Corinto: A Young, Extensively Rayed Crater That Produced a Billion Secondaries on Mars

open access: yesJournal of Geophysical Research: Planets, Volume 130, Issue 10, October 2025.
Abstract Corinto crater is a fresh, 13.9 km diameter impact crater in Elysium Planitia that produced one of the most extensive systems of thermally distinct rays and secondary craters on Mars, extending up to ∼2,000 km and covering a nearly 180° arc. It is the youngest crater of its size on Mars and impacted between 0.1 and 2.5 Ma into Early Amazonian ...

Lifecycle deficit and economic support ratio in Nigeria: The national transfer account approach

open access: yesJournal of Economics and Management
Aim/purpose – The benefit of changing the population age structure only accrues to an economy if the labor market absorbs the increasing number of the working population at a given labor income that surpasses the prevailing consumption of that age group.

Horizontal Fiscal Imbalance In The United States

open access: yesFolia Oeconomica Stetinensia, 2014
Regional inequalities are currently a challenge for the majority of countries, in particular large ones, certain of which are federations. The federal state system is more complex than the unitary system. This results in specific problems. One of them is

Cu─X Bonds Regulated Conduction and Polarization Loss in Conductive Metal‐Organic Framework Under Electromagnetic Field

open access: yesAdvanced Science, Volume 12, Issue 33, September 4, 2025.
A ligand regulation strategy by modifying functional motifs (X = −NH2, −OH, and −SH) in triphenylene is pioneered and developed to afford Cu─X bonds, achieving a synergistic conduction and polarisation loss mechanism under an electromagnetic field for enhanced electromagnetic wave absorption. Abstract Conduction and polarization are known to profoundly

Ab initio exploration of low‐lying electronic states of linear and bent MNX+ (M = Ca, Sr, Ba, Ra; X = O, S, Se, Te, Po) and their origins

open access: yesJournal of Computational Chemistry, Volume 45, Issue 30, Page 2530-2538, November 15, 2024.
Ab initio quantum calculations were performed to study electronic structures of linear‐MNX+ and side‐bonded‐M[NX]+ (M = Ca, Sr, Ba, Ra; X = O, S, Se, Te, Po) species. Their full potential energy curves, geometric parameters, and energy related properties are reported.

Composición de las exportaciones y crecimiento económico en la Comunidad Andina de Naciones

open access: yesLecturas de Economía, 2012
Este trabajo analiza la relación entre la composición de las exportaciones y el crecimiento económico. Partiendo de la estructura desarrollada por Feder (1983) y Crespo-Cuaresma y Wörz (2005), se desarrolla un modelo con datos de panel para el periodo ...
