objective(s) theophylline, a xanthenes derivative, is still widely used as an effective bronchodilator in the management of asthmatic patients. it is used both as a prophylactic drug and to prevent acute exacerbations of asthma. the aim of study was to formulate and evaluate effect of the microencapsulation of theophylline loaded nanoparticles on the reduction of burst release. materials and me...

INTRODUCTION Some forms of tinnitus are considered to be auditory phantom phenomena related to reorganization and hyperactivity of the auditory central nervous system. Repetitive transcranial magnetic stimulation (rTMS) is a non-invasive tool capable of modulating human brain activity, using single pulse or burst stimuli. Burst rTMS has only been performed in the theta range, and has not been u...

We have observed an unusually strong X-ray burst as a part of our regular eclipse timing observations of the lowmass binary system EXO 0748 676. The burst peak flux was 5:2 ; 10 8 ergs cm s , approximately 5 times the normal peak X-ray burst flux observed from this source by RXTE. Spectral fits to the data strongly suggest that photospheric radius expansion occurred during the burst. In this pa...

In OBS networks, lost bursts can be recovered proactively by using burst cloning, or reactively, by using burst retransmission. Burst cloning has advantage of low burst delay but it suffers from low bandwidth utilization. Burst retransmission has advantage of high bandwidth utilization but at the cost of high burst delay. To overcome this problem in star OBS networks, we propose two solutions. ...

This paper presents a lower and upper bound for linear codes which are capable of correcting errors in the form of solid burst of different lengths within different sub blocks. An illustration of such kind of codes has also been provided.

Optical Burst Switching (OBS) has become a mature technology to support the current and next generation Internet over optical network backbones. In OBS networks contention is the main source of burst loss that can reduce the performance of the higher layers. Burst retransmission is a reactive loss recovery mechanism, which attempts to resolve contention by retransmitting the contended burst at ...
