1 We propose a modification to the basic Deterministic Packet Marking (DPM), a promising IP traceback scheme, to handle fragmented traffic. The modification introduces no additional bandwidth overhead, but limited additional memory requirements and processing overhead on the DPM-enabled interface. Index Terms — Security, IP Traceback

After decades of research involving numerous epidemiologic studies and extensive investigations in laboratory animals, a causal relationship between diesel exhaust (DE) exposure and lung cancer has not been conclusively demonstrated. Epidemiologic studies of the transportation industry (trucking, busing, and railroad) show a small elevation in lung cancer incidence (relative risks [RRs] general...

An experimental and theoretical study was undertaken for three ether glycols (mixtures of isomers). The present paper, being the first part a complex study, reports using static apparatus, namely, vapor–liquid equilibria dipropylene glycol methyl (DPM), n-butyl (DPnB), propylene (PnB), their pseudo-binary mixtures composed (PnB + DPM), (DPM DPnB), aqueous solutions each ether. explored temperat...

An experimentally obtained polarization curve for the hydrogen evolution reaction on silver in a 0.5 mol dm−3 solution was investigated using an electrochemical curve technique named the differential polarization method (DPM). The exchange current density estimated by the Tafel extrapolation method (TEM) and the DPM were compared and assessed from points of simple and more accurate handling. It...

Pavlovian olfactory learning in Drosophila produces two genetically distinct forms of intermediate-term memories: anesthesia-sensitive memory, which requires the amnesiac gene, and anesthesia-resistant memory (ARM), which requires the radish gene. Here, we report that ARM is specifically enhanced or inhibited in flies with elevated or reduced serotonin (5HT) levels, respectively. The requiremen...

The aim of the study was to conduct an analysis of the main symptoms of deep pectoral myopathy (DPM) in broiler chickens, which is manifested by changes in colour and texture of the affected muscle. The research was conducted on Ross508 chicken broilers, at an age of 35-42 d. The lesions were assessed through macroscopic inspection, using colour parameters as well as texture analysis. Furthermo...
