The interaction-driven starburst contribution to the cosmic star formation rate density
, 2013 An increasing amount of observational evidence supports the notion that there are two modes of star formation: a quiescent mode in disk-like galaxies, and a starburst mode, which is generally interpreted as driven by merging.

How Do Uncertainties in Galaxy Formation Physics Impact Field-level Galaxy Bias?
The Astrophysical JournalOur ability to extract cosmological information from galaxy surveys is limited by uncertainties in the galaxy–dark matter halo relationship for a given galaxy population, which are governed by the intricacies of galaxy formation.

, 2014 We present an analysis of the metallicity and star formation activities of HII regions in the interacting system Arp 86, based on the first scientific observation of the multi-object spectroscopy on the 2.16m Telescope at Xinglong Observatory.

A LAW FOR STAR FORMATION IN GALAXIES [PDF]
The Astrophysical Journal, 2011 We study the galactic-scale triggering of star formation. We find that the largest mass-scale not stabilized by rotation, a well defined quantity in a rotating system and with clear dynamical meaning, strongly correlates with the star formation rate in a wide range of galaxies.

ESC Heart Failure, EarlyView.This state‐of‐the‐art review outlines a practical, evidence‐based framework for early acute heart failure management to address critical gaps in current guidance and improve early treatment outcomes. Key components include early identification of co‐existing conditions, bedside haemodynamic profiling, a structured diagnostic approach incorporating both

Food Safety and Health, EarlyView.ABSTRACT Antioxidants in foods delay or prevent the oxidation of the food. Previously, synthetic antioxidants were commonly used in food formulations, but, due to safety concerns, interest in natural antioxidants has intensified. A novel microwave‐assisted drying extraction process was adopted to dry mint and coriander leaves.

The transformation of Spirals into S0 galaxies in the cluster environment
Frontiers in Astronomy and Space Sciences, 2015 We discuss the observational evidences of the morphological transformation of Spirals into S0 galaxies in the cluster environment exploiting two big databases of galaxy clusters: WINGS (0 ...

The decade of galaxy formation: pitfalls in the path ahead
, 2010 At the turn of the decade we arguably move from the era of precision cosmology to the era of galaxy formation. One approach to this problem will be via the construction of comprehensive galaxy samples. In this review I take the opportunity to highlight a

Massive Neutrinos and Galaxy Formation
, 1994 We report the most recent results from high-resolution numerical simulations of structure formation in two flat cold+hot dark matter models with neutrino mass densities $\onu=0.2$ and 0.3. We find that structure forms too late in all CDM+HDM models with $
