94.1% accuracy is definitely the exception to the rule for me, but the moves looked clear and obvious. I had wondered about whether patience against the pinned queen was accurate but reasoned it had to be.
Opponent allowing the pin on the queen was their undoing, obviously, but they still played with 82.5% accuracy. In most of my games, I'd be delighted to score that high.

In rebuke to Trump administration,
judge rules for Harvard on many key issues in the funding cutoff cases.
I’m glad the university held fast rather than buckling under to the bully.

A Survey on a Pair of Diophantine Equations
Given two relatively prime numbers $a$ and $b$, it is known that exactly one of the two Diophantine equations has a nonnegative integral solution $(x,y)$: $$ ax + by \ =\ \frac{(a-1)(b-1)}{2}\quad \mbox{ and }\quad 1 + ax + by \ =\ \frac{(a-1)(b-1)}{2}. $$ Furthermore, the solution is unique. This paper surveys recent results on finding the solution and determining which equation is used when $a$ and $b$ are taken from certain sequences. We contribute to the literature by finding $(x,y)$ when…

With Thomas Bonnefille's help, we successfully got USB to work on the SG200x! 🥳
The necessary patches are pending in LKML and we needed to add the 'b' in the compatible string (thanks Thomas for hinting us at the earlier patch). Don't ask, lol.
I have it all in a branch now including defconfigs and other hacks here:

Holistic Order Prediction in Natural Scenes
Even in controlled settings, understanding instance-wise geometries is a challenging task for a wide range of visual models. Although specialized systems exist, modern arts rely on expensive input formats (category labels, binary segmentation masks) and inference costs (a quadratic amount of forward passes). We mitigate these limitations by proposing InstaFormer, a network capable of holistic order prediction. That is, solely given an input RGB image, InstaFormer returns the full occlusion and …

Sequences of surfaces in $4$-manifolds
Let $(Σ_n)$ be a sequence of surfaces immersed in a $4$-manifold $M$ which converges to a branched surface $Σ_0$ .\\ We denote by $k^T_p$ (resp. $k^N_p$) the amount of curvature of the tangent bundles $TΣ_n$ (resp. normal bundles $NΣ_n$) which concentrates around a branch point $p$ of $Σ_0$ when $n$ goes to infinity. Alternatively $k^T\pm k^N$ measures how much the twistor degrees drop when we go from $Σ_n$ to $Σ_0$. For complex algebraic curves, $k^T+k^N=0$..\\ In some instances - 1) if…

Bounds on two-distance sets in Euclidean space and Unit Sphere
We establish upper bounds for the size of two-distance sets in Euclidean space and spherical two-distance sets. The main recipe for obtaining upper bounds is the spectral method. We construct Seidel matrices to encode the distance relations and apply eigenvalue analysis to obtain explicit bounds. For Euclidean space, we have the upper bounds for the cardinality $n$ of a two-distance set. \[ n \le \dfrac{(d+1)\left(\left(\frac{1+δ^2}{1-δ^2}\right)^2 - 1\right)}{\left(\frac{1+δ^2}{1-δ^2}\…

Diffusion^2: Turning 3D Environments into Radio Frequency Heatmaps
Modeling radio frequency (RF) signal propagation is essential for understanding the environment, as RF signals offer valuable insights beyond the capabilities of RGB cameras, which are limited by the visible-light spectrum, lens coverage, and occlusions. It is also useful for supporting wireless diagnosis, deployment, and optimization. However, accurately predicting RF signals in complex environments remains a challenge due to interactions with obstacles such as absorption and reflection. We in…
