The Anthropocene has been mobilised as a conceptual framework for museums to engage with the global environmental crisis. This article examines the exhibition Welcome to the Anthropocene: The Earth in our Hands that was on display at the Deutsches Museum from 2014 to 2016. Proclaimed as the first largescale exhibition on the concept, the museum attempted to translate its underlying arguments into three-dimensional space. Viewing exhibitions as an assemblage of display technologies, objects and texts, the intention is to examine how the concept materialises in the exhibition space. The findings outline three different versions of the Anthropocene: understanding the Anthropocene as a history, experiencing the Anthropocene through spatial exploration and the concept as a tool to catch slippages. Locating three versions in a single exhibition reveals the complexity of the Anthropocene as a framework for museums and also highlights the possibility of addressing it in different ways simultaneously.

AbstractIt is widely recognised that filament disappearances or eruptions are frequently associated with Coronal Mass Ejections (CMEs). Since CMEs are a major source of disturbances of the space environment surrounding the Earth, it is important to investigate these associations in detail for the better prediction of CME occurrence. However, the proportion of filament disappearances associated with CMEs is under debate. The estimates range from $$\sim$$ ∼  10 to $$\sim$$ ∼  90% and could be affected by the manners to select the events. In this study, we aim to reveal what parameters control the association between filament eruptions and CMEs. We analysed the relationships between CME associations and the physical parameters of filaments including their length, maximum ascending velocity, and direction of eruptions using 28 events of filament eruptions observed in H$$\alpha$$ α . We found that the product of the maximum radial velocity and the filament length is well correlated with the CME occurrence. If the product is larger than $$8.0 \times 10^{6}$$ 8.0 × 10 6 $$\text {km}^{2}$$ km 2 $$\text {s}^{-1}$$ s - 1 , the filament will become a CME with a probability of 93%, and if the product is smaller than this value, it will not become a CME with a probability of 100%. We suggest a kinetic-energy threshold above which filament eruptions are associated with CMEs. Our findings also suggest the importance of measuring the velocity vector of filament eruption in three-dimensional space for the better prediction of CME occurrence.

This article considers instances of variation among determinatives within the so-called “Book of the Earth,” as attested in the burial chamber of Ramesses VI. Variants that appear to occur as deliberate contrivances of the ancient authors are distinguished from those that might have arisen as a result of scribal error. The occurrence of variants with thematic or mythological significance and their clustering within the three dimensional space of the burial chamber are then evaluated as evidence for the use of master document(s), which have otherwise been lost, in the execution of the monument’s decorative program.

The author's population density index ( PDI) model is extended to three-dimensional distributions. A derived formula is presented that allows for the calculation of the lower and upper bounds of density in three-dimensional space for any finite lattice.

<div> <div> <div> <p>“Peptoids” was proposed, over decades ago, as a term describing analogs of peptides that exhibit better physicochemical and pharmacokinetic properties than peptides. Oligo-(N-substituted glycines) (oligo-NSG) was previously proposed as a peptoid due to its high proteolytic resistance and membrane permeability. However, oligo-NSG is conformationally flexible and is difficult to achieve a defined shape in water. This conformational flexibility is severely limiting biological application of oligo-NSG. Here, we propose oligo-(N-substituted alanines) (oligo-NSA) as a new peptoid that forms a defined shape in water. A synthetic method established in this study enabled the first isolation and conformational study of optically pure oligo-NSA. Computational simulations, crystallographic studies and spectroscopic analysis demonstrated the well-defined extended shape of oligo-NSA realized by backbone steric effects. The new class of peptoid achieves the constrained conformation without any assistance of N-substituents and serves as an ideal scaffold for displaying functional groups in well-defined three-dimensional space, which leads to effective biomolecular recognition. </p> </div> </div> </div>

AbstractBiofilms are microbial communities that represent a highly abundant form of microbial life on Earth. Inside biofilms, phenotypic and genotypic variations occur in three-dimensional space and time; microscopy and quantitative image analysis are therefore crucial for elucidating their functions. Here, we present BiofilmQ—a comprehensive image cytometry software tool for the automated and high-throughput quantification, analysis and visualization of numerous biofilm-internal and whole-biofilm properties in three-dimensional space and time.

AbstractThe selection and manipulation of objects in Virtual Reality face application developers with a substantial challenge as they need to ensure a seamless interaction in three-dimensional space. Assessing the advantages and disadvantages of selection and manipulation techniques in specific scenarios and regarding usability and user experience is a mandatory task to find suitable forms of interaction. In this article, we take a look at the most common issues arising in the interaction with objects in VR. We present a taxonomy allowing the classification of techniques regarding multiple dimensions. The issues are then associated with these dimensions. Furthermore, we analyze the results of a study comparing multiple selection techniques and present a tool allowing developers of VR applications to search for appropriate selection and manipulation techniques and to get scenario dependent suggestions based on the data of the executed study.
