Abstract: A pulse voltage conditioning method of a vacuum interrupter with automatic conditioning energy adjustment based on a trend of a breakdown voltage of the vacuum interrupter during a conditioning process. A current-limiting resistor and a parallel capacitor are automatically adjusted to ensure the conditioning energy reaching a critical value without deconditioning effect. The critical value refers to a maximum conditioning energy without damaging the electrode surfaces, namely an optimal conditioning energy, which can better remove insulation defects on the electrode surface and improve insulation performance of a vacuum gap. The problems of insufficient conditioning and deconditioning effect during conventional voltage conditioning process of the vacuum interrupter can be solved. Therefore, insulation strength of the vacuum interrupter can be raised to a higher level through conditioning.

Abstract: An approach to optimize performance for large scale inference models. Data in the form of images is received from sensors such as cameras.

Based on the embedded delivery time and frequency, the portioned images are delivered to the appropriate inference models.

The approach assigns priorities to each of the data fields included in the data record based on a priority assessment of the respective data fields. The approach then sends, to a data receiver, a subset of the plurality of data fields based on the assigned priority.

Abstract: Human skeletal muscle stem cells were generated from facioscapulohumeral muscular dystrophy (FSHD) and healthy control iPSC using a transgene-free skeletal muscle differentiation protocol and production of stable iMyoblasts. Analyses revealed that FSHD and healthy control iMyoblasts are embryonic-like myogenic cells that undergo myotube differentiation ex vivo by growth factor depletion and are efficiently transplantable into the tibialis anterior (TA) muscles of NSG mice, where human muscle under-goes embryonic-to-adult myosin isoform switching. The DUX4 FSHD disease gene maintains its hypomethylated disease state inFSHD iPSC and iMyoblast, and its expression is upregulated during myotube differentiation and in muscle xenografts. Consequently, these iMyoblasts accurately exhibit the molecular pathology of human muscular dystrophies and are useful for the development of drug, gene editing and stem cell therapeutics.
