∗ Partially supported by FAPESP (under grants 96/12372-2 and 97/14449-5) and CPqD-Telebrás (contracts 7500/856/97 and 7800/825/97). Abstract – This paper presents a realistic model for Ethernet LAN Traffic that takes into account the network constraints. The design of the model is presented along with a brief description of SimATM, an ATM network simulator developed at UNICAMP. The resulting se...

Salicylhydroxamic acid (SHAM), an inhibitor of alternative oxidase (AOX), blocks salicylic acid-induced resistance to tobacco mosaic virus (TMV) but does not inhibit pathogenesis-related PR-1 protein synthesis or resistance to fungal and bacterial pathogens. We found that the synthetic resistance-inducing chemical 2, 6-dichloroisonicotinic acid also induced Aox transcript accumulation and SHAM-...

The spreading dynamic of the 2004 dengue fever outbreak that occurred in Tartagal, Northwestern Argentina, was investigated. A total of 487 suspected dengue cases were recorded and geo-referenced. Maps of daily cases were generated for the 109 days of the outbreak. The epidemic affected the majority of the city within 11 days. The age-distribution of the cases was different from the population ...

Imogolite is a naturally occurring aluminosilicate clay mineral with a nanotube structure. In this study, synthetic imogolite nanotubes were applied to cell culture and the properties as scaffold were compared with those of a conventional culture dish and the carbon nanotube scaffold. The surface characteristics of the imogolite scaffold were drastically changed with the amount of imogolite on ...

Blockchain technology has allowed many abnormal schemes to hide behind smart contracts. This causes serious financial losses, which adversely affects the blockchain. Machine learning mainly been utilized enable automatic detection of contract accounts in recent years. In spite this, previous machine methods have suffered from a number disadvantages: first, it is extremely difficult identify fea...

Vesicle adhesion and fusion to interfaces are frequently used for the construction of biomimetic surfaces in biosensors and drug delivery. Ubiquitous in cell biology, vesicle fusion involves the transformation of two separate membranes into one contiguous lipid bilayer. In distinction, the deposition of vesicle membranes to hydrophobic surfaces requires the transformation of a lipidic bilayer i...

Spreading of neutrophils on protein-coated surfaces is a pivotal event in their ability to respond to soluble, physiologic agonists by releasing large amounts of hydrolases and oxidants. Using neutrophils plated on serum-, fibrinogen- or fibronectin-coated surfaces, we investigated the effect of human serum albumin (HSA) on spreading-dependent neutrophil responses. HSA suppressed the respirator...

The problem of deciding what is implied by a written text. of “reading between the lines” is the problem of text Inference. To extract proper inferences from a text requires a great deal of generol knowledge on the port of the reader. Past approaches have often used a “strong method” tuned to process a particular kind of knowledge structure (such OS a script, or a plan). The alternative is a “w...
