Understanding axon guidance: attraction, repulsion, and statistical physics
Understanding axon guidance is important for developing therapies to restore neuronal connections damaged by injury or disease. Axons migrate in response to extracellular guidance molecules that induce or inhibit axon outgrowth activity within the axon.

Motion noise changes directional interaction between transparently moving stimuli from repulsion to attraction. [PDF]
To interpret visual scenes, visual systems need to segment or integrate multiple moving features into distinct objects or surfaces. Previous studies have found that the perceived direction separation between two transparently moving random-dot stimuli is

Fast efficient coding and sensory adaptation in gain-adaptive recurrent networks [PDF]
As the statistics of sensory environments often change, neural sensory systems must adapt to maintain useful representations. Efficient coding prescribes that neuronal tuning curves should be optimized to the prior, but whether they can adapt rapidly is ...

Mislocalization of visual stimuli: independent effects of static and dynamic attention. [PDF]
Shifts of visual attention cause systematic distortions of the perceived locations of visual objects around the focus of attention. In the attention repulsion effect, the perceived location of a visual target is shifted away from an attention-attracting ...

Bistability and Switching Behavior in Moving Animal Groups
Moving animal groups such as schools of fish and flocks of birds frequently switch between different group structures. Standard models of collective motion have been used successfully to explain how stable groups form via local interactions between ...

Existence of bounded global solutions for fully parabolic attraction-repulsion
This article concerns the parabolic attraction-repulsion chemotaxis system with signal-dependent sensitivities $$\displaylines{ u_t=\Delta u-\nabla \cdot (u\chi(v)\nabla v) +\nabla \cdot (u\xi(w)\nabla w), \quad x \in \Omega,\; t>0, \cr v_t=\Delta v-v ...

Transition mechanisms of translational motions of bubbles in an ultrasonic field
The translation behaviors of oscillating bubbles are closely related to the polymerizations and dispersions between them, which are crucial for the ultrasonic cavitation effect.

Temporary Behavioral Responses to Playbacks by a Pest Parrot and Implications for Management [PDF]
Human-wildlife interactions continue to increase due to anthropogenic disturbances, with some interactions resulting in conflict. Leveraging a taxa’s bias for a particular sensory cue is a promising management avenue for reducing the potential and ...

Antigravity, an Answer to Nature’s Phenomena including the Expansion of the Universe
The gravitational attraction force being proportional to the mass has been experimentally shown for several hundred years now, but no gravitational repulsion has been identified within the accepted scientific reasoning.
