Wave Packet Decoherence in Momentum Space

2004

We consider the development of decoherence between the momentum components of a wave packet of a non relativistic charged particle interacting linearly with the electromagnetic field in equilibrium at temperature T. By adopting from the beginning the electric dipole approximation the Hamiltonian assumes a form analogous to the one used in the context of quantum computing for an ensemble of two level systems. We obtain the characteristic vacuum and thermal decoherence times and we show that decoherence between different momenta is due to the onset of a correlation between each momentum component and the associated transverse photons that are also responsible of mass renormalization.

Pēcimplantācijas sindroms pacientiem ar abdominālās aortas aneirismu pēc endovaskulāras aneirismas ārstēšanas

2020

Ievads: Endovaskulāra aneirismas ārstēšana (EVAR - Endovascular Aneurysm Repair) ir rutīnā izmantota metode abdominālās aortas aneirismas (AAA) ārstēšanā. Pēcimplantācijas sindroms (PIS) ir labdabīga sistēmiska iekaisuma atbilde, ko novēro pēc EVAR un kas bioķīmiski un klīniski izpaužas ar iekaisumu bez infekcijas. Laboratoriskajiem rādītājiem ir loma PIS diagnostikā. Būtiski ir to diferencēt no infekcijas. Šobrīd asinsvadu ķirurgu vidū nav vienprātības par to, kā definēt PIS - febrils drudzis ir nemainīga paradigma, tomēr leikocitozes robežvērtības definīcijās atšķiras, tādējādi ietekmējot incidenci. Ir zināms, ka febriliem pacientiem ar leikocitozi agrīnā pēcoperācijas periodā izteikti do…
