We present an approach to detect a selfish node in a wireless network by passive monitoring. This does not require any access to the network nodes. Our approach requires deploying multiple sniffers across the network to capture wireless traffic traces among multiple channels. IEEE 802.11 networks support multiple channels and a wireless interface can monitor only a single channel at one time. T...

With the development of human motion capture, realistic human motion capture data has been widely implemented to many fields. However, segmenting motion capture data sequences manually into distinct behavior is time-consuming and laborious. In this paper, we introduce an efficient unsupervised method based on graph partition for automatically segmenting motion capture data. For the N-Frame moti...

Exosomes are lipid nanovesicles released following fusion of the endosoma limiting membrane with the plasma membrane; however, their fate in lymphoid organs after their release remains controversial. We determined that sialoadhesin (CD169; Siglec-1) is required for the capture of B cell-derived exosomes via their surface-expressed α2,3-linked sialic acids. Exosome-capturing macrophages were pre...

In an ad hoc network it may be necessary for a single node to collect information about the local or global state of the network and the devices contained within it. This information may be used in network management, resource and service discovery, and routing protocols. Given ad hoc network constraints, this process of information collection must be efficient, scalable and distributed. Unlike...

Key predistribution is a well-known technique for ensuring secure communication via encryption among sensors deployed in an ad-hoc manner to form a sensor network. In this paper, we propose a novel 2-Phase technique for key predistribution based on a combination of inherited and random key assignments from the given key pool to individual sensor nodes. We also develop an analytical framework fo...

We propose a new authenticated key agreement scheme based on Blom’s scheme, but using multiple master keys and public keys in permutations to compute the private keys in each node. The computations are over a small prime field, and by storing them in a random order in the node, the private-public-master-key associations (PPMka) of the private keys are lost. If a node is captured, the PPMka of t...

Background: The diagnosis of toxocariasis heavily depends on immunological tests because the number of parasites is usually few in infected tissues, unless they migrate into an organ such as eye. In general, patients with ocular toxocariasis have serum anti- T canis antibody titres that are significantly lower than those with visceral toxocariasis. Objective: To diagnose the asymptomatic toxoca...

This paper contributes to the challenging field of security for wireless sensor networks by introducing a keyagreement scheme in which sensor nodes create secure radio connections with their neighbours depending on the aidof third parties. These third parties are responsible only for the pair-wise key establishment among sensor nodes,so they do not observe the physical phenomenon nor route data...

This paper presents a novel algorithm for secure, reliable and flexible transmission of big data in two hop wireless networks using cooperative jamming scheme. Two hop wireless networks consist of source, relay and destination nodes. Big data has to transmit from source to relay and from relay to destination by deploying security in physical layer. Cooperative jamming scheme determines transmis...

Background. To explore the application of serum proteomic patterns for the preoperative detection of regional lymph node involvement of colorectal cancer (CRC). Methods. Serum samples were applied to immobilized metal affinity capture ProteinChip to generate mass spectra by Surface-Enhanced Laser Desorption/ionization Time-of-Flight Mass Spectrometry (SELDI-TOF-MS). Proteomic spectra of serum s...
