Now is time for the spectrum of a Wolf-Rayet type of star: WR-7 also catalogued as V1687 Cyg.
It is a WC, meaning that it is a star rich in carbon. We can actually "see" the carbon and helium inner layers, because the intense stellar winds and a pronounced unstable hydrostatic equilibrium have expelled its outer hydrogen layers to interstellar space. The broad emission lines are trademark of these types of stars.

Added support for #MassSpec spectra comparisons using the spectral entropy similarity score to our #Spectra @bioconductor package (dev version):

Thanks Yuanyue Li for the #msentropy #rstats :rstats: package and support! 🥳

Schott derived were not consistent with the available observations of atomic #spectra. Schott was aware of the problem and indeed realised thay new physics was required. In retrospect, it's clear that Schott's attempt couldn't succeed without the new "mechanics" of quantum #physics.

The formulas for the radiation emitted by a charge in circular motion however, turned out to describe exactly the electromagnetic emission from charged particles in a circular accelerator which was discovered some 40 years later!

In the early 20th century, G. Schott set out to develop a model that would explain atomic #spectra and radioactivity, from classical #electrodynamics (from Maxwell's equations). As it turned out, he unwittingly discovered the mechanism of synchrotron radiation instead.

Join @particle today for Spectra starting at 9 AM PST.

Spectra is the #IoT conference for Particle's connected ecosystems. From enterprise customers, partners and advocates, to builders, developers and users, #Spectra is your opportunity to learn and discuss IoT market trends,… https://twitter.com/i/web/status/1671521680965943298

@translational_proteomics @lgatto no LIMS on my side - keep the mzML files organized by year/month of measurement and (importantly) xls sheets with info on samples, files, protocols for each project.

Recently I started storing the MS data of all our mzML (>20000) into a MariaDB database (using our MsBackendSql) to allow easy and fast MS data access from :rstats: usint our #Spectra package

Come on now, who had the idea of blasting out pinging noises all over the city to accompany the #spectra beam

Today I wrote a 5 minute piece with Facet in which 8 sine waves randomly drift through the audio spectrum, starting the next loop where they had previously ended.

The image with red lines on a gray background is the entire piece. The image with the yellow / multicolored lines on a black background is the first 30 seconds, captured by @GuyBirkin with foobar player

Facet code:
// 1. initialize "from" and "to" patterns at beginning - each command only runs once
$('from').noise(8).times(rf(1,FACET_SAMPLE_RATE/2)).set('from').once();
$('to').noise(8).times(rf(1,FACET_SAMPLE_RATE/2)).set('to').once();
// 2. every loop, start the sine wave frequencies at the previous "to" pattern values & ramp linearly to 8 new random locations in the spectrum, saving the pattern to disk and listening back
$('s').get('to').set('from').reduce(0).append(_.noise(8).times(rf(1,FACET_SAMPLE_RATE/2))).set('to').reduce(0).append(_.silence(n1)).iter(8,()=>{this.sup(_.sine(_.ramp(_.get('from').data[i],_.get('to').data[i],n1),n1),0,n1)}).saveas('spectralramps/'+Date.now()).full().audio().play();

// 3. after waiting however many iterations, stitch the resulting files together via:
$('s4').stitchdir('spectralramps',n1-(FACET_SAMPLE_RATE*0.05),'spectralramp');

Mid June is always a special time in Hobart with the Annual Dark Mofo Festival.

The Spectra installation by Ryoji Ikeda has been a regular landmark of the Festival and can been seen well over 100kms away on a clear night.

it always brings me a sense of joy to see it. A beacon of happiness for me.

Our #MsBackendSql :rstats: package is part of @bioconductor release 3.17 🎉

Allows our #Spectra package to store/read #MassSpec data to/from #SQL databases. #RforMassSpectrometry

Huh. Maybe #spectra (in the sense of algebraic topology) aren't that scary after all.

I just watched a duo of fantastic lectures by Mark Behrens, and he makes them feel both concrete and useful (where both of those words should be taken with the usual grain of salt whenever a mathematician says them, haha).

For the interested, here's a link to the first lecture:

My recent PR to the @bioconductor #xcms package has the ID 666 👹

well - no surprise, it comes with some devilishly good new functionality:
- fully based on the #Spectra and MsExperiment :rstats: packages
- code refactoring to increase performance
- ...
