维持一家公司的生存不能只靠神秘感,Spectral以高科技厂商自居,这才是它的真貌。1977年,他们推出第一部前级MS-One,后来衍生成DMC-10与DMC-20前级。这是当时第一部高速宽频的前级,频宽从DC-MHz,内部增益大到可以直接驱动低输出动圈唱头,而且也是首部真正双单声道结构,在RIAA等化线路中采用高精度电阻电容(比当时一...
Making use of exhaustive high-resolution MS/MS and multi-stage MSnspectra, combined with extensive metadata, the world’s largest (in terms of total spectra and data per compound) and most extensively curated mass spectral library delivers powerful unknown identif...
Library: A library is a database (AM or AMRT) that, in addition to the above, also contains reference mass spectral data, MS/MS, and/or MSndata on compounds. Multi-stage fragmentation in the mzCloud mass spectral library...
For comparison, we processed one ‘typical’ MassIVE dataset with 44 LC–MS/MS runs on a laptop computer; this took 150 min of wall clock time. Discussion Annotation scores of current in silico tools are not suited to separate correct from incorrect hits. Here we introduced the COSMIC ...

Compound identification in small-molecule research, such as untargeted metabolomics or exposome research, relies on matching tandem mass spectrometry (MS/MS) spectra against experimental or in silico mass spectral libraries. Most software programs use dot product similarity scores. Here we introduce the ...
Specify that the spectral spread is calculated for 50 ms frames with a 25 ms overlap. Get fs = fileReader.SampleRate; samplesPerFrame = round(fs*0.05); samplesOverlap = round(fs*0.025); samplesPerHop = samplesPerFrame - samplesOverlap; win = hamming(samplesPerFrame); while ~isDone(fileRe...
Library: A library is a database (AM or AMRT) that, in addition to the above, also contains reference mass spectral data, MS/MS, and/or MSn data on compounds. Multi-stage fragmentation in the mzCloud mass spectral library A schematic representation of a spectral tree within mzCloud. The...
(MS). Sensors using hundreds ofspectral bandsare referred to as hyperspectral. Civilianremote sensing satelliteshave operated in multi-spectral fashion since ETS-Landsat program in the 1970s. Now very high resolution (VHR) sensors such as Ikonos,Quickbird, Orbview etc., operate in space in MS ...
Calculate the skewness of the power spectrum over time. Calculate the skewness for 50 ms Hamming windows of data with 25 ms overlap. Use the range from 62.5 Hz tofs/2 for the skewness calculation. skewness = spectralSkewness(x,fs,...Window=hamming(round(0.05*fs)),...OverlapLength=round(...
