Abstract A finitely generated group

A number of 3-amino-1, 2, 4-triazin-5 (2H)- ones(1) were synthesized and condensed with a-haloketones to give 2,6-disubstituted imidazo [1, 2-b] [1, 2, 4]-triazin-3 (4H)-ones (2). These compounds were reacted further with a - haloketones to yield N-alkylated products (3).

<p style='text-indent:20px;'>Aiming at efficient solution of optimal control problems for continuous nonlinear time-delay systems, a multiple shooting algorithm with lifted Runge-Kutta integrator is proposed. This in implicit form to remove the restriction smaller integration step sizes compared delays. A tangential predictor applied such that Newton iterations required can be reduced con...

Non-Hermitian Hamiltonians provide an alternative perspective on the dynamics of quantum and classical systems coupled non-conservatively to environment. Once primarily interest mathematical physicists, theory non-Hermitian has solidified expanded describe various physically observable phenomena in optical, photonic, condensed matter systems. Self-consistent descriptions mechanics based have be...

The description of the dynamics strongly correlated quantum matter is a challenge, particularly in physical situations where quasiparticle absent. In such situations, however, many-body Kubo formula from linear response theory, involving matrix elements current operator computed with wave functions, remains valid. Working directly Hilbert space and not making any reference to quasiparticles (or...

This paper presents a proof of Stirling's formula using Haar wavelets and some properties of Hilbert space, such as Parseval's identity. The present paper shows a connection between Haar wavelets and certain sequences.

The morphology of retinal photoreceptor layer was studied in continuous light-exposed and dark-adapteddomestic male cats (Felis catus). The eyes of 12 healthy adult cats (4 in continuous light-exposed group, 4 in continuous dark-adapted group, and 4 in control group) were routinely fixed and studied by electron microscope. Results showed that the general structure of photoreceptor layer in this...
