description: The $N$-flavor interacting Su-Schrieffer-Heeger (i-SSH) model realizable in cold-atoms in an optical lattice is studied. We clarify the relationship between the i-SSH model and the Chiral-Gross-Neveu-Wilson (CGNW) model. Following the previous study of the CGNW model in the high-energy physics community, the groundstate phases of the i-SSH model are investigated and interpreted from the view of the phases of the CGNW model. The interaction effect on the i-SSH model, belonging to the topological BDI class, is grasped by following the view of the dynamical breakdown of chiral symmetry in the CGNW model. Furthermore, we compare the large-$N$ groundstate phase diagram with that of the $N=1$ case obtained by exact diagonalization and then propose a table-top cold-atom quantum simulator to test the model.

description: The baryons containing two heavy quarks and a light quark are believed to have the diquark-quark structure and the diquark is composed of the two heavy quarks which is a spin-0 or spin-1 object. The superflavor symmetry can associate productions of such heavy baryon-antibaryon pair with the heavy meson productions. The whole scenario is presented in some details in this work, and the observation prospect in future experiments is discussed.

description: Collective excitations in simple metal systems can be described successfully in terms of a local one-body excitation operator Q, due to the long range nature of the coulomb interaction. For the plasmon modes of a simple-metal slab, momentum expansions of Q are calculated using a variational procedure, equivalent to a restricted RPA calculation. The dispersion relation and the density fluctuation for each mode are found in the sudden approximation using the proper Q operator and the RPA sum-rule formalism. The contribution of the exchange and correlation energy is estimated using a local density functional. The positive background is described within a jellium model while the ground-state electronic density is approximated by a double step profile. The density fluctuation of the plasmon modes above the plasma frequency form standing waves across the slab. The spectra below the plasma frequency is qualitatively different to that of local optics calculations, due to the appearance of two multipole plasmon modes that shift down the origin of the $ω_{+}$ plasmon. The dependence of the results on the width of the slab, the density of the simple-metal and the surface diffuseness is discussed. Throughout, we compare our results with previous RPA and TDLDA calculations.

description: High-frequency synchronized vibrations in the friction contact constitute one known triggering mechanism of certaintypes of NVH phenomena in automotive brakes. Towards an improved understanding of the associated physical processes,vibrations of contact patches in the tribological boundary layer are computed using the Abstract Cellular Automaton simulationprogram. Various studies are presented, each illustrating unique types of local phenomena and observable global behaviors. Forexample, simulations are carried out on multiple timescales, enabling investigations into the emergence of global patch coveragestates and the resulting vibrational behavior in the tribological contact. Relevant means for analyzing and interpreting these resultsare introduced, including a qualitative visual representation scheme, frequency analyses of the global coefficient of friction, anda new method for quantifying the synchronization of multiple oscillating bodies.

description: Motivated by the recent CPLEAR measurement on the time-reversal non-invariance, we review the situation concerning the experimental measurements of charge conjugation, parity violation and time reversibility, in systems with non-Hermitean Hamiltonians. This includes in particular neutral meson systems, like K0-barK0, D0-barD0 and B0-barB0. We discuss the formalism that describes particle-antiparticle mixing and time evolution of states, paying particular emphasis to the orthogonality conditions of incoming and outgoing states. As a result, we confirm that the CPLEAR experiment makes a direct measurement of violation of time-reversal without any assumption of unitarity and CPT-violation. The asymmetry which signifies T-violation, is found to be independent of time and decay processes.

Frequencies and Damping rates of a 2D Deformed Trapped Bose gas above the Critical Temperature
Creators: name: Ghosh, Tarun Kanti

subject: FOS: Physical sciences

description: We derive the equation of motion for the velocity fluctuations of a 2D deformed trapped Bose gas above the critical temperature in the hydrodynamical regime. From this equation, we calculate the eigenfrequencies for a few low-lying excitation modes. Using the method of averages, we derive a dispersion relation in a deformed trap that interpolates between the collisionless and hydrodynamic regimes. We make use of this dispersion relation to calculate the frequencies and the damping rates for monopole and quadrupole mode in both the regimes. We also discuss the time evolution of the wave packet width of a Bose gas in a time dependent as well as time independent trap.

description: The indirectly heated carbonate looping (IHCaL) process is a novel technology for capturing CO₂ from the lime and cement industry. The IHCaL process uses lime as solid sorbent, which comprises synergies with lime and cement plants using same solid materials. Another major advantage of the IHCaL process is the high energetic efficiency. Previous pilot tests proved the feasibility of the IHCaL process for applications in the power plant sector. However, the integration of the IHCaL into cement and lime plants, as well as the usability of spent sorbents as educts in such productions, has not yet been tested. This study describes the design and operation of an existing 300 kWₜₕ pilot plant that is adapted for demonstrating the IHCaL process under industrially relevant conditions of lime plants. First results show that the fluidized bed reactor system can be operated under stable conditions and high CO₂ capture rates can be achieved when the temperature and solid inventory in the carbonator are high enough.

description: In contrast to the case of ordinary quantum Hall effect, the resistance of ballistic helical edge channels in typical quantum spin-Hall experiments is non-vanishing, additive and poorly quantized. Here we present a simple argument connecting this qualitative difference with a spin relaxation in the current/voltage leads in an experimentally relevant multi-terminal bar geometry. Both the finite lead resistance and the spin relaxation contribute to a non-vanishing four-terminal edge resistance, explaining poor quantization quality. We show that corrections to the four-terminal and two-terminal resistances in the limit of strong spin relaxation are opposite in sign, making a measurement of the spin relaxation resistance feasible, and estimate the magnitude of the effect in HgTe-based quantum wells.

Overload capacity

description: Throughout the world, the electricity industry is currently undergoing significant restructuring towards deregulation and competition. Under this new framework, the transmission owner does not have a way to recover the money lost due to the overload in the network. This thesis proposes a way to allow the transmission owner to bid the overload capacity in the power market. First, it presents a method to quantify the impact of overload in the lifetime. Based on the lost lifetime it finds the overload cost and marginal cost that will be used in the power market. Then, the power market is studied with and without the overload cost. Finally, the equilibrium is found and the benefits of the overload are analyzed
Polarization of high-energy electrons traversing a laser beam

description: When polarized electrons traverse a region where the laser light is focused their polarization varies even if their energy and direction of motion are not changed. This effect is due to interference of the incoming electron wave and an electron wave scattered at zero angle. Equations are obtained which determine the variation of the electron density matrix, and their solutions are given. The change in the electron polarization depends not only on the Compton cross section but on the real part of the forward Compton amplitude as well. It should be taken into account, for example, in simulations of the $e \to γ$ conversion for future $γγ$ colliders.

title: Risk-aware and Robust Approaches for Machine Learning-supported Model Predictive Control for Iterative Processes
Creators: name: Morabito, Bruno
Publisher: name: UNSPECIFIED
Year: 2024

description: The recent advances in machine learning have catalyzed a renewed interest in machine-learning-supported model predictive control. Machine learning promises to facilitate modeling and improve the process' performance. Nevertheless, it brings some challenges: For instance, as the connection with physics law is (partially) lost, machine learning models can provide wildly inaccurate results. It is therefore necessary to provide control methods that take the model uncertainty of these models into account. Uncertainties are even more important for iterative processes - processes that do not operate at a steady state - due to the large changes in the process conditions during operation.

 In this work, two methods for data-driven uncertainty modelling are proposed. The first method uses Gaussian processes to learn the model uncertainty and neural networks to learn the nominal model. It provides an simple way to summarize the uncertainty of the model into a single parameter, which can be used by a model predictive controller to make risk-aware decisions. This method, while being simple, does not guarantee constraint satisfaction. The second method is based on tube-based model predictive control and can guarantee constraint satisfaction. It is based on the concept of the "safe set": a set where a tube-based MPC has a feasible solution. We show that, under some assumptions, the safe set enlarges at every iteration of the process, potentially allowing increased performance.
Finally, a novel Python library for machine-learning-based model predictive control, called HILO-MPC, is presented. This library interfaces with TensorFlow and PyTorch and provides easily-accesible tools for defining control and estimation problem using machine learning model.

description: Exceptional points are universal level degeneracies induced by non-Hermiticity. Whereas past decades witnessed their new physics, the unified understanding has yet to be obtained. Here we present the complete classification of generic topologically stable exceptional points according to two types of complex-energy gaps and fundamental symmetries of charge conjugation, parity, and time reversal. This classification reveals unique non-Hermitian gapless structures with no Hermitian analogs and systematically predicts unknown non-Hermitian semimetals and nodal superconductors; a topological dumbbell of exceptional points in three dimensions is constructed as an illustration. Our work paves the way toward richer phenomena and functionalities of exceptional points and non-Hermitian topological semimetals.

description: A series of high-quality single crystals of Cu$_{1-x}$Zn$_x$GeO$_3$ have been examined by neutron scattering techniques. An antiferromagnetic (AF) ordering is confirmed for samples with $x\geq 0.02$, in complete agreement with previous reports. We show that the spin-Peierls (SP) phase transition persists to 6\% Zn, whereas previous magnetic susceptibility measurements reported a deterioration of the SP transition above 2\% Zn. We present some details of the successive transitions upon lowering temperature into the spin-Peierls phase which is followed by a transition into an antiferromagnetically ordered phase. Below the Néel temperature we observe the coexistence of the SP lattice dimerization and AF states.

description: In recent years, there has been a growing interest in applying convolutional neural networks (CNNs) to low-level vision tasks such as denoising and super-resolution. Due to the coherent nature of the image formation process, optical coherence tomography (OCT) images are inevitably affected by noise. This paper proposes a new method named the multi-input fully-convolutional networks (MIFCN) for denoising of OCT images. In contrast to recently proposed natural image denoising CNNs, the proposed architecture allows the exploitation of high degrees of correlation and complementary information among neighboring OCT images through pixel by pixel fusion of multiple FCNs. The parameters of the proposed multi-input architecture are learned by considering the consistency between the overall output and the contribution of each input image. The proposed MIFCN method is compared with the state-of-the-art denoising methods adopted on OCT images of normal and age-related macular degeneration eyes in a quantitative and qualitative manner.

description: We study probability distributions of waves of topplings in the Bak-Tang-Wiesenfeld model on hypercubic lattices for dimensions D>=2. Waves represent relaxation processes which do not contain multiple toppling events. We investigate bulk and boundary waves by means of their correspondence to spanning trees, and by extensive numerical simulations. While the scaling behavior of avalanches is complex and usually not governed by simple scaling laws, we show that the probability distributions for waves display clear power law asymptotic behavior in perfect agreement with the analytical predictions. Critical exponents are obtained for the distributions of radius, area, and duration, of bulk and boundary waves. Relations between them and fractal dimensions of waves are derived. We confirm that the upper critical dimension D_u of the model is 4, and calculate logarithmic corrections to the scaling behavior of waves in D=4. In addition we present analytical estimates for bulk avalanches in dimensions D>=4 and simulation data for avalanches in D<=3. For D=2 they seem not easy to interpret.

description: One of the most important questions in the study of compact objects is the nature of pulsars, including whether they consist of neutron matter or strange quark matter (SQM). However, few mechanisms for distinguishing between these two possibilities have been proposed. The purpose of this paper is to show that a strange star (one made of SQM) will have a vibratory mode with an oscillation frequency of approximately 250 GHz (millimeter wave). This mode corresponds to motion of the center of the expected crust of normal matter relative to the center of the strange quark core, without distortion of either. Radiation from currents generated in the crust at the mode frequency would be a SQM signature. We also consider effects of stellar rotation, estimate power emission and signal-to-noise ratio, and discuss briefly possible mechanisms for exciting the mode.

description: Fontaine-Mazur Conjecture is one of the core statements in modern arithmetic geometry. Several formulations were given since its original statement in 1993, and various angles have been adopted by numerous authors to try to tackle it. Boston's seminal paper in 1992 gave a range of purely group-theoretic methods rather than representation-theoretic ones to prove some special cases of this conjecture. Such methods have been later successfully carried on by Maire and his co-authors, and brings different informations on the objects involved in the conjecture. This survey article aims to review what is known in this direction and to present some interesting related questions the authors work on.

NEUROHUMORAL, CARDIAC, AND INFLAMMATORY INDICATORS IN DETERMINING THE SEVERITY AND PROGRESSION OF HEART FAILURE
Creators: name: Akromov, Iskandar
Publisher: name: Zenodo
Year: 2025

description: Heart failure is a widespread condition among adults, contributing significantly to global morbidity and mortality. Its principal risk factors include coronary artery disease, hypertension, obesity, diabetes mellitus, chronic pulmonary disorders, a family history of cardiovascular disease, and cardiotoxic treatments. A key contributor to poor outcomes in heart failure patients is the ongoing progression of the disease. This review examines the evidence regarding both established and emerging neurohumoral biomarkers for managing and diagnosing heart failure progression. Although numerous biomarkers have been suggested as potentially useful, none yet embody the ideal characteristics needed for effective screening, diagnosis, prognosis, and therapeutic management. Furthermore, the clinical and pathophysiological importance of these biomarkers may vary according to the disease's presentation, stage, and severity. We also discuss the primary classifications of heart failure based on left ventricular ejection fraction—including heart failure with preserved ejection fraction, heart failure with reduced ejection fraction, and the newly defined heart failure with mid-range ejection fraction. Specific biomarker panels may offer varying predictive performance for the progression of heart failure, particularly in forecasting the future course of the disease and in monitoring adverse or reverse left ventricular remodeling. This article aims to provide an overview of both the fundamental and additional mechanisms underlying heart failure progression, contributing to a more comprehensive understanding of its pathogenesis.

After discussing possible types of neutrino mixing for Dirac and Majorana neutrinos and considering in detail the phenomenology of neutrino oscillations in vacuum and matter, we review all existing evidence and indications in favour of neutrino oscillations that have been obtained in the atmospheric, solar and LSND experiments. We present the results of the analyses of the neutrino oscillation data in the framework of mixing of three and four massive neutrinos and investigate possibilities to test the different neutrino mass and mixing schemes obtained in this way. We also discuss briefly future neutrino oscillation experiments.

description: We compute spectral function for $^4$He by combining coupled-cluster theory with an expansion of integral transforms into Chebyshev polynomials. Our method allows to estimate the uncertainty of spectral reconstruction. The properties of the Chebyshev polynomials make the procedure numerically stable and considerably lower in memory usage than the typically employed Lanczos algorithm. We benchmark our predictions with other calculations in the literature and with electron scattering data in the quasi-elastic peak. The spectral function formalism allows one to extend ab-initio lepton-nucleus cross sections into the relativistic regime. This makes it a promising tool for modeling this process at higher energy transfers. The results we present open the door for studies of heavier nuclei, important for the neutrino oscillation programs.

Tabby allows texture design with direct manipulation in the following workflow: 1) select a target surface, 2) sketch and manipulate a texture with 2D drawings, and then 3) generate 3D printing textures onto an arbitrary curved surface. To enable efficient texture creation, Tabby leverages an auto-completion approach which automates the tedious, repetitive process of applying texture, while allowing flexible customization. Our user evaluation study with seven participants confirms that Tabby can effectively support the design exploration of different patterns for both novice and experienced users.

description: Identifying the distribution and patterns of long-lived material stocks in buildings and infrastructure over large areas is a particular challenge. As bottom-up monitoring is time-consuming, top-down information is difficult to retrieve because of the heterogeneity and rather small unit size of buildings and infrastructural features such as roads or rail. Using remote sensing for mapping human settlements and infrastructure seems to be highly suitable to contribute towards the understanding of material stock distribution and patterns. We use optical remote sensing data for large area fraction mapping of urban surface land cover with the purpose of using it as an input to material stock distribution modeling. The method of this study is based on free and globally available Sentinel-2 imagery, which offers a spatial, temporal and spectral resolution that seems promising for man-made infrastructure mapping. We find that machine learning regression with synthetically mixed input spectra can be used to accurately map urban surface fractions with a resolution of 10m to 20m. Time series information enhances the reliability of urban surface material detection because it accounts for the phenology of urban green spaces and resolves the confusion of soil and impervious surfaces in agricultural areas. Time series metrics also encounter the problem to find best image records and, thus, increases the potential to generalize models over time and space. In the context of material stock analysis, accurate decameter resolution urban surface fractions can be a valuable input to large area stock pattern research. Material stocks and flows could possibly be correlated to either surface features or derived products such as urban functional types or infrastructure age. Besides first mapping results, we present possible approaches to link remote sensing results and methods to material stock distribution.
Tracing Identity through Language: Geolinguistic Profiling in Forensic Linguistic Authorship Analysis
Creators: name: Roemling, Dana
Publisher: name: Zenodo

description: Within the domain of forensic linguistic authorship analysis, there exist three analytical dimensions: the assessment of shared authorship among distinct texts (verification/clustering), the determination of an author's identity from a pool of potential authors (attribution), and the investigation into the linguistic attributes exhibited by an author (profiling). In this talk I focus on profiling, an area firmly grounded in sociolinguistic theory, which establishes a link between linguistic markers and personal characteristics. Traditionally, research on profiling has focussed attributes such as age, gender (Argamon et al., 2007), and native language (Perkins & Grant, 2018), often relying on qualitative methodologies within the context of the forensic inquiry. However, the exploration of an author's regional origins remains an underdeveloped area within the academic discourse, particularly within the purview of forensic analysis (Chambers, 1990).

With the prevalence of computational methodologies and large corpora of natural language data, this projects moves away from the traditional approach to dialect profiling by spotting regionalisms and using dictionaries or dialect atlases in the hopes of placing the word in question (cf. Shuy, 2001). Commencing with a succinct introduction to authorship profiling, this talk also introduces the expansive corpus of 21 million German social media posts employed in this project (Hovy & Purschke, 2018). I show that regional dialectal variation textualised in this social media data corresponds to dialect areas in current sociolinguistic research. Additionally, I demonstrate that the data is sufficient for regional profiling and show how it can be used in geolinguistic profiling cases by on-the-fly mapping of linguistic examples. The prospect of automating geolinguistic profiling is also taken into consideration. This study contributes to the research in forensic geolinguistic profiling by aiding current qualitative analyses. While it advances current research in German dialectology, it, more importantly, offers a tool to map any word of interest and thus proposes a methodology that is not based on an analyst’sintuition.

description: Education reform, more specifically efforts to improve teacher education programs, have a long and complex history within the U.S. education system. Lack of qualified teachers, particularly STEM teachers, has implications for the workforce and the future of student engagement in these subjects. In 1997, the University of Texas at Austin implemented the UTeach teacher preparation model to support the needs of future secondary STEM teachers. Beginning in 2008, a cohort of thirteen universities replicated the model, and it has since expanded to 44 universities across the country. This study explores the experiences of graduates of the UTeach program as they enter their first few years as classroom teachers. This analysis was conducted using a phenomenological methodology that yielded descriptive themes representing participants’ experiences as novice STEM teachers. The researcher interviewed seven UTeach graduates who teach at six high schools in the Southwestern region of the U.S. and one middle school on the West Coast. The findings revealed four themes that captured the essence of the experience of the participants: (a) identity; (b) relational capacity; (c) instructional adaptability; and (d) mentor and support relationships. UTeach graduates discussed the influence of the UTeach program on their self-perception of their roles as teachers, and how that identity has evolved to account for their changing teaching contexts. Participants discussed the value of relational capacity as a foundation for developing meaningful instruction for their students. UTeach graduates also perceived the ability to be flexible and innovative in adjusting teaching strategies as an integral part of their instructional success. Lastly, participants placed high value on support relationships, both formal and informal, that were established as part of their connection to the UTeach program and within their current teaching communities. Recommendations for further research include 1) expanding the sample of this study to include a more diverse population of graduates from more UTeach partner sites, 2) exploring the student-centered components of the UTeach model using graduate feedback to examine their utility in practice, 3) examining principals’ and school district perceptions of how well-prepared UTeach graduates are for effectively instructing STEM courses, as measured by school and district performance evaluation metrics
Spin-entanglement wave in a coarse-grained optical lattice

description: In the present work we explore a suitable coarse graining channel as a tool to describe the effective entanglement spreading in a coarse-grained spin-chain with different degrees of resolution. Comparing it with the experimental realizations performed with ultracold atoms, our results suggest that even if we are not able to fully resolve the system, entanglement can still be detected for some coarse graining levels. Furthermore, we show that it is possible to have some information about the "microscopic" entanglement, even if we have access only to the system's coarse-grained description. We show that the amount of entanglement decays exponentially with the lack of system resolution. The lack of experimental resolution might thus lead to an effective classical description.

Phase transitions and noise crosscorrelations in a model of directed polymers in a disordered medium

description: We show that effective interactions mediated by disorder between two directed polymers can be modelled as the crosscorrelation of noises in the Kardar-Parisi-Zhang (KPZ) equations satisfied by the respective free energies of these polymers. When there are two polymers, disorder introduces attractive interactions between them. We analyze the phase diagram in details and show that these interactions lead to new phases in the phase diagram. We show that, even in dimension $d=1$, the two directed polymers see the attraction only if the strength of the disorder potential exceeds a threshold value. We extend our calculations to show that if there are $m$ polymers in the system then $m$-body interactions are generated in the disorder averaged effective free energy.

Absence of Persistent Magnetic Oscillations in Type-II Superconductors

name: MacDonald, A. H.
Publisher: name: arXiv
Year: 1996
Subjects: subject: Condensed Matter (cond-mat)

description: We report on a numerical study intended to examine the possibility that magnetic oscillations persist in type II superconductors beyond the point where the pairing self-energy exceeds the normal state Landau level separation. Our work is based on the self-consistent numerical solution for model superconductors of the Bogoliubov-deGennes equations for the vortex lattice state. In the regime where the pairing self-energy is smaller than the cyclotron energy, magnetic oscillations resulting from Landau level quantization are suppressed by the broadening of quasiparticle Landau levels due to the non-uniform order parameter of the vortex lattice state, and by splittings of the quasiparticle bands. Plausible arguments that the latter effect can lead to a sign change of the fundamental harmonic of the magnetic oscillations when the pairing self-energy is comparable to the cyclotron energy are shown to be flawed. Our calculations indicate that magnetic oscillations are strongly suppressed once the pairing self-energy exceeds the Landau level separation.

description: We consider closed planar curves with fixed length and arbitrary winding number whose elastic energy depends on an additional density variable and a spontaneous curvature. Working with the inclination angle, the associated $L^2$-gradient flow is a nonlocal quasilinear coupled parabolic system of second order. We show local well-posedness, global existence of solutions, and full convergence of the flow for initial data in a weak regularity class.
