Optimization of Impedance Plane Reducing Coupling between Antennas
(Scientific Research Publishing, 2011-01)This paper provides a solution for the design optimization of two-dimensional impedance structures for a given elec-tromagnetic field distribution. These structures must provide electromagnetic compatibility between antennas ... -
Optimization of Threshold for Energy Based Spectrum Sensing Using Differential Evolution
(Scientific Research Publishing, 2011-07)Interference threshold based on energy setting in cognitive radios is a non-convex optimization problem [4]. The convergence of optimization techniques like Genetic algorithm (GA) takes several iterations to fix this ... -
Organ Transplant Trade: A Moral Examination
(Scientific Research, 2015-05)This article normatively discusses two moral theories namely: Ubuntu and Deontology, with the aim of arguing against the practice of organ transplant trade. It is argued that this practice violates a rule of categorical ... -
The origin of biological information and programmed protein synthesis
(Scientific Research Publishing, 2013-10)Biological information is one of the most important characteristics of life, and it enables life to evolve to higher complexity and adapt to the environment by mutation and natural selection. However, the origin of this ... -
Our Experience in 33 Patients of Multiple Ventricular Septal Defect Closure
(Scientific Research, 2015-10)Study: Retrospective study of 33 patients with multiple VSD during March 2009 to March 2014. Technique: The defects were located by injecting the cardioplegia solution into left atrium after occluding the pulmonary artery. ... -
Outcomes of Open Surgery for Popliteal Artery Aneurysms: An 18-Year Experience in a Single Institution in Japan
(Scientific Research, 2018-03)Objective: To elucidate the outcomes of open surgery for popliteal artery aneurysm (PAA) in a single Japanese institution. Materials and Methods: Between 1999 and 2016, 35 patients (44 PAAs) underwent open surgery in ... -
Oxidized phospholipids modify plasminogen and apolipoprotein(a): Implications for vascular disease
(Scientific Research Publishing, 2012-04)Whereas the close structural homology between human plasminogen and apolipoprotein(a) has been known for a number of years only recent studies have revealed that both proteins carry linked oxidized phospholipids that may ... -
P2P Model Based on Isolated Broadcast Domains
(Scientific Research Publishing, 2012-04)Resource location is the most important issue for Peer-to-Peer (P2P) system and flooding is the fundamental mechanism for unstructured P2P systems. Redundant messages will exponential growth with flooding scope increasing ... -
