The system, method, and computer program product are disclosed that track the evolution of a network over time through the analysis of media corpora associated with nodes of the network at each time slice. The media corpora may be analyzed to generate word clusters for each time slice that are then compared across time slices to determine how the network has evolved. The evolution may be tracked by determining the similarity of each word cluster of a particular time slice to each word cluster of another time slice. The similarity may be measured by a similarity score for each comparison that may be combined to determine an overall similarity of the network between the two time slices.

Tracking the evolution of topic rankings from contextual data

Electromechanical substance delivery devices are provided which implement low-power electromechanical release mechanisms for controlled delivery of substances such as drugs and medication. For example, an electromechanical device includes a substrate having a cavity formed in a surface of the substrate, a membrane disposed on the surface of the substrate covering an opening of the cavity, and a seal disposed between the membrane and the surface of the substrate. The seal surrounds the opening of the cavity, and the seal and membrane are configured to enclose the cavity and retain a substance within the cavity. An electrode structure is configured to locally heat a portion of the membrane in response to a control voltage applied to the electrode structure, and create a stress that causes a rupture in the locally heated portion of the membrane to release the substance from within the cavity.

Methods and systems for determining a time dependent relevancy score of an agent node among an evolving heterogeneous network are described. A processor may expand the heterogeneous network by generating temporal heterogeneous networks representing states of the heterogeneous network at different times. The processor may extract a set of agent nodes from each temporal heterogeneous network and may generate a relationship network based on the extracted agent nodes for each temporal heterogeneous network. The processor may remove the agent node from the temporal heterogeneous network to generate a conditional relationship network excluding the removed agent node. The processor may determine a relevancy score for the agent node based on the corresponding relationship network and the conditional relationship network. Each relevancy score for the agent node may correspond to a temporal heterogeneous network and may indicate an impact of removing the agent node from the corresponding temporal heterogeneous network.

Node relevance determination in an evolving network

A method provides a structure that includes a substrate having a metal layer disposed on a surface and a metal feature disposed on the metal layer. The method further includes immersing the structure in a plating bath contained in an electroplating cell, the plating bath containing a selected solder material; applying a voltage potential to the structure, where the structure functions as a working electrode in combination with a reference electrode and a counter electrode that are also immersed in the plating bath; and maintaining the voltage potential at a predetermined value to deposit the selected solder material selectively only on the metal feature and not on the metal layer. An apparatus configured to practice the method is also disclosed.

Selective solder plating

A method of manufacturing integrated devices, and a stacked integrated device are disclosed. In an embodiment, the method comprises providing a substrate; mounting at least a first electronic component on the substrate; positioning a handle wafer above the first electronic component; attaching the first electronic component to the substrate via electrical connectors between the first electronic component and the substrate; and while attaching the first electronic component to the substrate, using the handle wafer to apply pressure, toward the substrate, to the first electronic component, to manage planarity of the first electronic component during the attaching. In an embodiment, a joining process is used to attach the first electronic component to the substrate via the electrical connectors. For example, thermal compression bonding may be used to attach the first electronic component to the substrate via the electrical connectors.

Wafer stacking for integrated circuit manufacturing

A method of forming a flexible microbattery and battery is provided. The method including: forming a film with a cavity therein; applying a first outer flexible substrate to a first side of the film; applying a second outer flexible substrate to a second opposite side of the film, wherein a cathode, an anode, a separator and an electrolyte are located within the cavity and the film provides a first seal about the cathode, the anode, the separator and the electrolyte and wherein the first seal extends between the first outer flexible substrate and the second outer flexible substrate; cutting a trench through the first outer flexible substrate, the film and the second outer flexible substrate after the first seal is formed; disposing a curable material in the trench; curing the curable material to provide a second seal, wherein the first seal is located between the cavity and the second seal.
