Compositions and methods are provided for preparing a metal substrate having a uniform textured surface with a plurality of indentations with a diameter in the nanometer and micrometer range. The textured surface is produced by exposing the substrate to an etching fluid comprising a hydrohalic acid and a mixture of a hydrohalic acid and an oxyacid, a chloride containing compound, and an oxidant. The etching solution can be used at ambient temperature. This textured surface enhances adherence of coatings or cells onto the textured surface, improves the retention of proteins on the surface, and encourages bone in-growth.

A pulsed laser comprises an oscillator and amplifier. An attenuator and / or pre-compressor may be disposed between the oscillator and amplifier to improve performance and possibly the quality of pulses output from the laser. Such pre-compression may be implemented with spectral filters and / or dispersive elements between the oscillator and amplifier. The pulsed laser may have a modular design comprising modular devices that may have Telcordia-graded quality and reliability. Fiber pigtails extending from the device modules can be spliced together to form laser system. In one embodiment, a laser system operating at approximately 1050 nm comprises an oscillator having a spectral bandwidth of approximately 19 nm. This oscillator signal can be manipulated to generate a pulse having a width below approximately 90 fs.

A system and method for imaging of a sample, e.g., biological sample, are provided. In particular, at least one source electro-magnetic radiation forwarded to the sample and a reference may be generated. A plurality of detectors may be used, at least one of the detectors capable of detecting a signal associated with a combination of at least one first electro-magnetic radiation received from the sample and at least one second electro-magnetic radiation received from the reference. At least one particular detector may have a particular electrical integration time, and can receive at least a portion of the signal for a time duration which has a first portion with a first power level greater than a predetermined threshold and a second portion immediately preceding or following the first portion. The second portion may have a second power level that is less than the predetermined threshold, and extends for a time period which may be, e.g., approximately more than 10% of the particular electrical integration time.

Selective occlusion of a blood vessel is achieved by selectively damaging endothelial cells at a target location in the blood vessel, resulting in the formation of a fibrin clot proximate to the damaged endothelial cells. Additional fibrinogen can then be introduced into the blood vessel if occlusion is not achieved, as the fibrinogen is converted to fibrin by enzymes released by the exposed thrombogenic tissue and activated platelets. Endothelial cells are selectively damaged using thermal effects induced by ultrasound, by mechanical effects induced by ultrasound, or by mechanical effects produced by a tool introduced into the blood vessel (such as a catheter-based tool). A particularly preferred technique for selectively damaging endothelial cells involves introducing an ultrasound activatable agent into the blood vessel, and causing cavitation in that agent using pulses of high-intensity focused ultrasound having a duration insufficient to induce thermal damage in adjacent perivascular tissue.

A portable X-ray unit, of a relatively light-weight, occoping a volume of less then one-half a cubic foot containing an x-ray head assembly, a unique Marx generator, a plurality of spark-gap switches and control electronics is disclosed. The Marx generator allows for the development of a relatively high voltage in excess of 100 kV, yet allows for the discharge thereof within the nanosecond range. The Marx generator is enclosed by an acrylic insulator that cooperates with an aluminum enclosure, which functions as a return current path for the capacitors in the Marx generator and also as a shield against the escape of electromagnetic radiation from the pulsed x-ray unit. The Marx generator and spark-gap switches are confined within the pressurized chamber that may contain nitrogen gas to reduce the separation of the gap in the spark-gap switches.

To store an input string of M N-tuples of bits, a substitution transformation is selected in accordance with the input string and is applied to the input string to provide a transformed string of M N-tuples of bits. M or more memory cells are programmed to represent the transformed string and preferably also to represent a key of the transformation. Alternatively, the memory selectively programs each of M or more cells to a respective one of 2N states. A mapping that maps the binary numbers in [0,2N−1] into respective states is selected in accordance with the input string and is used to program M cells to represent the input string. Preferably, a key of the mapping is stored in the memory in association with the M cells.

For transmitting data between a base station and a transponder, information packets modulated onto an electromagnetic carrier wave each include a header section, a middle section, and an end section. The data are encoded in the middle section using information symbols, e.g. representing digital "1s" and "0s". The header section of at least the first packet defines the number and unique identifications of all of the symbols that will be used for encoding the data in the middle section of this and / or subsequent packets. This transmission protocol defined in the header section can be varied in subsequent packets to adaptively adjust the transmission rate depending on the existing communication conditions and requirements such as high frequency regulations prescribed by national law. The transmission rate can be considerably increased, in comparison to a transmission rate that would otherwise be necessary for achieving a reliable transmission even under unfavorable conditions.

A method for delivering an isolated polynucleotide to the interior of a cell in a vertebrate, comprising the interstitial introduction of an isolated polynucleotide into a tissue of the vertebrate where the polynucleotide is taken up by the cells of the tissue and exerts a therapeutic effect on the vertebrate. The method can be used to deliver a therapeutic polypeptide to the cells of the vertebrate, to provide an immune response upon in vivo translation of the polynucleotide, to deliver antisense polynucleotides, to deliver receptors to the cells of the vertebrate, or to provide transitory gene therapy.
