Immunoglobulin (Ig) G4-related diseases are very rare diseases and are difficult to diagnose and treat.Here, we report a rare condition, an IgG4-related disease involving the bilateral renal pelvises, which was successfully treated with steroid therapy.A 64-year-old female was admitted with left flank pain and hematuria.Computed tomographic images
Sentiment classification has become a significant research topic in natural language processing.As the most popular research method of sentiment classification, deep learning has been applied to various experimental datasets by numerous scholars.However, sentiment classification suffers from a number of drawbacks including poor effect and insuffici
A neural network embedding learning control scheme is proposed in this paper, which addresses the performance optimization problem of a class of nonlinear system with unknown dynamics and disturbance by combining with a novel nonlinear function approximator and an improved disturbance observer (DOB).We investigated a mixture basic function (MBF) to
Insects enhance aerodynamic flight control using the dynamic movement of their appendages, aiding in balance, stability, and manoeuvrability.Although biologists have observed these behaviours, the phenomena have not been expressed in a unified mathematical flight dynamics framework.For instance, relevant existing models tend to disregard either the
Numerous dromaeosaurid taxa recovered from the Upper Cretaceous strata of the Gobi Desert raise questions over niche partitioning among closely related species.Here, I describe a dromaeosaurid specimen from the Baruungoyot strata of the Khulsan locality, containing a partial skull in close association with the left hind limb.The material can be ref
