A new sedimentary and biostratigraphic framework for the Callovian-Oxfordian transition on the Atlantic margin of Morocco

Duval-Arnould, Aude (author), Bulot, Luc (author), Masrour, Moussa (author), Simmons, Mike (author), Bonnot, Alain (author), Charton, R.J.G. (author), Redfern, Jonathan (author), Schröder, Stefan (author)

A major global marine transgression occurred during the Callovian to Early Kimmeridgian, which was interrupted locally by a hiatus during the Late Callovian to Early Oxfordian. The transgression may have been a major driver for extensive coral buildup development in the Oxfordian. The depositional hiatus may be related to a combination of...

Effect of porosity on Curle's dipolar sources on an aerofoil in turbulent flow

Zamponi, R. (author), Satcunanathan, S. (author), Moreau, S. (author), Meinke, M. (author), Schröder, W. (author), Schram, C. (author)

Integrating a porous material into the structure of an aerofoil constitutes a promising passive strategy for mitigating the noise from turbulence–body interactions that has been extensively explored in the past few decades. When a compact permeable body is considered in the aeroacoustic analogy derived by Curle to predict this noise source, a...

Resource-efficient fault-tolerant one-way quantum repeater with code concatenation

Wo, Kah Jen (author), Avis, G. (author), Rozpędek, Filip (author), Mor-Ruiz, Maria Flors (author), Pieplow, Gregor (author), Schröder, Tim (author), Jiang, Liang (author), Sørensen, Anders S. (author), Borregaard, J. (author)

One-way quantum repeaters where loss and operational errors are counteracted by quantum error-correcting codes can ensure fast and reliable qubit transmission in quantum networks. It is crucial that the resource requirements of such repeaters, for example, the number of qubits per repeater node and the complexity of the quantum error...

Comparison of arterial wall models in fluid–structure interaction simulations

Balzani, D. (author), Heinlein, A. (author), Klawonn, A. (author), Rheinbach, O. (author), Schröder, J. (author)

Monolithic fluid–structure interaction (FSI) of blood flow with arterial walls is considered, making use of sophisticated nonlinear wall models. These incorporate the effects of almost incompressibility as well as of the anisotropy caused by embedded collagen fibers. In the literature, relatively simple structural models such as Neo-Hooke are...

Identifying local vs. regional drainage using multiproxy provenance tracers: Tracking the Moroccan Late Triassic fluvial system

Lovell-Kennedy, James (author), Roquette, Emmanuel (author), Schröder, Stefan (author), Charton, R.J.G. (author), Redfern, Jonathan (author)

The Kerrouchen Basin is an understudied rift basin in the Middle Atlas of Morocco, where over 600 m of Triassic stratigraphy is well exposed. It was partially inverted during the Atlasic orogeny whilst preserving the original basin geometry. Within the Kerrouchen Basin, two distinct fluvial systems are present. The first, recorded by the K3...

The contribution of trade to production-Based carbon dioxide emissions

Wu, Ran (author), Ma, Tao (author), Schröder, E. (author)

International trade and emission offshoring can reduce a country's domestic carbon dioxide emissions, helping it to reach emission reduction targets set under the prevailing territorial climate policy frameworks. We ask what is the net contribution of trade to national production-based emissions. Existing metrics (consumption-based emissions and...

On the Interpretation and Measurement of Technology-Adjusted Emissions Embodied in Trade

Darwili, A.G. (author), Schröder, E. (author)

We propose a new method for standardizing the production technology at the world average level and derive interpretations for the resulting carbon emission concepts. The technology-adjusted emission balance measures net weak carbon leakage defined as the difference between the foreign emissions avoided by exports and the foreign emissions...

Environmental influences on the stability of a permanently installed laser scanner

Kuschnerus, M. (author), Schröder, D. (author), Lindenbergh, R.C. (author)

The advancement of permanently measuring laser scanners has opened up a wide range of new applications, but also led to the need for more advanced approaches on error quantification and correction. Time-dependent and systematic error influences may only become visible in data of quasi-permanent measurements. During a scan experiment in...

Early post-rift depositional systems of the Central Atlantic: Lower and Middle Jurassic of the Essaouira-Agadir Basin, Morocco

Duval-Arnould, Aude (author), Schröder, Stefan (author), Charton, R.J.G. (author), Joussiaume, Rémi (author), Razin, Philippe (author), Redfern, Jonathan (author)

Passive margins are traditionally regarded as tectonically quiescent, however the increasing recognition of significant post-rift tectonic uplift along their flanks offers an important control on sediment delivery. The most extensive record of the early post-rift succession of the Central Atlantic Margin (CAM) is found in the Lower and Middle...

Economic Growth and Carbon Emissions: The Road to “Hothouse Earth” is Paved with Good Intentions

Schröder, E. (author), Storm, S.T.H. (author)

De-carbonization to restrict future global warming to 1.5 °C is technically feasible but may impose a “limit” or “planetary boundary” to economic growth, depending on whether or not human society can decouple growth from emissions. In this paper, we assess the viability of decoupling. First, we develop a prognosis of climate-constrained...

One-Way Quantum Repeater Based on Near-Deterministic Photon-Emitter Interfaces

Borregaard, J. (author), Pichler, Hannes (author), Schröder, Tim (author), Lukin, Mikhail D. (author), Lodahl, Peter (author), Sørensen, Anders S. (author)

We propose a novel one-way quantum repeater architecture based on photonic tree-cluster states. Encoding a qubit in a photonic tree cluster protects the information from transmission loss and enables long-range quantum communication through a chain of repeater stations. As opposed to conventional approaches that are limited by the two-way...

Spillover effects of Germany's final demand on Southern Europe

Picek, Oliver (author), Schröder, E. (author)

We use data from the World Input-Output Database to fit a closed multiregional input-output model in order to estimate the size of spillover effects of Germany's final demand on GDP, employment and the trade balance in Southern European countries. We find that spillover effects are rather small. Germany alone will hardly make a significant...

Offshoring, employment, and aggregate demand

Schröder, E. (author)

The article uses a demand-constrained small-open-economy model in the tradition of Keynes and Kalecki to study the effects of offshoring on aggregate demand and domestic employment. Offshoring is represented as labor-saving import-using technical change. The results depend on the behavior of the markup on unit costs. If higher markups absorb...
