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 ...

Intrinsic properties and dopability effects on the thermoelectric performance of binary Sn chalcogenides from first principles

open access: yesFrontiers in Electronic Materials, 2022
High-performance thermoelectric (TE) materials rely on semiconductors with suitable intrinsic properties for which carrier concentrations can be controlled and optimized.

Lattice thermal conductivity of β-, α- and κ- Ga2O3: a first-principles computational study

open access: yesApplied Physics Express, 2023
The thermal transport properties of Ga _2 O _3 in different phases remain inadequately explored. We employ first-principles calculations and the phonon Boltzmann equation to systematically study the lattice thermal conductivity of β -, α - and κ -Ga _2 O

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 ...

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
