description: Debris flows can significantly grow along their flow path by entraining sediments stored in the channel bed and banks. This entrainment process is influenced by various factors such as flow properties (e.g., flow momentum, basal shear stress) and environmental conditions (e.g., soil water saturation, sediment availability). In recent years, different attempts to include the entrainment process in runout models have improved modelled flow properties and runout behavior by empirically linking entrainment volumes to individual modelled flow properties. Linking entrainment to environmental factors, however, has remained challenging.

Here, we aim at implementing and testing the influence of flow path water-saturated conditions in debris-flow runout modelling in a Swiss debris-flow basin (Illgraben). To this end, the modified RAMMS runout model, which includes an empirical algorithm to describe entrainment as a function of basal shear stress (Frank et al., 2015), is coupled with a simple hydrological model to predict soil water saturation. In a first step, the RAMMS model was calibrated for the Illgraben site for seven events with detailed data on erosion/deposition along the fan as well as flow properties at the outflow of the simulation domain (de Haas et al., 2022). In the calibration procedure, the focus was placed on the erosion proportionality factor dz/dtau [m/kPa] (which links the maximum potential erosion depth to the basal shear stress) as it is assumed to be the driving saturation-induced increase of entrained volume. Preliminary results show that in most cases, including the entrainment process improves the reproduction of the flow properties, especially the ‘hydrograph’ front, and that the erosion proportionality factor dz/dt shows a significant degree of variation for different events. In a second step, the relationship between soil moisture conditions and maximum erosion depth expected along the flow path was investigated. The hydrologic conditions are simulated with a conceptual model solving the water balance for the basin’s headwaters. The headwater discharge serves as the water input for the channel on the fan, where an infiltration model is applied, and entrainment is investigated. The presented framework, which could be incorporated into other runout models, is expected to be useful for debris-flow entrainment modelling, as well as for assessing climate change impacts on debris-flow runout.

description: Connected and automated vehicles (CAVs) have recently gained prominence in traffic research due to advances in communication technology and autonomous driving. Various longitudinal control strategies for CAVs have been developed to enhance traffic efficiency, stability, and safety in mixed-autonomy scenarios. Deep reinforcement learning (DRL) is one promising strategy for mixed-autonomy platoon control, thanks to its capability of managing complex scenarios in real time after sufficient offline training. However, there are three research gaps for DRL-based mixed-autonomy platoon control: (i) the lack of theoretical collision-free guarantees, (ii) the widely adopted but impractical assumption of skilled and rational drivers who will not collide with preceding vehicles, and (iii) the strong assumption of a known human driver model. To address these research gaps, we propose a safe DRL-based controller that can provide a system-level safety guarantee for mixed-autonomy platoon control. First, we combine control barrier function (CBF)-based safety constraints and DRL via a quadratic programming (QP)-based differentiable neural network layer to provide theoretical safety guarantees. Second, we incorporate system-level safety constraints into our proposed method to account for the safety of both CAVs and the following HDVs to address the potential collisions due to irrational human driving behavior. Third, we devise a learning-based system identification approach to estimate the unknown human car-following behavior in the real system. Simulation results demonstrate that our proposed method effectively ensures CAV safety and improves HDV safety in mixed platoon environments while simultaneously enhancing traffic capacity and string stability.

description: Debris flows and lahars convey large quantities of sediment through fluvial systems in mountainous and volcanic regions. Constraining decadal to centennial patterns of sediment transport by these potentially destructive flows is crucial for understanding their drivers and subsequently modelling the evolution of downstream hazard and channel morphology with time. Relatively few modelling frameworks have been designed to capture sediment transport dynamics at these timescales. Existing models instead tend to either 1) simulate the runout of individual debris flow events or 2) forecast landscape evolution over longer millennial timescales. Our work seeks to address this research gap by developing SedCas. SedCas is a spatially lumped sediment cascade model developed to simulate decadal patterns of sediment transport by debris flows from the Illgraben, an Alpine catchment in Switzerland, into the Rhône River. Its relatively simple structure is computationally inexpensive and has enabled its use in forecasting debris flow hazard and sediment yield from the Illgraben over the 21st century in response to a range of climate change scenarios. Here, we present the first application and adaptation of the SedCas model framework to non-alpine catchments. Firstly, we simulate sediment transport by lahars in a catchment on the island of Montserrat which has been disturbed episodically by explosive volcanism between 1995 - present. In this model iteration, SedCas_Volcano, we account for variations in vegetation cover induced by eruptive events, in addition to water and sediment supply. The model results capture the first-order patterns (aggregate magnitude-frequency) of the largest observed lahars, and the timing and relative order of magnitude of fluctuations in sediment yield. Seasonal and interannual variations in lahar activity are not fully captured, however. We attribute these shortfalls to limitations of available data and the model not accounting for important dynamic hydrological processes that alter runoff generation on evolving volcanic deposits. These limitations in turn provide avenues of further research and development. Secondly, we present preliminary experiments to simulate bedload sediment delivery as input into a new global flood model that accounts for evolving channel geometry.

description: This paper demonstrates the concept of reusing discarded smartphones to connect the end-of-life of e-wastes with the start-of-life of smart buildings. Two control-related and one communication-related case studies have been conducted experimentally to evaluate applicability. Diverse controlled systems, control tasks, and algorithms have been considered. In addition, the sufficiency of communication with external agents has been quantified. The proof-of-concept experiments indicate technical feasibility and applicability to typical tasks with satisfactory performance. As smartphones improve over time, higher computing performance and lower communication latency can be expected, enhancing the prospect of the proposed reuse concept.

description: Debris flows are surging mixtures of water and sediments and can threaten humans and infrastructure. In alpine catchments, debris flows are often triggered by runoff events as a response to intense rainfall, snowmelt, or a combination thereof. Therefore, debris-flow triggering is expected to be sensitive to future changes in temperature and precipitation. Quantifying these changes is, however, challenging. While changes in temperature are relatively certain, future precipitation characteristics have lower signal-to-noise ratios (e.g., Hirschberg et al., 2021). Furthermore, how such changes influence the seasonal snowpack is not trivial. For example, snowmelt is predicted to start earlier in the year, but at lower rates (Musselman et al., 2017). Quantifying climate change impacts on debris-flow triggering runoff events in high-alpine catchments, therefore, requires studying the complex interactions of changes in precipitation, temperature and the snowpack.

Our study focuses on the Grabengufer rock glacier and the gully below, which is located above the municipality of Randa in the canton of Valais, Switzerland. The rock glacier front regularly delivers mobile sediments to the gully (1900 m a.s.l.), where debris flows are frequently triggered after rain and/or snowmelt. We use ALPINE3D, which is a spatially distributed version of the multi-layer snowmodel SNOWPACK (Lehning et al., 2002), to simulate the snowpack evolution and runoff in the Grabengufer basin. Due to the small size and the steepness of the basin, the discharge can be simplified as the snowmelt and liquid precipitation in each pixel and in each timestep. A debris-flow record consisting of 34 events between 1985 and 2016 allowed for calibrating a debris-flow triggering discharge threshold. Ultimately, we plan to use the AWE-GEN stochastic weather generator (Fatichi et al., 2011) and the CH2018 climate scenarios to study changes in debris-flow triggering discharge at hourly resolution. Preliminary results show clear relations between snowmelt, rainfall and debris-flow triggering for the calibration period and provide a proof of concept. Although we cannot address the full complexity of such geomorphic systems leading to debris-flow triggering (e.g., rock-glacier dynamics), we study changes in extreme discharge, which is a key variable for future debris-flow hazards. Furthermore, the studied basin is representative of high-alpine debris-flow torrents and the outcome will be useful for researchers and authorities interested in climate change impacts on alpine mass movements.

description: Porta group
Diagnosis
The porta group can be separated from other Anyphaena species groups by the following characters.
Males
Coxae III and IV smooth or sometimes with ventral tubercles (Figs 41E–F, 51E–F). The general shape of the male palp is similar to that of the pectorosa and pacifica groups. Differs from both of them by having relatively longer palpal tibiae and in the general shape of the RTA. The RTA base is usually restricted to the distal portion of the tibia instead of the medial portion (compare Figs 48E, 49A with Figs 23A, 24A).
Female
Atrium considerably longer than wide. Copulatory openings sometimes covered by the lateral borders of the atrium. Copulatory ducts long and parallel to each other, projecting posteriorly beyond the hood margin (A. porta sp. nov., A.ibarrai sp. nov., A. salgueiroi sp. nov.), although two species (A. tonoi sp. nov. and A. alachua) have shorter copulatory ducts (Fig. 46F, see A. alachua in Supp. file 3). Spermatheca well sclerotized, oval to spherical.

description: Radiocarbon measurements of dissolved organic carbon (DOC) can give us valuable information about origin and age of DOC, a major, yet little understood component in the global carbon cycle. One way to measure DOC in water is to remove dissolved inorganic carbon first, oxidize organic carbon with UV irradiation and ultimately analyses the formed inorganic CO2 for 14C. The main challenge of UV-Oxidation (UVox) methods is to extract the typically low concentrations of DOC with low blanks required for relatively high precision 14C measurements. A disadvantage of currently used UVox methods is that only one sample can be oxidized in a laborious process at the same time in large volume. Here we present a UV-Oxidation system where up to 12 water samples can be oxidized simultaneously in 12 separate quartz reactors arranged around a single UV lamp in a compact setup. The simple setup further uses helium instead of vacuum typically used by conventional extraction lines to speed up the extraction of the formed CO2 after oxidation. The key improvements of the new UVox setup are: 1) Reduced amount of water needed (30- 60 ml) as samples are measured for 14C with the Micadas gas ion source., 2) UV oxidation efficiency for standards is high (96%), 3) No KI trap is needed, 4) Required time for sample preparation of up to 12 samples is 4-6 h, 5) combined the CO2 from different reactors to one trap.  We obtained 2.6 ± 0.6 µgC with F14C= 0.27±0.05 for processing blank.  We will present the first measurments of DOC samples from Swiss lakes, Canadian Beaufort Sea and the reproducibility of the line.

description: The presence of a strong interaction between tectonic deformation and surface processes is widely recognized. Still, the nature of this interaction is difficult to unravel and quantify. In the last decades, analogue landscape evolution models have been widely implemented and employed in different tectonic settings, to complement field campaign studies. Since the aim of these analogue models is to help the interpretation of data coming from natural prototypes, it is important to test how well empirical erosional laws built upon natural landscapes, explain analogue model behavior. We perform a series of experiments for a straight interpretation of the relationship between applied boundary conditions and analogue landscape evolution. The selected analogue material is composed of 40 wt.% of silica powder, 40 wt.% of glass microbeads, and 20 wt.% of PVC powder. The analogue material fills a rectangular box (30×35×5 cm3) placed over a reclined table. Over the box, a series of sprinklers generate a dense mist (i.e., rainfall) that triggers surface processes. The boundary conditions applied to the models are the imposed slope of the reclined table and the rainfall rate. We test three rainfall rates (9, 22, and 70 mm h-1) and three imposed slopes (10, 15, and 20°), analyzing how the combination of these boundary conditions results in different landscape metrics (e.g., basins length, basins width, drainage area, channel slope, erosional efficiency) and erosion rates. Results show that in models affected by high rainfall rates (70 mm h-1), the implemented analogue material is characterized almost no channelization, and erosion acts uniformly and diffusively over the models’ surface. Lower rainfall rates (9, 22 mm h-1) allow more discrete channelization instead. On the other hand, as expected, the imposed slope controls the amount of incision, so that the volumes of material removed by erosion increase moving from 10° to 20°. However, even if the maximum incision is generally controlled by the slope, the coupling with rainfall rate tunes the effectiveness of erosion. In this work we compare the imposed boundary conditions with the corresponding erosion rates, using geomorphic markers and landscape metrics to define if and how natural erosional laws apply to analogue landscape evolution models.

description: We study the ultrafast magnetization dynamics of bcc Fe and fcc Co using the recently suggested heat-conserving three-temperature model (HC3TM), together with atomistic spin- and lattice dynamics simulations. It is shown that this type of Langevin-based simulation is able to reproduce observed trends of the ultrafast magnetization dynamics of fcc Co and bcc Fe, in agreement with previous findings for fcc Ni. The simulations are performed by using parameters that to as large extent as possible are obtained from electronic structure theory. The one parameter that was not calculated in this way, was the damping term used for the lattice dynamics simulations, and here a range of parameters were investigated. It is found that this term has a large influence on the details of the magnetization dynamics. The dynamics of iron and cobalt is compared with previous results for nickel and similarities and differences in the materials' behavior are analysed following the absorption of a femtosecond laser pulse. Importantly, for all elements investigated so far with this model, we obtain a linear relationship between the value of the maximally demagnetized state and the fluence of the laser pulse, which is in agreement with experiments.

description: The surface velocity of debris flows is constantly subject to strong temporal and spatial fluctuations. These are amplified by the pulse-like occurrence of surges throughout the event and by the high variance of the solids fraction. However, continuous information on velocities of multiple consecutive surges within a single debris-flow event with high temporal resolution is rare. In this study, we test a pulse-Doppler (PD) radar over a total torrent length of 180 m. The PD radar utilizes pulsed transmission and provides spatially resolved cells, called range gates, that extend over a width of 20 meters. Doppler velocity spectra composed of velocity classes and echo intensities are obtained at 4 Hz for each range gate. From these, we derived continuous velocity-time data sets. We present PD radar data for three debris flows that occurred on 05.06, 30.06, and 08.09.2022 at the Illgraben creek, Switzerland. The radar data were validated at the first event with a velocity data set obtained from a LiDAR scanner installed at the same location. This novel method collects high-resolution 3D point clouds at 10 Hz. This data was used to derive a high-resolution velocity vector field for one of the events. We isolate a ~ 2x2 m box in the middle of the channel and compare the LiDAR derived velocities at this location to those measured by the PD radar. Our comparison shows a strong correlation between the two data sets, with a coefficient of determination of 0.85. In addition, we note a minor consistent offset in the two velocity data sets of 0.5 m/s. We attribute this to the nature of the different measurement methods and conclude that the two methods may be sensitive to different features of the surface of the flow. However, our results show the high effectiveness and reliability of both methods in debris-flow monitoring. We anticipate that further analysis of the data sets will provide new insights into the geophysical principles of debris flows.

description: Quantum simulators of lattice gauge theories involve dynamics of typically short-ranged interacting particles and dynamical fields. Elimination of the latter via Gauss law leads to infinite range interactions as exemplified by the Schwinger model in a staggered formalism. This motivates the study of long-range interactions, not necessarily diminishing with the distance. Here we consider localization properties of a spin chain with interaction strength growing linearly along the chain as for the Schwinger model. We generalize the problem to models with different interaction ranges. Using exact diagonalization we find the participation ratio of all eigenstates, which allows us to quantify the localization volume in Hilbert space. Surprisingly, the localization volume changes nonmonotonically with the interaction range. Our study is relevant for quantum simulators of lattice gauge theories implemented in state-of-the-art cold atom/ion devices, and it could help to reveal hidden features in disorder-free confinement phenomena in long-range interacting systems.

description: Due to causality wave scattering in time is simpler than scattering in space: In
contrast to multiple spatial boundaries, there are no infinite reflections between
temporal boundaries. Salem and Caloz, 2015 [1] showed that wave scatter-
ing can be simplified by constructing a time-space cross-mapping. We identify
the cross-mapped wavefields as the Focusing functions developed in data-driven
geophysical imaging. Experimentally, Bacot et al, 2016 [2] have shown that
time modulation of the medium properties of a capillary-gravity wave results in
time-refraction and time-reflection of the original wave. This experimental re-
sult should hold true for any system obeying Alembert’s equation. This should
in principle allow us to physically compute wavefields for the single-sided inverse
scattering problem through forward scattering experiments. We set up a sim-
ple comb-like discrete system for time-modulated 1D elastic wave propagation.
Elastic beams act as the masses and an electrostatic force as the springs of our
system. The effective coupling stiffness between the beams is modulated in time
through a variation of the electrostatic force. A Galerkin based wave propaga-
tion model shows that an experimental realization of hundreds of beams can be
achieved through micro-machining. Through time-modulations of the system’s
wavespeed a broadband excitation is refracted and reflected everywhere in space.
Time-scattering preserves the wave vector k, which implies that the frequency
ω is not conserved. To elucidate the dispersion relation at time boundaries,
we employ a correction method for spatial dispersion. Herefore, a correction
method for time-dispersion in finite difference simulations developed by Koene

description: Ridge and LASSO regression are alternative approaches in situations where a large number of predictor variables are available to choose from, and where a high degree of correlation among those predictor variables is possible. These methods guide selection of the most important predictor variables (even from among hundreds) without having to ‘fish’ for significance. The resulting models are parsimonious, with easy to interpret estimates, that also avoid problems with collinearity, biased estimates, and overfitting.

title: Anwendung der Skopostheorie in der Analyse von Prozessen der Übersetzung Technischer Dokumentation
Creators: name: Rader, Julia
Year: 2012

description: In Zeiten der Globalisierung nimmt die mehrsprachige Technische Dokumentationserstellung bzw. -übersetzung einen immer wichtigeren Stellenwert ein. Jede/r BenutzerIn möchte Information, wenn möglich in seiner/ihrer Muttersprache, zum erworbenen Produkt erhalten. Aufgrund dessen ist professionelle, mehrsprachige Technische Dokumentation erforderlich. In dieser Arbeit werde ich versuchen zu klären, was alles dazu erforderlich ist, damit professionelle, mehrsprachige Technische Dokumentation zustande kommen kann, welche Faktoren dabei eine entscheidende Rolle spielen beziehungsweise berücksichtigt werden müssen etc. Aus diesem Grund untersucht die vorliegende Arbeit die Anwendung der Skopostheorie in der Analyse von Prozessen der Übersetzung Technischer Dokumentation, genauer gesagt die Anwendung der Skopostheorie auf die Übersetzung von Bedienungsanleitungen. Sie hat zum Ziel zu untersuchen, ob sich die Skopostheorie für die Übersetzung Technischer Dokumentation anwenden lässt. Es erfolgt eine Analyse der Theorie, die für diese Arbeit relevant ist – Analyse der Skopostheorie, die Rolle der Kultur in der Translation, Grundlagen der Technischen Dokumentation, technische Texte und ihre ÜbersetzerInnen, Technische Handbücher, die Bedienungsanleitung, Normung – durch die sich die praktischen Analysen ziehen.
description: In times of globalisation the creation or translation of multilingual technical documentation is becoming more and more important. Users want information on the purchased technical product in their first language. As a consequence professional, multilingual technical documentation is required. This thesis tries to illustrate all factors that are important to create professional, multilingual technical documentation; which factors play a decisive role or have to be taken into account etc. For this reason, this thesis investigates how the Skopos theory is put into practice when analysing translation processes of technical documentation, especially when translating operating instructions. The main aim of the thesis is to examine if it is possible to apply the Skopos theory when translating technical documentation. The theory, which is relevant to this thesis, is discussed – which includes an analysis of the Skopos theory, what role culture plays in translation, basics of technical documentation, technical texts and their interpreters, technical manuals, operating instructions, standardisation – and this will be illustrated by practical examples throughout the whole thesis.

description: Topic models have been prevalent for decades to discover latent topics and infer topic proportions of documents in an unsupervised fashion. They have been widely used in various applications like text analysis and context recommendation. Recently, the rise of neural networks has facilitated the emergence of a new research field -- Neural Topic Models (NTMs). Different from conventional topic models, NTMs directly optimize parameters without requiring model-specific derivations. This endows NTMs with better scalability and flexibility, resulting in significant research attention and plentiful new methods and applications. In this paper, we present a comprehensive survey on neural topic models concerning methods, applications, and challenges. Specifically, we systematically organize current NTM methods according to their network structures and introduce the NTMs for various scenarios like short texts and bilingual documents. We also discuss a wide range of popular applications built on NTMs. Finally, we highlight the challenges confronted by NTMs to inspire future research. We accompany this survey with a repository for easier access to the mentioned paper resources: https://github.com/bobxwu/Paper-Neural-Topic-Models.

description: We present a method for early detection of lymphatic fluid accumulation in lymphedema patients based on microwave imaging of the limb volume across an air gap. The proposed algorithm uses contour information of the imaged limb surface to approximate the wave propagation velocity locally to solve the eikonal equation for implementing the adjoint imaging operator. This modified backprojection algorithm results in focused imagery close to the limb surface where lymphatic fluid accumulation presents itself. Next, a deep neural network based on U-Net architecture is employed to identify the location and extent of the lymphatic fluid. Simulation studies with various upper and lower arm profiles compare the focusing performance of the proposed contour assisted backprojection imaging with the baseline imaging approach that assumes homogeneous media. The empirical results of the simulation experiments show that the proposed imaging method significantly improves the ability of the deepnet model to identify the location and the volume of the excess fluid in the limb.

description: The residence time of carbon in terrestrial ecosystems, such as soils and freshwater, sets the pace of the terrestrial carbon cycle. Understanding export pathways and turnover times of soil organic carbon (OCSoil) is crucial to assess responses to climate and land use changes. Our study aims to quantify the average turnover time of OCSoil in the catchment of perialpine Lake Constance. Lake sedimentary sequences integrate organic carbon from their catchment and aquatic primary productivity. They act as both burial sites of organic carbon (OC) and time series archives of catchment processes. Thus, they can bridge the gap between plot scale observations, e.g., on soil carbon turnover, and observations made at the outlet of major river systems.

Sedimentary organic carbon sources include aquatic primary productivity, OCSoil, and rock-derived (petrogenic) OC. Stable carbon isotopes (δ13C) can be used to identify the relative contribution of these pools. The 5700-year half-life of radiocarbon (14C) coupled with the atmospheric nuclear bomb spike in the early 1960s can be used to infer the age and turnover rate of the OC pools on millennial to annual timescales. Bulk OC isotope analysis of a varved sediment core spanning the past ca. 110 years at quasi-annual resolution was used to constrain the age of soil carbon delivered to Lake Constance. We combined the geochemical data with a Markov-Chain-Monte-Carlo-based approach to identify the most probable age structure of aquatic and soil-derived OC components and to quantify their respective contributions in addition to petrogenic OC.

Radiocarbon analysis of sedimentary bulk OC reveals a well-defined but muted bomb spike in the early 1960s. However, bulk Δ14COC values remain below 0‰, implying a predominance of aged OC. Based on the δ13C-based three-component linear mixing model, we found these values to be the result of an OC mixture containing approx. 40% pre-aged soil carbon and up to 20% fossil petrogenic carbon.  Accounting for these inputs, we estimated that soil-derived OC delivered to Lake Constance is centennial in age, implying interim storage prior or subsequent to erosion from the landscape.

description: Multi-phase computed tomography (CT) has been widely used for the preoperative diagnosis of kidney cancer due to its non-invasive nature and ability to characterize renal lesions. However, since enhancement patterns of renal lesions across CT phases are different even for the same lesion type, the visual assessment by radiologists suffers from inter-observer variability in clinical practice. Although deep learning-based approaches have been recently explored for differential diagnosis of kidney cancer, they do not explicitly model the relationships between CT phases in the network design, limiting the diagnostic performance. In this paper, we propose a novel lesion-aware cross-phase attention network (LACPANet) that can effectively capture temporal dependencies of renal lesions across CT phases to accurately classify the lesions into five major pathological subtypes from time-series multi-phase CT images. We introduce a 3D inter-phase lesion-aware attention mechanism to learn effective 3D lesion features that are used to estimate attention weights describing the inter-phase relations of the enhancement patterns. We also present a multi-scale attention scheme to capture and aggregate temporal patterns of lesion features at different spatial scales for further improvement. Extensive experiments on multi-phase CT scans of kidney cancer patients from the collected dataset demonstrate that our LACPANet outperforms state-of-the-art approaches in diagnostic accuracy.
