    Word Sense Change Testset
    2017-07-21
    Tahmasebi, Nina
    Risse, Thomas orcid-logo
    This testset consists of 23 terms which have experienced word sense change during the past centuries. The main changes for each term were found using Wikipedia, dictionary.com and the Oxford English Dictionary. We consider major changes in usage as well as changes to sense. In cases where multiple (fine-grained) senses were available, we opted to accept the widest sense. E.g. for the term rock we consider a music sense without any distinction between different types of rock music, because our dataset is unlikely to have fine-grained sense differentiations. If a clear time point cannot be pinpointed, we choose the earliest possible. For comparison purposes we also chose a set of 11 terms that have experienced minimal change during the investigated period, i.e., stable terms.

    Theoretical data for: Orbital occupancy and hybridization in strained SrVO3 epitaxial films
    2021-09-09
    Valadkhani, Adrian 
    These data were produced for an experimental paper of M. Mirjolet [1]. To generate them we used the density functional theory FPLO [2]. This gave us the integrated density of states, with whom we combined the different orbitals and atoms to obtain the results depicted in the publication [1]. The data of the post processing part are the data given in this upload. To reproduce the density functional part one needs to repeat the calculation. The input parameters are given in the publication [1]. For further information on the experimental data, please contact: mathieu.mirjolet@gmail.com. [1] M. Mirjolet et al. Phys. Rev.

    Epitaxial EuPd2Si2 thin films
    2022-11
    Kölsch, Sebastian 
    Bulk EuPd2Si2 show a temperature-driven valence transisition of europium from ~+2 above 200 K to~+3 below 100 K, which is correlated with a shrinking by approximatly 2 % of the crystal lattice along the two a-axes. Due to this interconnection between lattice and electronic degrees of freedom the influence of strain in epitaxial thin films is particularly interesting. Ambient X-ray diffraction (XRD) confirms an epitaxial relationship of tetragonal EuPd2Si2 on MgO(001) with an out-of plane c-axis orientation for the thin film, whereby the a-axes of both lattices align. XRD at low temperatures reveals a strong coupling of the thin film lattice to the substrate, showing no abrupt compression over the temperature range from 300 to 10 K. Hard X-ray photoelectron spectroscopy at 300 and 20 K reveals a temperature-independent valence of +2.0 for Eu. The evolving biaxial tensile strain upon cooling is suggested to suppress the valence transition. Instead low temperature transport measurements of the resistivity and the Hall effect in a magnetic field up to 5 T point to a film thickness independent phase transition at 16-20 K, indicating magnetic ordering.

    Section-Type Constraints on the Choice of Linguistic Mechanisms in Research Articles: A Corpus-Based Approach
    2023
    Ivanova, Iverina orcid-logo
    This thesis investigates the structure of research articles in the field of Computational Linguistics with the goal of establishing that a set of distinctive linguistic features is associated with each section type. The empirical results of the study are derived from the quantitative and qualitative evaluation of research articles from the ACL Anthology Corpus. More than 20,000 articles were analyzed for the purpose of retrieving the target section types and extracting the predefined set of linguistic features from them. Approximately 1,100 articles were found to contain all of the following five section types: abstract, introduction, related work, discussion, and conclusion. These were chosen for the purpose of comparing the frequency of occurrence of the linguistic features across the section types. Making use of frameworks for Natural Language Processing, the Stanford CoreNLP Module, and the Python library SpaCy, as well as scripts created by the author, the frequency scores of the features were retrieved and analyzed with state-of-the-art statistical techniques. The results show that each section type possesses an individual profile of linguistic features which are associated with it more or less strongly. These section-feature associations are shown to be derivable from the hypothesized purpose of each section type. Overall, the findings reported in this thesis provide insights into the writing strategies that authors employ so that the overall goal of the research paper is achieved. The results of the thesis can find implementation in new state-of-the-art applications that assist academic writing and its evaluation in a way that provides the user with a more sophisticated, empirically based feedback on the relationship between linguistic mechanisms and text type. In addition, the potential of the identification of text-type specific linguistic characteristics (a text-feature mapping) can contribute to the development of more robust language-based models for disinformation detection.

    Microscopic analysis of the valence transition in tetragonal EuPd2Si2
    2023-02-23
    Song, Young-Joon 
    Under temperature or pressure tuning, tetragonal EuPd2Si2 is known to undergo a valence transition from nearly divalent to nearly trivalent Eu accompanied by a volume reduction. Albeit intensive work, its microscopic origin is still being discussed. Here, we investigate the mechanism of the valence transition under volume compression by ab initio density functional theory (DFT) calculations. Our analysis of the electronic and magnetic properties of EuPd2Si2 when approaching the valence transition shows an enhanced c−f hybridization between localized Eu 4f states and itinerant conduction states (Eu 5d, Pd 4d, and Si 3p) where an electronic charge redistribution takes place. We observe that the change in the electronic structure is intimately related to the volume reduction where Eu-Pd(Si) bond lengths shorten and, for the transition to happen, we trace the delicate balance between electronic bandwidth, crystal field splitting, Coulomb repulsion, Hund's coupling and spin-orbit coupling. In a next step we compare and benchmark our DFT results to surface-sensitive photoemission data in which the mixed-valent properties of EuPd2Si2 are reflected in a simultaneous observation of divalent and trivalent signals from the Eu 4f shell. The study serves as well to explore the limits of density functional theory and the choice of exchange correlation functionals to describe such a phenomenon as a valence transition.

    A j_eff 12 Kitaev material on the triangular lattice: The case of NaRuO2
    2023-06-07
    Razpopov, Aleksandar orcid-logo
    Motivated by recent reports of a quantum disordered ground state in the triangular lattice compound NaRuO$_2$, we derive a $j_{\rm eff}=1/2$ magnetic model for this system by means of first-principles calculations. The pseudospin Hamiltonian is dominated by bond-dependent off-diagonal $\Gamma$ interactions, complemented by a ferromagnetic Heisenberg exchange and a notably \emph{antiferromagnetic} Kitaev term. In addition to bilinear interactions, we find a sizable four-spin ring exchange contribution with a \emph{strongly anisotropic} character, which has been so far overlooked when modeling Kitaev materials. The analysis of the magnetic model, based on the minimization of the classical energy and exact diagonalization of the quantum Hamiltonian, points toward the existence of a rather robust easy-plane ferromagnetic order, which cannot be easily destabilized by physically relevant perturbations.

    From valence fluctuations to long-range magnetic order in EuPd2(Si1−xGex)2 single crystals, original data from the figuresPaper
    2023-06-12
    Krellner, Cornelius 
    EuPd2Si2 is a valence-fluctuating system undergoing a temperature-induced valence crossover at T_V=160 K. We present the successful single-crystal growth using the Czochralski method for the substitution series EuPd2(Si1−xGex)2, with substitution levels x < 0.15. A careful determination of the germanium content revealed that only half of the nominal concentration is built into the crystal structure. From thermodynamic measurements it is established that T_V is strongly suppressed for small substitution levels and antiferromagnetic order from stable divalent europium emerges for x ~ 0.10. The valence transition is accompanied by a pronounced change of the lattice parameter a of order 1.8%. In the antiferromagnetically ordered state below T_N = 47 K, we find sizable magnetic anisotropy with an easy plane perpendicular to the crystallographic c direction. An entropy analysis revealed that no valence fluctuations are present for the magnetically ordered materials. Combining the obtained thermodynamic and structural data, we construct a concentration-temperature phase diagram demonstrating a rather abrupt change from a valence-fluctuating to a magnetically ordered state in EuPd2(Si1−xGex)2.

    Field-induced effects in the spin liquid candidate PbCuTe2O6
    2023-06-16
    Tutsch, Ulrich 
    PbCuTe2O6 is considered to be one of the rare candidate materials for a three-dimensional quantum spin liquid (QSL). This assessment was based on the results of various magnetic experiments, performed mainly on polycrystalline material. More recent measurements on single crystals revealed an even more exotic behavior, yielding ferroelectric order below T_FE ≈ 1 K, accompanied by distinct lattice distortions, and a somewhat modified magnetic response which is still consistent with a QSL. Here we report on low-temperature measurements of various thermodynamic, magnetic, and dielectric properties of single-crystalline PbCuTe2O6 in magnetic fields B ≤ 14.5 T. The combination of these various probes allows us to construct a detailed B-T phase diagram including a ferroelectric phase for B ≤ 8 T and a B-induced magnetic phase at B ≥ 11 T. These phases are preceded by or coincide with a structural transition from a cubic high-temperature phase into a distorted noncubic low-temperature state. The phase diagram discloses a ferroelectric quantum critical point at B_c1 = 7.9 T, where the second-order phase transition line associated with ferroelectric order is suppressed to zero. In addition, a magnetic quantum phase transition is revealed at B_c2 = 11 T. The corresponding phase transition to a fieldinduced magnetic order at B > B_c2 is likely to be of first order. Field-induced lattice distortions, observed in the state at T > 1 K and which are assigned to the effect of spin-orbit interaction of the Cu2+ ions, are considered as the key mechanism by which the magnetic field couples to the dielectric degrees of freedom in this material.

    From magnetic order to valence-change crossover in EuPd2(Si1−xGex)2 using He-gas pressure
    2023-06-19
    Tutsch, Ulrich 
    We present results of magnetic susceptibility and thermal expansion measurements performed on high-quality single crystals of EuPd2(Si1−xGex )2 for 0 ≤ x ≤ 0.2 and temperatures 2 K ≤ T ≤ 300 K. Data were taken at ambient pressure and finite He-gas pressure p ≤ 0.5 GPa. For x = 0 and ambient pressure we observe a pronounced valence-change crossover centred around T′_V ≈ 160 K with a non-magnetic ground state. This valence-change crossover is characterized by an extraordinarily strong pressure dependence of dT′_V /dp = (80 ±10) K/GPa. We observe a shift of T′_V to lower temperatures with increasing Ge-concentration, reaching T′_V ≈ 90 K for x = 0.1, while still showing a non-magnetic ground state. Remarkably, on further increasing x to 0.2 we find a stable Eu(2+δ)+ valence with long-range antiferromagnetic order below T_N = (47.5 ± 0.1) K, reflecting a close competition between two energy scales in this system. In fact, by the application of hydrostatic pressure as small as 0.1 GPa, the ground state of this system can be changed from long-range antiferromagnetic order for p < 0.1 GPa to an intermediate-valence state for p ≥ 0.1 GPa.

    Pressure study on the interplay between magnetic order and valence crossover in EuPd2(Si1−xGex)2
    2023-06-30
    Tutsch, Ulrich 
    We present results of the magnetic susceptibility on high-quality single crystals of EuPd2(Si1−xGex )2 for Ge concentrations 0 ≤ x ≤ 0.105 performed under varying hydrostatic (He-gas) pressure 0 ≤ p ≤ 0.5 GPa. The work extends recent studies at ambient pressure demonstrating the drastic change in the magnetic response from valence-crossover behavior for x = 0 and 0.058, to long-range antiferromagnetic (AFM) order below T_N = 47 K for x = 0.105. The valence-crossover temperature T_V shows an extraordinarily strong pressure dependence of dT'_V/dp= +(80 ± 10) K/GPa. In contrast, a very small pressure dependence of dT_N/dp ≤ +(1 ± 0.5) K/GPa is found for the AFM order upon pressurizing the x = 0.105 crystal from p = 0 to 0.05 GPa. Remarkably, by further increasing the pressure to 0.1 GPa, a drastic change in the ground state from AFM order to valencecrossover behavior is observed. Estimates of the electronic entropy related to the Eu 4f electrons, derived from analyzing susceptibility data at varying pressures, indicate that the boundary between AFM order and valence crossover represents a first-order phase transition. Our results suggest a particular type of second-order critical end point of the first-order transition for x = 0.105 at p_cr ≈ 0.06 GPa and T_cr ≈ 39 K where intriguing strong-coupling effects between fluctuating charge, spin, and lattice degrees of freedom can be expected.

    Colossal magnetoresistance in EuZn2P2 and its electronic and magnetic structure
    2023-07-12
    Krebber, Sarah 
    We investigate single crystals of the trigonal antiferromagnet EuZn2P2 (P-3m1) by means of electrical trans- port, magnetization measurements, x-ray magnetic scattering, optical reflectivity, angle-resolved photoemission spectroscopy (ARPES), and ab initio band structure calculations (DFT + U ). We find that the electrical resistivity of EuZn2P2 increases strongly upon cooling and can be suppressed in magnetic fields by several orders of magnitude (colossal magnetoresistance effect). Resonant magnetic scattering reveals a magnetic ordering vector of q = (0 0 1/2 ), corresponding to an A-type antiferromagnetic order, below TN = 23.7 K. We find that the moments are canted out of the a-a plane by an angle of about 40° ± 10° and aligned along the [100] direction in the a-a plane. We observe nearly isotropic magnetization behavior for low fields and low temperatures which is consistent with the magnetic scattering results. The magnetization measurements show a deviation from the Curie-Weiss behavior below ≈150 K, the temperature below which also the field dependence of the material’s resistivity starts to increase. An analysis of the infrared reflectivity spectrum at T = 295 K allows us to resolve the main phonon bands and intraband and interband transitions, and estimate indirect and direct band gaps of E_opt,i = 0.09 and E_opt,d = 0.33 eV, respectively, which are in good agreement with the theoretically predicted ones. The experimental band structure obtained by ARPES is nearly T independent above and below T_N . The comparison of the theoretical and experimental data shows a weak intermixing of the Eu 4f states close to the point with the bands formed by the phosphorous 3p orbitals leading to an induction of a small magnetic moment at the P sites.

    The Al-Mudhaybi Regional Survey was initiated to gain insights into settlement patterns, their development, and the causes of significant social changes in Central Oman, particularly during the 3rd millennium BCE. This was achieved through a combination of survey methods (remote sensing based on satellite imagery with ground-truthing and intensive systematic surveys in north-south transects) as well as small-scale excavations. The results challenged the previous notion of traditional settlement hierarchies and a predominantly sedentary, agriculture-based society in Central Oman, especially during the Early Bronze Age (Umm an-Nar period). In-stead, a complex network of temporary sites emerged, utilized at various times and for different activities. Another significant finding is that the interior of Oman was more heavily frequented during the Neolithic period than previously believed. Additionally, contrary to prior assumptions, the Middle Bronze Age (Wadi Suq period) does not represent a period of decline and shares similarities in its development with the northern regions of the Omani Peninsula. These findings can contribute to raising awareness of the diversity of human lifestyles overall, particularly highlighting the cultural achievements of mobile communities.

    Assessing global freshwater resources and human water use is of value for a number of needs but challenging. The global water use and water availability model WaterGAP has been in development since 1996 and has served a range of applications such as assessments of global water resources and water stress, also under the impact of climate change, drought hazard quantification, Life Cycle Assessments, water (over)use and consequently depletion of water resources and a better understanding of terrestrial water storage variations (jointly with satellite observations). Here, the reader can download model output for the time period 1901-2019 that was computed by driving WaterGAP v2.2e by four alternative climate datasets (climate forcings) that were generated in the ISIMIP context (https://www.isimip.org) and are described in https://data.isimip.org/10.48364/ISIMIP.982724. For two climate datasets, model runs up to 2021 or 2022 are available. For comparison, output of a version of WaterGAP v2.2d that is calibrated to the same dataset of observed streamflow as WaterGAP v2.2e is provided. Each of the climate forcing-model version combinations is run in two socio-economic settings, histsoc and nosoc. In nosoc, human water use is set to zero and man-made reservoirs are assumed to be non-existant. In the paper connected to this dataset (to be submitted to Geoscientific Model Development), the newest model version, WaterGAP v2.2e is described by providing the modifications to the previous version v2.2d (Müller Schmied et al. 2021) and the corresponding changes in model output. The most important and requested model outputs (total water storage variations, streamflow and water use) are evaluated against observation data. Standard model output is described as well as the specifics of the WaterGAP contribution within the ISIMIP framework.

    Assessing global freshwater resources and human water use is of value for a number of needs but challenging. The global water use and water availability model WaterGAP has been in development since 1996 and has served a range of applications such as assessments of global water resources and water stress, also under the impact of climate change, drought hazard quantification, Life Cycle Assessments, water (over)use and consequently depletion of water resources and a better understanding of terrestrial water storage variations (jointly with satellite observations). Here, the reader can download model output for the time period 1901-2019 that was computed by driving WaterGAP v2.2e by four alternative climate datasets (climate forcings) that were generated in the ISIMIP context (https://www.isimip.org) and are described in https://data.isimip.org/10.48364/ISIMIP.982724. For two climate datasets, model runs up to 2021 or 2023 are available. For comparison, output of a version of WaterGAP v2.2d that is calibrated to the same dataset of observed streamflow as WaterGAP v2.2e is provided. Each of the climate forcing-model version combinations is run in two socio-economic settings, histsoc and nosoc. In nosoc, human water use is set to zero and man-made reservoirs are assumed to be non-existant. In the paper connected to this dataset (in review with Geoscientific Model Development), the newest model version, WaterGAP v2.2e is described by providing the modifications to the previous version v2.2d (Müller Schmied et al. 2021) and the corresponding changes in model output. The most important and requested model outputs (total water storage variations, streamflow and water use) are evaluated against observation data. Standard model output is described as well as the specifics of the WaterGAP contribution within the ISIMIP framework.
