Neutrino oscillations beyond the Standard Model
We address the possible impact of New Physics on neutrino oscillation
experiments. This can modify the neutrino production, propagation and/or
detection, making the full cross section non-factorizable in general. Thus, for
example, the neutrino flux may not be properly described assuming an unitary
MNS matrix and/or neutrinos may propagate differently depending of their Dirac
or Majorana character. Interestingly enough, present limits on New Physics
still allow for observable effects at future neutrino experiments.Comment: 2 pages, 2 figures, Presented at the Neutrino 08 Conference,

Impact of right-handed interactions on the propagation of Dirac and Majorana neutrinos in matter
Dirac and Majorana neutrinos can be distinguished in relativistic neutrino
oscillations if new right-handed interactions exist, due to their different
propagation in matter. We review how these new interactions affect neutrino
oscillation experiments and discuss the size of this eventually observable
effect for different oscillation channels, baselines and neutrino energies.Comment: 26 pages, 5 figure

Matter effects and CP violating neutrino oscillations with non-decoupling heavy neutrinos
The evolution equation for active and sterile neutrinos propagating in
general anisotropic or polarized background environment is found and solved for
a special case when heavy neutrinos do not decouple, resulting in non-unitary
mixing among light neutrino states. Then new CP violating neutrino oscillation
effects appear. In contrast to the standard unitary neutrino oscillations these
effects can be visible even for two flavour neutrino transitions and even if
one of the elements of the neutrino mixing matrix is equal to zero. They do not
necessarily vanish with and they are different for various
pairs of flavour neutrino transitions (), (), (). Neutrino oscillations in vacuum and Earth's
matter are calculated for some fixed baseline experiments and a comparison
between unitary and non-unitary oscillations are presented. It is shown, taking
into account the present experimental constraints, that heavy neutrino states
can affect CP and T asymmetries. This is especially true in the case of
oscillations.Comment: 18 pages, 6 fig

Clinical, echocardiographic, and pacing parameters affecting atrial fibrillation burden in patients with tachycardia-bradycardia syndrome
Background: The influence of various factors on atrial fibrillation (AF) development in the population of tachycardia-bradycardia syndrome (TBS) patients remains unclear. There are no data on the impact of different right ventricular pacing percentage (RVp%) profiles.
Aim: The purpose of the study was to evaluate the relationship between the AF burden (AFB) and various clinical, echocardiographic, and pacing parameters in TBS patients.
Methods: We performed a prospective, one-year registry of TBS patients with documented AF referred for dual-chamber pacemaker (DDD) implantation.
Results: The data of 65 patients were analysed. The median 12-month RVp% and AFB was 9.4% and 1.0%, respectively. During the follow-up 14% of patients had no AF (p = 0.003), and the withdrawal of AF symptoms was observed in 49% of patients (p < 0.0001). The AFB was related to the left atrium diameter (r = 0.31, p = 0.02), especially in the subjects with left ventricular ejection fraction < 60% (r = 0.44, p = 0.04). Based on the relative change of RVp%, three groups of various RVp% profile were established: stable, decreasing, and increasing RVp%. In the stable RVp% group (n = 21) there was a quadratic correlation between the 12-month RVp% and AFB (r = 0.71, p = 0.0003). In the stable RVp% > 20% subgroup there was a significant increase of AFB in comparison to the RVp% ≤ 20% subgroup (ΔAFB 1.8% vs. 0.0%, p = 0.03, respectively). In the increasing RVp% group (n = 28) the AFB increased whereas in the decreasing RVp% (n = 16) it remained stable (ΔAFB 0.67% vs. 0.0%, p = 0.034, respectively).
Conclusions: DDD implantation in TBS patients is related to a significant reduction in AF symptoms, and left atrial diameter correlates with cumulative AFB in the mid-term observation. Stable RVp% > 20% is associated with AF progression whereas lower stable RVp% may stabilise AF development. Increasing RVp% may be associated with the AFB increase in comparison to the decreasing RVp% subgroup in which AFB remains stable.Background: The influence of various factors on atrial fibrillation (AF) development in the population of tachycardia-bradycardia syndrome (TBS) patients remains unclear.
