Prolonged release from PLGA/HAp scaffolds containing drug-loaded PLGA/gelatin composite microspheres
, 2011 Porous scaffolds that can prolong the release of bioactive factors are urgently required in bone tissue engineering. In this study, PLGA/gelatin composite microspheres (PGMs) were carefully designed and prepared by entrapping poly(L: -lactide-co ...

Basis Networks: Learning basis functions for free‐form triangulations
Computer Graphics Forum, EarlyView.Abstract We present a framework for learning compactly supported basis functions that define tangent continuous surfaces based on coarse irregular triangle meshes. The basis functions are represented as MLPs. Smoothness of the basis functions is achieved by using the values of Loop basis functions as the parameterization of the surface.

Medial Axis Aware Learning of Signed Distance Functions
Computer Graphics Forum, EarlyView.Abstract We propose a novel variational method to compute a highly accurate global signed distance function (SDF) to a given point cloud. To this end, the jump set of the gradient of the SDF, which coincides with the medial axis of the surface, is explicitly taken into account through a higher‐order variational formulation that enforces linear growth ...

As‐Rigid‐As‐Possible Regularization for Implicit Surfaces
Computer Graphics Forum, EarlyView.Abstract Implicit surface representations have regained popularity because of their use in machine learning. A common component in optimization is regularization, penalizing the deviation of the surface from its original shape. The popular as‐rigid‐as‐possible (Arap) energy strikes a good compromise between realistic deformation behavior and efficient ...

Recycling Oriented Characterization of PGMs from Spent Automotive Catalysts (ACCs)
, 2021 Platinum Group Metals (PGMs) are key critical metals for Europe, that is dependent on export from the main producing countries, mainly South Africa and Russia, which together are responsible for 75 to 80% of the PGM world mine supply. On the demand side,

Compactly supported detail field for high quality neural implicit surfaces
Computer Graphics Forum, EarlyView.Abstract Neural implicit surfaces are a powerful tool for encoding a surface as the zero level set of a neural function. Trained using gradient‐descent based optimizers, these methods however suffer from a low‐frequency bias that prevents them to fit fine details of the surface.

Developments in Platinum-Group Metals as Dual Antibacterial and Anticancer Agents
Journal of Chemistry, 2019 Platinum-group (PG) complexes have been used as antibacterial and anticancer agents since the discovery of cisplatin. The science world still requires improvement on these complexes because of multidrug and antineoplastic resistances.

Optimized and Aligned Anisotropic Monte Carlo Sampling Patterns
Computer Graphics Forum, EarlyView.Abstract Path tracing uses Monte Carlo integration to solve the rendering equation by evaluating the integrand at random sampling points. The convergence rate of the error can be significantly improved by using correlated instead of random sampling, especially on smooth integrands.
