in this paper, a numerical study is performed to provide the combustion and emission characteristics resulting from fuel-reactivity controlled compression ignition (rcci) combustion mode in a heavy-duty, single-cylinder diesel engine with gasoline and diesel fuels. in rcci strategy in-cylinder fuel blending is used to develop fuel reactivity gradients in the combustion chamber that result in a ...

Asthma is a complicated disorder, whose prevalence has increased over the past few decades.Asthma is characterized by infiltration of inflammatory leukocytes along with enhancedproinflammatory cytokines and chemokines. Fungi are now far more widely being considered as thedominant extrinsic trigger for asthma. Fungi are linked to the severity of asthma in many ways. Somedifferences between studi...

background: association between helicobacter pylori (hp) infection and migraine and the effect of hp eradication on relief of migraine headache have been studied but the results are controversial. objectives: to evaluate the effect of hp eradication in treatment of patients affected by migraine. materials and methods: eighty consecutive hp infected patients affected by migraine without aura wer...

The silicon-on-insulator (SOI) CMOS technology has a number of advantages over the standard bulk CMOS technology, such as no latch-up effect, high speed and low power. The fully depleted SOI (FD-SOI) technology provided by OKI Electric Industry Co., Ltd. is realizing the full features of the advantages with lowest junction capacitance. Test element group (TEG) structures of transistors were fab...

This work introduces the use of GradedChannel SOI MOSFETs to make analog current mirrors and compare their performance with those made with conventional fully depleted SOI transistors. It is demonstrated that Graded-Channel MOSFETs can provide higher precision current mirror with enhanced output swing. Also lesser modifications of the output characteristics due to the self-heating effect than i...

A current-mode output driver that supports SERDES applications is implemented using 0.13 μm Bulk and PD SOI CMOS technologies. Schematic simulation results confirm the enhanced performance of PD SOI for very high-speed interfaces. The PD SOI current-mode driver shows a 3 times lower data dependent jitter than the Bulk current-mode driver at the same 3.125 Gbps data rate of XAUI standard.

BACKGROUND The utility of hyperbaric oxygen therapy (HBOT) in the treatment of necrotizing soft tissue infections (NSTIs) has not been proved. Previous studies have been subject to substantial selection bias because HBOT is not available universally at all medical centers, and there is often considerable delay associated with its initiation. We examined the utility of HBOT for the treatment of ...

A new small-signal model for fully depleted silicon-oninsulator (FD-SOI) MOSFETs operating at RF frequencies is presented. The model accounts for the non-quasi-static effect by determining model parameters using a curve fitting procedure to reproduce the frequency response of FD-SOI MOSFETs. The accuracy of the model is validated by comparison of S parameters with measured results in the range ...

The authors report a 0.7V Manchester carry look-ahead circuit using partially depleted (PD) SOI CMOS dynamic threshold (DTMOS) techniques for low-voltage CMOS VLSI systems. Using an asymmetrical dynamic threshold pass-transistor technique with the PD-SOI DTMOS dynamic logic circuit, this 0.7V PD-SOI DTMOS Manchester carry look-ahead circuit has an improvement of 30% in propagation delay time co...

We present a silicon-on-insulator (SOI) pass-transistor logic (PTL) gate with an active body bias control circuit and compare the proposed PTL gate with other types of PTL gates with different body bias circuits in two different 0.13μm SOI CMOS technologies. The experimental results show that the proposed SOI PTL gate using the body bias controlled technique is superior in terms of performance ...
