Tandem Mass Spectrum Identification via Cascaded Search
Accurate assignment of peptide sequences to observed fragmentation spectra is hindered by the large number of hypotheses that must be considered for each observed spectrum. A high score assigned to a particular peptide-spectrum match (PSM) may not end up being statistically significant after multiple testing correction. Researchers can mitigate this problem by controlling the hypothesis space i...
متن کاملBroadband nonlinear vibrational spectroscopy by shaping a coherent fiber supercontinuum.
Vibrational spectroscopy has been widely applied in different fields due to its label-free chemical-sensing capability. Coherent anti-Stokes Raman scattering (CARS) provides stronger signal and faster acquisition than spontaneous Raman scattering, making it especially suitable for molecular imaging. Coherently-controlled single-beam CARS simplifies the conventional multi-beam setup, but the vib...
متن کاملGain-switched CW fiber laser for improved supercontinuum generation in a PCF.
We demonstrate supercontinuum generation in a PCF pumped by a gain-switched high-power continuous wave (CW) fiber laser. The pulses generated by gain-switching have a peak power of more than 700 W, a duration around 200 ns, and a repetition rate of 200 kHz giving a high average power of almost 30 W. By coupling such a pulse train into a commercial nonlinear photonic crystal fiber, a supercontin...
متن کاملExtended Noise-shaping in Cascaded N-tone Σ∆ Converters
An N-tone Σ∆ converter is obtained by introducing N zeros in the noise transfer function (NTF) while maintaining a flat signal transfer function (STF). N-tone Σ∆ converters are particularly well suited for multi-carrier systems. While oversampling is a widely used technique to improve the resolution of the converter, different methods will have to be explored for systems with low over-sampling....
متن کاملPcf Deenability via Kripke Logical Relations (after O'hearn and Riecke)
The material presented here is an exposition of an application of logical relations to the problem of full abstraction for PCF. The point is to see Kripke logical relations as introduced by Jung and Tiuryn in [5] and used by O'Hearn and Riecke in [6] to give a logical characterization of sequentiality, within the mainstream of the classical notion of logical relations. The main di erence with r...
