Masquerade or Masquerader may refer to:
Masquerade is the second single by Kaya (ex-Schwarz Stein) released on September 6th, 2006. The single peaked at 13th on the Oricon Indies charts during the first week of its release.
The title track "Masquerade" is an upbeat jazz number while the coupling track "Psycho Butterfly" pulls Kaya back to his electronic/digital-gothic roots. Like his first single "Kaleidoscope", both tracks on "Masquerade" were composed by ex-Velvet Eden's KALM.
Masquerade (Russian: Маскарад) is a verse play written in 1835 by the Russian Romantic writer Mikhail Lermontov. The four-act play, set in 1830's St. Petersburg aristocratic society, highlights the rebellious spirit and noble mind of the protagonist, Yevgeny Arbenin. It is often compared with Shakespeare's Othello in its essential story line.
The hero of the drama, Arbenin, is a wealthy young man endowed with a rebellious spirit and a strong will. Born into high society, he strives in vain to gain independence and freedom. He lives by the laws of his society, and, in trying to defend his honor while blinded by jealousy and pride, ends up murdering his wife.
Act I opens with Arbenin and Prince Zvezdich playing cards. From there the pair go to a masquerade party also being attended by Arbenin's wife, Nina. Zvezdich flirts with a dissolute lady, a baroness who is a friend of Nina. But because of the masks Zvezdich does not know who she is. The mystery lady gives Zvezdich her bracelet as a memento - a bracelet that had once belonged to Nina. Arbenin later notices the bracelet missing from his wife's wrist, recalls it in Zvezdich's possession, and concludes that his wife has been cheating on him with Zvezdich.
PARSEC is a package designed to perform electronic structure calculations of solids and molecules using density functional theory (DFT). The acronym stands for Pseudopotential Algorithm for Real-Space Electronic Calculations. It solves the Kohn–Sham equations in real space, without the use of explicit basis sets.
One of the strengths of this code is that it handles non-periodic boundary conditions in a natural way, without the use of super-cells, but can equally well handle periodic and partially periodic boundary conditions. Another key strength is that it is readily amenable to efficient massive parallelization, making it highly effective for very large systems.
Its development started in early 1990s with James Chelikowsky (now at the University of Texas), Yousef Saad and collaborators at the University of Minnesota. The code is freely available under the GNU GPLv2. Currently, its public version is 1.3.6. Some of the physical/chemical properties calculated by this code are: Kohn–Sham band structure, atomic forces (including molecular dynamics capabilities), static susceptibility, magnetic dipole moment, and many additional molecular and solid state properties.
