Survival and Function of Bioengineered Cardiac Grafts

Circulation, 1999
Introduction —Patients with congenital heart disease frequently require graft material for repair of cardiac defects. However, currently available grafts lack growth potential and are noncontractile and thrombogenic. We have developed a viable cardiac graft that contracts spontaneously in tissue culture by seeding cells derived

ON SMOOTH ESTIMATION OF SURVIVAL AND DENSITY FUNCTIONS

Statistics & Risk Modeling, 1996
Incorporating the Hille theorem, smooth estimators of survival and density functions are considered, and their (asymptotic) properties are studied in an unified manner. A comparative picture of the so-called kernel and nearest neighbor methods and the proposed one is presented with due emphasis on the (asymptotic) bias and mean square error criteria ...

Survival Function

2016
Survival data arise when we are interested in the time of occurrence of an event, and the survival function describes the cumulative probability of surviving beyond a given time point in a given group of individuals. Methods to estimate the survival function can be classified in nonparametric and model-based methods and the main ones are described here.

Prolonged and functional survival with the asplenia syndrome

The American Journal of Medicine, 1986
Asplenia syndrome is a rare congenital complex of splenic agenesis, cardiac malformation, and malposition of the abdominal viscera. Prolonged functional survival is very uncommon, with death usually caused by severe infection or congestive heart failure.

Survival of function in the deafferentated vestibular nerve

Brain Research, 1983
After it has been deafferentated, spontaneous spike activity in the vestibular nerve is not abolished, but is drastically reduced 1-3 months post-op. If the nerve stump is cut again in the compensated animal, similarly directed postural asymmetries are re-induced, although of milder intensity. Electrical stimulation of the vestibular nerve stump evokes

FORM, FUNCTION, AND FITNESS: PATHWAYS TO SURVIVAL

Evolution, 2008
Two hypotheses have been considered in the literature regarding how anuran morphology reduces predation risk: by (1) improving escape swimming performance, or (2) using the tail as a lure to draw predator strikes away from the body of the tadpole. We investigated these hypotheses using a modification of the morphology, performance, and fitness path ...

Capacities, Survival Functions and Universal Integrals

2017
Based on the equality of survival functions related to n-ary vectors and capacities on \(X=\{1, \dots ,n \}\), the equality of universal integrals \({{\mathbf {I}}} (\mu ,{{\mathbf {x}}} )={{\mathbf {I}}} (\mu ,{{\mathbf {y}}} )\) is discussed and studied.

Nothing But Survival: On the Origin and Function of Literature

2016
For a long time literary theorists have been concerned with the question “What is literature?”. This issue does not raise the same interest in our days. After all, what really matters is what we do with literature, whatever it is. Time has come for a comparison between literary and evolutionary studies. The question we should ask is: “Why is literature?
