UNLABELLED Fluorosis is one of the factors which bring about mineralisation changes in a dentinal structure leading to dentin. The purpose of the present study was to compare and evaluate the dentinal tubular changes in fluorosed and nonfluorosed teeth subsequent to the application of citric acid,strontium acetate based sodium fluoride (SAF) using scanning electron microscopy (SEM). Dentin spec...

The prolamellar body (PLB) appears in the etioplasts of dark-grown higher plants (3, 16, 18, 21). I t has a well-defined structure consisting of a central core built of an array of interconnected tubules, from which peripheral tubular elements extend into the plastid matrix. The tubular elements of the central core can be arranged in a crystalline (3, 7) or random pattern (19). The peripheral e...

In this paper, we propose a novel tubular structure segmentation method, which is based on an intensity-based tensor that fits to a vessel. Our model is initialized with a single seed point and it is capable of capturing whole vessel tree by an automatic branch detection algorithm. The centerline of the vessel as well as its thickness is extracted. We demonstrated the performance of our algorit...

Periodic truss-lattice materials, especially when combined with current additive manufacturing techniques, are attracting attention in lightweight material engineering. As a member of the elementary cubic truss family, simple-cubic lattice possesses highest stiffness and strength along principal directions plays an important role load-bearing mechanical metamaterials. High anisotropic propertie...

The inverse protein folding problem is that of designing an amino acid sequence which has a prescribed native protein fold. This problem arises in drug design where a particular structure is necessary to ensure proper protein-protein interactions. Previously, tubular structures for a three-dimensional (3D) hexagonal prism lattice were introduced and their stability was formally proved for simpl...
