Plant root traits are diverse and variable, the way in which they interact has consequences for fundamental functions such as anchorage, or services soil fixation. Here, we characterize mechanical related to anchorage (tensile strength, strain, stiffness toughness) at both intra- inter-specific levels examine how covary with other economics space. We grew twelve herbaceous species from contrast...

multiple people detection and tracking is a challenging task in real-world crowded scenes. in this paper, we have presented an online multiple people tracking-by-detection approach with a single camera. we have detected objects with deformable part models and a visual background extractor. in the tracking phase we have used a combination of support vector machine (svm) person-specific classifie...

The vitellogenin/very low density lipoprotein receptor (VTG/VLDL-R), a 95 kDa protein that belongs to the low density lipoprotein receptor gene family, mediates the uptake of yolk precursors by developing follicles during oocyte growth. However, the extent to which variation in VTG/VLDL-R expression plays a role in determining inter-individual variation in reproductive phenotype (e.g. follicle ...

In the era of the extended evolutionary synthesis, which no longer considers natural selection as the only leading factor of evolution, it is meaningful to revisit the legacy of biologists who discussed the role of alternative factors. Here we analyze the evolutionary views of Sergei Meyen (1935-1987), a paleobotanist who argued that the theory of evolution should incorporate a "nomothetical" a...

We propose a novel substrate-bias control scheme for an FD-SOI SRAM that suppresses inter-die variability. The proposed circuits detect inter-die threshold-voltage variation automatically, and then maximize read/write margins of memory cells to supply the substrate bias. We confirmed that a 486-kb 6T SRAM operates at 0.42 V, in which an FS corner can be compared as much as 0.14 V or more. key w...
