To improve the cognitive radio user’s detection performance and reduce the complexity, this paper composites the Fractal box dimension algorithm and the 3th-order cyclic-cumulate (TCC) algorithm and improves the TCC algorithm, so a novel detection algorithm is proposed that the Fractal box dimension is used when the signal to noise (SNR) is high, while the improved TCC algorithm is used when th...

This paper reports the systems we submitted to the Microblog Track shared in TREC 2014 which focuses on ad hoc retrieval (i.e., retrieving top 1, 000 relevant tweet for every given topic). To address this task, we adopted a two-stage framework, i.e., firstly, we performed query expansion (i.e., expanding relevant inforamtion using pseudorelevance feedback and Google search engine results) to re...

The strict opositivity of 4th order symmetric tensor may apply to detect vacuum stability general scalar potential. For finding analytical expressions (strict) tensor, we reduce its 3rd better deal with it. So, it is provided that several analytically sufficient conditions for the copositivity 3th 2 dimensional (3 dimensional) tensors. Subsequently, applying these conclusions tensors, are prove...

Recent evidence suggests that nasal irrigation with hypertonic saline may be useful as an adjunctive treatment modality in the management of many sinonasal diseases. However, no previous studies have investigated the efficacy of this regimen in the prevention of seasonal allergic rhinitis-related symptoms in the pediatric patient. Twenty children with seasonal allergic rhinitis to Parietaria we...

Abstract Background pacemaker (PMK) implantation is a routinary procedure although it isn’t free from complications, some of with could be life–treathing. Case report: A female 84 years old hypertensive cardiomiopathy and atrial fibrillation on anticoagulation theraphy Dabigatran was subjected (29th Sept) for sick sinus syndrome (SSS) after syncope. The day the chest radiography showed left–api...

Clinical diagnosis of Parkinson's disease (PD) is characterized by the classical features of tremor, bradykinesia and rigidity, which are present only when more than 70%-80% degeneration of dopaminergic (DA) neurons in the substantia nigra. The lack of means for early diagnosis of PD has elicited interest in searching for its risk factors, which, by now, are almost obtained at a single time poi...

The RADARSAT-2 satellite is Canada's next-generation C-band synthetic aperture radar (SAR) satellite launched in December, 2007. RADARSAT-2 products are characterized by the beam mode used by the satellite and the level of processing that has been applied to the data. This paper examines the speckle characteristics observed on RADARSAT-2 dual polarization products. This work is based on two SLC...

OBJECTIVE The aims of this study were to evaluate serum levels of acute phase reactants, such as CRP and cytokines (TNF-α and IL-6) in patients who have undergone thoracotomy and to investigate the effects of flurbiprofen on postoperative inflammatory response. METHODS Forty patients undergoing posterolateral thoracotomy were randomly divided into 2 groups of 20 each. Control group received t...
