Timing the Sacred: A Multi‐Step Chronological Framework for the Llullaillaco Inca Burial

Archaeometry, EarlyView.
ABSTRACT Absolute radiocarbon dating offers high precision, but its application to historical contexts, such as the Inca civilization, requires a rigorous methodological approach. This research examines methods to enhance chronological accuracy through a case study of artifacts from the Llullaillaco Capacocha sacrifice.

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 ...

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 ...

Observer in Quantum Cosmology

International Journal of Physics Research and Applications
Within the framework of the new formalism of quantum theory - the quantum principle of least action - the initial state of the universe is determined, which is an analogue of the Hartle-Hawking no-boundary wave function. The quantum evolution of the universe is modified by additional conditions in a certain compact region of space-time, which is called

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 $n<0$.

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 ...

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.

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 ...

‘Mature’ and ‘Immature’ Death Concepts: Epistemic Injustice and Young Children's Sense‐Making of Death and Dying

Children &Society, EarlyView.
ABSTRACT Most research in Death Studies focuses on adult perspectives. Even when children are the intended focus, this research often remains adult‐centred due to the dominance of developmental psychology. A key concept underpinning this approach is the ‘mature death concept’ (MDC), a normative framework that assumes children's understanding of death ...

Is Planckian Discreteness Observable in Cosmology?

Universe
A Planck scale inflationary era—in a quantum gravity theory predicting discreteness of quantum geometry at the fundamental scale—produces the scale-invariant spectrum of inhomogeneities with a very small tensor-to-scalar ratio of perturbations and a hot big bang leading to a natural dark matter genesis scenario. Here, we evoke the possibility that some
