Abstract:
In 2014, the discovery of seafloor mounds leaking methane gas into the water column
in the northwestern Barents Sea became the first to document the existence of non-permafrost related gas hydrate pingos (GHP) on the Eurasian Arctic shelf. The discovered site is given attention because the gas hydrates occur close to the upper limit of the gas hydrate stability, thus may be vulnerable to climatic forcing. In addition, this site lies on the regional Hornsund Fault Zone marking a transition between the oceanic and continental crust. The Hornsund Fault Zone is known to coincide with an extensive seafloor gas seepage area; however, until now lack of seismic data prevented connecting deep structural elements to shallow seepages. Here we use high-resolution P-Cable 3D seismic data to study the subsurface architecture of GHPs and underlying glacial and pre-glacial deposits. The data show gas hydrates, authigenic carbonates and free gas within the GHPs on top of gas chimneys piercing a thin section of low-permeability glacial-sediments. The chimneys connect to faults within the underlying tilted and folded fluid and gas hydrate bearing sedimentary rocks. Correlation of our data with regional 2D seismic surveys shows a spatial connection between the shallow subsurface fluid flow system and the deep-seated regional fault zone. We suggest that fault-controlled Paleocene hydrocarbon reservoirs inject methane into the low-permeability glacial deposits and near-seabed sediments, forming the GHPs. This conceptual model explains the existence of climate sensitive gas hydrate inventories and extensive seabed methane release observed along the Svalbard-Barents Sea margin

A Replication Scheme for Multiple Fragmentations with Overlapping Fragments
No full textIn this article, we introduce a replication procedure in a distributed database system that supports several fragmentations of the same data table. One application that requires multiple fragmentations is flexible (similarity-based) query answering. The major feature of our replication procedure is that replication and recovery respect the overlaps of fragments stemming from different fragmentations. In this paper we extend the data replication problem by not only considering hard constraints to ensure a fixed replication factor but also adding soft constraints that express desired data locality of fragments. We furthermore analyze the case that there are more fragmentations (leading to the situation that some replication conditions are optional); and we study the influences of data updates (insertions and deletions) on the data distribution.German Research Foundation [WI 4086/2-1
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe 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
Statische und dynamische Charakterisierung einer Planck-Waage
No full textInhalt dieser Arbeit sind Untersuchungen zu den statischen und insbesondere dynamischen Eigenschaften von Wägesystemen nach dem Prinzip der elektromagnetischen Kraftkompensation (EMK). Für diesen Waagentyp ergeben sich aufgrund der im Jahr 2019 erfolgten Neudefinition des Kilogramm neue Anwendungsfelder, in denen die Definition in Form einer Kibble-Waage direkt in einem Kraftmess- oder Wägesystem umgesetzt wird. Eine derartige Entwicklung, die als Tischgerät konzipiert ist und daher auch als ”table top Kibble Balance” bezeichnet werden kann, stellt die Planck-Waage dar, die in einem gemeinsamen Forschungsprojekt der Physikalisch-Technischen Bundesanstalt (PTB) und dem Institut für Prozessmess- und Sensortechnik (IPMS) der TU Ilmenau auf Basis von kommerziellen EMK-Wägezellen umgesetzt wurde. Aufgrund der prinzipbedingten dynamischen Anregung der Wägezelle und der Notwendigkeit einer rückführbaren Messung der beteiligten elektrischen Größen ergeben sich neuartige Fragestellungen bei der Charakterisierung und metrologischen Bewertung von EMK-Wägezellen. Einen signifikanten Einfluss auf die erreichbare Unsicherheit haben Winkelschwingungen bei der dynamischen Anregung so wie die relative Ausrichtung der Messachsen der Waage zu derjenigen des verwendeten Interferometers. Aufbauend auf Erfahrungen aus Untersuchungen an dynamischen EMK-Wägesystemen werden die Eigenschaften der sogenannten PB2-Variante der Planck-Waage untersucht und deren Auswirkungen auf die Unsicherheit der Massebestimmung analysiert. Dazu kommen verschiedene optische und elektrische Messsysteme zum Einsatz, deren Unsicherheitsbeiträge wiederum selbst berücksichtigt werden. Weiterhin wird ein Messablauf vorgestellt, der die Korrektion von Drifteffekten und die Minimierung des Spulenstromeffekts ermöglicht. Nach dem derzeitigen Stand können mit dem PB2-System Massebestimmungen mit einer relativen Unsicherheit von bis zu 2,5 × 10^-6 in einem Messbereich von 1 mg bis 100 g erreicht werden. Aus den durchgeführten Untersuchungen können jedoch Ansatzpunkte abgeleitet werden, die eine weitere Reduzierung der Unsicherheiten in folgenden Entwicklungen der Planck-Waage ermöglichen.This work presents investigations on the static and especially dynamic properties of weighing systems using the principle of electromagnetic force compensation (EMFC). This type of balances can be used in new fields of applications that directly utilize the redefinition of the Kilogram, which is valid since the year 2019, in weighing or force measurement instruments. The Planck-Balance, which is a table top realization of the principle of a Kibble balance, is such an instrument based on a commercial EMFC load cell and was developed in a joint research project of the Physikalisch-Technische Bundesanstalt (PTB) and the Institute of Process Measurement and Sensor Technology of TU Ilmenau. Due to dynamic excitation, which is necessary because of the working principle, and the necessity of traceable measurements of the involved electrical quantities, new questions arise that relate to the identification of the dynamic and metrological characteristics of EMFC load cells. For instance, tilt oscillations during the dynamic excitation and the misalignment of the measurement axis of the load cell and the used interferometer are identified to have a significant influence on the achievable measurement uncertainties. Based on the experience in the investigation of dynamic EMFC load cells, the properties and their influence on the uncertainty of the mass determination process with the PB2 variant of the Planck-Balance are analyzed. For this purpose, several optical and electrical measurement systems are incorporated, whose contributions to the measurement uncertainty are evaluated. Furthermore, a measurement scheme is presented that allows the correction of drift phenomena as well as minimization of the coil current effect. With the current PB2 system, mass determinations in a measurement range of 1 mg to 100 g were demonstrated that can be done with a relative measurement uncertainty of up to 2.5 × 10−6. However, improved design characteristics can be derived from the presented investigations that allow a further reduction of the uncertainties in ongoing developments of the Planck-Balance
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
Appropriate Similarity Measures for Author Cocitation Analysis
No full textWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
