Truncated Fubini Polynomials

open access: yesMathematics, 2019
In this paper, we introduce the two-variable truncated Fubini polynomials and numbers and then investigate many relations and formulas for these polynomials and numbers, including summation formulas, recurrence relations, and the derivative property.

Heat‐to‐Electricity Conversion Using Barium Strontium Titanate Multilayer Capacitors

open access: yesAdvanced Science, EarlyView.
Lead‐free barium strontium titanate multilayer capacitors convert waste heat into electricity via the Olsen electro‐thermodynamic cycle. These capacitors achieve an energy density of 3.7 J cm−3, comparable to the performance of lead‐based ceramics. Their high dielectric strength and broad operating temperature window below 100°C make them practical for

Multisectioned moments of stirling numbers of the second kind

open access: yesJournal of Combinatorial Theory, Series A, 1973
The Stirling number of the second kind, S(n, k), enumerates the ways that n distinct objects can be stored in k non-empty indistinguishable boxes. When k is restricted to a given residue class modulo μ, the moments of the distribution S(n, k) have properties associated with the Olivier functions of order μ evaluated at 1 and −1. The simplest example is

On the Uniqueness Conjecture for the Maximum Stirling Numbers of the Second Kind

open access: yesResults in Mathematics, 2021
The Stirling numbers of the second kind S(n,  k) satisfy S(n, 0)<¿<S(n, kn)=S(n, kn+1)>¿>S(n, n).A long standing conjecture asserts that there exists no n= 3 such that S(n, kn) = S(n, kn+ 1). In this note, we give a characterization of this conjecture in terms of multinomial probabilities, as well as sufficient conditions on n ensuring that

One‐Step Electrodeposition of Iron Oxyhydroxide Onto 3D Porous Graphene Substrates for on Chip Asymmetric Micro‐Supercapacitors

open access: yesBatteries &Supercaps, Volume 8, Issue 3, March 2025.
A micro‐supercapacitor with electrodeposited iron oxyhydroxide (FeOOH) as the negative electrode and birnessite manganese oxide (MnO2) as the positive electrode achieves a 2 V working voltage, stable cycling in an aqueous electrolyte, and high energy and power densities of 21 μWh cm‐2 and 2.5 mW cm‐2 respectively.

Measuring what matters: Evaluating the impact of curriculum decolonisation initiatives in UK business schools

open access: yesBritish Educational Research Journal, EarlyView.
Abstract Curriculum decolonisation has become a prominent feature of equity agendas in UK higher education, yet there remains limited empirical and theoretical work on how such initiatives are evaluated, particularly within business schools. This paper presents one of the first multi‐institutional empirical studies examining how UK business schools ...

Probabilistic multi-Stirling numbers of the second kind associated with random variables

open access: yesApplied Mathematics in Science and Engineering

THE 2-ADIC VALUATIONS OF STIRLING NUMBERS OF THE SECOND KIND [PDF]

open access: yesInternational Journal of Number Theory, 2012
In this paper, we investigate the 2-adic valuations of the Stirling numbers S(n, k) of the second kind. We show that v2(S(4i, 5)) = v2(S(4i + 3, 5)) if and only if i ≢ 7 (mod 32). This confirms a conjecture of Amdeberhan, Manna and Moll raised in 2008. We show also that v2(S(2n+ 1, k + 1)) = s2(n) - 1 for any positive integer n, where s2(n) is the sum ...
