Utilizing scanning electron microscope, X-ray diffraction (XRD) and microhardness tests, we evaluated how various physiological environments affect the hydration behavior and physical properties of mineral trioxide aggregate (MTA). We found that the microstructure of hydrated MTA consists of cubic and needle-like crystals. The former comprised the principal structure of MTA, whereas the later w...

Although the space between stars in our galaxy appears to be completely empty of matter, there exists a very dilute gas even in “empty” space. This interstellar (meaning “between the stars”) medium varies in density (the amount of matter within a certain volume). Typical densities in the interstellar medium are one particle per cubic centimeter. Since hydrogen is the most single common element ...

Cubosomes are the nanoparticles of bicontinuous, lyotropic cubic phases, comprised curved lipid bilayers organized into a three-dimensional honeycomb (cavernous) like structures separating two internal aqueous channels and large interfacial area. Cubic phases optically isotropic, very viscous, solid-like (crystalline) with crystallographic symmetry. They can encapsulate hydrophilic, hydrophobic...

We show that parity is conserved in vector-like supersymmetric theories, such as supersymmetric QCD with massive quarks with no cubic couplings among chiral multiplets, based on fermionic path-integrals, originally developed by Vafa and Witten. We also look into the effect of supersymmetric breaking through gluino masses, and see that the parity-conservation is intact also in this case. Our con...

Racah-Wigner type of calculus is adapted to the system of two free electrons in a cubic box, confined to a single star p00 of quasimomentum. Various coupling schemes (LS-like, jj-like, and transitive) have been reviewed in analogy to the case of a free atom. Racah recoupling matrices are calculated explicitly, and their quantum-mechanical mewling is exposed in terms of octahedral multipoles. PA...

This paper provides a new generalization of fuzzy finite state machines, fuzzy transformation semigroups and their relationship. Consider a cubic structure, we introduce cubic finite state machines, cubic transformation semigroups, cubic successor, cubic exchange properties cubic subsystems, cubic submachines, cubic q-twins, cubic retrievable and study fundamental properties of them. We provide...

We study conformational transitions of simple coarse-grained models for protein-like heteropolymers on the simple cubic lattice and off-lattice, respectively, by means of multicanonical sampling algorithms. The effective hydrophobic/polar models do not require the knowledge of the native topology for a given sequence of residues as input. Therefore these models are eligible to investigate gener...

Recently cubic (c-) GaN/InxGa1-xN/GaN double heterostructures and quantum wells have been grown by MBE and MOCVD [1-3]. Contrary to their hexagonal counterparts, the cubic structures can be grown free from modulation due to spontaneous polarization and strain-induced piezoelectric fields. The spatial separation of the carriers wave function, induced by the quantum-confined Stark effect in the h...

We report the thermal conductivity of amorphous, cubic, and hexagonal Ge 2 Sb Te 5 using time-domain thermoreflectance from 80 to 500 K. The measured conductivities are 0.20 W m −1 K for amorphous , 0.63 cubic phase, 1.45 phase at room temperature. For increases monotonically with temperature when T < 300 K, showing a typical glass-like dependence, dramatically after heating up 435 due parti...
