Climate change and human activities influence the development of ecosystems, with human demand of ecosystem services altering both land use and land cover. Fossil pollen records provide time series of vegetation characteristics, and the aim of this study was to create spatially continuous reconstructions of land cover through the Holocene in southern Sweden. The Landscape Reconstruction Algorithm

Background: There is a lack of studies of Huntington’s disease (HD) in immigrants. Objective: To study the association between country of birth and incident HD in first-generation immigrants versus Swedish-born individuals and in second-generation immigrants versus Swedish-born individuals with Swedish-born parents. Methods: Study populations included all adults aged 18 years and older in Sweden,

Many contemporary scholars have recently defended the idea that the agency of things is symmetrical and equivalent to human agency. We propose an alternative approach to artefacts’ agency based on a field study concerned with contextually situated observations of the process of design of artefacts in Amazonia. By means of participant observation and interviews, we address the role of artefacts in

Following ‘the audiobook boom’ of recent years, born-audio narratives have emerged: texts produced specifi cally for the audiobook format and intended for mobile audio consumption. Focusing on this category of works, this article examines how the audiobook draws attention to places and situations in which we read, and how these places, in turn, infl uence the content and experience of literary worFollowing ‘the audiobook boom’ of recent years, born-audio narratives have emerged: texts produced specifi cally for the audiobook format and intended for mobile audio consumption.

Waders normally fly with their legs stretched out under the tail, with their feet pointing backwards. Whereas there are a few published records of waders flying with their legs folded forward (like a passerine), with legs and feet tucked in under the belly feathers, the causes and consequences of waders flying with folded legs are poorly understood. Through searching the literature, asking ornitho

Vanuatu is one of the most hazard prone nations in the world and frequently tops the World Risk Report as the nation with the highest overall disaster risk. The devastation wrought by category 5 cyclone Pam (2015), the El Niño drought (2015/16), and volcanic eruptions in Ambae (2018), are but a few recent examples of disasters which have disrupted livelihoods and curtailed development. The Vanuatu

We study the convergence of a semidiscrete scheme for the forward-backward parabolic equation ut = (W?(ux))x with periodic boundary conditions in one space dimension, where W is a standard double-well potential. We characterize the equation satised by the limit of the discretized solutions as the grid size goes to zero. Using an approximation argument, we show that it is possible to flow initial d

We study the asymptotic behavior of deterministic, continuous-time imitation dynamics for population games over networks. The basic assumption of this learning mechanism --- encompassing the replicator dynamics --- is that players belonging to a single population exchange information through pairwise interactions, whereby they get aware of the actions played by the other players and the correspond

The Supreme Leader of the Islamic Republic of Iran, Ali Khamenei, is 81 years old and reportedly in declining health. The question of the succession will be decided by the regime’s Assembly of Experts, who will choose the new Supreme Leader following Khamenei’s death. Six individuals have emerged as possible successors.

Sabotera gasledningar, menar Andreas Malm. Vänta på ”riktig kris”, menar Alf Hornborg. Men det duger inte. Lösningen är att fortsätta agera kollektivt genom civilsamhället med olika metoder för att mobilisera bredare massor och sätta press på makthavare, skriver forskare vid Lunds universitet.

Epicardial adipose tissue has a paracrine effect, enhancing coronary artery atherosclerotic plaque development. This study evaluated epicardial fat volume (EFV), adipokines, coronary atherosclerosis, and adverse cardiovascular events in a cohort of asymptomatic patients with type 2 diabetes mellitus (T2DM). Epicardial fat volume was calculated using data from computed tomography coronary angiogram

Optical wireless networks realized by means of gigabit optical wireless communication (OWC) systems are becoming, in a variety of applications, an important alternative, or a complementary solution, to their fiber-based counterparts. However, performance of the OWC systems can be considerably degraded in periods of unfavorable weather conditions, such as heavy fog, which temporarily reduce the eff

Background. The symptoms of obsessive-compulsive disorder (OCD) are highly heterogeneous and it is unclear what is the optimal way to conceptualize this heterogeneity. This study aimed to establish a comprehensive symptom structure model of OCD across the lifespan using factor and network analytic techniques.Methods. A large multinational cohort of well-characterized children, adolescents, and adu

Background and purpose: Inter-modality image registration between computed tomography (CT) and magnetic resonance (MR) images is associated with systematic uncertainties and the magnitude of these uncertainties is not well documented. The purpose of this study was to investigate the potential uncertainty of gold fiducial marker (GFM) registration for localized prostate cancer and to estimate the i
