Thirty years of search and capture: The complex simplicity of mitotic spindle assembly
Journal of Cell Biology, 2015 Cell division is enacted by a microtubule-based, self-assembling macromolecular machine known as the mitotic spindle. In 1986, Kirschner and Mitchison proposed that by undergoing dynamic cycles of growth and disassembly, microtubules search for ...

Cell, 2004 Although cortical nonmuscle myosin II has long been implicated in cytokinetic aspects of cell division, there has never been strong evidence that it plays a role in the organization of the mitotic spindle. ([this issue of Cell]) use a number of methods to show that cortical myosin II is in fact important for spindle assembly in higher eukaryotic cells,

A comparative study of using spindle motor power and eddy current for the detection of tool conditions in milling processes [PDF]
, 2015 This paper investigates the use of the power of the driving motor of a CNC spindle in comparison to two perpendicular eddy current sensors for the detection of tool wear in milling processes. Monitoring the power through the current profile is a low cost

A comparison of the distribution of actin and tubulin in the mammalian mitotic spindle as seen by indirect immunofluorescence [PDF]
, 1977 Rabbit antibodies against actin and tubulin were used in an indirect immunofluorescence study of the structure of the mitotic spindle of PtK1 cells after lysis under conditions that preserve anaphase chromosome movement. During early prophase there is no

The mitotic spindle checkpoint [PDF]
Current Biology, 2001 Fantastic progress has been made in understanding the spindle checkpoint, the guardian of balanced chromosome segregation. However, several basic questions and many details remain to be worked out. In the meantime, the use of chimeric fluorescent proteins and ever better imaging technology has enhanced the stunning videos of mitosis made today ...

Ball and Spindle Convexity with respect to a Convex Body [PDF]
, 2012 Let $C\subset {\mathbb R}^n$ be a convex body. We introduce two notions of convexity associated to C. A set $K$ is $C$-ball convex if it is the intersection of translates of $C$, or it is either $\emptyset$, or ${\mathbb R}^n$.
