In a wireless network, messages need to be sent on in an optimized way to preserve the energy of the network. A minimum connected dominating set (MCDS) offers an optimized way of sending messages. However, MCDS construction is a NP-Hard problem. In this paper, we propose a new degree-based greedy approximation algorithm named as Connected Pseudo Dominating Set Using 2 Hop Information (CPDS2HI),...

Recent research ([12][15][19]) shows that the flooding mechanism (for topology update or route request) used in existing protocols for ad hoc wireless networks greatly degrades the network capacity. If we force the effective broadcasts of control packets happen in a small subset of hosts in the network, the protocol overhead caused by global flooding can be substantially reduced. This is the ba...

Epilepsy-associated malformations of cortical development (MCDs) comprise a variety of dysplastic and neoplastic lesions of yet undetermined molecular pathology. Histopathologic similarities between MCDs and dysplastic brain lesions in the autosomal inherited neurocutaneous phacomatosis tuberous sclerosis (TSC), which affects the TSC1 and/or TSC2 genes, suggest common pathogenetic mechanisms. P...

Business intelligence applications ranging from stock market tickers to strategic supply chain adaptation systems require the efficient support of multi-criteria decision support (MCDS) queries. Skyline queries are a popular class of MCDS queries that have received a lot of attention recently. However, a vast majority of skyline algorithms focus entirely on the input being a single data set. In...

The progression of glioblastoma (GBM) is driven by dynamic alterations in the activity and connectivity of gene pathways. Revealing these dynamic events is necessary in order to understand the pathological mechanisms of, and develop effective treatments for, GBM. The present study aimed to investigate dynamic alterations in pathway activity and connectivity across radiotherapy and chemoradiatio...

Purpose: To quantify the DNA damage induced in a clinical megavoltage photon beam at various depths in and out of the field. Methods and Materials: MCNPX was used to simulate 10x10 cm and 20x20 cm 10 MV photon beams from a clinical linear accelerator. Photon and electron spectra were collected in a water phantom at depths of 2.5, 12.5 and 22.5 cm on the central axis and at off-axis points out t...

A multiresolution technique for biomedical image interpolation is presented in this paper. It is an extension of the work on Directional Coherence Interpolation (DCI) [15] – a novel gray-level image interpolation method that interpolates the missing image data along the smoothed Maximum Coherence Directions (MCDs). We propose to apply a pyramidal search strategy for MCD estimation. This coarse-...

A mobile ad hoc network is a collection of wireless mobile nodes forming a temporary network without the support of any established infrastructure or centralised administration. Mobile ad hoc networks face a lot of challenges for designing a scalable routing protocol due to their natural characteristics. The IDea of virtual backbone routing has been proposed for efficient routing in mobile ad h...

Neurodevelopmental insults leading to malformations of cortical development (MCD) are a common cause of psychiatric disorders, learning impairments and epilepsy. In the methylazoxymethanol (MAM) model of MCDs, animals have impairments in spatial cognition that, remarkably, are improved by post-weaning environmental enrichment (EE). To establish how EE impacts network-level mechanisms of spatial...
