Stabilized conforming nodal integration: Exactness and variational justification [PDF]
Finite Elements in Analysis and Design, 2004 In most Galerkin mesh-free methods, background integration cells partitioning the problem domain are required to evaluate the weak form. It is therefore worthwhile to consider these methods using the notions of domain decomposition with the integration ...

Nodal integration of meshless methods [PDF]
, 2009 Meshless methods offer interesting properties for the simulation of bulk forming\ud processes. This research concerns the investigation of the stabilized conforming nodal integration scheme (SCNI) for use in metal-forming processes. Two tests are carried

Nodal prices in an integrated energy system [PDF]
International Journal of Critical Infrastructures, 2006 This paper presents a multiperiod generalised network flow model used to analyse the economic interdependencies of integrated energy systems comprising the electric network and the various fuel supply and delivery systems in a medium term operational time frame.

Nodal points and complexity of Notch-Ras signal integration [PDF]
Proceedings of the National Academy of Sciences, 2009 Metazoans use a handful of highly conserved signaling pathways to create a signaling backbone that governs development. How these few signals have such a versatile action likely depends upon the larger-scale network they form through integration, as exemplified by cross-talk between the Notch and receptor tyrosine kinase (RTK) pathways. We examined the

A New Stabilized Nodal Integration Approach [PDF]
, 2007 A new stabilized nodal integration scheme is proposed and implemented. In this work, focus is on the natural neighbor meshless interpolation schemes. The approach is a modification of the stabilized conforming nodal integration (SCNI) scheme and is shown to perform well in several benchmark problems.

A volume-averaged nodal projection method for the Reissner-Mindlin plate model [PDF]
, 2018 We introduce a novel meshfree Galerkin method for the solution of Reissner-Mindlin plate problems that is written in terms of the primitive variables only (i.e., rotations and transverse displacement) and is devoid of shear-locking. The proposed approach

The TDNNS method for Reissner-Mindlin plates [PDF]
, 2017 A new family of locking-free finite elements for shear deformable Reissner-Mindlin plates is presented. The elements are based on the "tangential-displacement normal-normal-stress" formulation of elasticity.

The ALE-method with triangular elements: direct convection of integration point values [PDF]
, 2000 The arbitrary Lagrangian-Eulerian (ALE) finite element method is applied to the simulation of forming processes where material is highly deformed. Here, the split formulation is used: a Lagrangian step is done with an implicit finite element formulation,

Integration of Nodal and BMP Signaling by Mutual Signaling Effector Antagonism [PDF]
Cell Reports, 2020 Opposing sources of bone morphogenetic protein (BMP) and Nodal signaling molecules are sufficient to induce the formation of a full axis in zebrafish embryos. To address how these signals orchestrate patterning, we transplant sources of fluorescently tagged Nodal and BMP into zebrafish embryos, robustly inducing the formation of secondary axes.
