The Golden Ratio (a ratio of ~1.618:1) appears repeatedly in nature including structural and functional traits of organisms (e.g. Fibonacci spirals of snail shells and certain seed heads), the spiraled shape of galaxies and hurricanes, and even in much cultural architecture and art. In the mid-19th century, branching structures in plant and animal vascular systems were found to follow the Golde...

In recent years, the rapid growth of new-generation wireless networks has spurred a research thrust in cooperative communication and it is a powerful physical layer technique to combat fading in wireless relaying scenario. Recently, chaos based communication with its excellent features has been proved to be an appropriate choice for the emerging wireless networks. Different chaos based modulati...

In the past two decades, under the conditions that both the osmotic pressure ∆p and tensile stress λ equal zero, a rigorous solution (RS) of human red blood cell (RBC) with a minus spontaneous curvature c0 has been derived with Helfrich model. And, by fitting with observed shapes of RBC, c0R0 has been predicted to be -1.62 as minus golden ratio, where R0 is the radius of a sphere with the same ...

Introduction Realtime MRI involves an inevitable trade-off between spatial resolution, temporal resolution, field-of-view (FOV), and signal-to-noise (SNR) ratio. In conventional Cartesian imaging all these parameters are fixed prior to scanning, and images can typically only be reconstructed for the prescribed parameters. Previously, Winkelmann [1] demonstrated the Golden Angle radial technique...

Human detection is an important topic that can be used for many applications, it is mainly found in areas that required surveillance such as airports, casinos, factories, construction and mining sites. In this paper, a novel human detection method is introduced to extract the human figure from an input image without prior information or training. This method firstly uses a head and shoulder det...

Introduction Compressed Sensing (CS) [1,2] suggests that using nonlinear reconstruction algorithms based on convex optimization an accurate signal reconstruction can be obtained from a number of samples much lower than required by the Nyquist limit. Recently, CS was demonstrated for MR imaging from undersampled data [3, 4]. Prerequisites for a good image reconstruction are the image compressibi...
