The Influence of Interior Structure and Thermal State on Impact Melt Generation Upon Large Impacts Onto Terrestrial Planets

open access: yesJournal of Geophysical Research: Planets, Volume 130, Issue 7, July 2025.
Abstract We investigate the melt production of planetary impacts as a function of planet size (R/REarth $R/{R}_{\text{Earth}}$ = 0.1–1.5), impactor size (L $L$ = 1–1,000 km), and core size ratio (Rcore/R ${R}_{\text{core}}/R$ = 0.2–0.8) using a combination of parameterized convection models and fully dynamical 2D impact simulations.

Feral horses at the city gate: ecological insights and rewilding opportunity

open access: yesThe Journal of Wildlife Management, Volume 89, Issue 4, May 2025.
Using motion‐sensitive cameras, we monitored the spatial and temporal distribution of the feral horse population in the La Calvana Natura 2000 site in central Italy. We estimated that the population was growing and horses were present in 40% of the sampled area.

Fractional Crystallization Scenario for Magma Evolution on Mercury Inferred From Geochemical Variation Around the Caloris Basin

open access: yesJournal of Geophysical Research: Planets, Volume 130, Issue 4, April 2025.
Abstract The observed geochemical heterogeneity on the surface of Mercury is key to understanding the planet's volcanic activity and mantle conditions. The Caloris basin shows a diversity in elemental composition, spectral properties, and geomorphology, both within and around it.

Therapeutic Potential of Saffron Extract in Mild Depression: A Study of Its Role on Anhedonia in Rats and Humans

open access: yesPhytotherapy Research, Volume 39, Issue 3, Page 1277-1291, March 2025.
ABSTRACT Drugs generally used in major depressive disorder are considered inappropriate for the more common milder forms. The efficacy of saffron extracts has been demonstrated in mild to moderate depression and in preclinical models of depression. However, evidence of saffron activity on reduced hedonic responsiveness and motivational anhedonia is ...

Cross‐pathway integration of cAMP signals through cGMP and calcium‐regulated phosphodiesterases in mouse striatal cholinergic interneurons

open access: yesBritish Journal of Pharmacology, Volume 182, Issue 5, Page 1236-1253, March 2025.
Abstract Background and Purpose Acetylcholine plays a key role in striatal function. Firing properties of striatal cholinergic interneurons depend on intracellular cAMP through the regulation of Ih currents. Yet, the dynamics of cyclic nucleotide signalling in these neurons have remained elusive.

A NEW GENERALIZATION OF THE PADOVAN SEQUENCE

open access: yes, 2022
Integers number sequences in mathematics are one of the subjects with the most ap- plication area. The Fibonacci number sequence has applications in many branches of science such as nature, anatomy, botany, zoology, art, music, analysis, physics, astronomy, chemistry, biology and computers.

Urbanized stream restoration as designed adaptation: Planning using synthetic digital rivers and form variation assessment

open access: yesRiver Research and Applications, Volume 41, Issue 2, Page 268-284, February 2025.
Abstract Restoring urbanized streams is challenging because of the absence of natural reference reaches and major changes in discharge and sediment supply as a consequence of catchment urbanization. In many cases the risk to urban infrastructure leads to form‐based restoration with less opportunity for process‐based approaches.

Some Properties of Padovan Sequence by Matrix Methods.

open access: yesArs Comb., 2012
It is the aim of this paper to explore some new properties of the Padovan sequence using matrix methods. We derive new recurrence relations and generating matrices for the sums of Padovan numbers and 4n subscripted Padovan sequences. Also, we define one type of (0,1) upper Hessenberg matrix whose permanents are Padovan numbers.
