NOx surface observation data
No full textDaily average NO2 concentrations for selected Chinese cities during the coronavirus disease 2019 (COVID-19) lockdown. Observations were obtained from the China National Environmental Monitoring Center. Original CMAQ model predictions were based on the 2017 Multiresolution Emission Inventory of China (MEIC). Optimized predictions were from a second CMAQ run using adjusted sectoral emissions of NO2 as described in the manuscript
Numerical model of multi-phase porous, mush, and suspension flows in magmatic systems
No full textMagmatic systems in the Earth's mantle and crust can range from melt-poor partially molten rock to trans-crustal magma mushes with ephemeral lenses of melt-rich suspensions. Most process-based models of magmatic systems, however, are limited to two-phase porous flow at low melt fractions (<20%) or suspension flow at high melt fractions (>60%). A lack of formal extensions to intermediate phase fractions has long hindered investigations into the dynamics of mush flows. To address this knowledge gap and unify two-phase magma flow models, we present a two-dimensional system-scale numerical model of the fluid mechanics of an n-phase system valid at all phase fractions. The numerical implementation uses a finite-difference staggered-grid approach with a dampened pseudo-transient iterative algorithm and is verified using the Method of Manufactured Solutions. Numerical experiments replicate known limits of two-phase flow including rank-ordered porosity wave trains in 1D and porosity wave breakup in 2D in the porous flow regime, as well as particle concentration waves in 1D and mixture convection in 2D in the suspension flow regime. In the mush regime, numerical experiments show strong liquid localisation into pockets and stress-aligned bands. A tentative application to a three-phase, solid-liquid-vapour system demonstrates the broad utility of the n-phase general model and its numerical implementation. The model code is available open source at github.com/kellertobs/pantarhei

Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
