Response inhibition is an attention function which develops relatively early during childhood. Behavioral data suggest that by the age of 3, children master the basic task requirements for the assessment of response inhibition but performance improves substantially until the age of 7. The neuronal mechanisms underlying these developmental processes, however, are not well understood. In this stu...

We have obtained high-resolution cw coherent anti-Stokes Raman spectra of the nu(1) Q branch of methane in an underexpanded supersonic jet at temperatures as low as 31.5 K and pressures below 2 Torr.

This seemingly basic equation actually hides some sophisticated assumptions and concepts. First, it applies only to the time varying, alternating, or ac, components of the current and voltage. Secondly, it is not sufficient to just tell how big the voltage and current signals are, we must also say how they are related in time, since they are both timevarying, ac quantities. Finally, the sizeand...

BACKGROUND The seminal plasma is an excellent source for noninvasive detection of spermatogenesis. The seminal plasma of normospermic and azoospermic men has been analyzed for detection of spermatogenesis. METHODS Optical spectroscopy (Attenuated Total Reflectance-Infrared spectroscopy (ATR-IR) and Fourier Transform infrared spectroscopy (FT-IR) has been used to analyze the seminal plasma and...
