Issues related to compositional technique using the software environment Nodal are discussed. The particular focus in this paper is the use and characterisation of nodal networks. These networks are the generative engine of Nodal. Network configuration is explored by discussing the compositional process for the work “Network Study #1” that employs Nodal exclusively. Observations are made regard...

BACKGROUND The association between nodal ratio and survival has not been assessed in squamous cell carcinomas of the head and neck. METHODS This is a population-based analysis, using the Surveillance, Epidemiology, and End-Results database, to determine whether nodal ratio impacts survival in patients with oral cavity squamous cell carcinoma. RESULTS Between 1988 and 2005, 2955 new diagnose...

BACKGROUND Nodal, a TGF-β-related embryonic morphogen, is involved in multiple biologic processes. However, the expression of Nodal in hepatocellular carcinoma (HCC) and its correlation with tumor angiogenesis, epithelial-mesenchymal transition, and prognosis is unclear. METHODS We used real-time PCR and Western blotting to investigate Nodal expression in 6 HCC cell lines and 1 normal liver c...

Accumulation of Na(+) channels at the nodes of Ranvier is a prerequisite for saltatory conduction. In peripheral nerves, clustering of these channels along the axolemma is regulated by myelinating Schwann cells through a yet unknown mechanism. We report the identification of gliomedin, a glial ligand for neurofascin and NrCAM, two axonal immunoglobulin cell adhesion molecules that are associate...

In the maximum flow network interdiction problem, an attacker attempts to minimize the maximum flow by interdicting flow on the arcs of network. In this paper, our focus is on the nodal interdiction for network instead of the arc interdiction. Two path inequalities for the node-only interdiction problem are represented. It has been proved that the integrality gap of relaxation of the maximum fl...

Nodal signaling plays several vital roles in the embryogenesis process. However, its reexpression in breast cancer is correlated with cancer progression, metastasis and poor prognosis. Recently, Nodal has also been reported to regulate self-renewal capacity in pancreatic cancer. This study aimed to explore the role of Nodal in breast cancer stem cells (BCSCs) and the underlying mechanisms. Ther...

BACKGROUND AND PURPOSE In the present study, prognostic values of several CT-based pre-treatment nodal and treatment-related characteristics were evaluated among patients with squamous cell head and neck cancer treated with non-surgical modalities. PATIENTS AND METHODS Included were 79 patients with 210 pathological nodes, who underwent primary irradiation or chemoradiation. Several nodal cha...

BACKGROUND In patients with atrioventricular nodal re-entrant tachycardia, modifications of the antegrade atrioventricular nodal function curve caused by catheter ablation of the so-called slow pathway are heterogeneous, but have not yet been systematically evaluated. AIM To test the hypothesis that successful treatment is independent of specific electrophysiological modifications of atrioven...

This paper discusses performance implications of meshing degree (or nodal degree) for optical burst switching (OBS) mesh networks using one-way resource reservation protocols. The analysis is focused on the following topologies: rings, chordal rings with nodal degrees ranging from three to six, mesh-torus, NSFNET, ARPANET and the European Optical Network (EON). It is shown that the largest noda...

in this paper, the linearly conforming enriched radial basis point interpolation method is implemented for the elasto-plastic analysis of discontinuous medium. the linear conformability of the method is satisfied by the application of stabilized nodal integration and the enrichment of radial basis functions is achieved by the addition of linear polynomial terms. to implement the method for the ...
