Physical Degradation Model-Guided Interferometric Hyperspectral Reconstruction with Unfolding Transformer
Interferometric Hyperspectral Imaging (IHI) is a critical technique for large-scale remote sensing tasks due to its advantages in flux and spectral resolution. However, IHI is susceptible to complex errors arising from imaging steps, and its quality is limited by existing signal processing-based reconstruction algorithms. Two key challenges hinder performance enhancement: 1) the lack of training datasets. 2) the difficulty in eliminating IHI-specific degradation components through learning-base…

It's the first and probably the last time an amazing punk band wrote a song on a hashtag that @… and me invented for a journalism project:

Today we're taking an (unplanned) break from streaming, but we'll be back next week with a new guest and a really fun topic!
Stay tuned

Efficient Band Structure Unfolding with Atomic-centered Orbitals: General Theory and Application
Band structure unfolding is a key technique for analyzing and simplifying the electronic band structure of large, internally distorted supercells that break the primitive cell's translational symmetry. In this work, we present an efficient band unfolding method for atomic orbital (AO) basis sets that explicitly accounts for both the non-orthogonality of atomic orbitals and their atom-centered nature. Unlike existing approaches that typically rely on a plane-wave representation of the (semi-)val…

Yes, I am a very political person. And that's why the unbelievable has happened in the last few days: as an old Linux and Unix user since the 1980s, I've switched from Fedora to Linux Mint... (and I'm still using FreeBSD too)
Technically a step backwards, as Fedora is far more up-to-date and modern, but politically and morally a step forward. Why?
Here in Europe, since the fascist, racist, narcissist, uneducated primitive moron and would-be dictator Trump became presi…

Your Token Becomes Worthless: Unveiling Rug Pull Schemes in Crypto Token via Code-and-Transaction Fusion Analysis
Rug pull scams have emerged as a persistent threat to cryptocurrency, causing significant financial losses. A typical scenario involves scammers deploying honeypot contracts to attract investments, restricting token sales, and draining the funds, which leaves investors with worthless tokens. Current methods either rely on predefined patterns to detect code risks or utilize statistical transaction data to train detection models. However, real-world Rug Pull schemes often involve a complex interp…

Envelopes of lines, unfoldings and breaking symmetry
We generalise the well-known ``embroidery'' envelopes of chords joining points at angles $t$ and $mt$ of a single circle in several ways. Firstly we allow $m$ to be rational (possibly negative) instead of integral, finding formulas for the number of cusps, points at infinity and self-intersections of these envelopes. Secondly we use two concentric circles instead of one, taking the chords to join a point of one circle to a point of the other. This construction allows the formation of different …

Medienkompetenz in der Schule beschränkte sich früher auf die Frage, ob die Lehrkraft in der Lage war, selbständig den Film in den Projektor einzulegen oder etwas später dann den Videorekorder unfallfrei einzuschalten.
Inhaltliche Medienkompetenz war bei drei empfangbaren öffentlich-rechtlichen Sendern und einem gerade aufkommenden RTL (das fast niemand hatte) noch nicht wirklich ein breites Thema. Zu Zeitungen haben wir was gemacht.
