Served my country in the 80s-90s. Proud husband and father. Always asking questions. Looking for the truth.
Detection of norovirus virus-like particles (VLP) by total internal reflection fluorescence (TIRF). a) Schematic representation of the sandwich assay setup. The particles are captured onto a bilayer containing 10% H type 1 glycosphingolipids (GSL) recognizing the VLPs with high specificity. The fluorescent signal is generated by TIRF illumination of the sensor-bound rhodamine-labeled vesicles containing 5% H type 1 GSL. b) A representative microscopy image of surface-bound vesicles i) on a bilayer incubated with 12.5 pM VLPs and ii) on a negative control performed in absence of VLPs. Scale bars: 50 μm.
A pulse wave can be created by subtracting a sawtooth wave from a phase-shifted version of itself. ... A single ramp wave (sawtooth or triangle) applied to an input of a comparator produces a pulse wave that is not bandlimited. A voltage applied to the other input of the comparator determines the pulse width.
Simulated magnetic RF-field and local SAR distributions in phantom: (a) odd mode of dual-mode dipole; (b) even mode of dual-mode dipole; (c) loop of reference coil; (d) dipole of reference coil. Color plots demonstrate B + 1 magnitude normalized by square root of accepted power. Arrows represent directions of H-field vector Insets local SAR distributions at 1W of accepted power.
