Convolutional neural networks applied to differential dynamic microscopy reduces noise when quantifying heterogeneous dynamics.

Differential dynamic microscopy (DDM) typically relies on movies containing hundreds or thousands of frames to accurately quantify motion in soft matter systems. Using movies much shorter in duration produces noisier and less accurate results. This limits the applicability of DDM to situations where the dynamics are stationary over extended times.

The Typical Damage Form and Mechanism of a Railway Prestressed Concrete Sleeper.

Prestressed concrete sleepers are an important track component that is widely used in railway ballast track. Prestressed concrete sleepers have high strength, strong stability, and good durability; thus, their operation and use in railways are beneficial. However, in different countries and regions, certain damage to sleepers typically appears.

Two-color differential dynamic microscopy for capturing fast dynamics.

Differential dynamic microscopy (DDM) is increasingly used in the fields of soft matter physics and biophysics to extract the dynamics of microscopic objects across a range of wavevectors by optical microscopy. Standard DDM is limited to detecting dynamics no faster than the camera frame rate. We report on an extension to DDM where we sequentially illuminate the sample with spectrally distinct light and image with a color camera.

Structural analysis and identification of cis-elements of rice osRACD gene.

The osRACD gene correlated with fertility transformation in the photoperiod sensitive genic male sterile rice (PGMR), Nongken 58S, encoded a rice (Oryza sativa L. ssp. japonica) small GTPase belonging to the Rac/Rho family.

Preprophase band loses its function as a cytokinetic apparatus in mitosis of neck canal mother cell.

Preprophase bands in the neck canal mother cell and the central cell of the archegonium of the fern Dryopteris crassirhizoma are observed with immunofluorescence microscopy. No phragmoplast is found during mitosis of the neck canal mother cell; however, the phragmoplast develops very well in the central cell. The neck canal mother cell undergoes karyokinesis but not cytokinesis and finally produces only one binucleate neck canal cell.
