Abstract: Communication systems are described that use signal constellations, which have unequally spaced (i.e. ‘geometrically’ shaped) points. In many embodiments, the communication systems use specific geometric constellations that are capacity optimized at a specific SNR. In addition, ranges within which the constellation points of a capacity optimized constellation can be perturbed and are still likely to achieve a given percentage of the optimal capacity increase compared to a constellation that maximizes dmin, are also described. Capacity measures that are used in the selection of the location of constellation points include, but are not limited to, parallel decode (PD) capacity and joint capacity.

Abstract: Communication systems are described that use signal constellations, which have unequally spaced (i.e. ‘geometrically’ shaped) points. In many embodiments, the communication systems use specific geometric constellations that are capacity optimized at a specific SNR, over the Rayleigh fading channel. In addition, ranges within which the constellation points of a capacity optimized constellation can be perturbed and are still likely to achieve a given percentage of the optimal capacity increase compared to a constellation that maximizes dmin, are also described. Capacity measures that are used in the selection of the location of constellation points include, but are not limited to, parallel decode (PD) capacity and joint capacity.

Abstract: Communication systems are described that use unequally spaced constellations that have increased capacity compared to conventional constellations operating within a similar SNR band.

Abstract: Embodiments of the present disclosure relate to the field of ammunition rounds for training or tactical purposes. In one or more embodiments, the projectile is equipped to transmit an improved visual signature upon impact, including one or both of flash and smoke signatures. In one example, a projectile includes a projectile body, an ogive coupled to the projectile body, and a boat tail having a degree of transparency coupled to the projectile body. The boat tail having a degree of transparency and the projectile body define a cavity within the boat tail having a degree of transparency and the projectile body. A flash producing material is disposed within the cavity.

Abstract: Disclosed herein are lock assemblies that include, in particular embodiments, a cable assembly, a housing, a sensor assembly, and a wireless transceiver. The cable assembly includes a cable having a sensor element disposed along its length, a first shackle pin on its first end, and a second shackle pin on its opposing end. The housing defines a first pinway for receiving the first shackle pin, a second pinway for receiving the second shackle pin, and a locking mechanism for securing the shackle pins to the housing. The sensor assembly is located within the housing and in communication with the cable assembly for sensing a cable type and a cable condition related to the cable assembly. The wireless transceiver is connected to a power source, in communication with the sensor assembly, and operated by a microcontroller within the housing.

Abstract: A method for magnetic resonance imaging (MRI)-guided interstitial thermal therapy includes receiving MRI data for tissue of a patient, generating an apparent diffusion coefficient (ADC) map from the MRI data, identifying a target site for thermal therapy based on the ADC map, wherein the target site is a tumor identified by low ADC values on the ADC map, planning the thermal therapy for the target site including identifying a plurality of individual localized areas to be ablated during delivery of the thermal therapy, the plurality of individual localized areas having the lowest ADC values among the low ADC values within the target site, activating a laser to deliver the thermal therapy to the plurality of individual localized areas using a laser fiber, and monitoring progress of the thermal therapy using MR thermometry.

Abstract: Methods for generating immune responses using adenovirus vectors that allow multiple vaccinations with the same adenovirus vector and vaccinations in individuals with preexisting immunity to adenovirus are provided.

Abstract: Embodiments of the disclosure provide a system and method of allocating a resource based on myriad input data. In some embodiments, the myriad input data include membership information, claims data, transactional data, etc. The myriad input data are sorted and organized in a meaningful association relationship before applied to a resource allocation modeling algorithm. The resource allocation modeling algorithm provides estimated resource necessary for the application chosen. For example, an insurance company may use membership information, claims data, transactional data, etc., to estimate how much reserves or funds it should hold to cover future claims within a certain timeframe.

Abstract: A vehicle includes a body defining an interior cabin having at least one seat and a tailgate rearward of the at least one seat at a rear end of the cabin interior, a shelf configured to extend between lateral sides of the cabin interior in a region between the at least one seat and the liftgate. The shelf is configured to be arranged in one of a first shelf position, a second shelf position and a seat backrest position, and a heating device operable to heat the shelf. The vehicle also includes an orientation sensor to sense orientation of the shelf in one of the first position, second position and backrest position, and a controller controlling temperature of the heating element based on the sensed orientation of the shelf.

Abstract: Microbiota restoration therapy (MRT) compositions (e.g., oral MRT compositions) and methods for manufacturing MRT compositions are disclosed. An example method for manufacturing an MRT composition may include collecting a stool sample, purifying the stool sample to form a purified sample, stabilizing the purified sample to form a stabilized sample, converting the stabilized sample to a solid, adding one or more additives and/or excipients to the solid to form a treatment composition, and encapsulating the treatment composition.
