The covid-19 pandemic was characterized by a series of variants of concern, different strains of SARS-CoV-2 which had a serious impact on transmission. One of these, denoted Omicron, dominated in early 2022 and caused covid-19 cases to soar. The increased transmission during the Omicron wave triggered hospitals to further strengthen airborne precautions. The reason for this surge in cases during O
The cross-section of associated J/ψ-ψ(2S) production in proton-proton collisions at a centre-of-mass energy of (Formula presented.) TeV is measured using a data sample corresponding to an integrated luminosity of 4.2 fb−1, collected by the LHCb experiment. The measurement is performed for both J/ψ and ψ(2S) mesons having transverse momentum pT< 14 GeV/c and rapidity 2.0 < y < 4.5, assuming negligi
Emmer (1993) claimed creativity to be a bridge between art and mathematics exemplified (www. olats.org/colloque/textes/texte7.shtml) in his traveling exhibition The Eye of Horus: Art and Mathematics (Emmer, 1990). A shared language is needed to make bridges between science, art and metaphysics (Thiessen, 1998). Scientific phenomena and concepts need to be possible to isolate for better understandi
This study investigates the publication and reception of the Latin American boom literature in Sweden from 1960 to 1990, focusing on Julio Cortázar, Carlos Fuentes, Gabriel García Márquez and Mario Vargas Llosa. It analyses the extent of Swedish translations of their works and the type and amount of attention they received in the Swedish press. Using a bibliometric approach for the translations, aThis study investigates the publication and reception of the Latin American boom literature in Sweden from 1960 to 1990, focusing on Julio Cortázar, Carlos Fuentes, Gabriel García Márquez and Mario Vargas Llosa.

The understanding of small antennas has evolved tremendously since the initial investigations close to 80 years ago. In this presentation, we highlight some fundamental results on Q-factor, bandwidth, and gain.
Amidst criticism of the concept of “the learning organisation” there is a perspective which is both critical of, and open to, innovative ways of developing the notion of a learning organisation. This article contributes to this perspective by examining the learning practices of a feminist NGO which operates across Southern Africa. The ways in which this NGO has interpreted the idea of a learning o
Impalas are unusual among bovids because they have remained morphologically similar over millions of years-a phenomenon referred to as evolutionary stasis. Here, we sequenced 119 whole genomes from the two extant subspecies of impala, the common (Aepyceros melampus melampus) and black-faced (A. m. petersi) impala. We investigated the evolutionary forces working within the species to explore how th
UNLABELLED: Serine protease inhibitors (serpins) constitute the largest family of protease inhibitors expressed in humans, but their role in infection remains largely unexplored. In infected macrophages, the mycobacterial ESX-1 type VII secretion system permeabilizes internal host membranes and causes leakage into the cytosol of host DNA, which induces type I interferon (IFN) production via the cy
Ancient genomes provide a tool to investigate the genetic basis of adaptations in extinct organisms. However, the identification of species-specific fixed genetic variants requires the analysis of genomes from multiple individuals. Moreover, the long-term scale of adaptive evolution coupled with the short-term nature of traditional time series data has made it difficult to assess when different ad
The blue wildebeest (Connochaetes taurinus) is a keystone species in savanna ecosystems from southern to eastern Africa, and is well known for its spectacular migrations and locally extreme abundance. In contrast, the black wildebeest (C. gnou) is endemic to southern Africa, barely escaped extinction in the 1900s and is feared to be in danger of genetic swamping from the blue wildebeest. Despite t
Predation is an important ecological process that can significantly impact the maintenance of ecosystem services. In arctic environments, the relative ecological importance of predation is thought to be increasing due to climate change, partly because of increased productivity with rising temperatures. Therefore, understanding predator-prey interactions in arctic ecosystems is vital for the sustai
Genomic studies of species threatened by extinction are providing crucial information about evolutionary mechanisms and genetic consequences of population declines and bottlenecks. However, to understand how species avoid the extinction vortex, insights can be drawn by studying species that thrive despite past declines. Here, we studied the population genomics of the muskox (Ovibos moschatus), an
During the Swedish-Russian Tundra Ecology -94 expedition one of the goals was to describe the local population fluctuations of Siberian lemmings over the Eurasian tundra. In order to compensate for the lack of repeated sampling, we used 4 different estimates to determine the phase position of the lemming populations at the different sites: i) the number of lemmings trapped per unit time; ii) the a
