Correlated disorder in myelinated axons orientational geometry and structure

, 2017
While the ultrastructure of the myelin has been considered to be a quasi-crystalline stable system, nowadays its multiscale complex dynamics appears to play a key role for its functionality, degeneration and repair processes following neurological ...

Noncanonical Nucleotides in the Genome Around the Maternal‐Zygotic Transition

Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
In this paper, Kazzazi et al. provide a comprehensive review of the dynamics of nonconventional nucleotides in the genome during early developmental stages, hypothesizing a potential role for these nucleotides in the activation of the zygotic genome. ABSTRACT From the very moment of fertilization and throughout development, the cells of animal embryos ...

Path Planning of Unmanned Aerial Vehicles Based on an Improved Bio-Inspired Tuna Swarm Optimization Algorithm

Biomimetics
The Sine–Levy tuna swarm optimization (SLTSO) algorithm is a novel method based on the sine strategy and Levy flight guidance. It is presented as a solution to the shortcomings of the tuna swarm optimization (TSO) algorithm, which include its tendency to

Matsumura‐Type Estimates and Global Solutions of a Fractional Wave Equation With Nonlocal Nonlinearity

Mathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT The main results of this paper are the global existence and long time behavior of solutions of a fractional wave equation with a nonlocal nonlinearity. The techniques in this work rely on norm estimates of the solutions of εutt+ut+(−Δ)βu=0,u(0,x)=φ(x),ut(0,x)=ψ(x),$$ \varepsilon {u}_{tt}+{u}_t+{\left(-\Delta \right)}^{\beta }u=0,\kern1em u ...

The interplay between landscape change and plasticity in habitat selection determines dispersal movements and settlement in small non‐flying vertebrates

Oikos, EarlyView.
The response of dispersers to landscape changes depends on both external environmental conditions and individual internal conditions, as well as movement and orientation abilities. Plasticity in habitat selection may also affect how individuals respond to landscape changes.

Levy Flights in Inhomogeneous Media

, 2003
We investigate the impact of external periodic potentials on superdiffusive random walks known as Levy flights and show that even strongly superdiffusive transport is substantially affected by the external field.

Assessing physiological, behavioral and movement responses to Suprelorin implant delivery methods in free‐ranging eastern grey kangaroos Macropus giganteus

Wildlife Biology, EarlyView.
Overabundant populations of eastern grey kangaroos Macropus giganteus in peri‐urban areas pose ecological and social challenges. Current management strategies are often hindered by animal welfare and logistical concerns. This study aimed to assess stress responses of kangaroos to two contraceptive delivery methods.
