The rapid growth of multi-media and data rich applications has driven the bandwidth demand for long-haul fiberoptic links at unprecedented rates. At the same time, growing capacity demands also imposes challenges on bandwidth and interconnects in data centers. Optical fibers are continuing improving their performance to meet the bandwidth demand in both long haul and short reach applications. W...

Response adaptation is a general characteristic of neurons. A number of studies have investigated the adaptation characteristics of auditory-nerve fibers, which send information to the brain about sound stimuli. However, there have been no previous adaptation studies of olivocochlear neurons, which provide efferent fibers to hair cells and auditory nerve dendrites in the auditory periphery. To ...

This research studied the influence of three types open (short-straight, long-straight, semicircular) and different shapes closed steel fibers (triangular, rectangular, circular) with fiber contents by volume (0, 0.5%, 1%, 1.5%, 2%) on working mechanical performance reactive powder concrete (RPC). The results indicated that (1) number enclosed area formed would remarkably impact RPC; (2) semici...

A mathematical model describing the dissolution and disintegration of long fibers and the clearance of short fibers is developed. For short fiber clearance, the model is based on previous modeling of the retention and clearance of particles, and most model parameters are taken from that particulate model. In addition to modeling the disappearance of long fibers, the present study includes a qua...

The transretinal pathway of optic nerve fibers in the retinas of cynomolgus and bonnet monkeys was studied by light microscopy following small intraretinal injections of horseradish peroxidase (HRP). Injections of HRP into nerve bundles at the optic disc labeled a few ectopic ganglion cells, in addition to those in the related retinal sector. Injections into nerve bundles in the retina labeled ...

At first step polymer optical fibers (POFs) are used in short distance for optical data transmissions. At second step SiO2 nanoparticles were prepared by sonochemical-assisted method. Silica nanoparticles were added to polymer matrix to prepare polymer based nanocomposites. Most of the POF applications are in the medical and electrical devices. There are several methods for fabrication of POFs,...

The integrity of structural connectivity in a functional brain network supports the efficiency of neural processing within relevant brain regions. This study aimed to quantitatively investigate the short- and long-range fibers, and their differential roles in the lower cognitive efficiency in aging and dementia. Three groups of healthy young, healthy older adults and patients with Alzheimer's d...

A number of studies have shown that glass fibers induce both malignant mesothelioma and fibrosis in rats and that these reactions may be primarily a function of the physical properties of the fiber. However, these studies were carried out with fibers having broad size distributions and used methods of administration which bear little resemblance to the way man is exposed. To better characterize...
