Quasiclassical methods are used to define dynamical tunneling times in models of quantum cosmological bounces. These provide relevant new information compared with the traditional treatment by means probabilities. As shown here, dynamics bounce is not secure from reaching zero scale factor, re-opening question how classical singularity may be avoided. Moreover, examples studied remain small eve...

In this paper, working in a Friedman-Lemaitre-Robertson-Walker (FLRW) space-time, we recover, without invoking unconventional exotic matter, the generalized Friedman equation of quantum loop cosmology, and therefore cosmological bounce. We obtain result proposing new model framework modified teleparallel gravity, where Ricci scalar is replaced by torsion $T$. Furthermore show that associated pe...

Non-line-of-sight (NLOS) imaging methods reconstruct scenes hidden around one corner using indirect third-bounce illumination on a visible relay surface. We show how diffuse objects may exhibit specular behaviour in NLOS methods, and fourth- fifth-bounce can encode useful information, such as two corners.
