Some metagenomic studies have suggested that less than 10% of the cells that comprise our bodies are Homo sapiens cells. The remaining 90% are bacterial cells. The description of this so-called human microbiome is of great interest and importance for several reasons. For one, it helps us redefine what a biological individual is. We suggest that a human individual is now best described as a supe...

The discovery of X rays by Roentgen in 1895 was one of the greatest discoveries with historical impact on on each and every one of us. The ability to view anatomy and infer function of inner organs and tissues of human body has provided immense potential that have led imaging to therapeutic arena through interventions and follow-up. How much imaging is appropriate is a legitimate question to as...

Many studies have documented high prevalence of burnout and compassion fatigue in oncology nurses. Burnout has detrimental effects on nurses, patients, and healthcare organizations. However, burnout interventions have been shown to improve the physical and mental health of nurses, patient satisfaction, and the organizational bottom line by reducing associated costs of burnout. Although treatmen...

We show that there is no (1 + ε)-approximation algorithm for the problem of covering points in the plane by minimum number of fat triangles of similar size (with the minimum angle of the triangles being close to 45 degrees). Here, the available triangles are prespecified in advance. Since a constant factor approximation algorithm is known for this problem [CV07], this settles the approximabilit...

Over the years, aligning IT and business strategies has remained an important, but sometimes elusive, challenge for executives. At the same time it has garnered quite an interest among the research community. This paper seeks to provide one explanation why alignment efforts struggle. The paper first addresses the distinction between strategies as plans and strategies as patterns in decisions an...

INTRODUCTION The aim of the study was to determine the most accurate threshold value for airway volume quantification based on specific experimental conditions. METHODS Ten scans from the airway prototype were obtained by using cone-beam computed tomography. The volume from each scan was measured with 8 values (25, 50, 70, 71, 72, 73, 74, and 75) of the threshold tool from the Dolphin softwar...

Colimits that satisfy the Van Kampen condition have interesting exactness properties. We show that the elementary presentation of the Van Kampen condition is actually a characterisation of a universal property in the associated bicategory of spans. The main theorem states that Van Kampen cocones are precisely those diagrams in a category that induce bicolimit diagrams in its associated bicatego...
