Axillary Nodal Evaluation in Breast Cancer: State of the Art.
Radiology, 2020Axillary lymph node (LN) metastasis is the most important predictor of overall recurrence and survival in patients with breast cancer, and accurate assessment of axillary LN involvement is an essential component in staging breast cancer.

Ideal nodal-net, nodal-chain, and nodal-cage phonons in some realistic materials
Physical Chemistry Chemical Physics, 2022We 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, 1988This 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, 2019We 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 ...

Physical Review B, 2011 We present a study of "nodal semimetal" phases, in which non-degenerate conduction and valence bands touch at points (the "Weyl semimetal") or lines (the "line node semimetal") in three-dimensional momentum space. We discuss a general approach to such states by perturbation of the critical point between a normal insulator (NI) and a topological ...

Observation of Nodal Cilia Movement and Measurement of Nodal Flow
2009Mammalian 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 ...

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.

Visualization of Mouse Nodal Cilia and Nodal Flow
2013The 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 ...
