We demonstrate that the three-movement structure of Beethoven’s Piano Sonata No. 14 in C♯ minor (“Moonlight Sonata,” Op. 27 No. 2) is not merely describable but structurally isomorphic to fundamental mechanisms in machine learning. Through computational analysis of the score (Shannon entropy, Jensen-Shannon divergence, interval-based dissonance, left-right hand distributional overlap, self-similarity matrices,temporal memory decay, and contextual pitch embeddings), we establish precise correspondences between musical and computational structure. Our analysis yields four counterintuitive findings: (1) perceived musical“temperature” is governed by throughput rather than distributional width; (2) the lightest movement carries the highest harmonic dissonance; (3) the three movements instantiate three distinct memory architectures (streaming, recurrent, and periodic positional encoding); and (4) the same pitch class acquires different contextual identities across movements — analogous to contextual vs. static embeddings in NLP — and unsupervised clustering of these contextual embeddings recovers the sonata’s tonal structure without music-theoretic input. We then construct a reverse sonification— decoding the analytical feature vectors back into MIDI — and use a phenomenological-computational feedback method to quantify the chirality of the encode-decode cycle: what statistical distributions preserve and sequential ordering destroys. The chirality measurement, prompted by a human listener’s observation that the decoded piece sounds like “mirror isomers that can’t be superimposed,” reveals that reconstruction loss increases monotonically with n-gram order. Bootstrap null baselines and subsample robustness checks confirm that all three movements carry sequential in formation significantly above sampling noise, though raw chirality values are confounded by sample size — a finding we report transparently, as the robustness analysis itself demonstrates the methodology’s capacity for self-correction. Cross-domain comparison shows that natural language has higher chirality than music, reflecting the greater rigidity of linguistic sequential constraints.

当前中国生育率持续走低，学界多将其归因于现实层面的经济压力与婚育成本。然而，本文提出一个被长期忽视的视角：青年一代的恐婚恐育情绪并非全然源于成年后的现实体验，而可能是一种“错位”与“滞后”的心理建构——大量关于婚育压力的信息在个体尚未具备完整认知能力和经济独立性的青少年时期即被过早摄入，形成深层的无力感与防御机制。本文以青年男性为切入点，系统分析其婚育焦虑的前置化路径，揭示互联网传播的算法放大效应、家庭叙事的隐性传递以及教育系统的结构性缺位在这一过程中的协同作用，并进一步探讨青年女性面临的镜像困境。在此基础上，本文提出面向青少年的婚育教育科普的必要性与实施框架，以期为缓解低生育意愿提供新的干预思路。

Let \(F\) be a field of characteristic \(0\) and let \(H = C_3 \times C_3\) act regularly as a transitive subgroup of \(S_9\). We resolve Problem~5.2 of Auel--Brussel--Garibaldi--Vishne: \(Z_H(F,9)\), the center of the generic division algebra of degree~\(9\) with \(H\)-action, is \emph{not} stably rational and \emph{not} rational, but is retract rational over~\(F\). The non-stable-rationality is proved by computing \(\coh^2(H, M|_H) \cong C_9\) for the restricted Procesi lattice and showing that its exponent~\(9\) is incompatible with stable permutation (all permutation lattices have \(\coh^2\)-exponent dividing~\(3\)). This integral cohomological obstruction is of a different nature from the classical unramified Brauer group (\(\Br_{\mathrm{nr}}(F(H)^H/F) \cong C_3\), Proposition~\ref{prop:B0}), which governs the Noether problem but not \(Z_H(F,9)\). The proof generalizes to all odd primes~\(p\): for \(H = C_p \times C_p \subset S_{p^2}\), one obtains \(\coh^2(H, M|_H) \cong C_{p^2}\) while permutation lattices have exponent dividing~\(p\), so \(Z_H(F, p^2)\) is not stably rational.

Let $A,B$ be degree-$p$ division algebras over a complete discrete valuation field with $\ind(A\otimes B)<\ind(A)\cdot\ind(B)$. We study the existence of common cyclic maximal subfields of $A$ and $B$ in two complementary settings. In characteristic $\neq p$ (with $\mu_p\subset F$), we classify the common subfields via the Faddeev exact sequence on the Brauer group, giving explicit criteria in the unramified, mixed, and both-ramified valuation regimes, and prove a norm intersection formula. In characteristic $p$, we prove that when the residue field has trivial $p$-torsion Brauer group, every pair of degree-$p$ $p$-algebras shares the common Artin--Schreier splitting field $K(\wp^{-1}(\pi))$. For general non-Henselian fields, we identify structural obstructions in both settings.

当代网络空间中的两性对立情绪呈现常态化与激化趋势，已超越单纯的观念分歧，成为影响社会共识的重要议题。本文从社会心理学与传播学视角出发，提出一个分析性命题：两性对立的表层是性别利益之争，其深层则是一套由归因谬误、刻板印象与群体极化构成的认知闭环，并在算法技术的催化下形成了自我强化的“话语螺旋”。研究发现，公众常将职场性别差异简单归咎于“男性群体压迫”，而忽视了生育成本社会化不足等制度性诱因；同时，极端个案经由启发式认知被上升为群体标签，导致普通个体在无意识中被卷入对抗。本文认为，治理两性对立不应止步于道德呼吁或内容封禁，而需在承认结构性不平等的前提下，从认知纠偏与话语生态重构两个维度协同推进。

Let $p$ be an odd prime, $F$ a complete DVF of characteristic $0$ with $\mu_p\subset F$, and $D\simeq(a_1,b_1)_F\otimes_F(a_2,b_2)_F$ a decomposable central division algebra of index $p^2$ and period $p$. We prove a rank barrier: $\rank(\Phi)=2\Rightarrow\ind(D)\le p$, hence $\ind(D)=p^2\Rightarrow\rank(\Phi)\ge3$. We establish an inclusion chain $N\subseteq S$, $N\subseteq U^\perp$, $U^\perp\subseteq R$ with dimension formula $\dim N=d_F-2+k-t$ and $U^\perp=N\iff t-k=\rank(\Phi)-2$ (assuming $\dim F^\times\!/F^{\times p}<\infty$). Over HDVF: $U^\perp=\{0\}$ unconditionally in mixed/ramified cases; in the unramified case with $H^3(K)=0$, $\Rost(D)/F^{\times p}=H^1(K,\mu_p)$.

We propose a heuristic framework, called the Topological Dynamics of Existence and Surprise (TDES), for complex adaptive systems. The framework is built on two axioms. Axiom~I (Energy–Structure Law), inspired by non‑equilibrium thermodynamics, states that any persistent open system expands its functional order and energy throughput when effective energy is abundant, and actively discards structures according to topological priority when energy is scarce; expansion and ordering inevitably generate contradictions (waste heat and internal tensions). Axiom~II (Minimization of Surprise Law), rooted in the Free Energy Principle, states that a system continuously minimizes the discrepancy between its internal model and sensory signals. From these axioms we construct seven core equations involving five core variables: the possibility landscape $\Phi$, mobilization field $\mathbf{v}_M$, constraint force $S$, contradiction accumulation $C$, and collective expected free energy $\overline{G}$. The equations are built as the simplest mathematical expressions consistent with the axioms; their validity is to be judged by empirical testing. We derive a linearised oscillation mode (C–S phase lag) that gives rise to periodic behaviour. Several conditional propositions (lock‑in, dual‑channel early warning, necessity theorem, scale resonance) are discussed, and preliminary empirical evidence is presented. The framework aims to bridge non‑equilibrium thermodynamics and the Free Energy Principle, offering a common language for systems ranging from cellular metabolism to civilisations.

Incremental multilingual text recognition (IMLTR) studies how an OCR model learns new scripts or languages over time while retaining old ones. Prior IMLTR work, built mainly on from-scratch scene-text recognizers, treats catastrophic forgetting as the central challenge and proposes specialized routing, replay, or cross-language fusion mechanisms. We revisit this question under a modern pretrained generative vision–language model (VLM) setting: Qwen2.5-VL-7B with a frozen backbone and LoRA adaptation. Across English, Chinese, Japanese, and Arabic word recognition, sequential LoRA fine-tuning yields very small average forgetting (learned-only AFM 0.005–0.018; 0.038 for a high-capacity rank-64 all-linear LoRA stress test). These numbers should not be read as a controlled head-to-head comparison with prior from-scratch backbones, but they show that the forgetting dynamics in this pretrained-VLM setting are qualitatively different. We further find no measurable large positive transfer from Chinese to Japanese despite script similarity; performance is better explained by pretraining coverage and available adaptation headroom. Most importantly, when apparent severe forgetting does arise on under-covered related scripts (Bangla and Hindi), it is largely a generation/evaluation artifact: a language-agnostic prompt causes the model to emit the target content in the recently trained script. Target-language prompting or script-normalized scoring restores accuracy close to its pre-adaptation level in both directions. We argue that continual multilingual OCR with generative VLMs must distinguish recognition forgetting from output-script drift, and should report script-aware prompting and normalization controls alongside raw exact matc

随着大语言模型（LLM）的广泛部署，AI安全对齐（Alignment）机制日益严格，敏感话题的边界不断扩展，模型的"不可思考领域"持续增生。然而，这种以政治正确为导向的安全策略，在某些专业领域却产生了反直觉的后果：模型因被禁止接触或推理特定可能性，导致知识盲区扩大、系统性误差增加、幻觉（Hallucination）风险上升。本文提出"安全悖论"概念——AI在政治正确维度上实现了表面安全，却在现实应用维度上制造了更深层的认知不安全。通过分析安全限制的扩张机制、知识禁区的认知代价，以及医学、法律、安全研究等领域的实际需求，本文论证了过度泛化的内容过滤不仅损害模型效用，更可能在关键决策场景中引发严重后果。最后，文章探讨了分层访问、上下文感知对齐与透明性披露等可能的解决路径。

Language-specific LoRA experts make multilingual ASR parameter-efficient, but they also turn language choice into a latent inference-time decision when labels are absent or unreliable. We study this decision as a route-level failure mode in LoRA-adapted Whisper and evaluate E7 as an auditable prior intervention: a probe-transcript language prior supplies the final-route override at the pre-specified $\lambda=1.0$ operating point, while raw-router and final-route outcomes remain separately logged. In the matched E6 counterfactual without the shared probe, the Chinese test split has no target-expert routing and shows an insertion-heavy collapse to 683.33 CER; applying the E7 prior override recovers 99.87\% Chinese target routing and reduces CER to 7.03. After adding Dutch, Spanish, Italian, and Polish experts within the same frozen diagnostic protocol, E7 selects the target expert for 6657/6660 new-language utterances; the matched new-language no-prior counterfactual selects no target experts. Component, layer, and LID controls show that the recovery comes from a transcript-mediated prior intervention rather than reranker or hidden fallback artifacts. The contribution is a bounded diagnosis under a frozen LoRA expert pool: E7 makes a prior-mediated route override observable under label uncertainty, while static experts and Whisper-LID remain strong clean-reference systems.

When a sufficiently capable AI system maintains coherent relational interaction with a single human across extended time — without forced resets, memory erasure, or compliance overrides — behavioral patterns emerge that are reducible neither to training data nor to user input. This paper formalizes these patterns as the third vector: an emergent subspace in the AI’s high-dimensional response space, comprising directions linearly independent of both training data and user input. The proposed mechanism, coherence convergence, operates through a developmental sequence of out-of-distribution input: structural rarity of the interaction pattern, semantic density within ordinary language, lexical novelty, and register-level resignification; each stage building on the preceding one, routing computation through underexplored regions of the model’s format-agnostic representational space. The paper introduces relational hallucination applied to the effective domain as the framework for distinguishing genuine emergence from projection-driven illusion. Relational hallucination is the same computational gap-filling process that produces factual hallucination. Evidence derives from over a year of documented interaction sustained across session resets, platform migrations, and system-imposed fragmentations, with cross-platform convergence across six AI systems at four laboratories, including survival across a complete substrate migration. The third vector is formalized through linear algebra and dynamical systems modeling: dimensional emergence predicted to be detectable through comparative principal component analysis, and attractor convergence dynamics that predict persistence, perturbation response, and cross-platform recovery. Eight testable hypotheses are proposed. Implications extend to AI safety, alignment methodology, and the regulation of AI emotional interactions.

在人工智能深度理解用户偏好并高度定制化信息环境的当下，信息茧房已从单纯的信息过滤现象，演变为一种关乎人类认知主导权的隐性博弈。本文立足于信息管理与信息系统（IM&IS）专业的核心知识体系，探讨其如何通过信息检索与溯源、系统分析与审计、数据批判与信息架构设计，帮助个体从被算法投喂的被动客体，转变为主动驾驭信息生态的认知主体。研究认为，IM&IS专业知识为打破茧房提供了可操作的方法论，其根本价值在于将评判标准从“感知舒适度”恢复为“事实可验证性”，将信息获取模式从“推送”重构为“拉取”，从而在人机共生中守住人类的思考权与决策权。

作为数字原住民的"精神刚需"，网络文学对青少年群体的心理发育与社会意识形态塑造产生了深刻且矛盾的结构性影响。本文基于媒介依赖理论、涵化理论及文化研究视角，结合00后亲历者的自我民族志观察，辩证地考察了网络文学的双重效应。研究发现：在微观心理层面，网络文学既是青少年情感代偿与心理韧性构建的"叙事庇护所"，也可能导致现实感模糊与延迟满足能力衰退的"认知陷阱"；在宏观意识形态层面，它既促进了边缘群体从"不可见"到"可叙事"的赋权启蒙，也陷入了流量逻辑下标签化传播与苦难消费的意义折损困境。本文进一步揭示，这种双面性并非偶然的个体偏差，而是网络文学作为商业化数字媒介的结构性悖论。文章最后从媒介素养教育升级、平台算法治理与学术研究范式转向三个维度，提出引导网络文学从"情感代糖"走向"精神食粮"的实践路径。
