Network Models from Petri Nets with Catalysts [PDF]
Compositionality, Volume 1 (2019) (December 25, 2019)
compositionality:13531, 2019 Petri networks and network models are two frameworks for the compositional design of systems of interacting entities. Here we show how to combine them using the concept of a "catalyst": an entity that is neither destroyed nor created by any process it engages in.

eTropic: electronic journal of studies in the Tropics, 2016 Cyclones are endured, but often dreaded in tropical regions such as Far North Queensland. Memories, and often myth, of their destructive effects permeate written, visual and spoken text from and about this area. This paper presents findings from a qualitative research project which examined the impact of tropical north Queensland’s 2006 Cyclone Larry ...

Diffusion and catalyst efficiency in hierarchical zeolite catalysts
National Science Review, 2020 Abstract The preparation of hierarchical zeolites with reduced diffusion limitation and enhanced catalyst efficiency has become a vital focus in the field of zeolites and porous materials chemistry within the past decades. This review will focus on the diffusion and catalyst efficiency of hierarchical zeolites and industrial catalysts ...

Amplifying asymmetry with correlated catalysts [PDF]
Phys. Rev. A 103, 022403 (2021), 2020 We investigate the basic constraint on amplifying the asymmetry in quantum states with correlated catalysts. Here a correlated catalyst is a finite-dimensional auxiliary, which exactly preserves its reduced state while allowed to become correlated to the quantum system.

Catalyst-assisted Probabilistic Entanglement Transformation [PDF]
IEEE Trans. Inform. Theory, Vol. 51, No. 3, pp. 1090-1101, Mar.
(2005), 2004 We are concerned with catalyst-assisted probabilistic entanglement transformations. A necessary and sufficient condition is presented under which there exist partial catalysts that can increase the maximal transforming probability of a given entanglement transformation. We also design an algorithm which leads to an efficient method for finding the most

Integration as a catalyst for assimilation [PDF]
International Review of Economics & Finance, 2013 We draw a distinction between the social integration and economic assimilation of migrants, and study an interaction between the two. We define social integration as blending into the host country’s society, and economic assimilation as acquisition of human capital that is specific to the host country’s labor market.

Spatial Structure Engineering in Enhancing Performance of Mosaic Electrocatalysts [PDF]
arXiv, 2021 Understanding the mechanism and developing strategies toward efficient electrocatalysis at gas-liquidsolid interfaces are important yet challenging. In the past decades, researchers have devoted many efforts to improving catalyst activity by modulating electronic properties of catalysts in terms of chemical components and physical features.

Near critical catalyst reactant branching processes with controlled immigration [PDF]
Annals of Applied Probability 2013, Vol. 23, No. 5, 2053-2098, 2012 Near critical catalyst-reactant branching processes with controlled immigration are studied. The reactant population evolves according to a branching process whose branching rate is proportional to the total mass of the catalyst. The bulk catalyst evolution is that of a classical continuous time branching process; in addition there is a specific form ...

Catalyst preparation for CMOS-compatible silicon nanowire synthesis [PDF]
Nature Nanotechnology 4 (2009) 654-657, 2010 Metallic contamination was key to the discovery of semiconductor nanowires, but today it stands in the way of their adoption by the semiconductor industry. This is because many of the metallic catalysts required for nanowire growth are not compatible with standard CMOS (complementary metal oxide semiconductor) fabrication processes.
