description: We use the framework of Hopf algebra and noncommutative differential geometry to build a noncommutative (NC) theory of gravity in a bottom-up approach. Noncommutativity is introduced via deformed Hopf algebra of diffeomorphisms by means of a Drinfeld twist. The final result of the construction is a general formalism for obtaining NC corrections to the classical theory of gravity for a wide class of deformations and a general background. This also includes a novel proposal for noncommutative Einstein manifold. Moreover, the general construction is applied to the case of a linearized gravitational perturbation theory to describe a NC deformation of the metric perturbations. We specifically present an example for the Schwarzschild background and axial perturbations, which gives rise to a generalization of the work by Regge and Wheeler. All calculations are performed up to first order in perturbation of the metric and noncommutativity parameter. The main result is the noncommutative Regge-Wheeler potential. Finally, we comment on some differences in properties between the Regge-Wheeler potential and its noncommutative counterpart.

description: Arctic rivers will be increasingly affected by the hydrological and biogeochemical consequences of thawing permafrost. During transport, permafrost-derived organic carbon (OC) can either accumulate in floodplain and shelf sediments or be degraded into greenhouse gases prior to final burial. Thus, the net impact of permafrost OC on climate will ultimately depend on the interplay of complex processes that occur along the source-to-sink system. Here, we focused on the Kolyma River, the largest watershed completely underlain by continuous permafrost, and marine sediments of the East Siberian Sea as a transect to investigate the fate of permafrost OC along the land-ocean continuum. Three pools of riverine OC were investigated for the Kolyma main stem and five of its tributaries: dissolved OC (DOC), suspended particulate OC (POC), and riverbed sediment OC (SOC) and compared to earlier findings in marine sediments. Carbon isotopes (δ13C, Δ14C), lignin phenol, and lipid biomarkers show a contrasting composition and degradation state of these different carbon pools. Dual isotope source apportionment calculations imply that old permafrost-OC is mostly associated with sediments (SOC; contribution of 68 ± 10 %), and less dominant in POC (38 ± 8 %), while autochthonous primary production contributes around 44 ± 10 % to POC in the main stem and up to 79 ± 11 % in tributaries. Biomarker degradation indices suggest that Kolyma DOC is relatively degraded, regardless of its generally young age shown by previous studies. In contrast, SOC shows the lowest Δ14C signal (oldest OC), yet relatively fresh compositional signatures. Furthermore, decreasing mineral surface area-normalised OC- and biomarker loadings suggest that SOC is reactive along the land-ocean continuum supporting the idea that floodplain and shelf sediments are efficient reactors. A better understanding of DOC and POC dynamics in Arctic rivers is still necessary, however, this study highlights that sedimentary dynamics play a crucial role when targeting permafrost-derived OC in aquatic systems. Chemical and physical processes (e.g. degradation, sorption) along fluvial-marine transects will determine to what degree thawed permafrost OC may be destined for long-term burial, therewith attenuating further global warming.

description: MARTINI is a popular coarse-grained force-field that is mainly used in molecular dynamics (MD) simulations. It is based on the ``Lego'' approach where intermolecular interactions between coarse-grained beads representing chemical units of different polarity are obtained through water--octanol partition coefficients. This enables the simulation of a wide range of molecules by only using a finite number of parametrized coarse-grained beads, similar to the Lego game, where a finite number of bricks are used to create larger structures. Moreover, the MARTINI force-field is based on the Lennard-Jones potential with the shortest possible cutoff including attractions, thus rendering it very efficient for MD simulations. However, MD simulation is in general a computationally expensive method. Here, we demonstrate that using the MARTINI ``Lego'' approach is suitable for many-body dissipative particle (MDPD) dynamics, a method that can simulate multi-component and multi-phase soft matter systems in a much faster time (about 4--7 times) than MD. In this study, a DPPC lipid bilayer is chosen to provide evidence for the validity of this approach and various properties are compared to highlight the potential of the method. Thus, we anticipate that our study opens new possibilities for faster simulations of a wide range of soft matter systems by using the MDPD method.

description: The gravitational form factors (GFFs) of a hadron encode fundamental aspects of its structure, including its shape and size as defined from e.g., its energy density. This work presents a determination of the flavor decomposition of the GFFs of the proton from lattice QCD, in the kinematic region $0\leq -t\leq 2~\text{GeV}^2$. The decomposition into up-, down-, strange-quark, and gluon contributions provides first-principles constraints on the role of each constituent in generating key proton structure observables, such as its mechanical radius, mass radius, and $D$-term.

Numerical simulation of tire-pavement interaction for noise, safety, and rolling resistance

Publisher: name: No Publisher Supplied
Year: 2018

description: Pavement surface is constructed to provide smooth, safe, quiet, and comfortable driving, which plays an important role in traffic noise, wet weather crash, energy consumption and greenhouse gas (GHG) emission. The challenge of providing pavement with low noise, high friction, and less energy consumption requires systematic and accurate study of the tire-pavement interaction mechanism behind each functional requirement, as well as the methods that can be used to tackle the problem. The main objective of this research is to develop and validate numerical models for the above-mentioned tire-pavement interaction mechanisms and investigate the effect of different pavement surface characteristics on noise, safety, and rolling resistance. Firstly, this study developed a coupled finite element and boundary element method (FEM/BEM) analysis approach for tire-pavement interaction noise simulation and quantified the influence of pavement surface characteristics on generation and propagation of tire vibration noise. Secondly, for safety analysis, this research evaluated hydroplaning risk and skid resistance of multi-lane roadways at different rainfall intensities and the effectiveness of porous friction course (PFC). An analysis framework and methodology was proposed to incorporate consideration of hydroplaning risk in roadway design. Finally, this study investigated tire rolling resistance from the perspective of pavement and quantified the impact of pavement stiffness on fuel consumption and CO2 emission.This study concludes that the pavement surface type with higher texture levels generates greater noise for both porous and non-porous surfaces. The overall noise decreases with the increase of porosity under the same surface texture condition. In addition, the quantification of hydroplaning speed and braking distance using the developed model can help transportation agencies reduce wet-weather safety risk. The study findings can guide the project selection of PFCs at the locations having high hydroplaning risk. Finally, the rolling resistance analysis results indicated the difference of fuel consumption and CO2 emission affected by asphalt pavement layer thickness and pavement temperature are not significant as compared pavement type (flexible vs rigid). This finding suggested that optimal maintenance of roads with good surface characteristics, such as texture and roughness might be a better way to provide greater fuel economy.

description: Characterising fluid flow through rough-walled fractures is of key importance in
order to understand the fluid dynamics of geologic reservoirs. Targets of previ-
ous experimental two-phase studies are; (i) the relative permeability as function
of saturation and wall roughness, (ii) the evaluation of fluid displacement regimes
based on displacement patterns, (iii) the effect of different fracture aperture fields
on displacement patterns. This study uses particle image velocimetry (PIV) to di-
rectly measure fluid velocities during two-phase drainage and imbibition. The novel
approach enables the evaluation of high-resolution velocity fields as function of sat-
uration, capillary number and viscosity ratio. Within a transparent, 3D-printed,
shear-able fracture model, refractive index matched fluids are seeded with fluores-
cent additives. The PIV algorithm recovers fluid velocities from moving particles
in the invading fluid phase and the displacement front. Results show the dynamics
in viscous fingering (VF) and stable displacement (SD) at different capillary num-
bers. During drainage, the local velocity depends strongly of the pattern shape.
The invasion pattern of a viscous finger follows preferential flow paths evaluated in
single-phase flow. Its mean velocity decreases with increasing saturation. During
imbibition, flow channels can be observed in the invading phase. Velocities along the
phase boundary are evaluated for different saturations and discussed. The presented
approach is inherently linked to spatial discretization. With the known aperture,
velocity and saturation in each spatial unit, discharge can be directly calculated as
function of saturation. 3D printing allows to measure two-phase flow in a wide range
of geometries as function of saturation and roughness of the fracture. To realize the
full potential of the PIV approach, the questions of neutrally buoyant particles and
phase separation technique need to be addressed. Possible approaches are existing
and suggested.
A structural affair of atypical Chemokine Receptor 1 and Plasmodium vivax

description: Plasmodium vivax might be a less fatal parasite than P.falciparum but it is widely distributed, infecting ~40% of the world population. Around 130 million cases of P.vivax malaria are reported from south-east Asia and Americas. However, almost none is reported from sub-saharan Africa due to a silencing mutation in Duffy blood antigen that leads to the absence of Duffy Antigen Chemokine Receptor (DARC) on their reticulocytes.

DARC known as Atypical Chemokine Receptor 1 (ACKR1) is a member of the Atypical sub-family of the chemokine receptor family. Characterized by their inability to signal via G-proteins post chemokine binding, ACKRs lacks or have variations in the microswitch motif 'DRY-LAIV'. Unlike other ACKRs, ACKR1 binds non-specifically to both major classes of chemokines, CC- and CXC-. Moreover, ACKR1 interacts with Duffy Binding Protein (DBP) region II of P.vivax and is a point of entry for the parasite. Therefore, understanding the structural dynamics of ACKR1-DBP interaction is a vital component for drug-designing against P.vivax.

In the absence of an X-ray/NMR structure, we present a robust structural model of ACKR1 embedded in an RBC mimic membrane and its interaction with P.vivax DBP. The in-silico study is supported by molecular evolution and GNM based NMA.

On the role of fracture systems in groundwater-driven alpine slope deformation

description: We study the physical mechanisms that drive alpine slope deformation during water infiltration and depletion into fractured bedrocks. We develop a fully coupled hydromechanical model at the valley scale with multiscale fracture systems ranging from meter to kilometer scales represented. The model parameterized with realistic rock mass properties captures the effects of fractures via an upscaling framework with equivalent hydraulic and mechanical properties assigned to local rock mass blocks. The important heterogeneous and anisotropic characteristics of bedrocks due to depth-dependent variations of fracture density and stress state are taken into account and found to play a critical role in groundwater recharge and valley-scale deformation. Our simulation results show that pore pressure actively diffuses downward from the groundwater table during a recharge event, rendering a critical hydraulic response zone controlling surface deformation patterns. During the recession, the hydraulic front migrates downwards and the deformation recorded at the surface (up to ~4 cm) rotates accordingly. The most essential parameters in our model are the fracture network geometry, initial fracture aperture (controlling the rock mass permeability), and regional stress conditions. The magnitude and orientation of our model’s transient annual slope surface deformation are consistent with field observations at our study site in the Aletsch valley. Our research findings have important implications for understanding groundwater flow and slope deformations in alpine mountain environments.

description: We present and evaluate array processing techniques and algorithms for the characterization of snow avalanche signals recorded with Distributed Acoustic Sensing (DAS).

Avalanche observations rely on comprehensive measurements of sudden and rapid snow mass movement that is hard to predict. Conventional avalanche sensors are limited to observations on or above the surface. Recently, seismic sensors have increased in their popularity for avalanche monitoring and characterization due to their avalanche detection and characterization capabilities. To date, however, seismic instrumentation in avalanche terrain is sparse, thereby limiting the spatial resolution significantly.

As an addition to conventional seismic instrumentation, we propose DAS to measure avalanche-induced ground motion. DAS is a technology using backscattered light along a fiber-optic cable to measure strain (-rate) along the fiber with unprecedented spatial and temporal resolution - in our example with 2 m spatial sampling and a sampling rate of 1kHz.

We analyze DAS data recorded during winter 2020/2021 at the Valleé de la Sionne avalanche test site in the Swiss Alps, utilizing an existing 700 m long fiber-optic cable. Our observations include avalanches propagating on top of the buried cable, delivering near-field observations of avalanche-ground interactions. After analyzing the properties of near-field avalanche DAS recordings, we discuss and evaluate algorithms for (1) automatic avalanche detection, (2) avalanche surge propagation speed evaluation and (3) subsurface property estimation.

Our analysis highlights the complexity of near-field DAS data, as well as the suitability of DAS-based monitoring of avalanches and other hazardous granular flows. Moreover, the clear detectability of avalanche signals using existing fiber-optic infrastructure of telecommunication networks opens the opportunity for unrivalled warning capabilities in Alpine environments.

description: Political advertising on social media has become a central element in election campaigns. However, granular information about political advertising on social media was previously unavailable, thus raising concerns regarding fairness, accountability, and transparency in the electoral process. In this paper, we analyze targeted political advertising on social media via a unique, large-scale dataset of over 80000 political ads from Meta during the 2021 German federal election, with more than 1.1 billion impressions. For each political ad, our dataset records granular information about targeting strategies, spending, and actual impressions. We then study (i) the prevalence of targeted ads across the political spectrum; (ii) the discrepancies between targeted and actual audiences due to algorithmic ad delivery; and (iii) which targeting strategies on social media attain a wide reach at low cost. We find that targeted ads are prevalent across the entire political spectrum. Moreover, there are considerable discrepancies between targeted and actual audiences, and systematic differences in the reach of political ads (in impressions-per-EUR) among parties, where the algorithm favors ads from populists over others.

description: Spontaneous bodily sensations (“therapeutic sensations“) are a common phenomenon of complementary and integrative therapies. Our knowledge of their spatial characteristics and meaning (i.e. significance) for the patients is still limited. Here we investigate the phenomenon of therapeutic sensations in a large sample of patients undergoing a TCM-based psychotherapy with acupoint stimulation for various health problems. 108 patients (4 male / 104 female), age: 40.7 ± 9.2 years) who reported unusual sensations during 149 treatments were asked to participate in our survey. Sensations were assessed retrospectively using sensation drawings on a body outline. These were acquired using our recently developed SymptomMapper app running on a Samsung Galaxy Tab 10.1 - a tablet PC equipped with a stylus for easy drawing. It collects information about the intensity (visual analogue scale), quality (list of descriptors), depth (list of descriptors), and location (drawing) of the sensations. Furthermore, we asked patients about the significance that the sensations had for them.
Therapeutic sensations were often wide-spread and involved the extremities as well as the trunk. In the majority of cases they did not follow segmental patterns. Frequently, they were reminiscent of the classical meridians of TCM. Patients used on average 2.60 descriptors (range: 1-13) for their sensations. The mean intensity of therapeutic sensations was 59.9 ± 19.7 on the VAS. The depth localization of the sensations was described as “beneath the skin” (111 sensations), “muscle” (82), “organ” (55), “on the skin” (35), and “bone” (22). Regarding the significance of the sensations, the majority of patients attributed a meaning to them that went beyond the domain of bodily sensations.
Our results show that spontaneous sensations arising during CIM interventions can be strong and wide-spread. When they occur, they are interpreted as an integral part of the therapy and the healing process. Understanding them will bring us closer to unravel the active components of CIM interventions.

description: The Canadian Beaufort Sea receives large quantities of sediment, organic carbon and nutrients from rapid coastal erosion and permafrost degradation. In addition, the Mackenzie River, the largest North American Arctic river, discharges great amounts of freshwater, dissolved solids and suspended sediments to the Beaufort Sea. Current changes in these fluxes in response to the warming climate have uncertain consequences for the carbon budget on the shelf and in the deep ocean. To investigate the movement and transformation of organic matter along the land-ocean continuum, we collected water and surface sediment samples along five major transects across the Beaufort Sea during the 2021 expedition of the Canadian Coast Guard Ship Amundsen. Sampling locations span from shallow, coastal, sites with water depths ≤ 20 m, to shelf-break and deep-water settings on the continental slope (water depths of ≥1000 m). For this study, we use stable and radiocarbon isotopic (δ13C and Δ14C) analyses of dissolved inorganic (DIC), dissolved organic (DOC) and particulate organic carbon (POC) for surface and bottom waters, as well as surface sediments, in order to compare, contrast and constrain the relative source contributions and ages of these different forms of carbon. Our results will help to better understand the fate of permafrost organic matter in the marine environment and to ultimately improve assessments of the Canadian Beaufort Sea shelf as a carbon source or sink and its potential trajectory with ongoing environmental changes.

description: Interactive digital stories provide a sense of flexibility and freedom to players by allowing them to make choices at key junctions. These choices advance the narrative and determine, to some degree, how the story evolves for that player. As shown in prior work, the ability to control or participate in the construction of the narrative can give the player a high level of agency that results in a stronger sense of immersion in the narrative experience. To support the design of this type of interactive storytelling, our system, EntangleVR++, borrows the idea of entanglement from quantum computing. Our use of entanglement allows creators and storytellers control over which sequences of story events take place in correlation with each other, initiated by the choices a player makes. In this work, we evaluated how well our idea of entanglement enables creators to easily and quickly design interactive VR narratives. We asked 16 participants to use our system and based on user interviews, analyses of screen recordings, and questionnaire feedback, we extracted four themes. From these themes and the study overall, we derived four authoring strategies for tool designers interested in the design of future visual interface for interactively creating virtual scenes that include relational objects and multiple outcomes driven by player interactions.

description: A relatively small change in the balance of in- and outgoing fluxes between terrestrial Carbon (Cterr) and the atmosphere, sustained over centuries to millennia can change Cterr from a carbon source to a sink. The net carbon balance of any ecosystem is mainly determined by climate (temperature, humidity, seasonality) via its influence on primary productivity, respiration and preservation, and by geomorphology (erosion). More recently, human perturbance has increasingly also become a major factor. In particular, the slow cycling component of Cterr, with turnover times of centuries to millennia, is relevant for the long-term carbon balance on land. Build-up of this carbon pool is inherently slow, but loss can be rapid and thereby form a significant carbon source to the atmosphere. One way to gain insight in the dynamics of this slow cycling carbon pool is to interrogate sedimentary records that, through time, have stored snapshots of terrestrial carbon, the latter being a mixture of pre-aged, long-stored Cterr and fresh material. By downcore measurements of the radiocarbon age of specific plant-derived organic compounds, interferences by aquatically produced organic carbon or petrogenic organic carbon can be circumvented, and insights can be gained into the carbon cycle processes in the corresponding catchment area. This study presents compound-specific 14C data compiled from studies over the last 20 years of sedimentary records derived from small lake catchments to deltaic and submarine fan deposits near large river mouths. The main conclusions that can be drawn are: 1) Modern but also (pre)historic human perturbance through land-use change has released long-stored ecosystem carbon that otherwise would have escaped mobilization. 2) Both positive and negative correlations between millennial-scale hydroclimate change and Cterr dynamics are evident, and are attributed to the opposing effects on primary productivity, respiration and erosion rates.  3). Catchment size and geomorphology also influence the extent of net ecosystem carbon storage. 4). The Younger Dryas cold period promoted release of Cterr built up during the preceding warm Bølling-Allerød period, illustrating the role rapid climate change can play in carbon dynamics.

description: Understanding the variations in past ocean carbonate chemistry is critical in elucidating the role of the oceans in balancing the global carbon cycle. The fossil shells from marine calcifiers present in the sedimentary record are widely applied as past ocean carbon cycle proxies. However, the interpretation of these records can be challenging due to the complexity physiological and ecological response to the carbonate system during organisms' life cycle, as well as the potential for preservation at the sea-floor. Here we present a new dissolution proxy based on the morphological attributes of coccolithophores from the Noëlaerhabdaceae family (Emiliania huxleyi and Gephyrocapsa spp., > 2 µm). To evaluate the influences of coccolithophore calcification and coccolith preservation on fossil morphology, we measured morphological attributes, mass, length, thickness, and shape factor (ks), of coccoliths in a laboratory dissolution experiment and surface sediment samples in the South China Sea. The coccolith morphological data in surface sediment were also analyzed with environment settings, namely surface temperature, nutrients, pH, chlorophyll-a concentration, and carbonate saturation of bottom water by a redundancy analysis. Statistical analysis indicate that carbonate saturation of the deep ocean explains the highest proportion of variation in the morphological data instead of the environmental variables of the surface ocean. Moreover, the dissolution trajectory in the ks vs length of coccoliths is comparable between natural samples and laboratory dissolution experiments, emphasizing the importance of carbonate saturation on fossil coccolith morphology. However, the mean ks alone cannot fully explain all variations observed in our work. We propose that the mean ks and standard deviation of ks (σ) over the mean ks (σ/ks) could reflect different degrees of dissolution and size-selective dissolution, influenced by the assemblage composition. By applying together with the σ/ks ratio, the ks factor of fossil coccoliths in deep ocean sediments could be a potential proxy for a quantitative reconstruction of past carbonate dissolution dynamics.

description: Am Beispiel Anita Berbers, Ausdruckstänzerin und Lebemensch der Zwanzigerjahre, wird in dieser Arbeit versucht, das Leben nach dem Ersten Weltkrieg mit seinen exzessiven Auswüchsen am Tag und vor allem bei Nacht darzustellen. Eine neu gewonnene Freiheit und ein wildes Ausgelassensein hat nicht nur die Varietés mit ihren Revuegirls und die Nachtklubs beflügelt. Auch der klassische Tanz (Ballett) wurde mit dem aufkommenden Ausdruckstanz, auch ‚moderner Tanz’ genannt, in Deutschland von einer neuen Seite betrachtet. Man hatte zu Beginn der Zwanzigerjahre mit der Inflation und der Entwertung der Reichsmark, die mit einer hohen Arbeitslosigkeit (Kriegsheimkehrer, Invaliden, Spekulanten usw.) einherging, zu kämpfen. Dennoch gab es zur selben Zeit genug Möglichkeiten, das Leben mit seinen Sonnen- und Schattenseiten zu genießen: Nachtleben und Tanz gab es in Berlin in allen möglichen Facetten (Tanzpaläste für die Reichen – Bars und Nachtlokale für die Ärmeren). Etliche junge Frauen strebten voller Enthusiasmus in das Arbeitsleben. Sie waren das Zielpublikum in Sachen Mode, Arbeit, Wohnen und Ausgehen. In den Modezeitschriften fand man für sie (und ihn) die passende Abendgarderobe, die neuesten Haushaltsgeräte, Jobangebote und Reklame der Cafés, die gerade im Trend waren (was sich täglich ändern konnte). Ein neues Gefühl der Körperlichkeit entstand. Die Mode, der Sport, der Tanz und vieles mehr bewirkten ein Sexualitätsverständnis. Homosexualität wurde offen ausgelebt und ausprobiert. Vereine der freien Körperkultur wurden in ganz Deutschland gegründet und hatten regen Zulauf. Beim Ausdruckstanz und beim Striptease war das Entblößen des Körpers Teil der Darstellung und es stellt sich die Frage, inwieweit es bei diesem Kunst war und bei dem anderen nicht. Und wollte der moderne Tanz tatsächlich keine Erotisierung beim Publikum bewirken? Anita Berber war eine dieser Tänzerinnen, die zwischen Kunst und Erotik sowohl im Leben als auch im Tanz balancierte.

description: Genus Anyphaena Sundevall, 1833
Type species
Aranea accentuata Walckenaer, 1802; gender feminine.
Celer group
Diagnosis
The celer group can be separated from other Anyphaena species groups by the following characters.
Males
Coxae lacking ventral spurs (spine-like modifications) but might present clusters of setae (Fig. 3F) or tubercles (cuticle blunt protuberances of various shapes) (Fig. 41E–F). The palp of the celer group (Fig. 1A–C) (Platnick 1974; Platnick & Lau 1975) presents a tegulum divided in three lamella-shaped projections, described as prolateral tegular projection, retrolateral tegular projection and ventral tegular projection following the homologies in Brescovit (1997) and Oliveira & Brescovit (2021). The embolus is a visible sclerite (in the un-expanded palp), tubular in shape, and curved dorsally. The median apophysis (or conductor in Platnick & Lau 1975) is a thin, transparent and curved sclerite, articulated at the base of the ventral tegular projection by flexible cuticle. In expanded pedipalps, the retrolateral tegular projection and prolateral tegular projection are lamella-shaped and partially articulated. In the unexpanded bulb, these projections lie dorsally like two folded tortillas around the other sclerites (Fig. 1A–C). Their RTA is dominated by the anterior and posterior branches, the former usually larger and shaped as a folded cuticular lamella, the latter is usually smaller and its shape varies considerably between species (Platnick 1974, 1977; Platnick & Lau 1975) (Fig. 5A, C).
Females
Externally the epigynum has a hood close to the anterior margin, a sclerotized median plate below the hood, and a transparent atrium delineated by two sclerotized lateral borders. The copulatory openings are difficult to observe; however, they are located near the lateral border's posterior edge (Figs 2A, 4E, 5E, 7E, 8E, 9E, 18A). Internally, the copulatory and fertilization ducts are usually sclerotized and variable in length and shape (Platnick 1974, 1977; Platnick & Lau 1975). The seminal receptacles are cylindrical in shape and also located near the posterior edge. The spermathecae are usually spherical to oval and close to the posterior margin (Figs 2B, 4F, 5F, 7F, 8F, 9F, 18B).

description: This Research Note is based on documentary material that has been for the most part unexplored, i.e., letters and other documents pertaining to Hannah Arendt's relationship with Dorothy Day and the Catholic Worker Movement, on her work with Nancy and Dwight Macdonald for the Spanish Refugee Aid Organization, on her anti-war activities (as well as causes she disavowed), and on her influence on American law discussions. It also analyzes and evaluates Arendt's views on political action, her own and that of others, and uses the earlier findings to illuminate both as well as reconcile her often contradictory statements on the dichotomy between thinking by oneself and acting in concert.

description: We demonstrate that the extended dynamic response of an engineered structure can be obtained from just a single measurement at one position if rotation is recorded in combination with translation. Such a single station approach could save significant time, effort and cost when compared with traditional structural characterization using arrays. In our contribution we will focus on the monitoring of a high-rise building by tracking its dynamic properties, e.g., natural frequencies, mode shapes and damping. We present the results of the system identification for the Prime Tower in Zurich – with a height of 126 m, this concrete frame structure is the third highest building in Switzerland. It has been continuously monitored by an accelerometer (EpiSensor) and a co-located rotational sensor (BlueSeis) located near the building center on the roof for the past year. The motion on the tower roof includes significant rotations as well as translation, which can be precisely captured by the monitoring station. More than 9 natural frequencies, including the first 3 fundamental modes, as well as the next two overtones, where translations are coupled with rotations, are observed between 0.3 – 10 Hz, a frequency band of key interest for earthquake excitation, making an investigation essential. Using temporary arrays of accelerometers located across the roof and along the length of the building to perform a traditional dynamic characterisation, we can compare the array solution with the new single location solution in terms of system identification for the Prime Tower.
