Abstract: A method of automatic identification of PCIe configuration of a server and preventing operation if each slimline connector connected with a PCIe device is found connected to an incorrect slot of a mother board utilizes a combination of first and second signals of two null interfaces of the first connector as that ID signal and a combination of third and fourth signals of the two interfaces of a second connector as that ID signal. The CPLD receiving the ID signals detects whether the first and second slimline connectors are in their specified and correct slots. Powering on of computer is not permitted if incorrect connection is found, and a warning prompt is generated. A PCIe channel width for each slimline is automatically configured if no incorrect connection is found. A server applying the method is also disclosed.

Abstract: The present invention provides a TNA-based probe for detecting and imaging a target miRNA in living cells. TNA-based probe is composed of a fluorophore-labeled TNA reporter strand partially hybridizing to a quencher-labeled TNA recognition strand which is designed to be antisense to the target RNA transcript via pair pairing. Upon cellular entry without the need of harmful transfection treatment, the quencher-labeled TNA recognition strand binds to targeted transcript, and these target binding events displace the reporter strand from the quencher, resulting in a discrete “turning-on” of the fluorescence. The extent of fluorescence enhancement is quantifiably related to the target RNA expression level. Additionally, the TNA-based probe shows rapid detection response, excellent selectivity and specificity toward target miRNAs and is able to distinguish the target molecules with 1-2 base mismatches.

Abstract: Data augmentation is described to train an artificial intelligence model that includes analyzing a first data set to measure an amount of data in the data set and the variation in the amount of data in the first data set to determine deficiencies for training an artificial intelligence model. Augmenting data is added for the first data set having an amount of data measured that fails to meet a threshold value. Deficiencies in the variation in the amount of data in the first data set are augmented using augmentation methods outside the variation scope of the first data set to provide a second data set of augmented data. An artificial intelligence model is trained with a combined data set of the first data set, and the second data set of augmented data when the first and second data set have an amount of data meeting the threshold value.
