The MPEG-2 Transport Stream (TS) has been widely accepted not only for providing digital TV services, but also as a subnetwork technology for building IP networks. This document describes a Unidirectional Lightweight Encapsulation (ULE) mechanism for the transport of IPv4 and IPv6 Datagrams and other network protocol packets directly over the ISO MPEG-2 Transport Stream as TS Private Data. ULE ...

Unidirectional links in an ad hoc network can result from factors such as heterogeneity of receiver and transmitter hardware, power control or topology control algorithms, or differing sources of interference or jamming. Previously proposed metrics for evaluating the difficulty of a unidirectional scenario are limited in scope and are frequently misleading. To be able to analyze ad hoc network ...

We review and illustrate our recent results on globally stable synchronization in directed oscillator networks. We consider asymmetrically connected networks with node balance, the property that the sum of the coupling coefficients of all edges directed to a node equals the sum of the coupling coefficients of all the edges directed outward from the node. We show that for such directed but node ...

Through sequential electrospinning, a sandwich Janus membrane (PU-(CA/PU)-CA) was constructed with hydrophobic polyurethane (PU) nanofiber as the top layer, cellulose acetate/polyurethane (CA/PU) blend intermediate transition layer and hydrophilic acetate (CA) bottom layer. The effects of structure, composition thickness on mechanical properties, permeability separation ability PU-(CA/PU)-CA we...

WiFi’s physical layer has increased in speed from 802.11b’s 11 Mbps to the Gbps rates of emerging 802.11ac. Despite these gains, WiFi’s inefficient MAC layer limits achievable end-to-end throughput. The culprit is 802.11’s mandatory idle period before each medium acquisition, which has come to dwarf the duration of a packet’s transmission. This overhead is especially punishing for TCP traffic, ...

The unidirectional transmission technology is designed to protect the confidentiality of data on the high assurance network. It allows data to transmit only in one direction and prevents the use of acknowledgements or other connection-oriented mechanisms. This makes packet loss become a key issue in unidirectional transmission because of its influence on reliability and performance. In this pap...

Composite Wound Dressings In article 2202685 by Peng Yan, Xinguo Hou, and co-workers, a novel sandwich-structured composite wound dressing (SCWD), integrating superlyophobic polydimethylsiloxane layer, superlyophilic gauze lyophobic PDMS with particular unidirectional drainage capability anti-adhesion properties, is presented. The application of SCWDs can reduce infection, avoid tissue avulsion...
