The optimal levels of vitamin D and the best treatment for vitamin D deficiency are the object of intense discussion. As for the threshold value of 25-hydroxyvitamin D (25(OH)D) defining a sufficient vitamin D status, a dedicated Committee of the Institute of Medicine recently stated that a serum concentration of at least 50 nmol/L meets the needs of at least 97.5% of the population [1, 2]. The...
During the past several years, point density covering topographic objects with airborne lidar (Light Detection And Ranging) technology has been greatly improved. This achievement provides an improved ability for reconstructing more complicated building roof structures; more specifically, those comprising various model primitives horizontally and/or vertically. However, the technology for automa...
Building boundary is necessary for the real estate industry, flood management, and homeland security applications. The extraction of building boundary is also a crucial and difficult step towards generating city models. This study presents an approach to the tracing and regularization of building boundary from raw lidar point clouds. The process consists of a sequence of four steps: separate bu...

The risks and benefits of children and adolescents par‐ ticipating in elite sports have long been debated. Reports of growth retardation in elite gymnasts and degenerative joint disease in the elbows of young baseball players have caused anxiety among parents and sporting bodies. In contrast, Ericsson’s theory of deliberate practice dictates the need for high volumes of training at a young age ...
Background and Objective: Staphylococcus aureus is an important pathogen causing a wide range of infections in hospitals and is known due to its resistance to antibiotics. Novel methods of nanotechnology and the effective combination of different antimicrobial mechanisms can be compelling approaches to treat infectious diseases. The aim of this study was to investigate the antimicrobial effect ...
