Self‐Similar Blowup for the Cubic Schrödinger Equation
Communications on Pure and Applied Mathematics, EarlyView.ABSTRACT We give a rigorous proof for the existence of a finite‐energy, self‐similar solution to the focusing cubic Schrödinger equation in three spatial dimensions. The proof is computer‐assisted and relies on a fixed point argument that shows the existence of a solution in the vicinity of a numerically constructed approximation.

Multi-fixed smeared 3d crack model to simulate the behavior of fiber reinforced concrete structures [PDF]
, 2008 When a concrete structure is subjected to a multi-stress state, different crack modes can be developed. To simulate with enough accuracy these fracture modes, a three dimensional model must be used.

Invariant Measure and Universality of the 2D Yang–Mills Langevin Dynamic
Communications on Pure and Applied Mathematics, EarlyView.ABSTRACT We prove that the Yang–Mills (YM) measure for the trivial principal bundle over the two‐dimensional torus, with any connected, compact structure group, is invariant for the associated renormalised Langevin dynamic. Our argument relies on a combination of regularity structures, lattice gauge‐fixing and Bourgain's method for invariant measures ...

Corporate Social Responsibility and Environmental Management, EarlyView.ABSTRACT Mining is one of the foundations of economic development but has historically been associated with severe socioenvironmental impacts, such as ecosystem degradation, displacement of traditional communities, and large‐scale disasters. In this context, corporate social responsibility (CSR) plays a central role as a mechanism for legitimizing ...

IET Networks, EarlyView., 2022 Abstract This research aims to study the intelligent wireless sensor to improve the water permeability of permeable asphalt concrete pavement. The water permeability of pavement is extremely important for the traffic environment. This study first briefly introduces the background and significance analysis, and then exemplifies the deployment algorithm ...

Corporate Social Responsibility and Environmental Management, EarlyView.ABSTRACT Despite rapid growth in gender lens investing (GLI), substantial variation remains in how gender lens equity funds (GLEFs) integrate gender equality criteria into investment strategies. We map a universe of 43 GLEFs and develop a framework capturing gender equality screening breadth and accountability depth (fund‐level disclosure and ...

Development of self-compacting eco-concrete
, 2006 Ever since its introduction and increasingly widespread use since the early nineties, new mix design methods of Self-Compacting Concrete (SCC) can hardly be recognized. Despite intensive research and a substantial number of publications in this new technology the design concept still mainly follows the so-called "Japanese method" introduced by Okamura /
