The Tully-Fisher Zero Point Problem

, 2008
A long standing problem for hierarchical disk galaxy formation models has been the simultaneous matching of the zero point of the Tully-Fisher relation and the galaxy luminosity function (LF).

Innovation Diffusion Among Case‐Based Decision‐Makers

Journal of Economics &Management Strategy, EarlyView.
ABSTRACT This paper analyzes a model of innovation diffusion with case‐based individuals a la Gilboa and Schmeidler, who decide whether to consume an incumbent or a new product based on their and their social neighbors' previous consumption experiences. I analyze how diffusion patterns change with individual characteristics, innovation characteristics,

Stellar Mergers or Truly Young? Intermediate-age Stars on Highly Radial Orbits in the Milky Way’s Stellar Halo

The Astrophysical Journal
Reconstructing the mass assembly history of the Milky Way relies on obtaining detailed measurements of the properties of many stars in the galaxy, especially in the stellar halo.

Proteomic analysis of the zone of degeneration at the mitosis–meiosis transition stage in wild‐caught male catshark (Scyliorhinus canicula), correlated with an unusually high‐water temperature in the English Channel

Journal of Fish Biology, EarlyView.
Abstract In the context of current global change, variations in water temperature are one of the environmental conditions with serious consequences for marine life, including reproductive processes. In the small spotted catshark Scyliorhinus canicula, spermatogenesis occurs in spermatocysts composed of synchronously developing germ cells associated ...

Women Directors and R&D Investment in Family Firms: The Mediating Role of Debt Financing

Journal of Product Innovation Management, EarlyView.
ABSTRACT Although research examining the role of women directors in fostering innovation within family firms continues to expand, the mechanisms underlying their influence remain insufficiently understood. This study examines the mediating role of debt financing in the relationship between women directors and R&D investment.

The Chemical Evolution of Narrow Emission Line Galaxies: the Key to their Formation Processes The Chemical Evolution of Narrow Emission Line Galaxies: the Key to their Formation Processes

Acta Universitaria, 2012
Utilizando la mayor muestra de galaxias con líneas de emisión angostas disponible hasta el momento, se muestra que sus características espectrales están correlacionadas con diferentes parámetros físicos, como las abundancias químicas, las morfologías ...

Galaxy Assembly Bias in the Stellar-to-halo Mass Relation for Red Central Galaxies from SDSS

The Astrophysical Journal
We report evidence of galaxy assembly bias—the correlation between galaxy properties and biased secondary halo properties at fixed halo mass ( M _H )—in the stellar-to-halo mass relation for red central galaxies from the Sloan Digital Sky Survey.
