Spreading in claw-free cubic graphs [PDF]
Opuscula MathematicaLet \(p \in \mathbb{N}\) and \(q \in \mathbb{N} \cup \lbrace \infty \rbrace\). We study a dynamic coloring of the vertices of a graph \(G\) that starts with an initial subset \(S\) of blue vertices, with all remaining vertices colored white.

Throttling positive semidefinite zero forcing propagation time on graphs [PDF]
, 2018 Zero forcing is a process on a graph that colors vertices blue by starting with some of the vertices blue and applying a color change rule. Throttling minimizes the sum of the size of the initial blue vertex set and the number of the time steps needed to

Thermal-hydraulic 0D/3D coupling in OpenFOAM: Validation and application in nuclear installations
Nuclear Engineering and Technology, 2023 The nuclear safety assessment involving large transient simulations is forcing the community to develop methods for coupling thermal-hydraulics and neutronic codes and three-dimensional (3D) Computational Fluid Dynamics (CFD) codes.

Zero Forcing Sets for Graphs [PDF]
, 2013 For any simple graph $G$ on $n$ vertices, the (positive semi-definite) minimum rank of $G$ is defined to be the smallest possible rank among all (positive semi-definite) real symmetric $n\times n$ matrices whose entry in position $(i,j)$, for $i\neq j$, is non-zero if $ij$ is an edge in $G$ and zero otherwise. Also, the (positive semi-definite) maximum

Periodic perturbations of constrained motion problems on a class of implicitly defined manifolds [PDF]
, 2014 We study forced oscillations on differentiable manifolds which are globally defined as the zero set of appropriate smooth maps in some Euclidean spaces.

Crystalline evolutions with rapidly oscillating forcing terms [PDF]
, 2017 We consider the evolution by crystalline curvature of a planar set in a stratified medium, modeled by a periodic forcing term. We characterize the limit evolution law as the period of the oscillations tends to zero.

Monitoring of water and carbon fluxes using a land data assimilation system: a case study for southwestern France [PDF]
Hydrology and Earth System Sciences, 2010 A Land Data Assimilation System (LDAS) able to ingest surface soil moisture (SSM) and Leaf Area Index (LAI) observations is tested at local scale to increase prediction accuracy for water and carbon fluxes.

Grundy dominating sequences and zero forcing sets
Discrete Optimization, 2017 In a graph $G$ a sequence $v_1,v_2,\dots,v_m$ of vertices is Grundy dominating if for all $2\le i \le m$ we have $N[v_i]\not\subseteq \cup_{j=1}^{i-1}N[v_j]$ and is Grundy total dominating if for all $2\le i \le m$ we have $N(v_i)\not\subseteq \cup_{j=1}^{i-1}N(v_j)$.

Simulated enhancement of ENSO-related rainfall variability due to Australian dust [PDF]
Atmospheric Chemistry and Physics, 2011 Australian dust emissions are highly episodic, and this may increase the importance of Australian dust as a climate feedback agent. We compare two 160-year coupled atmosphere-ocean simulations of modern-day climate using the CSIRO Mark 3.6 global climate

Universally measurable sets in generic extensions [PDF]
, 2009 A subset of a topological space is said to be \emph{universally measurable} if it is measured by the completion of each countably additive $\sigma$-finite Borel measure on the space, and \emph{universally null} if it has measure zero for each such ...
