Attractor dynamics underlie sequence working memory in data-constrained recurrent neural networks
吸引子动力学是数据约束循环神经网络中序列工作记忆的基础
Matthijs Pals, Jakob H. Macke
Sequences of stimuli can be maintained in working memory by encoding each item, together with its position, as a distinct pattern of neural population activity. Competing hypotheses about the underlying dynamics have bee…

Heteroskedasticity of neuronal population responses
神经元群体反应的异方差性
Michael Okun
Typical changes in a neuronal circuit's operating regime - such as shifts in sensorimotor conditions or in brain state - reshuffle firing rates across its neurons. One well-established key organising principle is rate pr…

Homeostatic Turnover, Repair, and the Demographic Form of Haldane's Principle
Ben Hardisty
Haldane's principle relates equilibrium mutation load to deleterious mutational input rather than to selection strength. We study this balance in a homeostatically regulated, damage-structured population where mutation o…

Performance Analysis for Leveraging AI to Reduce Energy Consumption of a Data Center: A Safe Deep Reinforcement Learning and Workload-Aware Framework
利用AI降低数据中心能耗的性能分析：一种安全深度强化学习与工作负载感知框架
Mohammad Ali
Abstract Electricity demand from data centers is rising quickly with the deployment of artificial intelligence (AI), and cooling remains the largest non-IT load, particularly in hot-arid climates. This paper presents a p…

From perovskite to infinite-layer nickelates: Hole concentration from x-ray absorption
从钙钛矿到无限层镍酸盐：基于X射线吸收的空穴浓度
R. Pons, M. Flavenot, K. Fürsich, E. Schierle 等
The difficulty of determining cation concentrations and oxygen stoichiometry in infinite-layer nickelate thin films has so far prevented clear experimental identification of the nickel electron configuration in the super…

Forecastability: a formal definition
可预测性：一个形式化定义
Peter Catt
This note states, in one citable place, the definition of forecastability developed from the author's work on the subject since 2009 and formalised in Catt (2026, arXiv:2603.27074). Forecastability is defined as the amou…
