High-Energy String Scattering Amplitudes and Signless Stirling Number Identity
Symmetry, Integrability and Geometry: Methods and Applications, 2012 We give a complete proof of a set of identities (7) proposed recently from calculation of high-energy string scattering amplitudes. These identities allow one to extract ratios among high-energy string scattering amplitudes in the fixed angle regime from

Bell Numbers of Complete Multipartite Graphs [PDF]
Computer Science Journal of Moldova, 2016 The {\it Stirling number} $S(G;k)$ is the number of partitions of the vertices of a graph $G$ into $k$ nonempty independent sets and the number of all partitions of $G$ is its {\it Bell number}, $B(G)$.

Energy Science & Engineering, 2021 In a numerical analysis of a Stirling engine, the thermal and flow fields in the cylinder are three‐dimensional and periodically varying. Therefore, a computational fluid dynamic (CFD) analysis may provide detailed solution but it takes a long ...

Block patterns in Stirling permutations [PDF]
, 2014 We introduce and study a new notion of patterns in Stirling and $k$-Stirling permutations, which we call block patterns. We prove a general result which allows us to compute generating functions for the occurrences of various block patterns in terms of ...

British 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 ...

Diet of bird‐like troodontid dinosaurs: synthesis of a contentious clade
Biological Reviews, EarlyView.ABSTRACT Troodontidae is a clade of small‐to medium‐sized maniraptoran theropods that mainly lived in Laurasia (modern Asia, North America and Europe) during the Jurassic and Cretaceous periods and are believed to have had a variety of diets. The uniqueness of troodontid teeth suggests that they diverged from the typical flesh‐based diet of non‐avian ...

Lagrange inversion and Stirling number convolutions [PDF]
, 2014 Recently Agoh and Dilcher proved a convolution identity involving Stirling numbers S(n, r) of the second kind. We prove an identity where S(n, r) is replaced by a more general doubly-indexed family A(n, r).

Divisibility by 2 and 3 of certain Stirling numbers
, 2008 The numbers e_p(k,n) defined as min(nu_p(S(k,j)j!): j >= n) appear frequently in algebraic topology. Here S(k,j) is the Stirling number of the second kind, and nu_p(-) the exponent of p. The author and Sun proved that if L is sufficiently large, then e_p(
