Primordial black holes in non-linear perturbation theory [PDF]
, 2009 PhDThe thesis begins with a study of the origin of non-linear cosmological fluctuations. In particular, a class of models of multiple field inflation are considered, with specific reference to those cases in which the non-Gaussian correlation functions

Probing Departures from ΛCDM by Late-time Datasets
The Astrophysical Journal Supplement SeriesObservational data play a pivotal role in identifying cosmological models that are both theoretically consistent and empirically viable. In this work, we investigate the level of preference for dynamical dark energy over a cosmological constant using ...

Local Solvent Ordering Drives Supramolecular Chirality Inversion
Advanced Science, EarlyView.Local solvent organization is shown to govern supramolecular chirality by selecting distinct chiral assembly pathways. A subtle change in water‐DMSO composition reverses the helical sense of a chiral perylene bisimide, while heating induces an irreversible thermal inversion to a more stable enantiomorph.

Exploring hints for dark energy density evolution in light of recent data
Physics Letters B, 2015 Considering a quadratic parameterization of the dark energy density, we explore signatures of evolution using data from gas mass fraction in clusters, type Ia supernova, BAO and CMB.

THE MEASURE OF COSMOLOGICAL PARAMETERS
International Journal of Modern Physics A, 2002 New, large, ground and space telescopes are contributing to an exciting and rapid period of growth in observational cosmology. The subject is now far from its earlier days of being data-starved and unconstrained, and new data are fueling a healthy interplay between observations and experiment and theory.

Programmable Sequential 4D Actuation in Multistable Kirigami Metamaterials
Advanced Science, EarlyView.This study presents a modular kirigami metamaterial framework enabling programmable multistability and sequential 4D actuation. By coupling geometry‐controlled multistability with material‐dependent recovery kinetics, spatiotemporal deformation can be precisely programmed.

The Anatomical Record, EarlyView.Abstract The oval window (OW) is an opening connecting the inner and middle ear. Its area has been shown to consistently scale with body mass (BM) in primates, and has been used alongside semi‐circular canal (SCC) size to differentiate Homo sapiens and fossil hominins, including Paranthropus robustus.

Observational Cosmology with Artificial Neural Networks
Universe, 2022 In cosmology, the analysis of observational evidence is very important when testing theoretical models of the Universe. Artificial neural networks are powerful and versatile computational tools for data modelling and have recently been considered in the ...
