(1) u2018The river flows in long sigmoid Curves,u2019 he wrote, u2018through an alluvial valley of no great width.u2019(2) The sigmoid may lie in the abdomen just inferior to the splenic flexure of the transverse colon, or in the right iliac fossa.(3) An enema shows a normal sized rectum and small caliber sigmoid and descending colon with a transition zone in colonic caliber occurring at the level of the splenic flexure.(4) First, the cumulative adoption of an innovation over time follows an S-shaped or sigmoid curve.(5) A series of unsuccessful attempts at scheduling surgery for her sigmoid colectomy followed because of complications with her neutrophil count and hospitalization for new onset atrial fibrillation.(6) Usually, a time course of plant growth follows a sigmoid curve, which can be described by a logistic function.(7) To isolate deviations from typical tree growth, we developed a model based on the amount of shoot elongation, which over equal time intervals approximates a sigmoid curve.(8) Although sigmoid volvulus can resolve spontaneously, nonoperative management begins with fluid resuscitation and antibiotics, followed by barium enema detorsion of the sigmoid .(9) The main body of the element comprises a longitudinal bony buttress that supports a very slight sigmoid row containing a minimum of five shallow tooth sockets.(10) The most frequently involved site is the sigmoid .(11) The growth curve of the fruit of Marisol clementine fitted a single sigmoid curve well.(12) Fruit development was described by an approximately sigmoid growth pattern based on fresh weight, irrespective of cultivar.(13) The majority of the curves display a simple sigmoidal pH dependence; however, several residues exhibit more complex shapes.(14) When onion seedlings recovered from water stress, the growth curve was sigmoidal and it took approximately 5-6 d before the elongation rate of the shoot or root reached a maximum.(15) A blood sample drawn at presentation was examined; unlike all other specimens studied, there was a sigmoidal increase at 550 nm, but not at 610 or 700 nm.(16) The stopping probability curves are distinctly sigmoidal in shape, and the decreasing slope at further distances reflects the attenuating effect of the distance u00d7 speed interaction.
