This paper studies interference alignment scheme and minimum mean square error (MMSE) improvement in Internet of Things (IoT)-oriented cognitive systems, where IoT devices share the licensed spectrum by cognitive radio in spectrum underlay. Target to manage the inter-tier interference caused by cognitive spectrum sharing as well as ensure an MMSE at receivers, the interference alignment algorit...

Simple ontology alignments, largely studied, link one entity from a source ontology to one entity of a target ontology. One of the limitations of these alignments is, however, their lack of expressiveness which can be overcome by complex alignments. Different approaches for generating complex alignments have emerged in the literature [4,5,6]. However, there is a lack of datasets on which they c...

abstract background: triple therapy with a proton pump inhibitor, clarithromycin and amoxicillin and quadruple therapy with a proton pump inhibitor, bismuth citrate, metronidazole and amoxicillin have been proposed in maastricht 2000 as the optimal treatment of helicobacter pylori infection. we aimed to compare these two regimens in iranian pediatric patients. methods: a randomized clinical tri...

Transition-state structures of human and bovine of purine nucleoside phosphorylases differ, despite 87% homologous amino acid sequences. Human PNP (HsPNP) has a fully dissociated transition state, while that for bovine PNP (BtPNP) has early SN1 character. Crystal structures and sequence alignment indicate that the active sites of these enzymes are the same within crystallographic analysis, but ...

triple helix model (th) collaborations involving university, industry and government provide a networked infrastructure for shaping the dynamic fluxes of knowledge base of innovations locally and these fluxes remain emergent within the domains. in this article first the knowledge-based economy, national system of innovation, and three models of uig relations which represent different triple hel...

We discuss first-order electroweak phase transition in models with extended Higgs sectors for the case relatively heavy additional scalar bosons. first show that, by combination of sphaleron decoupling condition, perturbative unitarity and vacuum stability, mass upper bounds on bosons can be obtained at TeV scale even alignment limit where lightest boson behaves exactly like SM tree level. then...

background and aim: bacterial elimination from root canal system is one of the aims in endodontic treatments, so the addition of antibiotics to sealers can increase their antimicrobial efficacy, as in this study we are determining the in-vitro antimicrobial effect of ah26 and ah plus sealers mixed with amoxicillin, triple antibiotic pastes and nanosilver on enterococcus faecalis. materials and ...
