- Displacement mapping is an effective technique for encoding the high levels of detail of surface models using coarse triangle meshes and displacement maps. These maps are 2D representations containing the distances between the coarse mesh and the surface to represent. Displacement maps have been used in many applications such as ray tracing, image warping, and volume rendering. In this article, we propose modifications to our previous grouping strategy, a new subdivision strategy based on the Modified Butterfly algorithm and new heuristics for the adaptive subdivision procedure, and, finally, the corresponding modifications on our hardware proposal. A meshing scheme and an adaptive subdivision strategy based on displacement mapping reduce the bottleneck between the CPU and graphics pipeline common in high-performance graphics systems.

Forskningsöversikt (refereegranskat)abstract
- Communicative action can be carried out by not only verbal but also embodied means. People regularly use multimodal resources to make sense for each other. Consider a mundane activity, such as a greeting. In addition to the choice of lexical items to fit the relationship, such as “hi,” “yo,” or “good morning, Mister Smith,” extreme prosody featuring high pitch, increased loudness, and extensive lengthening on a “hi” may be necessary for your friend to feel recognized and truly appreciated. In some contexts and relationships, a handshake, a bow, or a hug may be mandatory, while the appropriate duration of those behaviors, the adequate spatial distance, and the exact positions of touch are culturally significant. Across activity settings, bodily behavior is regularly treated as meaningful by coparticipants, as it plays a role in action formation alongside the use of lexicon and grammar. Qualitatively different semiotic resources are juxtaposed so that they mutually elaborate each other and constitute actions within the locally emerging interactional sequences, as understood by the current participants. Aspects such as gaze, gesture, posture, objects, and movement are all potentially recruited to achieve social action, depending on the praxeological context. It is, for example, crucial to pay attention to a specific area in the surrounding space when someone does a pointing gesture or to adjust one’s pace when interacting on the go. We are held socially accountable for our embodied behavior, be it designed for others or not, and the body is constantly interpreted in regard to its action import. Social actions can furthermore be exclusively carried out by the bodies within their spatial, material, and praxeological settings.

Hindgut Innate Immunity and Regulation of Fecal Microbiota through Melanization in Insects
- 2012

- Many insects eat the green leaves of plants but excrete black feces in an as yet unknown mechanism. Insects cannot avoid ingesting pathogens with food that will be specifically detected by the midgut immune system. However, just as in mammals, many pathogens can still escape the insect midgut immune system and arrive in the hindgut, where they are excreted out with the feces. Here we show that the melanization of hindgut content induced by prophenoloxidase, a key enzyme that induces the production of melanin around invaders and at wound sites, is the last line of immune defense to clear bacteria before feces excretion. We used the silkworm Bombyx mori as a model and found that prophenoloxidase produced by hindgut cells is secreted into the hindgut contents. Several experiments were done to clearly demonstrate that the blackening of the insect feces was due to activated phenoloxidase, which served to regulate the number of bacteria in the hindgut. Our analysis of the silkworm hindgut prophenoloxidase discloses the natural secret of why the phytophagous insect feces is black and provides insight into hindgut innate immunity, which is still rather unclear in mammals.
