Corvids are known for their cognitive flexibility, and many have innovated various forms of tool use. Here, we review tool use and tooling in common ravens (Corvus corax) and describe additional observations. In total, they have used tools in 10 submodes and 11 modes. Of these modes, four were observed in captivity only, four in the wild only and three in both contexts. Five of these modes constit

The first low-energy Coulomb-excitation measurement of the radioactive, semi-magic, two proton-hole nucleus 206Hg, was performed at CERN's recently-commissioned HIE-ISOLDE facility. Two γ rays depopulating low-lying states in 206Hg were observed. From the data, a reduced transition strength B(E2; 2+1 → 0+1) = 4.4(6) W.u. was determined, the first such value for an N=126 nucleus south of 208Pb, wh

Dendritic cells are the sentinels of the immune system, linking the innate and adaptive immune response. Myeloid and dendritic cell models have been successfully used in in vitro approaches to predict adverse outcomes such as skin sensitization. We here exposed a well-characterized human dendritic cell-like cell line to agricultural chemicals, including fungicide formulations, active ingredients,

In an explorative manner this article uses a data driven digital history set-up to focus on broad cultural heritage issues in Sweden during the second half of the 20th century. By distant reading and topic modeling a dataset of 3100 Swedish Government Official Reports (SOU) between 1945–89, the article gives a new perspective of how the Swedish state examined and discussed national cultural herita

BackgroundAmbulatory blood pressure (BP) monitoring has long been used to monitor BP in hypertension and lately emerged as a useful tool to detect hypotensive susceptibility in reflex syncope. However, hemodynamic characteristics in reflex syncope have not been sufficiently explored. The present study investigated the differences between ambulatory BP monitoring profiles associated with reflex syn

Previous research indicates that firms pay a premium to poach workers from exporting firms if experience working for an internationally engaged firm reduces trade costs. Because international experience is less valuable to non-exporters, we would expect to see differences in recruitments between firms that are internationally engaged and those that serve only the domestic market. Moreover, increas

This article analyses how UN Security Council resolution 1325 and the Women, Peace, Security (WPS) agenda have been adopted in the Middle East and North Africa. The region faces huge security challenges triggered by recurrent armed conflicts, terrorism and wars both between and within states. Four thematic areas have been chosen: (1) terrorism; (2) peace negotiations; (3) state-building; and (4) d

The effect of 3,4,9,10-perylenetetracarboxylic dianhydride (PTCDA) adsorption on the physical properties of the two-dimensional (2D) atomic layer superconductor (ALSC) In/Si(111)-(7×3) has been studied by angle-resolved photoelectron spectroscopy, transport measurements, and scanning tunneling microscopy. Hole doping from the adsorbed molecules has been reported to increase the superconducting tra

Increasing survival rates for childhood cancer have brought attention to the high level of burden of cancer and its treatment. Improving supportive care for children throughout their cancer trajectory is thus important and could reduce the difficulties related to treatment, including time-consuming treatments and the waiting time associated with treatment procedures. The aim of this study is to de
