Locality of order-invariant first-order formulas
2000
A query is local if the decision of whether a tuple in a structure satisfies this query only depends on a small neighborhood of the tuple. We prove that all queries expressible by order-invariant first-order formulas are local.

Global phylogeography and geographical variation in warning coloration of the wood tiger moth (Parasemia plantaginis)
2015
Aim To investigate the phylogeography of the aposematic wood tiger moth (Parasemia plantaginis) across its Holarctic distribution and to explore how its genetic structure relates to geographical differences in hindwing warning coloration of males and females. Males have polymorphic hindwing coloration, while female hindwing coloration varies continuously, but no geographical analyses of coloration or genetic structure exist. Location The Holarctic. Methods We sequenced a fragment of the mitochondrial cytochrome c oxidase subunit I gene (COI) from 587 specimens. We also examined more current population structure by genotyping 569 specimens at 10 nuclear microsatellite loci. Species distribut…
Gender-specific Call of Duty: A Note on the Neglect of Conscription in Gender Equality Indices
2022
We document that existing gender equality indices do not account for gender-specific mandatory peace-time conscription (compulsory military service). This suggests that gender-specific conscription is not considered to be an important gender issue. If an indicator measuring the gender equality of mandatory conscription was to be included in gender equality indices with appropriate weight, then the relative rankings of countries in terms of measured gender equality could be affected. In the context of the Nordic countries, this would mean that Finland and Denmark – the countries with mandatory conscription for men only – would have worse scores with respect to gender equality compared to Swe…
High-Dose Torasemide is Equivalent to High-Dose Furosemide with Hypertonic Saline in the Treatment of Refractory Congestive Heart Failure.
2007
Objective: A randomised, double-blind study was performed to evaluate the effects of the combination of high-dose torasemide and hypertonic saline solution (HSS) infusion versus high-dose furosemide (frusemide) and HSS in the treatment of refractory New York Heart Association class IV congestive heart failure (CHF). Materials and methods: Eighty-four patients (55 males, 29 females) with refractory CHF, aged 55–84 years, with an ejection fraction <35%, serum creatinine <2 mg/dL, blood urea nitrogen ≤60 mg/dL, a reduced urinary volume and a low natriuresis, were randomised to two groups. Group 1 (27 males, 15 females) received an intravenous infusion of furosemide 500mg plus HSS (150mL of 1.4…
Interaction between mesenchymal cells and the posterior iris epithelium in chicken embryos
1977
The iris anlage of 3--10 day old chicken embryos was studied by both light and electron microscopy. Serial semithin sections showed that some of the mesenchymal cells overlying the eye cup moved into the primitive eye cavity by the 3rd day of incubation. On the 4th day some of these cells came into close contact with the basement membrane of the dorsal iris epithelium. The bases of the epithelial cells were flat at this stage. Towards the 10th day they formed cytoplasmic processes which did not penetrate the basement membrane. Fine mesenchymal cytoplasmic processes and a large number of extracellular fibrils developed in the epithelial--mesenchymal interface. The fine mesenchymal processes …
Temporal relationship between genetic and warning signal variation in the aposematic wood tiger moth (Parasemia plantaginis).
2013
Many plants and animals advertise unpalatability through warning signals in the form of colour and shape. Variation in warning signals within local populations is not expected because they are subject to directional selection. However, mounting evidence of warning signal variation within local populations suggests that other selective forces may be acting. Moreover, different selective pressures may act on the individual components of a warning signal. At present, we have a limited understanding about how multiple selection processes operate simultaneously on warning signal components, and even less about their temporal and spatial dynamics. Here, we examined temporal variation of several w…
Changes in predator community structure shifts the efficacy of two warning signals in Arctiid moths
2013
Summary 1. Polymorphism in warning coloration is puzzling because positive frequency-dependent selection by predators is expected to promote monomorphic warning signals in defended prey. 2. We studied predation on the warning-coloured wood tiger moth (Parasemia plantaginis )b y using artificial prey resembling white and yellow male colour morphs in five separate populations with different naturally occurring morph frequencies. 3. We tested whether predation favours one of the colour morphs over the other and whether that is influenced either by local, natural colour morph frequencies or predator community composition. 4. We found that yellow specimens were attacked less than white ones rega…
On ASEM and the Cartography of Asia, Africa and Europe
2015
The ASEM has been growing steadily in size and scope since its inception in 1996, and probably continues to do so in the future. The article tries to map both the history of the concepts for depicting the classical continents and their very flexible boundaries, as well as a possible future course for ASEM from a cartographic point of view, especially in regard to the importance of and interest in Africa that most current ASEM members are showing. This is also considered as one of the future recommendable directions for the expansion of ASEM. peerReviewed
