Stem cells are a critical component of most multicellular organisms as they are responsible for maintaining tissue turnover throughout the lifetime of the organism. This is such a fundamental mechanism of life that it is conserved from worms to humans. Loss of stem cells is associated with severe diseases and loss of stem cell function is at the heart of aging. Understanding the mechanisms resp...

Hemicorporectomy involves amputation of the pelvis and lower extremities by disarticulation through the lumbar spine with concomitant transection of the aorta, inferior vena cava, and spinal cord, as well as creation of conduits for diversion of the urinary and fecal streams. A review of the literature reveals that the surgical technique has been relatively unchanged since 1960. The standard an...
متن کاملOptimal back-to-front airplane boarding.
The problem of finding an optimal back-to-front airplane boarding policy is explored, using a mathematical model that is related to the 1+1 polynuclear growth model with concave boundary conditions and to causal sets in gravity. We study all airplane configurations and boarding group sizes. Optimal boarding policies for various airplane configurations are presented. Detailed calculations are pr...
