Apparent survival of the salamander

open access: yes, 2007
Background Understanding the demographic processes underlying population dynamics is a central theme in ecology. Populations decline if losses from the population (i.e., mortality and emigration) exceed gains (i.e., recruitment and immigration). Amphibians are thought to exhibit little movement even though local populations often fluctuate dramatically

The escape problem under stochastic volatility: the Heston model

open access: yes, 2008
We solve the escape problem for the Heston random diffusion model. We obtain exact expressions for the survival probability (which ammounts to solving the complete escape problem) as well as for the mean exit time. We also average the volatility in order

Acoustic cavitation nuclei survive the apparent ultrasonic destruction of Albunex® microspheres

open access: yesUltrasound in Medicine & Biology, 1997
The hypothesis tested was that gas bodies capable of nucleating violent cavitation activity in vitro would survive the rapid disruption of Albunex microspheres by 1-MHz ultrasound. Human erythrocyte hemolysis was used as a proxy measure of cavitation.

Foray movements are common and vary with natal habitat for a highly mobile bird

open access: yesEcology and Evolution
Understanding dispersal is central to interpreting the effects of climate change, habitat loss and habitat fragmentation, and species invasions. Prior to dispersal, animals may gather information about the surrounding landscape via forays, or systematic,

Personalizing the Pediatric Hematology/Oncology Fellowship: Adapting Training for the Next Generation

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT The pediatric hematology‐oncology fellowship training curriculum has not substantially changed since its inception. The first year of training is clinically focused, and the second and third years are devoted to scholarship. However, this current structure leaves many fellows less competitive in the current job market, resulting in ...

One hundred ten consecutive primary orthotopic liver transplants under FK 506 in adults. [PDF]

open access: yes, 1991
An account is given of the 6- to 12-month survival, and causes of failure in 110 consecutive patients who underwent primary liver transplantation under treatment from the outset with FK 506 and steroids. The patient survival is 92.7%, and the first graft

Delayed mortality effects cut the malaria transmission potential of insecticide resistant mosquitoes [PDF]

open access: yes, 2016
Malaria transmission has been substantially reduced across Africa through the distribution of long-lasting insecticidal nets (LLINs). However, the emergence of insecticide resistance within mosquito vectors risks jeopardizing the future efficacy of this ...
