Methods and apparatus for selectively applying electrical energy to a target location within a patient's body, particularly including tissue in the spine. In a method of the invention high frequency (RF) electrical energy is applied to one or more active electrodes on an electrosurgical probe in the presence of an electrically conductive fluid to remove, contract or otherwise modify the structure of tissue targeted for treatment. In one aspect, a dura mater and spinal cord are insulated from the electrical energy by an insulator positioned on a non-active side of the probe. In another aspect, a plasma is aggressively formed in the electrically conductive fluid by delivering a conductive fluid to a distal end portion of the probe and aspirating the fluid from a location proximal of the return electrode. In another aspect, a distal end of an electrosurgical probe having at least one electrode on a biased, curved, bent, or steerable shaft is guided or steered to a target site within an intervertebral disc having a disc defect for treatment of tissue to be treated at the target site by the selective application of electrical energy thereto.

The present invention provides a compact coaxial nozzle useful in laser welding operations where the welding piece has a restricted or confined geometry. The nozzle is generally conical in shape, terminating in a relatively small tip. The nozzle includes a central laser discharge opening. The conical shape allows movement of the nozzle in confined areas. The nozzle includes a cooling jacket for proving coolant to the nozzle. The nozzle also includes a powder mixing chamber that provides good mixing of powdered filler material with a coaxial discharge around the laser. Finally, the nozzle further provides for inert gas to pass from an upper inlet, through passageways, out of a ring discharge. The ring discharge is also coaxially disposed around the central laser. Further the ring discharge provides mixing of the inert gas in order to minimize turbulent flow problems associated with restrictor plates.

Provided are methods for sequencing a nucleic acid that include fixing a template to a surface through a template localizing moiety and sequencing the nucleic acid with a sequencing enzyme, e.g. a polymerase or exonuclease. The sequencing enzyme can optionally be exchanged with a second sequencing enzyme, which continues the sequencing of the nucleic acid. The template localizing moiety can optionally anneal with the nucleic acid and / or associate with the sequencing enzyme. Also provided are compositions comprising a nucleic acid fixed to a surface via a template localizing moiety, and a first sequencing enzyme, which can sequence the nucleic acid and optionally exchange with a second sequencing enzyme present in the composition. Compositions in which a template localizing moiety is immobilized on a surface are provided. Compositions for sequencing reactions are provided. Also provided are sequencing systems comprising reaction regions in which or near which template localizing moieties are immobilized.

A large-capacity magnetic storage apparatus is disclosed, capable of performing ultra-high density magnetic recording of 50 gigabits or more per 1 square inch. In a perpendicular magnetic recording medium having a non-magnetic intermediate layer and a magnetic recording layer sequentially formed, the non-magnetic intermediate layer is composed of a layer having a face-centered cubic structure and containing a non-magnetic elements excluding Pt. Specifically, the intermediate layer mainly contains at least one selected from the group of elements constituted of Al, Cu, Rh, Pd, Ag, Ir and Au, and is composed of a film having a face-centered cubic (f. c. c.) structure. The magnetic recording layer contains at least Co, Cr and Pt, and is composed of a film having a hexagonal close-packed (h. c. p.) structure. More preferably, a non-magnetic h. c. p. intermediate layer is provided between the non-magnetic intermediate layer and the magnetic recording layer.

An object of the present invention is to provide flexibility in modifying or updating a communication system and the like of a vehicle-mounted network, thus reducing processing loads on electrical components modules and the like. In the present invention, a connector device with communication-controlling capability takes charge of controlling a communication system of a vehicle-mounted network, so that an electrical components module is specialized for its inherent processing other than the communication system. A control program about the communication system is rewritably stored in a rewritable non-volatile storage device in the connector device with communication-controlling capability, and the communication system is modified or updated only by renewing the control program stored in the non-volatile storage device in the connector device with communication-controlling capability.

Ultrasound for use in chemical reactions is generated by an electromagnet formed from an ultrasound transducer whose central feature is a loop of magnetostrictive material wound with coils oriented to produce an oscillating magnetostrictive force when an oscillating voltage is applied. The oscillations in the transducer loop are transmitted to an ultrasonic horn that is immersed in a reaction medium where the ultrasonic vibrations are transmitted directly to the reaction mixture.
