摘要:
Systems, including compositions, kits, and methods, particularly for photoluminescence applications. The systems may include, among others, (1) organic chelators, (2) complexes between the chelators and lanthanide ions, and (3) precursors, derivatives, and uses thereof. The chelators may include a 1,4,7,10-tetraazacyclododecane ring system, for example, having the formula: Here, R1, R2, and R3 are substituents of the tetraazacyclododecane ring system, that is further substituted at the 10-position by a sensitizer Z that is typically a polyheterocyclic ring system. The organic chelator may be capable of forming a luminescent complex with a lanthanide ion, and is optionally further substituted by a reactive functional group or a conjugated substance. The resulting lanthanide complex may be useful in luminescence-based assays, such as energy transfer assays, among others.

摘要:
A fuel/air mixing apparatus, such as a main swirler assembly (400) comprising a sleeve (410), provides for additional air entry around the perimeter of a bore (440) through which passes a fuel/air mixture. The additional air reduces or eliminates flashback during operation of a gas turbine comprising the assembly (400). In some embodiments, a plurality of gaps (464) exists between spaced apart tabs (462) along a downstream end (460) of the sleeve (410). During gas turbine operation, air flows through both a flashback annulus (411) and the gaps (464). In other embodiments, a plurality of holes are placed upstream and in line with the tabs (1004) to supplement the air flow through gaps (1006). In yet other embodiments, rows (1102) of holes (1104) are provided to supplement the airflow. Downstream ends (460,1218) may interface with a downstream-oriented lip (460) or with an upstream-oriented lip (1224). The interfacing may comprise a fit effective to damp vibration and to increase the natural frequency.
摘要:
A method, system and program product for replacing isotropic hole shapes in a wiring layout with non-equiaxial hole shapes that are arranged in a direction of current flow, which increases current flow along the wire's longitudinal axis while decreasing current flow along the wire's transverse axis. One aspect of the invention includes a method including determining a direction of electrical current flow in a portion of a wiring layout; and placing at least one non-equiaxial hole shape within the portion of the wiring layout, wherein the non-equiaxial hole shape is arranged in the direction of electrical current flow. The invention accommodates the limitations of copper CMP within an automated tool without sacrificing the efficiency of a hand-tuned layout. The invention also includes a semiconductor device including at least one non-equiaxial hole shape.
摘要:
A set of furnace spacers for spacing a first preform from a second preform, the first and second preforms each having an outer periphery, a width, an inner opening having a periphery and a width, a first side defined by the outer periphery and said inner opening, the first side having a surface area, and a second side spaced from the first side. Each spacer in the set of spacers has a body having a first side having a surface area, and the sum of the first side surface areas of the spacers in a set is greater than about thirty percent of the preform first side surface area.
摘要:
A portable light intended for mounting on a garment as support includes two LED light sources spaced apart towards the rear of the portable light. A clipped base below on anchor facilitates locating a garment between the anchor and the base, and a spring action urges the base toward the anchor. A hingedly movable head for the LEDs is mounted on the housing to move to and form the housing. An opening of the housing causes a switch in the housing to move between an opened and closed position such that a circuit actives or de activates the LED lights when the head opens or closes relative to the housing.
摘要:
A pipelined packet processor is described having at least one pipeline, the at least one pipeline having one or more processing slots. Packets are assigned to available ones of the slots, and each of one or more of the assigned packets are processed during one or more cycles of processing. Upon or after a packet has undergone one or more cycles of processing, a packet classification or filtering decision is derived for the packet.
摘要:
A command instruction set for a packet data modification processor has a format in which a packet address, if present, specifies an encapsulated layer within the packet and a location within this encapsulated layer. The at least one command within the command instruction set specifies deriving at least a portion of a first packet from data taken from a second packet or the command.
