The goal of this paper is to derive in the two-dimensional case necessary and sufficient minimality conditions in terms of the second variation for the functional v 7→ ∫ Ω ( |∇v| + χ{v>0}Q ) dx, introduced in a classical paper of Alt and Caffarelli. For a special choice of Q this includes water waves. The second variation is obtained by computing the second derivative of the functional along su...

PURPOSE This study aimed to investigate the clinical significance of serum alanine aminotransferase (ALT) levels in children with nonalcoholic fatty liver disease (NAFLD) and the effect of lifestyle intervention on NAFLD. METHODS The clinical data of 86 children diagnosed with NAFLD were reviewed retrospectively. Forty-six patients belonged to the elevated ALT group and 40 to the normal ALT g...

BACKGROUND Evidence suggests that the predictive value of serum alanine aminotransferase (ALT) levels for prognosis, measured by indices such as all-cause mortality and medical costs, may be modified by body mass index (BMI). However, the relationship between serum ALT and BMI has not been satisfactorily elucidated. METHODS Four thousand, five hundred and twenty-four community dwelling Japane...

We use unique panel data on the evolution of transparent budget procedures in the American states over the past three decades to explore the political and economic determinants of fiscal transparency. Our preliminary results suggest that more equal political competition and power sharing are associated with both greater levels of fiscal transparency and increases in fiscal transparency during t...

Recent surveys have shown that the majority of websites are not accessible. Despite legal obligations and the importance of the internet for disabled people, most websites fail to reach a basic level of accessibility, yet web developers are not short of accessibility guidelines and recommendations. This preliminary study consists of a meta-review of web accessibility studies in order to identif...
