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

The progression of keratoconus is commonly determined by comparing the results of corneal tomographic measurements on different occasions. However, investigations on the repeatability of measurements are commonly performed within the same day, thus not taking the inter-day variation into account. The effect of keratoconus disease severity on the measurement error is also seldom considered. In this

This paper demonstrates how a strain energy transition approach can be used to remove artificial buckling modes that often occur in stability constrained topology optimization problems. To simulate the structural response, a nonlinear large deformation hyperelastic simulation is performed, wherein the fundamental load path is traversed using Newton’s method and the critical buckling load levels ar

Sjögren’s syndrome (SS) is an exocrinopathy characterized by the hypofunction of salivary glands (SGs). Aquaporin-5 (AQP5); a water channel involved in saliva formation; is aberrantly dis-tributed in SS SG acini and contributes to glandular dysfunction. We aimed to investigate the role of ezrin in AQP5 mislocalization in SS SGs. The AQP5–ezrin interaction was assessed by immuno-precipitation and p

This paper illustrates the transcendental experiences of women who engage in hegemonic masculine spaces such as kendo in Japan. In spite of certain inequalities, women experience unprecedented autonomy and profound personal satisfaction in the dynamic self-expression of their identities in the dojo.
