Protein phosphorylation has been suggested as an important control mechanism for the events leading toward the initiation and completion of mitosis. Using a monoclonal antibody recognizing a class of phosphoproteins abundant in mitotic cells, we demonstrated the localization of a subset of these phosphoproteins to several discrete mitotic structures. Patchy immunofluorescence was present in the...

A data set is a matrix D = {f (1), ..., f (m)} (D ∈ Rnx×m), where the rows correspond to objects and the columns are features f (i). A data set is generated by a structure, parameterized by a symmetric matrix S ∈ Rnt×nt . Each row/column in S corresponds to a node in the graph. The set of object nodes is called X and cluster nodes is called Z, where nx and nz are their cardinalities, combining ...

This paper presents a creativity support tool, called FreePub, to collect and organize scientific material using mindmaps. Mindmaps are visual, graph-based represenations of concepts, ideas, notes, tasks, etc. They generally take a hierarchical or tree branch format, with ideas branching into their subsections. FreePub supports creativity cycles. A user starts such a cycle by setting up her dom...

Material Flow Control (MFC) mechanisms control the movement of jobs through a set stationery capacity resources on shop floor. Although objective MFC is item-centric, i.e. to flow individual jobs, most existing are resource-centric, focus managing resources. While this was justified by technical constraints real-time information feedback, advances in technology allow for new designs. In particu...

A centriolar complex comprising a pair of centrioles and a cloud of pericentriolar materials is located at the point of covergence of the microtubules of the mitotic apparatus. The in vitro assembly of microtubules was observed onto these complexes in the 1,400 g supernatant fraction of colcemid-blocked, mitotic HeLa cells lysed into solutions containing tubulin and Triton X-100. Dark-field mic...

Using Monte Carlo simulations, we have studied the self-organizing polydomain structure appearing at low temperatures in a square lattice-gas model with a repulsive nearest-neighbor interaction when the particle jumps are biased by a uniform electric field. These investigations confirm that the enhanced interfacial material transport is able to preserve the anisotropic self-organizing domain st...

Introduction: Crosstalk is a leakage of X-ray or light produced in a matrix of X-ray detectors or array of photodiodes in one element to other elements affecting on image contrast and spatial resolution. In this study, we assessed X-ray crosstalk in a computed tomography (CT) scanner with small detector elements to estimate the effect of various parameters such as X-ray tube voltage, detector e...
