Abstract: Described herein are methods, devices, and systems for identifying a subset of a plurality of features, using one or more feature importance metrics, for training and using a homologous repair deficiency (HRD) classification model. Further described are methods, devices, and systems for classifying a tumor of a cancer, such as pancreatic cancer, as likely HRD positive or likely HRD negative, and for calling the tumor as HRD positive or HRD negative.

Abstract: A safety blind assembly has a rail, a shade, medium slats, a bottom slat, cords and a safety device. The shade is attached to a bottom edge of the rail. The medium slats and the bottom slat are separately mounted on the shade. The safety device has releasable rings and detachable connectors. The releasable rings are mounted on the medium slats and the detachable connectors are mounted on the bottom slat. The cords are mounted in the rail, pass through the releasable rings and are connected to the detachable connectors. When someone is wrapped with the cord and the cord is pulled outward from the shade, and the cord can be released from the releasable ring to loosen the cord to provide the first safety measure. If a pulling force of the cord exceeds a predetermined detach force, the detachable connectors detach to provide the second safety measure to avoid injury.

Abstract: A window blind has a rail, a shade, multiple guide rings, multiple release brackets and multiple cords. The shade is connected to the rail and has a bottom slat and multiple intermediate slats. The guide rings are mounted on the shade between two adjacent intermediate slats. The release brackets are mounted on the bottom slat and each has a release mount and a resilient clip. The release mounts are attached to the bottom slat and a corresponding resilient clip is detachably mounted in the release mount. The cords are mounted through the rail and each cord passes through corresponding guide rings and connects to the resilient clip of a corresponding release bracket. The release bracket separates above a predetermined force so reduces a choking hazard to pets and children and prevents damage to blinds caused by high winds or incorrect operation.
