description: We study an inverse parabolic problem of identifying two source terms in heat equation with dynamic boundary conditions from a final time overdetermination data. Using a weak solution approach by Hasanov, the associated cost functional is analyzed, especially a gradient formula of the functional is proved and given in terms of the solution of an adjoint problem. Next, the existence and uniqueness of a quasi-solution are also investigated. Finally, the numerical reconstruction of some heat sources in a 1-D equation is presented to show the efficiency of the proposed algorithm.

description: As is well known to physicists, the axial anomaly of the massless free fermion in Euclidean signature is given by the index of the corresponding Dirac operator. We use the Batalin-Vilkovisky (BV) formalism and the methods of equivariant quantization of Costello and Gwilliam to produce a new, mathematical derivation of this result. Using these methods, we formalize two conventional interpretations of the axial anomaly, the first as a violation of current conservation at the quantum level and the second as the obstruction to the existence of a well-defined fermionic partition function. Moreover, in the formalism of Costello and Gwilliam, anomalies are measured by cohomology classes in a certain obstruction-deformation complex. Our main result shows that---in the case of the axial symmetry---the relevant complex is quasi-isomorphic to the complex of de Rham forms of the spacetime manifold and that the anomaly corresponds to a top-degree cohomology class which is trivial if and only if the index of the corresponding Dirac operator is zero.

description: Das Exposé geht der Frage nach, ob und wie sich das in jüngerer Zeit etablierte Politikfeld Baukultur als Konzept mit ganzheitlichem Anspruch für eine vermehrt qualitative Diskussion und Weiterentwicklung der Raumplanung fruchtbar machen lässt. Eine Differenzierung der Beziehung von Raumplanung und Baukultur in drei Schritten kommt zum Schluss, dass beide Politikfelder dem gemeinsamen Ziel einer nachhaltigen Gestaltung des Lebensraums verpflichtet sind und sich diesem Ziel aus verschiedenen Richtungen nähern. Trennend wirkt, dass beide einen Hegemonieanspruch erheben (Baukultur als Teil der Raumplanung versus Raumplanung als Teil der Baukultur). Verbindend wirken die Öffnung des Bauens vom einzelnen Objekt zum Lebensraum als Ganzem, das Eintreten für die transversale Verankerung der Baukultur und ihre Wertung als Mehrwert für die Förderung des Qualitätsbewusstseins, das Bekenntnis zu einer kulturell fundierten Nachhaltigkeit, die Bejahung von Interdisziplinarität und Zusammenarbeit sowie die Anerkennung von Klimafragen als zentrale Herausforderung für beide Politikfelder. Als Nebeneffekt arbeitet das Exposé Besonderheiten des Schweizer Ansatzes im internationalen Baukulturdiskurs heraus: die Ergänzung der disziplinären Weitung (Baukultur – mehr als Architektur) um eine zeitliche Öffnung (Baukultur – mehr als Heimatschutz), das Ringen um «Baukultur als kulturelle Leistung», die Etablierung des normativen Begriffs «hohe Baukultur», die Operationalisierung von Qualität unter Einschluss des Kriteriums «Schönheit» sowie ein politisches System, dass auch aus der Kultur heraus transversale Lösungsansätze mit internationaler Ausstrahlung anstossen kann. Damit Baukultur und Raumplanung ihr Potenzial für ein besseres Leben in einem besser gestalteten Lebensraum ausschöpfen können, müssen sie stärker zusammenarbeiten.

description: L'ensemble de ces notes ont été crée par John Baldwin lors d'une de ses premières périodes de résidence à Paris. Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.
Les données ainsi que les images des fiches sont accessibles sur le site Internet à l'adresse suivante : http://studium-baldwin.lamop.fr/.

description: In this paper we discuss a hybridised method for FEM-BEM coupling. The coupling from both sides use a Nitsche type approach to couple to the trace variable. This leads to a formulation that is robust and flexible with respect to approximation spaces and can easily be combined as a building block with other hybridised methods. Energy error norm estimates and the convergence of Jacobi iterations are proved and the performance of the method is illustrated on some computational examples.

description: Accurate medical image segmentation is essential for diagnosis, surgical planning and many other applications. Convolutional Neural Networks (CNNs) have become the state-of-the-art automatic segmentation methods. However, fully automatic results may still need to be refined to become accurate and robust enough for clinical use. We propose a deep learning-based interactive segmentation method to improve the results obtained by an automatic CNN and to reduce user interactions during refinement for higher accuracy. We use one CNN to obtain an initial automatic segmentation, on which user interactions are added to indicate mis-segmentations. Another CNN takes as input the user interactions with the initial segmentation and gives a refined result. We propose to combine user interactions with CNNs through geodesic distance transforms, and propose a resolution-preserving network that gives a better dense prediction. In addition, we integrate user interactions as hard constraints into a back-propagatable Conditional Random Field. We validated the proposed framework in the context of 2D placenta segmentation from fetal MRI and 3D brain tumor segmentation from FLAIR images. Experimental results show our method achieves a large improvement from automatic CNNs, and obtains comparable and even higher accuracy with fewer user interventions and less time compared with traditional interactive methods.

description: Weltweit befinden sich ständig mehr Menschen auf der Flucht und entsprechend steigt auch in der Schweiz die Zahl der Asylgesuche. Nach Erhalt eines (temporären) Aufenthaltstitels (Status B, F F, F VAA) agieren die Menschen mit Fluchterfahrung als eigenständige Akteur:innen im Wohnungsmarkt. Die Literatur zeigt einerseits auf, welche Strategien Geflüchtete anwenden, um eine Wohnsituation zu finden, und anderseits, welche Bedeutung derselben zukommt. Diese zwei Aspekte werden im Kontext des Kantons Zürich untersucht, in dem sich hauptsächlich das Asylsystem und der hohe Anteil an Mietwohnungen von den bisherigen Forschungen unterscheidet. Zur Erforschung des Wohnzugangs und der Wahrnehmung der jeweiligen Wohnsituation wurden zehn qualitative, leitfadengestützte Interviews mit Geflüchteten geführt und daraus Wohnbiographien erstellt. Diese zeigen auf, dass der Wohnzugang für Geflüchtete im Kanton Zürich aufgrund von strukturellen, aber auch persönlichen Herausforderungen sehr schwierig ist. Bei den strukturellen Herausforderungen stehen neben dem angespannten Wohnungsmarkt das Asylverfahren mit seinen rechtlichen Vorgaben im Vordergrund. Diese führen insbesondere für Menschen mit Status F VAA zu starken Einschränkungen. Um trotz diesen Herausforderungen erfolgreich eine Wohnsituation zu finden, wird oft auf das (migrantische) Freundesnetzwerk zurückgegriffen. Je stärker der Wohnzugang aber informell über eine einzelne Person erfolgt, desto weniger Sicherheit besteht bezüglich der Qualität der Wohnsituation. Viele Wohnbiographien sind daher charakterisiert durch Kompromisse in der Wohnqualität, Abhängigkeitsverhältnisse zu Hauptmietenden und häufige Wohnungswechsel. Trotz aller Einschränkungen werden die Wohnsituationen von den befragten Personen gesamthaft tendenziell positiv bewertet, da die erlangte Selbstständigkeit für alle von grosser Bedeutung ist. Das könnte auch ein Hinweis sein für die künftige öffentliche Unterstützung von Geflüchteten bei der Wohnungssuche.

description: Der fortschreitende Artenverlust und die neuen internationalen Verpflichtungen zur Biodiversität (30% geschützte Land- und Meeresfläche bis 2030) führen zu einer grösseren Dringlichkeit im Naturschutz. Als Folge erarbeiten die Kantone im Moment eine landesweite ökologische Infrastruktur. Mit dieser Entwicklung gehen eine ganze Reihe von raumplanerischen Fragestellungen einher. Wie können oder sollen ökologisch vernetzende Flächen rechtlich gesichert werden? Durch welche Instrumente soll eine ökologische Infrastruktur im Siedlungsraum, die immer eine Überlagerung darstellt, geplant werden? Die vorliegende Arbeit nimmt insbesondere die beginnende Verankerung der Biodiversität in der kommunalen Nutzungsplanung in den Blick. Es existiert keine allgemein anerkannte Planungspraxis für ökologische Vernetzung auf der Gemeindeebene. Vieles wird durch Leitbilder, Konzepte und Richtpläne geregelt, die bislang jedoch nur teilweise in die Nutzungsplanung überführt werden. Der Auftrag der ökologischen Infrastruktur kann als Möglichkeitsfenster für eine entscheidende Verbesserung der ökologischen Vernetzung auf kommunaler Ebene genutzt werden, wenn der Kanton dafür eine verbindliche Grundlage liefert.

Die Basis der Untersuchung bildet eine Sammlung von zwölf Fallbeispielen aus der ganzen Schweiz. Die zwölf Gemeinden werden im Detail auf ihre Planungsinstrumente und deren Verbindlichkeit untersucht. Quervergleiche der Fallbeispiele lassen die Konstruktion eines idealen Planungsverlaufes für ökologische Vernetzung zu. Dabei werden die Partizipation der Bevölkerung und eine phasengerechte Interessenabwägung einbezogen.

In einer Schlussdiskussion wird nochmals auf die gesellschaftliche Dimension der Thematik eingegangen und eine für ökologische Vernetzung als wichtig erachtete vielschichtige Form des Schutzes skizziert. Als weitere planerische Strategie wird das Konzept der «lebensräumlichen Kontinuität» eingeführt, die langfristig und subtil zu einem kollektiveren Selbstverständnis und einem sensibleren Bewusstsein für die Geschichtlichkeit unserer Lebenswelt führen kann.

description: In the setting of high-dimensional linear regression models, we propose two frameworks for constructing pointwise and group confidence sets for penalized estimators which incorporate prior knowledge about the organization of the non-zero coefficients. This is done by desparsifying the estimator as in van de Geer et al. [18] and van de Geer and Stucky [17], then using an appropriate estimator for the precision matrix $Θ$. In order to estimate the precision matrix a corresponding structured matrix norm penalty has to be introduced. After normalization the result is an asymptotic pivot. The asymptotic behavior is studied and simulations are added to study the differences between the two schemes.

Cosmic expansion parametrization: Implication for curvature and $\text{H}_{0}$ tension

description: We propose an analytical parametrization of the comoving distance and Hubble parameter to study the cosmic expansion history beyond the vanilla $Λ$CDM model. The parametrization is generalized enough to include the contribution of spatial curvature and to capture the higher redshift behaviors. With this parameterization, we study the late time cosmic behavior and put constraints on the cosmological parameters like present values of Hubble parameter ($H_{0}$), matter energy density parameter ($Ω_{m0}$), spatial curvature energy density parameter ($Ω_{k0}$) and baryonic matter energy density parameter ($Ω_{b0}$) using different combinations data like CMB (Cosmic microwave background), BAO (baryon acoustic oscillation), and SN (Pantheon sample for type Ia supernovae). We also rigorously study the Hubble tension in the framework of late time modification from the standard $Λ$CDM model. We find that the late time modification of the cosmic expansion can solve the Hubble tension between CMB $\&$ SHOES (local distance ladder observation for $H_{0}$), between CMB+BAO $\&$ SHOES and between CMB+SN $\&$ SHOES, but the late time modification can not solve the Hubble tension between CMB+BAO+SN and SHOES. That means CMB, BAO, and SN data combined put strong enough constraints on $H_{0}$ (even with varying $Ω_{k0}$) and on other background cosmological parameters so that the addition of $H_{0}$ prior from SHOES (or from similar other local distance observations) can not significantly pull the $H_{0}$ value towards the corresponding SHOES value.

Investigation of the chiral antiferromagnetic Heisenberg model using PEPS

Publisher: name: arXiv

Subjects: subject: Strongly Correlated Electrons (cond-mat.str-el)

description: A simple spin-$1/2$ frustrated antiferromagnetic Heisenberg model (AFHM) on the square lattice - including chiral plaquette cyclic terms - was argued [Anne E.B. Nielsen, German Sierra and J. Ignacio Cirac, Nature Communications $\bf 4$, 2864 (2013)] to host a bosonic Kalmeyer-Laughlin (KL) fractional quantum Hall ground state [V. Kalmeyer and R. B. Laughlin, Phys. Rev. Lett. $\bf 59$, 2095 (1987)]. Here, we construct generic families of chiral projected entangled pair states (chiral PEPS) with low bond dimension ($D=3,4,5$) which, upon optimization, provide better variational energies than the KL ansatz. The optimal $D=3$ PEPS exhibits chiral edge modes described by the Wess-Zumino-Witten $SU(2)_1$ model, as expected for the KL spin liquid. However, we find evidence that, in contrast to the KL state, the PEPS spin liquids have power-law dimer-dimer correlations and exhibit a gossamer long-range tail in the spin-spin correlations. We conjecture that these features are genuine to local chiral AFHM on bipartite lattices.

GeV muon beams with picometer-class emittance from electron-photon collisions

description: One of the challenge of future muon colliders is the production of muon beams carrying high phase space densities. In particular the muon beam normalised transverse emittance is a relevant figure of merit to meet luminosity requests. A typical issue impacting the achieved transverse emittance in muon collider schemes so far considered is the phase space dilution caused by coulomb interaction of primary particles propagating into the target where muons are generated. In this study we present a new scheme for muon beam generation occurring in vacuum by interactions of electron and photon beams. Setting the center of mass energy at about twice the threshold (i.e. around $350$ MeV) the normalised emittance of the muon beam generated via muon pair production reaction ($e^-+γ\rightarrow e^-+μ^+/μ^-$) is largely independent on the emittance of the colliding electron beam and is set basically by the excess of transverse momentum in the muon pair creation. In absence of any other mechanism for emittance dilution, the resulting muon beam, with energy in the range of few tens of GeV, is characterised by an ultra-low normalised transverse rms emittance of a few nm rad, corresponding to a geometrical emittance below $10$ pm rad. This opens the way to a new muon collider paradigm based on muon sources conceived with primary colliding beams delivered by $100$ GeV-class energy recovery linacs interacting with hard-X ray free electron lasers. The challenge is to achieve the requested luminosity of the muon collider adopting a strategy of low muon fluxes/currents combined to ultra-low emittances, so to largely reduce also the levels of muon beam-induced background.

description: Several semiconductor quantum dot techniques have been investigated for the generation of entangled photon pairs. Among the other techniques, droplet epitaxy enables the control of the shape, size, density, and emission wavelength of the quantum emitters. However, the fraction of the entanglement-ready quantum dots that can be fabricated with this method is still limited to around 5%, and matching the energy of the entangled photons to atomic transitions (a promising route towards quantum networking) remains an outstanding challenge. Here, we overcome these obstacles by introducing a modified approach to droplet epitaxy on a high symmetry (111)A substrate, where the fundamental crystallization step is performed at a significantly higher temperature as compared to previous reports. Our method drastically improves the yield of entanglement-ready photon sources near the emission wavelength of interest, which can be as high as 95% due to the low values of fine structure splitting and radiative lifetime, together with the reduced exciton dephasing offered by the choice of GaAs/AlGaAs materials. The quantum dots are designed to emit in the operating spectral region of Rb-based slow-light media, providing a viable technology for quantum repeater stations.

description: Automatic Speech Recognition (ASR) systems can be trained to achieve remarkable performance given large amounts of manually transcribed speech, but large labeled data sets can be difficult or expensive to acquire for all languages of interest. In this paper, we review the research literature to identify models and ideas that could lead to fully unsupervised ASR, including unsupervised segmentation of the speech signal, unsupervised mapping from speech segments to text, and semi-supervised models with nominal amounts of labeled examples. The objective of the study is to identify the limitations of what can be learned from speech data alone and to understand the minimum requirements for speech recognition. Identifying these limitations would help optimize the resources and efforts in ASR development for low-resource languages.

description: In this paper, we solve the long-standing fundamental problem of irregular linear--quadratic (LQ) optimal control, which has received significant attention since the 1960s. We derive the optimal controllers via the key technique of finding the analytical solutions to two different forward and backward differential equations (FBDEs). We give a complete solution to the finite-horizon irregular LQ control problem using a new `two-layer optimization' approach. We also obtain the necessary and sufficient condition for the existence of optimal and stabilizing solutions in the infinite-horizon case in terms of solutions to two Riccati equations and the stabilization of one specific system. For the first time, we explore the essential differences between irregular and standard LQ control, making a fundamental contribution to classical LQ control theory. We show that irregular LQ control is totally different from regular control as the irregular controller must guarantee the terminal state constraint of $P_1(T)x(T)=0$.

description: Reginald Benge was in the Merchant Navy before the war. While he was on leave a policeman arrived at his mother's door and he was then (almost "press-ganged") forced into the Royal Naval Auxiliary. He did his training at Lowestoft with other people who were mainly trawlermen. The Royal Navy requisitioned over 200 commercial trawlers and the smaller ones were mainly used as mine sweepers. "They used trawlers with a sweep, to cut the mines and then had to sink them with rifle fire or blow them up with a rifle. "They all were trained to use rifles and they were trained to use everything. I mean, small ships, you had to do everything." This was obviously very dangerous work and many of the trawlers were blown up either by the mines or by German Luftwaffe bombing.He was on the ship HMT (His Majesty's Trawler) Aston Villa which had been hit by German bombers and was then scuttled. They then came back on a Norwegian ship called the Ranen. "The story is they got dressed up as women.", "Some of them had head squares on", " and when the E-Boat came alongside they took the E-Boat over!". They also "had to wave to the German planes", presumably so they did not get bombed by them. A book called Trawlers Go to War also relates these stories.Reginald was at D-Day alongside about 7,000 other ships. He started his career as a Steward but ended up as a Petty Officer He married during the war: "My mother wrote him a letter, if you don't come back and marry me this time, I'm marrying somebody else." As his son remarked, "Stop the war please I want to get married." He never went back to sea after the war and he went into the shipyards as many ex-Royal Navy and Merchant Navy men did.Audio and transcription are attached.

description: Fred Clarke joined the Home Guard in 1939 and would man the searchlights looking for enemy aircraft. He joined the RAF in 1941, did his basic training at RAF Padgate and then moved to Colnbrook in Buckinghamshire it was at Colnbrook that he was injured and hospitalized for several weeks.In 1944, he was stationed in Peshawar in Northern India now part of Pakistan. This housed the RAF squadrons number 5, 20, 28 and 31, the station provided close support for the army units in the northwest frontier. Whilst Fred was in India he was able to send a message to his wife through the British Broadcasting Corporation (BBC). This was reported in the local newspaper the Shields Gazette with the story that his six-month-old daughter would be able to hear her father's voice for the first time.The RAF played a key role in halting the Japanese Army in Burma with an air strike on their base in Arakan and other bases in Northern Thailand. Fred Clarke served in India until 1946.Audio and transcription are attached.

description: Schematic showing ABR wave I extraction and analysis. Peak (P1) and trough (T1) values of wave I of the ABR traces (wave shaded in blue) were automatically extracted at stimuli levels from 55 to 85 dB SPL using a MatLab script. Wave I amplitudes were then plotted as a function of the stimuli levels. SigmaPlot was used to perform linear regression (dotted line) and calculate the slope (solid lines). Slopes were then compared between the different groups at 16 kHz. (PDF 471 kb)

description: Quantum information is typically encoded in the state of a qubit that is decoupled from the environment. In contrast, waveguide quantum electrodynamics studies qubits coupled to a mode continuum, exposing them to a loss channel and causing quantum information to be lost before coherent operations can be performed. Here we restore coherence by realizing a dark state that exploits symmetry properties and interactions between four qubits. Dark states decouple from the waveguide and are thus a valuable resource for quantum information but also come with a challenge: they cannot be controlled by the waveguide drive. We overcome this problem by designing a drive that utilizes the symmetry properties of the collective state manifold allowing us to selectively drive both bright and dark states. The decay time of the dark state exceeds that of the waveguide-limited single qubit by more than two orders of magnitude. Spectroscopy on the second excitation manifold provides further insight into the level structure of the hybridized system. Our experiment paves the way for implementations of quantum many-body physics in waveguides and the realization of quantum information protocols using decoherence-free subspaces.

description: Sustaining exotic quantum mechanical phases at high temperatures is a long-standing goal of condensed matter physics. Among them, half-metals are spin-polarized conductors that are essential for realizing room-temperature spin current sources. However, typical half-metals are low-temperature phases whose spin polarization rapidly deteriorates with temperature increase. Here, we first show that a low-temperature insulator with an unequal charge gap for the two spin channels can arise from competing Mott and band insulating tendencies. We establish that thermal fluctuations can drive this insulator to a half-metal through a first-order phase transition by closing the charge gap for one spin channel. This half-metal has 100% spin polarization at the onset temperature of metallization. Further, varying the strength of electron repulsion can enhance the onset temperature while preserving spin polarization. We outline experimental scenarios for realizing this tunable finite temperature half-metal.

SPATIAL DEVELOPMENT (PHYSICAL PLANNING)

description: Die heutige Zeit ist geprägt von vielschichtigen Krisen wie dem Klimawandel, endliche Ressourcen und sozialer Ungleichheit. Dies betont die Dringlichkeit von transformativen Massnahmen, die gleichermassen sozial und ökologisch ausgerichtet sein müssen. In diesem Kontext spielt die Raumentwicklung und Bauaktivitäten eine entscheidende Rolle. Konkret geht es in der Schweiz, um eine nachhaltige Transformation des Gebäudebestands sowie um die Minimierung von Ersatzneubauten, die momentan die Bauaktivitäten dominieren, weil Ersatzneubauten aus sozialer und ökologischer Sicht nicht nachhaltig sind. Zudem zeigt die Forschung, dass soziale und ökologische Begleitmassnahmen auch die Akzeptanz von Wohnbautätigkeiten in der Bevölkerung erhöhen. Es ist an der Zeit, dass alle Akteure der Raumentwicklung die Herausforderung der sozial-ökologischen Transformation gemeinsam angehen.

description: The optimal operation of transportation networks is often susceptible to unexpected disruptions, such as traffic incidents and social events. Many established control strategies rely on mathematical models that struggle to cope with real-world uncertainties, leading to a significant decline in effectiveness when faced with substantial disruptions. While previous research works have dedicated efforts to improving the robustness or resilience of transportation systems against disruptions, this paper applies the cutting-edge concept of antifragility to better design a traffic control strategy for urban road networks. Antifragility sets itself apart from robustness and resilience as it represents a system's ability to not only withstand stressors, shocks, and volatility but also thrive and enhance performance in the presence of such adversarial events. Hence, modern transportation systems call for solutions that are antifragile. In this work, we propose a model-free deep Reinforcement Learning (RL) scheme to control a two-region urban traffic perimeter network. The system exploits the learning capability of RL under disruptions to achieve antifragility. By monitoring the change rate and curvature of the traffic state with the RL framework, the proposed algorithm anticipates imminent disruptions. An additional term is also integrated into the RL algorithm as redundancy to improve the performance under disruption scenarios. When compared to a state-of-the-art model predictive control approach and a state-of-the-art RL algorithm, our proposed method demonstrates two antifragility-related properties: (a) gradual performance improvement under disruptions of constant magnitude; and (b) increasingly superior performance under growing disruptions.

description: Transcription and translation retrieve and operationalize gene encoded information in cells. These processes are not instantaneous and incur significant delays. In this paper we study Goodwin models of both inducible and repressible operons with state-dependent delays. The paper provides justification and derivation of the model, detailed analysis of the appropriate setting of the corresponding dynamical system, and extensive numerical analysis of its dynamics. Comparison with constant delay models shows significant differences in dynamics that include existence of stable periodic orbits in inducible systems and multistability in repressible systems. A combination of parameter space exploration, numerics, analysis of steady state linearization and bifurcation theory indicates the likely presence of Shilnikov-type homoclinic bifurcations in the repressible operon model.
