Disentangling the complex evolutionary history of the Western Palearctic blue tits (Cyanistes spp.) - phylogenomic analyses suggest radiation by multiple colonisation events and subsequent isolation.

Isolated islands and their often unique biota continue to play key roles for understanding the importance of drift, genetic variation, and adaptation in the process of population differentiation and speciation. One island system that has inspired and intrigued evolutionary biologists is the blue tit complex (Cyanistes spp.) in Europe and Africa, in particular the complex evolutionary history of th

Expanding Multimodal Microscopy by High Spectral Resolution Coherent Anti-Stokes Raman Scattering Imaging for Clinical Disease Diagnostics

Over the past years fast label-free nonlinear imaging modalities providing molecular contrast of endogenous disease markers with subcellular spatial resolution have been emerged. However, applications of these imaging modalities in clinical settings are still at the very beginning. This is because single nonlinear imaging modalities such as second-harmonic generation (SHG) and two-photon excited f

Note on symmetric BCJ numerator

We present an algorithm that leads to BCJ numerators satisfying manifestly the three properties proposed by Broedel and Carrasco in [42]. We explicitly calculate the numerators at 4, 5 and 6-points and show that the relabeling property is generically satisfied.

The solid solution Gd2NixCu2-xMg: Large reversible magnetocaloric effect and a drastic change of the magnetism by substitution

Various samples of the solid solution Gd2NixCu2-xMg were synthesized from the elements in sealed tantalum ampoules in an induction furnace. All members crystallize with the tetragonal Mo2FeB2 type structure, space group P4/mbm, and they were characterized on the basis of Guinier powder patterns and energy dispersive X-rays analyses. The lattice parameters decrease with increasing nickel content in

Contrast-to-noise ratio optimization for a prototype phase-contrast computed tomography scanner.

In the field of biomedical X-ray imaging, novel techniques, such as phase-contrast and dark-field imaging, have the potential to enhance the contrast and provide complementary structural information about a specimen. In this paper, a first prototype of a preclinical X-ray phase-contrast CT scanner based on a Talbot-Lau interferometer is characterized. We present a study of the contrast-to-noise ra

The adaptive background of nannandry: dwarf male distribution and fertilization in the moss Homalothecium lutescens

Dwarf males (nannandry) occur in many unrelated, mostly aquatic, groups of organisms. Among land plants they are unique to bryophytes. In this study our aim was to explain variation in frequency of dwarf males and fertilization within populations in the moss Homalothecium lutescens. We compared parameters related to dwarf male presence and sporophyte production in 90 colonies from three localities

Structural and optical properties of self-catalytic GaAs:Mn nanowires grown by molecular beam epitaxy on silicon substrates

Mn-doped GaAs nanowires were grown in the self-catalytic growth mode on the oxidized Si(100) surface by molecular beam epitaxy and characterized by scanning and transmission electron microscopy, Raman scattering, photoluminescence, cathodoluminescence, and electron transport measurements. The transmission electron microscopy studies evidenced the substantial accumulation of Mn inside the catalyzin

Genetic variation in FADS genes is associated with maternal long-chain PUFA status but not with cognitive development of infants in a high fish-eating observational study.

Long-chain n-6 and n-3 PUFA (LC-PUFA), arachidonic acid (AA) (20:4n-6) and DHA (22:6n-3), are critical for optimal brain development. These fatty acids can be consumed directly from the diet, or synthesized endogenously from precursor PUFA by Δ-5 (encoded by FADS1) and Δ-6 desaturases (encoded by FADS2). The aim of this study was to determine the potential importance of maternal genetic variabilit

Evaluating the responsiveness of the ICOAP following hip or knee replacement

Objective: The Intermittent and Constant Osteoarthritis (OA) Pain (ICOAP) questionnaire evaluates the constructs of 'intermittent' and 'constant' pain. Theses are conceptually different from 'pain on activity' and pain 'intensity' as measured by the WOMAC and Chronic Pain Grade (CPG), measures commonly used in OA. The purpose of this study was to evaluate the responsiveness of the ICOAP, and diffe

Anaesthetic conserving device AnaConDa®: dead space effect and significance for lung protective ventilation.

The anaesthetic conserving device AnaConDa(®) (ACD) reflects exhaled anaesthetic agents thereby facilitating the use of inhaled anaesthetic agents outside operating theatres. Expired CO2 is, however, also reflected causing a dead space effect in excess of the ACD internal volume. CO2 reflection from the ACD is attenuated by humidity. This study tests the hypothesis that sevoflurane further attenua

Direct and indirect impacts of climate and socio-economic change in Europe : a sensitivity analysis for key land- and water-based sectors

Integrated cross-sectoral impact assessments facilitate a comprehensive understanding of interdependencies and potential synergies, conflicts, and trade-offs between sectors under changing conditions. This paper presents a sensitivity analysis of a European integrated assessment model, the CLIMSAVE integrated assessment platform (IAP). The IAP incorporates important cross-sectoral linkages between

Contested expectations: Trump International Golf Links Scotland, polarised visions, and the making of the Menie Estate landscape as resource

In initiating the development of a large-scale golf resort in Aberdeenshire, Trump International Golf Links Scotland made a relatively unknown site central to Scottish planning debates. A stretch of land along the North Sea coast north of Aberdeen became linked to new possible futures. Part of the site developed consisted of moving sand dunes given environmental protection as a Site of Special Sci

Patients experiences of information and support during the first six months after heart or lung transplantation.

BACKGROUND: Heart or lung recipients are taught about a new lifestyle, risk factors, medication, food restrictions and exercise so they can take an active role and responsibility for disease management after transplantation. However, little is known about patients' experiences of information and support in these situations. OBJECTIVE: The aim of the study was to illuminate how patients, six months

Recombinant antibodies for the generation of antibody arrays.

Affinity proteomics, mainly represented by antibody microarrays, has in recent years been established as a powerful tool for high-throughput (disease) proteomics. The technology can be used to generate detailed protein expression profiles, or protein maps, of focused set of proteins in crude proteomes and potentially even high-resolution portraits of entire proteomes. The technology provides uniqu
