Abstract: A flexible multi-path RF adaptive tuning network switch architecture that counteracts impedance mismatch conditions arising from various combinations of coupled RF band filters, particularly in a Carrier Aggregation-based (CA) radio system. In one version, a digitally-controlled tunable matching network is coupled to a multi-path RF switch in order to provide adaptive impedance matching for various combinations of RF band filters. Optionally, some or all RF band filters include an associated digitally-controlled filter pre-match network to further improve impedance matching. In a second version, some or all RF band filters coupled to a multi-path RF switch include a digitally-controlled phase matching network to provide necessary per-band impedance matching. Optionally, a digitally-controlled tunable matching network may be included on the common port of the multi-path RF switch to provide additional impedance matching capability.

Abstract: Disclosed herein is a particle comprising a magnetic material and a carbon layer on the outer surface of the magnetic material. The carbon layer may comprise graphite, such as Graphite from the University of Idaho Thermolyzed Asphalt Reaction (GUITAR). The particle may further comprise a single stranded nucleic acid moiety, such as single stranded DNA or single stranded RNA, conjugated to the carbon layer. The disclosed particles are useful as nucleic acid sensors, PCR reagents, and in nucleic acid synthesis applications.

Abstract: Methods, systems, and devices for wireless communication are described. A first user equipment (UE) may receive link capability information from a second UE that has a cellular wireless connection with a network entity of a cellular wireless network. The link capability information may be associated with a subscription of the second UE to the cellular wireless network. The first UE may establish a local wireless connection with the second UE based on the link capability information associated with the subscription of the second UE to the cellular wireless network. The first UE may communicate one or more messages with the network entity of the cellular wireless network via the second UE using first subscriber identity module (SIM) credentials of the first UE or second SIM credentials of the second UE based on establishing the local wireless connection with the second UE.

Abstract: Antimony dithiocarbamate is known to provide extreme pressure (EP) protection in lubricating compositions, such as grease. However, there is a desire to reduce the amount of antimony used in such compositions, while still maintaining acceptable EP performance. It has now been found by using small amounts of either ammonium dithiocarbamate or zinc dithiocarbamate in combination with the antimony dithiocarbamate (SbDTC), a lower amount of SbDTC can be used in the lubricating composition while still maintaining excellent or exceptional EP protection. To counteract the corrosive effects of the SbDTC and ammonium dithiocarbamate composition, it has been found that compounds containing a carboxylic acid group are effective in avoiding copper corrosion.

Abstract: Method and system aspects for integrated automatic exposure control for portal imaging in radiotherapy are described. In an exemplary method aspect, the method includes controlling scanning and blanking of a target of a camera pick-up tube to capture an initial image, and analyzing the initial image to establish an initial image intensity. The method further includes utilizing the initial image intensity to determine a time for scanning a next image, and combining a scan of the next image with the initial image to produce a portal image with a maximized signal to noise ratio.
