Effect of preservation procedures on the body shape of the golden mojarra, Diapterus aureolus (Actinopterygii: Perciformes: Gerreidae), and its repercussions in a taxonomic study [PDF]
Background. In taxonomic studies of fish, the use of preserved samples has been a common practice. Under the framework of morphometrics, the effect of the preservation techniques on body shape is rarely taken into account. Changes during preservation can

The Two-fold Role of Observables in Classical and Quantum Kinematics [PDF]
Observables have a dual nature in both classical and quantum kinematics: they are at the same time \emph{quantities}, allowing to separate states by means of their numerical values, and \emph{generators of transformations}, establishing relations between

Black Noise, White Ears: Resilience, Rap, and the Killing of Jordan Davis
I speak out of direct and particular anger at an academic conference, and a white woman comes up and says, “Tell me how you feel but don’t say it too harshly or I cannot hear you.” But is it my manner that keeps her from hearing, or the threat of a ...

Taming the rugged energy landscape: Techniques for the production, reordering, and stabilization of selected cluster inherent structures [PDF]
We report our studies of the potential energy surface (PES) of selected binary Lennard-Jones clusters. The effect of adding selected impurity atoms to a homogeneous cluster is explored.

Multipoint, high time resolution galactic cosmic ray observations associated with two interplanetary coronal mass ejections [PDF]
[1] Galactic cosmic rays (GCRs) play an important role in our understanding of the interplanetary medium (IPM). The causes of their short timescale variations, however, remain largely unexplored. In this paper, we compare high time resolution, multipoint

Phase changes in selected Lennard-Jones X_{13-n}Y_n clusters [PDF]
Detailed studies of the thermodynamic properties of selected binary Lennard-Jones clusters of the type X_{13-n}Y_n (where n=1,2,3) are presented. The total energy, heat capacity and first derivative of the heat capacity as a function of temperature are ...

Splitting of operations for alternative and Malcev structures [PDF]
In this paper we define pre-Malcev algebras and alternative quadri-algebras and prove that they generalize pre-Lie algebras and quadri-algebras respectively to the alternative setting.
