Soil mercury spatial variations in the fault zone and corresponding influence factors [PDF]

Terrestrial, Atmospheric and Oceanic Sciences, 2017
Field measurements were performed using a LUMEX RA-915+ mercury vapour analyser to determine the gaseous mercury (Hg) concentrations in the soils of the North China plain, Loess Plateau, Changping District, Haiyuan fault zone, and north Beiluntai (BLT ...

Present-day movement characteristics of the Qinghai Nanshan fault and its surrounding area from GPS observation

Geodesy and Geodynamics
The Qinghai Nanshan fault is a larger fault in the Northeastern Xizang Plateau. In previous studies, its movement characteristics are mainly investigated with geological and seismic observations, and the tectonic transformation role of the fault on its ...

Long wavelength VCSEL-by-VCSEL optical injection-Locking [PDF]

, 2009
VCSEL-by-VCSEL optical injection-locking to obtain high cut-off frequencies of 1.3 μm Vertical-Cavity Surface-Emitting Lasers (VCSELs) is demonstrated. A detailed physical explanation of the underlying mechanism is presented.

A new method for the determination of the locking range of oscillators [PDF]

, 2007
A time-domain method for the determination of the injection-locking range of oscillators is presented. The method involves three time dimensions: the first and the second are warped time scales used for the free-running frequency and the external ...

Noise performance of frequency- and phase-locked CW magnetrons operated as current-controlled oscillators. [PDF]

, 2005
Low-power continuous wave ``cooker'' magnetrons driven from industrial-quality switch-mode power supplies have been frequency locked by driving them as current-controlled oscillators in a phase-lock loop (PLL).

Supplementary material from “Self-locking degree-4 vertex origami structures”

, 2016
A generic degree-4 vertex (4-vertex) origami possesses one continuous degree-of-freedom for rigid folding, and this folding process can be stopped when two of its facets bind together.
