Molybdenum electrode based flexible biosensor on porous polyamide substrates has been fabricated and tested for its functionality as a protein affinity based biosensor. The biosensor performance was evaluated using a key cardiac biomarker; cardiac Troponin-I (cTnI). Molybdenum is a transition metal and demonstrates electrochemical behavior upon interaction with an electrolyte. We have leveraged...

DNA is generally considered to be chemically rather inert, but self-cleaving DNA molecules have recently been isolated from in vitro selection experiments; their properties advance the idea that, like RNA, DNA can serve as both a catalyst and an information storage medium.

In this paper, we use single negative metamaterials to reduce the electromagnetic interaction between the mobile phone and human head. The specific absorption rate (SAR) in the head can be reduced by placing the metamaterials between the antenna and the head. We design the single negative metamaterials from periodic arrangement of split ring resonators (SRRs), spiral resonators (SRs) and open s...

In the context of the ECAMP IST European project we are designing a virtual community as a means for helping managers from Small Medium size Enterprises (SMEs) to better understand, develop, evaluate and implement ECommerce projects in the B2B area. In the first part of the paper, we evaluate the importance of designing virtual communities addressing SME managers, and in particular how such kno...

The purpose of this paper is to calculate the specific absorption rate (SAR) reduction in muscle cube with metamaterial attachment. The finite-difference time-domain (FDTD) method has been used to evaluate the SAR in a realistic anatomically based model of the muscle cube. We design the single negative metamaterials from periodic arrangement of split ring resonators (SRRS). By properly designin...

Pipelines transporting solid-liquid mixtures are of practical interest to the oil and pipe industry throughout the world. Such pipelines are known as slurry pipelines where the solid medium of the flow is commonly known as slurry. The optimal designing of such pipelines is of commercial interests for their widespread acceptance. A methodology has been evolved for the optimal sizing of a pipelin...

This paper investigates aspects in designing auditory spaces to support novel forms of interaction in virtual spaces. Initial research on human imagined sounds from places has identified ‘expectation’ as an important psychological construct. Instead of designing realistic experience, the paper suggests a user’s sense of presence as a measure of the user’s experience in virtual spaces. The resul...

ECMDB or the Escherichia coli Metabolome Database (http://www.ecmdb.ca) is a comprehensive database containing detailed information about the genome and metabolome of E. coli (K-12). First released in 2012, the ECMDB has undergone substantial expansion and many modifications over the past 4 years. This manuscript describes the most recent version of ECMDB (ECMDB 2.0). In particular, it provides...

Designing a medium access control (MAC) protocol is a key for implementing any practical wireless network. In general, a MAC protocol is responsible for coordinating users in accessing spectrum resources. Given that a user in cognitive radio(CR) networks do not have priority in accessing spectrum resources, MAC protocols have to perform dynamic spectrum access (DSA) functions, including spectru...
