针对工业互联网时间敏感业务在无源光网络（Passive Optical Network, PON）上行传输中对低时延、低抖动和差异化保障需求，本文提出一种基于流量类型优先级的整数线性规划带宽资源分配方法。首先，在设备侧工业网关引入流量整形机制，将原始工业业务抽象为具有周期、到达时间、传输窗口大小、时延容忍和抖动容忍等参数的工业汇聚流；随后，基于超周期窗口规划思想建立PON上行传输窗口调度模型，并设计ILP-OBJ1、ILP-OBJ2和ILP-OBJ3三种方案进行对比。仿真结果表明，ILP-OBJ2能够有效降低上行调度时延，其中等时流最大时延和平均时延相较ILP-OBJ1分别降低约78.6%和66.9%；ILP-OBJ3通过"先等时流、后循环流"的分阶段调度机制，在中高负载场景下具有更高的调度成功率。结果表明，所提方法能够提升工业互联网PON上行资源分配的确定性和业务适配性。

基于某地区2022-2025年普通国省道交通量数据、第一车道与第二车道路况评定数据及路线年报，采用描述性统计、Pearson相关分析、配对t检验和单因素方差分析（ANOVA），系统分析路况演变规律及交通荷载、路龄、车道位置的影响。结果表明：PQI年均值92.80，整体稳定；货车流量与PQI（r=-0.217）、RQI（r=-0.272）、RDI（r=-0.175）呈极显著负相关（p<0.001）；路龄超过15年后PQI、PCI、RQI显著下降（ANOVA，p<0.001）；第二车道（主要货运车道）PQI均值92.64，第一车道均值94.23，配对差值-1.59分（p<0.001）。货车荷载、路龄增长和车道位置是影响路况的关键因素。

Scholarly debates on China's agricultural growth between 1949 and 1986 continue to differ over the extent of the price scissors, the effect of heavy industrial investment, the role of the 1978 reforms, and the impact of decollectivization on irrigation. Using a single dataset and complementary econometric methods, this paper addresses each of these controversies. The results show that 1952--1957 was the only net extraction period across all three channels, after which the state channelled a net inflow of about 168.6 billion yuan into agriculture via fiscal and credit instruments. Heavy industrial investment exerted a significant positive lagged effect on agriculture, while the contemporaneous negative correlation stemmed from the zero-sum nature of the investment share indicator. The input-output elasticity shifted abruptly in 1970, and collective agricultural loans broke in 1971, both pointing to the rectification effects of the North China Agricultural Conference. Disaster prevention capacity fell from 0.70 under the collective era to 0.53 after household contracting, mainly because the collective maintenance system collapsed rather than because state investment declined. After 1979 the price elasticity of agricultural supply approached zero, suggesting that the 1979 procurement price increase acted more like a one-off recalibration than a sustained marginal incentive.

Vision-language-action (VLA) models show strong capabilities in single and dual-arm robotic manipulation. Prior works show coordinated bimanual behaviors can emerge from end-to-end learning, leveraging large vision-language backbones with continuous action prediction. However, as bimanual tasks become tightly coupled and execution constraints become critical, implicit coordination alone is insufficient to ensure reliable, interpretable, and stable behavior. In this work, we propose Co-VLA, a coordination-aware bimanual manipulation framework introducing explicit structural priors into VLA models. We instantiate our method on a state-of-the-art vision-language backbone by replacing its monolithic action head with a Structured Action Expert (SAE) designed for bimanual coordination. Specifically, we introduce explicit structure at the action generation level with a modular coordination-aware loss that shapes shared and residual latents according to task-specific structures. The shared latent encodes task-level coordination intent, while residual latents capture execution adjustments for each arm. At deployment, a Latent-Aware Controller (LAC) interprets the learned representations to modulate synchronization strength, execution asymmetry, smoothness, and safety constraints in real time. LAC operates at the joint-command level and remains compatible with standard control pipelines without requiring force or impedance control. Experiments across simulation and real-world benchmarks show Co-VLA significantly outperforms monolithic baselines, achieving a 27% success rate gain in tight-coordination tasks, more than doubling performance in OOD real-world scenarios (from 13% to 27%), and reducing task completion time by up to 25%.

We study high-frequency electromagnetic propagation in the rotating García--Díaz solution of Einstein gravity coupled to NLED. In this system, light is not governed only by the null cone of the spacetime metric, because the NLED field also behaves as an optical medium whose constitutive response determines the physical optical cones. Starting from the mixed electromagnetic potentials, we project the field $F$ and the excitation $P$ on a principal tetrad and obtain the aligned scalars $E$, $B$, $D$ and $H$. These scalars allow us to reconstruct the regular local constitutive branch connected with Maxwell theory through the map $(D,B)\mapsto(E,H)$. We then insert the resulting response matrix into the Fresnel characteristic problem. At the perturbative order considered here, the Fresnel quartic factorizes into two quadratic branches, each defining an effective optical metric. Both optical metrics admit Carter-type separation of the Hamilton--Jacobi equation and possess their own radial and angular potentials, critical constants and unstable critical families. By projecting these families onto the celestial sphere of a finite-distance observer, we obtain two critical contours, $Γ_+$ and $Γ_-$, which coincide in the Maxwell limit and split when the nonlinear constitutive response is active. We quantify this birefringent splitting through the maximum angular separation, the relative diameter shift and the normalized birefringent width. Numerical scans over the nonlinear coupling, spin and observer inclination show that the splitting is generated by the constitutive response, redistributed by rotation and stable under local projection changes within the perturbative domain. This provides a direct geometrical link between the local NLED response and a polarization-dependent critical structure on the observer screen.
