Background Human papillomavirus (HPV) vaccination protects against HPV, a necessary risk factor for cervical cancer. We now report results from population-based follow-up of randomised cohorts that vaccination provides HPV-type-specific protection against invasive cancer. Methods Individually and/or cluster randomised cohorts of HPV-vaccinated and non-vaccinated women were enrolled in 2002-2005. H
Migration allows animals to exploit spatially separated and seasonally available resources at a continental to global scale. However, responding to global climatic changes might prove challenging, especially for long-distance intercontinental migrants. During glacial periods, when conditions became too harsh for breeding in the north, avian migrants have been hypothesized to retract their distribu
BACKGROUND: Type 2 diabetes is one of the leading causes of chronic kidney failure, which increases globally and represents a significant threat to public health. People from the Middle East represent one of the largest immigrant groups in Europe today. Despite poor glucose regulation and high risk for early-onset insulin-deficient type 2 diabetes, they have better kidney function and lower rates
AIMS: Our aim was to study the incidence of type 2 diabetes in a population-based cohort of Swedish and Iraqi born individuals, focussing on traditional risk factors, insulin action, insulin secretion and ethnicity.MATERIALS AND METHODS: The cohort consisted of 1164 Iraqi and 693 Swedish-born citizens. We investigated the association between new-onset type 2 diabetes and the predictors including l
Regional development is a dynamic process where relatively stable periods are interrupted by phases of more rapid transformation and disruption. Such dynamics are heavily influenced by the scope and nature of knowledge networks. Trust is a key mechanism influencing the mobilisation of networks for learning and innovation and thereby an important factor for understanding regional development. This
Single occupancy households consume more resources per capita, and demographics suggest single occupancy is now widespread in many countries. Environmental policies need to adjust to include per capita consumption to account for occupancy and efficient use of resources. Diana Ivanova, Tullia Jack, Milena Büchs and Kirsten Gram-Hanssen explain how the sharing of resources at domestic, neighbourhood
Erfarenheterna av att arbeta digitalt är nu många och användbara. Pandemin slog hårt, men den har också lett till att digitala barnsjukdomar kunnat utrotas, skriver de två forskarna Claire Hoolohan och Tullia Jack.
Inspired by work of Ladkani and Groth–Šťovíček, we explain how to construct generalisations of the classical reflection functors of Bernšteĭn, Gel′fand, and Ponomarev by means of the Grothendieck construction.
We show that the perfect derived categories of Iyama’s d-dimensional Auslander algebras of type A are equivalent to the partially wrapped Fukaya categories of the d-fold symmetric product of the 2-dimensional unit disk with finitely many stops on its boundary. Furthermore, we observe that Koszul duality provides an equivalence between the partially wrapped Fukaya categories associated to the d-fol
These notes are an expanded version of my talk at the ICRA 2018 in Prague, Czech Republic; they are based on joint work with Tobias Dyckerhoff and Tashi Walde. In them we relate Iyama's higher Auslander algebras of type A to Eilenberg-Mac Lane spaces in algebraic topology and to higher-dimensional versions of the Waldhausen S-construction from algebraic K-theory.
We develop a novel combinatorial perspective on the higher Auslander algebras of type A, a family of algebras arising in the context of Iyama's higher Auslander–Reiten theory. This approach reveals interesting simplicial structures hidden within the representation theory of these algebras and establishes direct connections to Eilenberg–MacLane spaces and higher-dimensional versions of Waldhausen's
We introduce higher dimensional analogues of the Nakayama algebras from the viewpoint of Iyama's higher Auslander–Reiten theory. More precisely, for each Nakayama algebra A and each positive integer d, we construct a finite dimensional algebra A(d) having a distinguished d-cluster-tilting -module whose endomorphism algebra is a higher dimensional analogue of the Auslander algebra of A. We also con
This article consists of an introduction to Iyama's higher Auslander–Reiten theory for Artin algebras from the viewpoint of higher homological algebra. We provide alternative proofs of the basic results in higher Auslander–Reiten theory, including the existence of d-almost-split sequences in d-cluster-tilting subcategories, following the approach to classical Auslander–Reiten theory due to Ausland
