摘要:
Integrated circuit packages that may be easily stacked one on top of the other are disclosed. The package includes a molded plastic body having metal-coated interconnection posts on both its upper and lower surfaces. An integrated circuit is mounted on the upper surface. Metal traces on the upper surface electrically connect each bonding pad on the integrated circuit to a one of a plurality of groups of four interconnection posts on the upper surface. Vias through the substrate electrically connect each group of four posts on the upper surface to an interconnection post on the lower surface of the package. Two or more packages can be stacked and electrically connected by wedging the lower posts of a top package between each group of four posts on the upper surface of a lower package. The lower posts of the lower package may be soldered to a conventional printed circuit board, or may be mounted on a mounting substrate that also has corresponding groups of four interconnection posts.

An intravascular catheter that exhibits the combined features of superior flexibility, softness, radiopacity and oval/kink resistance. The catheter includes an elongate shaft having a proximal region, a distal region and a lumen extending therethrough. The proximal region of the shaft includes an inner lubricious polymer layer, a reinforcement layer and an outer layer. The reinforcement layer comprises a braid having one or more metallic members and a plurality of polymer members wherein each polymer member comprises a plurality of monofilaments, preferably formed of LCP. The polymer members of the braid provide improved flexibility and softness in addition to high burst pressure. The metallic member(s) of the braid provide improved radiopacity and oval/kink resistance. The catheter may also include a longitudinal member extending along the reinforcement layer.

The present invention provides a method of using a getter layer on a semiconductor substrate having a first metal stack formed thereon to improve metal to metal contact resistance. The method comprises the steps of forming a getter layer, which may be titanium, on the first metal stack, wherein the getter layer has a higher affinity for oxygen or a higher getter capability than the first metal stack, substantially removing the getter layer by exposing the getter layer to radiation, and forming a second metal stack, which in an advantageous embodiment may also be titanium, on the first metal stack.

Polymer insulators and methods of using polymer insulators are disclosed. In some embodiments, a method includes separating a first portion of a subject's tissue from a second portion of the subject's tissue so that there is a space between the first and second portions of tissue. Deionized water, a buffered saline solution, liquid polymers, gels, particles, foams, and/or gases are disposed between the first and second portions of tissue, and the first portion of tissue is exposed to energy to treat the first portion of tissue.

A modular, on-site, wastewater treatment system removes total nitrogen, phosphorus, BOD, and TSS. A flow equalization module provides a constant flow rate to the system eliminating the adverse effects from variations in flow rate throughout the day. Treatment modules are similarly sized to provide a compact, modular system. The nitrification module is a fixed-film, flooded packed bioreactor to facilitate bioconversion of ammonia to nitrate. Aeration of the module provides the oxygen needed for the bioconversion as well prevents clogging of the film. Solids from the nitrification process are removed in a first cone-shaped settling tank. De-nitrification where nitrate is converted to nitrogen gas takes place in an anaerobic fixed-film bioreactor. Carbon-based bio-film carriers provide a carbon source for de-nitrification. A final cone-shaped settling tank separates solids from the treated wastewater. Additional modules to address removal of phosphorous or other contaminants can be added to the modular system.
摘要:
A tissue ablation assembly comprises an elongate probe device, at least one ablation electrode element carried by the probe device for conveying ablation energy, and at least one magnetic element for substantially altering the path of the ablation energy conveyed by the electrode element(s). In one embodiment, the magnetic element substantially urges the ablation energy radially outward. In another embodiment, magnetic element takes the form of a ring magnet that exhibits at least four alternating magnetic poles circumferentially disposed around the probe device axis. A method of treating tissue (e.g., a tumor) is also provided. The method comprises introducing a probe device into the patient, conveying ablation energy from the probe device, and applying a magnetic field adjacent the probe device to substantially alter the path of the ablation energy, e.g., by urging the ablation energy conveyed from the probe device radially outward into the tissue to create a tissue lesion, or by urging the ablation energy longitudinally.

The invention provides methods of diagnosing and treating cancer in a subject. The inventors have identified a series of dysregulated miRNAs that are indicative of triple-negative breast cancer. In some embodiments, the invention further provides for the administration of a cancer therapy to the subject.
摘要:
Methods for the treatment of xerostomia are described, hi particular, the present invention takes advantage of the inventors' observation that xerostomia is caused by induction of apoptosis, and can be inhibited by interfering with the cellular processes that trigger apoptosis in cells receiving chemo- and/or radiotherapy.
