Wideband spectrum sensing is an essential functionality for cognitive radio networks. It enables cognitive radios to detect spectral holes over a wideband channel and to opportunistically use under-utilized frequency bands without causing harmful interference to primary networks. However, most of the work on wideband spectrum sensing presented in the literature employ the Nyquist sampling which...

Today’s, a common problem in cities is increasing delay and reducing the speed of traffic. On the other wise increasing costs of acquisition in urban area are not allow new routes and highways. Also construction of new highway or street such as Imam Ali highway and Sadr highway in Tehran lead to develop new applications (such as BRT lane ,…) And become quickly saturate and less eff...

  Background :Severe neonatal hyperbilirubinemia is associated with significant morbidity and mortality. This study was conducted to investigate the causes of severe hyperbilirubinemia leading to Exchange Transfusion (ET) from March 2009 to March 2011 in Bahrami children hospital, Tehran, Iran in order to establish guidelines to prevent profound jaundice & ET.   Methods : 94 neonates underwent ...

Suboptimal nitrogen (N) availability is a primary constraint for crop production in developing nations, while in rich nations, intensive N fertilization carries substantial environmental and economic costs. Therefore, understanding root phenes that enhance N acquisition is of considerable importance. Structural-functional modeling predicts that root cortical aerenchyma (RCA) could improve N acq...

Let F ⊆ H ⊆ G be closed subgroups of a locally compact group. In response to a 1972 question by Eymard, we construct an example where the homogeneous factor space G/F is amenable in the sense of Eymard–Greenleaf, while H/F is not. (In our example, G is discrete.) As a corollary which answers a 1990 question by Bekka, the induced representation indGH(ρ) can be amenable in the sense of Bekka even...

This Adverse Outcome Pathway (AOP) describes the linkage between Deiodinase 1 inhibition and increased mortality via reduced anterior swim bladder inflation. The is a gas-filled organ found in many bony fish species typically consists of two chambers. posterior chamber inflates during early development (embryo), while late (larva). Both chambers are important for to control buoyancy has an addi...
