Gwen Snyder posted something on Saturday to the effect that “Fascists •need• the appearance of strength, and right now, Trump just looks weak.”
I think it’s easy for us evidence-hungry thinker types to underestimate just how much appearance matters. Massive rallies are not — •must• not be — the endpoint of resistance. However, neither are they purely symbolic. They have a real and concrete effect. They change perceptions, which change human behavior. Yes, they matter. They matter a lot.

“Are we the baddies?” is not a question anyone in the West has to ask themselves. There’s no question about it. You were. You are. Will you continue to be? That’s the only question that matters and the answer is entirely up to you.
Silence is complicity.
Inaction is complicity.
Apologism is complicity.
Do something!

Attached: 1 image More RAF jets are being sent to the Middle East, Keir Starmer has said after Iran threatened to target UK, French and US bases if the countries help stop strikes on Israel. Additional refuelling aircraft have been deployed from UK bases and more fast jets will be sent over, it is understood. The UK already has RAF jets in the Middle East as part of Operation Shader. https://www.thenational.scot/news/25239897.uk-jets-sent-middle-east-despite-calls-de-escalation/ 🕎 �…

Matrix models as tau functions of the UC hierarchy of integrable equations. II
We present a family of matrix models such that their partition functions are tau functions of the universal character (UC) hierarchy. This develops one of the topics of our previous paper arXiv:2410.14823. We found new matrix models associated with the product of two spheres with embedded graphs via a gluing matrix. We also generalize these studies to multi-matrix models case, which corresponds to the multi-component UC hierarchy.

A Tale of Two Systems: Characterizing Architectural Complexity on Machine Learning-Enabled Systems
How can the complexity of ML-enabled systems be managed effectively? The goal of this research is to investigate how complexity affects ML-Enabled Systems (MLES). To address this question, this research aims to introduce a metrics-based architectural model to characterize the complexity of MLES. The goal is to support architectural decisions, providing a guideline for the inception and growth of these systems. This paper brings, side-by-side, the architecture representation of two systems that …

Oriented hypergraphs and generalizing the Harary-Sachs theorem to integer matrices
Incidence-based generalizations of cycle covers, called contributors, extend the Harary-Sachs coefficient theorem for characteristic polynomials of the adjacency matrix of graphs. All minors of the Laplacian resulting from an integer matrix are characterized using their associated oriented hypergraph through a new minimal collection of contributors to produce the coefficients of the total-minor polynomial. We prove that the natural grouping of contributors via tail-equivalence is necessarily ca…

Witnessing PPT entanglement via rank analysis of (sub)matrices
We develop a new method for entanglement detection in bipartite quantum states, using the violation of the rank-1 generated property of matrices. The positive-semidefinite matrices form a convex cone that has extremal elements of only rank-1. But convex conic subsets resulting from presence of linear constraints allow extremal elements of rank > 1. The problem of deciding when a matrix is rank-1 generated, i.e a sum of rank-1 PSD matrices, has been studied extensively in optimization theory. Th…

The Integral Decimation Method for Quantum Dynamics and Statistical Mechanics
We present a method to numerically evaluate functional integrals called integral decimation (ID). It constructs a separable decomposition of the integrand as a spectral tensor train (STT), a continuous generalization of the matrix product state. ID builds the STT by mapping the integrand to an auxiliary many-body wavefunction that evolves in time from an initially unentangled state. Each body-ordered term of the action corresponds to a quantum gate, applied to the state during its evolution. Th…

Exploring Entanglement Entropy for a Particle on a Torus with constant Metric and constant $U(1)$-Gauge Field

Exploring Entanglement Entropy for a Particle on a Torus with constant Metric and constant $U(1)$-Gauge Field
In this paper, we focus on the entanglement entropy associated with a particle confined to a torus with constant metric and $θ$-terms related to a constant external $U(1)$-gauge field. Through this investigation, we aim to elucidate the interplay between geometric properties, topological terms, and entanglement entropy. Remarkably, we find that the presence of non-vanishing entanglement entropy is closely tied to fixing the metric. This insight highlights the significant influence of quantum e…
