We present an automatic approach for the reconstruction of parametric 3D building models from indoor point clouds. While recently developed methods in this domain focus on mere local surface reconstructions which enable e.g. efficient visualization, our approach aims for a volumetric, parametric building model that additionally incorporates contextual information such as global wall connectivit...

Space-occupying bone lesions present orthopedic surgeons with clinical and operative challenges. Multiple reconstructive procedures have proven successful for small bone lesions but lack the structural support necessary for reconstruction of larger lesions. This study reports the clinical outcomes of patients undergoing excision and reconstruction of large bone lesions with allograft cortical s...

Although the term Big Data has become popular, there is no general consensus about what it really means. Often, many professional data analysts would imply the process of Extraction, Transformation and Load (ETL) for large datasets as the connotation of Big Data. A popular description of Big Data is based on three attributes of data: volume, velocity, and variety (or 3Vs). Nevertheless, it does...

to chloride ingress is one of the most common environmental attacks that lead to the deterioration of concrete structures. Corrosion-related damage to bridge deck overlays, parking garages, marine structures, and manufacturing plants results in millions of dollars spent annually on repairs. This durability problem has received widespread attention in recent years because of its frequent occurre...

AIMS Cryoballoon pulmonary vein (PV) isolation in patients with atrial fibrillation has proven to be effective in short-term and long-term follow-up. To visualise the PV anatomy, pre-ablation contrast pulmonary venography is commonly performed. Three-dimensional (3D) computed tomography (CT) overlay is a new technique creating a live 3D image of the left atrium by integrating a previously obtai...

Introduction: Quantitative evaluation is recommended to improve diagnostic ability and serial assessment of dopamine transporter (DAT) density scans. We decided to compare the ordered subsets expectation-maximization (OSEM) with filtered back-projection (FBP), and to investigate the impact of different iteration and cut-off frequencies on SBR values. Methods</stro...

AIM We aimed to identify specific polymorphisms of genes encoding for vascular endothelial growth factor A (VEGFA), endothelial nitric oxide synthase (eNOS), renin-angiotensin system (angiotensinogen gene [AGT], angiotensinogen type 1 receptor [AGTR1], angiotensin-converting enzyme [ACE]), and heme oxygenase-1 (HMOX-1) in a cohort of preterm infants and correlate their presence with the develop...

background post-mastectomy breast reconstruction is commonly performed in the united states with numerous options available to patients and providers. this study evaluated patient race and provider in prediction of patient satisfaction following post-mastectomy breast reconstruction. methods the patient satisfaction for women who underwent post mastectomy breast reconstruction at university of ...

the present review classifies and describes the multifactorial causes of anterior cruciate ligament (acl) surgery failure, concentrating on preventing and resolving such situations. the article particularly focuses on those causes that require acl revision due to recurrent instability, without neglecting those that affect function or produce persistent pain. although primary acl reconstruction ...
