Dynamical Regularities in Galaxies
, 2019 Galaxies are observed to obey a strict set of dynamical scaling relations. We review these relations for rotationally supported disk galaxies spanning many decades in mass, surface brightness, and gas content. The behavior of these widely varied systems can be summarized with a handful of empirical laws connected by a common acceleration scale.

The Public Character of Church in the Digital Age☆
International Journal of Systematic Theology, EarlyView.Abstract The rise of digital technology in recent decades has led to a rapid change of communication and interaction within society and its public dimensions. As this shift in the technological landscape raises theological questions about the appropriate ecclesial use of digital technology, it also touches upon fundamental questions about the church's ...

How Important Is the Home Market for Cross‐Listed Biotech Companies?
International Finance, EarlyView.ABSTRACT This study investigates five German biotechnology firms cross‐listed on XETRA and NASDAQ. By employing high‐frequency data, we estimate both bivariate and trivariate vector error correction models—the latter explicitly accounting for exchange rate dynamics—to assess which market, domestic or U.S., leads in price discovery.

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,

EMPRESS. XII. Statistics on the Dynamics and Gas Mass Fraction of Extremely Metal-poor Galaxies
The Astrophysical JournalWe present the demography of the dynamics and gas mass fraction of 33 extremely metal-poor galaxies (EMPGs) with metallicities of 0.015–0.195 Z _⊙ and low stellar masses of 10 ^4 –10 ^8 M _⊙ in the local universe.

Role of Gaseous Disk in the Formation of the Spiral Structure of the Milky Way Galaxy
Open Astronomy, 2016 We use observational gaseous and stellar density distributions in the disk of the Milky Way (MW) galaxy together with the disk rotation curve and measured disk velocity dispersion to build collisionless and combined collisionless-gaseous equilibrium ...

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 ...
