We generalize the notion of regular polyhedral subdivision of a point (or vector) configuration in a new direction. This is done after studying some related objects, like the finest regular coarsening and the regularity tree of a subdivision. Properties of these two objects are derived, which confer more structure to the class of non-regular subdivisions, relating them to its (in a sense) close...

abstract: introduction: abiding with ethical discipline in nursing leads to improving nursing services and promoting the patient’s health. due to the fact that patients are the most critical elements in health care organizations, this study was carried out with the aim of determine compliance with professional ethics and its relationship with associated demographic factors from the vantage poin...

This paper shows that borrowers’ ethical behavior leads lending banks to loosen financing conditions when setting loan rates. We advance the banking literature by stressing that the previous financing loosening is enhanced when there is similarity of lenders and borrowers along their ethical domain given that such similarity brings about familiarity and trust in non-opportunistic behavior betwe...

Local review of research by ethics committees in the UK has long been held to be an important right of the local research ethics committee and, even with the introduction of the European Clinical Trials Directive, the governance arrangements for research ethics committees continue to allow for local review of multicentre studies. There is no requirement for local review in either the European U...

Segmentation of the left atrium is vital for pre-operative assessment of its anatomy in radio-frequency catheter ablation surgery, which is commonly used for treating atrial fibrillation. In this paper we present an automatic approach for segmenting the left atrium and its pulmonary veins from MR angiography (MRA) data sets. Based on the notion that in MRA the atrium becomes connected to surrou...

The entorhinal cortex (EC) is the primary site of interactions between the neocortex and hippocampus. Studies in rodents and nonhuman primates suggest that EC can be divided into subregions that connect differentially with perirhinal cortex (PRC) vs parahippocampal cortex (PHC) and with hippocampal subfields along the proximo-distal axis. Here, we used high-resolution functional magnetic resona...
