Humans are characterized by an unusual level of prosociality. Despite this, considerable indirect evidence suggests that biological kinship plays an important role in altruistic behaviour. All previous reports of the influence of kin selection on human altruism have, however, used correlational (rather than experimental) designs, or imposed only a hypothetical or negligible time cost on participan

The subgraph homeomorphism problem is to decide if there is an injective mapping of the vertices of a pattern graph into vertices of a host graph so that the edges of the pattern graph can be mapped into (internally) vertex-disjoint paths in the host graph. The restriction of subgraph homeomorphism where an injective mapping of the vertices of the pattern graph into vertices of the host graph is a

Viral infection may trigger islet autoimmunity, type 1diabetes (T1D), or both. Fluctuating population density of bank voles as a putative reservoir of Ljungan virus has been claimed to be associated with variations in T1D incidence rate (IR). We tested the hypothesis that Ljungan virus antibodies reflecting prior exposure(s) to the virus may be associated with islet autoimmunity, childhood diabete

There are many advantages of combining incretin therapy [glucagon-like peptide-1 (GLP-1) receptor agonists and dipeptidyl peptidase-4 (DPP-4) inhibitors] with insulin therapy as a glucose-lowering strategy in type 2 diabetes. One important advantage is the complementary mode of the mechanistic action of incretin and insulin therapy. Another advantage is the reduction in risk of hypoglycemia and we

Scand J Caring Sci; 2009 Diabetes and pregnancy: women's opinions about the care provided during the childbearing yearBackground: The extended programmes for pregnant women with diabetes, needed to improve pregnancy outcome, might negatively influence the experience of expecting a baby. Aim: To investigate opinions about care during pregnancy, childbirth and the postnatal period among women with d

Landé gJ factors are determined for the three lowest 2P levels in the Cs atom from measured level crossing positions together with a factors determined by zero field double resonance. The hyperfine anomalies between 133Cs, 135Cs and 137Cs are discussed.

Waiting times in cancer care is a patient safety risk that needs increased attention. Mechanisms and effects need to be clarified, waiting time statistics should be openly presented and evidence--based strategies should be implemented. Cancer patient pathways are implemented in Sweden during 2015-2018 and are expected to reduce waiting times for some patient groups, but cannot be expected to prese

This tutorial is devoted to the notion of max-min fairness (MMF), associated optimization problems, and their applications to multi-commodity flow networks.We first introduce a theoretical background for a generic MMF optimization problem and discuss its relation to lexicographic optimization. We next present resolution algorithms for convex MMF optimization, and analyze their properties. In the s

A harmonic oscillator topology displaying an improved phase noise performance is introduced in this paper. Exploiting the advantages yielded by operating the core transistors in class-C, a theoretical 3.9 dB phase noise improvement compared to the standard differential-pair LC-tank oscillator is achieved for the same current consumption. Further benefits derive from the natural rejection of the ta

Revised simulation theory (Goldman, 2006) allows mental state attributions containing some or all of the attributor’s genuine, non-simulated mental states. It is thought that this gives the revised theory an empirical advantage, because unlike theory theory and rationality theory, it can explain egocentric bias (the tendency to over attribute ones’ own mental states to others). I challenge this vi
