Abstract: A system and a method for deterring unauthorized access to an account. The method includes the steps of receiving a user login request from one of a plurality of account holder computers, then identifying a username associated with the received user login request, a time associated with the received user login request, and an internet protocol (IP) address associated with the received user login request. The method and system determine a number of prior login requests received from the identified IP address during a duration of time TR prior to the identified time. Each of the received login requests has a unique username that is different than the identified username. The method includes the step of disabling access to the account associated with the identified username when the determined number of received login requests is above a request threshold B.

Abstract: Embodiments of the present invention are directed to fabrication method and resulting structures for placing self-aligned top vias at line ends of an interconnect structure. In a non-limiting embodiment of the invention, a line feature is formed in a metallization layer of an interconnect structure. The line feature can include a line hard mask. A trench is formed in the line feature to expose line ends of the line feature. The trench is filled with a host material and a growth inhibitor is formed over a first line end of the line feature. A via mask is formed over a second line end of the line feature. The via mask can be selectively grown on an exposed surface of the host material. Portions of the line feature that are not covered by the via mask are recessed to define a self-aligned top via at the second line end.

Abstract: The invention provides, in some aspects, methods of optimizing an app for execution on a client device by identifying components of the app used in such execution by a user having a designated role who accesses the app for download via a designated portal. A component can be, for example, a source code file or portion thereof, including, for example, a portion defining a widget or other user interface element. For each component, the method (i) identifies source code files on which execution of that component depends, e.g., in connection with execution of the particular app by the particular user, and (ii) generates a dependency-ordered stack of the source code files for that component. In further accord with those aspects of the invention, the method combines the dependency-ordered stacks into a single such stack and transfers the source code in an order specified by that stack to the client device for loading and execution.
