Abstract: A system and method for generating reports on perfusion blood volume from computed tomography (CT) data acquired from a subject. The method includes receiving multi-faceted CT data acquired from the subject using one of a multi-energy or polychromatic CT acquisition and deriving an iodine concentration in an artery feeding a volume of interest (VOI) in the multi-faceted CT data. The method further includes determining an effective atomic number of a spatial distribution in the VOL calculating a perfused blood volume of the VOI using the iodine concentration and the effective atomic number, and generating a report of the perfused blood volume of the VOI.
Abstract: Methods of profiling the nucleic acid composition of single cells and tools for same. The methods can include isolating a single cell in a liquid droplet, lysing the single cell in the liquid droplet to release template nucleic acid from the cell, amplifying the template nucleic acid in the liquid droplet to generate amplified nucleic acid, and detecting the amplified nucleic acid in the liquid droplet. The methods can be useful for profiling expression patterns and/or detecting genetic characteristics such as single nucleotide polymorphisms. The tools include nucleic acid logic gates, including polymerase-dependent logic gates. The logic gates can perform logical operations such as YES, NOT, AND, OR, AND-NOT, NOT-AND, NOT-OR, EXCLUSIVE-OR, EXCLUSIVE-NOR, and IMPLY. The tools also include microfluidic systems for performing the methods.

Abstract: Described here are systems and methods for monitoring airflow changes in a patient's airway during a medical procedure or as a general patient monitoring tool. Doppler ultrasound signals are acquired from the tracheal wall of the patient and parameters from those Doppler ultrasound signals are compared to baseline parameters. When a threshold change is detected, an alarm can be provided to a user to indicate respiratory compromise, which can include early airway compromise or airway obstruction.
Abstract: Described here are systems and methods for monitoring airflow changes in a patient's airway during a medical procedure or as a general patient monitoring tool. Doppler ultrasound signals are acquired from an anatomical region within the patient's airway (e.g., a tracheal wall, a cricothyroid ligament, other connective or cartilaginous tissue within the trachea, larynx, or pharynx) and parameters from those Doppler ultrasound signals are compared to baseline parameters, which may include inputting Doppler ultrasound signals to a suitably trained deep learning model or other machine learning algorithm. When a threshold change is detected, an alarm can be provided to a user to indicate respiratory compromise and/or failure, which can include early airway compromise, airway failure, and/or airway obstruction.

Abstract: Acoustically mediated pulsed radiation sources, phased arrays incorporating the radiation sources, and methods of using the radiation sources and phased arrays to generate electromagnetic radiation via magnetic dipole emission are provided. The radiation sources are based on a superlattice heterostructure that supports in-phase magnetic dipole emission from a series of magnetic insulator layers disposed along the length of the heterostructure.

Abstract: The present invention provides a cerebrospinal fluid shunt system that monitors the intracranial pressures over a portion of a monitoring cycle to calculate short intervals of drainage for every monitoring cycle necessary to produce the desired pressure correction. The system operates to significantly reduce the time during which draining occurs allowing tissue surrounding the catheter to rebound from the catheter holes returning to its normal position for a sufficient amount of time to recover its normal shape.

Abstract: Modified influenza virus neuraminidases are described herein that improve viral replication, thus improving the yield of vaccine viruses. Expression of such modified neuraminidases by influenza virus may also stabilize co-expressed hemagglutinins so that the hemagglutinins do not undergo mutation or decrease the need for HA binding to cells.

Abstract: Systems and methods for identifying sequence information from measurements made on single nucleic acid molecules are disclosed. The systems and methods can include binding portions of nucleic acid molecules with marker molecules, such as fluorescent molecules and/or intercalating molecules. The marker molecules provide a detectable signal that includes information about the underlying genomic information of the location on the nucleic acid molecule where a given marker molecule is bound. A profile of the detectable signal along a position of the nucleic acid is acquired for multiple different nucleic acid molecules. The PRIMR algorithm processes the data to provide a consensus profile from which a consensus underlying genomic information can be determined.

Abstract: A method of making a filter, the resulting filter, and a method of using the filter to filter proteins from solution are described. The method includes contacting a porous, polymeric substrate with a transfer liquid comprising a solvent(s) and a charged polymeric solute. The transfer liquid and the polymeric substrate have a Hansen Solubility Parameter (“HSP”) distance of from about 10 to about 35. Contacting the polymeric substrate with the transfer solution causes the polymeric substrate to accept the charged polymeric solute by diffusion transfer, thereby yielding a functionalized filter medium. Removal of the transfer liquid from the polymeric substrate traps the charged polymeric solute on the surface of the polymeric substrate.
Abstract: A light modulator and method of forming the same is provided. The light modulator includes a membrane and a tuning electrode in spaced relation to the membrane. A light blocking fluid is received between the substrate and the tuning electrode and a light blocker is positioned between the tuning electrode and a central portion of the membrane. A pinning electrode is disposed between the light blocker and the membrane and is aligned with the central portion of the membrane. An electrostatic generator is configured to selectively apply an electrostatic force on the membrane causing the central portion of the membrane to deform towards pinning electrode causing the light blocking fluid to be displaced from between the membrane and the pinning electrode.
