In the context of network capacity planning and management, traffic matrix (TM) estimation plays a crucial role, as it provides the means for computing the volume of traffic that flows between all pairs of nodes in a network. Since the TM estimation problem was first addressed in [13], various techniques for its solution have been introduced based on observed traffic counts on every link in the...

label switching technology is a flexible and high performance method for forwarding layer three packets that are mapped to layer two flows. each label switch router, lsr, needs a specific label for every flow, where the number of labels depends on the mapping and granularity of flows. data and control driven methods are the most significant and popular methods in label mapping policy. the above...

We hypothesized that the intensity of neutrophilic alveolitis is related to establishing a gradient of neutrophil attractant chemokines across the alveolar-capillary barrier. In these experiments, a positive chemokine gradient toward the alveoli was induced by intratracheal instillation of endotoxin in rats (IT LPS). Alteration of the chemotactic gradient was induced by combining IT LPS (0.1 mg...

Recently, Yang and Kieffer’ proposed a novel lossless grammar-based data compression algorithm, called the YK algorithm, in which a greedy sequential grammar transform is applied to the original data to construct an irreducible context free grammar, which is encoded indirectly by using an arithmetic coder. The YK algorithm has been shown to be universal for the class of stationary, ergodic sour...

OBJECTIVE To investigate the effect of timing of dexamethasone administration on auditory hair cell survival following an ototoxic insult with kanamycin and furosemide. STUDY DESIGN Controlled experimental study. SETTING Translational science experimental laboratory. METHODS 5-6 week old CBA/CaJ mice, divided into 6 groups, were injected with kanamycin (1 mg/g SC) followed by furosemide (...

PURPOSE The authors studied the role of the complement system in host defense against Staphylococcus epidermidis and S. aureus endophthalmitis. METHODS Guinea pigs in the S. epidermidis model received an intravitreal injection of 7000 viable organisms, and guinea pigs in the S. aureus model received 50 viable organisms. The experimental animals in each model were decomplemented with intraperi...

OBJECTIVES To evaluate the reliability and validity of the Norfolk Arthritis Register Damaged Joint Count (NOAR-DJC) in patients with early inflammatory polyarthritis (IP). METHODS The NOAR-DJC examines deformity in 51 joints. Deformity is defined as inability to adopt the anatomical position, reduction in range of movement by at least one-third, and/or surgical alteration of the joint. Relia...
