Super-harmonic injection locking of nano-contact spin-torque vortex oscillators
, 2016 Super-harmonic injection locking of single nano-contact (NC) spin-torque vortex oscillators (STVOs) subject to a small microwave current has been explored. Frequency locking was observed up to the fourth harmonic of the STVO fundamental frequency $f_{0}$

Vascular dementia: current concepts and nomenclature harmonization [PDF]
Dementia & Neuropsychologia, 2012 ABSTRACT Several types of cerebrovascular lesions are associated with cognitive decline, but the role of each type in dementia manifestation has yet to be determined. One of the greatest barriers of conducting clinicopathological studies in vascular dementia concerns the overlapping of nomenclature for these lesions.

Effect of Non-Linear Load Harmonics on Single phase Transformer Losses and Design Active Filter [PDF]
Engineering and Technology Journal, 2011 As a result of the negative effects unshaped on some of the components in power systems such as the transformers, a great concern was shown to treatment this phenomenon so we rise in this search by designing a suitable active filter with two strategies ...

The harmonic explorer and its convergence to SLE(4)
, 2006 The harmonic explorer is a random grid path. Very roughly, at each step the harmonic explorer takes a turn to the right with probability equal to the discrete harmonic measure of the left-hand side of the path from a point near the end of the current ...

Pediatric 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 ...
