Abstract: The present disclosure belongs to the technical field of medical devices, and in particular relates to a post-operative indwelling urinary catheter suitable for males. In view of a problem that a urinary catheter is prone to shaking due to collision, in the present disclosure, by arranging a shield, a limiting ring is rotated to adjust a connection position of a spiral tube and a chassis, and the shield is pushed to cause a fixing soft disk to be abutted against a human body, avoiding the possibility of urethral irritation or injury when an external urinary catheter I is shaken, avoiding bacterial invasion and urinary tract infection, and improving the comfort of use.

The at least two target sub-pixels of a same sub-pixel share the anode of the sub-pixel and are driven by a same pixel driver circuit; and the sub-pixels of at least one color are arranged in a same column of sub-pixels or a same row of sub-pixels.

Abstract: A method for extracting and correcting a ringing component in a dynamic pressure measurement signal of a shock wave flow field includes: adaptively decomposing a dynamic pressure measurement signal of a shock wave flow field through an empirical mode decomposition (EMD) method, and extracting a ringing component in the dynamic pressure measurement signal of the shock wave flow field; constructing a ringing component distortion correction model through a convolutional neural network (CNN) and a dataset through a staggered spanning dataset construction method; and predicting a time series of a segment with mode mixing in the ringing component, to accurately extract a ringing component in a dynamic pressure response signal. The method combines advantages of an adaptive signal decomposition method and a CNN model identification method.

Abstract: Techniques are disclosed for maintaining a network graph by updating labels in the graph based on features generated using at least two different feature extraction procedures. A server system accesses a machine learning model trained using features generated using multiple feature extraction procedures. Using the model, the system determines labels for unlabeled nodes in a network graph whose nodes correspond to entities and whose edges correspond to electronic communications executed between the different entities, where the determining is performed based on output of the model for values of the features corresponding to the unlabeled nodes. Based on the determining, the system updates the graph by assigning the determined labels to the unlabeled nodes in the graph. The system performs, based on the assigned labels indicating that behavior of entities corresponding to the nodes are anomalous, preventative actions for entities corresponding to the nodes with assigned labels.

Abstract: Techniques are disclosed for generating multiple different types of new features from a network graph and training a machine learning model using the newly generated features. A server system generates, from electronic communications, a network graph that includes nodes and edges. The server captures snapshots of the network graph that include nodes and edges existing at different time intervals. The system generates, for nodes included in respective snapshots, different types of features that include a neighbor convolution feature for a given node in a given snapshot by compressing node behavior features for neighbor nodes of the given node that are one hop away from the given node within the given snapshot of the network graph. The system trains, using the plurality of different types of features, a machine learning model usable to predict whether unlabeled nodes in the network graph are anomalous.

Abstract: Embodiments herein describe correcting nonlinearity in a Digital-to-Time Converter (DTC) by relaxing a DTC linearity requirement, which results in the correction being co-adapted with a DTC gain calibration loop which can operate in parallel with a DTC integral nonlinearity (INL) correction loop. In one embodiment, the DTC gain calibration loop and the DTC INL correction loop are constrained when determining a nonlinearity correction code to improve the likelihood they converge. Once determined, the nonlinearity correction code can be combined with an digital code output by a time-to-digital converter (TDC) to generate a phase difference between a reference clock and a feedback clock.
