Unphysical artifacts are responsible for molecular orientation with half-cycle pulses
Unphysical artifacts molecular orientation half-cycle pulses Chemical Physics
2012/5/31
Sub-cycle electromagnetic pulses in the Terahertz region are considered to be one of the best ways to orient molecules. The simplest option corresponds to half-cycles pulses in the sudden regime, for ...
Infrared behavior and gauge artifacts in de Sitter spacetime. I. The photon field
Infrared behavior gauge artifacts
2010/12/27
We study the infrared (long distance) behavior of the free photon field in de Sitter spacetime. Using a two-parameter family of gauge fixing terms, we show that the infrared (IR) behavior of the two-...

Improved measurement of carbonaceous aerosol: evaluation of the sampling artifacts and inter-comparison of the thermal-optical analysis methods
carbonaceous aerosol the sampling artifacts the thermal-optical analysis methods
2010/9/21
The sampling artifacts (both positive and negative) and the influence of thermal-optical methods (both charring correction method and the peak inert mode temperature) on the split of organic carbon (O...
Quantification of PM2.5 organic carbon sampling artifacts in US networks
PM2.5 organic carbon sampling artifacts US networks
2010/8/13
Field blanks (bQF) and backup filters (quartz-fiber behind quartz-fiber filter; QBQ) have been adopted by US long-term air quality monitoring networks to estimate PM2.5 organic carbon (OC) sampling ar...
Temporal variations of the fractal properties of seismicity in the western part of the north Anatolian fault zone:possible artifacts due to improvements in station coverage
Temporal variations fractal properties of seismicity north Anatolian fault zone
2009/11/16
Seismically-active fault zones are complex natural systems exhibiting scale-invariant or fractal correlation between earthquakes in space and time, and a power-law scaling of fault length or earthquak...
Dissolved organic matter in abyssal sediments: Core recovery artifacts
Dissolved organic matter abyssal sediments Core recovery artifacts
2014/4/22
We report measurements of pore-water dissolved organic carbon (DOC), dissolved organic nitrogen, total dissolved carbohydrates, dissolved free monosaccharides, and ammonium in recovered deep-sea sedim...
