Ideal nodal-net, nodal-chain, and nodal-cage phonons in some realistic materials

Physical Chemistry Chemical Physics, 2022
We demonstrate the appearance of ideal nodal-net, nodal-chain, and nodal-cage phonons in these materials based on first-principle calculations.

Complexity of AV Nodal Function: Complex Nodal Structure or Complex Behavior of Nodal Elements?

Pacing and Clinical Electrophysiology, 1988
This paper discusses the hypothesis that the complex behavior of the atrioventricular (AV) node, with particular reference to Wenckebach periods, may be explained by the complexity of nodal structure and that complicated function of individual AV nodal fibers need not necessarily be considered.

Constant sign and nodal solutions for superlinear double phase problems

Advances in Calculus of Variations, 2019
We consider a double phase problems with unbalanced growth and a superlinear reaction, which need not satisfy the Ambrosetti–Rabinowitz condition. Using variational tools and the Nehari method, we show that the Dirichlet problem has at least three ...

The Nodal Closet

International Journal of Art, Culture, Design, and Technology, 2011
The synthesis of this text comes from a contemporary appraisal of the term “the closet” and its current place in culture since the advent of cybernetics. The authors’ assertion is that this metaphor, one that is rooted in the iconography of the late-capitalist home, is in a moment of transition and constant redefinition.

Observation of Nodal Cilia Movement and Measurement of Nodal Flow

2009
Mammalian left-right determination is a good example of how multiple cell biological processes coordinate in the formation of a basic body plan, but until recently its mechanism was totally elusive. In the past 10 years, molecular genetic studies of kinesin and dynein motor proteins, live-cell imaging techniques, and theoretical studies of fluid ...

Visualization of Mouse Nodal Cilia and Nodal Flow

2013
The earliest left-right asymmetry in mouse development arises in 7.5 days, at the ventral surface of the embryonic node. The node cells possess monocilia beating in rotatory fashion to generate fluid flow from the right to the left (nodal flow). The direction of nodal flow will determine the side of expression of nodal, the responsible gene for ...

Pelvic Nodal Imaging

Radiologic Clinics of North America, 2012
Detection of nodal metastases in men with pelvic urogenital malignancies is important for accurate staging and has therapeutic and prognostic implications. Knowledge of clinical anatomy of these nodes and the lymphatic pathways is critical for assigning the correct N or M staging and to assess the treatment response.

Peritumoral and Nodal Muciphages

The American Journal of Surgical Pathology, 1998
Three patients who underwent surgery for cancer showed Alcian blue positive cells in the sinusoids of the regional lymph nodes and, in one case, extensive infiltration in the soft tissues around the tumor. The cells contained variably sized vacuoles that occasionally indented the nuclei, imparting a signet-ringlike appearance.

A stabilized conforming nodal integration for Galerkin mesh-free methods

, 2001
Domain integration by Gauss quadrature in the Galerkin mesh-free methods adds considerable complexity to solution procedures. Direct nodal integration, on the other hand, leads to a numerical instability due to under integration and vanishing derivatives
