The 3D ultrasound (US) entrance inspires a multitude of automated prenatal
examinations. However, studies about the structuralized description of the
whole fetus in 3D US are still rare. In this paper, we propose to estimate the
3D pose of ...

We present a robust framework with computational algorithms to support
decision makers in sequential games. Our framework includes methods to solve
games with complete information, assess the robustness of such solutions and,
finally, appro...

The Alberti-Uhlmann criterion states that any given qubit dichotomy can be
transformed into any other given qubit dichotomy by a quantum channel if and
only if the testing region of the former dichotomy includes the testing region
of the la...

Inviscid bubble dynamics in a viscous fluid, moving with velocity V far
from the bubble, is considered. The Cauchy problem of recovering the bubble
evolution from its initial shape is completely solved without surface tension.
The well-po...

High Energy Astrophysical Phenomena
Core collapse within blue supergiant stars, as occurred within Sk
-69∘202/Supernova 1987A, is generally attributed to a merger of two
electron-degenerate cores within a common envelope, with a merged mass in
excess of 1.4 solar. Su...

The speed of an intensity pattern of polarization currents on a circle,
induced within a star by its rotating, magnetized core, will exceed the speed
of light for a sufficiently large star, and/or rapid rotation, and will, in
turn, generate...

We study estimation of large Dynamic Factor models implemented through the
Expectation Maximization (EM) algorithm, jointly with the Kalman smoother. We
prove that as both the cross-sectional dimension, n, and the sample size,
T, diverg...

Standard plane localization is crucial for ultrasound (US) diagnosis. In
prenatal US, dozens of standard planes are manually acquired with a 2D probe.
It is time-consuming and operator-dependent. In comparison, 3D US containing
multiple sta...
