are induced by gauges. We show that inducing gauges are not unique in general. Finally, we show that completely positive completely contractive linear maps on non-unital operator spaces extend to any containing operator system if and only if the operator space is induced by a unique gauge.

We include the known cases, the symmetric matrices and real or complex stochastic matrices, to compare the other results and for completeness. In addition, for a given list of eigenvalues, we compute the exact range for the largest value of the diagonal entries of the various nonnegative matrices.

Compactly-supported Wannier functions and algebraic $K$-theory

description: In a tight-binding lattice model with $n$ orbitals (single-particle states) per site, Wannier functions are $n$-component vector functions of position that fall off rapidly away from some location, and such that a set of them in some sense span all states in a given energy band or set of bands; compactly-supported Wannier functions are such functions that vanish outside a bounded region. They arise not only in band theory, but also in connection with tensor-network states for non-interacting fermion systems, and for flat-band Hamiltonians with strictly short-range hopping matrix elements. In earlier work, it was proved that for general complex band structures (vector bundles) or general complex Hamiltonians---that is, class A in the ten-fold classification of Hamiltonians and band structures---a set of compactly-supported Wannier functions can span the vector bundle only if the bundle is topologically trivial, in any dimension $d$ of space, even when use of an overcomplete set of such functions is permitted. This implied that, for a free-fermion tensor network state with a non-trivial bundle in class A, any strictly short-range parent Hamiltonian must be gapless. Here, this result is extended to all ten symmetry classes of band structures without additional crystallographic symmetries, with the result that in general the non-trivial bundles that can arise from compactly-supported Wannier-type functions are those that may possess, in each of $d$ directions, the non-trivial winding that can occur in the same symmetry class in one dimension, but nothing else. The results are obtained from a very natural usage of algebraic $K$-theory, based on a ring of polynomials in $e^{\pm ik_x}$, $e^{\pm ik_y}$, . . . , which occur as entries in the Fourier-transformed Wannier functions.

Detuning-dependent Properties and Dispersion-induced Instabilities of Temporal Dissipative Kerr Solitons in Optical Microresonators

description: Temporal-dissipative Kerr solitons are self-localized light pulses sustained in driven nonlinear optical resonators. Their realization in microresonators has enabled compact sources of coherent optical frequency combs as well as the study of dissipative solitons. A key parameter of their dynamics is the effective-detuning of the pump laser to the thermally- and Kerr-shifted cavity resonance. Together with the free spectral range and dispersion, it governs the soliton-pulse duration, as predicted by an approximate analytical solution of the Lugiato-Lefever equation. Yet, a precise experimental verification of this relation was lacking so far. Here, by measuring and controlling the effective-detuning, we establish a new way of stabilizing solitons in microresonators and demonstrate that the measured relation linking soliton width and detuning deviates by less than 1 % from the approximate expression, validating its excellent predictive power. Furthermore, a detuning-dependent enhancement of specific comb lines is revealed, due to linear couplings between mode-families. They cause deviations from the predicted comb power evolution, and induce a detuning-dependent soliton recoil that modifies the pulse repetition-rate, explaining its unexpected dependence on laser-detuning. Finally, we observe that detuning-dependent mode-crossings can destabilize the soliton, leading to an unpredicted soliton breathing regime (oscillations of the pulse) that occurs in a normally-stable regime. Our results test the approximate analytical solutions with an unprecedented degree of accuracy and provide new insights into dissipative-soliton dynamics.

description: In this paper we complete the $\mathrm{ADE}$-like classification of simple transitive $2$-representations of Soergel bimodules in finite dihedral type, under the assumption of gradeability. In particular, we use bipartite graphs and zigzag algebras of $\mathrm{ADE}$ type to give an explicit construction of a graded (non-strict) version of all these $2$-representations. Moreover, we give simple combinatorial criteria for when two such $2$-representations are equivalent and for when their Grothendieck groups give rise to isomorphic representations. Finally, our construction also gives a large class of simple transitive $2$-representations in infinite dihedral type for general bipartite graphs.

description: We present a quantum Hall effect of magnons in two-dimensional clean insulating magnets at finite temperature. Through the Aharonov-Casher effect, a magnon moving in an electric field acquires a geometric phase and forms Landau levels in an electric field gradient of sawtooth form. At low temperatures, the lowest energy band being almost flat carries a Chern number associated with a Berry curvature. Appropriately defining the thermal conductance for bosons, we find that the magnon Hall conductances get quantized and show a universal thermomagnetic behavior, i.e., are independent of materials, and obey a Wiedemann-Franz law for magnon transport. We consider magnons with quadratic and linear (Dirac-like) dispersions. Finally, we show that our predictions are within experimental reach for ferromagnets and skyrmion lattices with current device and measurement techniques.

We show the applicability of the method for regression and classification tasks using synthetic data-sets and also a real world example in the financial services industry. Then we demonstrate how the method can be extended for knowledge extraction to select the individual rules in a Bayesian way which best explains the given data. Finally we discuss the advantages and pitfalls of using this method over state-of-the-art techniques and highlight the specific class of problems where this would be useful.

We establish an asymptotic expansion for the $m$-th Fourier component of the Szegő kernel function as $m\rightarrow\infty$, where the expansion involves a contribution in terms of a distance function from lower dimensional strata of the $S^1$ action. We also obtain explicit formulas for the first three coefficients of the expansion.

A Numerical Approach to Stability of Multiclass Queueing Networks

description: The Multi-class Queueing Network (McQN) arises as a natural multi-class extension of the traditional (single-class) Jackson network. In a single-class network subcriticality (i.e. subunitary nominal workload at every station) entails stability, but this is no longer sufficient when jobs/customers of different classes (i.e. with different service requirements and/or routing scheme) visit the same server; therefore, analytical conditions for stability of McQNs are lacking, in general. In this note we design a numerical (simulation-based) method for determining the stability region of a McQN, in terms of arrival rate(s). Our method exploits certain (stochastic) monotonicity properties enjoyed by the associated Markovian queue-configuration process. Stochastic monotonicity is a quite common feature of queueing models and can be easily established in the single-class framework (Jackson networks); recently, also for a wide class of McQNs, including first-come-first-serve (FCFS) networks, monotonicity properties have been established. Here, we provide a minimal set of conditions under which the method performs correctly. Eventually, we illustrate the use of our numerical method by presenting a set of numerical experiments, covering both single and multi-class networks.

description: This paper studies the basic question of whether a given channel $V$ can be dominated (in the precise sense of being more noisy) by a $q$-ary symmetric channel. The concept of "less noisy" relation between channels originated in network information theory (broadcast channels) and is defined in terms of mutual information or Kullback-Leibler divergence. We provide an equivalent characterization in terms of $χ^2$-divergence. Furthermore, we develop a simple criterion for domination by a $q$-ary symmetric channel in terms of the minimum entry of the stochastic matrix defining the channel $V$. The criterion is strengthened for the special case of additive noise channels over finite Abelian groups. Finally, it is shown that domination by a symmetric channel implies (via comparison of Dirichlet forms) a logarithmic Sobolev inequality for the original channel.

description: This deliverable describes raw sequence data processing workflows available for SARS-CoV-2 data hub users and systematic analysis of public data in the COVID-19 Data Portal (DP). Workflows are focused at generating consensus sequences and variant calls from raw read data. This generates a complete data product, with provenance with regards to data owners, data types and processing workflows. The data product is then consumable by the scientific research community, for example epidemiologists who may be interested in the tracking of SARS-CoV-2 infection and specific variants. This deliverable does not cover work on SARS-CoV-2 phylogeny, which has been described in deliverable 8.4, however this is an additional aspect/workflow that is available within the data hubs and utilised for systematically analysis of submitted sequence datasets within the COVID-19 DP. The SARS-CoV-2 data hubs are toolboxes and spaces for users to share data (in a pre-publication or 1 public manner), in some cases with collaborators based in different institutes, automatically process the shared data (through the data hub configuration), with resulting analysis returned back to the data hub for interpretation by users and their collaborators. In some cases (depending on the workflow used to analyse), interactive Jupyter notebooks are also available for users.

description: Digitalization offers great opportunities for standardized measurement data processing and evaluation. This also requires standardized data formats. For lidar measurements in complex terrain, there is no open source software
 available. Currently there are some commercial or in-house correction methods available for the post-processing of lidar measurement data in complex terrain. However, there are currently no comparative studies
 regarding the uncertainty as well as the computational effort for the different methods.
 These open aspects are addressed in the research project “Lidar data correction for sites in complex terrain (LoTar)”. Within this research project an modularized open source framework will be developed for standardized
 and efficient processing and correction of wind profile lidar data in complex terrain. This framework is designed to have a modularized basic structure. As a first step, it is planned that the framework will include a module for lidar error
 estimation and turbulence correction. In addition, the framework will provide interfaces with which further modules for data analysis and data processing can be integrated into the framework.

description: In der mathematikdidaktischen Diskussion wird in den letzten Jahren immer wieder betont, dass ein Lernen auf eigenen Wegen mit einem Lernen von- und miteinander verbunden werden soll. Im Mathematikunterricht der Grundschule finden sich zunehmend aktiv-entdeckende Unterrichtangebote, aber eher in Form individualisierender Differenzierung und weniger in einer durch Kommunikation und Kooperation geprägten Unterrichtskultur. In einem Forschungsprojekt zum kollektiven Problemlösen soll die Aufgabenkultur, die sich für den Mathematikunterricht der Grundschule aus dem Ansatz der "substanziellen Aufgabenformate" (z.B. Wittmann 1995) heraus ausgebildete hat, in kooperativen bzw. kollektiven Lernarrangements im Unterrichtsalltag eingebunden werden. In der forschungsmethodologisch als Design-Based-Research angelegten Studie sollen diese Realisierungen im Unterrichtsalltag genutzt werden, um Wechselbeziehungen zwischen kooperativen und fachlichen Aspekten der Bearbeitungsprozesse zu beleuchten. Grundlage für die Analyse von Strukturen und Strukturierungen entsprechender Lernformen bildet das partizipationstheoretische Modell fachlichen Lernens (Krummheuer & Brandt 2001).

description: The low-energy physics of a superfluid 3He-B is governed by Nambu-Goldstone bosons resulting from its characteristic symmetry breaking pattern. Here we construct an effective field theory at zero temperature consistent with all available symmetries in curved space, which are the U(1) phase x SU(2) spin x SO(3) orbital gauge invariance and the nonrelativistic general coordinate invariance, up to the next-to-leading order in a derivative expansion. The obtained low-energy effective field theory is capable of reproducing gyromagnetic responses of the superfluid 3He-B, such as a magnetization generated by a rotation and an orbital angular momentum density generated by a magnetic field, in a model-independent and nonperturbative way. We furthermore show that the stress tensor exhibits a dissipationless Hall viscosity with coefficients uniquely fixed by the orbital angular momentum density, which manifests itself as an elliptical polarization of sound wave with an induced transverse component.

description: Im Mathematikunterricht werden heute vermehrt Lernumgebungen eingesetzt, deren Bearbeitung zu individuell geprägten Arbeiten führt. Was im eigentlichen Unterricht jedoch "zählt" sind meist nicht Eigenproduktionen, sondern ausschließlich die bei Tests erzielten Zensuren. Zudem überprüfen die Testaufgaben häufig einseitig operative Fertigkeiten. Den Überlegungen der Kinder und den verschiedenen im Unterricht entstehenden Produkten sollte grundsätzlich und beim Einsatz von Lernumgebungen im Speziellen mehr Wertschätzung und damit auch mehr Gewicht zukommen: Bei der Steuerung des weiteren Unterrichts, durch gezielte Auswertungen und persönliche Feedbacks sowie durch ein ganzheitliches, förderorientiertes Beurteilungskonzept. Die nachfolgenden Ausführungen zeigen Möglichkeiten zur förderorientierten Beurteilung und zur Beurteilung im Mathematikunterricht mit Lernumgebungen. Sie wurden in einem Nachfolgeprojekt zum Projekt "Lernumgebungen für Rechenschwache bis Hochbegabte" der pädagogischen Hochschule Aargau erfolgreich erprobt.

description: We study the possibility of determining the octant of the neutrino mixing angle $θ_{23}$, that is, whether $θ_{23}> 45^\circ$ or $θ_{23}<45^\circ$, in long baseline neutrino experiments. Here we numerically derived the sensitivity limits within which these experiments can determine, by measuring the probability of the $ν_μ\to ν_{e}$ transitions, the octant of $θ_{23}$ with a $5σ$ certainty. The interference of the CP violation angle $δ$ with these limits, as well as the effects of the baseline length and the run-time ratio of neutrino and antineutrino modes of the beam have been analyzed.

description: Deliverable Scope Deliverable 8.4. “Phylogenetic tools and enhanced results visualisation” aims at improving navigation and visualisation tools for systematic viral data interpretation, including through phylogenetic trees. As part of task 8.2. Data analysis mobilisation (Objective: mobilisation of analysis upon SARS-CoV-2 sequence data), we intended to deploy the data processing and visualisation components of the SARS-CoV-2 Data Hubs system in order to mobilise viral sequence data analysis at scale. Work accomplished We produced and integrated into the COVID-19 data portal an interactive phylogenetic tree of SARS-CoV-2 consensus sequences data held in the ENA (and INSDC). This tree is built on the Evergreen/PhyloViz architecture developed by collaborators at the Technical University of Denmark (DTU), and integrated as part of the SARS-CoV-2 data hubs. A sequence TSV file is used by the Evergreen tree back end service. A cron-job retrieves this file daily and adds new samples to the MonoDB database. The system also runs a check to detect suspended samples that should be excluded from the tree, and allows this endpoint to be used by the Evergreen/PhyloViz tree generation service and close the circle of the two services. Conclusion The tree regularly updates when new SARS-CoV-2 sequences/genomes are shared with the International Nucleotide Sequence Database Collaboration (INSDC), ensuring only public data is included. The tree is accompanied by an appropriate metadata table and a world map illustrating the country of origin of samples represented in the tree. Improvements are being made to the phylogeny include integration of lineage information, variation information and performance updates.

description: In the realm of cybersecurity, intrusion detection systems (IDS) detect and prevent attacks based on collected computer and network data. In recent research, IDS models have been constructed using machine learning (ML) and deep learning (DL) methods such as Random Forest (RF) and deep neural networks (DNN). Feature selection (FS) can be used to construct faster, more interpretable, and more accurate models. We look at three different FS techniques; RF information gain (RF-IG), correlation feature selection using the Bat Algorithm (CFS-BA), and CFS using the Aquila Optimizer (CFS-AO). Our results show CFS-BA to be the most efficient of the FS methods, building in 55% of the time of the best RF-IG model while achieving 99.99% of its accuracy. This reinforces prior contributions attesting to CFS-BA's accuracy while building upon the relationship between subset size, CFS score, and RF-IG score in final results.

description: En el presente escrito llevaremos inicialmente al lector a través de un recuento historiográfico a hacer un recorrido por esa Colombia de preludios de siglo XX, haciendo énfasis en la memoria histórica del departamento de Bolívar, señalando una deficitaria red de servicios sociales con heterogéneos y complejos episodios administrativos y naturales que delinearon una sociedad fragmentada e inestable con especificidades y tipologías negativas y positivas dando lugar a un tejido urbano poco estructurado, pero con una fuerza social en constante actividad evolutiva que vislumbraba amplios horizontes que la proyectaban a insertarse en la modernidad global. Siguiendo con la lectura encontraremos un breve muestreo de las funciones y competitividades de algunos funcionarios gubernamentales, para luego ubicar al lector en el espacio geográfico del departamento de Bolívar, seguido de una relación sobre los modelos higienistas, su aplicación y su reflejo en la comunidad Bolivarense, por ultimo aportamos los datos recolectados ceñidos a la realidad de nuestra labor investigativa y sujetos a la veracidad de quienes los generan. Dejamos al lector la labor de analizar y concluir la realidad social de la región, no solo del periodo de tiempo en estudio si no de la historia regional en general, es así como aun hoy estando en marcha el siglo XXI continuamos en un letargo social. Por tanto, ponemos a disposición de ustedes este aporte, deseando sea de gran utilidad, animando a generar nuevas medidas correctivas que den a futuro patrones de conducta que influyan en forma positiva y den lugar a una estructura social con un poder de cohesión capaz de impedir las protervas políticas administrativas y afrontar acontecimientos naturales (pandemias, accidentes, desastres naturales etc.) futuros de los que ninguna sociedad está exenta, con medidas expeditas y eficaces.

description: Nondominated sorting, also called Pareto Depth Analysis (PDA), is widely used in multi-objective optimization and has recently found important applications in multi-criteria anomaly detection. Recently, a partial differential equation (PDE) continuum limit was discovered for nondominated sorting leading to a very fast approximate sorting algorithm called PDE-based ranking. We propose in this paper a fast real-time streaming version of the PDA algorithm for anomaly detection that exploits the computational advantages of PDE continuum limits. Furthermore, we derive new PDE continuum limits for sorting points within their nondominated layers and show how the new PDEs can be used to classify anomalies based on which criterion was more significantly violated. We also prove statistical convergence rates for PDE-based ranking, and present the results of numerical experiments with both synthetic and real data.

A closer look at the $R_D$ and $R_{D^*}$ anomalies

description: The measurement of $R_D$ ($R_{D^*}$), the ratio of the branching fraction of $\overline{B} \to D τ\barν_τ(\overline{B} \to D^* τ\barν_τ)$ to that of $\overline{B} \to D l \barν_l (\overline{B} \to D^* l \barν_l)$, shows $1.9 σ$ $(3.3 σ)$ deviation from its Standard Model (SM) prediction. The combined deviation is at the level of $4 σ$ according to the Heavy Flavour Averaging Group (HFAG). In this paper, we perform an effective field theory analysis (at the dimension-6 level) of these potential New Physics (NP) signals assuming $\rm SU(3)_{C} \times SU(2)_{L} \times U(1)_{Y}$ gauge invariance. We first show that, in general, $R_D$ and $R_{D^*}$ are theoretically independent observables and hence, their theoretical predictions are not correlated. We identify the operators that can explain the experimental measurements of $R_D$ and $R_{D^*}$ individually and also together. Motivated by the recent measurement of the $τ$ polarisation in $\overline{B} \to D^* τ\barν_τ$ decay, $P_τ(D^*)$ by the Belle collaboration, we study the impact of a more precise measurement of $P_τ(D^*)$ (and a measurement of $P_τ(D)$) on the various possible NP explanations. Furthermore, we show that the measurement of $R_{D^*}$ in bins of $q^2$, the square of the invariant mass of the lepton-neutrino system, along with the information on $τ$ polarisation and the forward-backward asymmetry of the $τ$ lepton, can completely distinguish the various operator structures. We also provide the full expressions of the double differential decay widths for the individual $τ$ helicities in the presence of all the 10 dimension-6 operators that can contribute to these decays.
