description: We report the synthesis and the magnetic susceptibility of (pipdH)2Cu1-xZnxBr4, which is a nonmagnetic impurity-doped S=1/2 spin ladder system. The samples were synthesized from a solution by using a slow evaporation method. Samples were confirmed to be in a single phase and to have the same crystal structure as the pure system (pipdH)2CuBr4 by using X-ray diffraction measurements. To check the magnetic properties, we performed magnetic susceptibility and magnetization measurements with a SQUID magnetometer. A plot of the inverse magnetic susceptibility indicates the presence of dominant antiferromagnetic coupling. The magnetic susceptibility shows a broad maximum due to low dimensionality and a spin gap behavior related to the two-leg spin ladder at low temperature. The spin gap and the Curie constants of Zn-doped samples, as estimated from an analysis of the magnetic susceptibility, monotonically decrease as the Zn concentration decreases. A nonmagnetic impurity of S=1/2 spin ladder system affects the spin gap.

Kondo memory in driven strongly-correlated quantum dots

description: We investigate the real-time current response of strongly-correlated quantum dot systems under sinusoidal driving voltages. By means of an accurate hierarchical equations of motion approach, we demonstrate the presence of prominent memory effects induced by the Kondo resonance on the real-time current response. These memory effects appear as distinctive hysteresis line shapes and self-crossing features in the dynamic current-voltage characteristics, with concomitant excitation of odd-number overtones. They emerge as a cooperative effect of quantum coherence - due to inductive behavior - and electron correlations - due to the Kondo resonance. We also show the suppression of memory effects and the transition to classical behavior as a function of temperature. All these phenomena can be observed in experiments and may lead to novel quantum memory applications.

description: We study a subset of the movie collaboration network, imdb.com, where only adult movies are included. We show that there are many benefits in using such a network, which can serve as a prototype for studying social interactions. We find that the strength of links, i.e., how many times two actors have collaborated with each other, is an important factor that can significantly influence the network topology. We see that when we link all actors in the same movie with each other, the network becomes small-world, lacking a proper modular structure. On the other hand, by imposing a threshold on the minimum number of links two actors should have to be in our studied subset, the network topology becomes naturally fractal. This occurs due to a large number of meaningless links, namely, links connecting actors that did not actually interact. We focus our analysis on the fractal and modular properties of this resulting network, and show that the renormalization group analysis can characterize the self-similar structure of these networks.

description: Phase-resolved transient grating spectroscopy in semiconductor quantum wells has been shown to be a powerful technique for measuring the electron-hole drag resistivity $ρ_{eh}$, which depends on the Coulomb interaction between the carriers. In this paper we develop the interacting drift-diffusion theory, from which $ρ_{eh}$ can be determined, given the measured mobility of an electron-hole grating. From this theory we predict a cross-over from a high-excitation-density regime, in which the mobility has the "normal" positive value, to a low-density regime, in which Coulomb-drag dominates and the mobility becomes negative. At the crossover point, the mobility of the grating vanishes.

description: In this work the glucosinolate (GSL) contents in edible plants and the response of GSL contents to biotic and abiotic stress were analyzed. Fluctuations in GSL contents in Nasturtium officinale were determined in the course of a growing season and in administered N. officinale during a human trial. Results showed only minor changes in GSL contents, which are similar during the development of N. officinale and cultivation of different batches. Hydrolysis of GSLs was analyzed in Moringa oleifera and potential breakdown products were discussed on the basis of structurally related GSLs. Glucosinolate changes were also investigated as a result of biotic stress. Higher contents of gluconasturtiin were observed in Brassica napus infected with Verticillium longisporum. Direct growth inhibitory aspects of gluconasturtiin-derived breakdown products were discussed. Infection of B. napus with Plasmodiophora brassicae on the other hand resulted in lower contents of GSLs. Regulation of gluconasturtiin biosynthesis by more virulent pathotypes might be the cause for differing contents between plants infected with pathotypes differing in their virulence. Furthermore, the influence of abiotic stress on GSL contents in plants was analyzed in this study. Rhythmic GSL fluctuations were observed in B. napus grown in light/dark and continuous light conditions and the influence of the expression of genes involved in biosynthesis and breakdown of GSLs were discussed. The influence of salt stress on Lepidium latifolium revealed significantly higher contents of the aliphatic GSL sinigrin, which might be involved in water homeostasis in the plant. Lastly, it was observed that drought stress resulted in higher contents of the indolic GSL glucobrassicin (GB) in Arabidopsis thaliana. The investigation of deuterium incorporation into GB revealed higher biosynthesis of GB during drought stress. The expression analysis of genes responsible for breakdown of GSLs and synthesis of indole-3-acetic acid (IAA) strongly suggests glucobrassicin as a source of IAA in drought-stressed plants.

Die Art der politischen Theorie, die ich für die politische Dimension meines Projekts gewählt habe, spiegelt diese Sichtweise wider: In allen Kapiteln verbinde ich erkenntnistheoretische Überlegungen mit so genannten agonistischen Theorien der Demokratie. Solche Theorien bieten Möglichkeiten zur produktiven Bearbeitung politischer Konflikte und eine starke Sensibilität für Möglichkeiten, wie solche produktiven Formen von Konflikten in einer Gesellschaft verhindert sein können.

description: The classification of building facade images is a challenging problem that receives a great deal of attention in the photogrammetry community. Image classification is critically dependent on the features. In this paper, we perform an empirical feature evaluation task for building facade images. Feature sets we choose are basic features, color features, histogram features, Peucker features, texture features, and SIFT features. We present an approach for region-wise labeling using an efficient randomized decision forest classifier and local features. We conduct our experiments with building facade image classification on the eTRIMS dataset, where our focus is the object classes building, car, door, pavement, road, sky, vegetation, and window.
Advancing Financial Risk Modeling: Vasicek Framework Enhanced by Agentic Generative AI

Publisher: name: figshare
Year: 2025
Subjects: classificationCode: 460201
subject: Artificial life and complex adaptive systems

description: ABSTRACTThis paper provides a comprehensive review of the Vasicek model and its applications in finance, categorizing the literature into four key areas: Vasicek model applications, Monte Carlo simulations, negative interest rates and risk, and deep learning for financial time series. To provide deeper insights, a synthesis chart and chronological analysis are included to highlight significant trends and contributions. Building upon this foundation, we employ Generative Adversarial Networks (GANs) and Variational Autoencoders (VAEs) to generate synthetic future interest rate data. These generated projections are then integrated as inputs into the Vasicek model, dynamically adjusting its parameters with the support of AI-driven synthetic data. Additionally, we propose the use of publicly available financial information, gathered via public-facing large language models (LLMs) like ChatGPT, to assess whether the models project trends in line with real-world data. Specifically, we will query ChatGPT to analyze 50 key questions related to interest rates, risk management strategies, inflation, and economic indicators from institutions like the Federal Reserve and banks. Our approach also leverages publicly available information to refine model outputs, reducing reliance on assumptions and emphasizing the alignment of AI-generated noise with observable market behaviors. By integrating these real-world insights, we aim to ensure that our models remain both innovative and grounded in current economic realities. Ultimately, this framework combines advanced generative AI models, such as GANs and VAEs, with human oversight and economic data, providing a robust, adaptable, and forward-thinking approach to financial risk modeling.

description: The modular multilevel converter offers benefits for medium and high voltage power conversion due to indirect series connection of devices. The drawback is a large amount of capacitance that has to be installed in each module, often prohibiting its use in cost sensitive applications. This letter proposes a new operation mode of modular multilevel topologies that allows reducing the capacitance by at least an order of magnitude. To achieve this, the multilevel operation is sacrificed, but many advantages of indirect series connection, such as proper voltage sharing, small voltage steps, limited voltage slopes, modularity, and scalability remain.

description: The General Antiparticle Spectrometer (GAPS) experiment is a novel approach for the detection of cosmic ray antiparticles. A prototype GAPS experiment (pGAPS) was successfully flown on a high-altitude balloon in June of 2012. The goals of the pGAPS experiment were: to test the operation of lithium drifted silicon (Si(Li)) detectors at balloon altitudes, to validate the thermal model and cooling concept needed for engineering of a full-size GAPS instrument, and to characterize cosmic ray and X-ray backgrounds. The instrument was launched from the Japan Aerospace Exploration Agency's (JAXA) Taiki Aerospace Research Field in Hokkaido, Japan. The flight lasted a total of 6 hours, with over 3 hours at float altitude (~33 km). Over one million cosmic ray triggers were recorded and all flight goals were met or exceeded.

description: Alors que la Russie de Vladimir Poutine se revendique volontiers d’un passé millénaire et que les tsars sont érigés en héros nationaux, la mémoire de 1917 apparaît comme étant de plus en plus difficile à assumer dans sa version soviétique, glorificatrice et manichéenne. Le récent centenaire, exempt en Russie de toute commémoration officielle, confirmerait ce constat. Cependant, les choix commémoratifs des autorités russes et des différents acteurs du champ mémoriel, ainsi que les points de vue de la population, perceptibles notamment à travers les sondages, semblent témoigner d’attitudes plus ambigües et paradoxales, combinant un rejet quasi-unanime de la révolution en tant que mode d’action politique, la persistance d’héritages mémoriels soviétiques et la recherche de nouvelles façons de mettre en récit la révolution.

description: The High-resolution Coronal Imager (Hi-C) has provided Fe XII 193A images of the upper transition region moss at an unprecedented spatial (~0.3-0.4 arcsec) and temporal (5.5s) resolution. The Hi-C observations show in some moss regions variability on timescales down to ~15s, significantly shorter than the minute scale variability typically found in previous observations of moss, therefore challenging the conclusion of moss being heated in a mostly steady manner. These rapid variability moss regions are located at the footpoints of bright hot coronal loops observed by SDO/AIA in the 94A channel, and by Hinode/XRT. The configuration of these loops is highly dynamic, and suggestive of slipping reconnection. We interpret these events as signatures of heating events associated with reconnection occurring in the overlying hot coronal loops, i.e., coronal nanoflares. We estimate the order of magnitude of the energy in these events to be of at least a few $10^{23}rg, also supporting the nanoflare scenario. These Hi-C observations suggest that future observations at comparable high spatial and temporal resolution, with more extensive temperature coverage are required to determine the exact characteristics of the heating mechanism(s).

description: The synthesis of deoxythymidine triphosphate (dTTP), as one of the four building blocks of DNA, plays a crucial role for the plant. Each cell compartment with its own sub genome therefore has a subset of enzymes necessary for the formation of thymidylates. However, the respective compartments are not purely self-sufficient systems, but are in constant exchange and can support each other depending on the developmental stage. Furthermore, the contribution of individual steps of thymidylate metabolism to the thymidylate pools varies in importance over time. According to current knowledge, the essential enzymes involved in the synthesis of dTTP in Arabidopsis thaliana are Dihydrofolate Reductase-Thymidilate Synthase (DHFR-TS), Thymidine Kinase (TK) and Deoxythymidine Monophosphate Kinase (TMPK, ZEU1). Complete loss of these enzymes is lethal for the plant, or in the case of TK, leads to a plant that can no longer reproduce. However, in the case of DHFR-TS and TK, only one of the two homologues is required for the development of a viable plant. This work shows that at germination, de novo biosynthesis, which proceeds via DHFR-TS, plays a minor role compared to salvage. However, the exclusively mitochondrial DHFR-TS2 isoenzyme appears to be more important than its cytosolic counterpart DHFR-TS1. A similar picture emerges for salvage. TK1b, present in chloroplasts and mitochondria, plays a more important role than its cytosolic representative TK1a. Particularly the chloroplastic TK1b has a greater impact in supplying the cell with thymidylates, which coincides with the synthesis of cpDNA being also the greatest sink during this time. A TK1b mutant shows a severe arrest in cpDNA synthesis during germination. The synthesis of cpDNA is partially restored in the established seedling and thymidylate pools are then also affected in a mutant lacking cytosolic TK1a suggesting that the supply of thymidylates is then secured by both cytosolic and organellar salvage. Among the less important enzymes, appear to be dUTP Pyrophosphatase 1 localized in chloroplasts and mitochondria (DUT1org) and dCMP Deaminase (DCD) localized in mitochondria. Both enzymes play a minor role in providing dUMP for DHFR-TS. In neither of the two associated mutants a serious disruption of thymidylate formation is observable. This may be due to an involvement of both enzymes in the formation of dUMP, as indicated by preliminary data suggesting that a DCD DUT1org mutant is not viable.

description: We investigate the ${\cal O}(α_s)$ correction to $e^+e^-\to J/ψ+η_{c2}$ in the NRQCD factorization approach. A detailed comparative study between $e^+e^-\to J/ψ+η_{c2}$ and $e^+e^-\to J/ψ+χ^\prime_{c1}$ at $B$ factory energy is also carried out. After incorporating the ${\cal O}(α_s)$ correction, we predict the cross section for the former process to be around 0.3 fb, while that of the latter about 6 times greater. The outgoing $J/ψ$ is found to be dominantly transversely-polarized in the former process, while longitudinally-polarized in the latter. These features may provide valuable guidance for the future experiment to examine the ${}^3P_1$ or ${}^1D_2$ charmonium option of the X(3872) meson through the exclusive double-charmonium production processes. The observation potential of $e^+e^-\to J/ψ+χ^\prime_{c1}$ looks bright for the current data sample of the \textsc{Belle} experiment, provided that the $χ^\prime_{c1}$ is indeed the narrow X(3872) state. In the appendix, we also identify the coefficients of the double logarithms of form $\ln^2(s/m_c^2)$ associated with all the relevant next-to-leading order Feynman diagrams, for the helicity-suppressed double-charmonium production channels $e^+ e^- \to J/ψ+ η_{c2}(η_c,χ_{c0,1,2})$.

description: Genetic analysis was carried out in order to provide insights into differentiation among populations of two interfertile oak species, Quercus petraea and Quercus robur. Gene flow between the two species, local adaptations and speciation processes in general, may leave differential molecular signatures across the genome. Three interspecific pairs of natural populations from three ecologically different regions, one in central Europe (SW Germany) and two in the Balkan Peninsula (Greece and Bulgaria) were sampled. Grouping of highly informative SSR loci was made according to the component of variation they express - interspecific or provenance specific. Species and provenance discriminant loci were characterized based on FSTs. Locus specific FSTs were tested for deviation from the neutral expectation both within and between species. Data were then treated separately in a Bayesian analysis of genetic structure. By using three species discriminant loci, high membership probability to inferred species groups was achieved. On the other hand, analysis of genetic structure based on five provenance discriminant loci was correlated with geographic region and revealed shared genetic variation between neighbouring Q. petraea and Q. robur. Small sets of highly variable nuclear SSRs were sufficient to discriminate, either between species or between provenances. Thus, an effective tool is provided for molecular identification of both species and provenances. Furthermore, data suggest that a combination of gene flow and natural selection forms these diversity patterns. Species discriminant loci might represent genome regions affected by directional selection, which maintains species identity. Provenance specific loci might represent genome regions with high interspecific gene flow and common adaptive patterns to local environmental factors.

Universal damping behavior of dipole oscillations of one-dimensional ultracold gases induced by quantum phase slips

description: We study superflow decay via quantum phase slips in trapped one-dimensional (1D) quantum gases through dipole oscillations induced by sudden displacement of the trapping potential. We find the relation between the damping rate of the dipole oscillation $G$ and the phase-slip nucleation rate $Γ$ as $G\propto Γ/v$, where $v$ is the flow velocity. This relation allows us to show that damping of 1D Bose gases in optical lattices, which has been extensively studied in experiment, is due to quantum phase slips. It is also found that the damping rate versus the flow velocity obeys the scaling formula for an impurity potential even in the absence of an explicit impurity. We suggest that the damping rate at a finite temperature exhibits a universal crossover behavior upon changing the flow velocity.

description: One way of enhancing and broadening resistance of plants to different biotic and abiotic stresses is to combine transgenes expressing several genes into a single line. This can be done using different strategies such as crossing, single vector with multiple genes, co-transformation, sequential transformation and IRES elements. In the present study conventional crossing method was used. Parental transgenic lines transformed via Agrobacterium tumefasciens-mediated gene transformation with pGreenII binary vector harbouring a bar gene as selectable marker in combination with the family 19 chitinase gene from Streptomyces olivaceoviridis for one line and 1,3-β-glucanase from barley (Hordeum vulgare) for the other line were used for crossing. Both chitinase and glucanase genes were cloned into pGreenII vector under the control of the constitutive double 35S-promoter from cauliflower mosaic virus. Progenies expressing the two genes were characterised at the molecular level using PCR, RT-PCR and Southern blot analysis, as well as segregation and stability studies of the respective expression levels. Leaf paint assay was used as functional test for herbicide resistant gene. Stable inheritance of the antifungal genes in the transgenic plants was demonstrated. The synergistic effect of crossed plants was tested using in vitro assay which shows higher inhibition of spore germination.

description: Ab initio simulations are combined with in situ infrared spectroscopy to unveil the molecular transport of H$_2$, CO$_2$, and H$_2$O in the metal organic framework MOF-74-Mg. Our study uncovers---at the atomistic level---the major factors governing the transport mechanism of these small molecules. In particular, we identify four key diffusion mechanisms and calculate the corresponding diffusion barriers, which are nicely confirmed by time-resolved infrared experiments. We also answer a long-standing question about the existence of secondary adsorption sites for the guest molecules, and we show how those sites affect the macroscopic diffusion properties. Our findings are important to gain a fundamental understanding of the diffusion processes in these nano-porous materials, with direct implications for the usability of MOFs in gas sequestration and storage applications.

description: We aim to study the spatial distribution of the physical and chemical properties of the X-ray emitting plasma of the supernova remnant G272.2-3.2, in order to get important constraints on its ionization stage, on the progenitor supernova explosion, and the age of the remnant. We report combined XMM-Newton and Chandra images, median photon energy map, silicon and sulfur equivalent width maps, and a spatially resolved spectral analysis for a set of regions of the remnant. Complementary radio and Hα observations, available in the literature, are also used to study the multi-wavelength connection of all detected emissions. The X-ray morphology of the remnant displays an overall structure with an almost circular appearance, a centrally brightened hard region, with a peculiar elongated hard structure oriented along the northwest-southeast direction of the central part. The X-ray spectral study of the regions shows distinct Kα emission-line features of metal elements, confirming the thermal origin of the emission. The X-ray spectra are well represented by an absorbed VNEI thermal plasma model, which produces elevated abundances of Si, S, and Fe in the circular central region, typical of ejecta material. The values of abundances found in the central region of the SNR favor a Type Ia progenitor for this remnant. The outer region shows abundances below the solar value, as expected if the emission arises from the shocked ISM. The relatively low ionization timescales suggests non-equilibrium ionization. We identify the location of the contact discontinuity. Its distance to the outer shock is higher than expected for expansion in a uniform media, what suggests that the remnant spent most of its time in a more dense medium.

description: Disassembly is a crucial step towards sustainable life cycle engineering. During the operation, assembly connections solidify to an unknown state, e.g. due to thermal or mechanical stress on the product. Therefore, disassembly forces are hard to predict. With regard to automated disassembly, this complicates the proper planning of disassembly times and tools. The uncertainties can lead to damage or destruction of the product, impeding regeneration. To tackle these problems, in earlier work, we proposed a solidification model, which enables planners to predict disassembly forces based on the products geometric properties and operational history without investigating the complex physical influences caused by the usage of the product. The disassembly of high-value capital goods like aircraft engines, in particular blade-disk connections, serves as an application case. Still, we were not yet able to validate the solidification model due to the lack of experimental reproducibility. In this work, we adapt the existing model of a solidified assembly connection created in prior work with an additional clamping force. The additional force aims to represent the solidification force. This can significantly increase reproducibility and reduce disturbances.

Proper formulation of viscous dissipation for nonlinear waves in solids

description: In order to model nonlinear viscous dissipative motions in solids, acoustical physicists usually add terms linear in dot{E}, the material time derivative of the Lagrangian strain tensor E, to the elastic stress tensor sigma derived from the expansion to the third- (sometimes fourth-) order of the strain energy density e=e(trace(E), trace(E^2), trace(E^3)). Here, it is shown that this practice, which has been widely used in the past three decades or so, is physically wrong for at least two reasons, and that it should be corrected. One reason is that the elastic stress tensor sigma is not symmetric while dot{E) is symmetric, so that motions for which sigma + sigma^T <> 0 will give rise to elastic stresses which have no viscous pendant. Another reason is that dot{E} is frame-invariant, while sigma is not, so that an observer transformation would alter the elastic part of the total stress differently than it would alter the dissipative part, thereby violating the fundamental principle of material frame-indifference. These problems can have serious consequences for nonlinear shear wave propagation in soft solids, as seen here with an example of a kink in almost incompressible soft solids.
