Abstract: Diagnostic imaging of deep targets in the body requires sufficient signal amplitude to overcome effects such as attenuation with depth and thermal noise produced in signal reception. Coded excitation provides several strategies to increase the total transmitted energy without exceeding peak amplitude safety limits. Temporal coding has proven particularly effective, but these frequency or amplitude modulation techniques require additional transmit capabilities and often require complex processing to reduce decoding artifacts. An alternative code is presented based on time delays that relies on repeated transmit pulses that can be decoded using spatiotemporal synthetic aperture processing. A 16-pulse code is demonstrated that achieves an 11.1 dB improvement in signal-to-noise ratio (SNR) while maintaining axial resolution and sufficient range lobe performance.

Abstract: Dynamic windows with adjustable tint give users greater control over flow of light and heat. Reversible metal electrodeposition dynamic windows include (i) a transparent or translucent conductive electrode; (ii) an electrolyte solution in contact with the electrode, the electrolyte solution comprising metal cations that are reversibly electrodeposited onto the transparent electrode upon application of a cathodic potential; and (iii) a counter electrode. The electrolyte solution advantageously includes a small amount of an additive (e.g., an inhibitor, an accelerator, a leveler, or an organic or inorganic molecule that similarly serves to enhance the surface morphology of the metal cations during reversible metal electrodeposition onto the transparent electrode). Such enhancement of surface morphology during the reversible electrodeposition of the metal tinting layer over the electrode enhances one or more of color neutrality, transmittance characteristics of visible wavelengths (e.g.

Abstract: The present invention provides a method of PEGylating a human truncated cystathionine ?-synthase protein containing a mutation of a cysteine to a serine at amino acid position 15 (htCBS C15S). The htCBS C15S was PEGylated with one of 5 kDa, 10 kDa, or 20 kDa NHS ester PEG molecules. In-process monitoring of the PEGylation process was used in the method to reduce levels of unPEGylated htCBS C15S and htCBS C15S with insufficient PEGylation. Administration of the PEGylated htCBS C15S had efficacy throughout the course of treatment for homocystinuria.

Abstract: Through discrimination of the scattered signal polarization state, a lidar system measures a distance through semi-transparent media by the reception of single or multiple scattered signals from a scattering medium. Combined and overlapped single or multiple scattered light signals from the medium can be separated by exploiting varying polarization characteristics. This removes the traditional laser and detector pulse width limitations that determine the system's operational bandwidth, translating relative depth measurements into the conditions of two surface timing measurements and achieving sub-pulse width resolution.

The magnetographic camera may include a laser light source to illuminate the vapor cell causing a magnetic field image of a sample to be generated.

Abstract: A prodrug enzyme covalently photoconjugated to a live cell receptor survives endosomal proteolysis and retains its catalytic activity on the living cell membrane over multiple days. Antibody-directed enzyme prodrug therapy is a promising approach for selective treatment of solid tumors, but methods are needed to preserve enzyme activity on living cell membranes over multiple prodrug dosings. A fusion protein was designed with both an anti-epidermal growth factor receptor (EGFR) affibody and the prodrug enzyme cytosine deaminase, which can convert prodrug 5-fluorocytosine to the anticancer drug 5-fluorouracil. A benzophenone group was added at a site-specific mutation within the affibody portion, and the fusion protein was selectively and irreversibly photoconjugated to EGFR receptors expressed on membranes of live MDA-MB-468 breast cancer cells.

Abstract: A digital direct line-of-sight (DLOS) intermediate frequency (IF) signal of a DLOS component of an RF carrier signal transmitted by a transmitter located above the surface of the earth and a digital reflected IF signal of a reflected component of the carrier signal that is reflected from a specular point (SP) on the surface of the earth are received. Modeled reference signal parameters are generated using the digital DLOS IF signal and known locations of one or more receiving antennas, the transmitter, and the SP. A reference signal is generated based on the modeled reference signal parameters and feedback of a previously estimated ??. The reference signal is correlated with the digital reflected IF signal to produce in-phase (I) and quadrature-phase (Q) correlation results. An estimated C/N0 and an estimated ?? for the digital reflected IF signal are calculated from the correlation results.

Abstract: A system for sensing phase changes in a medium includes a bidirectional interferometer having a reference arm and a sensing arm, two inputs at each of the two ends of the interferometer, and a circulator disposed between each input and the interferometer.

The circulators pass the squeezed state pulses into the interferometer and route reflections of the pulses to the detectors. Classical pulses may provided at the other input at each end of the interferometer.
