Optimal Dephasing for Ballistic Energy Transfer in Disordered Linear Chains

open access: yes, 2017
We study the interplay between dephasing, disorder, and openness on transport efficiency in a one-dimensional chain of finite length $N$, and in particular the beneficial or detrimental effect of dephasing on transport.

Nonanalytic corrections to the specific heat of a three-dimensional Fermi liquid [PDF]

open access: yes, 2005
We revisit the issue of the leading nonanalytic corrections to the temperature dependence of the specific heat coefficient, $\gamma (T)=C(T)/T,$ for a system of interacting fermions in three dimensions.

Enhancement of a High Speed De-Excitation System for Brushless Synchronous Machines by large blocking voltage semiconductors [PDF]

open access: yes, 2015
One of the main disadvantage of the synchronous machines with brushless excitation is that the field winding is not accessible for the de-excitation.

European Standard Clinical Practice Guideline and EXPeRT Recommendations for the Diagnosis and Management of Gastroenteropancreatic Neuroendocrine Neoplasms in Children and Adolescents

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Pediatric gastroenteropancreatic neuroendocrine neoplasms (GEP‐NENs) are extremely rare and clinically heterogeneous. Management has largely been extrapolated from adult practice. This European Standard Clinical Practice Guideline (ESCP), developed by the EXPeRT network in collaboration with adult NEN experts, provides (adult) evidence ...
