Rana lutea is one of the two anuran species described in 1782 by the Chilean born priest and naturalist Juan Ignacio Molina, and its nomenclatural history is confusing. After a detailed revision of the pertinent literature, we demonstrate that Bufo thaul Schneider, 1799, is a junior objective synonym of Rana lutea Molina, 1782, but based on the usage of both nomina, we revert the precedence and...

The goal of Artificial Intelligence, broadly defined, is to understand and engineer intelligent systems. This entails building theories and models of embodied minds and brains -both natural as well as artificial. The advent of digital computers and the parallel development of the theory of computation since the 1950s provided a new set of tools with which to approach this problem -through analy...

nic gases exsolved from magmas (Symonds et al. 1994). Thus, Ionian volcanic gases exsolved from magmas during eruption may also chemically We use thermochemical equilibrium calculations to show equilibrate (see below). that SO is expected in volcanic gases erupted on Io, and derive We modeled volcanic gas chemistry on Io in the 1000–2000 K range the range of temperatures, pressures, and element...

To what extent can brain-based investigations inform research on metacognition? Most view metacognition as a set of intricately complex and dynamic processes — such as those involved in insight, cognitive control, and mnemonic strategies. As such, metacognitive research has been thoroughly interdisciplinary, influencing educational, cognitive, developmental, and clinical investigations (see Hac...

We study the elliptic Cn and BCn Ruijsenaars-Schneider models which is elliptic generalization of system given in [1]. The Lax pairs for these models are constructed by Hamiltonian reduction technology. We show that the spectral curves can be parameterized by the involutive integrals of motion for these models. Taking nonrelativistic limit and scaling limit, we verify that they lead to the syst...

Comodule algebras of a Hopf algebroid H with a bijective antipode, i.e. algebra extensions B ⊆ A by H, are studied. Assuming that a lifted canonical map is a split epimorphism of modules of the (non-commutative) base algebra of H, relative injectivity of the H-comodule algebra A is related to the Galois property of the extension B ⊆ A and also to the equivalence of the category of relative Hopf...

In this report, we present the case of a 64-year-old woman who sustained a Burch-Schneider cage fracture. Prior to this event, she underwent repeated acetabular reconstructions, but in the end prosthesis removal was performed as a salvage procedure. We believe that the primary cause of the fracture was metal fatigue facilitated by intraoperative re-contouring of the flange, as well as reuse of ...

Rothblum, U.G., H. Schneider and M.H. Schneider, Characterizations of max-balanced flows, Discrete Applied Mathematics 39 (1992) 241-26!. Let G=( V, A) be a graph with vertex set V and arc set A. Aflow for G is an arbitrary real-valued function defined on the arcs A. A flow f is called max-balanced if for every cut W, 0f WC V, the maximum flow over arcs leaving W equals the maximum flow over ar...

Cells exposed to genotoxic stress, such as ionizing radiation and DNA damaging reagents, either arrest the cell cycle to repair the genome, or undergo apoptosis, depending on the extent of the DNA damage. DNA damage also has been implicated in various differentiation processes. It has been reported that gamma-ray exposure or treatment with DNA-damaging agents could induce myogenic differentiati...
