Exploring mutated hilltop inflation in f(ϕ,T) gravity with latest CMB and DESI observations

Biswajit Deb · Atri Deshamukhya

The high-precision observations from the $Planck$ and BICEP/$Keck$ have imposed stringent bounds on the tensor-to-scalar ratio, ruling out many standard inflationary models. The recent bound from Atacama and SPT along with DESI provides a different viable landscape, making it difficult for the inflationary models to su...

Proof of the Andrews–El Bachraoui positivity conjecture

Shane Chern · Chun Wang

We prove that for $k\ge 1$, all coefficients in the expansion of the series $$\sum_{n\ge 0} \frac{(q^{2n+2}, q^{2n+2k}; q^2)_\infty}{(q^{2n+1};q^2)_\infty^2} q^{2n}$$ are positive, by $q$-hypergeometric means. This confirms a recent conjecture of Andrews and El Bachraoui.

New functionalities in MatCont: Delay equations and Lyapunov exponents

Davide Liessi · Enrico Santi · Rossana Vermiglio · Mayank Thakur · y 2 más

MatCont is a powerful toolbox for numerical bifurcation analysis focussing on smooth ODEs. A user can study equilibria, periodic and connecting orbits, and their stability and bifurcations. Here, we report on additional features in version 7p6. The first is a delay equation importer enabling MatCont users to study a mu...

Local asymptotic patterns for viscous approximations of conservation laws

Bressan, Alberto · Caravenna, Laura · Shen, Wen

Solutions to hyperbolic conservation laws can be approximated in many different ways: by vanishing viscosity, relaxations, discrete or semi-discrete numerical schemes, approximation with a nonlocal flux, etc$\ldots$ For some of these methods, general ${\bf L}^1$ convergence results are available. Aim of this paper is t...

Construction of the head and mouth in the earliest jawed vertebrates

Zerina JOHANSON · Lisa SCHNETZ · Ivan SANSOM · Richard DEARDEN · y 2 más

Vertebrates dominate the vast majority of present day ecosystems, but have an obscure early history with the fossil record indicating the prevalence of jawless ‘agnathans’ for the first 50 million years of their evolution. The anatomy of these early jawless vertebrates, and in particular how they fed, is of great impor...

The Spanish moral foundations questionnaire-2: Psychometric properties and predictive associations with intergroup attitudes

Alejandro Magallares · Francesca Valeria Frisari · Cristian Catena-Fernández

The Moral Foundations Questionnaire-2 (MFQ-2) was developed to offer a cross-culturally applicable instrument to assess the core dimensions of human morality. The main goal of the current research was to study the psychometric properties of the Spanish adaptation of the MFQ-2. To this end, we conducted four preregister...
