Origins of scaling in genetic code
(2011)The principle of least effort in communications has been shown, by Ferrer i Cancho and Sol´e, to explain emergence of power laws (e.g., Zipf’s law) in human languages. This paper applies the principle and the informationtheoretic ... -
The origins of the English financial markets : investment and speculation before the south sea bubble
(Cambridge University Press, 2009)In English financial history, the late 1600s was a critical period. Many joint-stock companies appeared creating opportunity for investment in projects that ranged from paper manufacturing to the search for sunken treasure. ... -
Origins of the extragalactic background at 1 mm from a combined analysis of the AzTEC and MAMBO data in GOODS-N
(2011-02-01)We present a study of the cosmic infrared background, which is a measure of the dust-obscured activity in all galaxies in the Universe. We venture to isolate the galaxies responsible for the background at 1 mm; with ... -
The Origins of the Ultramassive White Dwarf GD50
(Astronomical Society of the Pacific, 2007)On the basis of astrometric and spectroscopic data we argue that the ultramassive white dwarf GD 50 is associated with the star formation event that created the Pleiades and is potentially a former cluster member. Its ... -
The Orion Protostellar Explosion and Runaway Stars Revisited : Stellar Masses, Disk Retention, and an Outflow from the Becklin-Neugebauer Object
(2020-02-01)The proper motions of the three stars ejected from Orion's OMC1 cloud core are combined with the requirement that their center of mass is gravitationally bound to OMC1 to show that radio source I (Src I) is likely to have ... -
Orion revisited III. The Orion Belt population
(2017-02-13)This paper continues our study of the foreground population to the Orion molecular clouds. The goal is to characterize the foreground population north of NGC 1981 and to investigate the star formation history in the large ... -
Oscillation-based DFT for Second-order Bandpass OTA-C Filters
(2017-09-06)This paper describes a design for testability technique for second-order bandpass operational transconductance amplifier and capacitor filters using an oscillation-based test topology. The oscillation-based test structure ... -
Oscillation-based DFT for second-order OTA-C filters
(Institute of Electrical and Electronics Engineers (IEEE), 2008)We propose an easily implemented and low-cost design-for-testability scheme for OTA-C filters based on an oscillation-based test (OBT) methodology. The OBT method is a vectorless output test strategy easily applicable to ... -
Oscillation-based Test Method for Continuous-time OTA-C Filters
(Institute of Electrical and Electronics Engineers (IEEE), 2006)Design for testability technique using oscillation-based test topology for KHN OTA-C filters is proposed. The oscillation-based test structure is a vectorless output test strategy easily extendable to built-in self-test. ... -
Oscillation-Based Test Structure and Method for OTA-C Filters
(Institute of Electrical and Electronics Engineers (IEEE), 2006)This paper describes a design for testability technique for operational transconductance amplifier and capacitor filters using an oscillation-based test topology. The oscillation-based test structure is a vectorless output ... -
Oscillatory activity, phase differences, and phase resetting in the inferior olivary nucleus
(2013)The generation of temporal patterns is one of the most fascinating functions of the brain. Unlike the response to external stimuli temporal patterns are generated within the system and recalled for a specific use. To ... -
Osiris deep imaging of cygnus OB2 : The stellar population of the cygnus X central engine
(2013)The young massive cluster Cyg OB2 is the closest massive star forming region to the Sun, with hundreds of OB members, and then the best target in the Milky Way to study the feedback of massive stars on the star formation ... -
The OSTE: Objective Structured Technical Examination for Engineering Students
(2005)Objective Structured Clinical Examination (OSCE) has been widely adopted as an assessment tool in healthcare education. It normally consists of a series of exercises through which students rotate individually and are marked ... -
Osteoporosis : A teenage perspective
(2007-12)Objectives: To assess the knowledge and health beliefs, on osteoporosis, of 16-18 year olds in full-time education in the UK. This is believed to be an age where peak bone mass, a significant factor in osteoporosis and ... -
Osteoporotic fracture and post operative clinical and cost outcomes in rheumatoid arthritis (RA) : results from two UK inception cohorts
(2013-10)379: The risk of osteoporotic fracture is known to be high in RA. Yet less is known about RA related predictive factors for this complication & its associated economic burden -
The Other Shoe: Fragmentation in the Post-medieval home
(2017-05-01)Deposits are not always recovered whole; many are found broken and damaged. The obvious explanation is that such objects were accidentally broken; however, some have been interpreted as having been deliberately damaged by ... -

The Other Side of the Equation: The Demands of Women on Re-entering the Labour Market
(1991)The recent interest in women returning to, or increasing their, labour market participation has largely ignored the skills and aspirations of women themselves. This article is based on a survey of mothers of young children ...
