Three-dimensional phase-field simulations are employed to investigate rod-type eutectic growth morphologies in confined geometry. Distinct steady-state solutions are found to depend on this confinement effect with the rod array basis vectors and their included angle (α) changing to accommodate the geometrical constraint. Specific morphologies are observed, including rods of circular cross secti...

We report high resolution angle-resolved photo-emission spectroscopy (ARPES)measurements of detwinned FeSe single crystals. The application of amechanical strain is used to promote the volume fraction of one of the orthorhombic domains in the sample, whichwe estimate to be 80% detwinned. While the full structure of the electron pockets consisting of two crossed ellipsesmay be observed in the te...

The present paper describes a sequential study of the leukocyte profiles and the changes in morphometry and morphology of erythrocytes in the tadpoles of Polypedates teraiensis during their development and metamorphosis, that is, transfer from an aquatic mode to a terrestrial mode of life. Blood smears of 21 different stages (Gosner stage 26 to 46) of tadpoles were investigated. Population of e...

We investigate the current flow of microcavity polariton condensates loaded into concentric ring-shaped potentials. The tunneling between different potential rings results in phase-locked states, depending on separation rings. As a consequence, condensate currents can either same or opposite direction specific configuration In two standard potentials, always circulate (co-flowing current) and v...

Understanding the process of the self-assembly of gigantic polyoxometalates and their subsequent molecular growth, by the addition of capping moieties onto the oxo-frameworks, is critical for the development of the designed assembly of complex high-nuclearity cluster species, yet such processes remain far from being understood. Herein we describe the molecular growth from {Mo150 } and {Mo120 Ce...

Sperm head morphology has been identified as a characteristic that can be used to predict a male's semen quality. In the present study, we have developed an automated sperm head morphology analysis (ASMA) plug-in for open-source ImageJ software (http://rsbweb.nih.gov/ij/). We describe the plug-in's functionality, and confirm its validity for sperm head morphology analysis using fish sperm. Sper...

Elliptical elements are essential optical surfaces for modifying systems. For polishing the whole elliptical surface using doughnut-shaped MCF tool with variable tilt angle, an experimental investigation was conducted in this work. Firstly, a flat workpiece polished to determine feasibility. It found that middle portion of had optimal ability remove materials, and roughness Sa at material remov...

The performance of clustering algorithms for image segmentation are highly sensitive to the features used and types of objects in the image, which ultimately limits their generalization capability. This provides strong motivation to investigate integrating shape information into the clustering framework to improve the generality of these algorithms. Existing shape-based clustering techniques ma...

New approximate local DtN boundary conditions are proposed to be applied on ellipticalor prolate-spheroid exterior boundaries when solving respectively twoor three-dimensional acoustic scattering problems by elongated obstacles. These new absorbing conditions are designed to be exact for the first modes. They can be easily incorporated in any finite element parallel code while preserving the lo...
