Little is known about the variation within and among species of long-distance migrants in behavioural strategies and habitat choice on their non-breeding grounds. We report results from regular ringing operations carried out during the winter seasons 2009–2013 and transect counts in 2013, 2015 and 2016 in the Sudan Savanna Zone in Ghana. The best supported capture–mark–recapture model included spe
The 7th International Workshop on Virtual, Augmented, and Mixed Reality for Human-Robot Interaction (VAM-HRI) seeks to bring together researchers from human-robot interaction (HRI), robotics, and mixed reality (MR) to address the challenges related to mixed reality interactions between humans and robots. Key topics include the development of robots capable of interacting with humans in mixed reali
Pseudo-random functions are a fundamental building block in many cryptographic applications. In certain scenarios, a weaker notion (where security is restricted to uniformly random input), but more computationally efficient, called weak pseudo-random functions, is sufficient. In this work, we present new differential attacks on the main binary weak pseudo-random function constructions, namely the
In this paper, we discuss research problems for enabling content distribution and supporting real-time interpersonal communication services (e.g. voice and video) over best effort networks with sufficient quality. We take a practical view of content distribution and quality, and this is the reason for the term “sufficient”. We argue that the understanding of quality as perceived by the user is a k
Joint wheel-slip and vehicle-motion estimation is considered, based on measurements from wheel encoders, an inertial measurement unit, and a global positioning system (GPS). The proposed strategy effectively employs the Rao-Blackwellized particle-filtering framework using a kinematic model. Key vari- ables in active safety systems, such as longitudinal velocity, roll angle, and wheel slip for all

Methylation of the cytosine bases in CpG dinucleotides of DNA is important in many cellular functions including gene regulation, chromosome inactivation, as well as in cancer and other diseases. In this report we investigate the structural effects of methylation of cytosines in CpG sites. Hereditary diseases are frequently caused by mutations in CpG dinucleotides. Aqueous solution molecular dynami
The performance of three different backpack-mounted γ-radiation survey systems has been investigated. The systems are based on a LaBr3:Ce detector and a NaI(Tl) detector both with active volume dimensions of 76.2 mm in diameter and 76.2 mm length and a 123% relative efficiency HPGe detector. The detection limits of the systems were tested in a controlled outdoor environment in Sweden, followed by
Popular Abstract in Swedish Esofagektomi (kirurgiskt avlägsnande av matstrupen) är ett omfattande ingrepp som främst utförs pga cancer, men som även utförs vid vissa godartade sjukdomar. Matstrupen sträcker sig från svalget, via bakre delen av bröstkorgen ned till övre delen av buken. Det anatomiska läget gör att man ur kirurgisk synpunkt oftast måste avlägsna matstrupen via en kombination av inciIn a prospective randomised study following oesophagectomy and gastric tube reconstruction patients with hand-sutured neck anastomoses were compared with patients with circular stapled chest anastomoses. The two groups had equal rates of anastomotic or conduit leaks of 7.3 % (3/41) and 7.1 % (3/42) and of benign anastomotic strictures of 19.5 % (8/41) and 28.6 % (12/42). Another prospective random
We have estimated the activation energy for aromatic oxidation by compound I in cytochrome P450 for a diverse set of 17 substrates using state-of-the-art density functional theory (B3LYP) with large basis sets. The activation energies vary from 60 to 87 kJ/mol. We then test if these results can be reproduced by computationally less demanding methods. The best methods (a B3LYP calculation of the ac
The ability to design and tailor-make antibodies to meet the biophysical demands required by the vast range of current and future antibody-based applications within biotechnology and biomedicine will be essential. In this proof-of-concept study, we have for the first time tailored human recombinant scFv antibodies for site-specific photocoupling through the use of an unnatural amino acid (UAA) and
Equipment installation at MAX IV, a state-of-the-art particle accelerator in Sweden, requires accuracy and precision in the range of micrometers. The measurement technology used is laser tracking, with which the position of a movable reflector is determined, by reflecting the laser beam emitted from a stationary tracker. Data describing the real-time position of the reflector is handled in a softw
I had the opportunity to work with the flood plain community: Nossa Senhora das Gracas in the Amazon in Brazil. During a month long stay I observed the daily life of the people. A life where the inhabitants shape their daily routines after the rising and dropping Solemoes river. Solemoes is a part of the Amazon river. I identified a need of harvesting water during the low water season, when the r
This work proposes methodologies using a model-based approach to gain knowledge on and assist the development of an ion-exchange step in a protein purification process; the separation of IgG from a mixture containing IgG, insulin and transferrin. This approach is suitable for capture and intermediate steps in a process. Both methods involve four consecutive steps. Firstly, the retention of the dif
The advancement of mobile technologies and their ability to utilize the Global Positioning System (GPS) to accurately locate their substantial number of users, prompt Location-Based Services (LBS) significantly.

Ferrochelatase is the terminal enzyme in haem biosynthesis, i.e. the enzyme that inserts a ferrous ion into the porphyrin ring. Suggested reaction mechanisms for this enzyme involve a distortion of the porphyrin ring when it is bound to the enzyme. We have examined the energetics of such distortions using various theoretical calculations. With the density functional B3LYP method we calculate how m
For triangles with linear vertex motion, common practice is to backface cull a triangle if it is backfacing at both the start and end of the motion. However, this is not conservative. We derive conservative tests that guarantee that a moving triangle is backfacing over an entire time interval and over the area of a lens. In addition, we present tests for the special cases of only motion blur and o
In multipath routing, maximization of the cardinality K of the disjoint-path set for a given source and destination assuming an upper bound on the differential delay D is one of the key factors enabling its practical applications. In the paper we study such an optimization problem for multipath routing involving maximization of K under the D constraint as the primary objective, and then minimizati
