In addition to the steep voltage-dependent K 1 currents that play a role in repolarization of the heart, two major K conductances control the resting potential. The classical strong inward rectifier (IK1) is constitutively active and acts to stabilize the resting potential. During depolarization, the strong rectification of IK1 significantly reduces conductance, permitting a long action-potenti...

www.sciencemag.org SCIENCE VOL 323 13 FEBRUARY 2009 843 COVER An image of Mare Moscoviense on the lunar farside, taken by the Terrain Camera aboard the SELENE (Kaguya) spacecraft on 17 January 2008. Crater frequency distributions derived from such images yield ages of about 2.5 billion years for several volcanic deposits in this mare, indicating that volcanism on the lunar farside lasted about ...

The Lancet Series on Maternal and Child Undernutrition highlights the damaging eff ects of undernutrition during the fi rst 2 years of life on children's survival, health, attained schooling, and ultimately their human capital. The Series also points out that, although there are eff ective nutritional interventions, the international nutrition system, comprising international and donor organisa...

This paper smdies the average complexity of digital search trees from the successful search point of view. The average value of the successful search is used to evaluate the search time for a given record, the number of comparisons to insert a record, etc. The average value, however, is rather a poor measure and the need for higher moments of the successful search is obvious. For example, the v...

This paper presents Cmod, a novel tool that provides a sound module system for C. Cmod works by enforcing a set of four rules that are based on principles of modular reasoning and on current programming practice. Cmod’s rules flesh out the convention that .h header files are module interfaces and .c source files are module implementations. Although this convention is well-known, developing Cmod...
