Measurements of pCO2 and turbulence from an autonomous drifting buoy in 2019 during FALKOR cruise FK191120
No full textData from autonomous, drifting buoy with a floating chamber to measure insitu air-sea carbon dioxide (CO2) fluxes during RV Falkor cruise FK191120 in the southern Pacific during November-December 2019. The technique is described in detail in Ribas-Ribas et al. (2018) (https://doi.org/10.1525/elementa.275). The buoy is equipped with a sensor to measure aqueous and atmospheric partial pressure of CO2 (pCO2), and to monitor the increase or loss of CO2 inside the chamber. One complete cycle including two chamber measurements last 70 minutes. The buoy can be deployed for more than 15 hours, and at wind speeds of up to 10 m/s. Floating chambers are known to overestimate fluxes due to the creation of additional turbulence at the water surface. We check that by measuring turbulence with two Acoustic Doppler Velocimeter (ADV), one directly underneath the center of the floating chamber (equipped with an inertial motion unit) and the other one positioned sideways to measure turbulence outside the perimeter of the buoy

On the Hardness of Generalized Domination Problems Parameterized by Mim-Width
No full textFor nonempty σ, ρ ⊆ ℕ, a vertex set S in a graph G is a (σ, ρ)-dominating set if for all v ∈ S, |N(v) ∩ S| ∈ σ, and for all v ∈ V(G) ⧵ S, |N(v) ∩ S| ∈ ρ. The Min/Max (σ,ρ)-Dominating Set problems ask, given a graph G and an integer k, whether G contains a (σ, ρ)-dominating set of size at most k and at least k, respectively. This framework captures many well-studied graph problems related to independence and domination. Bui-Xuan, Telle, and Vatshelle [TCS 2013] showed that for finite or co-finite σ and ρ, the Min/Max (σ,ρ)-Dominating Set problems are solvable in XP time parameterized by the mim-width of a given branch decomposition of the input graph. In this work we consider the parameterized complexity of these problems and obtain the following: For minimization problems, we complete several scattered W[1]-hardness results in the literature to a full dichotomoy into polynomial-time solvable and W[1]-hard cases, and for maximization problems we obtain the same result under the additional restriction that σ and ρ are finite sets. All W[1]-hard cases hold assuming that a linear branch decomposition of bounded mim-width is given, and with the solution size being an additional part of the parameter. Furthermore, for all W[1]-hard cases we also rule out f(w)n^o(w/log w)-time algorithms assuming the Exponential Time Hypothesis, where f is any computable function, n is the number of vertices and w the mim-width of the given linear branch decomposition of the input graph

Yield performance in heritage spring wheat and barley varieties in organic farming
No full textField trials show that under organic conditions, heritage spring cereals can in some cases give a yield and quality compared with modern varieties. The paper discuss the season for the lack of yield improvement under organic conditions due to plant breeding
Variations on the Author
No full text“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

Mercado interno versus mercado colonial en la primera industrialización española
No full textEditada en Fundación Empresa PúblicaLa intención de este ensayo es analizar el papel del mercado hispanoamericano en
el desarrollo de la industria española durante la segunda mitad del siglo XVIII. En especial,
se discute la visión tradicional que enfatiza la importancia del comercio colonial
en el desarrollo de la industria algodonera moderna en Cataluña. Con el apoyo de investigaciones
recientes se concluye que el mercado interior actuó de motor de arranque
de la industrialización española.The aim of this essay is to analize the role of the Spanish American colonial market
in the development of the Spanish industry during the second half of the XVIIIth century.
Specially we discuss the traditional view wich emphasizes the importance of the
colonial trade for the development of the modem cotton industry in Catalonia. With
the support of new evidence fumished by recent research we conclude that the internal
market was the engine of the Spanish industrialization.Publicad
