Value Sharing and Stirling Numbers

open access: yesComputational Methods and Function Theory
Let $f$ be an entire function and $L(f)$ a linear differential polynomial in $f$ with constant coefficients. Suppose that $f$, $f'$, and $L(f)$ share a meromorphic function $\alpha(z)$ that is a small function with respect to $f$. A characterization of the possibilities that may arise was recently obtained by Lahiri.

Test results of a Stirling engine utilizing heat exchanger modules with an integral heat pipe [PDF]

open access: yes
The Heat Pipe Stirling Engine (HP-1000), a free-piston Stirling engine incorporating three heat exchanger modules, each having a sodium filled heat pipe, has been tested at the NASA-Lewis Research Center as part of the Civil Space Technology Initiative ...

Designing Stable Graphitic Networks on Ultra‐Porous Polyimide Aerogels via Solvent‐Guided Structuring

open access: yesSmall, EarlyView.
A thermally robust, hierarchically porous polyimide aerogel is engineered via solvent‐polymer interaction tuning to enable stable laser‐induced graphitization. The resulting graphene‐integrated structure exhibits low resistivity, excellent dielectric performance, and thermal insulation, supporting applications in flexible electronics, thermal ...

Maximizing the detection probabilities of dusky grouse for population monitoring

open access: yesWildlife Biology, EarlyView.
Despite its status as a game species in the western USA, rigorous monitoring of dusky grouse Dendragapus obscurus populations is limited. Obtaining an adequate number of observations for effective population monitoring of dusky grouse is challenging due to difficult‐to‐reach montane habitats, cryptic behaviors, and limited personnel, time, and funds at

Exploring probabilistic Bernstein polynomials: identities and applications

open access: yesApplied Mathematics in Science and Engineering
In this paper, we introduce the probabilistic Bernstein polynomials and derive new and interesting correlations among several special functions and special number sequences such as Euler polynomials, Bernoulli polynomials of higher order, Frobenius–Euler

Euler-Mahonian Statistics On Ordered Set Partitions (II)

open access: yes, 2007
We study statistics on ordered set partitions whose generating functions are related to $p,q$-Stirling numbers of the second kind. The main purpose of this paper is to provide bijective proofs of all the conjectures of \stein (Arxiv:math.CO/0605670). Our

Passive acoustic monitoring with AI‐based detection and identification reveal sooty grouse hooting patterns in western Oregon

open access: yesWildlife Biology, EarlyView.
Many bird species are monitored using auditory point count surveys during the breeding season. Autonomous recording units (ARUs) can be used to better understand the daily and seasonal timing of when a species is vocalizing, which can help align surveys with the time period when the maximum number of individuals are present. We used ARUs to improve our

Heat engines for scale invariant systems dual to black holes

open access: yesCommunications Physics
According to holography, a black hole is dual to a thermal state in a strongly coupled quantum system. One of the best-known examples of holography is the Anti-de Sitter/Conformal Field Theory (AdS/CFT) correspondence.

From Pirates to Professionals: Retaining a Sense of Integration During Venture Scaling

open access: yesBritish Journal of Management, EarlyView.
Abstract Our paper explains how organizations can build and sustain internal member identification during rapidly scaling transitions. Using a longitudinal case study of a UK scaling firm, we show how organizational members follow a recursive process of retaining and forgoing the past and foreseeing the future to create a transitional organizational ...
