First-time migration in juvenile common cuckoos documented by satellite tracking
Being an obligate parasite, juvenile common cuckoos Cuculus canorus are thought to reach their African wintering grounds from Palearctic breeding grounds without guidance from experienced conspecifics but this has not been documented. We used satellite tracking to study naïve migrating common cuckoos. Juvenile cuckoos left breeding sites in Finland moving slowly and less consistently directed than
Visual Entity Linking: A Preliminary Study
In this paper, we describe a system that jointly extracts entities appearing in images and mentioned in their ac- companying captions. As input, the entity linking pro- gram takes a segmented image together with its cap- tion. It consists of a sequence of processing steps: part- of-speech tagging, dependency parsing, and coreference resolution that enables us to identify the entities as well as po
Influence of the choice of projection manifolds in the CASPT2 implementation
The Complete Active Space Second-Order Perturbation Theory (CASPT2) is well-established as a high-accuracy electronic structure method. It was originally implemented in the early 1990s to an efficient computer code in the molcas program suite, and this implementation has been extensively used as a standard tool. Here, we report a comparison of it against two independent computer-aided implementati
Loss mapping of an Insert Permanent Magnets Synchronous Machine for parallel hybrid electric heavy vehicles
This paper focuses on mapping the different losses present in an Insert Permanent Magnet Synchronous Machine (IPMSM). The machine is designed as a traction machine according to the requirements of a parallel hybrid electric heavy vehicle. This includes a wide constant power range and overload capability, all to be fitted in a strictly limited space in the vehicle. In order to meet the requirements
Direct electromagnetic actuation on high ratio gears
This document demonstrates a conceptual study, design and development of unconventional electromagnetic actuators for applications where a high torque over a limited part of a rotational turn is required. The unconventionality of the actuators is that the electromagnetic actuation is applied directly on a high ratio transmission gear such as a cycloid disc in a cycloid drive or a flex-spline in a
Linking, Searching, and Visualizing Entities for the Swedish Wikipedia
In this paper, we describe a new system to extract, index, search, and visualize entities on Wikipedia. To carry out the extraction, we designed a high-performance entity linker and we used a document model to store the resulting linguistic annotations. The entity linker ,HERD, extracts the mentions from text using a string matching Engine and links the mto entities with a combination of rules, Pa
The HIF-2alpha-Driven Pseudo-Hypoxic Phenotype in Tumor Aggressiveness, Differentiation, and Vascularization.
Cellular adaptation to diminished tissue oxygen tensions, hypoxia, is largely governed by the hypoxia inducible transcription factors, HIF-1 and HIF-2. Tumor hypoxia and high HIF protein levels are frequently associated with aggressive disease. In recent years, high tumor cell levels of HIF-2 and the oxygen sensitive subunit HIF-2alpha have been associated with unfavorable disease and shown to be
Enclosures in West Pokot, Kenya : Transforming land, livestock and livelihoods in drylands
Dryland livestock production systems are changing in many parts of the world, as a result of growing human populations and associated pressure on water and land. Based on a combination of social and natural science methods, we studied a 30-year transformation process from pastoralism to a livestock-based agro-pastoral system in northwestern Kenya, with the overall aim to increase the understanding

A Soft-Output MIMO Detector with Achievable Information Rate based Partial Marginalization
In this paper, we propose a soft-output detector for multiple-input multiple-output (MIMO) channels that utilizes achievable information rate (AIR) based partial marginalization (PM). The proposed AIR based PM (AIR-PM) detector has superior performance compared to previously proposed PM designs and other soft-output detectors such as K-best, while at the same time yielding lower computational comp
Three-dimensional experimental granular mechanics
Results are presented from a new method for experimental analysis of the mechanics of real granular materials in three dimensions. The method involves a combination of X-ray tomography and three- dimensional (3D) X-ray diffraction to provide the grain-scale structural evolution (grain positions and kinematics, grain-contact distributions and grain-grain contact fracture) simultaneously with the te
Influence of potassium and iron chloride on the early stages of soot formation studied using imaging LII/ELS and TEM techniques
Laser-induced incandescence (LII), elastic light scattering (ELS) and extinction were used to investigate the early stages of soot formation when seeding metal salts at various concentrations into a premixed ethylene/air flame on a PerkinElmer burner. The investigation contained seven salts, where we in this work mainly focus on two of these salts, potassium chloride (KCl) and iron chloride (FeCl3
Bat Activity at a Small Wind Turbine in the Baltic Sea
Activity of bats at an old wind park four km off the island of Gotland in the Baltic Sea was monitored during 50 nights from August to October 2013, using an automatic bat detector (Pettersson D500-X) mounted on one of the turbines. Single individuals or pairs of common noctules Nyctalus noctula were recorded on five occasions only (26 and 27 August), all in calm weather and when little or no roto
Stödtjänster för hantering av forskningsdata – möjligheter för forskningsbiblioteken
I denna artikel beskriver vi verksamheten inom hantering av forskningsdata på Avdelningen för Vetenskaplig kommunikation vid Universitetsbiblioteket i Lund sedan den startade 2014. Huvuddelen av våra projekt har hittills varit av karaktären utredningar och behovsanalyser på grund av att det saknas policyer eller riktlinjer för forskare såväl nationellt som på lärosätet. Däremot finns förväntningar
Quantitative picosecond laser-induced fluorescence measurements of nitric oxide in flames
Quantitative concentrations measurements using time-resolved laser-induced fluorescence have been demonstrated for nitric oxide (NO) in flame. Fluorescence lifetimes measured using a picosecond Nd:YAG laser and optical parametric amplifier system have been used to directly compensate the measured signal for collisional quenching and evaluate NO concentration. The full evaluation also includes the
Mid-infrared laser-induced thermal grating spectroscopy in flames
For the first time, laser-induced thermal grating spectroscopy (LITGS) in the spectral range around 3. μm is demonstrated as a versatile diagnostic tool. This spectral region is of particular interest in combustion diagnostics as many relevant species such as hydrocarbons and water exhibit fundamental vibrational modes and hence can be probed with high sensitivity. Another benefit of the IR-LITGS
Modeling of alkali metal release during biomass pyrolysis
The release of alkali metals (Na and K) during biomass pyrolysis was numerically and experimentally investigated using Laser-Induced Breakdown Spectroscopy technique that could extend the measurements of alkali metal concentration to the sooty pyrolysis stage. Two distinct peaks of metal concentrations were observed at the pyrolysis stage and at the gasification stage. Since during the pyrolysis s
Rate-ratio asymptotic analysis of the influence of stoichiometric mixture fraction on structure and extinction of laminar, nonpremixed methane flames with comparison to experiments
Activation energy asymptotic analysis and rate-ratio asymptotic analysis of combustion in laminar, nonpremixed flames are often carried out using conserved scalar quantities as independent variables. One such representation of a conserved scalar quantity is the mixture fraction, ξ, based on thermal diffusivity. These analyses are carried out in the asymptotic limit of large Damköhler number, with
Influence of ice accretion on the noise generated by an airfoil section
We investigate the noise generated by an airfoil section. Three cases are considered, one with a clean airfoil and two cases with airfoils with ice accretion. The amount of ice is the same in the two cases with ice accretion, but the surface of the accreted ice layer is smoother in one of them. The noise is computed using a hybrid approach. First the flow and the acoustic sources are computed. Sec
