Social Media Data in an Augmented Reality System for Situation Awareness Support in Emergency Control Rooms
2021
AbstractDuring crisis situations, emergency operators require fast information access to achieve situation awareness and make the best possible decisions. Augmented reality could be used to visualize the wealth of user-generated content available on social media and enable context-adaptive functions for emergency operators. Although emergency operators agree that social media analytics will be important for their future work, it poses a challenge to filter and visualize large amounts of social media data. We conducted a goal-directed task analysis to identify the situation awareness requirements of emergency operators. By collecting tweets during two storms in Germany we evaluated the usefu…
Multicanonical Monte Carlo simulations
1998
Canonical Monte Carlo simulations of disordered systems like spin glasses and systems undergoing first-order phase transitions are severely hampered by rare event states which lead to exponentially diverging autocorrelation times with increasing system size and hence to exponentially large statistical errors. One possibility to overcome this problem is the multicanonical reweighting method. Using standard local update algorithms it could be demonstrated that the dependence of autocorrelation times on the system size V is well described by a less divergent power law, τ∝Vα, with 1<α<3, depending on the system. After a brief review of the basic ideas, combinations of multicanonical reweighting…
A Swanson-like Hamiltonian and the inverted harmonic oscillator
2022
We deduce the eigenvalues and the eigenvectors of a parameter-dependent Hamiltonian $H_\theta$ which is closely related to the Swanson Hamiltonian, and we construct bi-coherent states for it. After that, we show how and in which sense the eigensystem of the Hamiltonian $H$ of the inverted quantum harmonic oscillator can be deduced from that of $H_\theta$. We show that there is no need to introduce a different scalar product using some ad hoc metric operator, as suggested by other authors. Indeed we prove that a distributional approach is sufficient to deal with the Hamiltonian $H$ of the inverted oscillator.
Digital Image Analysis Applied to Tumor Cell Proliferation, Aggressiveness, and Migration-Related Protein Synthesis in Neuroblastoma 3D Models
2020
Patient-derived cancer 3D models are a promising tool that will revolutionize personalized cancer therapy but that require previous knowledge of optimal cell growth conditions and the most advantageous parameters to evaluate biomimetic relevance and monitor therapy efficacy. This study aims to establish general guidelines on 3D model characterization phenomena, focusing on neuroblastoma. We generated gelatin-based scaffolds with different stiffness and performed SK-N-BE(2) and SH-SY5Y aggressive neuroblastoma cell cultures, also performing co-cultures with mouse stromal Schwann cell line (SW10). Model characterization by digital image analysis at different time points revealed that cell pro…
Traceable hierarchical attribute-based authentication for the cloud
2015
When data owners store their data on cloud servers, they may want to define the access requirements themselves, where attribute-based authentication (ABA) can be a good choice for the solution. In this paper, we propose a traceable hierarchical ABA (HABA) solution which fits two situations in the cloud. The first situation is when cloud users are organized in groups of a hierarchical structure and the access allowance can only be granted to users in a specific group. The second situation is that attributes are organized in a hierarchical structure with different priorities, such that only users who own the required attributes of a specific priority can be authenticated and access the data. …
A new Alokistocaridae Resser, 1939 (Trilobita) from the middle Cambrian of Spain
2012
A new trilobite species, Schopfaspis? graciai, from the middle Cambrian of Spain is the first member of Alokistocaridae reported from west Gondwana. A cladistic analysis of this trilobite and other Gondwanan trilobites of possible alokistocarid affinities (Schopfaspis granulosa, Chelidonocephalus anatolicus, Derikaspis toluni, Kounamkites multiformis) suggests that this family can be divided into two subfamilies: Alokistocarinae and Altiocculinae. Schopfaspis? graciai nov. sp. and Schopfaspis granulosa are assigned to the subfamily Altiocculinae laying in a more basal position than Altiocculus species. The cladistic analysis also demonstrates a possible relationship of Chelidonocephalus ana…
Adwent w liturgiach Kościołów syryjskich ze szczególnym uwzględnieniem tradycji zachodnio-syryjskiej
2022
We wszystkich tradycjach liturgicznych świata chrześcijańskiego Boże Narodzenie poprzedzone jest okresem przygotowania. Z teologicznego punktu widzenia ten okres, Adwent, posiada podwójny wymiar: eschatologiczny oraz nawiązujący do tajemnicy Wcielenia Jezusa Chrystusa. W tradycjach Kościołów syryjskich kolejne niedziele przygotowania do Bożego Narodzenia koncentrują się na przekazanych w Ewangeliach tzw. „zwiastowaniach” (syr.: subārā). Niniejszy artykuł stanowi próbę zarysu idei teologicznych obecnych w euchologii adwentowej Kościołów syryjskich.
single zircon ages and Sm-Nd systematics for precambrian rocks from Madagascar: Significance for correlations in East Gondwana
1998
A blind trilobite with Baltic affinities from Cambrian Series 3 of the Iberian Chains, Spain, and its stratigraphical and palaeobiogeographical signi…
2015
Three cranidia of a conocoryphid trilobite are described from the lower Caesaraugustan Regional Stage (upper part of provisional Cambrian Stage 5 within Cambrian Series 3) in the Iberian Chains, Spain. The material is from the upper part of the Mansilla Formation and the base of the overlying Murero Formation. It closely resembles Bailiella tenuicincta (Linnarsson, 1879), which has previously been described from the Ptychagnostus gibbus (Cambrian Stage 5) and lower P. atavus zones (lower Drumian Stage) of Baltica (Sweden and Bornholm), and from the P. atavus Zone of West Avalonia (Newfoundland). The record of B. cf. tenuicincta from the Mediterranean margin of West Gondwana provides additio…
