Earthquake catalogs for: A specific earthquake processing workflow for studying long-lived explosive volcanic eruptions with application to the 2008 Okmok eruption
No full textRepository for the seismic catalogs from Garza-Giron et al. (submitted). These include the catalog with absolute locations using NonLinLoc (Lomax et al., 2001; Lomax and Curtis, 2001), and the relocated catalogs using hypoDD (Waldhauser and Ellsworth, 2000) and GrowClust (Trugman and Shearer, 2017).
The header of the CSV files is as follows:
Date (year/month/day), Time (hr:min:sec:msec), Latitude (decimal degrees), Longitude (decimal degrees), Depth (km), Magnitude (Ml calculated for this study), Event_type (VT:vulcano-tectonic;LP:long-period), Number of stations where the event was detected, ID

We are grateful to the staff of the Alaska Volcano Observatory for their heroic work in collecting the key data of this paper and their insightful feedback throughout this project. We are also grateful to Heather Crume (Shaddox) who provided thoughtful suggestions for the writing of this manuscript and to the participants of the UCSC Seismo Lab coffee hours for discussion of this work. This work was partially supported by the Mexican National Council for Science and Technology (CONACYT) Doctoral Scholarship to Garza-Giron and in part by NSF EAR-2102069. The maps shown in this work were made using The Generic Mapping Tools (GMT)(Wessel et al., 2019). The majority of the seismological signal processing performed in this work was done using the Obspy Python package (Beyreuther et al., 2010). For the quality control process of this work we made use of the Pyrocko library (Heimann et al., 2019) and the Kurtosis picker from the PhasePApy package (Chen and Holland, 2016).

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
Opening wedge high tibial osteotomy using a monoaxial dynamic external fixator
No full textPurpose: To prospectively assess midterm results in 37 patients (41 knees) who were treated with opening wedge high tibial osteotomy (OW-HTO) with the use of a monoaxial dynamic external fixator (MDEF) for medial knee osteoarthritis. Methods: Clinical and subjective evaluations were performed using the IKDC and KOOS evaluation forms and the modified Knee Society Clinical Rating System (KSS). Pin tract infections were evaluated according to Checketts–Otterburns classification. Radiographic evaluation included long-standing AP lower limb, standard lateral, Rosenberg and Merchant views. Results: Thirty-six patients (40 knees) were evaluated at a mean follow-up period of 7 years. Ten patients (25 %) developed a minor pin tract infection. Subjective KOOS and IKDC scores showed statistically significant improvement. Clinical evaluation with IKDC and KSS forms showed no patient with instability or a range-of-motion deficit worst than pre-operatively. At MDEF removal, the mechanical axis was on average 4.5° valgus; anatomical axis 6.8° valgus; the Mikulicz’ line crossed the tibial plateau on average at 64 % of the width of the tibial plateau measured from medial; the posterior slope 5°; the metaphyseal varus 4.3°; and the Insall/Salvati ratio 1.02. At latest follow-up, five patients had a loss of correction of 1°–2° on mechanical axis and one patient had a loss of correction of 3° on mechanical axis and 4 % of mechanical axis on tibial plateau. Conclusions: The use of a MDEF to perform an OW-HTO showed a good maintenance of correction achieved with satisfactory midterm outcome results in all patients but three who underwent total knee replacement. The only severe post-operative complication was one case of non-union in a heavy smoker. Level of evidence: Prospective and therapeutic study, Level IV
Energetic behavior of mithocondria isolated from rat livers perfused with a perfluorodecalin + N,N-perfluorodiethylcyclohexylamine emulsion
No full textRat livers have been perfused with a saline control medium or with a perfluorocarbon emulsion containing perfluorodecalin and N,N-perfluordiethylciclohexylamine, and the respiratory rates and transmembrane electrical potentials of mitochondria isolated following perfusion have been evaluated. The results indicate that the perfluorocarbon emulsion used, by providing a good oxygen supply to the perfused liver, allowed to preserve the efficiency of mitochondrial oxidative phosphorylation
