First record, taxonomy and temporal/spatial dispersion pattern of species in genus Pontella (Crustacea:Copepoda:Calanoida) from coastal/estuarine waters Bushehr

PURPOSE Previous study has shown that the absence of uroplakin II can cause urinary tract dysfunction, including vesicoureteral reflux and renal abnormalities, as well as micturition pattern changes. We developed a simple surrogate measure of bladder function using ultraviolet visualization of urinary voiding patterns in a uroplakin II knockout mouse animal model. MATERIALS AND METHODS Three ...

Nuclear fragmentation is a common feature in many neurodegenerative diseases, including Alzheimer's disease (AD). In this study, we show that nuclear lamina dispersion is an early and irreversible trigger for cell death initiated by deregulated Cdk5, rather than a consequence of apoptosis. Cyclin-dependent kinase 5 (Cdk5) activity is significantly increased in AD and contributes to all three ha...

A widely-cited study investigating effects of recognition difficulty on the phonetic realization of words (Wright, 1997, 2004) described vowel dispersion in a subset of the Easy/Hard database (Torretta, 1995). The core finding was that vowel dispersion, i.e. distance from the center of the talker’s F1/F2 space, was greater in words that represent difficult recognition targets, due to competitio...

The 2 rare entities, pigmentary dispersion syndrome and pigmented pattern dystrophy of the retinal pigment epithelium, were found in a young male patient. Visual function was undisturbed.

We consider that Optical communication network offers very high potential bandwidth and flexibility In terms of high bit-rate transmission. However, their performance slows down due to some parameter like dispersion, attenuation, scattering and unsynchronized bit pattern. In long haul application, dispersion is the main parameter which needs to be compensated in order to provide high level of r...

The dynamical evolution of pulses in Kerr media with parabolic index profile is examined. It is found that when dispersion and graded-index have opposite signs propagating pulses exhibit an oscillatory pattern, similar to a breathing behavior. Furthermore, if the pulse and the index profile are not aligned the pulse oscillates around the index origin with frequency that depends on the values of...

Adaptive optics is used to compensate for modal dispersion in digital transmission through multimode fiber (MMF). At the transmitter, a spatial light modulator (SLM) controls the launched field pattern. An estimate of intersymbol interference (ISI) caused by modal dispersion is formed at the receiver and fed back to the transmitter, where the SLM is adjusted to minimize ISI. Error-free transmis...
