gyroscope, n.:
A wheel or disk mounted to spin rapidly about an axis and also
free to rotate about one or both of two axes perpindicular to
each other and the axis of spin so that a rotation of one of the
two mutually perpendicular axes results from application of
torque to the other when the wheel is spinning and so that the
entire apparatus offers considerable opposition depending on
the angular momentum to any torque that would change the directio…

Stray light in 3D porous nanostructures of single crystalline copper film
In the design of optical devices and components, geometric structures and optical properties of materials, such as absorption, refraction, reflection, diffraction, scattering, and trapping, have been utilized. Finding the ideal material with certain optical and geometric characteristics is essential for a customized application. Here, we fabricated unoxidizable achromatic copper films (ACFs) on Al2O3 substrates utilizing an atomic sputtering epitaxy apparatus. ACFs are made up of two regions ve…

I'm developing some thoughts on the steam machine: it's the best console and the best PC out on the market (soon), but it's not for me.
As a gaming apparatus it's the best because windows sucks, and the other consoles are so locked down that you are not allowed to move away any more once you buy a few games and then you get fucked over by a generational upgrade. In summary you are not in control.
Ad a deskop it's the best because the only two real alternatives, …

Stephen Miller has a theory about this political moment.
As President Trump expands his lawbreaking and dictatorial rule,
the powerful MAGA disinformation apparatus
—at Miller’s direction
—is supercharging public attention to the debate over Trump’s conduct in a way that’s designed to deeply polarize it.
That will force Americans to take a side in that standoff, Miller clearly believes,
driving them to embrace authoritarian rule,
though perhaps witho…

Inside Stephen Miller’s Secret Plan to Normalize Trump’s Dictator Rule
He wants to supercharge searing civil tensions to get low-information voters to embrace their inner authoritarian. Exactly two Democrats appear to fully grasp this.

I hold that genuine freedom can only be realized through the direct self-management of labor and the collective organization of social life by those engaged in it. No political vanguard, governmental apparatus, or capitalist hierarchy can provide emancipation, it must emerge from the autonomous initiative of workers acting in solidarity, constructing federations of production and community based on voluntary association and mutual responsibility.
For me, anarcho-syndicalism represents …

Digital ID – The New Chains of Capitalist Surveillance
[…] From passports to colonial passbooks, from welfare cards to border regimes, the apparatus of identification has always been tied to domination. Digital ID is simply the latest iteration of this long history, but with a scale and sophistication that makes its dangers even more profound. […]

Construction of Basis Functions for the Geometry Conforming Immersed Finite Element Method
The Frenet apparatus is a new framework for constructing high order geometry-conforming immersed finite element functions for interface problems. In this report, we present a procedure for constructing the local IFE bases in some detail as well as a new approach for constructing orthonormal bases using the singular value decomposition of the local generalized Vandermonde matrix. A sample implementation in MATLAB is provided to showcase the simplicity and extensionability of the framework.

Whisker-based Tactile Flight for Tiny Drones
Tiny flying robots hold great potential for search-and-rescue, safety inspections, and environmental monitoring, but their small size limits conventional sensing-especially with poor-lighting, smoke, dust or reflective obstacles. Inspired by nature, we propose a lightweight, 3.2-gram, whisker-based tactile sensing apparatus for tiny drones, enabling them to navigate and explore through gentle physical interaction. Just as rats and moles use whiskers to perceive surroundings, our system equips d…

Symmetric monoidal extensions and graph cobordisms between finite sets
Given a symmetric monoidal $(\infty,n)$-category $\mathcal{C}$ and a space $X$, we address the problem of explicitly describing the symmetric monoidal $(\infty,n)$-category freely obtained from $\mathcal{C}$ by adjoining $X$ new $n$-morphisms with prescribed sources and targets. We develop an apparatus of tools that allow one to detect in concrete situations such a free symmetric monoidal extension. As motivating application, we introduce a symmetric monoidal $(\infty,2)$-category ${\mathbb{G}\…

Increase in packing density during multi-layer powder spreading: An experimental and numerical study
A custom apparatus designed to isolate and replicate the spreading process of metal powder in additive manufacturing demonstrates a sudden and unexplained increase in packing density beyond layers 5 to 10. We replicate the experiments that lead to densification with the discrete element method (DEM) using \lethe{}, an open-source software framework. We show that large-scale multi-layer DEM simulations are able to reproduce the densification observed experimentally. Using the Lagrangian simulati…
