Construction of a genetic linkage map of the laboratory rat, Rattus norvegicus, establishes the rat as a genetic model. Allele sizes were reported for 432 simple sequence length polymorphisms (SSLPs) genotyped in 12 different substrains belonging to nine different inbred strains of rats. However, these nine strains represent only a fraction of the more than 140 inbred strains available. If allele
Novel carboxymethyl cellulose-chitosan (CMC-Cht) hybrid micro- and macroparticles were successfully prepared in aqueous media either by drop-wise addition or via nozzle-spray methods. The systems were either physically or chemically crosslinked using genipin as the reticulation agent. The macroparticles (ca. 2 mm) formed are found to be essentially of the core-shell type, while the microparticles
A controlled experiment was carried out by doing geophysical measurements on a purpose-built heap consisting of two different industrial waste fractions, called NF ( non-ferrous metal) and SLF (shredder light fraction), from the recycling plant of Stena Metall in Halmstad, Sweden. The purpose of the experiment was to see if it was possible to distinguish the different types of material using geoph
Rapid technical advances in the field of computer animation (CA) and virtual reality (VR) have opened new avenues in animal behavior research. Animated stimuli are powerful tools as they offer standardization, repeatability, and complete control over the stimulus presented, thereby "reducing" and "replacing" the animals used, and "refining" the experimental design in line with the 3Rs. However, ap
We present a novel family of deep neural architectures, named partially exchangeable networks (PENs) that leverage probabilistic symmetries. By design, PENs are invariant to block-switch transformations, which characterize the partial exchangeability properties of conditionally Markovian processes. Moreover, we show that any block-switch invariant function has a PEN-like representation. The DeepSe
Familial clustering of a disease is a direct indicator of a possible heritable cause, provided that environmental sharing can be excluded. If the familial clustering is lacking, the likelihood of a heritable influence is also small. In the era of genome scans, the consideration of data on heritability should be important in the assessment of the likely success of the genome scan. The availability
AIMS: The main objective was to determine premature stroke risk in men and women in Sweden with previous hospital admission for Type 1 diabetes or without previous hospital admission.METHODS: All individuals in Sweden aged 15-34 years at first hospital admission for Type 1 diabetes and aged 15-49 years at first hospital admission for stroke during the study period (1987-2001) were identified. Stan
N-body simulations sample their initial conditions on an initial particle distribution, which for cosmological simulations is usually a glass or grid, while a Poisson distribution is used for galaxy models, spherical collapse, etc. These pre-initial conditions have inherent correlations, noise due to discreteness, and preferential alignments, while the glass distribution is poorly defined and comp
Molecular motor-based nanodevices require organized cytoskeletal filament guiding along motility-promoting tracks, confined by motility-inhibiting walls. One way to enhance motility quality on the tracks, particularly in terms of filament velocity but also the fraction of motile filaments, is to optimize the surface hydrophobicity. We have investigated the potential to achieve this for the actin-m
Quantitative evaluations are valuable in the strive for improvements and asserting quality. However, the field of Command & Control (C2) evaluations are hard to navigate, and it is difficult to find the correct measurement for a specific situation. A comprehensive Scoping Study was made concerning measurements of C2 performance and effectiveness. A lack of an existing appropriate framework for

Although there have been significant advances in the research field of critical infrastructures and vital societal functions during the last decade, there still exist many challenges in implementing and carrying out studies in practice. One of these challenges is a feasible method for mapping, analysing and visualising the cascading consequences that arise for critical infrastructures and societal
Current metabarcoding studies aiming to characterize microbial communities generally rely on the amplification and sequencing of relatively short DNA regions. For fungi, the internal transcribed spacer (ITS) region in the ribosomal RNA (rRNA) operon has been accepted as the formal fungal barcode. Despite an increasing number of fungal metabarcoding studies, the amplification efficiency of primers
Abrupt climatic changes have occurred several times in the past, leading to large-scale modifications of vegetation patterns with important consequences for the global carbon cycle. Dynamic global vegetation models (DGVM) constitute an advanced tool for reconstructing past or predicting future shifts in vegetation distributions in response to climatic change on a global scale. The Lund-Potsdam-Jen
Fetal and neonatal alloimmune thrombocytopenia (FNAIT) may result in severe bleeding, particularly fetal and neonatal intracranial haemorrhage (ICH). As a result, FNAIT requires prompt identification and treatment; subsequent pregnancies need close surveillance and management. An international panel convened to develop evidence-based recommendations for diagnosis and management of FNAIT. A rigorou
Ambitionen att minska köttkonsumtionen är lovvärd men riskerar att slå hårt mot den biologiska mångfalden och ekosystemtjänster. Om våra naturbetesmarker försvinner kan vi inte leva upp till FN:s internationella hållbarhetsmål och våra egna svenska miljömål som vi förbundit oss att jobba mot, skriver ett flertal forskare.
OBJECTIVE: The aim of this study was to test the coherence of a wearable device, an inertial measurement unit (IMU) against the gold standard; also, to test the intra-trial reliability. This study has a cross-sectional design, where measurement of postural sway in the medio-lateral and anterior-posterior directions was performed simultaneously on a force plate and with a IMU called the Snubblomete
The aim is to investigate associations between sexual orientation and experience of suicide thoughts and suicide attempts. The 2012 public health survey in Scania, southern Sweden, is a cross-sectional population-based study including 28,029 participants aged 18–80 with 51.7% participation. The associations between sexual orientation and experience of suicide thoughts and attempts were investigate
The shell condenser is a key component for the underwater vehicles. To study its heat transfer performance and flow characteristics and to design a more efficient structure, a mathematical model is generated to simulate condensation inside the straight and helical channels. The model combines empirical correlations and MATLAB based on an it
