Emlen funnel experiments revisited : methods update for studying compass orientation in songbirds

Migratory songbirds carry an inherited capacity to migrate several thousand kilometers each year crossing continental landmasses and barriers between distant breeding sites and wintering areas. How individual songbirds manage with extreme precision to find their way is still largely unknown. The functional characteristics of biological compasses used by songbird migrants has mainly been investigat

Lifestyle and glycaemic control before and after the onset of type 2 diabetes

Type 2 diabetes (T2D) is a complex disease with widespread physiological insults to the regulation of metabolic homeostasis, above all glycaemic regulation. The pathogenesis of T2D and its progression is broadly understood to be through a gradual decrease in peripheral insulin sensitivity, a compensatory rise in insulin secretion, and a gradual decline in beta-cell function, resulting in glycaemic

Burden of disease in psoriasis and psoriatic arthritis. Occurrence, healthcare use, costs and health outcomes.

Psoriasis (PSO) and psoriatic arthritis (PsA) are two related chronic inflammatory diseases. A proportion of people with PSO also develop PsA. PSO and PsA seem to have multiple impacts; from the health and well-being of the individual; to the need for healthcare resources for disease management; to the loss of productivity. Compared with other chronic diseases, such as heart disease and diabetes,

Simultaneous design of proportional–integral–derivative controller and measurement filter by optimisation

A method for optimization of PID controller parameters and measurement filter time constant is presented. The method differs from the traditional approach in that the controller and filter parameters are simultaneously optimized, as opposed to standard, sequential, design. Control performance is maximized through minimization of the integrated absolute error (IAE) caused by a unit step load distur

Expanded molecular phylogeny of the genus Bicyclus (Lepidoptera : Nymphalidae) shows the importance of increased sampling for detecting semi-cryptic species and highlights potentials for future studies

The genus Bicyclus is one of the largest groups of African butterflies, but due to the generally cryptic nature and seasonal variation of adult wing patterns, there has been a lot of systematic confusion. With a large research community working with the model species Bicyclus anynana there has been increasing interest in the evolutionary history of the genus. A previous phylogeny started to unrave

Comparison of isoelectric points of single-crystal and polycrystalline α-Al2O3 and α-Fe2O3 surfaces

The surface charging behavior as a function of pH and isoelectric points (IEPs) of single-crystal α-Al2O3 (0001) and (1102) and α-Fe2O3 (0001) was determined by streaming potential measurements using an electrokinetic analyzer. The IEPs of α-Al2O3 (0001) and (11-02)$(1\overline1 02)$ and α-Fe2O3 (0001) were found to be 4.5, 5.1, and 6.5, respectively. These IEP values for oriented single crystals

Generation and analyses of human synthetic antibody libraries and their application for protein microarrays

Antibody-based proteomics offers distinct advantages in the analysis of complex samples for discovery and validation of biomarkers associated with disease. However, its large-scale implementation requires tools and technologies that allow development of suitable antibody or antibody fragments in a high-throughput manner. To address this we designed and constructed two human synthetic antibody frag

Improved Relay Autotuning using Normalized Time Delay

The relay autotuner provides a simple way offinding PID controllers of sufficient performance. By usingan asymmetric relay function the excitation of the process isimproved. This gives better models, and hence a better tuning,without increasing the time consumption or complexity of theexperiment. Some processes demand more accurate modelingand tuning to obtain controllers of sufficient performanceThe relay autotuner provides a simple way offinding PID controllers of sufficient performance.

High presence of extracellular hemoglobin in the periventricular white matter following preterm intraventricular hemorrhage

Severe cerebral intraventricular hemorrhage (IVH) in preterm infants continues to be a major clinical problem, occurring in about 15-20% of very preterm infants. In contrast to other brain lesions the incidence of IVH has not been reduced over the last decade, but actually slightly increased. Currently over 50% of surviving infants develop post-hemorrhagic ventricular dilatation and about 35% deve

Physical risk factors influencing wheeled mobility in children with cerebral palsy : A cross-sectional study

Background: There is a lack of understanding of the factors that influence independent mobility and participation in meaningful activities. The purpose of this study was to analyse physical factors influencing independent use of manual and power wheelchairs in a total population of children with cerebral palsy (CP). Methods: A cross-sectional study based on the most recent examination of all child

Tools and pipelines for interpreting the impacts of genetic variants

Next generation sequencing (NGS) methods have been widely used for diagnosis. As time and cost of sequencing has reduced sharply during the last decade, genome and exome-wide sequencing have increasingly been used. The genome and exome projects produce large amounts of variation data and the clinical relevance of large proportions of them are not known. Among various types of genetic variations, t

Innovation for tackling grand challenges : Cleantech industry dynamics and regional context

Grand challenges such as climate change put focus away from innovations and innovation policy as engines of economic growth towards fulfilling societal goals and sighting sustainable development. The literature on the geography of innovation has provided valuable insights on innovation activities of firms and industries and how they are positively influenced by co-location. In particular, short ge

Can the Study of Mission Become Postcolonial? : On Mission Studies in Today's World

The roots of mission studies are in the western missionary movement which had its heyday at the same time with the colonialist era. Academic mission studies which began a hundred years ago were confessional and served the interests of the western missions. With decolonisation and indigenisation of the majority world churches also mission studies underwent great changes. The study of world Christia

Exocomet signatures around the A-shell star φ Leonis?

We present an intensive monitoring of high-resolution spectra of the Ca ii K line in the A7IV shell star φ Leo at very short (minutes, hours), short (night to night), and medium (weeks, months) timescales. The spectra show remarkable variable absorptions on timescales of hours, days, and months. The characteristics of these sporadic events are very similar to most that are observed toward the debr

Supported employment adapted for people with affective disorders : A randomized controlled trial

Background While effective vocational methods for gaining employment exist for people with schizophrenia and similar conditions, no evidence exists with regard to people with affective disorders. We aimed to study the effectiveness of a newly developed Individual Enabling and Support (IES) model adapted for the target group and compared to traditional vocational rehabilitation (TVR). Methods An as

Subpopulations of T regulatory cells in blood stem cell harvests influence development of acute graft versus host disease in allogeneic transplant recipients

Background: CD4+ FoxP3+ regulatory T cells (Tregs) are the potent suppressors of activation and proliferation of conventional T cells. Tregs subdivided by their expression of FoxP3 and CD45RA identify clinically important functional subsets. Methods: We analyzed Treg subpopulations in hematopoietic stem cell harvests (SCH) from 22 allogeneic (matched unrelated and sibling) donors with flow cytomet
