Functional Source Separation-Identified Epileptic Network: Analysis Pipeline
This proof-of-concept (PoC) study presents a pipeline made by two blocks: 1. the identification of the network that generates interictal epileptic activity; and 2. the study of the time course of the electrical activity that it generates, called neurodynamics, and the study of its functional connectivity to the other parts of the brain.
Flexoelectric switching in cholesteric blue phases
We present computer simulations of the response of a flexoelectric blue phase network, either in bulk or under confinement, to an applied field. We find a transition in the bulk between the blue phase I disclination network and a parallel array of disclinations along the direction of the applied field. Upon switching off the field, the system is unable to reconstruct the original blue phase but gets stuck in a metastable phase. Blue phase II is comparatively much less affected by the field.
Static and dynamic Melvin universes
We briefly review the known properties of Melvin's magnetic universe and study the propagation of test charged matter waves in this static spacetime. Moreover, the possible correspondence between the wave perturbations on the background Melvin universe and the motion of charged test particles is discussed. Next, we explore a simple scenario for turning Melvin's static universe into one that undergoes gravitational collapse. In the resulting dynamic gravitational field, the formation of cosmic double-jet configurations is emphasized.
Momentum recoil in the relativistic two-body problem: Higher-order tails
In the description of the relativistic two-body interaction, together with the effects of energy and
angular momentum losses due to the emission of gravitational radiation, one has to take into account also
the loss of linear momentum, which is responsible for the recoil of the center-of-mass of the system. We
compute higher-order tail (i.e., tail-of-tail and tail-squared) contributions to the linear momentum flux
for a nonspinning binary system either along hyperboliclike or ellipticlike orbits.
The role of long distance contribution to the B->K(*)l+l- in the Standard Model
We investigate rare semileptonic B->K*l+l- by looking at the long distance contributions. Our analysis is limited to the very small values of physical accessible range of invariant mass of the leptonic couple q2. We show that the light quarks loop has to be accounted for, along with the charming penguin contribution, in order to accurately compute the q2-spectrum in the Standard Model. Such a long distance contribution may also play a role in the analysis of the lepton flavour universality violation in this process.
Cardiac function in adolescents and young adults with 22q11.2 deletion syndrome without congenital heart disease
Background
Diagnosis and treatment of 22q11.2 deletion syndrome (22q11.2DS) have led to improved life expectancy and achievement of adulthood. Limited data on long-term outcomes reported an increased risk of premature death for cardiovascular causes, even without congenital heart disease (CHD).
