Do state borders constrain internal mobility? Evidence from Brazil

This paper documents that state borders are a meaningful source of friction in internal labour mobility in Brazil, a large emerging economy with substantial labour-market informality and historically heterogeneous borders. Using geocoded municipality-to-municipality migration and...

Atomic clocks and gravitational waves as probes of non-metricity

Abstract Non-metricity provides a natural extension of Riemannian geometry, yet its experimental signatures remain largely unexplored. In this work we investigate how spacetime non-metricity can be probed through high-precision observations, focusing on atomic clocks and gravitat...

On Pell, Narayana and Padovan Languages and Their Generalizations

In this article, we study several languages associated with classical integer sequences such as the Pell, Narayana, and Padovan sequences, as well as various generalizations. Some of these languages arise naturally in the context of graph theory. We show that a subset of these la...

Psychometric Properties of the Spanish Version of the Gender Ideology and LGBTQ+ Lobby Conspiracies Scale (GILC): Evidence from a Chilean Sample

Conspiracy beliefs targeting lesbian, gay, bisexual, transgender, and queer (LGBTQ+) individuals have attracted increasing attention in social and political psychology due to their role in prejudice, social exclusion, and resistance to social change. Despite growing interest in t...

Highly suppressed tensor-to-scalar ratio from a modified Lennard–Jones inflationary potential

Abstract The increasingly stringent observational bounds on primordial gravitational waves strongly constrain inflationary model building, favoring scenarios that predict highly suppressed tensor perturbations. While many viable constructions rely on non-canonical kinetic terms,...

Power, Governance and Resilience in a Chilean Fruit Agro-Export Value Chain: A Social Simulation Approach

The fruit agro-export value chain in northern Chile faces governance and water-related challenges that affect its resilience and long-term sustainability. In the context of sustainable agriculture, these challenges highlight the need for integrated approaches to understand how so...
