Abstract: Air purification devices are described. Devices are powered to form an electric field along an airflow path that creates a plasma for destruction of pathogens carried through the device. Devices can be single-user, portable devices for purification of air flow to and/or from a single user.

Abstract: Single-stranded oligonucleotide probes, systems, kits and methods for chromosome enumeration, gene copy enumeration, or tissue diagnostics. The probes are particularly suited for detecting gene amplification, deletion, or rearrangement in tissue samples in a single, dual, or multiplexed assay. The probes exhibit improved performance compared to industry leading dual-stranded probes; particularly in terms of the rate of hybridization.

Abstract: The present disclosure relates to aerosol delivery devices and related methods of delivering aerosol to a user. The aerosol delivery devices may include a housing providing multiple aerosol pathways having a mouth-end opening through which aerosol can be inhaled by a user, the housing defining a first aerosol delivery pathway in fluid communication with the mouth-end opening and a second aerosol delivery pathway separate from the first aerosol delivery pathway and in fluid communication with the mouth-end opening. An atomizer including a heating element or piezoelectric element and a liquid transport element in fluid communication with an aerosol precursor composition is provided in fluid communication with the first aerosol delivery pathway. A flavorant-infused material is positioned within the second aerosol delivery pathway and adapted to produce a second aerosol upon contact between the flavorant-infused material and flowing air.

Abstract: A method of continuously manufacturing a cured membrane includes continuously compounding and mixing a vulcanizable rubber composition in a mixing extruder while continuously removing gasses from the vulcanizable rubber composition during mixing with a vacuum. The vulcanizable rubber composition may be continuously extruded to form an extrudate, which may be continuously calendered to form a green membrane. The green membrane may be continuously cured, such as by a hot air conveyor curing system, to form a cured membrane.

Abstract: A coherent optical transmitter includes circuitry connected to a coherent modulator; and a plurality of tunable optical filters (TOFs) connected to one another and connected to an output of the coherent modulator, wherein the plurality of tunable optical filters are configurable to create an effective transfer function having a variable width. The TOFs are cascaded and can be included in discrete form on electro-optic printed circuit boards (PCBs), or integrated in various electro-optic material systems such as in silicon photonics, photonic integrated circuits (PICs), as well as hybrid and other approaches. The advantage of this approach includes improved OSNR in colorless transmitters.

Abstract: A communication system is configured to generate a perturbed signal by perturbing an amplitude of a spectrum of an original signal in one or more spectral regions, and to propagate the perturbed signal through components of the communication system. The communication system is further configured to obtain a measurement of the perturbed signal in a first spectral region of the one or more spectral regions following the propagation of the perturbed signal, and to calculate an estimate of an impairment associated with the communication system based on the measurement.

Abstract: A system is configured to measure (602) a forward error correction (FEC) decoding property (216) associated with applying FEC decoding (214) to FEC-encoded bits or symbols at a receiver device (202) deployed in a communication network (100). The system is configured to provide (606) an assessment of operating conditions of the receiver device based on the FEC decoding property. The FEC decoding property comprises, for example, a distribution of a number of iterations of a FEC decoding operation applied to a plurality of FEC blocks processed within a period of time. In some examples, the FEC decoding property comprises any one of heat, temperature, current, voltage, active clock cycles, idle clock cycles, activity of parallel engines, activity of pipeline stages, and input or output buffer fill level of the FEC decoding. The assessment is based, for example, on a comparison between the FEC decoding property and reference FEC data (218).
