Comments on Joint Terms in Gravitational Action
, 2017 This paper compares three different methods about computing joint terms in on-shell action of gravity, which are identifying the joint term by the variational principle in Dirichlet boundary condition, treating the joint term as the limit contribution of

Business Strategy and the Environment, EarlyView.ABSTRACT Although recent literature on the circular economy (CE) has highlighted the important role of ecosystems, there is still limited understanding of the main themes that characterize circular ecosystems. This study addresses this gap by combining a comprehensive topic modeling analysis employing latent Dirichlet allocation (LDA) with a systematic

Particle Creation by a Moving Boundary with Robin Boundary Condition
, 2006 We consider a massless scalar field in 1+1 dimensions satisfying a Robin boundary condition (BC) at a non-relativistic moving boundary. We derive a Bogoliubov transformation between input and output bosonic field operators, which allows us to calculate ...

Harnessing Generative AI for Sustainable Supply Chains: Lean, Circular and Green Perspectives
Business Strategy and the Environment, EarlyView.ABSTRACT Generative artificial intelligence is playing a significant role in the transformation of digital ecosystems by reinventing the processes of content generation, process automation, product innovation and customer experience. At the same time that these technologies are becoming more integrated into routine operations, the focus has shifted to ...

The Nehari Manifold for p-Laplacian Equation with Dirichlet Boundary Condition
, 2007 . The Nehari manifold for the equation −∆pu(x) = λu(x)|u(x)| + b(x)|u(x)|u(x) for x ∈ Ω together with Dirichlet boundary condition is investigated in the case where 0 < γ < p.

Partial identification with categorical data and nonignorable missing outcomes
Canadian Journal of Statistics, EarlyView.Abstract Nonignorable missing outcomes are common in real‐world datasets and often require strong parametric assumptions to achieve identification. These assumptions can be implausible or untestable, and so we may wish to forgo them in favour of partially identified models that narrow the set of a priori possible values to an identification region.

Bayesian clustering of multivariate extremes
Canadian Journal of Statistics, EarlyView.Abstract The asymptotic dependence structure between multivariate extreme values is fully characterized by their projections on the unit simplex. Under mild conditions, the only constraint on the resulting distributions is that their marginal means must be equal, which results in a nonparametric model that can be difficult to use in applications ...

Degree theory for 4‐dimensional asymptotically conical gradient expanding solitons
Communications on Pure and Applied Mathematics, EarlyView.Abstract We develop a new degree theory for 4‐dimensional, asymptotically conical gradient expanding solitons. Our theory implies the existence of gradient expanding solitons that are asymptotic to any given cone over S3$S^3$ with non‐negative scalar curvature. We also obtain a similar existence result for cones whose link is diffeomorphic to S3/Γ$S^3/\

Existence and non-existence results for a nonlinear heat equation
Electronic Journal of Differential Equations, 2007 In this study, we consider the nonlinear heat equation $$displaylines{ u_{t}(x,t) = Delta u(x,t) + u(x,t)^p quad hbox{in } Omega imes (0,T),cr Bu(x,t) = 0 quad hbox{on } partialOmega imes (0,T),cr u(x,0) = u_0(x) quad hbox{in } Omega,}$$ with ...
