Space-time block codes (STBCs) from non-square complex orthogonal designs are bandwidth efficient when compared with those from square real/complex orthogonal designs. Though there exists rate-1 ROD for any number of transmit antennas, rate-1 complex orthogonal designs (COD) does not exist for more than 2 transmit antennas. Liang (IEEE Trans. Inform. Theory, 2003) and Lu et al (IEEE Trans. Info...
abstract background: pseudoarthrosis of the tibia poses one of the most challenging treatment problems in all of orthopedics. the goal of the study was to assess the clinical outcome of intramedullary rod fixation in its treatment. methods: the results of the management for nine patients with pseudoarthrosis of the tibia with im rod fixation were reviewed retrospectively between 1986 - 2006...
We use some results from the theory of reproducing kernel Hilbert spaces to show that reachable space heat equation for a finite rod with either one or two Dirichlet boundary controls is RKHS analytic functions on square, and we compute its as an infinite double series. also null half line data sector, whose (essentially) sum pullbacks Bergman Hardy kernels plane \(\mathbb {C}^+\).
Reconfigurable nanostructures represent an exciting new direction for materials. Applications of reversible transformations between nanostructures induced by molecular conformations under external fields can be found in a broad range of advanced technologies including smart materials, electromagnetic sensors, and drug delivery. With recent breakthroughs in synthesis and fabrication techniques, ...
The acoustic properties of a three-dimensional sonic crystal made of square-rod rigid scatterers incorporating a periodic arrangement of quarter wavelength resonators are theoretically and experimentally reported in this work. The periodicity of the system produces Bragg band gaps that can be tuned in frequency by modifying the orientation of the square-rod scatterers with respect to the incide...
Background. Antibiotic exposure and specimen volume are known to affect pathogen detection by culture. Here we assess their effects on bacterial pathogen detection by both culture and polymerase chain reaction (PCR) in children. Methods. PERCH (Pneumonia Etiology Research for Child Health) is a case-control study of pneumonia in children aged 1-59 months investigating pathogens in blood, naso...
Localized surface plasmon resonances (LSPRs) in metallic nanostructures have been studied intensely in the last decade. Fano interference is an important way to decrease the resonance linewidth and enhance the spectral detection resolution, but realizing a Fano lineshape with both a narrow linewidth and high spectral contrast-ratio is still challenging. Here we propose a metallic nanostructure ...
A Novel Study on Non-invasive Assessment of Renal Osteodystrophy among Iranian Hemodialysis Patients
Background: Renal osteodystrophy (ROD) is a common bone and mineral metabolism disorder in patients with end-stage renal disease (ESRD). This study aimed to determinate the frequency of the subtypes of ROD and evaluate the diagnostic value of biochemical as the well as radiographic markers for the diagnosis of ROD among hemodialysis patients in Golestan province of Iran. Materials and Methods...
