A liver mass post-Fontan operation [PDF]

QJM, 2014
### Learning Point for Clinicians This case report raises awareness of a rare devastating complication of congenital heart diseases that require correction via the “Fontan” operation. In these patients, liver cirrhosis and its complications are now being recognised including hepatocellular carcinoma.

Relativistic corrections to isotope shift in light ions [PDF]

, 2007
We calculate isotope mass shift for several light ions using Dirac wave functions and mass shift operator with relativistic corrections of the order of $(\alpha Z)^2$. Calculated relativistic corrections to the specific mass shift vary from a fraction of

Electron structure of topologically disordered metals

Condensed Matter Physics, 2005
Here two methods for calculating the density of states of electrons in conduction band of disordered metals are investigated. The first one is based on the usage of one-parameter trial electron wave function.

Constructing Point Form Mass Operators from Interaction Lagrangians [PDF]

, 2002
Starting from an interaction Lagrangian formed out of local fields, an interacting four-momentum operator is constructed by integrating the interaction Lagrangian over the forward hyperboloid.

Generalized method of Feynman-Pines diagram technique in the theory of energy spectrum of two-level quasiparticle renormalized due to multi-phonon processes at cryogenic temperature

Condensed Matter Physics, 2018
Theory of the spectrum of localized two-level quasi-particle renormalized due to interaction with polarization phonons at cryogenic temperature is developed using the generalized method of Feynman-Pines diagram technique.

A Lagrangian for mass dimension one fermionic dark matter

Physics Letters B, 2016
The mass dimension one fermionic field associated with Elko satisfies the Klein–Gordon but not the Dirac equation. However, its propagator is not a Green's function of the Klein–Gordon operator.

The unpolarized and polarized single-mass three-loop heavy flavor operator matrix elements A gg,Q and ∆A gg,Q

Journal of High Energy Physics, 2022
We calculate the gluonic massive operator matrix elements in the unpolarized and polarized cases, A gg,Q (x, μ 2) and ∆A gg,Q (x, μ 2), at three-loop order for a single mass.

Properties and temperature evolution of the spectrum of localized quasi-particles interacting with polarization phonons in two models

Condensed Matter Physics, 2016
Using the Feynman-Pines diagram technique, the energy spectrum of localized quasi-particles interacting with polarization phonons is calculated and analyzed in the wide range of energies at the finite temperature of the system. It is established that the

The three-loop polarized pure singlet operator matrix element with two different masses

Nuclear Physics B, 2020
We present the two-mass QCD contributions to the polarized pure singlet operator matrix element at three loop order in x-space. These terms are relevant for calculating the polarized structure function g1(x,Q2) at O(αs3) as well as for the matching ...

New Weinberg operator for neutrino mass and its seesaw origin

Journal of High Energy Physics, 2019
We consider a new Weinberg operator for neutrino mass of the form H u H ˜ d L i L j $$ {H}_u{\tilde{H}}_d{L}_i{L}_j $$ involving two different Higgs doublets H u , H d with opposite hypercharge, where H ˜ s d $$ \tilde{H}{s}_d $$ is the charge conjugated
