Kaon Productions Off Nucleons And The Structure of Baryon Resonances
The recent Investigations in the chiral quark model show that kaon
productions of nucleon play an important role in understanding the structure of
baryons. The evidences of a third resonance in the second resonance
region and two narrow states around 2 GeV suggest a set of the molecular type
baryons with hidden strangeness. Confirming these states requires further
theoretical and experimental studies of the strangeness production.Comment: 4 Pages in Latex form. Contributions to the Proceedings of

An Unified Approach To Pseudo Scalar Meson Photoproductions Off Nucleons In The Quark Model
An unified approach to the pseudo scalar meson (, and )
photoproduction off nucleons are presented. It begins with the low energy QCD
Lagrangian, and the resonances in the s- and u- channels are treated in the
framework of the quark model
The duality hypothesis is imposed to limit the number of the t-channel
exchanges. The CGLN amplitudes for each reaction are evaluated, which include
both proton and neutron targets. The important role by the S-wave resonances in
the second resonance region is discussed, it is particularly important for the
and photoproductions.Comment: 31 pages in Latex fil
Multi-strategy Collaborative Optimized YOLOv5s and its Application in Distance Estimation
The increasing accident rate brought about by the explosive growth of
automobiles has made the research on active safety systems of automobiles
increasingly important. The importance of improving the accuracy of vehicle
target detection is self-evident. To achieve the goals of vehicle detection and
distance estimation and provide safety warnings, a Distance Estimation Safety
Warning System (DESWS) based on a new neural network model (YOLOv5s-SE) by
replacing the IoU with DIoU, embedding SE attention module, and a distance
estimation method through using the principle of similar triangles was
proposed. In addition, a method that can give safety suggestions based on the
estimated distance using nonparametric testing was presented in this work.
Through the simulation experiment, it was verified that the mAP was improved by
5.5% and the purpose of giving safety suggestions based on the estimated
distance information can be achieved.Comment: This paper contains 5 pages, 10 figures, and was accepted at 4th
