The present work describes the numerical modeling of medium-speed marine engines, operating in a fumigated dual-fuel mode, i.e. with the second fuel injected in the ports. This engine technology allows reducing engine-out emissions while maintaining the engine efficiency and can be fairly easily retrofitted from current diesel engines. The main premixed fuel that is added can be a low-carbon one a
The circumpolar Arctic is currently facing multiple global changes that have the potential to alter the capacity of tundra soils to store carbon. Yet, predicting changes in soil carbon is hindered by the fact that multiple factors simultaneously control processes sustaining carbon storage and we do not understand how they act in concert. Here, we investigated the effects of warmer temperatures, en
We present GlassesViewer, open-source software for viewing and analyzing eye-tracking data of the Tobii Pro Glasses 2 head-mounted eye tracker as well as the scene and eye videos and other data streams (pupil size, gyroscope, accelerometer, and TTL input) that this headset can record. The software provides the following functionality written in MATLAB: (1) a graphical interface for navigating the
Background Progressive keratoconus can lead to severely impaired vision, but there is currently no consensus on the definition of progressive disease. Errors in the measurement of the parameters commonly used to establish progressive disease were evaluated in an attempt to determine the limits at which a true change in the values can be detected. The possible association between measurement error
The relative contribution of different microbial groups to soil organic matter (SOM) turnover and utilisation of rhizodeposits during a cropping season has remained largely unknown. We used a long-term field experiment (started in 1956), in which C3 crops were replaced with C4 silage maize in 2000, to investigate dynamics of fungi and bacterial groups and their utilisation of ‘young-C4’ and ‘old-C
BACKGROUND: Transient tachypnea of the newborn (TTN) is characterized by tachypnea and signs of respiratory distress. Transient tachypnea typically appears within the first two hours of life in term and late preterm newborns. Supportive management might be sufficient. Non-invasive (i.e. without endotracheal intubation) respiratory support may, however, be administered to reduce respiratory distres
Echinolittorina malaccana, a marine gastropod living on rocky shores along the Indo-West Pacific coasts, shows consistent mate choice in which males prefer to mate with females slightly larger than themselves. Previous studies suggest that the strength of this preference is, to a certain extent, context dependent, being influenced by both demographic and individual (potentially genetic) factors. T
The ongoing climate change has been increasingly reflected in climate observations around the world, both in terms of averages and extremes, and attributed to anthropogenic climate forcing. When it comes to changing extremes, attribution to climate change is now especially well-established for heat-related extremes worldwide. Understanding changes in extremes is important for climate adaptation as
Multivariate random sums appear in many scientific fields, most notably in actuarial science, where they model both the number of claims and their sizes. Unfortunately, they pose severe inferential problems. For example, their density function is analytically intractable, in the general case, thus preventing likelihood inference. In this paper, we address the problem by the method of moments, unde
In 2009 the conservative Swedish government launched a new cultural policy proposition emphasising broader engagement in the arts both consumption-wise, politically and economically. This proposition and two specific elements of it will be discussed in this paper; the cooperation and consultation model of distribution of state support to regional culture and schemes for stimulating broadened, i.e.
Within a collaboration between MAX-lab and BESSY a one stage seeded HGHG-FEL has been set up at Maxlab. BESSY has built the undulator system consisting of a modulator, a radiator and an electromagnetic chicane. BESSY has also installed three types of diagnostic tools: optical fibres for a fast Cherenkov beam loss detection, optical fibres for absolute dose measurements via their radiation-induced
In this paper we study the propagation problem of a time harmonic electro- magnetic field inside a cavity filled with a generic bianisotropic medium. We define the concepts of eigenfrequencies and modes of the cavity and we prove their existence and countability. We extend, in this respect, the theory for the isotropic, homogeneous, lossless cavity.
