  • Publication number: 20250104828
    Abstract: A method and system for evaluating a treatment using one or more model parameters associated with a quantitative systems pharmacology (QSP) system. Input data corresponding to a treatment is received. The input data is sent to a machine learning system that has been trained, the machine learning system representing at least a portion of the QSP model. The machine learning system is used to generate a set of values for a set of treatment effect parameters associated with the QSP model. A final output is generated based on an evaluation of the treatment on a subject using the set of values for the set of treatment effect parameters.

  • Publication number: 20220172812
    Abstract: A method for predicting pharmacokinetic-pharmacodynamic effects over time is provided. A pharmacokinetic pathway of a neural network system that lies at least partially within an ordinary differential equations (ODE) module of the neural network system is trained to generate a dose effect output associated with a drug. A pharmacodynamic pathway of the neural network system that lies at least partially within the ODE module is trained to generate a drug effect output associated with the drug. The drug effect output associated with an administration of the drug over a time period is predicted using the neural network system.

  • Patent number: 11074397
    Abstract: Described herein are techniques for adding adaptive annotations to an electronic content item. For example, a user may insert an annotation by hand drawing the annotation over the content of the content item, in white space around the content, or within an annotation window. The user may also anchor, associate, or link annotations to particular portion of the content item, such that when the content is displayed or rendered on a display of an electronic device, the annotation appears in-line with the content and adjacent to the associated portion.

  • Publication number: 20200107112
    Abstract: A single-magnet double-tone-circuit coaxial loudspeaker includes a shell, a U iron, a magnet, a spring washer, a first diaphragm assembly, a second diaphragm assembly, an upper cover and a terminal plate. A single “magnet+spring washer+U iron” magnetic circuit is extended to be two upper-lower coaxial magnetic circuits, therefore, the first diaphragm assembly and the second diaphragm assembly which are electrically connected to the terminal plate generate a double-magnetic-circuit feature by sharing a single-magnet system. High frequency and low frequency wave bands are driven independently, such that high frequency and low frequency portions can achieve a better sound resolution effect. The complementation of the two reduces distortion, thus improves the overall acoustic performance of the loudspeaker.
