description: In arXiv:1306.2117, we found explicit Lax pairs for the soft edge of beta ensembles with even integer values of $β$. Using this general result, the case $β=6$ is further considered here. This is the smallest even $β$, when the corresponding Lax pair and its relation to Painlevé II (PII) have not been known before, unlike cases $β=2$ and $4$. It turns out that again everything can be expressed in terms of the Hastings-McLeod solution of PII. In particular, a second order nonlinear ODE for the logarithmic derivative of Tracy-Widom distribution for $β=6$ involving the PII function in the coefficients, is found, which allows one to compute asymptotics for the distribution function. The ODE is a consequence of a linear system of three ODEs for which the local singularity analysis yields series solutions with exponents in the set $4/3$, $1/3$ and $-2/3$.

description: Recently, automatic classification of IT tickets has gained notable attention due to the increasing complexity of IT services deployed in enterprises. There are multiple discussions and no general opinion in the research and practitioners' community on the design of IT ticket classification tasks, specifically the choice of ticket text representation techniques and classification algorithms. Our study aims to investigate the core design elements of a typical IT ticket text classification pipeline. In particular, we compare the performance of TF-IDF and linguistic features-based text representations designed for ticket complexity prediction. We apply various classifiers, including kNN, its enhanced versions, decision trees, naïve Bayes, logistic regression, support vector machines, as well as semi-supervised techniques to predict the ticket class label of low, medium, or high complexity. Finally, we discuss the evaluation results and their practical implications. As our study shows, linguistic representation not only proves to be highly explainable but also demonstrates a substantial prediction quality increase over TF-IDF. Furthermore, our experiments evidence the importance of feature selection. We indicate that even simple algorithms can deliver high-quality prediction when using appropriate linguistic features.

description: Radio-frequency (RF) impairments in the transceiver hardware of communication systems (e.g., phase noise (PN), high power amplifier (HPA) nonlinearities, or in-phase/quadrature-phase (I/Q) imbalance) can severely degrade the performance of traditional multiple-input multiple-output (MIMO) systems. Although calibration algorithms can partially compensate these impairments, the remaining distortion still has substantial impact. Despite this, most prior works have not analyzed this type of distortion. In this paper, we investigate the impact of residual transceiver hardware impairments on the MIMO system performance. In particular, we consider a transceiver impairment model, which has been experimentally validated, and derive analytical ergodic capacity expressions for both exact and high signal-to-noise ratios (SNRs). We demonstrate that the capacity saturates in the high-SNR regime, thereby creating a finite capacity ceiling. We also present a linear approximation for the ergodic capacity in the low-SNR regime, and show that impairments have only a second-order impact on the capacity. Furthermore, we analyze the effect of transceiver impairments on large-scale MIMO systems; interestingly, we prove that if one increases the number of antennas at one side only, the capacity behaves similar to the finite-dimensional case. On the contrary, if the number of antennas on both sides increases with a fixed ratio, the capacity ceiling vanishes; thus, impairments cause only a bounded offset in the capacity compared to the ideal transceiver hardware case.

title: Fernunterricht im Dolmetschen am ZTW im Sommersemester 2020 aus Studierendensicht
Creators: name: Clauberg, Theresa
Year: 2022

description: Im März 2020 erforderte die Coronapandemie eine spontane Umstellung der universitären Lehre auf Fernlehre. Das Studium am Zentrum für Translationswissenschaft (ZTW) wurde not- gedrungen in den Cyberspace verschoben. Wie die Studierenden des MA Translation am ZTW diese Umstellung und das Sommersemester 2020 erlebten, wurde im Rahmen der vorliegenden Arbeit untersucht. Auf einer qualitativen Interviewvorstudie basierend, wurde eine quantitative Onlinebefragung erstellt, welche von Studierenden der Schwerpunkte Konferenz- und Dialog- dolmetschen im MA Translation beantwortet wurden. Im Rahmen der Arbeit werden die Um- stände, welche zur Fernlehre führten und die Entwicklung der Coronapandemie in Österreich beschrieben. Es folgt ein Einblick in die Dialogdolmetschlehre in Präsenz und im Fernlehrfor- mat und in das Studium am ZTW vor der Coronapandemie. Anschließend wird das methodische Vorgehen der Onlinebefragung beschrieben und die Interviewvorstudie vorgestellt. Im An- schluss folgt die Ergebnisanalyse der Onlinebefragung und eine Diskussion der Ergebnisse. Die Auswertung zeigt eindeutig, dass die Studierenden mit der Umstellung auf Fernlehre gut zu- rechtkamen und sie sich gewisse Aspekte der Fernlehre sogar in Zukunft als festen Bestandteil des Studiums am ZTW vorstellen können.
description: In March 2020, the corona pandemic forced a spontaneous conversion of university teaching to distance learning. Studies at the Center for Translation Studies at the University of Vienna (ZTW) had to be shifted into cyberspace. How the students of the MA Translation at the ZTW experienced this change and the summer semester 2020 was investigated in this paper. Based on a qualitative interview pre-study, a quantitative online survey was created, which was an- swered by students majoring in conference and dialogue interpreting in the study program MA Translation. This paper describes the circumstances that led to distance learning and the devel- opment of the corona pandemic in Austria. This is followed by an insight into the teaching of dialogue interpreting in presence and distance learning formats and into the studies at the ZTW before the corona pandemic. Then the methodological procedure of the online survey is de- scribed and the interview pre-study is presented. This is followed by an analysis of the results of the online survey and a discussion of the results. The survey results clearly show that the students coped well with the change to distance learning and that they can even imagine certain aspects of distance learning as a permanent part of their studies at the ZTW in the future.

description: In this study, we aimed to explore the rural landscape transformation through the analysis of land use/land cover (LULC) spatio-temporal dynamics in the entire Vietnamese Mekong Delta over the three decades, using Landsat imageries and a supervised random forest classifier. Results indicated that in the 1990s, dominant LULC types were arable cropland, wetland, and permanent crops, which covered approximately half of the delta, 28% and 8%, respectively. From 1990 to 2019, the wetland area decreased from 28% to 5% due to the expansion of aquaculture and the arable cropland. The aquaculture, however, expanded more rapidly than other land use conversions, namely, from 2% to 19%. Although mangrove forests slightly recovered by 58 km2 from 2005 to 2019, the overall trend (1990-2019) showed an intense loss of 740 km2 due to widespread conversions into aquaculture. The paper unravels the complex dynamics between land-cover change, socio-economic development and associated land-use policies, which have significant implications for the change in rural landscapes.
The inner regions of protoplanetary disks: a dynamical perspective
Creators: name: Facchini, Stefano
Publisher: name: Zenodo
Year: 2018

description: The high abundance of planets orbiting within 1 au from the central star, near the silicate sublimation front, poses many questions about their origin. An observational and theoretical characterisation of the inner disk (<1 au) is needed. Relatively simple hydrostatic equilibrium models have been successful in reproducing many observational constraints of the inner rim. Radiation hydrodynamics simulations are now showing that these models are hydrodynamically stable. Magneto-hydrodynamical effects are also important in the very inner regions, where the high ionisation fraction couples gas motions with the magnetic field. MHD effects reproduce observed variability in the NIR, and can generate a local pressure maximum at ~ 1 au scale where radially drifting pebbles can accumulate. Magnetic torques can also induce warps, casting an asymmetric shadow onto the outer regions of the disk. A similar dynamical effect can be induced by companions breaking the inner disk, and disconnecting its precession from the outer regions.

description: In this paper we show that the vanishing of the scalar curvature of Ruppeiner-like metrics does not characterize the ideal gas. Furthermore, we claim through an example that flatness is not a sufficient condition to establish the absence of interactions in the underlying microscopic model of a thermodynamic system, which poses a limitation on the usefulness of Ruppeiner's metric and conjecture. Finally, we address the problem of the choice of coordinates in black hole thermodynamics. We propose an alternative energy representation for Kerr-Newman black holes that mimics fully Weinhold's approach. The corresponding Ruppeiner's metrics become degenerate only at absolute zero and have non-vanishing scalar curvatures.

We illustrated the formulation within the Kane-Mele model of graphene in the absence and in the presence of the Rashba spin-orbit coupling term.

description: With the advent of digital transformation, organizations increasingly rely on various information systems to support their business processes (BPs). Recorded data, including textual data and event log, expand exponentially, complicating decision-making and posing new challenges for BP complexity analysis in Business Process Management (BPM). Herein, Process Mining (PM) serves to derive insights based on historic BP execution data, called event log. However, in PM, textual data is often neglected or limited to BP descriptions. Therefore, in this study, we propose a novel approach for analyzing BP execution complexity by combining textual data serving as an input at the BP start and event log. The approach is aimed at studying the connection between complexities obtained from these two data types. For textual data-based complexity, the approach employs a set of linguistic features. In our previous work, we have explored the design of linguistic features favorable for BP execution complexity prediction. Accordingly, we adapt and incorporate them into the proposed approach. Using these features, various machine learning techniques are applied to predict textual data-based complexity. Moreover, in this prediction, we show the adequacy of our linguistic features, which outperformed the linguistic features of a widely-used text analysis technique. To calculate event log-based complexity, the event log and relevant complexity metrics are used. Afterward, a correlation analysis of two complexities and an analysis of the significant differences in correlations are performed. The results serve to derive recommendations and insights for BP improvement. We apply the approach in the IT ticket handling process of the IT department of an academic institution. Our findings show that the suggested approach enables a comprehensive identification of BP redesign and improvement opportunities.

Observations of outflows and angular momentum transport from the inner to the outer disk
Creators: name: García López, Rebeca
Publisher: name: Zenodo
Year: 2018

description: Viscous disks have been at the base of our current understanding of angular momentum transport and disk accretion. However, new theoretical studies predict that turbulence might not be efficient enough to carry angular momentum in the inner layers of circumstellar disks within 0.5 to 10 au from the source. Instead, strong MHD disk winds are thought to be launched in this central region, carrying away the excess angular momentum in a very efficient way. Recently, IR interferometers have begun to resolve the inner disk regions of protoplanetary disks. These studies surprisingly reveal the presence of wind emission in the innermost regions of disks, within a few stellar radii from the source, and thus indicate that MHD winds might play a major role in the removal of angular momentum. A new generation of much powerful interferometric instruments, more sensitive and with improved imaging capabilities is now coming on stream. In this talk, I will review the latest findings in the field of high angular resolution observations of protoplanetary disks, and how these studies can help us to constrain the inner disk structure and evolution.

description: There is a significant impact of climate change on species distribution and vegetation patterns in high mountain regions, which is a major topic of research in biogeography. It has recently warmed up on the Western Sichuan Plateau, one of the most vulnerable regions to climate change. Based on the MaxEnt model, we were able to predict distributions based on current and future climate conditions, and determine the trend of distribution change and the underlying climate factors. Under current climate conditions, the two typical tree species display distinct spatial distributions. Furthermore, under future climate conditions, distribution ranges of both typical tree species will shrink and move to the northern part of the plateau. The variation in temperature between seasons and years affected the distribution of two tree species. This study provided a scientific basis for understanding how high mountain and plateau forests respond to climate change.

description: We report on the investigation of a superconducting anharmonic multi-level circuit that is coupled to a harmonic readout resonator. We observe multi-photon transitions via virtual energy levels of our system up to the fifth excited state. The back-action of these higher-order excitations on our readout device is analyzed quantitatively and demonstrated to be in accordance with theoretical expectation. By applying a strong microwave drive we achieve multi-photon dressing within our anharmonic circuit which is dynamically coupled by a weak probe tone. The emerging higher-order Rabi sidebands and associated Autler-Townes splittings involving up to five levels of the investigated anharmonic circuit are observed. Experimental results are in good agreement with master equation simulations.

description: Indian Space Research Organisation (ISRO) launched SCATSAT-1 scatterometer, on 26 September 2016 as a continuation and enhancement of OSCAT onboard OceanSat-2. The present work carries out a detailed inter-comparison of swath-wise level 2B data from SCATSAT-1 with in situ winds from three moored buoy arrays: Global Tropical Moored Buoy Array (GTMBA), National Data Buoy Center (NDBC) and Ocean Moored Buoy Network for northern Indian Ocean (OMNI). To assess the agreement between the satellite and in situ observations in different regions, the comparison was split between tropical, extra-tropical and coastal regions for each of the global ocean basins. Furthermore, the agreement between the two wind vector datasets was also estimated at each buoy location separately. Poor circular correlations in wind direction (WD) were observed in regions of shallow bathymetry and low mean wind speed, while some WD errors were found to be associated with the failure to resolve directional ambiguity.

description: Alliances between managed care plans and public health agencies are a growing phenomenon in local health care markets, with profound implications for health care quality, cost, and accessibility. A typology of interorganizational relations between managed care plans and local public health agencies is drawn from observations of over 60 public health jurisdictions. Relations are described along three dimensions corresponding to the strategic intent, functional operation, and structural design of each alliance type. The identified models of interaction reveal the motivations for forming alliances, the mechanics of their operation, and the possible outcomes. These alliances suggest that a wide range of interorganizational strategies is possible in order to pursue the shared interests of local public health agencies and managed care plans. Nonetheless, public health agencies may face challenges in forging managed care alliances that benefit community-wide populations and that are open to participation by the full spectrum of health care providers in the community.

description: We propose and analyze the design of a programmable photonic integrated circuit for high-fidelity quantum computation and simulation. We demonstrate that the reconfigurability of our design allows us to overcome two major impediments to quantum optics on a chip: it removes the need for a full fabrication cycle for each experiment and allows for compensation of fabrication errors using numerical optimization techniques. Under a pessimistic fabrication model for the silicon-on-insulator process, we demonstrate a dramatic fidelity improvement for the linear optics CNOT and CPHASE gates and, showing the scalability of this approach, the iterative phase estimation algorithm built from individually optimized gates. We also propose and simulate a novel experiment that the programmability of our system would enable: a statistically robust study of the evolution of entangled photons in disordered quantum walks. Overall, our results suggest that existing fabrication processes are sufficient to build a quantum photonic processor capable of high fidelity operation.

description: Ensuring a more equitable distribution of vaccines worldwide is an effective strategy to control global pandemics and support economic recovery. We analyze the socioeconomic effects - defined as health gains, lockdown-easing effect, and supply-chain rebuilding benefit - of a set of idealized COVID-19 vaccine distribution scenarios. We find that an equitable vaccine distribution across the world would increase global economic benefits by 11.7% ($950 billion per year), compared to a scenario focusing on vaccinating the entire population within vaccine-producing countries first and then distributing vaccines to non-vaccine-producing countries. With limited doses among low-income countries, prioritizing the elderly who are at high risk of dying, together with the key front-line workforce who are at high risk of exposure is projected to be economically beneficial (e.g., 0.9%~3.4% annual GDP in India). Our results reveal how equitable distributions would cascade more protection of vaccines to people and ways to improve vaccine equity and accessibility globally through international collaboration.

description: Abstract
 Within the scope of licensed warehousing, transaction cost differences arising from support and incentives are noticed between the transactions performed as EWR and the transactions performed in the sales halls of the commodity exchanges. In order to distinguish this cost, the support and incentives provided to the parties that perform transactions in the Licensed warehousing system and the comparative transaction costs of transactions performed in the sales halls of the commodity exchanges are based on a sample application. The amount the parties receive and the costs incurred are attempted with a sale of 45 days of post-storage in both the same dated spot sales, licensed warehouses and traditional ways. it has been established that the main factor that provides an advantage in the transaction costs in commodity exchanges and mercantile exchange in spot sales with the same date is the state incentives for the licensed warehousing system and the price differences between low transaction costs and the markets. The main factor that provides an advantage in the transaction costs of 45 days of post-storage sales in the mercantile exchange is government incentives for Licensed warehousing and the loss of traditional storage has been detected to increase sales transaction costs in the commodity exchanges. In addition, the failure to store specific products in Licensed warehouse has made commodity exchange lounges more appealing to the vendor entity for product market prices. The study concluded that application findings have been up-to-date, allowing market participants in the relevant commodity exchanges markets can view their costs through an analytical perspective.

description: The updating of the local topological relationship can significantly lower the cost (time and money). Previous studies rarely consider the impact of topology change region on updating efficiency and accuracy. In this study, three basic concepts that can quantify the geometric change domain, the topological change domain, and the topological local updating calculation domain are proposed to represent the influence of new points, lines and areas on geometry and topological relationship. They are denoted as GCD, TCD and TLUCD, respectively. And the calculation models of three change domains are verified by taking the topology update of a city as an example. Research shows: 1. The GCD is the area where the geometric change elements are located, and the association relationship change domain is the union of geometric change elements. From the perspective of scope, the GCD and the association relationship change domain are equal. 2. The TCD is the union of GCD and adjacency relationship change domain, which refers to the union of element change region and its adjacent region. In terms of scope, TCD and adjacency relationship change domain are equal. 3. The TLUCD is the union of TCD and its neighborhood. In conclusion, the determination of the local update calculation area provides theoretical support for the study of local updating of the topology. Furthermore, it lays a foundation for studying the change mechanism of topological relationship caused by other composite geographical events.
X-ray news from RW Auriga: Optical dimming with iron rich plasma and an exceptional column density
Creators: name: Guenther, Hans Moritz
Publisher: name: Zenodo
Year: 2018

description: RW Aur A has undergone a visual dimming event in 2011 lasting about half a year and further dimming since 2014. We report on new Chandra X-ray data taken in 2017, when the optical flux was almost 2 mag below the long-term average. The observed X-ray spectrum is more absorbed by a column density of a few 1e23/cm^2 and shows significantly more hot plasma than in X-ray observations taken before the dimming. An emission feature at 6.62 keV indicates an Fe abundance an order of magnitude above Solar, in contrast with previous sub-Solar Fe abundance measurements. Comparing X-ray absorbing column density N_H and optical reddening A_V, we find that either the gas-to-dust ratio in the absorber is orders of magnitude higher than in the ISM or the absorber has undergone significant dust evolution. Given the high column density coupled with changes in the X-ray spectral shape, this absorber is probably located in the inner disk. We speculate that a break-up of planetesimals or a terrestrial planet could supply large grains causing gray absorption; some of these grains would be accreted and enrich the stellar corona with iron which could explain the inferred high abundance.

description: Abstract
 This study addressed the Salam and Parallel Salam contracts with the perspective of conventional and Islamic trade. The futures process is based on an example of a practice on the use of Parallel Salam contracts as an alternative instrument in commodity exchanges. In this context, the differences of Parallel Salam contracts with conventional futures contract are presented. Natural and legal persons, investors, industrialists and merchants may be parties to the transactions under the Salam and Parallel Salam contracts, or they may also be Islamic exchange commodity funds. Considering that the Islamic commodity funds within the scope of agricultural commodities in compliance with the Islamic Law, performing the salam and parallel salam transactions under the commodity exchange will contribute to the depth and transparency of market transactions. The study indicates that Salam and Parallel Salam contracts can be used as alternative instruments in commodity exchanges as a real alternative to conventional commodity exchange futures contracts.

description: Soil Particle Size Distribution (PSD) is a fundamental physical property that can affect soil hydraulic properties, soil structure characterization, and available water. Many models have been applied to define the PSD curve, but predicting the spatial distribution information of PSD has been rarely investigated. Therefore, the main objective of the current study was to predict soil texture fractions using the most accurate PSD models. First, the performance of 16 mathematical PSD models was evaluated. Then, Random Forest (RF) was used to determine the relationship between covariates (i.e., remote sensing and the digital elevation model) and georeferenced measurements of the best PSD models’ parameters. Results indicated that a PSD model may be acceptable for some particle diameters or even whole particles, but not necessarily be suitable for other particles. For example, in the estimation of sand content, the best model was Simple Lognormal, while the Fred-4p was the best model in the estimation of the clay fraction. Importantly, the Jaky model with only one parameter of P did a great job in predicting soil particle fractions. Further, the spatial distribution of clay, silt, and sand contents was accurately derived from the predicted map of P (R2 for Sand = 0.86). Consequently, the current research indicated that the combination of PSD models and digital soil mapping techniques can be used to quantify the spatial distribution of the PSD curve in other similar agroclimatological regions.

description: Persons with psychiatric disorders comprise the largest diagnostic group of disabled recipients of Supplemental Security Income (SSI) and Social Security Disability Income (SSDI). A 32-month prospective cohort study of pathways to application for and receipt of SSI and SSDI was conducted among 169 people with major psychiatric disorders who were at an early stage of their illness and who had never applied for or received disability income. Of the three pathways that formed the conceptual basis for the investigation—labeling, impairment, and needs/resources—the latter two emerged as significantly associated with receipt. Individuals with more severe symptoms who were African American, and who were psychologically dependent in a primary relationship and financially dependent on their families, were more likely to become recipients. Enabling and disabling aspects of disability income receipt suggest that it may be replacing prolonged hospitalization as the most enduring social role of persons with severe, persistent psychiatric disorders.

description: We study the temperature profile, pion spectra and HBT radii in central symmetric and boost-invariant nuclear collisions using a super hybrid model for heavy-ion collisions (SONIC) combining pre-equilibrium flow with viscous hydrodynamics and late-stage hadronic rescatterings. In particular, we simulate Pb+Pb collisions at Sqrt(s)=2.76 TeV, Au+Au, Cu+Cu, Al+Al, and C+C collisions at Sqrt(s)=200 GeV and Au+Au, Cu+Cu collisions at Sqrt(s)=62.4 GeV. We find that SONIC provides a good match to the pion spectra and HBT radii for all collision systems and energies, confirming earlier work that a combination of pre-equilibrium flow, viscosity and QCD equation of state can resolve the so-called HBT puzzle. For reference, we also show p+p collisions at Sqrt(s)=7 TeV. We make tabulated data for the 2+1 dimensional temperature evolution of all systems publicly available for the use in future jet energy loss or similar studies.

title: Vergleich zweier dämonologischer Traktate der Frühen Neuzeit
Creators: name: Lenz, Claudia
Year: 2022

description: Diese Masterarbeit beschäftigt sich mit dem Vergleich zweier dämonologischer Traktate aus dem 16. Jahrhundert. Das eine wurde von Martin Del Rio, einem Jesuiten aus den spanischen Niederlanden, im Jahr 1600 mit dem Titel Disquisitionum magicarum libri sex veröffentlicht, das andere von dem französischen Staatstheoretiker Jean Bodin, erschienen 1581 unter dem Titel De la démonomanie des sorciers. Wichtig dabei ist der Begriff der "Dämonologie", der in der frühen Neuzeit etabliert und für die Hexenverfolgungen im europäischen Raum ideologisch maßgeblich wurde. Im Zuge dieser Arbeit werden einerseits die Autoren und ihre Werke in ihrem historischen Kontext situiert, andererseits die beiden Werke auf Gemeinsamkeiten und Unterschiede in Bezug auf Inhalt, Aussagekraft und Legitimation ihrer Argumentationen untersucht. Der Vergleich steht damit sowohl als Methode wie auch als zentrales Ziel im Mittelpunkt der Arbeit und soll erstmals diese zwei dämonologischen Werke miteinander in Beziehung setzen.
title: Das Novum in der Übersetzung von Science Fiction-Literatur
Creators: name: Philipp, Brendan
Year: 2022

description: Untersuchungsgegenstand dieser Masterarbeit ist der erste Teil der Science-Fiction-Romanreihe The Expanse von James S.A. Corey, Leviathan Wakes (2011), und dessen deutschsprachige Übersetzung Leviathan Erwacht (2012) von Jürgen Langowski. Die Untersuchung widmet sich der Textwelt des Ausgangstextes, Leviathan Wakes, und deren Beschreibung anhand des Novums nach Darko Suvin, einem Kernelement der Narration und Textweltbeschreibung von Science-Fiction-Texten. Ziel dieser Arbeit ist es festzustellen, ob es durch die Übersetzung der Nova des Ausgangstextes zu Veränderungen in der Beschreibung der Textwelt kommt, wie sich diese subsequent im Zieltext manifestieren und ob diese Veränderungen Auswirkungen auf die Narration haben. Das theoretische Fundament dieser Untersuchung ist eine funktionsbasierte, die sich auf den (literatur-)übersetzungswissenschaftlichen Ansätzen von Christiane Nord, der wiederum die Skopostheorie von Katharina Reiß und Hans Josef Vermeer zugrunde liegt, stützt.
description: Subject of this Master‘s thesis is the first part of the sci-fi novel series The Expanse by James S.A. Corey, Leviathan Wakes (2011), and its German translation, Leviathan Erwacht (2012). The analysis of this thesis focuses on the text world of Leviathan Wakes and its description by the Novum, a core element of sci-fi literature and narration, first described and developed by Darko Suvin. The aim of this paper is to determine whether the translation of the source text Nova leads to a different depiction of the text world in the target text, and what the narrative consequences of such differences are. The theoretical foundation for this analysis a functionalist one, based on the (literary) translational theories and concepts by Christiane Nord, which in turn is based on the skopos theory, developed by Katharina Reiß and Hans Josef Vermeer.

description: We present the results of lattice QCD calculations of the magnetic moments of the lightest nuclei, the deuteron, the triton and ${}^3$He, along with those of the neutron and proton. These calculations, performed at quark masses corresponding to $m_π\sim 800$ MeV, reveal that the structure of these nuclei at unphysically heavy quark masses closely resembles that at the physical quark masses. In particular, we find that the magnetic moment of ${}^3$He differs only slightly from that of a free neutron, as is the case in nature, indicating that the shell-model configuration of two spin-paired protons and a valence neutron captures its dominant structure. Similarly a shell-model-like moment is found for the triton, $μ_{{}^3{\rm H}} \sim μ_p$. The deuteron magnetic moment is found to be equal to the nucleon isoscalar moment within the uncertainties of the calculations.

description: Land subsidence (LS), which mainly results from poor watershed management, is a complex and nonlinear phenomenon. In the present study, LS at a country-wide assessment of Iran was mapped by using several geo-environmental conditioning factors (namely, altitude, slope degree and aspect, plan and profile curvature, distance from a river, road or fault, rainfall, geology and land use) into a machine learning algorithm-based artificial neural network (ANN), and a powerful group method of data handling (GMDH). The total dataset includes historical LS and non-LS locations, identified by the interferometric synthetic aperture radar (InSAR). The whole dataset was divided into two subsets at a ratio of 70:30 for training and validating the model, respectively. ANN- and GMDH-based LS maps were evaluated using receiver-operator characteristic (ROC) curves. The information gain ratio (IGR) was calculated to determine the relative importance of the conditioning factors. The results showed that all of the considered factors contributed significantly to the LS mapping in Iran, with geology having the strongest impact. According to the ROC curve analysis, both ANN and GMDH-based LS maps were accurate, but the map obtained by the GMDH approach had a higher accuracy than that of ANN. Southwestern, northeastern and some parts of the central region of Iran were shown to be susceptible to LS in the future. According to the GMDH susceptibility map, 10% of Iran exhibits high or very high susceptibility to LS in the future. The provinces of Hamedan and Khouzestan had the highest percentage of areas at risk of LS. According to the InSAR deformation map, 39%, 20%, 25%, 13% and 3% of the investigated areas are subject to a yearly LS of −1 to −2.5, −2.5 to −5, −5 to −7.5, −7.5 to −10 and −10 to −20 cm, respectively. The province of Razavi Khorasan in the northeast of Iran had the largest area (about 3500 km2) vulnerable to LS occurrence. Based on the LS susceptibility map, the provinces of Ardebil, Kurdistan, West and East Azerbaijan, Sistan and Baluchistan and Kermanshah, although not currently undergoing a high rate of LS, will be at high risk of severe LS in the future.
