#scattering

#GutenMorgen, Ihr lieben PiepTrötys!

Was da draußen schon für 1 tolles Konzert ist

Gleich remote #BeamlineLeben: eine andere Gruppe kommt an unser 3D-Röntgenmikroskop: Ivan aus der #Coherent #XRay #Scattering and Imaging Group @DESY #Synchrotron . Es soll wohl seine letzte Messzeit werden – ein würdiger Abschied an der #GINIX.

Laut historischen Aufzeichnungen war er schon im Juni 2012 / run 11 an unserem Experiment, gleich starten wir für ihn den run 126.

Habt 1 strahlenden Tag!

Hey,
In one can use geo-nodes to scatter stuff.

The problem is to apply the modifier, i.e. on export, all those scattered instances turn into geometry - i.e. they are not shared/linked data.

On the side, I am hacking a plugin to try detect any clue that can help me spot when a scatter is coming in - i.e. I want to capture the transforms of each instance and the mesh data once. So I can make a multimesh.

any ideas?

After accounting for all variables, we're seeing something funny when subtracting backgrounds that put question marks on fundamental background subtraction practices in scattering.
So I wrote a little bit about it:

New view on #plant #phototropism: Air channels enhance light #scattering in Arabidopsis hypocotyls, thereby steepening the #light #gradient. This is required for an efficient phototropic response in Arabidopsis and Brassica.

`Using the increased rank of the #scattering #tensor along with its inverse operation, we demonstrate that the disordered #nonlinear medium can be used as a highly scalable nonlinear #optical operator for optical encryptions, all-optical multichannel logic AND gates, and optical kernel methods in machine learning.`

"Here, we realize a Fermi gas featuring both strong, tunable contact interactions and #photon-mediated, spatially structured long-range interactions in a transversely driven high-finesse #optical cavity. Above a critical long-range interaction strength, density #wave order is stabilized in the system, which we identify via its #superradiant light-#scattering properties."

Any pointers to good sources for non- spherical electron density distributions? Even a first order correction with S + P orbitals?

Not to be greedy, but any sources for MO for isolated amino acids or short peptides?

We had a terrific start yesterday for the #DPG spring meeting with Yimeng Wang's talk (on #EntanglementGeneration during #Scattering) and the two posters of Jonas Fischer and Josias Langbehn. #SAMOP23

"We used spectrophotometry, electron microscopy, and optical modelling to explain the mechanisms producing bright white tail feather tips of the Eurasian woodcock Scolopax rusticola. Their diffuse reflectance was approximately 30% higher than any previously measured feather. This intense reflectance is the result of incoherent light scattering from a disordered nanostructure composed of keratin and air within the barb rami"
