Abstract:

A semiconductor-based structure includes a substrate layer, a compressively strained semiconductor layer adjacent to the substrate layer to provide a channel for a component, and a tensilely strained semiconductor layer disposed between the substrate layer and the compressively strained semiconductor layer. A method for making an electronic device includes providing, on a strain-inducing substrate, a first tensilely strained layer, forming a compressively strained layer on the first tensilely strained layer, and forming a second tensilely strained layer on the compressively strained layer. The first and second tensilely strained layers can be formed of silicon, and the compressively strained layer can be formed of silicon and germanium.

International Classification:

G02F 1/03

US Classification:

359241000

Abstract:

An electro-absorption light intensity modulator device is provided that comprises a first and a second layer disposed relative to the first layer so as to provide a light-absorbing optical confinement region. The first layer comprises a first insulator layer, and the light-absorbing optical confinement region comprises at least one quantum-confined structure. The at least one quantum-confined structure possesses dimensions such, that upon an application of an electric field in the at least one quantum-confined structure, light absorption is at least partially due to a transition of at least one carrier between a valence state and a conduction state of the at least one quantum-confined structure. A method is also provided for fabricating an electro-absorption light intensity modulator device. The method comprises providing a first insulator layer, disposing a light absorption region over the first insulator layer, and disposing a second insulator layer over the light absorption region, wherein light absorption region comprises at least one quantum-confined structure. The at least one quantum-confined structure possesses dimensions such that, upon an application of an electric field in the at least one quantum-confined structure, light absorption is at least partially due to a transition of at least one carrier between a valence state and a conduction state of the at least one quantum-confined structure.

International Classification:

G06F 7/544

US Classification:

708490

Abstract:

Methods, apparatuses, and computer program products for squaring an operand include identifying a fixed-point value with a fixed word size and a substring size for substrings of the fixed-point value, wherein the fixed-point value comprises a binary bit string. A square of the fixed-point value can be determined using the fixed point value, the substring size, and least significant bits of the fix-point value equal to the substring size.

Abstract:

Embodiments of the invention provide for Web site reachability management in content browsing. A method of the invention includes monitoring different requests for different resources at respectively different resource location addresses initiating from different content browsers of different end users. Different responses to ones of the different requests that include an error code indicating an inability to provide a requested one of the different resources are detected and ones of the resource location addresses associated with corresponding ones of the different responses that include the error code are stored in a list. Finally, the each of resource location addresses are polled to determine whether or not a corresponding one of the resources is able to be retrieved. In response to determining that a resource of a resource location address in the list has become retrievable, the address is removed from the list and an associated end user notified.

Abstract:

Evaluating node fulfillment capacity in node order assignment by receiving a current order for node order assignment, retrieving data of each node, the retrieved data of each node including current capacity utilization, determining a probability of backlog on an expected ship date of each node, the probability of backlog being based on the retrieved current capacity utilization, determining a capacity utilization cost of each node based on the probability of backlog on the expected ship date, automatically calculating a fulfillment cost of each node of the current order based on the capacity utilization cost, identifying one or more nodes for the current order with the lowest fulfillment cost and automatically generating a node order assignment assigning the current order to one of the one or more nodes with the lowest fulfillment cost.

Abstract:

Data content delivery and validation in a computer environment may provide a file system in the computer environment, the file system subdivided into unique folder locations per content type, each of the unique folder locations representing a content type folder. The file system is monitored for changes to a content type folder. An occurrence of a manifest file in the content type folder may be detected, the occurrence of the manifest file ensuring that all files in a package of files associated with the manifest file have arrived. Content of the manifest file may be analyzed to check validity of the files. A content package registry may be queried to determine a base job for processing a given content type associated with the package of files, and the base job may be run to process the package of files.

Abstract:

Embodiments provide an access point (AP) that includes a set of one or more base-station functions configured to connect a user equipment (UE) to the AP over a wireless communication interface; and a set of one or more core-network functions configured to provide services to the UE. The AP allocates an Internet Protocol (IP) address to the UE by using at least one Dynamic Host Configuration Protocol (DHCP) server that is external to the AP.
