Abstract: Audio signals, collected with equipment commonly available to individuals (e.g., a mobile device), can be used to analyze a patient's breathing. An audio signal associated with the patient's breathing for a time period can be detected with the mobile device and used to approximate the patient's respiratory flow for the time period. For example, the audio signal can be analyzed by determining a representation of an audio frequency of the audio signal, splitting the audio frequency of the audio signal into distinct time steps, determining points comprising a weighted mean frequency at each time step, applying a frequency-to-flow rate linear transformation at each time step to approximate the respiratory flow versus time, and plotting a graphical representation of the respiratory flow versus time. The respiratory flow for the time period can be tagged with a factor related to the patient and saved in a database for future analysis.

Abstract: A thermal accelerant can be used as a drug delivery vehicle to deliver one or more drugs to a target site. For example, in some embodiments, a carrier such as albumin or human serum albumin (HSA) can be impregnated with, or covalently attached to, an anti-tumor agent and delivered to a location proximate to a tumor of a patient. The carrier can be exposed to an energy source that structurally alters the carrier and releases the agent therefrom. The sources of energy can include one or more of microwave, radiofrequency, electrical pulse (electroporation) or sonar (HIFU or histotripsy). In some embodiments, the anti-tumor agent can be delayed release such that a portion of the agent is released from the carrier over an extended period of time. The incorporation of an anti-tumor agent in a thermal accelerant provides a thermal ablation-drug delivery combination therapy (e.g., a thermally-activated combination therapy).

Abstract: Aspects of the invention are associated with the discovery of processes for converting methane (CH4), present in a methane-containing feed that may be obtained from a variety of sources such as natural gas, to higher hydrocarbons (e.g., C2+ hydrocarbons) such as C2 hydrocarbons (e.g., ethane, ethylene, and acetylene) and aromatic hydrocarbons (e.g., benzene, one or more C1- or C2-substituted benzenes, and/or one or more fused ring aromatic hydrocarbons). Representative processes involve direct, non-oxidative methane conversion (NOMC), such that the need for an oxidant to form CO as an intermediate may advantageously be avoided. This reduces overall complexity and the tendency to promote unwanted side reactions that reduce hydrocarbon yields and lead to CO2 production.

Abstract: Methods for the encoding an encryption key for secure storage are disclosed. The methods rely on the use of unclonable, one-way functions, such as images of biological objects that may be measured according to challenges to result in responses. A biometric print of a biological object is measured with a set of n challenges resulting in n responses. The responses are an ordered sequence, with each response having a fixed position in the sequence. A key is generated of bit length n. A subset of m responses in the full set of n responses is selected, where the selected responses correspond to positions of is in the key. The response subset is stored. The key is then used, and deleted. A party wishing to re-generate the key generates the same set of challenges, measures the same biological object with the challenges a second time, and generates a second set of n responses.

A neural decoding system can: receive a neural signal from a neural recording device, identify that the neural signal is representative of the user at least thinking of attempting to perform a gesture, which is one of a plurality of known gestures mapped to a plurality of commands, and output a command based on the gesture (the gesture is mapped to the command). A controller can be in communication with the neural decoding system and a display. The controller can: receive the command, if the gesture is a primary gesture, then select a group to be an active group of elements, if the gesture is a secondary gesture, then at least select an element of the active group of elements and output a response indicative of the group being activated and/or the element being selected.
