Exemplary embodiment can utilize the properties of tunable thin-film, material (e.g., graphene) to efficiently modulate the intensity, phase, and/or polarization of transmitted and/or reflected radiation, including mid-infrared ("mid-IR") radiation. Exemplary embodiments include planar antennas comprising tunable thin-film material sections and metallic sections disposed in contact with the tunable thin-film material sections, each metallic section having a gap with at least one dimension related to a wavelength of the radiation, which in some embodiments may be less than the wavelength. The metallic layer may comprise rods arrange in one or more shapes, or one or more apertures of one or more shapes. Embodiments of the antenna may also comprise a substrate, which may be a semiconductor or conductor in various embodiments. Embodiments also include systems, computer-implemented methods, devices, and computer-readable media for effectuating desired modulation of incident radiation by, e.g., varying the doping level of the tunable thin-film material.
摘要:
A low-cost, robust method for automatically tuning a coupled resonator to match a wavelength of electromagnetic radiation emitted from an applied laser source. Dithering signals are used for automatic wavelength tuning and thermal stabilization of microring resonators. The disclosed method can be applied using low-speed analog and digital circuitry, to create a complete photonic interconnection network. The methods disclosed also automatically detect, measure, and correct for resonance shift.

Sub- 100 micron multimodal nanoparticles have four main components: 1) a target element (peptides, lipids, antibodies, small molecules, etc.) that can selectively bind to cells, tissues, or organs of the body; 2) a diagnostic agent such as a fiuorophore or NMR contrast agent that allows visualization of nanoparticles at the site of delivery and/or a therapeutic or prophylactic agent; 3) an outside "stealth" layer that allows the particles to evade recognition by immune system components and increase particle circulation half-life; and 4) a biodegradable polymeric material, forming an inner core which can carry therapeutics and release the payloads at a sustained rate after systemic, intraperitoneal, or mucosal administration. These particles possess excellent stability, high loading efficiency, multiple agent encapsulation, targeting and imaging. They are targeted to sites of, or associated with, inflammation caused by a disease, disorder; trauma, chemotherapy or radiation.

The methods and compositions relate to altering the activation and/or activity of the bitter- sensing taste receptor cells and the PKD2L1 -expressing taste receptor cells. The invention also relates to food and food products containing agents and composition that alter the activation and/or activity of the bitter-sensing taste receptor cells and the PKD2L1- expressing taste receptor cells.
摘要:
In one aspect the present invention is directed to mutant NGAL proteins that have the ability to bind to siderophores, such as enterochelin, and to chelate and transport iron, and that are excreted in the urine. Such NGAL mutants, and complexes thereof with siderophores, can be used to clear excess iron from the body, for example in the treatment of iron overload. The NGAL mutants of the invention also have antibacterial activity and can be used in the treatment of bacterial infections, such as those of the urinary tract.
