NUCLEOSOME ORGANIZATION IN PLANT DNA SATELLITES by V. N. Babenko, K. O. Kutashev, V. F. Matvienko

“…As many as 50 % of the monomers have a periodicity of DNA bends in the vicinity of 170 bp, fitting the wrapping length of a single nucleosome within two highest-order harmonics in the DNA curvature profile. The nucleosome positioning scheme in subtelomeric satellites in plants differs from that in centromeric satellites.…”

Generalized α-Attractor Models from Elementary Hyperbolic Surfaces by Elena Mirela Babalic, Calin Iuliu Lazaroiu

“…For each elementary surface, we discuss its decomposition into canonical end regions and give an explicit construction of the embedding into the Kerekjarto-Stoilow compactification (which in all three cases is the unit sphere), showing how this embedding allows for a universal treatment of globally well-behaved scalar potentials upon expanding their extension in real spherical harmonics. For certain simple but natural choices of extended potentials, we compute scalar field trajectories by projecting numerical solutions of the lifted equations of motion from the Poincaré half plane through the uniformization map, thus illustrating the rich cosmological dynamics of such models.…”
