The establishment of left–right (LR) asymmetry is fundamental to animal development, but the identification of a unifying mechanism establishing laterality across different phyla has remained elusive. A cilia-driven, directional fluid flow is important

=-2x-8y,因为\left| x-5 \right|+{{\left( y+4 \right)}^{2}}=0,所以x-5=0,y+4=0,解得x=5,y=-4,所以当x=5,y=-4时,原式=-2\times 5-8\times \left( -4 \right)=-10-32=22.反馈 收藏
We analyzed fundus images to identify whether convolutional neural networks (CNNs) can discriminate between right and left fundus images. We gathered 98,038 fundus photographs from the Gyeongsang National University Changwon Hospital, South Korea, and au
