Giant cross-magnetic-field steps due to binary collisions between pair particles
Article explores giant cross-magnetic-field steps which occur as a result of positron-electron collisions. Within a constant magnetic field (e.g., 1 T), a collision between a positron and an electron can result in a correlated drift across the magnetic field for a continuous range of impact parameters. Within this range, drift distances orders of magnitude larger than that associated with like-charge collisions were observed by computer simulation.

Explicitly teaching five technical genres to English first-language adults in a multi-major technical writing course
In this article, the author reports the effects of explicitly teaching five technical genres to English first-language students enrolled in a multi-major technical writing course. Previous experimental research has demonstrated the efficacy of explicitly teaching academic writing to English first-language adults, but no comparable study on technical writing exists.

EMOTION-III Model: A Theoretical Framework for Social Empathic Emotions in Autonomous Control Systems
In this article, a theoretical model of social empathic emotion is derived based on the principles of survival by extending the maximization of self-gains to include others as an extended-self. This extended-self model of optimization for survival provides the computational mechanisms in the optimization process to maximize self-gains without minimizing the gains (or maximizing losses) for the other individuals. Thus, it can resolve conflicts in a competitive environment, and change the social dynamics into a cooperative interaction instead.

Space-charge-based electrostatic plasma confinement involving relaxed plasma species
In this article, a numerical study is reported on the equilibrium properties of a surface-emitted or edge-confined non-drifting plasma. A self-consistent finite-differences evaluation of the electrostatic potential is carried out for a non-neutral plasma that follows a Boltzmann density distribution.

Electrical Properties of Tin Selenide Under High-Pressure
The article investigates the pressure-induced phase transitions in tin selenide (SnSe). using the first-principles density functional calculations. The experimental results in the nanostructured SnSe revealed a phase transition at 4 GPa whereas that in the well-crystallized samples showed at 10 GPa.

Loitering at the hilltop on exterior domains
In this article, the author proves the existence of an infinite number of radial solutions of Δu+f(u)=0 on the exterior of the ball of radius R>0 centered at the origin and f is odd with f<0 on (0,β), f>0 on (β,δ), and f≡0 for u>δ. The primitive F(u)=∫u0f(t)dt has a "hilltop" at u=δ which allows one to use the shooting method and ODE techniques to prove the existence of solutions.

Cardiac and metabolic physiology of early larval zebrafish (Danio rerio) reflects parental swimming stamina
Article describes experiment in which mature adult zebrafish (Danio rerio) were subjected to a swimming performance test that allowed separation into low swimming stamina or high swimming stamina groups in order to determine if inherited traits that support enhanced swimming stamina in offspring appear only in juveniles and/or adults, or if these traits actually appear earlier in the morphologically quite different larvae.
