Environmental studies and sciences (ESS), an inherently practical field, nonetheless demands greater attention to its theoretical assumptions as a necessary step toward continued intellectual and pedagogical development and real-world relevance. This need for theory arises from the status of ESS as an integrative interdiscipline—one practitioners of ESS celebrate, yet with considerably greater ...

With Enterprise Social Software (ESS) being increasingly used for internal communication and collaboration, an important question is how their success can be measured. In this paper we contribute to answering this question by investigating which methods and metrics organizations are currently applying for measuring ESS success. To do so, we have conducted 26 interviews with persons responsible ...

The concept of evolutionarily stable strategies (ESS) has been central to applications of game theory in evolutionary biology, and it has also had an influence on the modern development of game theory. A regular ESS is an important refinement the ESS concept. Although there is a substantial literature on computing evolutionarily stable strategies, the precise computational complexity of determi...

AIM We performed serial intracoronary studies of patients with stable coronary artery disease (CAD) to investigate the relationships among baseline endothelial shear stress (ESS), CAD progression, and vascular remodelling. Local haemodynamic factors are critical determinants of plaque progression, vascular remodelling, and clinical CAD manifestations. METHODS AND RESULTS The 3-D anatomy of co...

SUMMARY Rural western Canada relies heavily on family physicians with enhanced surgical skills (ESS) for surgical services. The recent decision by the College of Family Physicians of Canada (CFPC) to recognize ESS as a "community of practice" section offers a potential home akin to family practice anesthesia and emergency medicine. To our knowledge, however, a skill set for ESS in Canada has ne...

There are enormous amount of examples of Computation in nature, exemplified across multiple species in biology. One crucial aim for these computations across all life forms their ability to learn and thereby increase the chance of their survival. In the current paper a formal definition of autonomous learning is proposed. From that definition we establish a Turing Machine model for learning, wh...

Radiographic imaging of the nasal cavity and para nasal sinuses are essential for evaluation and planning. The routine imaging has been used for more than 5 decades, by the physicians, they correlate well only in acute sinusitis, indicated by air fluid level. Accurate assessment of the bony framework, soft tissue, anatomical variation, inflammatory and other pathological lesion of the paranasal...

Covalent modifications of histone proteins, in particular deacetylation of lysine residues, are important for the regulation of gene transcription both in normal and malignant cells. These processes are controlled by histone acetyltransferases and histone deacetylases (HDAC) and have up to now not been described in solid mesenchymal tumors. The present study shows differences in the HDAC1 and H...
