Design, Simulation, and Fabrication of a Hexagonal Microfluidic Platform for Culturing Neurons
Developing an organoid computing platform from neurons in vitro demands stable, precisely controlled microenvironments. To address this requirement, we designed, simulated, and fabricated a microfluidic device featuring hexagonal wells ($34.64\,\mathrm{μm}$ side length) in a honeycomb array connected by $20\,\mathrm{μm}$ channels. Computational fluid dynamics (CFD) modeling, validated by high mesh quality ($0.934$ orthogonal quality) and robust convergence, confirmed the architecture supports…

Multiscale analysis of large twist ferroelectricity and swirling dislocations in bilayer hexagonal boron nitride
With its atomically thin structure and intrinsic ferroelectric properties, heterodeformed bilayer hexagonal boron nitride (hBN) has gained prominence in next-generation non-volatile memory applications. However, studies to date have focused almost exclusively on small heterodeformations, leaving the question of whether ferroelectricity can persist under large heterodeformation entirely unexplored. In this work, we establish the crystallographic origin of ferroelectricity in bilayer hBN configur…

PSA: attrs 25.4 will change how it handles class-level kw_only to conform with dataclass transform rules (IOW act like type-checkers ex Mypy expect).
We found 0 cases in the wild where this would break anything so it’s on for NG APIs. Now is the time to stop us. 🤓

Make `kw_only=True` behavior consistent with dataclasses by huzecong · Pull Request #1457 · python-attrs/attrs
Summary This PR resolve #980. Before this change When kw_only=True is set on a class, all attributes are made keyword-only, including those from base classes. If an attribute sets kw_only=False, th...

CHAI: Command Hijacking against embodied AI
Embodied Artificial Intelligence (AI) promises to handle edge cases in robotic vehicle systems where data is scarce by using common-sense reasoning grounded in perception and action to generalize beyond training distributions and adapt to novel real-world situations. These capabilities, however, also create new security risks. In this paper, we introduce CHAI (Command Hijacking against embodied AI), a new class of prompt-based attacks that exploit the multimodal language interpretation abilitie…

1/N On nykyään on keksitty kaikenlaisia lukutaitoja. Tajusin, että vastuullisuuslukutaitoa ei löytynyt netin hakukoneella, joten sekin on syytä keksiä. Mitähän siihen liittyy? Luonnostellaanpa pikaisesti:
* KIELIOPPI: Tietoisuus vastuullisuudesta, millainen konsepti se on, mitä elementtejä siihen liittyy (konteksti, kenelle, miksi, asiat...)
* ITSE: Tietoisuus itsestä suhteessa maailmaan. Mikä on vastuullisuudessa ihmisen osa, vastuu suhteessa ihmisyyteen ja itseensä?

Obstruction-Driven Parity Inversion for Enhanced Optical Absorption in Hexagonal Transition Metal Dichalcogenides
The optical selection rule states that opposite parity between the valence and conduction bands is required for optical absorption to occur. However, monolayer hexagonal transition metal dichalcogenides (h-TMDs) such as $ \mathrm{MoS}_{2} $ exhibit pronounced optical absorption despite their nominally dipole-forbidden d-d transitions. In this Letter, we elucidate a parity inversion mechanism through which obstruction-driven band inversion promotes dipole-allowed optical transitions near the ban…

Constructions of Large m-Distance Sets on Triangular Lattice
An $m$-distance set is a collection of points such that the distances between any two points have $m$ possible values. We use two different methods to construct large $m$-distance sets on the triangular lattices. One is to use the first m smallest distances and find the largest cliques, and the other is using the notions of hexagons. Multiplicities of the distances were observed for comparison for the two methods.

Bei der kaputten Küchenmaschine das Zahnrad ausgetauscht, woraufhin die Masche nur lief, wenn der „Arm“ hochkant stand. Komisch. Alles auseinandergenommen, Anschlüsse dran, alle Teile rein.
In der Zwischenzeit hat der Saugroboter mit den Schrauben gespielt. Macht ja Nix. Teleskopmagneten benutzt um die Schrauben unter Sofa hervorzuholen. Nun löste sich der „Arm“. Wieder dran gemacht, Maschine läuft, festgeschraubt. Festgestellt, dass der Knauf abgebrochen ist. Bestellung aufgegeben.
