Showcasing the Structure and Properties of Lanthanide‐Doped BaTiO3

open access: yesAdvanced Physics Research, Volume 4, Issue 9, September 2025.
Understanding the defect chemistry of Ln‐doped BTO, as well as the distribution of Ln ions inside the BTO host, is a challenge in the study of functional perovskite oxides. It provides important insights into the future development of Ln‐doped BTO materials, particularly in the context of low‐carbon transition strategies and renewable technologies that

Agent-based modelling. History, essence, future

open access: yesPSL Quarterly Review, 2017
The paper characterizes the currently fashionable modelling tool, agent-based simulation. First, it presents a selection of the major intellectual roots from which this new tool emerged. It is important for social scientists, in particular economists, to

Game-theory behaviour of large language models: The case of Keynesian beauty contests

open access: yesEconomics and Business Review
The growing adoption of large language models (LLMs) presents potential for deeper understanding of human behaviours within game theory frameworks. This paper examines strategic interactions among multiple types of LLM-based agents in a classical beauty ...

A model for $J/\psi$ - kaon cross section

open access: yes, 2003
We calculate the cross section for the dissociation of $J/\psi$ by kaons within the framework of a meson exchange model. We find that, depending on the values of the coupling constants used, the cross section can vary from 5 mb to 30 mb at $\sqrt{s}\sim5$

The Environment, Trade and Innovation with Heterogeneous Firms: A Numerical Analysis [PDF]

open access: yes
We employ a two-sector heterogeneous firms model in the presence of endogenous innovation and environmental constraints. We perform simple numerical simulations concerning the implication of a stringent environmental policy and trade cost differences ...

cis-Bis(azido-κN)bis(pyridine-2-carboxamide-κ2N1,O)nickel(II)

open access: yesActa Crystallographica Section E, 2008
The title compound, [Ni(N3)2(C6H6N2O)2], was obtained as the first crystalline product from the reaction of Ni(NO3)2·6H2O, picolinamide and NaN3 in aqueous media. After a few days in the mother liquor, crystals of the cis isomer transformed into the

Unfolding the Effects of the T=0 and T=1 Parts of the Two-Body Interaction on Nuclear Collectivity in the f-p Shell

open access: yes, 2005
Calculations of the spectra of various even-even nuclei in the fp shell ({44}Ti, {46}Ti, {48}Ti, {48}Cr and {50}Cr) are performed with two sets of two-body interaction matrix elements. The first set consists of the matrix elements of the FPD6 interaction.
