The SiC MOSFET has lower conduction loss and switching than the Si IGBT, which helps to improve efficiency power density of converter, especially for those having strict requirements volume weight, example, electrical vehicles (EVs), on-board chargers (OBCs), traction drive systems (TDS). However, faster speed will cause overshoot oscillation problems, affect security devices electronic systems...

This paper describes a high-speed, robust, scalable, and low-cost feed-forward time amplifier that uses phase detectors and variable delay lines. The amplifier works by detecting the time difference between two rising input edges with a phase detector and adjusting the delay of the variable delay line accordingly. A test chip was designed and fabricated in 65 nm CMOS. The measured resulting per...

background: the purpose of this study was to compare patient delay, diagnosis delay and treatment delay in breast cancer patients of selected public and private health centers in tehran, iran. methods: in this cross-sectional study, female patients with newly diagnosed breast cancer in a public medical complex and a private breast clinic within one year were included. patient delay was consider...

The demands of System-on-Chip (SoC) interconnect increasingly cannot be satisjed through the use of a shared bus. A common alternative, using unidirectional, point-to-point connections and multiplexers, results in much greater area requirements and still suffersfrom some of the same problems. This paper introduces a delay-insensitive, asynchronous approach to interconnect over long paths using ...

Intimacy is a cellular turn-on he simple act of coming closer together ignites signaling pathways in epithelial cells, as shown and colleagues. The results describe how cells might activate cellular responses to T mechanical stress. Cells are pushed closer together by physical forces. In the lung, for instance, epithelial cells feel the pressure from underlying muscle tissue, particularly in as...

It has been long understood that creative approaches can increase student engagement in learning. However, recent research has started to uncover a clear impact upon learning progression and transforming student understanding across disciplines. This paper details a series of case studies from the JuxtaLearn project conducted across Europe in schools and HE. The results show an increase in stud...

An all-digital on-chip delay measurement (OCDM) architecture with high delay measurement resolution and low supply voltage sensitivity for efficiently detection and diagnosis in the high performance system-on-chip (SoC) applications is presented. Based on the proposed differential delay line pair (DDLP) and an cascadestage delay line, the quantization resolution of the proposed OCDM not only ha...

The drastic increase in the data requirements of scientific applications combined with an increasing trend towards collaborative research has resulted in the need to transfer large amounts of data among the participating sites. The general approach to transferring such large amounts of data has been to either dump data to tapes and mail them or employ scripts with an operator at each site to ba...

Experimental A stainless steel ultra high vacuum (UHV) chamber, pumped by a turbo molecular pump backed by a mechanical pump, providing a base pressure of 5X10 torr after bake out, was used for temperature programmed desorption (TPD) experiments with a typical heating rate of 2.5 K/s. Samples could be cooled below 100 K via a liquid nitrogen dewar and heated up to 1300 K via resistive heating. ...
