Near-Boundary and Bulk Regions of a Semi-Infinite Two-Dimensional Heisenberg Antiferromagnet
N. Voropajeva, A. Sherman
Using the spin-wave approximation elementary excitations of a semi-infinite two-dimensional Heisenberg antiferromagnet are considered. The spectrum consists of bulk mod…
Dust-corrected surface photometry of M 31 from the Spitzer far infrared observations
Elmo Tempel, Antti Tamm, Peeter Tenjes
We create a model for recovering the intrinsic, absorption-corrected surface brightness distribution of a galaxy and apply the model to the M31. We construct a galactic model as a…
On approximation of smoothing probabilities for hidden Markov models
J. Lember
We consider the smoothing probabilities of hidden Markov model (HMM). We show that under fairly general conditions for HMM, the exponential forgetting still holds, and the smoothin…
"Dynamical" interactions and gauge invariance
R. Saar, S. Groote, H. Liivat +1
Appreciating the classical understanding of the elementary particle the "dynamical" Poincare algebra is developed. It is shown that the "dynamical" Poincare algebra and the equatio…
Probing scalar particle and unparticle couplings in e+ e- -> t tbar with transversely polarized beams
S. Groote, H. Liivat, I. Ots +1
In searching for indications of new physics scalar particle and unparticle couplings in e^+ e^- \to t\bar t, we consider the role of transversely polarized initial beams at e^+ e^-…
Standard deviation of the longest common subsequence
Jüri Lember, Heinrich Matzinger
Let be the length of the longest common subsequence of two independent i.i.d. sequences of Bernoulli variables of length . We prove that the order of the standard deviatio…
