A nanometer size roughened structure is formed on a surface of a light-emitting element, and luminous efficiency is improved. The roughened structure on the surface of the light-emitting element of the invention is formed into the following shape such that the refractive index smoothly changes: (1) the mean diameter of projections on the roughened surface is smaller than the light wavelength; (2) a pitch of the roughened surface is irregular; and (3) positions of the top and bottom of the roughened surface are distributed from their mean values within the light wavelength in order to give a smooth gradient of the refractive index. The surface of such light-emitting element is obtained by forming a thin film on the surface of the light-emitting element using a resin composition which contains a block copolymer or graft copolymer and forms a micophase-separated structure in a self-organization manner; selectively removing at least one phase of the microphase-separated structure of the thin film formed on the surface; and etching the surface of the light-emitting element using the remaining phase as an etching mask.

Method and apparatus for the self-organization of nodes into groups in network computing environments. Embodiments may provide the ability to deploy nodes on a network, and to allow the nodes to organize into groups without human intervention. In one embodiment, a node may broadcast a query looking for a master node for the group. If the query produces no responses, the node may self-elect as the master node for the group and the node may broadcast its presence as the master node. If two or more nodes self-elect as master nodes, the nodes may negotiate to determine which node will be the master node. If the master node becomes unavailable, the remaining nodes in the group may elect a new master node. Some embodiments may be implemented on a peer-to-peer platform, such as the JXTA peer-to-peer platform, which may allow the scope of the group to span subnetworks and networks.

A data analysis system with dynamic information extraction and self-organizing evidence construction finds numerous applications in information gathering and analysis, including the extraction of targeted information from voluminous textual resources. One disclosed method involves matching text with a concept map to identify evidence relations, and organizing the evidence relations into one or more evidence structures that represent the ways in which the concept map is instantiated in the evidence relations. The text may be contained in one or more documents in electronic form, and the documents may be indexed on a paragraph level of granularity. The evidence relations may self-organize into the evidence structures, with feedback provided to the user to guide the identification of evidence relations and their self-organization into evidence structures. A method of extracting information from one or more documents in electronic form includes the steps of clustering the document into clustered text; identifying patterns in the clustered text; and matching the patterns with the concept map to identify evidence relations such that the evidence relations self-organize into evidence structures that represent the ways in which the concept map is instantiated in the evidence relations.

An ad hoc network organizes itself to provide communications without need for an a priori designated central control mechanism or base stations. Such self-organization is challenging in a multihop ad hoc network having member nodes that are highly mobile and widely distributed. A Synchronous Collision Resolution (SCR) protocol and a Node State Routing (NSR) protocol are well suited to provide efficient ad hoc network organization. SCR is an access protocol that achieves high capacity collision free access using a signaling approach that creates a random cellular-like network after each signaling period. NSR is a routing protocol that uses the dissemination of node states to predict link availability and to assign metrics to those links for the creation of optimized routes. In use, the present invention provides quality of service and supports energy conservation for the mobile nodes.

As other pairs of units activate, they can self-organize their transmissions by joining an existing network or by creating new networks.

A cluster tree network formed by self-organization of a number of nodes. The method of self-organization includes processes for cluster formation, cluster network maintenance, intra-cluster communication. In the cluster formation process, each node discovers if any neighboring node is a cluster head or if any node is already a member of a cluster (thus making it a networked node), and if a cluster head or a networked node is discovered, each node establishes a communication link with the cluster head or the networked node. If no cluster head or networked node is discovered, the node itself becomes a cluster head. The network is maintained by each node periodically broadcasting a HELLO message to neighboring nodes, receiving responses to the HELLO message and updating a neighbor list in accordance with responses to the HELLO message. Multi-cluster networks are also provided using the processes of inter-cluster network formation, inter-cluster network maintenance, and inter-cluster communication. The resulting network has one or more clusters of nodes, each with a cluster head and a number of member nodes, each assigned a node identifier by the cluster head. In a multi-cluster network, a designated device assigns identifies to each cluster head in the network. Border nodes, which are members of at least two clusters, act as routers connecting the clusters and relaying information packets between the clusters.

A mask having features formed by self-organizing material, such as diblock copolymers, is formed on a partially fabricated integrated circuit. Initially, a copolymer template, or seed layer, is formed on the surface of the partially fabricated integrated circuit. To form the seed layer, diblock copolymers, composed of two immiscible blocks, are deposited in the space between copolymer alignment guides. The copolymers are made to self-organize, with the guides guiding the self-organization and with each block aggregating with other blocks of the same type, thereby forming the seed layer. Next, additional, supplemental diblock copolymers are deposited over the seed layer. The copolymers in the seed layer guide self-organization of the supplemental copolymers, thereby vertically extending the pattern formed by the copolymers in the seed layer. Block species are subsequently selectively removed to form a pattern of voids defined by the remaining block species, which form a mask that can be used to pattern an underlying substrate. The supplemental copolymers augment the height of the copolymers in the seed layer, thereby facilitating the use of the copolymers for patterning the underlying substrate.
