Supplementary Material 1 Our method can successfully optimize over 50 octree-based 2 meshes, The results are showed in the following tables. 3 Table 1. Improving Quality of hex-meshes Octree-based method. We use metro tools to compute Hausdorff distance wrt. bounding box diagonal [1]. For each model, the first and second row is input and output, respectively. Model #hexes Err MSJ ASJ airplane1 ...

We present optical and near-infrared (NIR) photometry and spectroscopy as well as modelling of the lightcurves of the Type IIb supernova (SN) 2011dh. Our extensive dataset, for which we present the observations obtained after day 100, spans two years, and complemented with Spitzer mid-infrared (MIR) data, we use it to build an optical-to-MIR bolometric lightcurve between days 3 and 732. To mode...

Ischemic wound complications associated with below-knee amputation (BKA) necessitate conversion to above-knee (AKA) in up 36% of cases. Loss the knee joint has a deleterious impact on rehabilitation, independent living, and health care costs, thus ability promote productive healing BKA flap would be immense value. Cell therapy previously demonstrated pro-angiogenic benefits patients PAD, which ...

The study of factors influencing the adoption and use of information systems in lessdeveloped countries is an important area to address since differences in culture, social structure, and business approaches may have significant effects on the benefits derived from importing Western-influenced IT technology, concepts, and management approaches. This study examines the usage of a decision suppor...

In this special issue of Evolutionary Applications, we draw together a series of diverse studies that provide a sample of some of the ways in which evolution driven by both conscious and unconscious selection by humans has shaped the development of modern agriculture. Agriculture has been a crucible of evolutionary change ever since its inception thousands of years ago, and this change permeate...

Many important biologically active compounds contain quaternary carbon centers. Efficient asymmetric syntheses of these compounds represent a significant challenge in organic chemistry.1 Some catalytic synthetic methods directed toward this problem include prolinecatalyzed aldol reactions,2 Michael additions,3 alkylations with phase-transfer catalysts,4 palladium-catalyzed allylations,5 Heck re...

OBJECTIVES (1) To describe systematically studies that directly assessed the learning curve effect of health technologies. (2) Systematically to identify 'novel' statistical techniques applied to learning curve data in other fields, such as psychology and manufacturing. (3) To test these statistical techniques in data sets from studies of varying designs to assess health technologies in which l...

Lactobacillus helveticus belongs to a group of organisms collectively known as lactic acid bacteria (LAB). This organism has a Generally Recognized as Safe (GRAS) status and displays a number of features that make it particularly suitable for dairy applications. Lactobacillus helveticus is traditionally used in the manufacture of Swiss-type cheeses and long-ripened Italian cheeses such as Emmen...

He lies there on the cover, a large mischievous fishy grin on his face, but with his un-fish-like neck and weight-bearing elbows flexed, as if ready to take a quick dash across an exposed rock as imagined by Gary Larson in a Far Side cartoon as a Great Moment in Evolution. However Tiktaalik roseae probably never did dash out on land, this proto-tetrapod most likely lived its whole life in shall...
