Spatio‐temporal dynamics of ringed seal density and habitat use in the Arctic's Last Ice Area

Ecography, EarlyView.
The Arctic is warming at approximately four times the global rate, driving widespread decline in sea ice extent, thickness, and seasonal duration. The ecological consequences of these rapid changes remain poorly understood within the Last Ice Area, a region that includes northern Ellesmere Island and the northwest of Greenland, projected to retain ...

Heterogeneous r-Stirling numbers via boson operators

Open Physics
This paper investigates the properties and operator-theoretic representations of the heterogeneous r-Stirling numbers of the first and second kind. Building upon the recent introduction of heterogeneous Stirling sequences, we extend these concepts to the

New conditions for Pascal distribution series to be in a certain class of analytic functions

Heliyon
Studies of Sălăgean differential operator Dκ in connection with Stirling numbers are relatively new. In this paper, the differential operator Dκ involving Stirling numbers is considered.

Generalized Stirling numbers with poly-Bernoulli and poly-Cauchy numbers

, 2018
By using the generalized Stirling numbers studied by Hsu and Shiue, we define a new kind of generalized poly-Bernoulli and poly-Cauchy numbers. By using the formulae of the generalized Stirling numbers, we give their characteristic and combinatorial ...

Associations between mycorrhizal dominance and woody species diversity shift with stand development and climate across subtropical and tropical forests in Taiwan

Ecography, EarlyView.
Mycorrhizal symbioses influence woody species diversity, but whether this association shifts with forest stand development remains underexplored. Using forest inventory data across subtropical and tropical forests in Taiwan, we found that woody species diversity was lower in ectomycorrhizal (EM)‐dominated than in arbuscular mycorrhizal (AM)‐dominated ...

Identities, inequalities for Boole-type polynomials: approach to generating functions and infinite series

Journal of Inequalities and Applications, 2019
The main purpose and motivation of this work is to investigate and provide some new identities, inequalities and relations for combinatorial numbers and polynomials, and for Peters type polynomials with the help of their generating functions. The results

The D-Stirling Numbers

, 2008
In this paper, we introduce a kind of combinatorial numbers, D − Stirling numbers, and its special cases. An exponential generating function of the D − Stirling numbers is given. We also present recurrence relations, monotonicity, and limiting properties

Seizure forecasting: The long and winding road to clinical translation

Epilepsia, EarlyView.
Abstract Seizure forecasting has progressed from theoretical aspiration to a rapidly advancing research domain, yet clinical translation remains limited. Over the past decades, advances in algorithm development, chronic electroencephalography (EEG), wearable sensors, and the characterization of seizure cycles have demonstrated that seizure risk is not ...

Closed formulas for special bell polynomials by Stirling numbers and associate Stirling numbers

Publications de l'Institut Mathematique, 2020
We derive two explicit formulas for two sequences of special values of the Bell polynomials of the second kind in terms of associate Stirling numbers of the second kind, give an explicit formula for associate Stirling numbers of the second kind in terms of the Stirling numbers of the second kind, and, consequently, present two explicit ...

Monthly or menstrual? A scoping review of catamenial epilepsy and non‐menstrual seizure rhythms

Epilepsia, EarlyView.
Abstract Objective Despite the reported high prevalence of catamenial epilepsy (CE), the condition remains poorly defined, with lack of consensus on what entails a menstrual‐related seizure exacerbation. Emerging evidence of multiday cycles of seizure activity, including about‐monthly cycles, present in both men and women, further confound the ...
