description: The efficiency of supported catalysts depends on the porous microstructure of their solid support, which regulates mass transfer, exposure to the active phase, and mechanical strength. Here, we focus on the manufacturing of a specific type of catalytic support, $γ$-alumina extrudates, by a kneading-extrusion process. In this process, a paste is initially formed by blending and subsequently kneading a boehmite powder, an aluminum oxide hydroxide precursor of $γ$-alumina, with various liquids before undergoing extrusion. The crucial step in this process is the kneading step, which allows control over the textural and mechanical properties of the extrudate. The present experimental study aims to measure the impact of the kneading step on boehmite pastes prepared using a pilot kneader. The pastes are obtained by mixing boehmite powder with an acid and a basic solution in a two-step process known as peptization and neutralization. In this study, kneading is conducted at various mixing speeds and durations while monitoring the torque exerted by the boehmite paste on the kneader blades. Moreover, samples are extracted from the pilot kneader at various stages of the kneading process, and their textural properties are determined by both nitrogen sorption and mercury intrusion porosimetry. Our findings show that, at fixed composition, the textural properties of boehmite pastes are controlled by the overall deformation accumulated during kneading. Conversely, for a fixed accumulated deformation, the pH sets the textural properties. Finally, we identify an empirical control parameter that captures the combined effects of pH and accumulated deformation on the key textural attributes of boehmite pastes. These results set the stage for a systematic design approach of boehmite-based catalyst supports.

description: This article discusses the concept of rational equivalence in tropical geometry (and replaces the older and imperfect version arXiv:0811.2860). We give the basic definitions in the context of tropical varieties without boundary points and prove some basic properties. We then compute the "bounded" Chow groups of $\mathbb{R}^n$ by showing that they are isomorphic to the group of fan cycles. The main step in the proof is of independent interest: We show that every tropical cycle in $\mathbb{R}^n$ is a sum of (translated) fan cycles. This also proves that the intersection ring of tropical cycles is generated in codimension 1 (by hypersurfaces).

description: Recent observational evidence suggests that the coarse angular resolution ($\sim20"$ FWHM) of single-dish telescopes at sub-mm wavelengths has biased the observed galaxy number counts by blending together the sub-mm emission from multiple sub-mm galaxies (SMGs). We use lightcones computed from an updated implementation of the \galform semi-analytic model to generate $50$ mock sub-mm surveys of $0.5$ deg$^2$ at $850$ $μ$m, taking into account the effects of the finite single-dish beam in a more accurate way than has been done previously. We find that blending of SMGs does lead to an enhancement of source extracted number counts at bright fluxes ($S_{\mathrm{850}μ\mathrm{m}}\gtrsim1$ mJy). Typically, $\sim3{-}6$ galaxies contribute $90\%$ of the flux of an $S_{850μ\mathrm{m}}=5$ mJy source and these blended galaxies are physically unassociated. We find that field-to-field variations are comparable to Poisson fluctuations for our $S_{850μ\mathrm{m}}>5$ mJy SMG population, which has a median redshift $z_{50}=2.0$, but are greater than Poisson for the $S_{850μ\mathrm{m}}>1$ mJy population ($z_{50}=2.8$). In a detailed comparison to a recent interferometric survey targeted at single-dish detected sources, we reproduce the difference between single-dish and interferometer number counts and find a median redshift ($z_{50}=2.5$) in excellent agreement with the observed value ($z_{50}=2.5\pm 0.2$). We also present predictions for single-dish survey number counts at $450$ and $1100$ $μ$m, which show good agreement with observational data.

description: In den letzten Jahren rückt die Thematik der häuslichen Gewalt und damit verbunden die Gewalt gegen Frauen* immer weiter in den Mittelpunkt des Diskurses. Damit verbunden sind derartige Vorfälle und Taten immer verstärkter in täglichen Medien zu finden. Ziel der Arbeit ist es, die Berichterstattung zu Fällen der Gewalt gegen Frauen* in den drei meistgelesenen österreichischen Tageszeitungen zu analysieren. Mit Hilfe der Kritischen Diskursanalyse nach Jäger wurden jeweils drei Fälle in der Kleinen Zeitung, der Kronen Zeitung und der Heute auf sprachliche Strukturen, grafische Gestaltung und weitere Aspekte der Berichterstattung untersucht. Die Auswertung der Analyse zeigt, dass die Fokussierung der Berichterstattung auf extremen Einzelfällen und medienwirksamen Thematiken beruht. Außerdem werden durch die Art der Berichterstattung klischeehafte Rollenbilder reproduziert. Auf Kontaktdaten und Hilfsangebote von Opferschutzeinrichtungen wurde weitgehend nicht verwiesen. Positiv festgestellt konnte werden, dass in der Berichterstattung weitgehend auf private Details der Täter*innen und Opfer verzichtet wird.
description: In the last years the topic of domestic violence and thereby violence against women* stands more and more in the focus of the social discourse. Because of that such incidents and offenses are found more and more in daily reporting. The aim of this research work is to analyze this coverage in the most read daily newspapers of Austria which are Kleine Zeitung, Kronen Zeitung und Heute. The chosen method for this analysis is the Kritische Diskursanalyse from Jäger. Three cases each covered with three articles were analyzed. The evaluation shows that the reports focus on extreme and individual cases and media effective topics. Furthermore, the reporting reproduces gendered Stereotypes. In addition, there are no contact details from social facilities. On a positive note, there are widely no private details of suspects und victims published.

description: The ICARUS T600 detector, the largest liquid Argon Time Projection Chamber (LAr-TPC) realized after many years of RD activities, was installed and successfully operated for 3 years at the INFN Gran Sasso underground Laboratory. One of the most important issues was the need of an extremely low residual electronegative impurity content in the liquid Argon, in order to transport the free electrons created by the ionizing particles with a very small attenuation along the drift path. The solutions adopted for the Argon re-circulation and purification systems have permitted to reach impressive results in terms of Argon purity and a free electron lifetime exceeding 15 ms, corresponding to about 20 parts per trillion of equivalent O2 contamination, a milestone for any future project involving LAr-TPC's and the development of higher detector mass scales.

description: The SDC_MED_DP2 product contains 55 sliding decadal temperature fields (1955-1964, 1956-1965, 1957-1966, …, 2009-2018) at 1/8° horizontal resolution obtained in the 0-2000m layer and two derived OHC annual anomaly estimates for the 0-700m and the 0-2000m layers. Sliding decades of annual Temperature fields were obtained from an integrated Mediterranean Sea dataset covering the time period 1955-2018, which combines data extracted from SeaDataNet infrastructure at the end of July 2019 (SDC_MED_DATA_TS_V2, https://doi.org/10.12770/3f8eaace-9f9b-4b1b-a7a4-9c55270e205a) and the Coriolis Ocean Dataset for Reanalysis (CORA 5.2, accessed in July 2020, https://archimer.ifremer.fr/doc/00595/70726/). The resulting annual OHC anomaly time series span the 1960-2014 period. The analysis was performed with the DIVAnd (Data-Interpolating Variational Analysis in n dimensions), version 2.6.1.

description: In this paper, we revisit scalar field theories in $d$ space-time dimensions possessing $U(N)$ global symmetry. Following our recent work arXiv:1402.1430v2, we consider the generating function of correlation functions of all $U(N)$-invariant, single-trace operators at the free fixed point. The exact renormalization group equations are cast as Hamilton equations of radial evolution in a model space-time of one higher dimension, in this case $AdS_{d+1}$. The geometry associated with the RG equations is seen to emerge naturally out of the infinite jet bundle corresponding to the field theory, and suggests their interpretation as higher-spin equations of motion. While the higher-spin equations we obtain are remarkably simple, they are non-local in an essential way. Nevertheless, solving these bulk equations of motion in terms of a boundary source, we derive the on-shell action and demonstrate that it correctly encodes all of the correlation functions of the field theory, written as `Witten diagrams'. Since the model space-time has the isometries of the fixed point, it is possible to construct new higher spin theories defined in terms of geometric structures over other model space-times. We illustrate this by explicitly constructing the higher spin RG equations corresponding to the $z=2$ non-relativistic free field theory in $D$ spatial dimensions. In this case, the model space-time is the Schrödinger space-time, $Schr_{D+3}$.

description: Children with cancer require adequate nutritional support to prevent malnutrition. This study investigated the impact of chemotherapy on anthropometrical status and body composition during the first six months of treatment. Anthropometrical status and body composition were measured at diagnosis, utilizing standardized protocols and validated S10 InBody bio-electrical impedance (BIA) measurements and compared to subsequent consecutive monthly follow-up measurements to plot changes over time during the first six months. Statistical significance was defined as p < 0.05. Forty-three newly diagnosed children (median age 4 years, IQR: 2.0-7.6; male-female ratio 1:0.9; 53% haematological malignancies and 47% solid tumors) were included. Prevalence of malnutrition varied, with under-nutrition 14% (mid-upper arm circumference (MUAC)/body mass index (BMI)), over-nutrition 9.3% (BMI) and stunting 7% at diagnosis. MUAC (14%) identified fewer participants with underlying muscle store depletion than BIA (41.8%). Chemotherapy exposure acutely exacerbated existing nutritional depletion during the first two months after diagnosis for all variables except fat mass (FM), with contrary effects on cancer type. Haematological malignancies had rapid increases in weight, BMI and FM. All patients had an acute loss of skeletal muscle mass. Nutritional improvement experienced by all cancer types during month two to three of treatment resulted in catch-up growth, with a significant increase in weight (chi2=40.43, p < 0.001), height (chi2=53.79, p < 0.001), BMI (chi2=16.32, p < 0.005), fat free mass (chi2=23.69, p < 0.003) and skeletal muscle mass (chi2=24.19, p < 0.001) after six months. Monthly nutritional assessments, including advanced body composition measurements, are essential to provide timely nutritional interventions to overcome the acute decline in nutritional reserves observed during the first two months of chemotherapy exposure.

description: The Chesterfield-Bellona atolls and reefs are a vast reef complex located in the Coral Sea Marine Park, established in 2014 in the New Caledonian Economic Exclusive Zone. In 2013, the New Caledonia government supported the first assessment of fish and benthic habitats conducted over the entire area. The assessment provided a primary knowledge base for establishing the importance of these atolls in terms of biodiversity and fished resources. This comprehensive survey relied on an unbaited underwater video technique that enabled to collect 185 successful camera drops distributed over all shallow habitats in the atolls. Video analysis revealed 18 fish species that had not been previously reported in this area. These included commercially important species: two species of snapper (Lutjanus monostigma and Lutjanus rivulatus) and an emperor (Lethrinus atkinsoni). Most of the new species observed displayed relatively low occurrences (< 5 individuals over 185 camera drops). They were observed in three habitats: i) live coral-dominated; ii) debris-dominated; and iii) sandy bottoms. Reference of the survey: CHESTERFIELD-BELLONA 2013: http://dx.doi.org/10.17600/18002030

description: A one-dimensional quantum charge pump transfers a quantized charge in each pumping cycle. This quantization is topologically robust being analogous to the quantum Hall effect. The charge transferred in a fraction of the pumping period is instead generally unquantized. We show, however, that with specific symmetries in parameter space the charge transferred at well-defined fractions of the pumping period is quantized as integer fractions of the Chern number. We illustrate this in a one-dimensional Harper-Hofstadter model and show that the fractional quantization of the topological charge pumping is independent of the specific boundary conditions taken into account. We further discuss the relevance of this phenomenon for cold atomic gases in optical superlattices.

description: Functional and structural ceramics have become irreplaceable in countless high-tech applications. However, their inherent brittleness tremendously limits the application range and, despite extensive research efforts, particularly short cracks are hard to combat. While local plasticity carried by mobile dislocations allows desirable toughness in metals, high bond strength is widely believed to hinder dislocation-based toughening of ceramics. Here, we demonstrate the possibility to induce and engineer a dislocation microstructure in ceramics that improves the crack tip toughness even though such toughening does not occur naturally after conventional processing. With modern microscopy and simulation techniques, we reveal key ingredients for successful engineering of dislocation-based toughness at ambient temperature. For many ceramics a dislocation-based plastic zone is not impossible due to some intrinsic property (e.g. bond strength) but limited by an engineerable quantity, i.e. the dislocation density. The impact of dislocation density is demonstrated in a surface near region and suggested to be transferrable to bulk ceramics. Unexpected potential in improving mechanical performance of ceramics could be realized with novel synthesis strategies.

description: Pazopanib, a receptor tyrosine kinase inhibitor, exhibits anti-tumor activity in adult bone and soft-tissue sarcomas (STS), but has not yet been approved for pediatric tumors. The primary objective was to evaluate pazopanib efficacy when used alone or in combination with topotecan. This real-world multicenter retrospective study included patients with solid tumors, aged 25 years or less at the time of initial diagnosis, treated with pazopanib outside of a clinical trial. Nineteen patients were eligible for efficacy analysis: 14 bone tumors and 5 STS. At pazopanib initiation, the median age was 16.9 years, 18 patients had metastatic disease with a median of 2 prior therapeutic lines. With 6.2 months of median follow-up, no objective response was observed, but 10 patients (52.6%) had stable disease at 8 weeks and the 6-month disease control rate was 26.3%. The median progression free (PFS) and overall survival (OS) were 3.0 months and 6.2 months, respectively. Multivariate analysis showed an inverse relationship between the number of prior treatment lines and PFS and OS (hazard ratio = 1.73 (p = 0.04) and 1.76 (p = 0.03), respectively). Our study showed a potential tumor control activity of pazopanib in pediatric bone and soft tissue sarcomas. Further studies are warranted to determine the optimal timing and condition for pazopanib introduction to maximize the effect.

description: Superconducting circuits have attracted growing interest in recent years as a promising candidate for fault-tolerant quantum information processing. Extensive efforts have always been taken to completely shield these circuits from external magnetic field to protect the integrity of superconductivity. Surprisingly, here we show vortices can improve the performance of superconducting qubits by reducing the lifetimes of detrimental single-electron-like excitations known as quasiparticles. Using a contactless injection technique with unprecedented dynamic range, we quantitatively distinguish between recombination and trapping mechanisms in controlling the dynamics of residual quasiparticles, and show quantized changes in quasiparticle trapping rate due to individual vortices. These results highlight the prominent role of quasiparticle trapping in future development of superconducting qubits, and provide a powerful characterization tool along the way.

description: In this paper we are searching whether the wormhole solutions exists in different dimensional non- commutative inspired spacetimes. It is well known that the noncommutativity of the space is an outcome of string theory and it replaced the usual point like object by a smeared object. Here we have chosen Lorentzian distribution as the density function in the noncommutative inspired space- time. We have observed that the wormhole solutions exist only in four and five dimension, however, higher than fine dimension no wormhole exists. For five dimensional spacetime, we get a wormhole for a restricted region. In usual four dimensional spacetime, we get a stable wormhole which is asymptotically flat.

description: Recent advances in task planning leverage Large Language Models (LLMs) to improve generalizability by combining such models with classical planning algorithms to address their inherent limitations in reasoning capabilities. However, these approaches face the challenge of dynamically capturing the initial state of the task planning problem. To alleviate this issue, we propose AutoGPT+P, a system that combines an affordance-based scene representation with a planning system. Affordances encompass the action possibilities of an agent on the environment and objects present in it. Thus, deriving the planning domain from an affordance-based scene representation allows symbolic planning with arbitrary objects. AutoGPT+P leverages this representation to derive and execute a plan for a task specified by the user in natural language. In addition to solving planning tasks under a closed-world assumption, AutoGPT+P can also handle planning with incomplete information, e. g., tasks with missing objects by exploring the scene, suggesting alternatives, or providing a partial plan. The affordance-based scene representation combines object detection with an automatically generated object-affordance-mapping using ChatGPT. The core planning tool extends existing work by automatically correcting semantic and syntactic errors. Our approach achieves a success rate of 98%, surpassing the current 81% success rate of the current state-of-the-art LLM-based planning method SayCan on the SayCan instruction set. Furthermore, we evaluated our approach on our newly created dataset with 150 scenarios covering a wide range of complex tasks with missing objects, achieving a success rate of 79% on our dataset. The dataset and the code are publicly available at https://git.h2t.iar.kit.edu/birr/autogpt-p-standalone.

description: Trust is a factor that can positively influence human-robot interactions. Transparent robot design and appropriately timed explanations have the potential to help users calibrate their trust in a robotic system. We introduce the idea of robo-tooltips, physical markers that signal to users that additional information about the robot is available, which they can access at their own discretion. We showcase the concept, which is similar to the tooltips used in desktop environments, by attaching QR codes to a robot. When the user interacts with the QR code, descriptions on the capabilities and behavior of the respective part of the robot are displayed. We present scenarios during which the user retrieves information using robo-tooltips. Further, we discuss some opportunities and challenges of offering optional explanations during human-robot interaction and outline directions for future work.

description: As collaborative robots enter industrial shop floors, logistics, and manufacturing, rapid and flexible evaluation of human-machine interaction has become more important. The availability of consumer headsets for virtual and augmented realities has lowered the barrier of entry for virtual environments. In this paper, we explore the different aspects of using such environments for simulating robots in user studies and present the first findings from our own research work. Finally, we recommend directions for applying and using simulation in human-robot interaction.

description: Biometrics systems have significantly improved person identification and authentication, playing an important role in personal, national, and global security. However, these systems might be deceived (or "spoofed") and, despite the recent advances in spoofing detection, current solutions often rely on domain knowledge, specific biometric reading systems, and attack types. We assume a very limited knowledge about biometric spoofing at the sensor to derive outstanding spoofing detection systems for iris, face, and fingerprint modalities based on two deep learning approaches. The first approach consists of learning suitable convolutional network architectures for each domain, while the second approach focuses on learning the weights of the network via back-propagation. We consider nine biometric spoofing benchmarks --- each one containing real and fake samples of a given biometric modality and attack type --- and learn deep representations for each benchmark by combining and contrasting the two learning approaches. This strategy not only provides better comprehension of how these approaches interplay, but also creates systems that exceed the best known results in eight out of the nine benchmarks. The results strongly indicate that spoofing detection systems based on convolutional networks can be robust to attacks already known and possibly adapted, with little effort, to image-based attacks that are yet to come.

title: Der Überwachungskapitalismus des 21. Jahrhunderts im Spiegel der Integrativen Wirtschaftsethik von Peter Ulrich
Creators: name: Wisz, Jakob
Year: 2021

description: Ziel dieser Masterarbeit ist es den Überwachungskapitalismus in seiner gegenwärtigen Funktionsweise zu skizzieren und zu analysieren, um ein Verständnis für die zugrundeliegenden kapitalistischen Mechanismen zu schaffen, die diesen in seiner derzeitigen Ausprägung dominieren. Der von Shoshana Zuboff geprägte Terminus „Überwachungskapitalismus“ dient hierbei als Ausgangspunkt für die wissenschaftliche Auseinandersetzung mit dieser neuen vom Neoliberalismus gepägten Branche, die ihre Gewinne aus der Generierung von personenbezogenen Daten lukriert. Komplexe Regelwerke verschleiern die bei der Anwendung digitaler Produkte damit verbundenen Konsequenzen für die Nutzerinnen und Nutzer. Der dadurch verbundene Verzicht auf Privatsphäre und die Weiterverarbeitung der gewonnenen Daten durch im Überwachungskapitalismus tätige IT-Unternehmen führt zur Etablierung einer neuen Form des Kapitalismus, die als ausschließliche Ressource die extrahierten Informationen über die einzelnen Individuen benötigt. Der Überwachungskapitalismus wird nun der Integrativen Wirtschaftsethik von Peter Ulrich gegenübergestellt, um aufzuzeigen, inwiefern sich dieser in seiner derzeitigen Funktionsweise nicht mit ethischen Gesichtspunkten in Einklang bringen lässt. Zugleich werden durch diesen integrativen Wirtschaftsansatz mögliche Transformationen und Adaptionen aufgezeigt, die einen nach ethischen Kriterien fungierenden Überwachungskapitalismus ermöglichen.

description: Physical embodiment of a robot is a key factor in determining how humans perceive its social role and capabilities. We conducted a pilot design course for three high school students to study the codesign process of robots for societal participation. Our observations from the co-design sessions indicate that when co-designing on an existing robot platform with people with no prior design experience, the physical appearance of the robot can become the driving factor behind the design choices, which presents the challenge of limiting creativity. We propose experience goals and experiential methods such as bodystorming for overcoming the challenge.

description: Professor Roland Jochem from the Technische Universität Berlin is coordinating the European research and innovation project OPENNEXT, a project that is enabling small and medium sized enterprises (SMEs) across Europe to engage in communities with consumers and makers, in order to fundamentally change how products are designed, produced, and distributed. Product creation is inaccessible to most people, but open source hardware (OSH) product designs are available for anyone to modify, make, distribute and sell. OSH offers enormous potential for restructuring the social organisation of product development and reforming conventional industrial practice. This joint participation can bring benefits to both SMEs and consumers. OPENNEXT thus facilitates collaborative product creation by companies and communities of consumers and makers through new mindsets, new business models, and new collaborative software solutions.

description: Sapce-borne gravitational wave antennas, such as LISA and LISA-like mission (Taiji and Tianqin), will offer novel perspectives for exploring our Universe while introduce new challenges, especially in data analysis. Aside from the known challenges like high parameter space dimension, superposition of large number of signals etc., gravitational wave detections in space would be more seriously affected by anomalies or non-stationarities in the science measurements. Considering the three types of foreseeable non-stationarities including data gaps, transients (glitches), and time-varying noise auto-correlations, which may come from routine maintenance or unexpected disturbances during science operations, we developed a deep learning model for accurate signal extractions confronted with such anomalous scenarios. Our model exhibits the same performance as the current state-of-the-art models do for the ideal and anomaly free scenario, while shows remarkable adaptability in extractions of coalescing massive black hole binary signal against all three types of non-stationarities and even their mixtures. This also provide new explorations into the robustness studies of deep learning models for data processing in space-borne gravitational wave missions.

description: In this paper, we present a case study that investigates how users cope with the interactional problems with a multimodal agent in a real-life situation. We conducted a wizard-of-oz study on humanavatar interaction at a science fair and analysed the screen-recorded data of 127 user interactions with the help of conversation analysis. The major problems encountered by users were those of the presence and affordance of the conversational agent. Our results show that wizard-of-oz studies in the wild shed light on these more general fundamental conditions on the interaction, most prominently in the opening section.
