Geometric calibration is a critical component in cone-beam computed tomography (CBCT), ensuring that the spatial relationships between the X‐ray source, detector and the object are accurately ...

The classic CFU assay uses a dilution series to measure viable cell concentrations across the many orders of magnitude that exist in nature; but this comes at the expense of time and resources. In ...

Pine cones are a well-known bionic model for constructing artificial actuators. However, little attention has been paid to the fact that the hygroscopic motion of pine cones is an ultra-slow process.

Nature is home to perfectly formed shapes and vibrant colors. When seen up close, snowflakes have incredibly perfect geometric shapes. Circles are found in tree stumps and oceans, while straight ...

Pine cones are a familiar holiday decoration, but how much do you really know about them? While many types of trees have cones, you’ve probably seen cones from pine, spruce, fir and cedar trees ...
