    Abstract: A dry powder delivery device may be configured to provide micronized dry powder particles to airways of a user. The device may include a cylindrical container delimiting a chamber containing at least one magnetically-responsive object, a motor external to said chamber, a magnet external to the chamber and rotatably coupled with the motor, and an outflow member configured to direct airflow to a user. The magnetically-responsive object may be coated with micronized dry powder particles, and the motor may be operable to rotate the magnet about an axis. Rotation of the magnet creates a magnetic field that causes the magnetically-responsive object to move in response to the magnetic field and collide with a side wall of the container to deaggregate the dry powder particles and aerosolize the dry powder in the chamber.

    Abstract: The present invention concerns a method for determining whether brain regions of interest having reversible or irreversible pathology. The method includes acquiring over a predetermined period of time a plurality of magnetic resonance imaging (MRI) images for each brain region of interest; analyzing the MRI images to obtain quantitative measurements of the fractional anisotropy (FA) for each brain region of interest and determining that brain regions of interest have reversible pathology when the measured FA increases and then decreases over the predetermined period of time.

    Abstract: This disclosure describes techniques for analyzing statistical quality of bitstrings produced by a physical unclonable function (PUF). The PUF leverages resistance variations in the power grid wires of an integrated circuit. Temperature and voltage stability of the bitstrings are analyzed. The disclosure also describes converting a voltage drop into a digital code, wherein the conversion is resilient to simple and differential side-channel attacks.
