Abstract: A method for surgical segment selection in adolescent idiopathic scoliosis (AIS) assisted by deep learning is provided, the method comprises: acquiring a clinical case image, annotating positions and types of a surgical fixation segment and a non-fixated segment in thoracic vertebrae and lumbar vertebrae in the clinical case image, and training a network model; inputting a spinal image of a patient into the trained network model, wherein the network model segments the spinal image according to learned image features, divides the spinal image into different regions, and outputs a predicted type and a confidence for each region; correcting the confidence by a process of position correction.

Abstract: Embodiments are provided for balancing storage resources in a distributed database. According to certain aspects, various hardware components may facilitate a three-stage technique including a node balancer technique, a shard balancer technique, and a replica balancer technique. The node balancer technique may create a set of pods from a set of nodes residing across a set of storage racks. The shard balancer technique may redistribute, among the set of pods, a portion of a set of shards assigned to respective pods of the set of pods. The replica balancer technique may, for each pod, distribute the set of replicas so that the replicas reside across the storage racks of that pod.
