To ensure secure content delivery, the Motion Picture Experts Group, MPEG, has dedicated significant effort to the DRM (Digital Rights Management) issues. MPEG is now moving from defining only hooks to proprietary systems (e.g., in MPEG-2, MPEG-4 Version 1) to specifying a more encompassing standard in Intellectual Property Management and Protection (IPMP). MPEG feels that this is necessary in ...

We described here a patient who presented with symptoms of heart failure who was found to have severe bilateral impairment of atrioventricular inflow. Primary cardiac lymphoma (PCL) with extensive involvement of the two atria, pericardium and myocardium is an extremely rare tumor in immunocompetent patients. We report here a case of PCL in an immunocompetent patient with involvement of both atr...

Primary cutaneous lymphomas (PCL) are rare in pediatrics. Mycosis fungoides (MF) is the most frequent PCL diagnosed in childhood. There are various clinical variants of MF, including the hypopigmented MF (HMF). We present a 5-year-old boy with an 18-month history of progressive, generalized, nonpruritic hypopigmented lesions with central lacy erythema. He had no improvement with emollients. Ski...

We obtain a network traffic model for real-time MPEG-II encoded digital video by analyzing video stream samples from real-time encoders from NUKO Information Systems. MPEG-II sample streams include a resolution intensive movie, City of Joy, an action intensive movie, Aliens, a luminance intensive (black and white) movie, Road To Utopia, and a chrominance intensive (color) movie, Dick Tracy. Fro...

In this paper modelling and queuing analysis of variable-bit-rate (VBR) MPEG coded video sources in B-ISDN networks based on ATM are studied. Modelling is performed by examining a low pass version of the aggregate MPEG sequence, capable of capturing the video activity. A discrete state continuous time Markov chain is then proposed to approximate the aggregate MPEG traffic. The previous model is...

Biodegradable scaffolds play an important adjunct role in transplantation of retinal progenitor cells (RPCs) to the subretinal space. Poly(ε-Caprolactone) (PCL) scaffolds with different modifications were subretinally implanted in 28 porcine eyes and evaluated by multifocal electroretinography (mfERG) and histology after 6 weeks of observation. PCL Short Nanowire, PCL Electrospun, and PCL Smoot...

We describe a surgical technique for arthroscopic posterior cruciate ligament (PCL) reconstruction with remnant preservation of the original PCL fibers using a posterior trans-septal portal approach. Using the transtibial technique and the posterior trans-septal portal approach allows good visualization of the tibial tunnel preparation, easy access to the tibial tunnel without neurovascular inj...
