An Explanation of the Landauer bound and its ineffectiveness with regard to multivalued logic
We discuss, using recent results on the thermodynamics of multivalued logic, the difficulties and pitfalls of how to apply the Landauer’s principle to thermodynamic computer memory models. The presentation is based on Szilard’s version of Maxwell’s demon

Quantum Carnot Bound from Petz Recovery Maps
A quantum bound (ηP$\eta_P$, the Petz Limit) is derived for the efficiency (η$\eta$) of a heat engine utilizing two‐level quantum systems (qubits) as the working substance. This limit, based on Petz recovery maps, is stricter than the classical Carnot limit (ηC$\eta_C$) for irreversible cycles.

DEMONIC programming: a computational language for single-particle equilibrium thermodynamics, and its formal semantics. [PDF]
Maxwell's Demon, 'a being whose faculties are so sharpened that he can follow every molecule in its course', has been the centre of much debate about its abilities to violate the second law of thermodynamics.

ABSTRACT Aims Climate change poses severe threats to biodiversity in Australia, particularly for species already at risk from other factors, such as bluetongue lizards (Tiliqua and Cyclodomorphus spp.). Here we model climate‐driven changes in suitable climatic conditions for bluetongue lizards to 2060 and 2100 under multiple climate scenarios and ...

The Evil Enemy: Belief in Conspiracy Theories Predicts Attitudes to War
ABSTRACT Political leaders often justify war with conspiracy theories. How effective are such conspiracy theories in gathering public support for war? The present research has investigated the effects of conspiracy theories on people's war‐related attitudes.

Abstract As nations seek to expand protected area (PA) networks to cover 30% of land and seas by 2030 (30×30), there is an urgent need for systematic conservation planning and spatial prioritization that considers the broad range of ecological and socioeconomic factors influencing the persistence of biodiversity.

The simplicity of physical laws
Abstract Physical laws are strikingly simple, yet there is no a priori reason for them to be so. I propose that nomic realists—Humeans and non‐Humeans—should recognize simplicity as a fundamental epistemic guide for discovering and evaluating candidate physical laws.

Modeling the Formation of Electric and Magnetic Fields in Dust Devils
Abstract Dust devils are a weather phenomenon in which lofted particles become charged through triboelectrification, generating electromagnetic fields. These pose hazards for electronic equipment and affect biological systems. We present a new methodology for simulating the formation of electromagnetic fields within and near dust devils.

Maxwell's demon across the quantum-to-classical transition
In scenarios coined Maxwell's demon, information on microscopic degrees of freedom is used to seemingly violate the second law of thermodynamics. This has been studied in the classical as well as the quantum domain.

DEM simulation of the granular Maxwell’s Demon under zero gravity
In this work, granular segregation in a two-compartment cell (Maxwell’s Demon) under zero gravity is studied numerically by DEM simulation for comparison with the experimental observation in satellite SJ-10.
