Analysis of extended busy tone performance for coexistence between WRAN and WLAN TVWS networks
(Institute of Electrical and Electronics Engineers, 2015)
TV White Spaces indicate spectrum bands, which were reserved for licensed terrestrial TV broadcasting and opened to unlicensed use under regulatory conditions. One important regulation which is common in all regulatory ...
Achieving secure communication through pilot manipulation
(Institute of Electrical and Electronics Engineers, 2015)
Raising concerns about the security of wireless communication led researchers develop new concepts to keep information secret from eavesdroppers. Among them, physical layer security relies on the features of the wireless ...
Suppressing alignment: An approach for out-of-band interference reduction in OFDM systems
(Institute of Electrical and Electronics Engineers, 2015)
In this work, we introduce a novel approach, called suppressing alignment, to reduce the out-of-band (OOB) interference of orthogonal frequency division multiplexing (OFDM) systems. Suppressing alignment exploits the ...
A survey: Spoofing attacks in physical layer security
(IEEE Computer Society, 2015)
Increasing demand on wireless communications also increases the issues related to communication security. Among different security solutions, physical layer security have recently been gaining many interests by the ...
Air-Ground Doppler-delay spread spectrum for dense scattering environments
(Institute of Electrical and Electronics Engineers, 2015)
Applications using Air-Ground communications are expected to grow in the future. Low altitude phases of these wireless links are considered sever channels, as they experience huge delay and Doppler spreads, however, they ...
Nucleotide sequence alignment and compression via shortest unique substring
(Springer Verlag, 2015)
Aligning short reads produced by high throughput sequencing equipments onto a reference genome is the fundamental step of sequence analysis. Since the sequencing machinery generates massive volumes of data, it is becoming ...
Range selection queries in data aware space and time
(Institute of Electrical and Electronics Engineers, 2015)
On a given vector X = (x<inf>1</inf>, x<inf>2</inf>, , x<inf>n</inf>) of integers, the range selection (i, j, k) query is finding the k-th smallest integer in (x<inf>i</inf>, x<inf>i+1</inf>, , x<inf>j</inf>) for any (i, ...
Predictive risk factors in the treatment of gestational diabetes mellitus
(Sage Publications, 2015)
OBJECTIVE: This study aims to investigate predictive risk factors in the treatment of gestational diabetes mellitus (GDM). PATIENTS AND METHODS: A total of 256 pregnant tvomen who underwent 75 g oral glucose tolerance test ...

Purpose: Temporal lobe epilepsy (TLE) is the most frequent type of localization relatedfocalepilepsyseeninhumans.Ithasafrequencyrate of 30–35% among all epilepsies, and comprises 70% of intractable epilepsies. With hippocampal ...
Surgical correction of cor triatriatum sinister in the paediatric population: mid-term results in 15 cases
(Oxford University Press, 2015)
OBJECTIVES: Cor triatriatum sinister (CTS) is a rare developmental cardiac abnormality resulting in left ventricular inflow obstruction. In this report, we aimed to present our mid-term results of early childhood patients ...
