Good morning!
Here are some photos from the #Mummelsee in the #Schwarzwald . We wanted to visit it last year already but somehow just managed to go there this time.
The lake itself is scenic and beautiful. But definitely a "hot spot". Luckily we were there at a day/time w…

For some reason the combination of 160K and my Mitutoyo 100x/0.90 objective means that as the last bits of ILD begin to etch away, substrate features become *less* visible.
I expected to see strong contrast at edges of substrate features when the ILD was etched away despite poly, STI trenches, and diffusion areas all being the same material (silicon).
But that's not what I'm seeing.
Going back to my archives, though, most of my good full die 100x shots are with the …

Radiocarbon analysis of turfgrasses can help cities measure greenhouse gas emissions
Cities around the world are working to limit emissions of climate-warming greenhouse gases, but there have been few ways of measuring whether those gases are actually decreasing in any given municipality. In new research, University of California, Irvine scientists have created an effective method to measure greenhouse gas emissions around cities—something that can help local governments gauge the effectiveness of their emission-curbing programs.

Projective Plane Subdivision Method For Initial Orbit Determination
Initial Orbit Determination (IOD) is the classical problem of estimating the orbit of a body in space without any presumed information about the orbit. The geometric formulation of the ''angles-only'' IOD in three-dimensional space: find a conic curve with a given focal point meeting the given lines of sight (LOS). We provide an algebraic reformulation of this problem and confirm that five is the minimal number of lines necessary to have a finite number of solutions in a non-special case, and t…

Small Value of cohomological dimension of group homomorphisms
We give the characterisation of cohomological dimension of group homomorphisms. In particular, we show the analogue of the Stallings-Swan theorem in the case of group epimorphisms.

What Gets Measured Gets Managed: Mitigating Supply Chain Attacks with a Link Integrity Management System
The web continues to grow, but dependency-monitoring tools and standards for resource integrity lag behind. Currently, there exists no robust method to verify the integrity of web resources, much less in a generalizable yet performant manner, and supply chains remain one of the most targeted parts of the attack surface of web applications. In this paper, we present the design of LiMS, a transparent system to bootstrap link integrity guarantees in web browsing sessions with minimal overhead. A…

I see a couple of other people using the #PuzzlePraise hashtag. ☺️
If you muted that hashtag permanently, you won’t see this toot, or any toot with that hashtag
EXCEPT:
1) if you are @ mentioned in a toot that contains a muted hashtag you’ll see it.
2) if a reply to one of your toots contains the muted hashtag you’ll see it.
I think its a great way to:
1) add cont…

Subjective Evaluation of Low Distortion Coded Light Fields with View Synthesis
Light field technology is a powerful imaging method that captures both the intensity and direction of light rays in a scene, enabling the reconstruction of 3D information and supporting a range of unique applications. However, light fields produce vast amounts of data, making efficient compression essential for their practical use. View synthesis plays a key role in light field technology by enabling the generation of new views, yet its interaction with compression has not been fully explored. …
