Beyond Knower Levels: Early partial knowledge of number words
David Barner, Rok Žaucer, Jessica Sullivan, Tina Razboršek, Vesna Plesničar, Katie Wagner, Franc Marušič, 2015, published scientific conference contribution abstract

Abstract: Although both syntax and number words can indicate quantity, only numbers can specify large exact quantities. Do children use syntax to bootstrap preliminary meanings of number words before mastering precise meanings? We compared errors across languages on a Give-a-Number task in non-knowers (who have adult meanings for no number words) and subset knowers (who have adult meanings for fewer than five number words). Participants included learners of English, Spanish, French, and two dialects of Slovenian. One dialect, Central Slovenian, has rich number morphology including singular, dual, small plural, and large plural (for 5+). In all languages, subset knowers and some non-knowers demonstrated better than random responding for at least 2 number words beyond the largest number word they comprehended precisely. Additionally, Central Slovenian-learning non- and 1- knowers responded more accurately to requests for higher numbers than their counterparts in other languages, suggesting that rich plural marking may bootstrap number word meanings.

Characterization of Mg low-index surfaces by first-principles
Miha Gunde, 2017, master's thesis

Abstract: In this work, three surfaces, namely, Mg(0001), Mg(10 ̄1 0) and Mg(11 ̄2 0) are investigated by means of Density Functional Theory and Generalized Gradient Approximation first-principle calculations. The surfaces have been characterized in terms of their interlayer distances, surface energies, Projected Density of States and Surface Core Level Shifts. Contrary to what was found in previous studies based on Density Functional Theory-Local Density Approximation, the use of Generalized Gradient Approximation exchange correlation functional unravels the oscillatory behavior of both interlayer distances and Surface Core Level Shifts of Mg(10 ̄1 0). Moreover, the Projected Density Of States of un-reconstructed Mg(11 ̄2 0) exhibit the typical quantisation of electronic levels associated to a 2D-confinement of a 3D nearly-free electron gas, as observed in nano-wires, and a Peierls instability along the unconfined direction. Different possible reconstructions on Mg(11 ̄2 0) have then been investigated. In particular, it is found that the surface energy of (2X1) and (3X1) reconstructions is almost degenerate and lower than the surface energy of the unreconstructed Mg(11 ̄2 0) surface. Because of the quasi-degeneracy of surface energies, Mg(11 ̄2 0) surface should be composed by a combination of all the quasi degenerate phases.

Influence of very large spatial heterogeneity on estimates of sea-level trends
M. Shnirman, Vincent Courtillot, Alexander Shapoval, Jean-Louis Le Mouël, 2020, original scientific article

Abstract: We propose a new method to estimate sub-decadal to centennial time scales of sea-level change. Since the coastal data exhibit large spatial heterogeneity and temporal variability, the global sea-level rate is estimated as an appropriate average of the rates observed at available locations and computed with sliding windows. We claim that under such heterogeneity the median serves as a better representative of an adequate average than the mean. With this approach, the sea-level rate in 60 to 70 yr windows over the past century is found to be smaller than 1.7-1.9 mm/yr. These upper estimates are in line with those obtained with a scarce list of available long quasi-gapless series
