We study the problem of extracting correspondences between a pair point clouds for registration. For correspondence retrieval, existing works benefit from matching sparse keypoints detected dense points but usually struggle to guarantee their repeatability. To address this issue, we present CoFiNet - Coarse-to-Fine Network which extracts hierarchical coarse fine without keypoint detection. On scale and guided by weighting scheme, our model firstly learns match down-sampled nodes whose...
Background Smartphone-based online education gained popularity during and after the COVID-19 pandemic. Although recent studies have highlighted association between problematic smartphone use (PSU) mental health symptoms, potential role of learning in this relationship remains unclear. This study aimed t o analyze relationships higher modes, PSU, related psychological symptoms university students. Methods A total 1,629 Chinese students from five provinces completed a web-based questionnaire...
Heralded single photon source (HSPS) is an important way in generating genuine photon, having advantages of experimental simplicity and versatility. However, HSPS intrinsically suffers from the trade-off between heralded rate purity. To overcome this, one can apply multiplexing technology different degrees freedom to enhance performance HSPS. Here, by employing spectral active feed-forward manipulating, we demonstrate a at 1.5 {\mu}m telecom-band. Our results show that effectively erases...
Compared to traditional metal cable, high-temperature superconductor (HTS) cable is a promising candidate for the energy transmission in space solar power stations due its great advantage high density and efficiency. These cables can reduce losses simplify conventional by eliminating need voltage conversion equipment, thus reducing launch weight costs of spacecraft. This paper analyzes feasibility superconducting spacecraft transfer. Addressing operating conditions vacuum cryogenic...
This paper proposes a hybrid Chinese named entity recognition model based on multiple features. It differentiates from most of the previous approaches mainly as follows. Firstly, proposed Hybrid Model integrates coarse particle feature (POS Model) with fine (Word Model), so that it can overcome disadvantages each other. Secondly, in order to reduce searching space and improve efficiency, we introduce heuristic human knowledge into statistical model, which could increase performance NER...
Abstract Tropical cyclones (TCs), especially landfalling intense storms often pose serious threats to life and property in coastal areas. Although TC track forecast skill has been improved the past decades, progress of advancing intensity lags that forecast. One possible limiting factor is absence ocean surface waves systems. To better represent interaction underlying ocean, a regional atmosphere‐ocean‐wave coupled model employed this study. Twenty‐one TCs whole year 2013 are retrospectively...
Federated Learning (FL) offers collaborative model training without data sharing but is vulnerable to backdoor attacks, where poisoned weights lead compromised system integrity. Existing countermeasures, primarily based on anomaly detection, are prone erroneous rejections of normal while accepting ones, largely due shortcomings in quantifying similarities among client models. Furthermore, other defenses demonstrate effectiveness only when dealing with a limited number malicious clients,...
This paper proposes a new discriminative training method, called minimum sample risk (MSR), of estimating parameters language models for text input. While most existing methods use loss function that can be optimized easily but approaches only approximately to the objective error rate, MSR minimizes directly using heuristic procedure. Evaluations on task Japanese input show handle large number features and samples; it significantly outperforms regular trigram model trained maximum likelihood...
The recently proposed weak form quadrature element method (QEM) is applied to the buckling analysis of planar frameworks. This starts with approximation integrands in description (variational formulation) a problem. Neither nodes nor number fixed, being adjustable according convergence need. Examples are presented and comparison results finite made demonstrate effectiveness computational efficiency QEM. It shown that QEM suitable for frameworks either varying or constant cross sections.
Transient voltages in the power grid are key for fault analysis of a grid, optimized insulation design, and standardization high-voltage testing method. The traditional measuring equipment, based on electrical engineering, normally has limited bandwidth response speed, which also featured by huge size heavy weight. In this paper, an integrated optical electric-field sensor Pockels effect was developed applied to measure transient conductors non-contact mode. system speed faster than 6 ns...
Locating faults in transmission lines is important for the safety and continuous operation of power systems. The existing fault location methods based on traveling waves mostly use current transformers to obtain transient signals, which requires a direct connection with live therefore brings inconvenience installation, debugging, maintenance. In this article, we propose flexible noncontact approach locating broadband electro-optic field sensors, where system can be easily installed,...

Comparisons made against situ buoys, satellite...
For web content extraction task, researchers have proposed many different methods, such as wrapper-based method, DOM tree rule-based machine learning-based method and so on. To some extent, all these methods ignore the layout information of webpage, although spatial visual cues often plays a very important role in process locating main webpage when browsing. As consequence, throw part away extracting from webpage. In this paper, we present which combines analysis with rule-base it can make...
Hierarchical phrase-based statistical machine translation systems often suffer from a huge rule table. This paper proposed basic and efficient method for table reduction, discarding monotone composed rules. These rules are redundant because they may be monotonically recreated by minimal Experiments show that the is reduced 57%~71% without worsening quality.
