Superluminal variations in 3C 120, 3C 273, and 3C 345

open access: yesThe Astrophysical Journal, 1979
The superluminal behavior of 3C 120, 3C 273, and 3C 345 has been reexamined in light of new hybrid maps of these objects. The maps of 3C 273 and 3C 345 are consistent with superluminal expansion. 3C 120 appeared to expand superluminally from 1972.6 to 1974.5, but the evidence has been inconclusive since 1974.5.

Pseudo-Hall effect in single crystal 3C-SiC(111) four-terminal devices [PDF]

open access: yes, 2015
This article reports the first results on the strain-induced pseudo-Hall effect in single crystal 3C-SiC(111) four-terminal devices. The impact of crystal orientation and the direction of strain on this effect has been presented.

Spectrophotometry of 3C 232 and 3C 249.1 [PDF]

open access: yesSymposium - International Astronomical Union, 1986
We find indication of variability of the ratio Mg II 2934/2798 for 3C 232 and discuss the excitation mechanism of Mg II 2934. For 3C 249.1 we identified the following new lines: [Ne V] 3346, [Ne V) 3426 and He I 3884. Comments are made on continuum shapes; in both cases optical continuum variability is confirmed.

Direct Activation of STING in the Tumor Microenvironment Leads to Potent and Systemic Tumor Regression and Immunity

open access: yesCell Reports, 2015
Spontaneous tumor-initiated T cell priming is dependent on IFN-β production by tumor-resident dendritic cells. On the basis of recent observations indicating that IFN-β expression was dependent upon activation of the host STING pathway, we hypothesized ...

Fundamental piezo-Hall coefficients of single crystal p-type 3C-SiC for arbitrary crystallographic orientation [PDF]

open access: yes, 2016
Piezo-Hall effect in a single crystal p-type 3C-SiC, grown by LPCVD process, has been characterized for various crystallographic orientations. The quantified values of the piezo-Hall effect in heavily doped p-type 3C-SiC(100) and 3C-SiC(111) for ...

A Spectral Analysis of 3C 67 and 3C 190 [PDF]

open access: yesInternational Astronomical Union Colloquium, 1998
AbstractUsing new high resolution VLA and VLBA data and existing MERLIN data of 3C 67 and 3C 190, we find both sources have a complex spectral structure similar to larger Fanaroff-Riley type II sources. Our analysis of 3C 190 predicts either an unusually steep injection index of −0.8 and a young age, or a superposition of different age spectral ...
