11. Holistic Grasping: Affordances, Grasp Semantics, Task Constraints
Sammanfattning : Most of us perform grasping actions over a thousand times per day without giving it much consideration, be it from driving to drinking coffee. Learning robots the same ease when it comes to grasping has been a goal for the robotics research community for decades. LÄS MER
12. Light’EM up! : structural characterization of light-driven membrane protein complexes by cryogenic electron microscopy
Sammanfattning : Photosynthesis is probably the most important process for allowing life to develop into the diverse forms we see today. In this process, solar radiation is used to convert CO2 into biomass. From this process, we obtain oxygen to breathe, sources of food (plant biomass), and the potential for clean and sustainable energy. LÄS MER
13. Three-dimensional Virtual Histology of Early Vertebrate Scales Revealed by Synchrotron X-ray Phase-contrast Microtomography
Sammanfattning : Vertebrate hard tissues first appeared in the dermal skeletons of early jawless vertebrates (ostracoderms) and were further modified in the earliest jawed vertebrates. Fortunately, histological information is usually preserved in these early vertebrate fossils and has thus been studied for more than a century, done so by examining thin sections, which provide general information about the specific features of vertebrate hard tissues in their earliest forms.

14. Novel methods for mapping genome organization and genome fragility in the 3D space of the nucleus
Sammanfattning : For over a century, scientists have been trying to understand how the DNA molecule that is so tightly packed in the micro space of the nucleus sustains critical cellular processes such as transcription, replication or the maintenance of genetic information. Despite the huge effort of researchers around the world, we know relatively little. LÄS MER
15. Energy-momentum conserving time-stepping algorithms for nonlinear dynamics of planar and spatial Euler-Bernoulli/Timoshenko beams
Sammanfattning : Large deformations of flexible beams can be described using either the co-rotational approach or the total Lagrangian formalism. The co-rotational method is an attractive approach to derive highly nonlinear beam elements because it combines accuracy with numerical efficiency. LÄS MER
