This paper presents a general 8th-order PDE method to generate Bézier surfaces from the boundary with position and tangent vector information. We extend the work on generating biharmonic Bézier surfaces by Monterde to generating Bézier surfaces based on a general 4th-order PDE. And further the results are extended to generate tetraharmonic Bézier surfaces by a general 8th-order PDE. The solutio...

Although several staging systems have been proposed for pancreatic neuroendocrine tumors (pNETs), the optimal staging system remains unclear. Here, we aimed to assess the application of the newly revised 8th edition American Joint Committee on Cancer (AJCC) staging system for exocrine pancreatic carcinoma (EPC) to pNETs, in comparison with that of other staging systems. We identified pNETs pati...

The approaches and interpretations of a class of 6th graders and a class of 8th graders in a U.S. middle school asked to engage in tasks that involved using observations to describe and classify samples is the subject of this paper. Overall 8th graders were better able to perform the tasks, suggesting a developmental advantage aspect. However, the descriptions of the rock and mineral samples re...

OBJECTIVE To evaluate the efficacy of intra-articular hyaluronic acid (IAHA) injection for hemiplegic shoulder pain (HSP) after stroke. METHODS Thirty-one patients with HSP and limited range of motion (ROM) without spasticity of upper extremity were recruited. All subjects were randomly allocated to group A (n=15) for three weekly IAHA injection or group B (n=16) for a single intra-articular ...

PURPOSE The aims of this study were to compare the 7th and 8th editions of the American Joint Committee on Cancer (AJCC) staging manuals on tumor, node, and metastasis (TNM) staging systems and to evaluate whether the 8th edition represents a better refinement of the 7th staging system, when applied for the classification of gastric cancers. MATERIALS AND METHODS A total of 5,507 gastric canc...
