Towards the Centenary of Sheffer Polynomial Sequences: Old and Recent Results

open access: yesMathematics, 2022
Sheffer’s work is about to turn 100 years after its publication. In reporting this important event, we recall some interesting old and recent results, aware of the incompleteness of the wide existing literature. Particularly, we recall Sheffer’s approach,

How Framing of Income Eligibility Guidelines Affect Attitudes Towards Program Access and Burdens in Health and Health‐Protective Programs

open access: yesWorld Medical &Health Policy, Volume 17, Issue 4, Page 898-911, December 2025.
ABSTRACT Policymakers organize and frequently communicate safety net policies, such as eligibility guidelines around administrative categories. The potential effects on how these thresholds are communicated remain empirically unexplored. We examined if communication either in terms of the Federal Poverty Line (FPL)‐ or dollar‐form alters preferences ...

Some Identities on Degenerate Bernstein and Degenerate Euler Polynomials

open access: yesMathematics, 2019
In recent years, intensive studies on degenerate versions of various special numbers and polynomials have been done by means of generating functions, combinatorial methods, umbral calculus, p-adic analysis and differential equations.

Bell-Based Bernoulli Polynomials with Applications

open access: yesAxioms, 2021
In this paper, we consider Bell-based Stirling polynomials of the second kind and derive some useful relations and properties including some summation formulas related to the Bell polynomials and Stirling numbers of the second kind.

Threshold responses of floating meadow fish communities to floodplain forest cover in the lower Amazon River

open access: yesConservation Biology, Volume 39, Issue 6, December 2025.
Abstract Forest cover is positively associated with fish biomass and fisheries yield in the Amazon River floodplain, and many species enter flooded forests to feed, spawn, or seek refuge from predation. Floating macrophyte beds, known as floating meadows, in Amazon floodplains support high fish diversity and serve as nursery habitat for many fishes of ...

Managing Risk, Reinforcing Environmental Racism: The Biopolitics of Pesticide Regulation in California Agriculture

open access: yesReview of Policy Research, Volume 42, Issue 6, Page 1509-1524, November 2025.
ABSTRACT This paper provides a retrospective on California's oversight of 1,3‐dichloropropene (1,3‐D). It utilizes archival documents, including internal memos, emails, and risk assessments, to demonstrate how the state's Department of Pesticide Regulation consistently expanded allowable 1,3‐D use while presenting each policy change as scientifically ...

Taxon‐specific BLAST percent identity thresholds for identification of unknown sequences using metabarcoding

open access: yesMethods in Ecology and Evolution, Volume 16, Issue 10, Page 2380-2394, October 2025.
Abstract The identification of organisms in environmental samples using metabarcoding relies on factors such as taxonomic assignment methods, genetic markers, reference databases and confidence thresholds for taxonomic assignment. Because lineages evolve at different rates, a global threshold (e.g.

Hermite Calculus [PDF]

open access: yes, 2017
We develop a new method of umbral nature to treat blocks of Her mite and of Hermite like poly- nomials as independent algebraic quantities. The Calculus we propose allows the formulation of a number of ”practical rules” allowing significant ...
