The use of Spatial Division Multiplexing for Microwave Photonics signal processing is proposed and experimentally demonstrated, for the first time to our knowledge, based on the selective inscription of Bragg gratings in homogeneous multicore fibers. The fabricated devices behave as sampled true time delay elements for radiofrequency signals offering a wide range of operation possibilities with...

Marfan syndrome is associated with early death due to aortic aneurysm. The condition is caused by mutations in the gene (FBN1) encoding fibrillin-1, a major constituent of extracellular microfibrils. Prior observations suggested that a deficiency of microfibrils causes failure of elastic fiber assembly during late fetal development. Mice homozygous for a targeted hypomorphic allele (mgR) of Fbn...

concrete shear walls are the most prevalent structural systems resisting lateral loads due to earthquakes in high-rise buildings. very large in-plane stiffness of shear walls provides an excellent drift control in the structure. however, structural damages and early code shortcomings threaten the efficiency of existing structural walls against earthquake. recently, fiber reinforced polymer (frp...

there is a worldwide interest in using fibers of different types in concrete mixtures. in this regard, as the use of pet fibers has gradually increased during the last decade, this study aims to investigate the effects of pet fibers on the mechanical properties of hardened concrete and the workability of fresh concrete. to this end, different contents of pet fibers (pc= %0, %0.5, %1 and %1.5) a...

The purpose of the present study was to determine the relationship between the adaptations in muscle fiber size and the connective tissue content (interfiber area) in atrophying and hypertrophying skeletal muscles. Hypertrophy was induced in the cat plantaris muscle via functional overload (FO,12 weeks) induced via the removal of its major synergists. Atrophy was induced in the cat soleus muscl...

Integration Platform Session: The paper presents on overview of a polymer based hybrid integration platform developed at HHI. The crucial building blocks involved are described, and examples of recently developed components are given. Keywordspolymer waveguides; passive fiber coupling; ultrathin film elements; multiplexer; transceiver; PSK receivers; tunable laser

We present a multi-color STED fluorescence microscope providing far-field optical resolution down to 20 nm for biomedical research. The optical design comprises fiber lasers, beam scanners, and a set of active and passive polarizing elements that cooperatively yield an optically robust system for routinely imaging samples at subdiffraction length scales.

Reinforced concrete (RC) elements lose their structural strength by exposing to fire as the mechanical properties of reinforcing steel and deteriorate due heat. This study provides an understanding behavior three elements: beam, column, slab at high temperatures using a finite element (FE) modelling produced in ABAQUS, well potential retrofitting these Slurry Infiltrated Fiber Concrete (SIFCON)...

A self-consistent formalism is developed for treating propagation of beams in situations which include phase conjugation and nonreciprocal elements. Two equivalent field representations, the rectangular polarization and the circular polarization representation, are considered, and the rules for transforming between them are derived. An example involving a proposed new current fiber sensor is an...
