We easily distinguish self-touch from the touch of others. This distinction is suggested to arise because the brain predicts the somatosensory consequences of voluntary movements using an efference copy and attenuates the predicted self-touch. However, it remains unclear how these predictions impact somatosensory perception before or after the self...

The primary drivers of the thermal sensitivity of ectothermic organisms' task performance remain uncertain, with the potential for changes in mobility, cognitive ability, or the interaction between these factors to be considered. Similarly, it is unclear whether the relationship between these processes varies with experience or task difficulty. The...

We have established that a black hole is a factory for the decomposition of body mass into individual quarks that are absorbed by the black hole. No body or particle can reach the surface of a black hole without decaying into quarks. We have established the effect of a complete mass defect when a body (particle) falls into a black hole (the Leonov...

Wind plays a crucial role in the movement and accumulation of sand in the Tafilalet Oasis. It is the primary driver of variations in the morphological forms of sand accumulation, as well as the direction of dune development and movement. This dynamic has significant socio-spatial consequences for the region. This study emphasizes the fundamental ro...

Public participation has significantly developed since the 1980s. While public participation is commonly expected to bring better knowledge, better decision implementation and better democracy, the reality shows that it does not always lead to these benefits. This chapter provides explanations for this discrepancy between expected and observed bene...

The reliability of a scientific research is one of the most important indices of its validity. The high reliability of a research (often more than 60 percent) means that when a research is applied in different times or by different persons, the same conclusion will be reached. Although coding the interview data is one of the most important processe...

The Great Salt Lake reached the lowest water volume in its entire 170+ year record in 2022. To explain this record low we develop and apply a lake mass‐balance model and perform four simulations: one where all input and output variables are fixed to their mid‐20th century average resulting in an equilibrium lake volume, and three others where one o...

Many Americans express a mix of conservative and liberal views across issues. Prior research indicates these voters are cross-pressured. A recent, influential article “Moderates” (Fowler et al. 2023) argues that these voters instead largely have centrist views on individual issues. To reach this conclusion, “Moderates” develops a method to determin...

In the equilibrium of a game, no player has an incentive to unilaterally deviate from equilibrium play. At the same time, players may have no positive incentive to follow equilibrium when every other player follows equilibrium, e.g., as in a mixed-strategy Nash equilibrium. This paper concerns the incentives of players to follow equilibrium in sequ...

The original model of axion natural inflation produces a tensor-to-scalar ratio above the experimental limit. Aligned axion inflation admits inflationary trajectories that originate near a saddle point of the two-field potential, and terminate due to the instability of the orthogonal direction. The phenomenology of these solutions is within the cur...
