Diesel particulate filter (DPF) has been widely applied as the efficient way to reduce the soot emissions from diesel engines. The oxidation of the accumulated soot layer in the particulate filter, known as DPF regeneration, plays a crucial role in the diesel engine operation. It is important to understand the characteristics and fundamentals of this process. A 2D timedependent diesel particula...

Nervous necrosis virus (NNV) is a member of the Betanodavirus genus that causes fatal diseases in over 40 species of fish worldwide. Mortality among NNV-infected fish larvae is almost 100%. In order to elucidate the mechanisms responsible for the susceptibility of fish larvae to NNV, we exposed zebrafish larvae to NNV by bath immersion at 2, 4, 6, and 8 days postfertilization (dpf). Here, we de...

This paper presents a distinctive phonetic features (DPFs) based phoneme recognition method by incorporating syllable language models (LMs). The method comprises three stages. The first stage extracts three DPF vectors of 15 dimensions each from local features (LFs) of an input speech signal using three multilayer neural networks (MLNs). The second stage incorporates an Inhibition/Enhancement (...

PURPOSE To evaluate in vitro the capture efficiency of a distal protection filter (DPF) used during carotid artery stenting and examine the longitudinal vascular impedance in the presence of a DPF. METHODS Four approved DPFs (Spider RX, FilterWire EZ, RX Accunet, and FiberNet) were evaluated in a physiologically realistic in vitro setup. A pulsatile programmable piston pump circulated a blood...

Zebrafish (Danio rerio) possess a great promise in evaluating the toxicity of nanoparticles (NPs). The commonly used method on zebrafish was to calculate mortality and 5 or 6 days postfertilization (dpf) toxicity scores. However, this method could only reveal a general toxic level. To further distinguish the toxicity of NPs in the same general level, a more systematic and sensitive approach nee...

This paper describes two systems to recover the Internet connectivity impaired by private networks and firewalls. These devices cause asymmetry in the Internet, making peer-to-peer computing difficult or even impossible. The Condor system is one of those that are severely impaired by the asymmetry. Compared to normal peer-to-peer computing applications, Condor has stricter requirements, which a...

The infrequently feeding Burmese python (Python molurus) experiences significant and rapid postprandial cardiac hypertrophy followed by regression as digestion is completed. To begin to explore the molecular mechanisms of this response, we have sequenced and assembled the fasted and postfed Burmese python heart transcriptomes with Illumina technology using the chicken (Gallus gallus) genome as ...

Metal–insulator–metal (MIM) capacitors have been fabricated using high-κ La2O3\HfO2 dielectric stacks deposited using Dense Plasma Focus (DPF) and were subsequently studied. DPF is a unique machine used for the very first time to fabricate dielectric stacks within a MIM structure as it can be used both to deposit nano-size thin film as well as can also be used to change the properties of the po...

For the purpose of designing a reasonable control strategy for DOC-assisted DPF regeneration, mathematical model that describes thermal phenomenon both in diesel oxidation catalyst (DOC) and particulate filter (DPF) during regeneration is developed. All boundary conditions this are obtained by experiments. The effects main exhaust parameters such as mass flow rate, temperature, oxygen concentra...
