    摘要: An aerosolization mitigation device is provided. The aerosolization mitigation device can include a negative pressure aerosolization mitigation system. A transparent barrier can form a frame of the system, and a negative pressure can be generated in the internal volume. The device can isolate a patient to allow ambulatory, surgical, and routine care to proceed during periods of higher patient volume or viral transmission. The negative pressure environment mitigates viral transmission to protect healthcare providers and others in the vicinity of the patient from health risks during patient care.

    摘要: Systems, methods, and computer readable storage media for controlling oxidation of a particulate filter (PF) are closed. The oxidation of the PF may be controlled using a PF model. The PF model may be utilized to simulate operations of the PF based on various input data and/or derived data to determine an optimum time for initiating an oxidation event at the PF, and an oxidation event may be initiated at the PF based on the simulating.

    摘要: Methods for producing engineered exosomes and other vesicle-like biological targets, including allowing a target vesicle-like structure to react and bind with immunomagnetic particles; capturing the immunomagnetic particle/vesicle complex by applying a magnetic field; further engineering the captured vesicles by surface modifying with additional active moieties or internally loading with active agents; and releasing the engineered vesicle-like structures, such as by photolytically cleaving a linkage between the particle and engineered vesicle-like structures, thereby releasing intact vesicle-like structures which can act as delivery vehicles for therapeutic treatments.

    摘要: Systems and methods of embodiments provide a feasible approach to implementing Far-Field Radiated Emission Design (FFRED) techniques suitable for simultaneous transmission of radar and communication signals. A set of signals for transmission and a transmission direction for each signal of the set of signals may be determined. The set of signals includes at least a first signal associated with a first transmission direction and a second signal associated with a second transmission direction that is different from the first direction. An optimization problem is configured based on characteristics of an antenna array and the set of signals and then solved to identify a set of waveforms suitable for transmitting the signals. The set of waveforms may include at least two waveforms, each of the at least two waveforms configured for transmission by a different antenna element of the antenna array. The determined waveforms may be coherent in the far-field and suitable for power efficient transmission.

    摘要: In embodiments, a method of forming a membrane electrode assembly comprises pressing a stack comprising a cathode, an anode, a proton exchange membrane between the cathode and the anode, and a porous catalyst layer in contact with the proton exchange membrane, the porous catalyst layer comprising an ionomer, the ionomer coating internal surfaces of pores of the porous catalyst layer, thereby providing internal ionomer-gas interfaces within the porous catalyst layer; for a time, a pressure, and a temperature to bind the ionomer to the proton exchange membrane, whereby steam is generated within the porous catalyst layer. The steam is removed via pores of the porous catalyst layer to increase the hydrophobicity of the internal ionomer-gas interfaces within the porous catalyst layer.

    摘要: A computer vision-based fastener loosening detection approach is described. A first image is captured at a first time and a second image is captured at a second time. A feature-based image registration is performed to create a third image. An intensity-based image registration is performed to create a fourth image. Registration errors are determined based on a comparison of the first and fourth images. A feature enhancement process is performed on the registration errors to determine whether the fastener has loosened between the first time and the second time.
