Uncertainties in Galactic Chemical Evolution Models [PDF]
We use a simple one-zone galactic chemical evolution model to quantify the uncertainties generated by the input parameters in numerical predictions for a galaxy with properties similar to those of the Milky Way.

Chemical evolution models with a new stellar nucleosynthesis [PDF]
Numerical models for the chemical evolution of the Galaxy have been computed with the new stellar yields published by Maeder (1992). These metallicity dependent yields represent an important improvement in the chemical evolution of galaxies but there are

Modification of N-terminal α-amine of proteins via biomimetic ortho-quinone-mediated oxidation
Methods for selective modification of the N-terminus of proteins are of high interest, but mostly require specific amino acid residues. Here, the authors report a selective and fast method for N-terminal modification of proteins based on quinone-mediated

Coupling emitted light and chemical yields from stars: a basic constraint to population synthesis models of galaxies [PDF]
In this paper we emphasize the close connection between the chemical and spectrophotometric evolution of stellar systems: Chemical yields from stars correspond to a precise fraction of their emitted light.

Quasi-Chemical Theory and Implicit Solvent Models for Simulations [PDF]
A statistical thermodynamic development is given of a new implicit solvent model that avoids the traditional system size limitations of computer simulation of macromolecular solutions with periodic boundary conditions.

PNNARMA model: an alternative to phenomenological models in chemical reactors [PDF]
This paper is focused on the development of non-linear neural models able to provide appropriate predictions when acting as process simulators. Parallel identification models can be used for this purpose.

Galactic chemical evolution: Stellar yields and the initial mass function [PDF]
We present a set of 144 Galactic chemical evolution models applied to a Milky Way analogue, computed using four sets of low+intermediate star nucleosynthetic yields, six massive star yield compilations, and six functional forms for the initial mass ...
