Bateman gradients from first principles
Nature Communications, 2022 In 1948, Bateman asserted that sexual selection is driven by the sex difference in gamete numbers. Lehtonen presents mathematical models broadly validating this controversial claim, while pointing out selection can be reversed under some conditions.

Protein Repeats from First Principles [PDF]
, 2016 Some natural proteins display recurrent structural patterns. Despite being highly similar at the tertiary structure level, repeating patterns within a single repeat protein can be extremely variable at the sequence level. We use a mathematical definition

Minimum Length from First Principles [PDF]
, 2005 We show that no device or gedanken experiment is capable of measuring a distance less than the Planck length. By "measuring a distance less than the Planck length" we mean, technically, resolve the eigenvalues of the position operator to within that ...

Molecules, 2021 We use density functional theory (DFT) to study the molecular structure and electronic band structure of Sr2Si5N8:Eu2+ doped with trivalent lanthanides (Ln3+ = Ce3+, Tb3+, Pr3+). Li+ was used as a charge compensator for the charge imbalance caused by the

First-principles design of a single-atom–alloy propane dehydrogenation catalyst
Science, 2021 Rhodium atoms for alkane dehydrogenation Nanoparticles of rhodium dispersed on metal oxides are generally poor catalysts for alkane dehydrogenation because the reactants bind too strongly to the metal. Hannagan et al.

Derivation of OTFS Modulation From First Principles [PDF]
IEEE Transactions on Vehicular Technology, 2020 Orthogonal Time Frequency Space (OTFS) modulation has been recently proposed to be robust to channel induced Doppler shift in high mobility wireless communication systems.

First-Principles View on Photoelectrochemistry: Water-Splitting as Case Study
Inorganics, 2017 Photoelectrochemistry is truly an interdisciplinary field; a natural nexus between chemistry and physics. In short, photoelectrochemistry can be divided into three sub-processes, namely (i) the creation of electron-hole pairs by light absorption; (ii ...

A Libertarian Anarchist Analysis of Norman Geisler’s Philosophy of Government
Religions, 2023 There are numerous approaches and conclusions regarding church and state relations and how Christianity affects public policy. Yet the purpose of this study is to question some of the philosophical assumptions and biblical interpretations that Christians

A First-Principles Study of Zinc Oxide Honeycomb Structures [PDF]
, 2009 We present a first-principles study of the atomic, electronic, and magnetic properties of two-dimensional (2D), single and bilayer ZnO in honeycomb structure and its armchair and zigzag nanoribbons.
