Acid weathering of basalt and basaltic glass: 2. Effects of microscopic alteration textures on spectral properties
(Journal of Geophysical Research: Planets, 2017-01-24)Acid alteration has long been proposed for the Martian surface, and so it is important to understand how the resulting alteration textures affect surface spectra. Two basaltic materials of varying crystallinity were altered ... -
Evolution of Occator Crater on (1) Ceres
(The Astronomical Journal, 2017-02-17)The dwarf planet Ceres (diameter 939 km) is the largest object in the main asteroid belt. Recent investigations suggest that Ceres is a thermally evolved, volatile-rich body with potential geological activity, a body which ... -
Submicroscopic metallic iron in lunar soils estimated from the in situ spectra of the Chang’E-3 mission
(Geophysical Research Letters, 2017-04-22)Submicroscopic metallic iron (SMFe) created by space weathering has strong effects on the optical properties of the lunar surface. Spectra measured in situ by the visible-near-infrared spectrometer (VNIS) on board the ... -
Oxo Crater on (1) Ceres: Geological History and the Role of Water-ice
(The Astronomical Journal, 2017-08-04)Dwarf planet Ceres (∅ ∼ 940 km) is the largest object in the main asteroid belt. Investigations suggest that Ceres is a thermally evolved, volatile-rich body with potential geological activity, a body that was never ... -
Visible/near-infrared spectral diversity from in situ observations of the Bagnold Dune Field sands in Gale Crater, Mars
(Journal of Geophysical Research: Planets, 2017-12-13)As part of the Bagnold Dune campaign conducted by Mars Science Laboratory rover Curiosity, visible/near-infrared reflectance spectra of dune sands were acquired using Mast Camera (Mastcam) multispectral imaging (445–1013 ... -
Least Periods of Factors of Infinite Words
(EDP Sciences, 2009)We show that any positive integer is the least period of a factor of the Thue-Morse word. We also characterize the set of least periods of factors of a Sturmian word. In particular, the corresponding set for the Fibonacci ... -
Dejean's conjecture holds for n ≥ 27
(EDP Sciences, 2009)We show that Dejean’s conjecture holds for n ≥ 27. This brings the final resolution of the conjecture by the approach of Moulin Ollagnier within range of the computationally feasible. -
Infinite words containing squares at every position
(EDP Sciences, 2010)Richomme asked the following question: what is the infimum of the real numbers α > 2 such that there exists an infinite word that avoids α-powers but contains arbitrarily large squares beginning at every position? We resolve ... -
Sparks of Light: Survivor Narratives Reflected Through the Lens of Irving Greenberg’s Theology
(University of WinnipegUniversity of Winnipeg, 2018-01-22)In the future, when no first-person witnesses to the Shoah are left to tell their stories, we will be left with their written, audio, and video narratives. Those who will be left to bear witness for them can tell their ... -

Craniometric analysis of European Upper Palaeolithic and Mesolithic samples supports discontinuity at the Last Glacial Maximum
(Macmillan Publishers Limited, 2014-06-10)The Last Glacial Maximum (LGM) represents the most significant climatic event since the emergence of anatomically modern humans (AMH). In Europe, the LGM may have played a role in changing morphological features as a ... -
