Bateman gradients from first principles

open access: yesNature 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.

Electronic and geometric stability of double titanium-doped silicon clusters

open access: yesMaterials Research Express, 2020
We performed the genetic algorithm (GA) incorporated with density functional theory (DFT) calculations to investigate the atomic and electronic properties of a series of Ti _2 Si _n (n = 3 = –24) clusters.

First Principles, Fallibilism, and Economics [PDF]

open access: yesSSRN Electronic Journal, 2017
In the eyes of its practitioners, economics is both a deductive science and an empirical science. The starting point of its deductions might be thought of as first principles. But what is the status of such principles? The tension between foundationalism, the idea that there are necessary and secure first principles for economic inquiry, and ...

First-principles calculations for attosecond electron dynamics in solids

open access: yes, 2020
Nonequilibrium electron dynamics in solids is an important subject from both fundamental and technological points of view. The recent development of laser technology has enabled us to study ultrafast electron dynamics in the time domain. First-principles

First-Principles View on Photoelectrochemistry: Water-Splitting as Case Study

open access: yesInorganics, 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 ...

Metal-Ions Intercalation Mechanism in Layered Anode From First-Principles Calculation

open access: yesFrontiers in Chemistry, 2021
Layered structure (MoS2) has the potential use as an anode in metal-ions (M-ions) batteries. Here, first-principles calculations are used to systematically investigate the diffusion mechanisms and structural changes of MoS2 as anode in lithium (Li ...

Agentic Finance: An Adaptive Inference Framework for Bounded-Rational Investing Agents

open access: yesEntropy
We propose Adaptive Inference, a portfolio management framework extending Active Inference to non-stationary financial environments. The framework integrates inference, control, and execution under endogenous uncertainty, modeling investment decisions as

First-principles investigation of phase stability and elastic properties of Laves phase TaCr2 by ruthenium alloying

open access: yesHigh Temperature Materials and Processes, 2023
Based on the first-principles method of density functional theory, the microscopic mechanism of the effect of addition of alloying element Ru content on the stability and elastic properties of Laves phase TaCr2 was investigated by parameters such as ...
