Ready ... Go: Amplitude of the fMRI Signal Encodes Expectation of Cue Arrival Time [PDF]

, 2009
What happens when the brain awaits a signal of uncertain arrival time, as when a sprinter waits for the starting pistol? And what happens just after the starting pistol fires? Using functional magnetic resonance imaging (fMRI), we have discovered a novel

Green molecularly imprinted polymers for sustainable sample preparation

Journal of Separation Science, 2021
AbstractThe use of molecularly imprinted polymers in sample preparation as selective sorbent materials has received great attention during the last years leading to analytical methods with unprecedented selectivity. However, with the progressive implementation of Green Analytical Chemistry principles, it is necessary to critically review the greenness ...

Sustainability in motion: Investigation of automated gravimetric sample preparation in industrial liquid chromatography

Green Analytical Chemistry
For analysis with liquid chromatography (LC), samples and calibration standards generally require a dilution by a factor of 103 to 106. To guarantee a high accuracy, sample preparation usually employs high-volume pipettes and volumetric flasks for ...

How to evaluate methods used in chemical laboratories in terms of the total chemical risk? – a ChlorTox Scale

Green Analytical Chemistry, 2023
Reliable assessment of the health and environmental risk associated with the use of chemicals is critical to objectively evaluate the greenness and whiteness of an analytical method. An objective and useful way of risk assessment should take into account

Time variation of Kepler transits induced by stellar spots - a way to distinguish between prograde and retrograde motion. II. Application to KOIs [PDF]

, 2015
Mazeh, Holczer, and Shporer (2015) have presented an approach that can, in principle, use the derived transit timing variation (TTV) of some transiting planets observed by the $Kepler$ mission to distinguish between prograde and retrograde motion of ...
