Article
The genus Baccharis (Asteraceae) comprises over 440 species distributed along North and South America. Some species of this genus have remarkable invasiveness, and one of these species is the South American shrub Baccharis dracunculifolia DC. Most of the introductions of non-indigenous species are held indirectly through trade, so it is believed th...

Tropane alkaloids and terpenoids are widely used in the medicine and pharmaceutic industry and evolved as chemical defenses against herbivores and pathogens in the annual herb Datura stramonium (Solanaceae). Here, we present the first draft genomes of two plants from contrasting environments of D. stramonium . Using these de novo assemblies, along...

Scaffolds have proven to be an excellent option for the regeneration of bone tissues; since they present excellent results of architecture, composition, and functionality. Therefore, scaffolds can be used as implants to repair bones and show guided regeneration, allowing complete restructuring of damaged tissue, as well as allowing the site where t...
Article
There are numerous methods for producing scaffolds to be applied in bone tissue engineering. However, the best method of scaffold production is essential to consider, with respect to their chemical composition and mechanical and structural properties, so that debris is not produced when the scaffolds are evaluated in vitro or in vivo. The primary a...
Article
Scaffolds for bone tissue applications have been an outstanding alternative to repair and regenerate bone tissue defects caused by traumas or illness. There are many methods available to fabricate porous scaffold such as solvent casting, gas bubble, phase separation, electrospinning, particle-leaching, among others. The particle-leaching technique...

Pollination and seed dispersal patterns determine gene flow within plant populations. In tropical forests, a high proportion of trees are dioecious, insect pollinated and dispersed by vertebrates. Dispersal vectors and density dependent factors may modulate realized gene flow and influence the magnitude of Fine Scale Genetic Structure (FSGS), affec...
Chapter
n this paper we present a fast data parallel implementation of the Radix Sort on the Direct Compute software development kit (SDK). We also discuss in detail the various optimization strategies that were used to increase the performance of our Radix Sort, and we show how these strategies can be generalized for any video card that supports the Direc...
Article
Scaffolds have been showed to be an option for bone tissue regeneration, owing to their excellent results in architecture design, composition, and functionality. Consequently, scaffolds can function as implants to repair bones and guide regeneration, enabling the complete restoration of tissue functionality at their implantation site. In the presen...
Article
β-Tricalcium phosphate (β-TCP) is one of the most investigated calcium phosphates to be used in bone tissue regeneration. Nowadays, β-TCP has been synthetized by different methods that allow obtaining different morphologies with chemical compositions similar to the bone tissue, broadening the possibilities of use. In this work, β-TCP powders were o...
Article
This paper proposes an efficient construction scheme for Bounding Volume Hierarchies as a complete tree. This construction offers up to 4X faster construction times than binned-SAH and offers competitive ray traversal performance. The construction is fully parallelized on x86 CPU architectures, it takes advantage of the 8-wide vector units and expl...

This paper presents an efficient space partitioning approach for building high quality Bounding Volume Hierarchies using x86 CPU architectures. Using this approach a structure can be built faster than a binned-SAH heuristic while the structure preserves its quality. This method consists of a hybrid implementation that uses binned-SAH for the top le...

This paper proposes an efficient method to extract the geometric characteristics of meshes, to make an assertive choice of an acceleration structure for ray tracing in real-time. This method automatically decides the best acceleration structure type for a specific scene, given the geometric information. This paper describes which geometric characte...

This paper presents an efficient space partitioning approach for building high quality Linear Bounding Volume Hierarchy (LBVH) acceleration structures for ray tracing. This method produces more regular axis-aligned bounding boxes (AABB) into a complete binary tree. This structure is fully parallelized on GPU and the process to efficiently paralleli...

Conference Paper
This paper proposes a method to characterize surface meshes in order to select an acceleration structure that minimizes construction time and maximizes ray tracing performance according to the characteristics of a specific scene. The proposed algorithm has linear complexity. We analyze which characteristics are important to make an assertive select...
