We discuss a doubly-holographic prescription for black holes in braneworlds with vanishing cosmological constant. It involves calculating Ryu-Takayanagi surfaces AdS funnel spacetimes attached to braneworld the $ critical$ Randall-Sundrum II model. Critical have virtue of having massless gravitons. Our approach should be useful when is hole interacting deconfined, large-$N$ matter. In higher di...
A key open question in the understanding of the biology of DNA methylation relates to the origin and function of CpG islands, stretches of GC-rich and relatively CpG-rich DNA sequence that often colocalize with promoter regions. All housekeeping, but also a substantial minority of tissue-specific genes are associated with the CpG islands. Limited experimental evidence suggests that CpG islands ...
Island biogeography has greatly contributed to our understanding of the processes determining species' distributions. Previous research has focused on the effects of island geography (i.e., island area, elevation, and isolation) and current climate as drivers of island species richness and endemism. Here, we evaluate the potential additional effects of historical climate on breeding land bird r...
We consider a perturbation of the Anosov-type system, which leads to the appearance of a hierarchical set of islands-around-islands. We demonstrate by simulation that the boundaries of the islands are sticky to trajectories. This phenomenon leads to the distribution of Poincaré recurrences with power-like tails in contrast to the exponential distribution in the Anosov-type systems.
Single-crystal percentage of graphene islands on Cu foil is associated with island sizes and shapes. In polycrystalline islands, certain grain boundary types are favored. There is no obvious relation between the number of lobes and grain orientations. An observed structure evolution and surface disorder of Cu grains can be possible factors for the formation of grain boundaries within graphene i...
