Bounce from inflation

How to bounce back from adversity.

Shape from Second-Bounce of Light Transport

This paper describes a method to recover scene geometry from the second-bounce of light transport. We show that form factors (up to a scaling ambiguity) can be derived from the second-bounce component of light transport in a Lambertian case. The form factors carry information of the geometric relationship between every pair of scene points, i.e., distance between scene points and relative surfa...

An Open Universe from Valley Bounce

It appears difficult to construct a simple model for an open universe based on the one bubble inflationary scenario. The reason is that one needs a large mass to avoid the tunneling via the Hawking Moss solution and a small mass for successful slowrolling. However, Rubakov and Sibiryakov suggest that the Hawking Moss solution is not a solution for the false vacuum decay process because it does ...

Drops can bounce from perfectly hydrophilic surfaces

Drops are well known to rebound from superhydrophobic surfaces and from liquid surfaces. Here, we show that drops can also rebound from a superhydrophilic solid surface such as an atomically smooth mica sheet. However, the coefficient of restitution CR associated with this process is significantly lower than that associated with rebound from superhydrophobic surfaces. A direct imaging method al...

"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...
