In this letter, we present a neural field-based real-time monocular mapping framework for accurate and dense Simultaneous Localization Mapping (SLAM). Recent frameworks show promising results, but rely on RGB-D or pose inputs, cannot run in real-time. To address these limitations, our approach integrates dense-SLAM with implicit fields. Specifically, SLAM runs parallel tracking global optimization, while map is constructed incrementally based the latest estimates. For efficient construction...
The cross section for one-proton knockout from $^{16}\mathrm{C}$ with a large neutron-proton separation energy asymmetry on carbon target has been measured at an intermediate beam of around 240 MeV/nucleon. is compared to the predictions based eikonal reaction model shell-model structure inputs. beam-energy dependence reduction extracted spectroscopic strength strongly bound nucleon removal derived combining existing intermediate-energy data present measurement. deduced factor ${R}_{s}$,...
This study aimed to develop and validate an AI (artificial intelligence)-aid method in myocardial perfusion imaging (MPI) differentiate ischemia coronary artery disease.We retrospectively selected 599 patients who had received gated-MPI protocol. Images were acquired using hybrid SPECT-CT systems. A training set was used train the neural network a validation test predictive ability of network. We learning technique named "YOLO" carry out process. compared accuracy with that physician...
Organic aerosols (OA) are an important component of fine particulate matter (PM2.5), constituting a substantial portion its total mass. Seasonal ambient PM2.5 samples were collected in Xi’an from April 2018 to March 2019. In order achieve molecular-level understanding the OA fraction, analyzed using iodide chemical ionization mass spectrometer combined with Filter Inlet for Gases and AEROsols (FIGAERO-CIMS). The sum compounds identified by FIGAERO-CIMS represented 29% organic on...
The Inner Mongolia East Ujimqin Banner - Liaoning Donggou geological section is located in Northeast China, spanning two primary tectonic units: the Xing'an-Mongolia Orogenic Belt and North China Craton. Since Paleozoic era, has experienced multiple phases of activity, accompanied by significant lithospheric changes reconstruction its material structure. Investigating thermal structure differences lithosphere between Belt, Yanshan Liaodong Uplift crucial for understanding mechanisms deep...
Text-guided Video Temporal Grounding (VTG) aims to localize relevant segments in untrimmed videos based on textual descriptions, encompassing two subtasks: Moment Retrieval (MR) and Highlight Detection (HD). Although previous typical methods have achieved commendable results, it is still challenging retrieve short video moments. This primarily due the reliance sparse limited decoder queries, which significantly constrain accuracy of predictions. Furthermore, suboptimal outcomes often arise...
In the magnetic field measurement of accelerator magnets, efficient and accurate positioning system magnet is a critical process. By analyzing mechanical structure working principle harmonic coil system, an automatic technology proposed in this research for high-precision fast multipole system. Through special design comprehensive application multi-camera photogrammetry control six-degree-of-freedom (6DoF) attitude adjustment non-contact can be realized. The operation scheme not only save...
Heavy ion therapy is currently recognized as the most advanced cancer radiotherapy approach in world. This article introduces a high-precision and non-contact measurement method based on close-range photogrammetry combined with 3D control network of laser tracker, which used to guide positioning real-time target area monitoring for patients undergoing heavy radiotherapy. By precise connection between tracker digital device, we position system absolutely at treatment isocenter, measuring...
Vision Transformers (ViTs) have revolutionized the field of computer vision, yet their deployments on resource-constrained devices remain challenging due to high computational demands. To expedite pre-trained ViTs, token pruning and merging approaches been developed, which aim at reducing number tokens involved in computation. However, these methods still some limitations, such as image information loss from pruned inefficiency token-matching process. In this paper, we introduce a novel...
