This article describes the history of the optical microscope. The convex lens, an important component of the microscope, was already in use during the ancient era as a tool to create fire from sunlight. The quality of the lens improved in the 11th and 12th centuries and had begun to be used as a microscope component by the end of the 16th century. In the 17th century, innovation of the optical microscope accelerated the study of biological specimens. Robert Hooke designed a two-lens microscope and observed various microorganisms. He published “Micrographia” in 1665, in which the term “cell” first appeared. Another contributor to the microscope in the same period was Leeuwenhoek, who constructed a single lens microscope and discovered bacteria. In 1857, Zeiss, with the cooperation of Abbe and Schott, manufactured a stand type modern microscope that achieved a spatial resolution of 0.2 μm. Their microscope significantly contributed to subsequent discoveries in medical biology. Due to the wave nature of light, the spatial resolution of an ordinary microscope is limited to 0.2 μm. To overcome this limitation, various microscope configurations such as a two-photon laser-scanning microscope, a near-field scanning optical microscope, and a photoactivated localization microscope were developed. For the nonstaining visualization of biological specimens, optical microscopy utilizing a nonlinear optical phenomenon was proposed. Currently, the second harmonic generation microscope and the coherent Raman scattering microscope are widely used and several examples of these microscopic results are presented in this article.

 

Analysis of Flexible Insertion Assembly of Polygonal Pegs

Insertion assembly of polygonal pegs exhibits distinct mating process compared to that for conventional round pegs and holes. Their inherent orientation characteristic increases the degree of complexity of the assembly tasks and limits completion of the insertion assembly. This paper is devoted to analysis of motion behavior of the polygonal peg-hole insertion to clarify constraint conditions for successful insertion assembly. Effective regions for possibly successful insertion assembly on the chamfer surface will also be presented. Therefore, appropriate manipulation strategies can be concluded and automated polygonal insertion assembly becomes realizable in the future.

The paper provides a brief introduction to the near-wall problem of LES and how it can be solved through modeling of the near-wall turbulence. The distinctions and key differences between different approaches are emphasized, both in terms of fidelity (LES, wall-modeled LES, and DES) and in terms of different wall-modeled LES approaches (hybrid LES/RANS and wall-stress-models). The focus is on approaches that model the wall-stress directly, i.e., methods for which the LES equations are formally solved all the way down to the wall. Progress over the last decade is reviewed, and the most important and promising directions for future research are discussed.
