Low-noise 1 THz niobium superconducting tunnel junction mixer with a normal metal tuning circuit [PDF]
, 1996 We describe a 1 THz quasioptical SIS mixer which uses a twin-slot antenna, an antireflection-coated silicon hyperhemispherical lens, Nb/Al-oxide/Nb tunnel junctions, and an aluminum normal-metal tuning circuit in a two-junction configuration.

A 100 GHz Josephson mixer using resistively-shunted Nb tunnel junctions [PDF]
, 1993 The authors describe preliminary mixer results using resistively shunted Nb/AlOx/Nb tunnel junctions in a 100-GHz waveguide mixer mount. The mixer utilizes robust, lithographically defined devices which have nonhysteretic I-V curves.

Mixer linearisation for software defined radio applications [PDF]
, 2002 The inherent non-linearity of mixers is particularly acute in broadband receiver design for software defined radio (SDR) applications. Here, the receiver frontend ‘sees’ not only the wanted channel, but also a number of nearby signals.

The effect of AM noise on correlation phase noise measurements [PDF]
, 2006 We analyze the phase-noise measurement methods in which correlation and averaging is used to reject the background noise of the instrument. All the known methods make use of a mixer, used either as a saturated phase detector or as a linear synchronous ...

Pediatric Blood &Cancer, EarlyView.ABSTRACT Blinatumomab has been shown to be highly effective for patients with pediatric B‐ALL and has recently become standard of care therapy. Due to its past use in the clinical trial setting, there is limited information available about real‐world administration.
