Abstract: An aerosol spirometer and a method of operating an aerosol spirometer. Comparison of lung function data that has been acquired by the aerosol spirometer to a known, idealized exhalation aerosol concentration profile of healthy lung operation may be used to fill in missing lung function data that arises out of resistance-based and compliance-based inhomogeneities in both aerosol penetration and aerosol deposition, where the inhomogeneities may be mathematically correlated to time constant data that in turn may be directly correlated to ventilation. This data, when added to the idealized exhalation aerosol concentration profile, produces a more complete data-informed exhalation aerosol concentration profile from which an inference may be made about possible lung dysfunction of an individual using the aerosol spirometer. A machine learning model may be trained on the lung function data to provide a predictive inference related to either an onset or worsening of the lung dysfunction.

Abstract: A computer-implemented method, system and computer program product for dynamically providing a typing feedback indicator. Text entered in a body of a message that is to be sent to a recipient is detected. Prior to the user (author) sending the message to the recipient, the text of the message being composed by the user is analyzed to determine a sentiment and an emotion as well as to determine a topic of the content of the text. Based on such analyses, as well as possibly based on other criteria, a typing feedback indicator is generated to reflect an indication of the content of the message to be sent to the recipient. The typing feedback indicator may then be displayed on a computing device of the recipient while the user (author) is composing the message thereby providing the recipient context awareness of the message prior to receipt of such a message.

Abstract: The exemplary embodiments disclose a system and method, a computer program product, and a computer system for diagnosing technical issues. The exemplary embodiments may include collecting data relating to one or more technical issues, extracting one or more features from the collected data, determining one or more diagnoses based on the extracted one or more features and one or more models, and suggesting to a support agent one or more actions based on the one or more determined diagnoses.

Abstract: A system, computer program product, and method are provided to conduct gap probability mapping to predict presence and location of one or more gaps in a corpus. A probabilistic model is formed to represent inter-corpora associations of objects, which the model leverages to process query submissions. As queries are received and processed, the model creates an adjustment. Subject to evaluation, confidence of the adjustment is evaluated, and a response correlated to the confidence is returned.

Abstract: The Nebulized Airborne Biohazard Stage Alert (NABSA) is a method utilizing an optical particle counter in conjunction with a fluorometer as triggers to detect and assess potential biohazard threats infused into surrounding air. In the first stage an optical particle counter is constantly passing sampled air in front of an energy source, in turn scattering light. This scattered light is evaluated to establish if the particles are above one micrometer in concentrations, and thus potentially an aerosolized threat. Such detection triggers the secondary stage in which the sample particles are tested for viability via processing through a dye with fluorescent properties affected when bonded with an entity universally found in all biological substances and a UV light source. The detection of concentrations of oversized, viable particles triggers the third stage to compare a sample of the particles to known biowarfare agents to delineate the specific agent species.
