Asymptotic estimates of the difference of products of Bessel functions by the integral of these functions

open access: yesVestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2020
In the study of direct and inverse problems of finding the right-hand side of degenerate equations of mixed type with different boundary conditions, the problem arises of establishing asymptotic estimates for the differences of the products of ...

Separating the Costs and Benefits of Employee Turnover: A Theory‐Driven Method and Applications

open access: yesIndustrial Relations: A Journal of Economy and Society, EarlyView.
ABSTRACT Employee turnover is costly, but it may also benefit performance through improving job‐worker match quality. Existing studies estimate only the net turnover‐performance relationship, ignoring benefits and biasing cost estimates. We develop a theory‐driven method that separately identifies operational costs and match‐quality benefits of ...

Contractions of 2D 2nd Order Quantum Superintegrable Systems and the Askey Scheme for Hypergeometric Orthogonal Polynomials [PDF]

open access: yes, 2013
We show explicitly that all 2nd order superintegrable systems in 2 dimensions are limiting cases of a single system: the generic 3-parameter potential on the 2-sphere, S9 in our listing.

The host range paradox of Meloidogyne incognita: a physiological and transcriptomic analysis of nine susceptible interactions across six plant orders

open access: yesNew Phytologist, EarlyView.
Phylogenetic distance of host does not explain phenotypic differences of Meloidogyne incognita parasitism at 25 dpi. Summary The plant–parasitic nematode Meloidogyne incognita is the pathogen with the broadest host range among all known biotrophic interactions.

Dark diversity of flea (Siphonaptera) assemblages in South American rodents: Latitudinal and altitudinal gradients

open access: yesEcological Entomology, Volume 51, Issue 5, Page 983-992, October 2026.
The dark diversity of compound flea communities increased from north to south. The dark diversity of compound flea communities increased from lower to higher altitudes. The dark diversity of component flea communities also increased from north to south but did not vary with altitude.

Polytope symmetries of Feynman integrals

open access: yesPhysics Letters B
Feynman integrals appropriately generalized are A-hypergeometric functions. Among the properties of A-hypergeometric functions are symmetries associated with the Newton polytope.

A Stochastic Approach for Recovery Times of Coastal Dune Vegetation

open access: yesGeophysical Research Letters, Volume 53, Issue 17, 16 September 2026.
Abstract The resilience of coastal dunes to environmental stress largely depends on vegetation recovery, which promotes sediment trapping and sand stabilization. However, post‐disturbance recovery dynamics remain difficult to quantify due to the complex interplay between biotic and abiotic processes.

HLA‐DR+ Schwann Cells Generate the Protumor Cancer‐Neuron‐Immune Niche in Head and Neck Squamous Cell Carcinoma

open access: yesAdvanced Science, Volume 13, Issue 51, 14 September 2026.
Hijacked and educated by HNSCC cells, HLA‐DR+ Schwann cells lost their normal neural‐related functions but acquired immunoregulatory phenotypes to promote CD4+ T cells transform into Tregs. HLA‐DR+ Schwann cells induced a macrophage subpopulation, Il1β.
