The menisci play a critical protective role for the knee joint through shock absorption and load distribution. Asymptomatic meniscal tears are common and are frequent incidental findings on knee MR imaging of the middle-aged or older patient. A meniscal tear can lead to knee osteoarthritis (OA), but knee OA can also lead to a spontaneous meniscal tear through breakdown and weakening of meniscal st
Many insects perceive the E-vector orientation of polarized skylight and use it for compass navigation. In locusts, polarized light is detected by photoreceptors of the dorsal rim area of the eye. Polarized light signals from both eyes are integrated in the central complex (CC), a group of neuropils in the center of the brain. Thirteen types of CC neuron are sensitive to dorsally presented, polari
To assess parents' opinions about their participation in the longitudinal, multicenter study - The Environmental Determinants of Diabetes in the Young (TEDDY) consortium.
Two approaches to moral education are discussed in the article: one aiming at detachment in terms of personal autonomy, one aiming at relatedness in terms of a conscious socialisation into a shared morality of a community. The philosophical features of the two approaches are related to their respective pedagogical implications in a study of the pedagogical guidelines for confirmation work in the c
Background: The Autism Diagnostic Interview-Revised (ADI-R) is considered a first choice assessment tool in autism spectrum disorder. Nevertheless, despite its wide use in psychiatric practice and recommendations by various clinical guidelines, its interrater reliability has predominantly been confirmed in research settings by specially trained, research reliability interviewers. The reliability o
After a long career in studying agricultural and rural development, in the following paper I take the opportunity to reflect on these issues in the rear view mirror. The advantage of this is of course that my biographical time span now covers a considerable historical one, starting with the apocalyptic alarms over the population bomb at the end of the 60s, especially in Asia, and the widespread fe
Silicon isotope ratios (expressed as δ30Si) in marine microfossils can provide insights into silica cycling over geologic time. Here we used δ30Si of sponge spicules and radiolarian tests from the Paleogene Equatorial Transect (Ocean Drilling Program Leg 199) spanning the Eocene and Oligocene (~50-23 Ma) to reconstruct dissolved silica (DSi) concentrations in deep waters and to examine upper ocean
In this paper, we consider a version of the functional Hodrick-Prescott filter for functional time series. We show that the associated optimal smoothing operator preserves the ‘noise-to-signal ratio’ structure. Moreover, as the main result, we propose a consistent estimator of this optimal smoothing operator.
Global comparative studies of the links between economic growth, carbon emissions and ecological footprints as well as social inequality demonstrate that current Western production and consumption patterns and welfare standards are incompatible with environmental limits and IPCC climate targets. To allow for catch-up' development in poorer countries, rich countries would need to ‘degrow’. Against
Transected median nerves in the forearm of two male patients, 12 and 21 years of age, were treated with a chamber technique leaving a 3 to 5 mm gap between the nerve ends. The nerve ends were enclosed in a silicone tube of such a dimension that would not cause compression of the nerve. Post-operative examination including sensory evaluation and assessment of muscle contraction force was carried ou
An experimental model is presented for studying nerve regeneration over gaps of various lengths between the both ends of a severed nerve. After transferring left and right sciatic nerves of rat to the back, the gap between the two nerve ends could be bridged by a preformed, tube-shaped mesothelial chamber of a desired length. When the gap length was 10 mm or less, a well developed nerve structure
Fotograferandet är en av alla de otaliga praktiker som i grunden har förändrats med digitaliseringen och de sociala medierna. Tidigare fotograferade folk företrädesvis i samband med högtider och semesterresor och bilderna hamnade i det privata familjealbumet. Idag bär vi ständigt med oss kameran i mobiltelefonen och knäpper bilder som aldrig förr, vilket har lett till en ”avsakralisering” och ett
Blood oxygenation level-dependent (BOLD) functional MRI is a widely employed methodology in experimental and clinical neuroscience, although its nature is not fully understood. To gain insights into BOLD mechanisms and take advantage of the new functional methods, it is of interest to investigate prolonged paradigms of activation suitable for long experimental protocols and to observe any long-ter
Following the recent Global Carbon Project (GCP) synthesis of the decadal methane (CH4) budget over 2000-2012 (Saunois et al., 2016), we analyse here the same dataset with a focus on quasi-decadal and inter-annual variability in CH4 emissions. The GCP dataset integrates results from top-down studies (exploiting atmospheric observations within an atmospheric inverse-modelling framework) and bottom-
