BAF-Net: Bidirectional attention fusion network CNN and transformers for the pepper leaf segmentation.

The segmentation of pepper leaves from pepper images is of great significance for the accurate control of pepper leaf diseases. To address the issue, we propose a bidirectional attention fusion network combing the convolution neural network (CNN) and Swin Transformer, called BAF-Net, to segment the pepper leaf image. Specially, BAF-Net first uses a multi-scale fusion feature (MSFF) branch to extract the long-range dependencies by constructing the cascaded Swin Transformer-based and CNN-based block, which is based on the U-shape architecture.

High-throughput RNA-sequencing reveals novel targets of tofacitinib in the treatment of rheumatoid arthritis.

The Association of Neuronal Stress with Activating Transcription Factor 3 in Dorsal Root Ganglion of in vivo and in vitro Models of Bortezomib- Induced Neuropathy.

Background: The notion that proteasome inhibitor bortezomib (BTZ) induced intracellular oxidative stress resulting in peripheral neuropathy has been generally accepted. The association of mitochondrial dysfunction, cell apoptosis, and endoplasmic reticulum (ER) stress with intracellular oxidative stress is ambiguous and still needs to be investigated. The activation of activating transcription factor 3 (ATF3) is a stress-hub gene which was upregulated in dorsal root ganglion (DRG) neurons after different kinds of peripheral nerve injuries.
