To solve the global path planning problem of ship in static and dynamic environment, we propose an improved ant colony algorithm to plan ship's navigation path. We use artificial potential field method compute force direction at initial iteration stage. The attraction function is modified improve efficiency hybrid algorithm. design pseudo-random state transition rule convergence by strengthening selection good paths. When updating pheromone, consider path's length, safety, smoothness a safer...
For information asymmetry in e-commerce platforms, question answering system (Q&A) and online comments are used to build trust relationship. Although reviews play a significant role reducing asymmetry, overload distortion also not negligible. In the study, text mining was extract various questions from Q&A obtain content that consumers most concerned about shopping, similarities differences of two results compared. The show has great influence on users' decision making. is only complementary...
Anatomical variation may represent a challenge in achieving close fit between prosthesis and patient's osseous geometry total knee arthroplasty (TKA). The purposes of this study were to determine whether the shape distal part femur differs among ethnicities, these differences affect femoral component standard prosthesis, additional availability with reduced mediolateral dimension for same anteroposterior improves across ethnicities.Femoral dimensions measured intraoperatively during 967 TKAs...
Effective user representations are pivotal in personalized advertising. However, stringent constraints on training throughput, serving latency, and memory, often limit the complexity input feature set of online ads ranking models. This challenge is magnified extensive systems like Meta's, which encompass hundreds models with diverse specifications, rendering tailoring representation learning for each model impractical. To address these challenges, we present Scaling User Modeling (SUM), a...
With the rapid development of social network, analysis for online users' emotions and tendencies has gradually developed.Sentiment relations on network made significant progress.Based data mining, this study summarized existing work about emotion analysis, three sentiment methods users.Furthermore, compared differences between Chinese English.
Superior laryngeal nerve block (SLNB) is a regional anesthesia technique for addressing airway response. However, SLNB on the efficacy of sedation in patients with delayed extubation unknown, particularly maxillofacial surgery (MS). The aim study was to assess whether ultrasound guided (UG) reduces incidence moderate severe cough MS free flap reconstruction.60 were randomly assigned GEA group (control group) and (UG-SLNB postoperatively, group). During initial two postoperative hours, cough,...

ABSTRACT: Achieving transition metal-catalyzed reactions of diene-enes/diene-ynes and carbon monoxide (CO) to deliver [4+2+1] cycloadducts, rather than the kinetically favored [2+2+1] products, is challenging. Here, we report that this can be solved by adding a cyclopropyl (CP) cap diene moiety original substrates. The resulting cyclopropyl-capped diene-ynes/diene-enes react with CO under Rh catalysis give cycloadducts exclusively without forming products. This reaction has broad scope used...
