摘要:
A diffusion barrier film includes a layer of compositionally graded titanium nitride, having a nitrogen-rich portion and a nitrogen-poor portion. The nitrogen-rich portion has a composition of at least about 40% (atomic) N, and resides closer to the dielectric than the nitrogen-poor portion. The nitrogen-poor portion has a composition of less than about 30% (atomic) N (e.g., between about 5-30% N) and resides in contact with the metal, e.g., copper. The diffusion barrier film can also include a layer of titanium residing between the layer of dielectric and the layer of compositionally graded titanium nitride. The layer of titanium is often partially or completely converted to titanium oxide upon contact with a dielectric layer. The barrier film having a compositionally graded titanium nitride layer provides excellent diffusion barrier properties, exhibits good adhesion to copper, and reduces uncontrolled diffusion of titanium into interconnects.

Method of preparing a biological sample appropriate for use in a subsequent in vitro nucleic acid amplification reaction. The method involves a rapid, transient exposure to alkaline conditions which can be achieved by mixing an alkaline solution with a pH-buffered solution that includes a detergent and the biological sample to be tested for the presence of particular nucleic acid species using in vitro amplification. The invented method advantageously can improve detection of some target nucleic acids without substantially compromising detectability of others. The method is particularly useful for simultaneously preparing RNA and DNA templates that can be used in multiplex amplification reactions.

The present invention provides for a polymer composite film with a treated filler and methods for making the same. The polymer composite film includes a polymer capable of being formed into a polymeric film and a treated filler which is dispersed throughout the polymer forming the composite film. The filler is treated by techniques which exfoliate, delaminate or intercalate the filler particles into individual micro and/or nano size particulates and platelets. Ideally, the treated filler has a medium particle size ranging from about 0.1 nm-10 mm. The treated filler enhances the rigidity, barrier properties, heat deflection temperature, clarity, nucleation characteristics and fire retardant characteristics of the film. The products fabricated from the polymer composite film include sleeves, protective packaging, films, bags, liners, house-wraps, overwrap films, bubble cushion, packaging for food products, boil-in bags, heat shrinkable films, heat shrinkable bags, pouches, and thermoformed packages. The present invention also provides for methods of fabricating the polymer composite film.
摘要:
An oxygen scavenging packet containing an iron-based oxygen scavenger and an electrolyte is set forth in which the rate of uptake of oxygen is increased by virtue of the introduction into the packet of an oxygen uptake accelerator containing water. Methods of increasing the rate of oxygen absorption by use of the iron-based oxygen scavenging packet are also set forth.

A computer implemented method for processing lottery sales data comprises the steps of: enabling a user of a computer to query data representing lottery ticket sales for a plurality of lottery retailers based on at least one criterion from a predetermined list of criteria; and causing display of a table on a computer, the table containing a listing of a subset of lottery retailers from the plurality of lottery retailers that meet the at least one criterion, the table further containing data representing lottery ticket sales associated with the subset of retailers.
摘要:
A method and system for motion estimation modeling for cardiac and respiratory motion compensation is disclosed. Specifically, a coronary sinus catheter is tracked in a plurality of frames of a fluoroscopic image sequence; and cardiac and respiratory motion of a left atrium is estimated in each of the plurality of frames based on tracking results of the coronary sinus catheter using a trained motion estimation model.

Embodiments of a battery charger and methods for operating same are disclosed. The charger has a plurality of charging pins, and a device to be charged may be plugged into the charger in multiple orientations. The charger detects the device's orientation and sets the states of its charging pins appropriately to charge the device. Optionally, the charger may have additional pins, likewise settable according to a device's orientation, for supplying power and/or communications to the device during charging.
