PLANETARY SCIENCE: To Bounce or Not To Bounce

"Septal bounce".

APPEARANCE Appearance: The septal bounce is a paradoxical bouncing motion of the interventricular septum initially directed towards and then away from the left ventricle during early diastole (Fig. 1 and see Video, Supplemental Digital Content 1, which demonstrates characteristic septal bounce on cine SSFP 4-chamber images, http://links.lww.com/JTI/A16). It is accentuated by deep inspiration an...

Learning to Serve and Bounce a Ball

In this paper we investigate learning the tasks of ball serving and ball bouncing. These tasks display characteristics which are common in a variety of motor skills. To learn the required motor skills for these tasks the robot uses Relative Entropy Policy Search which is a state of the art method in Policy Search Reinforcement Learning. Our experiments show that REPS does not only converge cons...

How to bounce back from adversity.

Moon Bounce Eunt

The capability of enemy anti-aircraft and anti-ballistic-missile systems, naturally a matter of intense Interest to us, depends in part on the capability of a number of sub-systems. one of the most important of which is the radars used for target acquisition and tracking. We need to know the parameters of these radars as accurately as possible in order to plan penetration strategy and design th...

The brief resilience scale: assessing the ability to bounce back.

BACKGROUND While resilience has been defined as resistance to illness, adaptation, and thriving, the ability to bounce back or recover from stress is closest to its original meaning. Previous resilience measures assess resources that may promote resilience rather than recovery, resistance, adaptation, or thriving. PURPOSE To test a new brief resilience scale. METHOD The brief resilience sca...
