The First Fellow of American College of Surgeons to Come to Korea: Dr. Alfred Irving Ludlow
(1875–1961) dedicated himself to his work as a professor of surgery at Severance Union Medical College. During his travels with L. H. Severance to Korea in 1907 (Fig. 1), Dr. Ludlow attended the meeting of the 15th Presbyterian Council and the First Presbytery of the Presbyterian in Ko-rea and decided to become a medical missionary at the age of 37. By 1912, he had devoted his life to Severance...
متن کاملSimple is not easy
I review and challenge the views on simplicity and its role in linguistics put forward by Ludlow (2011). In particular, I criticize the claim that simplicity—in the sense pertinent to science—is nothing more than ease of use or “user-friendliness”, motivated by economy of (cognitive) labor. I argue that Ludlow’s discussion fails to do justice to the diversity of factors that are relevant to sim...
متن کاملFluvial Stratigraphy and Regional Volcanism at Hypanis Delta , Mars
Introduction: The Hypanis fan-shaped deposit in Xanthe Terra has been interpreted by many to be a late Noachian aged delta along the dichotomy boundary [15]. The putative delta was a compelling candidate landing site for the future Mars 2020 and ExoMars rover missions as it was positioned at the edge of an open basin, could have been an ideal environment for biosignature formation, concentratio...
متن کاملStratigraphy of the Hydrogen Distribution at Equatorial Latitudes on Mars
Neutron data from Mars Odyssey allow the determination of hydrogen stratigraphy in the framework of a simple 2-layer model, for latitudes equatorward of ±50°. On average, hydrogen is buried under a desiccated layer of thickness ~10 g/cm and a water-equivalent hydrogen (WEH) mass fraction in the 1% to 5% range. True hydrogen content of the Martian regolith below this relatively desiccated layer ...
متن کاملSequence Stratigraphy
Sequence stratigraphy is the study of sediments and sedimentary rocks in terms of repetitively arranged facies and associated stratal geometry (Vail 1987; Van Wagoner et al 1988, 1990; Christie-Blick 1991). It is a technique that can be traced back to the work of Sloss et al (1949), Sloss (1950, 1963), and Wheeler (1958) on interregional unconformities of the North American craton, but it becam...
