  • Publication number: 20190233799
    Abstract: This application is directed generally to foot-and-mouth disease virus (FMDV) 3C proteases that have been modified by mutating a polynucleotide sequence coding for the FMDV 3C protease. The modified FMDV proteases exhibit proteolytic activity on FMDV P1 precursor protein and exhibit a reduction in one or more toxic or inhibitory properties associated with an unmodified FMDV 3C protease on a host cell used to recombinantly produce it. Vectors carrying polynucleotides encoding modified FMDV 3C protease sequences can induce production of FMDV virus-like particles in a host cell when expressed in the host cell. The modified FMDV 3C proteases can generally be used to produce immunogenic FMDV preparations capable of inducing an immune response against FMDV.

  • Publication number: 20190204371
    Abstract: An apparatus for detecting low level pulses of millimeter wave electromagnetic radiation has an electromagnetic field receiver including: a receiving antenna configured to receive an input signal at one or more frequencies ranging from 10 GHz to 100 GHz, and a diode detector coupled to the receiving antenna, the diode detector providing an output voltage signal in response to the input signal. The apparatus also has an electronic signal processor. This produces an amplified voltage signal. The electronic signal processor also produces from the amplified voltage signal a reduced bandwidth, unipolar voltage signal proportional to a peak power of the input signal. The electronic signal processor uses this to produce an amplified reduced bandwidth, unipolar voltage signal. At least the electronic signal processor is encased in an electronically shielded housing.

  • Publication number: 20190195988
    Abstract: Various embodiments of the present invention are directed towards a simulant and method relating to producing a simulant. For example, a simulant of a target threat includes at least one component ingredient characterized by a corresponding component loss factor that is essentially zero. The simulant is configured to exhibit a simulant dielectric constant corresponding to a simulant reflectivity substantially equivalent to a threat reflectivity. A method of producing a simulant of a target threat includes generating an ellipse-like curved solution space corresponding to a plurality of candidate threat reflectivities, identifying a threat dielectric constant, from among respective threat dielectric constants of the candidate threat reflectivities forming the curved solution space, and identifying at least one weight proportion of at least one corresponding simulant ingredient.

  • Publication number: 20190194086
    Abstract: Various embodiments of the present invention are directed towards a simulant and method relating to producing a simulant. For example, a simulant of a textured target threat includes a background material associated with a background attenuation, and a texture component(s) dispersed in the background material and associated with a component attenuation and a component characteristic. The component characteristic prevents the component attenuation of the texture component from being homogeneously dispersed throughout the background attenuation of the background material, to cause the simulant to mimic an aspect(s) of an X-ray signature of the textured target threat.
