Memory Augmentation Unlocks Efficient Chain-of-Thought Reasoning

Simeng Zhang, Yilong Chen, Wenyuan Zhang +4

Large language models often rely on Chain-of-Thought (CoT) reasoning to solve complex tasks, but verbose reasoning traces introduce substantial inference overhead. CoT compression…

LCST and Closed-Loop Phase Behavior in Non-Associating Fully Symmetric Multicomponent Polymer Systems

Artem Petrov, Alfredo Alexander-Katz

Multicomponent liquids can phase separate upon heating, exhibiting a lower critical solution temperature (LCST). Moreover, a narrow class of materials can undergo disordering trans…

Prime Fano threefolds in positive characteristic

Akihiro Kanemitsu, Hiromu Tanaka

We prove that every prime Fano threefold of genus $\geq 7$ in positive characteristic is a linear section of a Mukai variety.

The Exceedance Design Effect: Effective Sample Size for Thresholds under Clustering

Adam Noonan

Many machine-learning systems set a threshold at a quantile of a calibration set: conformal predictors that promise 90% coverage by drawing their cutoff at the calibration set's 90…

Meandering stripes in the frustrated $J_{1}$ - $J_{2}$ Ising model on the honeycomb lattice

Denis Gessert, Martin Weigel, Wolfhard Janke

We study the frustrated $J_{1}$ - $J_{2}$ Ising model on the honeycomb lattice with ferromagnetic nearest-neighbor couplings fixed at $J_{1} = 1$ and strong antiferromagnetic next-nearest-ne…

Mukai bundles and Brill-Noether generality for prime Fano threefolds in positive characteristic

Hiromu Tanaka

Let $X$ be a prime Fano threefold of genus $g \geq 8$ in positive characteristic. For every nontrivial decomposition $g = r s$ , we prove that there exists a unique Mukai bundle on $X$ …
