Entropy, 2019 Pressure ulcers are one of the most common complications of a spinal cord injury (SCI). Prolonged unrelieved pressure is thought to be the primary causative factor resulting in tissue ischemia and eventually pressure ulcers.

A regularity structure for rough volatility [PDF]
Mathematical Finance, 2017 A new paradigm has emerged recently in financial modeling: rough (stochastic) volatility. First observed by Gatheral et al. in high‐frequency data, subsequently derived within market microstructure models, rough volatility captures parsimoniously key ...

Nonlinear higher order fractional terminal value problems
AIMS Mathematics, 2022 Terminal value problems for systems of fractional differential equations are studied with an especial focus on higher-order systems. Discretized piecewise polynomial collocation methods are used for approximating the exact solution. This leads to solving

Local Elliptic Regularity for the Dirichlet Fractional Laplacian [PDF]
, 2017 We prove the Wloc2s,p${W_{{\mathrm{loc}}}^{2s,p}}$ local elliptic regularity of weak solutions to the Dirichlet problem associated with the fractional Laplacian on an arbitrary bounded open set of ℝN${\mathbb{R}^{N}}$. The key tool consists in analyzing

Regular graphs with regular neighborhoods [PDF]
Glasgow Mathematical Journal, 1992 The existence of r-regular graphs such that each edge lies in exactly t triangles, for given integers t < r, is studied. If t is sufficiently close to r then each such connected graph has to be the complete multipartite graph. Relations to graphs with isomorphic neighborhoods are also considered.

Regular subgraphs of almost regular graphs [PDF]
Journal of Combinatorial Theory, Series B, 1984 AbstractSuppose every vertex of a graph G has degree k or k + 1 and at least one vertex has degree k + 1. It is shown that if k ≥ 2q − 2 and q is a prime power then G contains a q-regular subgraph (and hence an r-regular subgraph for all r < q, r ≡ q (mod 2)). It is also proved that every simple graph with maximal degree Δ ≥ 2q − 2 and average degree d

Regular transducer expressions for regular transformations [PDF]
Information and Computation, 2018 Functional MSO transductions, deterministic two-way transducers, as well as streaming string transducers are all equivalent models for regular functions. In this paper, we show that every regular function, either on finite words or on infinite words, captured by a deterministic two-way transducer, can be described with a regular transducer expression ...

Le quotidien, objet philosophique ?
Cahiers Jean Moulin, 2019 Everyday life takes place between the two poles of the abstract and the concrete pushed one against the other. On the one hand, everyday life is made up of repetitive stereotypes, that their haunting return paradoxically makes invisible, so much do they ...

On fractional Schrödinger equations with Hartree type nonlinearities
Mathematics in Engineering, 2022 Goal of this paper is to study the following doubly nonlocal equation $(- \Delta)^s u + \mu u = (I_\alpha*F(u))F'(u) \quad {\rm{in}}\;{\mathbb{R}^N}\qquad\qquad\qquad\qquad ({\rm{P}}) $ in the case of general nonlinearities $ F \in C^1(\mathbb{R})

Regularity and Planarity of Token Graphs
Discussiones Mathematicae Graph Theory, 2017 Let G = (V, E) be a graph of order n and let 1 ≤ k < n be an integer. The k-token graph of G is the graph whose vertices are all the k-subsets of V, two of which are adjacent whenever their symmetric difference is a pair of adjacent vertices in G.
