  • Patent number: 10128801
    Abstract: A detector system for time-of-flight (TOF) positron emission topography (PET) includes an analog silicon photomultiplier (aSiPM) configured to detect at least one photon event. The aSiPM has an anode and a cathode. A transformer has a first side electrically coupled to the aSiPM to form a low-impedance current loop between the anode and the cathode of the transformer. An impedance ratio of the transformer N reduces an effective terminal resistance of the aSiPM. An amplifier is electrically coupled to a second side of the transformer. The amplifier has negative feedback path configured to minimize the voltage swing between a non-inverting input and an inverting input. The negative feedback path reduces an effective terminal capacitance and an effective load impedance of the aSiPM.

  • Patent number: 10102379
    Abstract: Published enterprise threat detection (ETD) security notes are accessed in a computer data store. Applicability of the published ETD security notes are determined for an information technology computing (IT) landscape. A determination is made that a particular applicable ETD security note has not yet been implemented in the IT computing landscape. Aggregated impact of compromise (IoC) and state of compromise (SoC) values associated with the published ETD security note are analyzed and a computing system patching action is performed based on the aggregated IoC and SoC values.

  • Patent number: 10095821
    Abstract: Electronic design automation systems, methods, and computer readable media are presented for the generation of power-related connectivity data by an analog simulator (for example, by propagating the power supply data and/or ground data through the circuit components of the analog design schematic). In some embodiments, the verification module determines consistency between different versions of power-related connectivity data, such as: (i) power-related connectivity data from the analog design schematic and (ii) power-related connectivity data from the power-related data characterizing the mixed-signal design. Such verification determines whether the mixed-signal design satisfies the low power specification as expressed in the power-related data characterizing the mixed-signal design.

  • Publication number: 20180272010
    Abstract: Disclosed is a lymph targeting nuclear magnetic contrast agent using a brown algae polysaccharide as a carrier, and a preparation method and a use thereof. A macromolecular contrast agent with good water solubility was prepared by using the brown algae polysaccharide as the carrier, using mannose or mannose derivatives as a mannose receptor (MBP) recognition group, and using a paramagnetic metal ion chelate as a nuclear magnetic resonance imaging group. The binding capacity of lymphoid tissue was improved. The mannose or mannose derivative group introduced into the synthesized contrast agent molecule achieves the goal of binding to the enriched mannose receptors in the lymphoid tissues.
