Total Roman domination in graphs
Applicable Analysis and Discrete Mathematics, 2016 A Roman dominating function on a graph G is a function f:V(G) → {0,1,2} satisfying the condition that every vertex u for which f(u) = 0 is adjacent to at least one vertex v for which f(v) = 2. The weight of a Roman dominating function f is the sum, ΣuV(G) f(u), of the weights of the vertices.

European Policy Analysis, EarlyView.Abstract This article applies the concept of transaction to the process of policy transfer, through the case of conflict of interest regulation in France, using archives, documentary sources, and interviews with stakeholders. It contributes to the literature on policy translation by clarifying the role of contingency, which remains underspecified.

European Policy Analysis, EarlyView.Abstract This paper presents a methodological framework to study situated and relational policy practices in the context of the policy transaction perspective. Building on policy ethnography, it addresses the entanglements of researching policy transactions through triangulation of methods to explore how practices emerge, and how they are “seen ...

Parametric Study on the Performance of Gas Springs in FPSE With Pneumatic Supporting System
Energy Science &Engineering, EarlyView.ABSTRACT The introduction of a pneumatic supporting system composed of gas springs and hydrostatic bearings in the free‐piston Stirling generator (FPSG) can effectively increase the power density of the nuclear space power plant. In this paper, a 1 kW FPSG with pneumatic supporting system was developed, and the working characteristics of dual gas ...

Ecological and developmental history impacts the equitable distribution of services
Frontiers in Ecology and the Environment, EarlyView.The ecological and developmental history of the Chicago, Illinois, region has affected the current distribution of forests therein. These same factors, along with systemic and long‐lasting racial segregation, have shaped the distribution of the urban populations that benefit from the ecosystem services provided by urban forests. This study demonstrates
