1+ hour, 3+ min ago   (496+ words) Offline reinforcement learning (offline RL) and large-language-model (LLM) alignment are typically studied as independent domains and each has developed its own pairwise comparison technique. Prior studies have validated pairwise classification exclusively within offline RL, leaving open the question of whether it…...

16+ hour, 12+ min ago   (495+ words) Steel storage tanks are erected on site by multi-cylinder hydraulic lifting, conventionally from one power unit feeding all cylinders through a flow divider. Decentralized alternatives have not been evaluated for this task, and modularity in fluid power is rarely quantified....

16+ hour, 22+ min ago   (361+ words) This research investigates the security of large language models (LLMs) with the aim of identifying key security and safety threats, control measures, and governance considerations that are relevant to their trustworthy adoption in the Extended Reality (XR) domain. To achieve…...

18+ hour, 47+ min ago   (507+ words) Modern corporate networks operate in increasingly complex and heterogeneous environments, which complicates the objective assessment of their current security state. This study proposes a dual-channel multi-level model for quantitative assessment of data security in corporate networks using a predefined list…...

19+ hour, 20+ min ago   (596+ words) Multi-station global navigation satellite system (GNSS) displacement-residual forecasting may benefit from neighbouring stations, yet unrestricted spatial aggregation can obscure station-local temporal dynamics and the independent value of spatial information. Whether neighbouring stations provide additional predictive information after a strong station-local…...

19+ hour, 32+ min ago   (296+ words) Museums face a conflict between energy-efficient gallery lighting and protecting light-sensitive collections from photochemical damage: increasing the luminous efficacy of white LEDs requires shifting spectral power toward the high-energy blue band, accelerating degradation of organic materials. Prior work treated these…...

19+ hour, 58+ min ago   (678+ words) Mapless deep reinforcement learning (DRL) navigation in dynamic indoor environments is difficult under single-frame 2D LiDAR, which reports where an obstacle is but not whether it is approaching. We introduce the Positional-Velocity Spatio-Temporal Attention Module (PV-STAM), a compact perception block (19,968 trainable…...

20+ hour, 20+ min ago   (538+ words) This study investigates how sentiment polarity relates to offensive function in Chinese online attacks, focusing on cases where offence is expressed implicitly rather than through explicit negative wording. Using a 1400-item Chinese online-text corpus derived from TOXICN and its pragmatics-oriented…...

20+ hour, 20+ min ago   (277+ words) Crop models are increasingly incorporated into web applications, but their user and programming interfaces are often developed separately from the model implementation. We extended Cropbox, a crop modeling framework written in Julia, to derive both interfaces from model declarations written…...

20+ hour, 47+ min ago   (259+ words) The dynamic response of soft terrain under repeated vehicle passes significantly influences off-road vehicle mobility and performance. The primary innovation of this research is the integration of loading–unloading hysteresis, multi-pass terrain-state evolution, and sensitivity analyses within a unified HSSTM-based…...
