On the degenerate negative λ-binomial and Poisson random variables from degenerate special polynomials

open access: yesMathematical and Computer Modelling of Dynamical Systems
In this paper, we investigate the theory and applications of negative λ-binomial random variable with parameter [Formula: see text] and Poisson random variable with parameter [Formula: see text].

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.

Surgery in patients aged ≥ 80 years: mortality and recovery in a nationwide cohort study*

open access: yesAnaesthesia, Volume 80, Issue 7, Page 812-822, July 2025.
Summary Introduction As the global population ages, the demand for surgical interventions in older adults is rising. Older patients face increased risks due to age‐related physiological changes and comorbidities, making surgery and postoperative care challenging.

On central complete Bell polynomials

open access: yes, 2018
In this paper, we consider central complete and incomplete Bell polynomials which are generalizations of the recently introduced central Bell polynomials and central analogues for the complete and incomplete Bell polynomials. We investigate some properties and identities for these polynomials.

Multi‐Species Impacts of Invasive Opuntia Cacti on Mammal Habitat Use

open access: yesEcology Letters, Volume 28, Issue 7, July 2025.
Biological invasions impact ecosystems worldwide, including through changing the behaviour of native species. Here, we used camera traps to investigate the effects of invasive Opuntia spp. on the habitat use of 12 mammal species in an internationally important region of mammalian biodiversity.
