Topology‐based Visual Analysis of Hydrothermal Plumes

Computer Graphics Forum, EarlyView.
Abstract Hydrothermal plumes are turbulent structures of intense heat and mineral smoke that rise and disperse into the deep ocean. Existing models generally characterize these systems as a single axisymmetric plume originating from a point source. However, this assumption breaks down in weakly venting, spatially distributed systems, where low‐flux ...

Modified Friedmann cosmologies—Theory and observations

Annals of Physics, 2005
We investigate a class of Cardassian scenarios of the universe evolution in notions of the qualitative theory of dynamical systems. This theory allows us to analyze all solutions for all possible initial conditions on the phase plane. In the Cardassian models we find that big-rip singularities are present as a typical behavior in the future if $n<0$.

Scalable Computation of Topological Abstractions for Scalar Data

Computer Graphics Forum, EarlyView.
Abstract Topological data analysis has become an important tool for large scale scalar data analysis and visualization, efficiently extracting the inherent structure and features of interest of the data. However, with growing dataset sizes and complexity, it is increasingly becoming infeasible to compute topological abstractions of interest in serial ...

Un/Learning Adult Frames of Reference in Death Enquiries: Thinking~With a Picturebook, Philosophical Animism and Ontological Tact

Children &Society, EarlyView.
ABSTRACT Developmental psychology continues to shape how adults engage with children about death and dying. This influences whether children are included in rituals surrounding human and other‐than‐human bodies. Figurations of the innocent, immature and vulnerable child still dominate adult imaginaries of young children's understandings of mortality ...

Observational Constraints on Loop Quantum Cosmology

Physical Review Letters, 2011
In the inflationary scenario of loop quantum cosmology in the presence of inverse-volume corrections, we give analytic formulas for the power spectra of scalar and tensor perturbations convenient to compare with observations. Since inverse-volume corrections can provide strong contributions to the running spectral indices, inclusion of terms higher ...

Objects of Affection: Deathly Encounters With Taxidermy, Stuffed Toys and Atmospheres

Children &Society, EarlyView.
ABSTRACT This paper explores how children and young people relate to death through affective atmospheres and embodied, imaginative encounters with taxidermy and stuffed toy animals. Using arts‐based research (ABR), we explore how death, affective atmospheres, empathy and materiality entangle during multispecies relations.

The obsolescence of protected area categories in a polycrisis world

Conservation Biology, EarlyView.
Abstract Current global conservation models face significant limitations in addressing the global polycrisis, and the constraints of the International Union for Conservation of Nature protected area (PA) classification system are part of the issue. The principles of the new conservation paradigm—governance, equity, and interculturality—are not viable ...

Undermining the cosmological principle: almost isotropic observations in inhomogeneous cosmologies

Classical and Quantum Gravity, 2000
We challenge the widely held belief that the cosmological principle is an obvious consequence of the observed isotropy of the cosmic microwave background radiation, combined with the Copernican principle. We perform a detailed analysis of a class of inhomogeneous perfect fluid cosmologies admitting an isotropic radiation field, with a view to assessing
