Techniques, systems, devices and materials are disclosed for implementing and fabricating drug delivery and imaging vehicles, which are activated in the body at a tissue of interest by focused ultrasound. In one aspect, a drug delivery vehicle can include a carrier having an outer membrane that envelopes an acoustic sensitizer particle and a payload substance to be delivered to the target tissue. The outer membrane can protect the acoustic sensitizer particle and the payload substance from degradation and opsonization. The outer membrane can be functionalized with a tumor targeting ligand to cause the drug delivery vehicle to selectively accumulate in a tumor region over other tissues, as well as with an agent to increase circulation time by reducing uptake from undesired body tissues, organs, and systems.

A parallel architecture matrix algebraic processing system exhibits patterns of arrayed (i) light transmitters and (ii) light receivers that are identical, but at differing scales. Planar arrays of one or more optoelectronic processors--principally semiconductor chips or chip arrays--having both computational and light input/output capabilities optically communicate from one plane to the next through free-space space-invariant optical data distributions--principally lenses and computer-generated holograms--having both replication and distribution capabilities. Each optoelectronic processor, or OP, consists of a number of arrayed optoelectronic processing elements, or OPEs. The OPEs, in turn, typically consist of a number of optoelectronic sub-processing units are preferably electrically interconnected in a tree-based structure, preferably an H-tree. Leaf units include typically one light detector plus local memory, logic circuitry, and electrical input/output. Fanning units typically include local memory, logic circuitry, and electrical input/output. A root unit typically includes electrically-connected local memory, logic circuitry, electrical input/output, and a light transmitter. Vector results of algebraic computations and combinations are flexibly performable in the units of each OPE, and variously optically distributable to other OPEs in successive OPs. The versatile algebraic vector manipulations and vector distributions support primitive functions such as intrinsic and extrinsic vector outer products; operations such as vector-matrix multiplication; and complex systems such as neural networks, fuzzy logic and relational databases. A system of .gtoreq.10.sup.3 fully optically communicating OPEs achieves capacities of 10.sup.6 -10.sup.8 interconnects, and processing speeds of 10.sup.12 interconnects/second.
摘要:
Apparatuses and systems for photon detection can include a first optical sensing structure structured to absorb light at a first optical wavelength; and a second optical sensing structure engaged with the first optical sensing structure to allow optical communication between the first and the second optical sensing structures. The second optical sensing structure can be structured to absorb light at a second optical wavelength longer than the first optical wavelength and to emit light at the first optical wavelength which is absorbed by the first optical sensing structure. Apparatuses and systems can include a bandgap grading region.
摘要:
A motionless parallel head reads an optical disk having an active surface encoded with an arrayed multiplicity of one-dimensional holograms. Each 1-D hologram is a computer-encoded representation of, typically, one 128 pixel slice of an image. A group, typically 128, 1-D holograms are positionally distributed, and positionally shifted or staggered one to the next, radially along the disk's active surface so as to fit a complete radius. Typically 14,000 groups are circumferentially-displaced around a 51/4" Compact Disk (CD), forming a herringbone pattern. During readout the encoded CD is simultaneously illuminated along the entirety of one of its radius lines within which a group of holographic data blocks are fitted. The illuminated group of holographic data blocks are optically transformed in parallel by one or more lenses, and preferably by a Hybrid refractive/diffractive Optical Lens (HOL), so as to two-dimensionally spatially encode the wavefront of the light beam by which the group of holographic data blocks was illuminated. The 2-D spatially-encoded light beam is detectable by an array of light detectors. When the disk is rotated then sucessive groups of holographic data blocks that are fitted along successive radius lines are successively retrieved, group by group, at a typically 1.1 Gbyte/sec rate. Such an optical memory is useable as the secondary storage of a high performance optoelectronic associative memory system.
