Abstract: A system and method of detecting a source of a rumor in a social media network is disclosed. The social media network includes a plurality of node clusters, each of the plurality of nodes therein having at least one edge connection to a corresponding number of different nodes in the same cluster. The system identifies a plurality of gateway nodes, each having at least one weak tie connection with a corresponding gateway node from a different node cluster; selects a subset of gateway nodes as sensors to measure arrival times of a rumor; and selects a candidate node cluster based on these arrival times. From there, the system selects a set of nodes in the candidate cluster to measure arrival times of a rumor from a source node, and selects a candidate node from the candidate cluster as having a high probability of being the source node.

Abstract: A protocol, server and client producing high performance web service with security and lower power requirements. A web protocol retrofits web browsers with a translating program on the client to relay the messages to the server with less bandwidth. Optionally, the protocol is embedded within a custom browser to communicate directly, eliminating translation and layers of programming. By storing web pages in a binary format and skipping the intermediate representation of HTML, CSS, and JavaScript the size of the web page, and the time it takes to display it can be reduced. The elimination of JavaScript also increases security because JavaScript is a known, common source of attacks. Communication of static data is minimized. A key repository and automated client use thereof may eliminate manual entry and transmission of access credentials making phishing attacks impossible.

Abstract: Graphene-carbon nanotube multi-stack three-dimensional architectures (graphene-CNT stacks) are formed by a “popcorn-like” growth method, in which carbon nanotubes are grown throughout the architecture in a continuous step. Alternating layers of graphene and a transition metal are grown by a vapor deposition process. The metal is fragmented and etched to form an array of catalytic sites. Carbon nanotubes grow from the catalytic sites in a vapor-solid-liquid process. The graphene-CNT stacks have applications in electrical energy storage devices, such as supercapacitors and batteries. The directly grown carbon nanotube array between graphene layers provides ease of ion diffusion and electron transfer, in addition to being an active material, spacer and electron pathway.

Lines extending between symbols graphically indicate the relatedness of the data that the symbols represent and the size of symbols may indicate the calculated relevance to user interests.

Abstract: The present disclosure relates to fabricating sacrificial microfiber templates from any biocompatible and resorbable materials depending on the time needed for dissolving the microfiber template to free the endothelial tube with open lumen. Microfiber networks with distinct patterns and defined diameters initially serve as a template to support the growth of vascular cells (endothelial cells or their progenitor cells, or combined with mural cells such as pericytes) and then dissolve to form an empty endothelium lumen. The incorporation of sacrificial microfiber networks encapsulated with vascular cells into 3D cell-rich constructs allows for the creation of various vascularized tissues.

Abstract: A method of high-throughput printing and selective transfer of graphene onto a substrate includes the steps of: providing a thermal release tape having graphene adhered thereto; placing a substrate onto the graphene; pressing the thermal tape and the graphene against the substrate at a uniformly-distributed pressure; heating localized portions of the thermal tape and graphene using a localized heat source, thereby diminishing the adhesive properties of the thermal release tape in the localized portions and transferring graphene from said localized portions to the substrate; and separating the thermal release tape from the substrate. The method may include the further step of moving the localized heat source to selected positions on the thermal release tape during the heating step, thereby forming a pattern of heated portions. The method may use a laser beam as the localized heat source, movement of the laser beam being performed by a computer-controlled deflectable mirror.

Abstract: In permeability lung edema, cardiogenic lung edema or neonatal respiratory distress, there is heterogeneous liquid distribution throughout the lungs. The excess alveolar liquid reduces gas exchange. Mechanical ventilation is used to improve gas exchange. In the presence of heterogeneous liquid distribution, there are surface tension-dependent stress concentrations in septa separating aerated from flooded alveoli. Mechanical ventilation, by inflating the lung above normal volumes, thus increasing surface tension above normal, exacerbates the stress concentrations and consequently injures, or exacerbates pre-existing injury of, the alveolar-capillary barrier. Any means of lowering surface tension should lessen ventilation injury of the lung. In the present invention, dilute exogenous surfactant solution or surfactant protein C solution interacts with albumin to lower surface tension, likely through effective promotion of surfactant lipid adsorption.
