Portable printer developed for fabrication of origami devices
In the present times, origami-inspired three-dimensional (3D) devices are being developed, where a single sheet of material is folded into small devices. These devices are being developed for medical applications like stents or surgical tools; agricultural devices like soil-sensors; and efficient spacecraft radiators or solar arrays that are used in space technology. Along with innovation, it is also important to focus on sustainable technology that can fulfill human needs and is adaptable to e…

Turbulence and dust fragility in protoplanetary discs
Dust growth from micron- to planet-size in protoplanetary discs involves multiple physical processes, including dust growth and fragmentation, the streaming instability, and pebble accretion. Disc turbulence and dust fragility matter at almost every stage. Previous studies typically vary one of them while fixing the other, failing to provide a complete picture. Here, we use analytical models and numerical dust evolution models DustPy to study the combinations of gas turbulence and dust fragilit…

DCA: Graph-Guided Deep Embedding Clustering for Brain Atlases
Brain atlases are essential for reducing the dimensionality of neuroimaging data and enabling interpretable analysis. However, most existing atlases are predefined, group-level templates with limited flexibility and resolution. We present Deep Cluster Atlas (DCA), a graph-guided deep embedding clustering framework for generating individualized, voxel-wise brain parcellations. DCA combines a pretrained autoencoder with spatially regularized deep clustering to produce functionally coherent and sp…

YouTube is like heroin because it pulls you in, hooks you, and slowly drains you. It is designed to be addictive and destructive, and that is exactly why it feels so hard to step away from it.
And yes, I know the excuse, maybe your favorite dealer has not set up shop on PeerTube. But that does not change the truth of the comparison.
PeerTube is like weed, it grows more naturally, it is gentler on you, and it still gives you a high without tearing apart your health and your lif…

1. Have a simple job to do. Figure out #Makefile will do the job.
2. Think a bit about portability. Makefile becomes slightly more complex.
3. You're finally done. It turns out that some stupid implicit rule in GNU Make fires and adds a `rm` at the end that removes part of the output.
4. Use #Meson.
Just an average #Gentoo day.
[UPDATE: Now I regret using Meson. If you do anything that's not 100% boilerplate, it just keeps throwing obstacles in your way.]

Unethical computer #protip: When you encounter a broken webpage, hit refresh a bunch of times. If there's an exception being generated and that metric is tied to an alert, you might trigger someone's pager.

HypER: Hyperbolic Echo State Networks for Capturing Stretch-and-Fold Dynamics in Chaotic Flows
Forecasting chaotic dynamics beyond a few Lyapunov times is difficult because infinitesimal errors grow exponentially. Existing Echo State Networks (ESNs) mitigate this growth but employ reservoirs whose Euclidean geometry is mismatched to the stretch-and-fold structure of chaos. We introduce the Hyperbolic Embedding Reservoir (HypER), an ESN whose neurons are sampled in the Poincare ball and whose connections decay exponentially with hyperbolic distance. This negative-curvature construction em…

Edge-On Disk Study (EODS) III: Molecular Stratification in the Flying Saucer Disk
Context: Investigating the vertical distribution of molecular content in protoplanetary disks remains difficult in most disks mildly inclined along the line of sight. In contrast, edge-on disks provide a direct (tomographic) view of the 2D molecular brightness. Aims: We study the radial and vertical molecular distribution as well as the gas temperature and density by observing the Keplerian edge-on disk surrounding the Flying Saucer, a Class II object located in Ophiuchus. Methods: We use new a…

Let's be honest. I've been a strong supporter of #OpenPGP (or #PGP in general) for a long time. And I still can't think of any real alternative that exists right now. And I kept believing it's not "that hard" — but it doesn't seem like it's getting any easier. The big problem with standards like that are tools.
#WebOfTrust is hard, and impractical for a lot of people. It doesn't really help how many tools implement trust. I mean, I sometimes receive encrypted mail via #EvolutionMail — and Evolution makes it really hard for me to reply encrypted without permanently trusting the sender!
The whole SKS keyserver mess doesn't help PGP at all. Nowadays finding someone's key is often hard. If you're lucky, WKD will work. If you're not, you're up for searching a bunch of keyservers, GitHub, or perhaps random websites. And it definitely doesn't help that some of these may hold expired keys, with people uploading their new key only to a subset of them or forgetting to do it.
On top of that, we have interoperability issues. Definitely doesn't speak well when GnuPG can't import keys from popular keyservers over lack of UIDs. And that's just the tip of the iceberg.
Now with diverging OpenPGP standards around the corner, we're a step ahead from true interoperability problems. Just imagine convincing someone to use OpenPGP, only to tell them afterwards that they've used non-portable tool / settings, and their key doesn't work for you.
That's really not how you advocate for #encryption.
