This paper describes a clock and data recovery (CDR) circuit that supports dual data rates of 2.7Gbps and 1.62Gbps for DisplayPort standard. The proposed CDR has a dual mode voltage-controlled oscillator (VCO) that changes the operating frequency with a “Mode” switch control. The chip has been implemented using 0.18μm CMOS process. Measured results show the circuit exhibits peak-to-peak jitters...

The rheological regulation of the “three high” (high temperature, high density and high salinity) water-based drilling fluid is a worldwide problem due to the combined influence of temperature, solid content and salinity. This paper investigates the factors and regulation methods about rheological property of “three high” water based drilling fluid, and the effects of clay, salinity and weighti...

background: spinal cord injury (sci) is a major clinical condition and research is commonly done to find suitable treatment options. however, there are some degrees of spontaneous recovery after sci and gender is said to be a contributing factor in recovery, but this is controversial. this study was done to compare the effects of sexual dimorphism on spontaneous recovery after spinal cord injur...

A closed-form series solution formula for the problem of optimal portfolio diversification under dynamic (possibly, long-term-memory) appreciation rate uncertainty, for an investor with HARA utility, is discovered. To that end a calculus of variations method, recently introduced by the author, was extended. The usefulness of the obtained result is examined by means of solving a few guiding exam...

gravity drainage is one of the important recovery mechanisms in fractured carbonate and conventional reservoirs. it occurs due to density difference between the gas in fracture and the oil in matrix as well as in conventional tilted reservoirs. oil phase will form films which are produced under gravity forces (film flow). many gas injection experiments have been done on laboratory scales with d...

The Gaia satellite was selected as a cornerstone mission of the European Space Agency (ESA) in October 2000 and confirmed in 2002 with a current target launch date of 2011. The Gaia mission will gather on the same observational principles as hipparcos detailed astrometric, photometric and spectroscopic properties of about 1 billion sources brighter than mag V = 20. The nature of the measured ob...

This is a PDF file of a manuscript that has been accepted for publication in an American Accounting Association journal. It is the final version that was uploaded and approved by the author(s). While the paper has been through the usual rigorous peer review process for AAA journals, it has not been copyedited, nor have the graphics and tables been modified for final publication. Also note that ...
