Target detection algorithm for basketball robot based on IBN-YOLOv5s algorithm.

Being able to quickly and accurately detect and recognize target balls is a key task for basketball robots in automated and intelligent sports competitions. This study aims to propose an effective target detection method for basketball robots, which is based on the improved YOLOv5s model and introduces spatial pyramid pooling and instance-batch normalization structure. The study first pre-trained the model and compared the migration training with the random initialization approach.

Unsupervised speckle denoising in digital holographic interferometry based on 4-f optical simulation integrated cycle-consistent generative adversarial network.

The speckle noise generated during digital holographic interferometry (DHI) is unavoidable and difficult to eliminate, thus reducing its accuracy. We propose a self-supervised deep-learning speckle denoising method using a cycle-consistent generative adversarial network to mitigate the effect of speckle noise. The proposed method integrates a 4-f optical speckle noise simulation module with a parameter generator.

FOXM1 contributes to docetaxel resistance in castration-resistant prostate cancer by inducing AMPK/mTOR-mediated autophagy.

Docetaxel-mediated chemotherapy is the first line therapy for metastatic castration-resistant prostate cancer (CRPC) patients, but its therapeutic benefit is limited by the development of resistance. Although Forkhead box protein M1 (FOXM1) has been implicated in prostate tumorigenesis and metastasis, its role in docetaxel resistance has not been studied. Here, we showed that FOXM1 expression was upregulated in the docetaxel resistant CRPC cell lines (PC3-DR and VCaP-DR) and knockdown of FOXM1 sensitized the cells to docetaxel both in vitro and in vivo.

Computer-assisted orthognathic surgery combined with fibular osteomyocutaneous flap reconstruction to correct facial asymmetry and maxillary defects secondary to maxillectomy in childhood.

Maxillectomy in childhood not only causes composite primary defects but also secondary malformation of the middle and lower face.
