UV mapping is a classical problem in computer graphics aiming at computing planar parameterization of the input mesh with lowest possible distortion while minimizing seams length. Recent works propose optimization methods for solving these two joint problems same time variational models, but they tend to be slower than other cutting methods. We present new approach this inspired by Ambrosio-Tor...

BACKGROUND To date, no surgical technique to treat posterolateral knee instability anatomically reconstructs the 3 major static stabilizing structures of the posterolateral knee: the fibular collateral ligament, the popliteus tendon, and the popliteofibular ligament. HYPOTHESIS Static varus and external rotatory stability would be restored to the reconstructed knee with a posterolateral knee ...

The global solved problem is the calculation of the parameters of ceramic material from a set of destruction tests of ceramic heads of total hip joint endoprosthesis. The standard way of calculation of the material parameters consists in carrying out a set of 3 or 4 point bending tests of specimens cut out from parts of the ceramic material to be analysed. In case of ceramic heads, it is not po...

Subjects and Methods The study was based on 33 knees in 30 patients who underwent TKR due to varus osteoarthritis (26 females, 4 males mean age of 69.9 years). All the operations were performed by two of the senior authors (Y.K. and A.K.) using posterior stabilized prostheses. Bone cut in the proximal tibial was made using an extramedullary alignment guide to be perpendicular to the long axis. ...

The paper deals with calculation of the parameters of ceramic material from a set of destruction tests of ceramic heads of total hip joint endoprosthesis. The standard way of calculation of the material parameters consists in carrying out a set of 3 or 4 point bending tests of specimens cut out from parts of the ceramic material to be analysed. In case of ceramic heads, it is not possible to cu...

BACKGROUND In most patients with rheumatoid arthritis (RA), Disease Activity Score 28-joint count C reactive protein (DAS28-CRP) is lower than DAS28 erythrocyte sedimentation rate (DAS28-ESR), suggesting that use of the DAS28-ESR cut-off to assess high disease activity (HDA) with DAS28-CRP may underestimate the number of patients with HDA. We determined the DAS28-CRP value corresponding to the ...

This report describes a case of spontaneous fibroblastic osteosarcoma in the humerus of a lion from a private park in Perugia, Italy. The tumor had an irregular, smooth, brown surface and a generally firm, rubbery consistence with gritty to hard areas interspersed. The mass was poorly vascularized with areas of necrosis at the periphery. The cut surface showed a multilobulated mass that had bre...

This paper proposes statistic learning based Q-learning algorithm for Multi-Agent System, the agent can learn other agents’ action policies through observing and counting the joint action, a concise but useful hypothesis is adopted to denote the optimal policies of other agents, the full joint probability of policies distribution guarantees the optimal action choice to the learning agent. The a...

BACKGROUND. The objective of this study is to evaluate the response of the musculoskeletal system to enzyme replacement therapy in a group of patients with Mucopolysaccharidosis (MPS). MATERIAL AND METHODS. A retrospective study was done based on records from 22 patients with different types of MPS (I, II and VI) who were treated with enzyme replacement therapy (ERT). Patient data were evaluate...
